در مطالعه حاضر، تغییرات میانگین سطوح غذایی (mtl)، طبقات غذایی صید (trc) و میزان صید (lp) جوامع دریایی (49 ذخیره شیلاتی) استحصال شده در مناطق صیادی هرمزگان (شمال خلیج فارس و دریای عمان)، طی یک روند زمانی ده ساله از 1390- 1381 مورد بررسی قرار گرفت. میزان صید طی این دوره یک روند افزایشی (001/0p<، 88/0 (r= را نشان داد، حال آنکه میانگین سطوح غذایی صید کاهش معنی داری را از سال 1381 تا 1390 داشته است ...
UV-B radiation and EOD light (EOD) quality has both signaling and damaging effects based on the dosage and time of exposure. At highland areas UV-B decreases crop productivity and also light quality increase at high elevation area but EOD light quality effect was not researched based on altitude. Therefore, in the present study a field experiment was conducted to investigate the effects of UV-B...
Recent advances in neural radiance fields (NeRFs) achieve state-of-the-art novel view synthesis and facilitate dense estimation of scene properties. However, NeRFs often fail for outdoor, unbounded scenes that are captured under very sparse views with the content concentrated far away from camera, as is typical field robotics applications. In particular, NeRF-style algorithms perform poorly: 1)...
A sustainable chemical industry needs to quantify its emissions and resource consumption by life cycle assessment (LCA). However, LCA requires detailed mass energy balances, which are usually not available at early process development stages. Here, we introduce a framework (A PROcess-specific, PRedictive impact AssessmenT method for Emerging processes, APPROPRIATE) provide fully automated, pred...
