Chapter 8: EPR in glass ceramics

2019

The development of novel materials requires a profound understanding of the relationship between a material's performance and its structural properties. Electron paramagnetic resonance (EPR) is a well-established technique for a direct detection and identification of paramagnetic defects in solids. This chapter provides an overview of the applicability of continuous wave EPR spectroscopy in the studies of glass ceramics focusing on transition metal (Mn2 +, Cu2 +, Cr3 +) and rare earth (Gd3 +, Eu2 +, Er3 +, Yb3 +) ion local structure analysis. EPR spectra features of the above-mentioned paramagnetic probes in glasses and glass ceramics are compared and discussed in detail. The chapter also s…

Setting standards and implementing quality improvement in trauma care

1996

Setting standards and implementing quality improvement in trauma care needs consideration of the definitions of standards, guidelines, recommendations and the present quality of trauma care. Essential factors for consideration are the chain of survival and different intervals which may decide on patient outcome: (a) the trauma (occurrence) to trauma recognition interval which has, until now, not been taken into consideration with regard to morbidity and mortality; (b) the scene time is part of the total prehospital time which comprises rescuing the entrapped patient, preparation of the patient for treatment, and transfer to a rescue vehicle. The medical part of the scene time, however, repr…

Double-balloon enteroscopy-facilitated cyanoacrylate-injection endotherapy of small-bowel varices: an international experience from 2 European tertia…

2019

Background and Aims Small-bowel varices (SBVs) are an uncommon consequence of portal hypertension. Radiologic intervention is usually considered for first-line management. When radiologic intervention is not possible, management options become very limited. The aim of this study was to evaluate the usefulness of double-balloon enteroscopy (DBE)-facilitated cyanoacrylate-injection endotherapy of SBVs. Methods This was a retrospective review of DBE-facilitated cyanoacrylate-injection endotherapy of SBVs (December 2015 to October 2016). Results Ten DBEs were performed in 6 patients (4 women; median age, 68.5 years). No radiologic or surgical options were deemed feasible. Thirteen nests of SBVs…

El management de las conductas socioemocionales. Una aproximación teórica y empírica desde el caso de los agentes de "contact centers"

2020

How is a specific type of emotion-related work conducts formed today? What principles guide these conducts and what effects do they have on those who work? The study of Contact Center agents allows us to understand how a set of personal qualities such as patience and good treatment of others, certain desires and personal impulses or even intimate sensations such as anguish or individual expectations have become managerialized emotions that end up modifying the inner attitudes of these agents. Within this framework, we propose a theoretical approach that integrates the work of Weber, Foucault and Elias, which invites us to reflect on a socio-emotional manner of leading one?s life (Lebensfu?h…

Compensatory education: Long-term effects of early parental implication (and III: The C.P.C.)

2007

After describing the program of early compensatory education (from age 3 to 9), called Chicago Child-Parent Centers (CPC), this article collects and analyses the evaluation studies of that Program from a longitudinal perspective – Chicago Longitudinal Study (CLS)-, focusing primarily on methodological problems and afterwards on the short and, mainly, long terms effects, until the targeted subjects of the Program reached the age of 24. The studies confirm the Program has lasting educational (higher performance and educational achievements) and social (higher social adjustment) effects. Subsequently, it analyses which elements of the Program can produce these beneficial effects, which are bas…

Intra-urban spatial distributions of population and employment : the case of the agglomeration of Dijon, 1999

2003

The aim of this paper is to analyze the intra-urban spatial distributions of population and employment in the agglomeration of Dijon (regional capital of Burgundy, France). We study whether this agglomeration has followed the general tendency of job decentralization observed in most urban areas or whether it is still characterized by a monocentric pattern. In that purpose, we use a sample of 136 observations at the communal and at the IRIS (infra-urban statistical area) levels with 1999 census data and the employment database SIRENE (INSEE). First; we study the spatial pattern of total employment and employment density using exploratory spatial data analysis. Apart from the CBD, few IRIS ar…

Growth of paramagnetic defects by gamma rays irradiation in oxygen-deficient silica

2005

Abstract We report an electron paramagnetic resonance (EPR) study of gamma rays irradiation effects on an oxygen-deficient silica obtained from fused quartz. We have found that three types of E′ centers, E α ′ , E γ ′ and E δ ′ , and a paramagnetic defect in a spin triplet state (S = 1) are induced. The EPR signals dependence on the microwave power have been investigated. The concentrations of these centers as a function of gamma ray irradiation show that for high dose a limit value is reached suggesting a generation process from precursors.
