Current status and some solutions for resource restoration of the abalone (Haliotis diversicolor) at Bach Long Vi National Marine Protected Area
Authors: Dong Dao Minh , Huong Tran Van , Toan Luong Huu
Published: September 2019

Variously colored abalone (Haliotis diversicolor Reeve, 1864) is the one of 22 protected species by Bach Long Vi National Marine Protected Area. In 1987, the yield of abalone was 37 tons per year, but it was reduced to 5 tons per year in 1992 and before the year of 2013, the yield is less than 1 ton per year [3]. Acording to the survey in October, 1974 the density ranged from 1 to 4 individuals/500 m2, the average for the all of island is 1.25 individuals/500 m2, the current reserve of variously colored abalone is about 0.05 tons. Some of the major causes of abalone depletion include the use of destructive fishing practices such as mines, cyanides, asynchronous development of infrastructure, and sources of pollution... Some solutions to recover the source of profit from abalone such as: The management board of Bach Long Vi National Marine Protected Area and competent authorities have to strengthen communication activities to protect the natural environment, resources as well as to have strong sanctions to strictly handle the environmental pollution activities, illegal methods of fishing. There is a need of research plan to rehabilitate Sargassum and reproduce abalone to return to natural enviroment. To invest in scientific research, to build the facilities and equipments for the management board of Bach Long Vi National Marine Protected Areas should be paid attention.

Published: September 2019

Five soft coral samples belonging to the same specimen Sinularia brassica were collected in the coastal area of Ha Long Quang Ninh, Nhat Le beach, Quang Binh, Hon Vang - Thanh Hoa and Nha Trang areas (2014–2016), these samples were examined and analyzed by total lipid content, content and composition of lipid and fatty acids. Highest total lipid content was found in the sample SHM 09 collected in Nha Trang bay (1.11%), and the lowest total lipid content was in HL-SHM 07 collected in Ha Long, Quang Ninh (0.68%).The lipid composition of samples contained basic classes such as polar lipids, sterols, free fatty acids, triacylglycerols, monoankyldiacylglycerols, hydrocarbons and waxes. In studied soft corals, there are the appearance of all fatty acids from C12 to C24. There are differences in composition and content of lipids and fatty acids in samples collected in different locations: Samples collected at Nha Trang bay contain more polyunsaturated fatty acids than the other samples collected in Ha Long, Thanh Hoa, Quang Binh. Another two samples, collected in Hon Vang (Thanh Hoa) have similar composition and content of lipid classes, the composition and content of fatty acids in total lipids. The obtained results also show the significant impact of habitat and time of acquisition on the studied subject.

Published: September 2019

The samples of vanadium substituted bismuth tungstates with a cubic structure were obtained by solid state method. The unit cell volume of the compounds slightly contracts with increasing tungsten content and in case of vanadium doping. Thermal expansion coefficient of bismuth tungstate is equal to 13×10-6 °C-1. The electrical conductivity was investigated using ac impedance spectroscopy. The results showed that the substitution of tungsten with vanadium ions increased electrical conductivity values by one order of magnitude.
Charcot's paradox
Authors: Silva Maren de Moraes e , Meira Alex Tiburtino , Walusinski Olivier , Camargo Carlos Henrique Ferreira de , Teive Hélio Afonso Ghizoni
Published: September 2019

ABSTRACT Jean-Martin Charcot (1825-1893), considered the father of modern neurology, had a particular interest in pathology and learned to value anatomical findings. Among his main contributions is the use of the anatomo-clinical method in neurology. Although described as cold and impatient in his interpersonal relations, Charcot had a great affection for animals. He had two dogs in his home, which he called Carlo and Sigurd, and a little monkey, Rosalie. Despite his fascination with neuropathology and anatomo-clinical correlations, Charcot disapproved of studies using animal species other than humans, a seemingly paradoxical attitude. As a result, Charcot's human studies resulted in important advances in neurology as, prior to his research, anatomical observations of animals were extrapolated to humans, leading to conceptual errors.

