Design and performance evaluation of supplemental air supplied charcoal stove

Improved charcoal stoves are known to generally develop high thermal efficiencies, but most generate appreciable level of gas emissions which has made them unsuitable for use withinresidential buildings. In order to eliminate this constraint, a supplemental air supply power pack wasintroduced to improve charcoal stove thermal and aesthetic performance. This paper described theexperimental setup, test procedures and results showing optimized performance. Comparisonbetween performance character...

In order to evaluate the claim situation on construction projects, this paper devotes the research and literature review to key problem in claim administration on construction projects in Nigeria. Qualitative research was adopted where secondary data from archives were collected from the physical plannin...

Appraisal of Project Scheduling in Nigeria Construction Industry: A case study of Ibadan, Nigeria

Abstract:Project scheduling plays a vital role in successful completion of a construction project, despite the crucial role of this tool, there still exist many challenges in using it efficiently. Some projects schedules are established at the conception of the project and never evaluated for feasibility until problems arise. Besides, some constructors lack the expertise required for preparing effective project schedule. This study therefore, examines the factors affecting project scheduling ...

Cost and Time Performance of Construction Projects under The Due Process Reform In Nigeria

The Due process policy is a product of the Fderal government public procurement reform of 1999. The policy was meant to be an anticorruption device aimed at ensuring probity, transparency, accountability in the procurement of public goods and services. The need for the reform is long overdue. However, in order to assess the implementation of the Due process policy in procurement of construction projects, the study took a survey study of construction projects awarded and executed in federal hi...

ROLE OF SPIDERS IN BUILDING MAINTENANCE

Spiders are primarily beneficial and their activities should be encouraged in the garden. Pesticide control is difficult and rarely necessary. The best approach to controlling spiders in and around the home is to remove hiding spots for secretive spiders such as black windows and regularly clean webs off the house with brushes and vacuums.Maintenance of a building is the work undertaken in order to keep or restore every part of a building, every facilities or machinery to an acceptable standa...

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...

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...

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...

VARIATTION ORDERS IN BUILDING AND CONSTRUCTION PROJECTS IN THE KOFORIDUA MUNICIPALITY

ABSTRACTVariation order is a common phenomenon in construction projects. It involves an amendment of the original scope of a project as in the contract. Variation orders are caused from various factors.Variations often cause disputes and dissatisfactions among the parties involved in construction projects. Thus, it is very important to control variation orders in a construction project. According to Calibri">Arain and Pheng (2005) the effects of variation orders oninstitutional building pr...

THE DIFFERENCES BETWEEN STRUCTURED LANGUAGE AND UNSTRUCTURED LANGUAGE: PROGRAMING LANGUAGE

INTRODUCTIONA program in a non-structured language usually consists of sequentially ordered commands, or statements, usually one in each line. The lines are usually numbered or may have labels: this allows the flow of execution to jump to any line in the program.Non-structured programming introduces basic control flow concepts such as loops, branches and jumps. Although there is no concept of procedures in the non-structured paradigm[citation needed], subroutines are allowed. Unlike a procedu...
