Alternative Calibration of Cup Anemometers: A Way to Reduce the Uncertainty of Wind Power Density Estimation

T1 Q1 (15/64 Instruments & Instrumentation, IF 2019= 3.275)This study presents a procedure to reduce the uncertainty of wind power density estimations, which is useful to improve the energy production predictions of wind farms. Power density is usually determined from the wind speed measured by a cup anemometer and the air density value (conventional procedure). An alternative procedure based on wind speed and dynamic pressure estimations provided by a cup anemometer is proposed. The dynamic pressure is obtained by means of a calibration curve that relates the anemometer rotation frequency and the dynamic pressure measured by a Pitot tube. The quadratic regression, used to define the calibration curve, and its uncertainty are both detailed. A comparison between the alternative procedure and the conventional one points out the advantage of the proposed alternative since results show a high reduction of the indirect measurement uncertainty of wind power density

Aerobiological and allergenic analysis of Cupressaceae pollen in Granada (Southern Spain)

Cupressaceae pollen has been cited in recent years as one of the major airborne allergens of the Mediterranean region, prompting us to conduct an exhaustive analysis on the aerobiological behaviour of this pollen in the Iberian Peninsula and the repercussion that it has had on the atopic population. The aerobiological study, performed from 1996 to 2003 in the city of Granada (S. Spain), used a volumetric Hirst collector. The results indicate that this pollen is present in the air most of the year, registering a high incidence during the winter months. This type of pollen behaved irregularly in the air, fluctuating yearly, seasonally, and within the same day. Temperature and humidity were the parameters that most directly influence the variability of this allergen, while rainfall prior to flowering increased pollen production. The predictive models used estimated a high percentage of the levels reached over the short term by this pollen in the atmosphere of Granada. The clinical study performed with atopic patients showed that some 30% of the population with pollinosis are sensitive to Cupressaceae pollen, affecting people of both genders equally. On the other hand, the most sensitive age group was 21-40 years of age, while children and the elderly registered almost negligible values. Most of the sensitive subjects resided within the city or in the metropolitan area, where environmental pollution reached high levels, while the pathology was found to be less frequent in rural zones. The most frequent symptoms were upper-respiratory ailments and an asthmatic profile.En los últimos años el polen de Cupressaceae se ha considerado uno de los principales alérgenos aéreos de la región Mediterránea, lo que motivó la realización de un análisis exhaustivo del comportamiento aerobiológico de este polen en la Península Ibérica y de la repercusión que tenía en la población atópica. En el estudio aerobiológico, llevado a cabo entre 1996 y 2003 en la ciudad de Granada (sur de España), se utilizó un captador volumétrico tipo Hirst. Los resultados indican que este polen se encuentra presente en el aire la mayor parte del año, pero registra una alta incidencia en los meses de invierno. Este tipo de polen mostró un comportamiento irregular en el aire, con fluctuaciones anuales, estacionales y en un mismo día. La temperatura y la humedad fueron los parámetros que influyeron más directamente en la variabilidad de este alérgeno, mientras que la lluvia antes de la floración incrementó la producción de polen. Los modelos predictivos utilizados estimaron un porcentaje elevado de los niveles alcanzados a corto plazo por este polen en la atmósfera de Granada. El estudio clínico realizado con pacientes atópicos mostró que un 30% de la población con polinosis es sensible al polen de Cupressaceae, afectando a ambos sexos por igual. Por otra parte, el grupo de edad más sensible fue el de 21 a 40 años, mientras que los niños y los ancianos registraron valores casi insignificantes. La mayoría de los sujetos sensibles residían en el núcleo urbano o en el área metropolitana, donde la contaminación ambiental alcanza niveles elevados, mientras que la patología fue menos frecuente en la zona rural. Los síntomas más frecuentes fueron afecciones de las vías respiratorias altas y un perfil asmático.The authors wish to thank the Spanish Ministry of Science and Technology for financing this study with the “Análisis de la actividad alergénica de la atmósfera” project (BOS2002-03474)

Decreased levels of Thioredoxin o1 influences stomatal development and aperture but not Photosynthesis under non-stress and saline conditions

Salinity has a negative impact on plant growth, with photosynthesis being downregulated partially due to osmotic effect and enhanced cellular oxidation. Redox signaling contributes to the plant response playing thioredoxins (TRXs) a central role. In this work we explore the potential contribution of Arabidopsis TRXo1 to the photosynthetic response under salinity analyzing Arabidopsis wild-type (WT) and two Attrxo1 mutant lines in their growth under short photoperiod and higher light intensity than previous reported works. Stomatal development and apertures and the antioxidant, hormonal and metabolic acclimation are also analyzed. In control conditions mutant plants displayed less and larger developed stomata and higher pore size which could underlie their higher stomatal conductance, without being affected in other photosynthetic parameters. Under salinity, all genotypes displayed a general decrease in photosynthesis and the oxidative status in the Attrxo1 mutant lines was altered, with higher levels of H2O2 and NO but also higher ascorbate/glutathione (ASC/GSH) redox states than WT plants. Finally, sugar changes and increases in abscisic acid (ABA) and NO may be involved in the observed higher stomatal response of the TRXo1-altered plants. Therefore, the lack of AtTRXo1 affected stomata development and opening and the mutants modulate their antioxidant, metabolic and hormonal responses to optimize their adaptation to salinity.info:eu-repo/semantics/publishedVersio

