Due to this competition, pricing is no longer an essential but rather quality services and experiences. With Tenack Beach Resort’s vision in upgrading its star rating by 2020, it is on course in improving its facilities and experiences, but through research, a gap in their services was discovered. The project was...

TEXT TO SPEECH SYNTHESIS FOR GHANAIAN LOCAL LANGUAGES (Twi)

Abstract Businesses in Ghana do communicate with each other through letters, telephones, fax, and emails. Due to the growth of technology, most of these businesses are providing their services online to make it convenient for customers. However, these mediums of communication have some limitations when it comes to language. In the instance where the parties involved in the communication speak and understand different languages, it becomes difficult to understand. Businesses would like to reac...

LEGAL MANAGEMENT SOFTWARE

ABSTRACT As the world increasingly progresses towards a technology driven environment, the legal sector is not to be left behind. In the past years, clients got to know about lawyers through recommendation and at the same time lawyers had a challenge reaching out to their clients. Work was slow and tedious as research was conducted on dusty and old textbooks. The basis of this project is to bridge the technology gap between the lawyers and advocates in Africa. Firms that deal with legal servi...

ISOLATION, CHARACTERISATION AND BIODEGRADATION ABILITY OF BACTERIA ISOLATED FROM SOIL CONTAMINATED WITH HYDROCARBONS

ABSTRACT Contamination of land and water bodies by crude oil and refined petroleum products is a major challenge worldwide. Indiscriminate disposal of crankcase oil into the environment has increased hydrocarbon pollution in Nigeria. Microorganisms have been identified as major contributors in fighting pollution. The remediation ability of bacteria isolated from hydrocarbon contaminated organic rich soil has not been fully investigated. This research was designed to study in-situ genera and ...

EPIDEMIOLOGY OF MALARIA IN CHILDREN LIVING AT IGBO-ORA, SOUTH WESTERN NIGERIA

ABSTRACT Malaria transmission is seasonal with higher transmission occurring in the rainy season. The burden of malaria falls mainly on children and causes anaemia and fever. Children of school going age are affected and this leads to absence from school. Blood samples were collected from children aged 10 days to 15 years in dry and rainy seasons. Parasite densities were determined by microscopy. Malaria prevalence was higher in the rainy season than in the dry season. In the dry season, 42.4...

THE CONTRIBUTION OF ENDOCRINE DISRUPTING HEAVY METALS TO OESTRADIOL MODULATION AND SEMEN QUALITY IN NIGERIAN MEN

ABSTRACT Declining male fertility is of global concern and has been linked to the effects of endocrine disruptors on the modulation of oestradiol. These disruptors are also recognised to be toxic to the testes. Selenium and zinc play specific roles in heavy metal detoxification, testosterone metabolism, sperm formation and motility. This study was aimed at identifying the possible contribution of cadmium, lead, selenium and zinc to oestradiol modulation and sperm defects in Nigerian men. One...

Quality Attributes of Biscuit from Acha (Digitaria exilis) Flour Supplemented with Cowpea ( Vigna unguiculata) Flour

ABSTRACT Biscuits were produced from blends of acha and cowpea flours. The blends were lWO& 90% 80% 70% and 60% acha with cowpea flour to make 100% in each. Proximate composition, trypsin inhibition activity, functional properties including water absorption index, fat absorption index, gelation capacity, bulk density and emulsifying capacity of the blends were determined. Biscuits were produced from the blends. Trypsin inhibition activity, physical properties of the biscuit including break st...

Clinical malaria diagnosis in adults: the value of signs,symptoms and antibodies

ABSTRACT In the absence of microscopic examination, the high prevalence of asymptomatic malaria infections and the non-specific symptoms of the disease make clinical diagnosis difficult in highly endemic areas. Data from daily medical records 0f 111 adult volunteers obtained in a 13-month longitudinal survey were analysed using Pearson's correlation to investigate the relationship between parasitaernia and clinical symptoms and to determine the predictive strength of various clinical symptoms...

