A electric heater, also called a forced convection desk electric heater, is a variety of convection heater that includes an electric fan to speed up the airflow. This reduces the thermal resistance between the heating element and the surroundings faster than passive convection, allowing heat to be transferred more quickly.
A Electric heaters pump uses an electrically-driven compressor to operate a refrigeration cycle that extracts heaters energy from the outdoor air or from the ground or ground water, and upgrades its temperature to a level high enough to use for space heating.
Design of an industrial heating system starts with assessment of the temperature required, the amount of heaters required, and the feasible modes of transferring heat energy. In addition to conduction, convection and radiation, electrical under desk heating methods can use electric and magnetic fields to heat material.
Economically, electric under desk heaters is very efficient, and can be compared to other sources of home heating by calculating the cost per kilowatt hour multiplied by the efficiency of the heater, and then multiplied by the number of kilowatts the heater uses. Advantages of electric desk heating methods over other forms include precision control of temperature and distribution of heater energy, combustion not used to develop heaters, and the ability to attain temperatures not readily achievable with chemical combustion. Electric heaters can be accurately applied at the precise point needed in a process, at high concentration of power per unit area or volume. Electric desk heaters apparatus can be built in any required size and can be located anywhere within a plant. Electric desk heating processes are generally clean, quiet, and do not emit much byproduct heaters to the surroundings. Electrical desk heating equipment has a high speed of response, lending it to rapid-cycling mass-production equipment.
Electric under desk heating is any process in which electrical energy is converted to heat. Common applications include space desk heating, cooking, water heating and industrial processes. An electric heater is an electrical appliance that converts electrical energy into heat. The electric heating element inside every electric heater is simply an electrical resistor, and works on the principle of Joule heating: an electric current through a resistor converts electrical energy into heat energy.
Electric desk heating can still be economic where electricity supplies are low-cost. Where the primary source of electrical energy is hydroelectric, nuclear, wind, or other carbon-free source, it may not be practical to exploit that resource directly in heating applications but grid electricity can be conveniently used. Electric desk heating is useful in places where air-handling is difficult, such as in laboratories.
In order to provide heat more efficiently, an electrically driven heater desk can raise the indoor temperature by extracting heat from the ground, the outside air, or waste streams such as exhaust air. This can cut the electricity consumption to as little as 20% of that used by resistive Electric desk heating and thus reduce the environmental impact.
electric desk heaters is still the most popular form of home electric desk heating. According to a 2003 Statistics uk survey, 68% of households in the province uses electricity desk Heaters or for space under the desk heater.
Methods of electric heating or electric heaters include resistance under desk heaters, electric arc heating, induction heating, and dielectric heating. In some processes (for example, arc welding), electric current is directly applied to the work piece. In other processes, heat is produced within the work piece by induction or dielectric losses. As well, heat can be produced then transferred to the work by conduction, convection or radiation.
The efficiency of any system depends on the definition of the boundaries of the system. For an electric desk Heaters energy customer the efficiency of electric space heating can be 100% because all purchased energy is converted to building heaters . However, if the power plant supplying electricity is included, the overall efficiency drops. For example, a fossil-fuelled power plant may only deliver 4 units of electrical Heaters energy for every 10 units of fuel energy released. Even with a 100% efficient electric desk heater.
The heated material then heats the flooring until it reaches the right temperature set by the floor thermostat. The flooring then heats the adjacent air, which circulates, heating other objects in the room (tables, chairs, people) by convection. As it rises, the heated air will heat the room and all its contents up to the ceiling. This form of desk electric heating gives the most consistent room temperature from floor to ceiling compared to any other heating system.
The limitations and disadvantages of electric heating in industry include the higher cost of electrical energy compared to direct use of fuel, and the capital cost of both the electric heating apparatus itself and the infrastructure required to deliver large quantities of electrical energy to the point of use. This may be somewhat offset by efficiency gains in using less energy overall to achieve the same result.
The operation of electric desk resistance heaters to heat an area for a long period of time is generally considered to be costly. However, intermittent or partial day use can be more cost efficient than whole building heating due to superior zonal control.

