A bacteriological investigation performed on the biopsies of 1 30 patients with gastrointestinal disorders at the GI section of Imam Khomeini hospital concluded in the isolation of 100 cases of Helicobacler pylori. The antibacterial effects of bismuth salts alone and in synergy with tetracycline and metronidazole were evaluated on the basis of disc diffusion method on 5 randomly selected pu...
Introduction Many infectious diseases are endemic in a population. In other words they present for several years. Suppose that the population size is constant and the population is uniform. In the SIR model the population is divided into three disjoint classes which change with time t and let , and be the fractions of the population that susceptible, infectious and removed, respectively. This...
بررسی تنوع ژنتیکی ژنوتیپهای بومی پیاز ایرانی در مقایسه با انواع خارجی چکیده: برنامه های اصلاحی گیاهان بر اساس تنوع و انتخاب صفات برتر کمی و کیفی صورت می گیرد. لذا، ارزیابی تنوع ژنتیکی، اولین مرحله در برنامه های اصلاحی است. در این راستا، استفاده از روش های جدید مطالعهی تنوع ژنتیکی ضروری به نظر می رسد. در این بررسی تعیین تنوع ژنتیکی سیزده ژنوتیپ پیاز ایرانی در مقایسه با دو ژنوتیپ خارجی با است...
Seed coat color as a perfect and simple index is effective in water absorption, seed dormancy and germination. The mustard plant produces seeds with different coat color. So, in order to investigate the effect of seed coat color on germination rate, the percentage of germination and dormancy of Mustard (Sinapis arvensis L.) seeds an experiment was carried out based on a completely randomized de...
BACKGROUND Exercise-stress electrocardiography (ECG) is initially recommended for the diagnosis of coronary artery disease. But its value has been questioned in women because of suboptimal diagnostic accuracy. Stress echocardiography had been reported to have comparable test accuracy in women. But the data comparing the diagnostic accuracy of exercise-stress ECG and stress echocardiography dire...
in the present study, five modeling approaches of ra, mlp, mnn, gff, and canfis were applied so as to estimate the radial overcut values in electrochemical drilling process. for these models, four input variables, namely electrolyte concentration, voltage, initial machining gap, and tool feed rate, were selected. the developed models were evaluated in terms of their prediction capability with m...
