A new site, Bux to has been attracting large amounts of users to it. However, is this mordacious site a abhorrent scam?
First, I had approximetly 130 bucks my account. On June 8, I requested a payment of 131 dollars to my alertpay account. However, it is the 2 of January and I still hadn't gotten my payment yet. Bux to does an amazing job covering up their inside. From the outside, they look like a trustworthy earning website. Soon, you realize that this was just a pyramid scheme after all.

Making Money Online Part 1
Too young to get a real job, don't worry, there are several high-paying jobs on the market that you can earn a living right in your couch.
1. Bux.To
A great site which is a click pay site. Earn a cent per each of your clicks or your referal clicks. I made almost 400 bucks out of this. However, the main disadvantage is that it takes a longer time to get paid than other sites.
www.bux.to.com
2. Gangstergreed www.gangstergreed.com
On this site, you get paid for reviewing offers online. This includes taking surveys. However, it requires sometimes to take extremely tedious surveys that take up to 30 minutes. Some 5 surveys can be worth around 1-5 bucks. The site is also creditable because it lacks the scamming part of many survey websites.
3. Triond www.triond.com
On this website, you get paid for writing articles, poetry, uploading pictures, and video. However, earnings are relatively low for the lower writers. I enjoy this site because once the earnings come in, they never stop!

The 4 Tips on staying asleep and falling asleep
Sleep, one of the most important processes in life. You may think your body just relaxes during speech, but it does much more. Your body produces hormones and adequate sleep can help you live a longer and healthier life. See this for more info about a healthy lifestyle:

http://www.healthmad.com/Health/How-to-Live-a-Long-Life-Guaranteed.284785Last night, you couldn't fall asleep and you have no clue why. Perhaps you were thinking too much, but why? Don't worry, I now have control over my sleep insomnia. Several years ago, I had trouble falling asleep. I had no clue why this happened, but after sometime on the web, I realized how I could control it. Lets see some tips on how to fall asleep and stay asleep:1. Practice Good Sleep HygieneNot the most specific tip, but this can be divided into many categories. Do something relaxing before bed such as reading a book or accumulating fine writing into your journal. Don't do something that gets you agitated and makes you stressed or upset. This can cause stress hormones such adrenaline which can alert your mind and prevent it from sleeping. However, taking a bath and drinking a warm cup of milk or soy milk have a chemical called tryptophan that relax your body and induce sleep. However, do not consume drinks that have caffeine or artificial sweeteners which can cause hyperactivity and hard time sleeping. Do not sleep when you aren't tired which increases the time in bed. Also, practice the use of the bed where you rest not where you do financial accounting or playing games. Go outside for sometime and have the sun set your sleep clock.
2. Don't Go in Bed if you aren't feeling sleepyChances are, you wouldn't fall asleep as quickly as if you are tired. Your body only falls asleep when it is tired and bored, so try to do something boring such as reading the newspaper, not on the bed. Once you are sleepy, go to the bed and sleep. Remember, if you can't fall asleep in 30 minutes, you probably are not going to fall asleep for at least another hour. So, get up and do something boring such as watching t.v., not something which makes you elated. Also when sleeping, try to act that your body is going to sink into the mattress. This coaxes and relaxes the muscles. Sometimes, if you think that you are tired, your body produces hormones which make you sleepy.
Stay off the Sleeping Pills (Sedatives)
3. Take it EasyDon't stress out that you aren't falling asleep. If there is a clock in the room, take it out to prevent yourself from looking at it. If you have sleep insomnia, you probably wouldn't sleep for at least an hour. For me, it took me around 45 minutes to fall asleep, now takes less than half an hour. Don't do strenuous physical activity before 3 hours of bed time. This has time for your muscles to relax and rejuvenate. Take a warm bath 1 hour before lights out. Also, try to have a conversation of how the days going with a spouse or relative. Do whatever you want that bores you to sleep. 4. Adjust your roomMake sure it is dark or doesn't have any lights that distract you from sleeping. Make the room a few degrees below room temperature. Don't galore yourself with blankets. Don't put distracting items such as a computer, television, etc. in your room. This just makes you disturbed from sleep. Make your room soundproof so that sounds do not keep you awake throughout the night.
Importance of Sleep:Sleep, it may be not as important as it sounds, but it is a vital process in the human body. In the eccentric world of sleep, the body produces hormones and goes through several stages. REM (Rapid Eye Movement) is the last stage in which people experience bizarre and preternatural tales which is also known as dreams. The heart rate and breathing goes up like the body is actually witnessing the event. Lack of sleep contributes to hormonal imbalances, metabolic problems, increased risk of obesity, cardiovascular decline, stress during day, fatigue, decline in the white bloods in the immune system, and also body pains.
Sleep cycle Sleep Insomnia: If you can't fall asleep or stay asleep for several hours, you could be at risk for a condition called sleep insomnia. However, don't worry, it is easy to defeat. If you have sleep insomnia or other problems, try to not take sleeping pills that contain drugs. Sleep insomnia is very easy to take care of and is majorly caused by stress, work problems, ignorance. Following the tips above prove very efficient to controlling this malignant condition.

