Determination of Total Cyanide Without Distillation

Determination of total cyanide by normal EPA methodology requires either manual or on-line distillation from a sample acidified with a strong acid. Serious problems have been recognized with these traditional methods. This article presents interferences associated with EPA approved methods and describes a non-distillation method based on segmented flow on-line UV digestion-gas diffusion with amperometric detection. This technique eliminates the need for time-consuming distillations, has a throughput of up to 30 samples per hour, and is virtually interference free.

Simple Things To Do During Heat Wave

There are lots of things or actions we could do during heat wave. If it happens, better be safe.One of the important thing is to keep calm. Being calm will keep you active and take decisions wisely. This will not create anymore problem unlike you will try to do some strenuous activity. Another thing you could do is stay indoor most of the time. This at least will not directly heat your body with some hazards and heat caused by heat wave. Keeping your body cool at the times is a good way.

Quick and Easy Homeschool Science Aeronautics Experiments

Every flying thing, whether it's an airplane, spacecraft, soccer ball, or flying kid, experiences four aerodynamic primary forces: lift, weight, thrust and drag. Let's build simple flying machines to learn about aerodynamics!

Biology - Birds, An Introduction

The most characteristic feature of birds is the possession of feathers. Because the bird-like reptiles of the Jurassic were becoming warm-blooded, the principle advantage of the feathery covering was probably the reduction of heat loss from a warm body. Modern birds have temperatures of about 40-41 degrees C which contributes to the high rate of metabolism necessary for the muscular activity involved in flight.

Sensors Used to Step Up Security

The following article discusses how sensors will keep soft targets more secure. Scientist are working to provide sensors with a similar smelling prowess of a dog. This feat will make security much more effective.

Darwin – What Changed His Mind?

The work of Charles Darwin was influenced heavily by other scientific minds of the time. Darwin's losses may have simply renewed his interest for proving God had no direct involvement in the affairs of mankind.

The Evolutionary Two - Step

Anytime evolutionary theory has been challenged by the evidence Darwinian evolutionists come up with some new incredible theory to explain the problem away – no matter how improbable the logic. Is this real science? This article explores this issue.

Secrets To Writing A Winning Science Fair Project Report

Your written report is the single most important part of any science fair experiment. A well-written report can make a pathetic project look pretty good, and a good project look exceptional. By the same token, a poorly written report is certain to sink even Nobel Prize-quality work. It's a simple equation. The winners know how to write up their science fair project reports in a way that shows off their know-how and impresses the judges.
