COLOR- SENSITIZED SOLAR ELEMENTS
DescriptionPhotovoltaic devices are a promising solution to the energy crisis, because they generate electricity directly from sunlight, without producing CO2. While color-sensitized batteries are the most studied element, mainly due to its low cost and high efficiency solar energy conversion into electricity. Until recently, the color-sensitized solar cells performance was less than 1%, however, the use of titanium dioxide as the anode material have greatly raised their efficiency. The advantages of titanium dioxide is primarily in the low cost, but its use provides high light capture efficiency, with external quantum efficiency (efficiency incident photon - charge), usually in the range of 60-90% using nanocrystal forms in comparison with

COLOR WORDS IN THE LANGUAGE OF ECONOMICS
10.00.00 Philological sciences
DescriptionThe article is fulfilled in the frames of modern linguistic studies where the cognitive aspects of language activities are actively studied, concept researches are conducted and is devoted to the study of color words in the design of color picture of the world of different language cultures and their role and function in formation of special language terminology. The authors analyze compound terms and their definitions of a new emerging trend of the economy – green economy, borrowed from the materials of UN organizations and Institute of Green Economy and reveal that the color word green participates in terminology formation due to metaphoric use, as an indirect nomination that gives way to sense increment. Color words bear assessment charge that is realized in terms formation through complex attributive combinations. The ambivalence of the semantics of color is demonstrated through opposite meanings and this allows conclusion that color words are connected with emotional and volitional state of a person, society and that they are perceived in a figurative, non-color, but psychological, emotional meaning and due to this ability they are able to form mental formation in professional field

Description
The expediency of the «direct-costing» system in Russian organizations as a whole is considered in the article, as well as the necessity of using direct-costing in the organization of the ASTC «RIS» with rice production and sale as main activity. The advantages and disadvantages of using this system in the context of the analysis of the ASTC «RIS» activities are considered; the essence of the system «direct costing» is revealed. Besides, the authors have extended the need of presenting the cost accounting organization characteristics in general and its comparison with methods of accounting in the use of «direct-costing». The necessity of the introduction of this system in accounting organization in the Russian organizations is proved. With this aim, an analysis was conducted of rice prime cost changes using the system of «directcosting»; the authors have determined the break-even point, selling price and provisory profitability. All the performance indicators of the organization show the need for the introduction of «direct-costing» system in ASTC «RIS». Considering the possibility of implementing the «direct-costing» system in parallel with the traditional cost accounting system, the authors give characteristics to operations management and selling profitability, that allows to be more responsive to market conditions in pricing and to assess the contribution of each division in the organization of ASTC «RIS» in general, aimed at improving the efficiency of rice production

A CENTRIFUGAL DEVICE WITH SUPPLY OF MATERIAL ALONG SHOVELS
DescriptionIntroduction of mineral fertilizers is performed by centrifugal devices. By quantity of disks, centrifugal devices distinguish one disk and two-disk. On the volume of capacities for storage of mineral fertilizers distinguish bunker and body. Bunker contains volume from 0.5 to 1.5m3. Body has capacity more 2m3. Advantages of bunker centrifugal devices are noted. Material from the bunker moves on a centrifugal disk perpendicular to the rotation plane. At the time of material capture by shovels, crushing of particles and their reflection from shovels and the plane of a disk takes place. It leads to increase in unevenness of introduction of mineral fertilizers. At EMTP chair of the Kuban GAU the centrifugal device with supply of material along shovels is developed. The scheme of the centrifugal device is submitted. A device for introduction of mineral fertilizers contains the one-disk centrifugal device, the cone-shaped bunker and the cylindrical batcher. The batcher gate regulates supply of material on a disk. The technique of determination of design and technological data of the developed design is presented. The place of supply of material on a disk is regulated by rotation of the batcher round a vertical axis. The norm of supply of material on a disk changes the batcher gate. Preliminary control of a place of giving is made on model material with coefficient of friction of f 1. Under production conditions, turn of the batcher from initial situation is made depending on coefficient of friction of the f2 fertilizers. At f1 ˃ f2 turn of the batcher against the direction of rotation of a disk, and at f1 ≤ f2 turn of the batcher in the direction of rotation of a disk

CYCLICAL EFFECTS OF ACTINOMYCIN D ON THE BARLEY COLEOPTILES GROWTH
DescriptionIn cell biology, actinomycin D is shown to have the ability to inhibit transcription. Actinomycin D does this by binding DNA at the transcription initiation complex and preventing elongation of RNA chain by RNA polymerase. When soaking the seeds in a solution of actinomycin D, antibiotic blocks RNA synthesis and seed germination occurs at the expense of long-living RNA, available in the mature seed. In the article we present experimental data indicating that as storage seeds of winter barley are changing the action actinomycin D on the growth of coleoptiles. It is shown that actinomycin D at a concentration of 40 µg/ml in October reduced the growth, in December it was not authentically, and in February it was paradoxical amplified growing coleoptiles. We suggest the part of the actinomycin D fastened with growth inhibitor coleoptiles, whose structure changes during seed storage and increase the affinity of actinomicyn D to the inhibitors. At a concentration of 60 µg/ml actinomycin D effectively reduced of the coleoptiles growth. Suppression of seedlings roots growth was proportional to the concentration of the actinomycin D and exposure time

SPECIAL CASES OF INVERSE MATRICES
01.00.00 Physical-mathematical sciences
DescriptionThe inverse matrix for the square matrix A of order n with coefficients of some field exists, as it is known then and only then, when its determinant is not equal to zero. If the matrix A has a certain type (certain structure), then an inverse matrix A-1 should not have exactly the same structure. Therefore, it is interesting to describe such square matrices A, which have an inverse matrix A-1, having the same structure as the matrix A, under certain conditions. For example, a subdiagonal matrix with nonzero elements on the main diagonal has an inverse matrix over a field of characteristic zero, having also the form of subdiagonal matrix. Similarly, an inverse matrix towards symmetrical or skew-symmetric matrix is also symmetric or skew-symmetric accordingly. Also, the matrix inverse to non-degenerate (nonsingular) circulant will be a circulant itself, and finally, the matrix inverse to nonsingular quasdiagonal matrix D will be quasdiagonal itself, and will have the same partitioned structure as D. Thus, there is a problem of determining these types of nonsingular matrices that have an inverse matrix of the same type as a given matrix. In line with this problem in the present study it is determined such type of matrices for which an inverse matrix has the same type, at that the conditions are identified in explicit form, ensuring the nonsingularity of the matrix. The matrices of three orders are shown in detail. These results allow determining the characteristics of fields over which there are inverse matrices of the considered types
