the objective of this study was to assess the adsorption potential of activated carbon (ac) asan adsorbent for the removal of murexide (mu) from aqueous solutions. the influence of variablesparameters including ph, amount of adsorbent, sieve size of adsorbent, temperature and contact timeon mu removal was studied. following optimization of variables, the relation between concentrations ofdye re...

H E problem of position effect has been studied with the purpose of T elaborating upon the larger problem of gene action. DUBININ and SIDOROPP (1934) first showed the position effect of the fourth chromosome locus, cubitus interruptus, ( c i ) , in Drosophila melanogaster. They found that in translocations involving the fourth chromosome, the normal allele both in hemior homozygous constitution...

ARIEGATED-type position effect in Drosophila melunoguster has received a V considerable amount of attention from many investigators (See review by LEWIS 1950). Direct proof of this phenomenon has been obtained for only two cases however. DUBININ and SIDOROV (1935) showed that the action of the gene for hairy (h) was affected when this locus was placed near heterochromatin of the fourth chromoso...

Cationic dextran hydrogels having pendent 51-59 mol% N-alkyl-N,N-dimethylammonium chloride groups were synthesized and tested as adsorbents for sodium cholate. The bile acid salt sorption by these gels was evaluated equilibrium analysis in water 10 mM NaCl solution. best adsorption results obtained with amphiphilic dextran-based two types of pendant ammonium different polarities. Experimental d...

The abatement of particulate matter in gasoline direct injection (GDI) engines requires the use filters. In turn, optimisation their regeneration is based on a deep knowledge soot oxidation behaviour. determination intrinsic kinetic parameters GDI explored thermogravimetric analysis (TGA) and reaction rate modelling. New understanding provided enabling an accurate prediction wide range temperat...
