translucency

The quality of being able to see through a material whereby the distant image is hazy or foggy. The terms "translucent" and "transparent" are often used synonymously, but they are not the same. A translucent area in an image would be like looking through frosted or smoked glass to the underlying background. A transparent area would be like looking through clear glass.

Not Well Supported
True translucency is not supported in many graphics formats as an attribute of the image. Although the visual effect of translucency can always be simulated in an image by using an image editing program, the actual translucent area is opaque, and the underlying background does not show through.

Translucency is an advanced technique; for example, Adobe's PostScript and HP's PCL language do not support translucency; however, Adobe's PDF, which came later, does support it. Images formatted with true translucency that are printed in PostScript and PCL are flattened into opaque images that tend to have visual artifacts. See alpha blending.


Translucent Borders
See-through, translucent window borders were one of the eye-candy features in the Aero interface introduced in Windows Vista. Articles about Aero erroneously refer to "transparent windows" more than they do "translucent windows."

Translucency

The quality of a material that transmits light sufficiently diffused to eliminate any perception of distinct images beyond.

Increased nuchal translucency origins from abnormal lymphatic development and is independent of the presence of a cardiac defect.
At the time, no reliable data was available for multiple pregnancies and adjustment of data was considered unreliable in predicting fetal risk and first trimester nuchal translucency was considered to provide the only test for these pregnancies.
Extremely large nuchal translucency measurement predicts adverse pregnancy outcome.
Additionally, the difference between crown/tooth color on white and black background was calculated as the translucency parameter (TP), at incisal, body, and cervical part, respectively, with TP = [{[([L*.sub.B] - [L*.sub.W]).sup.2] + [([a*.sub.B] - [a*.sub.W]).sup.2] + [([b*.sub.B] - [b*.sub.W]).sup.2]}.sup.1/2].
The 2 groups still recommend conventional first- and second-trimester screening by serum chemical biomarkers and nuchal translucency as the first-line approach for low-risk women who want to pursue aneuploidy screening; however, they also recommend that the risks and benefits of cfDNA should be discussed with all patients.
Findings suggesting a diagnosis of CdLS in the prenatal period are increased nuchal translucency in the first trimester, symmetrical intrauterine developmental restriction (SIDR), significant defects in the upper extremities, and a dysmorphic facial appearance.
Crown rump length and Nuchal translucency are measured during the scan and in combination with maternal biochemistry BHcG and PAPP-A, used for aneuploidy screening as per standard protocols.
The chromosomal marker for nuchal translucency was chosen because it has become the most interesting marker described in the last ten years, it is easy to observe, can be studied with any type of ultrasound scanner and its relation with chromosomal abnormalities and fetal welfare is well understood (Bonilla & Machado, 2010).
According to Dr Ramanathan, “This new method of risk assessment has resulted in a shift to first trimester diagnostic testing by way of chorionic villus sampling (CVS) in the high risk group of women identified by screening with nuchal translucency and serum biochemistry, and also far less diagnostic testing, which itself carries a risk of miscarriage.

A spokesperson for the Betsi Cadwaladr University Health Board said during this scan, if possible, a measurement of the small space at the back of the baby's neck is made (referred to as Nuchal Translucency) and a blood test is taken.
In her work she explores the translucency of porcelain, when for instance layering coloured and white porcelain and deeply carving the surface, yet she also works with porcelain's material presence and it is this quality that probably resonates with Japanese and Korean audiences, for whom the translucency of porcelain (traditionally) has not been its primary aesthetic quality.
