Center For Defense Information
The Center for Defense Information (CDI) is a nonprofit, nonpartisan organization based in Washington, D.C. It specialized in analyzing and advising on military matters. History The Center for Defense Information was founded in 1971 by an independent group of retired military officers including Adm. Gene La Rocque and Adm. Eugene Carroll. In 2005, the Center for Defense Information expanded by creating the Straus Military Reform Project for the purpose of promoting military reform in the Pentagon and Congress. Winslow T. Wheeler, a former Capitol Hill staffer and General Accounting Office assistant director, directs the Straus Military Reform Project at CDI. The Project was launched by a matching grant from Philip A. Straus Jr. Straus and his family have long supported activities at CDI and continue to be major supporters of the Project's endeavors. In May 2012, CDI joined the Project on Government Oversight. After the 2008 United States elections, CDI released ''America’s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CREST Depositary Interest
CREST is a UK-based central securities depository that holds UK equities and UK gilts, as well as Irish equities and other international securities. It was named after its securities settlement system, CREST, and has been owned and operated by Euroclear since 2002. The name CREST stands for Certificateless Registry for Electronic Share Transfer. CREST allows shareholders and bondholders to hold assets in a dematerialised, i.e. electronic form, rather than holding physical share certificates. CREST also serves a number of other important functions, such as assisting in the payments of dividends to shareholders. It is also an "electronic trade confirmation system" ("ETC") (using Trax). When parties to a transaction make a deal, they both electronically confirm their sides of the transaction via electronic transfer. Both parties are required to submit confirmation details to Crest. In the event that transaction details do not match, CREST will highlight the issues and ensure that t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capacitor Discharge Ignition
Capacitor discharge ignition (CDI) or thyristor ignition is a type of automotive electronic ignition system which is widely used in outboard motors, motorcycles, lawn mowers, chainsaws, small engines, turbine-powered aircraft, and some cars. It was originally developed to overcome the long charging times associated with high inductance coils used in inductive discharge ignition (IDI) systems, making the ignition system more suitable for high engine speeds (for small engines, racing engines and rotary engines). The capacitive-discharge ignition uses capacitor discharge current to the coil to fire the spark plugs. History Nikola Tesla The history of the capacitor discharge ignition system can be traced back to the 1890s when it is believed that Nikola Tesla was the first to propose such an ignition system. In first filed February 17, 1897, Tesla writes 'Any suitable moving portion of the apparatus is caused to mechanically control the charging of a condenser and its discharge ...

Color Doppler
Doppler ultrasonography is medical ultrasonography that employs the Doppler effect to perform imaging of the movement of tissues and body fluids (usually blood), and their relative velocity to the probe. By calculating the frequency shift of a particular sample volume, for example, flow in an artery or a jet of blood flow over a heart valve, its speed and direction can be determined and visualized. Duplex ultrasonography sometimes refers to Doppler ultrasonography or spectral Doppler ultrasonography. Doppler ultrasonography consists of two components: brightness mode (B-mode) showing anatomy of the organs, and Doppler mode (showing blood flow) superimposed on the B-mode. Meanwhile, spectral Doppler ultrasonography consists of three components: B-mode, Doppler mode, and spectral waveform displayed at the lower half of the image. Therefore, "duplex ultrasonography" is a misnomer for spectral Doppler ultrasonography, and more exact name should be "triplex ultrasonography". This is ...

