The Evils of Animal Testing Imagine your pet‚ whether it’s a dog‚ cat‚ bird‚ or rodent‚ huddled in the corner of a small cage‚ eyes wide with fear‚ waiting for the next routine experiment to be performed on it. Will the creature be cut open and exposed to a potentially poisonous substance this time‚ or sprayed in the eyes with some foul smelling perfume? Just because its not your pet‚ doesn’t mean you shouldn’t care. You wouldn’t want experiments preformed on your dog‚ why should other animals

use of sound is in the area of science called Nondestructive testing‚ or NDT. Ultrasonic testing (UT) has been practiced for many decades. Initial rapid developments in instrumentation encouraged by the technological advances from the 1950’s continue today. Through the 1980’s and continuing through the present‚ computers have provided technicians with smaller and more rugged instruments with greater capabilities. NDT ultrasonic Testing uses high frequency sound energy to conduct examinations and

only perhaps‚ to the bitter abortion debate. For decades the value of animal research has been grossly overrated. Although researchers have depended on animal test data to achieve medical advances‚ there should be other means of research because testing on animals is cruel‚ inhumane‚ and often unnecessary. Perhaps it would be more beneficial and humane to test on violent criminals such as rapists‚ murderers‚ and others on death row. The American Medical Association believes that research involving

Is the death of one worth the safety of another? Many would say no. The testing of animals is extremely unfortunate‚ but also necessary. Due to the fact that animals are perfect test subjects‚ they have helped find cures for many diseases and have made products safer for not only human use but animals as well. According to the California Biomedical Research Association‚ almost every medical breakthrough in human and animal health has been through a direct result of animal research for over a hundred

It is important that we bring this heinous practice to the attention of those who are unaware of these unethical procedures. Every year in Australia thousands of animals are killed in school‚ college‚ and university courses.

Dye penetrant inspection: Dye penetrant inspection (DPI)‚ also called liquid penetrant inspection (LPI)‚ is a widely applied and low-cost inspection method used to locate surface-breaking defects in all non-porous materials (metals‚ plastics‚ or ceramics). Penetrant may be applied to all non-ferrous materials‚ but for inspection of ferrous components magnetic-particle inspection is preferred for its subsurface detection capability. LPI is used to detect casting and forging defects‚ cracks‚ and

A Bit of Change Here and There: An Improvement to the Traditional Standardized Testing There are a lot of students out there that may regret the amount of a certain type of education that has been given to them by their teachers. A few of those students face living with human disabilities like autism and dyslexia. They feel this way‚ because they say that they are stressed out when trying to remember or take in any information that was given to them in the classroom. In fact‚ the amount of

Standardized testing is the most commonly used and well known method of testing used in the United States and many other countries around the world‚ but can harm educational quality and promote inequality. Standardized testing is used to determine student achievement‚ growth and progress. Standardized tests are tests that attempt to present unbiased material under the same‚ predetermined conditions and with consistent scoring and interpretation so that students have equal opportunities to give correct
