Novel stainless steel tanks enhances coffee fermentation quality.

Fermenting in bioreactors can improve coffee quality, standardize the fermentation process, and generate specialty coffees. This work aimed to evaluate novel stainless steel bioreactors with inoculated and non-inoculated coffees processed via natural and pulped natural. Yeast and bacteria populations were evaluated and grown on Yeast Extract Peptone Glucose; De Man, Rogosa, and Sharpe; and Nutrient agar media. Volatile compounds from roasted beans were analyzed in a Gas Chromatography-Mass Spectrometry equipment, and the sensory perception was evaluated through a cup test. The mesophilic bacteria population was statistically significant in pulped natural coffee compared to yeast and lactic acid bacteria. Furans had the highest concentration among the chemical groups. Beverage inoculated with CCMA 0535 presented the highest SCA score. Prune, peach, and floral attributes were only perceived in Nat CCMA 0535. The sensory perception indicated that the inoculated yeasts modified the flavor attributes, enhanced the quality, and increase their SCA scores.

Influence of fermentation conditions on the sensorial quality of coffee inoculated with yeast.

Fermentation is one of the post-harvest steps that influence coffee quality. This work evaluated the effect of Saccharomyces cerevisiae (CCMA 0543) and Torulaspora delbrueckii (CCMA 0684) inoculation on the quality of natural and pulped natural processed coffee in different producing regions. Yeast populations were assessed by the real-time polymerase chain reaction. Volatile and nonvolatile compounds were evaluated by gas chromatography-mass spectrometry and high-performance liquid chromatography, respectively. S. cerevisiae was predominant during spontaneous (average of 4 log cells/g) and inoculated (average of 7 log cells/g) fermentations in both processes. T. delbrueckii showed a similar population (3.79 log cells/g) in all assays. Glucose and fructose were the most detected sugars in coffee beans. Succinic acid was found at the end of the fermentative process. The lactic acid concentration was inversely proportional to ethanol concentration. Pyrrole and furan, which are volatile groups, allowed to differentiate the coffee processing methods. Yeast inoculation modified the sensorial profile and increased the coffee beverage scores by up to 5 points. S. cerevisiae inoculation was most suitable for pulped natural coffee, and T. delbrueckii inoculation showed the best performance in natural coffee.

Tratamento de má oclusão Classe II com propulsor mandibular em paciente adulto ­ relato de caso / Class II malocclusion treatment with mandibular protractor in adult patient ­ case report

Resumo A má oclusão de Classe II de Angle é uma das alterações mais frequentes na Ortodontia, podendo ser caracterizada por prognatismo maxilar, deficiência mandibular ou até pelo envolvimento de ambos. Em grande parte dos casos, a deficiência mandibular está presente em detrimento do desenvolvimento do osso maxilar e dentre os principais tratamentos se destacam aqueles que visam a correção de problemas esqueléticos através de dispositivos de propulsão mandibular. O objetivo deste artigo é descrever um relato de caso de paciente jovem com a utilização do Propulsor Mandibular PowerScope™ 2 no intuito de corrigir a Classe II dentária, a linha média inferior e a sobremordida. Concluiu-se que tal dispositivo é uma excelente opção para correções de maloclusões dentárias de Classe II em pacientes adultos, com rapidez, conforto, higiene, controle e facilidade na sua instalação e ativação, bem como mínimo efeito colateral nas arcadas.

Abstract Angle Class II malocclusion is one of the most frequent changes in Orthodontics, it can be characterized by maxillary prognathism, mandibular deficiency or even the involvement of both. In most cases, mandibular deficiency is present to the detriment of the development of the maxillary bone and, among the main treatments stand out those that aim to correct skeletal problems through mandibular propulsion devices. The purpose of this article is to describe a case report of a young patient using the PowerScope™ 2 Mandibular Protractor in order to correct dental Class II, lower midline and overbite. It was concluded that this device is an excellent option to correct Class II dental malocclusions in adult patients, with speed, comfort, hygiene, control, and easy installation and activation, as well as minimal side effects in the arches.

O cotidiano da criança na instituição de ensino: espaço e tempo disponível para atividades lúdico-motoras / The daily life of children in the Education System: space and time available for activities playful­motor

O objetivo desse estudo foi observar o cotidiano da criança na Instituição de Ensino Infantil e verificar o espaço e tempo disponível para engajar em jogos locomotores. Trata-­se de um estudo do tipo observação in loco não participativa. A amostra foi composta por 18 Instituições de Ensino Infantil pertencentes a quatro municípios da Região Metropolitana de Campinas (RMC) que atende crianças comidades entre 4 e 6 anos. O jogo é observado como uma atividade fundamental para o desenvolvimento da criança. Todavia, verificou-­se que as Instituições de Ensino não têm atendido a criança em seu direito ao jogo. O problema em torno do jogo na escola perpassa diferentes dimensões, desse modo, exigindo outros estudos...

This study aimed to observe the daily life of children in the Child Education Systemand assess the space and time available for their involvement in locomotor games. The study was a non­participatory on­site observation. The sample consistedof 18 children educational institutions from four municipalities in the Campinas Metropolitan Region (RMC), which serve children aged between 4 and 6 years. Playing is a key activity to the child's development; however, we found out that the schools have been depriving children of their right to play. This issue permeates different dimensions, there fore requiring further research...
