Actual questions of ecological and urban planning zones of the regions for the formation of territorial and industrial complexes (TIC)

Introduction: In the context of accelerated development of production, which is typical for the rapidly developing republics, which include the Republic of Kazakhstan, one of the urgent problems is the creation of favorable living conditions of the population. Materials and Methods: Among a wide range of questions necessary for solution of this problem in the Republic of Kazakhstan the sanitary-hygienic and ecological comfort of living of the population, and also, preservation of the natural environment become of special, in many aspects the priority importance. Results and Discussion: Improvement of research skills of ecological and urban planning specifics of the formation of population systems in the areas of Kazakhstan territorial and industrial complexes and the development of effective planning techniques of functional and spatial organization at the settlement systems is an important area of research. Conclusions: The author’s research is presented in this framework

Computer Simulation of Temperature Profiles for DC Pulse Plasma Jet Modification of Co-based Plasma Detonation Coatings

This paper deals with locating the temperature field in a coated plate heated by a moving heat source. The relevance of this problem lies in the challenge of selecting the optimum exposure modes for modifying irradiation of protective powder coatings deposited by a high-speed plasma jet. Based on a number of ex-perimental studies of the structure and properties of these coatings before and after additional plasma jet irradiation, we concluded that it is necessary to model the distribution of temperature during irradiation in order to justify the choice of irradiation parameters such as the source power density and speed. The val-ues and the distribution of temperature in depth from the surface heated by the source play a crucial role in reducing the particles of strengthening phases from the solid solution and accelerating diffusion pro-cesses between the coating and the substrate. Comparing the experimental data with the calculations of the temperature profile, we can offer the best exposure modes, which do not lead to excessive heating of the coating, but result in changes in the phase composition and the improvement of adhesion of the coating with the substrate by accelerating the diffusion processes between the coating and the substrate.

Generation and characterization of pigment mutants of Chlamydomonas reinhardtii CC-124

The induced mutagenesis method for deriving pigment mutants of a green microalga, Chlamydomonas reinhardtii CC-124 and their pigment composition as well as ability to assess mutability of contaminated aquatic ecosystems were studied. In the present study, 14086 mutants (colonies) were obtained by exposure of the wild strain, C. reinhardtii CC-124, to 1, 2, 3, 5 min of ultraviolet (UV) irradiation. After screening, these mutants (colonies) revealed four pigmented mutants (124y-1, 124p-1, 124y-2 and 124p- 2). Compared to the wild CC-124, these mutants are characterized by a decrease in chlorophyll a & b content and an increase in carotenoids. The lowest decrease in chlorophyll a was three to four folds, while the highest increase in carotenoids was two to four folds. The result of bio-test, using the resulting pigment mutant of C. reinhardtii 124y-1 showed that mutagenic activity was observed significantly in both Tekeli River and Pavlodar Oil Refinery in Kazakhstan; the waste water of the Pavlodar Oil Refinery had high-toxicity while the water of the Tekeli River had medium-toxicity.Keywords: Ultraviolet (UV) mutagenesis, Chlamydomonas reinhardtii, biotesting

Preservıce Teachers’ Opinions on the Use of Technology in Education

Educational technologies have become more important especially in the recent years. The use of technology to facilitate learning has increased over the past decade, but relevant problems in education are still on the agenda. The aim of this study is to determine the opinions of preservice teachers about using technological tools in education. Qualitative method was used in the study. The study was applied to the 32 senior students studying at the classroom teaching department of a university in Kazakhstan. Data were collected with interviews. The interview questions were prepared to get the opinions of preservice teachers studying in the classroom teaching department regarding the use of technology in educational technology, and the questions were applied by giving the final shape by the experts in their fields. According to the results, preservice teachers feel insufficient to use the internet and computer for teaching purposes. However, they stated that they are sufficient in using computers and internet search engines, they can prepare simple materials for teaching purposes and they can not prepare multi-purpose teaching devices. This difference can be overcome with individual research and project assignments that require preservice teachers to use technology for teaching purposes
