Molecular Gas and Star Formation in the Host Galaxy of I Zw 1

A recent analysis of high angular resolution NIR imaging and spectroscopic data in conjunction with Plateau de Bure interferometric mm-line observations indicate the presence of a circum-nuclear starburst ring of about 1.5 arcsec (1.5 kpc) diameter in I Zw 1. High angular resolution NIR imaging, using the MPE SHARP camera at the ESO NTT, HST V-band images, as well as NIR spectroscopy with MPE 3D provide an improved analysis of the star formation activity in the disk and nucleus of I Zw 1. We present first results from subarcsecond interferometric imaging in the 12CO(2-1) line using the Plateau de Bure Interferometer.Comment: Contributed talk presented at the Joint MPE,AIP,ESO workshop on NLS1s, Bad Honnef, Dec. 1999, to appear in New Astronomy Reviews; also available at http://wave.xray.mpe.mpg.de/conferences/nls1-worksho

Opportunities and challenges facing NGOs using sport as a vehicle for development in post-apartheid South Africa

Post-apartheid South Africa manifests poor social indicators with over half the population living below the poverty line and the worst levels of inequality in the world, with much work needed to overcome the skewed legacy of apartheid. Sport suffered in this system resulting in unequal access to sporting facilities and opportunities, meaning many South Africans cannot exercise their right to play. Despite this legacy, sport can fulfil a vital developmental role in alleviating some of these issues. The state has a major role to play but it must be supported by civil society and nongovernmental organisations (NGOs) who have the ability to deliver in situations where government has struggled. This article researches the opportunities and challenges NGOs encounter when using sport for development within the education system, in post-apartheid South Africa. This study used a qualitative approach to collect data on the opportunities and challenges encountered by two NGOs based in Cape Town that use sport as a means of development, but in markedly different ways. The study suggests that NGOs face a variety of conceptual, technical, logistical and organisational challenges using sport in schools and should enact certain measures to reduce resistance from educators and ensure successful programmes. The interaction between NGOs, schools and the state Department of Education is a complicated process that presents obstacles and opportunities. Nevertheless, despite these challenges it is clear NGOs can support schools in South Africa to optimise their physical activity programmes in the backdrop of a stagnating education system and a lack of sporting support from the government. NGOs in an educational setting such as schools operate in what Houlihan has identified as a crowded policy space. Yet, the observations in this study suggest that, particularly in the context of education, a partnership policy model of NGO work is preferred

Phobia and Phobic Relationships: A Visual Exploration

Phobia and Phobic Relationships: A Visual Exploration is an in-depth study through visual media of the fears that exist in everyday life. My own personal view of how phobia takes form is explored through self-portraits filled with dynamic color, composition, value, texture and shape. Composition enforces each particular phobia and interprets it as honestly as possible. All of the works are open for interpretation by the viewer. This written thesis and the artwork encourages the viewer to participate as a helping hand to benefit through care-taking a mentally ill person or in self-care. My own work is rewarded by the fact that I know I have been honest and have used a public exhibition to promote hope for the mentally diseased

Patterns of sedentary behaviour and physical activity in people following curative intent treatment for non-small cell lung cancer

This study aimed to compare patterns of sedentary behaviour (SB) and physical activity (PA) in people following curative intent treatment for non-small cell lung cancer (NSCLC) with healthy controls. Participants 6-10 weeks following lobectomy for NSCLC and healthy controls wore two activity monitors for 7 days. Waking hours were divided into time spent in SB (<1.5 metabolic equivalent of tasks (METs)), light intensity PA (LIPA ≥ 1.5 to <3.0METs) and moderate-to-vigorous intensity PA (≥3.0METs). Daily steps were also recorded. Data were available in 20 participants with NSCLC (13 females; 68 ± 10 years) and 20 healthy controls (13 females; 69 ± 5 years). The NSCLC group accumulated a greater percentage of time in SB in uninterrupted bouts ≥30 minutes (49% vs. 42%; p = 0.048). Further, the NSCLC group spent a lower percentage of waking hours in LIPA (21 ± 9% vs. 26 ± 8%; p = 0.04) and accumulated a lower percentage of time in this domain in uninterrupted bouts ≥10 minutes (13% vs. 19%; p = 0.025). The NSCLC group also had a lower daily step count (8863 ± 3737 vs. 11,856 ± 3024 steps/day; p = 0.009). Time spent in moderate-to-vigorous intensity PA was similar in both groups (p = 0.92). People following curative intent treatment for NSCLC spend more time in prolonged bouts of SB at the expense of LIPA

A 96-Channel FPGA-based Time-to-Digital Converter

We describe an FPGA-based, 96-channel, time-to-digital converter (TDC) intended for use with the Central Outer Tracker (COT) in the CDF Experiment at the Fermilab Tevatron. The COT system is digitized and read out by 315 TDC cards, each serving 96 wires of the chamber. The TDC is physically configured as a 9U VME card. The functionality is almost entirely programmed in firmware in two Altera Stratix FPGA's. The special capabilities of this device are the availability of 840 MHz LVDS inputs, multiple phase-locked clock modules, and abundant memory. The TDC system operates with an input resolution of 1.2 ns. Each input can accept up to 7 hits per collision. The time-to-digital conversion is done by first sampling each of the 96 inputs in 1.2-ns bins and filling a circular memory; the memory addresses of logical transitions (edges) in the input data are then translated into the time of arrival and width of the COT pulses. Memory pipelines with a depth of 5.5 $\mu$s allow deadtime-less operation in the first-level trigger. The TDC VME interface allows a 64-bit Chain Block Transfer of multiple boards in a crate with transfer-rates up to 47 Mbytes/sec. The TDC also contains a separately-programmed data path that produces prompt trigger data every Tevatron crossing. The full TDC design and multi-card test results are described. The physical simplicity ensures low-maintenance; the functionality being in firmware allows reprogramming for other applications.Comment: 32 pages, 13 figure

Long-distance staple transport in western Mesoamerica: Insights through quantitative modeling

Conceptualizations of pre-Hispanic staple transport remain underdeveloped. Conventional wisdom has long maintained that while prestige goods could demand long-distance transport, staple transport was short distance. A quantitative model reveals the fallacy of that argument and establishes the possibility of long-distance, overland staple transport in Mesoamerica by using maize tribute transport between Zempoala and Tenochtitlan as an example. This conclusion has implications for understanding Mesoamerican interregional exchange, ecology, and society
