During the conditioning of the samples as well as during the execution of the creep tests, miniaturized humidity sensors were employed to measure the relative humidity in the concrete pores. The measured creep and shrinkage deformations are the higher, the higher the initial moisture content of the samples, and additionally, the higher the rate at which concrete losses moisture due to a dry ambient environment. The rate of change of the mean relative humidity of the samples was found to scale in a unique manner the rate of drying shrinkage, independent of the moisture content. Based on the mean relative humidity measured in the concrete samples, simple mathematical formulations to predict basic and drying creep are proposed. Assuming that basic creep is influenced by the moisture content, the evaluation of the model suggests that drying creep, drying shrinkage and mean relative humidity follow the same kinetics.

Now, the contributions of psychology to rehabilitation have resulted an integral care for people with disability, but the debate about the conceptualization of disability and the role of disabled people in society still remains; said debate should incorporate new views, particularly those coming from handicapped people.
The influence of the oscillations in skin resistance and peripheral blood flow over health status... more The influence of the oscillations in skin resistance and peripheral blood flow over health status subjective perception was assessed in 30 university students: 15 men and 15 women. Health Survey Short-Form 36 (SF-36) was applied, and DataLab 2000 was utilized to obtain psychophysiological records. Results show that increase in frequency of the skin resistance oscillations influenced the dimension of physical function directly, and the social function inversely. In the same way, being a woman had an inverse influence in physical function and general health. No effects over the other dimensions of SF-36 were observed.

Las variables consideradas fueron el numero de ensayos y la velocidad de la realizacion de los ejercicios. El objetivo fue averiguar si es posible obtener una reduccion en el tiempo de tratamiento observando los efectos obtenidos en una sesion. Para ello se utilizaron replicaciones directas: Se estudiaron tres grupos musculares distintos, cada grupo muscular en un sujeto diferente y en una sola sesion para cada sujeto. En cada sesion se aplicaron distintas combinaciones de valores de las variables. En este estudio participaron tres sujetos y se realizaron analisis de series temporales en dos de los sujetos, constituyendo en el otro sujeto una descripcion de caso. Los resultados sugieren, que el numero de ensayos por sesion puede ser incrementado considerablemente, que el intervalo entre ensayos puede ser reducido, aunque ...

Los participantes se seleccionaron segun ciertos criterios de inclusion y de exclusion, y se les aplico un cuestionario con las caracteristicas psicologicas, psicosociales y psicofisiologicas que se han observado con mas frecuencia en estos trastornos. Se obtuvieron aquellas caracteristicas que tenian una distribucion no aleatoria entre los participantes, las que se agruparon en tres dimensiones, que corresponden a las areas cognitiva, emocional, psicocial y psicofisiologica.

Risk factors such as multiparity, advanced maternal age, prior cesarean delivery, prior myomectomy, placenta previa, or previous uterine evacuation place patients at a higher risk for having abnormal placental implantation. If these patients have a first trimester missed abortion and fail medical management, it is important that providers have a heightened suspicion for a MAP. A 24-year-old G4P3003 with 3 prior cesarean deliveries underwent multiple rounds of failed medical management for a missed abortion. She had a dilation and curettage that was complicated by a significant hemorrhage and ultimately required an urgent hysterectomy. When patients fail medical management for a missed abortion, providers need to assess the patient's risk factors for a MAP. If risk factors are present, a series of specific evaluations should be triggered to rule out a MAP and help further guide management. Early d...

They also use in the social responsibility activities (Kakabadse, Rozuel, & Lee-Davies, 2005; Korhonen, 2002) in the community-corporation involvement (Burke, 1999) that adds value to the latter ones (Rochlin, & Christoffer, 2000, p.1) in regards to the social marketing (Whitcombe, 2009) aiming to the elimination of barriers that hamper the implementation of social programs (McKenzie-Mohr, 2000a, 2000b), or, with a strategic view, in regards to the shared value that benefits community and companies at the same time (Porter & Kramer, 2011). There are, of course, many other ways to incorporate such language in companies.
