Technology Assessment
Technology assessment (TA, German: , French: ) is a scientific, interactive, and communicative process that aims to contribute to the formation of public and political opinion on societal aspects of science and technology. This is a means of assessing and rating the new technology from the time when it was first developed to the time when it is potentially accepted by the public and authorities for further use. In essence, TA could be defined as "a form of policy research that examines short- and long term consequences (for example, societal, economic, ethical, legal) of the application of technology." General description TA is the study and evaluation of new technologies. It is a way of trying to forecast and prepare for the upcoming technological advancements and their repercussions to the society, and then make decisions based on the judgments. It is based on the conviction that new developments within, and discoveries by, the scientific community are relevant for the worl ...

Data Build Tool
data build tool (dbt) is an open-source command line tool that helps analysts and engineers transform data in their warehouse more effectively. History It started at RJMetrics in 2016 as a solution to add basic transformation capabilities to Stitch (acquired by Talend in 2018). The earliest versions of dbt allowed analysts to contribute to the data transformation process following the best practices of software engineering. From the beginning, dbt was open source. In 2018, the dbt Labs team (then called Fishtown Analytics) released a commercial product on top of dbt Core. Funding In April 2020, dbt Labs announced its Series A led by Andreessen Horowitz. In November, dbt Labs announced its Series B led by Andreessen Horowitz and Sequoia. And in June 2021, dbt Labs raised its Series C led by Altimeter, Sequoia, and Andreessen Horowitz.

DBT (gene)
Lipoamide acyltransferase component of branched-chain alpha-keto acid dehydrogenase complex, mitochondrial is an enzyme that in humans is encoded by the ''DBT'' gene. The branched-chain alpha-keto acid dehydrogenase complex (BCKD) is an inner-mitochondrial enzyme complex involved in the breakdown of the branched-chain amino acids isoleucine, leucine, and valine. The BCKD complex is thought to be composed of a core of 24 transacylase (E2) subunits, and associated decarboxylase (E1), dehydrogenase (E3), and regulatory subunits. This gene encodes the transacylase (E2) subunit. Mutations in this gene result in maple syrup urine disease, type 2. Alternatively spliced transcript variants Alternative splicing, or alternative RNA splicing, or differential splicing, is an alternative splicing process during gene expression that allows a single gene to code for multiple proteins. In this process, particular exons of a gene may be ... have been described, but their biological validit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DBT Online Inc
DBT Online Inc., formerly known as Database Technologies, is a data mining company founded by Roy Brubaker and Hank Asher in 1992 in Las Vegas, Nevada, USA. It is today a subsidiary of US data aggregation group, ChoicePoint. DBT Online was formed as a public holding company by the merger of Database Technologies and Patlex in 1996. DBT Online bought Asher out for US$147 million in 1999. This followed the FBI and the Drug Enforcement Administration suspending their contracts with DBT Online following revelations that Asher had been involved but not charged with drug dealing in the Bahamas. The agencies were also concerned that DBT Online could potentially monitor targets of investigations. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

DBase
dBase (also stylized dBASE) was one of the first database management systems for microcomputers and the most successful in its day. The dBase system includes the core database engine, a query system, a forms engine, and a programming language that ties all of these components together. dBase's underlying file format, the file, is widely used in applications needing a simple format to store structured data. Originally released as Vulcan for PTDOS in 1978, the CP/M port caught the attention of Ashton-Tate in 1980. They licensed it and re-released it as dBASE II, and later ported it to IBM PC computers running DOS. On the PC platform, in particular, dBase became one of the best-selling software titles for a number of years. A major upgrade was released as dBase III, and ported to a wider variety of platforms, adding UNIX, and VMS. By the mid-1980s, Ashton-Tate was one of the "big three" software publishers in the early business software market, the others being Lotus Developmen ...

