the aim of this paper is to generalize thenotion of pseudo-almost valuation domains to arbitrary commutative rings. it is shown that the classes of chained rings and pseudo-valuation rings are properly contained in the class of pseudo-almost valuation rings; also the class of pseudo-almost valuation rings is properly contained in the class of quasi-local rings with linearly ordere...
تصویر برداری از مغز به دو گونه می باشد: تصویربرداری ساختاری و تصویربرداری عملکردی. در تصویر برداری ساختاری شاهد اطلاعاتی مربوط به آناتومیک و ساختار مغز هستیم. در حالی که تصویر عملکردی بیانگر فعالیت مغز در نواحی گوناگون می باشد. تفسیر جداگانه ی این تصویر ها برای پزشک امری دشوار است و از طرفی تصاویر عملکردی مثل اسپکت از رزولوشن پایینی برخوردارند در حالی که تصویر ساختاری مثل ام آر آی رزولوشن مکانی...
آنزیم¬های کایمری از جمله پروتئین¬های مهندسی شده می¬باشند که از تغییر در ساختار آنزیم¬ها بدست می¬آیند. آنزیم¬های کیتینازی بدلیل توانایی در تجزیه ترکیبات کیتینی، در تولید پروتوپلاست قارچی، تبدیل زیستی shellfish waste به بخش های تک جزئی، تولید الیگوساکاریدها و کنترل قارچ¬های بیماریزا حائز اهمیت می-باشند. در این تحقیق پس از تکثیر ناحیه (chitin binding domain) chbd کیتینازb باکتری serratia marcescen...
background: dengue is a global arboviral threat to humans; causing 390 million infections per year. the availability of safe and effective tetravalent dengue vaccine is a global requirement to prevent epidemics, morbidity, and mortality associated with it. methods: five experimental groups (6 mice per group) each of 5-week-old balb/c mice were immunized with vaccine and placebo (empty plasmid) ...
this research aims to compare the capabilities of a thesaurus and an ontology for representation of domain knowledge. this is the first to focus on the construction of an ontology in library and information science (lis), in the domain of indexing and in persian language. the research also develops the methodology of ontology construction by implementing domain analysis methodology. the present...
The titled problem of coupled thermoelasticity for porous structure has been solved with an instantaneous heat source acting on a plane area in an unbounded medium. The basic equations of thermoelasticity, after being converted into a one-dimensional form, have been written in the form of a vector-matrix differential equation and solved by the eigenvalue approach for the field variables in the ...
The domains of mystic topics in related text greatly expanded in the late 6th and 7th centuries (A.H). This expansion led to the use of new lexical items for the expression of new concepts. One domain is the lexical domain used for the description of different levels of existence. Letter (harf), word (kalameh), discourse (kalām), book (ketāb), pen (qalam), etc. are parts of this domain. This wo...
conclusions although previous studies have shown that a-g transition mutations in 23 srrna gene (domain v) are the main reason for the occurrence of high level macrolides resistance in b. pertussis, however, the mentioned single nucleotide polymorphisms (snps) have not been detected in our resistant strain. this is the first report of high level macrolide resistant b. pertussis, without snps 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 ...
