The study of groundwater quality is typically conducted using water indices such as the Groundwater Quality Index (GQI) or GroundWater (GWQI). are calculated field data and a scoring system that uses ratios constituents to prescribed standards weights based on each constituent’s relative importance. results obtained by this procedure suffer from inherent subjectivity, consequently may have some...
این مقاله به ارزیابی شاخص کیفیت آب زیرزمینی در آبخوان لنجانات پرداخته است. شاخص کیفی آب به عنوان یک اندیس منحصر به فرد برای تشریح شرایط کلی کیفیت آب با استفاده از متغیرهای چندگانه کیفی ارائه گردیده است. اطلاعات فیزیکی و شیمیائی 66 نمونه آب از این دشت مورد ارزیابی قرار گرفته است. نتایج از مقایسه ویژگیهای کیفی استاندارد سازمان بهداشت جهانی (who) و استاندارد تحقیقات صنعتی ایران (isiri) حاصل شده ان...
Abstract The objective of this work was to propose a new stopping criterion shorten the computing time PampaPlus genetic improvement software, while maximizing qualification index (GQI) progeny, controlling inbreeding, and avoiding unintended culling. Data from two beef-cattle herds integrating were used. Five mating scenarios built using different numbers sires (9 37) dams (142 568). analyzed ...
BACKGROUND The geometric organization of myocytes in the ventricular wall comprises the structural underpinnings of cardiac mechanical function. Cardiac myosin binding protein-C (MYBPC3) is a sarcomeric protein, for which phosphorylation modulates myofilament binding, sarcomere morphology, and myocyte alignment in the ventricular wall. To elucidate the mechanisms by which MYBPC3 phospho-regulat...
A diffusion deconvolution method is proposed to apply deconvolution to the diffusion orientation distribution function (dODF) and calculate the fiber orientation distribution function (fODF), which is defined as the orientation distribution of the fiber spin density. The dODF can be obtained from q-space imaging methods such as q-ball imaging (QBI), diffusion spectrum imaging (DSI), and general...
Fiber orientation is the key information in diffusion tractography. Several deconvolution methods have been proposed to obtain fiber orientations by estimating a fiber orientation distribution function (ODF). However, the L 2 regularization used in deconvolution often leads to false fibers that compromise the specificity of the results. To address this problem, we propose a method called diffus...
In response to the difficulties of flood plain quality assessment, red-edge spectral remote sensing data acquired from Jilin-01 satellite were used. The Grassland Quality Index (GQI) was formed by Normalized Difference Vegetation (NDVI) and Red Edge (NDRE) related determination grassland first principal component Chlorophyll obtained analysis. GQI applied evaluate in flooded plain, which is an ...
ABSTRACT Several traits must be simultaneously considered in selection of tobacco cultivars for meeting the requirements farmers, manufacturers and consumers. Breeders should have an understanding associations between economically-important order to devise best strategy response all them. Utilization indices has been shown one most efficient selecting correlated characters. In tobacco, no repor...
Groundwater resources are important part of the sweet water available to humans. The present study studies and evaluates the quality of water resources of karstic basin of Roein Esfarayen. For this purpose, sampling of water from water sources was carried out and groundwater quality of the area was evaluated in terms of drinking, agriculture and industry using Schoeller, Wilcox and Langelier di...
Introduction Several deconvolution methods have been proposed to increase the angular resolution of HARDI or QBI [1][2]. However, there is no deconvolution method directly applied to diffusion ODF without resorting to spherical decomposition. In this study, we developed a deconvolution method that could be directly applied to diffusion ODF, thus extending its applicability to other q-space meth...
