Uma abordagem ergonômica para análise da qualidade do pescado, desde sua captura ao seu desembarque na praia, resultante da atividade dos jangadeiros de Ponta Negra - Natal/RN

The artisan fishing activity, which involves historical - cultural, environmental, social, political, economi c, among other factors, presents, nowadays, as an important source of income, creating jobs and food, contributing to the permanence of man in their own birthplace. However, the fish, considered one of the most perishable foods, requires a proper handling and conservation, from capture to its availability in the market, in order to slow the deterioration process. Thereby, this dissertation aims to study the effect of the manipulation practices on fish quality, from capture to its landing on the beach, resul ting from fisherman’s activity from Ponta Negra - Natal/RN. It also presents the purpose of analyzing the quality of the fish and propose recommendations for their proper handling and possible solutions to add value to the product, through the improvement of the quality and good handling practices. For this purpose, the methodology used was based on ergonomic analysis of their work through observational techniques and interactional with the focus group, the jangadeiros, to understand their activity and eval uated the freshness and quality of the fish by sensory analysis, and microbiological parameters and physicochemical from existing legislation Ordinance No. 185 of May 13, 1997 and RIISPOA - amended on December 1, 2007 and RDC No. 12, dated January 2, 2001. According to the results obtained in laboratory tests, it can be established, the acceptable quality of fish as the existing rules and regulations parameters , not getting significant deterioration caused by poor handling and improper storage of fish.

Síntese e caracterização de materiais mesoporosos para a captura de CO2: influência do óxido de níquel

Several materials are currently under study for the CO2 capture process, like the metal oxides and mixed metal oxides, zeolites, carbonaceous materials, metal-organic frameworks (MOF's) organosilica and modified silica surfaces. In this work, evaluated the adsorption capacity of CO2 in mesoporous materials of different structures, such as MCM-48 and SBA- 15 without impregnating and impregnated with nickel in the proportions 5 %, 10 % and 20 % (m/m), known as 5Ni-MCM-48, 10Ni-MCM-48, 20Ni-MCM-48 and 5Ni-SBA-15, 10NiSBA-15, 20Ni-SBA-15. The materials were characterized by means of X-ray diffraction (XRD), thermal analysis (TG and DTG), Fourier transform infrared spectroscopy (FT-IR), N2 adsorption and desorption (BET) and scanning electron microscopy (SEM) with EDS. The adsorption process was performed varying the pressure of 100 - 4000 kPa and keeping the temperature constant and equal to 298 K. At a pressure of 100 kPa, higher concentrations of adsorption occurred for the materials 5Ni-MCM-48 (0.795 mmol g-1 ) and SBA-15 (0.914 mmol g-1 ) is not impregnated, and at a pressure of 4000 kPa for MCM-48 materials (14.89 mmol g-1) and SBA-15 (9.97 mmol g-1) not impregnated. The results showed that the adsorption capacity varies positively with the specific area, however, has a direct dependency on the type and geometry of the porous structure of channels. The data were fitted using the Langmuir and Freundlich models and were evaluated thermodynamic parameters Gibbs free energy and entropy of the adsorption system

Desenvolvimento de um sistema de captura de baixo custo destinado a determinação da cinemática humana

The motion capture is a main tool for quantitative motion analyses. Since the XIX century, several motion caption systems have been developed for biomechanics study, animations, games and movies. The biomechanics and kinesiology involves and depends on knowledge from distinct fields, the engineering and health sciences. A precise human motion analysis requires knowledge from both fields. It is necessary then the use of didactics tools and methods for research and teaching for learning aid. The devices for analysis and motion capture currently that are found on the market and on educational institutes presents difficulties for didactical practice, which are the difficulty of transportation, high cost and limited freedom for the user towards the data acquisition. Therefore, the motion analysis is qualitatively performed or is quantitatively performed in highly complex laboratories. Based is these problems, this work presents the development of a motion capture system for didactic use hence a cheap, light, portable and easily used device with a free software. This design includes the selection of the device, the software development for that and tests. The developed system uses the device Kinect, from Microsoft, for its low cost, low weight, portability and easy use, and delivery tree-dimensional data with only one peripheral device. The proposed programs use the hardware to make motion captures, store them, reproduce them, process the motion data and graphically presents the data.

Incidental Capture of Loggerhead Turtles (Caretta caretta) on Boa Vista (Cape Verde Islands)

[EN] The sea is one of the major natural resources of the Cape Verde Islands, a small archipelago located 500 kilometers off the coast of Senegal (West Africa). This country consists of ten main islands and several islets, and possesses an Exclusive Economical Zone (EEZ) of about 734 square kilometers and a coastal perimeter of nearly 2000 kilometers. The marine shelf, whose limit is the 200 m isobath, is particularly extensive on the island of Boa Vista (Figure 1). lt is likely that most of the loggerhead turtles (Caretta caretta) that breed in this archipelago are concentrated on this island (López-Jurado et al., 1999).

Incidental cancer in patients surgically treated for benign thyroid disease. Our experience at a single institution

Increased incidence of incidental cancer in patients operated for benign thyroid disease has been reported. We report our experience about incidental thyroid cancer (ITC) in order to better characterize this nosologic entity. Between 2001 and 2009 a total of 568 patients underwent surgery for benign thyroid disease. Patients with preoperative cytology undetermined or positive for malignancy were excluded. The most frequent indication for surgery was multinodular or diffuse nontoxic goiter. We performed total thyroidectomy in 499 cases and emithyroidectomy in 69 cases. Final histology revealed ITC in 53 patients (9.3%): 44 had papillary carcinoma (20 classic variant and 24 follicular variant), 4 follicular carcinoma, 4 medullary carcinoma and 1 primitive thyroid paraganglioma. The preoperative diagnosis was multinodular or diffuse goiter in 45 cases of ITC and uninodular goiter in 8 cases. We performed total thyroidectomy in 46 case, emithyroidectomy in 4 patients with past history of lobectomy, emithyroidectomy in 3 patients with following radicalization and central neck dissection. In 14 patients the tumor was multifocal and in 12 of these patients the tumor foci were bilateral. The lesion was a microcarcinoma in 34 cases. Mean diameter of the ITC was 1.14 cm. We retrospectively reconsidered the results of preoperative ultrasound examinations in relation to the exact position of the tumor in the specimens and we found a statistically significant association between echogenicity and papillary histotype. Twenty-six patients were followed up at our Hospital. The mean follow-up period was 38.2 months. A relapse was observed in 3/26 patients. Incidental thyroid cancer in patients operated for benign disease has its own surgical and oncological relevance. A correct preoperative assessment, with a careful selection of nodules for fine-needle aspiration cytology on the basis of ultrasound pattern, could better address the choice of surgical procedure. The non irrelevant incidence of incidental thyroid cancer, the eventuality of multifocality and bilaterality and the possible occurrence of relapse, support that total thyroidectomy without residuum is a valuable option for treating benign thyroid conditions such as multinodular goitre. When an incidental cancer is diagnosed after emithyroidectomy, a radicalization with central neck dissection could be considered. We suggest that natural history of papillary microtumors and the correct surgical approach for these lesions could be better defined with a more extensive use of “Porto proposal” criteria.

Lagoa mirim: caracterização da pesca artesanal e composição da captura

Os ambientes aquáticos continentais da metade sul do RS são caracterizados por uma ampla planície costeira, onde destaca-se a Lagoa Mirim, com uma área total binacional (Brasil e Uruguai) de 3.750 Km². Nesta região, a pesca é uma importante atividade sócio-econômica, porém, a economia da região baseia-se no cultivo do arroz e na criação de gado. A proposta deste trabalho foi realizar um diagnóstico preliminar desta atividade na L. Mirim. A metodologia foi baseada na aplicação de formulários aos pescadores artesanais (perfil sócio-econômico e características da pesca) e na identificação das espécies que compunham a captura proveniente do desembarque pesqueiro no entorno da L. Mirim (Jaguarão, Santa Isabel e Santa Vitória do PalmarPorto e Curral Alto). Os dados de captura total de pescado foram provenientes de fontes independentes e complementares. O estudo sugere um perfil do pescador artesanal composto por 71% de indivíduos de sexo masculino, entre 20 e 65 anos de idade que costumam ficar de uma semana a quinze dias embarcados. A maioria (71%) dos pescadores artesanais entrevistados possui somente ensino fundamental e seus familiares geralmente estão envolvidos na atividade pesqueira. Foram identificados 28 locais de pesca e as principais espécies capturadas pela pesca artesanal foram: traíra Hoplias malabaricus, jundiá Rhandia aff. quelen, pintado Pimelodus maculatus, peixerei Odontesthes spp, viola-cascuda Loricariichthys anus e tambico Oligosarcus spp. A traíra foi a espécie mais representativa em peso (> 40%). Estas espécies apresentaram flutuações na composição das capturas ao longo do ano; os menores valores foram registrados entre julho e setembro (meses frios), exceto para o peixe-rei. A análise dos dados também aponta uma variação interanual dos valores totais de pescado e alguns fatores que podem estar associados à diminuição da captura são os prolongados períodos de seca na região, o uso da água na orizicultura e a falta de fiscalização da atividade pesqueira. Estudos baseados em estimativas de pescarias e conhecimento sobre a biologia das espécies capturadas podem fornecer subsídios para o correto manejo dos recursos pesqueiros, para tanto, são necessárias pesquisas que investiguem aspectos do uso sustentado das espécies de importância econômica na região e os possíveis efeitos da atividade pesqueira sobre a estrutura e a biodiversidade do ecossistema. Assim, para garantir a sustentabilidade da Lagoa Mirim, faz-se necessário envolver os pescadores artesanais e suas estratégias de pesca, em função de seus conhecimentos ecológicos, nas pesquisas que integram a elaboração das políticas públicas.

Renal angiomyolipoma with renal vein thrombosis: an incidental finding

A 66-year-old female with history of endometrioid endometrial carcinoma was admitted to our institution with abdominal and pelvic pain. A CT scan revealed a mass within the right upper kidney with a tumour thrombus that extended through the right renal vein up to the point of confluence with the inferior vena cava (IVC). The imaging features of the mass strongly suggested a diagnosis of renal angiomyolipoma (AML) with renal vein thrombosis. The patient was proposed an open radical right nephrectomy with right renal thrombectomy for histopathological confirmation of the diagnosis of AML with extension to the right renal vein and preventing complications such as potentially fatal pulmonary thromboembolism. The implantation of a temporary IVC filter before surgery was recommended.

Learning English is Fun! Incidental vocabulary acquisition of music and traditional class ninth graders via listening to pop songs

Finnish youth are constantly exposed to music and lyrics in English in their free time. It is likely that this has a positive effect on vocabulary learning. Learning vocabulary while simultaneously accompanied with melodies is likely to result in better learning outcomes. The present thesis covers a study on the vocabulary learning of traditional and music class ninth graders in a south-western upper comprehensive school in Finland, mainly concentrating on vocabulary learning as a by-product of listening to pop music and learning vocabulary through semantic priming. The theoretical background presents viable linguistic arguments and theories, which provide clarity for why it would be possible to learn English vocabulary via listening to pop songs. There is conflicting evidence on the benefits of music on vocabulary learning, and this thesis sets out to shed light on the situation. Additionally, incorporating pop music in English classes could assist in decreasing the gap between real world English and school English. The thesis is a mixed method research study consisting of both quantitative and qualitative research materials. The methodology comprises vocabulary tests both before and after pop music samples and a background questionnaire filled by students. According to the results, all students reported liking listening to music and they clearly listened to English pop music the most. A statistically significant difference was found when analysing the results of the differences in pre- and post-vocabulary tests. However, the traditional class appeared to listen to mainstream pop music more than the students in the music class, and thus it seems likely that the traditional class benefited more from vocabulary learning occurring via listening to pop songs. In conclusion, it can be established that it is possible to learn English vocabulary via listening to pop songs and that students wish their English lectures would involve more music-related vocabulary exercises in the future. Thus, when it comes to school learning, pop songs should be utilised in vocabulary learning, which could also in turn result in more diverse learning and the students could, more easily than before, relate to the themes and topics of the lectures. Furthermore, with the help of pop songs it would be possible to decrease the gap between school English and real-world English.

Eficiência do atrativo a base de fermento biológico com diferentes tempos de fermentação na captura de Drosophila suzukii.

Drosophila suzukii é uma espécie nativa da Ásia com elevada capacidade de ocasionar danos em frutos sadios de uma diversidade de espécies vegetais, especialmente nos pequenos frutos. A falta de ferramentas adequadas para o monitoramento é fator limitante no desenvolvimento de métodos de manejo e controle da praga. A utilização de um atrativo a base de fermento biológico, açúcar e água tem se mostrado eficiente e seletivo na captura de D. suzukii em áreas de pequenos frutos. Porém, há necessidade de informações mais precisas sobre o tempo necessário para fermentação do atrativo antes do seu uso no campo. Assim, este estudo teve como objetivo avaliar o tempo de fermentação necessário para uso do atrativo F1 (fermento, açúcar e água) no monitoramento de D. suzukii em pomar de pequenos frutos.
