An indirect immunodot assay with rabbit antibodies raised against purified heat-stable enterotoxin type b (STb) and with a Western blotting (immunoblotting) detection system (ECL; Amersham International plc, Amersham, United Kingdom) was developed for the detection of STb toxin. Culture supernatants of 62 Escherichia coli isolates from pigs with diarrhea were blotted onto nitrocellulose and inc...
the present research was conducted to explore the effect of employing two language teaching approaches, i.e. schema-based instruction (sbi) and translation-based instruction (tbi), on vocabulary knowledge, structure and reading comprehension ability of forty one female students learning english in grade one senior high school in rivash, kuhsorkh, iran. while sbi focuses on schemata, i.e. words ...
There are at least two classes of Escherichia coli heat-stable enterotoxins, STa and STb. Unlike STa, which is active in suckling mice and piglets, STb is inactive in suckling mice but active in piglets and older, weaned pigs. This study examined the activity of STb in several animals and its effect on intestinal histology and cyclic GMP levels in intestinal mucosal cells. STb did not cause flu...
due to extraordinary large amount of information and daily sharp increasing claimant for ui benefits and because of serious constraint of financial barriers, the importance of handling fraud detection in order to discover, control and predict fraudulent claims is inevitable. we use the most appropriate data mining methodology, methods, techniques and tools to extract knowledge or insights from ...
abstract this study set out to compare the effect of modality of presentation (subtitled vs. auditory) in the comprehension of verbal content of documentary films among iranian efl students. to this end, (30 male 30 female) students were chosen from two schools. after their homogeneity was established, the students attended the listening sessions to watch five documentary films over t...
bekenstein and hawking by introducing temperature and every black hole has entropy and using the first law of thermodynamic for black holes showed that this entropy changes with the event horizon surface. bekenstein and hawking entropy equation is valid for the black holes obeying einstein general relativity theory. however, from one side einstein relativity in some cases fails to explain expe...
Super liquid-repellent layers need to have a high impalement pressure and high contact angles, in particular a high apparent receding contact angle. Here, we demonstrate that to achieve both, the features constituting the layer should be as small as possible. Therefore, two models for super liquid-repellent layers are theoretically analyzed: A superhydrophobic layer consisting of an array of cy...
burnout is a response to the chronic work stress which is prevalent mostly among the people who do people job, like teaching. the purpose of this study was to develop a valid and reliable instrument that can measure burnout in foreign language teachers. although some widely used instruments were developed before which measured burnout in teachers, a specific instrument which include specific sy...
2 microns DNA isolated from industrial Saccharomyces cerevisiae yeasts exhibited extensive restriction fragment length polymorphisms. At least five 2 microns species were identified from eleven [cir+] strains. Southern hybridization mapped restriction fragment length polymorphisms at STB, a cis-acting locus essential for plasmid partitioning. Some 2 microns variants (e.g., 4110-2 microns and 41...
the world wide web becomes very popular recently and plays an influential role in english learning. by burgeoning role of source-based writing as partial fulfillment of tefl courses and vast use of the internet, lack of empirical studies to explore these areas is obvious. this study aimed to explore the effect of the amount of familiarity with the web (internet literacy) on junior english stude...
