This research aims to produce valid and reliable prior knowledge questions on the concept of cellular respiration online by utilizing Google form media. The questions developed in this study are multiple choice questions with a four-tier test type. The sample in this study were students who took general biology courses at Faculty of Teacher Training and Education (FKIP) of Universitas Sriwijaya. Samples play a role in the evaluation process after prototype I was produced, at one-to-one (n = 13) and small group (n = 23) stages. The instrument used in the data collection process was a walkthrough, question readability questionnaire and questions. The questions given to the sample consisted of multiple choice questions on the grounds of open-ended questions (the development stage) and four-tiered multiple-choice test questions (the small-group evaluation stage). The use of the Goggle form in this study was carried out at the stage of giving open-ended question questions and the evaluation process at the one-to-one and small group stages. The results of this study indicate that the prior knowledge questions that have been developed are categorized as valid with an expert review rating of 80.5% and the reliability of the categorized questions is weak with a value of 0.37. The results of the expert review assessment revealed that the items developed were in accordance with the understanding of the concepts to be measured. Findings from the results of this study can be used as a reference for developing prior knowledge questions with the type of four-tier test to detect students’ understanding before learning is done. Thus the teacher is expected to choose the right learning strategy before the learning process.

Authors: Nursalim R , Agustiani R , Muslimahayati
Published: May 2020

This paper will be presented to explain the velocity profile of viscous fluids at non-stagnation points when the fluid passes through a sliced sphere contains magnet. The design of this study was an experiment using computer simulations based on mathematical models built. Mathematical models and coordinate systems are built based on physical phenomena and are composed of continuity equations and momentum equations. The model was converted to a non-dimensional model and solved by the Keller Box numerical method. Numerical simulations are carried out by varying the incision angle and looking at the fluid velocity profile that occurs. The simulation results show that if magnetic parameter is not included then the velocity will be different at each point, the greater the observation angle the greater the velocity. If magnetic parameter is included then the velocity will tend to be the same. If an observation angle hold on any value then the greater the magnetic parameter the greater the velocity.

Authors: Yastrebinsky R N , Karnauhov A A , Yastrebinskaya A V
Published: May 2020

The paper presents the results of studies of the thermal stability of titanium hydride and titanium hydride containing a borosilicate framework. It is shown that the presence of chemically attached boron atoms on the surface of titanium hydride particles increases the initial dissociation temperature of titanium hydride. The phase composition and imperfection of titanium hydride crystals in the temperature range of 100-700 °C were studied. An increase in the defectiveness of the structure of a titanium hydride crystal during its heat treatment is shown. Mechanisms for modifying the surface of titanium hydride by surface assembly and the creation of a borosilicate framework have been established. It was shown that the ongoing structural-phase transformations in the borosilicate coating activate solid-phase interactions and contribute to the fixation of borosilicate. Based on the data of thermogravimetric analysis, it was shown that the modification of titanium hydride increases its thermal stability by 185 °C, shifting the onset of dehydrogenation processes to the high-temperature region from 463 °C to 649 °C.

Impact of the error of circular control methods on assessing the quality of anti-erosion soil tillage on slope lands
Authors: Vasilyev S A , Vasilyev A M , Fedorova A A , Aleksandrov R I
Published: May 2020

The scientific article considers the impact of the error of circular control methods on assessing the quality of anti-erosion soil tillage on slope lands. The applied control methods are implemented in scientifically based designs of technical control facilities that can provide high measuring accuracy of the parameters, when profiling the soil surface for different slopes of the agricultural landscape of slope lands. It was found that the device error along the measurement path is negligible, since it is theoretically possible to set the scanning angle of 60 or more degrees, while the radial error is restrained, which does not allow setting such limits of angles even when the device arm length is 0.5 m. On the bases of the results of analytical studies, we obtained a graph of changes of the surface width being measured after the passage of the working part, depending on the scanning angle when the mechanism vibrates. The analysis of the graph allows us to conclude that in order to scan the underlying surface in case the working part width of the anti-erosion machine is known or can be predicted within the acceptable error values, it is necessary to change the radius of the scanned circle by changing the arm length. For example, when working part width is less than 0.5 meters, you can use any circle radii. If the width of soil tillage - from 0.5 meters to 1 meter, the circle radius should be more than 0.7 m and the scanning angle should be less than 50 degrees. When the width of the working part of more than 1 meter the circle radius should be about 3 meters that slightly complicates the design of the device since the diameter reaches almost 6 meters.

