Control térmico de la meteorización de superficies endurecidas en rocas graníticas (La Pedriza de Manzanares, España)

[ES] La Pedriza de Manzanares es parte del Parque Nacional del Guadarrama en el Sistema Central Español. Se caracteriza por formar un paisaje laberíntico constituido por una alternancia de bloques y grandes paredes de granito. Gran parte de las superficies de estas rocas están recubiertas por costras endurecidas de espesores milimétricos, que controlan la alteración superficial y favorecen el desarrollo y distribución de micro-relieves sobre las paredes. Para explicar el proceso de alteración que favorece la formación de irregularidades sobre la superficie del granito, en este trabajo se analizan algunas variables tales como la temperatura, índice de esclerometría y morfología de los micro-relieves. Por otra parte, el artículo establece relaciones entre la primera fase de formación de las superficies endurecidas en condiciones subedáficas, asociada al frente de alteración, con los espesores de las costras endurecidas y la erosión del regolito. Las relaciones definidas y resultados obtenidos son de aplicación en otras regiones graníticas del mundo de características similares.[EN] Pedriza de Manzanares is part of the Guadarrama National Park in the Spanish Central System. It is characterized by a labyrinthine landscape composed of alternating blocks and large walls of granite. Case-hardened crusts of millimetric thickness covering most of these rock surfaces control the surface alteration and favor the development and distribution of micro-reliefs on the walls. Some variables such as temperature, sclerometric index and micro-relief morphology are analyzed in this paper in order to explain the destructive process of alteration that favors the formation of irregularities on the granite surface. On the other hand, the paper establishes the relation between the first stage of case-hardening in sub-edaphic conditions, which is associated with the alteration front, and the thickness of such crusts and regolith erosion. These results can be applied to other granitic regions with similar characteristics all over the world.Peer reviewe

Finally, the authors also are thankful to “Neoliquid Advanced Biofuels and Biochemicals S.L.” for providing the industrial chars from municipal solid waste, “Grupo Layna Gestión de Residuos S.L.” for providing the industrial char from biomass waste, and “Ecocuadrado S.L.” for providing municipal and industrial solid waste. Funding for open access charge: Universidad de Granada/CBUA.Pyrolysis of residues enriched with carbon, such as in agroforestry or industrial activities, has been postulated as an emerging technology to promote the production of biofuels, contributing to the circular economy and minimizing waste. However, during the pyrolysis processes a solid fraction residue is generated. This work aims to study the viability of these chars to develop porous carbonaceous materials that can be used for environmental applications. Diverse chars discharged by an industrial pyrolysis factory have been activated with KOH. Concretely, the char residues came from the pyrolysis of olive stone, pine, and acacia splinters, spent residues fuel, and cellulose artificial casings. The changes in the textural, structural, and composition characteristics after the activation process were studied by N2 adsorption-desorption isotherms, scanning electron microscopy, FTIR, elemental analysis, and XPS. A great porosity was developed, SBET within 776–1186 m2 g−1 and pore volume of 0.37–0.59 cm3 g−1 with 70–90% of micropores contribution. The activated chars were used for the adsorption of CO2, leading to CO2 maximum uptakes of 90–130 mg g−1. There was a good correlation between the CO2 uptake with microporosity and oxygenated surface groups of the activated chars. Moreover, their ability to adsorption of contaminants in aqueous solution was also evaluated. Concretely, there was studied the adsorption of aqueous heavy metals, i.e., Cd, Cu, Ni, Pb, and Zn, and organic pollutants of emerging concern such as caffeine, diclofenac, and acetaminophen.MICIU/AEI/10.13039/501100011033 CPP 2021-008551ERDF/EUEuropean Union NextGenerationEU/PRTRUniversity of GranadaUniversidad de Granada/CBU

Caracterización y degradación de los materiales graníticos de la Colegiata de San Isidro, Madrid, España

Original granitoids from the façade of the Colegiata de San Isidro are medium-grained-biotitic adamellites, from quarries of the Valdemorillo area (Madrid). The petrophysical properties of the materials allow to establish a clear difference between the two original granites: the most abundant one (A), with a lower porosity, lower water sorption capacity, a lower water vapour permeability coefficient, a higher ultrasonic waves transmission velocity, and a higher strength, respect to the least abundant granite (B). So it can be said the former is more resistant and of better quality than B-granite, or in other words, is a less-alterable granite than B-granite. In relation to the granites alteration trend, data make possible to establish that A-granite suffers less alteration than B-granite, because in the latter, values of the properties determined in internal and external sections, vary much more than for the A-granite. A brief reference to the conservation state of the main façade and to the monitoring of the atmospheric pollutants registered by two stations close to the building, with the aim of determining its inluence on the material degradation, which mainly consists of soiling and blackenning

