The archaeozoological record of terminal Pleistocene to Middle Holocene sites in the Central Sudanese Nile and Upper Atbara regions is interpreted in terms of environmental change. On the basis of the species composition of the faunal assemblages, shifts in climate and Vegetation can be observed. Using the present-day position of the Vegetation zones, the extent of their north-south movements d...

abstract the aim of this paper is to investigate annual and seasonal precipitation trends of some selective meteorological stations of central region in iran using non-parametric methods. two non-parametric methods including mann-kendall and sen's estimator slope methods were used here to analyze the seasonal and annual trends of precipitation data. some 48 meteorological stations in centr...

Suppose that f = ∑ n≥1 an(f)q n is a cusp form of weight 2k (k ∈ N). We denote by L(f, s) the L-function of f . For Re(s) sufficiently large, the value of L(f, s) is given by L(f, s) = ∑ n≥1 an(f) ns , and one can show that L(f, s) has analytic continuation to the entire complex plane. The value of L(f, s) at s = k will be of particular interest to us, and we will refer to this value as the cen...

Formulas for computing the Cartesian components of the static (DC) fields of horizontal electric dipoles ( HEDs) and vertical electric dipoles ( VEDs) located in the central zone of a three-layer horizontally stratified medium are derived and presented in a summary form suitable for immediate computation. Formulas are given for the electric and magnetic field components in the upper and central...

In this paper, we integrate goal programming (GP), Taylor Series, Kuhn-Tucker conditions and Penalty Function approaches to solve linear fractional bi-level programming (LFBLP)problems. As we know, the Taylor Series is having the property of transforming fractional functions to a polynomial. In the present article by Taylor Series we obtain polynomial objective functions which are equivalent...

 Abstract Reports have shown that molars can be distalized successfully with virtually no orthodontic anchorage loss with an intraosseous anchorage, even with fully erupted second molars. The purpose of this study was evaluating the effects of mini-screws as skeletal anchorage for upper molar distalization. In this case series, three patients needing maxillary first molar distalization,...
