ABSTRACT
The traditional use of biomass is still the reality in the world. In 2019 the traditional use of biomass represented 6.5% in total final energy consumption and the modern bioenergy was 5.1% in the world. The modern use of biomass involves the use of advanced and efficient technological processes such as liquid biofuels, production of briquettes and pellets, cogeneration from sustainably sourced biomass and the traditional use of biomass involves inefficient processes of biomass transformation as burning with low technology and use of non-sustainable biomass. In Brazil, the use of firewood as residential fuel has been increasing since 2018 and is currently the second most used source in the residential sector. This is due to the change in the cooking gas price policy that took place in 2017, increasing the price of this fuel, and this combined with the covid pandemic made many families in vulnerable economic situations replace cooking gas with firewood and others kind of the waste and materials. The burning of firewood and other materials in improvised stoves, inefficient with low technology, exposes these families, mostly women and children, the smoke, causing various types of diseases and domestic accidents. In addition, the increase in the use of firewood as fuel causes regression to the fulfilment of the Sustainable Development Goals-SDGs, in particular to goal 7 that calls for “affordable, reliable, sustainable and modern energy for all” by 2030. This paper aims to present is compiling data and technical information about the use of the forest residues consumption by households in large urban centres in Brazil. © 2022, ETA-Florence Renewable Energies., All rights reserved.
ABSTRACT
The article considers the approach to the use of lifting and assembly technological module in installing structural blocks of the building. The urgency of this work is the need to develop methods and means of installation and dismantling of long-span buildings, due to the need to build premises (industrial hangars, concert venues, Covid-hospitals, etc.). Modern approaches to the installation of structural blocks of coatings are analyzed. Improvement of constructive decisions of basic units of a covering and directly their supports is offered. Given that the construction of buildings mainly depends on the level of mechanization on the construction site, the main attention is paid to the improvement of existing mechanized technological means. Based on the offered improvements in a design of a covering and its support use of the mechanized technological module for the realization of raising of the block of a covering to a design mark with the simultaneous growth of columns is offered. In the course of comparison of the offered technology of installation of a covering with the basic crane variant, the degree of consolidation of a covering and ways of robotization of the mechanized module are proved.
ABSTRACT
The article considers, on the basis of application of modern information analytical systems, the sequential stages of analysis and evaluation of indices of resource support of medical organizations and technological process of medical care provision. The results of the study permit to discover particular patterns of the course of disease in different gender and age groups,in terms of clinical manifestations and results of instrumental and diagnostic tests. The dependence of results and outcomes of treatment on set and quality of resources of medical organizations is established. The prognostic indices of functioning of medical organization under various alternatives of patients' flows organization as associated with hospitalization level.
