the performance of dual-layer multiple tuned mass dampers (dl-mtmd) with uniformly distributed natural frequencies is investigated. the dl-mtmd consists of one large tuned mass damper (l-tmd) and an arbitrary number of small tuned mass dampers (s-tmd). the primary structure is represented as a single degree-of-freedom system which corresponds to a specific vibration mode to be controlled in a r...

purpose the purpose of this investigation was to compare a practical measurement of fat free mass index (ffmi) from bioelectrical impedance analysis (bia) to the dual energy x-ray absorptiometry (dexa) value in collegiate athletes. methods thirty-three male baseball players and 16 female gymnasts volunteered to participate in this study during their respective pre-season. subjects visited the l...

background: chronic obstructive pulmonary disease (copd) is considered a major public health problem in the world. weight loss, muscle and fat mass depletion are common nutritional problems in copd patients and are determinant factors in pul­monary function, health status, disability and mortality. in the present study, we assessed nutritional status in copd pa­tients. methods: this cross-secti...

proteins are fundamental components of cells which mediate many essential biological processes. proteomics is a rapidly growing field for the study of proteome, the protein complement expressed by the genome of an organism or cell type. the large-scale analysis of proteins leads to a more comprehensive view of molecular and cellular pathways that improves the overall understanding of the comple...

testicular schwannoma is a very rare benign scrotal tumor. it is a painless mass, but sometimes referred because of pain or sensory losses. tumor markers are normal and radical orchidectomy is its best treatment. here we present an unusual case of intrascrotal schwannoma in a 57 year old man, with a review of the literature.

inguinal mass is a common clinical finding or even symptom in childhood while the most common diagnosis is inguinal hernia that may proceed with prompt surgical but there are a vast variety of different entities that may manifest as an inguinal mass and in some instances, surgical approach is not indicated or may need further preoperative assessments to determine a correct therapeutic plan. in ...

background: molecular epidemiology of measles virus (mv) is important, not only to measure the success of measles vaccination programs but also to monitor the circulation and elimination of the virus worldwide. in this study, we compared mv obtained from patients before the 2003 mass vaccination mr campaign and viruses detected after 2003 until 2008 in iran. methods: the nucleoprotein (n) gene ...

background and objective: mediastinal masses in children are a heterogenous group of asymptomatic potentially life-threatening congenital, infectious, or neoplastic lesions that present complex diagnostic and therapeutic dilemmas. materials and methods: the clinical and laboratory features of 65 patients who had open biopsies in ali-asghar hospital over 11 years were reviewed. results: seventy-...
