In modern economic theory, there is no complete classification of innovative approaches to the management of knowledge-intensive and high-tech companies and enterprises. Among these approaches, we can highlight situational, structural, process, functional and project-based approaches. The project-oriented approach, as a purposeful method of future systems forming, is a kind of continuation of the process approach; however, it gives priority not to the process, but to the project, as the main production, innovation and competing business unit. This article provides a brief overview of carried out research in this subject area, analyzes the advantages and opportunities of existing project management validity models, and suggests the author's approach of building a model for identifying and evaluating the potential of modern project-oriented companies and enterprises. This article also shows that the economic efficiency of such companies and enterprises achieving by using the project-based method both in the integrated system of strategic management and in the main production activities. This leads to an increase in their ability to choose the right way of operational decision-making, contributes to the installation of advanced technological and technical equipment, and accelerates the commissioning of new production facilities
Progress in crop production depends on many factors; including the important measure is the protection from pathogenic microorganisms. Various chemicals are used to control phytopathogens, such as natural and artificially synthesized ones. Natural compounds are more environmentally friendly, in most cases less toxic and quickly destroyed. The purpose of this work was to find strains of actinobacteria that have antifungal activity and are considered by us as possible sources of antifungal compounds for agricultural purposes. We selected 10 strains of actinobacteria that were isolated from typical regions of Russia. These strains were active against the fungal test strains Saccharomyces cerevisiae RIA 259 and Aspergillus niger INA 00760 when deep cultured. To determine the activity of selected actinobacteria against phytopathogenic fungi, 6 strains isolated from affected plants were used as tests. Morphological and genetic analysis methods have shown that the selected actinobacteria strains belong to two genera and are represented by the following species: Nocardia soli, Streptomyces antibioticus, S. bottropensis, S. chartreusis, S. chromofuscus, S. hydrogenans (2 isolates), S. lusitanus, S. netropsis, S. peucetius. Phytopathogenic fungi are represented by the following species: Fusarium armeniacum (2 isolates), Fusarium culmorum, Alternaria tenuissima (2 isolates), Bipolaris sorokiniana. As a result, it was found that under conditions of submerged cultivation on nutrient media, actibacteria form substances that inhibit the growth of all phytopathogenic tests used in the experiment. The representatives of species N. soli INA 01217, S.chromofuscus INA 01211, S. lusitanus INA 01218, S. netropsis INA 01190 and S. peucetius INA 01255 have not been described as having antifungal activity previously, so we consider them to be the most promising for chemical research to identify new antifungal antibiotics
The article presents a comparative assessment of the meat productivity of young cattle of the two most common intensive meat breeds in the Russian Federation (Aberdeen Angus and Hereford) in comparison with the most numerous native in the South of the country domestic breed, which is Kalmyk. Intensive rearing from 9 to 18 months of age was carried out in the conditions of industrial fattening complex on rations not containing juicy forages. In the process of 273-day intensive rearing, in bulls of the tested breeds average daily live weight gains from 1455 to 1526 grams were achieved. During this period, an absolute increase was obtained in Aberdeen-Angus bulls-416.6 kg, in peers of Hereford and Kalmyk breeds-413.6 and 397.2 kg. The highest pre-slaughter live weight and slaughter rates were noted in Aberdeen-Angus bulls, having a yield of a pair carcass of 59.4 % and a slaughter yield of 62.8 %. The meat of Aberdeen-Angus bulls has the highest content of fat and dry matter, but they have less protein, lower pH and moisture binding capacity and a higher loss of meat juice during cooking, compared with the bulls of the Kalmyk breed. It was confirmed that the coefficients of transformation of protein and energy into products are closely related to the intensity of growth and weight of the carcass. The most effective of these indicators were in bulls of Aberdeen-Angus, then Hereford and Kalmyk breeds. A similar pattern between the breeds was manifested in terms of profitability and cost recovery
One of the key problems facing medicine is the correct diagnosis given in a timely manner. For all the existence of medicine, humanity has accumulated a lot of knowledge in this area. According to this knowledge, new specialists are trained. But there is so much information that it is sometimes impossible to find the right information in it in time, and this can cost the person who came to see a doctor very expensive. In this specialist comes to the rescue computer. Information technologies, training in information bases perfectly cope with the task of identifying the disease and providing the most appropriate information
The problems of import substitution, resource features of the agrarian economy, through which you can generate significant competitive advantage, are discussed. It is noted that low abroad interest rates on loans create obvious unequal starting opportunities throughout the domestic business. As a result the cost of imported food in value chain terms reached in our country an enormous rate of $45 billion and that government realized the need of strengthening of food security, transferring of production of traditional kinds of products which form the basis of consumption of the population in our country, to the domestic market. It is noted that we need temporary moderate state protectionism and protection of the domestic market with the aim of modernizing the economy, attracting investors in the important field of production with high risks. The main problems and solutions that will help to further successful implementation of this strategy in the sectors of our economy are highlighted. It is noted that our region has the most effecting rural industrial structure, the best country’s climate, enlarged crop rotation, cheap labor resources, extensive experience in agribusiness. It is proposed to perform a set of measures to reduce systemic risks in agribusiness
