The use of the social media can influence body image concerns, social isolation, and social mood. The purpose of the present study is to assess body image concerns, social isolation, and mood based on the amount of social media use. Method: This study has been conduc...

Semi-active base isolation system has been proposed mainly to mitigate the base drift of isolated structures while in most cases, its application causes the maximum acceleration of superstructure to be increased. In this paper, designing optimal semi-active base isolation system composed of linear base isolation system with low damping and magneto-rheological (MR) damper has been studied for co...

in this paper a new isolating system is introduced for short to mid-rise buildings. in comparison to conventional systems such as lrb and hrb, the proposed system has the advantage of no need to cutting edge technology and has low manufacturing cost. this system is made up of two orthogonal pairs of pillow-shaped rollers that are located between flat bed and plates. by using this system in two ...

conclusions this report presents a new method for lung isolation in specific cases and in the absence of certain equipment. case presentation a 41-year-old woman with a history of pharyngo-laryngo-oesophagectomy (plo) and tracheostomy was a candidate for thoracic duct ligation because of chylothorax. since the patient had tracheostmy stomal stenosis, two cuffed tracheal tubes (internal diameter...

residual lignin of wood after mwl isolation was dissolved with 1-butyl-3-methylimidazolium chloride ionic liquid. chemical structure of isolated mwl from poplar wood (popolus deltiodes) and dissolved residual lignin were characterized with gas chromatography and 1d, 2d nmr techniques. analytical results showed that  popolus deltoides wood has more 4-(3-hydroxy-1-propenyl)-2-methoxy phenol units...

ornithobacterium rhinotracheale (ort) has been identified as one of the respiratory bacterial pathogens in turkey and chicken flocks. four live birds displaying severe torticollis were submitted from a 13-week-old commercial broiler breeder chicken flock located in mazandaran province. these birds were suspected to pasteurellosis by the farm veterinarian. no other marked gross lesion except em...

scorpion venoms contain of variety of peptides toxic to mammals ، insects and crustaceans. toxic peptides are the main factors in scorpion venom causing toxicity, (their amount being 1-3%of total venom.). most of the scorpion toxins have been isolated from the venoms of scorpions in the family buthidae. the scorpion buthotus schach belonging to the buthidae family is widely found in the western...

background: in cancer patients, chemo and radiotherapy can cause infertility by damaging spermatogenesis process. this process is based on self-renewal and differentiation of a rare population of the testicular cells called spermatogonial stem cells (sscs). scientists have tried to isolate, enrich and culture human spermatogonial stem cells, hoping to resolve infertility problems in cancer reco...

background and objectives: acetic acid bacteria (aab) are useful in industrial production of vinegar. the present study aims at isolation and identification of acetic acid bacteria with characterization, optimization, and evaluation of their acetic acid productivity. materials and methods: samples from various fruits were screened for presence of acetic acid bacteria on glucose, yeast extract, ...
