Can I Connect a Potentiometer Rate at 2w to 20w LED with a 20w Resistor?

a better way to do it is with a power transistor eg 2n3055 (less than 1). Drive it from the pot between base and collector, with a resistor in series (say 20 ohms) to limit the maximum base current. Alternatively for a really clever dimmer that doesnt get hot, use a 555 timer to produce a fast pulse wave, and vary the duty cycle. Use the BUZ11, or a tip 29 transistor to turn the leds on and off fast so you dont see flicker - or slow it don and you get a strobe effect!

1. there's 100W bulbs and 200W bulbs?

He bought 9 100W bulbs only (72/8 = 9) OR He bought 6 200W bulbs only (72/12 = 6) If he bought bulbs of both kinds, then there is no way of knowing exactly how many of each kind did he buy. He could have bought 6 of 100W and 2 of 200W. (6*8 2*12 = 72) OR He could have bought 3 of 100W and 4 of 200W. (3*8 4*12 = 72) The problem could be put into an equation like this: 8x 12y = 72 And we know that x and y are whole and positive numbers. But to obtain the exact values for x and y, a second equation would be needed. That is, a second relation between the variables x and y.

2. planin 2 buy a 1000w woofer 600w amplifier 460w speakers is 600w amplifier good for it need help?

good choice.. man. use pioneer. system. you need to have a simple jumper to separate each frequency to tweeters, woofer and normal speaker.

3. Skip upgrading W8 Pro to W10 and install W10 and use key from W8 Pro?

TL;DRThe long story.Something happened, and my Windows 8.1 Pro stopped working and I had to reinstall it. I have a Windows 8 Pro installation DVD that I got from Amazon a few years back. I used it and installed Windows 8 Pro on my PC. Ultimately I wanted to upgrade to Windows 10 Pro, but it was taking too long to update Windows 8 to 8.1, so I installed Windows 10 Media Creation and created a bootable Windows 10 USB. Using the bootable USB, I installed Windows 10 Pro on my PC, and that is where the pain started. I did some googling and found that with Starting with W10 build 1511, you can use the W7 or W8 key on a clean install, but I could not find how to actually activate the fresh Windows 10 installation. After several tries to activate I finally called support and they helped me out.Note: A side effect of skipping the Windows 7/8 upgrade to Windows 10 is that support had to invalidate my Windows 8 product key and give a new key.

4. $W$ is $T$-invariant and showing that $W = N(T)$

Your idea is not off. Since $W$ and $N(T)$ have the same dimension, it suffices you show one is included in the other, in either direction. Given $win W$, note that $Twin Wcap R(T)$, so $Tw=0$. This means $Wsubseteq N(T)$.Consider now $k[X]$ for some field $k$, and define $p(X)mapsto p'(X)$. Then $

m im;T=k[X]$ so $k[X]=R(T)oplus 0$, but the kernel of this is nonempty

5. Can my laptop support W.O.W?

well, my laptop was intel i3 3.1 Ghz. pretty **** graphic card, 4 gb of ram and it ran WOW. and I suggest that when you start playing that you make a mage or a warlock. You are laptop should be able to run that, but you should go onto 'my computer' then system properties and find out what processer you have.

6. Is 5w20 oil ok for an engine that takes 10w30?

I am supposed to use 5W-30, but the last mechanic I went to said I should use 20W-50. Interestingly the manual clearly states "Do not use 20W-50 nor any other oil grade besides 5W-30 in this engine." So I said to the mechanic, "Uh, thanks. Uh, bye!" and never went back to him. Whenever a mechanic says he knows better than the vehicle manufacturer that's a clear sign that you need to go somewhere else. Yes, I understand that you can use different oil grades and still get by and that in different climates and with engine wear you may benefit from a different oil grade, but usually all that's covered in the owner's manual. For an example, in artic weather I should use 0W-30 instead of 5W-30 just as it says so in the manual.

Any ideas?ummm for the 90s...placed on dishevelled pants w/ a plaided shirt or some form of neon colored strolling suits.....for the 80s the problem with the leggings....etc....or u might desire to do like an 80s exercising recurring host with the only piece swim greater wholesome with leggings and a head band.------Why is one supposed to avoid white shoes after labor day?i have these cute white bermuda shorts and the other day my mom was like " you cant wear these after tomorow" and i was just lyk " what ever, lyk i care about some stupid rule" i make my own fashion rules!.... of course still following the basics and all the in stuff------Good ways to wear legwarmers?How about over high-heeled boots or shoes, like this: Instead of tights you can do skinny jeans as well. I think it looks cute. I saw a woman wearing black high-heeled boots with charcoal grey leg warmers over and indigo skinny jeans, and it looked great.------Hey im a gay guy and need some info on heels?I think guys sizes are two sizes smaller. I found some men's cowboy boots that I had to own - I wear a size 9 boots and the men's boots were 7. In a narrow width, they fit just as good as my others. Maybe try two size larger in a wider width? Hope this helps.------Could someone who loves and is really into shoes try to explain it to me?when i was around 10 i didnt get it either.. but as i grew older i understood why. Sometimes when you try on normal clothes they dont always fit the way you want it to, it gets frustrating. But its different with shoes, you just get your size down and they fit perfectly, with ease.------Would nude colored heels look good with black and white dress?Mmn- nude shoes with a black dress makes it a difficult one. Colours that 'Go' with black are Yellow, Red and obviously white but none on those really help nude shoes. Gold is yellow so that doesn't solve anything. Try black shoes and you can pick and choose your second colour (Perhaps make a statement)------What should i wear with this dress?OK so for the first one i would suggest wearing a long, black beaded necklace, or just a necklace. And other than that it's up to you.For the second one i would suggest a necklace. Also earrings would go great. For a purse, i think a clutch (black or Grey) would be good.------What to buy for homecoming?I recommend taking a look at the prom dress section on DressMob. DressMob is an online fashion community focused on dresses. You can chat and ask questions. Anyhow, if you look in the prom section and choose only cocktail length dresses in the search filter, I think you'll find lots of cute homecoming dresses!.------What kind of shoes should I wear with a red cocktail dress? Do women still wear fur coats?The sadals are prob fine as long as it is still pretty warm where you are. But wearing sandals and then a fur coat contradicts each other, so I would pick one or the other. Also, I wouldn't wear the fur coat as it would might offend some people that you might not want to.------How to train for a stiletto run (Girls please help)?inserts - Those are the secrets - you have to be very careful. If the heels break and you land the wrong way. are there any purely rubber stilettos? com - Just jam them into your foot if they do not fit. It wil help reduce the pounding that happens to your foot------Can you give fashion advice to help me win this bet?nice. sometimes there are just things you've got to say no to.sorry, i don't have any ideas of suits that would fit you in the shoulders (if you're a man your shoulders are obviously bigger) or dresses that would fit you well.perhaps borrowing a pair of your mother's panties?------Can anyone help me find combat boots!!!!!?Amazon has a few knee high, but thigh highs are a stumper. Hope these might help and good luck.------yo girl, what to wear for retail interviews?Do NOT wear 5 inch heels to an interview. That is very unprofessional!

