week 14 homework; 3 reasons not to keep dolphins in a tank

Dolphins are has complex emotional cognition like human being. That qualifies animals are not just animals. We human being put a lot of value on emotions, which is considered to be how we are distinct as human being by majority. This article gives chance to us to think about the relationship between us and animals. 

week 14 homework; evening's discussion

mum was right--Definitely right. I feel better after a cuddle with someone very familiar.

One of my friend argues "No love, no gain". Right, we actually gain from love.

burning the magic bubble--when I was a kid, I was interested in magic. But the thing is that I couldn't do as well as those professionals. They are so skilled that they actually can control our cognition.

Babies may be more language-savvy-- Interesting article. It could be related to genetic information which clearly describes people are by nature different, not differ by education or family environment alone.

week 12 homework; check the following link

http://micro.magnet.fsu.edu/cells/index.html

We are made of about 75 trillion cells.

They are so tiny but each of them are so distinct and they are like super little brothers.

Each of them respond to stimulation, stress, emotion, damage differently. It's just like we respond to certain events differently in real life.

week 12 homework; post thoughts on evening discussion

I felt banana equivalent dose is quite interesting idea.

It shows that our life is pretty much the life with radiation.

The only matter is that how big it is... 

week 13 homework; post thoughts on this week's discusssion

This week we talked about the relationship between us and our planet.

Quite a few of us think that we are consuming our planet too much with so fast pace.

Population is growing, so eventually we consume more.

But it is not realistic that all of our nation regulates "One Child Policy".

So our individual effort and the growth of green technology is necessary.

If each of us work a bit harder and technology is improved, we are likely to have solution to the relationship.

Week 13 homework; "the human species is living as if it had more than one planet to occupy"

I think that's partially true.

About 30 years ago, an Economist argues that 30 years later there would be no more resource for us because we are consuming so rapidly and population grows very fast.

Now, 30 years later, some people are still arguing that 30 years later there would be no more resource...

We are rapidly consuming our planet but at the same time technology is rapidly growing.

So it is hard to say there would be no more resource in the future.

How to make high fructose corn syrup (HFCS)

3 kinds of enzyme reaction

1)      Starch is made of a lot of glucose. Add Alfa amylase (liquefying amylase, type of digestive enzyme can be obtained from microorganism ) and water into starch and at 95 C. degree, Starch will be decomposed.

(Starch molecule is too big, so at step 1 we want to make it into smaller particle by liquefaction, the process to convert something to liquid)

2)      After liquefaction , cool until 55 degree C,  add glucoamylaze which will separate each individual glucose apart from starch, now we have much smaller particle, glucose.

3)      At 60 degree C, add gluco-isomerase (type of enzyme, made from bacteria) which will convert glucose to fructose, fructose is better in quality of sweetness, which is more commercially preferred

Note that starch itself is not sweet because starch is long chain of bunch of glucose.  Our tongue  can feel sweetness if it is individual glucose, but in the form of glucose chain, we can’t.

Then after some sort of processing, corn syrup will made

Corn syrup is as sweet as or slightly sweeter than can sugar, depending on how they process after the third step

The lower the temperature, the sweeter corn syrup is. Soda is sweeter when it’s stored in refrigerator

It’s cheaper than cane sugar, about 70% price of cane sugar, so nowadays in order to reduce production cost almost every soda product use corn syrup (Coke, Pepsi)

How to make biomassethanol

Theoretically we can make bioethanol from anything with high carbohydrate

(sugar cane, corn, rice, etc)

The way to create bioethanol is basically same as they way to make alcohol

Dry grind method – newly developed factory in US

Starch ingredientàdry grindàsaccharificationàbiotic fermentation(organic decomposition by microorganism to produce certain kind of material)  10% ethanol àdistill, 95% ethanol àdyhedrate, 99.5% ethanol àethanol

Bio ethanol is a fuel

Same type of alcohol Found in alcohol beverage

Motor fuel

Additive for gasoline

Occupy 10% of car gasoline (cars nowadays can run on blends up to 10 %)
