練習不足がたたり10kmレースは昨年より1分19秒遅くなりました。このままでは10kmを1時間以内に走れるのは来年位までの様です。昨日は忙しくてラグビーワールドカップの決勝戦を見る暇がありませんでしたが、私の予想通りNZが勝ちましたが、たった1点差とは予想外です。早く録画を見たいが今週末までに見る時間ができるかな。
さて、Reader's Digest 9月号のBack to Natureと題された記事は、ライト兄弟が飛行機を開発するのに鳥を参考にしたり、スイス人技術者が "picked burrs off his clothing" した時にVelcroが誕生した様に、自然を観察する事で生まれた技術の特集でした。
鮫のウロコの研究から院内感染を減らす材料が作られました。
Can sharks reduce hospital infections?
Fouling - the slimy growth that collects on ships' hulls - is an expensive nuisance to shipowners and is often remedied with potentially harmful copper-based paints.
...
Brennan noticed that the microscopic toothlike pattern of their scales prevents algae and barnacles from sticking to their bodies. Using that insight, he created Sharklet, a pattern that mimics shark scales and reduces fouling by 85 percent, as compared with smooth suraces. But there's more! Dangerous bacteria can't adhere to Sharklet either.
"fouling" は初めて見る単語です。記事の冒頭に意味の説明がありますが、一応辞書での説明も見ます。
・Merriam-Webster's Online Dictionary: deposit, incrustation (fouling on a ship's bottom)
・Wiktionary: (uncountable) The adhesion of a foreign material onto a surface, especially so as to reduce its functionality
・Dictionary.com: an encrusted deposit, especially on a submerged object, as the hull of a ship.
RDの記事では使われていませんでしたが、"fouling" を防ぐ材料、方法は "anti-fouling" と言えます。
The best protection against a build-up of weed is a good healthy coat of anti-fouling or bottom paint.