The fishnets alone put it into this realm. People whose door you are knocking on won't consider it a joke. If you really want to wear the dress then wear black tights with the black shorts and flat ballerina shoes carrying your duster------Need a answer, ASAP...it's about pantyhose:)?I say see how it look with and without or just wear them no body notices tbh or you can cut off the toe bits and it will seem like you natural legs but be careful if you cut off since too much/too little may make them look weird and unnatural. Good luck :-)------Ladies, what kind of high heels do you like to wear?Hey there! I don't follow any brand names but when I go to work I am usually in a pair of 3" heels. I have different types for different outfits. When I go out with my hubby or we just are having sex, I wear the 5" stilettos! I have 6 different pairs of them.------Wearing high heels to high school?If I was at school I'd prefer to wear lower heeled shoes because of safety reasons. the boots you have sound nice but only for going out or something,you people are so lucky you don't have uniform, I'm from Australia and I wear the same thing everyday -.-"------What comes to mind when I say..?Third grade, my teacher, Valentine boxes, Valentine candy, and a crush I had on one of the boys. Good lunches, good schools, fun walking home with girls in my neighborhood and stopping by the drugstore for ice cream or a Coke in a glass with ice and THIN straws, not shotgun barrel sized ones------Quick Survey: Black hat, shoes, car, ...?1.keep it nice and shiny2.hold it and love it3.wear it and put hat pins on it to decorate it4.love to see a woman in5.make something out of wood6.use all of it's features7.it must be going to rain8.WOW baby you look good9.going to a funeral10.love it------what do you think of these shoes?I think they're great - I cant walk in big heels either so this is the type of heels I'd buy.If you dont usually walk around in any heels, I wouldnt suggest buying heels at all. Try and find some nice, fancy-looking flat shoes - there are loads of them around!------Which shoes should I wear for school?I'm sorry, I don't have any other suggestions but 3 is deff, out of the question, looks a little too older for you.

