This study focuses on the environmental impacts of the electricity production scenarios proposed for France for 2060 by the French electricity network manager, RTE. They consider an increasing electricity consumption and a production without fossil fuels, essentially based on wind, photovoltaic, hydraulic, and, for some, nuclear power. The total power to install is significantly higher than the current one; it is higher in the scenarios that rely more on photovoltaic and less on nuclear. Renewable energies require [...]

This project demonstrates how to use existing syntheses of many decades of historical social science research to produce empirically derived land-use maps in a GIS for large regions for a specific target year at a resolution appropriate to the calibration of existing anthropogenic land-cover change (ALCC) models. Disagreement among the outputs of various ALCC models results from differing estimates of population and assumptions about how much food a given population requires and the productivity per unit area of va [...]

Humans are integrally connected to, yet in many ways disconnected from, nature. Across cultures, nature has been celebrated and revered in religion, traditions, rituals and community connectedness. While unfavorable conditions in nature can cause harm, closer contact with nature has been shown to reduce stress, strengthen immune systems, and improve mental health and physical wellbeing. This paper briefly describes outdoor therapies and a range of nature-based interventions assisting practitioners in serving their [...]

Biogas is a promising resource for the production of H2 since it liberates energy by recycling waste, along with the reduction of CO2. In this paper, the biogas dry reforming membrane reactor is proposed to produce H2 for use in fuel cells. Pd/Cu alloy membrane is used to enhance the performance of the biogas dry reforming reactor. This study aims at understanding the effect of operating parameters such as feed ratio of sweep gas, pressure in the reactor, and reaction temperature on the performance of the biogas dr [...]

The impending adverse effects of Global Climate Change encourages the substitution of fossil fuels with non-carbon sources for electricity generation. However, while fossil fuel power plants may generate electric power at demand, the most abundant renewable energy sources-wind and solar-are intermittent or periodically variable. This necessitates the development of adequate energy storage at the utility/grid level. Using actual data for the hourly energy demand in the ERCOT electricity grid, this study examines the [...]

Background: Phylogenetic analysis shows that Pneumocystis have coevolved with their mammalian hosts for millions of years. As a result, infection by Pneumocystis is species specific (i.e. a given Pneumocystis species can infect only a single species of host). This specificity suggests the existence of a Red-Queen dynamic between Pneumocystis and its host. Evidence of this dynamic is provided by the molecular diversity and the elevated rate of non-synonymous versus synonymous (dN/dS) codon substitutions among Pneumo [...]

A conceptual model was developed to create a basis for understanding the risk factors and outcomes associated with dysphagia and to hypothesize the nature of the relationship between certain factors. The conceptual model was developed by two academic speech-language pathologists with ≥10 years research and clinical experience in swallowing and dysphagia in older adults. A comprehensive review of English-language literature was conducted, and relevant, evidence-informed factors associated with dysphagia in older adu [...]

Wilson Disease is a monogenetic disorder of copper metabolism affecting the ATP7B gene. Treatment is lifelong and focuses on removal of copper to arrest disease progression and improve the clinical manifestations of copper toxicity. Currently the only cure is liver transplantation, however, lifelong monitoring and immunosuppressive medications are still needed afterwards. The possibility of introducing functional ATP7B gene through gene therapy provides an exciting potential option for achieving a more permanent cu [...]

The purpose of this convergent mixed methods study was to explore the feasibility of implementing a chair yoga intervention in assisted living facilities (ALFs), evaluating reach, demand, acceptability, practicality, treatment fidelity, and safety. A yoga intervention was implemented twice a week for eight weeks at four different ALFs. Feasibility data were collected in the form of observational data, reflective field notes, and focus groups. Quantitative and qualitative data strands were compared to determine if r [...]

Charge transfer and mobility are essential for electrochemical processes in batteries, which need to be understood in detail for optimization, especially in the case of all-solid-state batteries. Wide line NMR is well-known in solid-state NMR and allows the quantification of ion mobility in ordered crystalline and amorphous structures. Temperature-dependent 23Na-NMR is sensitive to ion mobility via longitudinal relaxation, but also via line analysis and transverse relaxation. As 23Na is a spin 3/2 nucleus, 23Na-NMR [...]
