Countdown For Energy Research, Development and Demonstration In America

The energy research business is rapidly developing an appreciation of time elements which indicate that in order for a system” to compete with the big five prime fuels for the generation of electric energy, 1982 is going to be a critical year whereby RD & D efforts must provide on-line results

Industrial Innovations and Management toward More Efficient Usage of Electrical Energy

This paper deals with some of the industrial accomplishments in alleviating energy supply and demand problems. A survey is presented on how electrical energy in America is generated, resources used and kilowatt usage for the years 1970 to and including 1974. Conservation of electrical energy is the main theme in which three primary areas of innovation and utilization of industrial equipment are discussed; induction, lighting, heating and air conditioning. An awareness of natural gas shortages and the trend toward an electric economy are reviewed. The real challenge to energy management is apparent in order to handle the greatest expansion in energy technology since the mid-1800\u27s

Children\u27s Attitudes Toward the Dental Experience

The purpose of this study was to examine the attitudes of children toward the dental visit. A group of children who had undergone dental treatment with the use of nitrous oxide-oxygen served as the experimental group while children who had received dental treatment without the use of nitrous oxide-oxygen served as the control group. Attitudes toward the dental experience among these two groups were compared to determine any differences or similarities due to the type of treatment used. Data were also collected on the parents of the children to determine whether the child\u27s attitude toward the dental visit tended to reflect the attitude toward dentistry as expressed by the accompanying parent. Forty- five children between the ages of four and ten years old were asked t o identify a hypothetical child depicted in three specific situations as being either Happy or Sad. The three situations were defined as follows : (1) A child coming from the ice cream shop, (2) A child who just cut a finger, and (3) A child just leaving the dentist\u27s office. The parents in this study were asked to rate their anxiety related to visiting the dentist as being either (1) very relaxed, (2) generally relaxed, (3) generally anxious, or (4) very anxious. No significant difference was established between the nitrous oxide-oxygen children and the nonnitrous oxide group in relation to their attitudes toward the dental experience. No significant relationship was noted between the child\u27s attitude and the respective parent\u27s attitude in relation to the dental visit. A significant relationship between the boys and the girls was noted in the Happy classification group when the sex of the child was compared to the child\u27s point of reference as given in the hypothetical dental situation

Estimating the extent of Antarctic summer sea ice during the Heroic Age of Antarctic Exploration

In stark contrast to the sharp decline in Arctic sea ice, there has been a steady increase in ice extent around Antarctica during the last three decades, especially in the Weddell and Ross seas. In general, climate models do not to capture this trend and a lack of information about sea ice coverage in the pre-satellite period limits our ability to quantify the sensitivity of sea ice to climate change and robustly validate climate models. However, evidence of the presence and nature of sea ice was often recorded during early Antarctic exploration, though these sources have not previously been explored or exploited until now. We have analysed observations of the summer sea ice edge from the ship logbooks of explorers such as Robert Falcon Scott, Ernest Shackleton and their contemporaries during the Heroic Age of Antarctic Exploration (1897–1917), and in this study we compare these to satellite observations from the period 1989–2014, offering insight into the ice conditions of this period, from direct observations, for the first time. This comparison shows that the summer sea ice edge was between 1.0 and 1.7° further north in the Weddell Sea during this period but that ice conditions were surprisingly comparable to the present day in other sectors

Working to Feel Better or Feeling Better to Work? Discourses of Wellbeing in Austerity Reality TV

By focusing on discourses within the ‘cultural economy’ of reality TV, the following considers the wider positioning of waged labor as essential for mental health during a period of austerity. The findings suggest that discourses of mental health and wellbeing construct figures of a ‘good’ welfare-recipient as one who achieves wellbeing through distancing themselves from the welfare state and progress toward waged work. Framed within the landscape of ‘psycho-politics’, wellbeing and unemployment are arguably entangled to legitimize current welfare policy, placing responsibility on individuals for economic and health security and dissolving concerns over austerity’s systemic impact

Predicting resilience of ecosystem functioning from co‐varying species' responses to environmental change

Understanding how environmental change affects ecosystem function delivery is of primary importance for fundamental and applied ecology. Current approaches focus on single environmental driver effects on communities, mediated by individual response traits. Data limitations present constraints in scaling up this approach to predict the impacts of multivariate environmental change on ecosystem functioning. We present a more holistic approach to determine ecosystem function resilience, using long‐term monitoring data to analyze the aggregate impact of multiple historic environmental drivers on species' population dynamics. By assessing covariation in population dynamics between pairs of species, we identify which species respond most synchronously to environmental change and allocate species into “response guilds.” We then use “production functions” combining trait data to estimate the relative roles of species to ecosystem functions. We quantify the correlation between response guilds and production functions, assessing the resilience of ecosystem functioning to environmental change, with asynchronous dynamics of species in the same functional guild expected to lead to more stable ecosystem functioning. Testing this method using data for butterflies collected over four decades in the United Kingdom, we find three ecosystem functions (resource provisioning, wildflower pollination, and aesthetic cultural value) appear relatively robust, with functionally important species dispersed across response guilds, suggesting more stable ecosystem functioning. Additionally, by relating genetic distances to response guilds we assess the heritability of responses to environmental change. Our results suggest it may be feasible to infer population responses of butterflies to environmental change based on phylogeny—a useful insight for conservation management of rare species with limited population monitoring data. Our approach holds promise for overcoming the impasse in predicting the responses of ecosystem functions to environmental change. Quantifying co‐varying species' responses to multivariate environmental change should enable us to significantly advance our predictions of ecosystem function resilience and enable proactive ecosystem management

UVM Tobacco Use and Attitudes After Implementation of a Tobacco-Free Policy

Introduction: Widespread public health initiatives have led to falling smoking rates. Currently, 1,620 U.S. colleges have adopted smoke-free policies. In August 2015, the University of Vermont (UVM) adopted a tobacco-free policy that bans all forms of tobacco use on university property. The purpose of this study was to compare tobacco use and attitudes before and after policy implementation.https://scholarworks.uvm.edu/comphp_gallery/1230/thumbnail.jp

Quantum dark solitons in Bose gas confined in a hard wall box

Schr\"odinger equation for Bose gas with repulsive contact interactions in one-dimensional space may be solved analytically with the help of the Bethe ansatz if we impose periodic boundary conditions. It was shown that in such a system there exist many-body eigenstates directly corresponding to dark soliton solutions of the mean-field equation. The system is still integrable if one switches from the periodic boundary conditions to an infinite square well potential. The corresponding eigenstates were constructed by M. Gaudin. We analyze weak interaction limit of Gaudin's solutions and identify parametrization of eigenstates strictly connected with single and multiple dark solitons. Numerical simulations of detection of particle's positions reveal dark solitons in the weak interaction regime and their quantum nature in the presence of strong interactions.Comment: 7 pages, 4 figures, version accepted for publication in Phys.
