Algorithm of constructing hybrid effective modules for elastic isotropic composites

The algorithm of constructing of new effective elastic characteristics of two-component composites based on the superposition of the models of Reiss and Voigt, Hashin and Strikman, as well as models of the geometric average for effective modules. These effective characteristics are inside forks Voigt and Reiss. Additionally, the calculations of the stress-strain state of composite structures with new effective characteristics give more accurate prediction than classical models do

Impact of socio-demographic structure of the deaf people communities in prevalence of hereditary hearing loss

Hearing loss caused by environmental or genetic factors concerns more than 10 % of the world population. It leads to disability and considerably reduces the life quality of deaf people. On average, 1 in 1,000 newborns are born deaf, and 50-60 % of cases are due to genetic causes. Nonsyndromic hereditary deafness is a monogenic disease with uniquely high genetic heterogeneity. The prevalence of some forms of genetic deafness varies in different populations and could be determined, as for many other genetic diseases, by the ethnic composition of a population, isolation, founder and «bottleneck» effects, the proportion of consanguineous marriages, and probable heterozygote advantage. It is assumed that high prevalence of hearing loss due to mutations in the GJB2 (Cx26) gene was also influenced by some social factors: a long-standing tradition of assortative marriages between deaf people, combined with growth of their social adaptation and genetic fitness. The start for these events was the breakdown of the deep social isolation of deaf people, which occurred about 300 years ago in Europe, and later in the US, when special schools for the deaf with learning sign language as a common tool for communication were established (linguistic homogamy). Computer simulations and comparative retrospective study showed that over the past 200 years these social processes can have doubled the frequency of deafness in the US caused by the GJB2 gene mutations. Information about the sociodemographic structure of deaf communities in the past is extremely limited by an almost complete lack of relevant archival data. Nevertheless, studies of sociodemographic and medical-genetic characteristics of deaf people’s contemporary communities are important for predicting the prevalence of inherited forms of deafness, as well as for understanding the impact of social factors on the evolutionary processes occurring in human populations

Genomic analyses inform on migration events during the peopling of Eurasia.

High-coverage whole-genome sequence studies have so far focused on a limited number of geographically restricted populations, or been targeted at specific diseases, such as cancer. Nevertheless, the availability of high-resolution genomic data has led to the development of new methodologies for inferring population history and refuelled the debate on the mutation rate in humans. Here we present the Estonian Biocentre Human Genome Diversity Panel (EGDP), a dataset of 483 high-coverage human genomes from 148 populations worldwide, including 379 new genomes from 125 populations, which we group into diversity and selection sets. We analyse this dataset to refine estimates of continent-wide patterns of heterozygosity, long- and short-distance gene flow, archaic admixture, and changes in effective population size through time as well as for signals of positive or balancing selection. We find a genetic signature in present-day Papuans that suggests that at least 2% of their genome originates from an early and largely extinct expansion of anatomically modern humans (AMHs) out of Africa. Together with evidence from the western Asian fossil record, and admixture between AMHs and Neanderthals predating the main Eurasian expansion, our results contribute to the mounting evidence for the presence of AMHs out of Africa earlier than 75,000 years ago.Support was provided by: Estonian Research Infrastructure Roadmap grant no 3.2.0304.11-0312; Australian Research Council Discovery grants (DP110102635 and DP140101405) (D.M.L., M.W. and E.W.); Danish National Research Foundation; the Lundbeck Foundation and KU2016 (E.W.); ERC Starting Investigator grant (FP7 - 261213) (T.K.); Estonian Research Council grant PUT766 (G.C. and M.K.); EU European Regional Development Fund through the Centre of Excellence in Genomics to Estonian Biocentre (R.V.; M.Me. and A.Me.), and Centre of Excellence for Genomics and Translational Medicine Project No. 2014-2020.4.01.15-0012 to EGC of UT (A.Me.) and EBC (M.Me.); Estonian Institutional Research grant IUT24-1 (L.S., M.J., A.K., B.Y., K.T., C.B.M., Le.S., H.Sa., S.L., D.M.B., E.M., R.V., G.H., M.K., G.C., T.K. and M.Me.) and IUT20-60 (A.Me.); French Ministry of Foreign and European Affairs and French ANR grant number ANR-14-CE31-0013-01 (F.-X.R.); Gates Cambridge Trust Funding (E.J.); ICG SB RAS (No. VI.58.1.1) (D.V.L.); Leverhulme Programme grant no.

Ultraviolet disinfection of activated carbon and its use for microbiological decontamination

As a water treatment technique, UV-light is known to be an effective disinfectant due to its strong germicidal ability.
