Investment funds as institutional investors, who are on the financial market in the Serbia present somewhat less than ten years, still do not get to seriously increase the level of assets they ...manage. One of the main reasons for low level of business definitely is low and highly uncertain yields that are accompanying investments made into funds. Another, very important aspect that affects low financial assets that are managed by funds, is major lack of education on business investment funds on the individual investors' end. Financial education and promotion have emerged as significant activities for overcoming this problem. Continuous education for every segment of population and active campaign, not only for investment funds but also, state bodies and authorities, as well as other institutions, is the only way for quality information to reach out potential investors, upon which they will be able to decide about investing.
The aim of present research was to establish the role of epicuticular wax content in eight cabbage genotypes (four white hybrids and one red hybrid, two red varieties and one white variety) in the ...context of its natural resistance to attack cabbage flea beetles (Phyllotreta spp.) and cabbage stink bugs (Eurydema spp.), which are among the most important cabbage pests in southern Europe. For this reason and for the purpose of diminishing the use of synthetic insecticides against the cabbage pests the field experiments in 2006 and 2008 were conducted. We found out that individual cabbage genotypes – they had different epicuticular wax content – differ in regard to their susceptibility to attacks by the studied groups of harmful insect pests. The highest susceptibility to attacks by Phyllotreta spp. was confirmed for the hybrid ‘Cheers F1’, in the first year (1.68 ± 0.05), as well as in the second year of the experiment (2.87 ± 0.13). Cabbage stink bugs in both years of the experiment caused the highest extent of injuries on the hybrids ‘Destiny F1’, ‘Cheers F1’, and ‘Vestri F1’. In both years we found higher epicuticular wax content in red cabbage genotypes. In almost all studied genotypes we found a pronounced negative correlation between the content of epicuticular wax and the extent of injuries done by both groups of harmful pests. We have established that epicuticular wax is an important factor of cabbage's antixenotic resistance to attacks by cabbage flea beetles and cabbage stink bugs, and that the cabbage genotypes with higher content of this substance are consequently more suitable for environmentally acceptable manners of cabbage production.

Raziskava o vplivu nekaterih biofizikalnih (vsebnost epikutikularnega voska) in biokemičnih (obarvanost listov, skupni polifenoli in antioksidacijski potencial) dejavnikov na odpornost zelja ...(Brassica oleracea L. var. capitata) proti poškodbam, ki jih povzročajo kapusovi bolhači (Phyllotreta spp.), kapusove stenice (Eurydema spp.) in tobakov resar (Thrips tabaci), je potekala v letu 2010 na Laboratorijskem polju Biotehniške fakultete v Ljubljani. V poljski poskus je bilo vključenih 20 genotipov zelja in sicer 9 zgodnjih, 5 srednje zgodnjih in 6 srednje poznih genotipov (glede na dolžino rastne dobe), 3 rdeči in 17 belih genotipov (glede na barvo listov) ter 14 hibridov in 6 sort (glede na poreklo). Statistična analiza je pokazala, da biofizikalna in biokemična sestava listov zelja najbolj vpliva na odpornost te vrtnine na napad kapusovih bolhačev. Ti namreč kažejo šibko preferenco do zgodnjega in rdečega zelja ter do hibridov, ki imajo visoko vsebnost epikutikularnega voska (r2 = –0,6137, r2 = –0,7603 in r2 = –0,6812). Prav tako smo pri kapusovih bolhačih ugotovili močno negativno korelacijo med antioksidacijskim potencialom in obsegom poškodb pri srednje poznem zelju (r2 = –0,7185), pri rdečem zelju (r2 = –0,7811) in pri sortah zelja (r2 = –0,7802).
The main objective of this paper is to describe the development of the right to earnings compensation during a temporary disability to work. This right is of great importance in the system of health ...insurance, and therefore in social security as a whole. On the basis of this right, in the absence from work for medical reasons, the existence of the insured is not called into question. In Serbia, this right in the normative sense has a very dynamic development. No matter what has been introduced since 1945, in our country's socialistic social order, only a short period of funding for this right was financed from the budget. Since 1950, this right has been financed in a classical way, through contributions to compulsory social insurance. Apart from the fact that the right to remuneration has had a very dynamic development in terms of legislative activity, this right, regardless of its social component, was gradually reduced in order to accommodate the financial capabilities of society, ie. to ensure its financing to the extent that it is financially sustainable. Apart from the fact that this paper gives a normative presentation of the regulation of this right, exact financial indicators for its provision are given, which clearly show the importance of this right in terms of the overall health insurance system costs, and therefore the share of the same costs in the total health insurance expenditures as well.