Why do you need to own so many pairs of shoes?LOL we don't need so many shoes, well at least i don't, but i guess its fun to try out different styles and experiment with them. And also it depends on your mood because if your feeling lazy...well you wouldn't wear high heels, but if you feel flirty you would wear heels :.
Is It Ok to Go on a Swim with Your Colleagues While on a Conference? [closed]
Is It Ok to Go on a Swim with Your Colleagues While on a Conference? [closed]
I want to try and be practical rather than judgemental.Is it generally inappropriate to go for a swim with coworkers (as well as other PhD students)?Generally it is not inappropriate, although it depends on which country you are in (more traditionalist or more liberal). In (almost?) all of Europe and in the US I would say it's inappropriate. But it's the specific circumstances rather than the general question that is the more delicate issue here.What to do if a person (like i.e.If you are the only woman - frankly, in your position, I would probably either not go at all (perhaps make arrangements with other people at the conference - a great excuse), or maybe I would join, but just dress in a shirt beach shorts. That is, unless I wanted to attract some sexual attention.Now, it's perfectly legitimate in my opinion for a woman to want to attract the attention of men in an out-of-the-office setting, and still expect to be treated professionally in the office; and as a male I would feel better if a female member of my group feels safe enough to do that; but - there is a minor risk of "spill-over" of sexualized perception back into the workplace. And you did mention you are worried about how this would affect your relations with your advisor. So it depends. If there is a small minority of women - I suggest you coordinate with them. Share your concern with one or two of them, and maybe they can share previous experience and assuage your fear, or verify it. Alternatively, you could come with a bathing suit underneath shorts and a shirt, then evaluate the dynamic on the beach, and if you feel comfortable/safe enough, dress down to your bathing suit. Remember nobody has to know you have that as an option, and you could still make some excuse regarding why you do not even have one.If there is a large fraction of women, things are easier: If some of them do not go, you can skip it too and not feel awkward about it. And if most of them go, then you will only be one of a larger contigent of women. And You can basically avoid your supervisor and stick with other women, so you are never in a more intimate one-on-one situation with him. There should be enough people (and enough women particularly) for this to be possible. Plus, you could still do the "bathing suit under shortsshirt" combination and delay the final decision until you are actually there.— — — — — —do other women feel this way. serious answers only?my husband also likes to watch, but i do not like him to touch me aft he finish watching! i warned him not to touch me whenever he finishing watching the porn movie! it's just like he....i do not really know how to say! but i really hate it !— — — — — —Is he cheating or am I paranoid?If he says he has "no sex drive" then he has not . And if he has not then he cannot cheat on you. Cheating is interesting only for those men who can f*ck 2 or 3 women simultaneously and easily. And usually the wife is that female who is easier and most comfortable to f*ck, and a fiasco does not count. Who cannot f*ck his wife will not have enough courage to try it with other women— — — — — —Females dress too provocatively and I am not comfortable with it.?Why do you care what other women wear??? Maybe you should not be looking at other women anyway perv— — — — — —Psychic describe how my future husband will behavior toward me, what about his personality ?He will KILL you! He will hate you for stopping him from screwing other women!— — — — — —Why do some women read fashion magazines?Fashion is popular because our clothes cover a good portion of our bodies, in cold weather, most. In other words, the clothes we wear is what we look like. This is not necessarily always important for beauty but it's always important for how people see you. If I were to have a job interview for example, I would try to dress as accordingly and impressive as possible. I would like to leave a good impression with my appearance as well as my personality. I would also like to feel that I look good -- when I am home alone, I still pay attention on what I wear. The main reason women read fashion magazines more than men is because women have more clothing options; it creates confusion to decide what to wear (therefor wish to get ideas) and competition with other women, also because women are being judged by their beauty/physical appearance more than men.I am a woman who had no interest in fashion until her mid-20s, yet I would occasionally get fashion magazines. A good fashion magazine offers very creative photography, interviews and product news. The photography was the most appealing part to me.P.S. The number of fashion magazines is actually pretty small compare to other genres. Some magazines some people know as "a fashion magazine" like Cosmopolitan, Marie Claire, In Style, Elle are regular/lifestyle magazines that target female readers and they give news and interviews about quite a lot of different subjects like fashion art, entertainment, health, sex, business, dating, food and more.
Whether Servo Motor Control Can Replace Stepper Motor Control, the Difference Between AC Servo Motor
Whether Servo Motor Control Can Replace Stepper Motor Control, the Difference Between AC Servo Motor
Servo motor refers to the engine that controls the operation of mechanical components in the servo system. It is an indirect speed change device of auxiliary motor. The servo motor can control the speed and position accuracy very accurately, and can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator, and has the characteristics of small electromechanical time constant, high linearity and starting voltage. It can convert the received electrical signal into angular displacement or angular speed output on the motor shaft. It is divided into DC and AC servo motors. Its main feature is that when the signal voltage is zero, there is no rotation, and the speed decreases at a uniform speed with the increase of torque.The structure of AC servo motor can be divided into two parts: stator and rotor. The structure of the stator is basically the same as that of the resolver, and two-phase windings with an electrical angle of 90 degrees are also placed in the stator core. One group is excitation winding and the other group is control winding. AC servo motor is a two-phase AC motor. When the AC servo motor is used, a constant excitation voltage UF is applied at both ends of the excitation winding and a control voltage UK is applied at both ends of the control winding. When voltage is applied to the stator winding, the servo motor will soon rotate. The current connected to the excitation winding and control winding generates a rotating magnetic field in the motor. The rotation of the rotating magnetic field determines the rotation of the motor. When the voltage applied to any winding is reversed, the direction of the rotating magnetic field and the direction of the motor will change.Stepping motor is an open-loop control motor that converts electric pulse signal into angular displacement or linear displacement. It is the main executive element in modern digital program control system and is widely used. In the case of non overload, the speed and stop position of the motor only depend on the frequency and number of pulses of the pulse signal, and are not affected by the load change. When the stepping driver receives a pulse signal, it drives the stepping motor to rotate a fixed angle in the set direction, called "step angle", and its rotation runs step by step at a fixed angle. The angular displacement can be controlled by controlling the number of pulses, so as to achieve the purpose of accurate positioning; At the same time, the speed and acceleration of motor rotation can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation.Stepper motor is a kind of induction motor. Its working principle is to use electronic circuit to supply power when DC is changed into component. Polyphase timing control current. When this current is used to supply power to stepper motor, stepper motor can work normally. The driver is time-sharing power supply for stepper motor. Polyphase timing controller.Although the stepper motor has been widely used, the stepper motor can not be used like the ordinary DC motor and AC motor. It must be composed of double ring pulse signal and power driving circuit before it can be used in the control system. Therefore, it is not easy to use stepping motor well. It involves many professional knowledge such as machinery, motor, electronics and computer. As an actuator, stepping motor is one of the key products of mechatronics, which is widely used in various automatic control systems. With