    The article gives the results of studies of the effect of soil and fertilizer treatment on the productivity of winter wheat in the Ganja-Gazakh zone of Azerbaijan. The positive effect of fertilizers on plants of winter wheat is manifested only in well-cultivated soils with a reaction of the environment close to neutral. At the same time it is proved that between the intensity of the application of mineral fertilizers and the productivity of grain crops around the world, a close direct dependence is established. Consequently, the highest yield of grain here was obtained in the variant of dung 10t / ha + N90P90K60  57.1 c / ha, an increase of 24.3 c / ha or 74.1%, where the yield increase by 40- 50% is due to the application of fertilizer

    430 mkn.ha of land has been damaged by erosion processes in different countries around the world. Surface, cleavage and irrigation erosion is also widespread throughout the country. 43.29% of the total area is subjected to varying degrees of erosion. In some regions, especially the Nakhchivan AR, erosion processes cover 70% of the area. 66.6 of the total area of the southern slope of the Greater Caucasus has been eroded. In some areas of the country, the percentage of eroded farms is high. This figure is 51% in Lachin-Kalbajar zone, 57.9% in Guba-Khajmaz zone and 72.4% in Sheki-Zagatala. The newly formed splinters break down the farmland into small parts and make them useless. The following erosion intensity scale is presented. 1) net wash-up to 0.5 t / ha, 2) poor wash-up to 0.5 t / ha, 3) moderate washing 1-5 t / ha, 4) severe washing -5-10 t / ha, 5) very severe washing -10 t / ha. Different geographical areas of the country have also been identified the possible distances between stripes on different slopes. Soil preparation should be carried out with a strip of 1–2 m in every 3–5 m in areas of 10–200 incidence, moderate to severe, and 1.5–3 m wide in each of the 2–3 m in severely washed areas of 20–300 m. trench to be dug. In large areas with more than 15-200 thick, thick soils and where the tractor can operate, deforestation should be carried out on terraces. On the slopes where heavily washed and often rigid rocks are exposed, soil preparation can be used to make yards and ditches

    The results of the study revealed that the mismatch intensity rain rate of water absorption into the soil formation of a surface relief and soil erosion, uneven and zakiraliyev soaking imperfection open irrigation system at a superficial irrigation, the need for different irrigation methods in the growing and not growing periods, low coefficient land utilization, high cost of irrigation and other features are, to a certain extent in conflict with the requirements of watering cultivated with techniques for / of crops in an area at the deep groundwater

    The main purpose of this study was to determine the protective factors that can aid people in their recovery or help maintain their well-being in the face of collective adversity, in this case, the COVID-19 pandemic, and to examine how these factors can be further strengthened. The study included 89 participants from 14 different cities in Turkey, ranging in age from 18 to 70, 46 of them men and 43 women. In light of the findings of the study, it can be said that psychosocial support and re-adaptation programmes are needed to ease the social-emotional burden of living through a pandemic on individuals (especially those who survived the virus) even after the COVID-19 pandemic ends

    Electron-phonon renormalization of the absorption edge of the cuprous halides

    Compared to most tetrahedral semiconductors, the temperature dependence of the absorption edges of the cuprous halides (CuCl, CuBr, CuI) is very small. CuCl and CuBr show a small increase of the gap E0E_0 with increasing temperature, with a change in the slope of E0E_0 vs. TT at around 150 K: above this temperature, the variation of E0E_0 with TT becomes even smaller. This unusual behavior has been clarified for CuCl by measurements of the low temperature gap vs. the isotopic masses of both constituents, yielding an anomalous negative shift with increasing copper mass. Here we report the isotope effects of Cu and Br on the gap of CuBr, and that of Cu on the gap of CuI. The measured isotope effects allow us to understand the corresponding temperature dependences, which we also report, to our knowledge for the first time, in the case of CuI. These results enable us to develop a more quantitative understanding of the phenomena mentioned for the three halides, and to interpret other anomalies reported for the temperature dependence of the absorption gap in copper and silver chalcogenides; similarities to the behavior observed for the copper chalcopyrites are also pointed out.Comment: 14 pages, 5 figures, submitted to Phys.

    Costs and Benefits of Labour Mobility between the EU and the Eastern Partnership Partner Countries - Country Report: Azerbaijan

    Full text link
    This Report is one of the six studies in the first phase of the EU project on the "Costs and Benefits of Labour Mobility between the EU and the Eastern Partnership Partner Countries". It aims at providing an informed view of the potential for increased migration flows and their consequences as a result of possible changes in the migration policies of the European Union with regard to Azerbaijan. The Report is comprised of 7 Chapters. Chapters 1 and 2 provide a discussion of relevant developments in the economy and labour market in the period since independence, with emphasis on developments over the last ten years or so. Chapter 3 provides a detailed discussion of trends in migration, and discusses the labour migration profile. Chapter 4 analyses remittances and their impact on income, investment and consumption. Chapter 5 provides a discussion of the available evidence on the costs and benefits of labour migration, emphasising the economic, social and demographic costs and consequences. Chapter 6 discusses current migration policies and institutions, while Chapter 7 discusses various factors that may be useful in forecasting key migration trends in the future

    Abstract The structural parameters (mоlеculаr mаss, plasticity, number оf chains' nеt and cross-linked molecules) of thermal vulcanizers on the basis of butadiene-nitrile rubber and polyvinyl chloride blends were studied by viscosity and sоl-gеl аnаlуsis methods. Аn alteration оf polаr groups content (-С≡N, С=О, С-Сl) and unsaturation оf thermal and thermal irradiated vulcanizers were investigated. According to alterations of residual deformation's accumulation, relaxation of tension and equilibrium modulus in air and in fuel, the properties оf elastomers were established at temperature (373-473K) and radiation (1000-2000 kGy) aging

    Hunt for new phenomena using large jet multiplicities and missing transverse momentum with ATLAS in 4.7 fb−1 of s√=7TeV proton-proton collisions

    Get PDF
    Results are presented of a search for new particles decaying to large numbers of jets in association with missing transverse momentum, using 4.7 fb−1 of pp collision data at s√=7TeV collected by the ATLAS experiment at the Large Hadron Collider in 2011. The event selection requires missing transverse momentum, no isolated electrons or muons, and from ≥6 to ≥9 jets. No evidence is found for physics beyond the Standard Model. The results are interpreted in the context of a MSUGRA/CMSSM supersymmetric model, where, for large universal scalar mass m 0, gluino masses smaller than 840 GeV are excluded at the 95% confidence level, extending previously published limits. Within a simplified model containing only a gluino octet and a neutralino, gluino masses smaller than 870 GeV are similarly excluded for neutralino masses below 100 GeV
