The study analyzed the factors influencing cassava value addition by rural agribusiness entrepreneurs in Abia state, Nigeria. The specific objectives were to: ascertain the various forms of the value added cassava products produced by the respondents; estimate the factors that influence farmers’ decision to add value to cassava; and make recommendations based on the findings. A multi-stage random sampling technique was used to select 70 respondents. Primary data were collected through the aid of a well structured questionnaire. Data collected were analyzed using descriptive statistical tools such as frequency, mean, tables, percentage as well as the binary logit model. The result of the binary logistic results indicated that the coefficients of gender, education, income, household size and output were statistically significant at different levels of probability. The study therefore recommended that encouragement should be given to females to go into cassava value addition as well as making high yielding varieties available to the entrepreneurs by the government and its agencies whose mandate is to do so.

For the isolation of the genomic deoxyribonucleic acid (DNA) from vine leaves of distant hybrids (Vitis vinifera L. x Muscadinia rotundifolia Michx.), the DNA isolation protocol based on CTAB method was used. The grouping of distant hybrids in the obtained dendrogram shows that at the DNA level there are some differences between them, differences sometimes unnoticeable at the level of ampelographic characterization. As a result, in the characterization of varieties and hybrids of vines, the ampelographic analysis needs to be supplemented by an analysis at the molecular level, based on DNA amplification techniques. As a result of distant hybrids grouping based on the size of alleles, it was found that there are two distinct main groups denoted by A and B, each having secondary branches. The hybrid F4 BC3 DRX-M4-541 1 is closely akin to the variety Chasellas dóre. Also, the two samples of Vitis vylvestris Gmel. have been found to be genetically different, being placed in different subgroups. The hybrid F4 BC3 DRX-M4-536 is genetically close to the male specimen of Vitis sylvestris Gmel. The distant hybrid DRX-M4-660, which proved to have larger differences at the molecular level, isn’t grouped in a cluster with any other hybrid.

The ingestion of high levels of heavy metals through drinking water intake can lead to chronic diseases such as renal failure, liver cirrhosis and chronic anemia. The present study evaluates the lead content in thirteen private wells from four rural areas located in Baia Mare (NW Romania) metropolitan area. Based on the lead concentration, the daily intake rate of Pb was calculated for the female, male and children who use these water sources as drinking water supplies. The daily ingestion rate of lead due to water consumption was considerably higher for the inhabitants from Tăuţii de Sus (0.05 – 0.21 μg/day/person) than for the inhabitants from the other villages (<0.08 μg/day/person).

Movement "raw food" is not an invention of the XXI century, not even of the twentieth century. The first studies occurred in the late nineteenth century, but the development of the movement happened only after ending of the Second World War. The name „row-vegan” was given by the great German physician Ernest Gunter who speaks and describes the many advantages of this harmonious way of life, about this natural diet in his book “raw-vegan – a hope for everyone". We must not confuse the natural or vegetarian style with this diet. Live-Food can change people's lives by improving health, physical and mental work capacity, by reducing expenses on medicines, doctors, hospitals, the disease risk transmitted by animals: trichinosis, tuberculosis, avian flu, swine flu, foot and mouth disease, and releasing "slavery cooking" of a huge number of people, especially women"

The paper aims to present the evolution of main sectoral indicators of Romania’s agriculture in the context of European Union enlarged to 27 countries. There have been analysed the sizes and trends of the basic agricultural resources including land, livestock and labour force, as well as the synthetic indicators related to the output. The research was based on the statistical data provided by Eurostat. The results emphasize that Romania ranks among the forefront states regarding the utilized agricultural area, as well as having the largest number of employees in the primary sector. The share of Romania’s primary sector in the gross value added, although four time greater than the EU average, had a downward trend, recording a minimum of 6.4% in 2013. Romania’s agricultural trade balance gathered a deficit of -8 billion Euros in the post-accession period; however, a net export performance was merely achieved in 2013. In conclusion, Romania’s agricultural labour productivity was placed in a modest position by the gaps comparing to the majority of member states, that drew attention to the necessary improvements of the performances and to narrowing the disparities.

In this paper, the procedures were estimated to improve the reproducibility and selectivity of the method and determine the influence of different analytical parameters (pH, electrolyte composition, deposition time and potential, this ligands). Detection limit of copper in samples of white wine and red Blaj (Romania) was 2-4 ppm, reflecting a deviation of 1.5-2,0%. The results mentioned in this paper were compared with the results obtained using the classical method of atomic adsorption. The sensitivity of the method is twice smaller than the detection of Pb2- ions.

Since its independence, the Republic of Moldova decided to consolidate its place among the democratic nations and started the economic reform in order to integrate it in the European and international economy as well as in the process of globalization. The reform of the national economy was oriented towards the substitution of the old, outdated and almost collapsed socio-economic system by one capable to ensure the continue progress in the society. This reform could be done through fiscal legitimacy, which may be achieved by a clear and transparent establishment and predictable rules, especially in the statutory and the administrative aspects of the tax system. Unfortunatelly, the concept adopted to be implemneted does not consider the ongoing changes and local particularities. After 20 years of implementation, the tax system is still characterized by oversize, austerity and the state's inability to manage its resources efficiently. Nevertheless, many steps have been made to change things in the last 5 years. This paper aimed to examine the tax reform changes in order to reveal the weaknesses of the Moldovan tax system and to understand its areas of strength.

Development of culture of the vine during of his evolution has multiple known methods to improve, such as the natural selection or directed (intraspecific, interspecific, clonal, genetic engineering, etc.). A desideratum of the wine world science and practice remains to be the getting of vines varieties for quality, absolutely resistant to attack by phylloxera (root and leaf). The process of obtaining distant hybrids, just like any cross varieties of Vitis vinifera L. with representatives from the donor species of qualities necessary (resistance to diseases and pests winter low temperatures etc.) can bring to the changing spectrum of chemical compounds and biochemical responsible for the aroma, color and taste of berries, juice and wine obtained. According to the European Union requirements in the production of the wine products, chemical composition of the raw material must meet certain strict requirements. Therefore, the current remain the problem of obtaining new varieties of vines agro-biological characters that meet the maximum requirements for table grapes using fresh consumption and for industrial processing to those intended (juices, concentrates, wines, spirits ).

In this paper, it was researched the biological and ecological orchard apple worm in the Sibiel Village, Sibiu County in terms of 2014 year. Given the increasing damage caused in recent years by the worm Cydia pomonella of apples in the orchard studied, two methods were used: through mass capture of adults with sexual attractant pheromone traps and stage of the study included minimum threshold temperature tracking the insect and by this, calculate the approximate insect biology and ecology on the average daily temperature, precipitation and humidity, for the application of effective treatments consistent with environmental protection is therefore necessary detailed knowledge of the biology of this insect for forecasting and warning treatments. As a conclusion, the use of pheromone traps proved the following advantages: reducing the pest population within the economic threshold, reducing the amount of insecticides for crop protection in some cases even their exclusion, environmental protection and getting ecologically clean agricultural production, keeping useful entomofauna.
