exploring motivation and english test preparation strategies of iranian pre-university candidates during and at the end of test preparation period for konkur examination
the current study aimed at investigating the relationship between motivation and test preparation strategies (tpss) used by iranian pre-university students in their preparation period for the university entrance exam (uee). due to the importance of uee in iran, this study also attempted to show its impact on these two important variables. to this end, 100 pre-university students in an iranian p...
Preparation of the methyl ester of hyaluronan and its enzymatic degradation.
A methyl ester of hyaluronan in which the carboxyl groups were fully esterified was prepared using trimethylsilyl diazomethane. This derivative, while not depolymerized by hyaluronan lyases or hyaluronan hydrolases, was a substrate for both chondroitin ACI lyase (EC 4.2.2.5) from Flavobacterium heparinum and chondroitin ACII lyase (EC 4.2.2.5) from Arthrobacter aurescens. The major product isol...
متن کاملPreparation and Enzymatic Degradation of Porous Crosslinked Polylactides of Biomass Origin
To understand the enzymatic degradation behavior of crosslinked polylactide (PLA), the preparation and enzymatic degradation of both thermoplastic (linear) and crosslinked PLAs that have pore structures with different dimensions were carried out. The porous structures of the linear PLA samples were of micro and nanoporous nature, and prepared by batch foaming with supercritical CO2 and compared...
متن کاملRapid Enzymatic Degradation
The effect of plasma on degradation of human growth hormonereleasing hormone (GRH) was examined in vitro and in vivo using high performance liquid chromatography (HPLC), radioimmunoassay (RIA), and bioassay. When GRH(1-44)-NH2 was incubated with human plasma, the t1/2 of total GRH immunoreactivity was 63 min (RIA). However, HPLC revealed a more rapid disappearance (t1/2, 17 min) ofGRH(144)-NH2 ...
متن کاملThe enzymatic degradation of thymonucleic acid. I. The preparation of oligonucleotides.
This study constitutes the first phase of an investigation undertaken to develop a method for obtaining mononucleotides from the desoxyribonucleic acid of calf thymus, and concerns itself with the first step in the procedure, namely the production of oligonucleotides. Fischer, LehmannEchternacht, and Boettger (1) have studied the degradation of thymonucleic acid, prepared by Levene’s (2) method...
