Kadovic Ratko,Belanovic Sne?ana,Kneevic Milan,Danilovic Milorad
Glasnik ?umarskog Fakulteta , 2012, DOI: 10.2298/gsf111230002k
Abstract: The content of organic carbon (C) was researched in topsoil layers (0-20 cm) in the most represented soils of forest ecosystems in central Serbia: eutric ranker, eutric cambisol and dystric cambisol. The soils were sampled during 2003, 2004 and 2010. Laboratory analyses included the soil physical and chemical properties necessary for the quantification of the soil organic carbon in organic and mineral layers. Mean values of the soil organic carbon (SOC) stores in organic horizons of the study soils varied between: 1.01±0.4 kg(C).m-2 (dystric cambisol), 0.90±0.41 kg(C).m-2 (eutric ranker) and 0.94±0.36 kg(C).m-2 (eutric cambisol). Average values of organic carbon in mineral layers (0-20 cm) ranged between: 3.83±1.70 kg(C).m-2 (dystric cambisol), 6.26±3.41 kg(C).m-2 (eutric ranker) and 4.36±1.91 kg(C).m-2 (eutric cambisol). The average value of total organic carbon stock in the study soils (both organic and mineral layers) was 5.77 kg(C).m-2. This paper addresses the methodological aspects of regional estimation of soil organic carbon content as the potential to be applied in the National Forest Inventory Program.

The European journal of psychiatry (edición en espa?ol) , 2004, DOI: 10.4321/S1579-699X2004000200006
Abstract: los problemas de la maternidad en la adolescencia, que en condiciones normales son principalmente de tipo psicosocial y relacionados con la edad, son todavía más complicadas en las condiciones de riesgo que acontecen tras un parto exitoso en la vida de un refugiado, conllevando un riesgo adicional para una infancia feliz y acarreando posibles consecuencias que pueden afectar el desarrollo psicológico del ni?o. por todo ello, debería prestarse especial atención y ayuda a las madres jóvenes, ense?ándoles en primer lugar cómo comunicarse afectivamente con sus hijos, para que aprendan a interpretar las necesidades de los ni?os y satisfacerlas adecuadamente. además, se requieren medidas adicionales de intervención con métodos estándar de prevención y tratamiento del abandono infantil, bajo las condiciones de vida de los refugiados.

Medicinski Glasnik , 2011,
Abstract: Aim The aim of this research was to determine the risk for familyappearance of the recurrent headache (non-migraine and migraine). Methods The research was conducted in Vojvodina, the Northern Province of Serbia. The population of Vojvodina is around 2 millionpeople belonging to more than 20 different ethnic groups. During the 20-year period (1988-2008), 30,363 children aged 3 to 17 years were tested, independent of their place of birth. The presence of headaches similar to those tested was compared among all themembers of the family within three generations. Results Positive family data of the recurrent headaches were detected among 98.6% children with migraine headaches, 64.7% children with non-migraine headaches, and 32.4% children without recurrent headaches. The relation among the members of the nuclear family (contingency quotient of 0.429) was significantly stronger than the relation to the members of wider family (contingency quotient of 0.338). Conclusion The probability of a child having the migraine headacherather than the non-migraine one was very high for parents andhigh for father’s mother, while it was not significant for mother’smother, mother’s father and father’s father, having similar recurrentheadaches.
Genesis and characteristics of the soil in A-R stage in forest ecosystems of NP 'Tara'

