Datu apstrādes prasmju pilnveide fizikas laboratorijas darbos vidusskolā
2017
Datu apstrādes prasmju pilnveide fizikas laboratorijas darbos vidusskolā. Dmitrijs Solovjovs, bakalaura darba vadītājs Dr.phys.Inese Dudareva. Bakalaura darbs – 90 lappuses, 36 literatūras avoti, 10 pielikumi, 5 tabulas, 36 attēli. Latviešu valodā. Darbā dots starppriekšmetu saiknes fizika-informātika raksturojums un apskatītas datorizētas datu apstrādes iespējas laboratorijas darbos fizikā. Izstrādāts un aprobēts darbu komplekts vidusskolai, kurš publicēts internetā. Konstatēts, ka datu apstrādes prasmes skolēniem pilnveidojušās. Anketēšanas rezultāti liecina, ka skolēniem vidusskolā neatkarīgi no klases ir pozitīva attieksme pret informātiku un tajā apgūto prasmju pielietojumu fizikā, dat…
Laboratorio di matematica in classe: due nuove macchine per problemi nel continuo e nel discreto
2013
In this work we will introduce two mathematical machines (originally invented by the authors) that can be useful in class during laboratorial activities. We decided to introduce them together because they appeared us complementary about the subtended contents, in fact one of them solves a discrete problem (diophantine equations) involving concepts as integers, divisibility, and in general discrete math, while the other machine (solving differential equations in a grapho-mechanical way) involves the complementary concepts of continuous math: curves, tangents, derivatives. In this paper we will just present the machines, deepening the ideas and the subtended mathematical contents, but we will…
Dal liceo all’università: una ricerca-intervento per la costruzione del progetto di vita professionale degli studenti
2019
Si è conclusa nel mese di maggio del 2019 la prima parte di una ricerca-intervento ispirata alla teoria del pensiero narrativo, ai principi dell’educational counseling e della didattica orientativa. Durante l’anno scolastico 2018-2019, 93 studenti (50 femmine e 43 maschi) del quarto anno di cinque licei di Palermo hanno partecipato a un’iniziativa sperimentale in cui scuola e università hanno collaborato con un duplice scopo: ridurre negli studenti il gap rilevato tra le conoscenze in uscita dal liceo e quelle richieste all’inizio dei corsi universitari e potenziare in loro la capacità di formulare il proprio progetto di vita professionale. È stata sperimentata l’azione congiunta di tre tip…
Verifica dell'efficacia didattica di un percorso laboratoriale per l'insegnamento dell'italiano nelle scuole dell'infanzia e primaria
2010
Le attività formative del laboratorio di Didattica della lingua italiana, rivolto a futuri maestri, hanno inteso promuovere buone pratiche di insegnamento linguistico, stimolando la trasformazione delle conoscenze in abilità professionali. Il laboratorio ha inteso offrire agli studenti la possibilità di riflettere e rielaborare, di osservare e sperimentare tecniche operative, di mobilitare risorse per l’analisi, la progettazione e la simulazione di situazioni didattiche e di interventi educativi. La verifica dei risultati, eseguita con strumenti di rilevazione ed autovalutazione delle competenze, e l’esame delle risposte degli studenti sull’efficacia e il gradimento dell’esperienza sottolin…
Il laboratorio
2008
Il laboratorio designa una modalità di lavoro che, abbandona la logica del disciplinarismo e della settoralialità del sapere, a partire da problemi significativi per gli alunni, consente esperienze di soluzione degli stessi, utilizzando logiche e strategie pluri-inter-trans disciplinari.
DNA recovery from Droplet Digital™ PCR emulsions using liquid nitrogen
2020
Droplet microfluidics is a technology that enables the production and manipulation of small volumes. In biosciences, the most popular application of this technology is Droplet Digital™ PCR (ddPCR™), where parallel nanoliter-scale PCR assays are used to provide a high sensitivity and specificity for DNA detection. However, the recovery of PCR products for downstream applications such as sequencing can be challenging due to the droplets' stability. Here we compared five methods for disrupting the droplets to recover DNA. We found that rapid freezing in liquid nitrogen results in a clear phase separation and recovery of up to 70% of the DNA content. Liquid nitrogen freezing can thus offer a si…

Flow-bed interactions analysis and application of automatic close range digital photogrammetric survey in a laboratory flume
2014
This paper reports on a laboratory study in which the automatic digital photogrammetric survey was applied to derive the high-resolution Digital Surface Model (DSM) of the bed topography, used for the flow-bed interactions analysis, in a large amplitude meandering laboratory flume. The analysis has been conducted with the aid of detailed data of three-dimensional flow field previously collected using the acoustic Doppler velocity profiler DOP2000. The applied surveying procedure has allowed the evaluation of the DSM with a resolution of ±0.5 mm. The detailed DSM has been compared with peculiar maps describing the flow velocity pattern (downstream and the crossstream flows) and the shear vel…
Influence of Distance from the Host on Parasitisation by
2019
The olive fruit fly, Bactrocera oleae, is considered the main olive pest worldwide, and has been the target of biological control programmes through the release of the braconid parasitoid Psyttalia concolor. Laboratory tests were performed to evaluate the influence of distance from the host on parasitisation, placing larvae of the substitute host Ceratitis capitata at seven distances (0, 0.5, 1, 1.5, 2, 2.5, 3 mm) and four different time periods (7, 15, 30, 60 min). Moreover, field collected olives of Ogliarola Barese cultivar infested by B. oleae were exposed to P. concolor females to confirm its ability to parasitise B. oleae in small olives. Psyttalia concolor oviposition was inhibited a…
