The aim of this study was to evaluate morphologic features, diagnostic qualifiers and enhance classification of alluvial-meadow soils in the floodplain of the Kur River within Azerbaijan. For this purpose, several soil pits were placed in the representative test areas and multiple soil samples collected within field campaigns (2014-2015). Based on the field and laboratory test data, the detailed soil maps of the test areas were compiled, and diversity of alluvial-meadow soils was classified as suborders (subtypes): alluvial-meadow primitive; alluvial-meadow layered (flaggy); alluvial-meadow dark and alluvial-meadow irrigated. It was found out that in the floodplains, local soil variability was predominantly attributed to not only alluvial sediments, but also water table, mineralization rate and salt content of underground water as well flood water play an important role. The mineralization of ground water is weak (1.40-3.70 g/l) and the concentration of hydro-carbonates (HCO3-) varies from 0.56 to 0.92 g/l. No salinization indication found in the profile of alluvial-meadow primitive and alluvial-meadow layered soils, while weak concentration (solid content = 0.40-0.54%) was found at a depth of 80-150 cm in the alluvial-meadow dark soil. Unlike other subtypes, alluvial-meadow dark soil is characterized with the higher biomass (green weight of top = 41.5 cwt/ha and green weight of underground = 142.3 cwt/ha), high mobility of humus substances with predominance of the 1st fraction of humin (20.0-28.1%) and fulvic acids (14.6-22.3%). The ratio of Cha : Cfa reaches 1.18-1.32. For the alluvial-meadow irrigated soil, the second fraction of humin acid (9.3-10.2%) and total content of humin acid ranges from 45.6 to 50.3%. The ratio of Cha : Cfa is larger (1.37-1.50). Depending on the lithology of alluvial sediments, the content of SiO2 and R2O3 varies in the ranges of 53.0-57.2% and 9,6-26,0%, respectively. For the alluvial-meadow dark soil, decomposition of alum silicates in alkaline hydrolysis is typical (8.7-9.0). The content of SiO2 and R2O3 varies between 47.8 and 50.6 %, and 19.7 and 21.6%, respectively. In the topsoil, of the irrigated soils in associated to washing out the content of Ca and CaO content (12.2-13.1%) increases in deeper horizons.

It is established that in pig farms of various forms of ownership the number of animals with violation of reproductive function makes from 11.7 to 39.7%. As a result of the clinical examination of the basic herd of pigs revealed that obstetric pathology occurs on average 40.1 percent of broodstock, with 26.7% of the sows in the period of pregnancy registered gestosis with a classical triad: hyperhydration, hypertension and proteinuria. Depending on the symptoms, there were 4 forms of pregnancy complications with gestosis with symptoms of anemia (38.4±1.89%), hepatopathy (27.8±1.2%), nephropathy (34.5±1.7%) and paraplegia (9.3±0.7% of pregnant sows). Diseases of pregnant sows were clinically manifested by events of oppression - loss of appetite, pallor of visible mucous membranes, soreness of palpable area of the liver, proteinuria, hypertension, disorders of the Central nervous system, calving mobility problems, yellowness of the eyeball. Morphometric studies of the placenta in the gestosis of pregnant sows evidence that the length of the umbilical cord, the mass of the maternal part of the placenta, the thickness and volume of the child part of the placenta is reduced to a statistically reliable magnitude, compared with similar indicators in clinically healthy pregnant sows. Noted a significant fluctuation of fetus-placental ratio with an inverse of value. There was a significant fluctuation of the fetal-placental coefficient with the opposite value, in piglets born from clinically healthy mothers. The functional status of newborns depends on the forming processes of the maternal and child placenta, as well as the morphological and physiological properties of the development of fruits, which is confirmed by an authentic decrease in the body weight of newborns by 30.0-40.0% and weakly expressed motor-food reflexes.

Morphophysiological parameters of hard and soft wheat genotypes depending on different water supply
Статья научная
To determine drought tolerance of 10 wheat varieties (3 durum and 7 bread) differing in architectonics, the research was performed under normal and drought conditions. The reduction in the plant height due to cultivation conditions rather than genetic properties of the genotypes occurred because of the decreasing length of upper internodes by 0.47-9.51%. Structural components of the product were determined. The greatest reduction in above-ground dry biomass per unit of the field was detected in Barakatli 95 and Garagylchyg 2 genotypes. The amounts of pigments were determined to evaluate the level of the photosynthetic apparatus development, its physiological state, formation and accumulation potential of the product. The content of chlorophyll a, b and carotenoids was determined during the grain forming, milk ripening, and wax ripening phases. Green plastids were broken down and chlorophyll content decreased under drought. Chlorophyll a content decreased more sharply compared with chlorophyll b. Chlorophyll a content decreased more sharply in all phases in the durum variety Barakatli 95 (during the phases, respectively, 19.7; 16.6 and 35.6%) and bread variety Gyrmyzy gul 1 (21.9; 15.3; 39.5%). Chlorophyll b amount decreased less in the durum variety Tartar (11.0; 7.30; 14.2%) and bread variety 4th FEFWSN-50 (4.83; 10.8; 9.20%). Amounts of the photosynthetic pigments were determined in various regions (Gobustan and Jalilabad Regional Experimental Stations). Chlorophyll a content decreased more in the Gyrmyzy gul 1 and Garagylchyg 2 varieties (in Gobustan: 2.302 and 2.979 mg/g fresh weight) in Jalilabad: 2.096 and 2.737 mg/g fresh weight) under rainfed conditions. Drought had a relatively less impact on chlorophyll a content in the Azamatli 95 and Gobustan varieties. Chlorophyll b content ranged from 0.033 to 2.398 mg/g fresh weight in Gobustan and from 0.057 to 2.175 mg/g fresh weight in Jalilabad, whereas the content of did not decrease.

