Motivation and Entrepreneurial Characteristics of Sustainable Immigrant-owned Businesses in the US
In the United States, foreign-born individuals are more than twice as likely to start new ventures, immigrant-owned businesses, however, fail within the first 5 years. The purpose of this single case study was to explore the strategies U.S.-based Togolese small business owners who were engaged in entrepreneurial activities in Togo. The Schumpeterian entrepreneurship theory underpinned the study and served as a theoretical reference. Interview data were collected from 20 successful Togolese small business owners who resided in the Washington D.C. metropolitan area, who were engaged in entrepreneurial activities in Togo, and who had been in business for more than 5 years. Data analysis involved using coding techniques and word clustering, and qualitative data analytical software. The use of methodological triangulation enabled deeper analysis and added to the rigor of the study. The key themes emerging from the coding and thematic analysis of interviews included motivation and entrepreneurial characteristics such as risk propensity, entrepreneurial education, leadership, self-confidence, and vision. The findings of the study may improve the social and business success of immigrant business owners, and entrepreneurs may use the knowledge to improve business success, which could lead to the creation of jobs and improvement in the standard of living of U.S.-based Togolese entrepreneurs. The discoveries from the research may also contribute for the welfare of local communities in Togo, as the diaspora flow of investments and remittances from the United States may increase.

Optimal substation placement and feeder routing in distribution system planning using genetic algorithm
In this paper, an attempt has been made to develop a new algorithm for distribution system planning. The proposed algorithm does not require prior knowledge of candidate substation location and can obtain the “number, location and service area” of HV/MV substations, the optimal feeder configuration and the optimal sizes of branch conductors while satisfying constraints such as current capacity, voltage drop and heuristic rules. Several algorithms are proposed for distribution systems planning. A comprehensive algorithm is developed for obtaining the optimal “number, location and service area” of substation using GA and a generalized algorithm is modified to optimal feeder path on minimum loss criterion. Direct approach load flow is used for solving radial distribution networks and branch conductor optimization algorithm. The load flow algorithm and branch conductor optimization techniques are used as subroutine in the generalized distribution systems planning algorithm. Through numerical example the validity of proposed method is verified.

Ordinal logistic model for finding the risk factors of HIV testing in injecting drug users
The ordinal regression is a method that is used to robust the model when dependent variable is ordinal and Independent variables may be dichotomous, polytomous, and continuous or combination of these. Ordinal logistic regression is used to predict the “odds” of having a lower or a higher value for dependent variable (y), based on independent variable (x). In practice, the frequently used type of model is a proportional odds model in ordinal logistic regression. HIV testing is necessary for preventing and reducing the HIV transmission. However, there are various Socio-demographic and HIV related behavior factors contribute the high or low HIV testing in general population and high risk groups. Intend of this study find out the important factors of the HIV testing in Injecting drug users (IDUs) patients. The ordinal logistic regression model makes assumptions about the nature of the relationship between the order response variable HIV testing Methods: Total 139 IDUs patients’ collect the information for this research based on specific questioner from the district Kamur in Bihar. In study, Ordinal logistic regression analysis to determine the factors which are considered to be a significant contributor in HIV testing. The ordinal logistic regression model was used to build models for dependent variable HIV testing and independent variables which are Age, Marital Status, Education, Occupation, Stigma, Income, STI/STD problems, Needle injecting sharing and HIV information. Results: In this research apply the proportional odds model for confirm the applicability of the ordinal logistic model. We determine the all parameter the significant of the model. We found that Needle sharing, Abscess problem, Abuse, Heard about STI, HIV, Income, HIV knowledge, HIV transmission through multiple partners shows significant contribution to IDUs patient for HIV testing. Conclusion: This study has made an attempt to recognize the predictors of HIV testing for injecting drug users by developing an ordinal logistic regression model.

Pectin based ZnO Nanocomposite Hydrogel: Evaluation as Adsorbent for Divalent Metal Ions from Aqueous Solutions
Synthesis of a nanocomposite hydrogel P-PAMPS-PAAm/ZnO, has been made by the polymerization of 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) and acrylamide (AAm) in the presence of pectin (P) and zinc oxide (ZnO) using microwave irradiation technique. FTIR, XRD, SEM and TEM studies indicated the formation of a gel network and incorporation of ZnO particles within gel structure. The system was evaluated for adsorption of Cu (II) and Pb(II) ions from aqueous solutions. About 77 mgg-1 of Cu(II) and 125 mgg-1 of Pb(II) could be adsorbed from aqueous solutions. Different isotherm models have been employed to study the adsorption process and the data is found to fit well with Langmuir isotherm model. The kinetic studies revealed a second-order adsorption process. About 95% of the metal ions adsorbed could be stripped in acidic medium of pH 1.2 indicating the reusability of the gel.

Phorbol-12-myristate-13-acetate degradation in defatted jatropha curcas seed meal through solid state fermentation
The study aimed at detoxifying JCSM using biological treatments (spontaneously, fungi cocktail and specific). Shimadzu HPLC/ UV was used to quantify phorbol esters in Jatropha curcas seed meal under isocratic conditions. After six days of fermentation, cocktail of fungi, and spontaneous fermentation of JCSM was effective in reducing PE concentration. Defattening seed meal using cold maceration in petroleum ether reduced phorbol-12-myristate-13-acetate (PMA) in the JCSM from 40.42 to 10.9 ng/ml prior to solid state fermentation. Spontaneous fermentation of defatted JCSM further reduced PMA from 10.9 to 5.05 ng/ml (53.6%). Fungi isolated during spontaneous fermentation included, Aspergillus niger (B), Aspergillus flavus (A), Rhizopus Stolonifer (C), Penicillium chrysogenum (D) and Fusarium species. The reduction of PE ranged between 10.71 – 1.46 ng/ml when single or a combination of the fungi isolates were used in solid state fermentation of the defatted seed meal. P. chrysogenum reduced phorbol ester levels (PE) in defatted seed 76.5%, R. stolonifer 43.3%, A. flavus 35.6% and A. niger 1.72%. When fungi isolates were paired, A. niger + P. chrysogenum (BD) reduced PE levels by 13.7%, A. flavus + A. niger 64.5%, A. flavus + P. chrysogenum 70.3%, A. flavus + R. stolonifer 78.8%, A. niger + R. stolonifer 86.6% and R. stolonifer + P. chrysogenum 86.6%. The treatment combination of A. niger + R. stolonifer + P. chrysogenum reduced PE levels by 84.0%, A. flavus + A. niger + R. stolonifer to 67.2% and A. flavus + R. stolonifer + P. chrysogenum to 62.3%. P. chrysogenum was effective as a single isolate but its activity was suppressed when paired with A. niger. Treatments of the deffated seed with, A. flavus + R. stolonifer; A. niger + R. stolonifer; R. stolonifer + P. chrysogenum; and A. niger + R. stolonifer + P. chrysogenum were the only combination that exceeded the phorbol reductive activity of P. chrysogenum in. It could therefore be concluded that Jatropha curcas seed meals can be detoxified by solid state fermentation.
