"Ser sapo de este pozo". Desigualdades socioeducativas en el nivel secundario rural: aproximaciones de sentidos a las juventudes rurales; "A fish in the water". Socioeducational inequalities in rural high school: sense aproaches to rural youth Echegaray, María Carla El presente trabajo buscó visibilizar las desigualdades socioeducativas que se dan al interior del sistema educativo argentino, particularmente en el nivel secundario de la modalidad de educación rural. Se tomó como caso emblemático las escuelas secundarias “rurales aisladas” de la Provincia de San Juan en el Departamento 25 de Mayo; fundamentalmente por las particulares características que asume y, su ubicación en espacios periféricos completamente alejadas de las grandes ciudades. Se retomó una experiencia piloto de articulación entre el ciclo básico secundario rural aislado y ciclo orientado del nivel secundario, que permitió resignificar el discurso de los “jóvenes rurales” en torno al impacto de la educación secundaria en sus trayectorias. Esto además posibilitó realizar aproximaciones de sentidos y significaciones del “ser” joven rural en la construcción de esta nueva categoría analítica -“juventudes rurales”-.; The present work sought to visualize the socioeducational inequalities that occur within the Argentine educational system, particularly at the secondary level in the rural education modality. The isolated rural secondary schools of the province of San Juan in the department 25 de Mayo were taken as an emblematic case; fundamentally because of the particular characteristics that it assumes and, its location in peripheral spaces completely far from the big cities. A pilot experience of articulation between the isolated rural secondary basic cycle and the oriented cycle of the secondary level was resumed, which allowed resignifying the discourse of the rural youth around the impact of secondary education in their trajectories. This also made it possible to carry out approximations of meanings and meanings of the young rural being in the construction of this new analytical category -rural youth-.

Sliding mode neuro-adaptive controller designed in discrete time for mobile robots Rossomando, Francisco Guido; Soria, Carlos Miguel; Oliveira Freire, Eduardo; Carelli Albarracin, Ricardo Oscar It is well known that all robotic systems have additional dynamics and disturbances beyond those that are modelled. Hence, in this paper, the performance of a neuro-adaptive sliding mode control (NA-SMC) controller is analysed in the presence of disturbances and unmodelled dynamics. The proposed control strategy has two stages: first, a feedback linearization controller for a kinematic model; second, a neuro-adaptive SMC controller for a dynamic model. The entire control strategy is designed in discrete time using Lyapunov’s criterion, and the stability problems caused by direct implementation in discrete time to a system designed in a continuous domain are thereby avoided. The unmodelled dynamics introduce tracking errors in the closed-loop system; however, experiments made using the proposed approach to control mobile robots show that output tracking error tends to zero.

Against a metaphysical understanding of rejection Rubín, Mariela; Roffé, Ariel Jonathan In this article, we defend that incorporating a rejection operator into a paraconsistent language involves fully specifying its inferential characteristics within the logic. To do this, we examine a recent proposal by Berto (2014) for a paraconsistent rejection, which - according to him - avoids paradox, even when introduced into a language that contains self-reference and a transparent truth predicate. We will show that this proposal is inadequate because it is too incomplete. We argue that the reason it avoids trouble is that the inferential characteristics of the new operator are left (mostly) unspecified, exporting the task of specifying them to metaphysicians. Additionally, we show that when completing this proposal with some plausible rules for the rejection operator, paradoxes do arise. Finally, we draw some more general implications from the study of this example.

