Work-Related Upper Limb Symptoms in Hand-Intensive Health Care Occupations: A Cross-Sectional Study With a Health and Safety Perspective.

Background: Research with physical therapists reveals high rates of work-related musculoskeletal injuries, especially low back pain, with early career onset. Less focus has been given to upper limb disorders (ULDs) in these professionals, who frequently perform repetitive arm/hand and precision finger motions during work.

Objective: The objective was to estimate prevalence of body-site-specific upper limb (UL) symptoms and diagnosed ULDs in Irish chartered physical therapists, physiotherapists, and athletic therapists, with adjustment for leisure time injury, and document first onset of specific UL symptoms.

Relationships between soil and runoff phosphorus in small Alberta watersheds.

Field-scale relationships between soil test phosphorus (STP) and flow-weighted mean concentrations (FWMCs) of dissolved reactive phosphorus (DRP) and total phosphorus (TP) in runoff are essential for modeling phosphorus losses, but are lacking. The objectives of this study were (i) to determine the relationships between soil phosphorus (STP and degree of phosphorus saturation (DPS)) and runoff phosphorus (TP and DRP) from field-sized catchments under spring snowmelt and summer rainfall conditions, and (ii) to determine whether a variety of depths and spatial representations of STP improved the prediction of phosphorus losses. Runoff was monitored from eight field-scale microwatersheds (2 to 248 ha) for 3 yr.

Degree of phosphorus saturation thresholds in manure-amended soils of alberta.

The risk of P losses from agricultural land to surface and ground water generally increases as the degree of soil P saturation increases. A single-point soil P sorption index (PSI) was validated with adsorption isotherm data for determination of the P sorption status of Alberta soils. Soil P thresholds (change points) were then examined for two agricultural soils after eight annual applications of different rates of cattle manure and for three agricultural soils after one application of different rates of cattle manure.
