This study aimed to assess the frequency, severity and its predictors among who are An Analytical cross-sectional was done 233 people chemotherapy in Cancer Hospital. Convenience sampling...
شکل¬دهی بدست آمده در این پژوهش برای پیش¬بینی شکل¬پذیری قطعه¬های صنعتی قابل استفاده است. تولید محصولات پیچیده صنعتی از لوله¬های فلزی با هدف افزایش نسبت استحکام به وزن سازه¬ها و خصوصاً کاهش مصرف سوخت وسایل نقلیه در سال¬های اخیر مورد توجه صنعتگران قرار گرفته است. در این راستا یکی از فرایندهای جدید مورد استفاده، روش¬های شکل¬دهی با سیال (هیدروفرمینگ) می¬باشد. پارگی در فرایندهای شکل¬دهی ورق¬ها و لوله...
human interferon β (inf-β) is a member of cytokines family which different studies have shown its immunomodulatory and antiviral activities. in this study an expression vector was designed and constructed for expression of human inf-β-1b either in shake flasks and bench top bioreactor. the designed vector was constructed based upon pet-25b(+) with t7 promoter. recombinant human beta interferon ...

Researchers treated seed technology and crop yield as exogenous, thereby generating bias estimates. In practice, increases it’s stimulated by social capital other factors. This paper develops a choice model of maize-seed exogenously, then tested corrected for causality. A multistage sampling procedure was adopted using seven Agricultural Development Programme zones drawn from purposively select...
background: approximately 180 mutations have been described in β-thalassemia worldwide with specific spectrum in each ethnic population. this study determines the spectrum and the frequency of β-thalassemia mutations in patients with β-thalassemia trait and sickle cell-β-thalassemia. methods: fifteen compound heterozygous sickle cell thalassemia (sct) and 23 β-thalassemia trait patients were ...
The production of β-lactamase enzymes is the main mechanism of resistance to β-lactam antibiotics in gramnegative bacilli. Therefore, it is important to identify the β-lactamases-producing bacteria for the treatment of caused infections. This article aimed to review the recent literature and guidelines regarding phenotypic detection of β-lactamases in common gram-negative bacilli in clinical sa...
thermodynamic study on the interaction of β-cd with poly ethylene oxide and poly acrylic acid was performed by isothermal titration calorimetry at 298k. when β-cd is added to the interpolymer complex, competition is created between host-guest and hydrogen bond. enthalpy of interaction between the β-cd and interpolymer complex was calculated using the extended solvation theory. p=1 shows that wi...
