The tear turnover and tear clearance tests – a review [PDF]

open access: yesExpert Review of Medical Devices, 2018
Introduction. The aim is to provide a summary of methods available for the assessment of tear turnover and tear clearance rates. The review defines tear clearance and tear turnover and describes their implication for ocular surface health. Additionally, it describes main types of techniques for measuring tear turnover, including fluorescein tear ...

Meniscal tears

open access: yesOpen Access Journal of Sports Medicine, 2010
The menisci are two semilunar-shaped fibrocartilagenous structures, which are interposed between the femoral condyles and tibial plateaux. They have an important role in knee function. Long-term follow-up studies showed that virtually all meniscectomized knees develop arthritic changes with time.

Modification of Constrained Rod Casting Mold for New Hot Tearing Measurement [PDF]

open access: yesArchives of Metallurgy and Materials, 2018
Hot tearing severity was evaluated in this experiment by introducing a new apparatus called Constrained Rod Casting Modified Horizontal (CRCM-Horizontal). Six constraint bars with different lengths can produce hot tearing on the cast sample.

Zinc in Tears

open access: yesOphthalmic Research, 1991
The tear and serum zinc (Zn) levels were determined simultaneously by atomic absorption spectrophotometry in 11 healthy subjects. The mean tear Zn level was found to be 1.537 +/- 0.146 (SEM) ppm while the mean serum Zn level was found to be 1.03 +/- 0.046 (SEM) ppm.

Population and species neighbor identity impact trait–trait relationships and plant performance

open access: yesPopulation Ecology, EarlyView.
We evaluated how populations and species identity influence plant performance and trait outcomes in mixtures, and assessed trait variation among populations of two forb species native to the western United States (Dieteria canescens and Heterotheca villosa) following three interaction treatments (single‐population monoculture, two‐population mixture ...
