Emissão de CO2 em culturas de soja e arroz irrigado - Safra 2013/2014 - RS (CO2 emission in soybean cultures and irrigated rice – Crop 2013/2014 - RS)
Authors: Monteiro Gustavo Colepícolo 
Published: November 2017

A liberação de dióxido de carbono (CO2) do solo para a atmosfera é denominado “efluxo de CO2 do solo”, sendo uma fonte importante para o aumento de gases do efeito estufa. O principal objetivo desse trabalho é avaliar as diferentes emissões de CO2 para um sistema de rotação de cultura soja/arroz alagado, em cinco tratamentos distintos de manejo do solo realizado na Região agroecológica das Grandes Lagoas do Rio Grande do Sul, no campo experimental da Estação Experimental Terras Baixas da Embrapa Clima Temperadas, a fim de quantificar essas emissões sobre diferentes condições de temperatura do solo e temperatura do ar. Para realizar este trabalho, foram utilizados dados de cinco tratamentos em cultura de arroz alagado para se determinar a concentração de CO2 emitidos pelo solo e pela cultura de arroz irrigado em sistema de rotação de cultura. Os dados de concentração de CO2 foram coletados sempre da mesma maneira para os anos de 2013-2014, através do método da câmara estática fechada. A emissão de CO2 da cultura de arroz irrigado apresentou uma relação bem definida com a temperatura do solo e a temperatura do ar, sendo provavelmente as principais controladoras da emissão de CO2 da cultura. O manejo do solo mostrou-se forte influenciador das emissões de CO2 da cultura de arroz, porém são necessários mais estudos para verificar a real influência dessa prática. A B S T R A C TThe release of carbon dioxide (CO2) from the soil to the atmosphere is called ";;soil CO2 efflux";;, being an important source for the increase in greenhouse gases. The aim of this study is to evaluate the difference of CO2 emissions for a soybean / rice paddy rotation system in five different soil management treatments. These treatments were performed at the agro- ecological region of the Grandes Lagoas of Rio Grande do Sul, in the experimental field of the Experimental Station of Embrapa Clima Temperado, in order to quantify these emissions on different conditions, such as soil and air temperatures. To accomplish this work, data were used in five different treatments of flooded rice culture to determine the concentration of CO2 emitted by the soybean / rice paddy rotation system. The CO2 concentration data were collected in the same way for the year 2013- 2014, through the method of static closed chamber. The release of CO2 from the flooded rice crop had a well-defined relation with the soil and air temperature, being probably the main controller of the CO2 emission of the crop. Soil management has been showing a very well influence on the CO2 emissions of the rice crop, but more studies need to be done to verify the real influence of this practice.Keywords: greenhouse effect; soil management; culture rotation.

Este trabalho foi desenvolvido com o objetivo de realizar um diagnóstico ambiental da área de proteção do geossítio Minas do Camaquã, estado do Rio Grande do Sul, Brasil, a fim de compreender as características do sistema físico-ambiental e do processo de ocupação e uso da terra que contribuíram para a configuração das morfologias antropogênicas que constituem o patrimônio mineiro da área em questão. Os procedimentos metodológicos que possibilitaram atingir o objetivo foram: (1) levantamento e revisão de literaturas referentes às características do meio físico-ambiental da área de proteção aqui proposta; (2) levantamento de bibliografia especializada, para compreensão do processo histórico de ocupação do entorno das Minas do Camaquã; e (3) mapeamento das coberturas e usos da terra da área de proteção do geossítio Minas do Camaquã. Verificou-se a existência de um cenário com significativas intervenções resultantes do processo histórico de ocupação sobre a geodiversidade, onde o uso da terra foi determinante para a descaracterização da paisagem natural, sobretudo a partir da criação do relevo antropogênico, que pertence à geodiversidade da área e deve ser compreendido como patrimônio mineiro o que qualificou o Geossítio Minas do Camaquã como um geossítio da história da mineração. ABSTRACTThis work was carried out with the purpose of performing an environmental diagnosis of the Minas do Camaquã geosite protection area, state of Rio Grande do Sul, Brazil, in order to understand the characteristics of the physical-environmental system and the process of land use and occupation which contributed for the configuration of the anthropogenic morphologies that constitute the mining heritage of that area. The methodological procedures which enabled reaching the purpose were: (1) survey and review of literature referring to the physical-environmental characteristics of the protection area proposed here; (2) survey of specialized bibliography for the understanding of the historical process of occupation of the Minas do Camaquã surrounding; and (3) mapping of land uses and land covers of Minas do Camaquã geosite protection area. The existence of a scenario with significant interventions resulting from the historical process of occupation on the geodiversity was noticed, where the land use was a determining factor for the disfigurement natural landscape, especially from the creation of the anthropogenic terrain, which belongs to the area geodiversity and should be understood as a mining heritage which then qualified the Minas do Camaquã Geosite as a geosite of mining history. Key words: Occupation of space. Geodiversity. Environmental Analysis.

