THE RESEARCH OF PARAMETERS OF WOODEN CHIP COLORING

abstract 1311707006 issue 131 pp. 45 – 55 29.09.2017 ru 609
This work presents main kinds of colourants and methods of painting wood particles. Based on wood structure analysis, it was revealed that hard wood, possessing tracheides and vessels as conducting elements, have the optimal capacity for coloration, in comparison with coniferous trees. A methodology was developed of cloning wooden particles, in the form of chips, with forced immersion in order to obtain established parameters of saturation and brightness. The experiments were conducted with chips of 15-50 mm long, 5-20 mm wide and 3-7 mm thick. The composition of colouring agent included water, acetic acid, and water-emulsion colourants of different types and colours (№1 – colour code (red, yellow, and brown) №2 – colorant (lilac and orange) and №3 – paint). Experience has shown the needed concentration of liquors and mass percentage of compounding ingredients. The research was undertaken to study concentration dependence on the time of allowance and saturation. In consequence of colouring experimental batches of chips, a painting saturation of 4-9 points was obtained at the allowance of 120 and 140 seconds. Dependence of brightness from solubility was determined, with high correlation between given parameters on Pearson Criteria (more than 0.9). Comparative analysis made it possible to discover that the better colouring of particles is created with the red paint. In this case maximum colouring effect is achieved with liquor of water-emulsion paint. Subsequent to the experimental results, a design of installation for colouring wooden particles was developed and patented

abstract 1191605077 issue 119 pp. 1089 – 1098 31.05.2016 ru 612
The article describes the sources of noise Yeisk thermal power plant (TPP) in excess of the permissible sound pressure levels in homes on the street. Gorky, 25. Eisk TPP is located near the residential area, where the permissible noise level standards adopted much more stringent than in the power plants. Prolonged exposure to noise leads to human disease noise disease. The scheme of movement of exhaust gases from the thermal power plant generating units Yeisk. Analysis of measurements of noise characteristics of main and auxiliary equipment showed that one of the main sources are sectioned estuaries double-barrel pipe height of 27 m and slices estuaries pipes emergency explosive valves flues installed on the roof at a height of 17 m. The previous Noise reduction nozzles that emit noise uniformly in all directions are replaced by advanced, whose index changed direction estuaries sections double-barrel tubes. This will change the level of radiated noise in residential development. If you change the angle of orientation of 135°-180°, the noise level in residential construction decreased by 7-10 dB.

APPLICATION OF THE INFORMATION THEORY AND COGNITIVE TECHNOLOGIES FOR SOLVING PROBLEMS OF GENETICS (on the example of calculation of the amount of information in the genes about characteristics and properties of the various indigenous grape varieties)

abstract 1211607003 issue 121 pp. 116 – 165 30.09.2016 ru 613
It is well known that genetics studies the mechanisms of variation/heredity and widely uses the concept of "genetic information". While genetics considers the information as the content of the genetic code - structure of DNA and RNA included in the cell of a living organism. Genetics examines the mechanisms of recording, copying, readout of genetic information, the possibility of its modification and its influence on the characteristics and properties of the organism. In conversational and scientific language we know phrases, such as "Genes contain information about the characteristics/properties of the body." Paradoxically, we see no attempts to determine the amount of information contained in specific genes on specific characteristics or phenotypic properties of the organism. It would seem that the application of information theory in genetics is a completely natural and suggests itself. More strange that there are practically no works devoted to the application of information theory for solving problems of genetics. This article is intended, to some extent, to fill this gap on the example of calculating the amount of information in the genes of the characteristics or properties of different grape varieties. It examines the application of automated system-cognitive analysis (ASC-analysis), its mathematical model – system of information theory and software tools – intellectual system called "Eidos" for solving one of the important tasks of genetics: determine the amount of information contained in the genes on various phenotypic characteristics/properties of the grapes. To solve this problem, we perform the following steps: 1) cognitive-targeted structuring of the subject area; 2) the formalization of the subject area, i.e. development of classification and descriptive dials and graduations and training samples; 3) synthesis and verification of information model, reflecting the amount of information in the genes on the phenotypic characteristics/properties (multiparameter typing); 4) displaying the information about the genetic determination system of phenotypic characteristics/properties (SWOT analysis of Fennovoima); 5) displaying the information about the strength and direction of influence of a specific gene on phenotypic characteristics/properties (SWOT-diagrams of genes); 6) the solution to the problem of system identification phenotypic characteristics/properties by the presence of certain genes; 7) quantification of the similarities-differences of the various phenotypic characteristics/properties, upon determination system genes. A specific phenotypic property (or characteristic) is regarded as a noisy genetic text, including genetic information about the true gene property (clean signal) and the noise that distorts this information due to the random effects of the environment. The software tool of the ask-analysis which is "Eidos" intellectual system provides the noise suppression and the selection of true signal

