The development of the multiproperty apparatus to include high temperature determinations of specific heat, enthalpy and thermal diffusivity in addition to the properties already measured is described. The latter properties include thermal conductivity, electrical resistivity, Lorenz ratio, total hemispherical emittance, spectral emittance at 0.65 microns and Thomson coefficient. The specific h...

The new interface of the Web of Science (of Thomson Reuters) enables users to retrieve sets larger than 100,000 documents in a single search. This makes it possible to compare publication trends for China, the USA, EU-27, and smaller countries, with the data in the Scopus database of Elsevier. China no longer grew exponentially during the 2000s, but linearly. Contrary to previous predictions on...

We have studied diffusion controlled growth of an isolated, misfitting precipitate in a supersaturated matrix using a phase field model. Treating our simulations as computer experiments, we have critically compared our simulation results with those from Zener-Frank and Laraia-Johnson theories for the growth of non-misfitting and misfitting precipitates, respectively. The agreement between simul...

In this paper, we compare a variety of properties of liquid nickel calculated with two different embedded atom model functions @J. Cai and Y. Y. Ye, Phys. Rev. B 54, 8398 ~1996!; M. I. Baskes, J. I. Angelo, and N. R. Moody, in Hydrogen Effects on Material Behavior, edited by N. R. Moody and A. W. Thomson ~The Minerals, Metals, and Materials Society, Warrendale, PA, 1995!# and four variations of...

Based on recently collected Pteromalidae (Hymenoptera: Chalcidoidea), 13 species were identified from genera of Pteromalinae that are characterized in part by the female clava being distinctly acuminate or apically bearing a narrow spicula. Included are two species of Callitula Spinola, three species of Homoporus Thomson, seven species of Norbanus Walker, and one species of Rhaphitelus Walker. ...

A new 10 channel Thomson scattering (TS) system was installed on the ASDEX Upgrade tokamak to measure radial profiles of electron density and temperature at the plasma edge with high radial resolution. Together with the already existing TS system, which is now used for the core plasma, electron density and temperature profiles extending from the edge to the core are now obtained in a single dis...

Helicases are specialized molecular motors that separate duplex nucleic acids into single strands. The RecQ family of helicases functions at the interface of DNA replication, recombination and repair in bacterial and eukaryotic cells. They are key, multifunctional enzymes that have been linked to three human diseases: Bloom's, Werner's and Rothmund-Thomson's syndromes. This review summarizes re...

A taxonomic revision based on the study of the external morphology and the terminalia of Phygopoda Thomson, 1864 and Pseudophygopoda Tavakilian & Peñaherrera-Leiva, 2007 is presented. The genera and their species are redescribed. Five synonymies are proposed: Panamapoda Clarke, 2014 and Paraphygopoda Clarke, 2014 = Pseudophygopoda Tavakilian & Peñaherrera-Leiva, 2007; Paraphygopoda viridimicans...

As we approach a new period of evaluation of Brazilian Graduate Programs by the Ministry of Education, it seems appropriate to revisit the rating systems for scientific journals. According to the Ulrich’s Periodicals Directory, there are about 300,000 scientific periodicals in the world today. However, 270,000 of these are not subject to the process of peer review, meaning that only 30,000 jour...

The classical Kelvin-Thomson (CKT) equation does not consider the interaction of condensing molecules with the ions and hence is not able to treat polar and nonpolar molecules differently. The ion-clustering enthalpy and entropy changes predicted by CKT equation for small ions are known to be significantly less negative than those observed. In this paper, we derive a modified Kelvin-Thomson (MK...
