This paper describes modeling and simulation for the growth and dissolution of oxygen precipitates in Czochralski silicon(CZ) wafers during heat treatment. Growth and dissolution rates arc newly derived and inserted into a set of chemical rate equations(CILEs) and a Fokkor-Planck equation(FPE). Annealing ambients and surface conditions are taken into account for solving continuity equations in ...

Background: Considering natural thermal stability, Geobacillus stearothermophilus amylase and Cel5E from Clostridium thermocellum are good candidates for industrial applications. To be compatible with the industrial applications, this enzyme should be stable in the high temperatures, so any improvement in their thermal stability is valuable.Objectives: Us...

background: eukaryotic proteins generally have signal peptides, which are not only crucial for their secretion efficiencies but are important for their expression levels. the coagulation factor ix (fix) is a glycoprotein that plays a fundamental role in a blood coagulation pathway. reduced levels or dysfunctional fix are associated with hemophilia b. to improve the hfix secretion efficiency in ...

Introduction: Acinetobacter baumannii is associated with hospital-acquired infections. Outer membrane protein A of A.baumannii (AbOmpA) is a well-characterized virulence factor which has important roles in pathogenesis of this bacterium. Methods: Based on our PCR-sequencing of ompA gene in the clinical isolates, AbOmpA protein can be categorized into two types, named here type-1 and type-2. We ...

An increasing number of studies have demonstrated the effectiveness of flagellin (FliC) as an adjuvant. In this study, FliC(s) from Salmonella enterica serovar Typhimurium, Pseudomonas aeruginosa, and Escherichia coli were compared. In silico studies were designed to determine physicochemical parameters of FliC from different bacteria. The fliC gene corresponding to best model was amplified, cl...

objective: druggability of a target protein depends on the interacting micro-environment between the target protein and drugs. therefore, a precise knowledge of the interacting micro-environment between the target protein and drugs is requisite for drug discovery process. to understand such micro-environment, we performed in silico interaction analysis between a human target protein, dipeptidyl...