PROSPECTS OF RENEWED POWER

abstract 1241610093 issue 124 pp. 1402 – 1414 30.12.2016 ru 616
The article considers the main types of wind and solar electric installations, and provides a comparative analysis of the renewable energy potential of the Krasnodar region. Currently, people of the Earth cannot live without electricity. Production and consumption of electricity is constantly increasing, and the cost of it is constantly becoming more expensive. The cost of oil production (cost to get oil out of the ground) increases constantly. The cost of electricity is going up because the cost of basic materials, such as copper, is at an unprecedented high level. Such alternative energy sources, such as solar and wind, are real solutions to these problems, moreover, the cost of "traditional" energy sources will only increase. To date, the most popular and invest renewable energy sources are the solar and wind power. Solar energy in the Krasnodar region is more profitable than wind one, despite the fact that the production of solar installations is more expensive. But every year the price of solar energy is reduced and soon will be equal to the price of wind energy, and science and technology do not stand still, so when there is such an abundance of sunlight in the Krasnodar region, the solar installation will pay off much faster

NEW TECHNICAL SOLUTIONS FOR A SEPARATION OF THE ORGANS OF POTATO MACHINERY

abstract 1241610018 issue 124 pp. 346 – 365 30.12.2016 ru 619
One of the promising directions of development of agriculture of the Russian Federation is to increase the production, improve the quality and decrease the cost of potato cultivation. Annual cleaning is one of the most intense and costly in transport and technological processes. Potatoes - blending high culture and very picky about cleaning. The highest yields and income from potato production get where embedded technology to optimize energy and labor costs. The main (though not only) the special technical means used during machine harvesting potatoes, are potato harvesters. The main problem when cleaning is a problem of balancing conflicting requirements to the process and possibilities of agricultural machinery. Including increasing the purity of the tubers in the container with one hand, minimization of losses and damages of tubers on the other hand, when the performance of equipment. In this article we propose a circuit-design solution separating the working body of the potato harvester that allow for cleaning to significantly reduce the amount of traumatized potatoes in the process of separating soil and vegetable impurities, creating the preconditions for the elimination of damage to the tubers on the hard side of the working bodies of harvesting machines. Informed choice and timely use of plug-in modules (separating working bodies) in modern potato harvesting machines at work in specific climatic conditions allows them to fully match the list of regulated agronomic requirements. Thus, the creation of new science-based technical solutions for a separation of the organs of potato harvesters is an actual scientific-technical task, which makes a significant contribution to the development of the country

THE YIELD AND COMPOSITION OF ESSENTIAL OIL FROM SPLIT CORIANDER FRUITS

abstract 1181604049 issue 118 pp. 827 – 839 29.04.2016 ru 620
The article studies dynamics of losses and the change of composition of essential oil from split coriander fruits. It is found, that in the fractions of split fruits, extracted from long-stored commercial lots of raw materials, mass fraction of essential oil is two or three times lower than in whole fruits. In the composition of essential oil from split fruits the content of valuable components - linalool, geraniol, geranyl acetate is slightly higher, and the content of undesirable hydrocarbons and camphor is lower. It is shown that from freshly split fruits, which were stored in a thin layer in the open air, the oil was intensively lost in the first three days, the losses reached 86 %. At the same time, the composition of the oil changed: the content of most volatile components - hydrocarbons decreased several times and the content of high-boiling linalool, geraniol, geranyl acetate significantly increased, which increased the quality of the oil smell. The change of composition is determined not only by the ratio of components volatility. The content of relatively high boiling camphor almost half decreased. This could be associated with less ability of fruit tissue to sorb and the ability of camphor to be easily sublimated. The content of volatile n-cymene over time increased with a simultaneous decrease in the content of γ– terpinene, which confirmed predominantly chemical way of n-cymene accumulation in coriander essential oil in conditions conducive to oxidation. It is recommended to separate the split fruits as soon as the raw materials come to the plant and to process immediately. Essential oil from split fruits can be used to adjust the composition of individual lots of oil in order to improve their quality, and to provide extraction of valuable components – linalool and geraniol by vacuum rectification method
