In this article the values of the coefficients of variation of 30 indicators of the biochemical composition of the fruits of the blueberry in a three-year cycle of supervision are presented. Signs with resistance against the complex influence of meteorological factors based on the level of the variability of traits are designated. On the basis of the comparative analysis of the averaged variation coefficients calculated for a varietal row of Vaccinium corymbosum L. during a long-term cycle of observation it has been established that the parameters of accumulation of solids, fructose, total soluble sugars, flavonols, total bioflavonols, benzoic acid, nitrogen, potassium, calcium and magnesium in fruits can be characterized by the smallest degree of genotypic variability and, consequently, of intervarietal distinctions, whereas the content of free organic acids, anthocyanins proper and the values of a sugar-acid index in fruits are characterized by the highest degree of genotypic variability

Adapting legume crops to climate change using genomic approaches

Our agricultural system and hence food security is threatened by combination of events, such as increasing population, the impacts of climate change, and the need to a more sustainable development. Evolutionary adaptation may help some species to overcome environmental changes through new selection pressures driven by climate change. However, success of evolutionary adaptation is dependent on various factors, one of which is the extent of genetic variation available within species. Genomic approaches provide an exceptional opportunity to identify genetic variation that can be employed in crop improvement programs. In this review, we illustrate some of the routinely used genomics‐based methods as well as recent breakthroughs, which facilitate assessment of genetic variation and discovery of adaptive genes in legumes. Although additional information is needed, the current utility of selection tools indicate a robust ability to utilize existing variation among legumes to address the challenges of climate uncertainty

Neogeodynamics phenomena investigation and computerized mapping in Belarus / A. Karabanov, R. Garetsky, R. Aizberg, T. Aronova, D. Kurlovich

The solution of the several problems of neogeodynamics phenomena investigation and mapping was one of the main tasks of the IGCP project No 346 "Neogeodynamics of Baltic Sea Depression and adjacent areas". Investigations performed for the project resulted in a series of international geodynamic maps showing vertical movements at the neotectonic stage, bottom part of Quaternary deposits, recent vertical movements, tectonic stress, epicenters of earthquakes, Moho discontinuity, neotectonic zoning and so on (Aizberg et.al., 2001; Garetsky et. al., 2003). Hence, the water surfaces of the Baltic Sea and the east part of the North Sea, the southern part of Scandinavia, the German-Polish Depression, the Central European block mountains and depressions, western part of the Russian Plain and, partly the Carpathians, were mapped. Despite of, that was done in traditional manner without any digitization, the set of maps showing structure and its dynamics from the Quaternary capping down to the Moho surface fulfils requirements of the modern Information Technology, thus it may and can be computerized in follows of the GIS rules. That will enable authors to supplement project with the newest data, and restructure its visual appearance, in the attached presentation, authors review some problems of geodynamic researches in Belarus. Keywords: Neogeodynamics, structural pattern, stress field, geological mapping, seismicit

Skin microbiota in patients with psoriasis vulgaris and pustular psoriasis

In the dermatological community there is no consensus regarding the role of infectious factors in the origin, course, exacerbation of psoriasis. the authors conducted a study on frequency of detection, quantitative and qualitative composition of the microbiota of the skin, mucous membranes of the throat and nose of patients with various forms of psoriasis, the relationship with the clinical picture. The goal of the study was to examine of the composition of the microbiota of the skin, the mucous membranes of the throat and nose of patients with various forms of psoriasis compared with healthy individuals. Materials and methods: inducted bacteriological examination of the surface of psoriatic elements, the contents of the pustules, the mucous membranes of the throat and nose in 49 patients, of them with generalized pustular psoriasis, palmoplantar pustular psoriasis, common exudative psoriasis, and vulgar psoriasis, mainly affecting the palms and soles. Was to study the intensity of the sensation of itching in patients on a 10 - points scale. Results: bacteriological examination of pathological lesions on the skin in patients with various forms of psoriasis highlighted various microorganisms in the diagnostically relevant concentrations with a predominance of gold and epidermal staphylococci. Shows the functional, statistically significant relations hip between the degree of intensity of itching and frequency of detection of Staphylococcus aureus. Conclusion: detection of diagnostically significant quantities of conditionally pathogenic microorganisms with a predominance of gold and epidermal staphylococci shows the possible role of infection in the development of immune inflammation in psoriasis. this regularity of the intensity of itching and detection of Staphylococcus aureus on the surface of the skin of patients with psoriasis may be an important factor in the current understanding of the significance of the role of infection in the development and course of psoriasis

Towards 14C-free liquid scintillator

A series of measurements has been started where the 14C concentration is determined from several liquid scintillator samples. A dedicated setup has been designed and constructed with the aim of measuring concentrations smaller than 10−18. Measurements take place in two underground laboratories: in the Baksan Neutrino Observatory, Russia, and in the new Callio Lab in the Pyhäsalmi mine, Finland. Low-energy neutrino detection with a liquid scintillator requires that the intrinsic 14C concentration in the liquid is extremely low. In the Borexino CTF detector the concentration of 2 × 10−18 has been achieved being the lowest value ever measured. In principle, the older the oil or gas source that the liquid scintillator is derived from and the deeper it situates, the smaller the 14C concentration is supposed to be. This, however, is not generally the case and the concentration is probably due to the U and Th content of the local environment.peerReviewe
