Data on the thermochemical plants fed by solid biomass in the north-west area of Italy (Liguria, Lombardy, Piedmont and Aosta Valley) have been organised, analysed and discussed. Moreover, the biomass availability and potential has been evaluated. A total of 28,167 plants have been categorised according to their typology and output: thermo-electric power plants for electricity production, thermal plants for heat production, cogeneration plants for combined heat and electricity production and district heating installations for local heating purposes. In general, separate observations for the different provinces may be drawn. Liguria stands out as the most evident case of under-exploited biomass potential, followed by Aosta Valley, which, however, is rich in hydroelectricity. Lombardy and Piedmont are more virtuous and have several plants in their territory. The construction of new plants and the upgrade of existing ones may bring noteworthy benefits, as well as the use of added value sub-products to foster circular economy approaches.

This work analyses and discusses data on thermochemical plants in Southern Italy that are fed with solid biomass. The analysis takes into account the biomass availability and potential together with the cost-benefit analysis using technology development and economic indicators (LCOE). A total of 63,762 units have been categorised according to the employed technology and produced energy: power plants for electricity production or cogeneration plants for combined heat and electricity production (53 plants) and thermal units for heat production (63,709 units). The eight regions of the area have noteworthy differences. In terms of electricity generated from solid biomass Calabria is by far the largest producer, followed by Apulia. Sicily, Sardinia and Molise provide lower amounts while Abruzzo, Basilicata and Campania generate almost negligible amounts. Regarding thermal production, Campania and Calabria are the largest producers, but Basilicata, Molise and Abruzzo generate the highest amount per capita. The area is far from fully exploiting its biomass potential, and there are also no district heating grids. Bioenergy can be remarkably competitive, provided that capital costs are relatively low and low-cost biomass is available, as it is the case of Italy. New applications and markets for sub-products (i.e., char, ash) would help in lowering the still not competitive economic indicators (LCOE).

In this paper, the impacts of some meteorological parameters on the SO2 concentrations in the City of Obrenovac are presented. The City of Obrenovac is located in the north-west part of Serbia on the banks of the River Sava. The observed source emission, the power plants TENT A and TENT B are situated on the bank of the Sava River in the vicinity of Obrenovac. During the period from January to November 2006, the concentrations of sulfur dioxide in the air at 4 monitoring sites in Obrenovac were measured. It was noticed that the maximal measured daily concentrations of sulfur dioxide ranged from 1 ?g/m3 (16th November, 2006) to 98 ?g/m3 (29th January 2006) and lie under the maximal allowed concentration value according to the Serbian Law on Environmental Protection. The measured sulfur dioxide concentrations mostly showed characteristics usual for a daily acidification sulfur dioxide cycle, excluding the specificities influenced by the measuring site itself. Sulfur dioxide transport was recorded at increased wind speeds, primarily from the southeast direction. Based on the impact of meteorological parameters on the sulfur dioxide concentration, a validation of the monitoring sites was also performed from the aspect of their representivity.

The programme of oral vaccination of wildlife started in 1988 in Slovenia and is based on our and the experiences of other countries. Red foxes are the main reservoir of rabies in Slovenia. When the oral vaccination programme started in whole territory of Slovenia in the year 1995, 1089 (28.75%) of tested animals were detected positive among wild and domestic animals. Four years later only 6 (0.5%) positive cases were detected among 1195 tested animals. The number of positive cases been increased again in 2001 to 135 cases. Between 2002 and 2008 the vaccination was done only in the protection zone, a 30 to 50 km wide belt along the southern border with Croatia because no new rabies cases were found in the north-west region of the country. When rabies was reintroduced in Italy in 2008 the vaccination was carried out again in the whole territory of Slovenia. In order to improve the vaccination campaign the stability of two vaccines was measured over 8 weeks. In both vaccines the drop of the virus titre was the highest when baits were placed in the sunlight, but, in the shadow, the virus was detected until day 53 of observation. The aim of this study is to summarise the current status of rabies and to look for the best solutions in the next vaccination campaign.

North American Vitis species and hybrids thereof have been the source of rootstocks for V. vinifera for the last century. Collection and evaluation of native Vitis in north-central Texas, western Texas, and New Mexico have been made to determine their current status. Known geographical pockets of grapevines were visited, with specimens taken and identified by comparison to herbarium collections and published descriptions. In locals where more than one species existed, many natural hybrids with varying morphological characteristics have become established. In North Central Texas, two areas were visited. The first was Tarrant, Parker and Wise counties where three grapevine species (V. mustangensis, V. cinerea var. helleri, and V. vulpina) and many hybrids were observed. The second was Wilbarger County where V. acerifolia was found growing in the south while V. ×doaniana was found growing in the north. West Texas was primarily populated with V. acerifolia with the exception of the Silver Falls Canyon area in Crosby County where hybrids of V. acerifolia, V. arizonica and V. riparia were observed. In New Mexico, two areas were visited: San Miquel County (North Central region), where V. acerifolia, V. arizonica, and V. riparia were observed and Eddy County (southern New Mexico) where V. arizonica was observed. A rich diversity of Vitis germplasm appears to remain in these habitats.

The Arkhangelsk region is one of 11 regions of the Russian Federation within the North-West Federal District (NWFD), which unites two economic regions — the North and North-West. Today it represents the largest region of the whole European part of Russia. The article discusses the changing role of the Archangelsk lands in the historical context and their ability to develop in the modern, sometimes not always simple conditions of globalization of the world economy, where international cooperation comes to the fore, based mainly in this particular case on the export of natural resources, which are rich territory. At this time, the economic activity of the Arkhangelsk region is characterized by the predominant raw material component. Based on this, the most important strategic goal is the reorientation of the regional economy to the production of products of deeper processing and to a certain extent with high added value. This refers to the processing industry. The author pays great attention to the problems of small business in local conditions and focuses on such leading segments of the entire industrial complex as the forest industry and shipbuilding. Due to its geographical position, which is favorable from many points of view, the port city of Arkhangelsk itself is considered as a base for the development of the Arctic territories of the Russian Federation and the further effective use of the Northern Sea Route (NSR). Sincere concern to the creator of the article is caused by the environmental problems of the Arkhangelsk region and measures taken to protect the environment.

Abstract The power generation system in Denmark is extensively based on small combined heat and power plants (CHP plants), which produce both electricity and district heating. This work deals with smaller plants spread throughout the country. Often a heat accumulator is used to enable electricity production, even when the heat demand is low. This system forms a very complex problem, both for dimensioning, designing and operation of CHP plants. The objective of the work is the development of a tool for the optimization of the operation of CHP plants. The optimization problem is a MINLP-problem of a very large scale. Therefore, a set of heuristic rules is formulated in order to reduce the size of the problem. Different cases are being tested, involving CHP producing units to cover the demand. The results show that it is of major importance to consider the operation of the plant in detail already in the design phase. It is of major importance to consider the optimization of the operation of a plant, even at the design stage, as it may cause the contribution margin to rise significantly, if the plant is designed on the basis of a detailed knowledge of the expected operation.
