ABSTRACT Healthcare workers are at high risk of contracting Hepatitis B virus (HBV) infection through exposure to blood or body fluid among patients and health care workers. This study was conducted to determine the adherence to post-exposure prophylaxis (PEP) with hepatitis B following accidental and inoculation injuries among healthcare workers in the Lagos University Teaching […]
ABSTRACT Hypertension is a multifactoral disorder because of the interaction of risk genes and environmental factors. The angiotensin II is a well known vasoconstrictor that exerts most of its influence through the angiotensin II type 1 receptor. The A1166C polymorphism is a single base substitution of adenine for cytosine at position 1166 in the 3¹ […]
ABSTRACT A study of the knowledge and practice of Universal Precautions was carried out among the healthcare workers of the Lagos University Teaching Hospital in Nigeria. We surveyed 340 healthcare workers consisting of 147 doctors, 101 nurses, 47 laboratory scientists and 9 ward assistances took part in the study. Of the 340 healthcare workers, 330 […]
ABSTRACT Seeds of Piper guineense and rhizomes of Zingiber officinale were evaluated for their insecticidal properties against Callosobruchus maculatus in cowpea seeds. The mean number of eggs laid and mean number of bored sites were significantly reduced (P< 0.05) at all concentrations of P. guineense relative to control (untreated cowpea). The effect of Zingiber officinale […]
ABSTRACT Semi-empirical equation of diffusion was used to model the dynamics and destruction of oil spillage in the coastal waters of the Republic of Nigeria. A Software called “slickmovement” was developed and used to study the behaviour of the oil spilled in the Nigerian coastal waters. The results shows that during the dry season the […]
ABSTRACT With the fact that the Internet is a network of networks, it means that packets (Protocol Data Unit of the network layer) have several possible paths to pass through when leaving its source to get to its destination. This was actually the idea of the United States Department of Defence when they developed the […]
ABSTRACT The special transcendental character of the characteristic equations of the retarded differential system makes it difficult to analyze such systems. Researchers have used various acceptable mathematical techniques to address the issue. In this paper, the convergent properties of an integral equation equivalent of a retarded system were used to establish the existence and uniqueness […]
ABSTRACT Bivariate linear mixed models are useful when analyzing longitudinal data of two associated markers. In this paper, we present a bivariate linear mixed model including random effects or first-order auto-regressive process and independent measurement error for both markers. We fitted these models using SAS Proc MIXED. Download Full Article
ABSTRACT GPRS is a wireless data network, designed to be integrated with existing digital networks, to provide an enhanced data network. Advantages include things such as faster connection times, faster data speeds and more accurate billing (to the kilobyte generated and consumed). This aper surveys the GPRS technology providing a high level view of the […]
ABSTRACT More and more enterprises today are discovering the benefits of mobility through wireless networking. Accessing the network wirelessly from nearly any convenient location within the enterprise provides users with better flexibility and productivity. As a result, Information Technology (IT) decision makers have moved away from the implementation of location-specific wireless access to delivering comprehensive […]
