Quantitative Multispectral Imaging Differentiates Melanoma from Seborrheic Keratosis.
2021
Melanoma is a melanocytic tumor that is responsible for the most skin cancer-related deaths. By contrast, seborrheic keratosis (SK) is a very common benign lesion with a clinical picture that may resemble melanoma. We used a multispectral imaging device to distinguish these two entities, with the use of autofluorescence imaging with 405 nm and diffuse reflectance imaging with 525 and 660 narrow-band LED illumination. We analyzed intensity descriptors of the acquired images. These included ratios of intensity values of different channels, standard deviation and minimum/maximum values of intensity of the lesions. The pattern of the lesions was also assessed with the use of particle analysis. …
An Inquiry-Based Approach to a Pedagogical Laboratory for Primary School Teacher Education
2017
In questo articolo vengono presentati e di- scussi alcuni risultati relativi alla sperimen- tazione di due esperienze di didattica laboratoriale della fisica, una basata su me- todi di indagine scientifica e l’altra su meto- dologie didattiche più “tradizionali”, svolte durante l’A.A. 2014-15 con studenti del CdL in Scienze della Formazione Primaria del- l’Università di Palermo. I dati, analizzati tra- mite metodi quantitativi, sono stati ricavati dalla somministrazione prima, durante e do- po le attività laboratoriali, di un questionario finalizzato a comprendere gli stili di insegna- mento preferiti dagli studenti, la motivazio- ne di questi all’apprendimento/insegna- mento delle scienze …
Elaboración un instrumento para conocer las características de la banda sonora de la programación infantil de televisión
2014
Television is one of the most important elements in the construction of the musical and audible reality of children and teenagers. It offers a selected and edited version of a musical environment, with an indisputable level of communicative and patrimonial influence. This paper is part of a research project that sets out to know what children are listening to in children’s television programming, in a sample of Latin American television coverage. The general objective has been to establish the parameters of everyday listening experiences and to create an instrument which is able to determine the objective elements of listening environments through their most notable medium: the soundtrack o…
Salikteņi rakstos par tirgvedību
2018
Rakstība angļu valodā vienmēr ir bijusi diezgan sarežģīta. Salikteņi ir vārdi, kam nav noteiktas rakstības sistēmas, tādēļ cilvēki tos raksta dažādi. Tādējādi šī darba mērķis ir analizēt salikteņus rakstos par tirgvedību. Kvalitatīvā un kvantitatīvā analīze tika izmantota kā pētniecības metode, un analīze tika veikta par salikteņiem, kas atrodami rakstos par tirgvedību vienā britu un vienā amerikāņu tirgvedības žurnālā. Šis pētījums ir parādījis, ka pārstāvētākais salikteņu veids ir īstie salikteņi (proper compounds) un izplatītākā salikteņu rakstība ir tos rakstīt kā vienu vārdu jeb “koprakstījumā” (solid compounds). Pētījuma rezultāti apstiprina, ka rakstos par tirgvedību izmantoto salikt…
