CARACTERIZAÇÃO DO PADRÃO DAS CHUVAS OCORRENTES EM LAVRAS, MG Adão Wagner Pêgo Evangelista; Luiz Gonsaga de Carvalho; Daniel Teixeira BernardinoDepartamento de Engenharia, Universidade Federal de Lavras, Lavras, MG, awpego@ufla.br 1 RESUMO Em razão da variação da intensidade da precipitação pluvial durante a sua ocorrência, desenvolveu-se este trabalho com o objetivo de estudar os padrões de chuvas erosivas naturais verificadas em Lavras, MG, e estimar o período de retorno das chuvas em três padrões propostos. Para isto utilizou-se uma série histórica de dados pluviográficos para o período de 1987 a 1989 e 1992 a 2003, correspondente à Estação Climatológica Principal 83687 (INMET). As chuvas foram classificadas em padrão avançado, intermediário e atrasado, de acordo com a posição do pico de máxima intensidade e, posteriormente, foram calculadas as intensidades máximas de chuva para várias durações e períodos de retorno. Também foram construídas curvas de intensidade, duração e freqüência para os padrões de chuva supracitados. Com base nos resultados, pode-se concluir que o padrão de chuvas avançado se destacou em todos os parâmetros analisados, seguido em ordem decrescente pelo padrão de chuvas intermediário e atrasado. O padrão avançado correspondeu a 68% do total de chuvas analisadas, o intermediário com 22% e o atrasado com 10%. UNITERMOS: período de retorno, intensidade de chuva, perfil de precipitação.

RAINFALL PATTERN CHARACTERIZATION IN LAVRAS, MG 2 ABSTRACT Due to rainfall intensity variation during its occurrence, this experiment was carried out in order to study the natural erosive rainfall patterns, in Lavras, Minas Gerais, Brazil, and estimate the rainfall return period for the three proposed patterns. Climatic historic pluviograph data from 1987 to 1989 and from 1992 to 2003 were used. Rainfall events were classified as advanced, intermediate and delayed, according to their maximum intensity peak position and afterwards, the maximum rainfall intensity was calculated for several durations and return periods. Intensity, duration and frequency curves for the three above mentioned patterns were also calculated. It was concluded that the advanced pattern of rainfall was more significant than all the analyzed parameters, followed by the intermediate one and the delayed pattern. The advanced pattern corresponded to 68% of the total analyzed rainfall, the intermediate one to 22% and the delayed pattern to 10% KEYWORDS: return period, rainfall intensity, precipitation profile.

Estabeleceu-se a cultivar EPAGRI 109 em unidades de solo com texturas areia-franca, franca e argilo-siltosa. Utilizaram-se calhas Parshall e sifões de plástico como instrumentos para medição e aplicação de água aos tabuleiros. O período de irrigação do cultivo de arroz para as condições de solo e clima no perímetro irrigado Morada Nova situa-se em torno de 120 dias, período este que deve ser tomado como referência para o planejamento da irrigação. A eficiência de uso da água para os solos de textura leve apresentou valor médio de 0,2 kg.m-3; já para os solos de textura pesada, de 0,43 kg.m-3. A eficiência de aplicação de água na unidade textural argilo-siltosa, solo adequado ao cultivo de arroz apresentou um valor médio de 77%. Na unidade textural areia franca, porém, solo não recomendado para o cultivo do arroz, a eficiência de aplicação foi apenas de 38%. UNITERMOS: (Oryza sativa, L., irrigação, eficiência de aplicação.

A construção viral da realidade: ciberpopulismos e polarização dos públicos em rede
Authors: Baldi Vania 
Published: October 2018

