Electron microscope offers many advantages over the traditional microscopes. There are three different types of electron microscopes. They are the transmission electron microscope, the scanning electron microscope, and the scanning-tunneling electron microscope.
The transmission electron microscope transmits electrons through a small slice of a specimen in order for the image to be seen. These types of microscopes are great for seeing inside the cells.
Other types of the electron microscope are the scanning tunneling microscope and the scanning electron microscope. Both these microscopes allow for an in depth look at materials. The scanning microscope can actually allow scientists to view items in 3-D because of the excited atoms.
The tunneling microscope actually creates a tunneling current between the electrons on a specimen and the microscopes tip to make the image. These are very high tech microscopes.

Posted in email Fraud, email Phishing, email Scams, email Spam at 3:38 am by admin
These days we do get many spam mails and mails related to Phishing, Scams and many other things. “Phishing” is a high-tech scam that uses spam to deceive you into disclosing your personal information like credit card numbers, bank account information, Social Security number, passwords, or any other kind of confidential personal information. Identity theft is the goal of this process. I do get these kinds of mails saying they are from PayPal, Citibank and many others.
Sometimes these fraudulent mails take you to the websites which are similar to the original sites. We do get mails related to Work-At-Home Scams. These mails are really tempting asking you to pay $5-$100 and telling you that you can earn $500 per day!!!. Some examples of this type of scams offer opportunities involving handicrafts, stuffing envelopes or medical billing on your home PC.
Other mails involve Credit repair, Mortgage Loans etc. These kinds of emails have become very popular with the current issues that many people these days are suffering from bad credit.

Posted in Erasing HardDisk Data at 11:40 pm by admin
Even if you delete files on your hard disk you can get back the data very easily. Using Data Recovery tools you can get back your data very easily. Though you may not guarantee 100% success most of your data can be retrieved back.
So if you have any confidential matter on your Disk just deleting the files will not help you. You need to wipe off your disk to completely erase all your data. Wiping tools generally fill the entire disk with 0’s so that your data is removed completely. Deleting all these files though the delete key will most likely just erase their shortcuts.
The reality is that the deleted files are still stored in the hard drive and that they only became invisible because their shortcuts had been deleted. The OS just removes the pointers to those locations. So you feel that the data is lost. But the data is still present on your disk. The only disadvantage of opting to wipe disk is the time it requires to do so.
