来自主题: Biology版 - Ngago and calcium
Please consider the inhibition effects caused by high affinity unfunctional
metal cations that compete against the functional metal cations. So it's
important to do extensive dialysis after the NgAgo is purified by affinity
chromatography before one carries out the in vitro nuclease activity assay.
Never know what's going on really .
Han has to figure the reason quickly. If other labs figure it out before
they do, the credit will go to that lab.

原标题: 【推广向】介绍一下个人喜欢的里界声优(含三次元真相,慎入)
来吧里有一段时间了……潜水比较多,在此给各位前辈们请安了!
这里大学生一枚,高中时看了2011年4月新番的《我们没有翅膀》之后开始了对里界的
好奇,同时对那些声优众多的马甲非常感兴趣,算是声控一枚吧。
尽管里界声优所从事着并非什么可以登上大雅之堂的工作,其中一些人的三次元真相也
不一定堪比表界声优,但他们仍然怀着热情奋斗在为御宅族服务的第一战线。这类配音
所需要的勇气和耻度都是我们所无法想象的,希望大家对他们致以最崇高的敬意。(好
官方的语气…)
好了,废话不多说了,下面开始介绍。
有以下几点需要注意:
①以女性声优为主,同时附有三次元真相图,请不能接受的人做好瞎眼或自带屏蔽的心
理准备。
②分析他们的声线特点,部分声优可能会附上个人觉得其唱得比较好的一首歌曲。
③涉及到马甲的曝光……

Saltiness
Saltiness is a taste produced primarily by the presence of sodium ions.
Other ions of the alkali metals group also taste salty, but the further from
sodium the less salty the sensation is. The size of lithium and potassium
ions most closely resemble those of sodium and thus the saltiness is most
similar. In contrast rubidium and cesium ions are far larger so their salty
taste differs accordingly.[citation needed] The saltiness of substances is

It's very interesting result from cation. Argon's idea is pretty interesting
too, but his theory can not explain your homoPVA is soluble in hot water.
However, one point in Argon's post is very important. That's aggregation
effect. Again cation said homoPVA is soluble in hot water, but block is not.
Then there must have something to do with PIB block. Your system make a strong
segregated block copolymer system. Long range orderness can play very
important
role in your system. (Either BCC or FCC?

The most common use of platinum is as a catalyst in chemical reactions. It h
as been employed in this application since the early 1800s, when platinum po
wder was used to catalyze the ignition of hydrogen. The most important appli
cation of platinum is in automobiles as a catalytic converter, which allows
the complete combustion of low concentrations of unburned hydrocarbon from t
he exhaust into carbon dioxide and water vapor.

混搭的微信、小圈子的Path、情侣专用的Pair、只爱陌生人的陌陌……
社交网络越来越细致、精准、目的明确,我们称之为精确社交
近日Facebook上市,号称活跃用户高达9亿,让人不得不直视社交网络的急速进化。
人数上限150人的Path、被民间称为“约炮神器”的陌陌、什么都有的怪胎微信、只有情侣二人使用的Pair……
在经历了什么人都可以是网友,谁都在你的社交网络中的泛社交时代后,人们开始探索更具选择性的社交模式,正如现实生活中在没朋友的时候努力结识一切人,在朋友数量达到一定基数后则会开始挑剔。
后Facebook时代的社交网络不再盲目追求多和全,而是将人群通过地理、兴趣等划分成精确的小组,社交的目的变得更为明确,摄影控一起去采风,吃货们就得一块大吃,这样的改变也说明我们多么害怕寂寞,科幻小说中那些不需要真实接触的未来在目前看来很难实现,键盘和网线其实只是大多数人想拥有真实接触的有利工具,而已。
精确社交,这是我们创造的新词―――它指向的就是当下越来越目的明确、细分化的社交方式,不是你用哪一个社交网络的问题,而是你在不同的需求下选用不同的社交网络的问题―――当选择变得越来越多,熟人社... 阅读全帖

这恰恰说明发达国家本身是一个很蹩脚的定义。你谈到的HDI只是众多表述之一。
至于说developed是指该国的市场经济发展程度,和你说的HDI其实也不矛盾,HDI共有
三个因子,其中之一就是GDP,所以和市场经济的关联度也很大。至于说为什么市场经
济程度高GDP就高,因为GDP本身就是为市场经济量身打造的指标了。比如说,计划经济
下不会那么浪费资源破坏环境,少花钱办大事,所以类似红旗渠啊成昆铁路两弹一星,
都不会体现在GDP上。
另外呢,Stephen A. Marglin@Harvard在The Dismal Science一书里也有过类似的表述
,他就认为,现在的新古典经济学,也就是80年代主导美国乃至世界的新自由经济主义
,把经济学本身就变成了一个“市场”教,所以说,欧美发达国家里只有市场,没有社
会。原话如下:
“Economics is the enabler; economics provides the justification for
building a world based on markets. This world, our “developed... 阅读全帖

来自主题: Military版 - 看来这个陆骏没有传说的那么牛
我不认为那个多伦多的博士学位是假的,理由如下:

你这简直太多概念混乱.
decay指不稳定同位素衰变为稳定同位素.
TI的毒性是化学性细胞毒性,和同位素如何衰变没关系.

Part of the reason for thallium's high toxicity is that, when present in
aqueous solution as the univalent thallium(I) ion (Tl+), it exhibits some
similarities with essential alkali metal cations, particularly potassium (
due to similar atomic radii). It can thus enter the body via potassium
uptake pathways.[3] Other aspects of thallium's chemistry differ strongly
