China Coal Consumption Linked To Global Cooling
WASHINGTON -- Scientists have come up with a possible explanation for why
the rise in Earth's temperature paused for a bit during the 2000s, one of
the hottest decades on record.
The answer seems counterintuitive. It's all that sulfur pollution in the air

Sulfur particles in the air deflect the sun's rays and can temporarily cool

Steps to know the symptoms of Chinese drywall
Step 1
One of the first signs of Chinese drywall is a strong sulfur smell, similar
to the smell of rotten eggs. Lots of people in new homes pass this off as
smell from the paint, or new carpeting, etc. If you smell sulfur in your
home, you should consider a method of testing. See the resources section for
more. Also, just because your home doesn't smell like sulfur doesn't mean
you don't have Chinese drywall. In cooler environments, Chinese drywall

栀子花需要酸性土壤:
Lowering the soil pH to make it more acid
If your soil needs to be more acidic, sulfur may be used to lower the pH if
it is available. To reduce the soil pH by 1.0 point, mix in 1.2 oz of ground
rock sulfur per square yard if the soil is sandy, or 3.6 oz per square yard
for all other soils. The sulfur should be thoroughly mixed into the soil
before planting. Sawdust, composted leaves, wood chips, cottonseed meal,
leaf mold and especially peat moss, will lower the soil pH.

The cooling mechanism is fairly straightforward. Sulfur dioxide is

转华人科学网。http://www.sciencenets.com/thread-1618-1-1.html
谢灿的文章《A magnetic protein biocompass》终于在《Nature Material》上发表了
,首先恭喜一下作者的文章发表。这也意味着,我们首次有机会比对谢灿与张生家的文
章,对两人关于“抢发”文章的争议做出有一个客观评价。
首先,我来总结并点评一下谢灿的文章所描述的研究成果。
总结:
文章回顾了目前已经提出的动物利用磁场定位的机理。第一,光感蛋白Cryptochromes
(Cry)可以在光线刺激下对地磁场产生反应,而缺失这个蛋白的果蝇会失去磁感应的
能力,因此Cry被认为对动物磁感应起重要作用。但是Cry本身不具备磁极性,因此不具
备指南针的功能。第二,由动物体内具有磁性的矿物质所形成“magnetite”被认为是
另一个磁感应的机制,这些磁性矿物质已经在多种动物的器官中被发现,但是有研究指
出这些矿物质与磁感应无关。
基于以上两点,谢灿在文章中提出一个猜想——应该存在一个具有磁性的蛋白,能与
Cry结合,并且具有磁受体的功能;谢灿将这个假设中的... 阅读全帖

of iron (32.1%), oxygen (30.1%), silicon (15.1%), magnesium (13.9%), sulfur
(2.9%), nickel (1.8%), calcium (1.5%), and aluminium (1.4%); with the
remaining 1.2% consisting of trace amounts of other elements. Due to mass

The TripleFlex is just a food supplement, like multiple vitamin etc., not a
drug so its effectiveness on arthritis is suspicious!
1. check this out: (about MSM)
"No published research studies link MSM to any of the health claims made by
its marketers. Sulfur needed in human metabolism comes from dietary protein.
MSM supplements probably make little or no contribution to the body's sulfur
requirements. Thus there is no good reason to use MSM supplements."

前面有网友在看完“潘伟平——长期迫害中国大陆学者、官司缠身、学术造假,营
造‘血汗实验室’,这样的人也配入选中组部千人计划?”一文后说,“就事论事,这
是在指责潘伟平在‘德’方面的问题,好像‘才’方面没提到。那么国家‘千人计划’
在德方面有哪些要求?好像没有嘛。”这位网友,谢谢你的回帖。下面我们提到潘伟平
“才”的一面。首先让我们回顾一下“千人计划”的基本要求。
“千人计划”是中国目前最高层次的海外人才引进计划。国家从2008年起,用五到
十年,引进一批战略科学家和领军人物回国创新创业。国家重视程度之高,投入力度之
大,远远超过“长江学者计划”。
“千人计划”设立四个平台,其中为高等学校和科研机构引进的海外高层次人才,
除基本要求外(年龄、学历、职称等),还需具备下列条件:
具有世界一流的研究水平,近五年在重要核心期刊上发表具有重要影响的学术论文;
获得国际重要科技奖项,掌握重要实验技能或科学工程建设关键技术。
潘伟平宣称的文章很多,让我们一一梳理,看他是否符合“千人计划”的条件。所

What you describe, the experience of abnormal smells or odors is common, but
not well understood and the odor of sulfur or rotten eggs is one of the
more common of these. These sensations are believed to most often originate
in the central nervous system
, rather than in the nose or other structures. However recent studies
suggest that in some instances, the odor may originate from diseased nerve
endings in the nose or

我喜欢自然景观,从加州北部到西雅图有几个国家公园一直都想去看看,可是作为屌丝
总是既缺时间又缺money, 不过在五月下旬还是最终决定去一趟。去掉两头乘机时间,
自己驾车大约11天半,从三藩出发转一圈回来,行程约4700miles。 路线是: SFO ->
金门大桥&花街&渔人码头 -> 加州1号路(Monterey-Cambria) -> Sequoia & Kings

Lava beds NM -> Crater lake NP -> Portland (Cannon beach & Columbia river
Gorge) -> Mt rainier NP -> Olympic NP -> North cascades NP -> Florence sand
