Everyone has a terrible day. Or the only easy day was yeasterday.

I waked up with headache and bad mood in this morning by suffering the pain of muscle obtained from the hard work at weekend that moving nearly 4 tons of bulky brisk for my friend. I realized that I am aging and lack of excersie. The bad feeling was accompanying with me for the whole day and brought the bad luck for me. I broke a valuable part on a specific device. Although everyone said "No worries" to me today, I still feel extremely frustrated for p erfomance today. Beside the terrible experience for today, another evil is waiting for me ahead that it is the group meeting. I have to squize something to report in the meeting to prove that they will not pay for nothing back. Frankly speaking, I got nothing good for reporting. There will be another round of blaming waiting for me. I think I should take a week off to fresh my mine and rethink what I am doing. Just a thought.

Brewing Beer part 2

The gravity of original solution finally reaches around 1.010.Then it is the time for bottling.(The burger is not the part of business).After bottling, two cubes of carbonation were added into bottle for 740 ml.
However, it still needs at least up to 7 days before it is drinkable. During these days, the second step of fermentation will on going during fortnights.

Beer brewing part 1

Coopers is the first Australian beer I ever drank when I arrived here. It definitely change my view on beer that is all beers made in a big barrel before bottling. Coopers is type of beer which is partly made in bottle, not entirely in fermentation facilities, which means it can be made at home by own hands. And raw materials for brewing beer are fairly available in Australian major supermarkets and some brewer shops.

So, as a big fun for beer, it is hard to refuse a chance to make beer by myself not just for economic issue and also due to it is a way for me to understand Australian culture.

The receipt of how to brew beer at home could be found at internet where there are also some videos out there. The major parts of brewing process are 1 mixing, 2 first step fermentation, 3 botteling and 4 further fermentation.

1. Mixing
I bought 1kg coopers brewing enhancer 2 and a can of concentrated malt solution for beer brewing before I mixed them all together with 2L boiling water in a pot. And I kept boiling it for around 20 mins. Then I poured them into big drum with 25L volume, thermometer and air lock (shown at the second figure)

2. First step fermentation

As far as we know, beer is the mixture solution containing alcohol generated from the fermentation reaction in which micro organism, mostly yeast, uses the grain as carbonation resource for the anaerobic reaction thereby maintaining its life cycling. Therefore, fermentation is the core of whole story for the beer brewing. Yeast , as the main role for the movie, needs water, 'food' and temperature, three key factors for keeping it alive while alcohol coming out from its living. According to the current status, Yeast came along with coopers can. Water and grain (the food) are more than enough. The temperature is last and most important factor for the beer brewing. If it may not be in prefer range, the yeast may die and whole process will be fail. On the other hand, the yeast needs a wide range of degree from 18 to 32. It could be easily met when I did it at Adelaide summer days. During the fermentation procedure, the thermometer attached on the wall of barrel presented that temperature was in the range, which means everything is under control.

During the fermentation process,  the change of gravity of mixture is the indicator for the beer brewing. And hydrometer is measurement for testing the gravity. Approximately 40 ml of solution sampled for everyday is put into 50 ml cylinder before hydrometer dipped in and gave reading of gravity. The initial reading at day of mixing was 1.034 before it kept decreasing until it would reach and maintain at around 1.006, the final gravity. It will need bottling and second step fermentation.

To be continued.

The only easy day is yesterday

The last stuff I gonna do is to post one blog here.

I have to face an issue that I lack of efficiency for my research work. It mainly focuses on the mechanism of generation of acid mine drainage and the feasible method for fixing the problem.

 "Acid mine drainage is the seepage from the sulfide mineral oxidation when water is presented. It is extremely toxic and environmental hazard.", I repeatedly keep talking about the definition of Acid Mine Drainage (AMD, not the Advanced Micro Devices) to remind folks this stuff was a natural product from the eco-chemical reaction while it is serious disaster coming along with mining activities that brings huge stock of money to people by sacrificing future of us and our children and grand children. Every time, when I mention this, it is a typical way for researcher to scare the public for the aim that getting more attention from common people to pushing government and mining companies to take some moves for this problem. AMD is a critical environmental issue that gives us no time to sit and wait until it may be solved by itself. However, for any reasonable people, no one actively wants to clean up the mess he made during a profitable business. The reason for that is effectively managing this problem is complex and giant project. It is also a kind of business that pouring money in with nothing comes out.Consequently, figure out the way to let potential sponsors, like mining company and government, to join together to invest in the a profitable business is another job for me beside understanding the mechanism and methodology of prevention.

First blog for here

I am not sure what happened today.But I definitely set up my first blog for the foreign blog website which is blocked by the GFW. I try to use this website as a notebook for recording my life in oversea.
It is about 1 and half years since the frontier officer stamped a seal on my brand new passport and said: welcome to Australia.

I arrived the beautiful and friendly city Adelaide which, as far I know, is the capital city of South Australia having about nearly 1 million people and lovely landscapes of beach,mountain and plain. Here is a really heaven for people and creature co-existing for decades.And I think here is a stop for my journey looking for a peaceful,quiet , nature and small population place. And that is the reason for the screen name of my Sina micro blog, like twitter, 我要离开 means I want to leave. I feel like tired with living in giant city that crowed with people, give more pressure from peers.Noise,traffic jam, pollution, food safety,competition from others and complicated internal personal relationship at every corner of large city.So I chose to leave the place I was born and find the place suitable for myself.It could be Australia. Why do I use "could"? Since I do not entirely understand this land. I try to explore in Australia for looking for something I intrinsically hunt for.Something may the feeling of integrating with nature, or equal and respect from others, or a broad place and long time for me to think about myself? It could something or everything.

Adelaide, for my point of view, is not a dot other than is a colon telling myself what next will be.
