PURPOSE Although knee arthroscopy is described as minimally invasive, return to activity has been poorly quantitated. Our purpose is to test the hypothesis that most patients return to unrestricted activity within 4 weeks after knee arthroscopy. METHODS After prospective power analysis, 72 consecutive patients who underwent arthroscopic knee partial medial meniscectomy, partial lateral menisc...

Fresh mushroom compost is a byproduct of the edible mushroom (Agaricus bisporus) industry and represents the composted growing substrate that remains after a crop has been harvested to completion. Thirty samples were obtained from commercial mushroom farms in southeastern Pennsylvania and sent to a laboratory for analysis to determine plant nutrient content, bulk density, and particle size dist...

We present an optimization model for the yard allocation process in an automotive transshipment terminal. The cars arrive and depart by ships in large batches and the yard planners have to dynamically assign incoming cars to parking rows. The integer linear programming model has been implemented in a commercial solver (CPLEX). We will present at the conference the model, the CPLEX computational...

BACKGROUND: Selenium is now recognized as essential trace element for ruminants. OBJECTIVES: Studying the effect of different levels of selcote ultra fertilizer and farm yard manure on the concentration of selenium in alfalfa in order to achieve optimum concentration of selenium in this plant. METHODS: The experiment was factorial based on ra...

PURPOSE This study adds to the previous work in the field of sport-specific fitness testing by evaluating a tennis-specific agility test called "the 20-yard shuttle test". The aim of the study was to evaluate the test-retest reliability, the inter-rater reliability, and the criterion-related validity of the 20-yard shuttle test on competitive junior tennis players. PARTICIPANTS AND METHODS To...

The Service Allocation Problem (SAP) is a tactical problem arising in the yard management of a container transshipment terminal. The objective is the minimization of the container rehandling operations inside the yard. This study of the SAP was undertaken for the Gioia Tauro port which is located in Italy and is the main hub terminal for container traffic in the Mediterranean Sea. The SAP can b...

The purposes of this study were to examine perceptions of places to play and be physically active among children from two different urban neighborhoods, and evaluate these perceptions for age-related developmental differences. One hundred and sixty-eight children from grades K-6 (aged 6-12 years old) completed mental maps depicting places where they could play and be physically active. The chil...

BACKGROUND The horseracing training industry has largely been ignored in terms of active occupational health research. AIMS To provide baseline statistics on the specific nature and type of accidents that occurred in English horseracing stables during 2008. METHODS All 716 training yards/stables registered with the British Horseracing Authority were contacted in April/May 2009 to complete t...
