WOMEN AND SOCIAL MEDIA: A STUDY OF GHANAIAN WOMEN BLOGS

ABSTRACT Blogging has become a major tool for people to interact and make known their various perspectives on life and the world at large. The study investigates the usage and practice of blogging by Ghanaian women. Using the theory of technology diffusion and adoption, liberal feminist theory and the sense of agency and community, the study establishes that Ghanaian women are actively engaging with blogs by creating personal journal blogs, writing on diverse themes but predominantly on love...

THE JUNIOR GRAPHIC AND READING HABITS OF YOUNG TEENAGERS

ABSTRACT Reading is a skill that is vital to the development of an individual’s mind and for that matter the growth and progression of one’s life. It is even more beneficial for children when they are in their most impressionable stage of development, to develop good reading habits in them as they progress through the various stages of life as pupils, students, and into the adult life of career-hood. Reading for leisure has been seen as an effective way to cultivate the creative and criti...

A STUDY OF POWER FACTOR IMPACT ON ELECTRICAL INSTALLATIONS IN AJAOKUTA STEEL COMPANY LIMITED, NIGERIA

ABSTRACT Power factor is related to power flow in electrical systems and measures how effective an electrical power system is used. In order to efficiently use a power system, the power factor should be as close to unity as possible. This implies that the flow of reactive power should be kept to a minimal. Maintaining a high power factor is crucial to obtaining the best possible economic advantage for both Utilities and Industrial users. Operating a power system at a low power factor is a con...

Analysis of Electrical Surges in Ajaokuta Power System Network, Nigeria

ABSTRACT The study investigates the electrical surge effects and remedy in Ajaokuta Power System Network located in Kogi State in the North Central of Nigeria, to identify various causes of lightning strokes and highlight various associated effects and to determine surge intensity and magnitude, collection of surge data on distribution and transmission network. The approaches adopted is to develop a preliminary data collection that will address the identified data gap and to review comprehens...

Production and Characterization of Activated Carbon Produced from a Suitable Industrial Sludge

Abstract: The purpose of this study is the preparation of activated carbon using a suitable industrial sludge. The characterization of two types of industrial sludges showed that paper sludge was a better option over rice husk. The activated carbon produced from pyrolysis of paper mill sludge was chemically activated with various activating agents like zinc chloride, potassium hydroxide and potassium chloride. A systematic investigation of the effect of impregnation ratio, activation temp...

Best Distribution and plotting positions of daily maximum flood estimation at Ona River in Ogun-Oshun River Basin, Nigeria

ABSTRACT This paper discusses how normal, lognormal, and log pearson type 3 distributions were investigated as distributions for modelling at site annual maximum flood flows using the Hazen, Weibull, and California plotting positions at Ogun-Oshun river basin in Nigeria.

Assessment of Household Energy Utilization in Ibadan, Southwestern Nigeria

ABSTRACT The critical energy situation in Nigeria suggests the need to study energy and exergy utilization in households, with the aim of pinpointing areas of waste and suggesting alternative measures for effective and efficient utilization of scarce resource.

Laser Application of Nanocomposite Hydrogels on Cancer Cell Viability

Abstract Nanocomposite hydrogels of poly-n-isopropyl were prepared by incorporating gold and magnetite nanoparticles. The nanocomposite-based hydrogels formed were geometrical, ~7.3 mm in diameter and 5 mm thick (in the swollen state). Morphological analysis was characterized by a scanning electron microscope. Drug-loaded hydrogels were subjected to laser heating at 1 W, 1.5 W and 2 W for 20 min in each laser cycle. The metabolic activities of the cells were analysed. The photothermal convers...

Assessing road construction: potential impact of constructing the KwabenyaKitase road on the local economy

Abstract Road construction typically confers significant benefits on the population the road serves. A recent rapid growth of urban residential areas in Ghana has necessitated the construction and rehabilitation of the roads linking these urban areas to major commercial towns in the country. The Kwabenya (Abuom) to Kitase area, straddling Ghana’s Eastern and Greater Accra regions, is a typical example. Using both primary and secondary data sources, the research reveals that agricultural pro...

Recycling of plastic waste materials: mechanical properties and implications for road construction

Abstract This paper presents a recent study on recycling poly-ethylene-tetraphylate (PET), known as plastic waste material in Ghana, to wealth. Composites were produced by heating aggregates together with shredded PET plastic waste material, while bitumen was added to the plasticcoated aggregates. The composites produced were reinforced with 4.5 wt%, 9.0 wt%, 13.6 wt%, and 18.0 wt% PET. Mechanical properties of the fabricated composite samples were studied with a Universal testing machine for...

Fast Detection of Mobile Phones in the Examination Halls, Classroom and Dormitories of Yeji Senior High Technical School Using GSM Technology

Abstract  This work involves the design and development of a digital signal detector which is capable of detecting incoming and outgoing signals from mobile phones. The presence of an activated mobile phone can be detected by this handy, pocket-size mobile signal detector from a distance of one and a half meters, which could be used in preventing the use of mobile phones in examination halls, classrooms, confidential rooms etc. The circuit can detect the incoming and outgoing calls, tex...

THE PORTRAYAL OF WOMEN IN LOCAL AND MULTINATIONAL BRANDS’ ADVERTISEMENTS IN GHANA: A COMPARATIVE CONTENT ANALYSIS

ABSTRACT The objective of this study was to examine the portrayal of women in local and multinational brands’ advertisements in Ghana while drawing a comparison between the two. The study is underpinned by the frame analysis theory and uses qualitative content analysis to determine the portrayal of women in advertisements shown on Ghanaian television between 2011-2016. Literature suggests that advertisers enlist social frames in ads so that their audience can relate to the message of the ad...

DETECTION AND PREVENTION OF MAN-IN-THE-MIDDLE SPOOFING ATTACKS IN MANETS USING PREDICTIVE TECHNIQUES IN ARTIFICIAL NEURAL NETWORKS (ANN)

Abstract Detection and Prevention of Man-In-The-Middle Spoofing Attacks in MANETs Using Predictive Techniques in Artificial Neural Networks (ANN) A Mobile Ad-Hoc Network (MANET) is a convenient wireless infrastructure which presents many advantages in network settings. There are however a lot of challenges faced on such networks; with their relatively much more flexible setups. They are comparatively more susceptible to attacks of various kinds as opposed to their wired cousins. This is due t...

DETERMINATION OF ENGINEERING PROPERTIES OF TWO SOILS AT FOHREC (KADE) AND SIREC (KPONG)

ABSTRACT Agriculture, its operations, and soils properties are inter-related. Cultivation of crops; tillage, irrigation and farm operations, commuting to and from farm plot and building of structures are greatly influenced by the soil specifically its properties. Shear stress, cohesion and angle of friction are parameters that play major roles in influencing how soils are used or worked on. It is, therefore, important to determine the shear stress, cohesion and angle of friction of the soils ...

USING OLPC LAPTOP TECHNOLOGY AS A COMPUTER SCIENCE CASE STUDY TEACHING TOOL*

ABSTRACT The One Laptop Per Child project has succeeded in developing a novel computer that is tailored to the particular needs of the developing world. The use of this example of a modern computer systems design challenge can be a valuable case study as a teaching tool in computer science. The OLPC laptop is a multiple-purpose computer that is rugged, low-cost, low-power, mesh networked, and inexpensive. An overview of the technology in the laptops is given, as well as curricula suggestions ...
