ABSTRACT Construction works estimate inaccuracies and none performance have made the imprecise cost estimating practice subjective. This study assessed the dimensions of cost estimating risks influencing building projects’ estimates. The objectives were to identify sources of cost estimating risks; determine critical risk influencing building project cost estimating; and to investigate management practices for improving building works estimates. The study data were collected through structu...
This paper discusses the controversy surrounding the level of success and competitiveness of the thirdparty ship management sector as well as the reasons or factors driving this development or lack thereof. Opinions are divided on the share of the total world fleet which is being managed by the professional ship management sector. Also, significant discoveries were made pertaining to required share of the world fleet the third-party ship management sector needs to manage to be regarded ...
Abstract Investigations are ongoing for continuous improvement in the properties of stabilized earth for low cost housing. This research examined the influence of palm fibre on the characteristics of cement stabilized laterite interlocking bricks. Specific objective is to examine engineering properties of cement stabilized laterite with palm fibre additives and to compare the cost per square meter with conventional sandcrete blocks. Seventy-two (72) bricks were produced comprising six dif...
ABSTRACT This study investigates the effect of curing methods on the compressive strength of concrete with fine and coarse aggregates components fully and partly replaced with lateritic sand and periwinkle shell respectively. A total of 90 cube specimens of 100 x 100 mm dimensions for each percentage replacements ranging from 10 to 40% percentage replacement of fine aggregate with lateritic sand and coarse aggregate with periwinkle shell and 100% percentage replacement of fine aggregate w...
ABSTRACT The quest for the government to provide more affordable housing for the masses has necessitated more researchers to continue to investigate alternative means of low cost Building materials. Earth made bricks have been recognized as one of the oldest building material. It is not enough to provide these low cost houses but more efforts should be geared towards durability and other mechanical properties. This research examines performance characteristic of earth made brick to determ...
Abstract This research tends to compare the workability and compressive strength of granite against periwinkle and palm kernel shells as coarse aggregates in concrete production. Specific objective is to determine the workability of local substitute for granite using periwinkle and palm kernel shell as coarse aggregate, and to compare the compressive strengths of periwinkle and palm kernel shells with granite based concrete using different concrete mixes. The One-hundred and eight cubes p...
Abstracts This paper is an attempt to examine the educational issues of entrepreneurship Technical and Vocational Education (EVTE) for preparing the workforce of tomorrow. Concepts, Reforms, challenges and the way forward for entrepreneurship vocational and technical education in Nigeria are discussed. Nigeria aspires to become a major player in the world economy in line with her Vision 20-2020. It is very clear that most crucial vehicle for attaining such ambitious goal is a skilled and com...
Abstract: In this work, we study the soft vector space introduced by A. Sezgin Sezer et al. in 2014. We define normal soft sub vector space, normalistic soft vector space, trivial normalistic soft vector space and whole normalistic soft vector space. We also present the properties of operations such as union (∪ ), intersection (∩ ), restricted union (∪𝑅), extended intersection (∩𝐸), restricted difference (~𝑅), AND (⋀ ) and OR (⋁ ) operations and investigate their inter-re...
ABSTRACT There has been a proliferation in the activities of crude oil exploration across the globe as a result of increase in high risk of oil spillage and the accompanying environmental hazards. In Nigeria, this has been the order of the day since the initiation of the first petroleum industry in country’s Niger delta region. Oil spills have been recurrent and impacting damaging effects on the environment particularly within the oil-producing region. This research therefore examines impac...
This is a business case on how to establish a cyber cafe.
ABSTRACT This research was carried out to assess and establish the criteria used by consultants in prequalifying and selecting Mechanical and Electrical subcontractors in building projects in Nigeria. Field survey involving construction consultants and staff in the client organizations in Lagos was conducted. Data were collected with the aid of structured questionnaires. 60 well-structured questionnaires were administered on the professional survey, 53 responses were gotten back which ga...
The six year insurgency across the North-Eastern part of the country has triggered serious security instability and escalated the food security situation in the Northeast. With the return of relative peace in many communities in Borno state, the returnee IDPS are confronted by challenge of livelihood considering the fact that they are predominantly peasant farmers and their farming activities have been truncated by the insurgency. Secondly the little they reserved in their granaries has been ...
ABSTRACT Cancer of the lungs has been one of the main causes of death recently, and still is, Lung cancer, also known as lung carcinoma, is a malignant lung tumor characterized by uncontrolled cell growth in tissues of the lung. This growth can spread beyond the lung by the process of metastasis into nearby tissue or other parts of the body. Most cancers that start in the lung, known as primary lung cancers, are carcinomas. The two main types are small-cell lung carcinoma (SCLC) and non-small...
SYNOPSIS Quality control can be seen as the activities that sustain the quality of a product in order to satisfy a given requirement or meet certain standards. (McGraw-Hill Dictionary, 2003). It is applicable in all phases of the production cycle. In food products, qualities such as composition, structure (molecular, microscopic and macroscopic), physicochemical and sensory attributes are all analyzed. These analyses are carried out both to satisfy customers’ and meet regulatory stan...
ABSTRACTThis research work was carried out to evaluate the laboratory analysis of pipeline products marketing company (PPMC) depot operations. In the course of the research many scholarly articles on the subject matter were reviewed from which the researcher got lot information concerning the topic at hand. Thus making the research work a reliable source of information as far as facts about petroleum products marketing company (PPMC) is concerned.The Pipeline Inspectorate is charged with the...
