We estimated the reduction in nitrogen outflow load from a paddy field that had a recycling irrigation facility and, by using a replacement cost method, evaluated the economic effect of nitrogen removal by the paddy field during the irrigation period in the Yoshinuma region of Tsukuba City, Japan. The recycling ratio of outflow water (proportion of outflow reused) was 13.5%. The nitrogen (N) outflow load was reduced by about 45 kg ha−1 by the N removal function of the paddy field and by about 39 kg ha−1 by the recycling irrigation facility. The paddy field equipped with a recycling irrigation facility as an N removal facility was valued at 32.6 million Japanese yen (JPY) ha−1 and 0.72 million JPY ha−1 per year, which compare it with the construction and maintenance costs, respectively, of a water quality improvement facility. The recycling irrigation facility was costed at 17.3 million JPY ha−1 for construction and 0.21 million JPY ha−1 for maintenance per year. The cost for constructing and maintaining a recycling irrigation facility was 53% of the value of the paddy field area equipped with a recycling irrigation facility as an N removal facility.

The purpose of this study was to clarify the nitrogen (N) purification capacity of a paddy field in a recycling irrigation system. Irrigation water was sampled at 12-h intervals during the irrigation period from April to September 2003. In addition, ponded water in a paddy field was collected at three points (inlet, centre and outlet). Total amounts of N were 30.7 kg ha−1 in inflow and 27.8 kg ha−1 in outflow. Thus, the net outflow load was −2.9 kg ha−1. The N removal rate constant when N removal is expressed as a 1st-order kinetic was 0.017–0.024 m d−1. This value is close to values of wetlands and paddy fields in the literature. We found a good correlation between recycling ratio and N removal effect. These results indicate that the recycling irrigation system accumulates N in the irrigation/drainage system, and thus the paddy field does a good job of water purification by removing N.

The article presents materials on the study of the possibility of reproduction and increase in the herd of highly productive cows through the use of embryo transplantation technology. The classical (in vivo) and more modern, developing (in vitro) methods of embryotransfer, their positive and negative sides are considered in detail. The possibility of accelerating the breeding process by using the method of transplantation, in which from one cow can be obtained from 10 to 100 calves, which will allow for 4-5 years, almost any herd (of any size and breed) with the help of biotechnology to turn into a cattle-breeding enterprise of the most modern level. At the same time, heifers obtained from unproductive cows can be used as "surrogate" mothers who are transplanted with the best donor embryos, which allows to obtain a full-fledged offspring adapted to local environmental conditions. A detailed scheme of obtaining, evaluation, storage, as well as the cost and economic effect of embryo transplantation was calculated, the market was evaluated, the required annual volume of transplants and the number of donor cows for large livestock farms were determined. As a positive example of "Scientific-production enterprise "Centre of biotechnology and embryo transfer" in 2014, implemented a project for accelerated replacement and genetic improvement of the dairy herd, engraftment averaged 57-69%, and the economic effect of the enterprise from getting a single animal by the method of embryo transfer, compared with imports of similar close in quality, ranged from 60 to 100 thousand rubles on his head. It is shown that it is necessary to organize at the state level a developed service for embryo transplantation to reduce the cost of embryo transfer and the possibility of creating in a short time in the country's own highly productive breeding nucleus of dairy and beef cattle, which will reduce, and in the future completely eliminate, import dependence on cattle products.

The efficiency of introducing probiotics based on strains of Bacillus subtilis, Bacillus licheniformis and their consortium in the amount of 150 g/t of feed into the diets of laying quails has been studied. The experiment lasting 182 days has been carried out on four groups of quails with 30 heads in each. The quails have been housed in the broiler battery in compliance with the required microclimate conditions. Quails of all groups have been received the main diet (compound feed) developed taking into account their age and physiological characteristics. The quails of the 1st, 2nd and 3rd experimental groups in addition to the main diet received probiotics (150 g/t compound feed) based on strains Bacillus subtilis, Bacillus licheniformis and their consortium, respectively. It has been found that feeding the laying quails of the consortium of strains Bacillus subtilis and Bacillus licheniformis had the most significant positive impact on their productive performance, it allowed to increase egg production by 7,81 %, egg laying intensity by 5,0 %, egg mass yield by 9,77 %, while reducing feed expenditures for 10 eggs by 13,35 %. The yield of hatching eggs has been increased by 7,03 %, hatchability of chickens from laid and fertilized eggs by 8,33 and 8,35 %, brooding waste decreased by 21,74 %. Hematological parameters of quails during the whole experiment were within the physiological norm. The economic effect calculated on the basis of data on the cost of compound feed, probiotics and the cost of sold eggs of quail laying was 14,56 % in the 3rd experimental group (in relation to the control group).

