Grain boundaries take leading role in deformation

Deformation of grain boundaries in polar ice

– The ice microstructure (grain boundaries) is a key feature used to study ice evolution and to investigate past climatic changes. We studied a deep ice core, in Dome Concordia, Antarctica, which records past mechanical deformations. We measured a “texture tensor” which characterizes the pattern geometry and reveals local heterogeneities of deformation along the core. These results question key...

complex patients; pharmacists take the leading role in community

in daily life, complexity results from countless factors. culture, environment, social and economic status and physical ability all contribute, and all complicate managing ill health. pharmacists bear witness to many of these complexities and increasingly must care for what have come to be known as ‘complex patients’.  the issue of  ‘complex patients’ is one that has been addressed by healthcar...

In daily life, complexity results from countless factors. Culture, environment, social and economic status and physical ability all contribute, and all complicate managing ill health. Pharmacists bear witness to many of these complexities and increasingly must care for what have come to be known as 'complex patients'.

Role of grain boundaries in magma migration and storage

We employ a continuous theory of two-phase flow to investigate the influence of grain boundary tension on distribution and migration of melts through a viscous matrix. The ‘disaggregation melt fraction’, the volume fraction of partial melt at which grain boundaries are completely wetted, is crucial in determining the total interfacial force per unit volume. In partially molten aggregates with s...
