Title: EMERGENT TECHNOLOGY CLOUD COMPUTING SECURITY NETWORK.pdf Author: Basaky D. Basaky, PhD. & Bakare Kareem, PhD. Abstract: The exponential growth of cloud computing is changing the way organizations are functioning now a days. A cloud based system changes the services seamlessly without expending much time and resources in setting up new systems. Apart from this, there are lots of benefits like scalability, significant cost reduction, high availability and quality in a cloud based system. Although there are many advantages cloud computing, issues related with security and privacy are some of the major challenges, which needs to be addressed for the successful deployment of a cloud based system. Therefore, it is absolutely critical to have a robust security services fully implemented based on cloud-based security framework/Guidelines. At present there are a number of standard security framework/Guidelines like ISO 27001/27002, NIST 800-53, but all these standard are in evolving stage for the cloud computing Environment. Apart from this, the security requirements of an organization also vary based on specific security risks of the organization. This paper first introduces a new set of security control Theory. These principles theory is based on People, Process and Technology Theory (P2T2) from the Enhance Concept Security Matrix (ECSM) basically a cloud based Security Framework CSF.

Title: MATHEMATICAL PROGRAMMING AND PRODUCTION A CASE STUDY OF PORT HARCOURT REFINING COMPANY.pdf Author: Osaroeyaa Princewill & Naam Jonathan Abstract: The Port Harcourt Refining Company (PHRC) is a subsidiary of the Nigerian National Petroleum Corporation (NNPC). PHRC major problem is the allocation of raw materials for the production of petroleum products. Most persons erroneously believe that the only raw material for the production of some petroleum products like the premium motor spirit (PMS), commonly known as fuel in Local palace, Automotive gas oil (AGO) diesel, kerosene, cooking gas (Methane) etc is the petroleum, but the actual fact is that several chemicals called additives are usually mixed in certain proportion to petroleum at various temperature to get these petroleum products. However, the inability of Port Harcourt Refining Company (PHRC) management to get the profitable proportion of this production mix is responsible for the unbearable scarcity of these petroleum products despite the many turn-around maintenances (TAM) embarked upon by successive government. To solve this production mix problem, the linear programming method, as a mathematical programming tool, which has been acceptable as the best method of solving a production mix problem was applied and the result, which is a feasible solution that will enable the management of the Port Harcourt refining company (PHRC) solve the production mix problem was clearly stated.

Title: COMPARATIVE ANALYSIS OF THE NUTRITIONAL AND MINERAL VALUES OF LAND FERN (PTERIDIUM AQUILINUM) AND WATER FERN (NEPHOLEPSIS BISERRATA) CONSUMED IN OKWALE COMMUNITY, NIGERIA.pdf Author: Nyodee G.T., Miikue – Yobe, T. F. B. & Ntaah, L. D. Abstract: This work was on the comparative analysis of the nutritional and mineral values of land fern (Pteridium aquilinum) and water fern (Nephrolepsis biserrata) consumed in Okwale Community, Nigeria. The parameters were analyzed using standard methods of the Association of Official Analytical Chemists (AOAC, 2006), flame Spectrophotometer and atomic absorption Spectrophotometer. In this study, the moisture (83.33%), protein (7.00), and carbohydrate (6.25%) contents of Pteridium aquilinum was higher than the moisture (66.41%), protein (6.56%) and carbohydrate (5.208%) contents of Nephrolepsis biserrata. However, the fibre (10.002%), lipid (9.60%) and ash (2.20%) contents of Nephrolepsis biserrata was higher than fibre (0.62%), lipid (1.30%) and ash (1.50%) contents of Pteridium aquilinum. The mineral values of Pteridium aquilinum and Hephrolepsis biserrata also showed that the potassium (4318.950 mg/kg), iron (689.70 mg/kg), magnesium (465.15 mg/kg), calcium 361.10 mg/kg), sulphate (229.950 mg/kg), sodium (163.65 mg/kg), zinc (107.70 mg/kg), manganese (51.95 mg/kg), phosphorus (36.33 mg/kg), and copper (4.15 mg/kg) contents of Pteridium aquilinum were higher than potassium (78.672 mg/kg), iron (337.40 mg/kg), magnesium (436.20 mg/kg), calcium (135.15 mg/kg), sulphate (114.975 mg/kg), sodium (128.00 mg/kg), zinc (87.70 mg/kg), manganese (43.85 mg/kg), phosphorus (35.82 mg/kg), and copper (1.90 mg/kg) contents of Nephrolepsis biserrata. Chromium was not detected in both ferns. However, the calculated mean value of the minerals of Ptgeridium aquilinum (642.863 mg/kg) is higher than that of Nephrolepsis biserrata (39.967 mg/kg). This is a clear indication that Pteridium aquilinum is more nutritious than Nephrolepsis biserrata. This study therefore recommends that both ferns should be consumed with more preference on Pteridium aquilinum (land fern). Keywords: Nutritional values, minerals values, comparatives analysis, land and water ferns’ Okwale Community. View |

Title: EVALUATION OF WATER QUALITY INDEX AND SALT WATER INTRUSION OF DRINKING WATER SOURCES IN EKEDE COMMUNITY, ANDONI, NIGERIA..pdf Author: Nyodee, G.T., Nwiyor, P.S. & Herbert, A.G. Abstract: The study examined the Water Quality Index (WQI) and Saltwater intrusion of the drinking water sources in Ekede Community, Andoni. The parameters were measured at the various water sources – with standard analytical methods. The calculated values of WQI ranged from 92.15 to 151.28. These values indicated that the water quality status is very poor as well as unsuitable for drinking. The saltwater water intrusion indices such as Simpson ratio (1.86, 1.31 and 1.29); TA/TH ratio (1.04, 1.53 and 1.28); BEX values which are negative and the low values of Na/Cl ratio (0.30, 0.17 and 0.39) all indicated salt water contamination of the water sources in the study area. The very poor, unsuitable and saltwater contaminated water bodies of the study area are not suggestible for use of regular human activities. Therefore, this study recommends that government should come to the aid of the community by providing portable drinking water in order to reduce the over dependence on lake water drinking source.