MYCOTOXIN PRODUCTION AND MOLECULAR CHARACTERISATION OF Penicillium SPECIES ISOLATED FROM MILLET GRAINS (Pennisetum glaucum) (L.) R. Br.) IN SOUTHWESTERN NIGERIA

ABSTRACT Millet, a widely consumed food crop, is subject to fungal contamination during storage. These fungi produce mycotoxins in stored food products. Mycotoxins such as citrinin and ochratoxin produced by Penicillium species have been reported to be injurious to consumers. Knowledge of the fungi involved in the production of these mycotoxins will help in the control of its spread in food products. However, there is dearth of information on the mycotoxins produced by Penicillium on millet ...

A Case Study of the Depth of Fresh/Salt Water Interface Using Values of Freshwater Heads in Groundwater of Variable Density

ABSTRACT Almost two thirds of the world's population lives within 400 km of the ocean shoreline; just over half live within 200 km, an area only taking up 10% of the earth's surface. As the world's population continues to grow at an alarming rate, fresh water supplies are constantly being depleted, bringing with it issues such as saltwater intrusion and increasing the importance of groundwater monitoring, management, and conservation. Constant monitoring of the fresh/salt water interface is n...

Studies on the lifecycle of Aleurodicus dispersus (Rusell) (Homoptera: Aleyrodidae) on potted cassava plant in a screen house

ABSTRACT The life cycle, and morphometries studies of A. dispersus (Rusell), white flies were conducted in a screen house in the Department of Zoology, University of Ibadan, Ibadan. The study revealed that A. dispersus (Rusell) on cassava potted plants leaves, Manihot esculenta (Cranzt) (TMS 91934), have six stages, which include, egg first instar, second instar, third instar, pupa and adult. Trichoderma lignorum a fungal was identified as the cause of high mortality rate which occurred on t...

MOLECULAR CHARACTERISATION OF ANTIBIOTIC-RESISTANT BACTERIA FROM SELECTED WATER DISTRIBUTION SYSTEMS IN SOUTHWESTERN NIGERIA

ABSTRACT The presence of Antibiotic-Resistant Bacteria (ARB) in water sources and treated drinking water is an emerging public health issue. Antibiotic resistance genes and mobile genetic elements (integron and gene cassettes) have been reported as bases of resistance in ARB. Available data on ARB in southwestern Nigeria are based on phenotypic studies. Information on molecular basis of resistance in ARB is necessary to determine the mode of resistance transfer among bacteria. This research w...

Occupational Exposure due to RF leakages within GSM Base Station Cabins in Eastern Nigeria

ABSTRACT The occupational exposure due to RF radiation leaks inside the base station cabin, when working on the Base station Transceiver (BTS) Radios and TX cables and during active radio communication was measured. A total of number 30 base stations Cabins were studied in the eastern part of Nigeria, using a Broad band TES-90 Electrosmog meter. The maximum instantaneous electric field strength obtained from GSM 1800 radio was 3.72 V/m, 16.56 V/m for GSM 900 radio and 11.29 V/m for the Tx ca...

Geoenvironmental assessment of the environs of the Aluminium Smelting Company in Ikot Ahasi, southeastern Nigeria

ABSTRACT The Aluminium Smelting Company, located in Ikot Abasi area, lies within the dominantly clastic rocks of the Benin Formation of the eastern Niger Delta.

MODELLING AND MITIGATING MINOR-THREATS IN NETWORK THREAT MANAGEMENT

ABSTRACT Network Threat Management (NTM) is used to model and mitigate network threats classified as major-threats and minor-threats without exceeding Cost of Detection (CD), Time of Detection (TD) and False Positive Rate (FPR) limits. Existing network threat modelling and mitigation frameworks focused on major-threats because until recently, only major-threats are usually harmful, while minor-threats were perceived non-harmful. Recent studies however have shown that some minor-threats are h...
