Modular Green Roofs for the Sustainability of the Built Environment: The Installation Process

The research object is the installation process of modular green roofs with planters placed on the concrete roof’s surface. These roofs effectively reduce rainfall disposal, prolong the lifespan of the roof coating, and enhance urban aesthetic and recreational spaces. Green roofs reduce houses’ gas emissions and increase green spaces in densely built areas. The spatial–technological model was developed for the proposed modular green roof based on network planning, scheduling theory, and graph theory. The sequence and composition of technological processes and operations were established for the installation process. The functional model of installing a modular green roof has been developed. The model makes it possible to optimise the principles of saving labour contribution (working hours) and time.

Investigation of the nature of the process of delivering a batch of containers from the rear terminal to the port

Objective: Assessment of the need to study the process of delivering a batch of containers from the rear terminal to the port to ensure uninterrupted communication between the rear terminal and the seaport and delivery a batch of containers exactly on time. As a primary task, the problem of analyzing the factors affecting the nature of the delivery process is solved. Methods: The methods of the theory of probability and mathematical statistics were applied in terms of determining the factors that affect the nature of the delivery process. The method of constructing process models was used to create a technological model for the delivery of containers by a block train to the port. Results: A technological model of container delivery by block train is presented. Diagrams were built showing the share of the main deviations from the schedule of container trains by types of operations for traffic, traction, corporate transport services. The main factors influencing the duration of individual operations with container block trains en route and the increase in the delivery time for a batch of containers from rear terminals to the seaport as a whole are identified. The random nature of the duration of the delivery of containers by block trains following the schedule has been established. Practical importance: The need to improve the methodology for choosing a method for delivering containers from the rear terminal to the port using simulation based on the identified factors influencing individual elements of the technological model of container delivery by a block train, deviations from the delivery time of containers, scheduled running of block trains is shown.

Mitigation of CH4 emissions in sanitary landfills: An efficient technological arrangement to reduce Greenhouse gas emission.

Problems related to the solid waste have been shown a relevant subject, by contributing to global warming and climate change. The MSW is one of the main sources of Greenhouse Gases (GHG) emissions, especially the methane gas (CH4). Towards this concern, the general objective of this research is to estimate CH4 emissions produced at the Dom Antonio Barbosa II Sanitary Landfill, situated in the City of Campo Grande, state of MS. Its aim, specifically, is to verify the gravimetric composition of these residues, as well as measure the amount of the MSW already existing and also the volume placed in the mentioned sanitary landfill. The CH4 emissions were estimated in an accumulated total of 2,364,556.28 tCO2eq. It was obtained a total reduction of 1,479,693.87 tCO2eq by methane burning, transforming it into CO2, thus it was possible mitigating the emissions of 62.65% of CH4 generated in DAB II landfill. It is expected that the results from this research contribute to the attenuation of the problems related to the MSW impact on the environment, as well as reflect on the effectiveness of the current adopted technological model.

Biographical method for analyzing the results of the application of the technological model of accompanying adolescents registered in juvenile affairs departments

In the introduction, the problem of the competence of the inspector for juvenile affairs when conducting preventive measures with registered adolescents is updated. One of the options for organizing effective preventive measures based on the Technological model of pedagogical support for registered adolescents is proposed. The article describes an unconventional method used by the PD inspector in working with a teenager, the method of prevention "express smartphone control". The purpose of this article is to describe examples of the implementation of a Technological model of pedagogical support for adolescents registered in juvenile affairs departments, which led to a successful change in value attitudes in their worldview. The consequence of the change was the moral choice when the teenager realized himself in society five, ten, fifteen years after the preventive work carried out according to the developed model. In the main part of the article, through the biographical method of research, specific examples are presented that were the result of the use of a Technological model of accompanying adolescents who are registered in juvenile affairs departments. The conclusion of the article contains a generalizing conclusion based on the results of the application of the Technological Model of pedagogical support for adolescents registered in juvenile affairs departments.

EXPERIMENTAL TEST OF EFFICIENCY OF TECHNOLOGY OF TRAINING AND PROBLEM SOLVING IN MEDICAL AND BIOLOGICAL PHYSICS

The article presents the results of research on the introduction of the technological model of professionally oriented tasks in medical and biological physics in the educational process of higher medical institutions (2015 – 2020).The effectiveness of the developed technology for solving professionally oriented problems and tasks, which are based on the method of scientific knowledge, was tested by empirical (assessment of academic achievement, questionnaires, surveys, observations and more) and theoretical (induction, deduction, systems approach, modelling and more) methods of research. The effectiveness of the technological model in the educational process was confirmed by the educational research and the elements of scientific research of students. During the pedagogical experiment were detected problems and contradictions in the process of professional training of future doctors, were described criteria for assessing the academic achievements of students in the discipline of medical and biological physics, including problem solving. The observational experiment showed the insufficiency of the level of formation of natural science and professional competence of students. Control and formative stage of the experiment to assess the effectiveness of the proposed technological content-structural model of solving problems in medical and biological physics, showed the effectiveness of the impact of technology of solving problems in medical and biological physics on the level of positive motivation, level of knowledge, level of educational research and scientific research of students.During the search experiment, technology of solving the tasks, which was confirmed by updated educational and methodical support, was developed. An expert assessment of the effectiveness of the educational process, solving tasks of different levels, levels of skills, and expediency of introduction of educational and methodical support was conducted. The analysis of the results of pedagogical experiment showed the expediency of introduction of developed technology of solving the tasks and training methodical model of support in the educational process. By means of experiment was proved the effectiveness and efficiency of the model of training a specialist in the medical field, in which the leading role belongs to the technological approach to the formation of professional competencies by means of tasks in medical physics, aimed at implementing educational and research activities of students.

ECONOMIC AND MATHEMATICAL MODEL OF CONTAINER BLOCK-TRAINS

The article is devoted to the study of the operation of the container terminal of the Tashkent-Commodity station during the turnover of the container block-train. An organizational and technological model of the container turnover in the form of a network graph is considered, and the technological capacity of the terminal is calculated by modeling operations with containers in the form of a step-by-step algorithm. The resulting methodology makes it possible to predict the duration of the turnover of a block-train and is a kind of imitation of the Uzbek railway network from the point of view of launching a container block-train.Keywords: cargo transportation, admission,delivery, loading, unloading, container, terminal, block-train, algorithm
