Enhanced oil recovery in mature fields can be implemented using chemical flooding with the addition of surfactants using surfactant-polymer (SP) or alkaline-surfactant-polymer (ASP) flooding. Chemical flooding design is implemented taking into account reservoir conditions and composition of reservoir fluids. The surfactant in the oil-displacing formulation allows changing the rock wettability, reducing the interfacial tension, increasing the capillary number, and forming an oil emulsion, which provides a significant increase in the efficiency of oil displacement. The article is devoted with a comprehensive study of the formed emulsion phase as a stage of laboratory selection of surfactant for SP or ASP composition. In this work, the influence of aqueous phase salinity level and the surfactant concentration in the displacing solution on the characteristics of the resulting emulsion was studied. It was shown that, according to the characteristics of the emulsion, it is possible to determine the area of optimal salinity and the range of surfactant concentrations that provide increased oil displacement. The data received show the possibility of predicting the area of effectiveness of ASP and SP formulations based on the characteristics of the resulting emulsion.

AbstractPlatelets express ABH antigens, which can adversely effect platelet transfusion recovery and survival in ABH-incompatible recipients. To date, there has been no large, comprehensive study comparing specific donor factors with ABH expression on platelet membranes and glycoconjugates. We studied ABH expression in 166 group A apheresis platelet donors by flow cytometry, Western blotting, and thin layer chromatography relative to donor age, sex, A1/A2 subgroup, and Lewis phenotype. Overall, A antigen on platelet membranes, glycoproteins, and glycosphingolipids was linked to an A1 red blood cell (RBC) phenotype. Among A1 donors, platelet ABH varied significantly between donors (0%-87%). Intradonor variability, however, was minimal, suggesting that platelet ABH expression is a stable, donor-specific characteristic, with 5% of A1 donors typing as either ABH high- or low-expressers. Group A2 donors, in contrast, possessed a Bombay-like phenotype, lacking both A and H antigens. Unlike RBCs, ABH expression on platelets may be determined primarily by H-glycosyltransferase (FUT1) activity. Identification of A2 and A1 low expressers may increase the availability and selection of crossmatched and HLA-matched platelets. Platelets from group A2 may also be a superior product for patients undergoing A/O major mismatch allogeneic progenitor cell transplantation. (Blood. 2005;105:3356-3364)

Newly created “Garaja” variety and the forms with lower lever of tanin introduced from ICARDA will allow widening of the field of Vicia Faba culture. Until present, culture of Vicia Faba in Azerbaijan was limited to household. In Azerbaijan, the sowing of vegetable beans does not have much production value. The culture is mainly used for research purposes and is cultivated in small areas, like garden. Therefore, the study of the morphobiological features of plants of the prospective variety in each region and the comprehensive study of the genetic resources of culture is relevant. The article is devoted to the results of a study of the local gene pool of horse or fodder beans and materials from ICARDA. Yield and analysis of crop structure, disease resistance were analyzed. Since samples with a low level of harmful substances are new for our republic. These studies are an important initial study for the subsequent production of new varieties. We hope that this will lead to an increase in the acreage of legumes in our republic.

There is a lack of an efficient systematic approach to the selection of appropriate construction methods for modern building systems. Identifying key criteria is necessary to help decision-makers in implementing the principles of this process. The present article was conduct for the same purpose. In this article, after reviewing of the literature, we found that construction experts’ opinions did not consider until now. Thus, we considered the opinion of experts in the field of the construction industry (Technical and executive specialists of the Afghanistan’s Ministry of Urban Development and Housing, Technical and executive specialists of the Kabul Municipality and Omran Houlding Group). For identifying key criteria, “64” criteria have been extracted that affect the selection of modern building systems and are classified into “six” economic, qualitative, social, environmental, executive and technical groups. A comprehensive study conducted through the distribution of questionnaires. The collected data were analysed using SPSS statistical software; the main criteria ranked by using “Friedman’s statistical test”. Based on the results of statistical tests, 18 criteria were determined and ranked as fundamental criteria. Therefore, paying attention to these criteria for the selection of appropriate construction methods for modern building systems can help experts in the country of Afghanistan.