Modelo digital del terreno mediante relevamientos con GNSS; Digital terrain model through GNSS measurings Neuman, Karina; Zapperi, Paula Andrea; Aldalur, Nélida Beatri; Campo, Alicia Maria; Bongiovanni, Ariel; Pischel, Diana La información topográfica de alta precisión es primordial en diferentes estudios delmedioambiente. Es por ello que el objetivo del trabajo fue generar una grilla de basepara la elaboración de un MDT (Modelo Digital del Terreno) para la ciudad de BahíaBlanca a partir de puntos obtenidos con métodos directos. De esta manera, se planteó elrelevamiento planialtimétrico de las vías de circulación mediante técnicas de mediciónpor satélites. La altura de cada punto relevado fue llevada a altura ortométrica utilizandoel modelo geoidal GEOIDEAr. Para la validación del modelo se emplearon 44 puntosde control, de distinto origen y calidad. Se utilizaron puntos de la red de nivelación deprecisión y de alta precisión del IGN, puntos de la Dirección de Geodesia de laprovincia de Buenos Aires y puntos propios. En promedio, las diferencias entre elmodelo generado y los puntos de control de las distintas fuentes no superan los 35 cm.El mismo mejoró la confianza en el valor altimétrico comparando con modelospreexistentes, principalmente en la zona céntrica.; High-precision topographic information is essential in many environmental studies. This is why the objective of the work was to generate a base grid for the elaboration of a DTM (Digital Terrain Model) for Bahía Blanca city from points obtained by direct methods. In this way, the plane altimetric survey of the roadways was proposed through satellite measurement techniques. The height of each measured point was taken to orthometric height using the GEOIDEAr geoid model. For the validation of the model, 44 control points of different origin and quality were used. Points of leveling precision network and high-precision of the IGN were used, points of the Dirección de Geodesia and own points. On average, the differences between the generated model and the control points of the different sources do not exceed 35 cm. This model improved confidence in the altimetric value compared to pre-existing models, mainly in the centric zone.

Clinical characteristics and comorbidities of elderly asthmatics who attend allergy clinics Yáñez, Anahí; Soria, Marcela; de Barayazarra, Norma Susana; Recuero, Nancy; Rovira, Francisco; Jares, Edgardo; Stok, Ana María; Nemirovsky, Sergio Ivan; Bueno, Carlos Alberto Background: To date, few studies have focused on the clinical and allergic characteristics of asthma in the elderly, defined as asthma in people aged 60 or over. Thus, we propose to identify and study the clinical and allergic characteristics and comorbidities of patients with asthma among the elderly.Methods: A retrospective, observational, descriptive study was developed in five clinics and hospitals in Argentina. Allergy Physicians analyzed their patients? medical records in 2014 and included those adults over the age of 60, who had been diagnosed with asthma according to the GINA guidelines. Clinical and allergic characteristics were analyzed.Results: A total of 152 patients diagnosed with asthma, of whom 73% were women and 11% ex-smokers, were included in this study, with a mean age of 66 years. Only 10.5% of the participants had onset asthma past the age of 60. Regarding asthma severity, 74.3% were diagnosed with moderate persistent asthma, and 7.2% with severe persistent asthma. Eighty-four percent of the patients were treated with an inhaled corticosteroid (ICS) along with a long-acting β 2-adrenergic agent (LABA). More than half of the patients had two or more comorbidities simultaneously. Allergic comorbidities were the most frequent comorbidities, followed by arterial hypertension. Among allergic comorbidities, most patients presented allergies at the nasal level. There were no significant differences between the subpopulations of patients with late-onset asthma (LOA) and asthma with onset before the age of 60, i.e. early onset asthma (EOA) in most of their clinical characteristics. However, it was observed that EOA accounted for a higher percentage of patients with nasal allergies as compared to LOA (71% vs 46%, p < 0.05).It is worth mentioning that almost half of the patients with LOA had allergies at the nasal level.Conclusion: These results may provide a better understanding of the clinical characteristics of asthma in the elderly in Argentina, thus, enabling the development of future therapeutic strategies and a better quality of life for our elderly asthma patients.

