“User generated” content is a new popular type of content that shows potential in communicating information to younger age groups in new, creative ways. This study aimed to assess the impact of a “user generated” video in communicating about marine environmental threats, specifically to one hundred and fifty-one young adults enrolled in two different schools: a private higher education school, and a public university, both in the Lisbon metropolitan area (Portugal). The video’s impacts in the cognitive and emotional fields were assessed by comparing them to the impacts of an outreach text similar in content and duration of exposure. A pre-test/post-test methodology was used to evaluate short-term impacts, and a follow-up test was applied to gauge medium-term impacts. Additionally, short focus group sessions further explored topics such as media consumption preferences and trends. The results suggest that “user generated” video has a similar impact to an outreach text in the cognitive field, and a bigger impact in the emotional field when it comes to promoting positive emotions and feelings. Therefore, when used to its full potential, this type of media can be a suitable way to communicate about science and environmental topics, particularly marine environmental threats, and a valuable tool to raise public awareness.

The confrontation of situations of violence that are manifested in the educational community, is the way to recognize and consider the school, as the social institution responsible for promoting education and teaching that emphasizes the values of tolerance and peace. The objective of this article is to offer a professional development program for teachers to deal with situations of violence in the educational community. For the development of the research, a study was carried out based on the general method of materialist dialectics, using methods from the theoretical level (analysis and synthesis, induction and deduction, systematization and the system approach), from the empirical level (observation and interview), as well as statistical-mathematical (descriptive statistics), which made it possible to propose the improvement program as a response to the needs of teachers to face, from a bio-psycho-social approach, where methods and procedures for the prevention and correction-compensation of the consequences that originate in students, situations of violence in the educational community. It is considered that this result contributes to the fact that the educational communities have in their hands a tool that facilitates the fulfillment of the rights of schoolchildren to education, health and well-being and, in turn, to the fulfillment of the Development Goals. Sustainable established until 2030.

Abstract We report a molecular modeling paradigm to describe silica polymerization reactions in aqueous solutions at conditions that are representative of realistic experimental processes like biosilicification or porous silica synthesis – i.e. at close to ambient temperatures and over a wide range of pH. The key point is to describe the Si-O-Si chemical bond formation and breakage processes through a continuous potential with a balance between attractive and repulsive interactions between suitably placed virtual sites and sticky particles. The simplicity of the model, its applicability in standard parallelized molecular dynamics codes, and its compatibility with the widely used MARTINI coarse-grained force-field allows for the study of systems containing millions of atoms over microsecond time scales. The model is calibrated to match experimental results for the temporal evolution of silica polymerization in aqueous solution close to the isoelectric point, and can describe silica polymerization and self-assembly processes during encapsulation of a surfactant micelle.

En este trabajo, se parte de considerar la Educación para el Desarrollo Sostenible como una alternativa pedagógica viable y necesaria para contribuir al logro de los Objetivos de Desarrollo Sostenible definidos hasta el 2030.

El objetivo de la investigación fue evaluar el vigor en el cultivo de jamaica (Hibiscus sabdariffa L.) utilizando rizobacterias de Pseudomonas fluorences bajo condiciones de estrés ocasionado por sulfato de cobre (CuSO4), como una alternativa para la fitorremediación de suelos contaminados con aguas residuales. El experimento se realizó en las instalaciones del Colegio de Postgraduados, Campus Montecillo, México. Se utilizaron semillas de dos variedades de jamaica (var. Criolla y var. Araña) inoculadas con células de seis cepas bacterianas (M83, M67, M88, L168, M82_A y M82_C), las cuales fueron sembradas y cultivadas en un invernadero para determinar: longitud del tallo (LT), longitud de la raíz (LR), biomasa seca de la raíz (BSR), contenido de clorofila (CCL), número de hojas (NH), diámetro del tallo (DT) y volumen radical (VR). El diseño experimental implementado fue de bloques completamente al azar con un arreglo factorial (4 x 2 x 2 x 2). Las concentraciones de CuSO4 utilizadas en la siembra fueron 10-2 de concentración molar (M) para la var. Criolla y 10-6 M para la var. Araña. El tipo de suelo fue determinante porque causó diferencias significativas en la mayoría de las variables evaluadas, excepto en la LR, BSR y VR. La inoculación con cepas bacterianas causó inhibición en el crecimiento del DT en la var. Araña a los 80 días después de la siembra (dds). Las cepas que promovieron el crecimiento vegetal de las plantas de jamaica fueron la M83, M67 y M82 utilizadas en ambas variedades. Se concluye que las plantas de jamaica no presentaron efectos negativos debido a la condición de estrés causada por CuSO4. De manera general, la variedad que tuvo una mayor tolerancia al CuSO4 fue la var. Criolla, por lo cual, se puede considerar como una alternativa para la fitorremediación de suelos contaminados con aguas residuales.

