Nutrient and sensory evaluation of cassava cake (kpo-kpogarri) enriched with coconut and palm weevil larvae (Rhyncophorous ferrugineus)

The Nutrient composition and sensory evaluation of cassava cake commonly called kpo-kpo garri enriched with palm weevil larvae (Rhyncophorous ferrugineus) and coconut was investigated. Using standard analytical methods, the cake sample was subjected to proximate and sensory analysis. There were differences in the nutrient composition of the enriched cassava cake and the non-enriched (control) cake. Values varied from 0.31-3.87%, 1.07-18.14%, 2.47-6.14%, and 0.15-10.30% for Ash, protein, fibre and fat respectively. Carbohydrate content decreased with enrichment, 88.08 to 53.26% whereas moisture decreased with enrichment 4.78% as against 6.72% in the control. The enriched cassava cake was liked extremely over the control in terms of taste and overall acceptability from the organoleptic test. Results from the study, shows that the enriched cassava cake has better nutritional qualities than the control sample hence will be capable of reducing the level of protein-energy malnutrition. The need to improve nutritive quality of local foods using nutrient rich ingredients has been promoted. Palm weevil larvae and coconut are rich in Protein, Lipid, Carbohydrate, Fibre, minerals and vitamins. Development of this type of product could be a source of livelihood to the local people and create job for the unemployed youths

Design and Simulation of a Secured Enterprise Network for Faculty of Engineering, Rivers State University

Institutions generally seek for a network infrastructure solution that intelligently combines voice and data networks. To compete globally, It has become necessary for the Faculty of Engineering to build and setup a secured enterprise network solution to drive the rapid engineering and technological advancement of the University. The aim of this study is to develop a secured, scalable, available, and manageable enterprise network for the Faculty of Engineering, Rivers State University, Port Harcourt, Nigeria. In this article the various services that comprise the enterprise network as a unit have been put together using the Hierarchical Network Model. The physical and logical network topology was designed for the Faculty of Engineering infrastructures and the results from the simulation showed that any user who tried to connect to the network and initiated http traffic were redirected to the authentication server for verification of credentials, before being allowed on the network. The result also shows that the Cisco Adaptive Security Appliance, the Core Router, the distribution switches and the integrated service routers were properly configured. The design reduced network device load and the time to identify network issues to resolve them. The configured network security provided availability, integrity, and confidentiality. This design also enhanced rapid connectivity, and the inclusion of new devices did not affect the transfer of packets. Finally, the specifications and commands used in this study is a model that could be modified and deployed for other Faculties or Universities.

An investigation into the implementation of Building Information Modeling in the Middle East

Architectural, Engineering and Construction (AEC) industry. There have been many changes in the past few years in the use of BIM and how to implement BIM in the AEC Industry. The purpose of this research is to examine the current status of BIM in the Middle East by exploring the extent of adoption of BIM among stakeholders in the AEC industry in this region. To this end surveys were sent out to 297 and empirical statistics have been applied. The respondents acknowledged they were aware of the benefits of BIM in terms of it being a more effective method for designing and managing construction projects by supporting collaboration, improving the quality of the design by providing the ability to closely visualize designs in 3D and rendered forms and providing a platform which would facilitate the sharing of information relevant for design, construction and maintenance of buildings over their entire lifecycle. However, only 20% of AEC organizations in the Middle East are using BIM or are in the process of adopting BIM, with more professionals beginning to adopt BIM although most professionals within this region still look at BIM just as an advanced AutoCAD tool. Raising awareness related to the benefits of BIM and increasing training opportunities in the Middle East are necessary in order to allow all stakeholders to benefit substantially from BIM

University first year chemistry students’ and teachers’ perception of difficulty of select topics in organic chemistry in rivers state of Nigeria
