Removal of clay by stingless bees: load size and moisture selection

Some organisms disperse energy, associated with the transportation of resource, which is not necessarily food. Stingless bees of Central Amazonia (Melipona flavolineata and M. lateralis) collect clay in banks along streams for nest building. The moisture of the clay varies along the bank, and bees collect clay from specific location, indicating that there is some sort of preference regarding their selection. This study aims at identifying: if larger bees carry more clay; if there is a preference for moisture of substrates; and if bees are less efficient accumulating and transporting clay when it is wet. In order to do so, I measured the size of the bees and of the pellets of clay found in the corbicula. I set up a field experiment to test substrate preferences. The amount of clay transported, increased exponentially in accordance to the size of the bee, and the preferred substrate was the driest clay. The amount and the efficiency of removal of clay were not affected by the moisture of the substrate. Despite the wet clay being denser, it does not reduce the efficiency of exploitation of the resource, but suggests that bees spend more energy to carry the same quantity of wet clay, which may be the underlying mechanism explaining their preference for removing drier clay.

Image segmentation through combined methods: watershed transform, unsupervised distance learning and normalized cut

Research on image processing has shown that combining segmentation methods may lead to a solid approach to extract semantic information from different sort of images. Within this context, the Normalized Cut (NCut) is usually used as a final partitioning tool for graphs modeled in some chosen method. This work explores the Watershed Transform as a modeling tool, using different criteria of the hierarchical Watershed to convert an image into an adjacency graph. The Watershed is combined with an unsupervised distance learning step that redistributes the graph weights and redefines the Similarity matrix, before the final segmentation step using NCut. Adopting the Berkeley Segmentation Data Set and Benchmark as a background, our goal is to compare the results obtained for this method with previous work to validate its performance.

Trabalho e Educação: (des) emprego na Bahia

The article argues about the problematic of the technological modernization of the productive system, from years 80 and intensified in the 90, and its effect on the behavior of the labor market based in the state of the Bahia. From the few Demographic data of Census 2000 by the IBGE an analysis of the Bahia state force of work was affected mainly on the variable as employment, wage profit, race, sort and years of studies. The data show, among others questions, a labor market with a low-level of education and low wages with strong exclusion in relation to the race and sort.

Antropometria da mão humana: influência do gênero no design ergonômico de instrumentos manuais

The wrong sizing of handle instruments can generate ergonomic problems. To know the anthropometry of the hands is indispensable for a correct sizing, especially how much the gender influences in this aspect. The objective of this study was quantitatively to evaluate the influence of the sort in the anthropometry of the hand human being. The results indicate that the differences are significant and that this factor must be considered in design of manual instruments.

Introdução a ontologias e suas aplicações

Different vocabularies and contexts are barriers to the communication between people or software systems. It is necessary a common understanding in the domain that is talked about, so it can be obtained a correct interpretation of the information. An ontology formally models the structure of a domain and turn explicit the shared understanding in the form of concepts and relations that emerge from its observation. Constitutes a sort of framework used in the mapping to the meaning of the information that is talked about. The formal accuracy in which they are defined, by means of axioms, allow machine processing, implicating in systems interoperability. Structured this way, the knowledge is easily transferred between people or systems from different contexts. Ontologies present several applications nowadays. They are considered the infra-structure to the Semantic Web, which is composed by Web resources with embedded meaning. Thereby, the automatic execution of complex tasks is allowed, with the benefit from the effective communication between Web software agents. Among other applications, they also have been used to structure the knowledge generated from several areas, like Biology and Software Engineering.

On an energy exchange process and appearance of chaos in a non-ideal portal frame dynamical system

In this paper, we consider non-ideal excitation devices such as DC motors with restrictenergy output capacity. When such motors are attached to structures which needexcitation power levels similar to the source power capacity, jump phenomena and theincrease in power required near resonance characterize the Sommerfeld Effect, actingas a sort of an energy sink. One of the problems often faced by designers of suchstructures is how to drive the system through resonance and avoid this energy sink.Our basic structural model is a simple portal frame driven by a num-ideal powersource-(NIPF). We also investigate the absorption of resonant vibrations (nonlinearand chaotic) by means of a nonlinear sub-structure known as a Nonlinear Energy Sink(NES). An energy exchange process between the NIPF and NES in the passagethrough resonance is investigated, as well the suppression of chaos.