Most of the farmers who grow cactus pear (Opuntia albicarpa) use manure as a fertilizer. This practice increases the problems of pests. The use of endomycorrhiza (Glomus intraradices) is almost unknown to farmers. Therefore, the objective of this research was to study the effect of the application with organic matter (OM) and inoculation with endomycorrhiza in cactus pear. The study was conducted under greenhouse conditions at the Montecillo Campus of the Postgraduate College, Mexico. Two types of soil from San Luis Potosí, Mexico were used, one of reddish coloration (xerosol) and another gray (lithosol). The results show that there were significant differences (p ≤ 0.05) in all the variables by the inoculation with endomycorrhiza, and in the majority of those by the application of OM. Both the mycorrhiza and the application of OM, as vermicompost, promoted a greater growth of the stem and the root. The types of soils used did not affect the growth of the plants. The mycorrhiza can be useful to improve mineral nutrition, and thus increase yields in the cactus pear plantations. In addition, these fungi can increase yields, and help reduce production costs. The application of 50 t ha-1 of vermicompost is a better alternative to add nutrients and OM to this crop.

El objetivo de este trabajo fue estudiar la relación entre la concentración de mucina salival y la enfermedad periodontal. La muestra se dividió en tres grupos de 20 individuos cada uno: Grupo 1 sin enfermedad periodontal; Grupo 2 con gingivitis; y Grupo 3 con periodontitis. En todas las muestras salivales se confirmó la presencia de mucina, el Grupo 1 presentó un valor promedio de 1,27 mg/ml. En el Grupo 2 se registró un promedio de 1,93 mg/ml. En el Grupo 3 se observó un promedio de 3,01 mg/ml. El Análisis de la Variancia y posterior prueba de F (F = 25,01, p < 0,0001) confirman diferencias significativas en los contenidos de mucina entre grupos. El aumento de la concentración de mucina salival en pacientes periodontales podría representar un marcador químico de utilidad como coadyuvante en el diagnóstico clínico de esta enfermedad.

The article is part of the research project "Integrative conception of the promotion of health and natural sciences in the initial and permanent teacher training", from the University of Pinar del Río "Hermanos Saíz Montes de Oca". It is an experimental research, in its pre-experimental variant and aimed to develop a pedagogical strategy that contributes to the comprehensive education of sexuality with a pedagogical professional approach, in the students of pedagogical careers. The methodological base was assumed as the dialectical-materialist method, which supported the use of methods of the theoretical level, used in the determination of the theoretical referents of the research and empirical level methods were used, which allowed to verify the current state of integral education of sexuality, in the students of the sample. The designed strategy is based on a system of principles, in which the principle of double intentionality of the integral education of sexuality in the training of teaching staff is emphasized. Its implementation in practice allowed the appropriation of content related to sexuality as a personality dimension, placing the student at the center of the process, such as being sexed, both individually and professionally, with the mission of contributing to education of the sexuality of others, a task that is part of his role as a teacher, which proved the validity of the proposal.

Background: Knowledge is increasing about TSC-Associated Neuropsychiatric Disorders (TAND), but little is known about the potentially confounding effects of intellectual ability (IA) on the rates of TAND across age, sex, and genotype. We evaluated TAND in (a) children vs. adults, (b) males vs. females, and (c) TSC1 vs. TSC2 mutations, after stratification for levels of IA, in a large, international cohort.Methods: Individuals of any age with a documented visit for TSC in the 12 months prior to enrolment were included. Frequency and percentages of baseline TAND manifestations were presented by categories of IA (no intellectual disability [ID, intelligence quotient (IQ)>70]; mild ID [IQ 50–70]; moderate-to-profound ID [IQ

