Highlights: [•] Different scenarios for energy recovery of MSW in Brazilian cities have been calculated and evaluated. [•] Two alternatives were analyzed to carry out the energy recovery from MSW: landfill biogas and Waste-to-Energy plant. [•] This study was based on urban centres using the MSW characteristics of the metropolitan region of Belo Horizonte. [•] This study also have been assessed the environmental impacts of the energy recovery from MSW using the LCA methodology. [•] Landfill as the worst MSW management option and the most promising option is the combustion of MSW for energy generation. [ABSTRACT FROM AUTHOR]

A retrospective study was performed in 100 dogs with 121 mandibular and 21 maxillary fractures. Dog fight (43.0 %) and automobile (12.0 %) trauma were the most common etiologies for fracture. The cause of fracture was unknown in 23.0 % of the cases, while pathologic fractures occurred in 13.0 % of cases. Young dogs (< 1-year-old) and dogs> 8-years of age were most affected. Mandibular fractures occurred in 90 dogs (90.0 %), with two dogs (2.2 %) having concurrent maxillary fractures. Maxillary fractures only were diagnosed in 10 dogs (10.0 %). The molar region (47.1 %) was the most commonly affected location for mandibular fracture,followed by fractures of the symphysis and parasymphysis (30.6 %), premolar region (17.4 %), angular process (4.1 %) and vertical ramus (0.8 %). In fractures of the mandibular region, the mandibular first molar tooth was often (85.9%) involved while the canine teeth were involved in 67.5 % of symphyseal and parasymphyseal fractures. The most common fracture of the maxilla was the maxillary bone (52.4 %), followed by the incisive (33.3 %), palatines (9.5 %), and nasal (4.8 %) bones. [ABSTRACT FROM AUTHOR]

Polycyclic aromatic hydrocarbons (PAHs) and the trophic structure of polychaete assemblages were studied in sediments at 28 stations in Todos os Santos Bay. Total PAH concentrations varied from 8 to 4163 ng g−1 dry weight. The indexes used for the determination of PAH origin suggested both pyrolytic and petrogenic sources. A total of 397 individuals of polychaetes was recorded which were classified in three trophic groups. The PCA ordination resulted in the formation of three groups of stations, Group I characterised by sandy sediments, low organic content, low total PAH concentration and percentage of potentially harmful PAH was dominated by subsurface deposit-feeders. The other two groups (IIa and IIb), showed similar percentages of silt and clay, however, Group IIb formed by those stations with high total organic carbon, total nitrogen, sulphur contents, high total PAH concentration and percentage of potentially harmful PAH was dominated by carnivores. Trophic changes could be explained by the level of exposure to PAH effects relative to differences in the life style and feeding strategies between deposit-feeders and carnivores.
