DESIGN OF A PORTABLE DOMESTIC REFRIGERATOR (1)

ABSTRACT This project work is designed mainly for the preservation of foodstuffs, storing of medicines and the cooling of water and drinking fluids in our homes and offices. In the choice of the necessary parameters for the design, Dichlorodifluoromethane, Freone (R12) is used as the refrigerant. An evaporating pressure of 1.237 bar and condensing pressure of 13.66 bar and corresponding temperatures of -25°c and 55°c was considered and the volume of the inside of the refrigerator w...

EVALUATION OF FACTORS AFFECTING CONSTRUCTION COST PERFORMANCE IN CONSTRUCTION SITES IN AWKA

Construction industry in Nigeria had been a major source of employment for 70% of labour in the country, thus it controls the capital flow, as well as labour resources, which has cost implications. Adequate management of these resources is considered an important aspect of project works; so also if the resources are adequately harnessed, issues that pertain to cost overrun would not arise which could result to variations and claims. The growing need for construction of all types coupled with ...

MAINTENANCE MANUAL AND INSPECTION OF BUILDING

The study emphasised on the maintenance manual and inspection of buildings. The paper reviewed the existing literature on building maintenance, and inspection of building, types of maintenance, causes of maintenance, inspection types and procedure, stages of maintenance, and factors influencing the decision to carry out maintenance work. The study utilized a structured questionnaire which was administered on the maintenance management industry and house owners in the study area. The analysis ...

APPRAISAL OF APPLICATION OF BUILDING FACILITY MAINTENANCE OF PUBLIC BUILDING IN FEDERAL POLY OKO

This study is on an Appraisal of application of building facility maintenance of public buildings in Federal poly Oko. Some of the objectives include; determining the nature and types of public building, to examine the current condition and state of maintenance of public buildings, to identify the underlying factors that militated to poor maintenance of public buildings and make suggestions and recommendations towards the adoption of effective maintenance policy.        &n...

DIMENSIONS OF COST ESTIMATING RISKS INFLUENCING BUILDING PROJECTS’ ESTIMATES IN AKWA IBOM STATE

ABSTRACTConstruction 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 structur...

Strategic Overview of Third Party Ship Management: Key Success Factors

This paper discusses the controversy surrounding the level of success and competitiveness of the third￾party 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 a...

INFLUENCE OF PALM FIBRE ON THE CHARACTERISTICS OF STABILIZED LATERITE INTERLOCKING BRICKS

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 comprisin...

EFFECT OF CURING METHODS ON THE CHARACTERISTIC STRENGTH OF CONCRETE WITH LATERITIC SAND AND PERIWINKLE SHELL

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 a...

COMPRESSIVE STRENGTH PERFORMANCE OF CEMENT STABILISED EARTH MADE BRICKS FOR LOW COST HOUSING. R

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...

COMPARATIVE ANALYSIS OF THE MECHANICAL PROPERTIES OF CONCRETE CONTAINING PERIWINKLE

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 eigh...

Entrepreneurship Technical and Vocational Education - A Conceptual Framework for Preparing the Workforce of Tomorrow

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 skille...

Properties of Soft Vector Space Operations

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...

ANALYSES OF THE IMPACTS OF MARITIME POLLUTION ON MARINE ENVIRONMENT: CASE STUDY OF NIGER DELTA REGION, NIGERIA

ABSTRACTThere 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 impact...
