ホットなアイデアをクールに活かす

スフェロイド灌流培養装置「PASCL」の培地保冷ユニットを作りました。パウチに入れた培地を冷やしておき、マイクロポンプでPASCLに灌流させます。

5℃に保冷中(温度は任意に設定可能)

培地はパウチに入れてバネで固定し、背面に組み込んだペルチェ(電気を流すと冷たくなる半導体)で冷却します。マイクロポンプも組付けてあってタイミングに合わせて培地を送り出します。後はタイマー基板をつけて自動培養できるように仕立てていきます。デザインはもう少し凝ったほうが良さそうですので、化粧板で奇麗にまとめることにします。

技術的には何と言う事は無いものですが、ここまでコンパクトにまとめたものは今までありそうでなかったアイデアグッズです。しかもPASCLとはチューブで繋げているだけですから、このユニットを独立させて色々な培養装置に使えそうです。今は大学の研究活動も制限されている状況なので、いったんセットしたら1週間ほったらかしにしておけるのは大きな利点です。汎用パーツを組んだだけですから値段も安価です。

緊急事態宣言下では自宅に籠ってせっせと工作。でもコンセプトをしっかりさせれば立派に“使える”デバイスとなりそうです。これぞ趣味と実益を兼ねたおうちビジネス?!

    Because of the ninth inning and extra-inning “dilemmas” for home team backers, home teams win several more one-run games than visiting teams. Home teams win one-run games 17% of the time, while visitors win one-run games just 11% of the time. Thus, if one is backing a home team favorite at -1.5 runs, one must be sure they will jump out to a big lead early.

    Northern Ireland, which has won more medals in boxing than in any other sport, sent a 12-man squad to Birmingham, the second-largest contingent, surpassed only by England (14). Five members of the NI team (3 men; 2 women) won gold medals including 29-year-old featherweight Michaela Walsh and her younger brother Aidan Walsh, a 25-year-old light middleweight. Michaela and Aidan were Olympians last year, the first brother-sister combo in Olympic boxing history, but failed to medal.

    Undercuts never fail to give just the right amount of edge to any haircut. However, if you do not want to commit to an actual undercut, you can try a faux one as shown above. Here the hair is longer at the crown, while the sides and back are shorter (though still longer) than an undercut. The short hair on the sides and at the back are blended to the head with a gel. This can create the illusion of an undercut that even a dreamy pixie can look tough with. Katy Perry carries this look off beautifully with choppy hair at the crown. 63.
