Air-dried stem bark of UapacatogoensisPax (Phyllanthaceae, a segregate of Euphorbiaceaesensulato) was powdered and successively extracted using the three selective solvents;n-hexane, ethyl acetate and methanol by Soxhlet extraction. The n-hexane extracted 0.44%, ethyl acetate extracted 0.85% and methanol extracted 17.63% of the plant material. Preliminary phytochemical screening of the extracts revealed that U.togoensis stem bark contains carbohydrates, glycosides, cardiac glycosides, saponins, tannins, flavonoids, alkaloids, steroids and triterpenes. Antimicrobial activities studies showed that all the extracts are active against the same set of bacteria and fungi. The extracts have activity against MRSA,S,aureus, C. ulcerans, E. coli, S. typhi, S. dyseateriae,P. mirabilis, N. gonorrhoae, C. albicans, C. krusei and C. tropicalis but have no activity against VRE, S. pyogenes, P. aeruginosa and C.stellatoidea. Thus, the U. togoensis stem bark extract is both antibacterial and antifungal. The MIC of the extracts are generally lower than the MBC/MFC. In most cases, the MIC of the extracts is 10mg/mL and the MBC/MFC is 20mg/mL

In this paper a mathematical approach has been studied to ascertain the cyber crime which is a worsening problem that can lead to loss of financial and personal information. However, e-crime is particularly hard to detect since internet is boundless that make evidence hard to collect. We have developed a probabilistic model using Poisson Process to determine the number of infected computers for a period of times when an individual becomes infected by the virus. A qualitatively distinct potential scenario is predicted to fight the cyber-crime. It is believed that the outcomes obtained from the present investigation will provide useful information for application and also serve as a complement to the previous investigations.

The purpose of this paper is to present the findings of a research on Why a Community Tolerate Dust Pollution and Noise Disturbance? A Study of Corporate Social Responsibility in Nickel Mining The study was conducted in the village of Motui, Sub-District of Motui, District of North Konawe, Indonesia. Eighty samples were randomly selected using Slovin's formula from 352 population affected by the mining operation. The research methodology applied a descriptive analysis. The measurement of study variables used Likert scale (Riduwan, 2003), namely: strongly agree (score 5), agree (score 4), neutral (score 3), disagree (score 2), and strongly disagree (score 1). In valuing empirically the research variables, this study adopted the valuing principle of Arikunto (1998). An in-depth analysis was conducted using interviews, discussions and observations to validate the response of respondents. The findings showed that 1) based on the total average of the perception of the members of the community, mining operation is categorized as average or neutral (2.75). It means the presence of the mining company and its operation did not significantly disturb the surrounding community. In addition, based on personal communication through interviews, monetary compensation mitigated their intolerance to the noise disturbance and dust pollution. 2) With regard to the CSR of the mining companies, the survey indicated community members are strongly dependent on the on decisions of mining companies and the local government. It means they are passive recipients and beneficiaries. These two items showed the weak bargaining position of community towards their fate. It is evident that their need for cash money is more much preferred in exchange for expressing and demanding for their rights. In summary, the perception and attitude of the respondents showed a high average score of 3.99 in terms of community participation in CSR of the mining companies.

This paper presents an integration of a series of sequential and parallel computations for vehicle number plate segmentation from vehicle image based on watershed and visualization techniques. The work is modeled into five stages. In the first stage a sequential computation is performed to make an initial segmentation through computing gradient magnitude, applying watershed transformation and reconstruction of image using morphological operations. In the second stage regional maxima and watershed ridge lines are obtained in parallel. The third stage performs sequential computation from the outputs of the second stage by applying watershed transformation to obtain markers and objects in image. The fourth stage extracts required features and identify probable candidate regions in parallel. The fifth stage takes the outputs of the fourth stage and segments the number plate from the image using visualization technique. The result of the proposed model is compared with the results obtained from the sequential model for analysis. The experimental results show computational performance is relatively 1.6 times faster than the sequential model on similar machines.
