Open Book Exam…Really???

Image

How does one really have an ‘open book’ exam at the University level…well the name does not say it all unfortunately…there’s a catch!!! Obviously there were rules you had to obey… So I here I go…You we allowed to carry a half letter-size sheet with notes on any topic to aid in answering the questions in the exam. Seems only fair Right??? While many took this opportunity to carry notes…..others, like myself walked into the exam with nothing but a pen…Did I have any regrets? It’s 50/50, maybe if I had notes I would answered the questions in the alotted time but, looking for notes on the small sheet may have been time consuming as well…knowing my hand-writing.

The exam was manageable to say the least…it did in fact cover all the topics throught the seimester and also gave me a good idea of what to expect in the final exam.

ImageHowever I was really disappointed with the time giving to do this exam. Repeaters and New Students were placed in separate classrooms for this exam. I believe that invigilators should learn to speak to the students….like really…you’re supervising a classroom of nervous students and you’ll speak as though you’re arguing…dont gotta be so harsh. Not to mention ‘We’ only got 40 minutes to do this exam. Doesn’t she own a watch??? Oh and the constant “whispering” in front the classroom…I am sorry but I was really annoyed at the fact that our exam time was so short…many didnt get to finish the exam. At 9:46 our exam finished, well for repeaters that is…as for the new students they were still in exam mode…and obviously they got full time. I am sure many felt the same fustration as I did after the exam…but what can I do about now….nothing!!! Can’t complain….clearly….oh well its all a learning experience…I’m still gonna “mash up” final exams…We all Are!!!

Does One Really Know What Is Arsenic Poisoning??? Lets Learn More…

Image

While doing some research I came across this very interesting article entitled “Arsenic Poisoning”, discussant Michael S. Gorby, M.D, Albuquerque. This article may seem a bit miss leading at first; I actually thought this article was based on two patients who had experienced arsenic poisoning. A 17 years old woman whom attempted suicide by ingesting arsenic poisoning trioxide containing rodenticide and 64 year old man who suffered with chronic arsenic poisoning who was admitted several times in hospitals for various complications.

However, this article instead discussed the chemistry of the element Arsenic, the sources of arsenic poisoning: it’s natural, industrial and administered sources. Also the biochemistry and toxicity of arsenic, the effects of arsenic poisoning whether it is acute or chronic and the treatment of arsenic poisoning were discussed.

So What is Arsenic Poisoning???

Arsenic is a member of the nitrogen family or group 5 of the periodic table of the elements. It has an atomic number 33 with an atomic weight of 74.9 and is classified as a transition element or metalloid. Arsenic is a natural element found in soil and minerals. Arsenic compounds are used to preserve wood, as pesticides, and in some industries. Arsenic can get into air, water, and the ground from wind-blown dust. It may also get into water from runoff.

You may be exposed to arsenic by:

  • Taking in small amounts in food, water or air
  • Breathing sawdust or burning smoke from arsenic-treated wood
  • Living in an area with high levels of arsenic in rock
  • Working in a job where arsenic is made or used

Exposure to arsenic can cause many health problems. Being exposed to low levels for a long time can change the color of your skin. It can cause corns and small warts. Exposure to high levels of arsenic can cause death.
