RELATIONSHIP BETWEEN COMPACTING PRESSURE AND CONDITIONS IN PRESSING CHAMBER DURING BIOMASS PRESSING

Re-strengthening in AA6063 Alloy During Equal Channel Angular Pressing

Equal channel angular pressing (ECAP) is carried out using two different configurations for the exit channel of the ECAP die, i.e., relieved and choked, with angles of 0.2 °. It is found that using a die with relieved exit channel, the sample was extruded for 6 passes with no surface cracks and an average cell size of 727 nm and a fraction of high angle grain boundaries of 54 % were achieved. M...

Pressing 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...

Equi-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...

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...
