quantitative structure-property relationship (qspr) for estimating the adsorption of aliphatic alcohols onto activated carbon were developed using substructural molecular fragments (smf) method. the adsorption capacity of activated carbon (gr/100grc) for 150 aliphatic alcohols onto activated carbon (ac) is studied under equilibrium conditions. forward and backwards stepwise regression variable ...

Abstract Aiming at the problem of jitter in speed when load changes abruptly during operation a synchronous reluctance motor and poor resistance to disturbance, an integral type sliding film variable structure control algorithm is proposed. The regulation controlled by mode, PI controls current regulation, Simulink simulation model system built, experiments are conducted. results show that, com...

Brain Tumor is an unwanted mass when cells grow abnormally. It puts pressure on certain areas of the brain which dangerously affects its functioning. For severe tumors like malignant, surgery not a good option because they do have definite boundaries and are closely attached with other healthy tissues brain. So chemotherapy preferable in this case to avoid damaging cells. The primary intention ...
