Hubble Space Telescope meteoroid-debris protection analysis

A system level failure could occur if the Hubble Space Telescope's (ST) capability to operate as a facility on-orbit is critically reduced or when a significant reduction in the quality of science data is registered. Failure could occur if a meteoroid/debris impact damages a component of a major support subsystem or if a meteoroid/debris penetration causes straylight contamination in the light shield, forward shell, aft shroud, or through the aperture door. The ST was analyzed to find the probability of no critical penetration. This probability value was found to be 92.25% for a two-year service life. A straylight leakage repair technique was recommended for the aft shroud, the region found most likely to be critically penetrated. Fozar tape and multilayer insulation blankets are suggested as posible repair materials

Leadership and capability development and deployment in the New Zealand State Service

This article describes the design during 2013 of a model and implementation principles of a leadership and capability development and deployment (LCDD) model for the state services system. In this process, an initial prototype model was developed to describe a desired future state. It was informed by the best traditions of state services leadership development, together with models used by the world’s best companies, such as Procter & Gamble, for leadership development (Filipkowski and Donlon, 2013). The model was then enhanced based on our research in other jurisdictions, including Australia, Singapore and the United Kingdom, and co-creation with stakeholders. This is further discussed in the article. Dr Mike Pratt is Professor of Leadership and Sustainability at the University of Waikato, and a professional director and business adviser. Dr Murray Horn is a former Secretary to the Treasury of New Zealand and bank chief executive, and a professional director and business adviser

Clearwing Moths Captured by Ultraviolet Light Traps in Southern Ohio (Lepidoptera: Sesiidae)

Trapping with ultraviolet light in mixed-oak forests of Lawrence and Vinton Counties, Ohio in 1995 and 1996 yielded 46 Synanthedon acerni and four Synanthedon arkansasensis, a clearwing moth record new for the state

Pitch Mass Borer, a New Clearwing Moth Record for Ohio (Lepidoptera: Sesiidae)

We report the Pitch Mass Borer clearwing moth, Synanthedon pini, from Vinton Furnace Experimental Forest, Dundas, Vinton County, Ohio, the first record for this state. A mature larva and two pupae were excised from resin masses of Scrub Pine, Pinus virginiana, a new host record, in early May 1999
