The Social Choice Theory: Can it be Considered a Complete Political Theory?

Social choice theory (SCT) deals with the aggregation of individual preferences in order to arrive at social preference orders, i.e. at the ‘general will’. The present paper examines whether SCT could be regarded as a complete political theory. SCT is evaluated against seven criteria, proposed by Martha Nussbaum, that a political theory needs to fulfill in order to be regarded a complete political theory. These criteria are: understanding of material need; procedural justice; liberty and its worth; racial, ethnic and religious differences; gender and family; international relations; and moral psychology. The analysis showed that SCT is strong at problems of procedural justification, distributive justice and some problems of ethics. It is weaker on the issues of moral psychology, and justice between nations. It is neglectful concerning the issues of racial, ethnic and religious inequality, and issues of gender and family. The paper concludes that the SCT can have an important place within more comprehensive political theories, but cannot claim itself to be a complete political theory

Revegetation of ski runs in Serbia: Case studies of Mts. Stara Planina and Divčibare

Revegetation is the most sustainable method of soil stabilization at ski runs. In order to establish a stable plant community, it is recommended to use native species. However, non-native species are most often used. In this paper the revegetation of ski runs at two ski resorts is investigated: Divčibare and Stara Planina. Seven species were used for the revegetation of the ski run at the Divčibare ski resort of which six species were native. Six species were used for the revegetation of the Stara Planina ski resort, of which two species were native. It was established that the plant species used in the seed mixtures were suitable for erosion control at the investigated ski resorts

Sadržaj i hemijski sastav etarskog ulja anisa

The field experiments were carried out during 2011 and 2012 in three localities in Vojvodina (Serbia) with the application of six different fertilizer regimes aimed at determining the content and composition of the aniseed essential oil. It was found that the average essential oil content of aniseed, obtained by hydrodistillation, was 3.72%. The weather conditions during the year and the locality had a statistically significant effect on the essential oil content, while different source of fertilizers was not statistically significant for the essential oil content and its composition. Essential oil composition was determined using GC–MS technique, and a total of 15 compounds were identified. It was found that the major component was trans-anethole, 94.78% on the average, and the coefficient of variation was 2%. The second most abundant component was γ-himachalene with 2.53% (CV 28%). All other components were present in less than 1%.U radu su prikazani rezultati ispitivanja količine i hemij- skog sastava etarskog ulja anisa gajenog tokom 2011. i 2012. godine na tri lokaliteta u Vojvodini (Srbija), pri primeni šest različitih vrsta đubriva. Utvrđeno je da je prosečna količina etarskog ulja u plodovima anisa dobijena metodom de stilacije vodenom parom 3.72%. Vremenski uslovi tokom godine i lokalitet imaju statistički značajan efekat na sadržaj etarskog ulja i njegov hemijski sa stav, dok primena različitih vrsta đubriva ne utiče na ove parametre. Hemij ski sastav etarskog ulja određen je primenom GC–MS analize, pri čemu je identifikovano ukupno 15 komponenti. Ustanovljeno je da je glavna komponenta transanetol, se prosečno 94,78%, i koeficijentom varijacije 2%. Druga najzastupljenija komponenta bila je γ-himahalen sa 2,53% (CV 28%). Sve ostale komponente bile su prisutne sa manje od 1%

Volatile Constituents of Different Plant Parts and Populations of Malabaila aurea Boiss. from Montenegro

The volatile constituents of different plant parts and populations of Malabaila aurea Boiss. from Montenegro were obtained by simultaneous distillation-extraction and analyzed by GC-FID and GC-MS. A total of 12 samples were examined and 45 compounds were identified. The volatile content of different M. aurea populations was very similar, while the volatile fractions obtained from different plant parts showed significant qualitative and quantitative differences. The most abundant compounds found in stems & leaves were apiole (51.0-56.3%), myristicin (16.3-25.4%), and falcarinol (4.1-10.7%). The roots showed the same major components, but with different relative abundances: 30.9-49.1% of apiole, 12.9-34.7% of falcarinol, and 9.9-31.1% of myristicin. The volatile constituents of fruits & flowers were remarkably different, containing up to 71.2-80.5% octyl butyrate, 11.4-18.0% octanol, and 2.7-6.8% octyl hexanoate. The results were discussed as possible indication of relatedness of Malabaila aurea and Pastinaca sativa (parsnip)

MEDICINAL PROPERTIES OF BUCKWHEAT PRODUCTS AND HONEY IN COMPLIANCE WITH FOOD SAFETY REGULATORY REQUIREMENTS

Buckwheat (Fagopyrum esculentum Moench) is a gluten-free pseudo-cereal and honey plant. Buckwheat grain yields vary greatly and depend on the genotype, agro-ecological conditions of production and harvesting method. The grain yield of the 'Novosadska' variety variеs 1.5-3 t ha-1and the honey yield amounts and more than 300 kg ha-1. Buckwheat grain contains: carbohydrates, proteins, fats, organic acids and rutin (quercetin-3-rutinosid), minerals (potassium, phosphorus, calcium, magnesium, sodium, iodine, zinc, bromine and iron), vitamins (D2-ergokalciferol, D3-holekalciferol, P-bioflavonoids, vitamins group B: B1-Thiamine, B2-Riboflavin, B3-niacin, B4-Choline, B5-Pantothenic acid, B6-Piridoxin, B9-Folate; and vitamin E-Tocopherols. 'Novosadska' buckwheat contains the highest level of phenolic acids, proanthocyanidins, flavones and flavonols. Buckwheat honey is dark color, which it gets from polyphenols. Polyphenols is antioxidants, organic compounds which affect the quality of food, especially the color and taste. In accordance with the law on food safety, the interests of consumers must be ensured the highest level of protection. Phenolic antioxidants from honey are bioavailable and increase the antioxidant activity of plasma. Buckwheat honey has a beneficial effect on bronchitis and cough, hypertension, arteriosclerosis, of heart disease, liver and intestinal diseases and has antibacterial effects

Trophic chain Yersinia pseudotuberculosis

This paper tries to reproduce two types of trophic chains on the example of an aquatic ecosystem model, with the participation of planktonic and benthic organisms: "yersinia - infusoria - daphnia - fish" and "yersinia - insect larvae - fish". The concentration of Yersinia pseudotuberculosis during primary infection (infusoria culture medium) was 109/ml. In the first hours after infection, the concentration of bacteria in the infusoria decreased (105cfu/mass ). In daphnia, which consumed infected infusoria, the concentration of Yersinia pseudotuberculosis decreases in the first 3-5 days (from 105 to 103 cfu/10 individuals), then the reproduction of Yersinia pseudotuberculosis in daphnia continues, and on the 11th day it reaches 107 cfu/10 individuals. The concentration of Yersinia pseudotuberculosis in the intestines of fish fed infected daphnia (107cfu/10 individuals) is continuously decreasing: 105 cfu (after 24 hours) and 102-101 cfu/individuals (after 15-30 days)
