Genetic variations between indigenous fat-tailed sheep populations

Blood samples were collected from a total 816 sheep of both sexes in three Iranian fat-tailed breeds (Sangsari, Makoei, indigenous sheep on firoozkouh mountain) serum, plasma and erythrocyte were separated and were frozen at -20°C. Variation in their blood proteins, albumin, haemoglobin and transferrin were examined to characterize the breeds and to obtain genetic relationship among them. Only transferrin was polymorphic in all breeds investigated; while albumin was monomorphic for S allele and haemoglobin was fixed for the B allele in three breeds.Keywords: Sangsari, makoei, firoozkouhi, fat-tailed, albumin, transferrin, haemoglobinAfrican Journal of Biotechnology Vol. 9(36), pp. 5993-5996, 6 September, 201

Assessment of cadmium and lead in the water and trout fish (Salmo trutta) of Zayandehroud River, a case study of Zarinshahr rice farms, Isfahan

This study aimed to investigate the concentrations of two heavy metals, lead and cadmium, in the water of Zayandehroud River which is surrounded by Zarinshahr rice farms. Water was sampled from a depth of 30 cm during June, July and August 2015, i.e. during the process of planting, growing and after harvesting, in three stations. Water was collected from three points; 20m before the farms, beside the farms and 100m after the farms. Three water samples and one trout fish (Salmo trutta) sample were collected each month and the concentrations of lead and cadmium were measured in the kidney, liver and gills of trout fish. The results showed that the amounts of lead and cadmium in the water were less and more than standard levels for these metals, respectively. The average concentrations of cadmium in the water were 15.81, 11.25, 8.92 μg/L during June, July and August, respectively. It is evident that the amount of cadmium in water was significantly higher in June during the planting phase and use of fertilizers and pesticides was more than the other months (p≤0.01). There was a correlation in cadmium and lead concentrations between water and fish organs (kidney, liver and gill)

Bell's inequality with Dirac particles

We study Bell's inequality using the Bell states constructed from four component Dirac spinors. Spin operator is related to the Pauli-Lubanski pseudo vector which is relativistic invariant operator. By using Lorentz transformation, in both Bell states and spin operator, we obtain an observer independent Bell's inequality, so that it is maximally violated as long as it is violated maximally in the rest frame.Comment: 7 pages. arXiv admin note: text overlap with arXiv:quant-ph/0308156 by other author

Exponential inequalities for positive linear mappings

In this article, we present exponential-type inequalities for positive linear mappings and Hilbert space operators, by means of convexity and the Mond-Pe\v cari\'c method. The obtained results refine and generalize some known results. As an application, we present extensions for operator-like geometric and harmonic means