Design Basis Accident
A design-basis event (DBE) is a postulated event used to establish the acceptable performance requirements of the structures, systems, and components, such that a nuclear power plant can withstand the event and not endanger the health or safety of the plant operators or the wider public. Similar terms are design-basis accident (DBA) and maximum credible accident. Subtypes of DBEs are: * design-basis criticality: "A criticality accident that is the most severe design-basis accident of that type applicable to the area under consideration." * design-basis earthquake (DBE): "That earthquake for which the safety systems are designed to remain functional both during and after the event, thus assuring the ability to shut down and maintain a safe configuration." * design-basis explosion: "An explosion that is the most severe design-basis accident of that type applicable to the area under consideration." * design-basis fire: "A fire that is the most severe design-basis accident of this ty ...

Deutscher Bundestag
The Bundestag (, "Federal Diet") is the German federal parliament. It is the only federal representative body that is directly elected by the German people. It is comparable to the United States House of Representatives or the House of Commons of the United Kingdom. The Bundestag was established by Title III of the Basic Law for the Federal Republic of Germany (, ) in 1949 as one of the legislative bodies of Germany and thus it is the historical successor to the earlier Reichstag. The members of the Bundestag are representatives of the German people as a whole, are not bound by any orders or instructions and are only accountable to their electorate. The minimum legal number of members of the Bundestag (german: link=no, Mitglieder des Bundestages) is 598; however, due to the system of overhang and leveling seats the current 20th Bundestag has a total of 736 members, making it the largest Bundestag to date and the largest freely elected national parliamentary chamber in the w ...

Dibenzothiophene
Dibenzothiophene (DBT, diphenylene sulfide) is the organosulfur compound consisting of two benzene rings fused to a central thiophene ring. It is a colourless solid that is chemically somewhat similar to anthracene. This tricyclic heterocycle, and especially its alkyl substituted derivatives, occur widely in heavier fractions of petroleum. Synthesis and reactions Dibenzothiophene is prepared by the reaction of biphenyl with sulfur dichloride in the presence of aluminium chloride. Reduction with lithium results in scission of one C-S bond. With butyllithium, this heterocycle undergoes stepwise lithiation at the 4-position. S-oxidation with peroxides gives the sulfoxide In organic chemistry, a sulfoxide, also called a sulphoxide, is an organosulfur compound containing a sulfinyl () functional group attached to two carbon atoms. It is a polar functional group. Sulfoxides are oxidized derivatives of sulfides. E .... References {{Reflist Thiophenes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dibutyltryptamine
''N,N''-Dibutyltryptamine (DBT) is a psychedelic drug belonging to the tryptamine family. It is found either as its crystalline hydrochloride salt or as an oily or crystalline base. DBT was first synthesized by the chemist Alexander Shulgin and reported in his book '' TiHKAL (Tryptamines i Have Known And Loved)''. Shulgin did not test DBT himself, but reports a human dosage of "1 mg/kg i.m." being active, but less so than DMT or DET. This suggests that an active dosage of DBT will be in the 100 mg range. This compound has been sold as a "research chemical" and has been confirmed to be an active hallucinogen although somewhat weaker than other similar tryptamine derivatives. It produces a head-twitch response in mice. There are four symmetrical isomers of DBT which can be made, or ten isomers in total if unsymmetrical substitution is used. Of these only the n-butyl analogue DBT is known to be active in humans; the isobutyl, sec-butyl, and tert-butyl isomers DIBT, DSBT and ...

Digital Breast Tomosynthesis
Tomosynthesis, also digital tomosynthesis (DTS), is a method for performing high-resolution limited-angle tomography at radiation dose levels comparable with projectional radiography. It has been studied for a variety of clinical applications, including vascular imaging, dental imaging, orthopedic imaging, mammographic imaging, musculoskeletal imaging, and chest imaging. History The concept of tomosynthesis was derived from the work of Ziedses des Plantes, who developed methods of reconstructing an arbitrary number of planes from a set of projections. Though this idea was displaced by the advent of computed tomography, tomosynthesis later gained interest as a low-dose tomographic alternative to CT. Reconstruction Tomosynthesis reconstruction algorithms are similar to CT reconstructions, in that they are based on performing an inverse Radon transform. Due to partial data sampling with very few projections, approximation algorithms have to be used. Filtered back projection and iter ...
