Food Crop Diversification and Production Efficiency: Insights from Parametric Estimations in Southern District of Ondo State
David Awolala and Igbekele Ajibefun
Increasing pressures on arable cropland and rapidly diminishing traditional fallow period are the ultimate challenges to minimize risks faced by small farmers as they attempt to improve their productivity and efficient in resource use in the tropics. This study investigated the influence of extent of crop diversification on technical efficiency among small scale farmers in the southern district of Ondo State, Nigeria. Household data collected on the arable farmers were analyzed using entropy diversification index, stochastic frontier production function and maximum-likelihood estimation. Results found that highly diversified farmers were more technically efficient than those in low diversification. The technical efficiency of farmers in low diversification group ranges between 14% and 85%. The technical efficiency of highly diversified farmers ranges between 23% and 95%, with a mean of 68%. Maximum-likelihood estimates result shows that low diversified famers recorded returns-to-scale of 1.15 compared with highly diversified farmers of 1.18. The two groups of farmers used production inputs within the rational zone of production space, yet they were still operating at sub-optimal levels. Farmers’ age and farming experience were inversely related to extent of crop diversification while education and family size positively influenced the extent of diversification.

Applications of SNP Markers for Genotyping of Plant Pathogenic Microorganisms.
Setti Benali, Bencheikh Mohamed and Henni Jamel Eddine
Single nucleotide polymorphisms (SNP) has recently become a new marker of interest to plant pathologist because of their abundance, high density within the genome, their low rate mutation as well as the advances technologies with which SNPs are discovered. Increasing high throughput technologies have been developed recently for optimal and efficient discovery of SNPs like the matrix assisted laser desorption ionization – time of flight (MALDI-TOF), the pyrosequencing, the method involving 5’exonuclease assay such as TaqMan, Single Strand Confirmation, Allele specific hybridation (ASH). The choice of one among these technologies depends on the objective of the research and the availability of laboratory equipments. On the other hand, a computational approach to SNP mining is becoming more popular with the increasing of the freely databases as well as the number of bioinformatics pipelines such as software, and packages modules developed for interrogating, detecting, retrieving SNPs automatically. This great popularity of the computational method has led to the construction of huge numbers of SNP databases for both prokaryotes and eukaryotes organisms including phytopathogenic microorganisms. SNP markers have proved to be useful in studies such as population genetic diversity, population structure and differentiation, diagnostics and strain fingerprinting, associations and genetic mapping studies. The purpose of this review is to present the most relevant published reports with emphasis on the use of the SNP markers in plant pathology. Among the aspects reviewed in this paper includes Distribution, abundance and variability of SNPs, the main method used for discovery and the detection of SNPs and the in silico mining through the publicly databases. Thereafter, we present the various applications of SNP markers in molecular plant pathology.

Synthesis, Characterization, Kinetics and Reaction Mechanism of the Zinc (Ii) Complexes of Barbtturic Acid
Oladipo M. A, Adekunle F.A.O and Bello I.A
Three complexes of barbituric acid with zinc (II) were synthesized and isolated. The compounds were characterized by microanalysis, infrared spectra and magnetic susceptibility measurements. The infrared spectra showed that the frequencies of the asymmetric C=O, C=C stretching vibrations were lowered from their ligand values indicating complexation. The electronic spectra data have been interpreted in terms of the p3-p4 and d-d transitions. The room temperature magnetic moments suggest diamagnetic complexes. The kinetic data are consistent with a mechanism which follows a rapid pre-equilibrium in which the rate is independent of the metal concentration, suggesting an interchange associative mechanism.

Sustaining IT PMOs during Cycles of Global Recession
Parvez Mahmood Khan, M M Sufyan Beg and Musheer Ahmad
Growth in the number of PMOs established by the industry over last decade and ever growing body of literature on PMO related research in academia is a clear indication that there is very clear interest of researchers, practitioners and industries across the globe to understand and explore value propositions of PMO. However, there is still a lack of consensus on many critical aspects of PMOs. While there are many PMOs being established, but there are also many being closed and disbanded, which is definitely a matter of concern. In industry environment, a narrow majority of PMOs are well-regarded by their organizations and are seen as contributing business value, many of the others “are still struggling to show value for money and some are failing, causing a high mortality rate among PMOs”.
This paper is the result of a study undertaken to get a deeper understanding of factors that may be causing mortality and failure of PMOs. Post Implementation Reviews of 4-failed & 3-challenged PMOs in IT-Industry were carried out with concerned Project Managers & PMO-staff, using grounded theory research method, with support from the concerned enterprise from IT-Industry.

