This study has examined the properties of Crofer 22APU stainless steel produced by mechanical alloying for using as interconnect plates in solid oxide fuel cells.This alloy was produced by mixing the source powders and mechanical alloying for 40 hours. For creating a sample with high density, spark-plasma sintering was applied at 1100 °C and 50 Mpa stress for 10 minutes. To achieve the des...

metabolic syndrome is a chronic low-grade inflammation condition which is associated with central obesity, dyslipidemia, insulin resistance and hypertension. inflammation in metabolic syndrome is not only associated with elevated serum inflammatory markers, such as c-reactive protein (crp), but also, is associated with low-grade inflammation in adipose tissue and releasing of adipokines. higher...

Insulin resistance and hypertension are considered as prototypical "diseases of civilization" that are manifested in the modern environment as plentiful food and sedentary life. The human propensity for insulin resistance and hypertension is a product, at least in part, of our evolutionary history. Adaptation to ancient lifestyle characterized by a low sodium, low-calorie food supply and physic...

conclusions based on our findings, p. aerugionsa is a major causative agent of wound infections and amikacin could be considered as a more effective antibiotic for treatment of the burned patients. background nowadays, the treatment of burned patients is difficult because of the high frequency of infection with antibiotic resistance bacteria. objectives this study was conducted to evaluate the ...

Mutators may present an enhanced risk for the emergence of antibiotic resistance in bacteria during chemotherapy. Using Escherichia coli mutators as a model, we evaluated their ability to develop resistance to antibiotics routinely used for the treatment of urinary tract infections (UTIs). Under conditions that simulate therapeutic drug concentrations in humans, low-level resistance to trimetho...

Cutaneous leishmaniasis (CL) is an endemic parasitic disease of major health impact in many parts of the world and is caused by several species of the protozoan parasite Leishmania. Antimonial compounds (i.e glucantime and pentostam) are the first-line treatment for cutaneous leishmaniasis with emerging drug resistance as a problem. The control of Leishmania is further complicated by the emerge...

Because herbivores can move away from plants of low quality, induced resistance should affect the spatial distribution of herbivore damage (or herbivores) within or among plants. We used a spatially explicit simulation model and data from a field experiment to examine the effect of induced resistance on the distribution of herbivores and their damage among plants within a population. The model ...

    Background & Aim: The aim of this study was to compare air way resistance and dynamic compliance of tracheal tube and laryngeal tube in TIVA(Total Intravenous Anesthesia). Nowadays, low airway resistance and dynamic compliance improvement during the mechanical ventilation whether in ICU or during general anesthesia, especially in patients with pulmonary diseases, is a favorable purpose to c...

در تحقیق حاضر، مطالعه کاملی از آبکاری پالسی آلیاژ طلا ـ کبالت بر روی سوبسترای پوشیده شده با نیکل انجام شد. پارامترهای معین شده در این آبکاری پالسی گالوانو استاتیک شامل ؛ ارتفاع پالس (چگالی جریان)، زمان خاموشی پالس، زمان روشن بودن پالس و دمای حمام بودند که به منظور بدست آوردن یک لایه نانو ساختار مناسب با روش «یک عامل در زمان» بهینه سازی شدند. تاثیر متغیرهای پالسی برروی مورفولوژی، ریزساختار، ترکی...

Drug resistance and the distribution of R factors in Salmonella strains were surveyed using 1,980 strains isolated in Japan from 1955 to 1973. Resistances were mostly restricted to sulfanilamide (SA), tetracycline (TC), and streptomycin (SM), and combinations thereof. The demonstrated frequency of strains resistant to chloramphenicol (CM) was very low as compared with that in Escherichia coli a...