the development of microelectronics and computer technology, the demand for stepping motor is increasing day by day, which is applied in various fields of national economy.Can servo motor control replace stepper motor controlIn specific applications, when the terminal load is stable, the action is simple and basically runs at low speed, the stepper motor with low cost and easy control is the most suitable; However, when the terminal load fluctuation range is large, the action is simple and basically runs at low speed, if the stepping motor is selected, it will face a series of troubles, because the stepping motor driven by square wave is difficult to eliminate vibration and noise, and will produce out of step or overshoot due to torque fluctuation. In fact, when the fluctuation range of terminal load is large, servo motor should be selected even if it is basically running at low speed, because after considering the factors such as efficiency improvement, energy saving, control accuracy improvement and system stability increase, it will be found that the selection of servo motor with higher price increases the comprehensive cost.What problems should be paid attention to when using servo motor instead of stepper motor?1. In order to ensure that the control system does not change much, the digital servo system should be selected, and the original pulse control mode can still be used;2. Due to the strong overload capacity of the servo motor, the rated torque of the servo motor can be determined by referring to 1 / 3 of the rated output torque of the original stepping motor;3. Because the rated speed of the servo motor is much higher than that of the stepping motor, it is best to add a reducer to make the servo motor work close to the rated speed. In this way, the motor with smaller power can also be selected to reduce the cost.At present, the servo motor tends to evolve step by step:1. Small size and high efficiency: the latest permanent magnet materials and optimized motor design are adopted, so that the small motor can also produce great torque. When the motor of the same model is matched with different drivers, the maximum output torque is different; When the same volume motor adopts different winding forms and different pole numbers, the output power is also different;2. Anti impact torque: the maximum torque can reach several times of the rated torque;3. Adopt high-performance magnetic materials with high magnetic energy product;4. Both motor and driver can be equipped with temperature monitor.Can servo motor control replace stepper motor control1. Stepper motor and servo motor are control motors, which are mainly used for precision positioning control. Especially servo motor, CNC system commonly used motor. Generally, the controller driver servo (stepping) motor coupling lead screw pair guide rail do not need a reducer, because the servo and stepping speed can adjust the speed in a large range according to the pulse frequency.2. Servo motor is closed-loop control, and stepping is generally open-loop control. Servo precision, more expensive than stepping.3. Servo and stepping are used for positioning. For example, when moving at a certain speed from the origin to 10mm and then to 25mm, stop returning.4. Both are special motors, which can accurately control the speed. However, the principle of speed control is different: the servo motor is closed-loop control (completed through encoder feedback, etc.), that is, the speed of the motor will be measured in real time; The stepper motor is open-loop control. When a pulse is input, the stepper motor will turn a fixed angle, but the speed will not be measured.Difference between AC servo motor and stepping motorThe main difference between AC servo motor and stepper motor is that the stepper motor is open-loop (without encoder) control. If the load is too large or there is jamming, the step will be lost. The servo motor is closed-loop control (with encoder), there will be no step loss, and the stability and accuracy are higher.Stepping motor is a discrete motion device, which is essentially related to modern digital control technology. In the current domestic digital control system, stepping motor is widely used. With the emergence of all digital AC servo system, AC servo motor is more and more used in digital control system. In order to adapt to the development trend of digital control, stepping motor or all digital AC servo motor are mostly used as executive motor in motion control system. Although they are similar in control mode (pulse train and direction signal), there are great differences in service performance and application occasions. The performance of the two is compared.1、 Different control accuracyThe step angle of two-phase hybrid stepping motor is generally 3.6 ° and 1.8 °, and that of five phase hybrid stepping motor is generally 0.72 ° and 0.36 °. There are also some high-performance stepper motors with smaller step angles. For example, a stepping motor for slow wire walking machine tool produced by Sitong company has a step angle of 0.09 °; The step angle of the three-phase hybrid stepping motor produced by Berger Lahr in Germany can be set to 1.8 °, 0.9 °, 0.72 °, 0.36 °, 0.18 °, 0.09 °, 0.072 ° and 0.036 ° through the dial switch, which is compatible with the step angle of two-phase and five phase hybrid stepping motors.The control accuracy of the AC servo motor is guaranteed by the rotary encoder at the rear end of the motor shaft. Taking Panasonic all digital AC servo motor as an example, for the motor with standard 2500 line encoder, because the frequency quadrupling technology is adopted in the driver, the pulse equivalent is 360 ° / 10000 = 0.036 °. For the motor with 17 bit encoder, the motor rotates once every 217 = 131072 pulses received by the driver, that is, the pulse equivalent is 360 ° / 131072 = 9.89 seconds. Is 1 / 655 of the pulse equivalent of a stepping motor with a step angle of 1.8 °.2、 Different low frequency characteristicsStepper motor is prone to low-frequency vibration at low speed. The vibration frequency is related to the load condition and driver performance. It is generally considered that the vibration frequency is half of the no-load take-off frequency of the motor. This low-frequency vibration phenomenon determined by the working principle of stepping motor is very unfavorable to the normal operation of the machine. When the stepping motor works at low speed, damping technology should generally be used to overcome the phenomenon of low-frequency vibration, such as adding damper on the motor or subdivision technology on the driver.The AC servo motor runs very smoothly and will not vibrate even at low speed. The AC servo system has resonance suppression function, which can cover the lack of mechanical rigidity, and the system has frequency analysis function (FFT), which can detect the mechanical resonance point and facilitate the system adjustment.3、 Different torque frequency characteristicsThe output torque of stepping motor decreases with the increase of speed, and will decrease sharply at higher speed, so its maximum working speed is generally 300 600 rpm. AC servo motor is constant torque output, that is, it can output rated torque within its rated speed (generally 2000rpm or 3000rpm), and constant power output above rated speed.4、 Different overload capacityStepper motors generally do not have overload capacity. AC servo motor has strong overload capacity. Taking Panasonic AC servo system as an example, it has the ability of speed overload and torque overload. Its maximum torque is three times of the rated torque, which can be used to overcome the inertia torque of inertia load at the moment of starting. Because the stepping motor does not have this overload capacity, in order to overcome this inertia torque, it is often necessary to select the motor with large torque, and the machine does not need so large torque during normal operation, so the phenomenon of torque waste appears.5、 Different operation performanceThe control of stepping motor is open-loop control. If the starting frequency is too high or the load is too large, it is easy to lose step or stall. If the speed is too high when stopping, it is easy to overshoot. Therefore, in order to ensure its control accuracy, the problems of speed increase and speed decrease should be handled well. The AC servo drive system is a closed-loop control. The driver can directly sample the feedback signal of the motor encoder. It forms a position loop and a speed loop. Generally, there will be no step loss or overshoot of the stepping motor, and the control performance is more reliable.6、 Different speed response performanceIt takes 200 400 milliseconds for the stepping motor to accelerate from static to working speed (generally hundreds of revolutions per minute). The acceleration performance of AC servo system is good. Taking Panasonic MSMA 400W AC servo motor as an example, it takes only a few milliseconds to accelerate from static to its rated speed of 3000rpm, which can be used in control occasions requiring rapid start and stop.in summary

