In this paper some comparative studies referring to physical and calorific properties of pellets obtained from grape biomass are investigated. The type of grape biomass that is investigated is mainly the pomace, respectively skins and seeds of grapes. Results are firstly specified to the granulometry of milled pomace, and after that to the properties of pellets. Good bulk densities are resulted for grape seed. A higher calorific value of 24.1 MJ/kg is obtained, better those wooden pellets, because this biomass contained some sugars besides of pomace waste. The main conclusion of the paper is that grape pomace pellets have good properties and there are within the limits of the European standards (EN 14961-2). [ABSTRACT FROM AUTHOR]

There are two major aspects treated in this paper. The first concerns the management of potato crop for minimizing the impact to environment and people. Organic potato and its technology are the key words for such management. The second aspect addresses the post-harvest management of organic potato obtained in a friendly environment system, aiming the preservation of their initially quality properties. For this purpose a method for testing using a digital potato is presented. The digital potato is a high tech measurement device, very useful for testing the impact between mechanized system and soil as well as the impacts between potatoes and harmful surfaces from the handling chain. The results obtained with this device are important in the harvest and post-harvest potato management for obtaining quality potato for people consumption. [ABSTRACT FROM AUTHOR]

Atmospheric pollution has often serious consequences to both man and environment, occurring under various forms: home dirt, affected plant growth, diminished quality of agricultural products, reduced visibility, unpleasant smells, and most importantly impaired health. As an unanimous conclusion, all completed research highlights the effects of atmospheric pollution as being a series of consequences on the climate, like: the greenhouse effect determined by the increase of carbon dioxide, cooling generated by an increase of particle concentration in the air, and modifications of the ozone layer. Further, disturbances of the cycles of carbon, oxygen, sulphur may occur, the latter being already well-observable by the increasingly acid rains. These immediate effects are completed by other indirect categories of damage and expenditure due to atmospheric pollution, like replacement and protection of precision apparatus, new sanitary measures in food industry, medical costs, the cost of work time lost due to working incapacity of individuals suffering from consequences of atmospheric pollution. The paper brings an analysis of future technologies and possibilities of diminishing polluting emissions of heat engines. [ABSTRACT FROM AUTHOR]

The paper analyses transport activity from the viewpoint of particularly hazardous substances (petroleum products, chlorine, inflammable products), which may lead to accidents with consequences like material damage, injuries and environment pollution and degradation. The increasing number of accidents has made the factors responsible for environmental health to rethink risk assessment generated by transport activity. It was recognized as a need based options to choose routes, depending on the type and nature of land use around routes. The method consists of a systematic assessment of factors that are influencing transport performance, team and general staff responsible of the transport, and identify situations that may cause road events. It includes identifying the particular error affected the systems interface and the relative order based on the possibility of producing errors or the severity of consequences. The results are qualitative and quantitative and include a systematic listing of scenarios encountered during normal conditions of carriage or emergency conditions. [ABSTRACT FROM AUTHOR]