Published: September 2019

ABSTRACT Oral phase swallowing impairment in motor neuron disease (MND) is caused by tongue weakness, fasciculation and atrophy, which may compromise oral transit time and total feeding time. Objective: To describe and correlate total oral transit time (TOTT) with functional performance in MND using different food consistencies. Methods: The study was conducted on 20 patients with MND, regardless of type or duration of the disease, of whom nine were excluded due to issues on the videofluoroscopic swallowing images. The remaining 11 patients (nine men and two women) ranged from 31 to 87 years of age (mean: 57 years) with scores on the Penetration Aspiration Scale ranging from ≤ 2 to ≤ 4. The Amyotrophic Lateral Sclerosis Functional Rating Scale - revised questionnaire was applied to classify individuals according to global, bulbar and bulbar/respiratory parameters. Videofluoroscopy of swallowing using 5ml of different consistencies was performed and a quantitative temporal analysis of the TOTT was carried out with the aid of specific software. Results: There was a wide variation in the TOTT within the same food consistency among MND patients. There was a correlation between the TOTT and overall functional performance for the thickened liquid consistency (r = −0.691) and between the TOTT and bulbar performance for the pureed consistency (r = −0.859). Conclusion: Total oral transit time in MND varies within the same food consistency and the longer the TOTT, regardless of food consistency, the lower the functional performance in MND.

Published: September 2019

ABSTRACT Objective: This study aimed to analyze whether exposure to environmental enrichment (EE) during the juvenile phase of life interferes with the electrical activity of the adult rat brain. In addition, the present research also investigated whether this putative effect on brain electrical activity could be affected by prior overnutrition during lactation. Electrophysiology was measured through cortical spreading depression (CSD), a phenomenon related to brain excitability. Methods: Wistar rats were suckled in litters of either nine or three pups, forming the nourished (N) or overnourished (ON) groups, respectively. At 36 days old, half of the animals from each nutritional condition were exposed to EE. The other half was kept in the standard environment (SE). At 90-120 days of life, each animal was anesthetized for CSD recordings. Results: Overnutrition during lactation caused increases (p < 0.05) in body and brain weights. The EE decelerated CSD propagation velocity regardless of nutritional state during lactation (p < 0.001). The CSD deceleration in the N-EE group was 23.8% and in the ON-EE group was 15% in comparison with the N-SE and ON-SE groups, respectively. Conclusion: Our data demonstrated that EE exposure in the juvenile phase of the rat's life reduced brain excitability, and this effect was observed even if animals were overnourished during lactation. An EE could be considered an adjuvant therapeutic resource to modulate brain excitability.

Published: September 2019

ABSTRACT Motor impairments in stroke survivors are prevalent and contribute to dependence in daily activities, pain and overall disability, which can further upper-limb disability. Treatment with botulinum toxin A (BoNT-A) is indicated for focal spasticity and requires knowledge of biomechanics and anatomy to best select muscles to be injected in the limb. Objective: We aimed to describe the frequency of posture patterns in a Brazilian sample of stroke survivors and correlate them with recommendations of muscle selection for treatment with BoNT-A. Methods: Fifty stroke patients with spastic upper limbs scheduled for neuromuscular block were photographed and physically examined, to be classified by three independent evaluators according to Hefter's classification. Muscles that were injected with BoNT-A by their routine doctors were retrieved from medical charts. Results: Pattern III and IV were the most common (64.7%, 21.6%). We further subclassified pattern III according to the rotation of the shoulder, which effectively interfered in muscle choice. The muscles most frequently treated were shoulder adductors and internal rotators, elbow flexors and extensors, in forearm, the pronator teres and finger and wrist flexors, and, in the hand the adductor pollicis. Conclusion: Frequencies of upper-limb postures differed from previous reports. Other clinical features, besides spasticity, interfered with muscle choice for BoNT-A injection, which only partially followed the recommendations in the literature.

Published: September 2019

ABSTRACT Multiple sclerosis (MS) is an immune-mediated disease of the central nervous system. Its treatment has focused on inflammation control as early as possible to avoid disability. Autologous hematopoietic stem cell transplantation (AHSCT) has been used for treating MS since 1996, with recent decisive results regarding benefits in long-term efficacy. Five patients followed up at an MS center in Belo Horizonte, Brazil, who had relapsing-remitting MS with high disease activity, underwent AHSCT between 2009 and 2011. They were evaluated clinically, with magnetic resonance imaging, and by the EDSS every six months after transplantation, up to July 2018. The patients were four women and one man, with ages ranging from 25-50 years, and time since disease onset ranging from 4-17 years at the time of the procedure. Four patients improved, one patient was stabilized, and all patients were free of disease activity after 5-9 years. Through improving patient selection and decreasing the time from disease onset, AHSCT could stop epitope spreading and disease progression. Despite multiple other therapeutic choices being approved for relapsing-remitting MS, AHSCT continues to be a treatment to consider for aggressive MS disease.