Published: November 2017

Introducción: el Sistema de Información Epidemiológica del Consumo de Drogas de Centros de Integración Juvenil integra datos de la población que solicita tratamiento en las 116 unidades que conforman la red nacional de atención.

Objetivo: el presente trabajo compara las características sociodemográficas y de consumo en usuarios de drogas solicitantes de tratamiento ambulatorio entre 2007 y 2014.

Método: se recuperó información de cerca de 170 mil casos, principalmente de población atendida entre 2007 y 2014 (n=18,136 y 21,320, respectivamente). El análisis comprendió la descripción de tendencias del consumo 2007-2014 en un nivel nacional; la comparación del perfil sociodemográfico y el patrón de consumo de la población atendida en este periodo; así como la comparación regional del uso reciente de sustancias y de su crecimiento medio anual.

Resultados: se observa un aumento significativo del consumo de mariguana, metanfetaminas, alucinógenos y éxtasis, mientras que el uso de cocaína, inhalables y heroína presenta una disminución. Se registra un incremento de mujeres y menores de edad atendidos, una menor edad de inicio y un aumento del consumo de mariguana como droga de inicio y de mayor impacto. Finalmente, se aprecian diversas diferencias regionales.

Discusión y conclusiones: los resultados confirman lo reportado en encuestas de México respecto al aumento del uso de mariguana y metanfetaminas, así como la disminución del uso de cocaína, inhalables y heroína, contrario a lo reportado en otras poblaciones. Estos hallazgos proporcionan información relevante para el desarrollo de programas y servicios en México.

Introducción: las creencias adictivas constituyen un riesgo para el uso de sustancias; contribuyen a mantener el consumo y proporcionan un trasfondo para la recaída. En la actualidad existen cuestionarios que miden creencias relacionadas con el consumo de sustancias de manera global, pero ninguno está enfocado en evaluar creencias adictivas en fumadores; hacerlo apoyaría en el manejo clínico de las personas que buscan dejar de fumar.

Objetivo: evaluar la estructura factorial de un cuestionario que mide creencias adictivas en fumadores.

Método: mediante un muestreo intencional se obtuvo una muestra de 300 jóvenes fumadores mayores de 18 años. Todos los participantes respondieron un cuestionario de autorreporte compuesto por 60 ítems que exploran creencias relacionadas con el consumo de tabaco. Se realizó un análisis factorial confirmatorio (AFC) para determinar el modelo con un ajuste adecuado.

Resultados: luego de evaluar dos modelos con AFC, se seleccionó uno de tres factores con una carga cruzada, cuyas medidas de bondad de ajuste fueron X2 S-B (22) = 38.37, p = .01, X2 S-B / gl = 1.74. CFIS = .978 RMSEAS = .050 (IC 90% .021–.076), que indican un ajuste adecuado de los datos.

Discusión y conclusiones: la estructura factorial del CCAF está asociada con las creencias adictivas descritas por Beck. El CCAF es una herramienta breve que podría coadyuvar en el tratamiento de personas que buscan dejar de fumar.

