    The pervasiveness, broad reach, and processing capabilities of consumer technologies, including the internet and smartphone devices, has driven the rapid development of research and commercial applications meant to promote physical activity. Unfortunately, researchers have found that commercial physical activity applications (apps) are not often effective, and are not typically evidence-based. The purpose of this study, which was guided by the multiphase optimization strategy (MOST), was to test the individual and combined efficacy of two theory-driven smartphone app modules designed to promote physical activity: guided hierarchical goal setting and points-based feedback. Participants (N = 116) were recruited to participate in a 12-week home-based exercise program, and randomly assigned to one of four conditions. All individuals received a base-app, which contained three components common to eHealth interventions: physical activity tracking, individualized feedback, and weekly theory-based educational modules. One group received this app alone; a second received the base-app plus a points-based feedback module which awarded points, levels, and badges for engaging in physical activity and other in-app functions; a third received the base-app plus a guided goal setting component which aided individuals in setting both distal and proximal physical activity goals by providing goal recommendations and windows that urged gradual progression; and a fourth condition that received all app components. Results demonstrated that individuals in all conditions increased accelerometer-measured moderate to vigorous physical activity (MVPA) by more than 11 minutes per day across the intervention period, while those with access to the points-based feedback module demonstrated higher levels of MVPA when compared to those without the module. Additionally, these individuals demonstrated more favorable outcomes on a number of psychosocial measures (i.e., barriers self-efficacy, exercise self-efficacy, perceived goal setting ability, outcome expectations) and app usage across the intervention. Those with access to in-app goal setting also had higher levels of app usage relative to those without the component. Overall, these findings provide important information for those interested in developing apps aimed at improving physical activity, and lay the groundwork for additional research.Submission original under an indefinite embargo labeled 'Open Access'.

    Characterization of velocity and shear rate distribution in a continuous mixer

    No full text
    Computers simulations have been increasingly used to model mixing for uses in many industries. These simulations have given much insight into the mixing that takes place in different types of mixers. However, most computer simulations are unvalidated. Experiments have not been performed on the same systems to compare the results therefore the accuracy of a simulation is not precisely known. Validation is most important in complex systems or when working with fluids of a non-Newtonian nature. Understanding the mixing that takes place within the mixer allows for changes to be made to the mixer for different materials and aids in mixer design. In order to quantify the mixing taking place in a Readco two inch continuous processor, laser Doppler anemometry was used to measure fluid velocity. This velocity was compared to computer simulation results and was used to calculate the shear rate, length stretch, area stretch and mixing efficiency at different points within the mixer. With this information, the accuracy of the computer simulations was determined. Differences among the mixing of three fluids with different rheology were found. The mixing taking place in different areas of the mixer was assessed. Shear thinning fluids were found to be better mixed with the paddle configuration used. The fluids were mixed best in the intermeshing region and between the tip of the paddle and the barrel wall.M.S.Includes bibliographical references (p. 88-90)by Lindsay M. Fannin

    Artful Lives: The Francis Watts Lee Family and their Times

    No full text
    Francis Watts Lee and his family hold a special place in the history of American photography. F. Holland Day completed a series of remarkable photographs of Lee’s daughter Peggy, and the striking portrait of the child and her mother titled Blessed Art Thou among Women is one of Gertrude Käsebier’s most iconic compositions. In Artful Lives, Patricia J. Fanning uses these and other significant images as guideposts to explore the Lee family and the art and culture of their age. A social reform advocate, Francis Watts Lee was an artistic photographer and a talented printer, part of the circle of avant-garde artists and intellectuals who formed Boston’s bohemia. He married twice, first Agnes Rand, an award-winning poet and children’s book author, and later, after their divorce, Marion Lewis Chamberlain, a librarian and MIT-trained architect. Francis and Agnes’s eldest daughter, Peggy, who was so integral to the work of pioneer Pictorialists, died at age seven of juvenile diabetes. Her sister, Alice, who lost her hearing in infancy, became a wood carver and sculptor. Utilizing previously unknown family archives and institutional sources, Fanning traces the Lee family’s story in the context of major artistic, political, social, and religious trends, including the Arts and Crafts movement, Christian Socialism, and Aestheticism, while also showing how their experiences reflected the national culture’s evolving conceptions of family, gender, childhood, medicine, deaf education, and mourning. This richly drawn and gracefully written account of one family informs our understanding of this vibrant era, in Boston and well beyond.https://vc.bridgew.edu/fac_books/1149/thumbnail.jp

