Radar Scattering from Foamed Plastic Target Supports

This study investigates the scattering from foamed ranges to support all sizes of targets for radar cross section measurements. Two common foamed plastics, styrofoam and expanded bead polystyrene (EPS), are discussed. Two types of scattering are associated with foamed plastic, coherent and incoherent. The incoherent is normally the lowest, but has not been satisfactorily quantified. Coherent scattering is related to the shape of the target, and the emphasis of this study is on the coherent return. One goal was to predict the coherent RCS of an EPS column using the Uniform Theory of Diffraction (UTD). It was found that UTD can accurately predict the backscatter of an EPS column consisting of flat and curved surfaces. The second goal was to experimentally study the effects of shaping on coherent RCS. The benefits of adding a vertical slope to circular cylindrical columns was studied. RCS reductions of approximately 20 dB were achieved. Some low RCS column shapes were also measured; sloping did not produce a measurable RCS reduction in these cases

A STUDY OF THE DINAKA PIPE DANCE OF THE PEDI PEOPLE IN SOUTH AFRICA

This article provides a description and musical analysis of the Pedi genre known as dinaka, as it is currently practised (2016) in the rural areas throughout the Limpopo province. The role of this music is examined along with the implications of learning and performing it as a cultural outsider. The construction, methods of tuning, and playing techniques of the pipes, drums, and other instruments associated with dinaka are discussed. The form and structure of the music are interpreted as well as the idioms of rhythm, melody, and dance repertoire which imbue the genre with a distinct sound. Common methods for creating improvisational variations among the instrumental and dance parts are explained. The connection of dinaka to styles of Pedi vocal music is examined along with the proverbial meanings of the songs with which these melodies and rhythms are associated. Transcriptions of the dance steps, pipe melodies and drum rhythms have been developed to provide a visual representation of the music. The aim is to provide a resource from which one can study and understand the many aspects of dinaka

Environmental Water Rights Transfers in a Nonprofit Institutional Structure

Increased demand for diminishing water resources has created the need for creative water management strategies. One technique perused in the western United States is the purchase of water rights by non-profit organizations for environmental in-stream uses. This paper looks at the Columbia Basin as a case study of the motivations of non-profit organizations. It shows how the institutional structure reduces transaction costs associated with water rights transfers and how non-profit organizations can incentivize water conservation in the western United States

C^+ distribution around S1 in rho Ophiuchi

We analyze a [C II] 158 micron map obtained with the L2 GREAT receiver on SOFIA of the emission/reflection nebula illuminated by the early B star S1 in the rho-OphA cloud core. This data set has been complemented with maps of CO(3-2), 13CO(3-2) and C18O(3-2), observed as a part of the JCMT Gould Belt Survey, with archival HCO^+(4-3) JCMT data, as well as with [O I] 63 and 145 micron imaging with Herschel/PACS. The [C II] emission is completely dominated by the strong PDR emission from the nebula surrounding S1 expanding into the dense Oph A molecular cloud west and south of S1. The [C II] emission is significantly blue shifted relative to the CO spectra and also relative to the systemic velocity, particularly in the northwestern part of the nebula. The [C II] lines are broader towards the center of the S1 nebula and narrower towards the PDR shell. The [C II] lines are strongly self-absorbed over an extended region in the S1 PDR. Based on the strength of the [13C II] F = 2-1 hyperfine component, [C II] is significantly optically thick over most of the nebula. CO and 13CO(3-2) spectra are strongly self-absorbed, while C18O(3-2) is single peaked and centered in the middle of the self-absorption. We have used a simple two-layer LTE model to characterize the background and foreground cloud contributing to the [C II] emission. From this analysis we estimate the extinction due to the foreground cloud to be ~9.9 mag, which is slightly less than the reddening estimated towards S1. Since some of the hot gas in the PDR is not traced by low J CO emission, this result appears quite plausible. Using a plane parallel PDR model with the observed [OI(145)]/[C II] brightness ratio and an estimated FUV intensity of 3100-5000 G0 suggests that the density of the [C II] emitting gas is ~3-4x10^3 cm^-3.Comment: Accepted for publication in Astronomy & Astrophysic
