[Chemical Engineering] Separation Processes_PT
First of all, Starling's law states that the force of contraction. It depends on the length of muscle fibers of the heart. This intrinsic response of the heart is called Starling's law of the heart.
-----------------------------------------------------------------------------------------
If you look at this slide, you can see that graph, which is 'Starling's law of the heart.'
The length-tension relationship of a normal heart is shown in the lower curve.
In contrast, this increase in heart rate can dramatically increases cardiac output.
As mentioned before, an increase in a heart volume increases stroke (맥박) volume and excess volume. Therefore, we could say that the magnitude of fluid movement is dependent on the net balance of Starling forces across the endothelial barrier(내비장벽).
From this fact, We can conclude that the rate of fluid transport through the capillary walls can be modeled by Starling's law.
-----------------------------------------------------------------------------------------
Let's move on to the next slide.
----------------------------------------------------------------------------------------- Next one is about The Kedem and Katchalsky equations.
The Kedem-Katchalsky (K-K) equations, commonly and classically used to describe
the volume and solute flows of nonelectrolyte solutions(비전해질용액) across membranes.
However in biophysical practice, we usually have to deal with systems whose solutions are poorly mixed caused by effect of solute size, effect of solute charge and so on.
That's why in that system, we assume that the solutions on both sides are well mixed.
The modified K-K equation obtained here, which expresses the volume flow (Jv), includes the effect of boundary layers with varied concentrations in the case of poorly-mixed solutions.
Further more, their existences significantly reduces the stream of diluted substance (Js) and the volume stream(Jv). In order to describe mathematically these streams, it was necessary to transform the Kedem and Katchalsky classical equation into a more practical equation.
-----------------------------------------------------------------------------------------
In conclusion, Starling and Kedem-Katchalsky eqn. Both of them are describing Endothelial permeability(내피투수성). In addition, The application of the K-K practical equations is reduced to membrane systems with sufficiently diluted and well mixed solutions such as a glomerulus system.

[Heat and Mass Transfer] Speech
As you can see the screen, I'd like to talk to you "Heat transfer in refrigerator".
We, sixth team has found this journal from "International Communications in Heat and Mass Transfer", which name is "Experimental study of heat transfer characteristics for a refrigerator by using reverse heat loss method".
You might be curious about this term, Reverse heat loss method. This is the new concept, this author just came up with.
This main experiment in this journal is differently checking the heat transfer between freezer side and refrigerator side. By putting heaters into each section, they have found how and which paths the heat go forward to. This is the new concept differently checked from the original principle of refrigerator.
-----------------------------------------------------------------------------
We've divided our presentation into three parts.
First, I will explain you the reason why our team chose this journal and how important it is.
Then, we'd like to introduce you "The basic principle of fridge cooling down temperature"
Finally we will talk about the main purpose of the journal we've chosen.
So through the last part, you will know the point our team is going to discuss about at the final presentation.
Please Be ready to take a note and feel free to ask a question whenever you have.
-----------------------------------------------------------------------------
Here is a very interesting fact that a refrigerator inside a house runs for 24 / 7 and 365 days in a year until it is out of order. There is no home appliance other than a refrigerator which always runs in the world. So it is obvious that the electric power consumption by fridge
is considered as a huge cost. So for reducing electric power energy, we've chosen this journal, because it shows the experimental fact saving electric power energy in the aspect of heat transfer.
-----------------------------------------------------------------------------
Pay attention to here. This is the simplest figure which is showing the heat transfer in refrigerator. it is composed of four big parts in terms of heat transfer.
Compressor, Condenser, Expansion valve and Evaporator unit with Refrigerant.
The fluid flowing this system is Freon Gas (R12, R22 - Air condition). It is a noncorrosive fluid which means it has no a harmful function to break down the valve and pipes inside of fridge. and it is easily liquefied even at the low pressure to absorb ambient heat. So We can say that it is a qualified material as a refrigerant (fluid). I will just call it fluid to make it easy.
-----------------------------------------------------------------------------
The refrigeration process begins with the compressor. Freon Gas is compressed until it becomes very hot and high pressure.
This heated gas flows through the coils behind the fridge, which allow excess heat to be released into the surrounding air.
This is why people sometimes feel warm air circulating around the fridge.
Eventually the Freon Gas cools down to the point where it becomes a liquid at condenser.
This freon liquid is forced through an expansion valve.
Essentially, the expansion valve has such a small opening. That's why when the liquid Freon pass through this valve, it is turned into a very cold, fast-moving mist, evaporating.
This is explained by Bernoulli's theorem.
This low temperature freon liquid with low pressure is vaporized by absorbing more heat from inside of the insulation.
then its temperature rises.
this phenomenon cools down the temperature inside of fridge.
The freon gas is drawn back into the compressor, and then this circulation system begins again to continuously lower the temperature.
----------------------------------------------------------------------------
Finally, Here in the last part, We are going to give you an introduction for final presentation.
In this journal, they had tried finding these four facts based on reverse heat loss method.
First, They found How long the temperature distribution inside fridge takes to reach the steady state condition from the fridge has a electric power at the first stage.
Second, They checked the efficiency of role of circulating fans between freezer side and refrigerator side.
Third, They separated the fridge into three parts like this picture. And they utilized the concept, The overall heat transfer coefficients respectively.
So they shows the relationship between them by derivation using mathematical calculation based on zeroth and first law of thermodynamics.
Above all facts have proven the performance of circulating fan and insulation in the aspect of Heat transfer.
Basically, There are several ways to cut down the cost of electric power energy.
I will explain them at the final presentation with sub journals.
We will see you later. Thank you very much.
Does anyone have a question?

