Concept maps are effective interventions in providing students with a holistic understanding of a domain while also allowing understanding of relationships among parts and across the engineering curricula. Yet when the domain of application is large, concept maps become overburdened with too much information and complexity. A function of the individual learners’ cognitive load abilities, this p...

We summarize the results of the response of monolithic steel plates and steel-polyurea bilayer plates to impulsive blast loads produced in direct pressure-pulse experiments, focusing on the deformation and failure modes of the plates. In these experiments, an impulsive pressure pulse is applied to a steel plate through water or soft polyurethane that simulates shock loading with a peak pressure...

BACKGROUND Intravenous zanamivir is a neuraminidase inhibitor suitable for treatment of hospitalized patients with severe influenza. METHODS Patients were treated with intravenous zanamivir 600 mg twice daily, adjusted for renal impairment, for up to 10 days. Primary outcomes included adverse events (AEs), and clinical/laboratory parameters. Pharmacokinetics, viral load, and disease course we...

(Received The intense magnetic field generated by the 20 megaampere Z machine at Sandia National Laboratories is being used as a pressure source for material science studies. An application we have studied in great detail involves using the intense magnetic field to accelerate flyer plates (small metal disks) to very high velocities (> 20 km/s) for use in shock loading experiments. We have used...

Interest in vibration energy harvesting technologies has increased significantly in the last decade, primarily due to the possibility of realizing ultra-low power sensor and communication circuits. In such low-power applications, it is paramount to maximize the efficiency of the harvesting system. Here, we propose the use of a simple MEMS cantilever as a power regulating hysteretic switch that ...

The negative effect of permanent contamination of populations because of spontaneous mutations does not appear to be very high if judged from the relatively good health of humans or many wild and domesticated species. This is partly explained by the fact that, in diploids, the new mutations are usually located in heterozygous loci and therefore are masked by wild-type alleles. The expression of...

Many parameters affect the behavior of tall buildings under seismic loads, some which are main shock-after shock records and using lateral load resistance systems in reinforced concrete buildings. End shear walls a kind walls, connecting their end This study was conducted on two 30-story structures, were subjected to sequences far fault analyzed by nonlinear time history analysis. The results i...
