La prevención en municipios de población reducida. ¿Es necesario adaptar estrategias preventivas de municipios mayores?
2009
Objetivo: El objetivo del presente trabajo fue analizar las percepciones y actitudes de los jóvenes de municipios entre 5.000 y 20.000 habitantes de la Comunidad Valenciana respecto al consumo de drogas y su valoración sobre las actuaciones preventivas realizadas.Material y método: Se utilizó el modelo de Estimación Rápida, Intervención y Evaluación, combinando técnicas cuantitativas y cualitativas. Se realizó un análisis estadístico de los datos cuantitativos, así como un análisis de contenido de los cualitativos.Resultados: El consumo de drogas sigue un patrón normalizado de consumo. Existe una baja percepción de riesgo de las sustancias y una alta disponibilidad de las mismas, especialme…
Análisis de necesidades y evaluación de recursos socio-sanitarios que dan respuesta a las emergencias sociales en la ciudad de Valencia. Propuesta de…
2015
Las situaciones de emergencia, en una sociedad tan compleja y desarrollada como en la que vivimos, no se limitan exclusivamente a aquellas en las que se pone en riesgo inmediato la integridad física de la persona (salud y seguridad). El ciudadano de hoy solicita respuesta inmediata ante otro tipo de necesidades más complejas como es la pérdida de autonomía personal y la necesidad de protección social. En este sentido, nos encontramos que cada vez toma un mayor peso el concepto de emergencia social, entendida como aquella situación que puede desembocar en estados de vulnerabilidad y desprotección social, donde se hace necesaria una atención inmediata que mitigue, en la medida de lo posible, …
Application of the General Model "Biological Nutrient Removal Model No.1" to upgrade two full-scale WWTPs
2012
In this paper, two practical case studies for upgrading two wastewater treatment plants (WWTPs) using the general model BNRM1 (Biological Nutrient Removal Model No. 1) are presented. In the first case study, the Tarragona WWTP was upgraded by reducing the phosphorus load to the anaerobic digester in order to minimize the precipitation problems. Phosphorus load reduction was accomplished by mixing the primary sludge and the secondary sludge and by elutriating the mixed sludge. In the second case study, the Alcantarilla WWTP, the nutrient removal was enhanced by maintaining a relatively low dissolved oxygen concentration in Stage A to maintain the acidogenic bacteria activity. The VFA produce…
Nitrous oxide emission from a moving bed membrane biofilm reactor: the effect of the sludge retention time
2016
The aim of the present study was to investigate the nitrous oxide (N2O) emissions from a University of Cape Town (UCT) moving bed membrane bioreactor pilot plant. An experimental campaign was carried out during 60 days with three different sludge retention time (SRT). The pilot plant reactor was provided of funnel shape covers that guaranteed gas accumulation in the headspace. The results highlighted that N2O concentrations significantly increased when the biofilm concentrations increased within the aerobic and anoxic compartments. Furthermore, results have shown an increase of N2O with the decrease of SRT. Moreover, the MBR tank resulted the key emission source (up to 70% of the total N2O …
Aeration tank and secondary clarifier as one system. in "Activated Sludge Separation Problems: Theory, Control Measures, Practical Experieces. Eds. R…
2017
Traditionally the activated sludge process is treated as two stage process. The first stage (aeration basin) is described in terms of biological processes while the description of the second stage concentrates on processes of biomass separation and thickening. The modern approach to the activated sludge process looks at both the biological and the separation stage as one system. The aim of this chapter is to explain the interactions between the two parts of the activated sludge system.
The impact of in-canopy wind profile formulations on heat flux estimation in an open orchard using the remote sensing-based two-source model
2010
Abstract. For open orchard and vineyard canopies containing significant fractions of exposed soil (>50%), typical of Mediterranean agricultural regions, the energy balance of the vegetation elements is strongly influenced by heat exchange with the bare soil/substrate. For these agricultural systems a "two-source" approach, where radiation and turbulent exchange between the soil and canopy elements are explicitly modelled, appears to be the only suitable methodology for reliably assessing energy fluxes. In strongly clumped canopies, the effective wind speed profile inside and below the canopy layer can strongly influence the partitioning of energy fluxes between the soil and vegetation co…

Development and validation of the Short Professional Quality of Life Scale based on versions IV and V of the Professional Quality of Life Scale
2020
Background This research presents a short version of the Professional Quality of Life (ProQOL) scale, one of the most frequently used questionnaires in the arena of applied healthcare investigation. It measures burnout (BO), compassion fatigue (CF), and compassion satisfaction (CS). Methods A 9-item version of the ProQOL was developed. In Study 1, this short version, which used items from version IV of the ProQOL, was administered to 817 palliative care professionals from Spain, Argentina, and Brazil. In Study 2, the same nine items, but this time from version V of the ProQOL, were administered to 296 Spanish palliative care professionals. Results Study 1: The Short ProQOL showed an adequat…
Variation in human water turnover associated with environmental and lifestyle factors
2022
Water is essential for survival, but one in three individuals worldwide (2.2 billion people) lacks access to safe drinking water. Water intake requirements largely reflect water turnover (WT), the water used by the body each day. We investigated the determinants of human WT in 5604 people from the ages of 8 days to 96 years from 23 countries using isotope-tracking ( 2 H) methods. Age, body size, and composition were significantly associated with WT, as were physical activity, athletic status, pregnancy, socioeconomic status, and environmental characteristics (latitude, altitude, air temperature, and humidity). People who lived in countries with a low human development index (HDI) had highe…
High Cryptosporidium prevalences in healthy Aymara children from the northern Bolivian Altiplano.
1998
The prevalence of Cryptosporidium infection was determined in four Aymara communities in the Bolivian Altiplano, between the city of La Paz and Lake Titicaca, at an altitude of 3,800-4,200 meters. Single stool specimens were randomly collected from 377 5-19-year-old students, all apparently asymptomatic. The total prevalence (31.6%) is possibly the highest reported among healthy humans (a maximum of 9.8% and 2.0% in coprologic surveys in underdeveloped and developed countries, respectively) and one of the highest even in symptomatic subjects. No significant age and sex differences were observed. Such an infection prevalence is probably related to the poor sanitation conditions, contaminated…
