TDS = k e EC. where TDS is expressed in mg/L and EC is the electrical conductivity in microsiemens per centimeter at 25 °C. The conversion factor k e varies between 0.55 and 0.8. [5] Some TDS meters use an electrical conductivity measurement to the ppm using the above formula. Regarding units, 1 ppm indicates 1 mg of dissolved solids per 1,000 ...
Tax deduction at source (TDS) has come into existence with the motive of collecting tax from different sources of income. As per this concept, a person (Payer) who is responsible to make payment of specified nature to any other person (Payee) shall deduct tax at source before making payment to such person (Payee) and remit the same into the account of the Central Government.
Temperature programmed desorption (TPD) is the method of observing desorbed molecules from a surface when the surface temperature is increased. When experiments are performed using well-defined surfaces of single-crystalline samples in a continuously pumped ultra-high vacuum (UHV) chamber, then this experimental technique is often also referred to as thermal desorption spectroscopy or thermal ...

GST is levied on most transactions in the production process, but is refunded with exception of Blocked Input Tax, to all parties in the chain of production other than the final consumer. The existing standard rate for GST effective from 1 April 2015 is 6%.
The first and second law of thermodynamics are the most fundamental equations of thermodynamics. They may be combined into what is known as fundamental thermodynamic relation which describes all of the changes of thermodynamic state functions of a system of uniform temperature and pressure.
The formula calculator concept can be applied to all types of calculator, including arithmetic, scientific, statistics, financial and conversion calculators. The calculation can be typed or pasted into an edit box of: A software package that runs on a computer, for example as a dialog box. An on-line formula calculator hosted on a web site.
The goods and services tax [1] (GST; French: Taxe sur les produits et services) is a value added tax introduced in Canada on January 1, 1991, by the government of Prime Minister Brian Mulroney. The GST, which is administered by Canada Revenue Agency (CRA), replaced a previous hidden 13.5% manufacturers' sales tax (MST).
