The spatial and temporal organization of ecological processes and features and the scales at which they occur are central topics to landscape ecology and metapopulation dynamics, and increasingly regarded as a cornerstone paradigm for understanding ecological processes. Hence, there is need for computational approaches which allow the identification of the proper spatial or temporal scales of e...
Allometric scaling is one of the most pervasive laws in biology. Its origin, however, is still a matter of dispute. Recent studies have established that maximum metabolic rate scales with an exponent larger than that found for basal metabolism. This unpredicted result sets a challenge that can decide which of the concurrent hypotheses is the correct theory. Here we show that both scaling laws c...
Background and Objective: The goal of this study was to describe the mediating role of self-concept in perfectionism and mental health.Materials and Methods: The sample group in this study included 400 high school students (200 boys and 200 girls) from Shiraz with the mean age of 16.37±0.93 for the girls and 16.12±0.63 for the boys. Data were gathered through the application of three scales: Ma...
In this paper, using vortex blob method (VBM), turbulent flow in a channel is studied and physical concepts of turbulence are obtained and discussed. At first, time-averaged velocities, and , and then their fluctuations are calculated. To clarify turbulence structures, velocity fluctuations and are plotted. It is observed that turbulence structures occupy different positions and move with con...
Introduction & Objective: Cardiovascular diseases and inadequacy of dialysis are the leading causes of mortality and morbidity in the dialyzing patients. Improvement of the dialysis efficacy has important role in improving the patient’s prognosis. Aim of the current study was to determine the adequacy of dialysis in patients under hemodialysis in dialysis department of Ekbatan Hospital of Hamad...