El texto examina la transformación territorial de dos ejidos (Nexquipayac y Atenco) que conforman al municipio de Atenco desde la perspectiva de género. Los datos fueron obtenidos entre octubre de 2014 y junio de 2016, mediante análisis documental, observación participante, entrevistas, talleres y cuestionarios. Describe la vocación lacustre y agropecuaria de ambos ejidos, para documentar la transformación del territorio a raíz de nuevos usos ocupacionales del suelo, alteraciones del ecosistema, conflictos en torno a la tenencia de la tierra y, más recientemente, a causa de la aprobación del dominio pleno y la venta de tierras para el nuevo Aeropuerto Internacional de la Ciudad de México, anunciado por Enrique Peña Nieto en septiembre de 2014. Concluye que hay una pérdida de recursos naturales y que las mujeres perciben de manera negativa las transformaciones del territorio, lo que ha dado lugar a un proceso de desterritorialización.

La periurbanización se ha considerado como motor del cambio de uso del suelo y de la pérdida de ecosistemas y de biodiversidad. A partir de esta premisa, la investigación plantea el seguimiento, desde una doble perspectiva, histórica y predictiva, de los cambios en la superficie de los humedales y en la deforestación progresiva entorno a Villahermosa, la urbe más importante de la cuenca del río Grijalva, en el Estado de Tabasco (México). Se han utilizado diferentes métodos: el análisis bibliográfico para el periodo desde la fundación de la ciudad hasta el último tercio del siglo XX, la verificación de fotografías aéreas entre 1984 y 2008 y la modelización de escenarios futuros, entre 2020 y 2040. Desde el periodo colonial hasta mediados del siglo veinte, las inundaciones y la insalubridad dificultaron el crecimiento de la ciudad pese a la transformación de la red hídrica superficial en la cuenca, iniciada mediante la construcción de diques en el siglo XVII. Posteriormente, las elevadas tasas de pérdida de humedales y deforestación (-0.50 y -4.63 %) se incrementaron por la urbanización y el impacto de los programas de producción agropecuaria y petrolización. En los últimos 40 años, el desarrollo periurbano ocasionó la pérdida de 4.008 ha de vegetación arbórea y 289 ha de humedales, con una tendencia a desaparecer 1.449 y 356 ha adicionales respectivamente en el futuro 2040. Estos resultados resaltan la necesidad de rediseñar un programa metropolitano, transdisciplinario y sustentable que respete y actualice las reservas territoriales para regular la periurbanización.

Todo estudio que concierna a la pasión del odio (pasión que como tal es ubicable ya en la problemática del espejo) deberá tener en cuenta que la audibilidad e inaudibilidad, la aceptación y el rechazo de la invocación originaria, se dan en un tiempo que no es mítico ni histórico dentro del cual lo inexistente es llamado a advenir en relación con una voz encarnada. Freud descubrió que el odio precede al amor que viene a recubrirlo y, por lo tanto, el odio es primero pero no primario. El sujeto se constituye en una relación con el Otro que es de “exclusión interna”, en un rechazo primordial que es también aceptación. Ese momento lógico, de coalescencia y soldadura, de corte y anudamiento, propicia ese montaje escénico en que el hombre odia al otro que hay en él, el más cercano y el más extraño.

Background and Objectives: Prostaglandin E2 (PGE2) is present in gingival crevicular fluid the (GCF) and is evidenced in periodontal disease (PD). However, there are no enough reports to correlate the PGE2 concentrations in GCF in periodontal health and disease with clinical and radiographic indicators, age and gender. Hence, the present study is aimed to estimate the levels of PGE2 in GCF of subjects without periodontal disease (SEP) and periodontal disease (CEP). Materials and Methods: 99 subjects were selected, 33 without PD (G1) and 66 with PD, 33 with gingivitis (G2) and 33 with periodontitis (G3), which were submitted to a clinical and radiographic diagnosis, registering samples FGC, being stored, centrifuged and refrigerated for preservation. Subsequently the concentration of crevicular PGE2 was measured by using the enzyme linked immunosorbent assay (ELISA), determining the concentration of each subject. Results: PGE2 was detected in all the samples. The G1 presented a concentration of 28.82 ± 2.88 pg / mL, G2 44.91 ± 4.37 pg / mL and G3 148.67 ± 74.74 pg / mL (p

