Introduction

Field density testing is significant for assessing the soil properties of a site identified for a project. The assessment of soil property done through field density testing is aimed a verifying that the soil contained the required properties for the type of project to be constructed at the identified site (Thiers and Donovan 45). This lab uses the Sand Cone Method to verify the compaction of fill material and determine if the soil meet the required compaction with a design unit weight of 2,000 kg/m3. The aim of the experiment was to determine the dry unit weight, to ...

Abstract

A dual carriageway is proposed to be constructed in the town moving in the east-west direction. The dual carriage is intended to be eight-kilometer long looping around the northern part of the town. Cut and fill techniques are used where half of the road is cut to a maximum of six meters. Half of the road is supported by an embankment of six meters high. At the eastern and western ends of the road are of grade where the road joins other roads and at the middle where the cut sections meet the filled sections. The road has a ...

Introduction

In consolidation test of soil parameters of a sample, the settlement caused by applying an increased load to a soil sample is measured. These measurements involve the amount of soil that will decompress or compress on an application of a load.

The soil moisture content of the is first determined using a representative quantity and the mass of the remaining sample (Wd) which will be placed in the ...

1.0 Introduction

Multiple sclerosis (MS) is a neural degenerative condition involving the progressive degeneration of the myelin sheath (the protecting cover to the nerve fibres (axons)) around the nerve cell leading to a break down in transmission of nerve impulses. The impairment of the transmission results in loss of the body’s ability to control and coordinate muscle movement. The disease progresses through a complex and diverse symptoms making it challenging to diagnose, treat and manage. The symptoms of MS may range from gentle to severe weakness, impaired body movement, lack of ordered senses, uncontrolled bowel and bladder, damaged cognition, impaired vision and a variety ...
