Panepophenanthrin, from a Mushroom Strain, a Novel Inhibitor of the Ubiquitin-Activating Enzyme

Screening for inhibitors of the ubiquitin-proteasome pathway, considered to regulate important cellular events and linked to serious diseases as well, led to isolation of a new compound, panepophenanthrin, from the fermented broth of a mushroom strain, Panus rudis Fr. IFO 8994. This is the first inhibitor of the ubiquitin-activating enzyme, which is indispensable for the ubiquitin-proteasome pathway. The structure of panepophenanthrin was determined by NMR and X-ray crystallographic analyses as 1,3a,10-trihydroxy-10c-(3-hydroxy-3-methylbut-1-enyl)-5,5-dimethyl-1,2,3,3a,5,5a,8,9,10,10a,10b,10c-dodecahydro-4-oxa-2,3,8,9-diepoxyacephenanthrylen-7-one.

LAMBDA: A quick, low cost layout design system for master-slice LSI s

This paper describes an automatic/interactive layout design system for designing master-slice LSI chips, which places function blocks and gives wiring patterns on the chip. Since 100% routing is essential for master-slice layout design, it is urgently required to establish a strong CAD system, which significantly reduces the design time. The LAMBDA system has been developed to achieve complete net connectivity in as short a design time as possible, where efficient automatic procedures are implemented as well as highly interactive functions. The system adopts two-level hierarchy algorithms for placement and routing problems. Highly interactive functions are realized by exploiting human intelligence and the computer's high speed processing.

ANALYTICAL EVALUATION FOR CRACK PROPAGATION OF RC BEAMS

RCはり部材に対する曲げひび割れ進展挙動について,クリープ,収縮,コンクリートの硬化過程に伴う材料特性の変化と,鉄筋の付着性状を考慮した3次元有限要素解析を用いて解析的に評価を行った.鉄筋の付着性状を考慮することにより,荷重増加によるRCはり,PRCはりのひび割れ性状およびひび割れ幅について評価できることが示された.また,時間依存挙動を考慮することにより,持続荷重による全体挙動およびひび割れ進展挙動を,強度による材料特性の違いに依らず,妥当に評価できることが示された.さらに,本解析手法を用いて,乾燥収縮量や自己収縮量,乾燥領域,クリープがひび割れ進展挙動に及ぼす影響を検討した.

ANALYSIS OF COMPRESSION FAILURE OF CONCRETE BY THREE DIMENSIONAL RIGID BODY SPRING MODEL

3次元剛体バネモデルによりコンクリートの圧縮破壊挙動を定量的に再現することを目的とし,同手法の構成モデルの検討と材料パラメータの同定を行った.その結果,垂直バネの引張側に引張軟化挙動を,圧縮側に逆S字形の非線形挙動を,せん断バネにモール・クーロン型の降伏基準と軟化をモデル化することにより,1軸圧縮下におけるコンクリートの軟化・局所化挙動および高拘束圧領域に至るまでの多軸効果による強度増加,体積変化挙動を妥当な精度で再現できることが分かった.

Extended operation of reactor-scale fusion fuel loop under US-Japan collaboration

Tritium Systems Test Assembly (TSTA) in the Los Alamos National Laboratory is a reactor-scale fusion fuel processing loop and is operated by the Japan Atomic Energy Research Institute (JAERI) and the USDOE under the collaboration. An extended experimental campaign of the TSTA loop was performed with 100 grams of tritium in April-May 1992 in order to simulate a steady-state fusion fuel processing for 25 days. Continuous processing of simulated plasma exhaust (DT and H mixture, He, CH/sub 4/ and N/sub 2/) was successfully demonstrated. Impurity processing was successfully tested by two different techniques. US developed Fuel Cleanup System (FCU) purifies DT by cryogenic molecular sieve beds and decomposes tritiated water by Magnesium beds. Japanese developed J-FCU is based on purification by permeation through palladium alloy membrane and vapor electrolysis with a ceramic electrolyte cell. Isotope Separation System was stably operated with four interlinked columns and continuously produced pure tritium and deuterium stream while exhausting protium impurity. Real-time analysis in the ISS process was demonstrated with the laser Raman Spectroscopy. The result demonstrated the safe and stable operation of reactor-scale fusion fuel loop in a steady state.
