Optimisation of photoluminescent painting treatments on different surface layers
2016
Improving drivers visibility in night time conditions is vital. Night-time visibility represents one of the most important features of road safety. Within such context, the use of photoluminescent road markings could represent an enhancement with regard to road safety. Consequently, the objective of the investigation here described was confined into the analysis of photoluminescent paints by referring to dense-graded and open-graded friction courses. Measurements, based on photometry technique, were carried out in the laboratory. Cores extracted from the surface layer of known pavements were used. Transitory effects (charge and discharge) and decay phenomena were investigated and modelled a…
Measuring nuclear reaction cross sections to extract information on neutrinoless double beta decay
2017
Neutrinoless double beta decay (0v\b{eta}\b{eta}) is considered the best potential resource to access the absolute neutrino mass scale. Moreover, if observed, it will signal that neutrinos are their own anti-particles (Majorana particles). Presently, this physics case is one of the most important research "beyond Standard Model" and might guide the way towards a Grand Unified Theory of fundamental interactions. Since the 0v\b{eta}\b{eta} decay process involves nuclei, its analysis necessarily implies nuclear structure issues. In the NURE project, supported by a Starting Grant of the European Research Council (ERC), nuclear reactions of double charge-exchange (DCE) are used as a tool to extr…
Teachers’ Focus of Attention in First-grade Classrooms: Exploring Teachers Experiencing Less and More Stress Using Mobile Eye-tracking
2021
This study investigated teachers’ focus of attention and stress in first-grade classrooms. Teachers’ (n = 53) focus of attention was recorded in fall and spring with a mobile eye-tracking device, and the teachers reported stress via questionnaires. Correlation analysis was used to examine association between teacher stress (exhaustion, cynicism, and inadequacy) and focus of attention. Then, one teacher reporting more stress and one reporting less stress were selected for a case study to examine variations in their focus of attention. The results showed positive associations between teachers’ perceived inadequacy and overall focus of attention (whole eye-tracking recording) both in fall and …
The serum copper/zinc ratio in childhood and educational attainment : a population-based study
2016
Background Micronutrients are potentially important determinants of adult outcomes such as educational attainment. Copper and zinc have known effects on several medical conditions and cognitive development. Elevated copper and depressed zinc is a common trace metal imbalance. Methods We estimate the correlation between the copper/zinc ratio (Cu/Zn) in childhood (year 1980) and educational attainment in adulthood (year 2010). We use the Young Finns Study (YFS) combined with the Finnish Linked Employer-Employee Data (FLEED). The regression models account for confounders such as other biomarkers and parental observables. Results We report a sizeable, negative correlation between Cu/Zn and educ…
Effects of emotions, grade level and gender on pseudoscience beliefs of secondary school students
2022
La educación secundaria desempeña un importante papel en la alfabetización científica y, en ella, las creencias en pseudociencias tienen una gran relevancia. Por esta razón, los objetivos de este estudio se centraron en la evaluación del nivel de adhesión a las creencias en pseudociencias de los estudiantes de secundaria y en el análisis de la influencia del género, nivel académico y emociones generadas en el aula de ciencias sobre dichas creencias. Participaron 125 estudiantes de tres cursos diferentes de educación secundaria (3º y 4º de ESO, y 1º de Bachillerato, esto es, 9º, 10º y 11º grado). A todos ellos se les administraron dos cuestionarios, uno para evaluar las creencias pseudocient…
End-of-Life Care in High-Grade Glioma Patients. The Palliative and Supportive Perspective.
2018
High-grade gliomas (HGGs) are the most frequently diagnosed primary brain tumors. Even though it has been demonstrated that combined surgical therapy, chemotherapy, and radiotherapy improve survival, HGGs still harbor a very poor prognosis and limited overall survival. Differently from other types of primary neoplasm, HGG manifests also as a neurological disease. According to this, palliative care of HGG patients represents a peculiar challenge for healthcare providers and caregivers since it has to be directed to both general and neurological cancer symptoms. In this way, the end-of-life (EOL) phase of HGG patients appears to be like a journey through medical issues, progressive neurologic…
Interplay Between MicroRNAs and Oxidative Stress in Ovarian Conditions with a Focus on Ovarian Cancer and Endometriosis
2019
Ovarian cancer and endometriosis are two distinct gynaecological conditions that share many biological aspects incuding proliferation, invasion of surrounding tissue, inflammation, inhibition of apoptosis, deregulation of angiogenesis and the ability to spread at a distance. miRNAs are small non-coding RNAs (19–22 nt) that act as post-transcriptional modulators of gene expression and are involved in several of the aforementioned processes. In addition, a growing body of evidence supports the contribution of oxidative stress (OS) to these gynaecological diseases: increased peritoneal OS due to the decomposition of retrograde menstruation blood facilitates both endometriotic lesion developmen…
Impact of biliary stents on the diagnostic accuracy of EUS-guided fine-needle biopsy of solid pancreatic head lesions: A multicenter study
2021
Background and Objectives: There is no clear evidence of a negative impact of biliary stents on the diagnostic yield of EUS-guided fine-needle biopsy (EUS-FNB) for diagnosing pancreatic head lesions. We aimed to evaluate the association between the presence of biliary stents and the diagnostic accuracy of EUS-FNB. Materials and Methods: A multicenter retrospective study including all jaundiced patients secondary to pancreatic head masses was performed. Patients were divided into two groups according to the presence of a biliary stent placed before EUS-FNB. Pathological results were classified according to the Papanicolaou classification and compared against the final diagnosis. Diagnostic m…
The Large Hadron–Electron Collider at the HL-LHC
2021
The Large Hadron-Electron Collider (LHeC) is designed to move the field of deep inelastic scattering (DIS) to the energy and intensity frontier of particle physics. Exploiting energy-recovery technology, it collides a novel, intense electron beam with a proton or ion beam from the High-Luminosity Large Hadron Collider (HL-LHC). The accelerator and interaction region are designed for concurrent electron-proton and proton-proton operations. This report represents an update to the LHeC's conceptual design report (CDR), published in 2012. It comprises new results on the parton structure of the proton and heavier nuclei, QCD dynamics, and electroweak and top-quark physics. It is shown how the LH…
"Tää oli kiva tunti!" : a social and emotional learning intervention in an EFL classroom
2018
Tunne- ja vuorovaikutustaidot vaikuttavat merkittävästi koulumenestykseen ja yleiseen hyvinvointiin. Myönteiset tunteet parantavat muun muassa motivaatiota, keskittymiskykyä, muistia, sujuvuutta ja oppimista. Tunne- ja vuorovaikutustaidot ovat keskeisiä kieltenoppimisessa ja –opettamisessa sillä nimenomaan kielen avulla kommunikoidaan ja ollaan vuorovaikutuksessa muiden ihmisten kanssa. Tämän tutkimuksen tavoitteena oli kehittää viidesluokkalaisten tunne- ja vuorovaikutustaitoja englanninopetuksen yhteydessä. Tutkija-opettaja järjesti opetuskokeilun keski-suomalaisessa alakoulussa, jossa tutkija toimi myös sijaisena. Tutkimuksen tavoitteena oli tutkia ja soveltaa tehtäviä joiden avulla void…
