Water-filled heat pipe useful at moderate temperatures

Heat pipe is used in the primary heat exchanger for nuclear power plants, as a heat sink for high-power electronic devices, and in a closed-cycle heat rejection mechanism for cryogenic storage tanks. It serves simultaneously as a heat transfer device and as a structural member

Development and Analysis of a Software Package to Quantify In Vivo Polyethylene Wear after Total Hip Arthroplasty

Since the first total hip arthroplasty (THA) in 1938, THA evolved and developed into one of the major concentrations of orthopaedic research. The typical hip implant device used today incorporates a femoral and an acetabular component that serve to replicate the anatomical and mechanical functions of the natural hip joint. However, several problems exist that can effect the function of the implant device. Wear in the polyethylene liner of the acetabular component of the total hip replacement device is known as one of the major factors that affects the longevity of total hip replacement devices. Both manual and computer-aided techniques have been developed to measure linear and volumetric polyethylene wear in two and three-dimensional directions. This study aims to develop a software package that will accurately measure in vivo polyethylene wear after total hip arthroplasty and can be applied to determine the factors that lead to polyethylene wear

Reply to Murrell et al.: Noise matters

The concept of statistical “equitability” plays a central role in the 2011 paper by Reshef et al. (1). Formalizing equitability first requires formalizing the notion of a “noisy functional relationship,” that is, a relationship between two real variables, X and Y, having the form Y=f(X)+η, where f is a function and η is a noise term. Whether a dependence measure satisfies equitability strongly depends on what mathematical properties the noise term η is allowed to have: the narrower one’s definition of noise, the weaker the equitability criterion becomes

Physical Therapy Professionals’ Opioid Knowledge and Attitudes in a Midwestern State: A Cross Sectional Survey

Purpose: To determine perspectives towards opioid use, knowledge on managing an opioid overdose, and awareness towards individuals who use opioids of Indiana physical therapy (PT) professionals. Methods: An online questionnaire was disseminated to PT professionals in Indiana from various practice settings. This questionnaire included two standardized measures, the Opioid Overdose Knowledge Scale (OOKS) and the Opioid Overdose Attitude Scale (OOAS). An additional 12 questions regarding the role of PT and other groups in the opioid crisis as well as opioid education were included. These questions were developed by discussion between investigators as well as feedback from another rehabilitation professional. Descriptive statistics were primarily used to analyze the data. Further investigation via non-parametric tests, including Mann-Whitney U and Kruskal-Wallis tests, were performed to analyze the impact of demographic variables on OOKS and OOAS scores. Results: Of 1840 surveys disseminated, the questionnaire was initiated by 67 PT professionals, while 58 participants completed it. The OOKS score was 30.24 mean (5.67 standard deviation) and the OOAS score was 90.36 (9.36). 93.1% of respondents reported wanting to help in an overdose situation, but 94.8% of respondents also reported needing more training. Only 48.3% of participants received education on the opioid crisis within the last 3 years that significantly impacted their clinical practice. Those who had opioid education in the last 3 years had higher OOKS scores (p = .003) and OOAS scores (p = .002) compared to those who did not receive opioid education. American Physical Therapy Association members had statistically significant higher OOAS scores (p = .005) but not OOKS scores (p = .322). Conclusion: A sample of PT professionals in Indiana surveyed in this study lack knowledge and awareness on opioid use, specifically managing an overdose. While most want to help, further education or training is needed for them to confidently manage these situations
