Facial growth evaluation of complete unilateral cleft lip and palate operated patients: a cleft reference center in Paraíba, Brazil, using the GOSLON yardstick

Objectives: To evaluate the surgical outcomes of patients with complete unilateral cleft lip and palate (CUCLP) operated on by a single surgeon of the cleft reference center of the Lauro Wanderley University Hospital at the Federal University of Paraiba. Methods: Forty-four individuals' dental casts diagnosed with CUCLP, born between 1995 and 2002, mean age of 11 years, were evaluated by three calibrated orthodontic specialists and scored by the Great Ormond Street, London and Oslo (GOSLON) yardstick on two occasions. The scores were compared with those observed in other centers around the world. The Kappa test was applied to evaluate the intra- and inter-examiner agreement. Descriptive statistics was applied for the GOSLON yardsticks core. Results: The mean GOSLON score was 2.75. For the GOSLON yardstick, 43.2 % of the sample presented scores 1 and 2, 31.8 % had score 3, and 25 % were with scores 4 and 5. There was very good intra- and inter-examiner Kappa agreement in the application of the GOSLON yardstick. Conclusions: The data suggest favorable outcomes, with 75 % of cases with no need of orthognathic surgery. The Kappa values confirmed the high reproducibility of the GOSLON yardstick. © 2013 Springer-Verlag Berlin Heidelberg.

Bilevel approach for optimal location and contract pricing of distributed generation in radial distribution systems using mixed-integer linear programming

In this study, a novel approach for the optimal location and contract pricing of distributed generation (DG) is presented. Such an approach is designed for a market environment in which the distribution company (DisCo) can buy energy either from the wholesale energy market or from the DG units within its network. The location and contract pricing of DG is determined by the interaction between the DisCo and the owner of the distributed generators. The DisCo intends to minimise the payments incurred in meeting the expected demand, whereas the owner of the DG intends to maximise the profits obtained from the energy sold to the DisCo. This two-agent relationship is modelled in a bilevel scheme. The upper-level optimisation is for determining the allocation and contract prices of the DG units, whereas the lower-level optimisation is for modelling the reaction of the DisCo. The bilevel programming problem is turned into an equivalent single-level mixed-integer linear optimisation problem using duality properties, which is then solved using commercially available software. Results show the robustness and efficiency of the proposed model compared with other existing models. As regards to contract pricing, the proposed approach allowed to find better solutions than those reported in previous works. © The Institution of Engineering and Technology 2013.

Decoupled reference generator for shunt active filters using the conservative power theory

Based on the framework of the Conservative Power Theory (CPT), this paper proposes some compensation strategies for shunt current compensators. CPT current decompositions result in several current-related terms associated with specific load characteristics, such as power consumption, energy storage, unbalances and load nonlinearities. These current components are decoupled (orthogonal) from each other and are used here to define different compensation strategies, which can be selective in minimizing particular effects of disturbing loads. Compensation strategies for single- and three-phase four-wire circuits are also considered. Simulated and experimental results are described to validate the possibilities and performance of the proposed strategies. © 2013 Brazilian Society for Automatics - SBA.

Validation of a reference control for an SYBR-Green fluorescence assay-based real-time PCR for detection of bovine herpesvirus 5 in experimentally exposed bovine embryos

The objective of this study was to optimize an internal control to improve SYBR-Green-based qPCR to amplify/detect the BoHV-5 US9 gene in bovine embryos produced invitro and experimentally exposed to the virus. We designed an SYBR-Green-based binding assay that is quick to perform, reliable, easily optimized and compares well with the published assay. Herein we demonstrated its general applicability to detect BoHV-5 US9 gene in bovine embryos produced invitro experimentally exposed to BoHV-5. In order to validate the assay, three different reference genes were tested; and the histone 2a gene was shown to be the most adequate for normalizing the qPCR reaction, by considering melting and standard curves ( p<0.05). On the other hand, no differences were found in the development of bovine embryos invitro whether they were exposed to BoHV-5 reference and field strains comparing to unexposed embryos. The developed qPCR assay may have important field applications as it provides an accurate BoHV-5 US9 gene detection using a proven reference gene and is considerably less expensive than the TaqMan qPCR currently employed in sanitary programs. © 2013 Elsevier Ltd.
