Proposta para a estimativa da acurácia de redes geodésicas horizontais integrando análise de robustez e de covariância

The goal of this paper is to present a methodology for quality control of horizontal geodetic networks through robustness and covariance analysis. In the proposed methodology, the positional accuracy of each point is estimated by a possible bias in their position (based on robustness analysis), in addition to its own positional precision (uncertainty) (through covariance analysis), being a measure independently from the choice of the datum. Besides presenting the theoretical development of the method, its application is demonstrated in a numerical example. The results indicate that, in general, the greater the distance of an unknown point to the control(s) point(s) of the network, the greater is the propagation of random errors on this unknown point, and the smaller the number of redundant observations around a unknown point, the greater the influence of possible (undetected) non-random errors on this point.

Espondilomielopatia cervical caudal em cães: diagnóstico por imagem

The Caudal Cervical Spondylomyelopathy, also known as “Wobbler syndrome” is a neurological disorder that affects mainly breeds of large and giant size, especially Doberman pinsher and Great danes. Its aetiology is multifactorial and leads to a narrowing of the spinal canal by morphological and positional caudal cervical vertebrae (C5, C6 and C7), causing compression of the spinal cord and nerve roots. The clinical signs presented by the affected animals are progressive ataxia of hindlimbs and, later, the forelimbs, sometimes progressing to tetraparesis. Neck pain may be present. The diagnosis is made through the association of clinical signs and diagnostic imaging such as radiography, myelography, computed tomography and magnetic resonance imaging. According to the classification of the lesion obtained by imaging examinations, the conservative or surgical treatment is established and the prognosis is variable in accordance with the degree of affection of the spinal cord

The symbology of the sea in Lygia Bojunga Nunes's work: a reflection on utopian and dystopian framing

The ambivalent image of the sea is recurrent in Bojunga Nunes’s work. It receives a lot of symbolic meanings in her production, being sometimes a positive and sometimes a negative element. Thus, the sea is used in a utopic way, as a place for pleasure and leisure, and in a dystopic way, as scenery of a rite of passage, which includes the pain and suffering, part of the rite of passage that characterizes the bildungsromans. So, if in some texts the sea assumes a utopic character, being a place of snuggle, security, the ideal to reach, in others it is represented as dystopic, a place of distress, asphyxia and death. In this text we will study the hypothesis that, even in its dark symbolic meaning, in the author’s work the sea is an element of reflection and revelation. Thereby, it assumes metaphorically a sense of magnification of the reader’s expectative, being an element of emancipation. The objective of this text is to present a reflection on the sea’s symbolism on the mentioned texts and its importance for the reader’s formation.

Quantitative trait loci with sex-specific effects for internal organs weights and hematocrit value in a broiler-layer cross

Rapid growth in broilers is associated with susceptibility to metabolic disorders such as pulmonary hypertension syndrome (ascites) and sudden death. This study describes a genome search for QTL associated with relative weight of cardio respiratory and metabolically important organs (heart, lungs, liver and gizzard), and hematocrit value in a Brazilian broiler-layer cross. QTL with similar or different effects across sexes were investigated. At 42 days of age after fasted for 6 h, the F2 chickens were weighed and slaughtered. Weights and percentages of the weight relative to BW42 of gizzard, heart, lungs, liver and hematocrit were used in the QTL search. Parental, F1 and F2 individuals were genotyped with 128 genetic markers (127 microsatellites and 1 SNP) covering 22 linkage groups. QTL mapping analyses were carried out using mixed models. A total of 11 genome-wide significant QTL and five suggestive linkages were mapped. Thus, genome-wide significant QTL with similar effects across sexes were mapped to GGA2, 4 and 14 for heart weight, and to GGA2, 8 and 12 for gizzard %. Additionally, five genome-wide significant QTL with different effects across sexes were mapped to GGA 8, 19 and 26 for heart weight; GGA26 for heart % and GGA3 for hematocrit value. Five QTL were detected in chromosomal regions where QTL for similar traits were previously mapped in other F2 chicken populations. Seven novel genome-wide significant QTL are reported here, and 21 positional candidate genes in QTL regions were identified.

Registros posicionais de protrusão e lateralidade em resinaacrílica à partir de diferentes posições iniciais

The lateral movement presents a combination of lateral condylar and protrusive displacement on the non-working side. The objective os this study was to check the differences in the adjustment of the semiadjustable articulator starting from two different initial positions, centric relation an intercuspal position using positional records of rotusion and lateral movements in acrylic resin for the adjustment of condylar guidance as for ennett Angle. Twenty pacients dentate and assintomatic were recruited and their adjustment were performed in the semiadjustable articulator checking the differences among the studied groups, not finding statistically significant differences. Concludes that, in semiadjustable articulator adjustment, starting the montage in centric relation or intercuspal position, the results obtained for the condylar guidande and Bennett Angle aren´t statistically diferents, as well there is no difference in condylar guidance adjustment using lateral or protrusive records.