Anticuerpos anti-B13 en infectados crónicos por Trypanosoma cruzi y su asociación con la cardiopatía chagásica Olivera, Lorena Veronica; Bizai, María Laura; Arias, Evelyn; Suasnábar, Santiago Martín; Marcipar, Iván Sergio; Fabbro, Diana Lucrecia La proteína B13 inmunodominante de Trypanosoma cruzi, presenta una secuencia homóloga (AAAGDK) a la cadena pesada de miosina cardíaca humana (AAALDK) asociada a mimetismo molecular, posible mecanismo patogénico en la enfermedad de Chagas. El objetivo de este trabajo fue analizar, en adultos infectados crónicos con Trypanosoma cruzi, la asociación entre los niveles de anticuerpos anti-B13 y desarrollo de cardiopatía chagásica.Se realizó un estudio transversal en 89 pacientes con infección crónica por Trypanosoma cruzi distribuidos en: 34 infectados sin patología demostrable (grupo A); 42 infectados con cardiopatía chagásica crónica de diferente severidad (grupo B) y; 13 infectados con miocardiopatía chagásica y factores de riesgo cardiovasculares asociados (grupo C). Como grupo control se estudiaron 46 personas no infectadas con Trypanosoma cruzi: 16 con cardiopatía (grupo D) y 30 sanas (grupo E). Además en 13 pacientes del grupo B, edad promedio de 43,3±13,2 años, se realizó un estudio de cohorte retrospectivo con seguimiento de 12,6±6,5 años, a fin de correlacionar el nivel de respuesta anti-B13 y la progresión de la cardiopatía. Estos pacientes no presentaron cambios en los niveles de anticuerpos anti-B13 a través del tiempo, independientemente de la evolución clínica.No se observaron diferencias significativas entre los grupos A, B y C tanto en la presencia de anticuerpos anti-B13 (A=91,1%, B=80,8% y C=84,6%), como en el nivel de respuesta de los mismos. Sin embargo, en los pacientes del grupo B con alto compromiso cardíaco los niveles de anticuerpos anti-B13 fueron más elevados.Los pacientes del grupo control con cardiopatía, 50% fueron positivos para anticuerpos anti-B13 aunque con muy escasa reactividad, mientras las personas sanas no presentaron respuesta a esta proteína.Si bien no se encontró asociación entre el nivel de anticuerpos anti-B13 y cardiopatía chagásica, se observaron valores más altos en los infectados con compromiso cardíaco severo, sin variación en el tiempo.Estos resultados sugieren que los anticuerpos anti-B13 podrían ser utilizados como marcadores de progresión clínica en lo pacientes con cardiopatía chagásica crónica.

Evidence for the associated production of the Higgs boson and a top quark pair with the ATLAS detector Aaboud, M.; Aad, G.; Abbott, B.; Abdinov, O.; Abeloos, B.; Alconada Verzini, María Josefina; Alonso, Francisco; Arduh, Francisco Anuar; Dova, Maria Teresa; Hoya, Joaquín; Monticelli, Fernando Gabriel; Wahlberg, Hernan Pablo; Bossio Sola, Jonathan David; Daneri, María Florencia; Devesa, Maria Roberta; Marceca, Gino; Otero y Garzon, Gustavo Javier; Piegaia, Ricardo Nestor; Sacerdoti, Sabrina; Zinonos, Z.; Zinser, M.; Ziolkowski, M.; Živković, L.; Zobernig, G.; Zoccoli, A.; Zoch, K.; Nedden, M. zur; Zorbas, T. G.; Zou, R.; Zwalinski, L.; The ATLAS Collaboration A search for the associated production of the Higgs boson with a top quark pair (ttH¯ ) is reported. The search is performed in multilepton final states using a dataset corresponding to an integrated luminosity of 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at a center-of-mass energy √ s = 13 TeV at the Large Hadron Collider. Higgs boson decays to WW∗ , ττ, and Z Z∗ are targeted. Seven final states, categorized by the number and flavor of charged-lepton candidates, are examined for the presence of the Standard Model Higgs boson with a mass of 125 GeV and a pair of top quarks. An excess of events over the expected background from Standard Model processes is found with an observed significance of 4.1 standard deviations, compared to an expectation of 2.8 standard deviations. The best fit for the ttH¯ production cross section is σ(ttH¯ ) = 790+230 −210 fb, in agreement with the Standard Model prediction of 507+35 −50 fb. The combination of this result with other ttH¯ searches from the ATLAS experiment using the Higgs boson decay modes to bb¯, γγ and Z Z∗ → 4`, has an observed significance of 4.2 standard deviations, compared to an expectation of 3.8 standard deviations. This provides evidence for the ttH¯ production mode.