How Heat Transfer Works
is separated into three sections. Heat can be transferred from a warmer to cooler object by conduction, convection, and radiation. Each of the various types are similar and different in many ways.
To start out, convection is heat transfer through a fluid (liquid and gas). Convection happens when a fluid is heated. The part nearest the heat source expands. The kinetic energy increases as molecules move faster and contract. The heated fluid becomes less dense. Density is the amount of mass in a volume. The fluid is forced to rise because it is less dense than the cooler, more compact fluid. When it reaches the surface, the warmer liquid starts to diffuse and expands to the sides. At the surface, it cools down and the fluid sinks. The heat source then reheats the liquid. The liquid then goes over the same process over and over again. These are called convection currents. Convection currents continue until the heat source has been removed and the molecules are the same temperature. Convection currents are a chain of movement by heat through a liquid when there is a heat source. Unlike radiation, convection can be visible sometimes. Convection, along with radiation and conduction happen near earth’s surface. Convection, conduction and radiation all involve a heated object. Convection does not transfer heat through electromagnetic waves. Some examples of convection are in the asthenosphere, troposphere, and even at homes. In the asthenosphere (a layer between 100-200 miles below the earth’s crust, right above the mantle) the magma in the asthenosphere which is nearest the mantle rises because it is heated by the mantle. Once it reaches the top, it expands to the sides, the fluid sinks, the fluid gets heated again. Convection causes more warming than radiation and conduction in the troposphere (the lowest layer of atmosphere). The air near the ground gets heated and the molecules have more kinetic energy. They crash into each other and expand farther out. When it moves farther out, it becomes less dense. The cooler more dense air stays at the bottom, while the warmer flows into the troposphere. Some home appliances that involve convection are heaters and refrigerators. Heaters are a combination of both convection and radiation. The heater sends out electromagnetic waves which is radiation. The heat which escapes from the heat sources is force to rise because it is less dense than the cooler air around it. At the top of the house, it expands towards the sides, it starts to cool, and then it sinks as the heater heats the air again. Refrigerators use convection currents in order to stay cool. There is a heat absorber on the bottom and a cooler on the top. The warmer air rises through narrow tube and it goes to the cooler on the top. Once it cools, it goes through an open place where the food is. It cools the food as the cool air sinks down. It is then heated again and continues in the repeating cycle again and again.
In addition, radiation is another way of heat transfer. Radiation is the transfer of heat in contact with electromagnetic waves through an empty space. Unlike radiation and convection, radiation does not involve direct contact between molecules. Radiation is the only form of heat transfer which can cross a vacuum (a space which is empty of matter).It is also the only form of heat transfer which transfers by waves. There are many types of radiation. One is infrared radiation. Infrared radiation travels directly to an object. Infrared radiation causes the greatest temperature increase. Examples of infrared radiation is heat from the sun, heaters, lamps, light bulbs, etc. The sun’s radiation is mostly made out of visible light radiation and infrared radiation. A small portion is also made out of ultraviolet radiation, a very dangerous type of radiation. An effect which infrared radiation causes is the greenhouse effect. When heat enters a space, only 50 percent of the heat can escape. This is the cause of global warming.
Furthermore, conduction is another form of how heat can be transferred. Conduction is heat transfer by direct contact within particles of matter. Conduction can only be transferred through solids unlike convection. The energy nearest the heat source increases, the particles start vibrating and spread on some of their energy, spreading heat through the whole solid. Unlike radiation, conduction needs direct contact with particles. Both conduction and convection need matter to transfer heat. Metals are good conductors because they have freely moving electrons which pass energy more efficient. Substances that conduct heat slowly are called insulators. Wood and water are examples of insulators. An example of conduction uses a pan, some water, and a metal spoon. Once after some time, the metal spoon gets heated by conduction because particles near the bottom vibrate faster when they are heated, they bump into cooler molecules. Eventually, the whole spoon heats up. Another example of conduction is the desert. The sun heats up the top layer of sand on the desert, so it becomes extremely hot. When someone steps on the sand, conduction transfers some of the heat to the barefoot of the person. When someone is wearing a leather shoe, it is a better insulator then a regular foot so it takes longer for it to heat up. The molecules gain energy every time they pass some energy to nearby molecules. The ability to transfer heat within an object is called thermal conductivity.
Clearly, conduction, convection, and radiation are the ways heat can be transferred from warmer to cooler object. The three types of heat transfer each have their very own unique characteristics. The type of heat transfer will vary because of the substance (fluid or solid) and how heated is transferred.
To start out, convection is heat transfer through a fluid (liquid and gas). Convection happens when a fluid is heated. The part nearest the heat source expands. The kinetic energy increases as molecules move faster and contract. The heated fluid becomes less dense. Density is the amount of mass in a volume.

