Coordination compounds of n-phthaloylglycine and n-phthaloyltyrosine and their antimicrobial activities
Coordination compounds derived from N-phthaloylglycine and N-phthaloyltyrosine were synthesized. The ligands were formed by 1:2 molar condensation of phthalic anhydride with tyrosine and glycine respectively. The complexes were formulated as [Zn(PHG)2 (H2O)2] (OAc)2[1], [Ni(PHG)2 (H2O)2] (OAc)2 [2] and [Cu(PHT)2 ] (OAc)2 [3] characterized by melting point, conductivity, AAS , IR, Uv-Visible spectroscopies. Both ligands were found to be bidentate. For complexes [1] and [2] the metal ions coordinate through both oxygen of OH and C=O in the carboxylic group to give octahedral geometry whereas in the [3] the coordination of metal ion occurs through both oxygen of phenoxyl and carbonyl group resulting in tetrahedral geometry. The antimicrobial studies using four test organisms(P.aerugenosa, E.Coli, S. aureus and C. albicans) revealed that the metal complexes exhibit higher activity than their respective ligands.

Determination of appropriate time for farm tractors replacement based on economic analysis
Nowadays, tractor is one of the most important power sources in agriculture. Replacement of tractor is one of the most important decisions that should be made by farmer. Proper performance in this case can lead to timely, high quality farm operations which in turns results in considerable decrease in product expenditures and also more income. The current study was performed in order to determine economically optimum life of MF285 tractors in Debal Khazaei Agro-Industry Co. in Khuzestan province of Iran. Moreover, listed price of tractor, annual depreciation and Internal Rate of Return in the study period were calculated. Then, these items accompanied by their repair and maintenance cost were used to determine their economic life. Finally, replacement time for the study tractors was obtained equal as 6981 hours. These hours of operation are performed in about 14 years and thus the tractor should be replaced.

Directed edge - graceful labeling of trees
Rosa [13] introduced the notion of graceful labelings. The concept of magic, antimagic and conservative labelings have been extended to directed graphs [11]. Bloom and Hsu [3, 4, 5] extended the notion of graceful labeling to directed graphs. In 1985, Lo [12] introduced the notion of edge – graceful graphs. We introduced [8] the concept of edge – graceful labelings to directed graphs and further studied in [9]. In this paper we investigate directed edge – graceful labeling of trees.

Distributive justice in context of traditional knowledge holders
Any straightjacket formula, for a distributive justice in any given community or system is difficult to be evolved. And when the question is of international community, the task goes even more difficult, or at times nearly impossible. Any system to be fair and just has to work with the notion of ‘universal equalities with fair distribution of resources’ immaterial of the birth and power of the people in the society. But the inequalities between the developed and developing nations have given rise to different facets of distributive justice. When one talks about the problem of profit sharing of the Indigenous communities as to their Tradition Knowledge, this sounds to be an economic issue. But the reality is that it engulfs various social, cultural and political concerns of the distribution of ‘materials’.To convert the traditional knowledge and cultural heritage of the indigenous people into definitions of patents, copyrights, trademarks, personality, and trade secrets is to ignore that traditional knowledge and cultural heritage that identify an indigenous people and makes a mockery of their struggle for freedom and self-determination. Their struggle for self-determination has the symbiotic benefits of maintaining cultural cohesion and the protection of the greater public welfare. So the paper concentrates upon the distribution of honours and materials in a justified manner especially in context of indigenous people.

Duplicate of domestic behavior in Iran’s foreign policy arena during Khatami presidency
Ethnic conflict is a worldwide issue that has challenged many countries since the second half of the twentieth century in particular. As multi-ethnic country Iran, which is positioned at the center of an ethnic conflict area namely the Middle East, has experienced many ethnic conflicts since the formation of the modern nation state in 1906, and especially after Iran’s Islamic revolution in 1979. The main ethnic groups involved in these conflicts are Kurds, Turkmen, Arabs, Baluchs and Azeries. Since the Revolution, Iran had attempted to quarrel the ethnic conflict severely. When Khatami took power, however, he behaved peacefully towards minorities and ethnic tensions eased. Based on the theory that states duplicate their domestic patterns of behavior in their inter-state relations, the paper intends to examine this theory in the case of Iran during Khatami’s administration. The article concludes that when Khatami came to office, he attempted to deal with the ethnic groups on the basis of democratic values. He extended these values to Iran’s foreign policy arena which led to an improvement in relations between Iran and other countries. In other words, he could replicate internal peaceful policy in Iran’s inter-state relations and he made a direct connection between these two spheres.

Economic Analysis of tomato production in Nigeria (1981-2017)
Improving tomato production is one of the important greatest challenges facing Nigeria government today. Since tomato is an important fruit crop for the country and for individual households, it has important implications for livelihood of rural people. In order to achieve this, several interventions in the sector were done in an attempt to improve production. The study analyzes the tomato production from year 1981-2017. The study was carried out to examine the trend in tomato production and importation, the determinant of tomato production and the effect of tomato import on it producer in Nigeria. Secondary data obtained from Central Bank of Nigeria Statistics and Food and Agricultural Organization were used for the study. Dickey-Fuller unit root test and Co-integration test were employed to analyze the data collected. The result showed that the time series used for the study are all stationary at first difference. The result of co-integration test in the short-run Error Correction Model (ECM) estimation at 1 lag length shows that Agricultural labour, local tomato price and rainfall are significant to tomato production. The result of the long-run ECM estimation shows that Agricultural labour, local tomato price and rainfall are significant to tomato production. The result of the trend local tomato price showed it was stationary at first difference and also positively significant to tomato production at both short-run and long-run ECM estimation which indicates that local tomato price time trend has being favourable for tomato production. Result of the trend of agriculture labour showed that it was stationary at first difference and positively significant in the short-run and positively in the long-run ECM estimation to tomato production which indicates that agricultural labour time trend is inversely related to tomato production. All this can be due to the country not depending on importation of agricultural produce, food production through agriculture to the masses by the government within the country, implying that the government support production and more exportation resulting in an government increasing revenue. It is therefore concluded that more agricultural produce should be produce in the country to control importation.
