Assalamualaikum guys,

We meet again in another Reflective Journal session, and this is the 4th session. Okay guys, for this week, we had a special lecture conducted by Dr Hazran, who just arrive from Japan for 3 months. He joined a research about Medical and Biotech in Japan.

Okay, 1st of all, I came to the class and due to it almost 9am, the class is almost full, I have to sit at the back. My point is, I can't see what is on projector actually. I expected a good explanation from Dr Azran Azhim then.

I was sitting at the back -___-

Well he started his speech by introducing himself, telling us what is Bioelectronic, the course that I wanted to enrol before then. Well, he said that bioelectronics is a field that is worth to be joined since there are many things haven't been discovered yet.He told us that he worked in Japan for 5 years ( I was whoa-ing because it is the only country I wanted to go soo much )

right after briefing about himself and his researching field, he started to show us what is inside his slide. He mentioned many things and some of it are quite familiar to me. I learnt it before and could understand what he tried to explain (while the others were complaining they don't understand the lecture

Firstly, he told us basic components and some simple stuff about electronics, it was like the first time I started to learn electronic, my teacher describing all components, then he went through some formulaes as a basic calculation.

then, we proceed on series and parallel circuit, these are the very fundamental part in electronics

( I wonder if there is anyone here couldn't catch up with these things ... )

yeap, really fundamental right ? even highschooler can understand this things, then, Dr Azran mentioned about voltage divider

this is an example of circuit which we can apply voltage divider

 these are applicable formula for the solution of this circuit

after describing briefly about the voltage divider, he wen through even deeper which is about filter in RC circuit. RC circuit involve these :-

- low-pass filter

- high pass filter

The function off low pass filter is working like a filter, I put in from my understanding, it simply allow the low frequency signal to go through and  reduce the higher frequency. Simple enough right ?

this is the circuit which apply filtering effect

low pass filter circuit

high pass filter circuit

well, I learnt these stuff during matriculation, so, it won't be a big problem for me to understand. okay, after this, things has turn out to be more complicated but I got the rhythm, and Im too into this thing, quite interesting and it itself is awesome, we're exposed to Doppler Effect

rafi rook my picture when I was asking Dr few questions

this is the question I asked him

well, what is Doppler Effect huh ? well, in a simple word, it just a change in frequency of wave when observer and source is moving

lets say that you are moving towards the sound, you will hear that the frequency of sound is raising and if you move away from the source, the frequency is reducing.

what is the relation between this sound stuff and bioelectronic ? haha, its quite complicated to explain it though, but let me tell you something, do you how do they take your blood pressure ? I'll show you a short video about using doppler device to take a blood pressure, but it was used for a pet :p

so, how was it ? simple and informative right ?

and I will show you how a simple animation about doppler effect theory

 This is how the waves are working

Simple and understandable (for me, haha)

the theory is simply said that the waves will follow the movement of the source, if you are walking ahead while saying "aaaaaaaaaaaaa", your voice will follow it too, it will produce a shorter wavelength due to previous voice at the back and your current voice which is spoken at in front.

okay, then, we are going even confusing, we were learning about some Biology stuff, I was exposed too much into DNA stuff, though it is interesting, but it is complicated ... well, the DNA is stand for

DeoxyriboNucleic Acid

don't ask me what is it, I afraid I will tell the wrong fact about it. but yeap, that's it, he was talking bout this for the remaining time left, it is about ... half an hour I guess. He also showed us a funny but informative video, have a view :)

well, I love the fact that our dna is almost the same as chipanzees ... shesss -___-

oh my goddddddd - chipanzee

but yes, Dr Azran told us about even we human being, there is only 0.1% different dna ... errr ... yea, I mean the stuff inside the dna :3  and he also told us if we extract the super tiny dna inside ourselves, the length could reach Moon from Earth, fantastic right ?

okay guys, I guess that's all from ...

wait, Dr Azran ended his lecture and we still got a little time to be spent with our blogger marker, haha, Dr Kamal (waving my hand) :3

Okay, Dr Kamal came and the first thing he said was ...

 "I don't want to take your time too long"

hahaha, I guess he knew what we were thinking. We have to revise math due to math test afterwards, but yea, he made his speech simple and cool, he told us about the journal, I mean, our mark for the 1st half. He paste it on the board at level 3. Alhamdulillah, I got 77 out of 80 (aminn)

then, he told us something bout the other 20 marks, how can we get another 20 marks ? well, we have to make a presentation, the previous student they have to work on powerpoint, which I prefer the most when doing a presentation, but then, he told us that we won't be using powerpoint for this year, I was like ...

"WHATTTT ?"

wait, why don't we use powerpoint ?

"We want you to present your research by using poster"

.

.

.

.

"WHATTTT ?"

hahaha, awesome, okay, I never thought it will be a poster, well, this is another place for me to expose my creativity in artworking, well, poster isn't bad, and I agree with him, well, lets do it by postering :3

Dr Kamal has divided the group member according to each of our personal advisor(PA). Well, as for my group, we are in the special case, I wonder how Wani can joined us even she is under different PA, but we 3 knew each other well, so, it won't be a problem, wait who I mean by we 3 ? I didn't tell you yet ? oh my god, forgive me, this is it

ZUREEN AZRA BINTI AZHARI

HAFIZUL ASYRAF BIN AHMAD

SYAZWANI BINTI ABDUL MANAF

well, Im looking forward for their great cooperation, they are sporting afterall ;)

Next, Dr Kamal show us about the benchmark and how can we grab all marks during the presentation

it base on these :-

Quality

Content

Organization

Attractiveness

Main Idea

well, we have the list what we have to do and be aware for what we mustn't put. Stay tight to the rule and make a great presentation, Good Luck feezul (hahah, wishing to myself ? how upset it is) >.<

after that, Dr Kamal ended his speech and we were scattered away.

Time to study math :3

okay, that's all for this entry, thanks for reading, ja na ;)
