High Temperature Insulation Wool
Mineral wool is any fibrous material formed by spinning or drawing molten mineral or rock materials such as slag and ceramics. Applications of mineral wool include thermal insulation (as both structural insulation and pipe insulation), filtration, soundproofing, and hydroponic growth medium. Naming Mineral wool is also known as ''mineral fiber'', ''mineral cotton'', ''mineral fibre'', ''man-made mineral fibre'' (MMMF), and ''man-made vitreous fiber'' (MMVF). Specific mineral wool products are ''stone wool'' and ''slag wool''. Europe also includes glass wool which, together with ceramic fiber, are entirely artificial fibers that can be made into different shapes and are spiky to touch. History Slag wool was first made in 1840 in Wales by Edward Parry, "but no effort appears to have been made to confine the wool after production; consequently it floated about the works with the slightest breeze, and became so injurious to the men that the process had to be abandoned ...

Revolving Credit Facility
Revolving credit is a type of credit that does not have a fixed number of payments, in contrast to installment credit. Credit cards are an example of revolving credit used by consumers. Corporate revolving credit facilities are typically used to provide liquidity for a company's day-to-day operations. They were first introduced by the Strawbridge and Clothier Department Store. It is an arrangement which allows for the loan amount to be withdrawn, repaid, and redrawn again in any manner and any number of times, until the arrangement expires. Credit card loans and overdrafts are revolving loans, also called evergreen loan. Typical characteristics * The borrower may use or withdraw funds up to a pre-approved credit limit. * The amount of available credit decreases and increases as funds are borrowed and then repaid. * The credit may be used repeatedly. * The borrower makes payments based only on the amount he or she has actually used or withdrawn, plus interest. * The borrower may ...

RCF Audio
RCF S.p.A. (formerly Radio Cine Forniture - R.C.F. S.r.l.) is a widely recognized Italian manufacturer of high performance audio products including power amplifiers, loudspeakers, digital mixers and digital signal processors (DSP). History RCF is an Italian audio products manufacturer founded in 1949 in Reggio Emilia. The first products sold were microphones and electroacoustic transducers (loudspeakers). In the late ’60s, concert sound was going electric, and many loudspeaker pioneers were searching for high-powered devices to use in their designs. RCF was one of the first European OEM suppliers for international brands, thanks to the experience built on high power transducers. After a few years, thanks to the in-depth know-how in loudspeaker technology, RCF began to develop and produce sound reinforcement systems under the same brand. The introduction of the ART Series, in 1996, has established RCF among the few global manufacturers of active loudspeakers. The TT+ High De ...

Row Canonical Form
In linear algebra, a matrix is in echelon form if it has the shape resulting from a Gaussian elimination. A matrix being in row echelon form means that Gaussian elimination has operated on the rows, and column echelon form means that Gaussian elimination has operated on the columns. In other words, a matrix is in column echelon form if its transpose is in row echelon form. Therefore, only row echelon forms are considered in the remainder of this article. The similar properties of column echelon form are easily deduced by transposing all the matrices. Specifically, a matrix is in row echelon form if * All rows consisting of only zeroes are at the bottom. * The leading entry (that is the left-most nonzero entry) of every nonzero row is to the right the leading entry of every row above. Some texts add the condition that the leading coefficient must be 1 while others regard this as ''reduced'' row echelon form. These two conditions imply that all entries in a column below a lead ...

Real Closed Field
In mathematics, a real closed field is a field ''F'' that has the same first-order properties as the field of real numbers. Some examples are the field of real numbers, the field of real algebraic numbers, and the field of hyperreal numbers. Definitions A real closed field is a field ''F'' in which any of the following equivalent conditions is true: #''F'' is elementarily equivalent to the real numbers. In other words, it has the same first-order properties as the reals: any sentence in the first-order language of fields is true in ''F'' if and only if it is true in the reals. #There is a total order on ''F'' making it an ordered field such that, in this ordering, every positive element of ''F'' has a square root in ''F'' and any polynomial of odd degree with coefficients in ''F'' has at least one root in ''F''. #''F'' is a formally real field such that every polynomial of odd degree with coefficients in ''F'' has at least one root in ''F'', and for every element ''a'' of ''F'' ...
