In order to investigate the effects of range management plans on species diversity, richness and evenness in Semirum rangelands, 52 sites (28 with treated plan and 24 without treated plan) were selected. The non-parametric indices for species richness (Margalof, Menhinick, Jacknife and counting method) and species diversity (Simpson, Camargo, Smith and Wilson and modified Nee) were compared in ...
This paper we investigate the existence and uniqueness of solutions to fuzzydierential equations driven by Liu's process. For this, it is necessary to provideand prove a new existence and uniqueness theorem for fuzzy dierential equationsunder weak Lipschitz condition. Then the results allows us to considerand analyze solutions to a wide range of nonlinear fuzzy dierential equationsdriven by Liu...
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...
Atmospheric synoptic weather patterns have a significant impact on the concentration, dispersion, and transportation of air pollution in various regions times around world. To assess atmospheric long-range mass transportation, we used classification techniques from BP training model HYSPLIT model. Our research uncovered four conditions linked to PM10 concentration categories ranging normal extr...
introduction: educational justice is a process by which all those involved in education are pondering and seeking to establish it in their regulatory environments. this study aimed to investigate effective factors in an ideal educational justice and the current condition of educational justice from the students’ viewpoint and ultimately increase the awareness and understanding of authorities an...
Climate change is a global phenomenon, yet impacts on resource availability to predators may be spatially and temporally diverse asynchronous. As capital breeders, whales are dependent dense, predictable prey resources during foraging seasons. An Unusual Mortality Event (UME) of Eastern North Pacific (ENP) gray ( Eschrichtius robustus ) was declared in 2019 due dramatic rise stranded animals, m...
