DEVELOPMENT AND PERFORMANCE ANALYSIS OF HORIZONTAL WASTE PAPER BALING MACHINE

In an effort to mitigate the problem of increasing amount of generated waste papers going to dumpsites for burning directly causing global warning. Horizontal waste paper baling machine was designed, Manufactured and tested using high local content and readily available materials in such a way that, maintenance will not be expensive to ensure sustainability and reliability. The principal parameters of the design included the maximum force (10 KN) of the compression, the distance the piston rod has to move before compressing the waste paper (piston stroke, 609mm), cycled time of 9 minutes and the system pressure. The major components of the waste paper baling machine designed includes the frame, electric motor, coupling, hydraulic pump, pressure hose, directional control valve, filter, pressure gauge, thermometer, tank, and hydraulic cylinder. The machine was tested for performance with a waste paper such as white papers of A4 size used for Photostat and printing upon and found to be able to bale the waste paper into a bale size of 400mm × 400mm × 700mm in 6 seconds and weight of 15kg, the efficiency of the machine was 80%, using the hydraulic power system. The bales produced by this device will aids in simple management, storage and transportation and will enhance the recycle industry

Universal banking and the Nigerian banking sector

In this study we propose that there is a positive relationship between the variables (growth, effective customer service, size of a bank) and universal banking in Nigeria. In support of this proposition, we employed empirical evidence in the investigation. From the result, it was discovered that the size (net assets and market share) has little or no bearing with universal banking. On the other hand, a positive relationship was established between universal banking and effective customer's service, and growth in the Nigerian banking sector. The conclusion was that, universal banking has a positive impact on the Nigerian banking sector and the larger Nigerian economy.Global Journal of Social Sciences Vol. 6 (1) 2007: pp. 31-3

A role of alpha-tocopherol and phylloquinone in the modulation of uterine contractility and reproductive function in mouse models

Background and aim: Alpha-tocopherol has been implicated in reproduction processes, and deficiency of phylloquinone has been associated with serious complications in pregnancy. This study was therefore aimed at investigating the effects of phylloquinone and alpha-tocopherol on uterine contractility and female reproductive function using mouse models. Materials and methods: Both in vivo and ex vivo animal models were employed and designed to assess changes on uterine contractility and reproductive functions in the non-pregnant uterus. The effect of alpha-tocopherol and phylloquinone on spontaneous uterine contractions, oxytocin-induced uterine contractions (11.82 nM) and high KCl-induced tonic uterine contractions (80 mM) were assessed. The effect of subcutaneous administration of alpha-tocopherol (10 mg/kg) on reproductive hormone levels and reproductive tissues were also determined. Results: Alpha-tocopherol increased the force of contractions while phylloquinone decreased the force of uterine contractions. Plasma levels of luteinizing hormone (P < 0.01), estrogen (P < 0.01) and progesterone (P < 0.001) were elevated in the presence of alpha-tocopherol after 6 days subcutaneous administration. Conclusions: Alpha-tocopherol and phylloquinone have been shown to directly modulate uterine contractility and reproductive function and may contribute to the management and treatment of reproductive disorders
