Rilievi e indagini diagnostiche non distruttive per l’individuazione delle cripte - La Cattedrale di Ragusa
2014
I diversi operatori, che si occupano di Beni Storici e Culturali, si avvalgono sempre più spesso delle soluzioni tecnologiche avanzate offerte dalla moderna Geomatica, facendo ricorso ad integrazioni delle sue discipline, per meglio studiare, indagare e monitorare un bene di interesse storico. Oggi si tentano nuove integrazioni con altre discipline che, tradizionalmente, non riguardano il campo del rilievo propriamente detto. Questo è, ad esempio, il caso dello studio condotto sulla Cattedrale di San Giovanni a Ragusa, nel quale si è partiti dal rilievo laser scanning di una porzione della chiesa e del suo pregiatissimo pavimento, sotto il quale secondo uno schizzo dei primi anni del XIX se…
All polarization-maintaining assively mode-locked yb-doped fiber laser : pulse compression using an anomalous polarization-maintaining photonic cryst…
2019
We report the generation of short pulses at 1 μm using an all-polarization-maintaining (PM) fiber configuration. The pulses are provided by an all normal-dispersion Fabry-Perot Yb-doped cavity and are compressed with an anomalous polarization-maintaining photonic crystal fiber (PM PCF). Opposed to standard configurations; here the filtering action is solely performed by the finite bandwidth of the gain medium. The laser generates 8 ps width sech 2 profile pulses at 1046.8 nm with a −10 dB bandwidth of 5.9 nm. After compression using the PM PCF, pulses with an FWHM of 3 ps were obtained, limited by the actual value of the available anomalous dispersion. We also report the changes in the outp…
All-Fiber Laser With Intracavity Acousto-Optic Dynamic Mode Converter for Efficient Generation of Radially Polarized Cylindrical Vector Beams
2017
We report an all-fiber laser that emits a radially polarized cylindrical vector beam (CVB) at 1 μm based on an intracavity acousto-optic mode converter. We efficiently generate the CVB, taking advantage of the acousto-optic coupling from the HE11 mode to the TM01 mode in a two-mode fiber. The laser can be switched from emitting a Gaussian-like beam to a radially polarized CVB. Radially polarized CVBs with modal and polarization purities >98% and a maximum power of 65 mW were generated.
Dynamic of Components Leachate from Experimental Fertilizers in Leaching Test
2018
Organic matter contained in the waste of food industry or occurring in the households, in the absence of contamination with other kind of waste, may be used to create a “fertiliser”, which could be even reused in the organic production of arable crops. Particular attention is drawn to the fertilisers which may be applied in the case of amateur cultivation of pot plants and in the allotment gardens. The paper presents the results of research regarding the dynamics of the release of nutrients from tablets created with the help of encapsulation of the mixture manufactured from solvent extraction waste of coffee (SCG), modified by the ash obtained from low temperature burning of biomass. In thi…

Nye litteraturer: Litterære tekstpraksiser hos voksne innvandrere i norsk grunnskoleopplæring
2020
Voksne innvandrere som tar norsk grunnskoleeksamen har teksterfaringer fra litteraere tradisjoner som kan vaere ukjente i var sammenheng. Basert pa naermere tyve enkeltintervjuer undersoker denne studien bade tidligere og navaerende litteraere tekstpraksiser hos informanter fra Syria, Eritrea og Somalia. Ett av studiens funn er at enkelte informanter med svaert lite skolegang likevel har aktive litteraere tekstpraksiser. Imidlertid vil de fleste litteraere tekstpraksisene sannsynligvis ikke bli gjenkjent i skolesammenheng, ettersom de opptrer utenfor skolens domene og bare unntaksvis er knyttet til trykte, papirbaserte tekster, som boker. I stedet er youtube det mest brukte mediet. Studien …
Fra behandling til recovery. En review-studie av forskning på dagsentra for mennesker med psykiske lidelser
2017
This study reviews research publications topically related to day centres for people with mental health problems. The purposes are to give a general overview of the evidence-based knowledge in the field, to detect gaps of knowledge, and to throw light on the following research questions: (1) Which ideologies about day centres may be revealed in Scandinavian- and English-speaking research on day centres for people with mental health problems; and (2) What significance do the day centres have for the users?Both questions are answered by examining 34 research publications, printed in either Scandinavian or English languages during the period 1962-2015. An integrative literature review was used…
State of the art and prospects for halide perovskite nanocrystals
2021
Financiado para publicación en acceso aberto: Universidade de Vigo/CISUG Metal-halide perovskites have rapidly emerged as one of the most promising materials of the 21st century, with many exciting properties and great potential for a broad range of applications, from photovoltaics to optoelectronics and photocatalysis. The ease with which metal-halide perovskites can be synthesized in the form of brightly luminescent colloidal nanocrystals, as well as their tunable and intriguing optical and electronic properties, has attracted researchers from different disciplines of science and technology. In the last few years, there has been a significant progress in the shape-controlled synthesis of …
Kannustin, koriste ja liikkujan kaveri : tutkimus liikuntateknologian käyttäjyydestä
2017
During the last couple of decades, information technology has become a ubiquitous part of almost all areas of everyday life; exercise and sports being no exception. Sports technology can be defined as digital entities, with which one can measure, record and analyse data on sports and physical activity, and refine it according to the needs of its users. This kind of technology has already been researched quite extensively. The majority of this research has concentrated on the effects of sports technology on the level of physical activity of its users, and on the adherence of users to different kinds of physical activity recommendations. In addition to this, within this research, sports techn…
