Cross River serves as a major source of drinking water, transportation, agricultural activities and fishing in Cross River State, Nigeria. Since there is no formal control of effluents discharged into the river, it is important to monitor the levels of metals contaminants in it, thus assessing its suitability for domestic and agricultural use. In order to determine this, three sampling stations...

abstract morphological river models are designed to provide physical insight into the morphological response and to assist river engineers and managers in the design, operation and maintenance of river systems. here deterministic modeling weak for a dynamic and stochastic of nature river environment. specially, these could not predict the exact shape of the river bed, specially e.g. for braided...

INTRODUCTION Hepatitis B virus infection is a major global health problem of public health importance. In a bid to control the infection, the Nigerian government in 2004 introduced hepatitis B vaccine into the National Program on Immunization. There are no studies on the prevalence of hepatitis B in adolescent prior to 2004. The study was aimed at determining the seroprevalence and predictors o...

CONTEXT Disclosure of HIV-positive status to sex partners is viewed as a preventive measure and as a social and legal responsibility for HIV-infected individuals. AIMS The aim of this study is to determine the proportions and factors responsible for disclosure of HIV seropositivity among residents of Cross River State, Nigeria. SETTINGS AND DESIGN This was a cross-sectional comparative stud...

Risk factors for care-seeking choices for childhood diarrhea in Nigeria are poorly understood. They are essential to the control of childhood illnesses because diarrhea is an important cause of childhood mortality. This study explored the contributors to care-seeking choices in Cross River State, Nigeria. Caregivers of children aged 0-59months in 1240 randomly selected households in Cross River...

Analyses and investigations on river flow behavior are major issues in design, operation and studies related to water engineering. Thus, recently the application of chaos theory and new techniques, such as chaos theory, has been considered in hydrology and water resources due to relevant innovations and ability. This paper compares the performance of chaos theory with Anfis model and discusses ...

Groundwater, being a vital resource, needs to be developed with proper understanding about its occurrence in time and space. Unscientific sand mining is a dominant environmental issue in this humid tropical river basin namely Bharathapuzha river basin geographically on central part of Kerala state, southwest part of India. The sandy layers along the river course declines its water holding capac...

Large-Scale Particle Image Velocimetry (LSPIV) is an effective method for the measurement of the river surface flow velocity. For the wide cross-section river, in the near-field area of river surface image there are small and clear targets. But the flow tracers are almost invisible in the far-field area because of the resolution limit of one single video camera, which makes it difficult to comp...
