Proton-Hydrogen Charge Exchange and Elastic Scattering in the Faddeev Approach
2000
Results of the application of Faddeev-type integral equations to proton-hydrogen collisions are reported. The approach, realized in the impact parameter representation, incorporates the exact two-particle off-shell Coulomb T-matrices in all ‘triangle’ contributions to the effective potentials. Calculatedtotal and differential electron-transfer as well as differential elastic scattering cross sections show very good agreement with experiment, over a wide range of incident energies.
Deregulated Electric Energy Price Forecasting in NordPool Market using Regression Techniques
2019
Deregulated electricity market day-ahead electrical energy price forecasting is important. It is influenced by external parameters and it is a complicated function. In this work two neighboring regions in the NordPool market are analyzed to provide day-ahead electrical price forecasting using regression techniques. The characteristics of the NordPool market trading behavior leads to unanticipated price peaks at daily, weekly and annual level. The considered two Nordic regions have different energy generation sources (e.g Norway has controllable hydro power, Denmark has non-controllable wind-power) therefore day-ahead electrical energy price forecasting in deregulated market for these two ne…
Quality management in the public sector accounting department - (un)avoidable quality costs and unlikely financial impacts
2017
This paper investigates the nature of quality costs and the likelihood of their having financial impacts in the public sector. An illustrative quality development case project in an accounting department of a Finnish city administration is presented. The empirical data includes answers to a qualitative project question sheet, workshop material and participative observation. Quality problems are classified according to their quality cost category and the extent to which they are avoidable. Some of the quality costs proved unavoidable and some are likely to lack financial impact, exhibiting sticky cost behaviour. The study indicates that certain prevention and appraisal costs in the public se…
Resultado económico y de empleo en las organizaciones sociales de origen familiar
2018
La Unión Europea ha apostado por el modelo de empresa social como una herramienta para corregir los desequilibrios socioeconómicos en los países miembros. En el contexto de la economía española, las organizaciones familiares destacan debido a su fuerte presencia y apoyo. El objetivo de este trabajo es estudiar la relación entre el rendimiento económico y el nivel de empleo, como indicador de impacto social, en las organizaciones aragonesas de origen familiar, así como las diferencias en esta interacción cuando la forma lucrativa o no lucrativa de la estructura formada por la unidad familiar se introduce como variable moderadora. Para ello, se obtuvo una muestra de 2.931 empresas y 117 funda…
Work incapacity among family caregivers : a record linkage study
2022
BackgroundFamily caregiving-related physical and mental health problems may lead to work incapacity in employed caregivers. The aim of this study was to quantify sickness absences and disability pensions (SADP) among high-intensity family caregivers available to the labour market compared with a control population.MethodsThe study sample included all individuals in Finland, who had received caregiver’s allowance and were available to the labour market in 2012 (n=16 982) and their controls (n=35 371). Information on the number of sickness absence (spells >10 days) and disability pension (SADP) days and related diagnoses according to ICD-10 were obtained from national registers for the yea…
Las empresas sociales: un grupo en expansión en el ámbito de la Economía Social. Identificación y análisis de las características identitarias de la …
2015
Durante los últimos veinte años la empresa social está conociendo una notable expansión en la Unión Europea acompañada de una proliferación de conceptos y términos que tratan de definirla y diferenciarla de las empresas tradicionales, —tanto del sector público y privado como de la Economía Social—así como de un aumento significativo del interés en la medición de su impacto. La Tesis se propone, en primer lugar, recopilar y analizar los principales enfoques, dimensiones y definiciones existentes en torno al concepto de empresa social en el ámbito científico, así como los marcos conceptuales y escenarios legales presentes en los países de la Unión Europea, con el objetivo de proponer un conju…
Translated and adaptation into Persian of the podiatric health questionnaire (PHQ)
2023
[Abstract] The Podiatric Health Questionnaire (PHQ) is a foot health psicometric tool consisting of six items for measuring foot health status. Currently, PHQ has been adapted into Spanish. Thus, this research focused on develop the Persian translation and adaptation of the PHQ. The translation into Persian and test-retest reliability methods were applied from english version questionnarie. As regards to the total mark for each sub-scale, internal consistency and reliability were determined by the Cronbach α and intraclass correlation coefficient (ICC) with a confidence interval (CI) of 95%. High internal consistency was shown for the six sub-scales: a) walk with a Cronbach α of 0.775; b) h…
Spanish Secondary School Students' Notions on the Causes and Consequences of Climate Change
2010
This paper is part of an extensive study of secondary school students' preconceived ideas about climate change. Here, we undertake a survey in the province of Valencia (Spain) to ascertain secondary school students' notions of the causes and consequences of climate change. Results show, among other things, that students clearly relate the misuse of motor vehicles and factory emissions to the problem. However, the obvious correlation with household energy use is not observed. The usual confusion with other environmental problems, such as the hole in the ozone layer, as described in previous studies, is also detected. Students know almost no greenhouse gases other than CO2, while the socio‐ec…
Characterization of the Etna volcanic emissions through an active biomonitoring technique (moss-bags): Part 2 – Morphological and mineralogical featu…
2013
Volcanic emissions were studied at Mount Etna (Italy) by using moss-bags technique. Mosses were exposed around the volcano at different distances from the active vents to evaluate the impact of volcanic emissions in the atmosphere. Morphology and mineralogy of volcanic particulate intercepted by mosses were investigated using scanning electron microscopy (SEM) equipped with energy dispersive spectrometer (EDS). Particles emitted during passive degassing activity from the two active vents, Bocca Nuova and North East Crater (BNC and NEC), were identified as silicates, sulfates and halide compounds. In addition to volcanic particles, we found evidences also of geogenic, anthropogenic and marin…
The Role of re-design for Additive Manufacturing on the Process Environmental Performance
2018
Abstract At present, economic and technological design criteria for products and processes should be matched with the minimization of environmental impact objectives. Manufacturing, material production, and product design are strictly connected stages. The choice of a production system over another could result in significant material and energy/resource savings, particularly if the component has been properly designed for manufacturing. In this scenario, Additive Manufacturing, which has been identified as a potential disruptive technology, gained an increasing interest for the creation of complex metal parts. The paper focuses on the tools, based on the holistic modelling of additive and …
