Seven new polyketides, named tanzawaic acids R-X (1-6, 11), along with seven known analogues (7-10 and 12-14), were isolated from Penicillium steckii HDN13-279. Their structures, including the absolute configurations, were elucidated by NMR, MS, X-ray diffraction, circular dichroism (CD) analyses and chemical derivatization. Five compounds (2, 3, 6, 10 and 12) significantly decreased the oleic ...

Two methods of triglycerideblank measurement were critically investigated. For 38 samples a mean blank value of 7.2 mg/dl was obtained when the blanks were measured by replacingthe saponifying reagent with 80% isopropanol. For the same samples, consistently higher blank values were obtained (mean = 18.3 mg/dl) when these were determined by the Kessler-Lederer method. It is suggested that, when ...

Given an uncountable regular cardinal κ, a partial order is κstationarily layered if the collection of regular suborders of P of cardinality less than κ is stationary in Pκ(P). We show that weak compactness can be characterized by this property of partial orders by proving that an uncountable regular cardinal κ is weakly compact if and only if every partial order satisfying the κ-chain conditio...

To assist Java programming educations, we have developed a Web-based Java Programming Learning Assistant System (JPLAS). JPLAS provides fill-in-blank problems for novice students to learn Java by filling blank elements composed of reserved words, identifiers, and control symbols. In this paper, we propose a graph-based blank element selection algorithm to select as many blanks as possible such ...

In the last number of The Psychological Clinic I explained the purpose of the blank, the general arrangement of the items, and the method of grading employed, especially the method of grading mentality. To assist me in the further presentation of the items of this blank, I have reproduced an actual blank partially filled out, which will be found on the next page. At the top of the blank is the ...

Einen Problembereich im Verkehrssektor stellen Tourenplanungsprobleme dar. Diese entstehen, wenn Personen oder Güter von einem Transportmittel zu verschiedenen Orten gebracht und/oder abgeholt werden müssen. Im Allgemeinen geht es darum Aufträge zu erfüllen und die Anzahl der nötigen Touren sowie die Gesamtstrecke zu minimieren (Christofides et al. (1979)). Ziel dieser Arbeit ist es ausgewählte...
