On the existence of an upper critical dimension for systems within the KPZ universality class

In this work we extend the etching model to $d+1$ dimensions. This permits us to investigate its exponents behaviour on higher dimensions, to try to verify the existence of an upper critical dimension for the KPZ equations, with our results sugesting that $d=4$ is not an upper critical dimension for the etching model

Letters about difference. A matter of words (between friendship, discomfort and nonsense)

A través de un intercambio epistolar los autores de este texto se preguntan por algunas palabras de orden en los territorios de la filosofía de la educación: igualdad, diversidad, diferencia. La pregunta por aquello que nombra, pero sobre todo la pregunta por aquello que habita en el lenguaje, en la escritura y la lectura cuando nombramos, se hace presente en el artículo de un modo crudo, desnudo. La conversación aquí planteada es, también, una forma de comprender la conversación en la filosofía y la educación: palabras que buscan conmover, pero además hacer sentir y pensar lo Mismo y lo OtroThrough an exchange of letters the authors of this text ask for some words of order in the territories of the philosophy of education: equality, diversity, difference. The question of what names, but especially the question of what living in language, writing and reading when named, is present in the article in a raw, naked way. This count of conversation is also a way to understand the conversation in philosophy and education: words producing affect, but also trying to feel and think about the same and about the otherFil: Skliar, Carlos Bernardo.

Quando a Universidade era o Liceu: Sociedade, Política e Elites em Évora durante a I República

O presente estudo pretende contribuir para o conhecimento do meio social eborense no período da I Republica. O nosso intuito é colocar em destaque a acção pública das elites políticas e intelectuais cuja trajectória de vida as relacionou com a cidade e as suas instituições ao longo do período considerado. Embora a cronologia enunciada se inclua no logo interregno do ensino universitário em Évora, a nossa perspectiva analítica pretende dar relevo ao tópico da relação entre as instituições ligadas ao ensino, o Liceu em particular, e a dinâmica social e política da cidade. A prossecução deste objectivo desdobra-se nas seguintes etapas analíticas. Primeiro, efectua-se uma síntese sobre os traços essenciais da formação social no Sul de Portugal no período em estudo. Depois, procede-se a uma caracterização da cidade do ponto de vista do seu perfil de estratificação social e principais sectores de actividade económica. Em seguida, procuram captar-se as linhas de continuidade e/ou de ruptura em relação à composição social das mencionadas elites, quer em relação ao final da Monarquia Constitucional quer em relação ao início do Estado Novo. Finalmente, partindo do perfil biográfico de algumas das personalidades marcantes do período, reflecte-se sobre o significado de uma instituição como o Liceu para o processo de estruturação das elites políticas e diferenciação social em Évora

Soil properties and environmental risk assessment of soils in the surrounding area of Hulene‑B waste dump, Maputo (Mozambique)

Soils in areas surrounding landflls are constantly being enriched by heavy metals contained in the leachates, which can subsequently migrate to groundwater. The present investigation aims to characterize soil properties of 71 soil samples collected in the surroundings of Hulene-B waste dump and to determine the landfll pollution index (Ip). Soils properties studied were texture, pH, electrical conductivity, organic matter, color, and moisture. Results revealed that soils properties in the surroundings of Hulene-B waste dump were signifcantly altered when compared to local background. Ip index classifed these soils with very high pollution, indicating a possible migration of contaminants to subsoil and groundwater, suggesting the need for intervention to mitigate the impact.publishe

Soil risk assessment in the surrounding area of Hulene-B waste dump, Maputo (Mozambique)

Soil contamination in areas close to unplanned dumpsites represents an increasing risk to the ecosystems and human health. This study aimed to evaluate soil quality in the area surrounding the Hulene-B waste dump, Maputo, Mozambique, and to estimate potential ecological and human health risks. A total of 71 surface soil samples were collected in the surrounding area of the dump, along with 10 samples in areas considered not impacted by the dump. Chemical and mineralogical analyses were performed using XRF and XRD. Quartz was the most abundant mineral phase, followed by feldspars, carbonates, clay minerals, and Fe oxides/hydroxides. Results showed a significant contribution to ecological degradation by PTE enrichment, ranked as Zn >> Cu > Cr > Zr > Pb > Ni > Mn. Carcinogenic risk for both children and adults was significant due to Pb soil content. Soil sample concentrations of Cr, Cu, Mn, Ni, Pb, Zn, and Zr, posing a risk especially in children, suggested the need for continuous monitoring, as well as the definition and implementation of mitigation measures.publishe

Characterization of the dynamics of leachate contamination plumes in the surroundings of the Hulene‐B waste dump in Maputo, Mozambique

The contamination of areas around solid urban waste dumps is a global challenge for the maintenance of environmental quality in large urban centres in developing countries. This study applied a geophysical method (electrical resistivity) to identify leachate contamination plumes in the subsoil and groundwater, as well as to describe their temporal dynamics (2020 and 2021) in the surroundings of the Hulene‐B waste dump, Maputo, Mozambique. Eight 400 m electrical resistivity profiles were performed, four profiles in January 2020 and four profiles in May 2021 overlapped, and the data were inverted with RES2D software. The electrical resistivity models predominantly indicate an E‐W movement of large contamination plumes that are successively diluted with saturated media and groundwater, creating zones of less resistive anomalies (< 4.2–< 8.5 Ω∙m) possibly contaminated at the two analysed seasons, between 2020–2021. The thickness of the contamination plumes was higher in summer (2020) for profiles 1 and 2, and we associate it with the production and migration mechanisms of leachate that are intense in the hot and rainy season. Southwest of the dump, profile 4b showed the propagation of anomalous areas on the surface and at depth, which are associated with the production of leachate resulting from the continuous decomposition of waste that is continuously deposited in a new area southwest of the dump, thus generating a slow and continuous migration of leachate at depth, mainly in winter (2021). The spatial distribution of contamination plumes during both seasons was reduced significantly farther away from the waste deposit, revealing the attenuating effect of groundwater and lithological substrate (Profile 3).publishe
