Arithmetic of Analysis (Supremum and Infimum)

I can still remember my expression and feeling when we were asked to show that sup(A + B) = sup(A) + sup(B). It was an herculean task because the concept was too difficult to grasp with the use of approximation property until I discovered an easy route. In a bid to restrict my papers to just few pages, I will focus more on examples than theorems.

A Report on Using Geographic Information System (GIS) to Select Solid Waste Disposal Site: A Case Study in Techiman Municipality, Brong Ahafo Region of Ghana

ABSTRACTSolid waste management over the years has been a serious problem on the nation Ghana. This solid waste materials are generated by humans in the cities and municipalities of almost all developing countries. In this country, it is one of the most pressing concerns of the government because of the health problems that comes with it when not managed well. In most countries locating a suitable site for the construction of landfills is not easy. With the invention of the Geographic In...

MULTI-DERIVATIVE HYBRID METHODS FOR INTEGRATION OF SECOND ORDER ORDINARY DIFFERENTIAL EQUATION WITH INITIAL CONDITIONS

ABSTRACTIn this study, new multi-derivative hybrid methods for the integration of general second order initial value problems ofordinary differential equations are considered. Linear multistep formula was used in the development of the methodstaking Taylor series as the basis function. For the methods K=1 and K=2, the unknown parameters was solved forusing systematic reduction of simultaneous nonlinear equations. Due to the lapses in number of equations compared tothe number of unknowns, we m...

COMPARATIVE CHARACTERIZATION OF SOME PORTLAND CEMENTS SOLD IN SOKOTO CITY.

ABSTRACTThe aim of this research was to characterize some Portland cements (Bua, Dangote and Sokoto cement) sold in Sokoto city using standard methods; due to the persistent collapse of buildings. The results showed that Sokoto cement recorded the least CaO content (58.99%) while Dangote cement had the highest CaO content being 61.56%. All the samples have Al2O3, SiO2 and Fe2O3 contents within the acceptable limits with the exception of Dangote with SiO2 content being below the required stand...

Schistosoma haematobium and Plasmodium falciparum single and concomitant infections; any association with hematologic abnormalities?

Aim: To assess the association between single infection and co-infection status of the twoparasites with hematologic profiles in school children.Methods: A cross-sectional epidemiological survey was carried out on a total of 202 schoolchildren between ages 6-18 years (mean age 11.5 ± 2.6 years). Urine and blood sampleswere collected by standard methods for concurrent microscopic diagnosis of Schistosomahaematobium and Plasmodium falciparum infections respectively. The following hematologicp...

A pilot biomonitoring study of bladder tumor antigen (BTA) in aflatoxin exposed Nigerian villagers

AbstractObjective: To correlate the levels of bladder tumour antigen (BTA) with aflatoxin M1 (AFM) in a humanpopulation in Nigeria.Subjects and methods: A pilot, observational study was conducted with 22 human subjects randomlyrecruited from a Nigerian rural community. Serum and first morning urine of participants were analysedfor human BTA and AFM1, respectively, using quantitative ELISA assays.Results: All the subjects were positive to AFM1 (mean= 0.235± 0.072 ng/mL) while 19 were positi...

Bioactive Constituents and Antibacterial Screening of Two Nigerian Plant Extracts Against Selected Clinical Bacteria

Abstract Background: The growing desires to combat antibiotic resistance among pathogenic bacteria necessitate the need to search for new antimicrobials agents from other sources such as plants. Objectives: The present study investigated the antibacterial activities and bioactive components of Nymphaea lotus and Spondias mombin against selected clinical bacteriaMaterial and Methods: Extracts of N. lotus and S. mombin were prepared by 72 hours maceration in 70%methanol. The antimicrobial susce...

Vernonia amygdalina: A folkloric herb with anthelminthic properties

Vernonia amygdalina, a widely grown shrub plant in Africa is consumed as vegetable and has high medicinalvalue. It has gained wide application in the treatment and management of various diseases. Theleaves are useful components for herbal medicine constitution. The plant’s activities is a result of diversebioactive compounds isolated from the different parts of the plant. These metabolites have specificallybeen efficacious against parasites especially worms. The mechanisms of activities i...

Plasmodial Infection and Haematological Parameters in Febrile Patients in a Hospital in Oyo Town, South-western Nigeria

A cross-sectional study on Plasmodium infection was conducted among 158 febrile patients (65 malesand 93 females) reporting to Oyo State Hospital, Oyo, South-western Nigeria. Parasitological andhaematological examinations of the blood samples were conducted. An overall infection rate of 29.7%was observed with parasite densities ranging from 96 - 64680 asexual parasites/µL blood. Thepercentages of infected male and female individuals were 27.7 and 31.2%, respectively. The least(12.5%) and the...

Lymphatic Filariasis in Southwestern Nigerian Rural Communities: A Cross-sectional Survey of the Knowledge, Awareness, and Predisposing Factors

AbstractBACKGROUND Nigeria is the second most endemic country in the world for lymphatic filariasis, withcontrol efforts often hampered by poor community awareness and involvement in intervention strategies.OBJECTIVE The aim of this study was to assess the knowledge, perception, and psychosocial aspects of some residents in Nigerian rural communities about lymphatic filariasis in order to develop disease control and intervention strategies with active community involvement.METHODS A standar...

Plasmodium Falciparum and Hepatitis B Virus Infection in Nigerian Urban Population

Dear Editor,Infection due to Plasmodium falciparum is a serious public health threat in sub-Saharan Africa. Malaria endemic foci are often times affected by other infectious agents which may contribute to the clinical episodes of the disease. 1Hepatitis B virus is one of such infectious agents that coexistwith P. falciparum in most endemic areas. Although the accurate infection status due to hepatitis B virus infection is not yet known, an estimated 350 million persons worldwide are chronic c...

MOLECULAR CHARACTERISATION OF BULINUS SNAILS – INTERMEDIATE HOSTS OF SCHISTOSOMES IN OGUN STATE, SOUTH-WESTERN NIGERIA

Abstract: Freshwater snails of the genus Bulinus O. F. Müller, 1781 are intermediate hosts for schistosomes, trematode parasites which cause schistosomiasis. The genus includes closely related species complexes with restricted gene flow between populations of each taxon. Despite their importance as intermediate hosts, unambiguous identification of these snails remains challenging. We applied molecular approach to their identification to achieve a better understanding of the epidemiology of s...

Food-borne human parasitic pathogens associated with household cockroaches and houseflies in Nigeria

Cockroaches and houseflies pose significant public health threat owning to their ability to mechanically transmit human intestinal parasites and other disease-causing microorganisms. This study aims at assessing the vectoral capacity of cockroaches and houseflies in the transmission of human intestinal parasites. Intestinal parasite external surface contamination of 130 cockroaches and 150 houseflies caught within dwelling places in Ilishan-Remo town, Ogun StateNigeria was determined. Coc...
