Role of educational projects in the activities of a modern high-technology company DOI: 10.22184/1993-8578.2020.13.7-8.414.418
MAPPER LLC was founded as a subsidiary of the Dutch company MapperLithography. In 2012, 10 process engineers were hired, graduates of Russian universities, who spent 6 months in Holland to learn how to work with high-tech equipment and acquire skills in developing technological processes for the production of MEMS elements. Some of the employees had many years of experience in Europe and America even before their employment at MAPPER LLC. The production of MAPPER LLC was launched in 2014. Since then, the MEMS foundry has been continuously operating and supplying products to its customers. Simultaneously with production activities, the company is intensively developing internship programs and accepting students of technical schools and universities for practical training. Today we present an interview with Rod Irina Andreevna, Manufacturing Director of MAPPER LLC, dedicated to the discussion of the role of the educational programs in the high-tech company's activities, as well as results of the internship implementation.

Structure of the bacillus cereus sporules exosporium DOI: 10.22184/1993-8578.2020.13.7-8.426.432
In the environment B. cereus bacilli are adapted to the saprophytic lifestyle. Under certain conditions, they can become pathogens for humans and animals. The interest in B. cereus bacilli is due to the fact that they cause diseases of the gastrointestinal tract (GIT), and can also cause septicemia, endocarditis, pneumonia, meningitis, etc. An important stage in the life cycle of B. cereus is sporulation. B. cereus sporules have specific structures that are absent in vegetative cells, and are responsible for such sporule properties as thermal stability, resistance to various damaging factors, adhesion to biotic and abiotic surfaces. The data on the fine structure of the B. cerеus exosporium were obtained using transmission electron microscopy and computer image analysis.

Investigation of surface hardening effect on the local mechanical properties of the cutting tools working edge DOI: 10.22184/1993-8578.2020.13.7-8.434.441
In this work the mechanical properties of the punching die cutting edge were investigated by instrumental indentation. The near-surface layer of punching dies is modified in the process of mechanical action with a milling tool and local heating by a laser. Profiles of the hardness on depth have been constructed using the method of automated mapping. It was found that the processing of the tip by local laser heating leads to an increase in the hardness of the alloy by a factor of 1.5 in the region of about 40 μm.

Investigation of the side walls roughness effect of the Si3N4 lightguide layer of different thickness on optical losses in an integral waveguide formed on a quartz substrate DOI: 10.22184/1993-8578.2020.13.7-8.450.457
This article presents results of the influence of the side walls roughness of the 100 nm and 200 nm silicon nitride. Calculation of the main parameters of the side walls roughness of the lightguide layer, which have the greatest effect on the optical loss in the waveguide, carried out by finite difference time domain method (FDTD), is presented. Based on this calculation, the optimal thickness of the lightguide layer of nitride was established, allowing the light flow to be retained. Calculation of the model was based on the data obtained during the study of SEM images of manufactured waveguide structures. The results of these calculations are consistent with the data obtained using optical frequency domain reflectometry (OFDR) in the optical backscatter reflectometer (OBR) of manufactured waveguides with a thickness of silicon nitride 200 nm and width of 3 µm and 8 µm.
