Evolución de episodios pluviométricos en la Demarcación Hidrográfica del Júcar (1989-2016): del recurso al riesgo
2020
Este trabajo aborda la clasificación y evolución diacrónica de los episodios de lluvia (1989-2016) en ambientes mediterráneos, en la Demarcación Hidrográfica del Júcar. En base a datos del SAIH, y siguiendo criterios hidrológicos, se seleccionan 698 episodios, que se caracterizan con indicadores de precipitación acumulada, intensidad y persistencia. Mediante un análisis cluster se identifican tres tipologías (episodios de recurso limitado, de gran recurso a largo plazo y de riesgo) y se analiza su evolución temporal, estableciendo diferencias entre los episodios de interior y de litoral. Los resultados muestran una tendencia hacia el incremento del riesgo en detrimento del recurso en los tr…
Risk Analysis of a Fuel Storage Terminal Using HAZOP and FTA
2017
[EN] The size and complexity of industrial chemical plants, together with the nature of the products handled, means that an analysis and control of the risks involved is required. This paper presents a methodology for risk analysis in chemical and allied industries that is based on a combination of HAZard and OPerability analysis (HAZOP) and a quantitative analysis of the most relevant risks through the development of fault trees, fault tree analysis (FTA). Results from FTA allow prioritizing the preventive and corrective measures to minimize the probability of failure. An analysis of a case study is performed; it consists in the terminal for unloading chemical and petroleum products, and t…
The Impact of the Direct Participation of Workers on the Rates of Absenteeism in the Spanish Labor Environment.
2020
The aim of this research was to study the relationship between the different levels of direct participation of workers (passive, consultative or active-delegated) in risk prevention management with the levels of absenteeism in Spain. To this end, a transversal study was carried out using microdata from the Second European Survey of Companies on New and Emerging Risks (ESENER-2-Spain, 2014) with a master population of 3162 work centres. A multinomial logistic regression model was carried out, with the dependent variable being the levels of absenteeism and the independent variables, the participation indicators and preventive management, calculating the adjusted odds ratio (aOR) between all t…

'I had to help my child!': The role of emotions, risk, and trust in use of nasal decongestants in children.
2013
Recent studies suggest that a number of common cold medicines, including nasal decongestants are not suitable for small children. In Latvia nasal decongestants are primarily over-the-counter (OTC) medicines, and patient information leaflets generally permit use of these medicines for small children. The previous studies in Latvia investigating the use of medicines in cases of common cold demonstrated extensive use of decongestants in children less than six years of age, marking a necessity for more profound research. As a result a qualitative study was implemented in 2011 to identify sources of information that offer advice for the use of decongestants in children. The caregivers’ percepti…
The Stroke Riskometer (TM) App: Validation of a data collection tool and stroke risk predictor
2014
Background The greatest potential to reduce the burden of stroke is by primary prevention of first-ever stroke, which constitutes three quarters of all stroke. In addition to population-wide prevention strategies (the ‘mass’ approach), the ‘high risk’ approach aims to identify individuals at risk of stroke and to modify their risk factors, and risk, accordingly. Current methods of assessing and modifying stroke risk are difficult to access and implement by the general population, amongst whom most future strokes will arise. To help reduce the burden of stroke on individuals and the population a new app, the Stroke Riskometer™, has been developed. We aim to explore the validity of the app fo…
La diabetes mellitus y el riesgo cardiovascular. ¿Es necesario el tratamiento integral de la diabetes mellitus tipo 2 y los factores de riesgo cardio…
2010
ResumenLas enfermedades cardiovasculares (CV) son la primera causa de muerte en la población española, tanto en personas diabéticas como no diabéticas. En la diabetes, la enfermedad CV es entre 2 y 4 veces más frecuente, más precoz y más agresiva. Con las medidas actuales se puede llegar a una prevención del ∼50% de la enfermedad CV. Los factores de riesgo CV en la diabetes son la hipertensión arterial (HTA), la dislipemia, el tabaquismo, la obesidad y el sedentarismo. Más del 80% de pacientes con diabetes tipo 2 presenta HTA y dislipemia, y aproximadamente un 15% sigue fumando. Pero menos de un 10% tiene todos estos factores controlados. Aunque la dislipemia es el factor más condicionante …
Kombinētie darba vides riski pārtikas ķīmijas nozares laboratorijās, preventīvie pasākumi darba aizsardzībā

Izstrādātas praktiskās rekomendācijas darba vides riska pakāpes samazināšanai. Izmantotās metodes: Somijas 5 baļļu metode, Austrijas matrica ķīmisko risku novērtēšanai un darbinieku aptauja (v…
A root cause analysis method for preventing erratic behavior in software development: PEBA
2019
Measures taken to prevent faults from being introduced or going undetected can secure development of highly reliable software systems. One such measure is analyzing root causes of recurring faults and preventing them from appearing again. Previous methods developed for this purpose have been reactive in nature and relied heavily on fault reporting mechanisms of ogranizations. Additionally, previous efforts lack a defined mechanism for innovating corrective actions. In this study, we strive to complement the existing methods by introducing a proactive and qualitative method that does not rely on fault data. During the course of the research, in addition to an extensive literature search, an …
Root canal morphology and configuration of 123 maxillary second molars by means of micro-CT.
2017
The aim of this study was to investigate the root canal configuration, accessory canals and number of main foramina of 123 maxillary second molars by means of micro-computed tomography. The teeth were scanned and reproduced with 3D software imaging. The root canal configuration and number of main foramina were evaluated by means of a four-digit system. The morphological complexity of human maxillary second molars is depicted by the number of accessory and connecting canals. The most frequently observed root canal configurations in the mesiobuccal root were 2-2-2/2 (19.5%), 2-2-1/1 (14.6%) and 2-1-1/1 (13.0%). A 1-1-1/1 configuration was observed in 93.5% and in 96.7% in the distobuccal and …
