The impact of the Quaternary glaciations on the Durmitor mountains (Montenegro) as understood from detailed geomorphological mapping
Geomorphology of the Durmitor Mountains and surrounding plateau Jezerska PovrÅ” (Montenegro)
The geomorphological map of the northeastern Durmitor Mountains and the plateau Jezerska Povrs. (1: 10,000, 47 km(2), Montenegro, Dinaric Alps) was prepared from an intensive fieldwork campaign and remote sensing analysis, and was compiled within a GIS. The basic components of the legend are (i) processes/genesis, (ii) materials, (iii) morphometry/morphography, (iv) hydrography, (v) vegetation and (vi) anthropogenic features. The geomorphological setting of the area consists of Mesozoic limestones which are physically deformed by Quaternary glacial and periglacial activity and chemically affected during interglacials. Glacial deposits on the plateau of three middle-to-late Pleistocene glacial phases are intersected by a well-developed network of palaeo meltwater channels. In the mountains, Holocene glacier retreat left behind a series of well-preserved recessional moraines. The map serves as a valuable tool for Quaternary research in the Durmitor Mountains, and also in other mountains of the Western Balkans
Uticaj setvene norme na prinos i kvalitet sena lucerke
The objective of this research was to determine dry matter yield (t ha-1) and leaf
portion (g kg-1) as affected by different seeding rates. Four alfalfa varieties, two cutting
regimes (I ā early, cuts at the 10% bloom stage; II ā medium, cuts at the 50% bloom
stage), and two seeding rates were compared. Higher seeding rate did not produce
higher dry matter yield. Cutting in different phenological stages of alfalfa plants had no
significant effect on the yield. Leaf portion significantly correlated with the cutting
regime, while seeding rate did not show statistical correlation.Tokom 2010-2011. godine ispitivan je uticaj razliÄitih koliÄina semena za
setvu na prinos sena (t ha-1) i udeo lista (g kg-1) u prinosu lucerke. U ogled su ukljuÄeni
sledeÄi faktori: dve setvene norme (8 i 16 kg ha-1); dva sistema kosidbe (I-rani, koÅ”enje
u fazi 10% cvetalih biljaka; i II-srednje rani, koŔenje u fazi 50% cvetanja); 4 sorte
lucerke (Banat VS, Nijagara, NS Alfa i NS Mediana ZMS V). Prinos suve materije se
nije znaÄajno poveÄao poveÄanjem setvene norme. Setvom 16 kg ha-1 dobijen je isti
prinos kao i setvom 8 kg ha-1. Kosidba u razliÄitim fazama razviÄa biljaka lucerke nije
znaÄajno uticala na formiranje prinosa. Udeo lista u prinosu znaÄajno je zavisio od
sistema kosidbe, dok veÄa koliÄina semena za setvu nije uticala na poveÄanje kvaliteta
sena lucerke
Study of the Electrochemical Oxidation of Reactive Textile Dyes Using Platinum Electrode
Textile industries are widespread in developing countries. Among the various processes in the textile industry, the dyeing process uses large volumes of water for dyeing, fixing and washing. Textile industry wastewater is characterized by intensive color and high chemical oxygen demand (COD) concentrations that discarding of these toxic wastewaters to the environment will cause a major problem. In this study electrochemical oxidation of reactive textile dyes: Reactive Blue 52, Reactive Black 5, Reactive Green 15, and Reactive Yellow 125, using platinum anode was examined. Electrolysis is carried out in electrochemical cell containing membrane which is standard membrane in industry. Membrane separated anodic and cathodic area. Supporting electrolyte was 0.1M sodium sulfate which is also present in real textile effluents. Applied voltage of 6, 12 and 24V, and influence of membrane on electrolysis were examined on model dye (Reactive Blue 52). Highest degradation degree for model dye was achieved at 12V, so electrolysis of other dyes was done on this voltage. COD value of all dyes dropped after 60 minutes of electrolysis below a measurable level ( LT 30mg/L O-2), except Reactive Black 5 whose COD reduction was 57.95% with membrane and 35.28% without membrane applied. Complete decolorization was achieved after 10 to 60 minutes for all dyes. Degradation products of model dye Reactive Blue 52 were monitored with HPLC, and influence of pH on decolorization was also examined on model dye

Immune Response in Severe Infection: Could Life-Saving Drugs Be Potentially Harmful?
Critically ill patients suffer a high rate of nosocomial infection with secondary sepsis being a common cause of death. Usage of antibiotics and catecholamines is often necessary, but it can compromise complex immune response to infection. This review explores influence of these life-saving drugs on host immune response to severe infection

ZnaÄaj leguminoza za organsku poljoprivredu
Legume crops are primarily grown for their quality and value-added traits. Apart from their role in human and animal nutrition, they are being increasingly used as medicinal plants in pharmaceutical production. Legumes are of great interest in cultural practices under all farming systems, particularly organic agriculture. They are essential in crop rotations, and are among the most desirable preceding crops that create favourable biophysical conditions within the soil, with high levels of nitrogen naturally accumulating. There are many legumes suitable for companion and cover crops, and in the absence of quality farmyard manure they are sown for green manuring. In organic farming, legumes are environmental corridor components involved in biodiversity protection and restoration, as evidenced through increasing numbers of beneficial species in these isolation belts.Leguminoze su grupa biljaka koje se prvenstveno gaje zbog njihovog kvaliteta i velike upotrebne vrednosti. Osim za ishranu ljudi i domaÄih životinja, sve viÅ”e se koriste i kao lekovite biljke za proizvodnju razliÄitih farmaceutskih preparata. Leguminoze imaju izuzetan agrotehniÄki znaÄaj u svim sistemima poljoprivredne proizvodnje, a posebno u organskoj poljoprivredi. U plodoredu su nezamenjive kao jedan od najpoželjnijih preduseva, koji zemljiÅ”te ostavlja u povoljnom biofiziÄkom stanju, sa visokim sadržajem na prirodan naÄin akumuliranog azota. Veliki broj leguminoza je dobar za gajenje u združenim i pokrovnim usevima, a u nedostatku kvalitetnog stajskog Äubriva, seju se kao siderati. U organskoj poljoprivredi mahunarke su sastavni deo eko-koridora koji imaju ulogu da zaÅ”tite i obnavljaju biodiverzitet, Å”to se manifestije poveÄanjem broja korisnih vrsta u ovim izolacionim pojasevima
