Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous organic pollutants in urban environmentsincluding urban soils. Elevated concentrations of PAHs in urban soils are caused by incomplete combustion of petroleum and coal. This study assesses 16 individual PAH compounds in a total of 112 surficial soil samples. The objective was to assess and compare the levels of contamination as well as examine the main sources of PAHs in four urban agricultural soils using molecular ratios of some specifi...
The most relevant controls on groundwater quality within the Lower Pra Basin in Ghana were assessedusing Q-mode hierarchical cluster analysis (HCA). The objective was to determine the chemical characteristics of the various water groups and subgroups responsible for the groundwater evolution and identify the groundwater recharge and discharge zones within the basin. The Q-mode HCA have characterized hydrochemical data from a total of sixty-eight (68) boreholes and two (2) streams within the b...
Hydrochemical and stable isotopes (18O and 2H) analyses of groundwater samples were employed toestablish the origin of major dissolved ions in groundwater within the Lower Pra Basin. Results showed that, the major processes responsible for chemical evolution of groundwater include: silicate (SiO4)4- dissolutions, ion exchange reactions, sea aerosol spray and pyrite (FeS2) and arsenopyrite (FeAsS) oxidations. The groundwater is strongly acidic to neutral, with pH generally range from 3.5 to 7....
Calcite (CaCO3), dolomite [CaMg(CO3)2], silicatedissolution, ion-exchange and reverse ion-exchangereactions are the predominant processes influencinggroundwater quality in the Savelugu–Nanton District. Themain objective of this study is to characterize groundwaterand delineate water–rock interactions responsible for thechemical evolution of groundwater in the District. Eighty-one (81) boreholes were sampled for quality assessment.Results showed that, the pH of the boreholes are slightly a...
ABSTRACT Contraception play an important role in the life of men and women and is viewed in the wider work context of sexual and reproductive health. Family planning is the arrangement, spacing and limited wishes and socio - circumstance of the parents. But due to their culture, people of Oloku do not always agree to family planning method. The reason for this work was to collect information relevant to the aim of study. Know factors which hinder knowledge and support of family planning, corr...
ABSTRACT Plastics are important for man use. It cannot be eradicated nor forbidden. Then how should we go about the debris/waste of plastics? How can we stop the single-use method of plastic? Should we ignore and look for another alternative? These above are some of the questions we ask ourselves on daily basis TABLE OF CONTENTS Title page Acknowledgments Abstracts Literature review Results Recommendations References
ABSTRACT Malaria is entirely preventable and treatable vector-borne disease which account for an estimated 219 million cases globally, killing about 660,000 people, mostly children under five years of age. The synergistic effects of nutrition in malaria infection were observed in mice fed with different nutrients (protein, carbohydrate, and grower mash) compounded diets for eight weeks prior to infection. All the experimental mice were infected with plasmodium berghei....

Aims: To investigate urinary cytological abnormalities among adult residents of a urinary schistosomiasis endemic community. Study Design: Ethical approval, consent from the village Head/villagers, parasitological survey and cytological analysis of urine. Place and Duration of Study: Adim Community in Cross River State, Nigeria between May and November 2014 Methodology: Urine samples from 160 sex matched adults aged 18–85 years were examined u...
Objectives. The study was to assess the level of knowledge of, perception of, and attitude towards uterine fibroids among women diagnosed with the condition. Methods. It is a cross-sectional descriptive study carried out among women diagnosed as having uterine fibroids in two gynaecological clinics in Lagos, Nigeria. Eligible women were recruited and a structured interviewer-administered questionnaire was used to collect the required information. Statistical analysis of data was done using...
Search result: Eight clinical studies to topics concerning orthodontic bonding, root- and tooth restorations were found. Clinical outcomes: The results indicate a higher cariostatic effect of GIC for orthodontic bonding and tooth restorations in permanent teeth. No difference was found for tooth restorations in primary teeth when compared to fluoride containing composite and root restorations. [‘Preliminary Systematic Literature Searches’ are based on SYSTEM’s periodic systematic sear...
Search result: Three prospective clinical controlled trials were found. Clinical outcomes: The results indicate that there may be a trend that coating can protect Fuji IX GP Extra against wear. [‘Preliminary Systematic Literature Searches’ are based on SYSTEM’s periodic systematic searches of the dental literature and provide first overviews over existing clinical evidence but are limited in the number of databases searched, as well as the assessment of precision and internal validity...
Search result: Five clinical trials were found and traced. Clinical outcomes: The results are conflicting or suggest no difference between conventional GIC and Compomers in regard to their anticariogenic effects after 3-4 years. [‘Preliminary Systematic Literature Searches’ are based on SYSTEM’s periodic systematic searches of the dental literature and provide first overviews over existing clinical evidence but are limited in the number of databases searched, as well as the assessmen...
Search result: Twelve clinical trials were found and traced. Clinical outcomes: The overall results suggest no difference between RM-GIC and Compomers in regard to their anticariogenic effects.

Search result: One clinical trial was found and traced concerning resin-modified GIC (RM-GIC). Clinical outcomes: The material was Fuji II LC (compared to: Tetric Flow and Helioseal F). No trials were identified comparing conventional GIC (C-GIC) with composite resin. [‘Preliminary Systematic Literature Searches’ are based on SYSTEM’s periodic systematic searches of the dental literature and provide first overviews over existing clinical evidence but are limited in the number of datab...
