The article deals with the problem of debug of hardware computational units intended for stream data processing on FPGA. Modern solutions are usually oriented to debug of a hardware unit implementation in a simulator with some model input data or to observing the implemented design in the prototype with real target system environment. However effective analysis and debug of implemented computational algorithms requires combined debug with test data exchange between hardware unit model in simulator and its implemen...

Environmental pollution with heavy metals is important by its effects on all the segments of the ecosystem: soil, water, air, plants, animals, and humans. Humans and animals contamination is achieved either by direct contact with polluting particles, or indirectly by consuming the contaminated vegetables. It is also known the human contamination by eating products obtained from animals bred in polluted areas. The effects of heavy metal pollution are well-known at the level of soil and superior organisms. Soils con...

Many fungi, including keratinolytic species, occurring in sewage sludge and sludge-amended soils possess potential pathogenic properties to humans and animals. For this reason, apart from bacteria, zooparasites and viruses, these fungi pose health risk to wastewater treatment plant and agriculture workers. Assessment of this risk was the aim of the present study. The sludge and sludge-amended soils were provided from one of the Polish wastewater treatment plants. The wastewater treatment technology and the sludge ...

The buildings contribute largely to emissions of greenhouse gases. By bringing about changes in this sector, we can achieve significant reductions in these emissions, with an important role in achieving the EU objectives on Near Zero Energy Building (NZEB). According to the European Council, the energy consumption of buildings represents 40% of total energy consumption, contributes to 36% of the emission of greenhouse gases. Worldwide population growth, especially in urban areas, causes an increased consumption of...

This paper deals with the burning of edible vegetable oils. Their primary use is in the field of food preparation, but they are increasingly being used as a basic raw material for biodiesel production.

Snow samples were collected in each sampling plot taking from 1.0 to 1.5 kg of snow. The average depth of snow was between 6 and 10 cm. The aim of study was to determin...

The Danube Delta is declared the biggest natural reserve in Europe. Due to the fact that the Danube River is a main water collector in Europe, it flows all the impurities and pollutants that people discharge into the rivers which are the tributaries of Danube. The present study is a warning against water pollution in the Danube Delta, pollution that may affect biodiversity. Babadag Lake is part of Razim - Sinoe lagoon system, included in the Wetlands Protected Area under the Ramsar Convention, and together with th...

One of the main worldwide issues today is represented by the need of protecting the environment and human health. This requires prevention and monitoring the pollutant contamination of the environment and food products. Toxic heavy metals may accumulate in plant tissues and inhibit most physiological processes at all metabolism levels. They inhibit growth, photosynthesis, water uptake and nitrate assimilation. Romania is a resourceful country and a number of energy and mineral resources can be found on its territo...

The manufacturing and processing of metals is connecting with large number of different types of wastes. One kind of these wastes are dusts and sludges which arise as a result of the melting processes or in the machining of castings. Flue dusts from melting processes are captured most often on filters, scrubbers or in Venturi scrubbers. Dust particles resulting from the machining of castings (grinding and blast cleaning) remain in the grinding rooms or they are sucked and collected on filters. Whereas these dusts ...

Hydric soils, named as Gleysols and Stagnosols, have formed under conditions of saturation, flooding or ponding long enough during the growing season to develop anaerobic conditions in the upper part of soil profile. If microbes are active (>50C), if the soil is saturated with stagnant water, and there is a source of usable organic matter in the soil, then redox feauter will result. In the region Banat, situated in the north west of Romania, there is a large area with soils that have water excess: hydric soils, wi...

Geochemical barriers are the special type of natural systems boundaries. They prevent the penetration of some of substances and are open for the migration of others. For the inorganic substances, especially for the metal ions the barriers are studied enough completely: the models of barriers are developed, the penetration and accumulation kinetic is assessed. But for the organic compounds the role of the geochemical barriers is practically not studied. Especially important are such assessments from the point of vi...

The Kungurian salt domes are widely pervasive in the Pre-Caspian depression, so that the post-salt Upper Paleozoic and Mesozoic deposits disturbed considerably by salt tectonics. Salt structures formed mainly in the upper Permian time, at the end of which salt massifs broke this thick stratum and they were intensively dislocated. In the Mesozoic period, there was a moderate redistribution of salt, which resulted in uplift of Triassic to Cretaceous deposits on the top of salt bodies. Salt movements affect the posts...

Shale gas potential assessments completed in 2010 for the Baltic Basin (BB) were very optimistic.

The ecological situation of the Arctic and sub-Arctic areas has been given special attention due to their extremely vulnerable environment. In comparison with other areas, the Arctic remains a clean environment, but heavy metals occupy a special place among priority pollutants. There are a lot of studies of heavy metals in the soil, but not enough information on the joint content and physicochemical factors that affect the metals accumulation in the Arctic soils. Therefore, this paper presents identification of co...

This study uses a pooling approach to identify catchments with similar flood characteristics in the Alpine-Carpathian region. The identification of similar regions is performed using the nonhierarchical k-means clustering algorithm and different sets of catchments characteristics (catchment area, forest cover, mean catchment elevation) and flood seasonality characteristic (concentration of flood around the mean date of flood occurrence). The optimal number of cluster is determined using the silhouette method. The ...

The central and northern parts of Poland are covered by a thick blanket of Pleistocene post-glacial sediment. Directly beneath this material lie loose, or of early diagenetic overprint, Neogene formations, mainly Miocene sediment. The thickness of Quaternary sediments in the northern part of the country locally exceeds 300 m. The loose and highly, internally diverse subsurface complex considerably hampers the completion of seismic surveys, especially those including the seismic reflection method. The basic issue o...

The key issue of Polish municipal waste management system is still too little progress in subjecting waste to recycling processes. Legislative changes implemented in this area are intended to build a rational and integrated system that meets the stringent requirements of the European Union. A set of requirements for the formal regulations generates the need for a comprehensive approach to waste flows between participants of the system. Adoption of such a course of action enables to meet the mandatory requirements ...

In recent decades the increase of the frequency of flash-flood conditions requires a correct identification of potential flood areas where these hydrological risk phenomena appear in Moldavian Plain. To identify the basins and localities exposed to flash-flood was used physiographic method. This method allows the opportunity to identify the river basins with the concentration of water from precipitations in less than 6 hours. Through successive sorting of the basins which may generate the flash-flood was identifie...

In the paper the precipitation of arsenic and iron from an acid drainage water of the Berikul mine wastes by using lime milk, NaOH, and Na2S were studied. The wastes were stored in the southern part of the Komsomolsk tailings impoundment, near the Komsomolsk settlement (Kemerovo region, Russia). The interaction of natural waters with the wastes produced ultra-acid drainage with a pH of about 2, with arsenic content of 1.3 g/l and iron - 6.5 g/l. The results of in situ experiments showed that adding lime milk and s...
