I am 40 week pregnant today. But only 50% effacement, 0.5 centimeter
dialation, negative 3 station. I am worried about the station, it is only
negative 3, I heard it may take weeks to get from negative 3 to labor. My
doctor has scheduled an induction for me a week from today. If I am still at
negative 3 station on the induction day, does that mean the baby won't be
at the position from which I can push it out by myself and I will need a c-
section?
Anybody has any idea?

I have read over dozens of studies from different countries on penis length.
My conclusion is that there is no difference between ethnic groups. A study
of 3000 Italian soldiers came up with about 13.4 centimeters. A Chinese
study of 2547 college students for entrance physical examination came up
with 13.43 centimeters. I specifically mention these two studies as they
have the largest sample sizes. Regarding Blacks, there has only been one

General guidelines for cervical dilation:
* Latent phase: 0-3 centimeters
* Active Labor: 4-7 centimeters
* Transition: 8-10 centimeters
* Complete: 10 centimeters. Delivery of the infant takes place shortly
after this stage is reached (although the mother does not always push right

The coastline paradox is the counterintuitive observation that the coastline

fractal-like properties of coastlines.[1][2] The first recorded observation
of this phenomenon was by Lewis Fry Richardson.
More concretely, the length of the coastline depends on the method used to

A 1000fps video recording the first moment of impact can make this to work:
For example, 100mph serve is 44.7 meters/second. At 1000fps, it's 4.47 centimeter per frame. Using the racket length as a reference, you can take the first 20 frames (44.7 centimeters) from when the racket hits the ball to measure the speed. If a serve can go the full length of a standard racket (27in=68.6cm) in 20 frames, it's 153mph! assuming the deceleration in such a small distance is negligible.

“至于重庆号巡洋舰就只打了20发152MM炮弹,蒋介石还骂白白浪费了我20发24生炮弹”
常校长这个炮兵上尉不识数?
24生的=152mm?
“生的”者,“centimeter”也。
哦,可能是楼主文章作者自己不懂啥是“生的”吧,以为是“不熟的”。

不是。“生的”就是centimeter的音译,厘米是也。而且常公“可惜浪费了我20发24生
的炮弹”此语可见回忆文章,不是捏造。常公是军事院校出身不会缺乏军事常识,造成
这个与实际不符合的情况我估计一是常公对重庆号的主炮口径不了解随口了;或者是回
忆文章的作者记错了。

辐射强度还是在1,000 millisieverts per hour以上
The reading of 2.9 billion becquerels per cubic centimeter of iodine-134,
one of the substances found in the water, may have been wrong, said Naoki
Tsunoda, a spokesman at the Tokyo- based utility.
The radiation level of more than 1,000 millisieverts per hour at the
building probably won’t change, he said.

TOKYO—Workers at Japan's damaged Fukushima Daiichi nuclear plant faced a
new threat Monday as they battled to keep toxic water from spilling into the
ocean, as the water's radiation levels offered the strongest sign yet that
the core of one reactor may have partially melted.
Also late Monday, plant operator Tokyo Electric Power Co. said that small
