Genetic and environmental (co)variance components for productivity traits in Moghani sheep were estimated using data from 1344 ewes. The data were collected in the Jafarabad breeding station, north-east of Iran, during a 13-year period (1995-2008). The studied traits were litter size at birth (LSB), litter size at weaning (LSW), litter mean weight per lamb born (LMWLB), litter mean weight per lamb weaned (LMWLW), total litter weight at birth (TLWB) and total litter weight at weaning (TLWW). A model including direct additive genetic effects as well as permanent environmental effects related to repeated records of ewe was the most appropriate model for all the studied traits. Genetic parameters were estimated applying restricted maximum likelihood (REML) procedure. Direct heritability estimate for LSB, LSW, LMWLB, LMWLW, TLWB and TLWW were 0.11, 0.02, 0.15, 0.07, 0.07 and 0.06, respectively. Corresponding values for repeatability estimates were 0.16, 0.19, 0.18, 0.11, 0.13 and 0.09. Genetic correlations between the studied traits ranged from -0.99 for LSB-LMWLB and LSW-LMWLB to 0.99 for LSB-TLWB. Phenotypic and environmental correlation estimates were generally lower than those of genetic ones. Estimates of permanent environmental correlation among traits were positive and medium to high. Although low direct heritabilities were estimated for the reproductive traits, as these traits are of interest then they should be included in a breeding program. © 2010.

Flood is a natural demolishing phenomenon, forecast of which is of high importance. Estimation of rainfall-runoff and flood is a difficult task due to influence of different factors. So far, different methods have been proposed to analyze such phenomena. This study was conducted in the basin of Sheikh Bahaei Dam in Isfahan Province to prioritize areas influencing the flood peak discharge or in other words, to specify areas with highest flood potential. HEC-HMS hydrological model was used to simulate the flow in the hydrological units of the area. The results showed that areas near the output point of the basin play the highest role in flood development and should be placed in the first priority of watershed management. The results can remarkably contribute to the monitoring system of the area.

There are a large number of chemicals, which are released into the Persian Gulf, capable of interfering with the synthesis and action of natural thyroid and testosterone hormones. These are considered as endocrine disruptors. In the present study, sea bream was exposed to four different concentrations (10, 20, 40, 80 μg l-1) of the widely used mercury chloride in a laboratory condition, and effects on the concentrations of serum testosterone and thyroid (T3 and T4) were assayed. Mercury chloride exhibited significant effects on both T3 and T4 (P < 0.5) concentration of serum. No significant changes occurred in the concentration of serum testosterone (P > 0.5); however, exposure to higher mercury chloride concentration showed suppressive effects on serum testosterone. Results of the present experiment indicated that mercury chloride induced alteration in the structure of the gonad and thyroid and can be considered as an endocrine disruptor substance in yellowfin sea bream. © 2012 Springer-Verlag London Limited.

Much attention has been paid to heterocyclic N-containing ligands due to their applicability as bridging ligands in the synthesis of redox active dinuclear metal complexes. With this aim, we report the synthesis and full characterization of a novel phthalazine-triazole ligand (1,4-bis(1-methyl-1H-1, 2,3-triazol-4-yl)phthalazine). Moreover, we show that the phthalazine nitrogen atoms of this N-heterocyclic ligand are more reactive towards alkylating agents than the triazole groups. New ruthenium(ii) complexes containing this ligand have been obtained and characterized both structurally and electrochemically. The geometry imposed by the ligand allows the placement of two ruthenium centers in very close proximity so that efficient through-space interactions take place, a concept of crucial importance for electron transfer processes. © 2014 The Partner Organisations.

The toxicity of vapours of the essential oil of Ferula gummosa, Elettaria cardamomum and Salvia officinalis on the adults and larvae of some stored product pests was investigated. The bioassays were carried out in 70 mL vials containing 10 individuals of each insect. The LC 50 values of fumigant bioassay after 24 h were calculated. Results indicated that the effect of the essential oil of F.gummosa was stronger than E. cardamomum, S. officinalis on stored pests. Also fumigant toxicity of S. officinalis on Sitophilus oryzae was similar to that of Sitophilus granarius adults. On the other hand, R. officinalis had a good effect on adults of Tribolium castaneum and larvae of Ephestia kuehniella. According to our results and good effect of these compounds, they will be a safe replace for chemical compounds in the future. © 2012 Taylor and Francis Group, LLC.
