The experiment was conducted at Department of Horticulture, College Dr. Balasaheb Sawant konkan Krishi Vidyapeeth Dapoli (MS) during 2020-21 to study the effect post-harvest treatments different chemical and plant growth regulators on physical characteristics sapota fruits cv. ‘Kalipatti’ storage ambient condition. Fast ripening Sapota stage results in their short shelf life which leads deterio...
to evaluate the effect of supplemental vitamin c (vc) levels on performance and immune response of broiler chicks, 300 day-old ross male broiler chicks were allocated to a completly randomized design of 5 treatments(500 and 1000 ppm in diet, 500 and 1000 ppm in drinking water and control). immunity was assessed as antibody production against infectious bronchitis virus (ibv) and newcastle disea...
امروزه آلودگی خاک با فراورده های نفتی به دلیل نشت مخازن سوخت و خطر انتقال از مهم ترین مشکلات زیست محیطی است، زیرا علاوه بر خطر انتقال به زنجیره غذایی امکان آلوده سازی منابع آب زیر زمینی نیز وجو دارد. لذا پاک سازی خاک های آلوده به فراورده های نفتی در محل بسیار با اهمیت می باشد. در این تحقیق پارامترهای موثر بر پاک سازی خاک آلوده به گازوئیل به روش خاک شویی با استفاده از شوینده سدیم دو دسیل سولفات ...
To optimize large-scale distribution networks, solving about 1000 middle scale (around 40 cities) TSPs (Traveling Salesman Problems) within an interactive length of time (max. 30 seconds) is required. Yet, expert-level (less than 3%) accuracy necessary. To realize the above requirements, a knowledge-embedded multi-stage GA method was developed. This method combines a high-speed GA with a knowle...
Tetranychus urticae Koch,1836 ( Acari: Tetranychidae ) یک آفت پلی فاژ در جهان است که دارای سازگاری و تولید مثل بالا می باشد. استفاده از سموم شیمیایی باعث ایجاد مقاومت و عدم کارایی برخی سموم گردیده، لذا استفاده از عصاره های گیاهی، از اهداف اصلی این تحقیق می باشد. در این مطالعه عصاره های هگزانی و الکلی Decne, 1865 Proboscidea fragrans ،Linnaeus,1753 Nerium ole...

Highly sensitive and reliable hydrogen detection is prerequisite for the large-scale implementation of green energy hydrogen. It remains a tough challenge to get highly selective H2 sensor low concentration gas with working temperature. In this work, high performance flexible using ultrathin SnO2 film decorated by Pd nanoparticles (NPs) on polyimide (PI) was developed based versatile atomic lay...