Title: POLICY MANAGEMENT AND EFFECTIVE PERFORMANCE IN HIGHER EDUCATION IN NIGERIA INFORMATION AND COMMUNICATION TECHNOLOGY AS THE NEXUS.pdf Author: Eunice C. Victor–Ishikaku,PhD. Abstract: Universities in Nigeria are vested with the responsibility of producing manpower for the labour market. To carry out the affairs of the universities to meet this target requires making policies to govern her affairs and activities. Managing such policies properly therefore is vital to the effective and efficient performance of the universities. This can only be done through effective communication. Communication is the network that connects and holds individuals in the institution together; to work together in harmony to achieve the goals of the policies made. It therefore implies that policies must be communicated effectively and efficiently within the system; the individuals in the system must know how to manage such policies by communicating them effectively as at when due for the institution to meet its aims and objectives. Information and Communication Technology (ICT) is a nexus that connects individual for efficient information management; making information to be received just-in-time for proper policy implementation and performance. The discourse of this paper therefore is on the key position of ICT in effective policy management for efficient performance in the universities. It posits the application of ICT in information management in the university system as the nexus between policy making and its implementation to achieve the goals of the university system. Based on this position, some recommendations were made such as provision of ICT facilities within universities; training and retraining of university staff to be abreast with trends in ICT, embracing ICT innovations and change by staff of the university amongst others.

Title: CREATING SELF-RELIANT OPPORTUNITIES THROUGH ENTREPRENEURIAL AND VOCATIONAL SKILLS ACQUISITION A PANACEA FOR CURBING INSECURITY IN NIGERIA.pdf Author: Ogundu I., PhD. Abstract: In this rapidly changing world, the quest for self-reliance opportunity through entrepreneurial and vocational skills has always been the desire of many nations especially in the present face of security challenges. This has triggers many countries of the world to re-evaluate their position and question their roles as nations and consider investing heavily in Vocational and Technical Education (VTE). Thus, Nigeria as a developing nation need a comprehensive functional VTE that will impart and impact the right knowledge, skills and attitudes as well as stir up the productive potentials of the citizenry to achieve self-reliance. Consequently, repeated call for massive reform of current educational practices has consistently been the dream of many Nigerians and has resulted in an increasing recognition of entrepreneurial and vocational skills acquisition as a panacea curbing insecurity in Nigeria. This paper examined the concepts of entrepreneurship and vocational skills acquisition, insecurity and self-reliance. It further highlighted VTE for Self-Reliance, Entrepreneurship and entrepreneurial opportunities in vocational skill acquisition and Strategies for developing entrepreneurial skills through vocational skills acquisition for curbing insecurity in Nigeria. Therefore the paper suggested the following way forward among others that: emphasis should be laid on entrepreneurial skills and functional vocational skills acquisition such as design, production and modernization of indigenous resources among students through practices and vocational skills for achieving self-reliant generation, the federal government should establish a sustainable national exhibition for entrepreneurship student to stimulate the production of high quality audio-visual materials.

Title: PUBLIC PERCEPTION OF ARTESANAL REFINERY IMPACT ON AIR QUALITY IN PORT HARCOURT, NIGERIA..pdf Author: Hyginus B. Oku, PhD. & Numoipre Inainfe Abstract: The paper public perception of artesanal refinery impact on air quality in Port Harcourt has the objective of eliciting vital information on the public perception of observed black soot on air quality index in the municipality. Hence structured questionnaire was administered to the respondents. Over 90% of the respondents are of the view that the high prevalence of black soot in the Port Harcourt municipal area was the product of artesanal refineries located offshore and this has impact on air quality and health of residents. The authors thus include that air quality index could be enhanced through the total stoppage of the economic sabotage occasioned by artesanal refining of crude petroleum. Hence recommend the active involvement of enforcement agencies to tame this ugly development. Similarly, advocate the reorganization of all stakeholders with the intent of implementing modular refineries to tame as well as to ensure that the raw material for this illicit business is not available.

Title: COMPARATIVE ANALYSIS OF BLOCKCHAIN CONSENSUS ALGORITHM POW VS POS BASED ON PERFORMANCE AND SECURITY METRICS.pdf Author: Ojekudo Nathaniel Akpofure, PhD. Abstract: Cryptocurrency has attracted great attention in academic, financial and well as technology. Behind the cryptocurrency is the Blockchain, which is a decentralized digital ledger which records all verified transaction on the network. Transactions within the blockchain are verified using one of many consensus algorithms to resolve the problem of reliability involving many distributed nodes which keep copies of the ledger. This paper presents a comprehensive overview on blockchaintechnology and consensus problems. Since the Proof of Work (PoW) and Proof of Stake (PoS) are the most widely used consensus algorithm amongst cryptocurrency. This study attempts to comparatively analyze typical PoW and PoS consensus algorithm based on performance and security metrics. Finally, we present our conclusion based on our analysis, which suggests that PoS algorithm appears to perform better than PoW algorithm especially on performance metrics such as transaction rate, cost and energy and scalability. However, PoW performs better on security metrics such as; cost of attack, coin age accumulation attack, precomputing attack, nothing at stake problem and initial distribution problem. Future Blockchain Consensus algorithm should consider implementing innovative improvements on both performance and security metrics. KEYWORDS: Cryptocurrency, Proof of Work, Proof of Stake View |
