This paper examines the influence of polyacrylamide on soil biological activity. The results of the incubation experiment conducted in the laboratory are given. Carbon dioxide gas release or soil respiration is- one of the indicators of soil biological activity. Determination of the amount of released CO2 was carried out titrimetrically. Aliquots of alkali titrated continuously throughout the experiment. The graph presents the resulting effect of introducing polyacrylamide into the soil on release of total CO2. Finally the article presents conclusions and puts the problems of further study and system analysis of application of polya-crylamide in the active soil environment.

Introduction. The peculiarities of the functioning of non-profit organizations in Ukraine are identified. The accounting and information support of the analysis of the activity of public sector entities is considered. It is established that the reformation of accounting of public sector entities related to the introduction of the NP (C) BODS from January 1, 2017 requires a comprehensive analysis of the activities of budgetary institutions. It is noted that the analysis of the activity of a budgetary institution will provide full information about the real economic situation of the organization, reveal unused agricultural reserves for further development and ensure more efficient use of targeted state allocations. The object of research is the Main Department of Statistics in the Dnipropetrovsk region. The priori analysis of dynamic changes in cash inflows by type of income is carried out. It is proven that the use of only absolute indicators to estimate the dynamics of revenues is inappropriate. It is noted that the increase in the dynamics of cash inflows to a budgetary institution can testify only to the impact of inflationary processes. It is proposed to analyse the results of the organization's activities in a phased manner: analysis of dynamics and structure; analysis of the actual expenditures of the organization; assessment of the financial performance and determination of the size of the deficit or cash surplus. The algorithm of the complex analysis of the receipts of funds, incomes and expenditures of the budgetary institution is developed. It is established that the analysis of incomes and expenditures and financial results of a budget institution's activity is a necessary component of effective management of a public sector entity. Purpose. The article aims to evaluate the accounting and information support of the analysis of the activities of the public sector entities and to develop the stages of the analysis of the activity of the budget institution of the Main Department of Statistics in the Dnipropetrovsk region. Method (methodology). Method of system analysis, methods of causal analysis, table and graphical methods, dynamic series have been used in this research. Results. The theoretical synthesis and practical recommendations on the methodological aspects of the activities of non-profit organizations through the analysis of dynamics and the structure of cash flow; actual expenses of the organization; assessment of financial performance and determination of the size of the deficit or cash surplus have become the result of the research.

Carbon dioxide, CO2 accounts for most of the emission from all the types of greenhouse gasses in the world. The ability of CO2 to remain longer than other greenhouse gases and the convenience of producing CO2 has resulted in its high projection in a yearly manner. The prime factor for the emission of CO2 are from the actions of human beings. One such human act is the concrete industry. Total emissions from the concrete industry could therefore contribute as much as 8% of global CO2 emissions. Sequestered CO2 in concrete can provide an impact on reducing the carbon footprint and is also able to improve the compressive strength of concrete. During this process, the sequestered carbon dioxide chemically reacts with cement to produce a mineral, trapping carbon dioxide gas in the concrete. Hence, sequestering carbon dioxide gas in concrete does not only on a bigger scale reduces carbon footprint, but it also reduces the impact the construction industry has on the environment. This paper presents a detailed review on the chemical reaction that takes place during the sequestration of carbon dioxide and the research published on the effects of carbon dioxide sequestered concrete on its properties. The impact this process has on the concrete industry and the environment is discussed in this paper.

Abstract The aim of this research was to evaluate changes in soil quality associated with the tillage system applied with chosen parameters of soil biological properties. The long-term field experiments were located at a private farm in Rogów (Zamooeć region, E Poland) on a silt soil and at the Experimental Station in Laskowice (Wrocław region, S-W Poland) on a sandy loam soil. Soil samples were collected from 0-15 and 15-30 cm layers. Winter wheat was grown under traditional, reduced and no-tillage systems. The analyses included estimations of microbial biomass C and N content, microbial respiration rate, activity of dehydrogenase and arylsulfatase, and fluorescein diacetate hydrolysis. After eight years the effects of tillage on both soils were clearly noticed. In general, the less disturbing tillage systems enhanced the increase of soil biological activity by 15-40%, on average, than conventional tillage system. The significant correlations between microbial biomass, and/or enzyme activities with total organic C content indicate that concentration of organic C in soil environment plays an extremely important role in enhancing the stabilization and activity of soil microorganisms, and protection of an extracellular enzymes. The studied parameters of soil biological activity showed their sensitivity to tillage applied and may be considered as an useful indicators of soil quality in monitoring all conditions alter soil environment.

Abstract An accurate and precise automated method has been developed for the determination of lysine in grain hydrolysates. The enzyme L-lysine decarboxylase specifically catalyzes removal of the carboxyl group from L-lysine, producing an amine and carbon dioxide. This reaction has been automated. The carbon dioxide produced was selectively dialyzed into a stream of carbonate with phenolphthalein by a dialysis block containing a carbon dioxide gas dialysis membrane. Ground samples of grain (250 mg) were hydrolyzed 20 hr in 25 ml 6N HC1 at 110°C Aliquots were evaporated to dryness under nitrogen with low heat. The samples were redissolved in carbon dioxide-free water and the enzyme was suspended in pH 6.5 phosphate buffer. Analyses were made at 30/hr with a sample-to-wash ratio of 4:1. A standard curve with a range of 0 to 90 ppm lysine was expanded to full scale on the recorder. From the comparative height of each sample peak vs. the standard curve, the per cent lysine in the original sample can be calculated. Repeated analyses on 15 samples, 5 each of corn, mungbeans, and soybeans, by the automated method showed that the precision was good, and the results were in good agreement with classical ion exchange data. The automated method for lysine in corn has been used in our laboratory to analyze 1500–2000 corn samples each year for the last 5 years.
