Effects of marginal vegetation removal on Odonata communities

OBJETIVOS: Com o intuito de avaliar os efeitos de mudanças na integridade ambiental sobre os indivíduos da comunidade de Odonata da sub-bacia do rio Borecaia, testamos a hipótese de que a riqueza de Anisoptera seria afetada positivamente pela remoção da vegetação; por outro lado, a riqueza Zygoptera seria prejudicada em virtude de suas necessidades ecofisiológicas; MÉTODOS: Selecionamos 10 riachos de ordens similares, seis classificados como preservados e quatro como alterados. Riachos classificados como preservados apresentaram valores do Índice valores de Integridade Habitat (HII) acima de 0.70 e mata continua nas duas margens com uma largura mínima de 70 metros. Cada ponto foi amostrado três vezes em dias diferentes. O efeito de remoção de vegetação sobre a riqueza foi avaliada utilizando Jackknife de primeira ordem; RESULTADOS: A diminuição da integridade física (mensurada com o IIH) dos córregos não exerceu efeito significativo sobre a riqueza estimada para a Ordem Odonata. Porém, a riqueza estimada de Anisoptera apresentou uma relação inversa com a integridade (r² = 0.485; p = 0.025), mostrando que com o aumento da integridade houve uma redução na sua riqueza de espécies; DISCUSSÃO: Como um padrão geral, Anisoptera apresenta maiores valores de riqueza em locais alterados; por outro lado, Zygoptera apresenta maiores valores em preservados. Devido suas restrições ecofisiologicas Odonata apresentou uma grande variação na sua composição e riqueza de espécie entre os dois tipos de ambientes, isso reforça o potencial da ordem em estudos de monitoramento ambiental e também mostra que Zygoptera será mais afetada pelas transformações de habitat. No entanto, futuros estudos incluindo mais amostras e diferentes córregos são necessários para confirmar este padrão sendo uma linha de pesquisa interessante para trabalhos futuros.

Application of carbon composite adsorbents prepared from coffee waste and clay for the removal of reactive dyes from aqueous solutions

A novel carbon composite was prepared from a mixture of coffee waste and clay with inorganic:organic ratio of 1.3 (CC-1.3). The mixture was pyrolysed at 700 °C. Considering the application of this adsorbent for removal of anionic dyes, the CC-1.3 was treated with a 6 mol L^-1 HCl for 24 h to obtain ACC-1.3. Fourier transform infrared (FTIR), N₂ adsorption/desorption curves, scanning electron microscope (SEM) and powder X-ray diffractometry (XRD) were used for characterisation of CC-1.3 and ACC-1.3 carbon adsorbents. The adsorbents were effectively utilised for removal of reactive blue 19 (RB-19) and reactive violet 5 (RV-5) textile dyes from aqueous solutions. The maximum amounts of RB-19 dye adsorbed at 25 °C are 63.59 (CC-1.3) and 110.6 mg g^-1 (ACC-1.3), and 54.34 (CC-1.3) and 94.32 mg g^-1 (ACC-1.3) for RV-5 dye. Four simulated dye-house effluents were used to test the application of the adsorbents for treatment of effluents.

Sagittal Mandibular Osteotomy for Removal of Intraosseous Lesion

The ramus sagittal split osteotomy or mandibular body is an established technique for correction of dentofacial deformities but can have an accurate indication in cases requiring surgical access to remove lesions or more teeth included in the region of the mandibular angle. The main advantages of this technique are the possibility of preservation of the inferior alveolar nerve bundle and significant reduction in postoperative morbidity. In this article, the authors show a case in which the sagittal osteotomy of the mandible was used to gain access for removal of a lesion (complex odontoma).

Maturity, Pulp Removal and Storage Effects on the Germination of Livistona rotundifolia Seeds

The Livistona rotundifolia species is native to Oceania, and has a high potential for landscaping use and as a pot plant. This work aimed to study the effects of the maturation stage, pulp removal and storage on the germination of L. rotundifolia seeds. The experimental design was entirely randomized in a factorial arrangement 5x2x2 (five storage periods: 15, 30, 45, 60 and 75 days; two maturation stages: green and ripe; and the presence or absence of the pulp - exocarp and mesocarp) with four replications of 25 seeds each. After sorting out the fruits by the maturity stage and removing the pulp out of half of the fruits from each plot, the seeds were placed in closed bottles, which were sealed and stored in a cold chamber at 10 degrees C. The seeds were removed from the cold chamber and left to germinate in plastic boxes (gerbox type) with sphagnum. The boxes were kept at 25-35 degrees C and photoperiod of 12 hours. The germination rate was determined when seed germination was steady. The highest germination rate was found when green fruits had their pulp removed. The germination rate gradually decreased with the increase of the storage period regardless the maturation stage and the presence or absence of the pulp.
