ESSAI RANDOMISÉ POUR ÉVALUER L’EFFICACITÉ ET LA SÉCURITÉ DE TRAITEMENTS CHEZ DES PATIENTS AMBULATOIRES ATTEINTS DE COVID-19 AYANT DES FACTEURS DE RIS…
2021
Context. The Covid-19 pandemic is of unprecedented magnitude and has had major social and health consequences. Primary care professionals, mainly general practitioners, ensure the care of most patients with Covid-19. An early-stage treatment administered to patients with risk factors for developing a severe disease could reduce hospitalization and death rates. No treatment is currently validated in this indication. Objectives. To evaluate the safety and efficacy of experimental candidate agents delivered in outpatient settings to reduce the risk of hospitalization or death in at-risk patients with early-stage proven Covid-19 and no indication for hospital admission. Methods. Multicentric, o…
Stationary, Second Use Battery Energy Storage Systems and Their Applications: A Research Review
2021
The global demand for electricity is rising due to the increased electrification of multiple sectors of economic activity and an increased focus on sustainable consumption. Simultaneously, the share of cleaner electricity generated by transient, renewable sources such as wind and solar energy is increasing. This has made additional buffer capacities for electrical grids necessary. Battery energy storage systems have been investigated as storage solutions due to their responsiveness, efficiency, and scalability. Storage systems based on the second use of discarded electric vehicle batteries have been identified as cost-efficient and sustainable alternatives to first use battery storage syste…
Diversidad genética de los principales vectores de la enfermedad de Chagas en Brasil: repercusiones epidemiológicas en el control de la enfermedad
2017
La enfermedad de Chagas, también llamada Tripanosomiasis Americana, es una enfermedad potencialmente mortal causada por el parásito protozoo Trypanosoma cruzi, es endémica de América Latina y transmitida, principalmente, por vectores hemípteros de la subfamilia Triatominae adaptados a los hábitats doméstico y peridoméstico. Puesto que el parásito se mantiene en un ciclo zoonótico silvestre y es imposible de eliminar, la única forma de luchar contra la transmisión vectorial consiste en la eliminación de las poblaciones domiciliadas del vector. Los estudios moleculares constituyen una herramienta de gran utilidad a la hora de planificar las campañas de control vectorial, puesto que permiten c…
Epidemiología y Control de la Enfermedad de Chagas en el Departamento de Cochabamba (Bolivia).
2015
La enfermedad de Chagas es uno de los problemas más graves de salud pública que afectan a América Latina; históricamente extensas áreas de Bolivia han registrado la mayor prevalencia de la infección por su agente causal, el protozoo Trypanosoma cruzi. A principios del año 2000, en este país se puso en marcha un programa de control vectorial, que consistió en el rociado masivo de viviendas con insecticidas piretroides, instaurado para controlar la infestación de viviendas por los insectos hematófagos que transmiten la enfermedad. En este trabajo se proporciona una evaluación detallada de los efectos de este programa en el Departamento de Cochabamba, uno de los lugares más endémico de todo el…
Parametric sensitivity of a CFD model concerning the hydrodynamics of trickle-bed reactor (TBR)
2016
Abstract The aim of the present study was to investigate the sensitivity of a multiphase Eulerian CFD model with respect to relations defining drag forces between phases. The mean relative error as well as standard deviation of experimental and computed values of pressure gradient and average liquid holdup were used as validation criteria of the model. Comparative basis for simulations was our own data-base obtained in experiments carried out in a TBR operating at a co-current downward gas and liquid flow. Estimated errors showed that the classical equations of Attou et al. (1999) defining the friction factors Fjk approximate experimental values of hydrodynamic parameters with the best agre…
Atomic layer deposition of localised boron- and hydrogen-doped aluminium oxide using trimethyl borate as a dopant precursor
2020
Atomic layer deposition (ALD) of boron-containing films has been mainly studied for use in 2D materials and for B-doping of Si. Furthermore, lithium-containing borates show great promise as solid electrolyte coatings for enhanced energy storage. In this work, we examine trimethyl borate (TMB) and triethyl borate (TEB) in combination with O2 plasma as precursors for ALD of B-containing films, targeting the growth of B2O3. It is found that films grown from TEB contain no boron. Further work with TMB as a boron-containing precursor showed promising initial growth on a SiO2 or Al2O3 surface, but a rapid decrease of the growth rate during subsequent ALD cycles indicating surface inhibition durin…
Trollaaminen ja sen vaikutukset Facebookissa
2017
Trollaaminen on aktiviteetti, mitä tapahtuu sosiaalisessa mediassa ja se yhidstetään pääosin haitalliseen toimintaan. Suurinosa trollauksesta tapahtuu anonymiteetin turvin, mutta joskus trolli saattaa toimia myös omalla identiteetillään. Trollauksen vaikutukset uhriin voivat vaihdella lievistä ärsytyksen tunteista paljon vakavampiin vaikutuksiin, kuten itsensä vahingoittamiseen tai itsemurhaan. Kun trollausta tapahtui enimmäkseen chat-huoneissa, missä lukijakunta oli rajoittunut, trollausta ei otettu vakavasti. Sosiaalisen median yleistyessä trollaus levisi myös, jolloin se mahdollisti trollauksen näkyvyyden suuremmalle lukijakunnalle. Nykyään trollaamiseen suhtaudutaan vakavammin ja jopa K…
Situational factors shape moral judgements in the trolley dilemma in Eastern, Southern and Western countries in a culturally diverse sample
2022
The study of moral judgements often centres on moral dilemmas in which options consistent with deontological perspectives (that is, emphasizing rules, individual rights and duties) are in conflict with options consistent with utilitarian judgements (that is, following the greater good based on consequences). Greene et al. (2009) showed that psychological and situational factors (for example, the intent of the agent or the presence of physical contact between the agent and the victim) can play an important role in moral dilemma judgements (for example, the trolley problem). Our knowledge is limited concerning both the universality of these effects outside the United States and the impact of …
Strategie językowe trolli internetowych
2018
The anonymity of Internet users very often leads to the violation o f netiquette rules. One of the groups of Internet users who violate the commonly accepted ways of communicating on the Internet are trolls posting provocative commentaries to start conflict. The most frequent result of their attempts is fiame, which is a serious Internet argument loaded with spite. Among linguistic strategies used by trolls are the following: posting commentaries with a lot of intentionally misspelled words, generalizability, use of negative stereotypes, off-topic commentaries (that is starting threads unrelated to the topie of the article or post), emphasizing their own high materiał status, and disparagem…
Tracking mite trophic interactions by multiplex PCR
2020
Background A thorough knowledge of trophic webs in agroecosystems is essential to achieve successful biological pest control. Phytoseiid mites are the most efficient natural enemies of tetranychid mites, which include several important pests worldwide. Nevertheless, phytoseiids may feed on other food sources including other microarthropods, plants and even other phytoseiids (intraguild predation), which can interfere with biological control services. Molecular gut content analysis is a valuable tool for characterizing trophic interactions, mainly when working on microarthropods such as mites. We have designed new primers for Phytoseiidae, Tetranychidae and Thysanoptera identification and th…