Статья научная
This paper identifies the role of mythology in Spotted Dog Running Along the Seashore Novel by Ch. Aitmatov. The aim of the study is to apply mythological criticism to the novel, to find related myths and legends in the story, to interpret their roles, and to underline Aitmatov’s style of writing through his use of cultural mythology of certain folk. In order to complete the research on the topic, a critical analysis was done on the main myths of the novel. During the conduct of the analysis, it was revealed that the symbols used by the author do coincide with the world symbols. For example, in the book, Luvr duck symbolizes the parental sacrifice for the sake of the future chick, the same way as universal symbols, where the duck is a symbol of family happiness, and fertility. Thus, the importance of Aitmatov's usage of myth in the literary work, with the help of which he introduces other cultures and nations to his folk and vice versa, is obvious due to the research paper done. The reason is that it’s exactly the most distinctive feature of his writing style.

Nationwide values and their development in modern conditions
Статья научная
The article deals with the formation of national values in the context of globalization and in these circumstances, human values remain the major connecting element between people and States. It is the system of values is becoming a relevant today, since they define the behavior of human activities and are a source of activity of the subject of social development. The solution to the problem of national values is associated with a number of fundamental issues. In modern society, the upbringing of young people requires personal characteristics drill through forming, ensure the development of value orientations. The value is interpreted as the significance of objects and phenomena, satisfying the need of vital activity of the subjects. The main problem of the choice of values is to find nearly evaporated; and an acceptable combination values of all, not the deification of one of them. The main value of modern youth lifestyle characteristics that are considered when generating the value orientations, fixed: failure or lack of sustainable values; openness to experimentation, innovation and change; the adoption of a diversity of positions and its approval; separation as away of getting used to changing social situations; focus on the present rather than the future and the past; the transformation from an external to an internal verification of its existence, which is reflected in the first of all on oneself and the smallest on the support of the State; the propensity to enter into informal associations and societies with a multi-polar orientation; determination to mobility geographical, social and cultural. This, in modern conditions of diversity of values, development of national values issue requires a more complete study, both theoretical and practical levels.

New approach in teaching English language in the globalization era
Статья научная
English language is identified as one of the most spread languages for the worldwide communication. The intensive globalization of the world in the last decades requires international communication within the wider range of nations and cultures. It is important to recognize the continuous shift of the role of the English language from a second language into the global nature of the English language, in the context of worldwide communication, stressing the fact, that English as a foreign language has become international language. Within the concept of English as a language used for international and intercultural communication, it is consequently important to consider the inseparable role of culture in a language as the cause of the shift from the cultural aspect in English as a second language into the intercultural aspects in English as an international language including consideration of its possible impact on teaching English as an international language.

New book format of the XXI century - electronic textbooks
Статья научная
The rapid informatization process of the education system has created both the opportunities and the need for the use of e-books in education. E-books allow students to actively participate in the learning process, to personalize their learning, to gain new knowledge and to evaluate their own abilities. The e-textbook also enriches traditional forms of learning, encompassing a large amount of teaching and learning materials and stimulating the development of new teaching methods. In our opinion, it is time to switch to electronic and interactive formats in the development of electronic aids and textbooks in universities. One of the leading directions in the use of information and communication technologies today is the effective use of computers in educational activities. The main issue in implementing this activity is the selection of e-learning resources that will improve the quality of education.

New method of using mobile robots for implementing warehouse operations
Статья научная
The new patented method of movements of packaged cargoes at the warehouse is proposed in this article. The proposed method of loading is superior in economic efficiency, reliability, cheapness, simplicity of construction and use, to all other methods of loading implemented by robots. The method allows the mobile robot to load a cargo which is three times as heavy as this mobile robot, wherein almost no electrical energy is consumed during loading. In implementing the method, two mobile robots are used, each of which contains a mobile platform, an omnidirectional mobile wheel-type mechanism and a transport suspension with independent suspension for each wheel. Actually, mobile robots help each other to load cargo on the first mobile robot, through robot cooperation. Loading of the container with the load on the first mobile robot is carried out by actuating a two-arm lever, which is carried out through the impact of the bottom of the mobile platform of the second mobile robot on the longer arm of the two-arm lever by lowering the mobile platform of the second mobile robot due to the operation of the transport suspension of the mobile platform of the second mobile robot. For example, if the length of the longer arm of the two-arm lever is three times longer than the shorter arm of the two-arm lever then the second mobile robot of weight 50 kg is capable of loading a container with a load of weight 150 kg on the first mobile robot.

New method of using mobile robots for moving cargo in warehouse
Статья научная
The new patented method for moving cargo in warehouse is proposed in this article. According to the new method, movement of cargo from the storage area to another warehouse area is carried out by throwing the cargo by the first mobile robot and catching the thrown cargo on fly by the second mobile robot. The parameters of the calculated trajectory of movement, in the free flight phase, of the center of mass of the cargo to be thrown are calculated by numerical methods for solving the Cauchy problem for a system of ordinary differential equations, and by the shooting method for boundary value problems of a system of ordinary differential equations. The first mobile robot throws the cargo at the specified angle to the horizon with the specified initial velocity, at the specified moment of time. In order to catch the thrown cargo on fly by the second mobile robot, the parallel algorithm A1-A2 for catching a thrown cargo on fly by the second mobile robot was created. The method allows the first mobile robot to throw cargoes for large distances, and the created algorithms allow the second mobile robot to catch reliably the thrown cargoes on fly. The proposed method for moving cargo is superior in economic efficiency and reliability to the other methods for moving cargo by implementing tossing of inventory items by robots.