En busca del calor perdido: Efecto Seebeck y materiales termoeléctricos Cornaglia de la Cruz, Pablo Sebastian La generación y el uso racional de la energía constituyen una problemática de importancia central en Argentina y en el mundo. Los desafíos consisten en administrar las fuentes no renovables de energía, disminuir los costos y mejorar la eficiencia en el uso de un recurso esencial para la actividad industrial y la calidad de vida. Un aspecto muy importante para mejorar la eficiencia en el uso de la energía es reducir las altas pérdidas en forma de calor residual que se producen al utilizar combustibles fósiles. En el caso de los automóviles, sus motores aprovechan menos de un tercio de la energía disponible en la nafta. Los dos tercios restantes se pierden en forma de calor en los gases del escape y en el sistema de refrigeración del motor. En la Argentina dos tercios de la energía eléctrica se genera a partir de la combustión de gas natural y las centrales térmicas más modernas sólo logran aprovechar poco más de la mitad de la energía disponible del gas. Aprovechar el calor residual es un desafío para científicos y tecnólogos con motivaciones tanto económicas como ambientales.En ese sentido ha resurgido el interés en los materiales llamados termoeléctricos que pueden ser utilizados para generar electricidad a partir de una fuente de calor (como el caño de escape de un auto que emite gases a alta temperatura). Los dispositivos construidos en base a estos materiales no tienen partes móviles, como las que hay en el alternador de un auto, y por lo tanto son silenciosos y no necesitan de mantenimiento ya que en ellos no se produce desgaste mecánico. Además, al tener un peso y tamaño reducidos, es posible utilizarlos en autos o aviones. En los últimos años ha resurgido la búsqueda de nuevos materiales termoeléctricos con el fin de disminuir su costo y mejorar su eficiencia para lograr una utilización masiva de los mismos.

Mutations involving the SRY-related gene SOX8 are associated with a spectrum of human reproductive anomalies Portnoi, Marie-France; Dumargne, Marie Charlotte; Rojo, Sandra; Witchel, Selma F; Duncan, Andrew J; Eozenou, Caroline; Bignon Topalovic, Joelle; Yatsenko, Svetlana A; Rajkovic, Aleksandar; Reyes Mugica, Miguel; Almstrup, Kristian; Fusee, Leila; Srivastava, Yogesh; Chantot Bastaraud, Sandra; Hyon, Capucine; Louis Sylvestre, Christine; Validire, Pierre; de Malleray Pichard, Caroline; Ravel, Celia; Christin Maitre, Sophie; Brauner, Raja; Rossetti, Raffaella; Persani, Luca; Charreau, Eduardo Hernan; Dain, Liliana Beatriz; Chiauzzi, Violeta Alicia; Mazen, Inas; Rouba, Hassan; Schluth Bolard, Caroline; Mac Gowan, Stuart; Mc Lean, W. H. Irwin; Patin, Etienne; Rajpert De Meyts, Ewa; Jauch, Ralf; Achermann, John C.; Siffroi, Jean Pierre; Mc Elreavey, Ken; Bashamboo, Anu SOX8 is an HMG-box transcription factor closely related to SRY and SOX9. Deletion of the gene encoding Sox8 in mice causes reproductive dysfunction but the role of SOX8 in humans is unknown. Here, we show that SOX8 is expressed in the somatic cells of the early developing gonad in the human and influences human sex-determination. We identified two individuals with 46,XY disorders/differences in sex development (DSD) and chromosomal rearrangements encompassing the SOX8 locus and a third individual with 46,XY DSD and a missense mutation in the HMG-box of SOX8. In-vitro functional assays indicate that this mutation alters the biological activity of the protein. As an emerging body of evidence suggests that DSDs and infertility can have common etiologies, we also analyzed SOX8 in a cohort of infertile men (n = 274) and two independent cohorts of women with primary ovarian insufficiency (POI; n = 153 and n = 104). SOX8 mutations were found at increased frequency in oligozoospermic men (3.5%; p<0.05) and POI (5.06%; p=4.5x10-5) as compared to fertile/normospermic control populations (0.74%). The mutant proteins identified altered SOX8 biological activity as compared to the wild-type protein. These data demonstrate that SOX8 plays an important role in human reproduction and SOX8 mutations contribute to a spectrum of phenotypes including 46,XY DSD, male infertility and 46,XX POI.

