Corrugated web beams made of cold-formed steel components represent an economical solution for structures, offering high flexural capacity and deformation rigidity. For conventional corrugated beams, thick plates the flanges thin sinusoidal sheets web, elements can be joined by standard bolted end-plate connections. In case thin-walled only, additional are required to accommodate shape position...

Steel Plate Shear Wall (SPSW) is an emerging seismic load-resistant system that, compared to other systems, enjoys the advantages of stable ductile behavior, fewer detailing requirements, rapid constructability, and economy. American seismic provisions decree that a SPSW should be designed as a moment frame with a web infill plate. Specifically, in case of buildings taller than 160 ft, it decre...

web usage mining (wum) is the automatic discovering of hidden informationof user access pattern from the web log data. frequent pattern discovery is one ofthe main techniques in wum that can be used to implement recommender systems,forecast user`s navigational behaviour, and personalize web sites. many algorithmshave been suggested on obtaining frequent user navigation patterns. this paperprese...

introduction: in this study the effect of matricaria recutita extract on acute pain in the presence and absence of flumazenil (antagonist of benzodiazepine) and lesioned paragigantocellularis (pgi) nucleus was investigated. method: wistar male rats (250±20 g) were used. animals were grouped randomly into intact, sham and bilateral lesion of pgi nucleus. intact and lesioned animals, each divided...

background: considering that elisa method presently is the test of choice for diagnosis of fasciolo­sis, the present study was undertaken to evaluate the maximum validity of coated plates at dif­ferent temperatures and different times during one year of evaluation. methods: serum samples of patients infected with fasciolosis (n=10), hydatidosis (n=5), toxocaria­sis (n=5), and negative control s...

volar lunate dislocation is the fourth and last stage of perilunate dislocation. it is an uncommon injury of the wrist and its bilateral occurrence is so rare that only one case has been reported in the literature. we are presenting the second case of this kind of wrist injury, its treatment and outcome. keywords : lunate bone, perilunate, volar plate, bilateral, dislocation.

vast application of the antibiotic drugs in animals without due attention  to withdrawal times necessitates quality control of food stuff in terms of antibiotics' residues. antibiotic residues in food stuff cause bacterial resistance, allergic reactions, toxicity,  carcinogenic effects and change of natural micro flora of intestine in consumers. so, the aim of the present study is detectio...

objective: the present study was aimed to correlate the clinical tests with the laboratory measures under dual task conditions in parkinson's disease (pd). materials and methods: eleven people with idiopathic pd (modified hoehn and yahr scores 1-3) were selected by simple non-probability sampling. center of pressure (cop) data obtained by force platform was used to calculate mean total velocity...

conclusions the fixator-assisted lengthening plate technique helps to maintain the stability and alignment at both sides of an osteotomy during tibial elongation. it allows the early removal of the external fixator immediately after lengthening is completed. this technique can be applied in children with open physes and in patients with a narrow medullary canal who are unsuitable for limb lengt...

the present article is a review of a palaeobiogeographic analysis of jurassic ostracods from east africa, india and madagascar and includes also some general remarks on palaeobiogeography, biodiversity and ostracod ecology.the palaeobiogeographic study shows the high significance of this microfossil group for the reconstruction of palaeogeographic processes, particularly plate tectonic developm...
