Abstract:
This study was carried out on the research station of sheep and goat (Abo Gharib, west of Baghdad, Iraq) to investigate the effects of some environmental factors on some growth traits in Awassi lambs as well as estimating heritability of these traits. Records of Awassi lambs included 1318 birth weights (BW), 821 weaning weights (WW) and 821 pre-weaning daily gains (DG) as recorded over three years (2007–2009). Records belonged to 120 sires. Restricted Maximum Likelihood (REML) method in a mixed model (paternal half sib) was utilized to estimate the heritability (h²) for above mentioned traits. The general statistical model included fixed effects due to parity, sex, year and month of birth, type of birth and age at weaning as covariate. The Best Linear Unbiased Prediction (BLUP) values of sires for all studied traits were estimated. Results showed that the means of BW, WW and DG were 3.85, 26.64 and 0.181 kg respectively. Studied traits were significantly (P < 0.01) affected by all fixed effects except the effect of sire on WW and DG, which was significant (P< 0.05). Heritability estimates (h²) of BW, WW and DG were 0.23, 0.12 and 0.19 respectively. The lowest and highest BLUP values for the mentioned traits were -0.325, 0.255 kg, -1.142, 1.284 kg, and -0.103, 0.053 kg respectively.

Abstract:
The article outlines the data on longevity factors and mountain water in factorial research of phenomenon of longevity in mountainous and field areas of Bulgaria. It was established the dependence among various internal and external factors on a phenomenon of longevity – the residence area, health status, gender and heredity. Natural waters derived from various Bulgarian water springs as well as water with varying deuterium content and the human blood serum of cancer patients were investigated by IR, NES and DNES methods. As estimation factor was measured the values of the average energy of hydrogen bonds (ΔEH...O) among H2O molecules, as well as local maxima in the IR, and DNES-spectra of various samples of water and human blood serum at ΔEH...O = -0,1387 eV (the DNES-method) and λ = 8,95 μm (the IR-method). The increased content of deuterium in water leads to physiological, morphological and cytology alterations of the cell, and also renders negative influence on cellular metabolism, while deuterium depleted water with the reduced deuterium content until the deep removal of deuterium (60–100 ppm) has beneficial effects on human health. For a group of people in critical condition of life and patients with malignant tumors the greatest values of local maxima in DNES-spectra are shifted to lower energies relative to the control group.

Abstract:
In this paper the biological influence of deuterium on cells of various taxonomic groups of prokaryotic and eucaryotic microorganisms realizing methylotrophic, chemoheterotrophic, photo-organotrophic, and photosynthetic ways of assimilation of carbon substrates (methylotrophic bacteria Brevibacterium methylicum, chemoheterotrophic bacteria Bacillus subtilis, photo-organotrophic halobacteria Halobacterium halobium, and green algae Chlorella vulgaris) was investigated at the growth on media with heavy water (2H2O). For all investigated microorganisms are submitted data on growth and adaptation on growth media containing as sources of deuterated substrates 2H2O, [2H]methanol and hydrolysates of deutero-biomass of methylotrophic bacteria B. methylicum, obtained after the multistage adaptation to 2H2O. The qualitative and quantitative composition of intra- and endocellular amino acids, proteins, carbohydrates and fatty acids in conditions of adaptation to 2H2O is investigated. It is shown, that the effects observed at adaptation to 2H2O, possess a complex multifactorial character and connected to physiological, morphological and cytological alterations – the magnitude of the lag-period, time of cellular generation, output of biomass, a parity ratio of synthesized amino acids, proteins, carbohydrates and lipids, and also with an evolutionary level of the organization of the investigated object and the pathways of assimilation of carbon substrates.

Abstract:
Our new work considers the problems of paleogenetics, archeology and antropology connected with origins of Corded Ware culture and early migration of Y-DNA R1 carriers. This work considers the Second Corded Ware Center on the Far East and Yakutia and its connection with the Eastern European one. Authors examine the hypothesis that the two Corded Ware cultures have the common source.
