Product Description
The Kenmore 72085 oil-filled heater can save you money on your heating bill
by adding warmth to the room you’re using, so you can turn down the
household heat. As the oil inside the sealed heater heats up, it gently and
quietly warms a room up to 150 square feet. Because the heater is sealed,
you never have to refill the oil.

Secretary of Health Mary Selecky said in a news release. "The tragic events
in Japan don't pose a radiation exposure risk to people in our state. And we
urge people not to take potassium iodide or iodine pills; it's unnecessary
and could be harmful to some people." |

overcast weather is noticeably better than 70F under 200watts/m^2 or more.
In a sunny summer day here, SR will go up to 200watts/m^2 around 7:30AM, up

Small amounts of radiation headed for California, but no health risk seen
Very low levels of radioactive isotopes from the damaged Japanese nuclear
plant are expected to reach California as soon as Friday, but experts say
the amount will be well within safe limits. A network of radiation monitors
is keeping close watch. |

i need to report this to the rental office and ask them to send

Therefore I studied the English to Chinese Dictionary for a long

So i called and told the lady with confidence that the ribbon radiator

发帖数: 552 | 12 本来几乎已经决定做radiation therapy 方向的了，因为知道北美这个方向的职位多些。
但是刚刚看到首页上GE上海招工程师，X-ray 成像方面也在招人，渴望回国的想法一下
占了上风，而且，imaging 或image processing 是我这么多年来一直想做却不曾有机
会做的方向（其实以前对这个方向也不了解，只是看到 present image 的时候很炫，
不像1-D siganl 或数据处理那样枯燥乏味）。
而且最近学了点MRI和CT成像的皮毛觉得确实有意思。
刚才搜了搜，找不到国内这方面需求的具体分析，不知道国内对radiation therapy 还
是imaging的需求大（我不介意去医院还是去公司做研发）。 如果国内imaging 方面需
求也蛮大，就想做这个方向了。
有熟悉这些领域的同学么？多谢了！ |

发帖数: 236 | 13 你是刚读phd,选方向?看你说"imaging 或image processing 是我这么多年来一直想做
却不曾有机会做的方向",听着感觉你已经至少phd毕业了....个人感觉国内的医院没啥
研发吧?而且国内学校里研究MRI的都很少.radiation therapy相对imaging对数学要求
低了不少,而且很多学习imaging的同时还要学不少EE的东西.如果考虑赚钱,单讲北美的
话,radiation therapy和MRI的工资,都作为medical physcist的话差别不大,不过还是
要再次提醒下,medical physicist的board考试问题...... |

发帖数: 552 | 14 谢谢回答。
我是刚读了2个学期，现在要选方向。
不过以前有过一些其他经验。
要是回国做研发，应该还是在GE,西门子等这样的公司吧。刚刚看到主页上说GE要找x线
成像的senior engineer.
回国要是去医院，想来待遇还不如外企。
北美我倒是知道作为medical physicst, radiation therapy 比diagnostic imaging 的工作机会多
很多，而且北美医院的待遇高。
但从个人兴趣来说，我倒还是觉得imaging 更challenging & interesting。我很喜欢
傅立叶变换或者重建算法之类的东东。 Radiotherapy 真的好boring，数学上更是"
embarrassingly simple"(用我们老师的话说). 如果选radiation therapy，纯粹是因
为在北美更好找工作，在医院里。考board 倒是有思想准备，老师们天天在耳边吹这个。 |

发帖数: 1632 | 41 Here is my suggestion based on your photo.
It looks like the O-ring is wider.
1) use a wire hanger to hook the fitting so it won't drop in the radiator.
2) use a plier to pull out the O-ring out.
3) you should be able to pull 50% of the fitting up with the wire hanger.
4) you are on your own because I am not sure if there is enough fitting
for you to pull it with with a plier or do you have anything L shape tool
that is strong enough to pull it up
