Estrategias combinadas para la obtención de un vino Tannat con un contenido moderado de alcohol

Resumen En este trabajo se buscó a través de la combinación de 2 estrategias reducir el contenido de alcohol en vinos de la variedad Tannat. La primera estrategia consistió en el screening dentro de clones uruguayos de Tannat Con este fin se muestrearon durante tres vendimias consecutivas 10 clones uruguayos de Tannat y se utilizó como referencia el clon francés 717 en viñedos. De los clones estudiados 4 presentaron durante la vendimia 2023 un contenido significativamente inferior de alcohol que el clon 717, manteniendo los componentes responsables de su calidad sensorial (aromas glicosidados, antocianos totales). Mientras que la segunda estrategia fue realizar un screening de levaduras no-Saccharomyces nativas aisladas de viñedos uruguayos para utilizar en conjunto con la cepa Saccharomyces cerevisiae Lalvin BM4x4 Lalleman (utilizada como referencia para vinificar vino Tannat). Se estudió el comportamiento de 4 géneros de levaduras (Candida zemplinina, Metschnikowia pulcherrima, Metschnikowia fructicola y Hanseniaspora uvarum), en microvinificaciones en símil vino. Estas estrategias fueron seleccionada por que además de permitir la reducción de alcohol en vinos Tannat en forma conjunta le aportan una identidad propia de nuestro país

Correlation Between Fine Particulate Matter, Weather, and Traffic Conditions on Taft Avenue during the Covid-19 Pandemic

In light of the COVID-19 pandemic, an Enhanced Community Quarantine (ECQ) was imposed from August 6 to August 20, 2021 in the National Capital Region of the Philippines. With an imposed lockdown, the air pollution levels in a metropolitan area may have decreased. Hence, the study focused on finding a correlation between the air pollution concentrations, weather, and traffic conditions on Taft Avenue from August 1 to 14 and September 5 to October 2, 2021. To do so, the researchers have utilized real-time data on fine particulate matter (PM2.5), weather, and traffic conditions using Google Maps, Weather Underground, IQAir, and from the Air Quality Monitoring System (AQMS) of the Environment and Remote Sensing Research Laboratory (EARTH) located at De La Salle University. Most correlations between PM2.5 concentrations, weather parameters, and traffic conditions were found to have low to moderate correlation with each other. There were also differences between the correlation of PM2.5 concentrations from IQAir and EARTH with traffic and weather parameters which might be due to the fact that the location of their stations vary

Diferenças quanto à escolaridade em adultos no desempenho no teste de cancelamento dos sinos Differences regarding education in adults in the bells test

O papel de variáveis sociodemográficas na cognição humana, em especial da escolaridade, vem sendo estudado em indivíduos saudáveis. Esta pesquisa objetivou verificar se há diferenças entre grupos de diferentes níveis educacionais no processamento atencional visual avaliado pelo Teste de Cancelamento dos Sinos. Participaram 124 adultos jovens, distribuídos em três grupos, 5-8, 9-11 e 12 ou mais anos de educação formal, emparelhados por idade. As variáveis de acurácia e tempo, assim como os resultados qualitativos de estratégias utilizadas, foram comparados entre grupos (ANCOVA One-Way e Qui-quadrado). Observou-se uma discrepância entre dados quantitativos e qualitativos. Os grupos de diferentes escolaridades não se diferenciaram entre si quanto a acurácia e tempo; houve, porém, diferenças significativas quanto à distribuição de participantes por coluna em que o primeiro sino foi cancelado e pelas estratégias de cancelamento utilizadas. Novos estudos são relevantes com grupos de diferentes idades e com populações clínicas neurológicas e/ou psiquiátricas.<br>The role of socio-demographic variables on human cognition, particularly education, has been studied in healthy individuals. This research aimed to verify if there are differences among educational groups regarding the visual attentional processing assessed by means of Bells Test. The sample was comprised of 124 young adults, divided into three groups, 5-8, 9-11 and 12 or more years of formal education, matched by age. Accuracy and time data were analyzed by one-way ANCOVA and the qualitative results on strategies were compared between groups by Chi-square. The results showed a discrepancy between the quantitative and qualitative analysis. There were no quantitative differences among educational groups regarding accuracy and time variables. However, significant differences were found in the distribution of participants by chosen column where the first bell was canceled and the used strategies of cancellation. Further studies are relevant including different age groups and clinical samples with neurological and/or psychiatric disorders
