Tobacco (Nicotiana tabacum L.) belongs to the group of plants that produce agricultural raw material. Besides leaves, which are used to satisfy the passion for smoking, tobacco can be used for producing oil and biodiesel, because it contains 30-40% of vegetable oil. Because of its content of citric acid, tobacco can be used for production of dyes and varnishes. Seed cake contains high percentage of proteins (35-44%) and can be used as livestock feed. Because of the high contents of lignin (40-45%) and cellulose (28-40%), tobacco stems can be used for production of energy briquettes, which makes tobacco obtain a new usability value. The aim of the experimental researches presented in this paper is to define the possibilities for production of briquettes from tobacco stems and wood raw material and to evaluate the impact of this kind of raw material on briquettes properties. For this purpose five models were made: O-control model: 100% wood raw material (BW); model T-I - 25% tobacco stems (TS) : 75% BW; model T-II - 50% TS : 50% BW; model T-III - 75% TS : 25% BW and model T-IV - 100% TS. The results of the research show that density of the briquettes is within the limits of 526.61 kg/m3 for model T-IV, to 782.73 kg/m3 for control model-O. The ash content is a little lower than the standard values and it ranges from 0.32% for O-control model, to 2.17% for model T-IV. The sulphur content is much below permissible content (0.08%), and it ranges from 0.003 to 0.008%. These briquettes, according to the low calorific value are classified in II and I class. In the smoke of the burned briquettes, minimal quantity (0.005%) of nicotine is identified

Risk assessment and the implementation of measures for a healthy and safe work before the employee starts working, is the basic principle of the prevention of occupational injuries, occupational diseases and diseases related to work.Bearing that in mind, the goal of this paper is to describe the activities of employers and employees in the field of health, safety and wellbeing of employees in a particular business system as well as to measure progress in safety management by analysing data on occupational injuries, occupational diseases and diseases related to work.The research conducted in this paper is based on information and data collected from the public company "Vojvodinašume" and on the description from literature sources. For the purpose of processing the collected data, we used descriptive statistical methods and the data proper are presented graphically and in tabular form in order to facilitate analysis and comparison.Results of the research showed that the number of occupational injuries in the public company "Vojvodinašume" in the period from 2004 to 2013 reduced, particularly the number of minor injuries. However, the public company "Vojvodinašume", in addition to reducing the number of minor injuries, is obliged to eliminate major and fatal occupational injuries, as well as to enable effective prevention of the occurrence of occupational diseases and diseases related to work.

The aim of this paper was to examine cholesterol content in meat of five Cyprinidae species: white bream (Bllica bjoerkna L), carp bream (Abramis brama L), baltic vimba (Vimba vimba carinata Pallas), zope (Abramis balerus L) and crucian carp (Carassius carassius gibelio Bloch) from the river Danube. Cholesterol content was examined in the function of season factor and individual weight. Cholesterol concentration in meat of white bream carp bream, baltic vimba, zope and crucian carp is on average level below 20 mg/100 g of meat, which makes meat of these fish species nutritively very valuable. Cholesterol content is variable during the season. Its concentration in meat and in lipids is lowest during spring, during summer it increases and during autumn decreases, except in meat of white bream. Body weight has influence on cholesterol content when its concentration is expressed as % of cholesterol in lipids. Its content in lipids decreases with increasing of individual weight, except in meat of carp bream

In very short time big changes occurred in the agrarian structure, the structure of the population, territorial and socio-economical deployment. According to that, there is an obvious discontinuity in the development of rural areas. Pointing out the resources of the region during transformation and rapid development of agriculture, rural development and development of rural regions. The largest part of the development potential based on resource utilization is precisely located in the northern region of Montenegro. The basic method used in this paper is descriptive statistics applied to the collection of relevant data resources of the region, document analysis, comparison and synthesis. The signi icant changes in socio-demographics appeared, an increasing part of the elders and the decreasing of the youth, and decreasing the part of the agricultural population. The main leading factors of the development of agriculture and rural development are the family farms in the region, which is about 26.000 and the resources of land, livestock, and labor. The speci icity of the region is re lected in the changing structure of the agricultural population, socioeconomic , demographic, territorial distribution of the population, and migration. The signi icant differences in the development of agriculture and rural development in the region are also present. Resources are not fully utilized in order to reduce the differences in the development of the region and to accelerate the development of less developed areas. Also, the regional development of the areas is needed for measures and program of balanced development of local self-government.