Avaliação do consumo alimentar e percepção da imagem corporal de culturistas

In bodybuilding, sport that emerged in Brazil in the 70s, competitors are judged by physical appearance, size and muscle definition. The present study aimed to assess dietary intake, supplement use, and it also investigated body image perceptions of bodybuilders. Practitioners of three different gyms in the state of São Paulo participated in the study. They filled the anamnesis form containing data on food consumption and intake of supplements and also answered a questionnaire on the perception of body image (Satisfaction Scale with Body Appearance). The study showed a considerable food inadequacy with an average of carbohydrate intake of 41.84% ± 10.88%, of lipid, an average of 18.96% ± 6.40% and of protein 39.20% ± 10.41%. In pre-competition, the average of daily carbohydrate intake is reduced to 22.69% ± 12.34%, the lipid increases to 25.68% ± 14.0% and the protein increases to 51.63% ± 10.28%. It was observed that all individuals take some sort of supplement. Considering the perception of body image 60% of the appraised are fully satisfied with the muscular appearance and 40% has greater risk of developing vigorexia. As the bodybuilder has rigid dietary control, it is important nutritional monitoring. So it is necessary a better identification and guidance of risk groups for the development of body image disturbances through specialized professionals such as dieticians, psychologists and coaches for success training, aiming at physical and mental well being of the athletes.

Reproducibility of heart rate and rating of perceived exertion values obtained from different incremental treadmill tests

Objective The present study aimed to examine the reproducibility of heart rate (HR) and rating of perceived exertion (RPE) values obtained during different incremental treadmill tests. Equipment and methods Twenty male, recreational, endurance-trained runners (10-km running pace: 10–15 km·h−1) performed, in a counterbalanced order, three continuous incremental exercise tests with different speed increments (0.5 km·h−1, 1 km·h−1 and 2 km·h−1). Thereafter, each participant performed the three tests again, maintaining the same order as before. The reproducibility of the HR and RPE values were analyzed for all protocols during submaximal intensities (8, 10, 12, and 14 km·h−1). In addition, it was examined the reproducibility of maximal HR (HRmax) and peak RPE (RPEpeak). Results The variability of both the HR and RPE values showed a tendency to decrease over the stages during the incremental test and was not or slightly influenced by the incremental test design. The HR at 14 km·h−1 and HRmax presented the highest reproducibility (CV < 2%). In contrast, the submaximal RPE values showed higher variability indices (i.e., CV > 5.0%). In conclusion, the HR values were highly reproducible during the stages of the incremental test, in contrast to the RPE values that presented limited reproducibility.

Formação continuada de professores como um projeto coletivo e de identidade profissional

This research is part of the field of teacher training, especially developed the topic of continuing education. There is, according to the literature, the importance of this training for teachers as a sort of continuum, trajectory in which the teacher will (re) building their knowledge throughout their lives, in order to provide knowledge and values that add to your practice teaching. However, often the training activities are designed for knowledge transmitter model forming agent for the teacher, disregarding the different contexts of school communities, this strategy which hardly reaches the real needs of teachers in their daily lives. It is evident, too, the need to provide, in training moments, spaces to engage in dialogue and reflect on the teachers profession today, (re) building thus their teacher identity. In this context, the objective of this research is to examine whether the continued formation is configured as a collective construction and as a space for reflection on what it means to be a teacher. The research is characterized by a qualitative approach, and to collect data, we used the semi-structured interview technique. Participants were five teachers in the areas of Physical Education, History, English, Portuguese and Mathematics, a state school Treble city education (SP). The results show the importance of continuing education for teachers, which provides reflections, discussions, acquisition of knowledge and skills that contribute to its performance, motivating and developing strategies to enable them to face the challenges of everyday life and reflect collectively on what it means to be a teacher. It was concluded that continuing education for this group of teachers is configured as a space for collective construction, which together with other teachers rethink, reflect and continuously reconstruct their practices and objectives, and enables reflection on the teaching profession constantly. It will be essential, therefore...
