Laser And Treatment

A laser is an electronic-optical device that produces coherent radiation. The term "laser" is an acronym for Light Amplification by Stimulated Emission of Radiation. A typical laser emits light in a narrow, low-divergence beam and with a well-defined wavelength . This is in contrast to a light source such as the incandescent light bulb, which emits into a large solid angle and over a wide spectrum of wavelength.

A laser consists of a gain medium inside an optical cavity, with a means to supply energy to the gain medium. The gain medium is a material (gas, liquid, solid or free electrons) with appropriate optical properties. In its simplest form, a cavity consists of two mirrors arranged such that light bounces back and forth, each time passing through the gain medium. Typically, one of the two mirrors, the output coupler, is partially transparent. The output laser beam is emitted through this mirror.

In aesthetic laser treatment platforms , it's applications are :

1. Hair removal 2. Skin treatments 3. Skin tightening laser 4. Telangiectasia & leg veins 5. Vascular Laser 6. Pigmented lesions 7. Wrinkle treatment

They are, in fact, aesthetic treatment platforms with the most advanced and safest technology for gentle and efficient treatment of various undesired conditions of skin, veins and vessels as well as wrinkle treatment and skin tightening.

Automatically run programs when starting Windows

If there are applications or commands that you run every single time you start your computer (Email comes to mind) you may want to consider setting things up so that these programs run automatically during the Windows XP startup. This can be done quite easily in XP by creating shortcuts and shuffling them around.

Here's how: Windows XP has a startup folder located at 'C:\ Documents and Settings\ (your user name)\ Start Menu\ Programs\Startup.' Shortcuts placed into this folder will be run automatically when Windows XP starts up.

If you already have shortcuts for the programs you desire to use, copy and paste them into the startup folder. Otherwise, go to 'start\programs,' select the program you would like to create a shortcut for, right click it and select 'send to' then 'desktop.' This will create a shortcut on the desktop that you can then use

Meaning of different website extensions : .htm , .html , .shtml , .asp , .pl , .cgi , .jsp. , php

Do you know why some Web pages end in htm, others end in html, others end in asp and so on? Why all the different extensions?

You can see some of the most common extensions on these URLs:

• .htm.
• .html

When the Web started, it ran almost exclusively on UNIX machines and all pages were Html which was the standard file extension. When people started using PCs running DOS or Windows as Web servers, however, the four letters in "html" were problematic. PCs followed an 8.3 naming convention that allowed only three letters in the extension. So the world made room for two standard extensions: html and htm

Htm and Html pages are static. The file is lifted off the server's disk and sent verbatim to the client.

• .shtml :
  

Pages tagged with shtml reveal that "Server Side Includes" are being used on the server.. With SSI, a page can contain tags indicating that another file should be inserted in place of the tag in the existing page. So a page is lifted off the server's disk and the server makes all the substitutions indicated. Then it sends the final page to the client. This approach makes it very easy to change things like headers and footers on pages across an entire site.

• .asp :
  

Active Server Pages (asp) is a Microsoft technology that allows even more flexibility. A Web page can contain Visual Basic code that the server executes when it lifts a page off the disk. This code can do just about anything -- read databases, run other programs, custom format pages based on the user's ID, etc. You have a great deal of flexibility. On the other hand, your Web pages now contain code that may have bugs in it, so it is possible for a page to "crash." With freedom comes responsibility...

• .pl :
  

The pl extension stands for PERL, a scripting language. The page contains nothing but PERL script, and the script builds the page on the fly. The script can also do anything as in asp pages.

• .cgi:
  

The Common Gateway Interface (CGI) is a standard protocol for interfacing external application software with an information server.Each time a request is received, the server analyzes what the request asks for, and returns the appropriate output.

• .jsp
  

Jsp is one of the latest additions to the Java Enterprise suite of APIs. "Jsp" stands for "Java Server Pages" and is effectively Java's response to ASP. The code embedded in a page is Java rather than Visual Basic.

• .php
  

"Php" used to stand for "Personal Home Page," but now it's really just "PHP," which is a scripting language that's mostly used with Linux.

Create a password reset disk for WinXP

Here's an important tip… If you are using a password protected user account in Windows XP (and you really, really should be ) you might be nervous about forgetting your password. Well here's a way to put your mind at ease, at least a little bit. Windows XP allows users to create a password reset disk specific to their user account. This disk can be used at the welcome screen to reset your password in the event that you do forget it.

To create the disk: Go to start\control panel\user accounts. Select the account you are currently logged in as.Under the 'related tasks' heading in the top left corner, click 'prevent a forgotten password' to open the forgotten password wizard. Insert a blank floppy disk and follow the instructions to create your password reset disk.

To use the password reset disk in case of emergency:
Once you have created a password reset disk for a specific user, the next time the password for that user is entered incorrectly at the welcome screen, a message will pop up asking if you have forgotten your password. At this point you can elect to use your password reset disk. Follow the instructions to reset your password. Note: There are a couple of possible problems with the above procedure. For one, if you have used Windows XP's built in encryption feature to encrypt some of your files and folders, but have not yet updated to service pack 1, do not reset your password, as you will lose access to all the encrypted data. Once you have got service pack 1, it is safe to use the disk. Also, you cannot gain access to the reset feature if you have disabled the welcome screen on XP .

Keep your reset disk in a safe location, because anyone else can also use it to reset your password....

BIOS Passwords Hacks / Reset BIOS Password

Forgot your BIOS Password ... Don't worry try the following hack ...

To perform this hack you will need:

* A #1 or #2 Phillips-head screwdriver, or (less likely) a T-15 TORX driver or a 1/4" hex nutdriver, to open the case
* Needle-nosed pliers if you are working with jumpers
* A small flashlight or headlamp

With tools at hand, perform the following steps:

1. Turn the PC off (this means a total shutdown, not merely standby or hibernate mode) and disconnect the AC power cord.
2. Remove the cover from your system (this step may require tools, undoing a thumbscrew, or flipping a latch or two).
3. Refer to the user manual for the motherboard to find out how to "reset CMOS" memory. You may also find a label for specific jumper or switch settings marked on the system board.
4. Change the switch setting or jumper position to a specific position or remove the jumper entirely as prescribed in the manual to clear or reset the CMOS memory.
5. Wait 20-30 seconds for the memory to clear out from lack of power.
6. After 20-30 seconds put the switch or jumper the way it was before for normal use.
7. Reconnect the power cord and start up the system to see if the settings have changed to defaults.
8. Shut the PC down, disconnect the power cord, replace the cover, reconnect the power, and power up the PC.
9. Enter the BIOS setup program to configure the system as needed. This may include setting the date and time, selecting disk drive parameters, and selecting which devices the system uses to boot up with first.

If your system does not have a "reset CMOS" jumper or switch , the only option is to locate and remove the coin-style battery cell (or on some very old PCs, the battery pack), as shown in , that provides the power to the CMOS memory
