Blocking filtration laws consist of four different mechanisms: complete blocking, standard intermediate and cake filtration. for describing both the pore blocking formation have been extensively employed over past several decades to evaluate increase in resistance with progress field classical particulate In recent years, become widely used also membrane such as microfiltration ultrafiltration colloids. This paper gives an overview developments equations under constant pressure rate...

A modified triester method has been developed for the synthesis of oligonucleotides starting from mononucleosides as more economical materials. pentadecanucleotide successfully prepared.
Psilocin (3-[2-(dimethylamino)ethyl]-1H-indol-4-ol) is a hallucinogenic component of the Mexican mushroom Psilocybe mexicana and skeletal serotonin (5-HT) analogue. active metabolite psilocybin (3-[2-(dimethylamino)ethyl]-1H-indol-4-yl dihydrogen phosphate). In present study, we examined effects systemically administered psilocin on extracellular dopamine 5-HT concentrations in ventral tegmental area (VTA), nucleus accumbens, medial prefrontal cortex dopaminergic pathway awake rats using...
Biobleaching of hardwood unbleached kraft pulp (UKP) by Phanerochaete chrysosporium and Trametes versicolor was studied in the solid-state fermentation system with different culture media. In this low-nitrogen high-carbon medium, brightness increased 15 30 points after 5 days treatment T. P. chrysosporium, respectively, kappa number decreased increasing brightness. A comparison manganese peroxidase (MnP), lignin (LiP), laccase activities assayed using fungus-treated filtrate homogenizing...
We have synthesized the deoxyribooligonucleotide fragments, constituting sequence of lac operator Escherichia coli.
The synthesis and in vitro anti-HIV activity of two new racemic nucleoside analogues are described; namely, 9-[c-4,t-5-bis(hydroxymethyl)cyclopent-2-en-r-1-yl]-9H-adenine (12) its guanine analogue 18. While the latter (18) showed no activity, therapeutic index former was 200 comparable to that (400) carbovir. One enantiomer 12 may be viewed as an carbocyclic oxetanocin other Hence, these results indicate one or both individual enantiomers could serve candidates lead compounds for development...
The 21-nucleotide-long duplex DNA constituting the lactose operator sequence of E. coli has been synthesized by both chemical and enzymatic methods. synthetic essential feature as seen its binding to repressor. fragment repressor is specific because it inhibited inducing ligand isopropyl-beta-D-thiogalactoside. Thus, now possible show that a chemically oligodeoxynucleotide can be specifically recognized natural regulatory protein.
Upward dead-end filtration tests accompanied with a sudden reduction in the cake surface during course of are proposed order to determine properties filter formed microfiltration oil-in-water (O/W) emulsion. Both upward and downward were conducted under constant pressure conditions by using having its area, characteristics between two compared. Consequently, it was found that rate much higher than as result exfoliation which occurred filtration, leading lower specific resistance. Moreover,...
The synthesis of lactose-operator gene fragments have been achieved by the improved triester methodology and new phosphorylating condensing reagents.
Abstract The gradual decrease in the filtration flux rate with time, which occurred due to capture of solid particles and/or organic substances onto surfaces pores a thin filter medium, was measured constant‐pressure both pool water and pond water.
