در تحقیق حاضر عوامل محیطی(درونی و بیرونی) تأثیرگذار در عملکرد شرکتها و اتحادیههای تعاونی روستایی استان گیلان در قالب تحلیل سوات( (swot بررسی شدهاند. بر این اساس، نقاط قوت و ضعف، فرصتها و تهدیدهای پیشروی تعاونیها به کمک روش دلفای شناسایی و برپایة آن، راهبردهای مناسب جهت بهبود عملکرد تعاونیها ارائه شده است. جامعة آماری این پژوهش 174 شرکت و اتحادیة تعاون روستایی با حدود 1080 نفر شاغل را...
that act as posttranscriptional repressors by binding to the 3′UTR of target mRNAs (Lee et al. 1993; Reinhart et al. 2000; Bartel 2004; Kloosterman and Plasterk 2006). In animals, mature miRNAs are generated from a primary transcript (pri-miRNA) through sequential cleavage by nucleases belonging to the RNAse III family. Initially, Drosha cleaves the pri-miRNA and excises a stem-loop precursor (...
In the last decades researchers had focused on developing a vaccine against tick based on protective antigen. Recombinant vaccines based on concealed antigen from Boophilus microplus have been developed in Australia and Cuba by the name of TICKGARD and GAVAC (De La Fuente and Kocan, 2006). Further studies on this antigen have shown some extent of protection against other species (De Vos et al.,...
RNA interference (RNAi) is a term used to describe the sequence-specific suppression of genes, initiated by doublestranded RNA (dsRNA) oligonucleotides homologous to the sequence of the silenced gene (Hammond et al., 2001). RNAi was first observed in Caenorhabditis elegans as a response to exogenously introduced long double-stranded RNA (dsRNA) (Fire et al., 1998). While the mechanism of RNAi h...
1. introduction current statistical methods may be unable to accurately predict recurrence intervals of rare, large magnitude floods. the usual procedure involves extrapolation from gauged hydrological records documenting 30–40 year records of observed (normally small) floods to the estimation of the quantifies and recurrence intervals of very large, rare floods. this conventional approaches be...
For the linear bandit problem, we extend the analysis of algorithm CombEXP from Combes et al. [2015] to the high-probability case against adaptive adversaries, allowing actions to come from an arbitrary polytope. We prove a high-probability regret of O(T2/3) for time horizon T. While this bound is weaker than the optimal O( √ T) bound achieved by GeometricHedge in Bartlett et al. [2008], CombEX...
abstract this mixed method study examines whether there is any relationship among the variables of the study (job satisfaction, social capital and motivation). the researcher considered job satisfaction and social capital as independent variables; motivation is the dependent variable of the study. the researcher applied a questionnaire to assess each variable. to measure efl teachers’ job sati...
The problem of designing an output feedback compensator for any biased sinusoidal disturbance is considered. In this paper, we will develop the approach presented in (Marino et al., 2003). In (Marino et al., 2003) a compensator of order (2n+6) is proposed, which solves the posed problem by using the adaptive observers developed in (Marino and Tomei, 1995; Marino et al., 2001). This problem is s...
لپتوسپیروزیس یک بیماری حاد سپتی سمیک است که دارای اهمیت زئونوز می باشد. این بیماری انتشار جهانی داشته و پستانداران اهلی، وحشی و انسان را مبتلا می کند (levett 2001). لپتوسپیروزیس با زردی، کم خونی، هموگلوبینیوری، سپتی سمی، خونریزی های پتشی در بافتهای مختلف، نفریت بینابینی، سقط و ورم پستان در سنین مختلف همراه است (quinn et al. 2002). عامل آن یک نوع اسپیروکت به نام لپتوسپیرا است که در یک تقسیم بندی...
INTRODUCTION Genomic research provides an extraordinarily powerful new tool for solving applied problems. It can be extremely effective at resolving evolutionary relationships and can be used to extend earlier work defining the interrelationships of the plant-host strains of Xylella fastidiosa (see Hendson et al. 2001). Similarly, it can provide effective methods for identifying these host stra...
