What is Laboratory Information Management System?

2008-12-08T03:14:00.001Z

A Laboratory Information Management System (LIMS) is computer software that is used in the laboratory for the management of samples, laboratory users, instruments, standards and other laboratory functions such as invoicing, plate management, and work flow automation. A LIMS and a Laboratory Information System (LIS) perform similar functions. The primary difference is that LIMS are generally targeted toward environmental, research or commercial analysis, such as pharmaceutical or petrochemical, and LIS are targeted toward the clinical market (hospitals and other clinical labs).

Today's trend is to move the whole process of information gathering, decision making, calculation, review and release out into the workplace and away from the office. The goal is to create a seamless organization where:

Instruments used are integrated in the lab network; receive instructions and worklists from the LIMS and return finished results including raw data back to a central repository where the LIMS can update relevant information to external systems such as a Manufacturing Execution System or Enterprise Resource Planning application.
Lab personnel will perform calculations, documentation and review results using online information from connected instruments, reference databases and other resources using electronic lab notebooks (ELN's) connected to the LIMS.
Management can supervise the lab process, react to bottlenecks in workflow and ensure regulatory demands are met.
External participants (department, company) can place work requests and follow up on progress, review results and print out analysis certificates and other documentation (perhaps even historically).

In fact, with the advent of SOA and other Web 2.0 technologies, today's (as of 2007) LIMS is being defined as a complete ERP for the laboratory, no longer restricted to sample monitoring and results entry. Although it can be client-server or PC-based, it is increasingly web browser-based and provides a large assortment of functionality.

LIMS are frequently used in industry, whereas academic labs have been slower to adapt LIMS due to the large overhead involved in installing and maintaining such systems. Several minimal LIMS or ELN systems for small research groups are starting to appear, and with the advance of high throughput technologies and Systems_Biology it is likely that more academic labs and small research groups will adopt LIMS or ELNs.

How to Restore Deleted Files

2008-12-06T07:24:00.004Z

Accidentally deleting your precious pictures, photos, and files is bound to happen to anyone of us sooner or later. I hope that you do not encounter this dilemma, however if you do, you may possibly have a chance to recover the files that you have deleted. One way is to get a professional IT guy that specializes in file or data recovery, which in itself can be very expensive. The other way is to buy a program that recovers and restores your deleted files and photos.

Well this is your lucky day because you have actually hit the jackpot by finding this fantastic free program called Recuva. I know I was ecstatic when I found it and actually recovered my photos that I had accidentally deleted from the recycle bin. I seriously thought that it would not work, because after all, it is a free program after all.

"Recuva (pronounced "recover") is a freeware Windows utility to restore files that have been accidentally deleted from your computer. This includes files emptied from the Recycle bin as well as images and other files that have been deleted by user error from digital camera memory cards or MP3 players. It will even bring back files that have been deleted by bugs, crashes and viruses!" Quoted from the Recuva website, it just sounded too good to be true.

When can you use Recuva to recover and restore your deleted pictures, photos, and files?

· When you have recently accidentally deleted a file, photo, or picture from your computer

· When you haven't used your computer too much and overwritten the deleted file

· When this program says “No overwritten clusters detected” and that the file is in Excellent state after scanning your drive

When can't you use Recuva to recover and restore your deleted pictures, photos, and files?

· When you have formatted your computer hard drive

· Sometimes if you have defragged your computer

· If the program says the file has overwritten clusters

What are the results from my tests with recvua?

· I have two hard drives and scanned both. One is C drive and one is D drive. C drive is the main hard drive and D is storage. Nearly all the files that showed up were available for recovery.

· D drive had very old files show up. Half the stuff I could hardly remember because I had been storing files on there for a few years.

· C drive had less as I had recently formatted it, but all the recent deleted filed were available.

· Then I decided to defrag C: and then scan it again. This definitely reduced the number of files that were in Excellent condition to recover. It probably overwrote 75% of files by defragging.

· I was amazed at what it actually recovered. It had every little thing that had been stored in my internet history, cookies, and other stuff that you thought would have been gone. It was almost scary how much detail this program went in to. All this from a free program.

What does Windows do with deleted pictures, photos, and files.

Even when you have deleted a file from the recycle bin it is not really gone. Windows simply marks the file as deleted, and waits for the space to be overwritten for it really to be deleted. If you didn't format or defrag the drive the file may possibly be there for years to come. This is what happened with my D drive.

Notes:

· Files that has Excellent state and with the comment No overwritten clusters detected can be recovered.

· You should always recover your file to another drive as you might overwrite the file your are trying to recover.

· You can also recover deleted photos from your camera storage card! How great is that?

This program is totally free and is made be the same guys that made Ccleaner. Their programs don't nag you to upgrade and they have no spyware contained in them. So, enjoy it...

Virus Transfer Methods

2008-12-02T12:50:00.004Z

There are different methods through viruses may be transferred from one computer to another.

1. Now- a-days, most of the viruses spread due to receiving unknown e-mail messages that contains viruses. When a user opens such an infected message, the virus is also loaded into the computer memory. In this way, many other program files loaded into the memory are infected. This virus is also transferred to other computers when e-mail messages are sent from the infected computer to them. Due to these viruses, some time an auto generated email message from your email ID sends to your friends from your side with different virus messages. Never open unknown and attractive subject line email messages, always scan first even if you know the sender of the message.

2. Another way of spreading virus is by using Internet and other networks. For example, when you download infected executables files or data files from the Internet or from a shared disk on the network, viruses are transferred to your computer. It must be noted that many software are available on the Internet with free of cost. Most of that software contains viruses, for example free PHP or ASP scripts are the main source of virus, always get these scripts from reliable sources. In an LAN, if a computer contains a virus, then all the computers on the network may be infected with that virus.

