Change the background or wallpaper,

Click on the tab labeled Desktop and choose a new background or wallpaper from the list that appears at the bottom left corner. It is also possible to have another image that does not appear on the list as background. Click on Browse... and look for the image you want as long as the format is compatible. For example .bmp, .jpg, .gif.Once the image and type of view have been selected Click OK.

The screensaver

Sometimes the computer remains inactive a few minutes. It is recommended to have a screensaver to avoid having a still image on the screen too long because this can damage the monitor.

From the list, choose the screensaver you like best; a small preview is shown above.

You can modify the time it takes for the screensaver to appear by adjusting the time on Wait.

Configuring the mouse

The mouse is a tool that is used constantly and it is recommendable to have it set up to our needs as well as possible. In the following page we show you how to set it up to your own needs.

The Buttons

On the Buttons tab you can adjust the set up of the mouse to suit your needs.If you are left handed. WindowsXP allows you to change the configuration of the buttons so that the right button realizes these functions.

We can also adjust the Double-click speed for a slower or a faster double-click.

The pointer

On the Pointers tab we can choose the type of pointer the mouse is to have when it moves, when it is busy, when it is used, etc.

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
ninjadapaul
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?

Kim Reply
or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
