For the polynomial planar vector fields with a hyperbolic or nilpotent critical point at the origin, the monodromy problem has been solved, but for the strongly degenerate critical points this problem is still open. When the critical point is monodromic, the stability problem or the center- focus problem is an open problem too. In this paper we will consider the polynomial planar vector fields ...
The question of the origin of Islamic mysticism has been one of the major concerns of many researchers in the field of mysticism in the recent decades. Some have maintained that Islamic mysticism is an imported product: a combination of Eastern spiritual traditions or a mixture of Manichaeism and Alexandrian philosophy. However, in order to find out the real origin of Islamic mysticism, the bes...
The aim of this study was to evaluate the differences between cold carcass weights (CCW) for the Catalan Pyrenean horse (Cavall pirinenc català) breed according to different variables: area of origin, farm, gender and age. Linear regression models were applied using a generalized linear model (GLM) procedure for CCW of 397 animals (217 males and 180 females) slaughtered in a commercial abattoir...
background emergence of a novel swine-origin influenza a (h1n1) pandemic since 2009 attracted the attention of scientists to characterize epidemiological features and clinical manifestations of this disease in comparison to seasonal flu in different parts of the world. objectives the goal of this investigation was to compare these features in confirmed cases of swine-origin influenza a (h1n1) a...
در تحقیق حاضر به منظور اعتبارسنجی دادههای ماهوارهای در آبهای جنوب ایران، مقایسهای بین جریانهای سطحی ناشی از باد حاصل از دادههای میدانی و دادههای ماهوارهای[1]noaa در ناحیه بوشهر در سال 2008 بعمل آمده است. از دادههای میدانی جریانهای جزر و مدی فیلتر شده و سهم مربوط به جریانهای سطحی ناشی از باد مشخص گردیده است، سپس جریانهای باقیمانده را با جریانهای سطحی ناشی از باد حاصل از دادههای میدانی و...
The study investigated the stomach content of Sillago sihama in Hormuzgan Province waters located in the northern Persian Gulf from October 2009 to March 2010. The stomach analysis was carried out using frequency of occurrence and numeric methods. Diatoms, blue- green algae and dinoflagellates constituted main food of plant origin. Diatoms were found to be the most preferable food of plant ori...
Negative data handling has gained a remarkable importance in the literature of Data Envelopment Analysis (DEA) to address many real life problems. Various erstwhile applications, in this arena, referred relocation of the origin to a superior (RDM) or to an inferior (Translated Input Oriented BCC) neighboring point. In this paper, the conditions for Rotation Invariance of various Data Envelop...