I've used pledge multi-surface on a cheap old jacket but, would only recommend to try it on a inconspicuous area first!4. Where can i buy a similar guy leather jacket like this?till you come upon a leather-based professional, no person could have the potential to tell no depend if that's real leather-based or fake. real leather-based is extremely expensive and it will final you an exceedingly long term, so specific that's a important investment...fake leather-based wo not final as long and you will see that it's going to start to "shed" and disintegrate from consistent placed on. ..in spite of the indisputable fact that it's going to final some years or so5. Black leather jacket is leaving black specs on me.?You can have it professionally cleaned, and that should get rid of the problem, but that will cost more than the jacket. Where are the specks coming from? If it is coming from the surface of the leather, it's probably dry rotted or water damaged, and will be difficult to fix. If it's from the interior surface of the leather, where it's rough and nubbly, it's probably just from being stored and will stop shedding soon. you can try wiping the entire outer surface down with leather cleaner or armor-all, and wiping the inside down with a damp cloth. If those are the surfaces the flecks are coming from that should help. You can also put it in the dryer on the lowest heat setting and letting it tumble with a couple old sneakers for an hour or so, to try to re-break-in the leather and shake the rest of the specks out. Good luck! EDIT: Ok, if it is faux, there is no way to save it. That's why you will usually notice cracking and flaking around the collar and cuffs first. Using the brush was a good idea, and you can still try wiping it down/tumbling it in the dryer. Even so, there's no way to stop the deterioration process. Sorry!6. how can i get the wrinkles off a leather jacket?Ha! Ha!7. POLL: SHOULD I BUY THIS leather jacket?Are you auditioning to be Wolverine?8.

