title: La Problemática de los Inmigrantes Ambientales y el Patrocinio Privado de Refugiados

description: Resumen El presente artículo tiene por objetivo analizar la política del Patrocinio Privado de Refugiados (Private Sponsorship of Refugees, en inglés), el cual se muestra como una alternativa para hacer frente a los flujos masivos de refugiados. El Patrocinio Privado de Refugiados, que nació en Canadá en la década de 1970, se basa en la participación del sector privado, no restricto a las empresas, sino también a la sociedad en general, la cual asume el patrocinio, o la responsabilidad de ayudar financieramente, a los solicitantes de refugio que desean refugiarse en el Estado de Destino, concientizando a la sociedad local sobre los sufrimientos y la realidad que enfrentan los solicitantes de refugio. En este sentido, el presente artículo analizará como el Patrocinio Privado de Refugiados puede dar una respuesta rápida frente al flujo de desplazados ambientales, dado que ellos no están encajados en la definición de refugiados en el Derecho Internacional.

title: Business Strategy and Environmental Practices: evidences on the sugar-alcohol sector

description: ABSTRACT This article aims at analyzing how companies that belong to the sugar-alcohol sector are dealing with environmental management under a strategic perspective. The research strategy chosen was the study of multiple cases undertaken in eight companies located in the states of Pernambuco and Paraíba. The main data gathering technique was the semi-structured interview. The analysis of data took place in two stages: individual analysis and crossed analysis of the cases. The results showed evidence that clients, society, competitors and governments are the main actors to influence companies, in the sense of making them rethink the consequences of their decisions under an environmental perspective. The formation of the strategy through the tool of planning was the most evidenced in the research. A theme that draws attention is that it was not found, in any of the companies studied, effective return measures for the environmental investments. Despite the commitment of the high administration with environmental matters supporting efforts in that direction, the environmental dimension seems to be relegated to specific functional levels, in a way that the alignment between operational and strategic issues is still incipient. Through the analysis of the main practices undertaken by the companies in the industrial sector, it is noticed that there still is a greater emphasis on corrective actions. However, there are growing efforts in favors of a pre-emptive behavior towards a strategic approach.

title: Aerodynamics of Harmonically Oscillating Aerofoil at Low Reynolds Number

description: ABSTRACT: Two-dimensional flows over harmonically oscillating symmetrical aerofoil at reduced frequency of 0.1 were investigated for a Reynolds number of 135,000, with focus on the unsteady aerodynamic forces, pressure and vortex dynamics at post-stall angles of attack. Numerical simulations using ANSYS® FLUENT CFD solver, validated by wind tunnel experiment, were performed to study the method of sliding mesh employed to control the wing oscillation. The transport of flow was solved using incompressible, unsteady Reynolds-Averaged Navier-Stokes equations. The 2-equation k-ε realizable turbulence model was used as turbulence closure. At large angle of attack, complex flows structure developed on the upper surface of the aerofoil induced vortex shedding from the activity of separated flows and interaction of the leading edge vortex with the trailing edge one. This interaction at some stage promotes the generation of lift force and delays the static stall. In this investigation, it was found that the sliding mesh method combined with the k-ε realizable turbulence model provides better aerodynamic loads predictions compared to the methods reported in literature.

title: Pattern of anxiety, insecurity, fear, panic and/or phobia observed by quantitative electroencephalography (QEEG)

description: Abstract Stress is a response in which an individual wants to have more control over a situation. A constant state of stress is called anxiety. Some patients deny symptoms. An instrument can help arrive at a diagnosis. Objective: Using TQ-7 QEEG, this study aimed to evaluate the association of symptoms of anxiety, insecurity, fear, panic and phobia with hot temporals defined as Beta (15-23 Hz) &gt;17% and High-Beta waves (23-38 Hz) &gt;10% at T3 and T4. Methods: Five hundred and forty-three patients of both genders with ages ranging from 16-59 years were evaluated, divided into two groups: Control (without hot temporals: n=274) and Case Group (with hot temporals: n=269). The Chi-square test was used (p-values ≤0.05). Results: There was a significant association (p-value &lt;0.001) between the symptoms related to amygdala activation, expressed in the temporals (Beta &gt;17% and High-Beta &gt;10%). (Anxiety, T3=89.6% - T4=88.8%; T3=92.6% - T4=93.3%), (Fear, T3=80.7% - T4=84.4%; T3=82.9% - T4=95.9%), (Insecurity, T3=82.2% - T4=81.4%; T3=69.5% - T4=97.8%), (Panic, T3=52.4 - T4=72.5%; T3=90.3% - T4=74.0%), (Phobia, T3=17.5% - T4=22.7%; T3=19.7% - T4=27.1%), when compared to the respective controls (Beta control, T3=8.4%, 10.2%, 21.2%, 1.1%, 0.4% and T4=11.3%, 4.4%, 23.0%, 2.6%, 1.1%) (High-Beta control, T3=4.0%, 6.9%, 6.2%, 0.4%, 0.0% and T4=17.5%, 6.2%, 3.3%, 4.0%, 0.7%). Conclusion: Anxiety, insecurity, fear, panic and phobia are observed by QEEG when the levels of total Beta &gt;17% and High-Beta waves &gt;10% at T3 and T4.

