there are many techniques to knock out directed genes in bacteria, some of which have been described in salmonella species. in this study, a combination of soeing pcr method and the λ red disruption system were used to disrupt phop gene in wild type and standard strains of salmonella typhimurium. three standards pcr and one fusion pcr reactions were performed to construct a linear dna including...

باکتری شیگلا و سویه های اشرشیا کلی مهاجم روده ای (eiec) جزء خانواده با کتریهای گرم منفی و عامل مسری ترین اسهال باسیلی (شیگلوز) می باشند. ژن virg یکی از  فاکتور های ضروری در آسیب زایی باکتری شیگلا است. پروتئین رمزگذاری شده توسط این ژن، بر روی غشای خارجی (om) شیگلا قرار گرفته و به خانواده پروتئینهای خود منتقل شونده at (autotrnasporter) خارج سلولی در باکتریهای گرم منفی تعلق دارد. یکی از روشهای ساخ...

This paper presents both, the design and the development of a monitoring and control system via web for a closed microalgae crop and the results that were gotten using the strain Haematococcus pluvialis. The research was done at Sabana University (Colombia) and it aims to quantify the kinetic growth associated to the increment of biomass and the development of red pigment inside the cells when ...

در این پایان نامه مسأله وجود وعدم وجود طرح های فوق ساده را بررسی می کنیم. یک طرح بلوکی غیرکامل متعادل با پارامترهای k، v, λ, (به طور خلاصهv,k,λ)-bibd ‎))عبارت است از جفت ‎(v,b)‎, که v‎مجموعه ی v‎عضوی و ‎ b‎خانواده ای از زیر مجموعه های k عضوی از v (به نام بلوک ها) است, که هر جفت از اعضای v‎ در دقیقاً λ بلوک b ظاهر می شود. یک طرح بلوکی را ساده گوییم, در صورتی که در آن بلوک تکراری وجود نداشته باش...

First cohomology groups of finite groups with nontrivial irreducible coefficients have been useful in several geometric and arithmetic contexts, including Wiles’s famous paper (1995). Internal to group theory, 1-cohomology plays a role in the general theory of maximal subgroups of finite groups, as developed by Aschbacher and Scott (1985).One can pass to the case where the group acts faithfully...
