OBTAINING LONG-TERM RESIDENT STATUS IN THE EUROPEAN UNION
This paper deals with obtaining long-term resident status in the European Union under Directive 2003/109/EC and problems arising from certain provisions. While enhancing the rights of legally resident third-country nationals, the Directive is in some aspects incomĀ¬patible with the case law of the Court of Justice regarding citizens as well as international agreements regarding the free movement of perĀ¬sons. At the same time, the practical applicability of certain provisions is doubtful due to the wide margin of discretion given to Member States
Copper Accumulation in Vineyard Soils: Distribution, Fractionation and Bioavailability Assessment
Heavy Metals Accumulation in Topsoils from the Wine-growing Regions Part 1. Factors which Control Retention
The problem of exposure of agricultural soils to different anthropogenic inputs of heavy metals has been investigated in soils from two wine-producing subregions in northwestern Croatia. The aim of this study was to explore :(i) the main soil properties and topsoil accumulation of heavy metals in vineyards under long-term cultivation, and (ii) the origin and the preferential feature of metal retention in vineyard topsoil using the multivariate statistical method. The investigated area was marked on regular square grid with 1-km spacing. Topsoil samples (0-10 cm) were collected from each sampling point and analyzed for soil chemical properties, particle size distribution and heavy metal concentrations after aqua region digestion. All soil data were incorporate into the GIS base. Summary statistics of the data set were first calculated to evaluate the distributions, and afterward processed by means of R-mode factor analysis, applying the varimax-raw rotational technique. Anthropogenic input of metals in soils of the studied wine-growing regions mostly originates from agrochemicals, since the direct influence of the urban environment or industry is almost negligible. Accumulation of copper and zinc in topsoil, determined in this research, is the most common effect of continuing fertilization and protection against diseases and pests in vineyards
Polemike u srpskoj filozofiji 1990-2010
This paper analyzes several significant polemics in Serbian philosophy, published in philosophical journals and daily papers during past two decades. These are polemics between Milorad BelanÄiÄ and Slobodan ŽunjiÄ, Nenad DakoviÄ and Slobodan ŽunjiÄ, and Mihailo MarkoviÄ and Aleksandar Prnjat, respectively. In the first polemic, the two authors discuss the ontological status of several philosophical terms; in the second one, authors negotiate the importance of translating and publishing F. Copleston's A History of Philosophy, whilst in the third polemic, the two philosophers discuss the problem of paternalism, suggesting redefinition of some aspects of this problem
ROLE OF HEAT PUMPS IN RISING THE ENERGY EFFICIENCY OF FAMILY HOUSES
Rad zapoÄinje kratkim uvodom u energetsku uÄinkovitost zgrada u Hrvatskoj i zakonima koji je obilježavaju. Zatim dolazi poglavlje s opÄenitim podacima o dizalicama topline ( princip rada, naÄini rada i uÄinkovitost toplinskih dizalica), a nakon toga slijedi kratak osvrt na sve izvore topline koje dizalica može koristiti u svome radu (tlo, voda, zrak, sunce). SljedeÄe poglavlje bazirano je na primjeni dizalica topline u svrhu poboljÅ”anja energetske uÄinkovitosti kuÄe, te nakon kratkog uvoda i stvarnog primjera analizirana je primjena dizalica topline zemlja-voda (sonda) na jednoj obiteljskoj kuÄi u Osijeku. Nakon dobivenih rezultata napravljena je usporedba izvora topline za grijanje navedene kuÄe izmeÄu prirodnog plina, loživog ulja i dizalice topline zemlja-voda
The antioxidative protecting role of the Mediterranean diet [Antioksidativno protektivno djelovanje mediteranske dijete]
Recent meta-analysis shows that adherence to a Mediterranean diet (MD) can significantly decrease the risk of overall mortality, mortality from cardiovascular diseases, as well as incidence of mortality from cancer, and incidence of Parkinson's and Alzheimer's disease. All of these diseases could be linked to oxidative stress (OS) as antioxidative effect of MD is getting more attention nowadays. Although a lot of research has been done in this area and it suggests antioxidative protective role of MD, the presented evidence is still inconclusive. The aim of this paper is to review studies investigating the effect of MD on OS, as well as to identify the areas for further research
Comparison of Transpiration Models in Tomato Soilless Culture
A two-year greenhouse study was performed to determine the possibility of estimating the transpiration rate in hydroponically grown tomato on the basis of climate parameters. Transpiration rate, determined by the water balance method on different substrates, was compared to the transpiration rate calculated using the Penman Monteith equation. Regression analysis of the comparison of two different approaches to water consumption determination confirmed that the transpiration rate of greenhouse grown tomato for the studied area can be estimated with high accuracy (R2 > 0.95)