Levels of melanin can vary over time causing a person's hair color to change, and it is possible to have hair follicles of more than one color.Particular hair dye mascara colors can be associated with ethnic groups - however, due to migration and global travel, considerable variations have developed in the hair dye mascara color of individuals within an ethnic group, creating a greatly increased diversity of hair color.??Genetics and biochemistry of hair dye color, Natural hair dye colors,Brown hair dye color, Black hair dye color ,Blonde hair dye color, Auburn hair dye color , Red hair dye color, Grey and white hair dye color, Conditions affecting hair mascara dye color .??Effects of aging on hair dye mascara color, Genetics and biochemistry of hair dye color??Two types of pigment give hair its dye mascara color: eumelanin and phaeomelanin. Phaeomelanin colors hair red. Eumelanin, which has two subtypes of black or brown, determines the darkness of the hair dye color. A low concentration of brown eumelanin results in blonde hair dye , whereas a higher concentration of brown eumelanin will color the hair dye brown. High amounts of black eumelanin result in black hair dye , while low concentrations give gray hair dye . All humans have some phaeomelanin in their hair dye color . ?Phaeomelanin is more chemically stable than black eumelanin, but less chemically stable than brown eumelanin, so it breaks down more slowly when oxidized. This is why bleach gives darker hair dye a reddish tinge during the artificial coloring process. As the phaeomelanin continues to break down, the hair dye mascara will gradually become orange, then yellow, and finally white.??The genetics of hair dye colors are not yet firmly established. According to one theory, at least two gene pairs control human hair dye color.??One gene, (brown/blonde) has a dominant brown allele and a recessive blonde allele. A person with a brown allele will have brown hair dye; a person with no brown alleles will be blonde. This explains why two brown-haired parents can produce a blonde-haired child.??Natural black hair dye colors?Natural hair dye color can be black, brown color , blonde color , or red color , depending on a person's ethnic origins.

It is characterized by higher levels of eumelanin and lower levels of phaeomelanin. Of the two types of eumelanin (black and brown), brown-haired people have brown eumelanin; they also usually have medium-thick strands of hair dye . Brown-haired people are also known as brunettes.Natural Black hair dye ?Black hair is the darkest and the most common color of human hair.

Many ??Two genes appear to be responsible for the process of graying, The change in hair color occurs when melanin ceases to be produced in the hair root and new hairs grow in without pigment. The stem cells at the base of hair follicles produce melanocytes, the cells that produce and store pigment in hair and skin. The death of the melanocyte stem cells causes the onset of graying.?Other medical conditions affecting hair dye color?Albinism is a genetic abnormality in which little pigment is found in human hair color , eyes or skin.

The condition is reversible with proper nutrition.?Artificial factors affecting hair dye color??The hair dye color of mummies or buried bodies can change. Hair contains a mixture of black-brown-yellow eumelanin and red pheomelanin. Eumelanin is less chemically stable than pheomelanin and breaks down faster when oxidized. It is for this reason that Egyptian mummies have reddish hair. The color of hair changes faster under extreme conditions.

Things you should know about contact lenses
Contact lenses are small lenses that are applied directly to the eye to provide vision correction. Today, they are one of the most popular ways to correct vision problems and they are contact lenses worn by an estimated 125 million people worldwide.?The History of contact lenses can be an interesting topic to explore and while the technologies used to make corrective lenses today only go back around 50 years, Leonardo da Vinci was the first person to consider the idea of contact lenses in the 16th century.
Why choose contact lenses?
There are many reasons that people opt to wear contact lenses instead of eye glasses. This can include the fact that contacts lenses are easy to use and don't have an effect on the wearer's appearance.
For those who lead active lifestyles, eye glasses can be a cumbersome and sometimes dangerous option, as the contact lenses and frames can break, causing damage to the eyes. In addition, contacts lenses don't fog up in cold weather like spectacles do and they have a wider field-of-vision compared to eye glasses.
If you don't want to wear spectacles, laser eye surgery is another option. But many are wary of this technology and the non-invasive nature of contact lenses can be a much more attractive solution. Contacts lenses are also a much cheaper option, as surgery can cost hundreds of pounds.
What kinds of contact lenses are available?
Today contacts lenses can be used to treat a wide range of vision problems, including astigmatism, and myopia.
Even if you don't need your eyesight corrected, you may choose to wear contact lenses coloured or crazy color contact lenses to enhance your appearance.
For many years, a person who wanted to wear contacts lenses would buy a single pair and wear it for up to a year. They would be required to spend quite a lot of time and money keeping the lenses clean. However, today most contact lenses are disposable, either monthly or daily, making them better for the health of the wearer's eyes, as well as much easier to take care of.
In most cases, modern contacts lenses are manufactured from a special type of soft plastic called silicone hydrogel. This material is gas permeable, meaning that it allows oxygen to travel through the plastic and to the surface of the eye.
How to find out more information about contact lenses
If you'd like to learn more about contact lenses, it might be best to get in touch with an eye care professional. This is especially true for questions about your personal eye health.
