Soil characteristics are the most powerful factors in desertification phenomenon. The purpose of this study was investigating soil characteristics as indices for evaluating desertification intensity. The most important indicators of the soil that affect desertification were selected in the present study. Soil samples were taken from Segzi desert vicinity located in the east of Isfahan city with...
in solvo-hydrothermal method, xrd pattern was indicated presence of intermediate of ammonium octatmolybdate and ammonium tetramolybdate, which were changed to stble phase of ?-moo3 annealing. sem images were indicated nanoparticle with semispheical morphology and tem image was demonstrated nanoparticles with a diameter size of 25nm. also in impregnate method. the xrd pattern was shown high crys...
The Imam Khomeini sugarcane agro-industry is one of ten sugarcane agro-industry plantations in Khuzestan province. As regard as the drains has been installed in this plantation many years ago so there is water and salt balance in this land that is one of the condition for implementation controlled drainage. This research was designed to investigate the possibility of using a controlled drainag...
Introduction: Considering the increasing population and the growing need for food and drinking water, it is essential to explore and understand the factors of crop production, especially water resources. Today, the removal of undiluted water from underground water sources has produced qualitative issues, in addition to a few shortcomings. These issues are more significant in arid and semi-arid ...
Two distinctly different ATPases have been reported to be endogenous to the mitotic apparatus: a Mg2+-ATPase resembling axonemal dynein, and a Ca2+-ATPase postulated to be bound in membranes. To examine the nature of the Mg2+-ATPase, we isolated membrane-free mitotic spindles from Stronglylocentrotus droebachiensis embryos by rapidly lysing these in a calcium-chelating, low-ionic-strength buffe...
Forty-eight water samples (30 groundwater and 18 surface samples) were collected from the study region. Physical chemical examinations performed on to determine values of various variables. Several graphs, sheets, statistical measures, including sodium solubility percentage (SSP), absorption ratio (SAR), Piper’s diagram, used plot concentration principal ions chloride mass balance (CMB). The co...
We investigate the use of direct-Fourier (DF) image reconstruction in computerized tomog-raphy and synthetic aperture radar (SAR). One of our aims is to determine why the convolution-backprojection (CBP) method is favored over DF methods in tomography, while DF methods are virtually always used in SAR. We show that the CBP algorithm is equivalent to DF reconstruction using a Jacobian-weighted 2...
Groundwater is an important source for a drink and irrigation in the Blinaja river basin. Understanding knowledge of water quality critical to management long-term productivity. Historically this study area there no data information regarding use needs. Therefore, was need assess based on analysed from eight sampling points. The purpose paper evaluate, relying analytical results, groundwater ba...
abstract: since sugar consumption is directly related to diabetes and other illnesses such as obesity, the issue that will most heavily dominate the health food market is blood sugar management and low glycemic foods. using calcium chloride and gums such as sodium alginate and low ester pectin as thikener and a high-potency sweetener aspartame we were able to reduce sugar content of sour cherry...
Assessing water quality is crucial for improving global resource management, particularly in arid regions. This study aims to assess and monitor the status of groundwater based on hydrochemical parameters by using artificial intelligence (AI) approaches. The irrigation index (IWQI) predicted support vector machine (SVM) k-nearest neighbors (KNN) classifiers Matlab’s classification learner toolb...
