简介:

  位於台风频仍的地区,又紧邻一系列的地震断层线,全球第一大高楼台北101撷取来自竹子、赛艇和跑车的概念,才不致於沦为一座17亿5千万美元的灾难。有监於大楼的高度,以及所在位置每10年都会发生地震,台北101必须兼具刚 和柔 。建筑师王重平令人跌破眼镜,特别以竹子做为大楼的结构蓝本。为了让台北101在超级风暴中依然伫立,王重平采用3500年前,由玻里尼西亚人所研发的工程解决方案,在大楼外部加上特殊的悬臂梁,以类似赛船的方式维持大楼的稳定。但光靠悬臂梁也无法阻止顶端楼层在强风中摇摆。大楼运用一般安全带的概念,在87楼到92楼之间悬吊一颗6百吨重的巨大钢球,当作平衡充油减震器的摆锤,协助分散大楼的摆汤。

简介:

  In recent years a groundbreaking new study has been released into the effects of the contraceptive pill. Research from Denmark claimed women on the pill and other forms of hormonal contraception were 70% more likely to be diagnosed with depression than those who were not. And another study has found hormonal contraception was linked to a seemingly dramatic risk of breast cancer.
  Negative headlines are nothing new for the contraceptive pill - first introduced in 1961, it has had a chequered history with early versions linked to cancer risk and life-threatening blood clots. Yet hormonal contraception remains Britain's most popular form of birth control, and today over three million women take regular doses of synthetic hormones. So should they be worried about its safety?
  GP Dr Zoe Williams gets behind the headlines in this Horizon investigation. A specially commissioned, nationwide survey reveals the areas of most concern to British women - from mental health to the risk of cancer and drop in libido. With the help of world leading scientists, Zoe finds out if these concerns are justified and by delving deep into the science around the pills side effects Horizon uncovers some striking revelations - from protecting women against cancer to increasing their risk of suicide.
