Higher education, stakeholders and collaborative work for entrepreneurial learning

Institutions of Higher Education can provide, in their internal environment, entrepreneurial learning opportunities for students stimulating new attitudes and behaviours towards entrepreneurship. The Portuguese universities have diversified their strategies to promote formal, informal and non formal entrepreneurial learning that can be encouraged in various strategies. The participation of key actors and stakeholders involved in awareness,mentoring and project implementation of the entrepreneurial learning process is crucial for collaborating work in a competitive world. Moreover, obtaining employment is increasingly dependent on not only the potentials of individuals, but also, and even more, the ability to build solid networks of partnerships in science and innovation and employment. Within the scope of the ongoing project "Entrepreneurial Learning, Cooperation and the Labour Market: Good Practice in Higher Education" this paper aims to highlight the importance of non formal and informal learning and to contribute to the reflection regarding added value of inter organizational cooperation and collaborative work

GEOTECNOLOGIAS APLICADAS NA AVALIAÇÃO DA ADEQUABILIDADE DA ÁREA DE ATERRO SANITÁRIO: UM ESTUDO NO MUNICÍPIO DE PRESIDENTE BERNARDES – SP

A seleção de áreas para aterros sanitários deve atender a diversos critérios estabelecidos em legislação e por órgãos ambientais para minimizar impactos ambientais. Este trabalho avalia a adequação da área do aterro de resíduo sólido no município de Presidente Bernardes – SP, no Pontal do Paranapanema. O método se consistiu da: revisão dos parâmetros para adequabilidade de locais de instalação de aterro; elaboração de cartas temáticas e da carta síntese para avaliação da área do aterro. Na produção das cartas, utilizou-se dados cartográficos disponibilizados, gratuitamente, usando software de Sistema de Informação Geográfica. Aplicou-se a inferência geográfica por lógica booleana na geração da carta síntese. Conclui-se que a área do aterro está inadequada por não atender a todos os parâmetros requeridos pela legislação brasileira. Recomenda-se o uso de outros métodos de inferência geográfica, como a média ponderada

Fluid flow profile in a packed bead column using residence time curves and radiotracer techniques

Filling columns are extremely important in the chemical industry and are used for purification, separation and treatment processes of gas or liquid mixtures. The objective of this work is to study the hydrodynamics of the fluid for a characterization of aqueous phase flow patterns in the filling column, associating with the methodology of the Curves of Residence Time Distribution (RTD) to analyze and associate theoretical models that put as conditions column operating. RTD can be obtained by using the pulse-stimulus response technique which is characterized by the instantaneous injection of a radiotracer into the system input. In this work, 68Ga was used as radiotracer. Five shielded and collimated NaI (Tl) 1x1" scintillator detectors were suitably positioned to record the movement of the radiotracer's path in the conveying line and filling column. Making possible the analysis of the RTD curve in the regions of interest. With the data generated by the NaI (Tl) detectors with the passage of the radiotracer in the transport line and inside the column, it was possible to evaluate the flow profile of the aqueous phase and to identify operational failures, such as internal conduit and the existence of a retention zone in the inside the column. Theoretical models were used for different flow flows: the piston flow and perfect mixing

Two genotypes of mycorrhizal Pinus pinaster respond differently to cadmium contamination

Fertilization is one of the main anthropogenic sources of Cd accumulation in agricultural soils and when toxic levels have been reached, food crop production is no longer viable. Adequate strategies for the forestation of agricultural metal contaminated sites are of vital importance. The aim of this work was to evaluate the response of two different genotypes of P. pinaster (A and B) to Cd contamination and to assess how inoculation with ectomycorrhizal fungi influenced each genotype. Seedlings were exposed to soil contaminated at different levels of Cd. At 30 mg Cd kg-1 non-inoculated genotype A accumulated more Cd in the shoots. At the lowest Cd concentration S. bovinus decreased Cd shoot concentration and increased aboveground development in both genotypes. At the highest Cd dosage inoculation with R. roseolus decreased Cd concentration in the roots of genotype B whereas the opposite occurred in genotype A. The results from this study suggest that the selection of an adequate combination between genotype and associated mycobionts may be an important biotechnological tool to enhance the efficiency of forestation and phytoremediation processes of degraded land using P. pinaster

DRIVER PREFERENCE CONCERNING IN-CAR ROUTE GUIDANCE AND NAVIGATION SYSTEM MAPS FOR DRIVERS WITH COLOR VISION DEFICIENCY

In-car Route Guidance and Navigation Systems (RGNS) are used to help drivers navigate. These maps have mainly been designed to accommodate drivers with normal color vision. However, the color perception of people with normal color vision differs from that of people with color vision deficiency. When navigating, understanding certain kinds of information presented by RGNS maps can be a more complex task for colorblind drivers and traffic safety may be impacted negatively. An important aspect related to the graphic design of RGNS maps is the use of a good combination of colors to improve map legibility. Cartographic representations with good legibility aid drivers in comprehending information and making appropriate decisions during driving tasks. This paper evaluates driver preference for RGNS maps designed for drivers with color vision deficiency. A total of 14 subjects participated in an experiment performed in a parked car. Maps were designed to accommodate red-blinds and green-blinds by using a color simulator and principles of perceptual grouping and figure-ground segregation. Based on the results, we conclude that the map grouping symbols representing car and direction arrows in blue segregated from the route in black was more acceptable to drivers compared to other combinations. It is recommended that RGNS should offer a specific graphic design to support drivers with color vision deficiency in navigating

