The flow control in twin air-intakes is necessary to improve the performance characteristics, since the flow traveling through curved and diffused paths becomes complex, especially after merging. The paper presents a comparison between two well-known techniques of flow control: active and passive. It presents an effective design of a vortex generator jet (VGJ) and a vane-type passive vortex gen...

introdouction: the purpose of the present study was to determine the possible relationship between gonial angle size and three mandibular morphometric parameters, namely, panoramic mandibular index (pmi), mandibular cortical width (mcw), and antegonial notch depth (ad), in digital panoramic radiographs. materials and methods: pmi, mcw, and ad were calculated in digital panoramic radiographs of ...

Background and aims: Bread is considered as one of the important sources of sodium in the Iraniandiet and salt is the main source of sodium, which is used to produce bread. The assessment of dietaryintake is a reliable method that shows nutritional problems in the community. Therefore, the purposeof this study was to evaluate the intake of salt, sodium, and potassium through b...

Abstract The most important design index of water intakes is critical submergence depth the intake. at which air core formed by vortex about to enter emergence a and entry into intake increase head loss decrease discharge coefficient. reservoir geometric asymmetry, presence unevenness in bottom angle approach flow are among factors that influence formation depth. In this research, physical mode...

cold roll-forming is a process in which the roll of sheet is formed by passing continuously through the set of rotary rollers without changing thickness in a cool way until it is formed to the desired profile. in this paper a parametric study on the section twist angle in roll-forming the non-symmetric channel is presented, using finite element simulation. at first finite element simulation res...

BACKGROUND Malnutrition is a major problem among children with Chronic Kidney Disease (CKD) and it is essential to be recognized as early as possible. Aim of our study was to assess the nutrition status of children with CKD. METHODS Nutrition status of 30 children (1-16 years) with CKD stages IIIV and on peritoneal dialysis was evaluated. Malnutrition risk was assessed by Pediatric Digital Sc...

for assessment and comparison of measuring density methods of festuca ovina, bromus tomentellus and prangos ferulacea, three plants communities are selected. in all of plant community, reference area was defined and samples 7000 (70*100) square meter was selected. whole the area, sampling was accumplished as systematic-random. in each area, 5 transect 100 meter are established. then in areas 70...
