The article considers the change in the number of days with ice-frost deposits on the territory of Belarus and some features of their formation during the period from 1975 to 2015 for 47 stations. The analysis of the spatiotemporal variability of the number of days with ice-frost deposits was done, ...

Epiphytic microorganisms of grain are indicators on which freshness and a period of storage of grain is estimated. Presence of Aspergillus on wheat of a harvest of 2014 and barley of 2015 demonstrates infringement of parameters of grain storage – the increased humidity. Lack of bacteria of the sort ...

The article analyses chemical composition of natural waters in the Republic of Belarus. It demonstrates a possibility to apply iron complexes with humic substances of worked out ion-exchange pitches (kationit, anionit and their mixes) to purify natural waters.

The purpose of the work is to identify factors that contribute to a high growth in the number of beavers. This allows substantiating methods to reduce their negative impact on water construction. The paper presents an installation to regulate the number of beavers on reclamation canals. Its efficiency ...

For for the processing of diffusion juice of sugar beet production used the drug "Biopag", which contains polyhexamethyleneguanidine chloride. Dynamics of changes in pH, clarification and the numbers of bacteria and yeast suggests the suppression of fermentation processes making the drug at a concentration ...

In this work, first shown the results of ecological-taxonomic analysis of bryophytes pine stands in mossy pine forests and blueberry Suhodolskaja forestry, which complements the characteristic plant communities of the region. Was 12 species of the class Bryopsida and Marchantiopsida. The most widely ...

The article presents a diagram of a heat ventilation system. The system is designed to supply an air flow inside buildings with the function of heating it with the use of secondary and natural energy resources to minimize energy consumption from external sources of buildings’ heat supply.

The analysis of the dependence of the thermophysical characteristics of buildings on the glazing area and thermal resistances of bearing and translucent structures is presented.

The article reflects prospects and ways to use heat from wastewater. It also outlines main aspects of introducing low-potential heat sources into modern heating systems.
