Self-supported aluminum thin films produced by vacuum deposition process

Self-supported aluminum thin film is produced by vacuum depositing the film on a polyvinyl formal resin film and then removing the resin by radiant heating in the vacuum. The aluminum film can be used as soon as the resin is eliminated

The eta ' signal from partially quenched Wilson fermions

We present new results from our ongoing study of flavor singlet pseudoscalar mesons in QCD. Our approach is based on (a) performing truncated eigenmode expansions for the hairpin diagram and (b) incorporating the ground state contribution for the connected meson propagator. First, we explain how the computations can be substantially improved by even-odd preconditioning. We extend previous results on early mass plateauing in the eta' channel of two-flavor full QCD with degenerate sea and valence quarks to the partially quenched situation. We find that early mass plateau formation persists in the partially quenched situation.Comment: Lattice2002(spectrum), 3 pages, 5 figure

What Research Should be Done and Why? Four Competing Visions among Ecologists

Information we collect about our planet depends, in part, on the questions scientists ask regarding the natural world. Asking other questions might lead to different innovations and alternative understandings of policy problems and their potential solutions. With a seemingly infinite number of potential study subjects but limited resources with which to study them, why have we chosen to focus on the topics that we have? Here, I present a Q-method study that explores ecologists\u27 thought processes as they evaluate the merits of potential research topics. The participants, ecologists attending the Ecological Society of America\u27s 2008 Annual Meeting, nominally agreed with one another that their discipline should contribute to solving environmental problems, but they interpreted that goal differently. This study uncovers four competing visions that ecologists have for their discipline. On the basis of these findings, I contend that ecology might be more effective in informing policy if priority setting were a more deliberative process and open to insights from individuals and institutions outside of ecology

Review of: Escape from the Ivory Tower: A Guide to Making Your Science Matter , by Nancy Baron

Collectively, ecologists produce a staggering amount of information each year. Using the Web of Science Journal Citation Reports subject classification to define the field of ecology, our discipline comprises 129 ecology-specific journals that in 2009 published an astounding 14 280 articles. How much of that information is being used by policymakers? How much is potentially useful to those audiences? The message in Nancy Baron’s new book, Escape from the ivory tower: a guide to making your science matter, is that all of it could be taken up by the media, publicized, and utilized by policymakers if only we could communicate it better to reporters and politicians. But communicating science and making it matter to the public or to policymakers are not the same thing, and the book falls short in addressing this latter point

Existence theorems in the geometrically non-linear 6-parametric theory of elastic plates

In this paper we show the existence of global minimizers for the geometrically exact, non-linear equations of elastic plates, in the framework of the general 6-parametric shell theory. A characteristic feature of this model for shells is the appearance of two independent kinematic fields: the translation vector field and the rotation tensor field (representing in total 6 independent scalar kinematic variables). For isotropic plates, we prove the existence theorem by applying the direct methods of the calculus of variations. Then, we generalize our existence result to the case of anisotropic plates. We also present a detailed comparison with a previously established Cosserat plate model.Comment: 19 pages, 1 figur
