Co-treatment of landfill leachate in laboratory-scale sequencing batch reactors: analysis of system performance and biomass activity by means of resp…
2014
Aged or mature leachate, produced by old landfills, can be very refractory; for this reason mature leachate is difficult to treat alone, but it can be co-treated with sewage or domestic wastewater. The aim of the study was to investigate the feasibility of leachate co-treatment with synthetic wastewater, in terms of process performance and biomass activity, by means of respirometric techniques. Two sequencing batch reactors (SBRs), named SBR1 and SBR2, were fed with synthetic wastewater and two different percentages of landfill leachate (respectively 10% and 50% v v−1 in SBR1 and SBR2). The results showed good chemical oxygen demand (COD) removal efficiency for both reactors, with average C…
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.

Mapping a-priori defined plant associations using remotely sensed vegetation characteristics
2014
Abstract Incorporation of a priori defined plant associations into remote sensing products is a major challenge that has only recently been confronted by the remote sensing community. We present an approach to map the spatial distribution of such associations by using plant indicator values (IVs) for salinity, moisture and nutrients as an intermediate between spectral reflectance and association occurrences. For a 12 km 2 study site in the Netherlands, the relations between observed IVs at local vegetation plots and visible and near-infrared (VNIR) and short-wave infrared (SWIR) airborne reflectance data were modelled using Gaussian Process Regression (GPR) (R 2 0.73, 0.64 and 0.76 for sali…
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…
Comparison of condensed versus noncondensed cycling test methods and correlation to a 185 minutes’ indoor race simulation
2017
Master's thesis Sports Science ME517 - University of Agder 2017 Background: The validity of a currently used condensed indoor test protocols (C-TP) as measurement of competitive cycling performance is questioned. Purpose: C-TP contain testing of wattage at lactate threshold (LTW), maximum oxygen consumption (VO2max) and a Wingate anaerobic test (WAnT), performed consecutively during one session. As comparison these tests were separated and performed individually over three consecutive days, giving a non-condensed test protocol (NC-TP). The results were compared to a 5min all-out cycling test (5min all-out) performed individually and as part of a 185 minutes’ race simulation. Method: During …
Effect of Land-Use Change on the Changes in Human Lyme Risk in the United States
2022
The spatial extent and incidence of Lyme disease is increasing in the United States, particularly in the Upper Midwest and Northeast. Many previous studies have explored the drivers of its spatial pattern, however, few studies tried to explore the drivers for the changes of Lyme disease. We here compared the spatial patterns of changes of human Lyme cases and incidence in the Northeast and Upper Midwest between 2003–2005 and 2015–2017, and applied two different approaches (i.e., a statistical regularization approach and model averaging) to investigate the climatic and landscape factors affecting the risk change between the two periods. Our results suggested that changes in land-use variable…
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…
Il Transformative Learning nei futuri insegnanti di sostegno: un’indagine in laboratorio
2022
Il presente lavoro illustra gli esiti di un’indagine condotta con 2193 corsisti frequentanti i laboratori del VI ciclo del corso di specializzazione per le attività di sostegno didattico dell’Università degli Studi di Palermo svoltosi nell’A.A. 2021/2022. La finalità dell’indagine è stata quella di rilevare il grado di consapevolezza dei taciti assunti e delle aspettative, nonché di quelle degli altri e valutarne la rilevanza a fini interpretativi, dei futuri docenti di sostegno, nel processo laboratoriale che li ha coinvolti per 180 ore. La cornice teorica all’interno della quale si delinea l’indagine è quella del Transformative Learning (Mezirow, 2013), che riteniamo fondamentale per la c…
