Imobilização de dióxido de titânio em malha de alumínio reciclado para a degradação de corante têxtil por Fotocatálise Heterogênea por Redes Neurais

In this work, aluminum net crafted (recycled) were used as TiO2 support for the treatment of textile dye Remazol golden yellow (RGY 150). The immobilization of 200mg of TiO2 was accomplished after aluminum net calcination. The following experiments were carried out in a photocatalytic bench reactor: preliminary tests, a 23 factorial experimental design with best system and the degradation kinetic in systems with TiO2 supported on aluminum net.It was observed characteristic peaks of aluminum and TiO2 (anatase and rutile) by XRD and the catalyst film formation was verified by SEM. The system UV/H2O2/TiO2 performed higher efficiency, with 99% of dye degradation in 50 minutes, followed by the system UV/H2O2/TiO2sp with 93% of dye degradation. Whereas the supported catalyst presents execution advantages and high degradation rates, the factorial design was realized for this system, displaying best degradation (100% degradation in 35 minutes). It was obtained k = 0.114 min-1 and R² = 0.994 in a pseudo-first-order model adjustment system. The use of artificial neural network was proven to be efficient to predict the degradation of a textile dye, with an absolute error of 0.0181. After treatment, there was a decrease of dye toxicity.Neste trabalho, redes de alumínio recicladas foram utilizadas como suporte de TiO2 para o tratamento do corante têxtil Remazol amarelo ouro (RGY 150). A imobilização de 100 mg de TiO2 foi realizada após calcinação do material de alumínio. Foram conduzidos em reator de bancada fotocatalítico testes preliminares, um experimento fatorial 23 com o melhor sistema e a cinética de degradação em sistemas com TiO2 suportado em rede de alumínio. Foram observados picos característicos de alumínio e TiO2 (anatase e rutilo) por DRX e a formação do filme catalítico foi verificada porMEV. O sistema UV/H2O2/TiO2 apresentou maior eficiência, com 99% de degradação do corante em 50 minutos, seguido do sistema UV/H2O2/TiO2sp com 93% de degradação do corante. Enquanto o catalisador suportado apresenta vantagens de execução e altas taxas de degradação, o planejamento fatorial foi realizado para este sistema, apresentando melhor degradação (100% de degradação em 35 minutos). Foi obtido k = 0,114 min-1 e R² = 0,994 em um sistema de ajuste de modelos de pseudo-primeira ordem. O uso da rede neural artificial mostrou-se eficiente para predizer a degradação de um corante têxtil, com erro absoluto de 0,0181. Após o tratamento, houve uma diminuição da toxicidade do corante

A inclusão escolar para pacientes com deficiência intelectual ou atraso cognitivo: School inclusion for patients with intellectual disability or cognitive delay

A educação inclusiva é fundamental para que crianças e adolescentes vivenciem ideias e experiências de ensino aprendizagem significativa, desenvolvam a autonomia e conquistem direitos de cidadania. No entanto, existem obstáculos que precisam ser compreendidos e superados e estratégias que podem ser adotadas para promover a inclusão de crianças com deficiência intelectual ou atraso cognitivo. Diante disso, este estudo tem como objetivo compreender o processo de inclusão escolar de alunos com deficiência intelectual ou atraso cognitivo. Para isso, trata-se de uma revisão sistemática de literatura, desenvolvida a partir da seleção de estudos nas bases de dados Scielo, Pubmed e BVS/Medline a partir do uso de descritores DeCS/MeSH e aplicação de critérios de inclusão e exclusão. Após a análise e interpretação dos dados, concluiu-se que, no processo de inclusão de alunos com deficiência intelectual ou atraso cognitivo no ambiente escolar, a educação inclusiva interfere positivamente na qualidade de vida desses. Para isso, destacam-se uma série de estratégias relevantes, tais como: envolvimento de escola como um todo, dos professores e da família; compreender a deficiência; valorizar os interesses e habilidades dos alunos com deficiência; estimular a autodeterminação desses e a convivência entre pessoas deficientes e não deficientes; promover a socialização por meio de jogos; utilizar atividades adaptadas; e cuidar da formação inicial e continuada dos professores, contemplando ideias sobre educação inclusiva

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.

NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics

Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used. We also request that users inform us of how they intend to use the data
