13. Algoritmos de decodificação abrupta para códigos LDGM / Hard decision algorithms for LDGM Codes
Desde que Gallager introduziu o algoritmo de decodificação Bit-Flipping (BF) com decisão abrupta para códigos Low Density Parity Check (LDPC), outras duas variantes foram propostas por Sipser e Spielman para os códigos conhecidos como "Expander Codes". Posteriormente, uma versão da decodificação BF por decisão suave conhecida como decodificação Mo

14. Corrosion in Haas expanders with and without use of an antimicrobial agent: an in situ study
OBJECTIVES: The purpose of this study was to evaluate in situ the occurrence of corrosion in the soldering point areas between the wire, silver brazing and band in Haas expanders. MATERIAL AND METHODS: Thirty-four 7-12-year-old patients who needed maxillary expansion with a Haas expander were randomly assigned to two groups of 17 individuals each, according

15. Estudo prospectivo das alterações cefalométricas verticais dento-esqueléticas em pacientes com atresia maxilar e mordida aberta anterior produzidas por dois tipos de disjuntores palatinos: bandado e colado / Prospective study of dental skeletal vertical cephalometric alterations in patients with maxillary constriction and open bite produced by two kinds of palatal appliances: banded and bonded
The fast expansion of the maxilla is a treatment quite used in Orthodontics, for the correction of transversal discrepancies and it provides a better adaptation of the tongue due to the bone increase of the palatal arch, as well as a better nasal breathing. However, the vertical dental skeletal alterations produced by this therapeutic method are questioned.

16. SUBSTITUIÇÃO PARCIAL DO MILHO PELO SORGO E DA PROTEÍNA DO FARELO DE SOJA PELA PROTEÍNA DO FARELO DE CAROÇO DE ALGODÃO EXTRUSADO EM RAÇÕES PARA FRANGOS DE CORTE
This work had duration of 35 days and was lead in the Department of Zootecnia of the Agricultural Federal University of Pernambuco with the objective to evaluate the use of sorghum and of the expander cottonseed meal in substitution to the corn and soybean meal. 300 chickens had been used, males, of the commercial mark Ross, in the experimental period of 7 u

17. ANÁLISE NUMÉRICA E EXPERIMENTAL DO COMPORTAMENTO DE EXPANSORES DE PELE SOBRE BASE ELÁSTICA / NUMERICAL AND EXPERIMENTAL ANALYSIS OF THE BEHAVIOR OF SKIN EXPANDERS ON ELASTIC FOUNDATION
Despite the knowledge of the behavior of structures on elastic base being important for the engineering of general form, the motivation of this work is focused in the Biomechanics, in our works involving the group of research of the Clinic of the Dr.Ivo Pitanguy and the Saint Casa de Misericórdia. In recent thesis of Dsc., a modeling of the surgical techniq

18. Análise dos principais efeitos na propagação de sinais ópticos no espaço livre revestida de uma plataforma numérica eficiente / Análise dos principais efeitos na propagação de sinais ópticos no espaço livre revestida de uma plataforma numérica eficiente
Esta dissertação apresenta os elementos-chaves de um enlace óptico, no espaço livre. Primeiramente, é feita uma análise do enlace no vácuo e, posteriormente, são introduzidos os efeitos causados pela propagação pela atmosfera terrestre. Ao longo deste trabalho, ficará demonstrado como obter os principais parâmetros e os modos de propagação do f

19. ANÁLISE NUMÉRICA E EXPERIMENTAL DO COMPORTAMENTO DA PELE HUMANA SOB EXPANSÃO / NUMERICAL AND EXPERIMENTAL ANALYSIS OF THE BEHAVIOR OF THE HUMAN SKIN UNDER EXPANSION
A modelagem de materiais biológicos para o entendimento de diversas práticas cirúrgicas na medicina, tem se mostrado a cada dia mais importante. Na cirurgia plástica, reparadora ou estética, o conhecimento do comportamento da pele humana, in vivo, é de fundamental importância nos processos cirúrgicos. Nos últimos anos, mais precisamente desde 1957,

20. Cephalometric study through lateral cephalograms of dentoskeletal changes following by the use of three maxillary expansion appliances: bonded, Haas and Hyrax / Estudo cefalométrico em norma lateral das alterações dentoesqueléticas produzidas por três tipos de expansores: colado, tipo Haas e Hyrax
The objective of this cephalometric study was to compare, through lateral cephalograms, the dentoskeletal changes following the use of three types of rapid maxillary expansion appliances. The sample consisted of 69 lateral cephalograms taken from 23 subjects, 15 females and 8 males, with an initial age ranging from 9 years 8 months to 15 years 5 months, pres

21. ANÁLISIS NUMÉRICA DE MEMBRANAS Y BIOMEMBRANAS VISCOELÁSTICAS SUBMETIDAS A EXPANSIÓN ASIMÉTRICA / ANÁLISE NUMÉRICA DE MEMBRANAS E BIOMEMBRANAS VISCOELÁSTICAS SUBMETIDAS À EXPANSÃO AXISSIMÉTRICA / NUMERICAL ANALYSIS OF VISCOELASTIC MEMBRANES AND BIOMEMBRANES SUBJECTED TO AXIALLY-SYMMETRIC EXPANSION
Tissue expansion is a well-known plastic surgery technique, based on the ability of biologic membranes to increase its surface area when a deformation is imposed. It is used to repair a wound area (scars, burns), to remove tattoos, in breast reconstruction, etc. This involves inserting a silicon-rubber prosthesis (expander) in its collapsed state under the s

22. Estudo de produção enzimatica da dextrana clinica
This study consists of the "in vitro" production of clinical dextran from sucrose using the enzyme dextransucrase obtained from Leuconostoc mesenteroides NRRl B512-F. Clinical dextran, whose average molecular weight is 40,000 daltons, is extensively used as a volume expander of human blood. The enzyme was produced by fermentation; purified by ultracentrifuga

23. The role of joint receptors in human kinaesthesia when intramuscular receptors cannot contribute.
1. Kinaesthetic acuity was tested at the distal interphalangeal joint of the middle finger when the hand was postured so that the joint was effectively disengaged from its muscular attachments. Subjects were required to detect the direction of 5 deg movements applied at different angular velocities from a mid-position under control conditions, after intra-ar

24. Superior oblique tendon lengthening for acquired superior oblique overactions.
Two patients who presented with compensatory head postures and diplopia are described. They both had marked unilateral superior oblique overaction, in one patient due to a large, incomitant skew deviation. Each underwent a superior oblique tendon lengthening procedure using a segment of silicone 240 retinal band as an expander, in combination with a contrala
