in this study, the ability of generalized additive model (gam) for mapping potential distribution of ferula ovina boiss, and the description of species response curves to environmental variables were examined in fereidonshar region with area of 1000 square kilometers located in west of isfahan province. the presence and absence data of the species were collected from 278 sites (including 138 pr...

Hereditary hemochromatosis is inherited in an autosomal recessive manner with partial biochemical expression in heterozygotes. A high percentage of saturation of serum transferrin is the hallmark of the disorder, and serum ferritin concentration gives an approximate estimation of the size of iron stores. Hepatic computed tomography, magnetic susceptometry, and nuclear magnetic resonance provide...

This paper presents the heat transfer coefficients measured during HC-290 (Propane) vaporisation inside a brazed plate heat exchanger: the effects of heat flux, saturation temperature (pressure) and outlet conditions are investigated. The heat transfer coefficients show weak sensitivity to saturation temperature (pressure) and great sensitivity to heat flux and outlet conditions. The saturated ...

Physico-chemical properties of three Fadama farm site soils located in Ado-Ekiti, IkereEkiti and Ifaki Ekiti, all in Ekiti State, Nigeria, were evaluated. The parameters evaluated for were pH, particle size distribution, free Fe2O3 and Al2O3, organic matter, base saturation percentage and total exchangeable bases in eleven zones and thirty-three soil samples. The pH values showed that the soils...

Epitaxial copper ferrite thin films were deposited on MgO substrates by the alternating target laser ablation deposition method. A series of films was studied to explore the impact of oxygen operating pressure, substrate temperature, and the ratio of laser shots incident on each target upon the magnetic, structural, and atomic structural properties. The highest saturation magnetization, 2800 G,...

The nucleotide divergence at synonymous third sites between two lineages will increase with time since the latest common ancestor, up to some saturation level. The "null-hypothesis divergence" is defined as the percentage of difference predicted at synonymous third sites, allowing for amino acid composition and codon bias, but assuming that codon bias is the same at all sites occupied by a give...

Percentage error (relative to the observed value) is often felt to be more meaningful than the absolute error in isolation. The mean absolute percentage error (MAPE) is widely used in forecasting as a basis of comparison, and regression models can be fitted which minimize this criterion. Unfortunately, no formula exists for the coefficients, and models for a given data set may not be unique. We...

In humans, clofibrate increases the degree of bile cholesterol saturation and predisposes patients to cholesterol gallstone formation. To determine if this activity extends to the related hypolipidemic agent fenofibrate, duodenal bile lipid composition was studied in 15 subjects before they participated in a double-blind study of that drug. Eight subjects were studied again on fenofibrate and s...

The relative contribution of genetic factors to biliary and serum lipid composition was studied in 17 monozygotic and 18 dizygotic middle aged male pairs of twins. Cholesterol precursors, squalene and Methylated sterols which reflect the activity of cholesterol synthesis were also measured. Pairwise intraclass correlations were determined for monozygotic and dizygotic twin pairs and heritabilit...
