The SNAP Strong Lens Survey

Basic considerations of lens detection and identification indicate that a wide field survey of the types planned for weak lensing and Type Ia SNe with SNAP are close to optimal for the optical detection of strong lenses. Such a ``piggy-back'' survey might be expected even pessimistically to provide a catalogue of a few thousand new strong lenses, with the numbers dominated by systems of faint blue galaxies lensed by foreground ellipticals. After sketching out our strategy for detecting and measuring these galaxy lenses using the SNAP images, we discuss some of the scientific applications of such a large sample of gravitational lenses: in particular we comment on the partition of information between lens structure, the source population properties and cosmology. Understanding this partitioning is key to assessing strong lens cosmography's value as a cosmological probe.Comment: 6 pages, 4 figures.

Differentiation Of Murine Erythroleukemic Cells During Exposure To Microwave Radiation

Cultures of murine erythroleukemic cells undergoing erythroid differentiation in response to induction by hexamethylene bisacetamide (HMBA) were exposed to 1180-MHz microwave (MW) radiation for 48 h while maintained at 37.4°C by variable-temperature air flow. Exposures at 1180 MHz were at 5.5, 11, and 22 mW/cm2 with a normalized specific absorption rate of 3.32 W/kg per mW/cm2. HMBA-induced control cells were incubated in a 37.4°C water bath. Mean cell doubling time was 16.5 h in both the irradiated cultures and the control cultures. About 65% of the cells of irradiated cultures and control cultures were benzidine-positive differentiated cells. Both the irradiated cultures and the control cultures contained approximately 58 μg of hemoglobin/mg total cytoplasmic protein. The absence of any change in these parameters suggests that MW radiation at 1180 MHz and similar frequencies exerts no effect on proliferation and differentiation of mammalian cells in the absence of hyperthermia

An Empirical Study of the Adoption and Diffusion of Electronic Commerce in the Car Industry in Western Australia

This paper reports on qualitative case study research into the effects and impacts, and hence the adoption and diffusion of e-commerce in the car industry in Western Australia. To date, care dealers are typically not particularly internet savvy, and thus the advent of internet-based business is offering opportunities to them, but is also causing some anxiety. Aggregators who, by pooling dealer content onto one web site, offer a relatively simple, relatively low cost way of getting onto the internet are helping many of the car dealers to develop an active presence on the web. But generally speaking, internal business processes are not being changed to accommodate the new way of doing business, and there is great uncertainty as to how significant the impact of the internet will be on their business into the future. Few dealers were willing not to be involved on the internet because of their fear of being left behind. However, at present, relatively few are seeing an appreciable impact on their business because of their web presence
