1 LAMB WAVE STIFFNESS CHARACTERIZATION OF COMPOSITES UNDERGOING THERMAL-MECHANICAL AGING

INTRODUCTION The introduction of new, advanced composite materials into aviation systems requires a thorough understanding of the long term effects of combined thermal and mechanical loading upon those materials. Analytical methods investigating the effects of intense thermal heating combined with mechanical loading have been investigated by Griffis, et al. [1] and Chen, et al. [2]. Schubbe and Mall [3] and Castelli, et al. [4] have experimentally investigated both in-phase (maximum temperature at maximum load) and out-of-phase (maximum temperature at minimum load) thermal-mechanical cycling on composites. Both authors found that the damage mechanisms and fatigue lives were dependent on test parameters as well as stress levels. Castelli, et al. [4] identified matrix dominated failure modes for out-of-phase cycling and fiber dominated damage modes for in-phase cycling. In recent years, ultrasonic methods have been developed that can measure the mechanical stiffness of composites. To he

Using pictures to convey health information: A systematic review and meta-analysis of the effects on patient and consumer health behaviors and outcomes

Item does not contain fulltextOBJECTIVE: Assess the effect of pictorial health information on patients' and consumers' health behaviors and outcomes, evaluate these effects in lower health literacy populations, and examine the attributes of the interventions. METHODS: We included randomized controlled trials (RCTs) that assessed the effect of pictorial health information on patient and consumer health behaviors and outcomes. We conducted a meta-analysis of RCTs that assessed knowledge/understanding, recall, or adherence, and a subgroup analysis of those outcomes on lower health literacy populations. We narratively reviewed characteristics of pictorial health interventions that significantly improved outcomes for lower health literacy populations. RESULTS: From 4160 records, we included 54 RCTs (42 in meta-analysis). Pictorial health information moderately improved knowledge/understanding and recall overall, but largely increased knowledge/understanding for lower health literacy populations (n = 13), all with substantial heterogeneity. Icons with few words may be most helpful in conveying health information. CONCLUSION: Our results support including pictures in health communication to improve patient knowledge. Our results should be interpreted with caution considering the significant heterogeneity of the meta-analysis outcomes. PRACTICE IMPLICATIONS: Future research should assess which types and characteristics of pictures that best convey health information and are most useful and the implementation and sustainability in healthcare contexts.
