Clay soil is a that causes lot of problems, has low permeability and difficult to handle in the field. The grains are very fine composed minerals can be affected by water. If water content high this expands its strength decreases significantly damage structure above it. To overcome problem, researchers tried use brick waste as mixing material, because material commonly found composition bricks ...
بررسی تنوع ژنتیکی ژنوتیپهای بومی پیاز ایرانی در مقایسه با انواع خارجی چکیده: برنامه های اصلاحی گیاهان بر اساس تنوع و انتخاب صفات برتر کمی و کیفی صورت می گیرد. لذا، ارزیابی تنوع ژنتیکی، اولین مرحله در برنامه های اصلاحی است. در این راستا، استفاده از روش های جدید مطالعهی تنوع ژنتیکی ضروری به نظر می رسد. در این بررسی تعیین تنوع ژنتیکی سیزده ژنوتیپ پیاز ایرانی در مقایسه با دو ژنوتیپ خارجی با است...
Due to physiography and weak structure, the pasture soils in Boroojen are potentially degradable. Converting pastures to agricultural land accelerates the degradation processes. A study was conducted in 1999 to show the effects of almost 20 years of farming on originally pasture land on soil physical properties, fertility, and tilth index of pastures in Boroojen region in Chahar Mahal and Bakht...

this thesis aims to adduce an unmitigated and comprehensive explication concerning the relationship of three significant elements of fiction: setting, chracter and theme. my research is basically placed on two outstanding novels of the 19th century: emily brontes wuthering heights and thomas hardys return of the native. my endeavour lies in studying the correlation among the three above-mention...
If clustering of the arrival directions of ultra high energy cosmic rays is discovered, this would provide important information about their origin, composition, and the galactic and extragalactic magnetic fields. We present here the analysis of the autocorrelation function of the data from the Pierre Auger Observatory as a function of the angular scale and the energy threshold. We compare our ...
the neogene intrusion masses in the noudeh-enghelab area located to the north of sabzevar ophiolite have cut the late cretaceous ophiolitic rocks, sedimentary- volcanic and eocene volcanic rocks and have been covered by pliocene and quaternary deposits. the margin is of lava with basalt, phyric andesite-basalt and andesite and the central parts (dome shaped) composed of phyric andesite-trachyan...
sericulture has played a very important role in the socio-economic empowerment of rural and semi-urban population. the eco-friendly nature of the industry, in addition to its employment generation potential, low investments and frequent returns, has rendered the industry as one of the most suitable land based economic activity, particularly in the context of global movement against environmenta...
Concrete is a quasi-brittle material and shows different behavior in compression tension. It elastic at initial stage damage-plasticity beyond limit. Therefore, development of model concrete complex phenomenon. In this study, damage plasticity theory has been described under experiment on cylinder considering uni-axial loading interpreted with analytical data calculated using CEB-FIP code equat...
