Published: December 2020

Abstract
The issues of concretization and expansion of the parametric model “impact - weakening - carrying capacity” application for describing injuries to workers in both mechanical engineering and sports are considered. Based on previously obtained results from other studies, injuries were selected and described by severity (mild, moderate, severe). For quantitative assessment of injuries that often occur both in production and in sports, the article developed and tested a parametric criterion for mechanical damage of an employee or an athlete based on the model “fuzzy impact - fuzzy bearing capacity”. The results obtained can be useful for a comparative analysis of working and sports conditions and substantiation of methods and means of protection against the negative action of mechanical factors.

Published: December 2020

Abstract
Information in the scientific literature is, in the future, the basis for the development of a methodology for normalizing the dose of environmental factors with an assessment of the energy activity of a plant organism. The experience and prospects of using databases for the analysis of natural and artificial factors of the environment in relation to closed systems with an artificial microclimate are discussed. The growing understanding of the ineffectiveness of the empirical approach to the formation of an artificial microclimate makes it necessary to consider the issue from the point of view of dose dependence and biological effect. The purpose of the study is to create an electronic database “Investigation of signs of plant energy activity on the dose of environmental factors”, on which the methodology for standardizing the artificial microclimate in greenhouses will be based.

Published: December 2020

Abstract
Extensive data have been accumulated indicating that for the regions of the Far North, the most effective are opaque greenhouses with enclosing structures of sufficiently high resistance to heat transfer, providing for the cultivation of plants under artificial or joint (semi-opaque greenhouses) lighting. From 1 m of such structures, you can get 140 … 300 kg of vegetables per year. To maintain a certain air temperature in greenhouses, mainly two heating systems are used: water and air. Extensive data have been accumulated indicating that for the regions of the Far North, the most effective are opaque greenhouses with enclosing structures of sufficiently high resistance to heat transfer, providing for the cultivation of plants under artificial or joint (semi-opaque greenhouses) lighting. From 1 m of such facilities, you can get 140 … 300 kg of vegetables per year. When growing plants in cultivation rooms in winter and spring, it is necessary to artificially maintain climatic factors affecting the growth and development of plants. In this regard, the automatic regulation of these factors in accordance with the requirements of agricultural technology is of great importance. To automatically maintain the temperature in greenhouses, a two-position control system is used. Large-scale greenhouse production is currently developing along the path of introducing technologies for intensive cultivation of vegetable crops and the use of automated control systems for technological processes based on micro- and mini-computers. One of the important technological processes is watering and feeding plants with mineral fertilizers. The need to automate this process is associated with the laboriousness of the process of preparing solutions, accurately maintaining a given concentration of substances in them, timely supply and uniform dosing over the entire area of the greenhouse under various disturbances of the external environment.

Published: December 2020

Abstract
In this research, the dynamic crushing behavior of crash boxes made of aluminum reinforced with Glass Fiber Reinforced Polymer (GFRP) with circular cross-section is presented. Energy absorption capacity and damage behavior for different composite wall thickness and fiber ply orientation were investigated. The result shows that adding composite layers to the aluminum column will improve the column’s energy absorption capacity. Nevertheless, the Specific Energy Absorption (SEA) of the aluminum structures generally higher than the hybrid systems. However, the hybrid column has higher crushing resistance than a combination of separate aluminum and composite crash boxes with the same geometry. This shows that interaction between aluminum and composites enhance the crash behavior since a stable and progressive crushing mode were observed, resulting in greater energy absorption. Additional research should be carried out to investigate further.

Published: December 2020

Abstract
Kampung Deret Petogogan program is considered successful in changing the face of housing that was previously shabby, neatly arranged with sturdy houses, and housing facilities. Slums are no longer visible in the settlement. Residents now live in a cleaner, neater, and more comfortable environment than before. The government also plans to make the Kampung Deret Petogogan a model for other slums. For this reason, an evaluation is needed whether the housing built with RISHA (Healthy Simple Instant Home) technology has met the health and comfort aspects, including lighting, humidity, and ventilation of a house. The method used in this is an observational study with a qualitative understanding of architectural phenomena in the field based on theoretical knowledge references. Data collection was carried out through direct observation in the field and interviews with the chairman of the community forum o/Kampung Deret Petogogan. The data obtained is compared with the required criteria related to aspects of lighting, humidity, and ventilation of the dwelling. Field findings show that the design of RISHA in the Kampung Deret Petogogan has not met the health and comfort criteria of a house, as seen from the lack of achievement in design related to lighting, humidity, air circulation, and ventilation. There is a need to adjust the RISHA unit’s design to make it a habitable residence that can be applied to other slums.
