Poetry within trauma-informed literacies has been influential to understanding youth writing. As the tendency focus on individual rather than structures of power remains, authors this essay point collective resistance and connect writing other creative texts in their engagement black life, livingness, pedagogical possibilities. Specifically, they draw feminist theories methodologies consider ra...

Why do we age? Since ageing is a near-universal feature of complex organisms, a convincing theory must provide a robust evolutionary explanation for its ubiquity. This theory should be compatible with the physiological evidence that ageing is largely due to deterioration, which is, in principle, reversible through repair. Moreover, this theory should also explain why natural selection has favou...

Optical microscopy has been contributing to the development of life science for more than three centuries. However, due to strong optical scattering in tissue, its in vivo imaging ability has been restricted to studies at superficial depths. Advances in photoacoustic tomography (PAT) now allow multiscale imaging at depths from sub-millimeter to several centimeters, with spatial resolutions from...

Tourism research is a relatively new, under-explored and under-researched discipline in sub-Saharan Africa in general but most especially in the Central African sub-region in particular in spite of its recognised potential for sustainable nature/eco tourism development. This is partly because the industry lacks the necessary patronage enjoyed by other economic sectors. As a result most governme...

The problem of accurate determination of the position, orientation and width of involute spur gear teeth using a single front-lit image is addressed. The information is used to compute global measures of tooth concentricity and pitch variations across a gear wheel. The approach is based on the use of specialised filters which make maximum use of the grey level information available in the image...

A comprehensive study on the structural, electronic and nonlinear optical (NLO) properties of alumina nanostructures (Al2O3)n with n = 2-5 belonging to the groups III and VI dopants carried out by density functional theory. The NBO charges exhibit dopant atoms caused to the increasing charge transfer and introduces acceptor-donor model for NLO response of alumin...
