在amazon买了那个DB2, 结果收不到ABC的,其它FOX, CBS,NBC那些都是很好HDTV效果.
但我是主要想用它看ABC的NBA playoff. 一查原来ABC搬到VHF去了,而这个DB2是
UHF only. 没办法,查了一下local老外的forum,说home depot的那个GE antenna不错.
是UHF/VHF/FM,能收到ABC.
就去扛了一个回来, 好大一个.张开有58". 是outdoor的,不过我估计放在靠窗口应该
也可以,我实在是懒得跑到屋顶或者attic去装了.
接好电视,结果又是只能收到除了6-11那些台, ABC在8台,还是收不到.
这个不是和DB2一样吗...
然后又去HD买了个GE的indoor VHF/UHF的回来. 这个是有两根长天线的,应该是用来
收VHF的. 结果还是只能收到除了ABC外的所有台.也就是还是收不到VHF的那些台.
本来是查过的,ABC在我这里信号是绿色的,应该是强信号,结果搞了三个天线,还是
收不到,真是被打败了.
这个用天线收VHF的信号还是买些什么啊,我相信那个GE的58"的天线是应该能收到
VHF的信号的.

标 题: Fever medicines 'given to children too readily'
发信站: BBS 未名空间站 (Tue Mar 1 06:08:50 2011, 美东)
Fever medicines 'given to children too readily'
Health News, The Telegraph, Feb 28.
Parents should not dose up children who have a simple fever on regular
spoonfuls of paracetamol and ibuprofen, according to doctors who say that
doing so could put them at risk.
A misplaced "fever phobia" in society means parents too frequently use both
medicines to bring down even quite slight temperatures, say the
paediatricians, who warn that children often receive accidental overdoses as
a result.
A high temperature is usually the body's way of fighting an infection,
according to advice issued today by the American Academy of Pediatrics, so
to bring it down could actually lengthen the time a child suffers.
Doctors too readily advise parents to give the medicines, known collectively
as "antipyretics", according to the Academy.
The advice comes after a study indicated that children given paracetemol
before 15 months were more than twice as likely to develop asthma by the age
of six as those not given it.
Writing in a clinical report on fever and the use of paracetamol and
ibuprofen in children, the authors warn: "Combination therapy with
acetaminophen [paracetamol] and ibuprofen may place infants and children at
increased risk because of dosing errors and adverse outcomes, and these
potential risks must be carefully considered."
Doctors, they write, should begin "by helping parents understand that fever,
in and of itself, is not known to endanger a generally healthy child".
They explain: "It should be emphasized that fever is not an illness but is,
in fact, a physiologic mechanism that has beneficial effects in fighting
infection."
It slows the spread of bacteria and viruses, enhances white blood cell
production, and "actually helps the body recover more quickly from viral
infections".
Despite this, they say: "Many parents administer antipyretics even though
there is either minimal or no fever."
Half consider it to be a fever even if their child's temperature is not
higher than 38C (101.4F), they report.
Many doctors are happy to advise parents to give paracetamol and ibuprofen
alternately - known as combination therapy - believing side effects are very
rare and minimal.
But the Academy warns: "Unfortunately as many as one-half of parents
administer incorrect doses."
A frequent error is giving children adult-sized doses, while children who
are small for their age can also receive doses that are too high even if
their parents follow box instructions based on age alone.
In Britain, the National Institute for Health and Clinical Excellence (Nice)
advises that the use of anti-pyretics "should be considered in children
with fever who appear distressed or unwell".
However, they "should not routinely to used with the sole aim of reducing
body temperature in children with fever who are otherwise well".
Similarly, "paracetamol and ibuprofen should not routinely be given
alternately to children with a fever", although it states this approach "may
be considered if the child does not repsond to the first agent."
The guidance also states: "The views and wishes of parents and carers should
be taken into consideration.".
Children's paracetamol solutions like Calpol and ibuprofen solutions like
Nurofen for Chilren are sold over the counter in chemists. Recommended
dosage quantities vary by age.
There are different strength solutions for different ages, meaning it is
possible for parents with different aged children to mix up which they are
giving.
According to the British National Formulary, which GPs consult when
prescribing or advising on medication, children should receive no more than
four doses of the right amount of paracetamol in a 24-hour period, and no
more than four doses of ibuprofen.
Both medications have potential side effects, notes the Academy.
Paracetamol has been linked to asthma, although "causality has not been
demonstrated", while there have been reports of ibuprofen causing stomach
ulcers and bleeding, and leading to kidney problems.
Children who are dehydrated, have heart problems and existing kidney
problems are "at the greatest risk of ibuprofen-related renal toxicity",
they write.
"Questions remain regarding the safety" of combination therapy, say the
authors, led by Dr Janice Sullivan of the University of Louisville Pediatric
Pharmacology Research Unit and Dr Henry Farrar of the University of
Arkansas.
"The possibility that parents will either not receive or not understand
dosing instructions, combined with the wide array of formulations that
contain these drugs, increases the potential for inaccurate dosing or
overdosing," they caution.
"Finally, this practice may only promote the fever phobia that already
exists."
Rather than focusing on temperature alone, doctors should advise parents to
look out for signs of serious illness, make sure their child is drinking
enough, and "advocate a limited number" of doses of medication.
Dr Clare Gerada, chairman of the Royal College of GPs, said the two
medications should be used "only to help a child be comfortable, and not to
chase down a temperature."
However, she said: "I don't think we over-prescribe anti-pyretics and I don'
t think parents give them too readily."
She added: "I think they have their place. The younger the child the more
cautious you have to be."
She did not think that giving ibuprofen and paracetamol together was more
likely to lead to increased dosing errors, saying: "In my experience of 20
years as a GP, parents are usually pretty careful."
"I think the most important thing to be worried about is keeping medicines
out of the reach of children, because some of them taste quite nice."
They could also give "a false sense of security" in depressing a high
temperature with a more serious underlying cause than a mild infection, she
said.

