The research presented in this work has been directed to achieve an optimal and economic medium, for the protein biosynthesis. The carbon source and the mineral elements are provided by the fresh marc diffusion solution and the source of organic nitrogen and growth factors are provided by proteic wine yeast extract. For the alcoholic fermentation it was used a strain of Saccharomyces ellipsoideus and for obtaining the biomass, a strain of Candida robusta. There were performed two series of experiments in which the alcoholic fermentation progress was monitored as follows: by titration of the carbohydrates, at the beginning and respectively at the end of the fermentation; by determining the optical density of the culture medium and by the determination of alcohol in the fermented solution. Protein biosynthesis was monitored by measurement of the alcohol concentration at the beginning and end of the process, by the determination of the optical density of the culture medium, by the determination of residual sugar, and by determining wet and dry biomass. The wet biomass was used for the protein titration. At the termination of the bioprocess was determined the dry matter in the culture medium.

This paper aims to present an outlook for agriculture in terms of vision Arges farmers. In this paper going to disseminate some of the information obtained through questionnaires, evaluation of data from the survey was conducted the test of association, (Chi, Chi-square, χ2 Hi or theoretically), waste is standardized (R), contingency coefficient C Pearson's correlation coefficient and Cramer's V. The purpose of the questionnaire was to identify farmers' opinion on the landform where the farms surveyed found the following aspect: the ways of upgrading deemed necessary to be implemented on farms in the county Arges. As a result of the survey revealed that farmers consider mechanization as a method of upgrading a 86%, the choice being influenced by the mechanization of farms located where one can find relief, followed by varieties (76%) and crop technologies (72%) as a method of upgrading but their choice is influenced by the relief where it is found located holdings held by respondents, this was observed by using nonparametric correlations.

Very few studies in various countries have been conducted in the context of effect of food health claims onto consumer health and purchase behavior. Health claim messages vary from country to country; but overall consumers view these claims as useful. Generally it is observed that consumers prefer short and concise health claim messages as compared to more long and complex ones. Moreover consumers are of the viewpoint that health claims are more effective if supported and approved by government. Foods with health claims are viewed healthier by consumers, but in some cases consumers may get discouraged by health claims when they are unable to properly comprehend the intended message of nutrition claims. Consumers remain vague between distinguishing health claims, content and structure-function of nutrients. Furthermore there is past evidence that in few instances consumers have improved their dietary choices and knowledge regarding health concern because of use of health claims by manufacturers and governing bodies. This study is a review of contemporary health claim practices in the global upfront.

Corkscrew horns Valachian sheep is a breed from the Early Egyptian (Ovis paleoegiptica) phileic group, located in Serbia, Montenegro, Panonia, and Romanian border with Serbia. The tribe was named by Buffon (1780), Darwin (1865) Valachian, by Serbs Corkscrew Horns Valachian (Valaska vitorogta), by Hungarian Racka (=Serbian), by Linnaeus O.a.strpsiceros. The translation of strepsiceros into German=Zackel (Nathusius 1890), produced a confusion with the Valachian philetic group descending from the Thrakian philetic group. To avoid confusion, we proposed (1994) to use for this philetic group the Serbian name Valachian Corkscrew Horns. It is a sedentary sheep, not adapted to transhumance and large flocks, it does not support wintering in open field, even to stay in the rain. It has a smaller weight of fine fibbers in the mixed wool, it seems that its black colour is recessive, reverse than in Valachia (Tsurcana) breeds. It is economically not competitive with other local and improved breeds and it is in danger of extinction in Serbia and even Romania and well conserved in Hungary. It was considered as a historical document (Dunka 1984) and perhaps it is. It is a proof for the former existence of a Valachian tribe in this area, implicit for the Valachian contribution to the ethno genesis of nations in this region. As an interesting genetic resource, but also for the aesthetic aspect of its horns and for some cultural reasons, it deserves to have a good genetic conservation programme.

The agriculture practiced in Calarasi county has negative effects on soil and water sources. The significant quantities of chemical fertilizers and fito-sanitary products, mono crops practicing, vegetal layer reducing (pasture) and poor organic waste management derived from agriculture vegetal remains and animal manure) lead to soil and ground water pollution. Due to the geographical position of the county, it is needed to monitor constantly the agricultural sector that can flow into the Danube high quantities of nitrites and nitrates. Călăraşi county has a high potential of biomass, enough to obtain natural fertilizers and biogas.

Rural tourism from Western Carpathian Mountain was characterized in the last years by a low occupancy rate and a decline in tourist arrivals, due, beside of the direct effects of economic crises, to the remote location of mountain villages and to the low quality of infrastructure. For this reason we consider that the implementation of complex and integrated products based on tour thematic circuits represents a real opportunity to develop local rural tourism industry. The aim of this paper is to identify which is the best networking solution, based on clustering analysis. The Multidimensional Scaling Method and Hierarchical Cluster Method permitted us to demonstrate and identify the best way of clustering, and, in this way, the best route for a potential tour touristic circuit. Reported to the counties from which the villages take part, the identified cluster concentrate 57.7% of rural touristic accommodations and 65.0% of tourist arrivals, but it has an occupancy rate of only 5.9%. By implementing new complex touristic products we consider that can be assured a rise of this touristic dimension of the cluster and we propose more in depth studies regarding the profile of the potential customers.

The main purpose of this study was to investigate the main barriers to development of organic farming system in Kermanshah Province, Iran. Statistical population in this study consisted of all farmers in Kermanshah province, Iran. Applying stratified random sampling method, 137 farmers were selected as a sample. The main instrument in this study was questionnaire which its validity was confirmed by the panel of experts and its reliability was established by Cronbach's Alpha coefficient. Data was analyzed by SPSSWin16 software. Principal component analysis was used as main statistical technique to analyze the data. The results of factor analysis revealed that 4 factors including “Infrastructural”, “technical-managerial”, “economic-financial” and “educational” explained 42.36 percent of the variance. Results of this study have applications for agriculture development policy- makers for development of organic farming in Iran.
