Why Is the Linking C−C Bond in Tetrahedranyltetrahedrane so Short?
Organic Letters, 2006[structure: see text]. The block-localized wave function (BLW) method has been employed to probe the origin of the very short linking C-C bond (1.436 A) in tetrahedranyltetrahedrane. Computations show that the vicinal hyperconjugative interactions between the two tetrahedranyl groups is stronger than the conjugation in butadiene, and if there were no ...

The short-circuit characteristics of D-C generators
Electrical Engineering, 1946KNOWLEDGE of the short-circuit characteristics of d-c machines is an essential factor in the design of d-c electric systems having a large low-voltage machine capacity concentrated in a small area. This information is particularly important in the design of systems such as those encountered aboard ship where circuit breakers, fuses, relays, and other ...

A short synthesis of C‐glycosyl pyrazoles and pyrroles
Journal of Heterocyclic Chemistry, 1995AbstractThe sodium salt of TOSMIC reacted with (E)‐3,4,5,6,7‐penta‐O‐acetyl‐1,2‐dideoxy‐1‐C‐nitro‐D‐galacto‐ (1) and ‐D‐manno‐hept‐1‐enitol (2) to give 3‐(D‐galacto‐ (3) and 3‐(D‐manno‐penta‐O‐acetylpentitol‐1‐yl)‐4‐nitropyrrole (4), respectively. Compound 1 reacted with diaryl nitrile imines, affording 1,3‐diaryl‐4‐(1,2,3,4,5‐penta‐O‐acetyl‐D‐galacto ...

Hepatitis C is a rapidly developing area of medicine – diagnostic tools are ever more refined, and entirely new treatments and treatment strategies are arriving, with more on the horizon. And because the virus affects such a large and varying population – up to 170 million at last count – we think it is important to have a pocket reference especially ...

Cytochrome c oxidase: A short review
Inorganica Chimica Acta, 1983For some years now research on cytochrome c oxidase (EC1931) has been gaining momentum [see 1–3 for reviews]. Largely this is due to the important role this enzyme plays in cellular respiration but also it reflects the availability of new and sophisticated techniques which afford the opportunity of making rapid and significant progress in our ...

C-rater: Automated Scoring of Short-Answer Questions
Computers and the Humanities, 2003C-rater is an automated scoringengine that has been developed to scoreresponses to content-based short answerquestions. It is not simply a stringmatching program – instead it uses predicateargument structure, pronominal reference,morphological analysis and synonyms to assignfull or partial credit to a short answerquestion.