Video camera is the source of the image of the object selected for observation or protection. Video cameras are used to collect information, being sometimes indispensable device. When analyzing images, it is important that the condition for the accurate operation of the video frame transmission system is fulfilled. All cameras have a slight delay in image transmission. For image analysis, it is important to know the delay time
In the production of seeds of sugar beet hybrids, based on cytoplasmic male sterility (CMS), we use single-fruited male sterile (MS) and ungrown fertile pollinator (Fp) plants as components of the cross. Sugar beet has a two-year development cycle. In the first year, root crops intended for growing seeds are formed, in the second year, a rosette of leaves grows from the vegetative roots of the root crop, and flowering stems grow from the generative buds. The article presents the planting method for seed production of MS of sugar beet hybrids under irrigation during summer thickened sowing. This method allows you to grow root crops-plugs with a yield factor of planting material 1: 6, 1: 7. We have also considered technological methods for growing root crops-plugs of the parent components of MS sugar beet hybrids on irrigation. The features of moisture supply and mineral nutrition systems were studied. The techniques of sowing technology and the formation of density of planting, care of crops, as well as methods for the protection, harvesting and storage of mother beets, contributing to the production of high-quality planting material, have been developed
In this work we have given the analysis of the literary data confirming positive experience of impact of the hydrocarbon substance of growth (HSG) on viability of seeds, resilience, growth of plants, and productivity of various crops. It is shown that the basic experimental data belong to the 60th of the XX century. At the same time, works on application of HSG have been generalized for the first time in the collection of works of the Academy of Sciences of the Azerbaijani SSR by Institute of soil science and agrochemistry. HSG represents the by-product of petro processing received at sulphuric acid cleaning of diesel fuel with further processing with alkaline solution of NaOH. It includes mainly mixture of sodium salts of naphthenic acids. On the basis of literary data and own probes it is established that for each culture there is optimum very small concentration of HSG (0.005-0.01%), processing by solution of which makes positive impact on viability, growth and development of crops. The results of probes of blood formation of animals [8] and growth of mass of birds allow considering HSG ecologically safe. We have also presented the results of pilot study of impact of pre-seeding processing of seeds of wheat and peas by water solutions of the hydrocarbon growth substance (HSG) on their morpho-physiological parameters. The most effective concentration of HSG for processing of seeds of spring wheat of grade "Saratov" and grade peas "Alpha" is revealed. It is shown that the stimulator in concentration of 0.005-0.01% proves as stimulator of crop growth. It follows that degree of efficiency of action of HSG on improvement of development and increase in productivity of agricultural products from use of this drug is quite high. Considering that the stimulator can be received at insignificant expenses as a waste product of the purified diesel fuels, its application in agriculture is economically justified
The instrumental methods of economics include the Monte Carlo method (statistical simulations method). It is widely used in the development, study and application of mathematical research methods in econometrics, applied statistics, organizational and economic modeling, in the development and making management decisions, in the basis of simulation modeling. The new paradigm of mathematical research methods developed by us is based on the use of the Monte Carlo method. In mathematical statistics, limit theorems on the asymptotic behavior of the considered random values were obtained for many methods of data analysis with an unlimited increase in sample volumes. The next step is to study the properties of these random values for finite sample sizes. For such a study, the Monte-Carlo method is used. In this article, we use this method to study the properties of statistical criteria for testing the homogeneity of two independent samples. We considered the most used in the analysis of real data criteria - Cramer-Welch, which coincides with the equality of the sample sizes with Student's criterion; Lord, Wilcoxon (Mann-Whitney), Wolfowitz, Van der Waerden, Smirnov, type omega-square (Lehmann-Rosenblatt). The Monte Carlo method allows us to estimate the rates of convergence of distributions of criteria statistics to the limits, to compare the properties of the criteria for finite sample sizes. To use the Monte Carlo method, it is necessary to select the distribution functions of the elements of the two samples. For this purpose, normal and Weibull – Gnedenko distributions are used. The recommendation was received: to test the hypothesis of coincidence of distribution functions of two samples, it is advisable to use the Lehmann-Rosenblatt (type omega-square) test. If there is reason to assume that the distributions differ mainly by the shift, then the Wilcoxon test and Van der Waerden criteria can also be used. However, even in this case, the omega-square type test may be more powerful. In the general case, besides the Lehmann-Rosenblatt criterion, the use of the Smirnov criterion is permissible, although for this criterion the real level of significance may differ from the nominal level of significance. We sstudied the frequency of discrepancies of statistical findings on different criteria
The article introduces a study on the creation of a simulated physical and mathematical model of the working process of a strip thrower, throwing soil in a directed flow. The problem solved with the help of this work is aimed at optimizing the cutting and ejection process in a given direction of the soil with minimal energy consumption with a maximum emission range. The article describes a methodology for calculating the milling thrower, which is oriented to the formation of the required amount of soil to create a mineralized strip at the edge of a forest bottom fire. Improving and realizing the full reproduction of physical and mathematical models using process simulations, you can save resources on the development of forestry aggregates. The study presents a productive method of processing soil with milling cutters, which helps to reduce energy consumption due to the formation of oriented mineralized flows of soil. For a physical and mathematical description of the process, a simulation program has been compiled that allows you to test the specific task of minimizing energy consumption at a maximum distance of soil discharge with a constant flow density to the rotational speed of the milling throwers
