一点不同的看法:初学者身体前倾是不正确的姿势,upper boday should be pretty
much over your edge but not inside of your turn. It is a "bad habit" though
in that it will get you into trouble at higher speeds and on steeper terrain
. The reason is due to centrifugal force; that force that tends to pull you
to the outside of the turn at speed. How this negatively affects you is this
leaning adds a ton of centrifugal force to your board`s edge in a tun. This
tends to want to push your board out away from you in a turn, caus

我觉得这个东西会毁了膝盖
高速carving的时候重心移到两腿外是因为有centrifugal force平衡
在没有centrifugal force的时候重量全吃在膝盖上,非得把mcl扭断不可

This Kiss(Faith Hill)
I don't want another heartbreak
I don't need another turn to cry
I don't want to learn the hard way
Baby, hello, oh, no, goodbye
But you got me like a rocket
Shooting straight across the sky
It's the way you love me
It's a feeling like this
It's centrifugal motion
It's perpetual bliss
It's that pivotal moment
It's impossible
This kiss, this kiss (Unstoppable)
This kiss, this kiss

you can use smaller centrifuge tubes at a higher G rate.
Or, try the Oak Ridge centrifuge tubes. They can be used up to 50,000 g.

Thank you guys.
I use PGEX2T vector so GST is on the N-terminus.
I normally do 100ml culture size. Here is how I did this:
1. small culture of the bacteria from glycerol stock O/N, about 6-8ml.
2. transfer the small culture to 100ml 2xYTA medium in the next day morning
, shaking at 300rpm, 37degrees.
3. it ususally takes about 1hr 40min - 2 hrs to have an OD600 around 0.75.
4. add IPTG (stock 100mM) 100ul to get a final concentration of 0.1mM.

离心机肯定在二战的时候已经成熟了,造原子弹不是要这玩意嘛
English military engineer Benjamin Robins (1707–1751) invented a whirling
arm apparatus to determine drag. In 1864, Antonin Prandtl invented the first
dairy centrifuge in order to separate cream from milk. In 1879, Gustaf de
Laval demonstrated the first continuous centrifugal separator, making its
commercial application feasible.

1. centrifuges,从大约19,000减少到6,104,今后十年,只能有5,060个用来提纯铀。
2. Uranium enrichment,只能提纯到3.67%,协议有效期15年。伊朗同意15年以后不再
建设新提纯设施。另外,伊朗同意在15年内把10,000 kg存储减少到300 kg。
3. Breakout time,伊朗获得制造一枚核武器材料的时间从2到3个月延长到一年。
4. Fordow facility,Fordow facility至少15年停止提纯铀,并且不能有裂变材料。
5. Research and development,伊朗可继续提纯的R&D,但必须在一年的breakout

后面两个不重要。
6. Inspections,
7. Sanctions lifted,
这个协议基本上是限制伊朗获得核武器的时间和数量,而不是禁止研究,所以以色列的

来自主题: Automobile版 - 请问涡轮增压到底有啥好处?
好像不对吧?supercharger的efficient应该与转速没太大关系的,应该是crankshaft
转的越快,supercharger的output越大。根据howstuffwork的说法,现在的机械增压都
是Centrifugal supercharger,应该是在高转速段比turbo更efficient。

Congratulations to both of you, easterlilium and Sunnyday!

offer you up to 30% discount for purchasing equipments or consumables, or

这个还得看你在什么学院里,如果是文理学院,会给的少一些,如果是医学院
会多一些。
另外,假如你现在还没有拿到offer的话,不宜狮子大开口,
Morphine 和我的情况都是已经拿到口头offer 了才列那个单子的,所以我
以为你的情况也是这样。
如果连面试都还没有进行的话,要尽量谨慎,列一些你肯定用得到的仪器,
最后大概在30万左右就行了再加上两年的技术员工资。大概40~50万吧,
对于公立学校的文理学院来说,是个正常开价。等你最后拿到offer 后,还有
一次讨价还价的机会的。那个时候你可以借口说你当时以为系里已经有了某个
仪器,但是实地访察后发现该仪器 太旧/使用的人太多/不存在,所以要
重新买,云云。
然后对于价钱,直接打电话给公司,说你正在和学校negotiate, 需要这些价钱(大概
价钱)。我当年就给三个公司打了电话:
VWR (general equipments), Beckman (centrifuge), API/Deltavision (microscope).
还有一个方法就是直接google xxx instrument for sale
会搜到一些卖二手仪... 阅读全帖
