The charging process consists of moving a hopper vehicle to the charging position, charging coal (e.g. with belt feeder or screw feeder), then waste plastics, and finally covering with coal, and moving to the coke oven. Bal~z, P. et ,l. Fuel, 2001, 80, (5), 665-671. The aim of this work has been to point out the possibility of using GACL process for chemical cleaning of brown coal Nov~ky (Slovakia) and Pittsburgh No. 8 coal. Simultaneous grinding and aqueous chemical leaching, which is the principle of the process, reduces the inorganic and inorganic sulfur content in both coals. Dearsenification nearly up to 96% is detected in GACL-treated samples of Nov~ky coal. The possibility of enhancing the recovery of humic acid as a consequence of GACL treatment is demonstrated. The process under study works under atmospheric pressure, temperature of 90ยฐC and NaOH consumption, which is six times lower compared with the MCL process. Further research is needed to minimize the wear of grinding media and to improve the washing step.

The temporal variation in a soil moisture profile can be studied using resistivity sounding data acquired at different times. The layered earth model based estimation of soil moisture from apparent resistivity data is a two-step non-linear inversion. Firstly, the apparent resistivity data are invert
