My field of interest would definitely lie in pharmacy.
Since I'm one of the few who cannot stand the look (or even the presence) of fresh blood and will get all dizzy at even the sound of it, I cannot become a doctor. Therefore, pharmaceutical science was my plan B.
As I aspire to help people and hopefully save lives (even though people said "DIAN, PEOPLE WILL DIE UNDER YOUR CARE BECAUSE YOU'RE SUCH A LAZY BUM"), I want to handle and hopefully create new drugs which can cure and reduce my patient's pain.
I checked my MI Link way past the NUS/NTU/NIE open houses and was a tad bit disappointed because I actually planned to go there and interview one of the aspiring doctors. Then, I tried to call my Chem/Phy tutor who tutored me last year for O Levels because he was undergoing a medicine course. However, he could not be reached (I think he changed number), so I decided to just research on the course! :)
RESPONSIBILITY:
* responsible for the registration of medicines & the continual review of approved medicinal products
* facilitate the timely introduction & availability of new and innovative quality medicines in Singapore and the region, including medicines targeted for diseases prevalent in the region
MAIN ACITIVITES RELATING TO THE CONTROL OF MEDICINAL PRODUCTS INCLUDE:
* evaluation and approval of applications for new product licences, amendment and renewal of existing product licences
* continual review of registered medicinal products
* evaluation and approval for import of unregistered medicinal products on a named patient basis.
* approval for the import of medicinal products for the purpose of re-export
* evaluation and approval of applications for licences for the purpose of importation of registered medicinal products on a per consignment basis
People always say: "Put ahead all your weaknesses first, then feed yourself with your strengths."
(NOT SURE IF THAT WAS REALLY WHAT PEOPLE ALWAYS SAY OR NOT, BUT IT DOESN'T MATTER BECAUSE IT SOUNDS NICE!)
Weaknesses in Chemistry
1) I think I'm in deep shit because I still don't understand the combustion data. CxHy(g) + (x+y/4)O2(g) -> xCO2(g) + y/2H2O(l)
EVEN AFTER READING FOR A ZILLION TIMES, I STILL DON'T GET IT, THAT'S WHY I GOT STUCK IN A LOT OF QUESTIONS IN THE PREVIOUS ASSIGNMENTS. IT'S HOLDING ME UP AND CAUSING ME TO HAND IN MY ASSIGNMENTS LATE. SOS I NEED HELPPPPP!!!!
2) I get demoralised very quickly (even in any other subjects) when I don't get the topic that we're learning. And I'm quite weak in self-learning so the next chapter might be quite a hassle for me. Nevertheless, I'll try!
3) I procrastinate a lot. Last Friday, I actually had the intention to blog right after I reach home from hockey. But in the end, I decided to do something else. And now, I'm blogging a week's work in a day. I need treatment.
Strengths in Chemistry
1) I have always thought that my calculation was very good. Used to get full marks during sec sch and all but then as mentioned, I got stuck on the combustion data formula thingy and that holds me back!
2) I am ok when it comes to balancing equations but I think I take quite some time to balance it. I prefer not to rush. Rush = more mistakes!
3) My love and interest for science helps me stand strong and persevere. Although I prefer Physics more, I know that chemistry is also needed and is part of our daily lives. Therefore, I want to do good in both sectors :)
1) Common Apparatus used in lab:
- deionised/distilled water
- white tile
- beaker
- pipette filler
- retort stand
- funnel
- pipettes
- conical flask
- burette
- dropper
- glass rod
- volumetric flask
- weighing bottle
- electronic analytical balance
2) To prepare standard solutions:
eg Using a fixed mass of solid sample
-requires weighing
OR
Using a fixed volume of liquid sample
- requires use of pipette
2) Choosing an appropriate weighing vessel.
a) Ensure the weighing pan is clean.
Use a brush to remove solid particles or a paper towel to wipe off liquids.
b) Tare the balance.
c) Centre the vessel on the balance.
d) Add the required mass of substance into the vessel.
e) Record the mass after the reading has stabilized.
f) Before leaving, ensure the balance pan is clean from spills.
g) Transfer sample to a container, and re-weigh the vessel.
h) Mass of sample transferred is the difference in of the two readings.
i) Recording readings to appropriate number of decimal places.
Tips & Precautions
Use a draft shield for accurate mass readings.
Use a clean and dry weighing vessel.
Use a weighing bottle for weighing hygroscopic substances.
Allow a hot sample to cool before weighing.
When weighing volatile substances, ensure you seal the vessel before taking the final mass reading.
Ensure the substance weighed is dry.
3) Choosing an indicator
a) BROMOTHYMOL BLUE; strong acid-strong base
b) PHENOLPHTHALEIN; weak acid-strong base
c) METHYL ORANGE; strong acid-weak base
4) When reading the liquid level...
Eye should be at level of meniscus, not above or below.
Reading from an angle results in parallax error.
(1) Learnt that H3PO4 is actually Phosphoric acid.
(2) Was told to memorize the definition of important terms in chemistry.
eg, Relative isotopic mass is defined as the mass of one atom of an isotope* compared with 1/12 the mass of one atom of carbon-12.
* recapping chemistry o levels, isotopes are atoms with the same number of protons but different number of neutrons.
eg2, Relative atomic mass (Ar) is defined as the mass of one atom of an element compared with 1/12 the mass of one atom of carbon-12.
Things to learn:
How to type the small numbers of the formula via the keyboard. Forgot the steps Ms Jee taught us the other day. Anyone?
