Abstract
In this study we assessed the chemical composition, antioxidant and antibacterial activities of Lavender essential oil. The antioxidant and antibacterial capacity of test sample was assayed by a linoleic acid system and conventional method of bacterial growth inhibition. The results demonstrated that the essential oil consisted of 1,5-Dimethyl-1-vinyl-4-hexenyl but yrate as the most abundant component (43.73%), followed by 1,3,7-Octatriene, 3,7-dimethyl- (25.10%), Eucalyptol (7.32%), and Camphor (3.79%). Lavender essential oil display the stronger antioxidant activity against lipid peroxidation in a linoleic acid model system and good antibacterial activity against four rhinitis-related bacteria including staphylococcus aureus, Micrococcus ascoformans, Proteus vulgaris and Escherichia coli.
Key words: Antibacterial, Lavender; antioxidant, essential oil, extraction, rhinitis.

Abstract
In this experiment, we have used the soil profile as a biological filter that can to absorb pollution and microbes in the domestic wastewater at Iran during 2009. In this experiment, we had 15 lysimeters, that were planted canola (Brassica napus L.) in 1 to 5 lysimeters and were irrigated by domestic wastewater with BOD5 about 150 mg/lit and primary drainage water were accumulated. In the 6 to 9 lysimeters was planted alfalfa (Medicago sativa L.) and were irrigated by primary drainage water and then, were accumulated secondary drainage water. We have irrigation 10, 11 and 12 lysimeters by secondary drainage water that was planted inside the basil (Ocimum basilicum L.). In order to compare plants characteristics, in 13, 14 and 15 lysimeters were planted canola, alfalfa and basil respectively and were irrigated by agronomical water. The results showed that the soil could reduce BOD5 and COD from 150 and 232 mg/lit to 11 and 18 mg/lit respectively in secondary drainage water. The essential oil yield of basil 17% increased under irrigation by secondary drainage water into irrigation by agronomical water. Therefore, the use of secondary drainage water can be increase the quantity and quality yields in plants and the other hand, protects sweet water resources.
Key words: Domestic wastewater, agronomical water, essential oil yield, basil.

Accepted 20 January, 2014
Abstract
The antibiotic produced by a newly isolated Bacillus subtilis has potent anti-tubercular activity against sixteen strains of Mycobacterium tuberculosis, most of which belong to MDR strains. MICs for the sixteen strains were evaluated. A series of spectrum analysis and element analysis determined that the antibiotic’s molecular formula was C27H46O2.
Key words: Bacillus subtilis, antibiotic, MIC, serum, anti-tubercular.

Abstract
Using the convergence theory inspired by models of endogenous growth, this paper analysed convergence in the economies of the Franc Zone countries in Africa. With an econometric validation based on cross-sectional and panel data, the paper tested a number of hypotheses, the main ones being the convergence of the economies of the UEMOA and CEMAC zones through per capita income, the existence of spillover effects, as well as the search for a common growth path for the economies of the two zones. The study’s findings show that the convergence process, and hence that of integration has not been carried out uniformly in the Franc Zone: the process has been given greater emphasis in UEMOA than in CEMAC. Further, the conditional convergence model highlights the existence of key variables that help to maximize the convergence speed. A more refined convergence approach, which used similarities related to production factors and those related to natural advantages highlight the presence of a convergence club. The study found a period-related convergence in the cotton-producing countries, coffee-producing countries and coastal countries. This shows that the hypothesis of a common convergence path in the Franc Zone has not been borne out by our study.
Key words: Beta convergence, stochastic convergence, panel data, cointegration, economic integration.

The dynamic relationship among poverty, inequality, and growth in rural Ethiopia: A micro evidence

Abstract
The Ethiopian government has boldly set very rapid and sustainable growth and its equitable distribution as its prime development objective to end poverty in the foreseeable future. For this reason, promoting agricultural and rural development has been purported by the government as its top development agenda since it took power some 19 years back. Yet the extent to which the government realizes this objective remains in doubt. This paper attempts to analyze the dynamic relationships among poverty, inequality and growth. While many of the available studies use aggregate cross-country data sets, this study, however, uses household panel data-set. The decomposition result indicates that the observed growth was neither rapid nor sustainable. Poverty and inequality have not also declined considerably except between 1995 and 1997. The study also systematically generated 90 observations of indices from the five rounds to estimate Fixed Effect (FE) regression model. The estimated growth and inequality elasticities of poverty were found equal to 3.32 and -3.68, respectively. What this means is that poverty could still remain high if the country fails to achieve rapid and sustainable growth, on the one hand, and simultaneously reduce inequality, on the other.
Key words: Inequality, poverty, growth, fixed effects.

Abstract
The aim of this study was to measure the impact of liberalisation on the South African agricultural economy, particularly the impact on trade flow of the exchange rate, trade liberalisation and distance of trading partners using the gravity model. The model found that all variables were significant at one percent and carried the expected sign. Only the EU dummy variable had an inverse relationship, implying that the EU trade agreement has a negative impact on the export capacity of the South African farmers. This result has important policy implications for the South African agricultural sector in selecting and strengthens the regional block agreement. Given the importance of distance to markets, South Africa should emphasise efforts to reduce transaction costs. It is also important to protect and advocate productivity growth within the era of globalisation challenges Secondly, from an export promotion standpoint, distance in the model result showed that per capita income in importing countries is elastic and significant when it comes to determining exports. Therefore, it is important for South Africa to revise all the existing trade links and extend further to countries or regions with a high per capita income in order to realise export potential.
Key words: Trade liberalisation, distance of trading partners, gravity model.
