The Benefits Of A Microscope Video Camera

A microscope video camera is a very important tool. Since the advent of the art of recording things visually, our world has changed for the better. We can not imagine a world without a video camera now. It helps us in making permanent visual records of the physical world that is so tiny that neither the human eye nor a normal camera's eye can pick it up. If we ignore this microscopic world, we will not gain an understanding of many things that affect us. There is so much in this microscopic world that influences our physical world. For example an illness is generally caused by a microscopic element such as a virus, or bacteria.

Microscopes have been around for almost four hundred years. We have developed this technology to such an extent that now we can magnify things down to their electrons. A microscope video camera helps in recording the images of amazing changes that take place among cells. It makes the visual data available to the scientists, to study and analyze this data in depth. Now you would not need to preserve delicate glass slides of all the specimens in order to continue your study of the specimen. It has revolutionized the working ways of scientists.

A microscope video camera is very different from a traditional microscope. It comes with a lens that has been designed to fit into the microscope's eyepiece. This lens is connected to a device that records the images of the object that is under study. This device stores these images in its memory. These images are then sent to a computer through a USB cable. Now the images can be stored on the computer for further study and analysis.

These stored images are amazingly clear with high resolution. On your computer, you have the added advantage of enlarging and editing these images according to your need. It is astonishing how you can capture images of processes right when they are happening. Even an active process like cell division can be recorded. You have the choice of converting these processes into still shots for in depth analysis.

You can do just what ever you want with these images, for example you may make notes on these images and send them as email files. You may decide to seek the opinion of a colleague sitting half way across the world from you. Life becomes so much more exciting with it.

Besides these, there are some other advantages of using microscope video cameras...

These cameras have made the medical and scientific research much more convenient. They have made many kinds of delicate and precise surgeries possible. Their use has streamlined a lot of research and manufacturing jobs. The scientific community owes a big thanks to the genius who invented the microscope video camera.

Humid Hides For Leopard Geckos

Humid or moist hides are vital for leopard geckos health. Without access to proper moisture and humidity most leopard geckos have trouble shedding. Some will even experience toe loss and problems digesting food. But what exactly is a humid or moist hide. The best way to provide a humid hide is a plastic container with a hole for access. The container should have 2-4 inches of perlite, vermiculite, or moss on the bottom. This substrate should be moist but not sopping wet. A good way to test this is to squeeze a ball of this substance in your hand. It should drip slightly but not pour water. Heat is essential, so place this container over the hot side of their enclosure.

We have found that a hole placed on the top of the container is much better that one placed on the side. Leopard geckos are good climbers and good diggers. A hole on the side often leads to all the vermiculite being kicked out of the container. One note of caution. Baby leopard geckos should never be given a humid or moist hide with perlite or vermiculite. Instead their moist hide should be a damp paper towel in small plastic container. It is very easy for baby geckos to eat the perlite or vermiculite and become impacted. We lost one of our very first babies to impaction this way and it was only after months of care that our other babies were able to pass all the perlite that they had eaten.

Salty Water In - Fresh Water Out

In many poor, third world countries, even having the resources to obtain electricity presents a problem. Due to the lack of logistics, as well as the finances even if all of the logistics were in place, alternate methods are necessary in order to have the basics that those in more financially fortunate areas of the world have.

A recent development at Delft University of Technology (TU Delft) in the Netherlands is a basic windmill that operates a pump, in turn utilizing reverse osmosis to output fresh water from the salty seawater that is put in. Reverse osmosis is a process used to purify concentrated solutions (often water with high levels of dissolved salts) in which pressure is applied to the more concentrated (or contaminated) solution on one side of a semipermeable membrane. The result is the movement of solvent, but not solutes, from the more concentrated side to the more dilute side, thus separating clean solvent from the concentrated solution.

So, basically, in laymens terms, reverse osmosis purifies the salt filled sea water so that it is able to be used for drinking water. This development by Delft University is a critical advancement for small villages located in arid areas near the coast.

Using windmills for desalination is nothing new. These contraptions have previously been utilized and have been marketed already. The windmills on the market currently use wind to produce electricity, and then store that electricity in order to begin the process of reverse osmosis. Due to the expensive nature of this, as well as the fact that energy depletes during the procedure, TU Delft contrived a method that is a bit different. Their technique is more energy and economically efficient.

Their method, unlike the others, runs directly on wind power. The middle step of storing the electricity has been completely eradicated from the equation. By storing water (which is more cost-effective than the electricity storage), calm periods, when there is no wind, are not as dire of an issue.

The windmills that are in use for this process are slow-moving and strong. The estimations that have been done up to this point on the windmills in question gauge them to be able to provide drinking water for a small village of around five hundred people. This is not per week, or per month. These estimates are on a per day basis through the reverse osmosis process of one windmill. University of Delft is aware that an emergency supply needs to be in place to consume during the inevitable calm periods when the windmill is not able to use the wind power to operate the reverse osmosis procedure.

The first test run for this new development is set for the beginning of March, in which the windmill that has been operating near Delft will be dismantled and relocated to Curacao. The prospects of this succeeding will be monumental for villagers who lack fresh irrigation and who have to employ manual techniques to obtain any semblance of drinkable water. The economical aspect, along with the quicker, machine-operated abilities villagers will now have to acquire such a basic need, will surely have colossal effects on poorer, third world countries.
