I.; Suleimenov, T. B. This paper shows the first knowledge of operation of the turbo-roundabout in the Czech Republic. It shows the main characteristics of this new type of roundabout and wants to compare the differences between turbo-roundabouts in the Czech Republic and in the Netherlands as a mother-land of turbo-roundabouts. The article provides the reader with all known types of turbo-roundabouts, designs, used traffic signs and markings, and comparison of the capacity. The main goal is to emphasize mistakes in the Czech Republic and to show the correct solution for planning turbo-roundabouts to get safety intersection with enough capacity. Analysis shows that there are formed fairly large plugs at following vehicles in both directions at peak periods. Therefore, the authors of this paper proposed a scheme of multilevel road interchange, eliminating conflict points that increase capacity of interchange and ensure the safety of pedestrians. 2019-01-01T00:00:00Z http://repository.enu.kz/handle/enu/1251 Quality assurance and food safety an important State task Bayhozhaeva, B.U.; Abenova, А.А. This article discusses the issues of food quality and safety. The purpose of the study is to analyze the study of state policy in the field of quality and food safety. Improving the quality of products in modern conditions is one of the key economic and political tasks. Therefore, a set of measures such as standardization, state control over its quality, organization of product testing and confirmation of conformity are aimed at its solution. Quality assurance and food safety is the task of the development of society and the state, aimed at improving the quality of life. 2019-01-01T00:00:00Z http://repository.enu.kz/handle/enu/1250 Исследование процесса модифицирования титана и его сплавов плазменноэлектролитическим оксидированием Рамазанова, Ж.М.; Замалитдинова, М.Г.; Жангабыл, М.М. Современное развитие космической техники зависит от уровня эффективности используемых материалов. При этом большую роль играет умение модифицировать и внедрять последние достижения науки. Исходя из этого, в статье освещен метод модифицирования титана и его сплавов с использованием плазменного электролитического оксидирования. Полученное оксидное покрытие обладает высокой адгезией к подложке, износостойкостью и высокой микротвердостью. Ведение процесса в импульсном режиме ПЭО позволяет получить увеличение износостойкости покрытия в 12 раз, микротвердости в 3.3 раза по сравнению с исходным материалом. 2019-01-01T00:00:00Z http://repository.enu.kz/handle/enu/1249 Experience of using precast concrete joint piles in the construction of a Cargo offloading facility in West Kazakhstan Borgekova, К. The paper presents discussions of the bearing capacities of precast concrete joint piles from construction site of the port of Prorva located on the Northeast Caspian Sea. Precast concrete joint piles with cross-section of 40 cm × 40 cm with the total length of 27.5m were used first time in the West Kazakhstan. The piles bearing capacities were received by computational methods as APILE analysis and Kazakhstani standard method, as well as by pile driving analyzer. The analysis showed that the results obtained by the dynamic method of PDA, APILE analysis and the calculation method according to the Kazakhstan standard are similar. The methods described in the article can be applied to determine the bearing capacity of piles and to analyze the interaction of driven piles with problematic soil ground in West Kazakhstan. Considering the calculations performed, APILE analysis can be recommended for use in the design and the dynamic PDA method for testing piles directly on construction field conditions. 2019-01-01T00:00:00Z
