saluk mount is selected for devonian biostratigraphy. this area located at southwest of bojnurd. in this study three sections are selected and two sections, chahar-borj and tabar sections with a thickness of 650 m, which consist mainly of calcareous sediments was studied in detailed but third section, qelli section, with a thickness of about 450m which consist mainly of sandstone and evaporates...
this research has been taken among the students of high school in karaj city during the years 1391 and 1392. this is a survey research and data gathering is through questionnaires. studying the “an analysis of students’ tendency toward non-native reference groups in karaj”. the questionnaire was distributed among 260 of these students who were chosen through multi step cluster sampling. conside...
Background and Aims: Viroids are smallest known plant pathogens and cause several economically significant diseases. Until recently, viroid detection relied mainly on biological tests and indexing. Today various diagnostic techniques such as nucleic acid hybridization, southern blot and reverse transcription coupled with polymerase chain reaction (RT-PCR) are being used for detection and diag...
The reverse transcription polymerase chain reaction (RT-PCR), reverse passive haemagglutination assay (RPHA) and agar gel precipitation test (AGPT) were compared for the detection of infectious bursal disease virus (IBDV) in various organs of experimentally infected broilers. RT-PCR and RPHA required a time of 8 and 1 hour, respectively, whereas AGPT showed precipitation reaction at least after...
Enteroviruses are the causative agents of a number of diseases in humans. Group B coxsackieviruses are believed to be the most common viral agents responsible for human heart disease. Genomic data of enteroviruses has allowed developing new molecular approaches such as Nucleic Acid Sequence Based Amplification (NASBA) for detection of such viruses. In this study, coxsackievirus B3 (CVB3) was de...
A variety of factors that influence real-time reverse transcriptase (RT)-PCR results were examined. Realtime reaction volumes can be decreased from the manufacturers suggested volumes (50μl) to as little as 5μl. Errors introduced through volume handlings can be significantly mitigated through the use of electronic pipettes. Random hexamers are compared against the use of a specific reverse tran...
abstract:assume that y is a banach space such that r(y ) ? 2, where r(.) is garc?a-falset’s coefficient. and x is a banach space which can be continuously embedded in y . we prove that x can be renormed to satisfy the weak fixed point property (w-fpp). on the other hand, assume that k is a scattered compact topological space such that k(!) = ? ; and c(k) is the space of all real continuous ...
nowadays enhancing critical thinking in learners is considered one of the foreign language teachers’ tasks due to its high position in foreign language classrooms. when it comes to selecting materials for language classrooms, there are obviously some criteria that teachers should apply. the present study aimed at a critical thinking based analysis of ten picture story books and ten folktales th...
the main objective in sampling is to select a sample from a population in order to estimate some unknown population parameter, usually a total or a mean of some interesting variable. a simple way to take a sample of size n is to let all the possible samples have the same probability of being selected. this is called simple random sampling and then all units have the same probability of being ch...
background influenza type a (h1n1) causes an epidemic disease, resulting in thousands of deaths throughout the world. objectives our aim was comparing the efficacy of two different methods in isolating the influenza (h1n1) virus including cell culture and real-time pcr in tabriz and suburbs. patients and methods of throat swab samples, 220 were collected in viral transport medium (vtm) from pat...
