Metropolização, segregação socioespacial e injustiça ambiental: o caso da Baía de Sepetiba, RJ

A metropolização do espaço refere-se a um conjunto de processos que abrange grandes dimensões urbanas, caracterizados principalmente pelas transformações do sistema productivo, o que acaba por desconstruir relações que, anteriormente, eram majoritariamente rurais. Os processos de metropolização acabam por exercer, desta forma, o papel de produtores de segregação socioespacial, o que gera injustiças ambientais, uma vez que resulta na concentração de ônus decorrentes da poluição e degradação do ambiente em territorios caracterizados por condições socioeconômicas mais vulneráveis, sendo os territrios  que recebem os enpreendimentos danosos ao ambiente chamados zonas de sacrifício. Esses processos configuram conflitos entre os detentores do capital e as comunidades locais que sofrem com a poluição e que precisam do ambiente como fonte de sobrevivência física e simbólica. Neste contexto, o artigo tem por objetivo investigar os conflitos envolvendo a TKSCA e as populações do entorno de Baía de Sepetiba pela perpetiva da justiça ambiental, procurando investigar se existem processos de injustiça ambiental no territorio associados à instalação da indústria siderúrgica. Os processos de injustiça foram confirmados através do estudio de conceitos relacionados à justiça ambiental, visitas de campo, levantamento bibliográfico, análise e discussão de variáveis socioeconômicas e ambientais obtidas a partir dos dados do censo demográfico do ano de 2010, e mapeamento da área de estudo através da ferramenta ArcGIS 10.1

Characterization, physicochemical stability, and evaluation of in vitro digestibility of solid lipid microparticles produced with palm kernel oil and tristearin

Solid lipid particles have been investigated by food researchers due to their ability to enhance the incorporation and bioavailability of lipophilic bioactives in aqueous formulations. The objectives of this study were to evaluate the physicochemical stability and digestibility of lipid microparticles produced with tristearin and palm kernel oil. The motivation for conducting this study was the fact that mixing lipids can prevent the expulsion of the bioactive from the lipid core and enhance the digestibility of lipid structures. The lipid microparticles containing different palm kernel oil contents were stable after 60 days of storage according to the particle size and zeta potential data. Their calorimetric behavior indicated that they were composed of a very heterogeneous lipid matrix. Lipid microparticles were stable under various conditions of ionic strength, sugar concentration, temperature, and pH. Digestibility assays indicated no differences in the release of free fatty acids, which was approximately 30% in all analises. The in vitro digestibility tests showed that the amount of palm kernel in the particles did not affect the percentage of lipolysis, probably due to the high amount of surfactants used and/or the solid state of the microparticles.The authors are grateful to the FAPESP and CNPq for the scholarships granted (J.C.S., FAPESP fellowships 2010/13229-8 and 2012/02316-2, and T.

Porous ceramic supported TiO2 nanoparticles : enhanced photocatalytic activity for Rhodamine B degradation

Photocatalytic processes are an efficient and important technique to mineralize organic contaminants in aqueous effluents. However, it is paramount that there is a way to recover the catalyst after degradation. Based on this problem, this research seeks to evaluate the photocatalytic properties of TiO2 under porous ceramics support for the degradation of Rhodamine B (RhB). TiO2 was synthesized by sol-gel, dried at 100 ◦C and calcined at 400 ◦C. The morphological, optical and structural proprieties of the particles were characterized. The XRD patterns of samples calcined at 400 ◦C showed only the anatase phase, confirmed by Raman. Not heat-treated xerogel was amorphous. The agglomerates are composed of fine particles, in the nanometric scale of 15nm. The bandgap of the powder is 3.21 eV, and the surface area is 60.1m2 g−1. To evaluate its photocatalytic activity, the anatase TiO2 was supported in a porous ceramic substrate by a dip-coating process. The heterogeneous photocatalysis showed excellent results, with the degradation of up to 83% of RhB. It was possible obtained with successful an efficient technique for the treatment of wastewater with Anatase nanoparticles supported in the ceramic support obtained from of reuse of the residues.Los procesos fotocatalíticos son técnicas eficientes para la mineralización de contaminantes orgánicos en efluentes acuosos. Sin embargo, es fundamental que haya una forma de recuperar el catalizador después de la degradación. En base a este problema, esta investigación busca evaluar las propiedades fotocatalíticas del dióxido de titanio (TiO2) bajo el soporte de cerámica porosa para la degradación de la rodamina B (RhB). El TiO2 se sintetizó mediante sol-gel, se secó a 100 ◦C y se calcinó a 400 ◦C. Se caracterizaron las propiedades morfológicas, ópticas y estructurales de las partículas. Los patrones DRX de las muestras calcinadas a 400 ◦C mostraron solo la fase anatasa, confirmada por Raman. El xerogel no tratado térmicamente era amorfo. Los aglomerados están compuestos de partículas finas, en la escala de 15nm. El intervalo de banda es de 3,21 eV, y el área de superficie es de 60,1m2.g−1. Para evaluar la actividad fotocatalítica, se recubrió un sustrato cerámico poroso mediante el proceso de recubrimiento por inmersión. La fotocatálisis heterogénea mostró excelentes resultados, con la degradación de hasta el 83% de la RhB. Fue posible obtener con éxito una técnica eficiente para el tratamiento de aguas residuales con nanopartículas de anatasa soportadas en el soporte cerámico obtenido de la reutilización de los residuos

