Woa…I can’t believe I will (have to) be able answer all these (past year) questions in two weeks time. I never even seen some of the stuff asked:
(Warning: the following section may cause side effects such as fainting, stressing out, bewilderment and shock. Mental preparation and parental guidance advised)
What is the pH of 375 mL of solution containing 0.150 mol of propenoic acid (HA) and 0.250 mol of sodium propenoate (NaA)? (Ka for propenoic acid is 5.52 × 10-5.)
Draw a detailed diagram of the bell stage of tooth development and label the cells that will eventually form: enamel, dentine, cementum, PDL and pulp.
Discuss, with the aid of a diagram, the process of skeletal muscle contraction. Include the following: chemical synaptic transmission at the neuromuscular junction at the skeletal muscle, generation of action potential in the muscle, and mechanism of contraction after receiving the signal.
Write brief description notes on mechanism of breakdown of a metal in oral cavity by differential aeration cell and suggest which dental alloys might be most susceptible and why?
Name a key tissue or organ system derived from the following mesodermal component: i) paraxial mesoderm, ii) intermediate mesoderm, and iii) lateral plate mesoderm.
Contrast the anatomical form of the lower 1st permanent molar with that of the lower 2nd deciduous molar.
Microscope slide of intestine. Draw it and name the layers.
Write brief description notes on eutectic alloys and their shortcoming.
Discuss some of the challenges faced by pathogens in exploiting the potentials of the human body, the sorts of strategies used to meet these challenges, and the sort of counter-strategies which may be employed by humans keen to preserve those resources to further their own fitness.

drink, drank, drunk
Tonight i went to the engineering award presentation thingy as invited by Kelvin (yes Kelvin, not you lionel...). Anyway, saw lionel and andrew there too getting the award. It's sad though, all i got was only a few crappy photos of the whole event. That wasnt the main point, this blog is abt me...duh. After that, we went to the university club which is supposed to a very high-classed place, but now flooded by cheap ppl jus waiting for the food as refreshments. Being a typical asian, i went for all the food that i can put my hands on- and of course the drinks. And this was when the disaster happened...lol.
I got white wine, and i find it not really nice. So subconsciously i was trying to finish it real quick so that i wont be wasting it. That sort of explained what happened next. I started to feel weird. it's as if all my sensory nerves started not to function (i wont go into how achohol acts as an inhibitor or sth sth which sort of affects the action potential generated along the nerves and not enough electrical signals to stimulate the brain...simply because i dont know anything abt it...). I got to point when i cant even feel myself touching my cheeks. I thought i am just too tired or sth. Then only then it struck me that i was drunk...lol
I started to drink juice(two glasses), water(one glass), soda(one glass) thinking i can dilute the achohol. But i suppose it's too late. So, what happened? Nothing much. I didnt go around punching people or swearing, killing people or puking all over the place. I maintained my cool just sitting there. My face glowing red, my pulse increasing to over 150 per minute, my balance lost, my brain in sleeping mode. That's pretty much.
So, the lesson is:
-dont drink alchohol
-dont drink alchohol at one go
-dont drink alchohol...i cant stress that enough
-i m not a lousy drinker ok...i just drank too fast
-dont be greedy
Ok i'll end here. I need to sleep now. I'll update if i have hangover tomoro...hehe

mi mama
Yesterday I read someone’s blog. He was talking about his mom (who died 50 days ago) and reminiscing what his mother had done for him all her life. Really touching. Made me so the sad the other night and made me miss my mom also.
>>百善孝为先>>
My mom’s from KL. She lived quite a poor life. I remember she used to tell us how hard her life was. Every morning she had to wake up super early to go out to my grandma’s stall to sell food- porridge, noodle…(To tell you the truth I really don’t know much about her life when she was young, I guess I am just too ignorant or maybe I just never really cared)
>>哀哀父母为我拘劳>>
Fast forwarding to now, as in after I was born. Well, as I spent most of the time at home (call me boring or lifeless..watever), I really grew close to my mum especially when I was in Form 1 and 2 (which were in the evening session). When I am bored I would go to the kitchen (when she is in the kitchen obviously), to look at her cooking (I guess that’s why I can cook quite well now…hehe) and talk to her. Talk about what? I don’t know, just anything, can’t really remember. We used to subscribe Reader’s Digest and when she read a very funny joke she would share with me (and even though I finished reading the whole book a few weeks ago when it just arrived, I would just laugh). Sometimes, when I finished my tuition (yes, I also went to tuition) in the morning at around 10am, she would pick me up and go out for breakfast. I know that’s nothing much but I sort of started to miss it ever since I started form 3 which is in morning.
>>慈母手中线，游子身上衣。
临行密密缝，意恐迟迟归。

Last year, I came to Perth. First time without her (for a really long length of time) was quite ok though- she taught me almost everything before I came, I would also ask her if I had any big unsolvable problems. But doing everything on my own was hard work. I think you all know what I mean. I even tried cooking for a whole bunch of people (which stopped after a week I think?). I felt really tired and helpless (and annoyed by the amount of work that I had to do myself). Imagine her doing it everyday without fail for five of us in the family who never really offered a lot of help (I did sometimes when I was talking to her) and still maintaining the high-standard and healthy home-cooked meals without complain or grudge.
>>树欲静而风不止，子欲养而亲不在 >>
Reading someone’s blog really made me thinking. I really can’t afford to lose her. Especially not before I can repay what she had done all these years for me. I don’t even dare what will happen if I were to lose her (choi choi choi)…anyways, I will just end my post with how I would normally start every call I made every week…
“halo?”
“halo”
“我啊..”(me ah-again)
“你啊..”(you ah-smiling)
“嗯..”(yea)
“怎样? Ok吗?”(how’s things?ok?)
“差不多啦…”(so-so la..)
“…”
and this weekend I am going to add this:
“Happy Mother’s Day”
and God bless her..
