Análise cinemática e cinética do salto vertical de crianças com transtorno do desenvolvimento da coordenação (TDC)

Due to motor difficulties, children with developmental coordination disorder (DCD) doesn't feel motivated to do physical activities, sometimes resulting in a decline of their physical fitness, but it isn't really known for sure the reasons that induct children with DCD to low performances in physical fitness tests, because a lot of tasks that are part of the battery of tests of physical performance are complex in the coordination and/or motor control point of view, like the vertical jump for example. Therefore, the objective of this study was to investigate the factors that induct children with DCD to low performances in physical fitness tests, especially in the vertical jump task. For that, cinematic (duration of the eccentrical phase, duration of the concentrical phase, shift of the mass center and velocity of the mass center), kinetic (potency peak and force peak) and vertical jump performance analysis in two conditions (with the use of arms and without it) were realized in a force platform. The results indicated that children with DCD show a lower performance compared to their peers with typical development (TD), due to a lower potency production

Determinação das coordenadas dos vértices limítrofes de imóveis rurais utilizando-se do posicionamento GPS

Aiming to evaluate the methodologies of surveys related with the specifications of Geo-referencing Rural Parcels in Brazil, established by INCRA (National Institute of Colonization and Agrarian Reform), in attendance to the Law 10.267/01, and considering aspects of precision and accuracy, a test area was set up in the Assentamento Florestan Fernandes, in the county of Presidente Bernardes, SP. This area was subdivided in three sub-areas in order to simulate the existence of three contiguous rural parcels. The first stage of work consisted in the implantation and determination of the control points coordinates in their respective areas. These control points were determined by the process of direct transport, using dual frequency (L1/L2) GPS receivers and through the process of traverse with baselines of up to 20 km, using single frequency receivers (L1). The coordinates of the points of the perimeter of the three sub-areas were determined using single frequency GPS receivers, from two survey methods, both using static relative positioning. The first one, so called traverse, each point that delimits the property was occupied successively, starting from the control point and closing at another. In other, denominated double irradiation, each point of the property was irradiated from two control points. These procedures were accomplished with the intention to define and to implement a mistake control strategy, to realize redundancy measurements and to use an adjustment method correctly, to obtain trustworthily values in the patterns demanded in each kind of survey. With the data collected and processed some analyses could be accomplished from the discrepancies between the coordinates obtained by different methodologies. The results show that this test area may be used to validate other methodologies and equipments. The results were satisfactory and attended the specifications of Geo-referencing Rural Parcel.

Ankle joint pressure changes in a pes cavovarus model after lateralizing calcaneal osteotomies

Tendon transfers and calcaneal osteotomies are commonly used to treat symptoms related to medial ankle arthrosis in fixed pes cavovarus. However, the relative effect of these osteotomies in terms of lateralizing the ground contact point of the hindfoot and redistributing ankle joint contact stresses are unknown.

Evaluating the relationship between moisture induced expansion and horizontal stress orientation in samples from the nonesuch formation

High horizontal stresses can cause numerous ground control problems in mines and other underground structures ultimately impacting worker safety, productivity and the economics of an underground operation. Mine layout and design can be optimized when the presence and orientation of these stresses are recognized and their impact minimized. A simple technique for correlating the principal horizontal stress direction in a sedimentary rock mass with the preferential orientation of moisture induced expansion in a sample of the same rock was introduced in the 1970s and has since gone un-reported and unused. This procedure was reexamined at a locality near the original test site at White Pine, Michigan in order to validate the original research and to consider its usefulness in mining and civil engineering applications in high horizontal stress conditions. This procedure may also be useful as an economical means for characterizing regional stress fields.

Tracking of industrial objects by using CAD models

In this paper we present a model-based approach for real-time camera pose estimation in industrial scenarios. The line model which is used for tracking is generated by rendering a polygonal model and extracting contours out of the rendered scene. By un-projecting a point on the contour with the depth value stored in the z-buffer, the 3D coordinates of the contour can be calculated. For establishing 2D/3D correspondences the 3D control points on the contour are projected into the image and a perpendicular search for gradient maxima for every point on the contour is performed. Multiple hypotheses of 2D image points corresponding to a 3D control point make the pose estimation robust against ambiguous edges in the image.

