Sonication-Induced Modification of Carbon Nanotubes: Effect on the Rheological and Thermo-Oxidative Behaviour of Polymer-Based Nanocomposites.
2018
The aim of this work is the investigation of the effect of ultrasound treatment on the structural characteristics of carbon nanotubes (CNTs) and the consequent influence that the shortening induced by sonication exerts on the morphology, rheological behaviour and thermo-oxidative resistance of ultra-high molecular weight polyethylene (UHMWPE)-based nanocomposites. First, CNTs have been subjected to sonication for different time intervals and the performed spectroscopic and morphological analyses reveal that a dramatic decrease of the CNT's original length occurs with increased sonication time. The reduction of the initial length of CNTs strongly affects the nanocomposite rheological behavio…
Advances in Nanoliposomes Production for Ferrous Sulfate Delivery
2020
In this study, a continuous bench scale apparatus based on microfluidic fluid dynamic principles was used in the production of ferrous sulfate-nanoliposomes for pharmaceutical/nutraceutical applications, optimizing their formulation with respect to the products already present on the market. After an evaluation of its fluid dynamic nature, the simil-microfluidic (SMF) apparatus was first used to study the effects of the adopted process parameters on vesicles dimensional features by using ultrasonic energy to enhance liposomes homogenization. Subsequently, iron-nanoliposomes were produced at different weight ratios of ferrous sulfate to the total formulation components (0.06, 0.035, 0.02, an…
Evaluation of the Behavior of Phenolic Compounds and Steviol Glycosides of Sonicated Strawberry Juice Sweetened with Stevia (Stevia rebaudiana Berton…
2019
In this study, the influence of stevia addition and sonication processing parameters on the phenolic content and profile as well as the steviol glycosides of strawberry juice-based samples was investigated. For this purpose, three matrices&mdash
Shoulder ultrasound: current concepts and future perspectives
2021
Ultrasonography is an established and effective imaging technique that can be used to evaluate articular and periarticular structures around the shoulder. It has been shown to be useful in a wide range of rotator cuff diseases (e.g. tendon tears, rotator cuff calcific tendinopathy and bursitis) as well as non-rotator cuff abnormalities (instability, synovial joint diseases and nerve entrapment syndrome). A scanning protocol is highly recommended to reduce the rate of operators’ errors by following a standardized scheme including a list of main structures. Shoulder ultrasound has several advantages: it is a relatively cheap and widely available technique, free from ionizing radiation, that c…
Mediated communication as an entryway into interculturality
2022
In this chapter, the authors discuss how utilising mediated communication may open new possibilities into exploring and understanding intercultural communication in education. Set in the context of Finnish higher education, the chapter follows a social constructionist viewpoint into mediated communication. The chapter argues for the prevalence of media and technology-mediated communication as a tool with which citizens of a globalised world make sense of themselves as well as the other. The authors present and discuss practical examples of how learners’ own media use practices may be drawn upon in teaching, and how focusing on the everyday affordances of media allows for strengthening learn…
The use of Electronic Information Systems in social work : A scoping review of the empirical articles published between 2000 and 2019
2022
Sähköisiä tietojärjestelmiä käytetään laajasti sosiaalityössä, mutta empiirisiä tutkimustuloksia niiden käytöstä ei ole vielä analysoitu ja levitetty. Tässä kartoittavassa kirjallisuuskatsauksessa tarkasteltiin vuosien 2000–2019 julkaistun 36 tutkimusartikkelin tuloksia selvittäen, mitkä teemat korostuivat tutkimuksissa sekä millaisia tutkimusaukkoja oli tunnistettavissa. Analyysin perusteella tunnistettiin neljä pääteemaa: (1) tietojärjestelmien käytön vaikutukset sosiaalityöhön; (2) tekijät, joilla on vaikutusta tietojärjestelmien käytössä; (3) sosiaalityöntekijöiden toimintatavat tietojärjestelmien käytössä ja (4) tietojärjestelmien kehittäminen sosiaalityöntekijöiden kanssa. Tulosten mu…
Framtidas eldre - hva mener de egentlig om velferdsteknologi? : En studie om holdninger til teknologi i morgendagens helsetjeneste
2017
Masteroppgave i helse- og sosialinformatikk HSI500 - Universitetet i Agder 2017 Background: In 2040 the number of elderly (< 80 years) will double. Welfare technology is introduced as one of the solutions to the challenges health care is facing (Parliamentary report 29 (2012-2013)). There is little data on the elderly’s attitudes about services in the years to come and their attitudes toward welfare technology.Aim: The aim of the study was to mapattitudes towardwelfare technology among the future generation of elderlyin the municipality of Grimstad, as well as to assess predictors for positivetechnology attitudes.Research method: On the basis of Theory of planned behavior (Ajzen, 1985),aque…
Cooperative sound design: a protocol analysis
2016
Formal protocol analysis and linkographic representations are well-established approaches in design cognition studies, in the visual domain. We introduce the method and tools in the auditory domain, by analysing a case of collaborative sound design. We show how they can provide relevant qualitative and quantitative information about the efficiency of the creative process.
Numerical methods for a nonlinear impact model: A comparative study with closed-form corrections
2011
A physically based impact model-already known and exploited in the field of sound synthesis-is studied using both analytical tools and numerical simulations. It is shown that the Hamiltonian of a physical system composed of a mass impacting on a wall can be expressed analytically as a function of the mass velocity during contact. Moreover, an efficient and accurate approximation for the mass outbound velocity is presented, which allows to estimate the Hamiltonian at the end of the contact. Analytical results are then compared to numerical simulations obtained by discretizing the system with several numerical methods. It is shown that, for some regions of the parameter space, the trajectorie…