Current Density Imaging
Current density imaging (CDI) is an extension of magnetic resonance imaging (MRI), developed at the University of Toronto. It employs two techniques for spatially mapping electric current pathways through tissue: * LF-CDI, low-frequency CDI, the original implementation developed at the University of Toronto. In this technique, low frequency (LF) electric currents are injected into the tissue. These currents generate magnetic fields, which are then measured using MRI techniques. The current pathways are then computed and spatially mapped. * RF-CDI, radio frequency CDI, a rotating frame of reference version of LF-CDI. This allows measurement of a single component of current density, without requiring subject rotation. The high frequency current that is injected into tissue also does not cause the muscle twitching often encountered using LF-CDI, allowing in-vivo measurements on human subjects. See also *Magnetic resonance imaging Magnetic resonance imaging (MRI) is a medical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coherent Diffraction Imaging
Coherent diffractive imaging (CDI) is a "lensless" technique for 2D or 3D reconstruction of the image of nanoscale structures such as nanotubes, nanocrystals, porous nanocrystalline layers, defects, potentially proteins, and more. In CDI, a highly coherent beam of X-rays, electrons or other wavelike particle or photon is incident on an object. The beam scattered by the object produces a diffraction pattern downstream which is then collected by a detector. This recorded pattern is then used to reconstruct an image via an iterative feedback algorithm. Effectively, the objective lens in a typical microscope is replaced with software to convert from the reciprocal space diffraction pattern into a real space image. The advantage in using no lenses is that the final image is aberration–free and so resolution is only diffraction and dose limited (dependent on wavelength, aperture size and exposure). Applying a simple inverse Fourier transform to information with only intensities is i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CD-i
The Compact Disc-Interactive (CD-I, later CD-i) is a Digital media, digital optical disc data storage device, data storage format that was mostly developed and marketed by Dutch company Philips. It was created as an extension of Compact Disc Digital Audio, CDDA and CD-ROM and specified in the ''Rainbow Books, Green Book'', co-developed by Philips and Sony, to combine audio, text and graphics. The two companies initially expected to impact the education/training, point of sale, and home entertainment industries, but CD-i eventually became best known for its video games. CD-i media physically have the same dimensions as CD, but with up to of digital data storage, including up to 72 minutes of full motion video. CD-i players were usually standalone boxes that connect to a standard television; some less common setups included integrated CD-i television sets and expansion modules for personal computers. Most players were created by Philips; the format was licensed by Philips and Mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclin-dependent Kinase Inhibitor Protein
A cyclin-dependent kinase inhibitor protein is a protein which inhibits the enzyme cyclin-dependent kinase (CDK). Several function as tumor suppressor proteins. Cell cycle progression is delayed or stopped by cyclin-dependent kinase inhibitors, abbreviated CDIs, CKIs or CDKIs. CDIs are involved in cell cycle restriction point, arrest at the G1 phase, G1 phase. Seven cyclin-dependent kinase inhibitor proteins have thus far been identified. They are named by the small letter "p" followed by their molecular weight in kilodaltons. They are p15, p16, p18, p19, p21, p27, and p57.

Contact-dependent Growth Inhibition
Contact-dependent growth inhibition (CDI) is a phenomenon where a bacterial cell may deliver a polymorphic toxin molecule into neighbouring bacterial cells upon direct cell-cell contact, causing growth arrest or cell death. Discovery CDI is now a blanket term to describe interbacterial competition that relies on direct cell-cell contact in bacteria. However, the phenomenon was first discovered in 2005 in the isolate EC93 of ''Escherichia coli'' found in rat intestine, and, in this case, was mediated by a Type V secretion system. This isolate dominated the rat's gut flora and appeared to be particularly good at outcompeting lab strains of ''E. coli'' when grown in co-culture''.'' The novel part of this discovery was the fact that the inhibitory effects of the isolated ''E. coli'' appeared to require direct cell-cell contact. Before CDI was discovered in this isolate, the only systems known to mediate direct interbacterial competition by intoxication were toxins secreted into the ...

Combined Drug Intoxication
Combined drug intoxication (CDI), or multiple drug intake (MDI), is a cause of death by drug overdose from poly drug use, often implicated in polysubstance dependence. Deaths by combined drug intoxication are relatively rare (one in several million). In 2004, there were 3,800 deaths in the US resulting from a fatal medication error involving alcohol, while in 1983 there were less than 100 such deaths. It is more of a risk for older patients. Risk factors People who engage in polypharmacy and other hypochondriac behaviors are at an elevated risk of death from CDI. Other dangers of combining drugs include "brain damage, heart problems, seizures, stomach bleeding, liver damage/ liver failure, heatstroke, coma, suppressed breathing, and respiratory failure", along with many other complications. Disorders like depression and anxiety can also stem from polydrug use. Elderly people are at the highest risk of CDI, because of having many age-related health problems requiring many medi ...

Clostridioides Difficile Infection
''Clostridioides difficile'' infection (CDI or C-diff), also known as ''Clostridium difficile'' infection, is a symptomatic infection due to the bacterial spores, spore-forming bacterium ''Clostridioides difficile''. Symptoms include watery diarrhea, fever, nausea, and abdominal pain. It makes up about 20% of cases of antibiotic-associated diarrhea. Antibiotics can contribute to detrimental changes in gut microbiota; specifically, they decrease short-chain fatty acid absorption which results in osmotic, or watery, diarrhea. Complications may include colitis#Infectious, pseudomembranous colitis, toxic megacolon, perforation of the colon, and sepsis. ''Clostridioides difficile'' infection is spread by bacterial spores found within feces. Surfaces may become contaminated with the spores with further spread occurring via the hands of healthcare workers. Risk factors for infection include antibiotic or proton pump inhibitor use, hospitalization, other health problems, and older a ...
