Evaluation of alveolar cortical bone thickness and density for orthodontic mini-implant placement.
2013
Objective: Mini-implant stability is primarily related to bone quality and quantity. This study evaluated alveolar cortical bone thickness and density differences between interradicular sites at different levels from the alveolar crest, and assessed the differences between adolescents (12-18 years of age) and adults (19-50 years of age), males and females, upper and lower arch, anterior and posterior region of jaws and buccal and oral side. Study Design: In this retrospective study, 48 Computed Tomography scans, performed for oral surgery purposes were selected from dental records of 3,223 Caucasian orthodontic patients. The SimPlant software (Materialise, Leuven, Belgium) was used to measu…
Feasibility of conductive embroidered threads for I 2 C sensors in microcontroller-based wearable electronics
2023
Abstract In recent years, the importance of flexible and textile electronics in the field of wearable devices has continuously increased, as they are expected to replace conventional wires that exhibit limited resistance to the mechanical stress occurring in on-body applications. Wearable health devices (WHDs) can provide physiological information about various body parts and employ distributed sensor networks. Among the sensors typically integrated within WHDs, those based on the I2C communication protocol are very common and exploit signals transmitted at frequencies up to hundreds of kilohertz. Therefore, robust communication is required to guarantee a proper transmission of the signal a…
Overview of Power Electronic Switches: A Summary of the Past, State-of-the-Art and Illumination of the Future.
2020
As the need for green and effective utilization of energy continues to grow, the advancements in the energy and power electronics industry are constantly driven by this need, as both industries are intertwined for obvious reasons. The developments in the power electronics industry has over the years hinged on the progress of the semiconductor device industry. The semiconductor device industry could be said to be on the edge of a turn into a new era, a paradigm shift from the conventional silicon devices to the wide band gap semiconductor technologies. While a lot of work is being done in research and manufacturing sectors, it is important to look back at the past, evaluate the current progr…
Näkövammaisten apuvälineiden käytettävyys
2015
Näkövammaisille apuvälineet ovat elämää helpottavia, hyödyllisiä, pakollisia, kiusallisiakin mutta välttämättömiä. Ne tarjoavat mahdollisuuden itsenäiseen elämään, harrastamiseen ja työskentelyyn ihmisille, joille se ei ilman olisi mah-dollista. Tutkimuksessa halusin selvittää, millä tasolla näkövammaisten apuvälineiden käytettävyys on tällä hetkellä ja mitä parannettavaa siinä olisi tulevaisuudessa. Tarkoitus oli myös selvittää, mitä apuvälineitä näkövammaiset oikeasti käyttävät. Erityishuomiota tutkimuksessa saivat liikkumisen apuvälineet. Selvittääkseni näitä asioita suoritin käyttäjäkyselyn varsinaiselle käyttäjäryh-mälle. Tämä tehtiin näkövammaisten keskustelufoorumin kautta sähköisest…
The rhetorical construction of Hillary Rodham Clinton as a presidential contender in 2016: A case study of hillaryclinton.com
2016
Niniejsze studium poświęcone jest retorycznym sposobom konstruowania obrazu kandydatki na prezydenta USA Hillary Rodham Clinton podczas pierwszej fazy kampanii 2016 roku. Kontekstem studium jest literatura na temat różnic genderowych w dyskursie politycznym, a w szczególności badania poświęcone medialnym reprezentacjom kobiet w polityce, z których wynika, że kobiety, przynajmniej w USA, muszą bardziej aktywnie niż mężczyźni kreować swój publiczny wizerunek. Za pomocą perspektywy retorycznej, zbadano strategiczny sposób konstruowania i kontrolowania publicznego obrazowania Hillary Clinton w reakcji na przedstawienia jej kandydatury przez media głównego nurtu. Analizie poddano materiały tekst…