Estimación del consumo en rumiantes en pastoreo utilizando redes neuronales artificiales Uhrig, Mariela Noelia; Galli, Julio Ricardo; Rufiner, Hugo Leonardo; Milone, Diego Humberto Accurate and rapid measurement of forage intake in ruminants is important for efficient management livestock and forage resources, as well as for animal health and welfare in production systems. The use of intelligent signal processing algorithms to extract relevant information from the sound emitted by ruminants is a promising method to predict the intake of ruminants in grazing conditions. In this work, multilayer perceptrons and extreme learning machines, are used as non-linear multivariate regression models to predict intake. The results show that these non-linear regression techniques can significantly reduce the error in the estimation of forage intake in ruminants.

Toxoplasmosis congénita: Diagnóstico serológico, RPC, aislamiento y caracterización molecular de Toxoplasma gondii. Carral, Liliana; Kaufer, Federico; Pardini, Lais Luján; Durlach, Ricardo; Moré, Gastón Andrés; Venturini, María C.; Freuler, Cristina Congenital toxoplasmosis diagnosis in the newborn is a very important issue due to the need for early treatment to prevent future sequels. Aim: To compare available methods at the institution for the diagnosis of congenital toxoplasmosis. Material and Methods: In this study we have evaluated the different diagnostic tests used in 67 congenital exposed newborns, including serological tests, PCR, parasite isolation and molecular characterization. Results: The ISAGA IgM and IgA tests showed sensitivity (Se) of 87 and 91%, respectively, and specificity (Sp) of 100%. When ISAGA IgM and IgA were performed simultaneously, the Se increased to 98% and the Sp was 100%. The presence of IgE contributed to the diagnosis when it was detected in the child?s serum but not in maternal blood. In four congenital infected children the parasite was isolated and genotyped: one was genotype II and the other three were ?atypical? genotypes. No parasite was isolated in children without congenital toxoplasmosis. Discussion: Overall, serological tests showed a good diagnostic performance although in one case they were all negative and isolation was the only tool to identify the infection. We conclude that it is essential to use all diagnostic tests in every single exposed child, including if possible, molecular characterization due to its epidemiological implication.

Saberes botánicos en el talar: utilización de plantas silvestres con fines medicinales y alimenticios en el Parque Costero del Sur (partidos de Magdalena y Punta Indio, Buenos Aires, República Argentina); Conhecimento botânico no talar: uso de plantas silvestres com fins medicinais e alimentícios no Parque Costero del Sur (Região de Magdalena e Punta Indio, Buenos Aires, República Argentina); Botanical knowledge of talar: use of wild plants for medicinal and food purposes in Parque Costero del Sur (Regions of Magdalena and Punta Indio, Buenos Aires, Argentina) Ghiani Echenique, Naiquen Martina; Doumecq, María Belén; Pochettino, María Lelia La Reserva de Biosfera "Parque Costero del Sur" (PCS) se encuentra ubicada en los partidos de Magdalena y Punta Indio, en el noreste de la Provincia de Buenos Aires. Esta figura de protección se fundamenta en su riqueza en biodiversidad, donde la presencia del bosque costero, constituido por talares, se conjuga con ambientes de bañados y playa. Resulta de interés indagar la diversidad vegetal del PCS y su aprovechamiento por parte de los habitantes locales con miras a su constitución como patrimonio intangible.

