Social Support and its Relationship to Quality of Life among Amputation Cases

Background: Social support is an important source of psychological and social support that a disabled needs in his daily life, as its size and level of satisfaction affect how the patient perceives the various stresses of life. Because of the neglect of amputations, it is necessary to study social support and its impact on their quality of life. Objectives: The purpose of this study is to inve...

Numerical modeling of tunneling induced ground deformation and its control

Tunnelling through cities underlain by soft soil, commonly associated with soil movement around the tunnels and subsequent surface settlement. The predication of ground movement during the tunnelling and optimum support pressure could be based on analytical, empirical or the numerical methods. The commonly used Earth pressure balance (EPB) tunneling machines, uses the excavated soil in a pressu...

Crop management effect on chemical and biological properties of soil

This study was aimed at evaluating the effect of crop rotation and various tillage systems onthe chemical and biological properties of soil in the years 2013-2015. The first order factorincluded cropping systems: a) crop rotation (pea – winter wheat – spring wheat) and b)monoculture of winter wheat, whereas the second order factor were tillage systems:1) conventional (CT), 2) reduced (RT) and 3...

Study of Loose Soil Layer Effects on Excavations Supported by Steel Sheet Pile Walls – A Numerical Study

Abstract Steel sheet pile walls are being widely used in civil engineering projects for support systems. Soil is not uniform in depth, sometimes may be exit loose or soft soil layer in various depth. This issue can cause different effects on ground surface displacements, forces and moments acting on sheet piles and struts during excavation procedure, compared with status that soil is uniform...
