PQ and Harmonic Assessment Issues on Low-Cost Smart Metering Platforms: A Case Study
2020
This paper presents a feasibility study on how to implement power quality (PQ) metrics in a low-cost smart metering platform. The study is aimed at verifying the possibility of implementing PQ monitoring in distribution networks without replacing existing smart metering devices or adding new modules for PQ measurements, thus zeroing the installation costs. To this aim, an electronic board, currently used for remote energy metering, was chosen as a case study, specifically the STCOMET platform. Starting from the specifications of this device, the possibility of implementing power quality metrics is investigated in order to verify if compliance with standard requirements for PQ instruments ca…
Assessment of the moisturizing potential of a two-phase topical care product containing vegetable oils, glycerin, panthenol, and sodium hyaluronate -…
2022
The presence of moisturizing substances and lipid substances determines the integrity of the epidermis cells and their barrier functions because it protects the interior of the body against environmental changes: temperature, humidity, ultraviolet radiation, pollution, and the effects of detergents. In this study, we performed a non-invasive, preliminary evaluation of the effects of a biphasic facial skin care product containing plant oils, hyaluronic acid, glycerin, and panthenol on skin hydration levels and transepidermal water loss compared to a control group using only shea butter. The topical care product formed as a two-phase emulsion was tested. The research was carried out with the …
At the interface between sensation and emotion : perceived qualities of single chords
2017
The focus of this dissertation is to investigate the perception of single chords, both in terms of perceived emotions and psychoacoustic qualities. Previous empirical research on harmony perception has mainly been concerned with horizontal aspects of harmony: studies focusing on vertical harmony perception have been rare. The current work aims to fill some of the still evident gaps between musicology, music psychology, and psychoacoustics with regard to single chord perception by combining both empirical and theoretical approaches. The work comprises three publications, based on two large-scale empirical experiments conducted with the aim of drawing the attention of both expert and inexpert…
Johtosävelen tuolla puolen : aiolinen sointukulku populaarimusiikissa
2013
Tässä tutkielmassa tutkitaan yhdenlaista aiolista sointukulkua populaarimusiikissa. Sointukulus-sa ensimmäinen sointu i ja viimeinen sointu bVII aste. Tarkoituksena on löytää sointukulun alku-perä ja lähtökohta sekä sointukulun tyypillisin muoto. Sointukulkuja tarkastellaan erilaisten musiikinteorioiden kautta. Päänäkökulman on psykologias-ta skeemateoria sekä pohdintaan genren merkitystä sointukulkuun. Perinteisen musiikkiteorioi-den avulla luodaan lähtökohdat tarkastelulle. Skeemateorian avulla voidaan tarkastella sointuku-lun historiaa sekä sointukulun rakennetta ja ulottuvuuksia. 1980-luvun puoli välissä ilmestynyt Iron Maidenin Aces High -kappale näyttäisi sisältävän tä-män sointukulku…

Metsäkukkia juurineen : menetelmiä harmonikansoiton aikuispedagogiikkaan
2011
Musiikkipedagogiikka pohtii oppimista perinteisesti lasten ja nuorten kautta. Tutkielmassani kuitenkin lähestyn erilaisia oppimisen käsitteitä aikuisen harmonikansoiton harrastajan näkökulmasta ja pyrin löytämään heille sopivat harjoitusmetodit, jotka auttaisivat motivoitumaan, harjoittelemaan oikein ja hallitsemaan paremmin harmonikan soittotekniikkaa. Käsittelen myös harmonikan syntyvaiheita, sen musiikillisen kehityksen historiaa, rakennetta, soittoteknisiä mahdollisuuksia ja analysoin harmonikansoiton aiempia oppimateriaaleja ja tutkimuksia. Tutkimukseni kohdistuu aikuisten harmonikansoittajien musiikillisten tavoitteiden mukanaan tuomiin haasteisiin ja niiden ratkaisemiseen. Aikuisten …
Synthesis and Biological Evaluation of a Multiantigenic Tn/TF-Containing Glycopeptide Mimic of the Tumor-Related MUC1 Glycoprotein

Combined Use of Structure Analysis, Studies of Molecular Association in Solution, and Molecular Modelling to Understand the Different Propensities of…
2021
The arrangement of hydroxyl groups in the benzene ring has a significant effect on the propensity of dihydroxybenzoic acids (diOHBAs) to form different solid phases when crystallized from solution. All six diOHBAs were categorized into distinctive groups according to the solid phases obtained when crystallized from selected solvents. A combined study using crystal structure and molecule electrostatic potential surface analysis, as well as an exploration of molecular association in solution using spectroscopic methods and molecular dynamics simulations were used to determine the possible mechanism of how the location of the phenolic hydroxyl groups affect the diversity of solid phases formed…
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…
