Performance Enhancement of a Small Animal Positron Emission Tomograph based on Continuous Crystals and Silicon Photomultipliers

2017

La tomografía por emisión de positrones (PET, por sus siglas en inglés) es una técnica de Medicina Nuclear que permite obtener de manera no invasiva imágenes funcionales “in vivo” marcando un compuesto orgánico con un emisor de positrones. Los tomógrafos PET requieren un alta resolución espacial y sensibilidad para estimar con precisión la distribución del radiotrazador en el animal. Frente a los bloques pixelados comúnmente utilizados en PET, los detectores que consisten en la combinación de cristales continuos acoplados a fotodetectores segmentados pueden ofrecer una mayor eficiencia y una alta resolución espacial. Esta última depende de la precisión de los algoritmos de determinación de …

Soitonopettajan rooli oppimismotivaation vahvistajana taiteen perusopetuksessa : opettajan ja oppilaan välinen vuorovaikutus viulunsoitonopetuksessa …

2017

The aim of this study is to find tools for the instrument teacher to support the student's learning motivation. The research is set in the cultural region of Central Ostrobothnia. The research material consists of a survey conducted by means of a questionnaire, recorded video footage of lessons given by three violin teachers, and a total of eight interviews with these teachers and their students. The data was analyzed using both quantitative and qualitative methods. The study reveals that the most important motivation factor is the sense of relatedness of the pupil. The key factor is a close relationship between the pupil and the teacher, which allows the teacher to engage the pupil in the …

Identifying the Impact of Game Music both Within and Beyond Gameplay

2021

This paper presents an overview of and a brief critical reflection on game music’s impact on players both within and beyond the context of gameplay. The analysis is based both on the current literature as well as on preliminary (work-in-progress) observations of our research project Game Music Everyday Memories. We consider how the functions and uses of game music potentially extend to people’s everyday life, thus constituting a personally and culturally meaningful relationship with music that is not immediately connected to gameplay. On the other hand, we consider the ways game music and a person’s attachment to the music are involved in gameplay motivation and potential game retention. As…

Conceptualizing ecosystem tipping points within a physiological framework

2017

Connecting the nonlinear and often counterintuitive physiological effects of multiple environmental drivers to the emergent impacts on ecosystems is a fundamental challenge. Unfortunately, the disconnect between the way “stressors” (e.g., warming) is considered in organismal (physiological) and ecological (community) contexts continues to hamper progress. Environmental drivers typically elicit biphasic physiological responses, where performance declines at levels above and below some optimum. It is also well understood that species exhibit highly variable response surfaces to these changes so that the optimum level of any environmental driver can vary among interacting species. Thus, specie…

‘Because I point to myself as the hog’ : interactional achievement of moral decisions in a classroom

2016

Abstract Drawing on the conversation analytic and sociocultural perspectives, this study investigates children's situated moral negotiations in classroom peer interaction in the absence of a teacher. The conversation analytic methodology is used to operationalise some of the key elements of the sociocultural perspective on moral development. In this way, this study enables readers to observe and study the semiotic, conversational and interactional mediations of moral functioning in real life, with the example of children's moral practices. The empirical analysis is based on video-recorded sequences in which primary school children work with the rules of a counting rhyme which is banned by t…

Interaction of allopurinol with phenprocoumon in man.

1977

Conditions in two patients on long-term phenprocoumon (Marcumar®) treatment are reported who had signs of phenprocoumon overdosage when given simultaneously allopurinol. The determination of phenprocoumon plasma concentrations in one patient showed that phenprocoumon accumulates for several weeks during treatment with allopurinol. Signs of phenprocoumon overdosage thus can appear long time after starting allopurinol treatment.

Significant interaction between high-dose methotrexate and high-dose piperacillin-tazobactam causing reversible neurotoxicity and renal failure in an…

2020

Introduction Pharmacokinetic interaction of high-dose methotrexate (MTX) and other concomitantly administered renally secreted medicinal products may lead to insufficient methotrexate serum level decrease and significant MTX toxicity. Case report We report the case of an 18-year-old male patient treated with high-dose MTX for an osteosarcoma and with high-dose piperacillin-tazobactam at the same time. MTX serum levels were severely elevated 24 hours after the MTX infusion and did not decrease in accordance with the specific calcium folinate rescue protocol. The patient experienced renal failure accompanied by neurological symptoms, most consistent with MTX-related renal and CNS toxicity. Ma…

Patterns of trunk spine growth in two congeneric species of acanthocephalan: investment in attachment may differ between sexes and species.

2012

SUMMARYAcanthocephalans have evolved a hooked proboscis and some taxa have trunk spines to attach to their definitive hosts. These structures are generated before being used, thus a key question is how investment in attachment could optimally be allocated through the ontogeny. The number and arrangement of hooks and spines are never modified in the definitive host, but it is unclear whether these structures grow during adult development. A comparison of the size of trunk spines between cystacanths and adults of Corynosoma cetaceum and C. australe indicated that spines grow in both species, but only in females, which also had significantly larger spines than males. This sexual dimorphism did…
