Abstract. According to the research the species of lichens such as Parmelia sulcata, Parmeliopsis ambigua, Phiscia stellaris, Xanthoria parietina are founded on example of small town. Values of clear air index correlated with the average content of sulphur dioxide in the air. These measurement points correspond to residential areas and regions of the objects of food industry. Two zones zero projective coverage are selected. These most polluted zones corresponded to the location of the metallurgical industry and heat electropower station. The roof production and abrasive industry do not show a significant increase in the concentration of sulfur dioxide in the contiguous territory. By method lichen indication on example of small city two zones lichen deserts (sulfur dioxide concentration greater than 0.3 mg/m 3 ) and one area of critical pollution (sulfur dioxide concentration of 0.1 -0.3 mg/m 3 ) were founded. The largest area of air pollution allegedly linked to the activities of plants. Thus metallurgical industry and heat electropower station can be called major air pollutants in small towns.
Abstract. This paper describes the psychological and pedagogical (methodological, motivating, organizational, and content-related) conditions for developing the students' ability to self-regulate, within the framework applied to the mathematics education designed for students at the technical university. The paper gives the results of the experiment indicating the efficacy of these conditions. Groups of students studying at Tomsk Polytechnic University participated in the educational experiment. Tests, observations, questionnaires, techniques of mathematical statistics were used for assessment. The experiment makes it possible to conclude that the self-regulated learning of students on the basis of the Modular Object-Oriented Dynamic Learning Environment 'Moodle' together with the project-related activities, performed by students in the existing production environments, leads to a higher level of the students' ability to selfmanagement.
The publication is devoted to the analysis and justification
of questions of teaching one of the most important sections
of the course "Descriptive geometry" "Geometrical transformations".
On the basis of critical analysis suggestions are made for improvement
of a presentation technique of this section in the classroom
and in academic literature, as well as for extension of application
of geometrical transformations for the solution of position and
metric tasks, surfaces modelling, and also for design of complex
engineering forms that meets certain preassigned conditions.It is
offered to make a number of considerable amendments to the terms
and definitions used in the existing courses of descriptive geometry.
Some conclusions are made, and the appropriate proposals on
feasibility of coordination of movementtransformationteachingin
the courses of analytical and descriptive geometry are made. It will
provide interdisciplinary communications and allow students to be
convinced in usefulness and expediency of a combination of analytical
and graphic ways of geometric tasks solution. Implementation
of these suggestions contained in the article will contribute to a real
transformation of engineering and geometrical training and as a
consequence, the quality of training specialists.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
