Alkyl nitrites readily transfer nitrosonium into calixarene-based synthetic nanotubes thus offering a mild, effective and precise method to fill them.

In this paper we investigate the additional storage overhead needed for a parallel implementation of nite element applications. In particular, we compare the storage requirements for the factorization of the sparse matrices that would occur on parallel processor versus a uniprocessor. This variation in storage results from the factorization ll-in. We address the question of whether the storage ...

Meta-analysis collects and synthesizes results from individual studies to estimate an overall eeect size. If published studies are chosen, say through a literature review, an inherent selection bias may arise, since for example, studies may tend to be published more readily if they are statistically signiicant, or deemed to be morèinteresting' in terms of the impact of their outcomes. We develo...

BACKGROUND Institutes of the history of medicine, the theory of medicine, and medical ethics at German institutions of higher learning have created various e-learning options that are based on different learning platforms and tailored to the specific curricular needs of individual teaching. Up to now no valid data has been available about the types of such e-learning options as well as possibil...