La educación no es un servicio como el que brinda un hotel de 5 estrellas, porque un estudiante no siempre logra obtener lo que él o ella quiere (usualmente buenas calificaciones), debido a que no basta solamente con ir a clases o pagar una matrícula, adicionalmente estas personas deberán dar tiempo, dedicación y esfuerzo, aspectos por el que se diferencia del resto de bienes y servicios que se ofertan. Por esta razón, entre otras, hay opiniones opuestas sobre cómo los alumnos deben ser tratados en una universidad, sin embargo, ellos siguen siendo usuarios de un servicio, por tanto, deben ser satisfechos sus requerimientos. En consecuencia, el estudiante podrá ser tratado como “cliente, consumidor o coproductor, la verdad no importa como sea llamado, siempre y cuando alguien se preocupe por ellos” (Redding, 2005). Consecuentemente, el objetivo general de este estudio es el de realizar un análisis de los principales factores que influyan en la satisfacción de los estudiantes, con el propósito de contribuir al conocimiento que las universidades deberían tener sobre ellos. Para lo cual el alcance de la investigación se centra sólo en los factores más controlables por una universidad, a través de una revisión documental en la que se analizó una gran cantidad de aportes realizados sobre la satisfacción estudiantil por investigadores a nivel global, con el fin de alcanzar un estudio incluyente con carácter internacional.

OBJECTIVEDecompressive craniectomy (DC) is a widely used procedure in neurosurgery; however, few studies focus on the best surgical technique for the procedure. The authors’ objective was to conduct a prospective randomized controlled trial comparing 2 techniques for performing DC: with watertight duraplasty and without watertight duraplasty (rapid-closure DC).METHODSThe study population comprised patients ranging in age from 18 to 60 years who were admitted to the Neurotrauma Service of the Hospital da Restauração with a clinical indication for unilateral decompressive craniectomy. Patients were randomized by numbered envelopes into 2 groups: with watertight duraplasty (control group) and without watertight duraplasty (test group). After unilateral DC was completed, watertight duraplasty was performed in the control group, while in the test group, no watertight duraplasty was performed and the exposed parenchyma was covered with Surgicel and the remaining dura mater. Patients were then monitored daily from the date of surgery until hospital discharge or death. The primary end point was the incidence of surgical complications (CSF leak, wound infection, brain abscess, or subgaleal fluid collections). The following were analyzed as secondary end points: clinical outcome (analyzed using the Glasgow Outcome Scale [GOS]), surgical time, and hospital costs.RESULTSFifty-eight patients were enrolled, 29 in each group. Three patients were excluded, leaving 27 in the test group and 28 in the control group. There were no significant differences between groups regarding age, Glasgow Coma Scale score at the time of surgery, GOS score, and number of postoperative follow-up days. There were 9 surgical complications (5 in the control group and 4 in the test group), with no significant differences between the groups. The mean surgical time in the control group was 132 minutes, while in the test group the average surgical time was 101 minutes, a difference of 31 minutes (p = 0.001). The mean reduction in total cost was $420.00 USD (a 23.4% reduction) per procedure in the test group.CONCLUSIONSRapid-closure DC without watertight duraplasty is a safe procedure. It is not associated with a higher incidence of surgical complications (CSF leak, wound infection, brain abscess, or subgaleal fluid collections), and it decreased surgical time by 31 minutes on average. There was also a hospital cost reduction of $420.00 USD (23.4% reduction) per procedure.Clinical trial registration no.: NCT02594137 (clinicaltrials.gov)