We studied nutrient balance in a paddy field that had a recycling irrigation system and evaluated the effect of the irrigation system on nutrient balance during the irrigation period, from April to August 2002. Chemical fertilizer was the main input of phosphorus; the soil absorbed about 56% of it. The amount of nitrogen supplied by the irrigation system was higher than in a representative paddy field, and the amount of nitrogen fertilizer used was decreased because the irrigation water was partly reused. About 20% of applied nitrogen was lost by denitrification. The net outflows of phosphorus and nitrogen were −0.37 and −3.98 kg ha−1, respectively. These results indicate that our study paddy field performed well in removing phosphorus and nitrogen compounds from runoff water. A recycling irrigation system can be considered an effective way of reducing the amounts of water and fertilizer used and reducing the outflow nutrients.

To achieve the objective with the claimed technical result, a method of fastening mine workings of predominantly rectangular cross-sectional shape with anchor bolts was used, while the applied task of reducing the heaving of soil rocks is to increase the efficiency of mine workings by ensuring that the mine workings. Ensuring the possibility of reliable and of good quality fortified rocks along the contour of making within the boundaries of the zone of possible collapse of rocks. The length of the soil anchors did not significantly affect the condition of the soil rocks. Consequently, that on the deformations and stresses both in the lateral and in the soils are not soil, but lateral anchors. The use of these technological developments will reduce the cost of conducting and maintaining workings by 7–10% with soil anchors (reducing maintenance costs by 7–10%) and will provide an economic effect of 10–15 thousand tenge per running meter of output.

Swamp land has a great potential to be developed as a paddy field area. However it has many constraints such as-phyrite (FeS2) at the depth of 30–60 cm and lack of soil nutrition. On the other hand, supply of marine clay from the sea which contains a lot of smektit clay mineral can be used to netralize this condition. Mud clay is very important for the development of rice root because it contains much nutrition and to enlarge the top of soil reducing the oxidation of phyrite. This study was conducted from January 2016 to June 2017 in swamp land area of Barito River of South Kalimantan. Data was collected by measuring the difference between maximum and minimum sea tide (tidal amplitude) and the deposition of mud clay. The results indicated that the distribution of mud clay deposit vary depends on the geography and the tidal amplitude of the zone. Zone VII has higher concenration of mud clay than the other one. The distribution pattern of mud clay deposit follows the parabola type, verticaly and horizontaly type, as well. Increasing of mud clay at all of the zone areas are not significantly effected by the daily tidal amplitude, only depends on climate condition/the season change.

The article considers modern aspects of the use, accounting and taxation of business cards, which are currently an integral part of communication and exchange of contacts in the business world. In particular, the essence of the concept of “business card” is studied, which is a carrier of information not only about the person-owner, but usually also contains information about the activities of the enterprise where its owner works. The classification of business cards into personal, business and corporate depending on their application and the information presented on them is systematized. Particular attention is paid to business cards, which are also a tool for advertising, as well as corporate, because, when they are distributed is the primary information to society, business partners about the company (company) and its activities. The authors substantiate why business cards are not an “additional benefit”, because they are issued to employees not for his personal purposes, but to achieve business goals of the employer: expanding customer base, increasing sales, making a profit, etc., in addition, companies do not give them in the property, but only oblige employees to use such cards during contacts with various participants in economic activity. Accordingly, the influence of such a decision on the process of taxation of the manufacture of this type of business cards is shown. The peculiarities of displaying information on the movement of business cards in the account, which requires their identification as “assets”, or rather – “stocks”, because they fully meet the criteria for defining these terms, presented in the legislation of Ukraine. Business cards are a controlled material resource of the enterprise, in which in the past certain funds or other stocks are invested, and in the future it is expected to receive from their distribution economic effect – benefit, it is an asset of the enterprise. Analytical accounts are offered to detail information on the cost of self-made or purchased business cards, which will facilitate the formation of clear management reports, will provide specific information for internal analysis. The sequence of reflection in the accounting of expenses at the time of transfer (write-off from the balance) of business cards depending on the center of responsibility with the use of certain primary documents is given.

In order to evaluate the effective of the hydrodynamic control of pumps and slice gates in plain river network on the water quality improvement, an optimal mathematic model of hydrodynamic controlling on the pumps and slice gates in plain river network was established by combining the water quality objective function and the cost objective function together. The cost function has been set as the main objective function, while the water quality objective function was simplified as the restrained condition for every required water quality index, through which the multi-objective optimization was transferred into a single-objective optimization. Then, this optimal model was solved by coupling the water environmental model with the hybrid genetic algorithm. The case study of Jiaxing river network shows that the proposed hydrodynamic controlling optimal model in this paper can develop the optimal water diversion scheme for water quality improvement and cut its cost. It works better compared to the traditional water quality objective function and can be used in the engineering practice.