O presente artigo tendo por base o universo teatral na sua dimensão cénica e na perspetiva literária, explora uma pedagogia renovada no ensino da Filosofia ao nível do ensino secundário. Pretende-se neste trabalho destacar as bases de uma investigação que será levada a cabo no Balleteatro - Escola Profissional, durante dois anos com alunos do ensino secundário, no sentido de testar novas metodologias de ensino da Filosofia através do teatro. Pretendemos, assim, valorizar a relação intima que o teatro sempre manteve com a Filosofia e nessa abordagem fundamentar a necessidade de uma educação filosófica que efetivamente se sirva de um conjunto de métodos e exercícios que suportam a exigência da atividade racional a que a Filosofia obriga e o deleite sensorial que o teatro proporciona, estabelecendo, desta forma uma maior aproximação entre a disciplina de Filosofia e a formação da sensibilidade ética e estética dos alunos.

En el desarrollo de la enfermedad periodontal (EP) intervienen enzimas derivadas tanto del huésped como de los microorganismos presentes en la placa dental.

La fosfatasa alcalina, la β-glucuronidasa, la catepsina B, las MMP-8 y MMP-9, la elastasa y las Dipeptidil peptidasas II y IV, son útiles en el monitoreo y la planificación del tratamiento. La catepsina B, la MMP-8, la elastasa, las dipeptidil peptidasas II y IV, son utilizadas para diferenciar la gingivitis y la periodontitis. Las exotoxinas bacterianas del Aggregatibacter actinomycetemcomitans, indican la severidad de la enfermedad periodontal agresiva y ayudan al pronóstico del caso.

RESUMEN Se proyectó un escenario de uso del suelo en la cuenca del río Metztitlán al 2025 utilizando cadenas de Markov-autómatas celulares. Se utilizó un mapa generado para 2007 con imágenes Landsat 5 y Landsat 7 e imágenes SPOT 5 y 6 para 2013. La agricultura de temporal, la agricultura de riego y el bosque experimentarán un decremento en superficie. Los usos de suelo urbano, matorral, y matorral erosionado muestran un incremento en superficie. Las probabilidades de permanencia muestran que el uso urbano no representa una amenaza para el bosque con 1,7 %. Se registró una tasa positiva de deforestación para la superficie leñosa (1,42 %). Se recomienda que en futuras modelaciones se consideren variables de tipo socioeconómico y biofísico que puedan explicar con mayor detalle los procesos que limitan o favorecen el cambio de uso de suelo. Palabras clave: autómatas celulares, cadenas de Markov, cambio de uso del suelo, Landsat, SPOT.

Ternary blends of poly(lactic acid) (PLA), poly(3-hydroxybutyrate) (PHB) and poly(ε-caprolactone) (PCL) with a constant weight percentage of 60%, 10% and 30% respectively were compatibilized with soybean oil derivatives epoxidized soybean oil (ESO), maleinized soybean oil (MSO) and acrylated epoxidized soybean oil (AESO). The potential compatibilization effects of the soybean oil-derivatives was characterized in terms of mechanical, thermal and thermomechanical properties. The effects on morphology were studied by field emission scanning electron microscopy (FESEM). All three soybean oil-based compatibilizers led to a noticeable increase in toughness with a remarkable improvement in elongation at break. On the other hand, both the tensile modulus and strength decreased, but in a lower extent to a typical plasticization effect. Although phase separation occurred, all three soybean oil derivatives led somewhat to compatibilization through reaction between terminal hydroxyl groups in all three biopolyesters (PLA, PHB and PCL) and the readily reactive groups in the soybean oil derivatives, that is, epoxy, maleic anhydride and acrylic/epoxy functionalities. In particular, the addition of 5 parts per hundred parts of the blend (phr) of ESO gave the maximum elongation at break while the same amount of MSO and AESO gave the maximum toughness, measured through Charpy’s impact tests. In general, the herein-developed materials widen the potential of ternary PLA formulations by a cost effective blending method with PHB and PCL and compatibilization with vegetable oil-based additives.