3. One important means of exchanging data is through the use of removable media like, CDs, MP3 player, ipod and flash devices. So, when you copy the data from one computer to another by using a removable media, the viruses are also transferred.

4. The virus can also infect your computer by using pirated software. The software, which is installed into your computer without license is referred to as pirated software. Some companies may intentionally attach some virus programs into their software. This program will only activate when it does not find some special files like license files on your computer.

How to access the restricted or banned websites

2008-12-01T06:39:00.004Z

You can access the restricted or banned websites with the help of this tip. You may have problems to accessing your favorite's politics, news, and sexy websites in your office and other public places. Sometimes these websites banned by Government, ISP and maybe by your office network administrator. This tip is very useful, if you are using internet particularly in school, college and office.

Follow the given points to access the banned website:
Technique 1: Search the banned website, for example www.friendster.com in Google and yahoo search engine then open the cached copy of that page to access the website. You can get also cache link of that website, if you search in Google with keyword cache:URL name and get cache link to access the website.

Technique 2: Another method to access the banned website using its IP address, because you can open the website with IP address instead of actual URL name. This technique bypasses the URL based restrictions. For example if www.myspace.com is banned in your school, you can open it using IP address 216.178.32.51. You can search online IP conversion tools to get IP address of any website.

Technique 3: There are some mini web browsers can help you to open the banned websites, for example Opera Mini Browser, install it and try to open any banned website. Another Real Player browser can successfully help you to access the banned website. This Real Player browser bypasses the many restrictions of website banned tools.

Technique 4: There are many websites Anonymizer tools available to fetch the banned website. These anonymous surfing tools that protect your identity on the internet and give the access to banned sites. As far as the service provider is concerned you are viewing a page from Anonymizer and not the blocked site.

These tips are very useful to access the banned websites in your university, cybercafe, office and other public places.

How to Backup the Files

2008-11-30T18:42:00.002Z

As most of you know, I recommend backing up your computer on a regular basis. Since I'm always harping about it, I thought it might be a good idea to actually explain how to do this!

First, what exactly does it mean to "backup" your files?

To backup simply means to copy files to another disk. This can be in the form of using a program designed to do backups or just doing a straight copy from your computer to a floppy (probably a lot more than one floppy), a zip disk , or CD-RW .

For a zip disk, just copy and paste the files you want to save onto the disk. For a CD-R or CD-RW, use your CD burning software. (Note that most CD burning software and Zip drives come with some kind of backup utility you can use if you like).

If all your files will fit on a single CD or Zip disk, then you're in good shape just copying your files straight to it. If your files are too large, you're probably better off using a backup utility, since they can "split" your files up automatically and most can even compress them.

That's really all there is to it. You just take the files you want to be sure to save and copy them to a disk or CD.

Now, here's my advice for easier backups:

One question that seems to come up all the time is. "If I do a re-format and re-install every year or two, how can I be sure I get all my important files?"

I use to have a terrible time with this one. I would hunt through every folder on my hard drive searching for my data. I would still miss stuff and lose it.

Well, a long time ago, I decided to keep any file I create (documents) or want to save (i.e. downloaded software) in the My Documents folder. Then when I go to backup my info, I know it's all in one place. I back up My Documents and it's a done deal. I have it all.

I also advocate putting sub-folders into the My Documents folder. You can do this from most "Save As" dialog boxes by clicking the "New folder" icon. You can also do it from Explorer by opening the My Documents folder, right-clicking on a blank area, then selecting New, Folder from the resulting menu.

Make sure you backup your e-mail and Favorites too! You can set current versions of Outlook Express (and many other e-mail clients) to save your e-mail to a specified folder, like the My Documents folder. Doing that will insure you at least keep your e-mail.

As for the Favorites, those you'll have to work a little harder at. They are usually found under your C:\Windows folder. XP users will find them under the Documents and Settings area.

Now, here's a tip-in-a-tip:

I didn't know you could do this - kind of found out by accident- but you can actually drag your Favorites folder to your My Documents folder. I tested this on Win 98/ME/XP (I'm sure it will work on Win 2000, not sure on 95). Each time, it worked perfectly. Explorer didn't "lose" any of the favorites and since they are in the My Documents folder now, it makes for MUCH easier backups.

What about program files?

My advice on backing up programs is not to - as long as you can re-install them. I personally back up just the stuff I have "made". You know, things like documents, web pages, pictures, graphics, etc. If I had to take time to make it and save it, I'll back it up.

If it's a program I can reinstall, then I don't back it up. After all, if I lose it, I can always reinstall Besides, many programs have files in locations other than their own directory - so it makes it hard to find everything.

Oh, and if you're backing up because you're doing a reformat of your hard drive and a reinstall of Windows here's something else to consider -

If the reason for the reinstall is poor system performance, you don't necessarily want to copy old files to the newly formatted hard drive. Sure, most of them would probably be OK, but what if you're transferring a file that was causing some of your bad performance? It's kind of like getting a new car and putting used parts on it.

Of course, there's not any kind of "fixed" rule for backing up or not backing up your program files, so use your best judgment

One final idea for our more advanced users:

If you find yourself doing the re-format thing fairly often, you may want to partition off a section of your hard drive for your data. If you keep all your information on a separate drive, you can re-format your Windows drive all you want and your data stays safe on the other drive partition.

A word of warning though. If you decide to do this, only keep data (documents, spreadsheets, pictures, etc) or downloads on the drive. If you install programs to it, you may find that when you re-format you need to re-install those programs anyway because they had DLL files that were living in the Windows System folder.