The aim of this paper is to analyze the relationship between the Fund for Social Security of Military Insurers and the Republic Health Insurance Fund through the aspect of more efficient use of ...health insurance funds. Analyzing this relationship, the system of health care in the Republic of Serbia and the health insurance system are essentially considered. Taking into account the specifics of the social protection of military insurers, efforts are being made to find out the direction and improvement of relations with the civilian health care system. Only the proactive relationship between the military and the civilian health system and the health insurance system is a condition of better health care for the insured of both funds, as well as more efficient use of health insurance funds. Health protection of the population is one of the most important social priorities and as such it must be given special attention. The right of the individual to health care, but also to other forms of protection, is realized within the framework of social insurance. Health care, and therefore the health insurance system of military insureds, developed in accordance with the specifics related to the military system itself. Fully respecting the autonomy of the said system, the development of insurance in this area evolved along with changes in the prevailing civilian health insurance system. The system of health care and health insurance is one of the most important systems in each country. The efficiency and cost-effectiveness of the functioning of this system is a challenge for every national economy. The goal that needs to be achieved is to achieve the best health care of the nation by means of available health insurance. The system of compulsory health insurance in the Republic of Serbia is implemented through a unique state organization - the Republic Health Insurance Fund. When it comes to health insurance and the protection of civil and military insurers, it is clear that these are two completely separate and independent systems that have a lot of common points and whose mutual cooperation and shared use of resources should lead to positive effects as a whole. The financial aspect, which is especially reflected through the health insurance system, is one of the most important factors because it directly affects the scope and quality of the entire health care system. Considering and analyzing the complexity of the mutual relations between the civilian and military health and social security systems, and consequently the health care system, some of the possible proposals have emerged for improvement of one of the most important aspects of every society - the health of the nation.
Every citizen of the Republic of Serbia has another opportunity to invest and increase their income - investment funds. The first funds began its operations shortly after adoption of the Law on ...Investment Funds in 2006 which provided legal framework for their establishment and doing business. The initial years of business were marked with negative influences as a result of great crisis within world markets. The main reasons for limitation of greater investment of individual investors in investment funds are both low standard and financial status of citizens of Serbia, underdeveloped national economy, underdeveloped financial markets and consequently, low and negligible investment funds' income.
This paper shows the use of membrane filters in adsorption of solution of tetracycline hydrochloride on graphene materials. The adsorption process was monitored at different wavelengths, different pH ...values at certain time intervals.
The absorbances of the solutions were measured by UV-Vis spectrophotometry at two wavelengths (275 nm and 356 nm), and three pH values (pH 4, pH 7 and pH 10) every 90 minutes for 6 hours of monitoring, with constant stirring in an ultrasonic bath.
The results showed decrease in absorbance at both wavelength and in all three pH values which proved the adsorption of tetracycline hydrochloride on GO and rGO. The largest decrease in absorbance was 98.1%. The most suitable pH value for adsorption was pH 4.
This paper used a unique approach to filtration through membrane filters, which in the future could lead to the development of membrane filters based on graphene materials.
In a two-year field experiment, we studied the extent of damage caused by cabbage stink bugs (Eurydema spp.) on the frame leaves and the outer leaves of cabbage heads in relation to genotype color. ...We established that the extent of damage varied with genotype color. In both years of the experiment, the affinity of Eurydema spp. toward green genotypes was significantly greater on the first four assessment dates (from the third decade of May to the third decade of June), while on the remaining dates (from the third decade of July to the second decade of August) we did not establish any differences between the white and red genotypes. Cabbage stink bugs first appeared on white cabbage genotypes. The antioxidative potential conditioned by the content of anthocyanins was significantly higher on the red cabbage genotypes. Research shows that higher antioxidative potential is related to a lower extent of damage caused by Eurydema spp. The average value of antioxidative potential in the cabbage varieties was 0.58 mmol/100 g of the sample, while in the hybrids it was 0.47±0.01 mmol/100 g. We confirmed significant differences in values of antioxidative potential between red (0.68 mmol/100 g) and white (0.48 mmol/100 g) cabbage genotypes. Between mid-late (0.55 mmol/100 g) and mid-early (0.53 mmol/100 g) cab- bage genotypes we did not establish differences in antioxidative potential levels, while the average value of this parameter in the early genotypes (0.46 mmol/100 g) was significantly low. We established that the color of plants (cabbage) represents one of the successful factors of antixenosis and has the potential for reducing the damage caused by cabbage stink bugs in environmentally acceptable systems of cabbage production.
To assess the association between vitreous hyper-reflective dots (VHD) and the macular thickness changes following uneventful phacoemulsification.
In this prospective cohort study optical coherence ...tomography (OCT) examinations were performed preoperatively and 1 week, 1 month and 3 months postoperatively in patients undergoing cataract surgery. OCT images were analyzed for retinal central subfield thickness (CST) and preretinal VHDs. Surgeries were recorded for the assessment of lens fragments in the space of Berger.
111 eyes of 97 patient were enrolled of whom 69 (62.2%) were female. VHDs were seen in 25 eyes (22.5%) at week 1; in 21 eyes (18.9%) at month 1 and in 3 eyes (2.7%) at month 3. In all eyes with VHDs retro-capsular lens fragments were visible immediately after phacoemulsification. The number of VHDs significantly decreased over the postoperative period. There was a moderate correlation between the number of VHDs and CST at 1 month (r = 0.426, p<0.001). In eyes with VHD the CST averaged 238.8±17.6 μm (214-266) at 1 week; 276.1±63.5 μm (231-481) at 1 month and 285.1±122.3 μm (227-785) at 3 months. In eyes with no detectable VHDs CST averaged 235.9±23.3 μm (192-311) at 1 week; 240.1±21.6 μm (200-288) at 1 month and 242.2±21.3 μm (205-289) at 3 months. Although the differences among the assessment points were relatively low, there was a significant difference in general (p<0.001, Friedman test).
In conclusion, VHDs seem to cause macular thickening throughout the postoperative course. The origin of VHDs is still unknown; however, they presumably represent lens fragments that provoke subclinical inflammation.
