Efecto de la melaza de caña tratada con ácido sulfúrico en la produccion de celulosa por Gluconacetobacter xylinus IFO 13693

En este estudio se evaluó el efecto de la melazatratada con ácido sulfúrico (MZA-TR) y delas condiciones del cultivo (estático) sobrela síntesis de celulosa por Gluconacetobacterxylinus IFO 13693, para ello, se uso unreactor con 0,2 litros de medio de cultivo, conconcentraciones iniciales de 13,3 % y 26,6% de MZA-TR en el medio de cultivo a pH5,6. El volumen del inóculo fue del 10 % delvolumen total del medio; el proceso se realizóa temperatura ambiente (30 °C), con tiemposde incubación de 3, 7, 14, 21 y 28 días.Además, se evaluaron distintos parámetrosfisicoquímicos y mecánicos de la celulosa.El grosor de la película de celulosa presentóun máximo de 2,5 cm, siendo el mejorresultado obtenido, en comparación conanteriores reportes en la literatura. Tambiénse encontró que al usar MZA-TR en el mediode cultivo hay un incremento considerablede la producción de celulosa en estático a los28 días de incubación. Finalmente se observóque el consumo de glucosa y de fructosadisminuye durante la síntesis de celulosabacteriana (CB); durante los 3 primeros díasde incubación se observó el máximo descenso,lo que permite correlacionar la producciónde CB con el consumo de medio. Laconcentración de 13,3 %, presenta los mejoresresultados en los parámetros de velocidad decrecimiento microbiano, cantidad y calidad dela celulosa producida

EVALUACIÓN DE CINCO MÉTODOS PARA EL PRONÓSTICO Y EL ANÁLISIS DE TENDENCIA DE LA PRODUCCIÓN AGRÍCOLA DE PANAMÁ: : UNA HERRAMIENTA PARA LAS INSTITUCIONES Y EMPRESAS DEL SECTOR

As an orientation for agricultural science managers and practitioners to improve budget planning and projected financial statements, five forecasting methods and the trend of linear regression, over a time series, for 30 agricultural crops in Panama were analyzed. The five forecasting methods applied were Simple Moving Average (SMA), Weighted Moving Average (WMA), Exponential Smoothing (SE), Simple Linear Regression (SLR) and Polynomial Regression (PR) and the only trend method used was SLR. The data was run in Excel software. The results of the basic statistics (see table 1) showed that, of 30 items analyzed in 2019, in 16 cases production was below the average of the historical series. Table 2 shows that, of the 30 items predicted, 6 cases corresponded to the SMA, 14 cases to the WMA, 9 cases to the SE and in one case to the PR method.  In the trend analysis, for after 2019, of the 30 cases analyzed, 19 items showed a tendency to decrease, 9 showed an increase and two to were predicted to maintain constant production.  It is concluded that the forecasts to produce agricultural crops may vary from one method to another, depending also on addition to the data and time, a high coefficient of determination of the regression model, a result in positive real numbers and the lowest percentage error of absolute deviation.Como una orientación para que los administradores y profesionales de las ciencias agrícolas mejoren la planificación de presupuestos y estados financieros proyectados, se analizaron cinco métodos de pronósticos y la tendencia de la regresión lineal, en una serie de tiempo, para 30 cultivos agrícolas en Panamá. Los cinco métodos de pronósticos aplicados fueron el Promedio Móvil Simple (PMS), el Promedio Móvil Ponderado (PMP), la Suavización Exponencial (SE), la Regresión lineal simple (RLS) y la Regresión Polinómica (RP) y el único método de tendencia utilizado fue el RLS. Los datos se corrieron en el software Excel. Los resultados de las estadísticas básicas (ver tabla1) mostraron que, de 30 rubros analizados en el 2019, en 16 casos la producción estuvo por debajo del promedio de la serie histórica. En la tabla 2 se observa que, de los 30 rubros pronosticados, 6 casos correspondieron al PMS, 14 casos al PMP, 9 casos a la SE y en un caso al método de la RP.  En el análisis de tendencia, para después del año 2019, de los 30 casos analizados, 19 rubros mostraron tendencia al decrecimiento, 9 mostraron al incremento y dos a mantener la producción constante.  Se concluye que los pronósticos para la producción de cultivos agrícolas pueden variar de un método a otro, dependiendo además de la data y del tiempo, de un alto coeficiente de determinación del modelo de regresión, de un resultado en números reales positivos y del menor error porcentual de desviación absoluta

Relationship between olive oil consumption and ankle-brachial pressure index in a population at high cardiovascular risk

The aim of this study was to ascertain the association between the consumption of different categories of edible olive oils (virgin olive oils and olive oil) and olive pomace oil and ankle-brachial pressure index (ABI) in participants in the PREDIMED-Plus study, a trial of lifestyle modification for weight and cardiovascular event reduction in individuals with overweight/obesity harboring the metabolic syndrome. Methods: We performed a cross-sectional analysis of the PREDIMED-Plus trial. Consumption of any category of olive oil and olive pomace oil was assessed through a validated food-frequency questionnaire. Multivariable linear regression models were fitted to assess associations between olive oil consumption and ABI. Additionally, ABI ≤1 was considered as the outcome in logistic models with different categories of olive oil and olive pomace oil as exposure. Results: Among 4330 participants, the highest quintile of total olive oil consumption (sum of all categories of olive oil and olive pomace oil) was associated with higher mean values of ABI (beta coefficient: 0.014, 95% confidence interval [CI]: 0.002, 0.027) (p for trend = 0.010). Logistic models comparing the consumption of different categories of olive oils, olive pomace oil and ABI ≤1 values revealed an inverse association between virgin olive oils consumption and the likelihood of a low ABI (odds ratio [OR] 0.73, 95% CI [0.56, 0.97]), while consumption of olive pomace oil was positively associated with a low ABI (OR 1.22 95% CI [1.00, 1.48]). Conclusions: In a Mediterranean population at high cardiovascular risk, total olive oil consumption was associated with a higher mean ABI. These results suggest that olive oil consumption may be beneficial for peripheral artery disease prevention, but longitudinal studies are needed

Amazonia Camtrap: a data set of mammal, bird, and reptile species recorded with camera traps in the Amazon forest.

Abstract : The Amazon forest has the highest biodiversity on Earth. However, information on Amazonian vertebrate diversity is still deficient and scatteredacross the published, peer-reviewed, and gray literature and in unpublishedraw data. Camera traps are an effective non-invasive method of surveying vertebrates, applicable to different scales of time and space. In this study, we organized and standardized camera trap records from different Amazonregions to compile the most extensive data set of inventories of mammal,bird, and reptile species ever assembled for the area. The complete data setcomprises 154,123 records of 317 species (185 birds, 119 mammals, and13 reptiles) gathered from surveys from the Amazonian portion of eightcountries (Brazil, Bolivia, Colombia, Ecuador, French Guiana, Peru,Suriname, and Venezuela). The most frequently recorded species per taxawere: mammals:Cuniculus paca (11,907 records); birds: Pauxi tuberosa (3713 records); and reptiles:Tupinambis teguixin(716 records). The infor-mation detailed in this data paper opens up opportunities for new ecological studies at different spatial and temporal scales, allowing for a moreaccurate evaluation of the effects of habitat loss, fragmentation, climatechange, and other human-mediated defaunation processes in one of themost important and threatened tropical environments in the world. The data set is not copyright restricted; please cite this data paper when usingits data in publications and we also request that researchers and educator sinform us of how they are using these data

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection
