Concentrations of Pb, Cd and Zn in sediments of an estuarine complex affected by ancient mining activities in Southeast Brazil

Abstract: An artificial canal, built in 1852, diverted 60% of the flow of the Ribeira de Iguape River (RIR) into the northern region of the Estuarine-Lagoon Complex of IguapeCananéia (ELCIC), Southeast Brazil. Since then the river has become the main contributor of fresh water and suspended matter into the system. Additionally, the RIR was contaminated by mining activities, especially of Pb, which disposed their wastes directly into this river from their beginning until its cease in 1996. Thus, unknown quantities of metals began to be continuously introduced into the ELCIC. This study evaluated lead, cadmium and zinc concentrations in the surficial sediment at 10 points sampled along the ELCIC, 15 years after the closure of the mining. Zinc concentrations were in accordance with legislation and similar across the ELCIC regions, ranging from 10.4 to 22.8 μg.g. Lead concentrations ranged from 19.3 to 67.9 μg.g, with higher concentrations in the northern ELCIC region, especially in areas near to the canal and the mouth of the RIR. These values were above the Level I limits established by the Brazilian Environmental Agency, suggesting the possibility of a sediment toxicity. Cadmium was only detected (up to 3.6 μg.g) in the northern region, exceeding Level I limits too. However, Pb and Cd values were not above the Level II limits. Results revealed areas of moderate lead and cadmium contamination in the northern ELCIC region, still indicating a strong contribution from the ancient mining activities and from other current anthropogenic activities such as agriculture or an incorrect disposal of sewage and residues. Therefore, a continuous assessment of metal concentrations in the sedimentary record is important to monitor the ELCIC environmental quality.

Relação entre intraempreendedorismo e inovação: um estudo em empresas participantes do APL de TI do sudoeste do Paraná

Abstract: This study aimed to verify the existence of relationship between Product Innovation Index (Inip) and intrapreneurial practices in the APL technology companies in the Southwest of Parana information Using quantitative methods, with application of two questionnaires to managers and employees responsible for R & D in 47 companies sent in survey format, with the final sample comprised of 16 companies The analysis was performed using descriptive statistics, followed by calculating the Inip and finally by the r Spearman correlation test The results revealed that in most companies the product innovation index presented himself down, also showed the perception of the factors that influence the intrapreneurship However, the correlation between the Inip and intrapreneurship factors did not indicate the existence of relations (significance level of r > 0005) Only when analyzed separately, intrapreneurship variable pointed moderate positive correlation

Characteristics of melanoma in the elderly.

Abstract: Objective This study evaluates melanoma characteristics in the elderly Methods A retrospective descriptive analytical study was carried out by reviewing the medical records of patients aged 60 years or older, diagnosed with primary cutaneous melanoma, and treated at Hospital Erasto Gaertner, Curitiba, Parana, from 2013 to 2017 Results We studied 139 patients aged 60-98 years (average, 703 years) and found melanoma to be more common in women (525%) than in men Lesions mainly affected the limbs (323%) and head (244%), showed signs of ulceration (338%), and could be classified into the nodular histological (29%), extensive superficial (27%), and acral (12%) types The average Breslow index was 12 mm Metastasis occurred in 33% of the patients and mainly affected lymph nodes (36%) and the central nervous system (CNS, 20%) The first procedure conducted in 79% of the cases was surgical resection Sentinel node mapping was carried out in 417% of the cases, and surgical treatment alone was indicated in 70% of the patients The disease recurred in 345% of the patients, and 179% succumbed to the disease These results indicate that the elderly have poorer prognosis when cancer treatment is delayed Conclusion Melanoma of the limbs and head, intermediate Breslow index, metastatic lymph node and CNS metastases, and relapse result in fatal outcomes Direct strategies, such as prevention and early detection, as well as uniform and adequate treatment, are needed to improve disease management in the elderly

Ocorrência de Classes Gramaticais na Fala Espontânea de Crianças de 18 a 41 Meses com Pares

Abstract: Este estudo teve como objetivo investigar a ocorrencia de diferentes categorias gramaticais em 21 criancas (18 a 41 meses), interagindo espontaneamente com pares; e comparar esses dados com estudos que empregam a observacao da interacao adulto/crianca em contexto de fala elicitada Cada participante foi filmado durante 15 minutos, por cinco vezes (em intervalos de um mes) interagindo com colegas de classe Os registros foram distribuidos em quatro grupos etarios As categorias gramaticais mais frequentes em todos os grupos foram verbos e substantivos A frequencia de tipos de verbos e substantivos foi equivalente entre os grupos mais jovens, mas verbos foram mais frequentes nos grupos mais velhos Discute-se o papel do contexto de observacao e do metodo de coleta de dados
