Abstract

Objectives: Due to the high rates of overweight and obesity in Mexican and Puerto Rican women, interventions that target these groups are in great need. The purpose of this cross-sectional study is to explore the role of four cultural variables (acculturation, acculturative stress, ethnic identity, and cultural values) that may help to explain ethnic disparities in correlates of obesity (diet, physical activity, and body image) among Mexican and Puerto Rican women. This paper describes the study design, measures, and initial analyses of participant characteristics, as well as implications for the development of an obesity intervention. Methods: A total of 552 participants contacted the study staff, with 368 completing the oral script and initial eligibility interview. From these, 227 completed the written consent, 199 completed the “Health and Culture” interview, and 186 completed all study components; 42 women completed the qualitative interview. Data for the current study is from the 199 participants who completed the “Health and Culture” interview. Results: Mexican women were younger, more likely to have completed less than a 9th grade education, and more likely to prefer to complete the interview in Spanish (vs. English) compared to Puerto Rican women. In addition, Mexican women were more likely to be in the normal-weight group, be a non-smoker, and not have health insurance compared to Puerto Rican women. Conclusion: Results revealed key initial differences between Puerto Rican and Mexican women which should be considered when developing interventions that address overweight and obesity.

Abstract

Data of this study are about the effects of transgenerational effects of thermal stress on morphometric data (eye diameter, arm length, mantle length, yolk, length, egg length egg wide and wet weight), routine oxygen consumption, oxidant damage (Protein oxidation; PO), antioxidant defense mechanisms (Catalase, glutathione-s-transferase, total glutathione)and esterases (carboxyl esterase and acetylcholinesterase) of embryos spawned by females exposed at 24 and 30°C until spawn. Embryos of both groups of femaleswere spread in two groups: one incubated at 24 and the other at 30°C. Evaluations were grouped in threeembryo stages: organogenesis, activation, and growth.&nbsp

Abstract

The current geopolymers have limited mechanical strength against the effect of tension, which makes them susceptible to brittle failure. However, owing to their potential as a sustainable construction material, there is growing interest in improving the poor mechanical properties of geopolymers. This study experimentally investigated crucial properties of polypropylene-fiberreinforced fly ash-based geopolymer composites. The effects of polypropylene fibers (PPF) addition (0.5%, 1.0% and 1.5% by volume) on the mechanical properties of the geopolymer composites were investigated with respect to compressive and flexural strength, deformation behavior of Young’s and shear moduli, and resilience capacity. In addition, scanning electron microscopy was performed to establish the morphology of the geopolymeric matrix and the fiber–matrix interfacial interaction. The addition of PPF significantly increased the flexural strength: compared with the control, at 7 days it was 27% greater for the 0.5% PPF composite and 65% greater for the 1.0% PPF composite. By 14 days it was 31% and 61% greater, respectively. By contrast, the 1.5% PPF composite had lower strength parameters compared with the control because the fiber dispersion increased the porosity. Similar trends were seen for resilience. The SEM observations showed the dispersion of the fibers and helped elucidate the fiber–matrix interaction mechanism, Peer Reviewed, Postprint (published version)
