Evaluation of efficacy and biocompatibility of a new absorbable synthetic substitute as a dural onlay graft in a large animal model.
2016
Numerous dura substitutes are commercially available, but no absorbable synthetic dura repair product has been used for both onlay and suture applications.The safety and effectiveness of a new absorbable synthetic substitute composed of Poly-L-lactide microfibers as onlay dural graft were evaluated.Physical properties and performance of the microfibrous synthetic dural substitute implanted as an onlay or suturable grafts were compared with these commercial products, including CODMAN ETHISORB™ Dura Patch and DuraGen™ Dural Graft Matrix, in a canine duraplasty model. The cerebrospinal fluid (CSF) leakage, macroscopic and microscopic observation at 30 and 90 days after implantation were invest…
Musiikin kuuntelu itsehoidollisena menetelmänä stressin lievityksessä
2016
Tämän tutkielman tarkoituksena oli tarkastella musiikin kuuntelua stressin lievityksessä arkipäivässä. Musiikin kuuntelun on todettu lievittävän stressiä tehokkaasti mutta aiemmat tutkimukset aiheesta ovat olleet lähinnä määrällisiä. Tässä tutkimuksessa aihetta lähestyttiin laadullisin menetelmin, jossa pyrittiin stressin lievityksen osalta kartoittamaan musiikillisten piirteiden lisäksi myös ihmisten kokemuksia aiheesta. Tutkimus toteutettiin haastattelemalla neljää henkilöä, jotka kuuntelivat musiikkia arkipäivässään stressin lievitykseen. Haastatteluaineisto analysoitiin sisällönanalyysin keinoin. Tutkimustulosten myötä havaittiin, että stressin lievityksessä musiikin tärkeimmät piirteet…

Female unemployment in an emerging economy : A study of online social support as a coping strategy
2021
The increased use of social media has resulted in active participation of women on social media platforms, specifically Facebook, Twitter, and Instagram. However, very little research has been carried out, specifically, on how women cope with the challenges of unemployment using social media networks. Thus, many women resort to different means as a coping strategy during their unemployment. In the face of rapid diffusion of social platforms, it is unclear how women personality traits influence their use of the social media. Similarly, it is also unclear how women’s experiences with these social networks, as a medium of online social support, serve as a coping strategy in the period of unemp…
Intrinsic spin-orbit interaction in diffusive normal wire Josephson weak links: Supercurrent and density of states
2016
We study the effect of the intrinsic (Rashba or Dresselhaus) spin-orbit interaction in superconductor–nanowire–superconductor (SNS) weak links in the presence of a spin-splitting field that can result either from an intrinsic exchange field or the Zeeman effect of an applied field. We solve the full nonlinear Usadel equations numerically [The code used for calculating the results in this paper is available in https://github.com/wompo/Usadel-for-nanowires] and analyze the resulting supercurrent through the weak link and the behavior of the density of states in the center of the wire. We point out how the presence of the spin-orbit interaction gives rise to a long-range spin triplet supercurr…
Optical Properties of III-V Nanowires and Their Application for Charge Transport and Single-Photon Emission
2012
This work covers the optical characterization of III-V semiconductor nanowires and their application for charge transport and for single-photon emission. InAs nanowires have been investigated by Raman scattering and PL spectroscopy. The possibility to grow nanowires with a crystal structure different from its bulk counterpart has aroused a lot of interest in their optical and electronic properties. Here, the optical phonon modes of wurtzite InAs nanowires have been studied by polarized Raman scattering. For the first time, Raman measurements on a single InAs nanowire have revealed the A1(TO) and E2h optical phonon modes of the wurtzite structure. Additional resonant Raman scattering experim…
Going through the lockdown: a longitudinal study on the psychological consequences of the coronavirus pandemic
2021
Coronavirus 2019 pandemic lockdown in Italy lasted for 2 months, 1 week and 2 days. During this long period, one of the longest in Europe, the restrictions produced effects on people’s psychological well-being, with consequences that also continued after lockdown. The purpose of the study is to investigate these effects and how they changed in the general population over a period of time. We are also interested in exploring people’s post-lockdown anxiety and concerns. We conducted an online survey using snowball sampling techniques. The longitudinal study consisted of four administrations covering a period of 10 weeks between April (baseline) and June (last follow-up). Levels of anxiety and…
The contribution of the pre-existing structures in mountain belt evolution: the example of the negative inversion in the Northen Sicily
2004
Syn-orogenic extension has been recognised in Northern Sicily. Mesoscopic analysis has been carried out in three key areas, where folded-and-thrust Mesozoic-to-Tertiary rocks crop-out. The three examples are inherent to Portions Of tectonic Units Which occupy progressively more internal positions in the Sicilian chain from west to east. The extensional deformation is mainly represented by low-angle normal faults and shear bands. A common kinematic process seems to affect the other sector of the chain during the extension and is represented by a generalized negative inversion of previous layer-parallel shear bands and detachments related to the thrusting. The extensional deformation occurred…
Copioni sessuali, devianza e neutralizzazione dello stigma nel sex work maschile
2016
Nel presente saggio sono trattate le questioni relative al «discorso sui motivi sessuali» e alle forme di neutralizzazione utilizzate dai soggetti all’interno della «carriera» del sex working. Nelle conclusioni indicheremo, inoltre, la necessità di approcci integrati che tengano conto delle basi dell’interazione oltre ai principali temi emergenti relativi alla strutturazione di genere, sessuale e razziale.
Nuclear structure and neutrino-nucleus reactions at supernova energies
2015
Supernova-(anti-)neutrino–nucleus scattering is discussed with reference to neutral-current (NC) and charged-current (CC) processes in heavy stable nuclei. The Donnelly-Walecka method with the associated multipole expansion of the nucleonic current has been adopted as the basic framework in deriving the neutrino-nucleus scattering cross sections. The needed nuclear wave functions are computed by using the quasiparticle random-phase approximation (QRPA) for the even-even target nuclei in the NC processes and the proton-neutron QRPA (pnQRPA) has been used to compute the CC processes for the mentioned nuclei. The wave functions of the stable odd-mass target nuclei have been obtained by the use…