提起我老爸我现在都不想说他了,简直就是个大烟囱,大烟枪。我老爸抽烟的烟龄
比我都大,他每天就是不停的抽烟,上厕所也抽,睡觉之前也抽,干活也抽,一天抽一
包烟都不止。为了他抽烟这个事情我跟老妈没少说他,他要是买烟我总是会给他藏起来
,这样想着他肯定就不会再抽了。
没想到人家根本就不在乎另外又买了好几包,你说气不气人。为了他戒烟这个事情
我都不知道跟老妈想了多少招了,但是全部都以失败告终了。
我们不让他抽烟好像跟要他的命一样,我们不让他抽烟也是为了他好,毕竟老爸现
在年龄大了,身体的抵抗力也越来越差了,要是按照他这个抽烟的进度哪一天真指不定
身体会出现啥问题呢?到那个时候指不定就大眼瞪小眼了,自己后悔了。
真不知道这个烟有啥好抽的,对身体一点好处都没有。你说要是对身体有好处那
你抽我们肯定不会说,关键这对身体全部都是不好的地方。奉劝那些还想多活几年的趁
早就把烟戒了,否则以后身体出问题了有你们后悔的时候,千万不要大意。

midi guitar?
介个能行么,不会只能用单音吧?
不是得要那种专门的pick up么,就是pick up分成6段,每根弦一个pick up的。

先试试看把天线放到阳台之类的户外,方向要调整好。
我看的论坛上面,很多人都说,什么类型的天线差别不大,差别比较大的是
户外还是室内,有没有信号加强器。
P.S.我这里什么室内用有加强器的天线,除了CBS(也是VHF的),大部分台都能收到。
要收CBS,USB HDTV tuner自带的那根小铁杆就可以了,但是要放到阳台上面,
室内就是不行。

呵呵,我開始也想是需要單獨的pick up可是看看評論好像還不錯,只帶midi激發的輸
出,通過振動音高頻率控制應該沒問題。

可以试试这个 http://members.shaw.ca/hdtvantenna/
我自己做了一个,效果非常好。用两根粗铜条就能搞定。你可以把一根同调的长度弄到
ABC波长的1/4, 专门为ABC优化。http://en.wikipedia.org/wiki/North_American_broadcast_television_frequencies 上有频道和频率的对照表。

室内确实比较麻烦,两个方案:
1. Winegard FreeVision FV-HD30 收high VHF和UHF,可挂墙上,比较容易
找到信号强的地方
2. 买一个VHF/UHF joiner,不是splitter,再买一个专收VHF的天线,Terk TV-1
不错。

没有。
你这个一定是单音的,呵呵
midi guitar解决方案我试过很多了,目前用
Godin Freeway SA + Roland GR-33
你search 一下youtube,很多GR-33的demo,还不错,里面的音源相当于Roland JV系列
合成器,比较老。
当然如果有更好的音源,可以用Roland GI-20,无音源,midi out + USB,可以驱动软
音源

以前我有个很老的ROland GI-10
可以接单独的6个pickup的特殊pickup输出midi
也有一个1/4"口接吉他,话筒或者任何东西,就是把声音转成midi信号。弹琴必须十分
干净,否则太多ghost notes

其實我覺得midi guitar單音就夠了,我曾經在我的pg380上彈過吉他的掃弦等多音技巧
,幾乎沒有辦法用,所以至少對我來説我就是想再弄一個midi轉接器彈solo,等於增加
不同的音色。
你老兄用midi吉他怎麽玩?玩些什麽?

这种单音如果玩Pad,弦乐什么的,够了
我拿那个来整钢琴,sax,什么的,做backtrack,一个个敲midi太慢,这样比较快一些
,而且一些midi parameter什么的自动就进去了。。。不会keyboard的痛苦啊
