Deciphering Small Molecule Diffusion Parameters Across Light Responsive Polymersome Membranes
Advanced Functional Materials, EarlyView.Light‐responsive polymersomes bearing donor–acceptor Stenhouse adducts (DASAs) enable programmable control over small‐molecule transport across synthetic membranes. By systematically varying DASA density, an optimal functionalization regime is identified that maximizes light‐gated permeability.

A Study of Self-sufficiency of Food in Japan.
JOURNAL OF THE JAPANESE ASSOCIATION OF RURAL MEDICINE, 2001 日本のエネルギーベース食糧自給率は40%前後まで低下している。取手市の住民を対象としたアンケート調査では, 成人の83%, 高校生の45%, 中学生の54%がこの低い自給率を「心配」と答えた。世界の食料生産は地球温暖化の影響もあり, 今後需要に応じられるか不安である。日本周辺の政情も安定していないから, 上一時的にせよシーレーンが確保できず, 輸入が途絶えるおそれがある。このように食糧自給率低下は国の基本的課題として, 討論されるべきだが, 日本のマスメディアはほとんど取り上げようとしない。農業政策の不合理と非難するが, 危機管理上どう対処するのか示すことはない。1993年以来, GATT, WTOで日本はコメの自由化を迫られ, 譲歩した結果, ミニマムアクセス, コメの関税化を承認した ...

Exploring the organic agriculture practice in Mexico: an opportunity for small-scale farmers to feed themselves [PDF]
We examine how organic farming practiced by small farmers in rural zones in Mexico could build a self-sufficient food system. We hold the hypothesis that the promotion of the local consumption of organic produce is an alternative to strengthen the local ...

Advanced Functional Materials, EarlyView.Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.