Occurrence and Genetic Characteristics of Third-Generation Cephalosporin-Resistant Escherichia coli in Swiss Retail Meat

Prevalence and genetic relatedness were determined for third-generation cephalosporin-resistant Escherichia coli (3GC-R-Ec) detected in Swiss beef, veal, pork, and poultry retail meat. Samples from meat-packing plants (MPPs) processing 70% of the slaughtered animals in Switzerland were purchased at different intervals between April and June 2013 and analyzed. Sixty-nine 3GC-R-Ec isolates were obtained and characterized by microarray, PCR/DNA sequencing, Multi Locus Sequence Typing (MLST), and plasmid replicon typing. Plasmids of selected strains were transformed by electroporation into E. coli TOP10 cells and analyzed by plasmid MLST. The prevalence of 3GC-R-Ec was 73.3% in chicken and 2% in beef meat. No 3GC-R-Ec were found in pork and veal. Overall, the blaCTX-M-1 (79.4%), blaCMY-2 (17.6%), blaCMY-4 (1.5%), and blaSHV-12 (1.5%) β-lactamase genes were detected, as well as other genes conferring resistance to chloramphenicol (cmlA1-like), sulfonamides (sul), tetracycline (tet), and trimethoprim (dfrA). The 3GC-R-Ec from chicken meat often harbored virulence genes associated with avian pathogens. Plasmid incompatibility (Inc) groups IncI1, IncFIB, IncFII, and IncB/O were the most frequent. A high rate of clonality (e.g., ST1304, ST38, and ST93) among isolates from the same MPPs suggests that strains persist at the plant and spread to meat at the carcass-processing stage. Additionally, the presence of the blaCTX-M-1 gene on an IncI1 plasmid sequence type 3 (IncI1/pST3) in genetically diverse strains indicates interstrain spread of an epidemic plasmid. The blaCMY-2 and blaCMY-4 genes were located on IncB/O plasmids. This study represents the first comprehensive assessment of 3GC-R-Ec in meat in Switzerland. It demonstrates the need for monitoring contaminants and for the adaptation of the Hazard Analysis and Critical Control Point concept to avoid the spread of multidrug-resistant bacteria through the food chain.

Review of Clément Vidal, "The Beginning and the End. The Meaning of Life in a Cosmological Perspective"

No more ground control. Dissertations ideally always have been ambitious, and this one can’t claim to be too humble in these regards. Together the pieces of this work form a world view that the author confesses to finding ‘magnificent’. The story he tells is one in which intelligence and complexity are keys to unlock the universe’s mysteries. Vidal tackles questions like ‘What is philosophy?’, ‘Where does it all come from?’, Where are we going?’, ‘Are we alone in the universe?’ and even ‘What is good and what is evil?’. Questions which philosophers for ages have tried to answer.

Validated sample ages from 823 EPD sites

The number of well-dated pollen diagrams in Europe has increased considerably over the last 30 years and many of them have been submitted to the European Pollen Database (EPD). This allows for the construction of increasingly precise maps of Holocene vegetation change across the continent. Chronological information in the EPD has been expressed in uncalibrated radiocarbon years, and most chronologies to date are based on this time scale. Here we present new chronologies for most of the datasets stored in the EPD based on calibrated radiocarbon years. Age information associated with pollen diagrams is often derived from the pollen stratigraphy itself or from other sedimentological information. We reviewed these chronological tie points and assigned uncertainties to them. The steps taken to generate the new chronologies are described and the rationale for a new classification system for age uncertainties is introduced. The resulting chronologies are fit for most continental-scale questions. They may not provide the best age model for particular sites, but may be viewed as general purpose chronologies. Taxonomic particularities of the data stored in the EPD are explained. An example is given of how the database can be queried to select samples with appropriate age control as well as the suitable taxonomic level to answer a specific research question.

Geological map of HANSSONHORNA, Heimefrontfjella, Antarctica (Scale 1:25,000)

Topographic data of this geological map were obtained through stereoscopic aerial photo interpretation. The photogrammetric photo flights were undertaken in 1986 by the Institut für Angewandte Geodäsie, Frankfurt. Horizontal ground control points required for aerial photo interpretation were determined by means of Doppler satellite observation during the 2nd German Neuschwabenland Expedition 1985/86. Vertical ground control points were taken from unpublished map drafts at 1:100 000 scale by Norsk Polarinstitutt, Oslo. The elevation above mean sea level was transferred to Heimefrontfjella barometrically. For this reason assertions concerning the absolute elevation (referred to sea level) are uncertain. Contours and spot heights presented on the map were obtained from the photogrammetric evaluation of the photography taken in 1986; relative elevation data (hight differences) are accurate to approximately ±10 m.