How to wash or clean a leather jacket?do not wash. dry cloth and spray with the stuff u use to clean leather sofa's/chairs!12. how do i clean my leather jacket?Purchase a special spray, or just rinse it down with water. I have a leather coat, but I try to keep it away from salt and water. Leather is meant to age and crack!13. Would I look good in a leather jacket (pics included)?Ok Brother, you need a serious self confidence boost. You look fine, and if you want a leather jacket get one. I think it would look pretty good on you but that's because I like the jacket. Really you need to pick your style and go with it. Be your own man. I've had self confidence issues for a long time myself and I've fought through them. I've seen your other posts on here and always hesitated to answer. You do not look 30, you do not look fat, you look fine. Just be happy with yourself. Now get the leather jacket, by a motorcycle and go kick some ***. You are a man and should be proud of the man you are.
I Need a New Style for Highschool.?
I Need a New Style for Highschool.?
Dye your hair black and paint your face white. Gothic is the most unique and awesome look you could have1. whats the new style for men?Hawaii is too cool for trends ... or rather too hot. Stick to the board shorts or you will get beat up! :P2. Want to have new style for college?Best answers to those questions are what do you feel comfortable in ? Take a walk around the malls/shopping centres look at what the other boys your age are wearing, casually, sports wise. and then decide on what you want your look to be.. Do not dress in plaid pants lol.. Honestly the thing is not to look as you have tried to hard ok.3. I want to dye my hair a new colour and get a new stylemy hair is all organic in no way been dyed or permed and that i variety it myself it incredibly is a dark brown curly and wavy and is going right down to easily under the middle of my returned i placed on my bangs short so i will see and feather in simple terms the ideal of my hair. I definitely have continually enjoyed my hair I definitely have sufficient different flaws yet my hair has in no way been one among them, i plan on protecting it this type for as long as i will till it starts off to show gray then i will probable dye it because it barely sufficient to conceal the grey I definitely have been thinking approximately feathering the full front of my hair yet i think of i did as quickly as whilst i replace into youthful and then could not anticipate it to advance returned out so i probable wo not , i think of alot human beings ladies detect a solid coiffure that we adore and seems to bypass superb with our personalities and then its in simple terms complicated to alter what is all of us be attentive to is risk-free. besides satisfied holidays4. Leather jacket with pajama pants? OMG is that a new style for ladies?no eww. that's sooooo trashy. NOT stylish, at all5. What is the new style for basketball socks?? ankle socks or high socks?? i am white by the way. ok thanks!?Im not trying to be racist here but for a white guy, ankle socks. High socks are good on black players like A.I6. I definitely need a new style?we need a little more detail.. like what you look like, what you usually wear, and some ideas you have we cant really answer when we have no info7. 1 thing i hate more than steryotypes is people trying to not fit in to be cool .. cmon. be u not the new style?Fashion is all about identity. People dress in a style that best defines who they think they are. There are barely any people who can claim they have an original look. Isabella Blow and Alexander Mcqueen were some of the few who had a very original look. Lady Gaga is not even an original herself. Most her clothes are costumes, and the parts of her wardrobe that were not costumes were actually just super chic outfits. Every fashionista has dressed like Lady gaga a few times in their life. Lady Gaga's everyday wear had a lot of references to other fashionable people and designers. Her "Gaga" hat made by Philip Treacy was based off of Isabella Blow's "Blow" hat. She also most likely got her clothes from designer boutiques or from the runway. I;ve seen her in pieces from Alexander McQueen, Thierry Mugler, and even Chanel. Baggy jeans, wife beaters, and jordans just look gangster and ghetto. Who really would want to identify with that subculture? It's classless and sad.8. Im looking for a new style of jeans?well i think lei is a good thing, but im a girl so i dont know wat guyz egzactely wear...9. i have thick hair thats kinda wavy n im lookin for a new style cuz im sick of the same ponytail?I have thick wavy hair too!! So does my best friend. She got her hair relaxed... not to expensive for how long it lasts and how good it makes your hair look! :) My hair is in a ponytail almost everyday too lol I am thinking about getting mine relaxed... it just pretty much makes your hair smoother and easier to do whatever with... straighten, curl. A cute hairstyle i like to try... do not know if it will work because i do not know how long your hair is but here is how you do it.... bring 1/2 your hair up but DON'T use a brush when you pull it back just go by your ears and pull it back from there. let it look like its bumpy and not perfect or even or w/e. then take a pony tail and wrap it around the pony tail once... the 2nd time only due it 1/2 way and then wrap it around again so that it kinda makes a messed up/upside down bun. then with the hair that is down... curl it or straighten it. another cute way that i kinda just do my hair on mornings that i am running late... if my hair is straight then i kinda do a simple messy french braid in the back. you do not start at the top... just above where your hair is on the back of your hair (you do not really have to french braid) just start there with a regular braid then braid til the end.. if your hair is long enough... do it at kinda an angle so you can let it hang over one shoulder... do it loose cause then its really cute!! feel free to e-mail me if you have ANY questions Good Luck!!!!! ____________________EDIT_______________________ i forgot to mention this... but you should get your hair cut to your shoulders or a lil longer and get layers. That way... its easier to deal with, thinner and you can still put it in a cute ponytail when you want to :). That is how my hair is now! I just do not like taking the time before school to do my hair all cute and stuff. And i play golf so its always in a ponytail for that. Anyway.... just a cute haircut idea. Good luck
Were Probably Undervaluing Healthy Lakes and Rivers
Were Probably Undervaluing Healthy Lakes and Rivers
For sale: Pristine lake. Price negotiable.Most U.S. government attempts to quantify the costs and benefits of protecting the country’s bodies of water are likely undervaluing healthy lakes and rivers, researchers argue in a new studyThat’s because some clean water benefits get left out of the analyses, sometimes because these benefits are difficult to pin numbers on. As a result, the apparent value of many environmental regulations is probably discounted.The study, published online October 8 in the , surveyed 20 government reports . Most of these laws have been enacted since 2000, when cost-benefit analyses became a requirement. Analysis of a measure for restricting river pollution, for example, might find that it increases costs for factories using that river for wastewater disposal, but boosts tourism revenues by drawing more kayakers and swimmers.Only two studies out of 20 showed the economic benefits of these laws exceeding the costs. That’s uncommon among analyses of environmental regulations, says study coauthor David Keiser, an environmental economist at Iowa State University in Ames. Usually, the benefits exceed the costs.So why does water pollution regulation seem, on paper at least, like such a losing propositionKeiser has an explanation: Summing up the monetary benefits of environmental policies is really hard. Many of these benefits are intangible and don’t have clear market values. So deciding which benefits to count, and how to count them, can make a big difference in the results.Many analyses assume water will be filtered for drinking, Keiser says, so they don’t count (). That’s different from air pollution cost-benefit studies, which generally do include the health benefits of cleaner air by factoring in data tracking things like doctor’s visits or drug prescriptions. That could explain why Clean Air Act rules tend to get more favorable reviews, Keiser says — human health accounts for about 95 percent of the measured benefits of air quality regulations.“You can avoid a lake with heavy, thick, toxic algal blooms,” Keiser says. “If you walk outside and have very polluted air, it's harder to avoid.”But even if people can avoid an algae-choked lake, they still pay a price for that pollution, says environmental scientist Thomas Bridgeman, director of the Lake Erie Center at the University of Toledo in Ohio.Communities that pull drinking water from a lake filled with toxic blooms of algae or cyanobacteria spend more to make the water safe to drink. Bridgeman’s seen it firsthand: In 2014, Lake Erie’s cyanobacteria blooms from phosphorus runoff shut down Toledo’s water supply for two days and forced the city to spend $500 million on water treatment upgrades.Most of the studies surveyed by Keiser and his team were missing other kinds of benefits, too. The reports usually left out the value of eliminating certain toxic and nonconventional pollutants — molecules such as , or BPA, and perfluorooctanoic acid, or PFOA (). In high quantities, these compounds, which are used to make some plastics and nonstick coatings, can cause harm to humans and wildlife. Many studies also didn’t include discussion of how the quality of surface waters can affect groundwater, which is a major source of drinking water for many people.A lack of data on water quality may also limit studies, Keiser’s team suggests. While there’s a national database tracking daily local air pollution levels, the data from various water quality monitoring programs aren’t centralized. That makes gathering and evaluating trends in water quality harder.Plus, there are the intangibles — the value of aquatic species that are essential to the food chain, for example.“Some things are just inherently difficult to put a dollar [value] on,” says Robin Craig, an environmental law professor at the University of Utah in Salt Lake City. “What is it worth to have a healthy native ecosystem... That's where it can get very subjective very fast.”That subjectivity can allow agencies to analyze policies in ways that suit their own political agendas, says Matthew Kotchen, an environmental economist at Yale University. An example: the wildly different assessments by the Obama and Trump administrations of the value gained from the , also known as the Waters of the United States rule.The rule, passed under President Barack Obama, clarified the definition of waters protected under the 1972 Clean Water Act to include tributaries and wetlands connected to larger bodies of water. The Environmental Protection Agency estimated in 2015 that the rule would result in yearly economic benefits ranging from $300 million to $600 million, edging out the predicted annual costs of $200 million to $500 million. But in 2017, Trump’s EPA reanalyzed the rule and proposed rolling it back, saying that the agency had now calculated just $30 million to $70 million in annual benefits.The difference in the conclusions came down to the consideration of wetlands: The 2015 analysis found that protecting wetlands, such as marshes and bogs that purify water, tallied up to $500 million in annual benefits. The Trump administration’s EPA, however, left wetlands out of the calculation entirely, says Kotchen, who in in 2017.Currently, the rule has gone into effect in 26 states, but is still tied up in legal challenges.It’s an example of how methodology — and what counts as a benefit — can have a huge impact on the apparent value of environmental policies and laws.The squishiness in analyzing environmental benefits underlies many of the Trump administration’s proposed rollbacks of Obama-era environmental legislation, not just ones about water pollution, Kotchen says. There are guidelines for how such cost-benefit analyses should be carried out, he says, but there’s still room for researchers or government agencies to choose what to include or exclude.In June, the EPA, then under the leadership of Scott Pruitt, proposed revising the way the agency does cost-benefit analyses to no longer include so-called indirect benefits. For example, in evaluating policies to reduce carbon dioxide emissions, the agency would ignore the fact that those measures also reduce other harmful air pollutants. The move would, overall, make environmental policies look less beneficial.These sharp contrasts in how presidential administrations approach environmental impact studies are not unprecedented, says Craig, the environmental law professor. “Pretty much every time we change presidents, the priorities for how to weigh those different elements change.”
Assume Two Objects Are Travelling Less Than Half of the Speed of Light to Opposite Directions and Ob
Assume Two Objects Are Travelling Less Than Half of the Speed of Light to Opposite Directions and Ob
Perhaps you can answer it yourself by looking at Velocity-addition formula - WikipediaThere are two different addition formulas: "Galilean relativity" and "Special relativity".You seem to be assuming Gailean relativity - where velocities simply add, and also that the speed of light is relative to the emitter. Both of those assumptions are false, you need to read the "Special relativity" section and accept that both objects will measure an unchanged velocity of light. Each object will see the other object red-shifted, not vanishing— — — — — —Is there a new discovery that the speed of darkness is faster then the speed of light?light and darkness form a dichotomy pair... one is dynamic, the other static. Hence the characteristics of a static are opposite to those of a dynamic. Furthermore if darkness showed any indication of being dymanic, scientists would have reocnised this long ago since it is such a fundamental issue to the structure and function of the universe.— — — — — —Did Einstein consider the speed of light as a universal constant?Yes.He believed that speed of light is constant forever...Even though u make a race with light to achieve light speed and make to going constant of u and light,the light would definetely have 3,00,000km/s with compared to u also even though u travelling with nearly equal to speed of light..Because the light have that behavior....note: achieving of light speed is not make so hard to believe in some thousand years later..But changing the speed of light is impossible with compared to any reference....— — — — — —What speed does current travel through wires?The electrons in a wire move very slowly. centimeters per minute. But the electric current that gets passed down the wire moves at the speed of light.— — — — — —Is the speed of light the fastes form of travel?The speed of light is a measure of.um.SPEED. Not a vehicle— — — — — —How many times faster is the speed of sound that the speed of light?I think this question deserves a direct answer.The speed of sound in air varies with the air density and humidity, but a typical value is 343 meters per second. If you're not familiar with the metric system, a meters is about 39 inches, or a little more than one yard. The speed of light is 300 million meters per second. A more precise value is 299.8 million meters per second.If we divide, we get roughly 1.14 x 10^-6. So the speed of light is about 1/0.00000114 ≈ 877,193 times 'faster" than sound. Another way to say this is that the speed of sound is about one millionth the speed of light. Or that light is about a million times faster than sound.And yes, most people would just say sound was 'slower" than light. But you can multiple by a tiny fraction instead, if you like. Whatever math gives the right answer is fine. Some ways of doing the math seem more clumsy than others, but that's just a subjective judgment— — — — — —Why is the speed of light the speed it is?I have written about this.The speed of light is what it is, because the characteristics of the vacuum.The vacuum permittivity, "εo", is a physical constant which represents the capability of a vacuum to permit electric fields. It is also connected to the energy stored within an electric field and capacitance. The vacuum permeability, "μo", is derived from production of a magnetic field by an electric current in a vacuum.But this is a little hard to understand. Just understand that in any medium, electromagnetism behaves is a way that depends on the characteristics of the medium. In a vacuum, some characteristics (which determine the speed of light and all electromagnetic phenomena) have some residual influence.— — — — — —TrackPad Speed and Mouse Speed - Resets to slow every timeI had this problem but I had smoothmouse installed.