Uso da radiação UV-C na qualidade pós-colheita de tangerina ‘ponkan’

O objetivo do trabalho foi avaliar o comportamento pós-colheita dos frutos de tangerina ‘Ponkan’ sob a exposição à radiação UV-C. Os frutos desse estudo foram adquiridos em um Centro de Comercialização da Cidade de Anapólis. O delineamento experimental utilizado no ensaio foi o inteiramente casualizado em esquema fatorial 4 x 5, quatro tempos de exposição à UV-C (0 minutos, 1 minuto, 2 minutos e 3 minutos) e cinco dias de armazenamento (0, 4, 8, 12 e 16), com quatro repetições. As maiores perdas de massa foram analisadas nos frutos tratados com radiação UV-C. As variáveis pH, sólidos solúveis totais e acidez titulável não foram influenciadas pela exposição à radiação UV-C. A radiação em tangerina ainda carece de estudos, no que diz respeito ao comportamento pós-colheita dos frutos frente à exposição da UV-C.Thus, the objective of this work was to evaluate the post-harvest behavior of 'Ponkan' tangerine fruits under exposure to UV-C radiation. The fruits of this study were acquired in a Commercialization Center in the City of Anapólis. The experimental design used in the experiment was completely randomized in a 4 x 5 factorial scheme, four times of exposure to UV-C (0 minutes, 1 minute, 2 minutes and 3 minutes) and five days of storage (0, 4, 8, 12 and 16), with four repetitions. The highest mass losses were analyzed in fruits treated with UV-C radiation. The variables pH, total soluble solids and titratable acidity were not influenced by exposure to UV-C radiation. The radiation in tangerine still lacks studies, with regard to the post-harvest behavior of the fruits in the face of UV-C exposure

Position of lingual foramina in cone beam computed tomography and its implications for choosing the dimensions of dental implants for mandibular symphysis

ABSTRACT Objective: To identify the lingual foramina in a Brazilian population of 210 individuals through Cone-Beam Computed Tomography images, in order to guide the installation of dental implants in the region of the mental symphysis. Methods: After identifying the lingual foramina on a parasagittal section, four measurements were taken: distance to the alveolar ridge, distance to the mandibular lower border, distance to the limit of the vestibular cortical, and alveolar ridge inclination angle. The measurements were compared in relation to gender by the Mann-Whitney test. The association between gender and the number of foramina was done by the chi-square test. Pearson’s correlation analyzed the linear relationship between age and number of foramina. Results: Lingual foramina are present in 99.6% of the research participants. In the upper-inferior direction, a mean distance to the alveolar ridge of 21.4 mm was noted, while the mean distance to the lower mandibular border was 13.1 mm. In the bucco-lingual direction, a mean distance from the lingual foramina to the vestibular cortical of 15.2 mm is noted. The inclination angle of the alveolar ridge had a mean of 25.4º. Regarding gender, the test was not significant only for the distance to the vestibular cortical. Conclusion: The lingual foramina had a descending way in 100% of cases, being positioned mainly in the middle thirds (66.5%) and lower thirds (32.7%) of the mandibular ridge height. The use of dental implants up to 13 mm in length and up to 4 mm in diameter in the region of the symphysis mentualis is recommended

Rapid reduction of herbicide susceptibility in junglerice by recurrent selection with sublethal dose of herbicides and heat stress

Global climate change, specifically rising temperature, can alter the molecular physiology of weedy plants. These changes affect herbicide efficacy and weed management. This research aimed to investigate the combined effect of heat stress (HS) and sublethal doses of herbicides (four active ingredients) on adaptive gene expression and efficacy of herbicide on Echinochloa colona (L.) Link (junglerice). Three factors were evaluated; factor A was E. colona generation (G0-original population from susceptible standard; G1 and G2 were progenies of recurrent selection), factor B was herbicide treatment (florpyrauxifen-benzyl, glufosinate-ammonium, imazethapyr, quinclorac and nontreated check) and factor C was HS (30 and 45 ◦C). The herbicides were applied at 0.125× the recommended dose. Recurrent exposure to HS, combined with sublethal doses of herbicides, favors the selection of plants less susceptible to the herbicide. Upregulation of defense (antioxidant) genes (APX: Ascorbate peroxidase), herbicide detoxification genes (CYP450 family: Cytochrome P450), stress acclimation genes (HSP: Heat shock protein, TPP: Trehalose phosphate phosphatase and TPS: Trehalose phosphate synthase) and genes related to herbicide conjugation (UGT: UDP Glucosyltransferase) was significant. The positive regulation of these genes may promote increased tolerance of E. colona to these herbicides
