Geometry requirements for unsteady aerodynamics in aeroelastic analysis and design

Aircraft geometry requirements for unsteady aerodynamic computations are discussed and differences between requirements for steady and unsteady flow are emphasized within the framework of a general potential-flow aerodynamic formulation. Its implementation in a computer program called SOUSSA (Steady, Oscillatory, and Unsteady Subsonic and Supersonic Aerodynamic is detailed

Diffusion and Home Range Parameters from Rodent Population Measurements in Panama

Simple random walk considerations are used to interpret rodent population data collected in Hantavirus-related investigations in Panama regarding the short-tailed cane mouse, \emph{Zygodontomys brevicauda}. The diffusion constant of mice is evaluated to be of the order of (and larger than) 200 meters squared per day. The investigation also shows that the rodent mean square displacement saturates in time, indicating the existence of a spatial scale which could, in principle, be the home range of the rodents. This home range is concluded to be of the order of 70 meters. Theoretical analysis is provided for interpreting animal movement data in terms of an interplay of the home ranges, the diffusion constant, and the size of the grid used to monitor the movement. The study gives impetus to a substantial modification of existing theory of the spread of the Hantavirus epidemic which has been based on simple diffusive motion of the rodents, and additionally emphasizes the importance for developing more accurate techniques for the measurement of rodent movement.Comment: 18 pages, 5 figure

Analysis of nuclear waste disposal in space, phase 3. Volume 1: Executive summary of technical report

The objectives, approach, assumptions, and limitations of a study of nuclear waste disposal in space are discussed with emphasis on the following: (1) payload characterization; (2) safety assessment; (3) health effects assessment; (4) long-term risk assessment; and (5) program planning support to NASA and DOE. Conclusions are presented for each task

Analysis of nuclear waste disposal in space, phase 3. Volume 2: Technical report

The options, reference definitions and/or requirements currently envisioned for the total nuclear waste disposal in space mission are summarized. The waste form evaluation and selection process is documented along with the physical characteristics of the iron nickel-base cermet matrix chosen for disposal of commercial and defense wastes. Safety aspects of radioisotope thermal generators, the general purpose heat source, and the Lewis Research Center concept for space disposal are assessed as well as the on-pad catastrophic accident environments for the uprated space shuttle and the heavy lift launch vehicle. The radionuclides that contribute most to long-term risk of terrestrial disposal were determined and the effects of resuspension of fallout particles from an accidental release of waste material were studied. Health effects are considered. Payload breakup and rescue technology are discussed as well as expected requirements for licensing, supporting research and technology, and safety testing

Cultures of Nutrition: Classification, Food Policy, and Health

Nutrition policymakers frequently treat their knowledge of nutrition as acultural and universal. We analyze food guidelines in Mexico and Guatemala to draw attention to embedded, but often unrecognized, cultural values of standardization and individual responsibility. We suggest that nutrition policy would be improved by attending to the cultural values within nutrition science, and that nutrition guidelines should attend not only to other people’s cultures but to what we are calling “cultures of nutrition.” We conclude by offering an example of an adaptive approach to policy-making that may be useful for handling situations where many different cultures of nutrition collide

A five year record of high-frequency in situ measurements of non-methane hydrocarbons at Mace Head, Ireland

Continuous high-frequency in situ measurements of a range of non-methane hydrocarbons have been made at Mace Head since January 2005. Mace Head is a background Northern Hemispheric site situated on the eastern edge of the Atlantic. Five year measurements (2005–2009) of six C<sub>2</sub>–C<sub>5</sub> non-methane hydrocarbons have been separated into baseline Northern Hemispheric and European polluted air masses, among other sectors. Seasonal cycles in baseline Northern Hemispheric air masses and European polluted air masses arriving at Mace Head have been studied. Baseline air masses show a broad summer minima between June and September for shorter lived species, longer lived species show summer minima in July/August. All species displayed a winter maxima in February. European air masses showed baseline elevated mole fractions for all non-methane hydrocarbons. Largest elevations (of up to 360 ppt for ethane maxima) from baseline data were observed in winter maxima, with smaller elevations observed during the summer. Analysis of temporal trends using the Mann-Kendall test showed small (<6 % yr<sup>−1</sup>) but statistically significant decreases in the butanes and <i>i</i>-pentane between 2005 and 2009 in European air. No significant trends were found for any species in baseline air

Collaborative knowledge sharing in developing and evaluating a training programme for health professionals to implement a social intervention in dementia research

Purpose: This study aims to explore the utility of collaborative knowledge sharing with stakeholders in developing and evaluating a training programme for health professionals to implement a social intervention in dementia research. Design/methodology/approach: The programme consisted of two phases: 1) development phase guided by the Buckley and Caple’s training model and 2) evaluation phase drew on the Kirkpatrick’s evaluation model. Survey and interview data was collected from health professionals, people with dementia and their supporters who attended the training programme, delivered or participated in the intervention. Qualitative data was analysed using the framework analysis. Findings: Seven health professionals participated in consultations in the development phase. In the evaluation phase, 20 intervention facilitators completed the post one-day training evaluations and three took part in the intervention interviews. Eight people with dementia and their supporters from the promoting independence in dementia feasibility study participated in focus groups interviews. The findings show that intervention facilitators were satisfied with the training programme. They learnt new knowledge and skills through an interactive learning environment and demonstrated competencies in motivating people with dementia to engage in the intervention. As a result, this training programme was feasible to train intervention facilitators. Practical implications: The findings could be implemented in other research training contexts where those delivering research interventions have professional skills but do not have knowledge of the theories and protocols of a research intervention. Originality/value: This study provided insights into the value of collaborative knowledge sharing between academic researchers and multiple non-academic stakeholders that generated knowledge and maximised power through building new capacities and alliances
