what is full form of KDM?

Question

CaptAnil · Accepted Answer

KDM: Gold Jewelry from some places is / was marked with a KDM stamp which means that the Jewelry was soldered with Cadmium. Cadmium called 'Kadium' in some places and marked KDM was traditionally used in soldering of gold jewelry for its good properties of liquidity and melting at lower temperatures, which is not the case any more as Cadmium is known to create toxic fumes when melted, which are very dangerous to health, over a period of time and may be harmful to humans, making the gold jewelry, some countries have banned the use of Cadmium from use, from workshops. Jewelers in many parts of the world now use gold solders, which are free from Cadmium. Please note that the wearer of the gold jewelry is not harmed, this issue only concerns the manufacturing process. Also note that using any type of gold solder either KDM (Cadmium) or other gold solder, to make the jewelry does not guarantee the purity of gold, as the purity is a representation of the percentage of gold in any metal.

In the traditional method, silver and copper were used to solder gold. But many jewellers have switched over to cadmium since it gives good melting fluidity during the soldering process.

Even customers prefer KDM gold, as loss or wastage of gold during the soldering process is minimum because cadmium gets readily dissolved

in gold.

Jewellery workers using cadmium have experienced problems like cough, irritation in throat, gastroenteritis, vomiting, wheezing and anorexia.

Toxic fumes released when gold is soldered with cadmium can damage the health of the workers

In computing, KDM (KDE Display Manager) is a graphical login interface for computers using Unix-like operating systems. It is the K Desktop Environment

KDM is the replacement for XDM, the default X display manager. KDM allows users to pick their session type on a per-login basis. Like KDE, it uses the Qt toolkit and can be configured from the KDE control center. It also allows theming and user photos. The most recent releases allows the user to install complete themes to play like the login manager, GDM.

A simple KDM login dialog box has a list of users on the left, stating their username, their "real name" and optionally also containing a small picture that can be chosen by the user or the administrator. To the right from the list is a greeting and a picture. These items can be customised using the KDE Control Center. Users may also replace this picture with an analog clock. Under the picture/clock are the Username and Password text boxes. On some systems, users will find a session selector under the password field where you can select the kind of session type you want to start, e.g. KDE, GNOME or a simple terminal. At the bottom, there is a series of buttons which offers commands to shut down and reboot the computer, restart the X server or start a tool to manage users.

KDM has an optional autologin feature; this is unsecure, but users used to other operating systems request this sometimes