If not, is it due to the Higgs field?No and no. It is due to the limitations on geometry and causality.But see discussion: Does the speed of light vary in noninertial frames?I am concentrating on the misunderstandings evident in the question.The speed of light in GR is not related to the Higgs … GR does not know about Higgs, as Higgs belongs to a completely different theory.

Anyone Has a New Vw Beetle and Had Their Signal Lights Stop Working?
Anyone Has a New Vw Beetle and Had Their Signal Lights Stop Working?
Typical VW feature. I always see taillight issues with VW and VW related cars (Audi, Porsche, Bugatti, Lambo, etc...)1. How to find a short in my signal lights?Get youself a multi task voltmeter and a bunch of mini-fuses from your auto supply store. Mini-fuses are generally for motorcycles they look like auto but half the size and double the cost. 10 amps is Red and likely what you will need. Get a dozen or so to do test. Voltmeter costs about 10-15 bucks. Pop seat and or side panels to locate the main wire harness a thick bundle of wires wrapped in black protective weather-proofing that is likely beneath the seat near the battery. This harness usually has a seperated split of a smaller harness of 4-8 wires. These coloured wires have seperatable connections that control electricity to turn signals, brake and tail light, hot wired licence plate, and auxillary after market accesories. These are male / female connections and are housed in a wet proof sheathing. They have all colours. Consult your manual for the wire schematics and find the corresponding colours to circuit. The 'male' is likely the power source so with your voltmeter and the bike key turned on (or engine running) take a fresh mini-fuse insert into blown fuse slot. Now try different combinations with turn signals, brake levers pulled, use the horn, etc until you blow the fuse on purpose. you are narrowing the possible circumstances to find which combo or single electrical need causes the circuit to be shorted. Keep in mind the wire schematics will take all of the guess work out of the function of a wire. The wire can have 2 uses so study the wire plan. These 'hot' circuits mean they do not get switched off while the bike is running. The licence plate circuit is one example. Alternating circuits (left light/right light/brake light) will have one different wire colour to switch on its need and the other attached to a hot circuit. Your volt meter again is usefull to determine live circuits as long as you measure on the power feed side of the main wire harness. It takes a bit of detective work but once you get it you will have the benefits of knowing the causes and fixes if you break down on the road. When that happens you will only need extra min-fuses and tape to fix those problems.2. Why are my signal lights flashing as if i hit the emergency light button by themselves with no key?you probably put in a wrong fuse3. Im my 1992 lexus, all Signal lights work, except for the front passenger side.....?Forget the wiring, if a new bulb did not fix the problem, possibly the bulb socket is corroded or rusty, check that4. Can i have blue led front signal lights or are they illegal?Tough beans, amber is the colour required by FEDERAL law5. my signal lights don't work in my 81 cutlass?Use a 12 volt test light to see if there's power to the bulb's socket. If you have power there, then you have a bad ground. When you say 'signal lights' I assume you mean the turn signals. Have you checked the flasher module? (that little round can that makes the ticking noise when the light blinks on and off) It could be bad6. need help on troubleshooting my right turn signal lights!?Check out the front turn light. Usually when one of the bulbs are blown the green arrow on the dash will light but not blink meaning one of the bulbs are bad7. Fiber between two sites - no signal lightsFrom the J9150D datasheet you linked, the max transmission distance over an OM1 fiber is 33m.Thus you need other transceivers, or to change the fiber8. are blue LED signal lights for my side window mirrow legal in california?Blue Led Turn Signal Lights9. eye does not produce aqueos fluid What can be done?Hi Ree I have a few successful testimonials from the website I purchase my herbs from. Testimonials 1.Cataracts Disappear: A lady with cataracts had been blind for a number of years, and yet in nine days she had her full sight back. This astounded Dr. Christopher, for it to have happened so fast. Other people go on the program for as long as three years, and though they then can see better than before, they have not been completely healed. Others clear in a matter of months--it varies with the individual. 2.Dry Eyes and Cataracts: I have had bad eye trouble for two or three years. The beginning of cataracts on both eyes, I had the jel break in both eyes--at that time my eyes were so terribly dry that I would have to lift the eyelids off my eyes in the morning with my fingers. My vision was getting real bad. I have been taking exercises for my eyes, using the eye wash and taking the Eye Wash Formula. My eyes are much, much improved. I am positive that the cataracts will be completely dissolved. Thank God for you and the wonderful work you are doing. 3.Cataracts, Glaucoma and Bad Vision: I was diagnosed as having a fast growing cataract in my right eye and a build-up of pressure in both eyes causing glaucoma. I then found in Newsletter #19 all about Herbal Eyewash [Herbal Eyebright] and capsules, which I ordered and received on November 4. I immediately started using both three times a day--with marvelous results. Within three days I could see through my new glasses, bi-focals. I had not been able to since I got the new glasses which had stronger vision for distance and weaker bi-focals. So I had to change to my old glasses for my bookkeeping work and the new ones for driving. Suddenly I realized I forgot to change them when I sat down at my desk at my office (because I was seeing figures perfectly, I had forgotten I had them on). Then within two weeks I suddenly realized I could see much farther with the bad eye with the cataract, when I could not see with it at all before. All along small pieces of mucus is coming out of my eyes many times daily. Before using eyewash, I could not stand driving after dark as the car headlights, tail lights, signal lights and street lights all had huge halos around them of flashing red, yellow and green, very scary. So I had to be very careful not to leave my office so I would get home after dark. Now the halos have disappeared and I see only a tail on each light which I think looks like only a small part of a halo and I take that to mean my eyes are improving. I am very happy with continuing improvement and have full confidence that my cataract and glaucoma will be cured. I have started two friends using it too, and they both tell me they are having good improvements too. Neither have cataracts or glaucoma, but they do have weak eyes and wear glasses. 4.Vision Improves: I started the Eyebright formula treatment... TWO WEEKS AGO. My vision has improved immensely, needless to say my first few days of treatment were rather hectic, but as I read the doctor's answers to questions in the Healthview letters, I was encouraged to go on. I bought the herbal eye-wash powder so it was necessary for me to strain it as I made it each morning. In preparation I had bought a box of filter drip coffee filters rather than using the gauze. When I poured the tea through the filter, it plugged up almost immediately. So the next morning, I put a teaspoon of the powdered tea in the filter, tied it shut with a twistum, thus making a tea bag. Bring the cup of distilled water to a boil with the tea bag in it. Let it stand until it cools. Works beautiful. No fuss no muss. Someone else has probably already thought of this method. I will write you more as it progresses. Eyebright Formula has helped me and a few friends of mine. I would give it a try. Best of health to you. Cheers
Homework Help!! Have You Ever Experimented with Sulfuric Acid??
Homework Help!! Have You Ever Experimented with Sulfuric Acid??
Sulfuric acid on the metal item will react strongly producing hydrogen and a sulfide of the metal. In time just eating it away. On paper it will react with the moisture in the paper producing heat which will blacken or char the paper disintegrating it eventually. The same on meat the reaction with the water will produce heat and burn it, as you will find out if you're not careful and get any on you. On the plastic item it probably won't react but there is a lot of differences in plastics so you should be careful. On the second part of your question, let me start by saying that you should NEVER add water to the acid it would splatter and diffuse acid vapors into the air as well as get very hot. To dilute sulfuric acid add the acid to the water. On your plastic item adding water to the acid would probably melt the plastic. After the initial heat reaction on all the items the diluted acid would have less reaction on each item• Suggested ReadingWould you recommend getting one?First of all you have to make sure that the weather there is not too hot for the chinchilla. Their fur is very dense. I always want one, but I live in tropical...very sad...They are very fragile too, they can break their bone when fall from a high place ( unlike hamsters or rats: they can survive from a fall ).I don't know if they smell, but it could be true too!!!They also make a lot of mess, my friend told me if you want it to run free in a room, you will pay the price for fixing the wall.Also the sand bath for hamsters will not work for chinchillas. There are chinchilla dusts you can buy from pet shops or go search on amazon.com, but better you buy from pet shop because you can actually see the dust or compare for quality.This is very cute, if I get one chinchilla I WILL buy one of this so maybe you want to buy one too ; ) I don't know much about them, but chinchillas are beautiful and cute.------Your fav hard rock songs?Watchtower by Abigail WilliamsWhoa!

In earlier times pure lead sticks used to write on paper. (if you rub a piece of lead on paper it will make a mark same as graphite) Therefore pencils with a graphite stick in middle is still called lead pencil.Lead (pronounced /ld/) is a main-group element with symbol Pb (Latin: plumbum) and atomic number 82. Lead is a soft, malleable poor metal, also considered to be one of the heavy metals. Lead has a bluish-white color when freshly cut, but tarnishes to a dull grayish color when exposed to air. It has a shiny chrome-silver luster when melted into a liquid.Lead is used in building construction, lead-acid batteries, bullets and shot, weights, and is part of solder, pewter, fusible alloys and radiation shields. Lead has the highest atomic number of all stable elements, although the next element, bismuth, has a half-life so long (longer than the estimated age of the universe) it can be considered stable. Like mercury, another heavy metal, lead is a potent neurotoxin that accumulates in soft tissues and bone over time. Lead poisoning was documented in ancient Rome, Greece, and China.------Will my guitar go out of tune often even if I don't use the whammy bar?Hello there,A tremolo bridge will put strain on the factors that cause or avoid tuning instability. It amplifies other problems.The number one problem with tuning instability is improperly installed strings. Learn to use the lock down method. Make sure you keep a good tension on the string as you wind it and that you keep the wraps going downward. Do not allow the wraps to go over each other. Do not have too many wraps.Next, make sure you lube the points of frictions. Where the string rubs against the guitar, the string must be able to slide freely and not to hang up. Lube with graphite (pencil lead is fine) the slots of the nut, the saddles and the string trees.Lastly, learn how to set up your tremolo properly. A properly adjusted tremolo will return to the in-tune position after use. The strings pull on the bridge. To counter balance the pull of the strings, the tremolo has springs that pull in the opposite direction. The pull of the springs should be equal to the pull of the strings.If you really do not plan to use the tremolo, you can block it. However, you still need to install strings properly and lube the points of friction.Talk to you later,Norm------How to convince my dad to get me a new backpack for school???!?Well! As for me, when I want something from my dad or want him to do something for me I follow two proceduces which are (1) As a student, my father love my intelligency. So at this time I need something from him I work my assignment very close to him and at this time, I don't let anything distract me from knowing that he have put a little or more interest in what am doing and at that time am through with my work, I kindly ask him want I want from him and believe me, he will promise to do it almost immedately. (2) My father is that person that love seing me at home. So, at this time I need something to be done for me, I will keep myself in the yard so that he can be able to seen me. Maybe that day, he wish to send me on an erant, I pomptly finishe them and this alway impress him. And toward the end of the day, I ask him that I need and he will promise to do and will do it almost immedately. I believe if you try those poceduces, you will convince your own dada to buy you the new backpack. That of where you can get a new backpack I don't have any idear.

