not bad, hubs was better than I though (only 2 pages today!).

though not looking forward to the cells reading tonight (its like 28 pages x.x)

I don't think I'll bother. As has been said heaps of times, once you're a few weeks in you just don't have the time for the readings. Also, the extra info in the readings is hardly ever in the exam (1 in 60 questions or something).

Really? I got like nearly 5 pages of notes.... There's one word that I missed when he gave an example of something, I can't remember..... I'm so tired- scared that I'll get sick as everyone around me is sick..... And also, where are you staying this year, jonathan810?

Freshers' Flu - Wikipedia, the free encyclopedia !

Haha I have the fresher flu... so annoying being really sick on a day with 4 lectures, I could barely stay awake in physics!

I'm living at home with my parents (food and laundry service !)

So isosmotic means the solution has the same osmotic pressure right? How can we tell this? Also did people do the glucose problem from the lecture..? what did you all get?

edit:what does the same osmotic pressure actually mean?

I think people are getting confused about this because they keep relating isosmotic to osmotic pressure and it's actually easier to get your head around if you relate it to permeant/impermeant solutes. Isosmotic means the total concentrations of solutes on one side of the membrane is equal to the total concentrations of solutes on the other side WHETHER THEY ARE PERMEABLE OR NOT. In respect to the urea example, although water and urea have the same concentrations of solute (around 300mosmol/L), water is permeable and urea is SEMI-permeable. This would cause the water to flow into the cell to dilute the small number of impermeant solute from urea... (it is hypotonic: cell swells). From my understanding, this would then mean the osmotic pressure would NOT be the same because the volume will be increasing (the cell is swelling).

Hopefully I got this right, if anyone wants to correct me please do! Ross Anderson gives a good response on the blackboard discussion board that is reasonably clear to follow if this still doesnt make sense

I think so, isosmotic means that the pressures are the same. eg 275-300 mmol/L in the ECF, ICF etc

And nope, forgot about the 5% glucose problem.. oops. I'll try do it today before HUBs, no doubt he'll quickly run over it anyways.

 

[Voldemort]

So you know that osmosis is the passing of water across a semipermeable membrane, right? Osmotic pressure is the pressure that must be applied to one side to stop osmosis.
That's what I remember from HUBS

Hi guys. Hope everyone's doing well today. (yy)

I was just wondering what the max amount of lectures I could miss. I'm going overseas for a bit (dad getting remarried) and will be back by Tuesday- just in time for a lab on the next day. I'm already missing 4 classes today.:unsure: Also do you guys have an idea how long it takes for the staff to put up podcasts?

Thank you

 

[Cathay]

I was just wondering what the max amount of lectures I could miss.

In terms of hard-and-fast rules of the course? To quote the CHEM convenor: "We don't care if you come to lectures, at all." Not going to lectures is your own loss, labs aren't nearly the same story though - if you don't show up and can't explain yourself you'll be denied terms (i.e. not be allowed to sit the final exam) and will fail the paper.

Also do you guys have an idea how long it takes for the staff to put up podcasts?

The process itself doesn't take long, whether said staff are there and can be bothered is another question. CELS and HUBS tend to go up either later that day or the day after, PHSI does it every weekend I think, and CHEM takes 1-2 weeks.

For terms requirements, as per Cath. For your sanity when you return, I'd say any more than 2 or 3 days worth of lectures and you're going to have to go ballistic for a few weeks to catch up.

IMO you might get away with it now more than ever, CELS only really just finished the introduction today and physics is pretty much just going over the basics still, with chem being much the same. HUBs could be a bitch to catch up on, so much information every lecture.

lulwut pretty much says it all xD

though if you are leaving, since the chem slides pretty much say everything, its not much of a problem (as with physics as long as you have the textbook and the slides)

Cells- depends on your background of biology- perhaps getting an e-copy of the textbook and following the reading/reading the lecture slides (there are tangents, but its better than nothing)

Hubs- well, we're all screwed trying to catch up so you'll have to work harder later on to catch up.

I got the GLM thingy for CELS, is it worthwhile going through and studying up on the answers or just waiting until the lectures/labs teach us the info? Apart from that I think I'm pretty much on top of everything at the moment..

There are stuff you definitely won't know until after certain lectures (it might say "complete this after you've revised lectures x to y"? I don't remember), but for the most part, you are expected to find GLM answers for yourself wherever they go beyond lectures and labs.

Fair enough, I'll wait until next weekend.

The HUBs GLM thing is a joke, the part where you identify what type of learner you are is funny.. I got a 3/3/3 split.. What a waste of time lol.

Lol, yeah. I made the mistake of doing the first HUBS GLM booklet.. A mistake one doesn't make twice.

Hahaha, I'm doing it now - I guess it's nice for revision (the parts actually related to the course), try and fill it all in without reference to notes made.
