The reason behind the Green Green in Islam green colour is simply its association with the Islam ic paradise. The idea of handing out green envelopes is based on the Islamic concept of zakat , where every Muslim is required to provide at least 2.5 mainly to the needy. However, providing green envelopes to others in Malay homes during Aidilfitri today is not only given to the poor guests, but also to the middle class and to the upper class .

The cell envelope is the cell membrane and cell wall plus an outer membrane, if one is present. ref DorlandsDict three 000035855 envelope ref Most bacterial cell envelopes fall into two major categories Gram positive and Gram negative . These are differentiated by their Gram staining characteristics. Function As in other organisms, the bacterial cell wall provides structural integrity to the cell. In prokaryotes , the primary function of the cell wall is to protect the cell from internal turgor pressure caused by the much higher concentrations of proteins and other molecules inside the cell compared to its external environment. The bacterial cell wall differs from that of all other organisms by the presence of peptidoglycan poly N acetylglucosamine and N acetylmuramic acid , which is located immediately outside of the cytoplasmic membrane . Peptidoglycan is responsible for the rigidity of the bacterial cell wall and for the determination of cell shape. It is relatively porous and is not considered to be a permeability barrier for small substrates. While all bacterial cell walls with a few exceptions e.g. intracellular parasites such as Mycoplasma contain peptidoglycan, not all cell walls have the same overall structures. This is notably expressed through the classification into Gram positive and Gram negative bacteria. Types of bacterial cell envelopes Mycobacteria The Mycobacteria have a cell envelope which is not typical of Gram positives or Gram negatives. The mycobacterial cell envelope does not consist of the outer membrane characteristic of Gram negatives, but has a significant peptidoglycan arabinogalactan mycolic acid wall structure which provides an external permeability barrier.

Unreferenced date December 2009 A self addressed stamped envelope SASE , stamped self addressed envelope SSAE , or just self addressed envelope SAE in the United Kingdom UK , is an envelope with the sender s name and address on it, with affixed paid postage stamp postage and mailed to a company or private individual. Often, SASEs are used when requesting information about products or services or sending manuscripts to literary agents. Companies and charities use SASEs in order to save on postage each recipient can afford the cost of a single stamp and envelope, but the business does not want to pay for the postage on all the letters it sends out. One of the most common uses is when companies are legally required to send something upon request, such as a winners list at the end of a sweepstakes the company will require a SASE with the request to avoid paying postage. SASEs are also vital in the hobby of autograph collecting and amateur radio . An enthusiast will send a request to a celebrity or sportsperson athlete through the mail. Included with the autograph request as a SASE, in which the celebrity or athlete is to return the autographed item. For amateur radio, operators will send a SASE when requesting the other station s QSL card. International reply coupons SASEs cannot easily be used for foreign mail, since senders rarely have supplies of mint foreign stamps. Rather, international reply coupon s are used, and these can be purchased over the counter at Post Offices. In many cases, and as a courtesy, users of IRCs also send a Self Addressed Envelope to save the receiver the cost and time of buying and filling out an envelope.

In physics , the slowly varying envelope approximation SVEA is the assumption that the envelope mathematics envelope of a forward travelling wave pulse varies slowly in time and space compared to a period physics period or wavelength . This requires the spectrum of the signal to be narrow band ed&mdash hence it also referred to as the narrow band approximation . The slowly varying envelope approximation is often used because the resulting equations are in many cases easier to solve than the original equations, reducing the order of all or some of the highest order partial derivative s. But the validity of the assumptions which are made need to be justified. Example For example, consider the electromagnetic wave equation math nabla 2 E mu 0 , varepsilon 0 , frac partial 2E partial t 2 0. math If k sub 0 sub and sub 0 sub are the wave number and angular frequency of the characteristic carrier wave for the signal E r , t , the following representation is useful math E mathbf r ,t Re left E 0 mathbf r ,t , e i , mathbf k 0 , cdot , mathbf r omega 0 , t right , math where math scriptstyle Re cdot math denotes the real part of the quantity between brackets. In the slowly varying envelope approximation SVEA it is assumed that the complex number complex valued amplitude E sub 0 sub r , t only varies slowly with r and t . This inherently implies that E sub 0 sub r , t represents waves propagating forward, predominantly in the k sub 0 sub direction. As a result of the slow variation of E sub 0 sub r , t , when taking derivatives, the highest order derivatives may be neglected ref cite book first1 Paul N. last1 Butcher first2 David last2 Cotter year 1991 edition Reprint title The elements of nonlinear optics page 216 publisher Cambridge University Press isbn 0521424240 ref math Bigl nabla 2 E 0 Bigr ll Bigl k 0 , nabla E 0 Bigr math pad 3em and pad 3em math Bigl frac partial 2 ... of the slowly varying envelope approximation math mathbf k 0 cdot nabla E 0 omega 0 , mu 0 , varepsilon ... more details
External links date August 2010 Variable envelope return path VERP is a technique used by some electronic mailing list software to enable automatic detection and removal of undeliverable e mail address es. It works by using a different return path also called envelope sender for each recipient of a message. Motivation Any long lived mailing list is going to eventually contain addresses that can t be reached. Addresses that were once valid can become unusable because the person receiving the mail there has switched to a different Internet service provider provider . In another scenario, the address may still exist but be abandoned, with unread mail accumulating until there is not enough room left to accept any more. When a message is sent to a mailing list, the mailing list software re sends it to all of the addresses on the list. The presence of invalid addresses in the list results in bounce message s being sent to the owner of the list. If the mailing list is small, the owner can read the bounce messages and manually remove the invalid addresses from the list. With a larger mailing list, this is a tedious, unpleasant job, so it is desirable to automate the process. Unfortunately, most ...
