The 2016 Republican presidential campaign has been based on an overtly anti–Mexican immigrant nativist message, another round in the universalistic versus nativist conflict over the definition of American. Nationally, Latinos exhibit the strong work ethic, avoidance of welfare, positive health outcomes, and long life expectancy of Latinos in California. In the post-millennial generation in the top eleven Latino market areas, Latino presence ranges from being a large majority to being the largest plurality. Latino post-millennials will be instrumental in creating the twenty-first-century definition of American.

In this research, the verification on the torque limiter is completed by using the mechanism of a torque limiter integrated with the infrared optointerrupter feedback detection. Through a shuttle and an infrared optointerrupter, it is meant to determine whether the rotation mechanism is affected by the mechanism of a torque limiter. With this, it is available to determine if any jamming happens. Through the testing verification of physical mechanisms, the feasibility for the torque limiter proposed by this research is conducted. It can avoid current shorting when dead jamming happens. Also, the detection circuits relevant to the detection of motor current feedback can be saved to reduce systematical circuit maintenance and manufacture torque limiters with long life expectancy, higher stability and low cost.

Abstract Bambusa vulgaris is the most commonly encountered bamboo in cultivation in SE Asia but is rarely found in natural forest (although possibly natural, or escaped, naturalized populations exist). It is grown pantropically, and is the only Asian species that is common in the New World. Ease of propagation is the main reason for its success, culms and branches rooting very readily indeed. Infrequency of flowering, failure to produce seed and divert resources away from culm production, and recovery of clumps after flowering are other assets, and may be a result of repeated selection and cloning (Stapleton, 1990). Although not very straight, not easy to split, and inflexible, the culms are thick-walled and initially strong although relatively susceptible to powder-post beetle attack. They find many uses, although structural use is not recommended without preservation to protect against beetles. The ease of propagation, long life expectancy, and high yield make this species better suited to production of pulp and biomass for energy. Susceptibility to bamboo blight is of concern, especially on sites with impeded drainage. Repeated vegetative propagation has resulted in reduced genetic variability. Ornamental clones with all yellow, or yellow striped culms, or shortened, swollen culm internodes ('Wamin') are widely cultivated.

AbstractThe relation between fertility and longevity has always been a subject of study and controversy. Indeed, life expectancy extension is found to be tied to late births. This conclusion can be drawn from social-observational studies like the Long Life Family Study in New England and the New England Centenarian Study on which was found that women whose last birth was after 40 years of age are more likely to live longer. Recently, a group in Israel published a review on animal and human studies that shed some understanding on the cellular mechanisms behind the association between pregnancy and tissue regeneration and repair. These studies shed some understanding to draw biological plausibility on the association between late pregnancy and life expectancy.

Predicting precisely where a crack will develop in a material under stress and exactly when in time catastrophic fracture of the component will occur is one the oldest unsolved mysteries in the design and building of large-scale engineering structures. Fitness considerations for long-life implementation of aerospace composites include understanding phenomena such as fatigue, creep and stress corrosion cracking that affect reliability, life expectancy, and durability of structure. Structural integrity analysis treats the design, the materials used, and figures out how best components and parts can be joined; furthermore, SI takes into account service duty.

Introducción: Los estudiantes universitarios se encuentran en un momento crucial de sus vidas en lo que respecta a la adquisición de un estilo de vida saludable. Para esto es necesario que obtengan un equilibrio entre las demandas universitarias (compromiso académico) y el tiempo libre.Objetivos: Describir las relaciones entre ocio, engagement y salud.Método: Diseño de encuesta cuantitativa, no experimental. 1.142 estudiantes completaron los cuestionarios sobre ocio, salud y engagement. Se realizaron análisis descriptivos, de correlación lineal y ANOVA sobre los datos obtenidos.Resultados: 960 estudiantes participaron en actividades de ocio activo con actividad física durante la semana (3–9 horas) y 1.021 los fines de semana (3–8 horas); 1.084 se dedicaba al ocio activo sin actividad física de lunes a viernes (4–14 horas) y 1.109 los fines de semana (7–16 horas); 1.049 se dedicaron al ocio pasivo todos los días (2–7 horas) y 997 los fines de semana (3–8 horas) de inactividad, mientras que 748 estuvieron inactivos durante la semana (1–5 horas) y 745 los fines de semana (2–4 horas). Las mujeres pasaron menos tiempo libre durante la semana, obtuvieron puntajes más altos de engagement y una peor salud percibida. Encontramos relación negativa entre la salud y el engagement y el ocio.Conclusiones: Los estudiantes estaban comprometidos y gozaban de buena salud, lo que indica que un alto engagement y actividades de ocio están asociadas con una mejor salud percibida. Las universidades deben esforzarse por convertirse en entornos más saludables revisando sus planes de estudio, promoviendo el compromiso y ofreciendo un programa de ocio atractivo.   Introduction: University students are at a crucial time in their lives as regards acquiring a healthy lifestyle. For this it is necessary that they obtain a balance between the times used to the university demands (academic engagement) and the leisure time, as recovery time. Objectives: To describe the relationships between leisure, engagement and health. Method: We employed a quantitative, non-experimental survey design. 1.142 students completed the questionnaires on leisure, health and engagement. Descriptive, linear correlation and ANOVA analyses were performed on the data obtained. Results: 960 students engaged in active leisure with physical activity during the week (3–9 hours) and 1.021 at the weekend (3–8 hours); 1.084 engaged in active leisure without physical activity from Monday to Friday (4–14 hours) and 1.109 at the weekend (7–16 hours); 1.049 engaged in passive leisure every day (2–7 hours) and 997 at the weekend (3–8 hours) idleness, while 748 were idle during the week (1–5 hours) and 745 at the weekend (2–4 hours). Women spent less time of leisure during the week, scored higher of engagement and had poorer perceived health. We found a negative relationship between health and engagement and leisure. Conclusions: Students were engaged and in good health, indicating that high engagement and leisure activities are associated with better perceived health. Universities should strive to become healthier settings by revising their curricula, promoting engagement and offering an attractive leisure programme.
