Online Backup Service

Thursday 11 March 2010 @ 11:17 am

Online users these days can relish the advantage of a remote or managed backup service to backup and store data files on the internet. This service is known as online backup service. And those who provide this kind of service are known as online backup providers.

A special kind of software program runs the online backup systems by following a certain routine which is usually done on a daily basis. The programs functions include collection, compression, encryption and transferring of data to the online backup servers.

These days with computers becoming an integral part of our lives we need a certain method which can help us save more and more information in such a way that it never gets lost. Our reliance on the internet for most of our work has been on the rise continuously. And so, online backup services are the most convenient option for us today.

There are some conventional backup options for us like saving documents in external hard drives or portable memory sticks, but the problem with these methods is that they are not accessible everywhere. On the other hand, on the internet you can access any file or website anywhere and that too at a very fast rate.

Now, let’s talk about some important features of online backup services. Opened file backups are such services where you can backup files like outlook files or SQL database files which are left open all the time. This simplifies the jobs for IT administrators to do their backup work at any time. This service is very useful to enterprises as their backup products support this service natively.

Next up are the multi-platform backup services which can run backups on many platforms at a time. This means that backup can be performed on Windows, Macs or Linux or even UNIX systems simultaneously. Backup services for networks are known as Network backups. They can perform backups between all computer systems located on a LAN from one computer or device.

Some backup services have the feature of backing up the data from different locations pretty easily and at the same time. These services are known as multi-site backup services. The last of the features is the Continuous backup or the CDP. This service can backup data continuously or at a specified time.

These features prove that online backup services are the ultimate choice for internet users today. Not only are these online services efficient, but also very economical. There is no need for any external equipment and there is no fear of any damage or theft either. Your USB or hard drive can be broken or stolen but nothing can happen to data that is safely stored on the internet.

Moreover, your data when stored on the internet can be retrieved at almost any moment. All you need is a computer with an internet connection. Computers after all are machines and anything can go wrong with machines. So we must take necessary measures in advance to protect our vital information from being lost forever. And with online backup services are sure to make file sharing and storing 100% safe and secure.

Jason Kay recommends reading reviews and ratings of the best online backup services to choose the right one for you.

The Compound Microscope and Its Aliases

Thursday 11 March 2010 @ 11:05 am

It is compound enough to understand the technical configurations of compound microscopes. More confusion sets in when these microscopes come in several disguises when they all share the same thread. They are all compound.

So You Want a Compound Microscope

Get acquainted with the different types of compound microscopes before buying one. Yes, there are different types of this microscope, which to a newbie can be confusing; if you are procuring one you might be asked if you want a binocular, monocular, trinocular, or light microscope. Don’t cringe. Tell them outright you want microscope that is good enough to study cells and tissues and you want two-eyepieces to see them with.

You’ll be handed a binocular microscope with compound functions. But if you tell them you want a unit that has a stage with a hole in it, because that was what you saw in your school lab, you’ll be shown an array of compound light microscopes. This type of microscope uses that hole on the stage for light source, the better to view the specimen with.

As for the monocular, it’s good for microscopy experts. Do not take this if you hate the idea of squinting an eye to view the specimen. It can be confusing. Well, it can be done if you remedy this by using a patch over the other eye so you can see the specimen as one whole piece.

All about Optics

But whatever they are called, they all have convex or curved lenses. Take a long hard look at a compound microscope. There are four lenses facing towards the specimen on the stage, while the other two serve as the eyepiece. The objective lens sends an enlarged image to the eyepiece or the ocular lens so what you see is a ten times the image of the specimen. These objective lenses make it possible for you to adjust the degree of magnification of the object.

If you want a higher degree of magnification, you use the high dry objective. It is the longest of the objective lenses and magnifies objects forty times their size. There’s the oil immersion objective though not available always. This is much longer than the high dry objective. So what’s special about this? This magnifies objects one hundred times their actual size but a drop of oil must be placed on top of the sample tissue to fill the space between the specimen and the objective lens.

You will be informed that you can determine objective magnification by multiplying objective power by the ocular power. These two sources of magnification makes these scopes compound – whether these are binocular, monocular, or light. It’s all about optics with compound microscopes; nothing more and nothing less and there are no powerful gadgets hidden in these microscopes.

Knowing these facts can help you make a choice when presented with a bevy of compound scopes. However, you’ll be asked again for your brand preference. Now that’s another thing. You can dig up brand information and compare notes with friends. By that time, you can march up and announce that you want a binocular light compound microscope. That’s indeed a mouthful but then it all boils down to compound microscopes.

The Art of Invisible Life Forms Seen Through a Fluorescent Microscope

Thursday 11 March 2010 @ 10:59 am

The fluorescent microscope is a conventional light microscope and belongs to the family of compound microscopes but uses a higher intensity of light. It works two ways; it magnifies the sample and causes the sample to emit a glow or luminescence. What you see through the lens is a palette of colors or combination of colors.

Luminescence Art

The fluorescent microscope is an effective instrument for studying cells and invisible-to-the-eye organisms; this is a standard microscope for scientific research, biology, and other sciences or industries that require a study of specimens that cannot be scrutinized by the unaided human eye. For accuracy of observation, the specimen is coated with a green fluorescent protein known as the fluorophore. When light hits the specimen, it emits a long wavelength of light of a different color.

Imagine yourself in the dark and watching glow-in-the-dark objects. That’s the closest thing description to the experience of peering through the fluorescent microscope. Typically, the specimen will give off different colors as sections of it will respond different to the stimulus. It is not unusual to see different patterns and different colors. In the study of a dividing cancer cell, researchers use different color stains on the specimen. Through the eyepiece you can observe unusual shapes in green or red.

Different samples from different specimens show different structures. Some you would say resemble cubic art. The shapes range from strands of filament, globules or circles and against a canvass of dark background , the specimens give an ethereal glow. Imagine a huge luminous painting. If these were not cancer cells or cells from sick cows, it would make a good art form. Perhaps somebody out there can imitate life in art, not the other way around.

Luminescence and Scientific Research

The fluorescent microscope is instrumental in the discovery of cures for diseases. Research studies are able to study specimens of diseased and healthy cells and their behavior or reaction to different stimulus. To get a specific wavelength for the emitted luminescence, excitation filters are used. This is positioned in the excitation path before the dichroic mirroic. The emission filter is used to select wavelength of the emission and this is placed under the dichroic mirror

For everybody’s enlightenment, a dichroic mirror is a color filter that reflects colors. Used in conjunction with a light source the filter produces light perceived by the human as intense colors. The technique is popular in theatrical art. The amazing stage lights are created by filters to produce a desired effect to match the emotions played out on the stage. The same is reflected on the stage of the fluorescent microscope.

This special mirror is also transparent to heat, therefore allowing visible light to be aimed where needed and this transparency allows infrared heat waves to exit through the mirror’s backside. This explains why the illumination produced more intense colors but less heat. To sum it up, fluorescence improves research methodologies for cellular biology, immunology, medical research, microbiology and other related fields.

Researchers can observe the different behaviors or characteristic of cells, thanks to the invented different stains and this microscope. Scientific research will continue to discover cures for different diseases. As you read this, much work is still done to improve the fluorescent microscope. Expect better and more exciting microscopy illumination as this microscope becomes more powerful.
