To the Editor: In a recent article from a prominent cardiological journal, the authors compared major adverse cardiac event rates between primary coronary angioplasty and thrombolytic therapy. They reported their results for the PCAT collaboration, but never explained what the acronym PCAT stood for. That surprised and disappointed me, because according to the International Committee of Medical...

Exercising women with menstrual disturbances frequently display a low resting metabolic rate (RMR) when RMR is expressed relative to body size or lean mass. However, normalizing RMR for body size or lean mass does not account for potential differences in the size of tissue compartments with varying metabolic activities. To explore whether the apparent RMR suppression in women with exercise-asso...

The effects of dehulling and micronization (infrared heating) on the nutritive value of three cultivars (Impala, Radley, and Sirius) of peas (Pisum sativum) varying in coat color for broiler chickens were studied. Dehulling increased (P < or = 0.05) protein and starch contents and decreased (P < or = 0.05) fiber content of peas. Also, the concentrations of most amino acids slightly increased (P...

The effect of phytase on the performance, AMEn, and the ileal digestibility of N and amino acids was investigated in a 15-d trial using day-old male broilers with diets that were low in Ca (0.9% for control and 0.79% for phytase treatment) and available P (AP; 0.45% for control and 0.35% for phytase treatment). The assayed dietary phytase activity of crumble diet was 1,149 phytase unit (FTU)/kg...

This paper is focused on the solution quality and computing time requirements of heuristic methods for cost-oriented assembly line balancing. It is based on a recent paper (Amen, International Journal of Production Economics 68 (2000), which describes in detail the solution process of existent and two new heuristics. After a short review of the historic origin and the wideness of assembly line ...

In the far-away homeland of Transkei there is poverty, malnutrition, and only the beginnings of economic development. But there is also a spar of hope and realism: its name is Kwazup -from kwa zondle uphile, which literally translated means "to feed yourself to be healthy." On a landscape of rondavels, mealie fields, and grazing cattle, where families struggle in the wet season to grow enough f...