O presente artigo visa analisar os desafios sociotécnicos e políticos representados pela fragmentação e polarização dos discursos públicos que atravessam os diferentes espaços info-comunicacionais. A opinião pública perspetiva-se como balcanizada por conflitos permanentes entre interpretações e tomadas de posição que dizem respeito a temas de relevância pública. Destaca-se como o intuito desses discursos não é o de gerar um diálogo entre interlocutores para chegar a uma plausível interpretação da realidade, mas o de tornar virais convicções preestabelecidas e assim acentuar o afastamento entre os grupos intervenientes.
Nesta perspetiva, afirma-se como os fenómenos sociais ficam transfigurados e pulverizados em micronarrativas radicais, abstratas e incoerentes, deturpando as noções de realidade e verdade. Dentro deste cenário é analisado como os media digitais, através dos seus diferentes filtros, algoritmos, affordances, bots, trolls etc., proporcionam uma intensificação e uma expansão da desordem informacional, que por sua vez se reflete numa ameaça para a vida democrática. Nesse sentido, a distorção dos conteúdos e das formas comunicativas são consideradas como emblemáticas e reforçativas das caraterísticas e tendências principais dos atuais movimentos populistas.
Comparando e articulando um conjunto de investigações, dados, hábitos e acontecimentos relativos ao fenómeno sociopolítico do populismo e ao tipo de literacia tecno-cultural predominante na infoesfera pretende-se enquadrar e analisar, através dum prisma interdisciplinar, os desafios societais representados pela emergente sobreposição de questões políticas, tecnológicas e culturais. Se apresentam no fim do texto iniciativas culturais, tecnológicas, jornalísticas e jurídicas que apontam para uma resposta construtiva e criativa à tendência sociotécnica e sociopolítica analisada ao longo do artigo.

Objective This retrospective study was conducted to analyze changes in the maxillary permanent molars after monobloc advancement with rigid external distraction (RED). Setting University hospital–based craniofacial center. Materials and Methods Fourteen patients, three in primary, eight in mixed, and three in permanent dentition underwent monobloc advancement with RED. After a latency period of 6 days, distraction was carried out for 18 days. Lateral cephalometric radiographs were taken before surgery (T1) and an average of 3.72 months after the removal of the distractor (T2). Panoramic radiographs were taken at T1, T2, and T3 (an average of 14.87 months after RED removal), to search for surgical tooth trauma, arrested crown/root development, impaction, tooth germ displacement, dilacerations, and other possible dental abnormalities. Vertical and horizontal displacement and angulations of the permanent maxillary molars were evaluated before and after surgery. Statistics A paired t test was used to analyze significant changes in molar position after distraction. Results and Conclusions Distraction created posterior arch length with significant horizontal forward movement of the first and second molars ( p < .05) and minimal vertical displacement ( p > .05). The procedure disrupted the development of one of the first molars, three of the second molars, and two of the third molars. Incidence of molar damage was increased in patients operated on during primary dentition. Careful surgical technique during pterygomaxillary disjunction, especially in young children, and long-term radiographic follow-up of maxillary molars is strongly recommended.

Objective: The purpose of this study was to analyze the three-dimensional configuration of the premaxilla, vomer, and lateral segments in bilateral cleft lip and palate (BCLP) infants and to investigate the early changes in the configuration following one- and two-stage cheiloplasty. Methods: This study consisted of 10 complete BCLP infants. One-stage operations were performed in five patients according to Manchester's method at 4 months of age. Two-stage operations were done for the remaining five patients using a triangular flap according to Tennison's method, at 4 and 8 months of age. Serial plaster models before and after the cheiloplasty were measured with a computer-controlled, highly accurate, contact-type measuring apparatus. Temporal changes in the configuration and form of the premaxilla were observed using an automatic superimposition method. The inclination and deviation of the vomer were evaluated using an approximation technique to a straight line with least squares. The distance between the lateral segments and a three-dimensional coordinate of the incisal point were also measured. Results and Conclusions: The following differences in palatal configuration between the one- and two-stage cheiloplasties were observed: 1) In the two-stage group, the premaxilla shifted toward the cleft edge where the cheiloplasty was performed in both first- and second-stage operations. After the two-stage operation, the premaxilla did not shift greatly, and the premaxilla in cases 4 and 5 shifted downward and toward the cleft edge of the lateral segments where the first operation was performed. Protrusion of the premaxilla remained in the two-stage group. 2) In the one-stage group, the premaxilla in case 4 descended downward and backward without twisting or bending. The premaxillae of the other patients descended downward with twisting and bending. 3) Patients in the two-stage group had a stronger tendency toward medial collapse of the lateral segments than did those in the one-stage group.