The microbiological monitoring of the water used for hemodialysis is extremely important, especially because of the debilitated immune system of patients suffering from chronic renal insufficiency. To investigate the occurrence and species diversity of bacteria in waters, water samples were collected monthly from a hemodialysis center in upstate São Paulo and tap water samples at the terminal sites of the distribution system was sampled repeatedly (22 times) at each of five points in the distribution system; a further 36 samples were taken from cannulae in 19 hemodialysis machines that were ready for the next patient, four samples from the reuse system and 13 from the water storage system. To identify bacteria, samples were filtered through 0.22 µm-pore membranes; for mycobacteria, 0.45 µm pores were used. Conventional microbiological and molecular methods were used in the analysis. Bacteria were isolated from the distribution system (128 isolates), kidney machine water (43) and reuse system (3). Among these isolates, 32 were Gram-positive rods, 120 Gram-negative rods, 20 Gram-positive cocci and 11 mycobacteria. We propose the continual monitoring of the water supplies in hemodialysis centers and the adoption of effective prophylactic measures that minimize the exposure of these immunodeficient patients to contaminated sources of water.O monitoramento microbiológico da água utilizada no procedimento de hemodiálise é de extrema importância, principalmente devido à imunodebilidade dos pacientes com insuficiência renal crônica. Nosso objetivo foi verificar qualitativa e quantitativamente a presença de bactérias na água de um centro de hemodiálise do interior do Estado de São Paulo. Foram realizadas 22 coletas de cada um dos cinco pontos do sistema de distribuição; 36 amostras de 19 máquinas de hemodiálise, prontas para utilização; quatro amostras do sistema de reuso e 13 amostras do sistema de armazenamento de água, empregando-se a técnica da membrana filtrante com poros de 0,22 µm para bactérias e de 0,45 µm para micobactérias. A identificação foi realizada através de métodos microbiológicos convencionais e de biologia molecular. Isolados bacterianos foram obtidos de sistema de distribuição (128), águas das máquinas (43) e sistema de reuso (3). Entre os isolados 32 foram de bacilos Gram-positivos, 120 bacilos Gram-negativos, 20 Cocos Gram-positivos e 11 micobactérias. Neste estudo, sugerimos que suprimentos de água para o Centro de Hemodiálise devam ser monitorados, adotando-se medidas profiláticas eficazes que minimizem a exposição destes pacientes imunodeficientes a fontes aquáticas ambientais contaminadas.

A despeito da relativa freqüência de infecções fúngicas oportunísticas em pacientes sob hemodiálise, os reservatórios ambientais destes permanecem desconhecidos, embora alguns estudos recentes tenham correlacionado o suprimento de água como fonte desses microrganismos. O objetivo deste trabalho foi monitorar a qualidade micológica do sistema hídrico de uma Unidade de Hemodiálise, do interior do Estado de São Paulo, Brasil, no período entre abril e julho de 2006. Foram coletadas amostras (15), de 1000mL em 7 pontos de distribuição de água empregando-se técnica da membrana filtrante (0,45µm). Foram isolados 116 fungos filamentosos, dos quais 47 (40,5%) Trichoderma sp, 29 (25%) Cladosporium sp, 16 (13,8%) Aspergillus sp e 11 (9,5%) Fusarium sp. Mediante os resultados, sugerimos que suprimentos de água para Unidades de Hemodiálise devam ser monitorados também quanto ao aspecto micológico, adotando-se medidas profiláticas eficazes que minimizem a exposição destes pacientes imunodeficientes a fontes aquáticas ambientais contaminadas.Despite the relative frequency of opportunistic fungal infections among hemodialysis patients, the reservoirs for these microorganisms in the environment remain unknown, although some recent studies have made correlations with the water supply as their source. The objective of the present study was to monitor the mycological quality of the water system of a hemodialysis unit in the interior of the State of São Paulo, Brazil, over the period from April to July 2006. Fifteen samples of 1000 ml were collected from seven water distribution points using the membrane filtration technique (0.45 µm). A total of 116 filamentous fungus specimens were isolated, including 47 Trichoderma sp (40.5%), 29 Cladosporium sp (25%), 16 Aspergillus sp (13.8%) and 11 Fusarium sp (9.5%). The results suggest that the water supply for hemodialysis units should also be monitored for mycological contamination, and that effective prophylactic measures should be adopted for minimizing the exposure of these immunodeficient patients to contaminated water sources in the environment.

