Compost Amendment Impact on Soil Physical Quality Estimated from Hysteretic Water Retention Curve

2022

Capacity-based indicators of soil physical quality (SPQ) and pore distribution parameters were proposed to assess the effects of compost amendment but their determination was limited to desorption water retention experiments. This study also considered the pore size distribution obtained from adsorption experiments to establish the effectiveness of compost amendment in modifying the physical and hydrological attributes of a sandy loam soil. Repacked soil samples with different compost to soil ratios, r, were subjected to a wetting–drying cycle, and the water retention data were fit to the van Genuchten model to obtain the pore volume distribution functions. The soil bulk density was m…

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…

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…

Turning experience into expertise : technologies of the self in Finnish participatory social policy

2017

This article investigates the micro-level practices of subject-construction in Finnish participatory social policy. Through a governmental ethnography on projects that invite former beneficiaries to become ‘experts-by-experience’ in social welfare organizations, I discern the possibilities for freedom in the participants’ self-construction. By making use of Michel Foucault’s conceptual tools of care of the self and confession, I illustrate how, contrary to the projects’ emancipatory promise of providing the service users the freedom to reconstruct themselves, the projects entail practices that curb the participants’ way of ‘knowing themselves’. They require the service users to reframe thei…

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…