Not Happy Moving Back to Homeland? Why People Re-Migrate to Foreign Countries?
Brain drain and reverse brain drain is a key phenomenon in human migration. However, re-migration has now become a contemporary field of research where people move back to foreign lands. This study tries to find the push and pull factors involved in re-migration. ‘Foreign Faculty Hiring Program’ a project initiated by Higher Education Commission of Pakistan tried to bring highly qualified people back to Pakistan. The faculty that returned through this program has been surveyed to find factors that forced people to move back to foreign countries. A total of 149 observations were recorded. It has been found that Unemployment in home country (push) and better environment in foreign countries to raise children (pull) are major factors in re-migration. Difficulty to settle in home country and better opportunities abroad were also observed as factors involved in re-migration. Interview was also conducted to find reasons for people leaving the program. It was found that they left because they were unhappy with their jobs. Some left because they found better jobs in other local or international universities. However, it was also found that some faculty members came on sabbatical leave and left because they thought their job was only for a year.

Image Compression using Improved Wavelet Shrinkage and Artificial Neural Network
Seyed Mahmoud Anisheh and Davud Asemani
This paper presents a novel approach for image compression using improved wavelet shrinkage method in combination with artificial neural networks. In the proposed method, a new method for choosing threshold value is presented for wavelet shrinkage. It is proposed to select the threshold value considering two parameters including mean square error (MSE) which is utilized to evaluate the image compression quality and compression ratio (CR). A cost function is also proposed in terms of the mentioned parameters. Then, it is minimized using Cuckoo optimization algorithm. In the second step, an artificial neural network is used as encoder. Performance of proposed method is evaluated using peak signal to noise ratio (PSNR) criterion. The experimental results demonstrate the superiority of the proposed technique for image compression compared to earlier works

Seyedahmad Hossieni, Reza Malihi and Hushang Rushanmehr
Background: of Migraine is a headache that occurs due to abnormal vascular phenomena. At least 40% of people will suffer. One of the factors that trigger headaches in patients with migraine is food ingredients. Purpose this study was to compare the dietary pattern of patients with migraines and healthy individuals.
Methods: This case - control study of 40 patients referred to a hospital clinic in Golestan migraine patients and 40 healthy controls were considered. Data were collected using interview from both groups. Inventory number (1) including age, sex, weight and some general questions. Questionnaire (2) food frequency questionnaire (FFQ) to assess the food consumption pattern based on daily, weekly and monthly. Questionnaire number (3) only the group was completed by including a list of foods suspected to exacerbate or mitigate disease.
Result: Based on the result of the food frequency questionnaire (FFQ) between daily and weekly food consumption in both cases and control wasn’t significant. While the results from the questionnaire number (3) that the results was completed by patients showed that sausages, salami and onion 47%, cheeses and beverages 40%, garlic 37% saturated, 35% cocoa, chocolate and fatty foods in 25% and 27% from Chaclate trigger migraine attacks. Also the food extenuating cited by patients can be tea and coffee (roughly "half of the patients), dates (37% of patients), carrot juice (in 25%), fruits and sweets (roughly" in 20 percent), and fruits, including grapes, apricots, cherries, apples and pears (on average 19% of patients) include Food frequency comparisons between two groups showed that daily consumption of ice cream, hot dogs, chocolate ,sausage and salami taking us a significant difference (05/0> P)..
CONCLUSIONS: These results coincide with previous studies on the impact of food such as Sausage, salami, cheese, similar cocoa and fatty foods increase the intensity of migraine attacks. But the impact of the attacks can be reduced food intake due to their effect on blood glucose level.
