Characterization of a LIG-based parallel-plate supercapacitor

Treballs Finals de Grau de Física, Facultat de Física, Universitat de Barcelona, Curs: 2022, Tutors: Roger Amade Rovira, Stefanos ChaitoglouSeveral samples of graphene-based electrodes were fabricated by laser-irradiation. Laser power and scanning speed were optimized, in order to favor the formation of nanostructured LIG electrodes. The analysis is performed by SEM, Raman spectroscopy, cyclic voltammetry and galvanostatic charge-discharge. With these optimized parameters, a parallel-plate supercapacitor is built and specific capacitance measurements are performed. Values up to (48 ± 3)mF/cm−2 for the sqared samples and (2, 72 ± 0.13) mF/cm−2 for the supercapacitor device were obtaine

Integrated methodology for assessing the effects of geomorphological river restoration on fish habitat and riparian vegetation

Changes in the geomorphology of rivers have serious repercussions, causing losses in the dynamics and naturalness of their forms, going in many cases, from a type of meandering channel, with constant erosion and sedimentation processes, to a channelized narrow river with rigid and stable margins, where the only possibility of movement occurs in the vertical, causing the only changes in channel geometry occur in the river bed. On the other hand, these changes seriously affect the naturalness of the banks, preventing the development of riparian vegetation and reducing the cross connectivity of the riparian corridor. Common canalizations and disconnections of meanders increase the slope, and therefore speed, resulting in processes of regressive erosion, effect increased as a result of the narrowing of the channel and the concentration of flows. This process of incision may turn the flood plain to be "hung", being completely disconnected from the water table, with important consequences for vegetation. As an example of the effects of these changes, it has been chosen the case of the Arga River The Arga river has been channelized and rectified, as it passes along the meander RamalHondo and Soto Gil (Funes, Navarra). The effects on fish habitat and riparian vegetation by remeandering the Arga River are presented. and Ttwo very contrasting situationsrestoration hypothesis, in terms of geomorphology concerns, have been established to assess the effects these changes have on the habitat of one of the major fish species in the area (Luciobabus graellsii) and on the riparian vegetation. To accomplish this goal, it has been necessary to used the a digital elevation model provided by LIDAR flight, bathymetric data, flow data, as inputs, and a hydraulic simulation model 2D (Infoworks RS). The results obtained not only helped to evaluate the effects of the past alterations of geomorphologic characteristics, but also to predict fish and vegetation habitat responses to this type of changes

LAS PROVINCIAS MALACOLÓGICAS MIOCENAS Y RECIENTES DEL ATLÁNTICO SUDOCCIDENTAL

Southwestern Atlantic Recent and Miocene Malacological Provinces are recognized as properly delimited, according to Jaccard and Simpson association coefficients. The Recent Argentinean Province is considered a Provincetone between the Magellanic and the Brazilian Provinces, and one of its principal characteristics is the presence of magellanic elements most probably coming from the Southeastern Pacific. Its development happened after the Antarctic Circumpolar Current fully began to operate, originating the cold Malvinas (Falkland) Current. The Argentinean Province is not the geographic/temporal continuity of the molluscan assemblages that lived during Late Miocene times in the region. Instead, these latter associations constituted the Miocene Valdesian and Paranaian Provinces, mostly integrated by Caribbean elements. When these biogeographic units desintegrated because of the cooling of surface waters caused by the implantation of the Malvinas Current, the tropical elements did not stay in the high latitudes of the Western Atlantic Ocean, but moved back northwards where are restricted today or became extinct.Las Provincias Malacológicas Miocenas y actuales del Atlántico Sudoccidental están bien delimitadas de acuerdo con los coeficientes de asociación de Jaccard y de Simpson. La actual Provincia Argentina es considerada un Provinciatono (sensu Petuch 1988) entre la Magallánica y la Brasileña, y una de sus principales características es la presencia de elementos magallánicos, muy probablemente originados en el Sudeste del Océano Pacífico. Se propone como hipótesis que su presencia en el área comenzó a partir del desarrollo de la Corriente fría de Malvinas (Falkland), una vez establecida definitivamente la Corriente Circumpolar Antártica. La Provincia Argentina no representa una continuidad espacio-temporal de las asociaciones de moluscos que vivían en el Mioceno Tardío en la región. En esos tiempos, se encontraban establecidas las Provincias Valdesiana y Paraniana, integradas fundamentalmente por elementos caribeños. Cuando estas unidades biogeográficas se desintegraron a causa del enfriamiento de las aguas provocado por la formación de la Corriente de Malvinas, los elementos tropicales retrajeron su distribución muy hacia el norte, donde aún hoy existen algunos representantes, o se extinguieron

The utility of the MMPI-2-RF to predict the outcome of a smoking-cessation treatment

People with psychopathology experience high rates of smoking and have more trouble quitting. The Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF; Tellegen & Ben-Porath, 2008, 2009) is a valid and reliable instrument for the assessment of psychopathology. In this study, we examined the ability of the MMPI-2-RF to assess psychopathology and to predict smoking cessation outcomes in a sample of 281 smokers seeking psychological treatment to stop smoking at the end of treatment and at 6- and 12-month follow-ups. Results showed that T-scores < 65 on Disaffiliativeness (DSF) scale were associated with a higher likelihood of smoking at the end of treatment, and T-scores = 65 on Neurological Complaints (NUC) scale were associated with a higher likelihood of smoking at the 12-month follow-up, after controlling for the effect of age and initial levels of nicotine dependence. The results highlight the usefulness of the MMPI-2-RF in the field of smoking cessation treatment

