Large contemporary swine-production systems routinely turn to water delivery systems as a method for administering approved therapeutic agents when circumstances call for mass treatment of entire pig populations. Water medications are used for reasons ranging from the relative ease of the method compared to injectables, to the decreased likelihood of needle-stick injuries and broken needles fou...

We studied the mathematical relations between species abundance distributions (SADs) and species-area relationships (SARs) and found that a power-law SAR can be generally derived from a power-law SAD without a special assumption such as the “canonical hypothesis”. In the present analysis, an SAR-exponent is obtained as a function of an SAD-exponent for a finite number of species. We also studie...

In 2007 George E. Andrews and Peter Paule [1] introduced a new class of combinatorial objects called broken k-diamonds. Their generating functions connect to modular forms and give rise to a variety of partition congruences. In 2008 Song Heng Chan proved the first infinite family of congruences when k = 2. In this note we present two non-standard infinite families of broken 2-diamond congruence...

In many large environmental datasets redundant variables can be discarded without the loss of extra variation. Principal components analysis can be used to select those variables that contain the most information. Using an environmental dataset consisting of 36 meteorological variables spanning 37 years, four methods of variable selection are examined along with di€erent criteria levels for dec...

The task and design requirements for a vision system for manipulator position sensing in a telerobotic system are described. Model-based analysis-by-synthesis techniques offer generally applicable methods with the potential to meet the system's requirement for accurate , fast and reliable results. Edge-based chamfer matching allows eecient computation of a measure, E, of the local diierence bet...

Mycorrhizae regulate elemental and energy flows in terrestrial ecosystems. We understand much of how mycorrhizae work, but integrating all possible mechanisms into a whole has proven elusive. Multiple evolutionary events and the long evolutionary history mean that different plants and fungi bring independent characteristics to the symbiosis. This variety results in extensive physiological varia...

OBJECTIVES This study investigated the knowledge, awareness and practices of health care workers towards universal precautions at the University Hospital of the West Indies. The study also examined the prevalence of injuries experienced by health care workers, as well as incidence of accidents and compliance with post-exposure prophylaxis. MATERIALS AND METHODS A cross sectional survey was co...
