Sanitser, an innovative sanitary ware body, formulated with waste glass and recycled materials

Abstract In the present paper, the results of "Sanitser" Life European project are presented. The aim of this study was to reduce the firing temperature for ceramic body (from 1250 to 1170 °C). This was achieved substituting feldspar and quartz with recycled blend materials and a little percentage of flux (less than 3%); in a sanitary ware vitreous china formulation a waste glass, granitic materials and fired broken ceramic pieces were introduced. Tests performed on the Sanitser formulation showed that it has the same final physical-chemical characteristics of the industrial vitreous china (VC) body. Besides, different ceramic pieces (wash basin, bidet and WC pan) were compared with VC production. The results showed that Sanitser body can replace vitreous china in the sanitary ware production. In this project, the firing temperature of the ceramic body is reduced significantly with a supposed decrease of the CO2 emissions. In Sanitser formulation, about 43.6% of recycled materials that would end in dumps were utilized

Priming dilemmas’prisioners: an enquiry into agents’ minds

This work tries to understand how an exposure to economic logic and the current definition of rationality influences behavior. I usea randomized scrambled-sentencetestthat primes different groups either with economic or moral oriented key-words;then follows a set of ethicalgames, mainlyvariations of the Prisoner’s dilemma. In both an experimental setting (117economics/business graduates) and online survey (113 subjects), I do not findevidence that this short-term, conceptual priminghas an impact on agents’ decisions regarding this sort of dilemmas.This might be due to the ineffectiveness of the priming, or due to its subtle nature that only bigger datasets can uncover. However, it is found evidencein the online surveycorroborating the literature stance that having had an economics background alters behaviortowards defection. The evidence also highlights a particularly robust find in the literature: cooperation rates are far higher than expected by the self-interest model. These findings then open a more in depth discussion about thevery concept of rationality and theepistemological pathwithin economics

Effects of sintering temperature on microstructure and properties of sanitaryware ceramic produced with waste material

Abstract This paper aims at exploring the possibility of using a great percentage of recycled materials into vitreous china (VC), thus, contributing to urban waste decrease while lowering the industry's buying costs, previously optimized, for the sanitaryware production. The recycled blend was introduced in the ceramic slip, Sanitser VC, and used in three sanitaryware production plants. This slip let to improve the environmental performances of the overall ceramic production through energy-saving and a decrease in greenhouse gas emissions. In fact, the firing temperature is 80-100 °C lower than traditional production. Therefore, the objective of this paper was to evaluate the firing behavior, technological properties, and microstructure of a typical industrial vitreous china body in comparison with Sanitser VC. The analytical results confirmed the force of this idea and highlighted the advantages of the choice made

Diagnóstico e Tratamento de Doenças Lisossomais: relatório 2012

Relatório anual do Grupo de Trabalho Coordenador do Diagnóstico e Tratamento de Doenças Lisossomais (GTCDTDL), relativo ao ano 2012, do qual se destaca a realização das seguintes atividades: − Discussão e avaliação de 43 casos clínicos relativos a pedidos de tratamento, ajuste de dose ou alteração do tratamento, mais 16 casos do que em 2011. Foram emitidos pareceres para Doença de Gaucher, Doença de Fabry, Mucopolissacaridoses tipo I, II e VI, Doença de Pompe e Doença de Niemann Pick tipo C. − Prossecução da compilação da documentação relativa aos doentes com a finalidade de constituir uma base de dados. − Avaliação atualizada e envio regular dos encargos mensais por doença e entidade prestadora dos cuidados de saúde, bem como a data de início e/ou suspensão das terapêuticas à Administração Central do Sistema de Saúde (ACSS). − Consolidação da constituição do grupo de trabalho e formulação de convite a consultores científicos, quando pertinente. − Compilação de documentação científica e informação de entidades europeias. − Organização logística interna e externa e de documentos de suporte, existindo formulários de registo dos dados individuais para solicitação de início e seguimento da terapêutica. − Estabelecimento e fortalecimento de contactos com instituições ou organismos relevantes (INFARMED, ACSS, DGS), associações de doentes (ex: APL, Raríssimas, Eurordis) e a indústria farmacêutica (Genzyme, Actelion, Biomarin, Shire). Em 2012, o GTCDTDL prosseguindo a sua missão de garantir a gestão e a coordenação a nível nacional do diagnóstico e tratamento das DLS, constatou que, apesar do número de doentes em tratamento continuar a aumentar, a política seguida pelo Grupo de trabalho de procurar individualizar melhor a dose terapêutica em cada doente reduzindo-a sempre que possível, aliada à redução dos preços pela indústria farmacêutica, tem permitido alguma contenção dos custos

A relação entre a autodeterminação, a perspetiva temporal de futuro e o comportamento pro-ambiental

As alterações climáticas são consideradas atualmente como uma das maiores emergências que o planeta Terra enfrenta. Foi com esta preocupação em mente que surgiu o foco de estudo da presente dissertação, na tentativa de promover um melhor entendimento da motivação individual relativamente ao comportamento pró-ambiental e, possivelmente, da intervenção existente especifica na área da Psicologia. Desta forma, o estudo focou-se em observar a relação entre três variáveis do campo motivacional, a autodeterminação e a perspetiva temporal de futuro como preditoras do comportamento pró-ambiental, onde o principal objetivo do estudo foi o de observar correlações positivas entre variáveis de motivação intrínseca e da perspetiva temporal de futuro com variáveis do comportamento pró-ambiental. Para tal, foi elaborado um protocolo para a recolha de dados online, entre Janeiro e Abril de 2020, composto pelos três instrumentos de resposta correspondentes: Escala da Autodeterminação, o Inventário de Perspetiva Temporal de Futuro (IPT) e a escala de avaliação do Comportamento Pró-ambiental. Em geral, comprovando a literatura já existente e considerando apenas as três variáveis principais, conseguimos observar uma correlação positiva entre a autodeterminação e o comportamento pró-ambiental. Por outro lado, não se observou a mesma correlação positiva entre a perspetiva temporal de futuro e o comportamento pró-ambiental.Climate Change is considered, in the present days, as one of the biggest emergencies the planet Earth have been facing. The feeling of urgency towards this topic was the trigger to the present study while trying to promote a better understanding of the individual motivation connected with their pro-environmental behavior and possibly to a better understanding of specific intervention methods in Psychology field. Considering the stated, the present work focused on observing the relation between two variables of the motivational field, self-determination and future time perspective as predictors of the pro-environmental behavior, where the main goal was to observe positive correlations between self-determination variables and future time perspective with variables from pro-environmental behavior. To do so, a protocol for an online collection of the data was made. The collection occurred between January and April of 2020 and the protocol consisted of three instruments: Scale for Self-determination, Inventory of Future Time Perspective and a scale for the evaluation of pro-environmental behavior. In the end, together with the results observed in previous investigations and the correlations observed in the main variables, we were able to recognize a positive correlation between self-determination and pro-environmental behavior. On the other hand, it was not observed in our results a positive correlation between future time perspective and pro-environmental behavior

Tameness of holomorphic closure dimension in a semialgebraic set

Given a semianalytic set S in a complex space and a point p in S, there is a unique smallest complex-analytic germ at p which contains the germ of S, called the holomorphic closure of S at p. We show that if S is semialgebraic then its holomorphic closure is a Nash germ, for every p, and S admits a semialgebraic filtration by the holomorphic closure dimension. As a consequence, every semialgebraic subset of a complex vector space admits a semialgebraic stratification into CR manifolds satisfying a strong version of the condition of the frontier.Comment: Published versio