Rich oleocanthal and oleacein extra virgin olive oil and inflammatory and antioxidant status in people with obesity and prediabetes. The APRIL study: A randomised, controlled crossover study

Background: Oleocanthal and oleacein are olive oil phenolic compounds with well known anti inflammatory and anti-oxidant properties. The main evidence, however, is provided by experimental studies. Few human studies have examined the health benefits of olive oils rich in these biophenols. Our aim was to assess the health properties of rich oleocanthal and oleacein extra virgin olive oil (EVOO), compared to those of common olive oil (OO), in people with prediabetes and obesity. Methods: Randomised, double-blind, crossover trial done in people aged 40e65 years with obesity (BMI 30e40 kg/m2 ) and prediabetes (HbA1c 5.7e6.4%). The intervention consisted in substituting for 1 month the oil used for food, both raw and cooked, by EVOO or OO. No changes in diet or physical activity were recommended. The primary outcome was the inflammatory status. Secondary outcomes were the oxidative status, body weight, glucose handling and lipid profile. An ANCOVA model adjusted for age, sex and treatment administration sequence was used for the statistical analysis. Results: A total of 91 patients were enrolled (33 men and 58 women) and finished the trial. A decrease in interferon-g was observed after EVOO treatment, reaching inter-treatment differences (P ¼ 0.041). Total antioxidant status increased and lipid and organic peroxides decreased after EVOO treatment, the changes reaching significance compared to OO treatment (P < 0.05). Decreases in weight, BMI and blood glucose (p < 0.05) were found after treatment with EVOO and not with OO. Conclusions: Treatment with EVOO rich in oleocanthal and oleacein differentially improved oxidative and inflammatory status in people with obesity and prediabetes.Funding for open access charge: Universidad de Málaga/CBU

Promoting Biodiversity and Contact with Nature in Education Degrees

[Resumen] En la sociedad actual existe una desconexión creciente con la naturaleza, lo que puede repercutir de forma negativa en el estado físico y mental, mostrando numerosos estudios los beneficios de estar en contacto con aquella. Es necesario, por lo tanto, la renaturalización de los centros educativos, incluidas las universidades. Las facultades de educación tienen, además, la oportunidad de servir de ejemplo para su numeroso estudiantado, de forma que puedan llevar las actuaciones y actividades realizadas durante el grado a los centros escolares. Este proyecto muestra la renaturalización de la Facultad de Ciencias de la Educación y Psicología de la Universidad de Córdoba (España), en la que se han reverdecido los espacios exteriores, se han adaptado para la docencia, se ha fomentado la biodiversidad y se ha facilitado la formación del estudiantado sobre la importancia de trabajar el contacto con la naturaleza como puntos clave para avanzar hacia la sostenibilidad.[Abstract] People today are becoming increasingly disconnected from nature, and suffering physically and mentally as a result. One solution to this is to undertake the renaturation of human environments, including schools and universities. Faculties of education have an opportunity to serve as an example to their students in this regard, by establishing models of reconnection for new teachers to take into schools subsequently. This project reports on the renaturation of the Faculty of Educational Sciences and Psychology at the University of Cordoba (Spain), where outdoor spaces have been greened and adapted for teaching, biodiversity has been promoted, and students have been trained in the importance of working in contact with nature in order to promote sustainability

Do specific antimicrobial stewardship interventions have an impact on carbapenem resistance in Gram-negative bacilli? A multicentre quasi-experimental ecological study: time-trend analysis and characterization of carbapenemases

CarbaPIRASOA team.[Background] Carbapenem-resistant Gram-negative bacilli (CR-GNB) are among the most threatening microorganisms worldwide and carbapenem use facilitates their spread. Antimicrobial stewardship programmes (ASPs) can help to optimize the use of antibiotics. This study evaluates the impact of a multifaceted educational ASP on carbapenem use and on the epidemiology of CR-GNB.[Methods] We conducted a quasi-experimental, time-series study in seven hospitals, from January 2014 to September 2018. The key intervention was composed of educational interviews promoting the appropriate use of carbapenems. The primary endpoints were carbapenem consumption and incidence density (ID) of CR-GNB. All non-duplicated CR-GNB clinical isolates were tested using phenotypic assays and PCR for the presence of carbapenemases. Joinpoint regression and interrupted time-series analyses were used to determine trends.[Results] A decrease in carbapenem consumption throughout the study period [average quarterly percentage change (AQPC) −1.5%, P < 0.001] and a −8.170 (−16.064 to −0.277) level change following the intervention were observed. The ID of CR-Acinetobacter baumannii decreased (AQPC −3.5%, P = 0.02) and the overall ID of CR-GNB remained stable (AQPC −0.4%, P = 0.52). CR-GNB, CR-Pseudomonas aeruginosa and CR-A. baumannii IDs per hospital correlated with the local consumption of carbapenems. The most prevalent carbapenem resistance mechanisms were OXA-23 for CR-A. baumannii (76.1%), OXA-48 for CR-Klebsiella pneumoniae (66%) and no carbapenemases for CR-P. aeruginosa (91.7%). The epidemiology of carbapenemases was heterogeneous throughout the study, especially for carbapenemase-producing Enterobacteriaceae.[Conclusions] In conclusion, a multifaceted, educational interview-based ASP targeting carbapenem prescribing reduced carbapenem use and the ID of CR-A. baumannii.This work was funded by the Spanish Infectious Diseases and Clinical Microbiology Society (SEIMC).Peer reviewe
