However, the analysis of field case histories suggests that the influence of foundation bearing pressure may also be a significant factor influencing such phenomena. Data from 24 buildings that suffered settlement and tilting as a consequences of soil liquefaction during the February 27th 2010 Maule earthquake in Chile, are herein analyzed and compared with data from other earthquakes. Although case history data play a crucial role in geotechnical earthquake engineering, in many cases their analysis is limited to speculation therefore experimental verification is often required. Thanks to the significant development in dynamic geotechnical centrifuge modelling in the last 30 years, we are today able to carefully reproduce field motions enhancing the reliability of experimental results. This is the case for the centrifuge tests discussed in this paper, which have been the fi...

Se realizó un muestreo dirigido para analizar la prevalencia de parásitos gastrointestinales en 35 individuos (22 hembras y 13 machos), a través de la técnica coproparasitaria de Teuscher. Solo una muestra de una tortuga hembra resultó positiva (2.85%), correspondiendo a una especie no determinada de coccidia.

Research paper thumbnail of Deprivation Index and Lifestyle: Baseline Cross-Sectional Analysis of the PREDIMED-Plus Catalonia Study

This study involved 1512 participants (759 (52.2%) women) between 55 and 80 years with overweight/obesity and metabolic syndrome assigned to 137 primary healthcare centers in Catalonia, Spain. CSI and lifestyle (diet and physical activity) were assessed. Multiple linear regression or multinomial regression were applied to the data. Cluster analysis was performed to identify dietary patterns. The multiple linear regression model showed that a high deprivation index was related to a higher consumption of refined cereals (11.98 g/d, p-value = 0.001) and potatoes (6.68 g/d, p-value = 0.001), and to a lower consumption of fruits (−17.52 g/d, p-value = 0.036), and coffee and tea (−8.03 g/d, p-value = 0.013). Two a posteriori dietary patterns were identifie...

Los objetivos de este estudio fueron evaluar los estilos de vida (dietéticos y actividad física), y su asociación con el Índice de Masa Corporal (IMC) en adolescentes.Material y métodos: Se realizó un estudio de tipo transversal sobre estilos de vida en adolescentes escolares. Se recogieron características sociodemográficas, datos clínicos, medidas antropométricas, hábitos dietéticos y de actividad física. Se utilizó una Regresión Lineal Múltiple para valorar la asociación entre los estilos de vida y el IMC, ajustados a posibles factores de confusión: sexo, edad, horas de sueño y tabaquismo.Resultados: Se analizaron 129 adolescentes (51,94% chicos) con una media de edad de 14,88 años. La prevalencia de exceso de peso fue del 32,80%, siendo mayor en los chicos comparados con las chicas. Un 59,70% de l...

Participants were a subsample of 541 cohabitants of the PREDIMED-Plus study. Adherence to the MedDiet, physical activity, anthropometric measurements, family function, and social support were assessed. Multiple linear regressions were applied to the data. Partners of the PREDIMED-Plus participants had higher adherence to the MedDiet compared to their sons/daughters (9.0 vs. 6.9 points). In comparison to partners with low adherence to the MedDiet, partners with high adherence were older, practiced more physical activity, ate more frequently with the PREDIMED-Plus participants, and had better family function (adaptability item). Compared to physically active partners, very active ones ...

El objetivo del estudio fue determinar la presencia de anticuerpos séricos contra C. psittaci en 30 loros provenientes de tres criaderos privados de la región del Biobío, mediante la detección de anticuerpos tipo IgG a través un ELSA comercial (ELISA InmunoComb®). Tres loros adultos (3/24) resultaron seropositivos (10% de prevalencia) y ningún juvenil (0/6). Los psitacidos positivos corespondieron a una cachaña (Enicognathus ferrugineus), un choroy (Enicognathus leptorhynchus) y una amazona (Amazonas pretrei), todos provenientes del mismo criadero. La cachaña y el choroy son especies nativas de Chile.

Objective To evaluate the effectiveness of an action grounded in physical activity in heath state of users in the Unified Health System [Sistema Único de Saúde – SUS] of the Family Health Strategy of the Municipality of Iguaí (BA). Methodology Intervention study with an epidemiological approach, studies in the community, sample of 30 registered users on FHU aged ≥ 60 years old. Data collection was performed using an instrument that contained sociodemographic information, and evaluation of blood pressure and glucose levels, weight and height for later calculation of Body Mass Index (BMI).
