To minimize unwanted noise, the exhaust gas of high pressure and high temperature coming out of internal combustion engine passes through silencer. Various types of silencers like absorptive, reactive and resonating, perforated type are widely implemented in actual practice .perforated reactive mufflers have an effective damping capability. This paper deals with comparative structural analysis ...

OBJECTIVE To compare postoperative vaginal incision separation and healing in patients undergoing posterior repair with perforated porcine dermal grafts with those that received grafts without perforations. Secondarily, the tensile properties of the perforated and non-perforated grafts were measured and compared. MATERIALS AND METHODS This was a non-randomized retrospective cohort analysis of...

in this paper, the axisymmetric corrugated diaphragm using finite element method will be discussed, so that half of these diaphragms’ cross sections and later the applied pressure will be considered. following this, using the consequent equations and visual basic software, a computer program will be provided which receives the diaphragms’ particulars such as diameter, thickness, pressure and th...

Watercress is a leafy vegetable of the family Brassicaceae that grows in and around water, it has a short shelf life (approximately seven days) and it is consumed raw or steamed. The objective of this work was to study the effect of packaging film and different storage temperature on the postharvest quality of watercress minimally processed. Treatments were: packed with plain film (PD961EZ, 31m...

Anomalies of the vagina are of interest not only to the obstetrician and gynecologist, but also to the general practitioner. When so extensive as to interfere with menstruation, sexual activities, oi with accouchement the effect of such anomalies upon the physical and mental health of the individual may be of considerable significance. Among the many possible abnormalities of the vagina, transv...

The objective of this paper is to study the elastic seismic response simplified building models that include considerations vertical lateral force resisting system (walls) and horizontal (floor diaphragms) through parametric study. assumption rigid diaphragms often used in design buildings; however, research suggests diaphragm may influence fundamental period response. In paper, a model present...

One way to increase the heat transfer is to use perforated twisted tapes with different hole diameters, which largely improve heat transfer with an increase in the heat transfer area at the constant volume and more mixed flow. In the previous studies, the effect of nanofluids with perforated twisted tapes is less studied. In this work, the performance of water / iron oxide nanofluid in a double...

To quantify the relationship between both regional and overall diaphragm morphometry and body weight in the dog, diaphragm thickness was measured in five regions of the costal diaphragm and three regions of the crural diaphragm in 40 healthy dogs (8-40 kg). Surface area of the diaphragm, diaphragm weight, and body weight were also determined. Diaphragm surface area and weight varied linearly wi...