Inoculation with ectomycorrhizal fungi affects Pinus pinaster performance under cadmium exposure

Afforestation of contaminated sites can represent a valuable approach to restore degraded ecosystems. Studies on the response of woody species to heavy metal contamination in soil are scarce compared to crop species. Cadmium is one of the most toxic heavy metals and its hazardous effects are well known. The aim of this work was to evaluate Pinus pinaster performance on Cd contaminated soil (15 and 30 mg Cd kg-1) and determine whether inoculation with two ectomycorrhizal fungi, Suillus bovinus and Rhizopogon roseolus influenced such response. Regarding non-inoculated seedlings, Cd exposure led to a lower shoot biomass and metal accumulation on the root system was proportional to its concentration in the soil. Inoculation with S. bovinus was the most favorable treatment for P. pinaster development by enhancing shoot development up to 1.3-fold in contaminated soil. Inoculation with R. roseolus increased Cd concentration in the shoots with no significant effect in any of the biometric traits studied. Metal accumulation on the shoots and roots of P. pinaster seedlings was significantly affected by the interaction between mycorrhizal inoculation and the Cd concentration to which the seedlings were exposed. Results from this study show that inoculation with selected ECM fungi can influence the performance of P. pinaster under Cd exposure and that this biotechnological tool could be of great value for plant establishment in contaminated sites

Análise da Acurácia Altimétrica do Modelo Digital de Superfície ALOS AW3D30 para o Mato Grosso do Sul

O Mato Grosso do Sul apresenta riquezas ambientais a se destacar. O Pantanal, como exemplo, é a maior área alagável do planeta e é considerado patrimônio natural da humanidade pela Unesco. Os MDS (Modelos Digitais de Superfície) são utilizados para diversas aplicações, no que tange a representação do terreno. Existem diversos MDS que são disponibilizados gratuitamente. Os dados do ALOS AW3D30 foram disponibilizados gratuitamente em maio de 2015, e são escassos os estudos visando sua validação. Nesse sentido, o objetivo do trabalho foi avaliar a acurácia altimétrica do MDS ALOS AW3D30, para o Estado do Mato Grosso do Sul. Utilizamos dados de 167 estações SAT-GPS do IBGE como pontos de referência altimétrica. Para fins comparativos, utilizou-se o SRTM (30 m) versão 3, pois consiste em um dos MDS mais conhecidos, o qual apresentou resultados mais acurados em estudo anterior. Para desenvolver a análise dos MDS, aplicou-se o Padrão de Exatidão Cartográfica dos Produtos Cartográficos Digitais – PEC-PCD. Verificou-se que o MDS ALOS AW3D30 apresenta RMSE (Root Mean Square Error) menor que o SRTM, indicando que para os dados avaliados apresenta maior acurácia. Para o estado do Mato Grosso do Sul, conclui-se que a acurácia altimétrica dos dados do ALOS AW3D30, assim como aqueles do SRTM, têm acurácia compatível com a escala 1:50.000, classe A, PEC-PCD

Conclui-se que a produção cartográfica contribui para a elaboração do inventário físico territorial da bacia e, consequente, planejamento ambiental da mesma

Distribuição dos casos de cardiopatias congênitas em um hospital do Oeste Paulista

O objetivo deste trabalho foi analisar a distribuição espaço-temporal dos pacientes com cardiopatias congênitas atendidos no Ambulatório de Cardiologia Pediátrica do Hospital de referência do Oeste Paulista. Realizamos um estudo retrospectivo com análise de dados de base eletrônica e prontuários dos pacientes diagnosticados com cardiopatiacongênita entre os períodos de julho de 2013 a julho de 2018. Foram selecionados 298 prontuários para análise das variáveis de CID-10, gênero, distribuição espacial e série temporal. Foi possível observar que os defeitos septais foram as cardiopatias mais prevalentes, não houve diferença entre os gêneros. Notou-se aumento do diagnóstico a partir de 2014, com implementação do teste do coraçãozinho e 51% dos casos eram da cidade de Presidente Prudente,com maior concentração de casos na região do parque industrial. Há uma relação na incidência das malformações cardíacas com o meio ambiente desfavorável. Os resultados encontrados podem guiar políticas de saúde pública, visando reduzir a exposição da população mais vulnerável, na busca da melhora nos índices de saúde.The aim of this research was to conduct a comprehensive spatial-temporal analysis of the population affected by congenital heart anomalies assisted at the Pediatric Cardiology Outpatient Department at the distinguished Western Paulista reference hospital. We conducted a retrospective study involving the analysis of electronic databaserecords and patient medical charts for individuals diagnosed with congenital heart disease during the period from July 2013 to July 2018. A total of 298 medical records were selected for the analysis of variables encompassing the ICD-10 codes, gender, spatial distribution, and temporal trends. It was possible to observe that septal defects were the most prevalent congenital heart abnormalities, and there was no gender-based difference. An increase in diagnoses was noted from 2014, coinciding with the implementation of the “heart test,” and 51% of the cases were from Presidente Prudente, with a higher concentration of cases in the industrial park area. There is an association between cardiac congenital malformations and an adverse environmental context. The findings can inform public health policies aimed at reducing the exposure of the most vulnerable population in pursuit of improvinghealth indicators
