PHYSICAL ACTIVATION OF WOODEN CHIPS AND THE EFFECT OF PARTICLE SIZE, INITIAL HUMIDITY, AND ACETIC ACID EXTRACTION ON THE PROPERTIES OF ACTIVATED CARBONS

In this research study, Chair two different wooden biomasses (birch and pine) were thermally carbonized and steam-activated into activated carbons in a one-stage process.The effects of particle size and humidity (as received and oven-dried) on the properties, such as specific surface areas, pore volumes, and pore size distributions, of the final ac

DE200 and DE405 are Development Ephemeris (DE) series released by the National Aeronautics and Space Administration (NASA) in 1981 and 1997.NASA uses DE405 to predict solar eclipses in 2011-2020.While before 2011 and after 2020 NASA uses VSOP87/ELP200 theory-based DE200.Why Adaptive Cutlery NASA not only use more updated series DE405 and still use

A study of Muffin Pans an elastic rotor supported by two defect bearings is presented.The bearing behavior must be considered non-linear because of the defect effects.The rotor is modelled by typical beam finite element including effects such as gyroscopic effect.The dynamic behavior is analysed using an unsteady time integration procedure.A modal

Undoubtedly, new developments in information and trading technologies have increased the integration of international financial markets in the world.This in turn has generated interest in examining the volatility transmission of financial market across markets.In this paper, we investigate the co-movements and volatility transmission among the thre

The Jabal Al Bayda, located in the Hijaz terrain of northwest Saudi Arabia, comprises magmatic rocks that represent the ending phase in the Precambrian development of the Arabian Shield.Two granitic suites have been studied petrologically and geochemically, the monzogranite and alkali granite suites, to gain knowledge about their origin and geotect
