Microscratch testing method for systematic evaluation of the adhesion of atomic layer deposited thin films on silicon
2016
The scratch test method is widely used for adhesion evaluation of thin films and coatings. Usual critical load criteria designed for scratch testing of coatings were not applicable to thin atomic layer deposition (ALD) films on silicon wafers. Thus, the bases for critical load evaluation were established and the critical loads suitable for ALD coating adhesion evaluation on silicon wafers were determined in this paper as LCSi1, LCSi2, LCALD1, and LCALD2, representing the failure points of the silicon substrate and the coating delamination points of the ALD coating. The adhesion performance of the ALD Al2O3, TiO2, TiN, and TaCN+Ru coatings with a thickness range between 20 and 600 nm and dep…
De participació local. Una proposta metodològica desde la investigació-acció-participativa
2018
Citizen participation is an increasingly prevalent term in our society. In the process of deployment in the municipal area, progressively local corporations make efforts to innovate practices and develop experiences of citizen participation in defining policies and public affairs, and allocating budgets. While innovation has been advanced with regard to the tools and mechanisms to be used to promote participation, many of the initiatives and experiences have focused more on the implementation of the vote than in the different social processes inherent in the participation. Moreover, we are faced with the absence of a methodological guide that allows approaching a project or strategic plan o…
Aluminum tri-isopropoxide as an alternative precursor for atomic layer deposition of aluminum oxide thin films
2019
Due to the safety challenges associated with the use of trimethylaluminum as a metal precursor for the deposition of alumina, different chemicals have been investigated over the years to replace it. The authors have investigated the use of aluminum tri-isopropoxide (TIPA) as an alternative alkoxide precursor for the safe and cost-effective deposition of alumina. In this work, TIPA is used as a stable Al source for atomic layer deposition (ALD) of Al2O3 when different oxidizing agents including water, oxygen plasma, water plasma, and ozone are employed. The authors have explored the deposition of Al2O3 using TIPA in ALD systems operating in vacuum and atmospheric pressure conditions. For the…
The effect of inbreeding rate on fitness, inbreeding depression and heterosis over a range of inbreeding coefficients
2014
Understanding the effects of inbreeding and genetic drift within populations and hybridization between genetically differentiated populations is important for many basic and applied questions in ecology and evolutionary biology. The magnitudes and even the directions of these effects can be influenced by various factors, especially by the current and historical population size (i.e. inbreeding rate). Using Drosophila littoralis as a model species, we studied the effect of inbreeding rate over a range of inbreeding levels on (i) mean fitness of a population (relative to that of an outbred control population), (ii) within‐population inbreeding depression (reduction in fitness of offspring fro…
Paternal transition to parenthood: postpartum depression and parenting stress
2013
Background: Transition to parenthood is an important life event and a developmental crisis increasing vulnerability to psychological disorders. Postpartum depression and parenting distress are the most common psychological disturbances involving both mothers and fathers. This paper aims to explore maternal and paternal experience of transition to parenthood and compared them, to investigate the relationship between parenting distress and risk of postpartum depression, in mothers and fathers. Methods: one-hundred couples of parents were invited to compile the Edinburgh Postnatal Depression Scale and the Parenting Stress Index-Short Form in the first month of children life. The proposed resea…
The Occurrence of Diseases and Related Factors in a Center for Asylum Seekers in Italy
2016
Italy is the main recipient of asylum seekers in the European region, and Sicily is their first point of arrival. This geographical position creates a large job for Health Authorities to identify and deal with the health of immigrants. This study evaluates the prevalence of disease among asylum seekers, assessing which are associated factors.A cross-sectional study was conducted to analyse demographic and clinical data in an Acceptance Centres for Asylum Seekers from February 2012 to May 2013. All variables that were found to be significant on unvariable analysis for the most frequent pathologies were included in a multivariable logistic regression model.Post-traumatic stress disorders with…
Priekšstats par tēvu, stresa pārvarēšanas stratēģijas un depresijas simptomi pusaudžiem
2020
Šī maģistra darba mērķis bija izpētīt savstarpējas saistības starp priekšstatu par tēvu, stresa pārvarēšanas stratēģijam un depresijas simptomiem pusaudžiem; izpētīt, kādā mērā priekšstats par tēvu un stresa pārvarēšanas stratēģijas prognozē pusaudžu depresijas simptomus. Pētījumā piedalījās 200 pusaudži vecumā no 14 līdz 18 gadiem (M=16,0; SD = 1,21), no kuriem bija 56 zēni un 144 meitenes. Pētījuma dalībnieki aizpildīja Bērnu depresijas aptauju (Children Depression Inventory - CDI, Kovacs, 1979), Bērnu stresa pārvarēšanas (kopinga) stratēģiju aptauju (Children’s Coping Strategies Checklist -CCSC, Ayers & Sandler, 1999), Īpašību kategoriju sistēmu (izveidota maģistra darba ietvaros, balsto…
A Statistical Approach for A-Posteriori Deployment of Microclimate Sensors in Museums: A Case Study
2022
[EN] The deployment of sensors is the first issue encountered when microclimate monitoring is planned in spaces devoted to the conservation of artworks. Sometimes, the first decision regarding the position of sensors may not be suitable for characterising the microclimate close to climate sensitive artworks or should be revised in light of new circumstances. This paper fits into this context by proposing a rational approach for a posteriori deployment of microclimate sensors in museums where long-term temperature and relative humidity observations were available (here, the Rosenborg Castle, Copenhagen, Denmark). Different statistical tools such as box-and-whisker plots, principal component …
Sobre el reconocimiento del principio de dependencia, integridad y unidad del ecosistema terrestre por parte del estado y la persona humana
2021
La deliberación de una nueva Constitución Política para Chile, es una tremenda oportunidad de avanzar en una visión holística del derecho. Así las cosas, la grave crisis ecológica que hemos provocado como especie, y que desemboca en una crisis climatológica, nos obliga como sociedad a establecer un nuevo orden político y social donde se reconozca el que llamamos: “Principio de integridad y unidad del ecosistema terrestre”. ¿Pero de qué trataría este principio?. Este nuevo principio constitucional -propuesto-, supone superar la visión parcial del derecho, que ha separado históricamente los componentes del medio ambiente para tratarlos por separado -océanos, atmósfera, suelos, bosques, humeda…
Regional Disparities and Spatial Dependence of Bankruptcy in Spain
2021
Firm survival, bankruptcy, and turnaround are of great interest nowadays. Bankruptcy is the ultimate resource for a company to survive when it is affected by a severe decline. Thus, determinants of firm turnaround and survival in the context of bankruptcy are of interest to researchers, managers, and policy-makers. Prior turnaround literature has broadly studied firm-specific factors for turnaround success. However, location-specific factors remain relatively unstudied despite their increasing relevance. Thus, this paper aims to evaluate the existence of spatial dependence on the outcome of the bankruptcy procedure. Economic geography and business literature suggest that location matters an…
