the relationship between learners critical thinking ability and their performance in the reading sections of the tofel and ielts test
the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
15 صفحه اولThe fourth arginine catabolic pathway of Pseudomonas aeruginosa.
D-Arginine dehydrogenase activity was discovered in Pseudomonas aeruginosa. This enzyme was inducible by its substrate, D-arginine, as well as by its product, 2-ketoarginine, but not by L-arginine. The enzyme activity was measured in vitro, in the presence of artificial electron acceptore (phenazine methosulphate and iodonitrotetrazolium chloride). 2-ketoarginine was catabolized further to 4-gu...

Metabolism of basic amino acids in Pseudomonas putida. Intermediates in L-arginine catabolism.
y-Guanidinobutyrate amidinohydrolase, the third enzyme of L-arginine catabolism in Pseudomonas putida, has been purified 6%fold from extracts of cultures grown on L-arginine. Synthesis of the amidinohydrolase is induced by growth on L-arginine or y-guanidinobutyrate, but not by growth on y-aminobutyrate or on urea plus DL-malate. Hydrolysis of y-guanidinobutyrate to y-aminobutyrate and urea pro...