Published: October 2018

Objective: A method for the quantitative and qualitative analysis of the facial soft-tissue profile has been developed, and applied to analyze the pretreatment lateral head films of 240 orthodontic patients aged 8 to 14 years. Methods: Patients were subdivided for sex, age, and skeletal class. To standardize for different facial sizes, soft-tissue profiles from nasion to pogonion were traced in polar coordinates without modifications of facial shape, and standardized for an equal skeletal vertical dimension. Results: The method allowed a simple and rapid quantitative evaluation of soft-tissue profiles during facial growth. An approximate evaluation of the soft-tissue thickness at nose, lips, and chin was also possible. No particular mathematical knowledge was required at any step of the analysis. Conclusions: Facial soft-tissue size and shape were influenced by age and sex, and to a minor extent by skeletal class.

Objective To align the protruding premaxilla in infants with bilateral cleft lip and palate (BCLP), an intraoral appliance (i.e., Hotz plate) and an extraoral appliance consisting of a band covering the head and elastics are used as a presurgical orthopedic treatment in our clinic. The aim of this study was to analyze the configuration and position of the premaxilla and the vomer in infants with BCLP and to investigate the factors generating deviation and bending of the vomer and twisting of the premaxilla. Patients Palatal casts were obtained serially from 10 infants with complete BCLP from 1 to 3 months of age. Measurements These casts were automatically measured using a highly accurate contact-type measuring apparatus. After three-dimensional wire frame models generated from the serial casts were automatically superimposed, the magnitude and direction of the shift were calculated. A discriminant analysis was used for investigation of predictor variables generating the twisting or bending vomer. Results and Conclusions The vomer was found to be bent in two infants and the premaxilla was twisted in three infants. In the infants whose vomers were bent, the magnitude of the posterior shift of the premaxilla was greater than that of the inferior shift. A discriminant analysis indicated that at 1 month of age, a greater inclination and a smaller deviation of the vomer and a longer distance between the cleft edges of the lateral segments had a tendency to be associated with bending of the vomer or twisting of the premaxilla.

Objective In this study, researchers evaluated the otologic and audiologic status of 112 children with repaired cleft lip and palate who had received primary palatal repair by means of Frolova palatoplasty, a surgical technique developed by Dr. Larisa Y. Frolova, founder and director of the National Pediatric Center for Congenital Maxillofacial Pathology, Moscow, Russia. Design Results of hearing thresholds and tympanograms for these Russian children were compared with data previously reported from a group of 48 children and adults with repaired cleft lip and palate at the University of Florida Craniofacial Center, Gainesville, Florida. Results There were no substantial differences in hearing thresholds between the two groups, which was surprising in view of the vast differences between middle ear management techniques used in Russia and the United States. Conclusions Considering these findings and the growing body of literature favoring a more conservative approach to the management of middle ear effusion in infants with cleft lip and palate, a reexamination of otologic strategies in the United States seems advisable.

Objective To evaluate the stature of Russian children with cleft lip and palate (CLP). Design One hundred twelve Russian children predominantly with repaired unilateral CLP 4 through 10 years of age underwent studies including height measurement, physical examinations, and record review. Children with health concerns that could affect growth were excluded. U.S. growth data from the National Center for Health Statistics (NCHS) and Russian parental heights were used in the absence of Russian growth norms. Results Based on U.S. norms, the distribution curve for heights for the Russian children was largely confined to the + 1 to −1 standard deviation (SD) range. Sixty-two percent of the Russian children had heights below the 50th percentile for American female and male children of the same age. The proportion of children found outside the + 1 to −1 SD range approximated the proportion expected statistically for the general population, with 14.4% < –I SD (16th percentile) and 12% > +I SD (84th percentile). A total of 3.6% of the children ranked below the third percentile, which is close to the expected 3%. Russian parents' (n = 209) mean heights were 0.5 SD below NCHS's 50th percentile values for adults. Conclusion These results indicate that there is no increased risk of true short stature in 4- to 10-year-old Russian children with repaired CLP.

