This paper presents an innovative solution for estimating the proximate parameters of coal beds from the well-logs. To implement the solution, the C# programming language was used. The data from four exploratory boreholes was used in a case study to express the method and determine its accuracy. Then two boreholes were selected as the reference, namely the boreholes with available well-logging ...
the extent to which written corrective feedback on linguistic errors can play a role in helping l2 writers improve the accuracy of their writing continues to be an issue of interest to researchers and teachers since truscott (1996) mounted a case for its abolition. while there is growing empirical evidence that written corrective feedback can successfully target some types of linguistic error (...
objective(s):althoughroutinely applied in assisted reproductive technology, human sperm cryopreservation is not a completely successful procedure. adverse effects of cryopreservation on the fertilization capacity, motility, morphology, and viability of spermatozoa have been proven; cryopreservation has also shown a role in sperm dna fragmentation and infertility. the post-thaw survival of sperm...
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
به منظور بررسی تاثیر شیرمادر در کاهش سپسیس دوره نوزادی مطالعه گذشته نگری به صورت مورد - شاهدی، طرح ریزی شد، 200 نوزاد بیمار با تشخیص بالینی سپسیس در گروه مورد و 200 نوزاد سالم در گروه شاهد مورد بررسی قرار گرفتند، فاکتورهای سن جنس وضعیت اقتصادی - اجتماعی بعنوان (matching factor) منظور شد. تحقیق در 15 بیمارستان تهران براساس 5 منطقه جغرافیایی تهران (شمال، جنوب ، غرب و مرکز) انجام گردید.
Granulocyte-colony stimulating factor (G-CSF) is a growth factor which stimulates proliferation, differentiation, and survival of hematopoietic progenitor cells. G-CSF is being used extensively in clinical practice to accelerate recovery of patients from neutropenia after cytotoxic therapy. However, growing evidences have suggested that G-CSF has important non-hematopoietic functions in central...
The immune response (I) region of the mouse 1-1-2 major histocompatibility complex regulates interaction between thymus-derived (T) and bone-marrow-derived (B) lympho-cytes that result in antibody synthesis (reviewed in references I and 2). Immune response (Ix) genes control specific immune responses to various synthetic and native antigens (3) but their cellular site of action (T cells and/or ...
Squirrel monkeys were significantly depleted of complement by a nontoxic protein constituent of cobra venom, and the influence of cobra factor (CoF) treatment on the course of Escherichia coli bacteremia was studied. Striking neutropenia occurred rapidly in control animals while the rate of occurrence of neutropenia was 20 to 30 times slower in the CoF-treated animals, suggesting that the E. co...
Abstract: Problems such as the difficulty of the selection of processing parameters and the large quantity of experimental work exist in the morphological evolutions of Semisolid Metal (SSM) processing. In order to deal with these existing problems, and to identify the effect of the processing parameters, (i.e. shearing rate-time-temperature) combinations on particle size and shape factor, ...
effect of gibberellic acid on marigold (calendula officinalis l.) was evaluated in a pot culture experiment. a factorial experiment based on completely randomized design including 12 treatments and four replications was carried out. main factor was foliar application stages (first, second and third) and sub factor included different concentrations of ga3 (0, 50, 150 and 250 mg l-1). results sho...
