On thermo-mechanical issues induced by irradiation swelling inside the back-plate of the IFMIF target assembly
2011
Abstract Within the framework of the IFMIF R&D program and in close cooperation with ENEA-Brasimone, at the Department of Nuclear Engineering of the University of Palermo a research campaign has been launched to investigate the thermo-mechanical issues potentially induced by irradiation swelling in the threaded connections between frame and back-plate of IFMIF target assembly. The main aim of the research campaign has relied in the assessment of the maximum swelling-induced volumetric strain that may be accepted in order to allow screws to withstand thermo-mechanical stresses and work in safe conditions or to avoid unduly high unscrewing torques during back-plate remotely handled maintenanc…
Progressive hemifacial atrophy : Case report
2006
Progressive Hemifacial Atrophy, also known as Parry-Romberg Syndrome, is an uncommon degenerative and poorly understood condition. It is characterized by a slow and progressive atrophy affecting one side of the face. The incidence and the cause of this alteration is unknown. A cerebral disturbance of fat metabolism has been proposed as a primary cause. This can be the result of a trophic malformation of Cervical Sympathetic Nervous System. Possible factors that are involved in the pathogenesis include trauma, viral infections, heredity, endocrine disturbances and auto-immunity, among others. The most common complications that appear in association to this health disorder are: trigeminal neu…
Spēļošana pašvadītu mācīšanās prasmju attīstībai 5. Klases skolēniem angļu valodas stundās
2022
Diplomdarba mērķis ir izpētīt, kādi spēļošanas elementi var palīdzēt attīstīt skolēnu pašvadītas mācīšanās prasmes 5. klases angļu valodas stundās, jo pašvadītas mācīšanās prasmes ir nozīmīgas skolēnu turpmākajai dzīvei. Turklāt iepriekšējā pētījumā autore atklāja, ka spēļošana ir efektīvs līdzeklis, lai saglabātu skolēnu interesi un motivāciju. Kā pētījuma metode tika izvēlēta gadījuma izpēte. Datu vākšanas metodes ietvēra anketu, autores pašnovērtējumu un angļu valodas stundu refleksijas, kā arī skolēnu atsauksmes. Attiecīgi tika konstatēts, ka skolēniem varētu trūkt konkrētas prasmes, kas veido pašvadītu mācīšanos. Tā kā katra skolēna mācīšanās vajadzības un vēlmes var atšķirties, skolot…
A case study on gamified interventions for team cohesion in factory work
2018
In this article, we aim to provide insights into the design and implementation of game elements for teamwork on the work floor and to study their effect. Inventing games to break monotonous jobs is a long-standing practice, yet conscious implementation of motivational elements of games at work is a recent phenomenon. Generally, gamification is used to enhance individual performance; it may be effective in enhancing teamwork as well. We developed game elements aimed at team cohesion and examined the effect of two gamified interventions (team performance feedback and personal profiles) on team cohesion in a factory. Results suggest that the interventions mainly raised attention toward the asp…
Electrokinetic chromatographic estimation of the enantioselective binding of nomifensine to human serum albumin and total plasma proteins
2012
This report is the first evidence of enantioselective binding of nomifensine to human serum albumin (HSA) and plasma proteins. The overall process with HSA included: (i) consistent experimental design along two independent sessions; (ii) incubation of nomifensine–HSA designed mixtures; (iii) ultrafiltration for separating the unbound enantiomers fraction; (iv) electrokinetic chromatography (EKC) using heptakis-2,3,6-tri-O-methyl-β-cyclodextrin as chiral selector to provide experimental data for enantiomers (first, E1, and second, E2, eluted ones); and (v) a recent direct equation allowing univariate tests and robust statistics to provide consistent parameters and uncertainty. A significant …
The Structure and the Stereochemistry of Atractyliretin
1986
The nor-kaurane diterpene Atractyliretin was obtained by acid hydrolysis of Atractyloside, a toxic substance isolated from ATRACTYLIS GUMMIFERA L (Compositae). On the basis of spectral (IR, (1)H-NMR, (13)C-NMR and MS) analysis and chemical degradation its structure and stereochemistry was identified as 4.
Resultados de un programa de educación postural, con una intervención gamificada vs intervención tradicional
2021
[Resumen] La metodología de enseñanza adoptada por el profesorado puede influir en los niveles de participación y aprendizaje del alumnado. El objetivo principal de este estudio fue comparar el efecto de dos programas de intervención de educación postural en función de la metodología utilizada. Un total de 36 estudiantes (19 niñas y 17 niños) de 1º de Educación Secundaria Obligatoria participaron en el estudio. En el primer programa de intervención se aplicó una metodología gamificada, mientras que en el segundo se empleó una metodología tradicional. Ambos programas de intervención se llevaron a cabo a lo largo de 6 sesiones. Se analizaron los contenidos teóricos a través de dos cuestionari…
Cluster growth with long-range interactions
1996
Abstract Growth models in which the morphology depends on interactions of the type V(r) = C r n are presented. The growth algorithms are generalizations of DLA. The particles diffuse on a triangular lattice and eventually either stick to the cluster or are lost. Several processes are simulated in this way: in one case only pure sticking is taken into account, in another case evaporation and rearrangement are also allowed to occur. In the former case (with attractive interactions) the clusters exhibit a highly symmetric shape (a sixfold star) whose detailed structure depends on n , C kT , and time. In the latter case (studied with repulsive dipolar interactions) the tendency to ramification …
La gamificación como herramienta para reducir los accidentes laborales viales en pymes y autónomos
2018
El uso del vehículo constituye un medio de transporte imprescindible para muchos trabajadores, que lo utilizan para sus desplazamientos a sus lugares de trabajo o en el desarrollo de su actividad profesional. Actualmente en España el 13,45% de los accidentes laborales son de tráfico, siendo importante para su prevención invertir en formación e incorporar la cultura de la seguridad vial como parte de la actividad corriente de la organización. En este trabajo se propone el uso de la gamificación como herramienta para la formación y concienciación de los trabajadores autónomos y pymes en el esfuerzo por reducir el número de accidentes laborales viales en sus organizaciones. Para ello se descri…
Clusterin gene expression in apoptotic MDCK cells is dependent on the apoptosis-inducing stimulus
1995
Abstract Clusterin (Apolipoprotein J, complement lysis inhibitor) is a widely expressed multifunctional glycoprotein. The expression of clusterin mRNA has been reported to be elevated in a broad spectrum of apoptotic or degenerative tissues. More recently, it was shown that within these tissues clusterin is expressed in the surviving rather than in the dying cells, and that clusterin gene expression is actually down-regulated in the apoptotic cells. We have studied the expression of the clusterin gene in apoptotic MDCK cells. Cell death was initiated by three different stimuli: application of the steroid hormone antagonist RU 486, activation of protein kinase C by the application of the pho…