Published: September 2019

ABSTRACT: Type of fertilizer and doses used are factors that influence the quality of pineapple fruit. This study aimed to evaluate the physico-chemical and sensorial quality of organically grown ‘Pérola’ pineapple and recommend the effective dose for best fruit quality, especially regarding sensorial acceptance. Effect of doses of 10, 20, 30, 40 and 50 t ha-1 of “bokashi” organic fertilizer on color, weight, pH, titratable acidity, soluble solids, soluble solids/titratable acidity ratio (SS/TA), vitamin C content, sensory acceptance and purchase intention was evaluated. Increasing doses of bokashi positively influenced weight and titratable acidity of the fruits and negatively affected the SS/TA ratio. Fruits produced with doses between 20t ha-1 and 40t ha-1. had good sensorial acceptance and were considered to have ideal acidity, sweetness and texture by most consumers. The authors recommend using 20 t ha-1 of bokashi, as this dose promotes the production of high quality fruits, with satisfactory SS/TA ratio and high sensorial acceptance.

Published: September 2019

ABSTRACT: This study aimed to evaluate the effect of different microwave-roasting timeson different sizes of soybean grains with black tegument to achieve the best crunchiness, flavor, and hardness. Black soybean dragées- containing a soybean core coated with layers of chocolate (dragée) - were manufactured, and their nutritional value, microbiological risk, acceptability, and consumer-purchase intentions were verified. Flavor and crunchiness of the roasted black soybeans wereonly affected by the roasting time in the microwave, whereas the hardness was only affected by grain size. The best core of the dragéewas obtainedusing grains ofsieve size 15 (large grains) roastedin the microwave for 11 min; this core presented higher frequencies for extremely crunchy notes (56%), toasted flavor (61%), and an instrumental hardness close to that of the existing commercial product (33.17 N). The manufactured dragées did not present resistant starch, anthocyanins, and microbiological risk, and they were sensorially accepted by the tasters (mean scores of 7.77 for texture and 8.36 for appearance on a scale of 1 to 9). Thus, roasted black soybean dragéeshave a high marketing potential from technological, nutritional, and sensorial points of view.

Published: September 2019

ABSTRACT: Ruminants vary their walking trajectory according to the positioning of the trees in integrated systems, which can determine the concentration of dung deposition at certain locations. The aim of this study was to map the distribution of feces and the behavior of dairy heifers in sunny and shaded areas. This experiment was carried out in Mato Grosso, Brazil, where the main grazing conditioner is shade due to the presence of trees in the pastures. Shading levels used were: full sunlight (control), moderate shade (338 trees ha−1) and intensive shade (714 trees ha−1) in randomized complete blocks. The experimental period was divided into three evaluation periods based on rainfall distribution: rainy period = December 2012; transition period = March 2013 and dry period = June 2013. Animal behavior assessments and dung distribution mapping were performed. The full sunlight system displayed a higher concentration of feces patches at sites near the gate, cow drinkers and fences opposite the gate. Heifers picked shaded places for ruminating and idleness. The major concentration was reported in the central area and under trees, in shaded systems. There were places with greater feces concentrations, but when the pasture had trees, deposition did not only happen underneath trees but also in places under their influence. The distribution was more homogeneous when trees were present in large quantities. The shaded area available in pastures affects spatial distribution of dung, stimulating uniformity.

Authors: Lambrecht Edson , Rosa Douglas Silva da , Machado Roberto Lilles Tavares , Machado Antônio Lilles Tavares , Reis Ângelo Vieira dos
Published: September 2019

ABSTRACT: Various equipment, mainly manual knapsack sprayers, are used to apply agrochemicals by smallholder farmers. They are highlighted by their versatility of use and mainly by their low cost for farmers. Few operator-related studies were reported in the literature regarding the effort required to operate the knapsack sprayer lever. Knapsack sprayers were evaluated regarding the effort required to move their hand levers, reach and maintain the 300 kPa pressure, and return to the initial position. The objective of this study was to evaluate the operator’s effort to operate the hand lever using the “Super magro” biofertilizer as fluid. It was concluded that all knapsack sprayers are within the Consolidation of Labor Laws (CLT) standards regarding the effort required to operate the hand lever. However, restrictions have been reported in some manual knapsack sprayers regarding international standards.

