Saberes elementares matemáticos em provas de concursos (Sergipe 1874 a 1899)

Disponível em: http://seer.ufms.br/index.php/pedmat/search/titles?searchPage=7Neste artigo é apresentado o resultado de uma pesquisa em que foram utilizadas como fontes, provas de concursos para professores primários do magistério público de Sergipe e as prescrições das matérias para o ensino primário constantes nos Regulamentos de Ensino relativas a cada período, de 1874 a 1899, com o objetivo de identificar, se, e como os saberes elementares matemáticos estavam relacionados com as prescrições postas na legislação. Nas provas com formatos diferentes, dissertativas ou de resolução, procuramos verificar aproximações e/ou distanciamentos entre elas e o que era prescrito pela legislação ao ensino primário. Foi possível identificar saberes elementares matemáticos a exemplo de operações fundamentais com inteiros, quebrados e frações, redução e conversão de medidas, entre outros. Além disso, foi possível identificar referências aos métodos individual, mútuo, simultâneo e misto para organização das aulas

Persistent effects of musical training on mathematical skills of children with developmental dyscalculia

Musical training (MT) is perceived as a multi-sensory program that simultaneously integrates visual, aural, oral, and kinesthetic senses. Furthermore, MT stimulates cognitive functions in a ludic way instead of tapping straight into the traditional context of school learning, including mathematics. Nevertheless, the efficacy of MT over mathematics remains understudied, especially concerning longstanding effects. For this reason, this longitudinal study explored the impact of MT on numerical cognition and abstract visual reasoning using a double-blind and quasi-experimental design. We assessed two groups of children from primary schools, namely one with developmental dyscalculia [DD; n = 22] and another comprising typically developing children [TD; n = 22], who concomitantly underwent MT. Numerical cognition measurement was carried out at four different time points: Baseline (pre-MT assessment), mid-test (after 7 weeks of MT), post-test (after 14 weeks of MT), and follow-up (10 weeks after the end of MT). Significant interactions were found between time and group for numerical cognition performance, in which the DD group showed higher scores in number comprehension, number production at mid-test, and calculation at post-test compared to baseline. A key finding was that number production, number comprehension, and calculation effects were time-resistant for the DD group since changes remained on follow-up. Moreover, no significant differences over time were found for abstract visual reasoning for both groups. In conclusion, the findings of this study showed that MT appears to be a useful tool for compensatory remediation of DD.info:eu-repo/semantics/publishedVersio

Before the flood:Miocene otoliths from eastern Amazon Pirabas Formation reveal a Caribbean-type fish fauna

AbstractThe Pirabas Formation of Early Miocene age represents the final stage of the central western Atlantic carbonate platform in northeastern South America, predating the emplacement of the Amazon delta system. The otolith-based fossil fish fauna is represented by 38 species typical of a shallow marine environment. A total of 18 species are described new to science from the families Congridae, Batrachoididae, Bythitidae, Sciaenidae and Paralichthyidae. The fish fauna was associated with high benthic and planktic primary productivity including seagrass meadows, calcareous algae and suspension-feeders. The break of todays shallow marine bioprovince at the Amazonas delta mouth is not evident from the fish fauna of the Pirabas Fm., which shows good correlation with the Gatunian/proto-Caribbean bioprovince known from an only slightly younger time window in Trinidad and Venezuela. Differences observed to those Early Miocene faunal associations are interpreted to be mainly due to stratigraphic and geographic and not environmental differences. We postulate that the emergence of the Amazonas river mouth close to its present day location has terminated the carbonate cycle of the Pirabas Fm. and pushed back northwards a certain proportion of the fish fauna here described

Recuperação da amônia removida por processo de air stripping aplicado ao tratamento de lixiviados de aterro sanitário: estudo em escala piloto

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-Graduação em Engenharia Ambiental, Florianópolis, 2011Altas concentrações de nitrogênio amoniacal presente nos lixiviados de aterro sanitário podem causar impactos ambientais e à saúde pública. O objetivo deste trabalho foi a remoção de amônia de lixiviado de aterro sanitário pelo processo de air stripping (arraste com ar) e sua recuperação através de absorção em solução ácida. Para issoq foi utilizada uma torre de PVC com 150 mm de diâmetro e 1,95 m de altura útil recheada com anéis tipo "raschig" de 5 cm de comprimento e 2,5 cm de diâmetro. As vazões de lixiviado testadas foram de 9, 18, 20 e 40 L/h, e as vazões de ar foram de 1.800 e 3.600 L/h. As relações entre vazão de ar e vazão de lixiviado foram de 200, 90 e 45. Também foram testados alguns produtos químicos para promover a alcalinização do lixiviado antes do processo de air stripping: hidróxido de cálcio padrão analítico; cal hidratada comercial tipo CHIII e hidróxido de sódio padrão analítico. Para recuperar a amônia foram usados 3 frascos lavadores, de vidro, contendo 2,5 L de solução de ácido fosfórico, com concentrações de 0,12 e 0,24 mol/L. Para as condições avaliadas neste trabalho, foram necessários de 9 a 21 m3 ar para cada grama de nitrogênio amoniacal removido. Os resultados mostraram que é possível remover todo o nitrogênio amoniacal do lixiviado usando air stripping. Além disso, a amônia pode ser recuperada em até 92% utilizando ácido fosfórico, gerando-se assim o fosfato de amônio

