ECM Records
ECM (Edition of Contemporary Music) is an independent record label founded by Karl Egger, Manfred Eicher and Manfred Scheffner in Munich in 1969. While ECM is best known for jazz music, the label has released a variety of recordings, and ECM's artists often refuse to acknowledge boundaries between genres. ECM's motto is "the most beautiful sound next to silence", taken from a 1971 review of ECM releases in '' Coda'', a Canadian jazz magazine. ECM has been distributed in the U.S. by Warner Bros. Records, PolyGram Records, BMG, and, since 1999, Universal Music, the successor of PolyGram, worldwide. Its album covers were profiled in two books: ''Sleeves of Desire'' and ''Windfall Light'', both published by Lars Müller. History The first ECM release produced by Manfred Scheffner was pianist Mal Waldron's 1969 recording '' Free at Last''. The label went on to release recordings by many prominent jazz musicians, including Paul Bley, Keith Jarrett, Jan Garbarek, Pat Metheny, Gary ...

Enterprise Content Management
Enterprise content management (ECM) extends the concept of content management by adding a timeline for each content item and, possibly, enforcing processes for its creation, approval, and distribution. Systems using ECM generally provide a secure repository for managed items, analog or digital. They also include one (or more) methods for importing content to manage new items, and several presentation methods to make items available for use. Although ECM content may be protected by digital rights management (DRM), it is not required. ECM is distinguished from general content management by its cognizance of the processes and procedures of the enterprise for which it is created. Definitions * Late 2005: The technology was used to capture, manage, store, preserve, and deliver content and documents related to organizational processes * Early 2006: ECM tools and strategies allowed the management of an organization's unstructured information, wherever that information exists. * Early 2 ...

Extracellular Matrix
In biology, the extracellular matrix (ECM), also called intercellular matrix (ICM), is a network consisting of extracellular macromolecules and minerals, such as collagen, enzymes, glycoproteins and hydroxyapatite that provide structural and biochemical support to surrounding cells. Because multicellularity evolved independently in different multicellular lineages, the composition of ECM varies between multicellular structures; however, cell adhesion, cell-to-cell communication and differentiation are common functions of the ECM. The animal extracellular matrix includes the interstitial matrix and the basement membrane. Interstitial matrix is present between various animal cells (i.e., in the intercellular spaces). Gels of polysaccharides and fibrous proteins fill the interstitial space and act as a compression buffer against the stress placed on the ECM. Basement membranes are sheet-like depositions of ECM on which various epithelial cells rest. Each type of connective tissue ...

Elliptic Curve Method
The Lenstra elliptic-curve factorization or the elliptic-curve factorization method (ECM) is a fast, sub-exponential running time, algorithm for integer factorization, which employs elliptic curves. For general-purpose computer, general-purpose factoring, ECM is the third-fastest known factoring method. The second-fastest is the quadratic sieve, multiple polynomial quadratic sieve, and the fastest is the general number field sieve. The Lenstra elliptic-curve factorization is named after Hendrik Lenstra. Practically speaking, ECM is considered a special-purpose factoring algorithm, as it is most suitable for finding small factors. , it is still the best algorithm for divisors not exceeding 50 to 60 decimal, digits, as its running time is dominated by the size of the smallest factor ''p'' rather than by the size of the number ''n'' to be factored. Frequently, ECM is used to remove small factors from a very large integer with many factors; if the remaining integer is still composit ...

Every Child Ministries
Every Child Ministries is a Christian charity and mission agency that works for African children. The charity is specially known for its advocacy on behalf of neglected, downtrodden, and marginalized groups of African children. It was first incorporated in the US in the state of Indiana in 1985, but is now incorporated and recognized as an NGO in all three of the African countries it ministers in.

Electronic Countermeasure
An electronic countermeasure (ECM) is an electrical or electronic device designed to trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy. The system may make many separate targets appear to the enemy, or make the real target appear to disappear or move about randomly. It is used effectively to protect aircraft from guided missiles. Most air forces use ECM to protect their aircraft from attack. It has also been deployed by military ships and recently on some advanced tanks to fool laser/IR guided missiles. It is frequently coupled with stealth advances so that the ECM systems have an easier job. Offensive ECM often takes the form of jamming. Self-protecting (defensive) ECM includes using blip enhancement and jamming of missile terminal homers. History The first example of electronic countermeasures being applied in a combat situation took place durin ...

Electrochemical Machining
Electrochemical machining (ECM) is a method of removing metal by an electrochemical process. It is normally used for mass production and for working extremely hard materials, or materials that are difficult to machine using conventional methods.Todd, H. Robert; Allen, K. Dell; Alting, Leo (1994), Manufacturing Processes Reference Guide (1st ed.), Industrial Press Inc., pp. 198–199, . Its use is limited to electrically conductive materials. ECM can cut small or odd-shaped angles, intricate contours or cavities in hard and exotic metals, such as titanium aluminides, Inconel, Waspaloy, and high nickel, cobalt, and rhenium alloys.Valenti, Michael, "Making the Cut." Mechanical Engineering, American Society of Mechanical Engineers, 2001. http://www.memagazine.org/backissues/membersonly/nov01/features/makcut/makcut.html accessed 2/23/2010 Both external and internal geometries can be machined. In the ECM process, a negatively-charged (cathode) cutting tool is advanced into a pos ...

Engineered Cellular Magmatics
Engineered cellular magmatics (ECMs) are synthetic stone of glass and ceramic. ECMs replicate rare, naturally occurring volcanic materials, and exhibit useful structural and chemical properties of those materials. The United States Department of Energy, US Department of Energy has recognized ECMs as an advanced material, funding further research into the manufacture and application of ECMs through ARPA-E and Savannah River National Laboratory. Properties ECMs can be engineered to include a broad range of silicate species, with various Reactivity (chemistry), reactivity. Their physical structure can range from closed to open cell, resembling pumice or porous ceramic. They can be composed of internal pore and Vesicular texture, vesicular structures with individual cross sections that can measure from millimeter down to nanometer scale. Open cell varieties exhibit extensive surface areas which amplify ion exchange capabilities (both cationic and anionic). These features make them ...