Published: September 2019

ABSTRACT: A 10-year-old male large mixed breed dog was presented with skin ulcers and fracture on the right hind limb caused by vehicle collision. Given required limb amputation, and as being a shelter senior dog, euthanasia was requested by the owner and a complete post-mortem examination was conducted immediately after death. Gross changes were consistent with marked bilateral nephromegaly. Histopathological examination of the kidneys revealed round cells filling blood vessels. Immunohistochemically, the round cells were positive for CD3 antibody. Based on these findings, in absence of involvement of the bone marrow and peripheral blood, and inexistence of primary extravascular masses, the tumor was classified as T-cell intravascular lymphoma. To the author’s knowledge, this is the first report describing intravascular lymphoma involving the kidneys alone in a dog.

Abstract This article parts from the importance of sugarcane based energy to the Brazilian economy and, consequently, the important role of the process that involves cutting/loading/transportation (CLT) of cane in the supplies and production cost of sugar, alcohol and its derivates. For this purpose, a study case was carried in a sugarcane factory from São Paulo state, aiming to build a proposal that could reduce the lead time in the CLT process through the analysis of the Manufacturing Critical-Path Time (MCT) of the studied industry. With the data collected in the field visits, the MCT of one tone of sugarcane during its logistic process was done. This tool revealed a long waiting time of the cane waiting to be milled in the patio of the factory. Through the theory of dynamic of the systems it was concluded that this time was high due to the variability of the field as a consequence of an inefficient use of the harvester and the logistic system of dynamic allocation of the transportation resources ahead in the harvest. To make the harvester more efficient, a reduction of 40% of the laying time “awaiting transshipment” was proposed, which would result in a save of R$ 1.172.784,00/year. For this reduction five proposals were identified to be implemented in parallel: integration of the systems of the board computer and the traffic control system; integration of the board computers of the harvester and the transports; implementation of truck filling volume sensors; focus in the management of basis leaders; and, implementation of a multitask worker.

Figuras do constrangimento: As instituições de Estado e as políticas de acusação sexual
Authors: Fernandes Camila
Published: September 2019

Resumo O artigo explora como se arquiteta um discurso de acusação em torno da sexualidade feminina “irresponsável” no interior de instituições públicas. A discussão parte de etnografia realizada em creches públicas situadas num complexo de favelas da Zona Norte (RJ). Apresento as principais etapas de acesso às vagas na instituição, assim como as estratégias mobilizadas pelas famílias para conseguir uma vaga. Acompanho de que maneira algumas situações são conduzidas a partir de uma pedagogia do constrangimento, nas quais “esporros” públicos configuram um campo de tensão entre funcionárias e mulheres usuárias dos serviços. A relação entre mulheres é marcada pela ambivalência de uma ação administrativa que, ao mesmo tempo em que acolhe as demandas pelo cuidado das crianças, é feita de censuras e constrangimentos morais. Ao final, discuto a presença de um Estado feminino, uma ação que mescla qualidades de cuidado ao lado de expedientes de cobrança e responsabilização.
As políticas dos cabelos negros, entre mulheres: estética, relacionalidade e dissidência no Rio de Janeiro
Authors: Mizrahi Mylene
Published: September 2019

Resumo O artigo é norteado pela pergunta relativa ao que haveria de distintivo em estéticas adjetivadas como negras. Em busca de uma resposta, analiso três estilos de cabelos femininos: o produzido por extensões de cabelo humano; os cabelos Black; os produzidos por extensões de cabelo sintético. Argumento a favor de uma estética relacional dissidente, que se engendra a partir de relações nem sempre harmônicas entre negras e brancas e que se constitui por sua fuga da norma - o gosto hegemônico branco - ao mesmo tempo em que elabora esteticamente sobre esta mesma norma. Junto a uma discussão englobante sobre a estética e seus poderes, analiso a dimensão performativa da raça, a noção de apropriação cultural, as noções de beleza feita e de corpo artefatual, propondo que em sociedades modernas ocidentais é por meio da apropriação das coisas ofertadas como bens e serviços de consumo que estetizamos nossos corpos e produzimos discursividades políticas.
A catarse na didática da pedagogia histórico-crítica
Authors: Duarte Newton
Published: September 2019

Resumo Segundo Dermeval Saviani, no método didático da pedagogia histórico-crítica, a catarse é o momento culminante. Este artigo explora a importância dessa categoria para a didática nessa perspectiva pedagógica, tomando como referências os estudos de György Lukács (1885-1971) e Antônio Gramsci (1891-1937) sobre o processo catártico. É defendida a interpretação de que a catarse seria um salto qualitativo no processo de ampliação e enriquecimento das relações entre a subjetividade individual e a objetividade sociocultural. Trata-se de uma transformação, ao mesmo tempo, intelectual, emocional, educacional, política e ética, que modifica a visão de mundo do indivíduo e suas relações com sua própria vida, com a sociedade e com o gênero humano.

