The aim of the study was to assess soil technogenic radioactivity in vicinity Morzhovets Lighthouse and surrounding areas by measuring radio caesium (137Cs) specific activity. Location time study. Field work performed area around (the Island, Archangelsk region) summer 2022. Methods. Soil samples were collected at 26 sites from 0-5 cm layer, which 12 also 5-10 и 10-20 layers. Aboveground phytom...
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
Soil organic matter stability and transformation affected by agriculture is a global problem of great concern. This study aimed to reveal structural changes in humic molecules under conventional soil tillage Cambisols the Transbaikal area. Humic acids were isolated from humus horizons native arable variants Eutric Cambisol Cryic (gleyic, humic, loamic) forest steppe, Haplic (arenic, protocalcic...
Leaf diseases’ influence the relationship between the yield and yield components of winter wheat (Triticum aestivum L.). Field experiments were conducted during 2003–2006 on a light loamy gleyic cambisoil in the central part of Lithuania to determine how leaf disease severity level affects grain yield and yield components. The area under disease progress curves (AUDPC), grain yield and yield co...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
در محیط محاسبات فراگیر، تمام وسیله هایی که قصد برقراری ارتباط با یکدیگر را دارند با رویدادها سر و کار دارند. به همین دلیل، کشف سرویس ها و مدیریت رویدادها در این محیط از حساسیت و پیچیدگی محسوسی برخوردار است. با توجه به اهمیت موضوع، هدف این رساله ارائه ی شیوه ایست که با استفاده از پایگاه داده ی فعال و به کارگیری قوانین eca (event, condition, action)، پیچیدگی رویدادهای بین وسیله ها را کاهش داده ...
Vast areas of Western Siberia (about 40%) are occupied by saline soils. Solonetzic agricultural lands mainly used for growing perennial grasses - phytomeliorants. To increase the yield fodder crops on solonetz lands, specialists Siberian Research Institute Fodder Crops in 80s last century developed phytomeliorative crop rotations. The article considers effect grassing rotations with a mixture b...
تعیین پارامترهای سینتیکی و ضرایب استوکیومتری واکنش هیدروکراکینگ و بررسی سینتیکی واکنشهای گوگردزدائی و ازت زدائی در حضور هیدروژن که عنوان پروژه را تشکیل می دهد ابزاری لازم جهت مشابه سازی سیستم راکتوری هیدروکراکینگ برای طراحی صنعتی، کنترل راکتور و نهایتا دستیابی به دانش فنی (maximum isomerezation) isomax برشهای سنگین نفتی و تبدیل آنها به فرآورده های سبک و میان تقطیری (دیزل و کروسین) می باشد. درای...