    Jason Fanning,1 Amber Keller Brooks,2 Megan Bennett Irby,1 Kindia Williams N’Dah,1 W Jack Rejeski1 1Department of Health and Exercise Science, Wake Forest University, Winston-Salem, NC, USA; 2Department of Anesthesiology, Wake Forest University School of Medicine, Winston-Salem, NC, USACorrespondence: Jason Fanning, Department of Health and Exercise Science, Wake Forest University, 1834 Wake Forest Road, Winston-Salem, NC, 27109, USA, Email [email protected]: One’s amount, intensity, and distribution of physical activity may have implications for whether it has positive or negative effects on pain and quality of life for older adults living with chronic pain. Thus, we investigated baseline patterns of stepping related to pain symptoms and health-related quality of life at baseline and over a 12-week follow-up period.Patients and Methods: Participants were low-active older adults (69.54± 6.74 years) with obesity and chronic pain who enrolled in one of two randomized controlled trials. Participants completed measures of pain intensity, interference, and health-related quality of life and wore an accelerometer for 7 days at baseline and week 12. Functional principal components analysis identified patterns of within-day stepping behavior at baseline, and linear regressions were used to investigate how these component scores related to pain and health-related quality of life at baseline and over 12 weeks.Results: Two patterns were extracted; one describing more vs less stepping and the second capturing movement later vs earlier in the day. More baseline stepping was associated with better physical functioning (B=0.148, p< 0.001) and energy (B=0.073, p=0.033), while a later start in the day was associated with worse social functioning (B=− 0.193, p=0.031). More stepping at baseline predicted positive changes in physical functioning (B=0.094, p=0.019), emotional role limitations (B=0.132, p=0.049), energy (B=0.112, p< 0.001), social functioning (B=0.086, p=0.043), pain (B=0.086, p=0.009), general health (B=0.081, p=0.003) and pain intensity (B=− 0.039, p=0.003). A later start to the day was associated with worsening physical functioning (B=− 0.229, p< 0.001), physical (B=− 0.282, p=0.047) and emotional role limitations (B=− 0.254, p=0.048), general health (B=− 0.108, p=0.041), and pain interference (B=0.055, p=0.043).Conclusion: Findings suggest there is value in activity patterns as an indicator for additional behavioral intervention, as those who move little and/or delay daily movement are likely to experience subsequent decrements in quality of life and pain symptoms.Keywords: pain, patterns, physical activity, accelerometry, quality of lif

    OPTIMIZING STRESS MANAGEMENT IN COLLEGE STUDENTS

    Yuechun Yao, Jason Fanning. Wake Forest University, Winston Salem, NC. Background: College students encounter new and powerful stressors, predisposing them to a lifetime of poor health and unhealthy behaviors; thus, finding low-impact and attainable methods of stress management is of high importance for this population. The purpose of this study is to examine the impact on stress of a single bout of three potential stress intervention components—yoga, progressive muscle relaxation (PMR), and deep breathing technique (DBT)—delivered alone and in combination. Methods: A 30-minute stress reduction intervention session was conducted for 40 undergraduate college students who were randomized to one of 8 combinations of yoga (yes or no), PMR (yes or no), and/or DBT (yes or no). Participants self-reported stress via the perceived stress scale (PSS), and positive and negative affect via the positive and negative affect schedule (PANAS) before and following the session. We investigated component main effects and interactions via ANCOVA, controlling for pre-session stress or affect. Result: Participants were 20.6 ± 1.19 years of age on average, and 70% were female. Regarding PSS, an ANCOVA controlling for baseline PSS revealed a significant yoga x PMR interaction (F=4.67, p=0.04, η2=0.14), and an investigation of interaction plots revealed that the combination of yoga and PMR resulted in the lowest stress levels compared to all other combinations. Regarding positive affect, the ANCOVA controlling for baseline positive affect revealed an approached significant yoga x DBT interaction (F=3.76, p=0.06, η2=0.12) such that the combination of yoga and DBT resulted in the highest positive affect compared to all other combinations. Conclusions: These results support the value of a single session of yoga in combination with either PMR and/or DBE for enhancing recovery from stress and positive mood in college students.

    Printed circuit heat exchangers (PCHE) are designed to improve heat recovery and energy saving in supercritical CO2 (S-CO2) power cycles. In the current study, a modified channel PCHE is proposed based on the regular straight channel and a zigzag channel. The thermal–hydraulic performance of four different types of PCHE is numerically investigated and the methods are verified by both experimental and numerical results. The numerical results are presented for a Reynolds number based on the inlet conditions between 5 000 and 25 000. From the numerical results, the local pressure loss and local heat transfer coefficients are analyzed and discussed. Subsequently, the global Nusselt number and Fanning friction coefficients are discussed. It is found that the inserted straight section contributes to uniform flow, resulted in significant pressure loss reduction with a slight decrease in heat transfer. The modified channel can reduce the Fanning friction coefficient by 33.1%-84.7% while the global Nusselt number reduction is about 3.6%-30.3%. This leads to a maximum performance evaluation criterion (PEC) enhancement of 45.9%.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Energy TechnologyMarine and Transport Technolog

    No full text
    Background/Aims: Cronobacter spp. have been identified as being of considerable risk to neonates. The occurrence of organism in infant formulas is therefore of considerable interest. Methods: The occurrence of Cronobacter spp. in infant feeds (formulas and fortified cow’s milk) was determined using most probable number (MPN) analysis, and from formula preparation utensils. Ninety nine samples were analyzed, of which 42 were unopened cans of powdered infant formula (PIF), 25 reconstituted infant formulas in feeding bottles, 27 utensils used from the preparation of infant formula, and 5 samples of fortified cow’s milk. Presumptive Cronobacter spp. isolates were identified using the 7 allele multilocus sequence typing (MLST) scheme. Results: C. sakazakii, C. malonaticus and C. muytjensii were recovered from PIF. Although the incidence of Cronobacter in PIF was 29% (12/42), the level was low with an average of 0.54 MPN/100g. According to MLST profiling, C. sakazakii was the most frequently isolated Cronobacter species, and C. sakazakii ST4 (associated with neonatal meningitis) was recovered from 2/42 PIF samples at 0.51 and 0.92 MPN/100g. Conclusions: Cronobacter spp. can be isolated from PIF and therefore strict hygienic practices during PIF preparation are important to minimize neonate exposure and reduce the risk of severe infections