This protected unit is based on its richness in biodiversity, where the coastal forest, constituted by the talar, combines with wetland environments and beach. It is of interest to research the plant diversity of the PCS and its utilization by local people with regards to become an intangible heritage. Therefore, from ethnobotanical point of view, the use of wild plant resources for food and medicinal purposes in PCS was characterized. By interviewing local residents, 54 used plant species have been recorded, as well as the related knowledge and practices together with the modes of use and the conditions under which harvest and consumption take place. The analysis of local botanical knowledge allowed us to reflect the assessment of these species as food or medicine and its importance to the present population, as well as to inquire about the possibility of a different evaluation of medicinal and food plants harvest. The obtained results propose to promote the participation of residents in training activities on local plant resources. In this respect, a booklet will be produced and distributed to the residents and visitors of the PCS as well

History of German Philology in Argentina (Chapter 2); Geschichte der argentinischen germanistik. Bujaldon, Lila Estela Diese Studie zur Geschichte der Germanistik in Argentinien befasst sich mit der Zeitspanne zwischen der Mai-Revolution 1810 -d.h. der Zeit nach der Unabhängigkeit von Spanienund den 50er Jahren. Die Studie setzt das Augenmerk auf die Geschichte des Studiengangs an der Universität Buenos Aires. Als erstes wird die Wissenschaftsgeschichte der Germanistik dargestellt. Daran anschließend wird die Entwicklung der Fremdsprachenlehre –u.a. der deutschen Sprache– von der Kolonialzeit bis zu den ersten Jahren des 20. Jahrhunderts untersucht. Ein Kapitel ist der lokalen Bezeichnung der Germanistik gewidmet: „Literatur des nördlichen Europa“. Auch die Biographien der ersten Professoren Deutscher Literatur an der Universität Buenos Aires –Mauricio Nirenstein, Albert Haas und Juan Carlos Probst– werden in weiteren Kapiteln eingehend untersucht. Das Schlusskapitel stellt darüber hinaus die Arbeit von Werner Bock, Ilse M. de Brugger und Gúnter Ballin vor. Alle haben während des Deutschen Exils 1933 in Argentinien Zuflucht gefunden und gaben die Deutsche Literatur in der akademischen und intellektuellen Szene bekannt.; This study of the history of German philology in Argentina describes and analyses the period of time between the Revolution of May 1810, which means after the independence of Argentina from Spain, and the 1950s. The study has its focus on the history of the degree program of the University of Buenos Aires. In the first chapter, the history of the science of German language and literature studies and the development of foreign language studies are addressed (among other things, German language), covering the period from the colonial era until the first years oft he 20th century.

Cinodontes triásicos y mamíferos del tiempo de los dinosaurios Martinelli, Agustín Guillermo; Soares, Marina; Forasiepi, Analia Marta Cómo eran los mamíferos que coexistieron con los dinosaurios y sobrevivieron a la extinción de estos, y cómo eran sus ancestros inmediatos, los cinodontes, de los que se diferenciaron hace unos 210Ma.

Validation of the subtle and blatant prejudice scale towards indigenous people in Argentina Ungaretti, Joaquín; Etchezahar, Edgardo Daniel; Barreiro, Alicia Viviana The aim of this study was to analyze the psychometric properties of the subtle and blatant prejudice scale toward indigenous people inArgentina and its relationship with right wing authoritarianism, social dominance orientation, tolerance for disagreement, ideologicalpoliticalself-positioning, sex and age.Asample of 304 participants from Buenos Aireswas selected using a non-probabilistic incidentalmethod. Participants were aged from 18 to 41 years and they were asked to fill a self-report questionnaire including an Argentineanversion of the subtle and blatant prejudice toward indigenous people scale together with right wing authoritarianism scale, socialdominance orientation scale, tolerance for disagreement scale, ideological-political self-positioning scale.We found adequate psychometricsproperties for the subtle and blatant prejudice scale, as well as significant and positive correlations with right wing authoritarianism,tolerance for disagreement, social dominance orientation and political self-placement. These findings may indicate thatprejudice towards indigenous people in Argentina is a complex problem that cannot be explained only by considering intergrouprelations, because different socio-psychological variables are related with its consolidation and maintenance.

Archaeological science in southern South America: An introduction Morales, Marcelo Raul; Tessone, Augusto; Barberena, Ramiro The approach that can be succinctly described as ‘archaeological science’ has grown beyond any predictions made during the last four decades. Recently published data helps to illustrate the magnitude of this evolution. In 1982 the Journal of Archaeological Science published four issues with 28 articles that occupied 409 pages, while in 2014 it published 12 issues containing 480 articles spanning 5128 pages (Torrence et al., 2015, 1–2). This is the historical context of the discipline where the Journal of Archaeological Science: Reports emerged in 2015 as a sister publication aimed at disseminating the ever-growing “… results of the application of scientific methods to archaeological problems and debates, as well as providing a forum for reviews and discussion of issues in scientific archaeology and their impact in the wider subject” (Hunt and Howard, 2015, 1).