The phenotype, psychotype and genotype of bruxism

Abstract. Bruxism is a jaw muscle activity that involves physio-pathological, psycho-social, hereditary and genetic factors. The purpose of this study was to determine the associations between self-reported bruxism, anxiety, and neuroticism personality trait with the rs6313 polymorphism in the gene HTR2A. A sample of 171 subjects of both sexes (14-53 years of age) was included. The control group (group 1, n=60) exhibited no signs or symptoms of bruxism. The case group had signs and symptoms of bruxism (n=112) and was subdivided into group 2, bruxism during sleep (n=22); group 3, awake bruxism (n=44); and group 4 combined bruxism (n=46). As diagnostic tools, the Self-Reported Bruxism Questionnaire (SBQ), the Beck Anxiety Inventory (BAI) and the Eysenck Personality Questionnaire Revised-Abbreviated (EPQR-A) were used. HTR2A (rs6313) SNPs were determined by qPCR for all the participants. The packages SPSS, maxLik and EPI-INFO were used for data analysis. The combined bruxism group reported higher scores in bruxism symptoms, mean = 32.21; anxiety symptoms, mean = 14.80; and neuroticism, mean = 3.26. Combined bruxism was associated with a higher degree of neuroticism (OR=15.0; CI 1.52-148.32) and anxiety in grade 3-moderate (OR=3.56; CI 1.27-10.03), and grade 4-severe (OR=8.40; CI 1.45-48.61), as determined using EPISODE computer software. Genotypic homogeneity analysis revealed no significant differences in allele frequency (P=0.612) among the four groups. The population was in Hardy-Weinberg equilibrium (maxLik package). In conclusion, the three instruments confirm traits of bruxism, anxiety and neuroticism in individuals with bruxism. These data were ratified when the sample was divided by genotypic homogeneity. On the other hand, there was no significant difference between the groups in the SNPs rs6313 from the HTR2A gene

Precision abundance analysis of bright HII galaxies

We present high signal-to-noise spectrophotometric observations of seven luminous HII galaxies. The observations have been made with the use of a double-arm spectrograph which provides spectra with a wide wavelength coverage, from 3400 to 10400\AA free of second order effects, of exactly the same region of a given galaxy. These observations are analysed applying a methodology designed to obtain accurate elemental abundances of oxygen, sulphur, nitrogen, neon, argon and iron in the ionized gas. Four electron temperatures and one electron density are derived from the observed forbidden line ratios using the five-level atom approximation. For our best objects errors of 1% in t_e([OIII]), 3% in t_e([OII]) and 5% in t_e([SIII]) are achieved with a resulting accuracy of 7% in total oxygen abundances, O/H. The ionisation structure of the nebulae can be mapped by the theoretical oxygen and sulphur ionic ratios, on the one side, and the corresponding observed emission line ratios, on the other -- the \eta and \eta' plots --. The combination of both is shown to provide a means to test photo-ionisation model sequences currently applied to derive elemental abundances in HII galaxies.Comment: 24 pages, 8 figures, accepted by MNRA

Telemedicine, Psychology and Diabetes: Evaluation of results and cost analysis

The Psychosocial Aspects of Diabetes (PSAD) Study Group is an official Study Group of the European Association for the Study of Diabetes (EASD).AIMS: Evidences of benefits of telemedicine in T1DM patients on continuous subcutaneous insulin infusion (CSII) treatment are limited. Aims: 1) to analyse the differences in clinical and psychological variables between subjects with T1DM on CSII treatment who were included in a Telecare (TC) program, and subjects with T1DM on CSII treatment who received Conventional care (CC); 2) Perform a cost analysis of the use of telemedicine in DM1 patients treated with CSII (TC versus CC). METHODS and PARTICIPANTS: Cross-over randomized clinical trial with duration of 18 months. 51 patients signed informed consent. Participants were randomly assigned to receive TC program or CC during 6 months, and after a 3 months wash-out period, patients changed to CC or to TC respectively. TC program included monthly visits using an Internet platform. CC comprised face-to-face visits every three months. Sociodemographic, clinical and psychological data was measured at the beginning and at the end of TC and CC. The direct and indirect costs were also measured. T Student was performed to assess differences between first and last visits in both groups (TC / CC). RESULTS: Patients with telemedicine at the end of treatment, have fewer hyperglycemia / week, less distress and greater adherence. Considering both direct and indirect costs, the cost per treatment (TC / CC) is similar. CONCLUSIONS: Telemedicine has significant implications for clinical and psychological variables and has the same cost (total) than the conventional treatment. Therefore, it can be a useful alternative for treatment of DM1 patients with CSII. However, studies with a larger sample size are needed.Universidad de Málaga.
