Background Scorpion stings are the most important health problems in tropical and subtropical countries. The aim of this study was to assess spatial distribution of scorpions and scorpionism in Ardabil province, Iran. Materials and Methods This descriptive–analytic study wascarried out in all 10 counties of Ardabil province, Northwestern Iran.The clinical and demographic data of scorpion sting ...
The first and most important issue in forest drought management is knowledge of the location and severity of forest decline. In this regard, we used geostatistics and artificial neural network methods to map the dieback intensity of oak forests in the Ilam province, Iran. We used a systematic random sampling with a 250 × 200 m grid to establish 100 plots, each covering 1200 m2. The percentage ...
Evaluation and Mapping Spatial Distribution of Copper Pollution in Soil and Water of Vineyard Garden
Background and objectives: The use of copper based fungicides is a crucial part of agricultural operations in vineyards, increasing productivity and crops. However, the long term application of fungicide could increase the copper concentration in the vineyard soils. Methods: In this study, soil and water chemical parameters including copper contamination, pH and EC as well as soil organic ...
The flow field, velocity and pressure coefficient distribution of some 2-D ideal flows are presented. Conformal mapping is used to simulate two-dimensional ideal flow for a variety of complex internal and external configurations, based on the numerical integration of Schwarz-Christoffel transformation. The advantages of this method are simplicity and high accuracy. The method presented in this ...
The interrelationships among spatial distribution in the red, green, and blue channels of texture images of differently woven textile fabrics are investigated. A computational model for color mapping is developed based on the channel proportionality found in the investigation. The computational model developed has two modes: gray-to-color mapping (GCM) and color-to-color mapping (CCM) that deal...
