Stable ideals in Gorenstein local rings

AbstractLet (R,m) be a Gorenstein local ring. We give a criterion for a stable m-primary ideal of R to have the Gorenstein associated graded ring. Using this criterion, we give various examples of Gorenstein associated graded rings

Diacetyl as Acetyl Donor

Diacetyl can serve as an acetyl donor for the forlnation of citrate and the acetylation of sulfanilamide in the dog heart homogenate. Diphosphothiamine and coenzyme A are essential for these reactions.</p

Selective Field-Ionization Electron Detector at Low Temperature of 10 mK Range (NUCLEAR SCIENCE RESEARCH FACILITY?Particle and Photon Beams)

Combined with a dilution refrigerator, selective field-ionization detection system with a channel electron multiplier optimized at 10 mK-range temperature was developed. The detection efficiency of the ionized electrons from the n~110 Rydberg states of Rb is 98% at the lowest achieved temperature of 12 mK

Cholecystokinin receptor antagonist, loxiglumide, inhibits invasiveness of human pancreatic cancer cell lines

AbstractRecently, cholecystokinin has been reported to be important in regulating the growth of pancreatic cancer. We investigated the effect of loxiglumide (LXG), a cholecytskinin receptor antagonist, on the invasiveness of two human pancreatic cancer cell lines. Cells were treated with LXG for 24 h, and examined in the invasion assay. The expression and activity of MMP-9 in supernatants from cancer cells were analyzed by Western blotting and zymogram. Interestingly, the invasiveness of cancer cells and expression of MMP-9 were decreased by LXG in a dose-dependent manner. LXG may be a useful therapeutic agent against pancreatic cancer

Singular Derived Categories of Q-factorial terminalizations and Maximal Modification Algebras

Let X be a Gorenstein normal 3-fold satisfying (ELF) with local rings which are at worst isolated hypersurface (e.g. terminal) singularities. By using the singular derived category D_{sg}(X) and its idempotent completion, we give necessary and sufficient categorical conditions for X to be Q-factorial and complete locally Q-factorial respectively. We then relate this information to maximal modification algebras(=MMAs), introduced in [IW10], by showing that if an algebra A is derived equivalent to X as above, then X is Q-factorial if and only if A is an MMA. Thus all rings derived equivalent to Q-factorial terminalizations in dimension three are MMAs. As an application, we extend some of the algebraic results in Burban-Iyama-Keller-Reiten [BIKR] and Dao-Huneke [DH] using geometric arguments.Comment: Very minor changes, 24 page

桑抹茶の利用法に関する研究 〜ココアとの組み合わせによる抗酸化活性の変化について〜

In order to develop a new utilization method of mulberry leaf powder (MLP), this study tried to combine MLP with cocoa drink and measured antioxidant activity (AA) of combined sample solution expecting a synergistic effect. Contrary to expectation, AA of combined solutions was decreased with increasing in combined quantities of MLP by comparing with AA of each sample solution of MLP and cocoa drink. Reason of this result and effects of combination of MLP with cocoa drink on other functionalities are not yet known, so we cannot yet conclude whether this combination was not good

On the support of general local cohomology modules and filter regular sequences

Let R be a commutative Noetherian ring with non-zero identity and a an ideal of R. In the present paper, we examine the question whether the support of Hn a (N;M) must be closed in Zariski topology, where Hn a (N;M) is the nth general local cohomology module of nitely generated R-modules M and N with respect to the ideal a