At the surface, it cools down and the fluid sinks. The heat source then reheats the liquid. The liquid then goes over the same process over and over again. These are called convection currents.

When someone is wearing a leather shoe, it is a better insulator then a regular foot so it takes longer for it to heat up. The molecules gain energy every time they pass some energy to nearby molecules. The ability to transfer heat within an object is called thermal conductivity.
Clearly, conduction, convection, and radiation are the ways heat can be transferred from warmer to cooler object. The three types of heat transfer each have their very own unique characteristics. The type of heat transfer will vary because of the substance (fluid or solid) and how heated is transferred.
The Electric Car: The Secret Behind That Ingenious Technology
Simply put, an electric car is a car that is driven by some electric motors, which take their power from an onboard source of power-the batteries. The batteries give power to the controller, which in turn regulates the amount of power needed to drive the engine. There are two types of electric cars; battery-operated electric vehicles and hybrid electric vehicles.
There are actually two types of electric cars: battery-operated electric vehicles, and hybrid electric vehicles. A battery-electric vehicle (BEV) uses only electric motors. The electricity for the motors is stored in a battery that must be recharged from an external power supply. Finding a BEV on the road is extremely rare. A hybrid electric vehicle (HEV) uses electric motors and an internal combustion engine (ICE). An HEV is the type of hybrid you see on the road, like the Toyota Prius. This essay will talk about in more detail about how these two hybrids work.
Electric vehicles are powered by one or more electric motors that are "fueled" by electricity. The source of the electricity may be rechargeable batteries, fuel cells, or photovoltaic solar cells that convert the sun's energy into electricity. However, since fuel cell and photovoltaic solar cell vehicles are not currently available to customers, this article will focus on electric cars that run on rechargeable batteries. A law of nature that is critical to an understanding of anything that moves or does work is that energy cannot be created or destroyed. It can only be moved from one point to another. This is an important law to consider when trying to understand the efficiencies of an electric drive vehicle. The internal combustion engine is a loved, but very inefficient machine. Although there are some energy losses with electric drive, the amount is very low if the vehicle is designed properly. One of the keys to the overall efficiency of an electric drive vehicle is called regenerative braking. Regenerative braking is the process by which a vehicle's kinetic energy can be captured while it is decelerating and braking. Whenever the driver applies the brakes in a conventional car, friction converts the vehicle's kinetic energy into heat. That heat is useless to the car and becomes lost energy. The operation of most electric drive vehicles is based on batteries, electric motors, and electric generators. Batteries supply the power to operate the motors. The motors take that electrical power and change it to mechanical energy, which rotates the wheels and allows the vehicle to move. A generator takes the kinetic energy, or the energy of something in motion, and changes it to energy that charges the batteries. When the generator is operating during regenerative braking, it helps slow down the vehicle. The rotation of the wheels turns the generator, which generates a voltage to charge the batteries. Because of the magnetic forces within the generator, the vehicle slows down. A conventional brake system is used in conjunction with the regenerative brake system to bring the vehicle to a safe stop. Regenerative braking can recover about 30% of the energy normally lost as heat when a vehicle is slowing down or braking. Regenerative braking