Introduction to Immediate Loading in Implantology
2019
Branemark traditional recommendation was to perform implant rehabilitation in two stages: the first entry was only for implant placement; after 3–6 months of undisturbed submerged healing for mandible and maxilla, respectively, a second surgical entry would have allowed loading of the implants. The rationale behind this approach was that implant micro-movements as consequence by an inadequate primary stability, caused by functional forces at the bone-implant interface in the early wound healing stages, could have induced fibrous tissue formation rather than new bone, eventually causing clinical failure. The main request was to reduce the overall rehabilitation time from surgery to final res…
Characterization of activated sludge settling properties with a sludge collapse-acceleration stage
2019
Abstract The sedimentability of the activated sludge can be affected by the presence of a large variety of coagulants and polymers from a previous physical-chemical process. In this paper, the activated sludge settling process in industrial wastewater treatment plants where the sludge does not settle in a conventional way is studied. The two observed constant hindered settling velocity stages and the instant the intermediate sludge acceleration period occurs are described. A variation of the Richardson and Zaki model is used to characterize the two stages of constant settling velocity. The concentration of suspended solids, where a sudden decrease of hindered settling velocity was observed,…
To See More: A Model for Press Photograph Story Analysis
2013
AbstractThis article presents and evaluates an interdisciplinary model for press photograph story analysis. The research comprised two stages: (i) familiarizing study participants with the interpretation model and (ii) qualitative content analysis of the participants’ interpretations of samples of press photograph stories. The result is that the model could be used in the educational context to develop the skills of visual literacy among students. Although the study opens new directions in visual methodologies, the model requires further development.
Interactive Multiobjective Robust Optimization with NIMBUS
2018
In this paper, we introduce the MuRO-NIMBUS method for solving multiobjective optimization problems with uncertain parameters. The concept of set-based minmax robust Pareto optimality is utilized to tackle the uncertainty in the problems. We separate the solution process into two stages: the pre-decision making stage and the decision making stage. We consider the decision maker’s preferences in the nominal case, i.e., with the most typical or undisturbed values of the uncertain parameters. At the same time, the decision maker is informed about the objective function values in the worst case to support her/him to make an informed decision. To help the decision maker to understand the behavio…
José Luis Aranguren. Religión pensada, religión vivida
2015
In Aranguren’s work the religious dimension is crucial, when he deals with it from the point of view of the “religious studies” and also when he deals with it from the ethical perspective. In the second case Aranguren speaks about an “ethics open to religion”. The article tries to show that in the second case there is an evolution in Aranguren’s thought with two stages. In the first one, religion appears as the satisfaction of human aspirations, rooted in an ethics which is grounded in metaphysics. In the second one God appears as a possible answer to questions open from the perspective of a hermeneutic- narrative ethics.En la obra de Aranguren la dimensión religiosa es crucial, cuando la t…
TL-dating applied to building archaeology: The case of the medieval church Notre-Dame-Sous-Terre (Mont-Saint-Michel, France)
2007
Abstract The recent application of thermoluminescence (TL) dating to young building materials is being increasingly developed for use in the field of buildings archaeology [ Bailif, I.K., Holland, N., 2000.

Use of physicochemical processing in treating urban waste waters
1994
The principal objective of the present study was to compare two clearly defined purification processes in two stages: the periods 1985–1987 (conventional) and 1988–1990 (physico‐chemical). In general, the mean concentrations obtained were lower in the second period. A z‐test for comparing means was applied, but no significant correlation was observed (p ≤ 0.05). The mean concentrations obtained (with some exceptions) are lower in the second period. With the passing of time, the total volume of sewage flow has increased, and hence the load of contaminants has become diluted. The use of physico‐chemical treatment prior to biological processing may be the cause of the increase in cost.
Motivation and Mathematics Performance: A Longitudinal Study in Early Educational Stages
2017
Abstract This longitudinal study analyses the predictive value of a set of motivational variables on academic performance in the mathematics area. Analyses were performed on a sample of 180 children, with the data evaluated in two stages in formal educational settings (from kindergarten until 2nd year of Primary School). Likewise, differences between three groups (with low, average, and high mathematical performance at the end of second year of Primary School) in motivational and attributional variables assessed initially are also studied. The results show a significant predictive power on later mathematics achievement for self-perceived competence. Also persistence, attitude, and positive …
El mito quinqui. Memoria y represión de las culturas juveniles en la transición postfranquista
2020
Este trabajo parte de una imagen inicial–el cuarto quinqui como habitación histórica–para plantear el estudio del fenómeno quinquillero en una dialéctica compleja entre mitología, historicidad y memoria. Me planteo confrontar el actual regreso de lo quinqui en relación con las emergencias de los supuestos quinquis históricos en el archivo de los años setenta. Se trata, sin duda, de una confrontación problemática. Mi trabajo se organiza en dos tiempos. Primero, se trata de deconstruir “el mito quinqui”, analizando sus características y razones tanto en su construcción actual, como regreso quinqui, como en su emergencia histórica. Y después se trata de pensar qué es lo que ese mito impide ver…
A System of Indicators for Evaluating Public Broadcasting Corporations
2018
We describe an operational procedure to build an integrated information system (IIS) for monitoring and evaluating the performance of public broadcasting corporations (PBC). The procedure grounds in a conceptual framework derived from evaluation models, and consists of two stages. The first stage is the selection, through expert judgment, of simple indicators that illustrate the most relevant aspects of the corporations. The second stage is the definition of a system of indicators related to each level of the hierarchy of objectives planned by the corporations. The system of indicators has two levels. The first level is a basic indicator system that allows description and monitoring of the …