Male grooming all over the world.
Check this one first.
How do you like it?
Are they sexy enough you feel so that you couldn't get into sleeping tonight?
Hunky guys, as all you guys know that making up youself is natural and necessary to flirt ths opposite sex, Right? Like chasing for being beautiful for female, male grooming is with you all the time.
See the definition of Grooming in a dictionary.

Grooming refers to the things that people do to keep themselves clean and make their face, hair, and skin look nice.
It is incredible that words in dictionary even also refer to what you've done at this point. In other words, Nobody who doesn't care of it does catch up with the others.

Men take a great deal of arrogance in their hair styles and in the way hair can affect a man’s overall appearance.
Many men prefer to wear shorter hair because it can take years off their appearance and help them to look more masculine, sexy, strong.
Waxing is not just for women anymore. Waxing can be a great option for men to remove unwanted hair and not have to shave often. Waxing can have pros and cons, but it is a safe and easy method for facial and body hair removal.
Your face is one of the first things people will notice about you. Invest in a quality multi-blade razor with a pivoting head that will glide easily along all the planes and curves of your face and neck. In her book "Charm School For Guys," author M. Marshall says shaving on a daily basis will give your face a clean, smooth appearance that is both appealing and attractive. Groom your mustache or beard by shaving around them. This will keep the rest of your face from looking scruffy.
First impressions are important in both professional and social circles. You want to project confidence in yourself and pride in your appearance. In order to accomplish this, your grooming routine should involve more than what you've done.
To look your best, you should acquaint yourself with a proper grooming.

Use What you have to get what you want (KH Magazine)
While, world leaders have had to rely on what they have to get what they want.
In other words, You need to know how to use what you have to get what you want, if you want to be called leader.
Let us be clear, right now. Take your time and think about “What you have” and “What you want” for a second. Is one of them flame (girl, boy friend) making you happy? Is it High point GPA (Grade Point Average) filling you up enough? Sufficient knowledge or Money you can show off front of people enough?
What I’ve come to realize and I’d like to talk about is that the key is to fully understand what you have and, equally important, know what you want. You have to take a profound look at your dreams, goals, and aspirations, followed by a good, hard look at your assets, resources and talents. And then, you have to figure out a gap between the two.
It happens at the same times each year.
I get too busy (work, school, life) and I desperately need to have a look back on “what I have”, “what I want” with Starbucks coffee. I don’t think people look to leaders necessarily because they are smarter or because they know something that others don’t.”
“People see what the leaders have to get what they want.”
I’ll give you example. This is story about when I was working at company, TUNAP Canada Ltd. with Managing Director. He always told me “Necessity of being leader is to know perfectly what you have`. One day, we bought one application called ERP (Enterprise resource planning) as a project. Even though it was very strong application, it needed to be modified a lot. It is vivid that Software company has powerful tools but business mind. Especially attached documents didn’t make sense in the business field. We’ve accused of it, and eventually we’ve got free edition. In other words, they didn’t know what they have to get what they want. Despite they have massive information, they don’t know what they have to get what they want (they don’t know how it they have works).
It is obviously impossible that you have everything. I don’t compel you to be a leader, but to know what you have to get what you want.
You might be asking you over and over again, if you agreed with my perspective. I’ll give you a way I think.
Here’s the thing though. To get what you want to do, you have to first base it off a reference point.
This reference point is based on your past experiences. If you have not accumulated a set amount of experiences, you can’t possibly generate a meaningful answer in that regard.
Get to know what you have is. Go out the world and explore the difference from where you are now.
Hope you go all out in all your goal pursuits and in pursuing your interests.
Put your heart and soul in everything you do.
I hope it leads you to totally different world you’ve been faced with. Take care.

