the aim of this paper is eliminating cr(vi) by natural hap. hap is a inexpensive material which is used from bovine critical bone ash in order to remove heavy metal ions like cr(vi). some experiments in different ph are performed (ph=2,3,7). maximum adsorption was appeared at ph=2, dosage=0.3 gr, c0=10 mg/l. cr(vi) removal depends on ph value and initial amount of cr(vi) result of experiments w...
High voltage XLPE power cable is a very important part of power system. The degree of electric-tree aging in the cable can be estimated effectually by measuring partial discharge. An on-line partial discharge monitor system of XLPE power cable was developed based on the virtual instrument designing conception. This system has the advantage of wide analog bandwidth, excellent anti-interference a...
learning english is very popular all over the world nowadays and it is considered a high prestigious language among citizens of different societies. one of the most important materials for learning a new language are textbooks. the debate that whether learning a new language is natural and neutral or ideological and influential on people’s worldviews, has always been of great importance.
Bu çalışmada orta gerilimli yer altı kablolu elektrik dağıtım şebekelerinde oluşan arızıları tespit etmek amacıyla kablo arıza teşhis cihazı tasarlanmıştır. cihazla Darbe Yansıma Metodu kullanılarak 40 kV’a kadar darbe jeneratörü ile arızanın yerini noktasal olarak edilmesi amaçlanmıştır. Bunun için 0-8 kV, 0-16 kV ve 0-32 kV’luk, aralıklarında 2.000 Joule enerjiye sahip bir Arızalı fazın tespi...
Wireless power transfer (WPT) has been found to be a practical replacement for cable power transfer which provides a wide range of applications. This technology offers a remarkable solution for charging electric vehicles (EVs) due to more convenience and increased safety. Moreover dynamic (in-motion) wireless charging offers the possibility of reducing the energy storage requirement on the veh...
The energy demand in the World is increasing day by day due to rapidly increasing population and advancement in science and technology. But in present era there are too many obstacles which decrease the consumption of electricity for common peoples, high cost of fuel, high demand and low supply of fuel. Fuels like coal, petroleum, CNG, LPG, nuclear energy are depleting day by day and also degra...
BACKGROUND The purpose of this study was to investigate the demographic and clinical characteristics of electrical injuries, laboratory findings, complications, and mortality and morbidity rates of these injuries. METHODS Patients with electrical injuries admitted to the emergency department between January 2006-2010 were retrospectively analyzed. The cases were evaluated by age, gender, sour...
Power systems for South and Central America based on 100% renewable energy (RE) in the year 2030 were calculated for the first time using an hourly resolved energy model. The region was subdivided into 15 sub-regions. Four different scenarios were considered: three according to different high voltage direct current (HVDC) transmission grid development levels (region, country, area-wide) and one...
در بخش نظری این پایان نامه، سهم کوارک نوع پائین از کوارکهای نسل چهارم (b?)، در ممان دوقطبی الکتریکی کوارک top، تنها با در نظر گرفتن نمودارهای تک حلقه مطالعه شده است. با استفاده از قیود شناخته شده بر روی ممان دو قطبی الکتریکی کوارک top، حدی بر روی جرم کوارک b? گذاشته شده است. سپس با استفاده از نسبت جرم های کوارک های نسل چهارم که از سایر مطالعات بدست آمده، و همچنین قید به دست آمده بر روی mb? ناشی...
