High-Sensitivity Whispering Gallery Mode Humidity Sensor Based on Glycerol Microdroplet Volumetric Expansion
2021
We demonstrate a highly sensitive whispering gallery mode (WGM) relative humidity (RH) sensor based on a glycerol microdroplet. WGMs were excited using a 760 nm tunable semiconductor laser. We used free space coupling, which is effective when using a liquid resonator. A detailed analysis of different parameters influencing the sensor’s characteristics (sensitivity, hysteresis, resolution, stability, and temperature) is presented. The sensitivity of the sensor is one of the highest reported (2.85 nm/% RH in the range 50–70% RH with the resolution 1 × 10−4% RH). This type of humidity sensor has several advantages, such as high sensitivity, extended lifetime, good repeatability, and low cost, …

Farming intensity indirectly reduces crop yield through negative effects on agrobiodiversity and key ecological functions
2022
International audience; Farming intensity and landscape heterogeneity influence agrobiodiversity and associated ecological functions. The relative contributions of these agroecosystem components to agricultural production remain unclear because of inter-relations and weather-dependant variations. Using a structural equation modelling approach, we estimated direct and indirect contributions of farming intensity (soil management, pesticide use and fertilisation) and landscape heterogeneity (of semi-natural covers and crop mosaic) to cereal crop production, in 54 fields (mostly wheat), in two years (24 and 30 fields). Indirect effects were evaluated through agrobiodiversity (carabid and plant …
Musculoskeletal disorders and disability among forest industry workers in lower and higher sickness absence groups: a case-control study
2019
Background: Musculoskeletal wellbeing and disorders and explanatory factors were investigated among forest industry employees. Methods: A new positive approach to maintenance of working ability focuses on being present at work. 140 individuals with low sickness absence (≤1.5% in hours during the past 6.5 years) and 140 controls with higher sickness absence (>1.5%), randomly selected from the source population (n = 636) in workplace clusters (n = 5), were studied. Questionnaire data on functioning, musculoskeletal disorders (MSD) and disability, work ability and wellbeing were collected (response rate 65%) during December 2012–January 2013. 183 employees (mean age 48.5; females 32%) particip…
Técnicas de Evaluación en educación primaria y secundaria
2022
La evaluación en el aula es una acción imprescindible en el sistema educativo y por ende en la enseñanza. El gran desafío que se plantea en nuestro sistema educativo es la evaluación del alumnado en el aula, cómo mejorar la evaluación del alumnado dentro del sistema educativo. Esta simple pero tan profunda cuestión, cómo mejorar la evaluación, implica un esfuerzo de toda la comunidad educativa. Realizar una investigación respecto a la evaluación implica enfrentarse a un gran titán, ya que el estudio de la evaluación es un gran reto de la sociedad actual. Al hablar del modo en que se realiza la evaluación en el aula, se involucra a multitud de agentes: profesorado, alumnado, familia, sistema…

Supportive Communication in the Workplace
2019
Supportive communication is a form of social interaction that produces resources with which to solve situational problems and manage emotional strain. Through the management of uncertainty, supportive communication enhances the perception of personal control over life events and strengthens the perception of acceptance. It is enacted in the seeking of support, in providing support, and in supportive listening as a form of emotional and informational support. In the workplace, supportive communication is crucially important: It promotes productive work and employees’ well-being as well as job satisfaction and engagement in the organization. This chapter presents the foundations of supportive…
W kwestii pominięcia przez sąd administracyjny niekonstytucyjnych przepisów ustawy
2021
W publikacji przedstawiono podstawy orzekania przez sąd administracyjny z pominięciem przepisu ustawy, który ten sąd ocenia jako niekonstytucyjny. Tym samym podejmuje problematykę realizacji podstawowego celu, jakim jest ukazanie roli sądownictwa administracyjnego w ostatecznym ukształtowaniu praw i obowiązków adresata działań administracji jako gwaranta ochrony praw jednostki, która mogłaby zostać pozbawiona ochrony prawnej na etapie stosowania prawa przez podmiot dysponujący władztwem administracyjnym (imperium). Rolę tę zaprezentowano w aspekcie orzekania przez sądy administracyjne w sytuacji, gdy TK uznał normy zawarte w przepisie poddanego jego kontroli aktu za niekonstytucyjne, a któr…
Maxillary necrosis by mucormycosis : a case report and literature review
2007
The maxilla rarely undergoes necrosis due to its rich vascularity. Maxillary necrosis can occur due to bacterial infections such as osteomyelitis, viral infections such as herpes zoster or fungal infections such as mucormycosis, aspergillosis etc. Mucormycosis is an opportunistic fulminant fungal infection, which mainly infects immunocompromised patients. The infection begins in the nose and paranasal sinuses due to inhalation of fungal spores. The infection can spread to orbital and intracranial structures either by direct invasion or through the blood vessels. The fungus invades the arteries leading to thrombosis that subsequently causes necrosis of hard and soft tissues. We report a case…
Resuscitative endovascular balloon occlusion of the aorta (REBOA) in patients with major trauma and uncontrolled haemorrhagic shock: a systematic rev…
2021
AbstractBackgroundMultiple studies regarding the use of Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) in patients with non-compressible torso injuries and uncontrolled haemorrhagic shock were recently published. To date, the clinical evidence of the efficacy of REBOA is still debated. We aimed to conduct a systematic review assessing the clinical efficacy and safety of REBOA in patients with major trauma and uncontrolled haemorrhagic shock.MethodsWe systematically searched MEDLINE (PubMed), EMBASE and CENTRAL up to June 2020. All randomized controlled trials and observational studies that investigated the use of REBOA compared to resuscitative thoracotomy (RT) with/witho…