Glasnik ?umarskog Fakulteta , 2009, DOI: 10.2298/gsf0999075k
Abstract: Different types of soil in A-R stage formed on limestone and serpentinite in forest ecosystems in NP 'Tara' were researched. Based on the specific effect of limestone on the soil genesis and evolution, two types of calcareous limestone bedrocks were distinguished: dense limestones, and soft, marly limestones. Three subtypes of black earth were studied on dense limestones. They are: organogenic, organo-mineral and brownised soils. One soil type was researched on soft, marly limestones: rendzina, the leached variety. One soil type was researched on serpentinites, within the A-R stage: humus-siliceous soil (ranker), subtype eutric ranker. This paper also presents the evaluation of ecological and productive characteristics of the study soils. If the soil is observed separately, regardless of the tree species growing on it, the soils in A-R stage in NP 'Tara' cannot be evaluated as highly productive. However, in all plant communities on the soils in A-R stage on limestone, the values of average volume, current volume increment, and basal area were high. The unfavourable physical characteristics of the soil in the area of NP 'Tara' are compensated by the effect of humid climate. On the study eutric humus siliceous soils in the area of NP 'Tara', in the natural and artificially established stands of Scots pine and Austrian pine, the ecological and productive value is conditioned by numerous factors and it is mainly limited by unfavourable physical characteristics. Regardless of the unfavourable ecological and productive characteristics of the soil, the natural and artificially established stands of Scots pine and Austrian pine are in the coeno-ecological optimum.
Rendzinas in the community of beech, fir and spruce with Scots pine in NP 'Tara'
Kne?evi? Milan,Ko?anin Olivera
Glasnik ?umarskog Fakulteta , 2010, DOI: 10.2298/gsf1001101k
Abstract: The rendzinas were studied in the community of beech, fir and spruce with Scots pine (Piceo-Fago-Abietetum subass. pinetosum silvestris), at the altitudes above 1,000 m, on steep slopes and warm aspects. The genesis and properties of these rendzinas were strongly affected by chemical composition, mineralogical structure and bedrock weathering. Soft limestones, which are characterized by low hardness and a higher content of insoluble residue, present the major impact on the physical and chemical characteristics of rendzinas. The presence of active carbonates in the profile causes a neutral to weak alkaline reaction, provides the constant buffering of organic acids and the formation of Ca-humates, and in this way also the formation of a stable organic-mineral complex, which in turn results in the formation of stable grainy soil structure.

Glasnik ?umarskog Fakulteta , 2006, DOI: 10.2298/gsf0693097k
Abstract: Very deep soils with clearly differentiated two-layered profile physiography were studied on the limestones of the mountain Magle . The very marked morphological differentiation of the profile is followed by significant textural differences and the variation of chemical characteristics of the soils. The profiles are 80-140 cm deep. The topsoil part of the solum, yellow-brown in colour, is 30-90 cm deep. Its textural class is silty-clay loam. Its chemical characteristics are very acid reaction and very low degree of base saturation. The relic (B) horizon is reddish brown in colour, and it is characterized by a very high percentage of the colloidal clay, it is highly plastic and it has a compact structure. Its reaction is mostly weak acid to neutral, and the degree of base saturation is very high. The study results confirm the hypothesis of a very high impact of the Aeolian process on the formation of deep two-layered profiles on Magle limestones.

Glasnik ?umarskog Fakulteta , 2005, DOI: 10.2298/gsf0592087k
Abstract: The soils in sessile oak forests were studied at three localities in the region of Northeast Serbia. Brownised dystrict humus-siliceous soil was studied on gneiss in M.U. "Zlatica" - N.P. " erdap", in the forest of sessile oak with fescue grass (Quercetum montanum subass. festucetosum heterophyllae). Dystric acid brown soil on gneiss was studied in the region of F.E. "Severni Ku aj", M.U. "Ravna Reka", in the community of sessile oak and hornbeam (Querco-Carpinetum moesiacum), and in the region of the Teaching Base "Majdanpe ka Domena" in M.U. "Crna Reka - Pek", in the forest of sessile oak with hairy sedge (Quercetum montanum subass. caricetosum pilosae) on schist's. Eutric brown soil was studied on amphibolite schist and on basic and neutral eruptive rocks in the region of N.P. " erdap", in M.U. "Zlatica", in the typical sessile oak forest (Quercetum montanum subass. tipicum).