Published: September 2019

Resumo O presente artigo traça um panorama das pesquisas que se dedicaram ao estudo sobre os temas Gestão e Trabalho no âmbito do PPGCI/UFMG, aqui subdivididas em dois subcampos, a saber: Gestão da Informação e do Conhecimento e Gestão das Unidades de Informação e Relações de Trabalho nos campos da Cultura e da Informação. No que tange à Gestão da Informação e do Conhecimento, desenvolveu-se uma leitura crítica da perspectiva a partir da qual a área vem sendo tratada no âmbito do PPGCI e apontaram-se pesquisas e perspectivas futuras. Essa análise alerta para o fato que ainda existe uma lacuna significativa nos estudos desenvolvidos relacionados à dimensão humana subjetiva do processo de gestão. Considera-se de suma importância foco nas pessoas, mais especificamente, nos aspectos comportamentais, cognitivos, simbólicos e afetivos na interação dessas com os processos organizacionais, políticos e de trabalho. O subcampo de Gestão de Unidades de Informação e Relações de Trabalho nas áreas da Cultura e da Informação tem parte substantiva de seus estudos focados na observação e análise sobre temas essenciais no contexto contemporâneo: a ocupação de postos de trabalho em unidades de informação e similares; a interação entre as demandas sociais e econômicas da ocupação destes postos de trabalho e os sistemas de formação profissional, bem como suas respostas para satisfazer às exigências mencionadas, além de focar o entorno histórico, político e econômico que permeiam essas relações. O presente artigo apresenta, como produto dessa análise, uma proposta de abordagem sobre a gestão e sobre trabalho, no contexto do PPGCI, para os próximos anos.
Memória, patrimônio e informação: diálogos em uma disciplina nuclear
Authors: Garcia Luiz Henrique Assis
Published: September 2019

Resumo A reformulação do Programa de Pós-Graduação em Ciência da Informação da ECI-UFMG envolveu a inserção de novos colaboradores e a necessidade de repensar o projeto pedagógico. Neste contexto, decidiu-se pela concepção de disciplinas nucleares, para criar um solo compartilhado que pudesse alavancar o trabalho de reflexão e investigação. No âmbito da linha de pesquisa “Memória social, patrimônio e produção do conhecimento”, envolvi-me ativamente na concepção e oferta da disciplina “Memória, patrimônio e informação”. Proponho-me aqui a examinar a proposta que a norteia, centrada no duplo intuito de oferecer uma base sólida para a compreensão da constituição e transformação dos campos que coloca em destaque e igualmente oferecer um apanhado representativo das pesquisas mais inovadoras e temas candentes na atualidade. Traçaremos uma síntese seguindo o percurso das aulas expositivas e seminários de modo a explicitar o fio condutor do curso, para concluir com uma apreciação de conjunto sobre o que foi feito na disciplina. Como mostraremos, a reformulação efetivada em 2016, portanto, não surgiu no vazio, e sim em terreno que já recebera as primeiras sementes. Uma disciplina nuclear representa o melhor adubo para que tenhamos ótimas safras no futuro próximo.

Memória Institucional e Arquivologia: uma discussão teórico-metodológica
Authors: Parrela Ivana , Nascimento Adalson
Published: September 2019

Resumo Este artigo analisa a construção do conceito de memória institucional na Ciência da Informação e, em especial, discute a memória na Arquivologia e nas instituições arquivísticas públicas e privadas. Demonstra-se que o surgimento de Centros de Memória no Brasil, na década de 1970, está associado à valorização da memória institucional, que se tornou, então, vital para as organizações. Diferente da memória organizacional, mais mutável e identificada com a eficácia, está ligada à legitimidade, à identidade e à responsabilidade histórica dos produtores nas instituições. Ela pode ser (re)construída por meio dos arquivos, ainda que não se confunda com eles.
A noção de documento no espaço-tempo da Ciência da Informação: críticas e pragmáticas de um conceito
Authors: Ortega Cristina Dotta , Saldanha Gustavo Silva
Published: September 2019

