Effects of Oxidized Brown Coal Humic Acid
Field experiments were carried out during 2011-2014 at the Research and Experimental 13 Center to Combating Desertification located in the Elsen Tasarkhai station of central Mongolia. The 14 study was aimed to identify the effects of oxidized brown coal humic acid fertilizer on the relative 15 growth rate of several trees for forest rehabilitation. The trees used were Populus sibirica, Salix 16...
متن کاملA tale of two Germanys
Editor—The fall of the Berlin Wall in 1989 marked the beginning of the end of communism in eastern Europe and in eastern Germany. As McKee and Fister point out, certain constellations of epidemiological and demographic variables characterise the resultant process of political and economic transition: low or even decreasing life expectancy (especially for men) and higher prevalences of alcoholis...
متن کاملRetention of cobalt on a humin derived from brown coal.
In this work, the retention of cobalt on a humin (HU) derived from a brown coal is studied. Through a systematic and coordinated investigation of the behavior of the metal ions in solution (speciation diagrams as a function of pH) and their adsorption and precipitation processes with reactive functional groups of the solid (sorption isotherms), the interactions of different Co(II) species with ...

Extrakty, získané metódou SFE, boli podrobené plynovej chromatografii s hmotnostno-spektrometrickou identifikáciou (GC MS). Porovnaním s literárnymi údajmi hmotnostnej spektroskop...
متن کاملEmission factors and light absorption properties of brown carbon from household coal combustion in China
Brown carbon (BrC) draws increasing attention due to its effects on climate and other environmental factors. In China, household coal burned for heating and cooking purposes releases huge amounts of carbonaceous particles every year; however, BrC emissions have rarely been estimated in a persuasive manner due to the unavailable emission characteristics. Here, seven coals jointly covering geolog...
