'We have a solution': Delivering on the promise to take national responsibility for nuclear waste management

2022

We examine the realization of the umbrella promise to assume national responsibility for the final disposal of spent nuclear fuel. Three case studies are used to illustrate how Finland delivers on the promise to take care of its own nuclear waste - a promise that has greatly contributed to the legitimacy of nuclear power in Finland. The article shows how this promise is being challenged by new competitors, business visionaries, and the public. The case studies illustrate the tensions between those who made the promise and the actors who interpret and mobilize the promise for varying purposes and under changing circumstances. We investigate techno-scientific promises by looking at debates ab…

Fundamental movement skill proficiency and body composition measured by dual energy X-ray absorptiometry in eight-year-old children

2014

Objective: The main aim was to examine the association between fundamental movement skills (FMS) and objectively measured body composition using dual energy X-ray absorptiometry (DXA). Methods: Study of 304 eight-year-old children in Finland. FMS were assessed with the Test of Gross Motor Development, 2nd ed. (TGMD-2). Total body fat percentage (BF%), abdominal region fat percentage (AF%), and fat-free mass (FFM) were assessed by DXA. Waist circumference, height and weight were measured and International Obesity Task Force (IOTF) cut-off values for BMI were used for the definition of healthy weight and overweight/obesity. Results: Better FMS proficiency (object-control, locomotor, total FMS…

Pirmsslodzes ogļhidrātu uzņemšanas ietekme uz glikozes līmeni asinīs submaksimālas slodzes laikā

2019

Maģistra darba mērķis ir izpētīt pirmslodzes uzņemto ogļhidrātu ietekmi uz glikozes līmeni venozajās asinīs un to potenciālo ietekmi uz darba spējām submaksimālas slodzes laikā. Pētījuma ietvaros glikozes līmenis venozajās asinīs tika mērīts 8 sportistiem. Glikozes mērījums tika veikts 4 atsevišķos eksperimentālos testos - Glikozes tolerances mērījums, Glikozes līmeņa izmaiņas venozo asiņu plazmā submaksimālas slodzes laikā; Pirmslodzes ogļhidrātu ietekme uz glikozes līmeni venozo asiņu plazmā, tos uzņemot 45min pirms fiziskas slodzes; Pirmslodzes ogļhidrātu ietekme uz glikozes līmeni venozo asiņu plazmā, tos uzņemot 15 min pirms fiziskas slodzes. Glikozes mērījums tika veikts ar glikometru…

Solvatochromic behaviour of new donor–acceptor oligothiophenes

2021

Oligothiophene derivatives play a central role in the formulation of materials used in devices in the field of organic electronics. In this work, we report the results of the study of UV-vis absorption and fluorescence spectra, in several solvents, of a series of oligothiophenes recently synthesized in our laboratory. The studied oligothiophenes present different structures due to several factors: the donor– acceptor (D–A) or acceptor–donor–acceptor (A–D–A) architecture, the number of thiophene rings in the backbone (ranging from three to eight), the number and position of solubilizing octyl chains in the backbone, and the type of acceptor moieties (from Knoevenagel condensation either with…

WRKY gene family drives dormancy release in onion bulbs

2022

Onion (Allium cepa L.) is an important bulb crop grown worldwide. Dormancy in bulbous plants is an important physiological state mainly regulated by a complex gene network that determines a stop of vegetative growth during unfavorable seasons. Limited knowledge on the molecular mechanisms that regulate dormancy in onion were available until now. Here, a comparison between uninfected and onion yellow dwarf virus (OYDV)-infected onion bulbs highlighted an altered dormancy in the virus-infected plants, causing several symptoms, such as leaf striping, growth reduction, early bulb sprouting and rooting, as well as a lower abscisic acid (ABA) level at the start of dormancy. Furthermore, by compar…

Perceived reason to hinder ACAP increase

2014

We derive through literature review that lack of internal R&D investment, lack of contribution into absorptive capacity (ACAP) nurturing at the initial phase of a project, and lack of adequate training prevent ACAP improvement. We conduct 41 interviews using a case study method on four organizations. Based on the empirical findings, it is revealed that most of practitioners know how ACAP can be improved. But still, they do not offer the important incentives and follow some traditional ways of performing their tasks. We further explore what prevents practitioners from implementing practices towards ACAP improvement. From our empirical findings we identify and analyze perceived reasons that h…

Predicting tire/pavement noise impact reduction using numerical simulation and experimental data for open graded asphalt mixture

2013

The environmental impact of noise from roads and highways traffic is relevant in urban and rural areas. The use of open-graded asphalt pavements reduces significantly the noise, entrapping the acoustic waves inside the porous structure of the material. In this paper we propose a simulation approach in order to predict the acoustic properties of the asphalt mixture from geometrical and topological indicators. In detail we have generated, using a Random Sequential Adsorption model, synthetic samples starting from the same grading and bitumen contents of real samples manufactured in laboratory. We have measured the acoustic adsorption coefficient of the real samples and we have investigated th…

Modeling epidemics through ladder operators

2020

Highlights • We propose an operatorial model to describe epidemics. • The model describes well the asymptotic numbers of the epidemics. • Ladder operators are used to model exchanges between the “actors” of the system.

Eye-Movement Study of Mechanics Problem Solving Using Multimodal Options

2020

We used an eye-tracking method to investigate students’ approaches to solving a physics task using various representations. Eight upper-secondary school students from Finland took part in the study. We found that students who preferred either the text or graph representations watched the options differently, but they used both representations to be sure of their solution. Transitions between text and graph alternatives were different for students preferring either text or graph representations. Interviews revealed typical misconceptions about the concept of force. Implications for physics instruction are presented. peerReviewed
