Program document for Energy Systems Optimization Program 2 (ESOP2). Volume 1: Engineering manual

The Energy Systems Optimization Program, which is used to provide analyses of Modular Integrated Utility Systems (MIUS), is discussed. Modifications to the input format to allow modular inputs in specified blocks of data are described. An optimization feature which enables the program to search automatically for the minimum value of one parameter while varying the value of other parameters is reported. New program option flags for prime mover analyses and solar energy for space heating and domestic hot water are also covered

Pressure Gradients Driving Ion Transport in the Topside Martian Atmosphere

An edited version of this paper was published by AGU. Copyright 2019 American Geophysical Union.Magnetic and thermal pressure gradient forces drive plasma flow in the topside ionosphere of Mars. Some of this flow can contribute to ion loss from the planet and thus affect atmospheric evolution. MAVEN measurements of the magnetic field, electron density, and electron temperature, taken over a 3‐year time period, are used to obtain averaged magnetic and thermal pressures in the topside ionosphere versus altitude, solar zenith angle, and latitude. Magnetic pressures are several times greater than thermal pressures for altitudes greater than about 300 km; that is, the plasma beta is less than one. The total pressure increases with altitude in the ionosphere and decreases with increasing solar zenith angle. Using these pressure patterns in the dayside ionosphere to estimate the pressure gradient force in the fluid momentum equation, we estimate horizontal day‐to‐night plasma flow speeds of a few kilometers per second near 400 km

Footballers' Image Rights in the New Media Age

Image rights, broadly defined as the commercial appropriation of someone's personality, including indices of their image, voice, name and signature, have become increasingly important in the political economy of media sport. A range of legal, economic and political arguments have developed in the UK as to what image rights actually are, their legal efficacy and their potential impact on developments in the long-standing relationship between sport and the media. This paper focuses on the problematic definition of the term in the UK context and how it relates to certain economic and commercial transformations in British football. Using the English Premier League and the ‘celebrity footballer’ David Beckham as its primary focus, the paper traces the rise of image rights clauses in player contracts. This process is analysed in the context of rapid and dramatic change in the media coverage of the sport. The paper focuses on the growing legal complexities of protecting star images in relation to the Internet and the wider issues of football, fandom and popular culture

Identification, characterization and evolution of a primate β-defensin gene cluster

Defensins are members of a large diverse family of cationic antimicrobial peptides that share a signature pattern consisting of six conserved cysteine residues. Defensins have a wide variety of functions and their disruption has been implicated in various human diseases. Here we report the characterization of DEFB119–DEFB123, five genes in the human β-defensin cluster locus on chromosome 20q11.1. The genomic structures of DEFB121 and DEFB122 were determined in silico. Sequences of the five macaque orthologs were obtained and expression patterns of the genes were analyzed in humans and macaque by semiquantitative reverse transcription polymerase chain reaction. Expression was restricted to the male reproductive tract. The genes in this cluster are differentially regulated by androgens. Evolutionary analyses suggest that this cluster originated by a series of duplication events and by positive selection. The evolutionary forces driving the proliferation and diversification of these defensins may be related to reproductive specialization and/or the host–parasite coevolutionary process

Passion in the Workplace: Empirical Insights from Team Sport Organisations

Although sport management scholars have focused on a fairly wide number of psychologically-related constructs in the workplace, passion has not been part of this research agenda. The present study is the first attempt to fill this gap by exploring employees’ passion in the workplace setting of sport organisations. It does so by applying for the first time the dualistic model of passion developed by Vallerand et al. (2003), which measures two distinct types of passion: harmonious and obsessive. Online survey data were gathered from administrative employees in the United Kingdom’s football industry, responsible for either business-related functions or the clubs’ social agenda (N=236) in order to measure the passion experienced by individuals guided by different institutional logics. The particular instrument has two components: harmonious and obsessive passion towards the job. Besides the passion scales, the survey contained measures related to demographic variables (e.g., age, gender and education), to employment position in the organisation and to previous job experience. Data were statistically analysed in Confirmatory Factor Analysis (CFA) and analysis of variance, using SPSS and Amos 18.0. To determine the effect of contextual variables on the passion for the job, t-test and ANOVA were also used. Both groups of employees are passionate about their job. They remain harmoniously passionate throughout their career and show low level of obsessive passion. The type of work activities influences both levels of harmonious and obsessive passion experienced by personnel within sport organisations with employees responsible for the social agenda being slightly more harmoniously and obsessively passionate compared to those responsible for the business agenda. Vallerand et al.’s (2003) dualistic model of passion has been adapted to measure passion at workplace within sport organisations. The particular working environment that forms these organisations attracts and/or facilitates employees to experience a positive work–life balance

'Surf's up!':A call to take english soccer fan interactions on the internet more seriously

Soccer fandom practices in England have been significantly impacted by globalization. The creation of the Premier League in 1992, and the way in which satellite television company BSkyB dominated coverage of this, together with other developments, have led to changes in how fans consume top-level English soccer. Whilst such global transformations are well documented in the sociology of soccer literature, the implications of the rise of the most advanced global form of communication - the Internet - on the practices of fans of English soccer clubs, have not been fully taken into account by academics. As such, the significance of the Internet as a site for fans to interact remains under-investigated. This article argues that online interactions between fans of English clubs need to be taken more seriously by academics if they are to more fully understand how soccer contributes to the maintenance of social identities in contemporary England

Determinants of recovery from post-COVID-19 dyspnoea: analysis of UK prospective cohorts of hospitalised COVID-19 patients and community-based controls

Background The risk factors for recovery from COVID-19 dyspnoea are poorly understood. We investigated determinants of recovery from dyspnoea in adults with COVID-19 and compared these to determinants of recovery from non-COVID-19 dyspnoea. Methods We used data from two prospective cohort studies: PHOSP-COVID (patients hospitalised between March 2020 and April 2021 with COVID-19) and COVIDENCE UK (community cohort studied over the same time period). PHOSP-COVID data were collected during hospitalisation and at 5-month and 1-year follow-up visits. COVIDENCE UK data were obtained through baseline and monthly online questionnaires. Dyspnoea was measured in both cohorts with the Medical Research Council Dyspnoea Scale. We used multivariable logistic regression to identify determinants associated with a reduction in dyspnoea between 5-month and 1-year follow-up. Findings We included 990 PHOSP-COVID and 3309 COVIDENCE UK participants. We observed higher odds of improvement between 5-month and 1-year follow-up among PHOSP-COVID participants who were younger (odds ratio 1.02 per year, 95% CI 1.01–1.03), male (1.54, 1.16–2.04), neither obese nor severely obese (1.82, 1.06–3.13 and 4.19, 2.14–8.19, respectively), had no pre-existing anxiety or depression (1.56, 1.09–2.22) or cardiovascular disease (1.33, 1.00–1.79), and shorter hospital admission (1.01 per day, 1.00–1.02). Similar associations were found in those recovering from non-COVID-19 dyspnoea, excluding age (and length of hospital admission). Interpretation Factors associated with dyspnoea recovery at 1-year post-discharge among patients hospitalised with COVID-19 were similar to those among community controls without COVID-19.