Characterization and cancer risk assessment of VOCs in home and school environments in gran La Plata, Argentina Colman Lerner, Jorge Esteban; Gutierrez, María de Los Angeles; Mellado, Daniela; Giuliani, Daniela Silvana; Massolo, Laura Andrea; Sánchez, Érica Yanina; Porta, Atilio Andrés Three areas are highlighted in Gran La Plata, Argentina: industrial, urban, and residential. In this work, the levels of volatile organic compounds (VOCs) in indoor air of homes and schools in those areas were analyzed, through the use of passive monitors. The study period is between 2007 and 2010. Higher levels of VOCs were found in homes and schools in the industrial zone, higher than the levels corresponding to urban and residential. Taking into account the relationship between indoor and outdoor levels of VOCs, they have ratios (I/O) between 1.5 and 10 are evidenced contributions of emission sources of VOCs both indoor and outdoor. Complementarily, we estimated the life time cancer risk (LCR) for benzene, styrene, trichloroethylene, and tetrachloroethylene in children who spend their time mostly in such indoor environments. The results show high LCR values for benzene, which exceed acceptable values for the US EPA.

Severe plastic deformation by equal channel angular pressing and rolling: The influence of the deformation path on strain distribution Kliauga, Andrea M.; Sordi, Vitor L.; de Vincentis, Natalia Soledad; Bolmaro, Raul Eduardo; Schell, Norbert; Brokmeier, Heinz-Günter The present work compares two deformation techniques, rolling and Equal Channel Angular pressing (ECAP), and the response offered by three different materials that differ in Stacking Fault Energy (SFE): AA1010 Al, commercially pure Cu, and an austenitic stainless steel. The objective of this investigation is to study the effect of each deformation mode on tensile behavior, deformation mechanism, texture, and microstructure and to establish the influence of the stacking fault energy on said effects. The results show that the different strain paths of ECAP and rolling do not affect the strength, but rolling leads to an accentuated texture and thus to elastic and plastic anisotropy. This finding has practical relevance for micro manufacturing techniques. Furthermore, it is observed that lower SFE results in smaller domain size and higher dislocation density, which are microstructural details related to strength and to the work hardening capacity. Finally, both techniques are able to produce a high amount of high angle grain boundaries, a feature that characterizes refined microstructures. These processes operate at different strain rates; thus, in low SFE materials, a more effective grain fragmentation by deformation-induced twins is observed after the ECAP process.

Effect of structure, morphology and chemical composition of Zn-Al, Mg/Zn-Al and Cu/Zn-Al hydrotalcites on their antifungal activity against A. niger Velázquez Herrera, Franchescoli Didier; Fetter, Geolar; Rosato, Vilma Gabriela; Pereyra, Andrea Marisa; Basaldella, Elena Isabel Zn-Al, MgZn-Al and CuZn-Al hydrotalcites were prepared by the co-precipitation method, using the conventional hydrothermal crystallization or ultrasonic irradiation methods The samples were characterized by XRD, FT-IR and SEM, which confirmed the formation of a layered double hydroxide phase. Afterwards, the effects of composition and texture of the synthesized samples on their biocidal behavior against A. niger were evaluated by using traditional cultivation techniques. Among the different samples examined, hydrotalcites containing Zn, Zn-Mg and Zn-Cu showed an inhibitory effect on A. niger growth. Samples synthesized by the conventional method showed a greater inhibitory capacity than those synthesized by ultrasonication, but their biocidal activity was mainly determined by the presence of biocidal cations. The biocidal characteristics of zinc and/or copper in conjunction with the alkalinity of these materials were favorable for preventing fungal spread. The ZnAl hydrotalcite, the more eco-friendly material of the analyzed series, showed a good biocide performance, while the best antifungal behavior was observed for copper-containing hydrotalcites.
