Computational modeling of molecularly imprinted polymers as a green approach to the development of novel analytical sorbents
2018
Abstract The development of novel molecularly imprinted polymers (MIP) sorbents for specific chemical compounds require a lot of tedious and time-consuming laboratory work. Significant quantities of solvents and reagents are consumed in the course of the verification of appropriate configurations of polymerization reagents. Implementation of molecular modeling in the MIP sorbent development process appears to provide a solution to this problem. Appropriate simulations and computations facilitate the determination of the nature of interaction between the reagents and thus the selection of the best configuration of chemicals for the preparation of the sorbent. The article presents literature …
Implementació i avaluació de codis QR en laboratoris docents d’enginyeria química
2014
Els codis QR (Quick Response) són codis de barra àmpliament utilitzats en aplicacions comercials i de màrqueting per incloure enllaços a pàgines web, entre altres coses. En l'actualitat un gran nombre de dispositius electrònics com telèfons intel·ligents o tauletes compten amb aplicacions capaces de capturar aquesta informació, permetent al seu usuari emmagatzemar-la i compartir-la amb altres usuaris. Hi ha alguns exemples de la seva aplicació en l'educació, encara que no s'han trobat exemples en l'àrea d'Enginyeria Química. En aquest context, el treball que es presenta és la implantació i avaluació de codis QR en laboratoris docents d'Enginyeria Química amb accés a contingut docent multimè…
Flow characteristics of a channelized debris-flow and implications in numerical modelling: a study case
2012
As it is known, debris flows are characterized by extreme propagation rapidity and by the ability to move high quantity of fluid mass. Furthermore, debris flows are fluid enough to travel long distances and, thus, to cause damage in vast areas, even far from the trigger ones. Debris-flow runout estimations are important for the delineation of potentially hazardous areas. Especially in recent years, several researches have been conducted in order to define predicitive models. But, existing runout estimation methods need input parameters that can be difficult to estimate. Recent advances in theory and in experimental research have allowed the assessment of the physics of the debris flows. On …
Dreams and Trauma Changes in the Manifest Dreams in Psychoanalytic Treatments - A Psychoanalytic Outcome Measure.
2021
Although psychoanalysts are interested in symptom reduction as an outcome, they are looking for instruments to measure sustaining changes in the unconscious mental functioning. In this article it is discussed that conceptually well-founded transformation of manifest dreams analyzed with precise empirical methods could be considered as a promising indicator for such therapeutic changes. We are summarizing a dream generation model by Moser and von Zeppelin which has integrated a large interdisciplinary knowledge base of contemporary dream and sleep research. Based on this model the authors have developed a valid and reliable coding system for analyzing manifest dreams, the Zurich Dream Proces…
Leishmania tarentolae and Leishmania infantum in humans, dogs and cats in the Pelagie archipelago, southern Italy.
2021
Visceral leishmaniasis (VL) caused by Leishmania infantum is endemic in the Mediterranean basin with most of the infected human patients remaining asymptomatic. Recently, the saurian-associated Leishmania tarentolae was detected in human blood donors and in sheltered dogs. The circulation of L. infantum and L. tarentolae was investigated in humans, dogs and cats living in the Pelagie islands (Sicily, Italy) by multiple serological and molecular testing. Human serum samples (n = 346) were tested to assess the exposure to L. infantum by immunofluorescence antibody test (IFAT), enzyme-linked immunosorbent assay (ELISA) and Western blot (WB) and to L. tarentolae by IFAT. Meanwhile, sera from do…
Rozwijanie kompetencji studentów prawa w obszarze nauk penalnych przy zastosowaniu nowych metod nauczania
2016
Stosowanie nowych metod nauczania jest niezmiernie istotne w kontekście rozwijania kompetencji studentów prawa, zwłaszcza w obszarze nauk penalnych. Autonomia programowa uczelni wyższych oraz normy ustawowe sprawiają, że możliwości wpływania na jakość kształcenia istnieją, abstrahując od sposobów finansowania nauki w Polsce. Zwiększanie umiejętności przyszłych prawników uwidocznione jest w naukach sądowych i kryminalistyce, a zaznajomienie ich z dorobkiem nauk przyrodniczych i technicznych, również w salach laboratoryjnych, może korzystnie wpływać na kompetencje zawodowe w przyszłości.

Trigeminal innervation of the mammalian pineal gland.
1999
There is evidence that the trigeminal (Gasserian) ganglia innervate the mamma- lian pineal gland and serve in its regulation in addition to the sympathetic and cholinergic as well as further influences. By means of immunohistochemical methods, previous studies demonstrated fibers containing calcitonin gene-related peptide (CGRP-LI) or substance P (SP) in the superficial pineal of various mammalian species. In addition, SP and the related tachykinin, neurokinin A, were detected by radioimmunoassay and HPLC, respectively, in the rat and human pineal gland. In the present study, retrograde neuronal tracing upon injection of a tracer substance into the superfical pineal gland of rats was used i…
Transcriptional Rewiring, Adaptation, and the Role of Gene Duplication in the Metabolism of Ethanol of Saccharomyces cerevisiae
2020
Ethanol is the main by-product of yeast sugar fermentation that affects microbial growth parameters, being considered a dual molecule, a nutrient and a stressor. Previous works demonstrated that the budding yeast arose after an ancient hybridization process resulted in a tier of duplicated genes within its genome, many of them with implications in this ethanol “produce-accumulate-consume” strategy. The evolutionary link between ethanol production, consumption, and tolerance versus ploidy and stability of the hybrids is an ongoing debatable issue. The implication of ancestral duplicates in this metabolic rewiring, and how these duplicates differ transcriptionally, remains unsolved. Here, we …
La riflessione sulla pratica didattica in laboratorio dei tutor di Scienze della Formazione Primaria - Reflection on tutors’ teaching practices in Pr…
2016
Il contributo presenta un’indagine esplorativa che ha come oggetto l’organizzazione dei laboratori di Scienze della Formazione Primaria dell’Università di Palermo; in particolare ci si è prefissi di osservare nei tutor coordinatori e organizzatori di tirocinio, che li conducono insieme ai docenti, le capacità di riflessione del proprio agire nell’ambito delle specifiche attività laboratoriali. L’intento è stato quello di avviare una riflessione su ciò che è realmente necessario per condurre un laboratorio e sulle competenze che l’insegnante deve possedere, per essere efficace nel suo agire professionale. Si è scelto di utilizzare il laboratorio universitario in quanto spazio pedagogico in c…