Abstract
We introduce a method for modeling disk galaxies designed to take full advantage of data from integral field spectroscopy (IFS). The method fits equilibrium models to simultaneously reproduce the surface brightness, rotation, and velocity dispersion profiles of a galaxy. The models are fully self-consistent 6D distribution functions for a galaxy with a Sérsic profile stellar bulge, exponential disk, and parametric dark-matter halo, generated by an updated version of GalactICS. By creating realistic flux-weighted maps of the kinematic moments (flux, mean velocity, and dispersion), we simultaneously fit photometric and spectroscopic data using both maximum-likelihood and Bayesian (MCMC) techniques. We apply the method to a GAMA spiral galaxy (G79635) with kinematics from the SAMI Galaxy Survey and deep g- and r-band photometry from the VST-KiDS survey, comparing parameter constraints with those from traditional 2D bulge–disk decomposition. Our method returns broadly consistent results for shared parameters while constraining the mass-to-light ratios of stellar components and reproducing the H i-inferred circular velocity well beyond the limits of the SAMI data. Although the method is tailored for fitting integral field kinematic data, it can use other dynamical constraints like central fiber dispersions and H i circular velocities, and is well-suited for modeling galaxies with a combination of deep imaging and H i and/or optical spectra (resolved or otherwise). Our implementation (MagRite) is computationally efficient and can generate well-resolved models and kinematic maps in under a minute on modern processors.

Abstract
Multiwavelength surveys covering large sky volumes are necessary to obtain an accurate census of rare objects such as high-luminosity and/or high-redshift active galactic nuclei (AGNs). Stripe 82X is a 31.3 X-ray survey with Chandra and XMM-Newton observations overlapping the legacy Sloan Digital Sky Survey Stripe 82 field, which has a rich investment of multiwavelength coverage from the ultraviolet to the radio. The wide-area nature of this survey presents new challenges for photometric redshifts for AGNs compared to previous work on narrow-deep fields because it probes different populations of objects that need to be identified and represented in the library of templates. Here we present an updated X-ray plus multiwavelength matched catalog, including Spitzer counterparts, and estimated photometric redshifts for 5961 (96% of a total of 6181) X-ray sources that have a normalized median absolute deviation,

, and an outlier fraction, η = 13.7%. The populations found in this survey and the template libraries used for photometric redshifts provide important guiding principles for upcoming large-area surveys such as eROSITA and 3XMM (in X-ray) and the Large Synoptic Survey Telescope (optical).

Abstract
We report on a search for optical pulsation from M82 X-2 over a range of periods. M82 X-2 is an X-ray pulsar with a 1.37s average spin period and a 2.5 day sinusoidal modulation. The observations were done with the ARray Camera for Optical to Near-IR Spectrophotometry at the 200 inch Hale telescope at the Palomar Observatory. We performed H test and χ
2 statistical analysis. No significant optical pulsations were found in the wavelength range of 3000–11000 Å with a pulsation period between 1.36262 and 1.37462 s. We found an upper limit on pulsed emission in the 4000–8000 Å wavelength range to be fainter than ∼20.5 mag

Galectin-1: A Jack-of-All-Trades in the Resolution of Acute and Chronic Inflammation
Authors: Sundblad Victoria , Morosi Luciano G. , Geffner Jorge R. , Rabinovich Gabriel A. 
Published: November 2017

AbstractRegulatory signals provide negative input to immunological networks promoting resolution of acute and chronic inflammation. Galectin-1 (Gal-1), a member of a family of evolutionarily conserved glycan-binding proteins, displays broad anti-inflammatory and proresolving activities by targeting multiple immune cell types. Within the innate immune compartment, Gal-1 acts as a resolution-associated molecular pattern by counteracting the synthesis of proinflammatory cytokines, inhibiting neutrophil trafficking, targeting eosinophil migration and survival, and suppressing mast cell degranulation. Likewise, this lectin controls T cell and B cell compartments by modulating receptor clustering and signaling, thus serving as a negative-regulatory checkpoint that reprograms cellular activation, differentiation, and survival. In this review, we discuss the central role of Gal-1 in regulatory programs operating during acute inflammation, autoimmune diseases, allergic inflammation, pregnancy, cancer, and infection. Therapeutic strategies aimed at targeting Gal-1–glycan interactions will contribute to overcome cancer immunosuppression and reinforce antimicrobial immunity, whereas stimulation of Gal-1–driven immunoregulatory circuits will help to mitigate exuberant inflammation.
