Four hundred isolates of Ascochyta rabiei (Pass.) Lab. collected from different parts of the country, such as Zarivar Marivan Lake in Kordestan Province Shabestar and Khosroshahr in Eastern Azarbaigan Province Serow, Bokan and Shahindeg in Western Azarbaigan Province Mashhad and Ilam were used in this experiment. These isolates showed little differences in their cultural and morphological cha...
abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
AIM Subclinical mastitis in bovines is mainly responsible for the huge economic loss of the dairy farmers, of which Pseudomonas aeruginosa is one of the causative agents. The study was aimed at a screening of suspected milk samples from different cattle farms of West Bengal for detection and confirmation of P. aeruginosa strains followed by their characterization. MATERIALS AND METHODS Around...
plagiarism in esl/efl learning contexts has been established as a dynamic and multi-layered phenomenon and has become a topic engaging many researchers in a heated debate in recent years. comparisons of student-generated texts with their source texts have shown that students rely on source texts in their writings and copying is a major strategy used by both l1 and l2 writers. in our country a...
abstract this study was carried out of identify the tomatinase extracellular enzyme in fusarium oxysporum f.sp. lycopersici race1 the casual agent of wilting in tomato. 20 isolates of fusarium oxysporum were recovered from infected roots,crown and stems of tomato plants collected from fields in major tomato producing areas in northern and razavi khorasan province during 2009-2010 . pathogenicit...
recent years have witnessed an increased attention to form focused instruction and consciousness raising activities (ellis, 2002; doughty & williams, 1998) on the one hand and extensive and meaningful exposure to the target language (klapper & rees, 2003; day & bamford, 1998) on the other. due to significance attributed to above mentioned issues by scholars, this study attempted to bridge them ...
Introduction: The Enterococcus faecalis (E. faecalis) is the one of the pathogenic bacteria that become famous and considerable in the recent years. Here we tried to do typing the E. faecalis isolates to provide advantageous information that can help us to understand epidemiological communication between the E. faecalis isolates. Materials and methods: One hundred E. faecalis were isolated fr...
this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...
Colibacillosis caused by E.coli is one of the most common illnesses in commercial chickens and induce high financial losses in the poultry industry due to morbidity, mortality and antibiotic expenses because of overuses. E.coli can mostly cause disease as a secondary or opportunistic pathogen, while certain strains with specific virulence factors even as primary pathogen can cause colibacillosi...
BACKGROUND & OBJECTIVES Biological control of sandflies using entomopathogenic fungi is a possible alternative to the expensive synthetic chemical control. It is potentially sustainable, less hazardous, and relatively inexpensive and merits further investigations. The objective of this study was to identify the most pathogenic fungal isolate(s) to sandflies in the laboratory. METHODS Isolates...
