ABSTRACT: A quantity surveyor is a professional with expert knowledge on construction cost and contracts. In a construction project development, a quantity surveyor performs the following roles among others liaising with clients to identify their needs; estimating quantities, costs and time scales for material and labour; preparing tender and contract documents.; identifying and weighing up commercial risks. Majority of Nigeria Quantity surveyors (QSs) still performs their roles by using prim...
Abstract: Tasmanian devils are the largest living carnivorous marsupial found in the wild of Tasmania. These species are being threatened by a cancerous tumour disease, the Devil Facial Tumour Disease (DFTD). The disease affects the facial areas and has led to a considerable popula tion decline. In this thesis, mathematical models for transmission of DFTD are developed and analysed to investigate the significance of feeding and mating related contact, optimal control and fractional-order cha...
Abstract: We have recently argued that, because microbes have pervasive – often vital – influences on our lives, and that therefore their roles must be taken into account in many of the decisions we face, soci ety must become microbiology-literate, through the introduction of relevant microbiology topics in school curricula (Timmis et al. 2019. Environ Micro biol 21: 1513-1528). The current coronavirus pan demic is a stark example of why microbiology literacy is such a crucial enabler of...
Abstract: Engine efficiency could be increased if valve timing could change with engine revolutions per minute. Poppet valves are fitted with strong springs which return them to their rest positions after being pushed down by cam lobes. Overcoming the spring loaded camshaft drive train requires a lot of engine power. Valve lift, lift duration and phase cannot be adapted with cam lobes on the camshaft but electromagnetic actuators or hydraulic/pneumatic phasing mechanisms could achieve change...
Abstract: In attempting to answer the question of whether the Office of the Auditor General is doing enough to protect the sensitive data in its possession, I start off by stating the current information security trends. The trends highlight an upward rise in data breaches despite the numerous traditional approaches to secure data and network resources like firewalls, antiviruses, anti-malware gateways etc. In validation a study is performed at the Office of the Auditor General. Analysis of ...
Abstract: Enterprise Resource Planning (ERP) systems are one of the technologies that many organisations, including Small and Medium Enterprises (SMEs), have adopted. However, most of commercial ERP packages are designed for large-scaled companies. More complex nature of business processes in large companies makes it difficult for SMEs to adopt commercial ERP packages. The high costs of ERP system implementation mean that SMEs need to seek for alternative solutions which are less expensive....
Abstract: The growth of technology advancement has promoted a borderless environment among users, organizations, global industry and easy access to information. The use of the internet and computer systems in a teaching environment parallel increased the number of threats in today's world. Lack of information security practices is the major cause of security breaches. Information security needs to be addressed amongst users for the protection of organizational assets. Human knowledge, attit...
Abstract: Botswana is lagging behind in active participation in stem cell research. The research is yet to take off in the country. In order for stem cell research to be established in Botswana, the people of the country have to accept the research as affording a viable therapy alternative to conventional medicine. This study aimed to evaluate and analyse attitudes of the people of Botswana towards the establishment of stem cell research in Botswana. A survey study was conducted to examine p...
Abstract: The smart grid has an important subsystem known as the Advanced Metering Infrastructure (AMI), responsible for measuring customer consumption of electricity. The AMI subsystem has smart meters as one of the components and they play a vital role in enabling communication between the utility provider and consumers. Smart meters can report real-time electricity consumption readings of the consumer to the utility. Securing this communication link from attacks remain very important for ...
Abstract: There has been a myriad of negative implications on teaching and learning at tertiary level that came along with the emergence of Covid-19 pandemic. The purpose of this paper is to investigate the lessons and opportunities presented by the pandemic to the learning and teaching process in Higher Educational Institutions (HEIs). The study employed a survey design and used diary and semistructured questionnaires as key data generation tools. A sample of 80 lecturing staff was used fro...
Abstract: Water distribution systems mostly involve laying of pipes with the digging of trenches to lay down water pipes as a significant activity. During rainy seasons, trenches tend to fill-up with rainwater before the said pipes could be laid. This poses a danger to workers and residents due to potential landslides. This paper presents the design and simulation of an autonomous anti-rain construction site cover system (AARCSCS), which automates the process of covering a trench or excavati...
This research aims to identify the specific challenges faced by ICT students at Young Achievers' School of Caloocan INC. when learning programming and examine how these challenges impact their academic performance. By conducting this research, valuable information can be gathered to inform educational stakeholders about the difficulties students face when learning programming. The findings will aid in formulating targeted interventions, instructional methods, and support mechanisms to addres...
In the sense that the materials involved in this project were capital intensive more especially cement, so in carrying out the work one must have to be careful in the selection and collection of materials to be used in the casting of the concrete.The materials used are coarse aggregate (granite) fine aggregate (sand). The coarse aggregates used in this work were collected from Ishiagu while the fine aggregate was collected in front of the carpentry’s workshop on the campus.The test conform ...
Abstract Kathonzweni Sub County has been posting poor results in Kiswahili language. This prompted the researchers to undertake a study in the Sub County.

This study was guided by Teacher Efficacy theory. The study was conducted in Kathonzweni Sub County, Kenya. The target population comprised of 60 Kis...
ABSTRACT This paper highlights the legal facets of maintenance practice with special emphasis on Building. It begins with an overview of building maintenance and proceeds to identify the legal implications for owners and occupiers of buildings. This is done by reviewing section 72 of both the Housing Acts 1961 and 1969 of the United Kingdom, the Joint Contract Tribunal and the tort of negligence. The paper also takes a look at the building deterioration and liability in law and again highligh...
