Database Description
In computing, a database is an organized collection of data or a type of data store based on the use of a database management system (DBMS), the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS additionally encompasses the core facilities provided to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a database system. Often the term "database" is also used loosely to refer to any of the DBMS, the database system or an application associated with the database. Before digital storage and retrieval of data have become widespread, index cards were used for data storage in a wide range of applications and environments: in the home to record and store recipes, shopping lists, contact information and other organizational data; in business to record presentation notes, project research and notes, and contact information; in schools as flash cards o ...

Deep Borehole Disposal
Deep borehole disposal (DBD) is the concept of disposing high-level radioactive waste from nuclear reactors in extremely deep boreholes instead of in more traditional deep geological repositories that are excavated like mines. Deep borehole disposal seeks to place the waste as much as beneath the surface of the Earth and relies primarily on the thickness of the natural geological barrier to safely isolate the waste from the biosphere for a very long period of time so that it should not pose a threat to humans and the environment. The concept was originally developed in the 1970s, but in 2014, a proposal for a first experimental borehole was proposed by a consortium headed by Sandia National Laboratories. The waste would be put into the lower mile of such a hole, within crystalline rock to isolate it from the environment.Conca, James."DOE Tries To Change The Rules On Nuclear Waste Disposal" ''Forbes'' (January 21, 2016). The upper two miles of the borehole would be filled with pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Defective By Design
Defective by Design (DBD) is a grassroots anti-digital rights management (DRM) initiative by the Free Software Foundation (FSF) and CivicActions. Launched in 2006, DBD believes that DRM (which they call "digital ''restrictions'' management") makes technology deliberately defective, negatively affects digital freedoms, and is "a threat to innovation in media, the privacy of readers, and freedom for computer users." The initiative regularly campaigns against the use of DRM by the media industry and software industry to increase awareness of the anti-DRM movement and pressure industries into no longer using DRM. They are known for their use of hazmat suits in their demonstrations. DBD represents one of the first efforts of the FSF to find common cause with mainstream social activists and encourage free software advocates to become socially involved. As of late 2006, the campaign was claiming over 12,000 registered members. Position According to their website, DBD believes th ...

Dielectric Barrier Discharge
Dielectric-barrier discharge (DBD) is the electrical discharge between two electrodes separated by an insulating dielectric barrier. Originally called silent (inaudible) discharge and also known as ozone production discharge or partial discharge, it was first reported by Ernst Werner von Siemens in 1857.Kogelschatz, Ulrich, Baldur Eliasson, and Walter EgliFrom ozone generators to flat television screens: history and future potential of dielectric-barrier discharges Pure Applied Chemistry, Vol. 71, No. 10, pp. 1819–1828, 1999. Retrieved on 5 August 2007. Process The process normally uses high voltage alternating current, ranging from lower RF to microwave frequencies. However, other methods were developed to extend the frequency range all the way down to the DC. One method was to use a high resistivity layer to cover one of the electrodes. This is known as the resistive barrier discharge.M. Laroussi, I. Alexeff, J. P. Richardson, and F. F. Dyer " The Resistive Barrier D ...

DNA-binding Domain
A DNA-binding domain (DBD) is an independently folded protein domain that contains at least one structural motif that recognizes double- or single-stranded DNA. A DBD can recognize a specific DNA sequence (a recognition sequence) or have a general affinity to DNA. Some DNA-binding domains may also include nucleic acids in their folded structure. Function One or more DNA-binding domains are often part of a larger protein consisting of further protein domains with differing function. The extra domains often regulate the activity of the DNA-binding domain. The function of DNA binding is either structural or involves transcription regulation, with the two roles sometimes overlapping. DNA-binding domains with functions involving DNA structure have biological roles in DNA replication, repair, storage, and modification, such as methylation. Many proteins involved in the regulation of gene expression contain DNA-binding domains. For example, proteins that regulate transcription ...

Perl DBI
In computing, the Perl DBI (Perl Database Interface) offers a standardized way for programmers using the Perl programming language to embed database communication within their programs. The latest DBI module for Perl from CPAN can run on a range of operating systems. History In September 1992, Buzz Moschetti, creator of interperl, observed that several bespoke compiled extensions of perl (at the time, perl version 4 or more commonly perl4) featuring connectivity to popular SQL-based databases had emerged, namely Interbase, Informix, Oracle, and Sybase. He engaged the authors of these bespoke versions with the idea of creating a common interface layer to the databases separate from the specifics of the underlying implementations. Tim Bunce took the lead and began specifying what would become the DBI module in 1994 upon the release of perl5 which eliminated the need for bespoke compilation in favor of dynamic, invocation time loading of libraries (modules). the Perl communi ...

DB(D)
A-weighting is a form of frequency weighting and the most commonly used of a family of curves defined in the International standard IEC 61672:2003 and various national standards relating to the measurement of sound pressure level. A-weighting is applied to instrument-measured sound levels in an effort to account for the relative loudness perceived by the human ear, as the ear is less sensitive to low audio frequencies. It is employed by arithmetically adding a table of values, listed by octave or third-octave bands, to the measured sound pressure levels in dB. The resulting octave band measurements are usually added (logarithmic method) to provide a single A-weighted value describing the sound; the units are written as dB(A). Other weighting sets of values – B, C, D and now Z – are discussed below. The curves were originally defined for use at different average sound levels, but A-weighting, though originally intended only for the measurement of low-level sounds (around ...

Beating Heart Cadaver
A beating heart cadaver is a body that is pronounced dead in all medical and legal definitions, connected to a medical ventilator, and retains cardio-pulmonary functions. This keeps the organs of the body, including the heart, functioning and alive. Roach, Mary. ''Stiff: the Curious Lives of Human Cadavers''. New York: W.W. Norton &, 2003. Print. As a result, the period of time in which the organs may be used for transplantation is extended. The heart contains pacemaker cells that will cause it to continue beating even when a patient is brain-dead. Other organs in the body do not have this capability and need the brain to be functioning to send signals to the organs to carry out their functions. A beating heart cadaver requires a ventilator to provide oxygen to its blood, but the heart will continue to beat on its own even in the absence of brain activity. This allows organs to be preserved for a longer period of time in the case of a transplant or donation. A small number of cas ...