Resumo Diante da crescente discussão internacional sobre uma possível neodocumentação, em oposição a uma menor disseminação da abordagem clássica da Documentação, torna-se necessário tratar da relação entre as duas abordagens para uma compreensão da noção de documento em Ciência da Informação, bem como reconhecer a vigência de outras tradições de apropriação do conceito no campo informacional. Objetiva-se discutir a literatura sobre ‘documento’, partindo do olhar francófono (Bélgica e França, precisamente), no sentido de objeto material e simbólico, produto da prática documentária. Além disso, procura-se estabelecer relações entre esta conceituação e aquela da literatura de orientação anglo-americana denominada genericamente 'neodocumentação'. O percurso da reflexão, fruto de uma abordagem teórico-conceitual, sob uma via epistemológico-histórica e pragmática, discute a) a noção de documento proposta por Paul Otlet no início do século XX, em seguida desenvolvida por franceses, b) a produção anglófona que, em especial, a partir da década de 1990, toma por base ideias de Paul Otlet e Suzanne Briet para desenvolver suas argumentações, c) o ponto de vista de outras culturas de apropriação do conceito, como a espanhola, a italiana e a brasileira. Como apontamos conclusivos, observa-se que a construção histórica da noção de documento aponta que o mesmo é produto de ações de mediação, as quais se realizam por atividades como seleção, representação, ordenação, exposições, enquanto, sob outro ponto de vista, a abordagem dos neodocumentalistas privilegia o documento quanto às relações de poder que envolvem enquanto objeto produzido pelo homem, portanto, relações localizadas histórica, social e politicamente.
Descarga acústico-visual e temporalidades em cena: a fundação de uma tradição pela Banda Calypso
Authors: Jácome Phellipy Pereira , Prado Denise Figueiredo Barros do , Azevedo Rafael José
Published: September 2019

Resumo O objetivo deste artigo é discutir, a partir do DVD comemorativo dos 15 anos da Banda Calypso, a proposição da fundação de uma tradição de música popular pelo grupo paraense. Para isso, em um primeiro momento, retomaremos o conceito de “descarga acústica” para entender a peculiaridade do discurso do grupo frente a tradições intelectuais já estabelecidas. Em seguida, abordaremos os mecanismos visuais e sonoros acionados pela Calypso no desdobramento de matrizes temporais específicas. Isso permitirá refletir como essas temporalidades são inscritas na textualidade do próprio DVD. Entendemos que o “brega”, compreendido a partir de uma referência à matriz melodramática, consegue urdir tempos aparentemente desconexos e se torna um eixo condutor da narrativa.

Published: September 2019

Resumo Este texto examina as ações que levaram à condenação, à prisão e ao impedimento da candidatura à presidência em 2018 do ex-presidente Luiz Inácio Lula da Silva, tomando como referência o conceito de acontecimento entendido como violência, bem como as dimensões de violência na política. Os acontecimentos envolvendo Lula são identificados como práticas de lawfare, guerra jurídica com participação da mídia, que visa minar pessoas ou instituições. Teoricamente, trabalhamos com o conceito de acontecimento e com as relações entre política e violência. Como metodologia, além de revisão conceitual, recorremos a um conjunto de notícias que abordaram os acontecimentos envolvendo Lula.

The mechanism: how dental resorptions occur in ameloblastoma
Authors: Martins Giovana Gonçalves , Oliveira Ingrid Araújo de , Consolaro Alberto
Published: September 2019

ABSTRACT Knife-edge or blunt root resorptions characterize ameloblastomas and are pathognomonic for this tumor, because they differentiate ameloblastomas from simple bone cysts, odontogenic keratocysts and nasopalatine duct cysts, which do not lead to resorption of involved teeth. Despite the very high frequency and importance of these characteristics for a differential diagnosis, a microscopic examination should also be conducted before defining the diagnosis and the treatment plan for these cases. This paper describes a six-step hypothesis to explain the mechanism by which ameloblastomas promote the characteristic root resorptions found in association with these benign epithelial tumors, which have a fibrous capsule formed by islands and epithelial cords that mimic the dental lamina, invade neighboring tissues and release mediators (IL-1, EGF) of tooth and root resorption. This hypothesis may be one more explanation for the tooth resorptions sometimes found in orthodontic records, and may help differentiate the root resorptions that are specific to the orthodontic practice.

