Abstract The physical factors affecting the force required to pull a cord from the cord-rubber specimen used in a new tire cord adhesion test (TCAT) were investigated using a variety of rubber compounds, specimen cross-sectional areas, and tire cords. Below a limiting cross-sectional dimension, the cord pull-out force was proportional to the square root of cord perimeter, specimen cross-sectional area, and Young's modulus of the rubber, as anticipated from theoretical considerations. The constant of proportionality involved the square root of the energy of adhesion. The value of the energy of adhesion calculated from the proportionality constant was confirmed by an independent peel test.

Abstract A new tire cord adhesion test is reported. Although developed primarily for measuring adhesion of rubber to tire cord, the test is applicable to any cord- or wire-reinforced composite, for example, rubber hose or belting. The specimen is a rubber bar of square cross section containing two partially embedded cord ends opposite each other. Upon the application of sufficient tensile force to the cords, failure is initiated at the tip of the embedded end and proceeds along the cord to the exterior, resulting in pull-out of one of the ends. This result contrasts with the initiation of failure in a specimen of the pull-through type containing a throughgoing cord. In the latter specimen, failure initiates where the cord emerges from the rubber and runs back into the interior. Failure is adhesive when pull-out occurs. Under special conditions cohesive failure (tear) occurs and the specimen is cleaved transversely. Reproducibility is excellent and the test has high discriminating power. A theoretical equation permits calculation of the energy of adhesion.

16 Background: Versions of the Distress Thermometer have been used and validated widely, but studies of ethnically diverse populations has been limited. A modifed version of the Thermometer is used to understand factors affecting an African American(AA), inner-city population in order to improve access and utilization of palliative care services in a large, ethnically diverse metropolitan area. Methods: A cross-sectional study of women recieving cancer therapy in New Orleans, LA in 2013-14 was conducted. Subjects completed modified Distress Thermometer surveys which captured levels of distress and assessed predefined factors that could impact distress.Demographics were collected, and descriptive and comparative analyses were performed. Results: 49 Caucasian and 34 AA subjects were analyzed. Overall distress rating distributions were similar between the two groups. AA subjects cited family factors as a cause of distress more often than Causasians. (p < 0.006) AA subjects were also more likely to indicate difficulty with partners and overall lack of support as stressing factors than Caucasians. In subjects who reported distress scores greater than 4, AA subjects cited emotional and physical factors more frequently than Caucasians as a cause for distress. (p < 0.05) 11.11% AA subjects vs 3.57% Caucasians cited spiritual factors as a cause of distress. Conclusions: AA women with gynecologic cancer are more likely to cite familial, emotional, physical and perhaps spiritual factors as factors affecting distress than Caucasian women. These findings could be used to target Palliative Care resources more effectively in an ethnically diverse population.

Us Findings

This study evaluates the frequency and significance of thrombus formation on the surface of intravascular ultrasound (US) imaging catheters. The investigation includes 63 consecutive patients who underwent 32 arterial and 38 venous intravascular procedures. At the end of the imaging procedure the US findings were observed during withdrawal of the catheter into the introducer sheath. Thrombus formation was demonstrated in 5 (7%). The largest thrombus fragments had a cross-sectional dimension of 2.2×1.0 mm. There was a significant correlation between the incidence of thrombus formation and the occurrence of malign neoplastic disease. No relation was found between the frequency of thrombus formation and the duration of the imaging procedure or the type of US catheter. It is concluded that the thrombogenicity of intravascular US imaging devices is not higher than that of conventional angiographic catheters. The observed “pull-out” thrombi were small and it is unlikely that they could have any clinical significance.

Background:To provide information helps building policy that meets the practical situation and needs of the people with the aim at achieving the goal of universal health insurance coverage, we conducted this study with two objectives (1) To determine the rate of participating health insurance among persons whose enrolment is voluntary in some districts of ThuaThien Hue province; (2) To investigate factor affecting their participation in health insurance. Materials and Methodology:A cross-sectional descriptive study was conducted in three districts / towns / city of ThuaThien Hue in 2014. 480 subjects in the voluntary participation group who were randomly selected from the study settings were directly interviewed to collect information on the social, economic, health insurance participation and knowledge of health insurance. Test χ2 was used to identify factors related to the participation in health insurance of the study subjects. Results:42.5% of respondents were covered by health insurance scheme. Factors related to their participation were the resident location (p = 0.042); gender (p = 0.004), age (p <0.001), chronic disease (p <0.001), economic conditions (p<0.001) and knowledge about health insurance (p <0.001). Conclusion: The rate of participating health insurance among study subjects was low at 42,5%. There was "adverse selection" in health insurance scheme among voluntary participating persons. Providing knowledge about health insurance should be one of solutions to improve effectively these problems. Key words: Health insurance, voluntary, Thua Thien Hue

Background: Good social climate and high work engagement are important factors affecting outcomes in healthcare settings. This study observed the effects of a program called Civility, Respect, and Engagement in the Workplace (CREW) on social climate and staff work engagement in a psychiatric ward of a Japanese hospital. Methods: The program comprised 18 sessions installed over six months, with each session lasting 30-min. Participation in the program was recommended to all staff members at the ward, including nurses, medical doctors, and others, but it was not mandatory. A serial cross-sectional study collected data at four time-points. Nurses (n = 17 to 22), medical doctors (n = 9 to 13), and others (n = 6 to 10) participated in each survey. The analysis of variance was used to evaluate the changes in the following dependent variables, the Essen climate evaluation schema (EssenCES), the CREW civility scale, and the Utrecht work engagement scale (UWES) over time. Result: We found no significant effects. The effect size (Cohen’s d) for EssenCES was 0.35 from baseline to post-installation for all staff members. Effect sizes for EssenCES for medical doctors and UWES for nurses were 0.79 and 0.56, respectively, from baseline to post-program. Conclusions: Differences in social climate and work engagement among Japanese healthcare workers between the baseline and post-installation of the CREW program were non-significant.
