Abstract

The issue of waste management in terms of environmental protection is one of the important problems facing humanity, especially in the large agglomeration areas, and in the rural area, the interests are more limited.

The present paper presents theoretical aspects regarding the implementation of an integrated waste management system in the rural area.

Abstract

The present paper makes an incursion into the new and complex models of communication that can be found in literature, trying to identify their graphic decoding and their applicability in an industrial enterprise. The authors identified real examples for each model under investigation, so the purpose of the paper is to emphasize the importance of communication and the applicability of the new methods of communication in engineering.

Abstract

Drought is a naturally recurring phenomenon of the climate system that affects virtually all regions of the world. During the past decades extreme droughts with extensive negative effects on ecosystems became evident also in the Danube region. At the moment regional capacity to monitor drought is still very diverse and not synchronised among different countries. In this is paper, we present a recently developed drought monitoring tool – the Drought User Service (DUS) for the Danube region using remote-sensing products which aims at offering a more accurate and in near-real-time monitoring via different drought indices. The DUS was created as the monitoring tool of the risk-based paradigm, which seeks to give information in near real-time about the location and severity of droughts throughout the Danube region. Satellite remote sensing products meet the requirements for operational monitoring because they are able to offer continuous and consistent measurements of variables, which can be used to assess the severity, spatial extent and impacts of drought. In the DUS three different variables – vegetation, soil moisture and precipitation – are monitored with earth observation products. The condition of vegetation and soil moisture is tracked with two simple indicators computed as long-term anomalies of the NDVI and SWI products made available through EU’s Copernicus Global Land Service. The importance of DUS and of the developed methods for faster detection of drought onset as useful foundation for establishing a better pro-active drought management in order to mitigate the negative effects of drought in the region is discussed.

Abstract

Nowadays, the air pollution has become a major environmental problem due to rapid increase of industrialization and anthropogenic activities which led to climate change. Air pollution is considered as a harmful agent for human health. Different classes of gaseous pollutants (SOx, NOx) are continuously released in air and perceived/recognized as pollutants. Among the biological models, plants could give us information related with pollution range in a monitored area, analyzing injuries caused on the leaves surfaces. The aim of this study was to identify and select certain species of plants for using them in experimental biomonitoring studies. An experimental fumigation system with a closed fumigation glasshouses maintained under defined conditions with environmental control and pollutant delivery was used to study the effects of air pollution on plants species. The relative degrees of injury as a response of plants to pollutants fumigation were assessed. Considering the sensitiveness degree to pollutants, the indigenous tobacco Nicotiana rustica proved to be the most sensitive followed by cultivated tobacco Nicotiana tabacum and least sensitive Petunia hibrida. Future researches will focus on field biomonitoring.
