iran is ranked fourth for saline-sodic soils in asia following china, india and pakistan. therefore, if coupled with waterlogging, drainage would be an inevitable and indispensable activity agriculture in most irrigated parts of iran. drain installation depth is one of the main economic as well as environmental challenges in design and construction of drainage systems. deep pipe drain installat...
seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
the present study aimed at investigating how different news agencies using the concept of legitimation/delegitimation represent the same event differently. to this end, van leeuwens (2008) legitimatory/delegitimatory framework was applied to the data gleaned from the iranian state-run news agency fars news, british state-run news agency bbc, and also american state-run news agency voa. the resu...
This paper focuses on the noise behavior of nMOSFETs with high-k gate dielectrics (SiON/HfO2) with an equivalent oxide thickness of 0.92 nm and using metal (TiN/TaN) as gate material. From the linear dependence of the normalized drain noise on the gate voltage overdrive we conclude that the 1/f noise is dictated by mobility fluctuations. This behavior is mainly ascribed to the reduced mobility ...
Elite migration and brain drain trend in Iran have undergone a dramatic ascent in the past few decades while we are seriously in need of educated manpower to help accomplish the 20-year national vision. So to consider brain drain is necessary and must be accounted by policymakers in all levels. In the upcoming paper, we study the brain drain as a social problem and elaborate a five-dimensional ...
sive, be easy to apply and remove, ensure the security of the drain and maximize patient comfort. These goals are achievable, but often drain security is prioritized at the expense of patient comfort and practicality. We have found an effective method for dressing sutured drains with the use of a single “All-In-One” dressing or a 20 × 10-cm adhesive-absorbent pad (Primipore; Smith & Nephew, St....
The expatriation of the elites has undoubtedly been one of the most crucial national issues of the past two decades. From the early 1960s onward, brain drain has served as a problem, which researchers have studied form different perspectives using various approaches, so much so that giant global organizations such as the World Bank and the UNESCO conducted studies and attempted to offset its ef...
BACKGROUND Hematoma of the auricle which is a collection of blood beneath the perichondrial layer of the pinna usually poses a challenge to the otolaryngologist due to its high rate of recurrence after treatment and lack of appropriate material for use as stitch dressing especially, in the developing world. This is a Pilot study in which corrugated rubber drain was used as a stitch dressing aft...