title: Systemic and translaminar action of neem oil for the control of Tuta absoluta (Meyrick) (Lep.: Gelechiidae) in tomato

description: The leaf miner Tuta absoluta (Meyrick) is the pest that mostly jeopardizes tomato production. The use of synthetic pesticides for its control can affect the crop economically and environmentally. As an alternative form of control, neem oil was applied on tomato leaves in order to assess antifeedant and insecticidal effects by systemic and translaminar action. In experiment for translaminar action, oil diluted in water was applied to the adaxial surface of leaflets at concentrations of 0.5, 1, 5 and 10%. The mortality rate ranged between 49 and 100%, and the average size of the mines, between 1.62 and 0.34 cm. In treatments represented by water and water + emulsifier (5%), mortality did not surpass 20%, with the average size of mines reaching 1.63 cm. The study of systemic action was performed by applying neem oil to the adaxial and abaxial surfaces of all leaves, except those that were infested by caterpillars. In this assay, the oil was applied at concentrations of 1, 2.5 and 5%, being diluted in water and emulsifiers. We observed that the mortality rate exceeded 90% when the oil was applied at concentrations of 2.5 and 5%, and the average size of mines was smaller than 1.0 cm. There was no mortality in the control treatments, but the mine size was on average 1.96 cm. Therefore, it is clear that the neem oil has an insecticidal and anti-food effect on T. absolutacaterpillars, and is possible to be incorporated and applied on tomato leaves.

title: The creation of municipalities and the formalization of metropolitan areas: federal coordination challenges

description: AbstractThis work aims to analyze the federal government actions on two topics related to the federative issue creation of municipalities and formalization of metropolitan areas. The goal was to understand the rationale underlying the federal government decisions in this field after the Constitution promulgation. The Union action between these poles demands analysis by its obvious implications in various public policies such as housing, sanitation, urban mobility, education, health and others. Among the studied elements, we emphasize the legislative proposals and institutional changes, whether it occurred or not. Events occurring in this little more than a quarter century, analyzed in accordance to the narrative method, show that the federal government has shown difficulty to coordinate this field. Omission is not rare, such as lack of attention by the federal executive to metropolitan and other urban areas and, on the other hand, central government levies disregarding the federation, such as the decision not to decide on national rules relating to the creation of new municipalities.

title: Social movements and mobilizations in Brazil: from 2013 to the present day

description: ABSTRACT This article deals with the conceptual difference between the mobilizations of the 21st century and the social movements of the last century, which are more perennial and structurally organized than the present ones. It analyzes the context and characteristics of the mobilizations of June 2013, the governmental reaction in that year and in 2014, the electoral process and the reaction of far-right mobilizations in 2015 and 2016. It concludes that the provisional and unstable relationship with the institutional field have made all mobilizations of this short period unfinished and with no visible political consequences regarding current political practices.

title: Functional morphology of subtropical tree seedlings in southern Brazil

description: Abstract The objective of this study was to analyze the morphofunctional attributes of Mixed Ombrophyllous Forest species of different successional categories. Fruits were collected from forest remnants in Curitiba, Paraná. It was analyzed the biometrics of seeds and seedlings of all species and the following ratios were estimated: shoot/seedling length, shoot/seedling mass, cotyledons/seedling mass, eophyll/seedling mass and seedling/ seed mass. Statistical differences among sucessional groups were observed in many of the evaluated traits. The variability among species is mainly explained by seedling size, tissue investment for light interception and shoot resource allocation. Late secondary species have larger seedlings with characteristics that indicate slower initial development, dependent on seed reserves. The pioneers species have smaller seedlings but faster development and earlier dependence on photosynthesis. These morphological and functional differences can result in different strategies for the establishment of seedlings in the successional process. The cluster analysis results on formation of two major groups. The first group is comprised of the late secondary species. The second group includes two distinct subgroups that separate the pioneers, and most of the early secondary species. These results indicate that the number and quality of available data should be considered in the definition of successional categories adopted in ecological studies.

title: Virulence of entomopathogenic nematodes (Rhabditida: Steinernematidae, Heterorhabditidae) to spittlebug Mahanarva spectabilis (Hemiptera: Cercopidae)

description: The spittlebug can seriously limit the production of forage, and the use of chemical products to control insect pests is costly and can harm the environment. Thus, there is a need to reduce the reliance on chemical agents by developing new strategies. The virulence of nine strains of entomopathogenic nematodes (EPNs) to spittlebugs was investigated under laboratory and greenhouse conditions. Fourth/fifth-instar nymphs of Mahanarva spectabilis were exposed to EPNs in the laboratory and the most virulent strains were applied on the nymphs in the greenhouse at concentrations of 2,000 and 4,000 EPNs/mL. The efficacy of the pathogenic agent was confirmed by the dissection of dead hosts. All the tested strains were pathogenic to the M. spectabilis nymphs in laboratory, particularly Steinernema carpocapsae, S. feltiae, S. riobraveand Heterorhabditis amazonensisRSC1, each of which caused nymph mortality higher than 80%. The concentration did not influence the efficiency of the strains, and those selected in the laboratory had similar efficiency in the greenhouse, except for S. carpocapsae, which was not as effective as the others. Entomopathogenic nematodes can be included in integrated pest management programs to M. spectabilis.

title: Oral and maxillofacial rehabilitation of a patient suffering from intraosseous adenoid cystic carcinoma

description: ABSTRACT Treatment of cancers of the head and neck may provoke sequelae that affect the quality of life of patients during and after treatment. Mouth-sinus communication resulting from partial or total surgical resection of the palate leads to the patient experiencing dysphagia, dysphonia and trismus, which can lead to social isolation of the individual. As a result, the work of the dental surgeon, together with the multidisciplinary team caring for cancer patients, is fundamental and can help with the diagnosis, assist in the management of chemotherapy and radiotherapy complications and enable postsurgical rehabilitation. The present study reports the case of a patient with adenoid cystic carcinoma in the right maxilla, who underwent a partial maxillectomy, the resulting sequela being mouth-sinus communication. The dental treatment was performed at the Hospital of the Federal University of Pelotas preoperatively, during and after treatment. At this time the patient is rehabilitated with an obturator prosthesis and is being monitored by the dental team and the head and neck surgeon.
