Rainfall-induced differential settlements of foundations on heterogeneous unsaturated soils

This study stochastically investigates the rainfall-induced differential settlement of a centrally loaded, rigid strip foundation on an unsaturated soil with spatially varying values of either preconsolidation stress or porosity. The differential settlement (between the two foundation ends) is calculated at various times during rainfall by way of a coupled, hydro-mechanical, finite-element analysis. The Barcelona basic model describes the mechanical behaviour of the soil, and the van Genuchten relationships describe water retention and permeability. The variability of soil properties is modelled by means of random fields with spatial correlation in the framework of a Monte Carlo simulation. The study demonstrates that the occurrence of rainfall-induced differential settlements can be consistently analysed using concepts of unsaturated soil mechanics and random field theory. Results show that differential settlements can be vastly underpredicted (or even completely missed) if random heterogeneity and partial saturation are not simultaneously considered. The variation of differential settlements and their statistics during the rainfall depend on the magnitude of the applied load and the statistics of soil variability. Moreover, the transient phase of infiltration and a spatial correlation length equal to the width of the foundation pose the highest risk of differential settlement

Conversatorio «Ética y corrupción en la función pública»

La Universidad Peruana de Ciencias Aplicadas (UPC), a través de la Dirección de Gestión del Conocimiento, organizó el conversatorio denominado: «Ética y corrupción en la función pública», el cual se celebró el 5 de mayo del presente año en el campus Monterrico de la Universidad Peruana de Ciencias Aplicadas (UPC) Lima, Perú. Los ejes temáticos que se abordaron fueron los siguientes: ética de la función pública en las organizaciones públicas y en la formación de funcionarios; corrupción desde el punto de vista del desarrollo de la infraestructura pública; e impacto de la corrupción desde el punto de vista de las instituciones políticas, económicas, educativas y sociales, entre otras. Los participantes especialistas fueron los siguientes: Francisco Merino Amand, doctor por la Universidad de Valencia (España) del programa Ética y Democracia, coordinador de cursos en el Departamento de Humanidades de la UPC y autor del libro «Ética para la función pública»; Elsa Carrera Cabrera, ingeniera civil especialista en estructuras de puentes y proyectos viales, ministra de Transportes, Comunicaciones, Vivienda y Construcción entre los años 1996 y 1997 y docente cursos de pregrado y posgrado en la UPC; Ana Isabel Rapún Ruiz, candidata doctoral en el Programa de Filosofía de la Acción y Dirección de organizaciones, IESE Bussiness School, Universidad de Navarra, profesora a tiempo completo de los cursos Ética y Responsabilidad Social Empresarial y coordinadora académica de la carrera de Administración y Recursos Humanos de la Facultad de Negocios de la UPC; Andrés Franco Urdanegui, décimo superior del noveno ciclo de la carrera de Derecho y practicante en el Estudio Flint Abogados; y Miguel Saravia López de Castilla, director de Gestión del Conocimiento de la UPC y presidente de Altamira, Grupo de Bibliotecas Académicas Peruanas

Fabricação digital na América do Sul: um mapeamento de linhas de ação a partir da arquitetura e urbanismo

XIX Congresso da Sociedade Ibero-americana de Gráfica Digital 2015. De 23 a 27 de Novembro de 2015. Universidade Federal de Santa Catarina, Florianópolis/SC, BrasilThe article presents a mapping of digital fabrication laboratories in South America from the architecture and urbanism field. First, it draws a brief context of implementation of facilities and growing of expertise highlighting economic, academic and cultural aspects. Second, it presents some data mapped from 31 laboratories of the region, as infrastructure, and correlations between uses and applications. Third, it organizes the mapped laboratories in two significant approaches for the region’s context: works focused on technological development and actions directed to the social and environmental development. Fourth, it infers some possible steps of the field in the region in the near future

Psychometric Properties of the Pittsburgh Sleep Quality Index (PSQI) in a Cohort of Peruvian Pregnant Women.

STUDY OBJECTIVES: We sought to evaluate the construct validity and factor structure of the Spanish-language version of the Pittsburgh Sleep Quality Index (PSQI) among pregnant Peruvian women. METHODS: A cohort of 642 women were interviewed at ≤ 16 weeks of gestation. During interview, we ascertained information about lifestyles, demographics, sleep characteristics, and mood symptoms. Stress induced sleep disturbance, depressive symptoms, and anxiety symptoms were evaluated using the Ford Insomnia Response to Stress Test (FIRST), Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder-7 (GAD-7) assessment scales, respectively. Consistency indices, exploratory and confirmatory factor analyses, correlations, and logistic regressions were used. RESULTS: Both exploratory and confirmatory factor analyses indicated a three-factor solution: sleep quality, sleep efficiency, and sleep medication. We observed significantly positive correlations of the PSQI with the FIRST (0.42), the PHQ-9 (0.49), and the GAD-7 (0.46). Poor sleepers (PSQI global score > 5) had significantly increased odds of experiencing stress-induced sleep disturbance (odds ratio, OR = 3.57; 95% CI: 2.40, 5.31), depression (OR = 5.48; 95% CI: 3.58, 8.37), and generalized anxiety disorder (OR = 4.57; 95% CI: 3.08, 6.76). CONCLUSION: The Spanish-language version of the PSQI instrument was found to have good construct validity among pregnant Peruvian women. Consistent with some other studies, the PSQI was found to have a three-factor structure. Further assessment and validation studies are needed to determine whether the three, factor-specific scoring of the PSQI is favored over the PSQI global score in diverse populations.This was not an industry supported study.
