Appearance of Saturn's F ring azimuthal channels for the anti-alignment configuration between the ring and Prometheus

In this article we explore the aspect of the F ring with respect to the anti-alignment configuration between the ring and Prometheus. We focus our attention on the shape of the F ring's azimuthal channels which were first reported by Porco et al. (2005) and numerically explored by Murray et al. (2005), who found excellent agreement between Cassini's ISS reprojected images and their numerical model via a direct comparison. We find that for anti-alignment the channels are wider and go deeper inside the ring material. From our numerical model we find a new feature, an island in the middle of the channel. This island is made up of the particles that have been perturbed the most by Prometheus and only appears when this satellite is close to apoapsis. In addition, plots of the anti-alignment configuration for different orbital stages of Prometheus are obtained and discussed here.Comment: Number of pages: 12, number of tables: 1, number of figures:

Overview of Deeply Virtual Compton Scattering at HERMES

Deeply Virtual Compton Scattering represents the best experimental channel through which to understand Generalised Parton Distributions. The HERMES experiment measured the most diverse set of DVCS results of any experiment; this talk discusses the most recent sets of DVCS results released by HERMES and the unique experimental conditions found at HERMES that facilitated the measurements. We also examine the various ways in which the HERMES experimental measurements are being used to constrain GPDs and how future experiments can learn from the HERMES program.Comment: 4 pages, 2 figures, prepared for DIS201

Investigation of New Hampshire hydropower potential

The popularity of green and renewable energy has risen sharply in recent years, and hydropower has consistently been the most common form of renewable energy in both the US and the state of New Hampshire. As a result of this strong green movement, government organizations have seen increased pressure to produce figures to the public detailing the amount of hydropower potentially available in the country. Often these figures will depict very attractive numbers for the untapped hydropower potential in the country, yet the data do not seem realistic to anyone familiar with hydropower generation. This paper will attempt to de-rate these general estimates made for hydropower potential by government organizations, specifically in New Hampshire. It will be determined if these parties are ignoring basic hydropower design challenges in their estimations, such as system efficiency, generator capacity factors, and the economic feasibility of the projects themselves. These results should reveal the inaccuracies (if any) of the estimates by the government groups. To analyze the general feasibility of hydropower projects in New Hampshire, three case studies in hydropower system design will be examined

Book review: nuclear energy: what everyone needs to know

Reviewing nuclear energy and disentangling myth from reality is essential to informing public opinion and policy making, and this accessible text provides a useful basis for assessing the risks, costs and benefits, finds Murray Collins

Writing Center as Contact Zone: Resources for Mediation

When ESL writers write, they are attempting to be heard in an academic community. One of the academy’s shortcomings is its disinclination to hear from writers who struggle with academic discourse. In a contact zone, such as a university that includes accomplished and novice academics, communication becomes a casualty (particularly with novices whose first language is not English). If writing centers and their staffs are the cultural mediators of this contact zone, then we must first be afforded the tools to do our work: a good text, skilled teachers, sufficient funding, and an un-marginalized place on the campus. Irrespective of these resources, however, writing consultants can provide ESL writers with knowledge of contrastive rhetorics and how a failure to acculturate to demands for standard American academic writing may limit their success at the university level.University Writing Cente
