In environmental chemistry, chemical oxygen demand (COD) tests the measurement of oxygen that is consumed during the test by particular organic compound. In other words the COD test is used to measure the amount organic matter present in the particular organic compound. Its application is commonly in the measurement of organic pollutants present in the surface water or river water and to clean the water. A common method for chemical oxygen demand analysis is to react the strong oxidizing chemical such as potassium dichromate or dichromate ion with the organic matter.

Technology is big business in Education. Laptops, data shows, interactive whiteboards and hand held data devices are becoming increasingly common in schools across the globe. The progress is inevitable, but not equitable and in many cases the technology is lying idle as teachers with limited technological expertise and/or interest struggle to use the technology to its maximum potential.
It is an interesting fact that teaching is an isolating profession and yet one in which you are constantly surrounded by people. Continue reading Effective Multidisciplinary Cohesion
There are three types of magnetic surveys: ground based, aero magnetic survey, and ship borne survey. When the target of interest requires closely spaced readings, the ground magnetic survey is preferred. The ground based surveys can be carried out on foot or on a vehicle.
The traverse direction and the station spacing should be chosen first. The traverse direction is across the strike direction of the target. Continue reading The Magnetic Surveys
The memories on Bijelo Polje (town in Montenegro) of the thirties of this century left but a fade traces. Just some memories on singing and joy. The life was something that made people hide their desire for joy. The songs could be rarely heard, but on the wedding celebrations. That is why it was especially nice when in summer evenings one could hear the songs of reapers coming from Obrovo and the surrounding mounts. Continue reading Balkan Life Story
It is easy to get confused and think that the scientific method is only something science teachers make you do in school or what the pros use in labs looking for cures to diseases. But the steps to the scientific method need to be followed no matter what kind of experiment is being done. Continue reading Steps To The Scientific Method For Quick And Easy Science Fair Projects
Okay so, it turns out that when astronauts are in space for long periods of time (over 2-weeks) their brains go through noticeable structural changes. That’s pretty interesting and proof of the incredible plasticity and ability of the human brain. Now then, we now know what sorts of changes occur from research and it is interesting that the images of dolphin brains have also been imaged.
What do we know about the similarities of a human brain in space in a low-gravity environment as it learns to operate in a three dimensional realm of movement and the brain of a dolphin which has structurally evolved to operate in a similar low-gravity environment with movement in 3-Dimensions (cite: 1).
Why do I dare to compare or ask this question?
Well, there was an interesting article on the New Atlas website posted on January 31, 2017 titled; “Astronauts’ brains change shape as they learn to move in space,” by Michael Irving, which noted:
“The study found space travel changes volume of gray matter in different parts of the brain, perhaps the result of shifting fluids due to a lack of gravity, and the brain working overtime to relearn the basics of movement in a strange new environment. Continue reading Dolphin Brains, Human Brains, And Long-Term Space Travel – A Theory Of Mine
Each school and for that matter each science teacher likes to run a science fair differently. Sometimes they change how they do things from year to year, They want cool science experiments and they want the kids to learn something. Sometimes they try to make it less competitive and more informative. Continue reading Cool Science Experiments For Science Fair- Think Ahead!
Consumers have lots of choices when it comes to substituting reusable products for disposables. Theres less waste, and reprocessing often saves money. Continue reading Reusable Rockets Could Make Space Travel Cheaper and Greener: How Close are We?
Thinking about is not really just about all in which how to improve app ranking farfetched generally. The actual Zune inside the ‘microsoft’ response to the actual Ipod touch. It truly is tricky to determine that’s the actual one who did that during this level of competition nevertheless you can view in which having your Zune is usually wonderful entertaining. You’ve got the possibility to help weight countless melodies in the nuvi along with hear just about all that you might want with out being interrupted as well as advertising.
Getting this kind of with step explain to you exactly where you should begin looking for that totally free Zune downloads. Continue reading What Exactly Does One Indicate By Means Of Free Increase Your App Search Traffic With Aso Of Charge Newspaper?
Temperature is an important factor in the manufacturing of medicines. Materials which are highly responsive towards temperature changes can corrode easily, hence maintaining the temperature in a manufacturing area is of vital importance.
The temperature is kept in check by temperature mapping, which means recording the temperature of the storage area. The different parts of a manufacturing area will have different temperatures, some will be colder than other parts or some a bit warmer. Temperature mapping ensures all the different areas achieve the required temperature. Continue reading Temperature Mapping in Pharmaceutical Areas
