از انجایی که استفاده از اتصالات ساده و مفصلی یکی از راه های بهینه کردن اقتصادی سازه های فولادی می باشد محققین در سال های اخیر استفاده از دیوار برشی را در این نوع سازه ها مورد بررسی قرارد داده اند. این نوع سیستم ها با توجه به سختی زیاد دیوار برشی عملکرد بسیار بهتری نسبت به سیستم بادبندی در نیروهای لرزه ای نشان می دهد. با توجه به اینکه روش تحلیل دینامیکی افزایشی(ida) به دلیل نداشتن مشکل الگوی بار...
Background: Diabetes Mellitus (DM) has become a major health problem worldwide. American Diabetes Association has considered HbA1C levels ≤ 6.5 % as the prime target for glycemic control and as a diagnostic criterion for DM. Anemia is common in DM (8-66%). Studies on alteration of HbA1C in IDA have conflicting results. Objectives: To identify and compare the effect of IDA on HbA1C levels among ...
دراین پایان نامه یک روش تحلیل غیر خطی ارائه شده است که به کمک آن می توان یک سازه را براساس عملکرد و رفتار مورد انتظار طراحی کرد. در این الگو از تحلیل دینامیکی غیر خطی افزایشی استفاده شده است که نسبت به انواع دیگر تحلیل بسیار دقیق تر می باشد و می تواند دید خوبی از ظرفیت سازه را فراهم آورد و موقعیت اولین نقطه تسلیم را در اختیار ما قرار دهد.همچنین در یک ساختمان آسیب دیده که خصوصیات دینامیکی آن بعد...
This study aimed to examine the prognostic significance of pre-existing iron deficiency anemia (IDA) and the benefits of early colonoscopy in patients with colon cancer, since these have not been clearly established to date. Using the Taiwanese National Health Insurance Research Database, we retrieved and retrospectively reviewed the records of patients aged ≥ 55 years who were diagnosed with c...
background: the iron deficiency anemia (ida) is a common cause of referral to medical departments. chronic gastrointestinal (gi) blood loss is important cause of ida and also an alarming sign of serious underlying disease. the information concerning ideal evaluation of the gastrointestinal tract in patients with the ida is scant. we designed a prospective study to determine the frequency of gi ...
Transposition tables are a well-known method for pruning duplicates in heuristic search. This paper presents a detailed analysis of transposition tables for IDA*. We show that some straightforward implementations of IDA* with transposition tables (IDA*+TT) can result in suboptimal solutions being returned. Furthermore, straightforward implementations of IDA*+TT are not complete. We identify sev...
OBJECTIVES The purpose of this study was to evaluate the rate of, and risk factors for, subsequent impaired driving activity (IDA) in a cohort of injured passengers who were treated for injuries in a Canadian trauma center. METHODS We studied adult passengers who were occupants in vehicles involved in motor vehicle crashes (MVCs) and either included in the British Columbia (BC) trauma registr...
Introduction: Iron deficiency (ID) is the most prevalent nutritional disorder in the world. The prevalence of iron deficiency anemia (IDA) is about 9% in toddlers, 9-11% in adolescent girls and less than 1% in teenage boys. IDA presents when there is not sufficient iron for haemoglobin synthesis. In particular it has negative effects on the behavior, cognitive performance, immune system and phy...
BACKGROUND Seroepidemiological and clinical studies suggest that Helicobacter pylori may cause iron deficiency anaemia (IDA) in the absence of peptic lesions by undefined mechanisms, which still remain to be fully elucidated. Gastric acidity and ascorbic acid (AA) promote iron absorption. AA is lowered in the presence of H pylori infection. H pylori can cause atrophic body gastritis with achlor...
