چکیده
The results of an analytical-experimental study related to the actual task substantiating comprehensive measures for occupational safety miners in deep coal mines on factors mine air quality based hydrodynamic conditioning processes, which is especially important development autonomous and energy-saving means ensuring miners' standards, are presented. Purpose. goal substantiate analytically main thermodynamic characteristics process hydraulic functional modules conditioners with variable indicators rational capacities that satisfy specific conditions workplaces mines. Methodology. general research methodology a systematic approach analysis include complex analytical mixture water droplets substantiation mathematical model working volume conditioner, experimental laboratory industrial data by methods statistics, as well generalization regarding determination regularities air. results. enthalpy humidity have been determined energy state active component body flow droplets; diagrams assessment essence change thermodynamics conditioner obtained, characteristic relative during its cooling pressure temperature multi-chamber ejector conditioner. Scientific novelty. For first time, thermopotential droplet before after conditioning, changes enthalpy, analytically. practical significance presented that, basis characteristics, it becomes possible calculate necessary initial temperatures (in range 1.0°C-20°C) supplied (for limits 30-50°C), technical condition module local area mine.

Effects of Feeding on Air Quality Measures
Livestock production causes unavoidable losses to the environment, and the concerns related to aerial emissions from livestock production is ever increasing. Losses to the atmosphere occur during respiration and from fresh and stored feces and urine. These losses may be an environmental burden as contributors to global climate change (CO2, CH4), regional particulate or acid deposition concerns ...
متن کاملLegal and Economic Justification for Software Protection
This article discusses legal and economic rationale in regards to open source software protection. Software programs are, under TRIPS1, protected by copyright (reference is made to the Berne Convention2). The issue with this protection is that, due to the dichotomy idea/expression that is typical for copyright protection, reverse engineering of software is not excluded, and copyright is hence f...