Authors: Starokon I V
Published: May 2020

The article analyzes the effectiveness of the application when designing offshore engineering analysis systems, which are collectively called CAE. Currently, the production of offshore oil and gas resources, which are extracted using offshore hydraulic structures, is actively developing. These structures are offshore stationary platforms (SMEs) of pile type for various purposes. Offshore platforms are subject to various loads and are in a difficult stress state. The calculation of their real stress state is a difficult task. A solution to this complex problem can be found by building a computer model in a specialized CAE software package. To date, a large number of CAE systems with various functionalities have been developed. In this regard, a technique is needed to evaluate the effectiveness of a specific CAE software package to solve the problem of assessing the stress state of a stationary marine platform. The author offers his own methodology for assessing the effectiveness of CAE packets and gives an example of its practical application.

Published: May 2020

Manipulators with manual control are widely used for moving objects, which is due to the complexity of the process automation and the risk of control errors. The effectiveness of work manipulator operators depends on the number of repetitions of the work cycle by the operator at the training stage and the psychoisiological characteristics of the operator that affect the speed of acquiring control skills. On the example of a hydraulic reloading manipulator, the optimal number of repetitions of working cycles by the operator is experimentally determined, in which the operator is able to provide the minimum time for carrying out the operations of grab, lifting and moving, lowering and placement the cargo.

The use of plasmon resonance spectroscopy to analyze the parameters of thin layers
Authors: Yatsyshen V V
Published: May 2020

The paper presents the results of calculating the angular spectra of ellipsometric parameters and ellipse parameters upon reflection of right-polarized light onto the Kretchman layered system under conditions of excitation of surface plasmons at the boundary of the silver metal layer. It is shown that the studied parameters turn out to be very sensitive when a film of the material under study is placed in a layered system. The conditions are found under which a change in the nature of the polarization of the reflected wave occurs - from the right circular wave of the incident wave to the left elliptical in reflected light. Thus, the use of circular polarization and ellipsometry in plasmon resonance spectroscopy expands the possibilities of this method, in which only the energy reflection coefficient of p-polarized light is studied.

Ways of helium development in Eastern Siberia
Authors: Feodorov A B , Egorov A V , Sviridov L I , Prokaten E V , Bushkina A V
Published: May 2020

The Baikal natural gas deposits are ten times higher than the Orenburg oil and gas condensate field in terms of helium content. The Orenburg field is the raw material base of the Orenburg helium plant, which is part of Gazprom Dobycha Orenburg. Helium is characterized by increased ability to leak out. It is no coincidence that two deposits of Eastern Siberia geographically gravitate towards the deep Baikal fault. Hydrocarbon deposits in the north of the Krasnoyarsk Territory characterized by an increased fracturing system may have interconnections with deep faults. The study of such geological conditions in the development process is promising for increasing the raw material base of helium mining. Helium production technology is based on low-temperature gas condensation. The application of membrane gas separation technology is promising. Separation blocks can be incorporated into the infrastructure of compressor stations. This approach to the deployment of helium production capacities will increase the efficiency of capital investments. Relatively small volumes of productive helium can be transported without reference to pipeline systems. The proximity to the Yenisei and the Northern Sea Route makes the issue of the development of gas condensate production relevant. Placing production wells near the intersection of several fracturing faults is also effective in terms of high inflows. Of particular interest are wells drilled near discontinuous faults. Under these conditions, one can rely on helium inflows through microcrack systems from deep horizons.
Operation analysis of expander-generator unit at a gas distribution station
Authors: Mukolyants A A , Buranov M D , Sotnikova I V , Makhmudov H F
Published: May 2020

The article touches upon the urgent problem of deploying secondary energy resources in the system of transportation and distribution of natural gas. Excessive gas pressure as the main component of secondary energy resources for technological processes is practically not used at gas distribution stations, where throttle devices are deployed. The proposal to utilize excess gas pressure in turboexpander both at gas distribution stations and at compressor stations of gas pipelines without preheating has not yet been widely applied, and therefore the replacement of throttle devices with turboexpander units will be determined by energy and economic efficiency. One of the effective technologies to reduce the consumption of fuel and energy resources is the expander-generator technology. In combination with heat pump units, expander-generator units allow you to create highly efficient energy-generating complexes that can generate electricity without burning fuel. The possibility of generating electricity without burning fuel by expanding high-pressure natural gas at gas distribution stations is being considered. An analytical dependence has been obtained to determine the proportion of electric energy supplied to the electric network based on the expander-generator unit in the gas supply system.

