意大利第一例是一月23号进入意大利,如果真的2天翻倍,那么大力现在应该有400万人
感染。如果跟武汉一样3.4天翻倍,应该有8000人。
实际意大利可能是2.8天翻倍,目前8000人确诊,2万人发病,6万人感染

Agree. That's also what I told some of the people I know. Diamond Princess
is telling us that this virus definitely can get into the air, in the
coughing droplet, aerosol or whatever you call it, otherwise there is no way
to explain its high infection rate of 19%. The US does want to learn from
China due to its arrogance; however, once the lesson is painful enough, they
will learn.

For health-care workers, the answer is obviously yes. But which masks? The

both state that doctors and nurses can use basic surgical masks when
treating COVID-19 patients, switching to the more advanced N95 respirators
if they’re carrying out procedures that might create aerosols. But such

Scientists in Massachusetts, Italy, and elsewhere are experimenting with a

COVID-19 PANIC: Masks Will Worsen the Problem
April 02, 2020
by Limin Wang
During this COVID-19 "pandemic", none of my family members use a mask. We
live in the so-called "epicenter" of Queens, New York. Although I have been
terribly injured, particularly to my central nervous system, via the
premeditated and coordinated murder attempts veiled as work "accident" and
then "diagnoses" and "treatments", I occasionally have to go outside for
things, without wearing a mask. I don't get COVID-19, and ... 阅读全帖

Global Warming Hysterics Now Blame Volcanos for Cooling

They can never admit they’ve been making this nonsense up, so now the
desperate climate change scammers are claiming volcanos are responsible for
the fact there’s been no warming since 1998.
The impact of volcanic eruptions on global warming could provide a new
explanation for the so-called “pause” used by sceptics to deny climate

来自主题: USANews版 - 变冷不是比变暖可怕吗?
其实现在仍然是一个冰河间歇的便冷周期。
变暖教只敢说比100多年前提高了1度多,但是不敢和罗马帝国时期相比。罗马时代英国
可以种葡萄,最近才刚刚温暖到可以考虑种葡萄。
另外就是红线蓝线之争,按暖教预测,100年升温得是2,3度。然而只有1度,是因为自
然本来是个变冷的过程,对冲了人为的变暖。
然而,火星的温度也提高了........
其实如果不是大冰河小冰河冻死了山顶洞人,尼人,压根也就没有非洲走出来的现代人
什么事儿了。
从地质年代来看,地球这几十亿年来一直在变冷,这也符合行星的生命周期。
而且,真正可能灭绝人类或者fallout末世景象的可能scenarios里,小行星,黄石,核
冬天。无一例外都是aerosol遮蔽阳光造成的暂时性永冬导致生物大灭绝。
而暖化? 即使变暖教预测的全部成真,也不过是癣芥之疾。连一次二战的破坏都赶不上
。最多就是灭绝个把北极熊,我看都玄。

粘接剂很好买,随便什么autozone,advanceautoparts,pepboys之类的地方就有,甚
至walmart可能也有,叫headliner adhesive之类的东西,是aerosol can的。问题在于
就算你买了也不好粘上去因为要向上用力。如果只是局部的话用这个修非常简单只要清
洁干净,喷上胶,用手按住1-2分钟就可以了。但是如果大面积脱落的话你最好把整个
headliner拆下来,倒过来放,然后再粘。工程不大但是拆headliner挺麻烦的,要拆不

当然是完成整个了,这一罐漆可是20刀呢!如果你买罐装的话一般一个1qt的是50刀,
一个2qt的是100刀,需要稀释1倍使用,所以实际上你得到的是2qt/4qt for 50/100刀
。用罐装漆比较麻烦,需要稀释+过滤,还要用喷枪,而且用的喷枪好坏直接影响用多
少油漆(HVLP的比较省漆)。我家有个HVLP的kit,插上电就能用的,不用气泵,不过
我觉得不如aerosol can好用。
