Given an example watershed, calculation of the long-term average annual soil loss by the universal soil loss equation (USLE) is analyzed taking into amount the Slovak and Polish approaches. Six factors are considered the rainfall erosivity factor (R), the soil erodibility factor (K), the topographic factors (LS) and the cropping management factors (C and P). Differences in input and methodology are highlighted. The example micro-watershed (the Matny stream basin in the Beskid Wyspowy, the western Carpath, Poland) ...

Water Framework Directive 2000/60 / EC is considered a progressive and innovative legislative measure which should lead to improved of surface water in Europe. One important factor contributing to the impairment of surface water quality is the use of chemical and organic fertilizers, which through runoff or leaching in water table can cause the phenomenon of pollution of surface waters and groundwater. In a river basin, the factors that determine the nutrient loads are: industry, urban sewage, atmospheric depositi...

The biggest river in the Kosovo area is White Drin. Last 60-ty years, in Kosovo, three state power has been changed, therefore we have observation of hydro-meteorological data, of three stages. Those data are not complete. There are two serious water resources master plans, of year 1983 and of 2008, but both have used data of period 1952-1986. The idea of this article, is to complete, calibrate and to validate existing data, of daily average flows, until today, in order to study water regime of White Drin river, f...

Carrot culture is highly dependent on soil, silty-clay or silty soils with high permeability and free of weeds are preferred. Weed control is a very important part of the production technology for plants. Chemical weed control has been found to have some advantages of which we mention: it is less labor-intensive, increases productivity, reduces the number of passes on farmland and increases production. The main purpose of this paper was to provide the most efficient solution for weeds control in carrot crops, usin...

This study investigates the weed vegetation in vineyards of Rahovec region in Kosovo. Along with far-reaching political and socio-economic alterations, agricultural land use has changed in the recent past in the Kosovo. To increase the knowledge on the weed vegetation in vineyards, we recorded the vegetation of 100 plots with a standard plot size of 25 mпїЅ. To avoid edge effects, the minimum distance of each plot to the field border was 10 m. The location of each plot was documented with the help of a GPS using t...

The aim of this study was to investigate weed flora in pepper crop on the Dukagjini plain in Kosovo. The arable weed vegetation of Kosovo has been affected by multiple environmental features and management measures on various spatial scales in the past. Weed flora in pepper crop on the Dukagjini plain was not studied in detail in the past; thus, data are insufficient and incomplete. To increase the knowledge of weed flora in pepper crop on the Dukagjini plain, we recorded the flora of 50 plots with a standard plot...

The interpretation of well tests is a tool for the detection of well and reservoir problems, which based on the determination of several parameters such as permeability, skin, average reservoir pressure, flow capacity (kh ), effective length, boundary reservoir, and type of wellbore storage, etc. The knowledge of these parameters will allow us to make the production forecast and the resolution of production problems. For this, We have chosen six production wells located in the Haoud Berkaoui oil field, the interpr...

Wettability as a rock-fluid interaction property is well recognized to affect the multiphase flow in hydrocarbons reservoirs. It impacts on the petrophysical properties of reservoir rock including relative permeability, capillary pressure, electrical properties and enhanced oil recovery. The three most commonly states are differed of wettability for hydrocarbon fields, these include: water wet, oil wet and mixed. USBM and Amott- Harvey laboratory methods are proposed as petroleum industry standards to estimate roc...

The aim of the article is to present a special model of emission changes compared to changes in the economic performance of EU countries. Because the expansion of international economic activity is associated with industrial structure and energy demands, governments must reexamine their policies that affect these urgent issues in the effort to achieve low air pollutants. The article deals with the relationship of GDP per capita and NOx emissions per capita. Within the examination of the growth or decline in NOx em...

The urban sprawl has an important impact on the socio-economic evolution of a city as well as on its environment. A defining characteristic of the western European capitalist city, the urban sprawl was not often observed in the urban areas of the Eastern Europe. However, it has become more and more relevant after the 90s because the transition to the post-socialist era determined an increasing development of the sub-urban areas of the cities from the ex-communist bloc. This paper studies the case of the post-socia...

The basic stage of the modern approach to calculation of a wind wave climate (long-term probability) includes the database formation using numerical hydrodynamic models. The input to such models is atmospheric pressure or wind velocity at some height over sea surface. This information extracted from the reanalysis data. Initially reanalysis intended for research of global processes without description of the extreme phenomena. For this reason, for calculations of a wave climate the reanalysis data have to be corre...

The paper presents the experimental analysis of a small scale building model (1:30), tested into a wind tunnel with atmospheric boundary layer. The objective of the study is to determine the wind influence on the ventilation of a double skin faпїЅade channel (DSF). It was achieved by conceiving and implementation of an experimental program using a wind tunnel. During the experimental work the wind effect over the ventilation of the vertical channels of double skin faпїЅades is evaluated for multiple velocities. Fo...

X-ray absorption near-edge (XANES) spectroscopy is an effective modern tool that can provide unique information on local atomic structure (bond lengths and bond angles) of geological materials. To extract such information with high precision from experimental XANES spectra, advanced theoretical analysis based on supercomputer modeling is needed. XANES spectroscopy and computer modeling have been applied to investigate local atomic structure of some terrestrial and extraterrestrials geological materials. XANES iden...

Biogenic origin of the carbonate reef build-ups poses multiple questions associated with spatial porosity distribution in corresponding hydrocarbon reservoirs. Consequently, this paper focuses on 3D characterization of the voids observed within chosen carbonate samples. Not only the pore type and geometry are interpreted, but also the origin of pores is attempted to be resolved. Zechstein (Permian) biogenic reef carbonates were examined. The rocks have been withdrawn from the central part of the isolated Wielichow...

Egg yolk pigmentation is one of major quality attribute linked to consumer requirements concerning eggs. The colour of the egg yolk is a dietary response, depending on the levels of carotenoids present in the feed. The purpose of the present study was to investigate the effects of feed supplementation with dried tomato waste in commercial laying hens on egg production, egg quality, egg yolk colour and carotenoid composition. The hens were fed the basal diet (BD) and the diet supplemented with 7,5% dried tomato was...
