objective(s): three-dimensional structures such as nanofibrous scaffolds are being used in biomedical engineering as well as provide a site for cells to attach and proliferate leading to tissue formation. in the present study, poly(vinyl pyrrolidone) (pvp)/ poly(vinyl alcohol)(pva) hybrid nanofibrous scaffold was synthesized by electrospinning. materials and methods: the effect of adding nano h...

This report outlines findings from an 18-month project examining the value of mounted police in the UK. The research approach took a broad view of the concept of value in police work, including responding to and preventing crime and disorder as well as building public trust and confidence in the police, providing reassurance and visibility. The project also examines the costs associated with mo...

Wearable devices for remote medical systems require a reliable power supply to enable full operation during long-term processes. Piezoelectric generators are promising energy sources that use human body movements generate energy. The wearable device should be able easily deform with tiny skin deformations achieve continual generation from standard movements. However, conventional piezoelectric ...

Cross-linked poly(vinylpyrrolidone) (PVP) is a heterogeneous and polymeric support that has been widely used in the preparation of numerous reagents and catalysts because of its commercial availability, stability, reasonable high loading capacity, good physicochemical structure and facile functionalization. Beside various applications in industry such as stabilizer, sugar coating and film coati...