Beauty is in the eye of the beholder

The meaning of that is attractive qualities or features.
Thus It's because we are always faced with coosing who or what is more attaractive and has beauty.
It other wors, we usually itemize (make a priority) beauty that we will meet.
But the choice comes from personal tendency.
From my experiences, Whenever i hung out with my girlfriend, my friends would have wondered why I was with her. I was seen not to be going on her. They thought we weren't a good match. But she seduved me with her beauty and charm. All in all (on the whole), As time went by, they coulnd't deny she was very attractive. In my opinion, it depends on an individual. Rarely can you see a 30 year dirrerance between couple.
There is another point of view (perspective.) Generally beauty is not bad not cruel, not trouble maker nor nice. There is no doubt that "Miss Universe" is gorgeous and awesome. They have their own individual attractiveness. As we can recode that face, personality, figure, intelligence, confidence, pureness(Innocence). Sexy and helpful mind for the poor and so on.
I've never expected that the beautiful people are doing something bad.
In conclusion, the people personally (Individually) have their own specific beauty on their mind. But it is not out of meanings (territory). You just run it by your honest mind. They can answer what they want to get.

All the day of my life

A conflict among people can happen frequently.
Because each person has their own way of thinking and pursue their perspective.
However how worse a conflict gets depends on how concerned a person is about his / her opponent.
It can be both a controversial thing and efficient compromise.
Since I came here, I think I've chosen the ways way to live. There haven't been any conflicts.
May be if there ever is one, I will wisely solve the problem. The wisest solution to a conflict is that people don't invade an individuals (spatial) boundary. Don't hurt and don't live beyond your means.
Let us think about two types of conflict. A conflict is a paradox. Being conflicted means that people have an idea against others. They are going to find a way to improve something they have.
Meanwhile, they will compromise to develop it from each other at the same time.
It makes something worse or better.
It is a paradox. It is likely that every time we are faced with a conflict. It is regarding our way of thinking. When we have homework, at times, we hesitate to do that because we have options which are taking a rest and watching TV and so on. So a conflict like this might happen too naturally to figure out that it is conflict. All the time, we have conflicts withing ourselves. For thinking through something, we need an experienced, clever.
They can lead us to get out of conflict.
Despite the fact that you find it hard to get a wise mediator, we should reach or get to be.
In conclusion, the life you are making, has many aspects.
It is following the way you look or where you stand and see in a distance .
See the picture from a distance, then you can see a bother picture than before.

I Just Want To Be Myself.
I am typing and writing ‘I just want to be myself’ and then nailed it my blog.
I've found myself being quite an odd character in an environment consisting of people who thought
more about how to get a raise than actually doing what they wanted.
That's how i would define myself and people surronding me.
I put my pen to a paper and wrote again ‘I just want to be myself’ and then bear in mind
,which cannot be removed. and i hope it keeps.

People dropped by my desk and asked, "what?!" and I answered - I just want to be myself,
do the things I love and pursue my passions in life.
I don't want to dress in a suit and tie just because that's how your supposed to dress.
I want to wear a casual suit I like it. It is the same way I'll do front of people and i want to be candid.
"Be myself and Change myself are the hardest things i've ever felt.
That's why i have chosen the way how i look good instead of being myself."
Was that way real myself? Or Have i been just afraid of being myself which is not that good...?

Restoration and Relaxation.
- the restoration of Andrew's sight
- his favorite form of relaxation was reading detective novels
It happens at the same times each year.
I get too busy (work, school, life) and I desperately need to retreat to a comfy chair with a book, a good music and a hot cup of tea.
Tea is my restorative. It takes me away from everything else and lets me decompressed and
relaxed.
Book always gives me the eyes and mentality that let me think different way.
- These days, I am reading and i have appreciated it you present those books.
"501 Things You really Should know", "Wear Your Life well", "Nudge"
And with a good music, I am going to be in the air of heaven on my bed.
2010 Year.
I have been learned How i can be relaxed and What is real i should chase for.
All of sudden, I am going to be faced with things(school and work) make me busy.
But in this time, in a different point, I could start it.
Why don't you put things aside and restore yourself..?
Best Regards.
Andrew.
