Hypoxia has been defined as conditions with lower than normal oxygen availability. Altitude exposure and acclimatization have been areas of research for a considerable time. The immediate (acute) effects of lowered ambient pressure of oxygen (PO2) pertaining to the human response and the adaptations to prolonged exposure (chronic) are complex. Several systems (i.e., cardiovascular, pulmonary, and endocrine) react to the hypoxia associated with altitude exposure. Adding to the complexity, these systems rarely react in isolation but rather interact to allow the work of the individual to be accomplished in this type of environment. While generalities exist relating to acute and chronic adaptations (acclimatization) to altitude exposure, current evidence indicates individual responses may facilitate or hinder the acclimatization process. Responders and non-responders have been identified in the literature during attempts to understand the human response to a lowered partial pressure of oxygen. This review summarizes the affects of acute and chronic exposure to altitude as it relates to exercise and work output. Several sub-categories will be addressed. Included in these categories are the following: (a) acute and chronic exposure; (b) performance and length of events; (c) substrate utilization; and (d) various adaptations associated with various increasing altitudes. While much research has been conducted regarding living high/training low (LHTL) scenarios, this review will only discuss findings associated with acute and chronic exposure to altitude. Thus, the purpose of this brief review is to summarize two basic tenets of altitude and exercise: (a) acute exposure response; and (b) chronic adaptations. Source

Gunshot wounds are the third-leading cause of injury-related death nationwide. Most people with gunshot injuries undergo diagnostic imaging to evaluate their injuries in the clinical or forensic setting. Radiologic technologists must be knowledgeable about common injuries associated with gunshot wounds. Digital radiography and computed tomography play essential roles in the assessment of gunshot injuries. When clinically indicated, magnetic resonance imaging also is a valuable imaging modality for evaluating these injuries. Radiologic technologists should obtain quality images to assist with proper assessment of gunshot injuries. © 2016 American Society of Radiologic Technologists. Source

We test the canonical model of international environmental agreements (IEAs) in a laboratory setting with asymmetric agents. IEA participation represents coalition formation and public good provision where there are gains to cooperation, but an incentive to free-ride. We test four competing methods of dividing the coalition's worth: a recently proposed optimal rule which accounts for subjects' payoffs as a single free-rider, the Shapley value, the Nash bargaining solution, and an equal split. Each treatment generates the theoretically predicted coalition size more often than not. The shares of the potential gains to cooperation achieved by each rule are: 51, 36, 40 and 13%, respectively. These results highlight the importance of using an optimal rule to improve IEAs, and more broadly for voluntary public good provision. © 2011 Springer Science+Business Media B.V. Source

Purpose Patient satisfaction with other midlevel providers has been thoroughly examined, but patient satisfaction with radiologist assistants (RAs) has yet to be explored. The goal of this study was to determine the level of patient satisfaction with the care provided by RAs in the United States. Methods Patient satisfaction was measured using a custom-designed satisfaction survey. Twenty RAs volunteered to distribute surveys to patients, or family members of patients, who had diagnostic or therapeutic procedures performed in a variety of clinic or hospital radiology settings. Demographic and procedural data also were collected, and results were tabulated from 359 completed self-administered surveys. Results Respondents were satisfied with the care they or a family member received from the RA. The mean score for overall satisfaction was 4.89 on a 5-point Likert scale. The mean score in the domain of communication was 4.83. The score for RA professionalism was 4.91. RAs scored highly across all categories of procedures performed. No statistically significant differences were noted with overall patient satisfaction based on patient age and gender, procedure type, and whether the respondent was a family member or patient. No differences in responses were noted based on the RA's years of experience, facility size, or location. Discussion This study indicated a high level of patient satisfaction with health care services provided by RAs in diagnostic and interventional imaging procedures. In general, surveyed respondents rated RAs highly for their professionalism and thoroughness. This study also demonstrated that RAs who volunteered for the study are performing a variety of radiologic and interventional procedures with high overall patient satisfaction, that RAs perform procedures in a multitude of hospital and clinic settings in various geographic regions, and that they work with patients of all ages. Conclusion Results showed that patients gave RAs a high overall satisfaction rating for all the procedures performed. These findings are consistent with patient satisfaction surveys of other types of physician extenders in medicine. The instrument, methods, and findings of this study can be used as initial data for the continued evaluation and monitoring of the RA's role in health care. © 2014 American Society of Radiologic Technologists.

Mathematical Methods in the Applied Sciences

A demonstration method is presented, which will ensure the existence of positive global solutions in time to the reaction-diffusion equation -u t+Du+up=0 in ℝn×[0,∞), for exponents p≥3 and space dimensions n≥3. This method does not require the initial value to have a specific uniform smallness condition, but rather to satisfy a bell-like form. The method is based on a specific upper solution, which models the diffusion process of the heat equation. The upper solution is not self-similar, but does have a self-similar-like form. After transforming the reaction-diffusion problem into an equivalent one, whose initial value is uniformly very small, a local solution is obtained in the time interval [0, 1] by the use of this upper solution. This local solution is then extended to [0,∞) through an infinite sequence of extensions. At each step, an appropriate change of variables will transform the extension into a problem nearly identical to the local problem in [0, 1]. These transformations exploit the diffusive and self-similar-like nature of the upper solution. Copyright © 2009 John Wiley & Sons, Ltd. Source
