Estimating Water Demand Schedules for Selected Industries in Arkansas

Water demand functions for the paper and chemical industries in the state of Arkansas were estimated utilizing data collected from individual plants throughout the state. Regression analysis was used to estimate demand functions from a data base which included information on intake and gross water use by source, recirculated water use, costs of acquiring, treating, and discharging water, plant output, employment, and level of technology. The demand for intake water was estimated as an exponential function of average water costs and the level of technology primarily. Price elasticities of demand were estimated as approximately equal to one for both industries. The results of this study could be used to determine the effects of various public policies on the withdrawal of water for industrial purposes

Poetry and the Post-Apocalyptic Paradox: North American Indigenous Disruptions to the Westernized Self

This three-chapter project explores the work of three poets, each identifying with different North American indigenous tribes. Their work challenges western poetic conventions and notions of individualism to offer alternative worldviews and complicate mainstream oversimplifications of American Indian identity. Brandi MacDougall investigates assumptions of the Western Self represented by the I Perspective common in Western thought; Sherman Alexie revises the sonnet form to portray the complexity of how contemporary American Indians navigate the blending of capitalist institutions and native traditions; Kristi Leora offers readers an enlightened conception of self-hood by balancing processes of western socialization with native cosmology. Ultimately, this project is a student’s dive into the shallow waters of a deep, perhaps infinite pool of understanding and existence that can never be fully learned, understood or experienced from his personal, subjective perspective

The star formation history of intermediate‐redshift late‐type galaxies

We combine the latest observations of disc galaxy photometry and rotation curves at moderate redshift from the FORS Deep Field (FDF) with simple models of chemical enrichment. Our method describes the build‐up of the stellar component through infall of gas and allows for gas and metal outflows. In this framework, we keep a minimum number of constraints and we search a large volume of parameter space, looking for the models that best reproduce the photometric observations in the observed redshift range (0.5 < z < 1). We find that star formation efficiency correlates well with vmax, so that massive discs are more efficient in the formation of stars and have a smaller spread in stellar ages. This trend presents a break at around vmax∼ 140 km s−1. Galaxies on either side of this threshold have significantly different age distributions. This break has been already suggested by several authors in connection with the contribution from either gravitational instabilities or supernova‐driven turbulence to star formation. The gas infall time‐scale and gas outflows also present a correlation with galaxy mass, so that massive discs have shorter infall time‐scales and smaller outflow fractions. The model presented in this paper suggests that massive discs have formation histories resembling those of early‐type galaxies, with highly efficient and short‐lived bursts, in contrast with low‐mass discs, which have a more extended star formation history. The ages correlate well with galaxy mass or luminosity, and the predicted gas‐phase metallicities are consistent with the observations of local and moderate‐redshift galaxies. One option to explain the observed shallow slope of the Tully-Fisher relation at intermediate redshift could be small episodes of star formation in low‐mass disc

Médecine et physiognomonie du xive au début du xvie siècle

La médecine et la physiognomonie étaient entrelacées depuis l'Antiquité. Cet entrelacement s'intensifia énormément à partir de 1300 environ. La physiognomonie savante adopta entièrement le concept de complexion et la théorie humorale comme fondement explicatif de tous les signes physiognomoniques. Le discours physiognomonique ressembla au discours médical et reposa fortement sur des autorités médicales. La pratique physiognomonique en vint à ressembler à un bilan médical. Les physiognomonistes se mirent à vanter l'observation physiognomonique pour les médecins désireux d'améliorer leur savoir-faire dans l'identification d'une complexion.Medecine and physiognomy (1300-1500). Medicine and physiognomy were intertwined since ancient times. This intertwinement dramatically intensified from c. 1300 onwards. Learned physiognomy fully adopted the concept of complexion and humoral theory as an explanatory basis for the physiognomic signs. Physiognomic learned discourse resembled medical discourse and heavily relied on medical authorities. Physiognomic practice came to resemble a medical check-up. Physiognomers came to boast the usefulness of the physiognomic gaze for physicians, who wished to improve their skill of identifying complexion