Linked open data to represent multilingual poetry collections : A proposal to solve interoperability issues between poetic repertoires

This paper describes the creation of a poetic ontology in order to use it as a basis to link different databases and projects working on metrics and poetry. It has been built on the model of the Spanish digital repertoire ReMetCa, but its aim is to be enlarged and improved in order to fit under every poetic system. The conceptual semantic model, written in OWL, includes classes and metadata from standard ontological models related to humanities fields (such as CIDOC or Dublin Core), and adds specific elements and properties to describe poetic phenomena. Its final objective is to interconnect, reuse and locate data disseminated through poetic repertoires, in order to boost interoperability among them.Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET

National Strategy for River Restoration in Spain: A multidisciplinary approach.

A National Strategy for River Restoration is being implemented by the Spanish Ministry of Environmental Affairs, with the scientific assistance of the Universidad Politécnica of Madrid. Theoretical concepts from Fluvial Geomorphology and Ecology, together with Water Framework Directive principles and objectives, have been the basis for this Strategy, whose the main objective is to improve the ecological status of rivers, recovering their natural variability and dynamics

Gender differences in personality patterns and smoking status after a smoking cessation treatment

Background: The lack of conclusive results and the scarce use of the Millon Clinical Multiaxial Inventory-III (MCMI-III) in the study of the relationship between smoking and personality are the reasons that motivated the study reported here. The aim of the present study was to analyze the influence of personality patterns, assessed with the MCMI-III, and of nicotine dependence on treatment outcomes at the end of the treatment and at 12 months follow-up in men and women smokers receiving cognitive-behavioral treatment for smoking cessation. Methods: The sample was made up of 288 smokers who received cognitive-behavioral treatment for smoking cessation. Personality patterns were assessed with the Millon Clinical Multiaxial Inventory-III (MCMI-III). Abstinence at the end of the treatment and at 12-month follow-up was validated with the test for carbon monoxide in expired air. Results: The results showed significant differences by personality patterns that predict nicotine dependence (Narcissistic and Antisocial in men and Schizoid in women). At the end of the treatment it is more likely that quit smoking males with a Compulsive pattern and less likely in those scoring high in Depressive, Antisocial, Sadistic, Negativistic, Masochistic, Schizotypal and Borderline. In women, it is less likely that quit smoking those with the Schizoid pattern. At 12 months follow-up it is more likely that continue abstinent those males with a high score in the Compulsive pattern. Furthermore, nicotine dependence was an important variable for predicting outcome at the end of the treatment and smoking status at 12 months follow-up in both men and women. Conclusions: We found substantial differences by gender in some personality patterns in a sample of smokers who received cognitive-behavioral treatment for smoking cessation. We should consider the existence of different personality patterns in men and women who seek treatment for smoking cessation

On the Outer-Independent Roman Domination in Graphs

[EN] Let G be a graph with no isolated vertex and f:V(G)->{0,1,2} a function. Let V-i={v is an element of V(G):f(v)=i} for every i is an element of{0,1,2}. The function f is an outer-independent Roman dominating function on G if V0 is an independent set and every vertex in V-0 is adjacent to at least one vertex in V-2. The minimum weight omega(f)= Sigma v is an element of V(G)f(v) among all outer-independent Roman dominating functions f on G is the outer-independent Roman domination number of G. This paper is devoted to the study of the outer-independent Roman domination number of a graph, and it is a contribution to the special issue "Theoretical Computer Science and Discrete Mathematics" of Symmetry. In particular, we obtain new tight bounds for this parameter, and some of them improve some well-known results. We also provide closed formulas for the outer-independent Roman domination number of rooted product graphs.Cabrera Martínez, A.; Cabrera García, S.; Carrión García, A.; Grisales Del Rio, AM. (2020).

Effects of Trophic Level and Metamorphosis on Discrimination of Hydrogen Isotopes in a Plant-Herbivore System

The use of stable isotopes in ecological studies requires that we know the magnitude of discrimination factors between consumer and element sources. The causes of variation in discrimination factors for carbon and nitrogen have been relatively well studied. In contrast, the discrimination factors for hydrogen have rarely been measured. We grew cabbage looper caterpillars (Trichoplusia ni) on cabbage (Brassica oleracea) plants irrigated with four treatments of deuterium-enriched water (δD = −131, −88, −48, and −2‰, respectively), allowing some of them to reach adulthood as moths. Tissue δD values of plants, caterpillars, and moths were linearly correlated with the isotopic composition of irrigation water. However, the slope of these relationships was less than 1, and hence, discrimination factors depended on the δD value of irrigation water. We hypothesize that this dependence is an artifact of growing plants in an environment with a common atmospheric δD value. Both caterpillars and moths were significantly enriched in deuterium relative to plants by ∼45‰ and 23‰ respectively, but the moths had lower tissue to plant discrimination factors than did the caterpillars. If the trophic enrichment documented here is universal, δD values must be accounted for in geographic assignment studies. The isotopic value of carbon was transferred more or less faithfully across trophic levels, but δ15N values increased from plants to insects and we observed significant non-trophic 15N enrichment in the metamorphosis from larvae to adult
