Cracking in Silicon solar cells is an important factor for the electrical power-loss of photovoltaic modules. Simple geometrical criteria identifying the amount of inactive cell areas depending on the position of cracks with respect to the main electric conductors have been proposed in the literature to predict worst case scenarios. Here we present an experimental study based on the electrolumi...

In 2004, a team comprised of researchers and service providers launched the Safer Crack Use, Outreach, Research and Education (SCORE) project in the Downtown Eastside of Vancouver, British Columbia, Canada. The project was aimed at developing a better understanding of the harms associated with crack cocaine smoking and determining the feasibility of introducing specific harm reduction strategie...

The paper presents a new healing system that uses pre-tensioned hybrid tendons to close cracks in cementitious structural elements. comprise an inner core, formed from aramid fibre ropes, and outer sleeve made shape memory PET. During the manufacturing process, core of tendon is put into tension compression, such equilibrium. A set are then cast element heat activated once cracking occurs. This...

The crack growth behaviour of the alloy CM 247 LC is investigated for out-of-phase TMF and isothermal tests at same temperature as minimum in tests. results suggest that it possible to characterise if experimental corrections closure are accounted for. replication these using a numerical FE-solver similar behaviour, suggesting main mechanism place plasticity-induced closure. A pragmatic analyti...
