INTERNATIONAL UNITS OF THE SYSTEM

S.I. UNITS
 In an additional continuation of our theme mentioned above, the concept can often be easily accessible and comprehensible if we are familiar with the SI units of the physical quantity, Prefixes, symbols, values, symbols of Greek letters used in the unit. The complete knowledge of all this physical quantity helps us to understand the subject very clearly. Before entering the individual theme of the topic, let us familiarize ourselves with the physical quantities.
 UNITS
 The reference standard for measurement is called a unit. The measure of a physicist the quantity is necessary because, without it, we cannot study the characteristics of the problem. There are seven physical quantities, the length, the mass, the time, the electric current, the temperature, the intensity of the light and the amount of substance are Called fundamental physical quantities.
 DERIVATIVE UNITS
 All those units in physics, that is, derived from the units of length, mass, time, electric current, the temperature, the intensity of the light and the amount of substance are called derived units. The common systems of a unit for measurements are the C.G.S system, the F.P.S system, the M.K.S. system and the S.I. system
 The C.G.S system is based on three basic units, the centimeter, the gram and the second for the length, the measurements of mass and time, respectively. The F.P.S system or the UK system is based on three basic units, the foot, the pound and the second for the length, mass and time, respectively.
 The M.K.S system is based on the three basic units, the subway, the kilogram and the second for the length, mass and time, respectively.

 WHAT IS S.I SYSTEM? This system is now accepted internationally. Represents the INTERNATIONAL SYSTEM d ' UNITS These are the length meter, the kilogram of the mass, the second for time, Kelvin (k) for temperature, ampere (A) for current, candela (cd) for light intensity and moll (mol) for a quantity of the substance. This system is used by almost all countries of the world because all the units are well defined and are easily reproducible the places. All units do not change with time, place, pressure, temperature, etc. because they depend on some fundamental property of the ATOM. In the S.I system, the energy unit (all forms) it is joule and watt as the unit of power. (all forms)INTERNATIONAL UNITS OF THE SYSTEM (S.I. UNITS)

Energy used for specific jobs

    One thing that is not discussed here is the energy used for specific jobs only power.  For example, refrigerators turn on and off. Therefore, a refrigerator that runs almost full time can be cooled with the same energy but at lower power than a cycle in which each cycle consumes more energy. Energy = Power for time. Secondly, all kinds of devices now use motors in inverters or other electronic devices that control the frequency or voltage, giving the motors only the speed and, therefore, the power needed to perform a specific job. On-demand water pumps come to mind and offer only the pressure and flow rate required and nothing more. Needless to say, the power required is only what is needed for that pressure and volume. So far, less energy is wasted. Apparently, the team that is discussing works according to this principle. But, whether DC is operated from rectified AC or inverted DC to Poly Phase AC, the specific design used is unknown.

Transfer technique produces wearable gallium nitride gas sensors

------------------------------------------------ Transfer technique produces wearable gallium nitride gas sensors A transfer technique based on thin sacrificial layers of boron nitride could allow high-performance gallium nitride gas sensors to be grown on sapphire substrates and then transferred to metallic or flexible polymer support materials. The technique could facilitate the production of low-cost wearable, mobile and disposable sensing devices for a wide range of environmental applications. Transferring the gallium nitride sensors to metallic foils and flexible polymers doubles their sensitivity to nitrogen dioxide gas, and boosts response time by a factor of six. The simple production steps, based on metal organic vapor phase epitaxy (MOVPE), could also lower the cost of producing the sensors and other optoelectronic devices. Sensors produced with the new process can detect ammonia at parts-per-billion levels and differentiate between nitrogen-contain
