ABSTRACT

The increasing failure of bridges piles and other structures faced by the construction industry in Nigeria due to weak concrete strength has made it necessary to understand the causes of failure of these structures. Research was carried out to study the mix design for concrete grade 30N/mm2 for bored piles. Tests on aggregates from Kaduna and cement from Dangote were carried out and concrete cubes were cast in order to determine the compressive strength and densities. Three tests were carried out before we could arrive at satisfactory results as specified by the B.S 4450. The compressive strength of the concrete cubes at seven days and twenty eight days were determined. The strengths of the first tests were 18.7 N/mm2, 20.0 N/mm2, 19.4 N/mm2 and 28.9 N/mm2, 27.6N/mm2, 26.7N/mm2 respectively. The second tests were 19.6N/mm2, 19.1N/mm2 and 30.2N/mm2, 29.9N/mm2, 29.3N/mm2 respectively. The third test which gave us the desired results were 24.4N/mm2, 23.9N/mm2, 24.3N/mm2 and 32.2N/mm2, 32.4 N/mm2, 31.9N/mm2 respectively.   The standard consistency of the cement tested was 28% with initial and final setting time of 2hr. 44 minutes and 5hr. 54minutes respectively. The densities of the cubes at seven days and 28dyas were also determined. The first set were 2.36 g/cm3, 2.34 g/cm3 2.32 g/cm3 and 2.41 g/cm3, 2.39 g/cm3, 2.43g/cm3 respectively. The second set were 2.41 g/cm3, 2.39g/cm3, 2.43g/cm3. And 2.44g/cm3, 2.46g/cm3, 2.42g/cm3 respectively. The third set were 2.39g/cm3, 2.40 g/cm3, 2.36 g/cm3 and 2.41g/cm3, 2.39g/cm3, 2.40g/cm3 respectively.

ABSTRACT

The menace of IP spoofing across the globe continues to pose challenges to administrators and stakeholders in today’s networked world. Online criminals repeatedly attempt to circumvent traditional authentication safeguards through sophisticated attacks that specifically targets consumers, enterprises and citizens. The detection and prevention of malicious behaviors that can compromise the security and trust of a computer system are of primary concerns. In this paper, the challenges posed by IP-spoofing in network environments are examined. Various threat cases are identified and methods of mitigation are recommended. This enables third-party software developers to design and implement defense mechanisms against organized and systematic fraudulent attacks on computer

ABSTRACT

This study examines the Nigerian money market. It instruments and the influence of excess reserve ratio, interest rate as monetary policy tools to control the flow/level of funds in circulation. Finally, a linear regression analysis is run using SPSS to determine how effective these monetary policy tools adopted have influenced the demand for money in Nigeria since 1980. It was therefore recommended that the CBN should discourage the use of short-term funds to finance long-term projects among others.

 ABSTRACT

In most of the corruption allegations in Nigeria, real estate acquisition is a common phenomenon. Corrupt public office holders are been alleged of acquiring chains of properties in different locations of the country. This paper focused on the reasons behind acquisition of real estate by corrupt public officers and the manipulation in land administration in Nigeria. Literatures were employed to achieve the aim. It is not that these corrupt public officers can’t fulfill their real estate investment dream in a just way, but some societal malfunctioning factors encourage corruption when they were trying to fulfill their real estate investment dream. Some of the factors that encourage corrupt public officers resulting to corruptible means when they are trying to fulfill their real estate investment are: absence of good mortgage system, anti-corruption policy, prestige associated with property ownership e. It was also observed, that real estate market can be a good indicator of corruption just like the financial system if well harnessed. The following solutions were made to reduce real estate acquisition with embezzled funds: Implementing functional mortgage system, monitoring of property transactions, adopting of local building materials, collaborating with built environment professionals, implementing social housing scheme.

ABSTRACT

Credit risk refers to certainty of loss due to beneficiary’s inability to make payments on any type of debt, while credit risk management is practice of mitigating the loss by understanding the adequacy of both a bank’s capital and loan loss reserves at any given time. Financial ratios are mathematical comparisons of financial statement in the balance sheet (BS) in question, helping the stakeholders to know the situation bank’s situation for improvement. Microfinance Banks (MFBs) are financial institutions licensed to provide diversified, affordable and dependable financial services to the active poor, in a timely and competitive manner that would enable them to undertake, finance and develop long-term, sustainable entrepreneurial activities, established in December, 2005 in Nigeria, when it was obvious that with an overall data of over 140 million, only about 35 percentage of Nigeria have access to financial services and that the remaining 65 percentage relied on the informal sector. There are many types of financial ratios, but this paper will only concentrate on seven (7). The main objective of this paper is to assess the performance and sustainability of the Nigerian Microfinance Banks (NMFBs) in relation to credit risks and financial ratios positions. The specific objectives are to assess whether the seven calculated ratios of: Current; Quick; Debt-Equity; Total Assets to Total Debts; Proprietary; Inventory Turnover and Gross Profit conform to their standard ratios. The Balance Sheet (BS) of the selected NMFBs as at 31st December, 2014 as indicated in Table 2 as one of the secondary data as well as interviews conducted with the operators and borrowers of NMFBs through the questionnaires as primary data were used. The CAMEL approach analysis was used to arrive at the financial ratios positions of the NMFBs. This paper, therefore, recommends regular and continuous credit risk identification, assessment of performance and sustainability as well as sound corporate governance. If NMFBs are to survive and grow in order to achieve the developmental objectives to the economy, the calculated ratios must conform to their standards ratios as one of the findings.

ABSTRACT

Bank performance has been identified as a function of many variables of which branch banking is one. In a country where branch banking enjoys prominence over other banking structure, one tempts to trace the mechanism through which the established branches translate to economic growth. This is the major objective of this study. The study made use of Autoregressive distributed lag bound test approach to cointegration to analyse the impact of branch banking on economic growth in Nigeria. The study concludes among others that branch banking is negatively related to economic growth. This conclusion is in tandem with macroeconomic theory that establishes the fact that savings among others constitute leakages in any given economy. The study therefore recommends that government should provide an enabling environment for transaction velocity to be on the rise. This will have an ultimate positive effect on aggregate demand and economic growth.

ABSTRACT

This research work study focuses its attention on the role of commercial banks in the development of Nigeria economy. The study is aimed at presenting small scale business owners with the survival strategy in a period of economic depression. Secondary data were collected from various recent journals and text books. The study shows that commercial banks have impacted positively on the development of biz scale businesses in Nigeria. Nevertheless, it was concluded that commercial banks should sustain their borrowing to small scale businesses and also recommended among other things that commercial banks should introduce measures to encourage small business owners to have access to long term loan.
