2004
-Objetivo: estudiar la frecuencia y el espectro de las manifestaciones orales de consumidores de drogas infectados por VIH en la región de Perm. -Sujetos: 104 consumidores de droga seropositivos (69 hombres, 35 mujeres; edades desde 15 a 32; 13 co-infectados con virus de la hepatitis) y 13 consumidores de droga con SIDA (7 hombres, 6 mujeres; edades entre 16 y 37; 12 co-infectados con virus de la hepatitis). -Resultados: las formas más frecuentes de lesiones de la mucosa oral en el grupo de pacientes infectados por el VIHcandidiasis (32.7%), lesiones herpéticas (15.4%), queilitis glandular (3.9%), estomatitis aftosa recidivante (2%). La linfadenopatía regional fue observada en el 31% de los…
Understanding Crowdturfing : The Different Ethical Logics Behind the Clandestine Industry of Deception
2017
Crowdturfing, the dark side and usually unnoticed face of crowdsourcing, represents a form of cyber-deception in which workers are paid to express a false digital impression. While such behavior may not be punishable under the jurisdiction of formal law, its consequences are destructive to the cohesion and trustworthiness of online information. The conceptual work at hand examines the current literature on the topic, and lays the foundation for a theoretical framework that explains crowdturfing behavior. We discuss crowdturfing through three ethical normative approaches: traditional philosophical ethics, business ethics, and codified rules. We apply these lenses to an illustrative example o…
Low-level environmental metal pollution is associated with altered gut microbiota of a wild rodent, the bank vole (Myodes glareolus)
2021
Mining and related industries are a major source of metal pollution. In contrast to the well-studied effects of ex-posure to metals on animal physiology and health, the impacts of environmental metal pollution on the gut mi-crobiota of wild animals are virtually unknown. As the gut microbiota is a key component of host health, it is important to understand whether metal pollution can alter wild animal gut microbiota composition. Using a combination of 16S rRNA amplicon sequencing and quantification of metal levels in kidneys, we assessed whether multi-metal exposure (the sum of normalized levels of fifteen metals) was associated with changes in gut microbiota of wild bank voles (Myodes glar…
Kinectin käyttö ympäristön- ja liikkeentunnistukseen
2012
Vilhunen, Eetu Kinectin käyttö ympäristön- ja liikkeentunnistukseen Jyväskylä: Jyväskylän yliopisto, 2012. Tietojärjestelmätiede, Kandidaatin -tutkielma Ohjaaja(t): Eskelinen , Matti Tämän tutkielman tarkoituksena on käsitellä Microsoftin kehittämää Kinect -sensoria ja sen hyödyntämistä ympäristön- ja liikkeentunnistukseen. Tutkimus pyrkii vastaamaan siihen, miten Kinectiä voidaan hyödyntää ympäristön- ja liikkeentunnistuksessa, sekä siihen mitä hyötyä tai haittaa Kinectin käytöstä voi olla. Aluksi käydään läpi hieman Kinectin historiaa sekä sen sisältämää teknologiaa. Tämän jälkeen käydään läpi tutkielman kannalta oleelliset konenäköön liittyvät termit. Tutkielman aikana käydään myös läpi …
Factors behind Leisure-Time Physical Activity Behavior Based on Finnish Twin Studies: The Role of Genetic and Environmental Influences and the Role o…
2014
Different approaches are being taken to clarify the role of various factors in the development of physical activity behaviors. Genetic studies are a new area of physical activity research and also the motives for physical activity have been widely studied. The purpose of this paper is to review the findings emerging from the longitudinal genetic studies on leisure-time physical activity and to evaluate the associations between motivational factors and leisure-time physical activity. The focus is to review recent findings of longitudinal Finnish twin studies. The results of the latest longitudinal Finnish twin studies point to the existence of age-specific genetic and environmental influence…
An IPMSM torque/weight and torque/moment of inertia ratio optimization
2014
In this paper, a torque/weight and torque/moment of inertia ratio optimization procedure for interior permanent magnet syncronous motors (IPMSMs) is presented. More in detail, a performance comparison between several IPMSM rotor structures has been carried out in order to determine the optimum geometry that can maximize the torque/weight and torque/moment of inertia ratios. A commercial motor, with known electrical and mechanical characteristics, has been taken as reference. Its rotor structure has been modified several times, obtaining different rotor geometries and, therefore, many IPMSM models with different electrical and mechanical characteristics. The finite element method (FEM) analy…
The Internationalization of B2B Digital Platform Providers : The Role of Cross-National Distance and Digital Characteristics
2020
Digitalization offers new opportunities and changes how firms can explore and enter new markets. Current literature has deepened our understanding of the internationalization process of digital-based firms, but it provides very little guidance on how the specific characteristics of digital artifacts enable and accelerate internationalization or of the role of crossnational distance and cultural difference. We use a longitudinal single-case approach to explore how a Business-to-Business (B2B) platform provider internationalized its operations from inception. The case study illustrates that the ongoing development of the digital service and the integration with new devices played an important…
Cross-border virtual teams, as seen from applied psychology & applied economy perspective. A Case study of a cross-cultural teaching program
2018
Podczas gdy komunikacja staje się coraz łatwiejsza dzięki rozprzestrzenianiu się technologii komunikacji przez Internet (ICT), coraz więcej firm i osób staje przed wyzwaniem (współ)tworzenia i zwiększania efektywności wirtualnych zespołów. Chodzi tutaj o grupy ludzi kontaktujące się między sobą wyłącznie przez Internet, bez kontaktów w realnym świecie. Pomimo licznych zalet, do których należą między innymi niskie lub wręcz zerowe koszty finansowe oraz niezwykła elastyczność tworzenia, przed wirtualnymi zespołami istnieje też wiele wyzwań, nie widocznych z zewnątrz. W bieżącym artykule omawiamy zalety programu zajęć, zaprojektowanego do wzmacniania umiejętności komunikacji w wirtualnych zesp…
Biodegradable Metal-Organic Framework-Based Microrobots (MOFBOTs).
2020
Microrobots and metal–organic frameworks (MOFs) have been identified as promising carriers for drug delivery applications. While clinical applications of microrobots are limited by their low drug loading efficiencies and the poor degradability of the materials used for their fabrication, MOFs lack motility and targeted drug delivery capabilities. The combination of these two fields marks the beginning of a new era; MOF‐based small‐scale robots (MOFBOTs) for biomedical applications. Yet, biodegradability is a major hurdle in the field of micro‐ and nanoswimmers including small‐scale robots. Here, a highly integrated MOFBOT that is able to realize magnetic locomotion, drug delivery, and selec…
