Electrical energy is currently one of the main needs needed by humans to carry out daily activities. The process generating electrical carried through transformation various sources, either using conventional sources or renewable energy. One Renewable being developed wind power and solar power. However, in application these two there are still deficiency, namely value conversion efficiency smal...
introduction: citrus are one of the important orchard fruit production that after banana is second in production at the world level and every year, chemical fertilizers having most important role in increasing crops productions, but in long application of fertilizers cause soil destructions and polluting underground water. also soils of dry regions are very poor in organic matter level. nowaday...
این تحقیق برگرفته از نتایج طرحی است که با هدف بررسی اثر کاشت مستقیم ارقام گندم در بقایای ذرت، بر عملکرد و بهرهوری آب طی دو سال زراعی 96-95 و 97-96 انجام شده است. برای این منظور، آزمایشی به صورت کرتهای نواری خرد شده در قالب بلوکهای کامل تصادفی با سه تکرار در اراضی مرکز تحقیقات کشاورزی صفیآباد دزفول اجرا شد. کرت اصلی شامل روشهای بیخاکورزی (NT)، کمخاکورزی (MT) و خاکورزی مرسوم (CT) و کرت ...
Optimizations on 200 kV electrostatic accelerator have been done in order to increasing ion current on target, improving vacuum condition and reduction in x-rays emission, increasing stability of high voltage power supply and reaching much greater achievable voltage value. The accelerator tube has most important effect on beam tracing in the electrostatic accelerators. So precautions most be co...
Personality researchers have recently advocated the use of very short personality inventories in order to minimize administration time. However, few such inventories are currently available. Here I introduce an automated method that can be used to abbreviate virtually any personality inventory with minimal effort. After validating the method against existing measures in Studies 1 and 2, a new 1...
In the title compound, [Ca(NO(3))(C(34)H(32)N(10))]NO(3)·3CH(4)O, the Ca(II) ion is coordinated by six N atoms of the EDTB ligand {EDTB is N,N,N',N'-tetra-kis[(2-benzimidazol-yl)meth-yl]-1,2-ethanediamine} and two O atoms from the nitrate ligand, to form a distorted dodeca-hedral geometry. The crystal packing is stabilized by inter-molecular N-H⋯O, N-H⋯N and O-H⋯O hydrogen bonds, which link the...
Quantitative descriptions of a physical system’s behaviour form the backbone of the scientific method used in the natural sciences. They allow the principled determination of experimental parameters, a clear and unambiguous representation of experiments, and independent replication and verification of experimental results. In mobile robotics to date, quantitative descriptions of robot-environme...
OBJECTIVES This paper describes the development of a short version of the Malaysian Oral Health Impact Profile. METHODS The 45-item OHIP(M) was shortened using a method known as the 'item frequency method'. Here, the two most frequently reported items from each of the seven OHIP(M) subscales were chosen to form the short version, designated as the S-OHIP(M). Field testing was conducted to ass...
