One of the most fundamental decisions when designing a mold for the plastics thermoforming process is whether to use a plug (male) mold or a cavity (female) mold design. This critical decision is often brushed over in the literature yet has the greatest single impact on part wall thickness and wall thickness variation. Other considerations when deciding on this fundamental design concept includ...

OBJECTIVES The purpose of this study was to determine the mathematical relationship between left ventricular ejection fraction and global myocardial strain. A reduction in myocardial strain would be expected to cause a fall in ejection fraction. However, there is abundant evidence that abnormalities of myocardial strain can occur with a normal ejection fraction. Explanations such as a compensat...

Using transmission electron microscopy, we studied the presence of melanin and cell wall thickness of clinical isolates of Sporothrix schenckii obtained from cats, dogs and humans as compared to reference strains. We detected differences regarding presence of the melanin among the clinical isolates of S. schenckii and a correlation between presence of melanin and cell wall thickness.
