This paper presents a new self-clinching fastener to connect two sheets (or plates), made from similar or dissimilar materials, placed over one another by means of mechanical form-closed joint that is hidden inside the sheets. The development fastener, definition its main design variables and identification workability limits are carried out combined experimental numerical simulation work based...

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...

Groove is often described as a musical quality that can induce movement in a listener. This study examines the effects of listening to groove music on corticospinal excitability. Musicians and non-musicians listened to high-groove music, low-groove music, and spectrally matched noise, while receiving single-pulse transcranial magnetic stimulation (TMS) over the primary motor cortex either on-be...

electromagnetic forming is a high energy rate forming process. in this process, an electromagnetic lorentz body force is used for deformation of products. in this article, electromagnetic forming process was simulated for assembly of parts as an innovative method. in this research work, the effect of important parameters of process such as discharge energy, radius and width of rectangular groov...

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...

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...
