DST

(1) (DeSTination) Contrast with SRC, which is an abbreviation of "source."

(2) (Digital Signal Trust Company, Salt Lake City, UT, www.digsigtrust.com) An organization that sets up and manages PKI systems for companies and industry groups. Using third-party software, it serves as a certification authority (CA), manages the repository and provides a secure location for the private keys. Founded in 1996, Utah-based DST was the first licensed CA in the U.S. and the first PKI service organization. Utah was the first state in the U.S. to pass digital signature legislation.

In 2002, DST was acquired by Identrus LLC (www.identrus.com), a global leader in digital trust services and secure e-commerce. See PKI.

(3) (Data Storage Technology) A high-capacity magnetic tape technology from Ampex that is based on the digital composite D2 format for the broadcasting industry. It uses the same 19mm, helical scan transport, but provides higher capacities with Ampex's proprietary Data D-2 (DD2) format. DST cartridges range from 50 to 330GB and are suited for uncompressed digital video (movies, commercials, etc.) and high-resolution images as well as general data backup for huge databases. Ampex's Data Instrumentation Systems (DIS) tape technology is a counterpart line that provides optional modes and interfaces for data acquisition devices. See magnetic tape.


DST Tape Storage
DST is not exactly for home computer use. The large 330GB tape cassette, which is as big as a laptop computer, could back up the entire neighborhood. The 4mm DAT cassette is shown for size comparison.

Previously we reported that the rapid effect of BPA on the contractility of female cardiac myocytes is characterized by a nonmonotonic dose response (Belcher et al.
Another reason for concern, especially for parents, may be because some animal studies report effects in fetuses and newborns exposed to BPA.
Researchers found evidence of significant adverse effects in mammary glands, ovaries, brain, uterus, lung and heart tissues in BPA exposed fetus when compared to fetuses not exposed to BPA.
These great results are a reflection of the BPA Quality mission statement .
The revamped website includes new sections that provide basic information about BPA, information on the latest scientific research and health effects, and an overview of the benefits and applications of BPA:
The FDA ruling states that more evidence of harm needs to be shown, yet the evidence linking BPA to health conditions is there.
Laboratory tests commissioned by the non-profit Environmental Working Group (EWG) and carried out by the University of Missouri Division of Biological Sciences Laboratory in 2010 found high levels of BPA on 40 percent of receipts sampled from major U.
The results: several hours after lunch, BPA levels in the participants' urine were 12 times higher after the canned than after the fresh soup.
We believe there is enough (information) to warrant caution so we don't have to ingest BPA and we ought to start mitigating these exposures" says Urvashi Rangan, PhD, director of technical policy at Consumer Reports.
In three separate studies last year, conducted all over the world, researchers discovered BPA in cash register and ATM receipts.
Researchers note that some studies have shown adverse effects associated with exposure to BPA at lower doses.