Influence of the chemical composition of steel on the formation of a stone-like fracture and the microstructure of cast steels
Authors: Skryabin M L
Published: May 2020

The article presents the main regularities of the formation of a stone-like fracture of cast steels. The peculiarity of the formation of this defect is the presence of high temperatures and enrichment of the main alloy with small particles and austenitic phases. On the surface of a rock-like fracture, you can often find a matte light gray color, with a metallic sheen. The primary rock-like fracture can be observed after overheating and cooling, that is, before heat treatment. Secondary fracture occurs after metal overheating before hot deformation, such as forging, rolling, and stamping, and also occurs after overheating during heat treatment. The study of patterns of formation of a stone-like fracture in cast steels is one of the most important tasks of modern engineering.

Published: May 2020

The connection between the state of the territorial technosphere and the ecological well-being of man is obvious. Modern research is aimed at studying the effect of pollutants on individual natural systems and do not take into account their complex effects. The assessment is carried out according to individual parameters, not combined into generalizing indicators characterizing the state of the territorial technosphere as a whole and not taking into account the contribution of each. A method for processing measurement information is proposed, which makes it possible to evaluate the contribution of each impact to the final coagulation index. This index characterizes the state of the territorial technosphere taking into account the current aspects and the analyzed criteria and allows, using the method of hierarchy analysis, to determine the weighting coefficients for each aspect. A feature of the proposed method implementation is the lack of subjectivity in the ranking of the analyzed criteria due to the use of not subjective expert assessments, but quantitative values enshrined in regulatory legal acts. The results of such an analysis are important for setting priorities for the implementation of environmental measures and ensuring the ecological well-being of man.

This article is devoted to the problem of improving the quality of engineering education in Russia. The gap in the quality of engineering education and the growing requirements for graduates become increasingly noticeable and is an obstacle to the reforming and upgrading the Russian economy. The success of Soviet engineering schools was mainly associated with two military mega-projects: aerospace and nuclear involved leading technical universities. The transition to a market economy and integration into the global economic system require reforming engineering programs, strengthening the economic training of engineers and restructuring the technical universities. The Russian leading technical universities occupy relatively low ranks in international rankings. The purpose of this article is to help in choosing ways (trends) to improve the quality of Russian engineering education by means of a critical analysis of the leading world technical universities’ experience.

Published: May 2020

This article discusses the approach to determining the maturity level of the organization of secondary vocational education on the example of the Krasnoyarsk College of Radio Electronics and Information Technology. The study is based on a survey of teachers and college staff for different periods of time. The research structure is based on the Voyager Plant Optimization methodology, the questionnaires are designed in accordance with the McKinsey model and adapted to the system of secondary vocational education in Russia. The survey was conducted in two directions: personnel management and increasing efficiency and showed the degradation of the organization’s maturity level under the influence of environmental factors of the organization. The results reflect a prolonged transition process in the college caused by a continuous sequence of organizational changes, such as: transfer to the Krasnoyarsk Territory in 2012, merger with the Krasnoyarsk College of Radio Electronics, Economics and Management in 2015, a constant change of leadership from 2015 to 2019.

The article describes the features of the organization of satellite communication systems in the separated and northern territories of Russia. For such conditions, satellite communications should support traditional voice and broadband Internet access. A promising method for implementing broadband access is to combine the DVB and TCP / IP protocol families without modifying them, taking into account their features. This will allow for the translation of data streams with all the advantages of DVB protocols in the most popular modes at the world level at present: many information sources – many information recipients. The use of the DVB-S2X standard for access to multimedia resources and the Internet requires the adjustment of IP packets for user packets of the UP (User packet) DVB-S2X standard. To support multiple access for different users, it is possible to use TDM time division multiplexing of UP packets. A hardware-software complex for the development and experimental research of methods for broadband access to multimedia resources and the Internet is described. The proposed software architecture provides the user with tools for conducting experimental studies of the studied methods. One of the important advantages of the proposed architecture is the breakdown of functionality into modules, which will allow parallel development of all modules at the same time and simplify the process of creating software.