Se realizó un análisis temporal (2007-2013) de la dinámica de cambio de la cobertura vegetal y del uso de suelo en la cuenca río Metztitlán, Hidalgo, México con el objetivo de actualizar su estatus. Se utilizó un mapa generado para 2007 con imágenes Landsat 5 y Landsat 7 e imágenes SPOT 5 y 6 para 2013. Los resultados muestran que las áreas destinadas a la agricultura de riego y temporal disminuyeron en 34,8 y 25,6 %, respectivamente. El análisis de cambios indica que el uso urbano y los cuerpos de agua aumentaron 305,3 y 82,4 %, respectivamente. Se recomienda transitar del uso de imágenes de mediana resolución espacial (Landsat), al uso de imágenes de alta resolución (SPOT) si la intención es evaluar con detalle los cambios que acontecen en la región. Palabras clave: cambio de uso del suelo, cobertura de suelo, cuenca Metztitlán, Landsat, SPOT.

El tema de Cambio Climático (CC) es aún debatible, pero la evaluación de vulnerabilidad a eventos extremos es indispensable para un uso estratégico de los recursos públicos. Ejemplo reciente son los impactos de los ciclones “Ingrid” y “Manuel” que se hubieran aminorado si años atrás se hubiera evaluado la vulnerabilidad de la zona y distribuido recursos en concordancia. Este trabajo evaluó la vulnerabilidad a CC de una franja del centro del país hacia Golfo de México, alineada a la dirección que frecuentemente siguen los ciclones. Adaptado el modelo de Malone y Brenkert (2008), se emplearon como indicadores de vulnerabilidad variables socioeconómicas, biofísicas y climáticas. Los subcriterios más importante para vulnerabilidad al CC son el tamaño de la población, marginación, tecnología para la producción, degradación de los recursos naturales y capacidad económica. La evaluación de vulnerabilidad también se realizó dando peso diferenciado a las variables de acuerdo a la opinión de expertos, con resultados similares. La evaluación de la vulnerabilidad a CC mediante el modelo empleado es una herramienta de valiosa para detectar las áreas prioritarias para el uso de recursos y minimizar los impactos de eventos climáticos extremos.

Originally suggested by Rodriguez (2012), "trans generosity" aims to address the tensions and complexities of queer and trans pedagogies in educational settings. Using this concept, this study generates empirical insights on how queer and trans affirmative practices can disrupt heteronormativity, foster gender diversity and proactively emphasize the self-determination of trans students in schools and PE. Drawing on narrative ethnography, we relate the experiences of Lucas, a secondary trans student, during a period of four years, using the messy method of data collection. A dialogical narrative analysis helped to give sense to the "whats," the "hows," and the "effects" of Lucas's stories and storytelling within the narrative environment of the school. Legal and educational policy and academic frameworks provided Lucas and other actors with an adequate space for critical performances to foster the disruption of heteronormativity and broaden the circulation of (queer)gender narratives within the school. The dialogue, commitment, collaboration, and mutual trust between Lucas, his PE teacher and the school environment helped to make Lucas' trans affirmative stories tellable and coherent. This story of trans generosity may inspire other trans students, PE teachers, schools, or whoever wants to embrace queer and trans theories and pedagogies, to foster trans recognition and gender diversity education.

Nos últimos anos, os estudos de arte rupestre no Brasil têm tido um grande avanço quanto à construção de modelos interpretativos deste tipo de vestígio arqueológico ainda pouco conhecido e explorado. Apesar dos desafios em localizar, registrar e preservá-las ao longo do vasto território brasileiro, um número pequeno, mas devotado, de pesquisadores tem documentado e estudado minuciosamente milhares de pinturas e gravuras rupestres em várias regiões do país por meio de técnicas tradicionais. Apresentamos aqui um estudo de caso realizado no rio Madeira, no estado de Rondônia, no qual conjugamos a metodologia tradicional com novas tecnologias para o registro de gravuras rupestres, o laser scanning terrestre e a fotogrametria de luz estruturada. Essas novas tecnologias proporcionam, entre outras vantagens, precisão, acuidade e rapidez na documentação de gravuras rupestres, assim como de seu entorno paisagístico. Em última instância, o trabalho do arqueólogo é gerar modelos interpretativos do registro arqueológico, baseados em uma documentação o mais fiel possível para que esses modelos possam ser testados e revistos. As tecnologias de modelagem 3D elevam nossa capacidade a um novo patamar metodológico.
