Extreme runup from the 17 July 2006 Java tsunami

Abstract: [1] The 17 July 2006 magnitude Mw 7.8 earthquake off the south coast of western Java, Indonesia, generated a tsunami that effected over 300 km of coastline and killed more than 600 people, with locally focused runup heights exceeding 20 m. This slow earthquake was hardly felt on Java, and wind waves breaking masked any preceding withdrawal of the water from the shoreline, making this tsunami difficult to detect before impact. An International Tsunami Survey Team was deployed within one week and the investigation covered more than 600 km of coastline. Measured tsunami heights and run-up distributions were uniform at 5 to 7 m along 200 km of coast; however there was a pronounced peak on the south coast of Nusa Kambangan, where the tsunami impact carved a sharp trimline in a forest at elevations up to 21 m and 1 km inland. Local flow depth exceeded 8 m along the elevated coastal plain between the beach and the hill slope. We infer that the focused tsunami and runup heights on the island suggest a possible local submarine slump or mass movement.

A flexible bio-inspired H2-production photocatalyst

Abstract: Photocatalytic hydrogen generation from water splitting offers a viable potential solution for utilizing solar energy. Here we report a feasible synthesis of flexible bio-inspired Zn 0.5 Cd 0.5 S@PAN (polyacrylonitrile) mat-shaped photocatalyst with leaf-like structure, which shows high photocatalytic H 2 -production activity with a rate of 475 μmol h −1 per 50 mg of the photocatalyst and an apparent quantum efficiency of 27.4% at 420 nm. The hierarchically porous structure of the mat-shaped Zn 0.5 Cd 0.5 S@PAN greatly enhances the molecular diffusion/transfer kinetics, and enlarges the utilization efficiency of light through the multiple reflections and scattering effect. Moreover, a good dispersion of Zn 0.5 Cd 0.5 S nanoparticles (NPs) on the surface of PAN nanofibers prevents their aggregation. These features account for high H 2 -production activity of Zn 0.5 Cd 0.5 S@PAN. Remarkably, the integrity and flexibility of Zn 0.5 Cd 0.5 S@PAN mat-shaped photocatalyst facilitate their separation and re-use after photocatalytic reaction. Hierarchically porous leaf-like mat-shaped photocatalysts with high photocatalytic activity and stability should also find potential applications in solar cells, catalysis, separation and purification processes.

Best Practices in Clinical Supervision: Evolution of a Counseling Specialty

Abstract: A number of developments have marked the evolution of clinical supervision as a separate specialty since publication of the Standards for Counseling Supervisors in 1990, including accreditation and counselor licensure standards, supervisor credentials, and research on supervision practice and supervisor training, nationally and internationally. Such developments culminated in the development of a statement of Supervision Best Practices Guidelines. The Guidelines are described, followed by suggestions for their implementation and further evolution through research.
