A feedback system to improve the quality of nutritional care.

Objective: The main objective of this study was to develop a feedback system that improves the translation of malnutrition performance data from the Dutch National Prevalence Measurement of Care Problems (LPZ) into relevant evidence- and practice-based interventions in care homes.

Methods: The process consisted of two stages. The first was the development of a feedback system.

Learners' perceptions of learners regarded as having a homosexual orientation in an independent secondary school environment.

In schools today discrimination based on sexual orientation takes place on a regular basis. This form of discrimination leads to aggression towards learners perceived to be homosexual, as well as towards those with a homosexual orientation. For more than 15 years South Africa has been a democratic country with laws that protect learners who have a homosexual orientation.

Water and electrolyte intake and output in conditioned Thoroughbred horses transported by road.

The objectives of this trial were to measure the water and electrolyte intake and loss, of horses during road transportation in relatively hot environmental conditions. Six mature, Thoroughbred horses in full training were used in a balanced crossover design. The horses were conditioned on a treadmill for 6 weeks before the start of the trial in order to simulate the type of horse that is transported most often over long distances in South Africa.

Integrative model for predicting thermal balance in exercising horses.

A theoretical integrative model was developed to determine the heat balance of horses working in a given environment. This model included the following parameters: metabolic heat gain, solar heat gain, evaporative heat loss due to sweating, respiratory tract heat loss, radiation from the body and heat gain or loss due to convection and conduction. The model developed in this study includes an unique approach for estimating heat loss via evaporation of sweat from the animal's skin surface.

Effect of three different warm-up regimens on heat balance and oxygen consumption of thoroughbred horses.

Horses were exercised at 105% of their maximal O2 uptake until fatigued after three different warm-up regimens (no warm-up, a light warm-up, and a warm-up until the central venous temperature was > 39.5 degrees C) to assess the effect of the warm-up on the various avenues of heat loss. Approximately 12.

Pyruvate kinase inhibition in the diagnosis of gliomas with an intermediate degree of malignancy.

The aim of the investigation was to see if the histological diagnosis of brain tumors showing an intermediate degree of malignancy can be improved by the measurement of L-alpha-alanine inhibition of pyruvate kinase isoenzymes. The inhibition of pyruvate kinase activity was measured in 51 gliomas with different grades of malignancy. It was confirmed that benign tumors have a low level of inhibition (less than 50%) and that the more malignant the tumor, the higher the level of inhibition became, reaching more than 75%.
