In the last decade, Brazil was the scene of two of the world’s biggest disasters related to mining tailings dams. The collapse of the Mariana and Brumadinho dams was catastrophic event that brought to light major environmental and humanitarian crises. Facts like this incite debate on the safety of dam construction methods and highlight the need for a broad discussion of dam safety legislation in the country. From the above, this paper promotes a review of various forms of construction of tailings dams and their associated problems, as well as discusses the techniques for soil reinforcement and their construction methods. The work also brings an overview of the Brazilian dams from April to July 2019, tracing the context of the Brazilian tailings dams months after the tragedy of Brumadinho. The methodology includes a robust literature review and discourse analysis. In Brazil, the number of ruptured dams is alarming, especially in the state of Minas Gerais, in which more than 7 have broken in the last two decades. Among the damages, the deaths impact society abruptly and were cataloged 455 deaths, of which 216 correspond to the rupture of the dam of the Córrego do Feijão mine in Brumadinho. To evaluate and diagnose a dam, one should consider ordinance N ° 70,389, 2017 revoked by Resolution ANM n ° 95, of February 7, 2022. In this context, in March 2019, we experienced several disturbing situations regarding dam instability in the state of Minas Gerais, being categorized as risky structures. To exemplify, one can cite dams classified as level 2 risk that became level 3. Due to the above facts, several studies are being conducted to improve soil aspects. For example, we highlight the increase in soil resistance that can be done using commercial and alternative materials available in the environment.

This work aimed to evaluate the physical-chemical characteristics of pork from a local breed （Portuguese black pork called Preto Alentejano） and a commercial breed. Sixteen animals were used, 4 females and 4 males from each breed. Animals had 80-100 kg of live weight. The longissimus muscle between the 5th thoracic vertebra and the 10th lumbar vertebra was used in the analysis. Samples were analysed for protein, fat, pigments, ashes, dry mater, water-holding capacity, and texture. Results of fat and pigments contents indicate signiifcant （P〈0.05 and P〈0.01） differences for all treatments. For protein, ashes, dry mater, water-holding capacity and texture, no signiifcant differences were found for sex. In the analysis of fatty acids composition, ten were detected, being the main ones C16：0, C18：0, C16：1, C18：1, C18：2. There was a predominance of monounsaturated fatty acids （MUFA）, followed by saturated （SFA） and polyunsaturated （PUFA）. Differences were signiifcant for sex （P〈0.01） and breed （P〈0.01）. Preto Alentejano breed and females presented the higher percentages of SFA （P〈0.01） and MUFA （P〈0.001） fatty acids. Differences between breeds might be due to breed production system and feed differences.

Drainage and Preliminary Risk of Flooding in an Urban Zone of Eastern Amazon

引用

Journal of Geoscience and Environment Protection 2023年第5期11卷 1-16页

作者： Taís Silva Sousa Clezio Júnior teixeira Viegas Helenilza Ferreira Albuquerque Cunha alan Cavalcanti da Cunha Graduate Program in Environmental Sciences Federal University of Amapá Macapá Brazil Graduate Program in Tropical Biodiversity Federal University of Amapá Macapá Brazil Graduate Program in Biotechnology Federal University of Amapá Macapá Brazil

Drainage system is a poorly investigated basic sanitation and urban planning issue in the Amazon, which is often related to flooding processes and public health. The aim of the present research is to correlate Preliminary Risk of Flooding (PRF) to independent variables, based on the following methodology: 1) identifying and classifying risk areas by using the Geographic Information System (GIS) and 2) statistically correlating risk to sanitary and environmental variables. Results have shown that preliminary risk is correlated to, at least, seven sanitary and environmental variables, depending on flood influence area;and there are significant correlations observed in the rainy season interval [probability or significance (p) 0.05]. In conclusion, PRF is higher in the rainy season, but it is spatially influenced by the elevation of terrain, number of flooding points, drainage typology and Environmental Salubrity Index (ESI) of neighborhoods, which directly affect the water quality in nearby groundwater wells (Total Coliforms, nitrate (NO3) and ammonia (NH3)). However, this influence can eventually significantly change in the dry season.

Effect of Breed and Sex on Pork Meat Sensory Evaluation

Food and Nutrition Sciences 2014年第7期5卷 599-605页

作者： Sandra rodrigues Alfredo teixeira Mountain Research Centre(CIMO) Agrarian School of Polytechnic Institute of BragancaBragancaPortugal Veterinary and Animal Research Centre(CECAV)of University of Trás-os-Montes e Alto Douro Vila RealPortugal

This work had an objective to evaluate the sensory quality of two categories of pork meat from a commercial pork meat and a selected meat from the Portuguese black pork (Preto Alentejano breed). Sixteen animals were used, 8 females and 8 males from each breed. Animals had 80 - 100 kg of live weight. The longissimus muscle between the 5th thoracic vertebra and the 10th lumbar vertebra was used in the analysis. Sensory analysis was performed by a trained taste panel of 10 elements, in 5 sessions. All evaluation conditions were standardized, and the attributes studied were odor intensity, toughness, juiciness and flavor intensity. The taste panel found differences mainly between breeds. The panellists scored Preto Alentejano meat as being juicier, tenderer, and with richer taste than Commercial meat. The higher juiciness score of Preto Alentejano meat was probably attributable to the higher intramuscular fat content compared with Commercial meat. The Commercial pork was characterized mainly by high toughness.
