cladophora and enteromorpha are the filamentous green-algal genuses that have a widespread distribution in caspian sea coast. the aim of this study was to assess the antimicrobial activities of cladophora and enteromorpha in south of caspian sea. antibacterial activities of hydroalcoholic extracts of five different gram negative and positive bacteria including staphylococcus aureus, bacillus su...
To promote the use of oral rehydration therapy (ORT), a training programme was launched by The Pakistan National Programme for Control of Diarrhoeal Disease (CDD) by establishing the Diarrhoea Training Units (DTUs). Physicians trained at DTU were designated to establish functioning oral rehydration therapy (ORT) corners at their health centres and train health workers in delivery of facilities ...
in chapter 1, charactrizations of fragmentability, which are obtained by namioka (37), ribarska (45) and kenderov-moors (32), are given. also the connection between fragmentability and its variants and other topics in banach spaces such as analytic space, the radone-nikodym property, differentiability of convex functions, kadec renorming are discussed. in chapter 2, we use game characterization...
چکیده کنه تارتن دو لکه ای tetranychus urticae koch یکی از چندخوارترین آفات شناخته شده محصولات کشاورزی دنیا به حساب می آید. در این بررسی جمعیت تخم و مراحل فعال این کنه در شرایط آلودگی طبیعی و مصنوعی در برگ های 8 رقم لوبیا در سال 1392 در گلخانه و مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه ارومیه موردمطالعه قرار گرفت. آزمایش به صورت طرح کاملاً تصادفی برای شرایط مزرعه در10 تکرار و برای شرایط گلخانه ای...
Recent results show that a nonsmooth time invariant feedback control law can be used to stabilize an axi symmetric rigid body using only two control torques to the zero equilibrium This method however may require a signi cant amount of control e ort especially for initial conditions close to an equilibrium manifold In this paper we propose a modi cation of the previous control law which reduces...
The trajectory tracking problem for multivariable linear systems is considered. Two different techniques are examined: the output regulation theory (ORT) and the flatness based tracking (FBT). ORT and FBT are two different approaches to solve the tracking problem, and both methods have different restrictions. The tracking controller of the ORT furthermore depends on the solution of the so-calle...
Results currently available clearly indicate that the metabolite-activated protein kinase-mediated phosphorylation of Ser-46 in HPr plays a key role in catabolite repression and the control of inducer levels in low-GC Gram-positive bacteria. This protein kinase is not found in enteric bacteria such as E. coli and Salmonella typhimurium where an entirely different PTS-mediated regulatory mechani...
today the image of a permanent skeletal space of cities affected by some forces or mechanisms is put in time with social-economic development and while imposes a new face and perspective to physical anatomy of cities, and prepares field to changes in content and social- economic structures of cities too. simultaneously with quitting villages in order to settle in cities by villagers, the phen...
introduction: some bacteria are capable of entering the plant as endophytes that do not cause harm and could establish a mutualistic association with host plants. endophytic bacteria are bacteria that live in plant tissues without doing substantive harm. they enter plant tissue primarily through different plant zones. both gram-positive and gram-negative bacteria have been isolated from several...
Introduction: In recent years, food manufacturers have taken a lot of attention to the use of natural preservatives instead of chemical preservatives in their products, which has led consumers to prefer to use processed food without preservatives or even with natural preservatives. The aim of the present study was to investigate the antibacterial effect of ethanolic extract of Biebersteinia mul...
