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.

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
