Failure Analysis of the Split-D Test Method
1977The Split-D test is used to determine unidirectional tensile strength of filament wound composites, but it has a known stress concentration in the ring near the D edge. A finite element stress analysis and a statistical strength theory are used to assess the influence of the stress concentration on the ultimate strengths calculated for the composites ...

The rise and rise of vitamin D testing
BMJ, 2012Moynihan and colleagues’ report highlights the increasing trend for overdiagnosis, particularly of endocrine disorders.1 Similar concerns exist for overdiagnosis and overtreatment of vitamin D deficiency.2 3 Currently, the appropriate timing and frequency of testing for the diagnosis of vitamin D deficiency is unclear. The cost of testing in …

Pathology Consultation on Vitamin D Testing
American Journal of Clinical Pathology, 2011The last decade has seen a substantial increase in clinical interest in vitamin D deficiency and of laboratory testing for vitamin D status. Many clinical laboratories in the United States have seen requests for vitamin D testing increase 100% or more in the last 5 years.

Prevalence of biochemical osteomalacia in adults undergoing vitamin D testing
Clinical Endocrinology, 2021AbstractObjectiveProlonged severe vitamin D deficiency can cause osteomalacia, but the 25‐hydroxyvitamin D (25OHD) concentration below which this occurs is unknown. We investigated the prevalence of biochemical osteomalacia in adults with a measurement of 25OHD.Design, Measurement, and Patients25OHD results between 1/1/2009 and 15/6/2020 were obtained ...

Vitamin D testing: advantages and limits of the current assays
European Journal of Clinical Nutrition, 2020Vitamin D deficiency and insufficiency has become a pandemic health problem with a consequent increase of requests for determining circulating levels of 25-hydroxyvitamin D [25(OH)D]. However, the analytical performance of these immunoassays, including radioimmunoassay and ELISA, is highly variable, and even mass spectrometric methods, which nowadays ...

Journal of the American Optometric Association, 1983
An objective indirect method of evaluating saccadic performance is of interest to optometrists and non optometrists. A sample of 1202 children ages six to fourteen were screened using the New York State Optometric Association Vision Screening Battery. The NYSOA K-D Test was part of that battery.

The CIGRE benchmark model consists of weak rectifier and inverter a.c. systems resonant at the second harmonic and a d.c. system resonant at the fundamental frequency. Both a.c. systems are balanced and connected in star-ground. The HVDC link is a 12-pulse monopolar configuration with the converter transformers connected star-ground/star and star ...

Targeted vitamin D testing recommended in Australasia
The Lancet Diabetes & Endocrinology, 2013Vitamin D testing should not be done by routine screening but should be used only in people with clear signs of defi ciency, or who are at risk for defi ciency, for whom treatment is likely to be of benefi t, according to a position statement from the Royal College of Pathologists of Australasia.