Relevant in the selection of each crop, including watermelon is a comprehensive study of the source material to identify sources of valuable traits and include them in the selection process in order to expand the genetic diversity of the culture. According to the results of research, to create a new source material for heterosis selection of watermelon, screening and monitoring of the vegetation period duration (number of days from germination to ripening) and its components 118 (101 varieties, 17 hybrids) genotypes of watermelon in the forest-steppe of Ukraine have been conducted. Research methods are generally accepted: field experiment, observation, accounting, analysis, statistical. According to the results of determining the duration of the components of the vegetation period, the samples were divided into five groups of ripeness: early (65–80 days) – 80 (68 %), medium-early (81–85 days) – 14 (12 %), medium (86–95 days) – 18 (15 %), medium-late (96–105 days) – 4 (3 %) and late (106 days) – 2 (2 %). Variety-samples, selected by morphological and economically valuable characteristics, belong mainly (80 %) to early and medium-early. Only 6 % of genotypes belong to the medium-late and late-ripening groups. 52 samples with the smallest separate interphase periods were isolated. According to the results of the research, 8 sources with the high early ripeness were identified, the vegetation period of which was 66–70 days: Yellow early 108105 (66 days), Karapuz 108109, Surprise 108121 (67 days), Gift of the sun 108109, Lezheboka honey 108116, Thailand №1 108153 ( 69 days), Sweet Diamond 107874, Northern Lights 108127 (70 days).

The article is devoted to the analysis of the essence of integrated research during the judicial and technical expertise to establish the prostitution of documents. The attention is drawn to the fact that the forensic examination with the establishment of the preparation of documents is the most difficult among other species of this kind of examinations and to be complex. The authors consider the peculiarities of this type of expertise and emphasizes that such examinations have difficulty in carrying out the use of special equipment and physicochemical research methods. The paths of determining the preparation of the paperwork are emphasized: determining the specific time of manufacture of each of the details with a further comparison of the results obtained among themselves; establishing conformity between the time of signature and handwritten records; the printing time of printing and text printing time, establish a chronological sequence of details in the document. It was concluded that the decision of the expert problem with establishing the prescription of the document requires the use of so-called "destructive methods". The main complexity of the examination of the process of making the preparation of the document is that when conducting any actions with a document (cutting, selection of ink samples), the document can be fully or partially destroyed. In this regard, expert institutions that take an obligation to carry out such examinations, pay attention to the ability to damage the document and in this connection declare a relevant request for permission to carry out such actions. Such permission should be in the document on the appointment of expertise or in the letter. Attention is drawn to the fact that not the provision of information about the time of receipt of the document may lead to the impossibility of determining the prescription of the document. After a long time and complex research process, the expert is forced to give a conclusion "is not possible."

Abstract Currently, the methods used for sampling soil do not meet modern requirements when conducting comprehensive studies of ecological state of soils. Stratified sampling of soil samples does not allow us to judge the gradients of distribution of agrochemical parameters and microbial communities of surface soil layer in natural landscapes. The use of method of GPS positioning of equidistant points of surface layer of soil in a comprehensive study of agrochemical parameters of soil, the composition of microbial communities of landscape makes it possible to draw up a summary map-scheme (GIS). The article analyzes methodological features of selection of soil samples for agrochemical, bacteriological, and molecular biological analysis. Using example of southern alkaline chernozem with gradient of pH distribution from 7.5 to 8.5 units, the distribution of microbial communities and agrochemical parameters in surface layer of soil of a perennial fallow is shown. The range of changes in agrochemical indicators on site with an area of 1 ha for organic matter was (1.4 ± 0.3% - 5.4 ± 0.5%), ammonium (12.3 ± 1.2 - 26.7 ± 2.7 mg/kg), and nitrate nitrogen (0.9 ± 0.1 - 3.9 ± 0.6 mg/kg). The change in microbial communities corresponded to gradient of soil agrochemical parameters.

A comprehensive study of theoretical atomic absorbances has been made for most analytically useful elements, the only exceptions being the rare earths. These data have been compared with experimentally determined atomic absorbances in many cases. The importance of the low lying energy levels has been emphasized as well as the need for better atomic transition probability data. The choice of analysis line is discussed from both the theoretical and experimental points of view, and tables of relative atomic absorbances are given with their temperature variations where appropriate.
