cage roll forming is one of the new methods of cold roll forming process which is widely used for producing erw pipes. in addition to less production cost and time, using cage roll forming provides smooth deformation on the strip. few studies can be found about cage roll forming because of its complexity, and the available knowledge is more experience-based and not science-based. in this paper,...

BACKGROUND Skin flora varies from one site of the body to another. Individual's health, age and gender determine the type and the density of skin flora. METHODS A 1  cm² of the skin on the sternum was rubbed with sterile cotton swab socked in 0.9% normal saline and plated on blood agar. This was cultured at 35 °C. The bacteria were identified by culturing on MacConkey agar, coagulase test, ca...

Intraperitoneal injection of complete Freund's adjuvant which caused an extensive cellular response in the reticuloendothelial system greatly increased the severity of infection which resulted from footpad inoculation of ectromelia virus in mice. The mortality was greatest during the proliferative phase of the cellular response, indicated by the colony-forming cell response. Exposure of colony-...

we investigated the association between serum 25(oh) d levels and depressive symptoms in patients with major depressive disorder (mdd).eighty-five adults, 44 drug free patients with mdd and 41 apparently healthy controls, participated in the study. the hamilton depression rating scale was used to assess severity of major depression. mental health of the controls was assessed according to dsm-iv...

Single point incremental sheet metal forming is a sheet metal forming process that forms products without the complex dies and tools with low cost. In this study, the incremental sheet metal forming process has been experimentally investigated on the explosively-welded Al/Cu bimetal sheets. Also, the effects of process parameters, such as arrangement of layer`s bimetal, tool diameter and tool p...

In recent years, in order to reducing die design and manufacturing costs, Multi point forming technique has gained an increasing interest because of its high flexibility. In this process, the conventional fixed shape solid die sets are replaced with a pair of opposite matrices of controllable elements. In this paper, the fundamental principles of multi-point forming was described and the possib...

Background: Psoriasis vulgaris is a common chronic and inflammatory disease of skin that its etiology is not completely known. However, it seems that genetic and environmental factors play a role in this disease. In vitro studies show that prolactin as a neurohormone has an etiologic effect on psoriasis. This study aimed to compare serum prolactin levels in psoriatic patients with control group...

This study examined differences among transcription intelligibility scores and listener confidence ratings for three different types of speech stimuli--single words, unrelated sentences, and sentences forming a narrative--all produced by speakers with dysarthria. Twelve speakers with dysarthria of varying severity secondary to cerebral palsy and 144 listeners participated in this study. Results...