Published: October 2018

Objective The palatal aponeurosis is a controversial structure, both in terms of its anatomy and its function. This article points out a pathologic finding in the cleft palate condition that has not been previously described. Design and Method By means of surgical dissections, this study demonstrates in detail that the palatal aponeurosis exists even in cleft palates, but it is disrupted, malpositioned, and folded in two layers. Patients This dissection method has been performed on more than 150 patients with cleft of the hard and soft palate, with or without cleft of the lip and alveolus. At the time of operation, the children were between 6 and 8 months of age. Results It is possible to dissect the two layers of the palatal aponeurosis, to unfold the aponeurosis, and to form a tough tendinous plane. Conclusion For a functional physiologic reconstruction of the cleft palate, it is necessary not only to reconstruct the levator veli palatini and palatopharyngeus muscle slings, but also to approximate and suture the fibers of the palatal aponeurosis to the corresponding fibers of the opposite side after unfolding them in a medio-dorso-cranial direction. In this manner, a continuous palatal aponeurosis can be created, which subsequently can serve as a transmitter of the muscle forces.

Objective The aim of this study was to evaluate the healing of artificially induced bony defects in dogs by means of demineralized allogenous bone powder (DBP) implants covered with polyhydroxy lactic acid (PLA) casts compared with DBP implants without the casts. Design Prospective animal study. Setting Research university. Sample Following a pilot study in which two dogs were used, four mongrel dogs between the ages of 18 and 24 months and weighing approximately 20 kg were used as subjects. Interventions Each experimental animal had bilateral maxillary alveolar clefts created. In a later procedure, each defect was repaired with a DBP implant, half of which were covered with a PLA96 matrix. Each animal also had a circular defect created in each parietal bone that was immediately covered with DBP implants, half of which were similarly covered with a PLA96 disk. Main outcome measure Repeated technetium-99m methylene-diphosphate (99mTC MDP) uptake measurements were performed to evaluate bone metabolism during the healing period, while at relevant intervals, radiographs were taken of the healing alveolar cleft defects to register bone repair. After 1 year, the animals were euthanized for macroscopic and histologic evaluation. Results Histologically, the grafts covered with PLA96 were at a more advanced stage of healing than those without, and the cranial defects similarly were more advanced in the healing process than the alveolar defects. Uptake of 99mTC MDP into the cranial implants was at its maximal level after 1 week and then gradually decreased until, after 7 weeks, it was not significantly different from zero. Cranial defects covered with a PLA96-enhanced implant showed a mean maximum count rate of 275, while the plain DBP side showed a mean maximal count rate of 150. Alveolar defects with the plain DBP implant showed a maximum count rate in the first week; those with the PLA96 enhanced implant showed maximum uptake during the second week. On both sides, there was a gradual decrease to the base value in the seventh week. The mean maximum count on the PLA96-enhanced side was 285, while on the plain DBP side, the corresponding value was 320. Conclusion Although an advantage of the combination was established for parietal cranial defects, no advantage was seen for alveolar cleft defects in this experimental setup.

Published: October 2018

Objective Investigated mental development in infants and toddlers with cleft lip and/or palate (CLP). Design This was a retrospective analysis of developmental scores on qualified children between 4 and 36 months of age. Cross-sectional analysis included children in four age groups (6, 12, 18, and 24 months); longitudinal analysis included children at mean age 9.1 (range = 4 to 15) months at Time 1 and 24 months (range = 16 to 36) at Time 2. Participants Cross-sectional analysis included 180 children (59% male participants) in four diagnostic groups (cleft lip only [CL], cleft lip and palate [CLP], cleft palate only [CP], and Pierre Robin). The longitudinal sample included 85 children (64% male children) in the same diagnostic groups. Main outcome Measures Mental Scale (MDI) of the Bayley Scales of Infant Development. Results Mean MDIs were in the average range but decreased significantly between youngest and oldest groups in both cross-sectional (F(3,179) = 4.9, p < .01) and longitudinal samples (F(1,84) = 6.87, p < .01). There was a significant difference among cleft types (F(3,179) = 3.5, p < .025). Infants with CL obtained the highest scores, and infants with Pierre Robin Sequence obtained the lowest. Perceptual-motor development in the first year of life was predictive of developmental status at age 2. Conclusions The number of children with CLP who may be at risk for developmental problems during the second year of life is greater than would be expected. Children at greatest risk may demonstrate early delays in acquisition of perceptual-motor skills during the first year of life.
