Full textOn the basis of data on hydrological and water quality parameters from 28 measure points inthe river basins of Velika Morava, Južna Morava and Zapadna Morava, during ten yearsperiod from 2000. to 2009., this work analyzes spatial and temporal dispersal of pollutantsalong the observed watercourses, as well as the effect of known sources of pollution to thewater quality. In order to estimate the possibility for predicting of some water qualityparameters (concentration of dissolved oxygen, concentration of suspended matters,concentration of o-phosphates, COD and BOD5) values, based on value of flow and timecomponent (month of the year in which the measurement was performed), for 7 measurepoints there are defined statistical regression models.

Full textPGP microorganisms (Plant Growth Promoting) have been the subject of many research projects, whose main goal is to find appropriate methods of their use in agriculture, horticulture, forestry and environmental protection. The aim of this study is the isolation and characterization of microorganisms with PGP characteristics from the rhizosphere of perennial ryegrass, testing their ability to survive after entering the soil, and monitoring the impact of their application on yield parameters and microbial activity in the rhizosphere of plants. Characterization of Pseudomonas, Bacillus and Streptomyces included determination of the physiological, biochemical and PGP characteristics. Impact of the introduction of selected isolates and fungi Trichoderma asperellum on quantity and microbial activity in the rhizosphere of ryegrass was determined by using the standard method of selective media; dehydrogenase activity by the spectrophotometric method. The effects of the implementation of isolates on germination, seedling length sprouts seeds of perennial ryegrass were studied under laboratory conditions. During the year, three cuttings were taken. At each of the three cuttings, length of stem and roots of plants (cm) and yields of fresh and dry matter of the plant (t / ha) were measured.Based on morphological, physiological and biochemical characteristics and PGP characteristics observed in the isolates, and based on the results of many previous studies, it can be concluded that (1) P1 and P9 isolates belong to the species Pseudomonas putida, (2)Pseudomonas fluorescens P12 isolate, isolates of B1, B3, B6, belong to the species Bacillus subtilis, and (3) A1, A2 and A3 isolates belong to the ordo Streptomyces. The quantity of systematic and physiological groups of microorganisms and enzymatic activity in the rhizosphere of ryegrass depended on the applied inoculants. Application of Pseudomonas sp. P12 had positive effects on increasing the total number of microorganisms, fungi, aminoheterotrophs and actinomycetes. Isolate Bacillus sp. B1 affected the increase of the total number of micro-organisms in the fungi and Azotobacter. Application of Streptomyces sp. isolates A3 led to an increase in the number of actinomycetes and oligonitrophyls, while the application of Trichoderma asperellum had positive impact on increasing the number aminoheterotrophs and Azotobacter. Application of Pseudomonas sp. P12 and Streptomyces sp. A3 had the greatest effect on dehydrogenase activity. Inoculation had a positive effect on germination, fresh and dry weight of plant, height and rootlength of plants. Introduction of fungus Trichoderma asperellum and Streptomyces sp. A3 isolate acted positively on germination, length of seedling of germs. On average, the best effects on the yield of fresh and dry matter, the height of the stem of the plant and the length of the root were attained by the application of Pseudomonas sp.P12 and Bacillus sp. B1 isolates. Microorganisms have not yet found significant practical use in the production of forage grasses, even though more qualitative yield has been sought in livestock production. The results of this study demonstrate that positive results in the production of perennial ryegrass can be achieved by the use of microorganisms. Therefore, it is very important to carry out further studies of the relationship between applied microorganisms and ryegrass under field conditions in order to optimize the method and time of application of inoculants.

Full textThe master`s degree dissertation for the amount of work is 79 pages, 42 figures, 33 tables, and contains 10 literature. The object of the work is the set of carbon fiber composite panels of wing. The main goal of this dissertation is the choose optimal configuration of carbon fiber composite panel of wing. Relevance: Parts of composite materials have complex methods of analysis. At the same time, a large number of parts of modern aircraft structure make of composite materials and it is important to select optimal configuration of part, which made of composite materials. The relevance is to solve this problem using the analytical method in Microsoft Excel. The carbon fiber panels are analyzed using the Microsoft Excel. As a result of this work, it was calculated stiffness properties and critical load for a large number of panels and compared this results. Also was performed strength analysis of composite panel.

Full textThe given master's dissertation on volume of work is 54 pages, 23 illustrations, 10 table and contains 6 literary sources. The object of the study is a tensile joint bracket, namely the design, materials used, methods and technologies for the production of such brackets. The purpose of this thesis is to study the effect of geometric parameters of the flange of the channel bracket on the value of the destructive force and the nature of its destruction under static load. As a result of the carried out work two variants of an arm on the form of a channel with various geometrical parameters of flanges were considered. During the calculations, the software package NASTRAN - PATRAN was used to create a 3D model of the bracket.

The thesis is dedicated to the problem of formation of self-educational competence of future civil-engineers in the process of professional education. The thesis outlines the present state of theory and practice of formation of self-educational competence, provides scientific substantiation of organizational and pedagogical conditions and develops a structural and functional model of self-educational competence of future civil-engineers in the process of professional education. Effectiveness of the experimental model and improved methods of forming of future civil-engineers’ self-competence in the process of professional education have been proved. The thesis clarifies the essence and meaning of the notion “self-educational competence of future civil-engineers”, defines its component structure. Criteria, indicators and levels of the studied phenomenon have been concretized.
