A Pressing Need
As a database format, XML (GML by extension) can be queried. In order to do this, we need a query language (of general use) to retrieve information from an XML document. Nevertheless, it is necessary to enrich the query language over XML features with spatial operators if we wish to apply it over spatial data encoded with GML. Otherwise, these query languages could only be used to query alphanu...
متن کاملPressing mitochondrial genetics forward.
Mitochondria are crucial for many cellular functions. In this issue of Cell Reports, studies from Lanning et al. and Wolf and Mootha describe RNAi approaches to screening the mitochondrial proteome. Unexpectedly, they uncover key roles for two poorly characterized mitochondrial proteins: AK4 and FASTKD4. These studies provide examples of the power of forward genetic screens, even when screening...
متن کاملSensing a N D Modeling of the Hot Isostatic Pressing of Copper Pressing
-A detailed experimental evaluation of mathematical models for densification during hot isostatic pressing (HIP) has been conducted using high purity copper powder as a model system. Using a new eddy current sensor, the density of cylindrical compacts has been measured/n situ and compared with model predictions for the HIP process. Pressure shielding by the can has been found to influence the d...

متن کاملEqui-Channel Angular Pressing
Equal channel angular Pressing (ECAP) is an innovative technique for developing ultrafine-grained microstructures first developed by Segal et al in 1981 in the former Soviet Union. The ECAP method consists of two channels that intersect at an angle, generally comprised between 90◦ and 135◦ . The deformation is produced by shear as the billet is extruded through the channels. One of the geometri...
