Reforming of the bachelor‘s chemistry programme in accordance with the international standards of engineering education

The challenges of the regional economy and the high demand of the industry for engineering and technical personnel in chemistry led to the need to reform the bachelor's degree program in chemistry in accordance with the best world practices according to the standards of the World Engineering Initiative. With the purpose of constructing a practiceoriented educational program, the study of the needs of the industry was conducted by interviewing the largest companies employing graduates. The results of the survey were taken as the basis for developing the characteristics of the graduate. The characteristics of the graduate, in turn, are decomposed to the results of the training. The educational program of the baccalaureate "Chemistry" is modernized in accordance with the characteristics of the graduate and the results of the training. As a result of this work, new disciplines were introduced, during the development of which the most sought after results of training are formedВызовы региональной экономики и высокий спрос отрасли на инженерно-технические кадры в химии обусловили необходимость реформирования программы бакалавриата по химии в соответствии с лучшими мировыми практиками по стандартам Всемирной инженерной инициативы. С целью построения практико-ориентированной образовательной программы проведено изучение потребностей индустрии путем опроса крупнейших компаний, трудоустроивших выпускников. Результаты опроса были положены в основу разработки характеристик выпускника. Характеристики выпускника, в свою очередь, декомпозированы до результатов обучения.

Electrical discharges in the atmosphere of Venus

Data received from Venera 11 and 12 experiments involving the electrical activity of the atmosphere of Venus show that the electrical discharges occur in the cloud layer. Their energy is roughly the same as in terrestrial lightning, but with a pulse repetition frequency of the discharges which is much greater

Elastic properties of FeSi

Measurements of the sound velocities in a single crystal of FeSi were performed in the temperature range 4-300 K. Elastic constants $C_{12}$ and $C_{44}$ deviate from a quasiharmonic behavior at high temperature; whereas, $C_{12}$ increases anomalously in the entire range of temperature, indicating a change in the electron structure of this materia

Giant Pulses with Nanosecond Time Resolution detected from the Crab Pulsar at 8.5 and 15.1 GHz

We present a study of shape, spectra and polarization properties of giant pulses (GPs) from the Crab pulsar at the very high frequencies of 8.5 and 15.1 GHz. Studies at 15.1 GHz were performed for the first time. Observations were conducted with the 100-m radio telescope in Effelsberg in Oct-Nov 2007 at the frequencies of 8.5 and 15.1 GHz as part of an extensive campaign of multi-station multi-frequency observations of the Crab pulsar. A selection of the strongest pulses was recorded with a new data acquisition system, based on a fast digital oscilloscope, providing nanosecond time resolution in two polarizations in a bandwidth of about 500 MHz. We analyzed the pulse shapes, polarisation and dynamic spectra of GPs as well as the cross-correlations between their LHC and RHC signals. No events were detected outside main pulse and interpulse windows. GP properties were found to be very different for GPs emitted at longitudes of the main pulse and the interpulse. Cross-correlations of the LHC and RHC signals show regular patterns in the frequency domain for the main pulse, but these are missing for the interpulse GPs. We consider consequences of application of the rotating vector model to explain the apparent smooth variation in the position angle of linear polarization for main pulse GPs. We also introduce a new scenario of GP generation as a direct consequence of the polar cap discharge. We find further evidence for strong nano-shot discharges in the magnetosphere of the Crab pulsar. The repetitive frequency spectrum seen in GPs at the main pulse phase is interpreted as a diffraction pattern of regular structures in the emission region. The interpulse GPs however have a spectrum that resembles that of amplitude modulated noise. Propagation effects may be the cause of the differences.Comment: Astronomy & Astrophysics (accepted

Mössbauer spectroscopy with a high velocity resolution applied for the study of meteoritic iron-bearing minerals

Mössbauer spectroscopy with a high velocity resolution was applied for study of iron-bearing minerals in different meteorites. The possibility of technique to reveal small variations in Mössbauer hyperfine parameters of the 57Fe in the non-equivalent M1 and M2 sites in olivines from Farmington L5 and Tsarev L5 ordinary chondrites and from Omolon and Seymchan pallasites was demonstrated. The necessity of accounting for the Fe and Ni occupation probabilities in the local microenvironments for non-equivalent sites M1, M2 and M3 in schreibersite, an iron nickel phosphide from Sikhote-Alin iron meteorite, in the fit of its Mössbauer spectra was shown. Variations in Mössbauer parameters of metal samples from visually different areas at the saw-cut surface of Chinga iron meteorite fragment with unknown origin were observed; these variations may be related to different metal phase composition and local variations of Ni concentration in the metal phases in these areas. © 2012 Elsevier B.V.

AR/VR technologies in management and education

The potential of some technological innovations for a long period of time remains either not fully explored or underestimated. The article gives a brief description of the AR and VR technologies, shows the possibilities of their use in various sectors and industries of the modern world economy. The paper provides an overview of the positive aspects and competitive advantages that AR and VR technologies can bring to companies engaged in the development and production of devices and instruments that allow using these technologies. This is a growth in sales of products and services, a reduction in operating costs, an increase in customer satisfaction, an improvement in the quality of product, services and service. The study also considers the limitations of using AR and VR technologies in educational environments. According to the authors, there are more industries and areas where AR and VR technologies can be applied.The paper analyses the volume of investments in the field of VR / AR, gives the forecasts of possible improvements of VR and AR devices, leading to creating of wider opportunities for their utilization in industrial, financial and educational spheres. The article presents the most successful examples of the implementation of AR and VR technologies in 2012-2021 in foreign and Russian companies.

Blood fibrinogen concentrations in New Zealand white rabbits during the first year of life

The aim of this study was to examine the reference range of blood plasma fibrinogen, which belongs to the group of moderate acute phase protein in rabbits. The experiment followed the dynamics of blood plasma fibrinogen (Fb) during the first year of life in 12 New Zealand White rabbits, 6 males and 6 females, starting at 1 month of age until the 7th month. It was shown that fibrinogen concentrations increased with the age. There was a statistically significant difference in Fb concentrations in rabbits at 3 (P<0.05), 6 (P<0.01) and 7 months of age (P<0.001) compared to levels obtained at 1 month of age in both genders. At ages of 1, 2 and 3 months, fibrinogen values were higher in male rabbits while in 7-month-old rabbits, plasma fibrinogen levels in females were significantly higher than those in male rabbits (P<0.01)

Petroleum-related hydrocarbons in deep and subsurface sediments from South-Western Barents Sea

Subsurface sediments from a pockmark area in South-Western Barents Sea have been earlier found to contain elevated levels of petroleum-related polycyclic aromatic hydrocarbons. This work describes a comprehensive analysis of various biomarkers, including the highly source-specific hopanes, in a 4.5 m long gravity core from the same area, together with subsurface sediment samples from other areas in the region without pockmarks present (“background samples”). A clear difference between the pockmark gravity core and the background sediment cores was found, both with regard to genesis and the level of transformation of organic matter. A number of indicator parameters, such as methylphenanthrene index (MPI-1), point towards a significantly higher maturity of hydrocarbons in the pockmark core throughout its length as compared to the other sampled locations. Higher contents of microbial hopanoids (hopenes) may indicate the former presence of petroleum. These findings confirm the hypothesis of a natural hydrocarbon source in the deeper strata present in the studied location with pockmarks
