Coccinelleidae: species diversity of Mozyr and estimation of representation in families in BOLD and GenBank
On the territory of Mozyr there are 18 species of Coccinellidae representatives thathad been collected and identified. Among them 4 species are indicated as rare for The Republic of Belarus, but 1 is included into the list of invasive alien species. The biotope № 1 includes 12 species of Coccinellidae. Nucleoid sequences of mitochondrial and nucleus genes of all analyzed species of Coccinellidae are deponed in BOLD and GenBank databases, but Coccinellidae from Belarus are poorly represented.На территории города Мозыря коллектировано и идентифицировано 18 видов кокцинеллид. Среди них 4 вида, редкие для Беларуси, а 1 – включен в список инвазивных чужеродных видов. В биотопе № 1 отмечено 12 видов кокцинеллид. В BOLD и GenBank депонированы нуклеотидные последовательности митохондриальных и ядерных генов всех анализируемых видов кокцинеллид. Кокцинеллиды из Беларуси очень плохо представлены
Development of the Experimental Scheme for Methanation Process
AbstractThe aim of this study is to develop an experimental scheme for realization of methanation reaction (CO2 + 4H2 → CH4 + 2H2O) realization. The existing experimental stands show that there are many factors and reaction parameters that may negatively act on CO2 conversion. The highest CO2 conversion rates are achieved at the temperature range of 300–400°C. Methane production efficiency also depends on reactor's space velocity, reaction's stoichiometry, catalyst's surface area and type. Nickel and Ruthenium are the most popular catalysts. Gas contaminants (like NO2, O2 and SO2) which may be in exhaust flow, act negatively on the reaction. According to this great amount of aspects acting on methanation process positive outcome special scheme was developed. It combines not only inlet gas properties, proper catalyst or reactor design selection, but also technical aspects such as preheating/mixing chamber and condensing unit design. This summarizing scheme will be used for real methnation reactor design in the future studies
The Investment climate in Latvia's, Lithuania's and Belarus's cross-border regions: the subjective-objective assessment
As the world experience indicates, the favourableness of investment climare or, in other words, a region’s entrepreneurial environment determines a region’s sustainable development. First assessments of investment climate were developed and applied by western experts in the middle of the 1960s. They were based on the subjective assessment of countries’ characteristics. The further development of the methodology for comparative assessment of countries’ investment climate started to expand and complicate the system of characteristics assessed by experts, and to introduce objective statistical indexes. In recent decades, more research into investment climate at the level of regions appeared, as a result of the understanding of a specific and unique character of regional features, as well as its dramatic differences from the country as a whole. It is possible to distinguish objective, subjective, and subjective-objective metholologies for assessment of investment climate. According to the outcomes of the subjective-objective assessment of the investment climate in Latvia’s (Latgale), Lithuania’s (Vilnius, Alytus, Utena, Panevezys, and Kaunas counties), and Belarus’s (Vitebsk, Grodno, Minsk, Brest oblasts, and Minsk city) cross-border regions, the regions under study were divided into 4 groups in accordance with W.Zapf’s Well-being Typology Matrix: 1) low objective and subjective indicators - “Deprivation”, 2) low objective indicators and high subjective indicators - “Adaptation”, 3) high objective indicators and low subjective indicators – “Dissonance”, 4) high objective and subjective indicators – “Well-being”
The Role of green economy in sustainable development (case study: the EU states)
The analysis of various “green” concepts has historically been linked to a broader discussion of the relationship between sustainable development and the environment. Some authors believe that the solution to the problem of the impact on the planet’s environment is to reduce the level of economic activity, which would mean severe restrictions in the use of resources. Others think that economic activity can continue to grow, but with less impact on the environment; some experts claim that it is quite possible to achieve a balance between economic growth and care for the planet and people. In this context, it is necessary to use a new paradigm that clearly states that "environment" and" economic growth" cannot be seen as conflicting goals, which is confirmed by the authors of the article who studied the situation in the EU countries in the period 2016-2017