is unique to electric drive vehicles. A battery-operated electric vehicle, sometimes referred to as a battery-electric vehicle (BEV) uses one or more electric motors to turn its drive wheels. The electricity for the motors is stored in a battery that must be recharged from an external electrical power source. This technology is used for passenger cars, forklifts, urban buses, airport ground support equipment, and off-the-road industrial equipment. BEVs are zero-emission vehicles because they do not directly pollute the air. The only pollution associated with them is the result of creating the electricity to charge their batteries. Even when those emissions are included, BEVs are more than 99% cleaner that the cleanest ICE vehicle. Normally, a battery-operated vehicle drives the same way as any other, but it is quiet and carries no fossil fuel. However, rather than filling a tank with fuel, you need to recharge the batteries. The batteries are recharged by plugging them into a recharging outlet at home or other locations. Currently, there are no BEVs widely available to customers since they cost a lot, the batteries were expensive, and the limited driving ranges-around 120 miles-before the batteries needed to be recharged. A BEV's electricity supply comes from one or more of the following items: atomic power, coal, gas petroleum, or hydroelectric power. This is converted into electricity, which enters the car. The electricity is stored in the batteries, until it is needed. When electricity is needed, it gets sent to the controller, the device that regulates the flow of electricity into the electric motor(s). The motor(s) turn the transmission, which powers the drive wheels, or in the case of a four-wheel drive, all the wheels. A hybrid electric vehicle (HEV) uses one or more electric motors and an ICE to propel the vehicle. Depending on the design of the system, the ICE may propel the vehicle by itself, act together with the electric motor to propel the vehicle, or it may drive a generator to charge the vehicle's batteries. The electric motor may propel the vehicle itself or assist the ICE while it is propelling the vehicle. Some hybrids rely exclusively on the electric motor(s) during slow speed operation, the ICE alone at higher speeds, and both during some driving conditions. A hybrid's electric motor is powered by batteries, which are continuously recharged by a generator that is driven by the ICE. The battery is also recharged through regenerative braking. Complex electric controls monitor the operation of the vehicle. Based on the current operating conditions, electronics control the ICE, electric motor, and generator. The system recharges the batteries while driving, therefore plug-in charging is not required. The engines used in

hybrids are specially designed for the vehicle and electric assist. Therefore, they can operate more efficiently, resulting in very good fuel economy and very low tailpipe emissions. Hybrids will never be true zero-emission vehicles, however, because they have an ICE. HEVs have an extended range, going further that a BEV can on just the charge in its batteries. They also have a longer driving range that a comparable ICE-equipped vehicle. HEVs also provide the same performance, if not better, as the same vehicle equipped with a larger ICE. The delivery of power to the wheels is smooth and very responsive. There are two types of hybrids: the parallel and the series designs. A parallel HEV uses either the electric motor or the gas engine to propel the vehicle, or both. A true series HEV only uses the ICE to power the generator to keep the batteries charged. The vehicle is powered only by the electric motor(s). All electric vehicles are definitely more environmentally friendly, so choose any electric car avaliable, scrape some money together, and go right to the store and buy one today! This picture shows the Aptera, a very efficient electric car-it gets 120 miles per gallon! It is currently for sale in California, with a price tag of about $27,000.
