The inactivation of eggs of helminthes under the action of narrowband ultraviolet radiation of excilamps

The inactivation of eggs of Opisthorchis felineus and Diphyllobothrium latum in the water under the action of UV excilamps at 222 and 282 nm in dependence on the surface dose of radiation was studied. It was observed that the water disinfection from eggs of helminthes was more efficient at 222 nm, than at 282 nm. At the surface dose up to 5 mJ/cm2 of UV radiation at 222 nm up to 85 % of Opisthorchis felineus eggs were inactivated. At the comparable surface dose of UV radiation at 222 nm up to 56 % of Diphyllobothrium latum eggs were inactivated

Multifrequency dial sensing of the atmospheric gaseous constituents using the first and second harmonics of a tunable CO2 laser radiation

The results of field measurements of concentration of some gaseous components of the atmosphere along the paths, in Sofia, Bulgaria, using a gas analyzer based on the use of a CO2 laser radiation frequency-doubled with ZnGeP2 monocrystals are presented. The gas analyzer is a traditional long path absorption meter. Radiation from the tunable CO2 laser of low pressure and from an additional He-Ne laser is directed to a colliminating hundredfold Gregori telescope with a 300 mm diameter of the principal mirror. The dimensions of the mirrors of a retroreflector 500 x 500 mm and a receiving telescope allow one to totally intercept the beam passed through the atmospheric layer under study and back

Adhesion and mechanical properties of PDMS-based materials probed with AFM: A review

This work was supported by Russian Science Foundation project grant 18-19-00645 "Adhesion of polymer-based soft materials: from liquid to solid-.Polydimethylsiloxane (PDMS) is the most widely used silicon-based organic polymer, and is particularly known for its unusual rheological properties. PDMS has found extensive usage in various fields ranging from microfluidics and flexible electronics to cosmetics and food industry. In certain applications, like e.g. dry adhesives or dry transfer of 2D materials, adhesive properties of PDMS play crucial role. In this review we focus on probing the mechanical and adhesive properties of PDMS by means of atomic force microscopy (AFM). Main advantages and limitations of AFM-based measurements in comparison to macroscopic tests are discussed.Russian Science Foundation 18-19-00645; Institute of Solid State Physics, University of Latvia as the Center of Excellence has received funding from the European Union’s Horizon 2020 Framework Programme H2020-WIDESPREAD-01-2016-2017-TeamingPhase2 under grant agreement No. 739508, project CAMART

Communicative Teaching Students English for Successful Participation in International Projects

Рассматривается вопрос о коммуникативном обучении студентов английскому языку. Обосновывается необходимость формирования и развития умений и навыков деловой коммуникации для последующей успешной профессиональной самореализации. Особое внимание уделяется коммуникативному бизнес-ориентированному подходу в обучении с целью подготовки специалистов в рамках межкультурного делового общения.The issues of teaching students English for its application in international business and also of the need for communication in a foreign language in future professional activity as part of intercultural business communication are examined. The relevance of learning English to be ready for successful professional self-realization is substantiated. Particular attention is paid to a communicative business-oriented approach to learning English which is aimed at the training specialists in business communication

Scientific-theoretical background the organization of geobotany employees of the micro enterprises sport and recreation sector

The relevance of the research problem due to the needs of the labor market, terms of developing economy of micro-entrepreneurship in sport and recreation sector and the demands of the subject of labour activity to professional training without discontinuing work. The purpose of the article is to understand the current issues aspects of pedagogical learning situation of a potential employee an experienced professional when using the internal resources of micro-enterprises. A leading approach to the study of this problem is systematically-activity, which allows to represent the process of professional learning in conditions of the micro-enterprise as a system activity of subjects for the development of professional competence of the employee sports and recreation sector. The results of the research showed that the process of training and professional interaction of the micro-enterprise employees to be effective if educational-vocational. interaction of the micro-enterprise employees will be considered as a productive mutual agreed actions of subjects of labour, aimed at solving educational and professional problems in the process of joint labour activity. The article can be useful to researchers of the problem of industrial education in the current socio-economic conditions, from a practical point of view - chiefs of micro-entrepreneurship in sport and recreation sector. © 2016 Andruhina et al
