In the present paper, we report a systematic investigation of planform geometry and excitation level effects on dynamics power generation characteristics polyvinylidene difluoride (PVDF)-based cantilevered vibration energy harvesters. Piezoelectric harvesters provide promising harvesting solution for widespread use wireless sensors in remote locations. Highly flexible PVDF polymers offer resona...

The autologous and allogeneic immunological humoral response of breast cancer patients to breast tumours was investigated by ELISA assay of both the serum and the supernatants of transformed lymphocytes from the patients and controls. No specificity or increased titre relative to the controls was observed in serum antibody. However, when the response was dissected by the use of clones of transf...

Dredged material dumping is one of the most important locally generated problems to be considered in harbors’ management. The present work was carried out assess physical and particle size characteristics seabed core sediments Damietta harbor basin offshore area, with main aim proposing a synergetic approach sediment In addition tosuggestinga new site that will solve problem redispersing dumped...

In a model for rotating non-Boussinesq convection with mean flow, we identify a regime of spatiotemporal chaos that is based on a hexagonal planform and is sustained by the induced nucleation of dislocations by penta-hepta defects. The probability distribution function for the number of defects deviates substantially from the usually observed Poisson-type distribution. It implies strong correla...

An Unmanned Aerial System (UAS) has been developed which is based on an aerodynamically functionalized planar wideband antenna. The antenna utilizes a planar circular dipole metallization scheme. The aerodynamic structure implements a planform similar to the Nutball flier, a hobbyist flight architecture. The resulting codesign achieved a large impedance bandwidth defined by a voltage standing w...

The sensitivity of a one-line longshore shoreline change model to the incident wave direction is evaluated at Narrabeen Beach (Australia). As previously observed, application using conditions generated along 10-m depth contour produces long-term reorientation coastline, with an initial transition period and then new stable equilibrium during 10-year from 2005 2015. However, this coastline in pl...
