Abstract The composite system of stone columns reinforced soil overlaid by granular mattress (GM) has been given more attention as a hybrid improvement technique. This work presents 3D finite element analyses using PLAXIS software for floating group constructed in deep soft clay deposit Port-Said Egypt. limited area loading was investigated conjunction with the key parameters, i.e., length, dia...

Molds and allergens are common indoor biocontaminants. The aims of this study were to assess the concentrations of common molds in indoor air and floor dust and the concentrations of house dust mite, cat and dog allergens in mattress dust in French dwellings, and to assess predictors of these concentrations. A sample of 150 houses in Brittany (western France) was investigated. Airborne Cladospo...

This study explores the hypothesis that a high degree of sustained muscle activity associated with a sub-optimal spinal orientation may compromise an individual's ability to relax or initiate sleep. Data from 22 participants who were considered to be part of a normal, back-pain-free population were used in these studies. Participants laid down on a mattress in a foetal position (i.e. on their s...

OBJECTIVE To compare whether differences exist between alternating pressure overlays and alternating pressure mattresses in the development of new pressure ulcers, healing of existing pressure ulcers, and patient acceptability. DESIGN Pragmatic, open, multicentre, randomised controlled trial. SETTING 11 hospitals in six NHS trusts. PARTICIPANTS 1972 people admitted to hospital as acute or...

The adaptive mechanisms that prevent edema of the lower limbs when standing involve the action of muscles pumping fluids against the force of gravity. The objective of the current study was to evaluate the interference of gravitational pressure on active exercises of lower limbs with lymphedema. A total of 24 male and 5 female patients with a mean age of 34.6 and lymphedema of the...

BACKGROUND Rupture of the subscapularis (SSC) tendon, isolated or combined, is rare, and the treatment modalities are controversial. The purpose of this study was to evaluate, by magnetic resonance imaging (MRI), the clinical outcomes and structural integrity of the SSC tendon after all-arthroscopic repair with single-row mattress suture for isolated or combined SSC tendon tears. METHODS This...

A universal concern of those in nursing care is the occurrence of decubitus ulcers. To minimize this problem foam overlays are routinely used on hospital beds throughout the country. This study was undertaken to develop laboratory testing procedures which will reliably predict the support characteristics of mattress overlays in clinical service. Initially, test methods based on constant load an...
