مبدلهای ac/ac چند سطحی بر مبنای مدولهای تمام پل کاربردهای فراوانی در قدرتها و ولتاژهای بالا داشته و بعنوان نسل سوم کنترولرهای facts نیز مورد توجه قرار گرفته و تحقیقات دامنه داری دراین زمینه در جریان است. درهمین راستا، این مقاله روشی جدید برای مدولاسیون و کنترل اینگونه مبدلها ارایه می نماید بطوریکه کنترل مستقل ولتاژ خروجی بهمراه کنترل توان راکتیو در ورودی وخروجی امکان پذیر است. بعلاوه، این سیستم...
OBJECTIVES Comparative in vivo studies were carried out to determine the adsorption characteristics of amitriptyline (AMT) on activated charcoal (AC) and sodium polystyrene sulfonate (SPS). AC has been long used as gastric decontamination agent for tricyclic antidepressants and SPS has showed to be highly effective on in-vitro drugs adsorption. MATERIALS AND METHODS Sprague-Dawley male rats w...
BACKGROUND This study was aimed at evaluating whether or not patients with chronic type III acromioclavicular dislocation develop cervical spine pain and degenerative changes more frequently than normal subjects. METHODS The cervical spine of 34 patients with chronic type III AC dislocation was radiographically evaluated. Osteophytosis presence was registered and the narrowing of the interver...
conclusions moderate exercise for 8 weeks increased the ifn-γ and decreased the il-17 serum levels in the morphine-dependent rats. for this reason, this type of exercise can improve the function of the immune system during morphine withdrawal syndrome. results after 8 weeks of exercise, a significant increase was observed in the serum ifn-γ level in the ht group (251.17 ± 13.045) in comparison ...
We examined the physiological importance of bovine dietary proteins in rats fed diets prepared from bovine Achilles' tendons and arteries. Rats were fed for 4 weeks, with a 20% casein diet (CON), in comparison with two diets containing 15% casein and 5% of either bovine Achilles' tendon (AC) or artery (AR) protein preparations. The serum total cholesterol concentration and non-HDL-cholesterol l...
OBJECTIVE The purpose of this research was to detect cervical ripening with a new quantitative ultrasound technique. METHODS Cervices of 13 nonpregnant and 65 timed pregnant (days 15, 17, 19, 20, and 21 of pregnancy) Sprague Dawley rats were scanned ex vivo with a 70-MHz ultrasound transducer. Ultrasound scatterer property estimates (scatterer diameter [SD], acoustic concentration [AC], and s...
BACKGROUND Plasma exchange may be useful for treating patients with fulminant hepatic failure but during the procedure growth factors that are important for hepatic regeneration are discarded. Addition of a selective plasma filter to the plasmapheresis circuit could eliminate protein bound toxic substances and retain growth factors for hepatic regeneration. This process is called selective plas...
Background Regular par cipa on in physical ac vi es is important for all children to stay t and healthy. Children with cerebral palsy have reduced levels of physical ac vity, compared to typically developing children. The aim of the LEARN 2 MOVE 7-12 study is to improve physical ac vity by means of a physical ac vity s mula on program, consis ng of a lifestyle interven on and a tness traini...
The number skills of groups of 7 to 9 year old children with specific language impairment (SLI) attending mainstream or special schools are compared with an age and nonverbal reasoning matched group (AC), and a younger group matched on oral language comprehension. The SLI groups performed below the AC group on every skill. They also showed lower working memory functioning and had received lower...
alpha-Thalassemia is a synthesis hemoglobinopathy with a worldwide distribution. alpha-thalassemia-23.7kb (alpha-Thal23.7kb) was investigated by PCR and standard hematologic analysis techniques in 106 pregnant women - 53 heterozygous for hemoglobin (Hb) A and C (AC) and 53 homozygous for the normal Hb A (AA) with similar ages and race ancestry. Eleven (21%) of AC women were alpha-Thal23.7kb het...