The magnetic field will need to be strong as there is only one turn in the armature of this electric motor. The magnetic field can be permanent or electromagnetic. The other thing you can do is minimize friction by placing it in water or on something that floats so it may be able to rotate freely. I will try this tomorrow when I finish work, my bedtime now. If it works will add an edit to this answer.PS Older pencils in Australia used to be referred to as LEAD pencils and lead is a conductor as well as carbon. I'm sure for health reasons they no longer contain Lead so for those who choose to chew their pencil they now have to obtain this part of their diet from another source. One more thing Graphite it conducts and is used in pencils as well. Don't go fishing with your Graphite rod when there is lightening about!------Do I need therapy, I'm 13 and scared, please help?It sounds to me like you need to make big changes in your life. You're feeling unhappy and scared and it may partly be due to hormones and partly to the lifestyle you're leading. If you have a pastor at your local church or someone mature that you can talk to, I would highly recommend it as it is not normal for you to cut yourself or have anorexia. You're not weird and you're not crazy. You are a beautiful and sensitive young lady who enjoys writing and music. You're just different from your family so stop trying to be perfect. It's making you very unhappy. None of us are perfect otherwise we would not be here on earth.My suggestion is to also keep a diary and write down your thoughts, feelings and emotions especially before you feel like cutting yourself. As you do you will notice what happens prior to your wanting to cut yourself or to binge/starve. Lastly, my next suggestion is to start volunteering your time helping others less fortunate than you - go to an old folks home and offer to help, go to a local animal shelter or join some organization where you can volunteer. This will stop you feeling unhappy about yourself, you'll make new friends and with old folks, you'll enjoy learning from their experiences.------How do pencil erasers work?I've always assumed the eraser was a porous material. it pulls off the graphite because graphite is a gritty material (kinda like solidified powder).Some erasers on cheap pencils are just plastic and poor quality, which wont take the graphite off quite as easily. Good artist's erasers vary but do the same thing. Some erasers are a pliable sticky material that will pull off the graphite powder, others (white plastic erasers or pink erasers) pull the powder away while cleaning it off themselves by leaving that residue.hard erasers can tear the paper because paper is just filaments stuck together. if you erase too hard or too often, it will tear off those filaments, leaving a "hole" in your paper. That hole makes the paper have a tendency to rip, which is why I'd suggest investing in a good art gum eraser or a white plastic eraser! Even if you aren't doing art, it is nice to have a clean sheet of paper to work on.That's what I always thought anyway!! Its good to know people are asking random questions!!
What Does It Mean When You Dream of Getting Married but Forgot Everything but Your Wedding Dress? No
What Does It Mean When You Dream of Getting Married but Forgot Everything but Your Wedding Dress? No
This dream is a dream of preparation and unpreparedness. If you are not getting married in your waking life then this dream is showing you how there are essential requirements in your life that you are forgetting.We are married to life. We owe it to ourselves to be the best we can be. Often times we show up for the day dressed to impress but we are far from being ready.Accessories of wedding attire are essential as they make the garment. Without accessories in life we are bringing less than of who we are to the environment we have chosen for ourselves. Everything in dreams is symbolic and I invite you to consider those missing accessories: earrings accentuate our ears. The things that we hear and allow our minds to ruminate in. Makeup accentuates the face: eyes to see and lips to speak. A necklace accentuates our voice that is close to our hearts- do you chose your words wisely from the heart and speak love to you, to others and into life daily? Rings and bracelets accentuate your hands which represent the things you do from the things you allow into your header and mind. Having no shoes may signify that you are not yet ready to venture out into the territory that you wish to walk in. Having firm footing is essential as shoes protect your feet from rocky ground and hazards along your journey. You are on your way, however your dream maybe telling you to take a bit of time to properly equip yourself and prepare for the journey ahead. You may already find yourself in a situation that is troublesome and you are feeling unprepared for. That's okay. Your dream is challenging you to take care of yourself. Put yourself first too as now is not the time to be neglecting you.• Related QuestionsHow did Princess Eugenie's wedding evening dress compare to Kate Middleton's and Meghan Markle's?Do you mean wedding dresses? I've compared both.In my opinion:First placeCatherine, Duchess of CambridgeStunning dress, with beautiful lace detail. A timeless piece, showing off her amazing figure. Pinched in at the waist and shows off her shoulders and neck beautifully. Beautiful bodice, and lace combination. Lovely lower dress line. A petite tiara to finish the stunning look.Second placePrincess EugenieBeautifully shaped at the back. Pinched in at the waist. Lovely V shape detail upper back and beautifully bunched below the waist. Elegant train and beautiful emerald tiara. Not too keen on the shoulder collar design at the front. Third placeMeghan, Duchess of SussexNo shape, not pinched in at the waist or anywhere else. The shoulder line was wide, yet it looked tight around arms and armpits. The dress showed no trace of her figure. It looks likes a potato sack. Just in beautiful material. No special details what so ever, bar the embroidery on the train. Wedding Evening DressesFirst placeCatherine wore a custom-made lace ivory dress by Alexander McQueen made by designer Sarah Burton, featuring a sweetheart neckline and paired with a white angora bolero cardigan. The designer had also designed the Duchess of Cambridge's iconic ivory satin and lace wedding dress. Again the cut was superb. beautifully pinched in at the waist, stunning bodice with a perfect dress line. Lovely detail around the waist, simple but stunning. Both dresses Catherine chose, really showed off her fantastic figure.Second placeEugenie wore a long sleeve, blush silk Zac Posen gown with a built-in cape. I absolutely love this dress, the colour is yummy and the pleat details are stunning. I don't know if I would have had the cape added, but still beautiful. Pinched waist, exquisite detail.Third placeMeghan wore a white, high neck Stella McCartney silk crepe halter gown design. This in my opinion, was much nicer than her wedding dress, but still didn't shown off her figure and wasn't very original. Beautiful flow at the bottom of the dress, no pinched waist or bodice hugging.-BA Fashion DesignHow did Princess Eugenie's wedding evening dress compare to Kate Middleton's and Meghan Markle's?How did Princess Eugenie's Wedding Evening Dress Compare to Kate Middleton's and Meghan Markle's?.------Where can I find a cotton wedding dress in Philadelphia?Where can I find a cotton wedding dress in Philadelphia?Any dress worn for a wedding is a wedding dress. If you want an all cotton dress in white or another color for the big day, you will probably have the least frustrating experience by hiring someone who does custom sewing of gowns. I don't think that you will have much luck in finding a ready made cotton bridal gown in the wide variety of styles that are made of silks, satins and at the lower price points, polyester. Are you looking for a casual but modern silhouette in a cotton dress, a vintage dress like the day dresses from the 1950s with full skirts that use crinoline to create volume or something else entirely? Know what you want before you have the consultation. Bring inspirational photos or even a commercial pattern if you find one in the correct style or close to it. Be careful to select any pattern size by using your measurements and not your ready-to-wear clothing size. There are specialists who only sew wedding dresses, pageant gowns and quinceanera dresses. Those are dresses that can require numerous layers and extensive "structure" to keep everything in place, and many people who sew quite well otherwise simply lack the expertise to pull off evening wear and speciality gowns.
