Seroprevalencia de la toxoplasmosis humana en Córdoba

Se realiza un estudio sobre seroprevalencia de la toxoplasmosis humana en Córdoba, mediante inmunofluorescencia indirecta y hemaglutinación indirecta. La muestra encuestada se compone de 443 sueros, 356 personas supuestamente sanas (estudiantes fundamentalmente) y 87, consideradas de “alto riesgo” (enfermos del Hospital “Reina Sofía”). La positividad obtenida para el total de la muestra ha sido del 43,79 % con IFI y 53,50 % para HAI. Con respecto al sexo, la prevalencia es superior en mujeres con un 54,36 % y 70,47 % con IFI y HAI, respectivamente, en varones el 38,43 % y 44,90 % para las mismas pruebas. En relación con la procedencia de la muestra, 31,lB % con IFI y 43,25 % para HAI sobre la población normal, en la de “alto riesgo” para ambas pruebas el 95,40 %. Entre ambas pruebas hay diferencias significativas a títulos bajos, no así en diluciones altas, Concluimos que la toxoplasmosis humana está presente y difundida en las poblaciones estudiadasA seroprevalency study of human toxoplasmosis was carried out in Córdoba, using indirect immunofluorescence and indirect haemoglutination. The sample of people interviewed was made up of 443 serums, 356 supposedly healthy people (mainly students) and 87, considered “high risk” (pafients from the “Reina Sofia” Hospital). The positiveness obtained for the total of the sample was 43,79 % with IFI and 53,59 % for HAI. As regards sex of the person tested, prevalence is higher in women, with 54,36 % and 70,47 % with IFI and HAI respectively, in men the scores were 38,43 % and 44,90 % for the same tests. As far as the origin of the sample was concerned, there were 31,lB % with IFI and 43,25 % for HAI of the nornal population, in the “high risk” sample, for both tests it was 9540 %. With both tests there are significative differences in low amounts, but not in high dilutions. We conclude that human toxoplasmosis is present and widespread in the studied population

Using Large Language Models for Interpreting Autonomous Robots Behaviors

The deployment of autonomous robots in various domains has raised significant concerns about their trustworthiness and accountability. This study explores the potential of Large Language Models (LLMs) in analyzing ROS 2 logs generated by autonomous robots and proposes a framework for log analysis that categorizes log files into different aspects. The study evaluates the performance of three different language models in answering questions related to StartUp, Warning, and PDDL logs. The results suggest that GPT 4, a transformer-based model, outperforms other models, however, their verbosity is not enough to answer why or how questions for all kinds of actors involved in the interaction

Estudio cinegético de la digestión anaerobia de alpechín, procedente de la extracción de aceite utilizando olivex, previamente biotratado con Geotrichum Candidum

A kinetic study of the anaerobic digestion of olive mill wastewater (OMW) which was obtained with the technological helper "Olivex", was carried out. An identical wastewater, obtained without this enzyme was also used. Both OMW were pre-treated aerobically with Geotrichum Candidum to eliminate the greater part of the phenolic compounds responsible for inhibition. The anaerobic process was carried out in bioreactors with microorganisms immobilized on two micronized clay supports, Sepiolite and Bentonite. Assuming that the overall anaerobic digestion process conforms to a first-order kinetic, specific rate constants, Ko, were obtained by using the Roediger's equation in each case. In contrast to what takes place with both OMW without pretreatment, kinetic constant was observed virtually constant when the substrate concentration was increased, in the range of COD (chemical oxygen demand) studied. The mean value of this kinetic parameter was a 40% larger for the OMW obtained with Olivex compared to the reference OMW, in the two digesters used. Sepiolite favoured the kinetic and increased the yield coefficient compared to Bentonite.Se ha efectuado un estudio cinético del proceso de digestión anaerobia de un alpechín obtenido con el coadyuvante tecnológico "Olivex" en comparación con un testigo obtenido sin este enzima, que previamente han sido tratados de forma aerobia con Geotrichum Candidum para eliminar la mayor parte de los compuestos fenólicos responsables de su poder inhibidor. El proceso anaerobio se ha realizado en biorreactores con microorganismos inmovilizados en dos soportes micronizados arcillosos, Sepiolita y Bentonita. Admitiendo que globalmente el proceso de digestión anaerobia sigue una cinética de primer orden, se obtienen las constantes específicas de velocidad, Ko, para cada caso estudiado usando la ecuación de Roediger. A diferencia de lo que ocurre con ambos alpechines sin pretratar, la constante cinética se mantiene prácticamente constante al aumentar la concentración de sustrato, dentro del intervalo DQO (demanda química de oxígeno) estudiado, no apreciándose fenómenos de inhibición. El valor medio de este parámetro cinético para el alpechín obtenido con Olivex es más del 40% superior que el correspondiente al alpechín testigo en los dos digestores utilizados. El soporte Sepiolita favorece la cinética y aumenta el coeficiente de rendimiento respecto a la Bentonita