ABSTRACT Objective: The present study aims at using cone beam computed tomography (CBCT) to analyze the maxillomandibular characteristics present in adults with mandibular asymmetries and different sagittal jaw relationships. Methods: 360 patients were selected and divided into three groups (Class I, Class II, and Class III), with 120 individuals per group. The groups were then subdivided according to the intensity of lateral deviation of the gnathion point, into: 1) relative symmetry, 2) moderate asymmetry, and 3) severe asymmetry. Three planes of reference were established in the CBCT images and several measurements were taken to compare the bilateral skeletal differences between the intensities of asymmetry for the different sagittal jaw relationships. Results: When the groups were compared by the intensity of asymmetry, significant differences among patients with relative symmetry and moderate to severe asymmetry were found. This was especially noticed for severe asymmetry, suggesting that the deviation of the chin did not constitute the only morphological alteration for these patients, especially because a series of measurements showed significant bilateral differences. When comparing sagittal jaw relationships, the only significant finding was the vertical positioning of the gonion between Class II and III patients with severe asymmetry. Conclusions: When comparing the three sagittal jaw relationships with the same intensity of asymmetry, most maxillofacial aspects were quite similar. The only difference was found for patients with severe asymmetry, as the individuals with Class II showed greater bilateral difference in the vertical positioning of the gonion, when compared to patients with Class III.

ABSTRACT Objective: The purpose of this study was to establish the association between sagittal and vertical skeletal patterns and assess which cephalometric variables contribute to the possibility of developing skeletal Class II or Class III malocclusion. Methods: Cross-sectional study. The sample included pre-treatment lateral cephalogram radiographs from 548 subjects (325 female, 223 male) aged 18 to 66 years. Sagittal skeletal pattern was established by three different classification parameters (ANB angle, Wits and App-Bpp) and vertical skeletal pattern by SN-Mandibular plane angle. Cephalometric variables were measured using Dolphin software (Imaging and Management Solutions, Chatsworth, Calif, USA) by a previously calibrated operator. The statistical analysis was carried out with Chi-square test, ANOVA/Kruskal-Wallis test, and an ordinal multinomial regression model. Results: Evidence of association (p< 0.05) between sagittal and vertical skeletal patterns was found with a greater proportion of hyperdivergent skeletal pattern in Class II malocclusion using three parameters to assess the vertical pattern, and there was more prevalent hypodivergence in Class III malocclusion, considering ANB and App-Bpp measurements. Subjects with hyperdivergent skeletal pattern (odds ratio [OR]=1.85-3.65), maxillary prognathism (OR=2.67-24.88) and mandibular retrognathism (OR=2.57-22.65) had a significantly (p< 0.05) greater chance of developing skeletal Class II malocclusion. Meanwhile, subjects with maxillary retrognathism (OR=2.76-100.59) and mandibular prognathism (OR=5.92-21.50) had a significantly (p< 0.05) greater chance of developing skeletal Class III malocclusion. Conclusions: A relationship was found between Class II and Class III malocclusion with the vertical skeletal pattern. There is a tendency toward skeletal compensation with both vertical and sagittal malocclusions.

ABSTRACT Objective: The aim of this study was to compare the effects of three enamel etching modes - laser-etch, self-etch and acid-etch (5, 10 and 15 s) - on bracket bonding, using a universal adhesive. Methods: Eighty-four maxillary premolars were randomly divided into seven groups (n=12) based on the etching method and the adhesive used for bracket bonding. After water storage and thermocycling, shear bond strength was measured, and adhesive remnant index scores on debonded enamel were determined. Results: There were significant differences between the seven groups regarding bond strength values (p< 0.001). The highest values were observed in universal adhesive with laser etching group, while Transbond XT with acid or laser etching, and universal adhesive used in self-etch mode demonstrated the lowest bond strength. The universal adhesive with the three different etching times presented with statistically similar results, all showing an improvement in bond strength, compared with Scotchbond universal (SBU)/SE. Conclusions: The universal adhesive evaluated in the present study demonstrated statistically similar bond strengths to conventional orthodontic adhesive in self-etch mode. The bond strength can be improved by adding an initial acid etching or laser conditioning step, although enamel damage was observed in some cases.

RESUMO Objetivo Verificar o efeito imediato e após 15 minutos da técnica de sobrearticulação de fala em indivíduos com doença de Parkinson, submetidos à estimulação cerebral profunda em núcleo subtalâmico, nos parâmetros de voz, fala e mímica facial. Métodos Participaram 29 sujeitos com diagnóstico médico de doença de Parkinson, sob tratamento medicamentoso e submetidos à estimulação cerebral profunda em núcleo subtalâmico, com e sem reabilitação fonoaudiológica prévia. Realizou-se gravação em áudio e vídeo de amostra de fala e voz em três momentos: pré-intervenção, pós-imediato e após 15 minutos da realização individual de cinco minutos de uma sequência de exercícios de sobrearticulação de fala. As gravações foram submetidas à avaliação perceptivo-auditiva da voz e perceptivo-visual da mímica facial. Resultados A técnica produziu resultados positivos em 69% dos casos, após 15 minutos de aplicação, em relação aos demais momentos. O parâmetro que mais contribuiu para a identificação da melhor emissão na avaliação perceptivo-auditiva foi articulação (69%), significativamente maior que os demais parâmetros, exceto velocidade de fala. A análise perceptivo-visual mostrou melhora em 58,6% dos casos após 15 minutos, também significativamente melhor que os demais momentos. O parâmetro em que se observou maior proporção de melhora foi na movimentação de boca, sobrancelhas e olhos. Conclusão A técnica de sobrearticulação de fala produz efeito positivo imediato nos aspectos vocais e uma maior expressividade facial, principalmente após 15 minutos de realização.

Abstract: The objective of this work was to evaluate the use of crude glycerol as an energy source to replace corn, in diets for Nile tilapia (Oreochromis niloticus) in the fattening stage. Two hundred Nile tilapia (190±4.5 g) were distributed in 20 tanks, in a completely randomized design. The treatments consisted of crude glycerol at 0, 60, 120, 180, and 240 g kg-1, to replace the dietary levels of corn, in order to maintain a constant digestible energy. Fish productive performance and the chemical composition of the fillet were evaluated. Histological analyses of the hepatopancreas, intestine, and visceral fat were also carried out. Crude glycerol had no effect on the performance parameters; however, it caused a quadratic reduction of visceral fat. There was an increase in the moisture and a decrease in the ether extract of the fillet. A linear effect on the blood glucose levels was verified in fish fed the diet without glycerol, and the peak occurred at 90 min. There were no differences for measurements of intestinal villi height and hepatocyte area. Crude glycerol can replace corn in diets for Nile tilapia in the fattening stage, without adversely affecting fish metabolism, productive performance, or survival.

Abstract: The objective of this work was to evaluate changes in phosphorus fractions in a Humic Cambisol cultivated with vineyards, after 62 years of additional fertilization with poultry litter. Soil samples were collected from two vineyards (V1 and V2) and a forested area adjacent to them. A total of 1,365 and 910 kg ha-1 P were applied to V1 and V2, respectively, throughout the past 62 years. Samples were collected at 0-10, 10-20, 20-30, and 30-40-cm soil depths for the analysis of soil physicochemical properties. The addition of poultry litter to the soil of the vineyards increased the contents of inorganic P (Pi) in all fractions, except in the residual fraction (residual-P), mainly at the 0-10-cm soil depth, in comparison with the forested area. The addition of poultry litter as fertilizer does not affect the organic P (Po) stock in the Humic Cambisol, it only increases the Pi contents of the soil.

CANONS AND COLONIES: THE GLOBAL TRAJECTORY OF SOCIOLOGY
Authors: Connell Raewyn
Published: September 2019

Abstract The history of sociology as a field of knowledge, especially in the English-speaking world, has been obscured by the discipline’s own origin myth in the form of a canon of “classical theory” concerned with European modernity. Sociology was involved in the world of empire from the start. Making the canon more inclusive, in gender, race, and even global terms, is not an adequate correction. Important types of social knowledge, including movement-based and indigenous knowledges, resist canonization. The turn towards decolonial and Southern perspectives, now happening across the social sciences, opens up new perspectives on the history of knowledge. These can be linked with a more sophisticated view of the collective production of knowledge by the workforces that are increasingly, though unequally, interacting. Potentials for a more effectively engaged sociology emerge.