Destarte, o objetivo principal deste trabalho é investigar se há ações de transição na Rede Municipal de Ensino de Curitiba e compreender a importância deste processo, refletindo sobre as especificidades das crianças e suas singularidades, visto que, no processo de transição da criança, se faz necessário estabelecer ações que precisam ser contínuas da Educação Infantil, na qual possuem necessidades diferentes que precisam estar presentes nos primeiros anos do Ensino Fundamental para que não haja a ruptura do processo de ensino aprendizagem. A metodologia utilizada foi aanálise de referenciais teóricos, documentos oficiais sobre a Educação Básica e pesquisa de campo sobre a temática estudada, realizada por meio de entrevista com pedagogas de uma escola municipal de Curitiba e de um Centro Municipal de Educação Infantil (CMEI) próximo. A verificação dos documentos oficiais deu o aparato no desenvolvimento do trabalho, além do aporte teórico para a realização da análise das práticas educativas, partindo de estudos de autores como Corsaro (2011), Kramer (2006), Moss (2011), Neves; Gouvêa; Castanheira (2011), Postaman (199), Sarmento (2004), Vygotsky (1998), Zabalza (1998) e Zanluch (2005), que trazem aspectos relevantes ao se pensar no processo de transição da educação infantil para o ensino fundamental. A necessidade de realizar uma entrevista com as pedagogas advém das pesquisas realizadas e da investigação em documentos oficiais, a fim de discutir as possibilidades de práticas educativas desenvolvidas nas escolas e nos CMEIs da Rede Municipal de Ensino de Curitiba (RME). Concluímos com este trabalho que, é importante que gestores/as, pedagogos/as, professores/as considerem as dificuldades e singularidades das crianças durante esse processo, de modo a não considerar somente a demanda curricular, mas também promover momentos de maior interação com suas crianças em diferentes tempos e espaços, refletindo sobre suas práticas educativasAbstract: This Course Conclusion Paper addresses the importance of reflecting on educational practices in the transition process of preschool children to the 1st year of elementary school. Thus, the main objective of this work is to investigate whether there are transition actions in the Municipal Education Network of Curitiba and to understand the importance of this process, reflecting on the specificities of children and their singularities, since, in the child's transition process, it takes place. It is necessary to establish actions that need to be continuous in Early Childhood Education, in which they have specific needs that need to be present in the first years of Elementary School so that there is no disruption of the teaching-learning process.The methodology used was the analysis of theoretical references, official documents on Basic Education and field research on the subject studied, carried out through interviews with pedagogues from a municipal school in Curitiba and a nearby Municipal Center for Early Childhood Education (CMEI) . The verification of official documents provided the apparatus for the development of the work, in addition to the theoretical support for carrying out the analysis of educational practices, based on studies by authors such as Corsaro (2011), Kramer (2006), Moss (2011), Neves; Gouvea; Castanheira (2011), Postaman (199), Sarmento (2004), Vygotsky (1998), Zabalza (1998) and Zanluch (2005), which bring relevant aspects when thinking about the transition process from early childhood education to elementary education. The need to conduct an interview with pedagogues comes from the research carried out and from the investigation of official documents, in order to discuss possibilities for educational practices developed in schools and in CMEIs of the Municipal Education Network of Curitiba (RME).We conclude with this work that it is important that managers/as, pedagogues/as, teachers/as considered as difficulties and singularities of children during this process, in order not only to consider the curricular demand, but also to promote moments of greater interaction with their children in different times and spaces, reflecting on their educational practice

Forensic Genetics as a Tool for Peace and Justice: An Overview on DNA Quantification

In Forensic Genetics, DNA analysis is performed to obtain a Short Tandem Repeat (STR) profile from an evidence sample, which is then compared with the victim and suspect(s) reference sample STR profile, to determine their contribution to that evidence sample. However, forensic biological samples can be present in low quantities and be exposed to different environmental insults leading to DNA degradation and contamination by inhibitor compounds. Thus, it is desirable for a forensic scientist to have useful information about the forensic sample quantity and quality prior to STR amplification. New methods in Forensic DNA analysis for detecting, preserving, and quantifying DNA, as well as its recovery from different biological materials are continually being developed. Real-Time PCR (RT-PCR) assays for DNA quantification, like the recent Quantifiler® Duo DNA quantification kit (Applied Biosystems) proved to be very useful in forensic samples. Since many samples, mainly those resulting from sexual assault cases are often composed by unbalanced male/female DNA mixtures, the knew RT-PCR quantification assay, developed to quantify relative male/ female DNA ratio contributes not only to total DNA determination but also to ascertain the presence and quantity of enough male DNA in the sample. These results are important to guide the optimal STR analysis selection, such as autosomal STR, Y-STR, or mini-STR, increasing downstream analysis success rates. In this work we present real forensic casework where the DNA amount and quality were important to guide the selection of the appropriate STR amplification kit in order to increase the success of profiling in the first attempt, reducing the number of samples that need to be reprocessed and thereby decreasing the turn around time in a forensic laboratory.info:eu-repo/semantics/publishedVersio

ICB Nutrisolo Trichoderma® as growth promoter in soybean crops

Soybean is the most important crop in the world due to growing external demand. Nevertheless, its production requires a high use of pesticides. Trichoderma is a fungal genus with the potential to promote plant growth because of its broad metabolic arsenal. Because it increases efficiency in several cultures, Trichoderma spp. have the potential to be used as an alternative to chemicals. Given this context, this study aimed to evaluate the performance of the ICB Nutrisolo Trichoderma® inoculant on parameters related to soybean growth and production. Crops with five different soil and climate conditions were evaluated in Rio Grande do Sul State (southern Brazil) using parameters such as average plant height, average plant population, average number of grains/pod, number of pods/plant average, and average weight of one thousand grains, which revealed the results of productivity. The ICB Nutrisolo Trichoderma® increased plant height, number of pods, and grain weight, consequently increasing productivity in soybean plants. In this way, it was possible to characterize the product ICB Nutrisolo Trichoderma® as a growth-promoting inoculant for the soybean crop, increasing the scope of product registration
