If the Business Model is a central concept in traditional entrepreneurship research, it constitutes also an emergent concept and a subject of many pioneer investigations in the context of social entrepreneurship. Indeed, assuring a sufficient and sustainable financing of social activities is one of the most critical issues facing the social entrepreneurship. This paper introduces the concept of Social Business Model and present its specificities compared to the Traditional Business Model. By transposing the traditional business model literature, we will present a framework able to apprehend the specificity of social activities.

The contemporary Nigeria society has been a theatre of unending insurgency from the Fulani herdsmen. The spate of violent attacks from these insurgents against farmers in various part of the country has become a thing of great worry to all. This is moreso as the federal government appears unwilling to bring to book those behind the increasing deadly menace. This paper will therefore seek to examine the socio-ethical religious implications of the above insurgency with a view to charting the way forward. Relevant published texts across the country and the structural conflict theory provided the leverage for this study.

The present study is aimed to analyze the statistical relationship among various water quality parameters and water quality index (WQI). For this, observed results of physico-chemical analysis of 71 ground water samples of study area in pre- and post-monsoon season and calculated water quality index values for each respective sample were taken into consideration. Correlation coefficient between every water quality parameter and WQI values is calculated and for the pairs having highly significant correlation coefficient (0.8<r<1.0) values; regression model is applied and scatter plots are drawn. The systematic correlation and regression study suggested the perfect linear relationship between Fluoride and WQI Values. The analysis provides essential information regarding the dependency of water quality rating on each water quality parameter.

The study examines the challenges behind the succession and sustainability of family businesses. Mentoring was identified as the means to tackle this menace. The study was conducted in Ogbomoso, Nigeria. Eight family businesses were selected through purposive sampling method. The inclusion criteria were operational family businesses in their second or more generation. Data were collected using fifteen semi structured, in depth, face to face interviews with participants. Sampling continue until saturation of the data was reached. Content analysis approach was applied to analyse the data. Family business successors acknowledged mentoring shaped their emergence as the successor of their family businesses. 

In the global economy of the 21st century, international trade will be a key source of economic growth and development. Recent surveys conducted in several countries by the National Foundation of Women Business Owners (NFWBO) indicate that women-owned firms involved in the global marketplace have greater revenues, are more optimistic about their business prospects and are more focused on business expansion than women-owned firms that are domestically oriented. Obviously, expanding into international trade can pay off for women-owned firms. However, it is not clear that smaller enterprises are benefiting from these potential as much as larger firms. In connection with the above here an attempt has made to study the role of women entrepreneurs in economic development.

ABSTRACT:- Exopolysaccharides (EPS) are high molecular weight polymers with long chain composed of sugar residues and secreted by microorganisms into the surrounding environment. Bacterial EPS has a complex mixture of macro molecular poly electrolytes including carbohydrates, proteins and sometimes nucleic acids. Stem and root nodulating isolate of Aeschynomene indica plant was identified by 16S rRNA sequencing as Rhizobium mayense. Efficiency of Rhizobium mayense for EPS production was studied using Yeast Extract Agar as a basal medium with different carbon and nitrogen sources and the incubation was done at 30?C for 48 hours. Surface topology of EPS was found smooth by Scanning Electron Microscopy. Alcohol precipitated EPS was further purified using Sephadex G200 and Sephadex G100 gels. The rheological properties of purified EPS were studied by Ostwald’s Viscometry and BrookField’s viscometetry. Key words: 16S rRNA sequencing, Exopolysaccharide, Scanning Electron Microscopy, Gel Permeation Chromatography, Ostwald’s Viscometry, BrookField’s viscometetry.

In this work, concentrations of radon indoor were measured at 10 locations in Al-Kufa and Al- Najaf cities, using RAD-7 radon monitoring system of Durridge company USA. Some factors affecting on the radon factor have been studied such as times of day (morning, afternoon and evening) and seasons of year (winter, spring, summer and autumn). This study show that the radon concentration indoor increases at mornings, evenings, decreases at afternoon, also increases in winter and autumn, decreases in spring and summer.

Mobile ad hoc networks will appear in environments where the nodes of the networks are absent and have little or no physical protection against tampering. The wireless nodes of MANET are thus susceptible to compromise and are particularly vulnerable to denial of service (DoS) attacks launched by malicious nodes or intruders. Flooding attack is one such type of DoS attack, in which a compromised node floods the entire network by sending a large number of fake RREQs to nonexistent nodes in the network, thus resulting in network congestion. In this paper, the security of MANET AODV routing protocol is investigated by identifying the impact of flooding attack on it. A simulation study of the effects of flooding attack on the performance of the AODV routing protocol is presented using random waypoint mobility model . The simulation environment is implemented by using the NS-2 network simulator. It is observed that due to the presence of such malicious nodes, average percentage of packet loss in the network, average routing overhead and average bandwidth requirement? all increases, thus degrading the performance of MANET significantly.

Sand is an important mineral for the construction industry in the Kenyan society at large. However, protecting the environment in areas where this practice of sand mining takes place has become an environmental concern, given that the demand for sand increases with the growth of industry and construction. Sand mining though sustains the economy of the locals, can lead to considerable environmental damage which varies from pit formation to soil erosion. There is therefore need to put in place measures that can promote the economy of the locals and at the same time conserving the rich and diversified flora and fauna. The objectives of the study were: to identify effects of sand harvesting on land cover, flora and fauna; and to establish sustainable measures of land cover, flora and fauna along riparian land in Kisumu County.It was an experimental research design carried out usingmixed method approaches. A sample size study population of 384 was involved, which comprised of NGO staffs, County Council staffs, local area authority staffs, sand harvesters and the local community. The local communities were randomly sampled while purposive sampling was used to select respondents from the sand harvesters, area chiefs, NGOs and the County Council staffs. Data were collected by means ofself-administered questionnaires, guided interview schedules and observation check list by the researcher. The results indicated that there was negative impact of sand harvesting on land cover, flora and fauna on the riparian land along rivers. It also established the sustainable measures of land cover, flora and fauna in the study area.The research indicated that indeed the harvesting of sand is affecting the land cover, flora and faunaalong riparian land negatively. The vegetation, the wildlife and the land cover are destroyed as the top soil is harvested as sand. Further, the land for agriculture is turned into waste land due to sand harvesting by formation of pits. This has resulted in the loss of the natural beauty of the environment. Because there are also economic gains in sand harvesting, sustainable measures of land cover, flora and fauna along riparian land are recommended. These should include; regulating the harvesting periods or controlled harvesting, re-shaping of the land where sand has been harvested, advocating for continuousawareness and positive education programmes on conservation measures of land cover, flora and fauna and enacting necessary legislative laws aimed at conserving land cover, flora and fauna.

Schiff bases (E)-4-chloro-2-((phenylimino)methyl)phenol, (E)-4-chloro-2-(((2-methoxyphenyl)imino)methyl)phenol, (E)-4-chloro-2-(((4-chlorophenyl)imino)methyl)phenol, (E)-4-chloro-2-(((5-chloro-2-methylphenyl)imino)methyl)phenol were synthesized from 5-chlorosalicylaldehyde and substituted aniline. The synthesized compounds were characterized by elemental analysis, IR, UV, 1H, and 13C NMR. The antibacterial studies revealed that the compounds exhibit broad spectrum antibacterial activity against Escheriochia coli, Klebsiella pneumonia, proteus mirabilis, Pseudomonas aeruginosa and Salmonella typhimurium. The antibacterial activities was affected by the substituent on the aniline part.
