Measurement of Low Concentration of Nanosized Objects Suspended in a Liquid Medium
2018
The new optical scheme of refractometer with temperature stabilisation 10-2 °C is developed, which allows measuring a refractive index of the sample with accuracy not worse than 10-5; dependence of refraction index on concentration of SiO2 nanoparticles in liquid suspension is obtained within the framework of the research.
TECHNOLOGICAL DESIGN. THE INNOVATION IN THE METHOD
2018
The book presents reflections on the centrality of Design in the discipline of Technology of Architecture and on the need to adapt the design method to the innovation of thought implemented by the research world. The theme of the Innovation in the Method of Technological Design is an interesting challenge that in this volume has been addressed considering the complexity of the levels of thematic depth, opening up to critical reflections, proposals for tools and illustration of case studies that show the breadth, relevance and multidimensionality of this issue. The era of digital and information technology have significantly influenced the way of doing and thinking in architecture and this e…
Subtropical streams harbour higher genus richness and lower abundance of insects compared to boreal streams, but scale matters
2018
Aim: Biological diversity typically varies between climatically different regions, and regions closer to the equator often support higher numbers of taxa than those closer to the poles. However, these trends have been assessed for a few organism groups, and the existing studies have rarely been based on extensive identical surveys in different climatic regions. Location: We conducted standardized surveys of wadeable streams in a boreal (western Finland) and a subtropical (south-eastern Brazil) region, sampling insects identically from 100 streams in each region and measuring the same environmental variables in both regions. Taxon: Aquatic insects. Methods: Comparisons were made at the scale…
Straw uses trade-off only after soil organic carbon steady-state
2018
Soil organic matter (SOM) is the key for a healthy soil and a relevant property to achieve the sustainability on soil management. However, soils are still net exporters of organic matter. One example is the use of wheat straw residue for industrial and energy applications, which has gained attention in the last years. The offfarm use of this abundant and low cost resource should follow sustainability criteria to avoid soil degradation and SOM losses. Straw residue incorporation is recognized as a recommended management practice to control erosion and mitigate CO2 emissions by increasing SOM. The goal of this work was: i) to evaluate the steady-state carbon (C) level in relation to C input a…
Measurement of Physical Fitness and 24/7 Physical Activity, Standing, Sedentary Behavior, and Time in Bed in Working-Age Finns : Study Protocol for F…
2022
Background: Population studies gathering measured data on fitness and physical behavior, covering physical activity, standing, sedentary behavior, and time in bed, are scarce. This article describes the protocol of the FINFIT 2021 study that measures fitness and physical behavior in a population-based sample of adults and analyzes their associations and dose–response relationships with several health indicators. Methods: The study comprises a stratified random sample of 20–69-year-old men and women (n = 16,500) from seven city-centered regions in Finland. Physical behavior is measured 24/7 by tri-axial accelerometry and analyzed with validated MAD-APE algorithms. Health and fitness examinat…
Izmaiņas Latvijas piekrastes ainavā 20.-21. gadsimta mijā un mūsdienu izaicinājumi
2013
Dažādi faktori ietekmē piekrastes zonas attīstību gan pasaulē, gan Latvijā, kā rezultātā notiek izmaiņas ainavas struktūrā un tās spējā nodrošināt sabiedrībai nepieciešamos resursus. Promocijas darbā Latvijas piekrastes ainava ir pētīta atšķirīgos mērogos un kontekstos: i) izmaiņas jūras piekrastes ainavas struktūrā un tās ietekmējošie faktori ir vērtēti visas Latvijas piekrastes zonā; ii) potenciālā vēja enerģijas ražošanas jūrā ietekme uz ainavas vizuālo struktūru ir novērtēta unikālajā Baltijas jūras stāvkrastu zonā; iii) pludmales ainavas kā rekreācijas pakalpojuma nodrošinātāja nozīmīgums ir noskaidrots četrās atšķirīgās Latvijas pludmalēs. Darbs ir transdisciplinārs, jo tajā ir izmant…
Comment positionner l'offre culturelle ? De la compréhension de la relation personne – objet à l'intégration du lieu de consommation
2005
This article seeks to answer the strategic question of the cultural institutions positioning by insisting on the need, on the one hand, for analyzing the total relation between the consumer and the cultural object (central road of positioning definition) and, on the other hand, for considering the role of the cultural place (peripheral road). We will be able to consider that the ways of differentiation are multiple and correspond to a conceptualization of the ambivalent cultural experience.
S’aimer à l’heure du numérique : la relation conjugale à l’épreuve de l’hyperconnectivité
2014
L’introduction des nouveaux objets connectés (NOC) dans les foyers vient réinterroger la relation conjugale. Avec les objets nomades, le couple doit faire face à un individualisme connecté. Ils amplifient notamment la privatisation des territoires dans l’espace domestique semblant de ce fait affecter la conversation conjugale. À travers notre enquête, nous avons constaté que les technologies de l’information et de la communication (TIC) peuvent certes avoir un impact négatif sur la relation de couple, mais peuvent a contrario venir renforcer la relation en donnant entre autres une nouvelle place à l’écrit dans la communication conjugale. Des différences apparaissent toutefois selon les type…
Associations between adolescents’ energy drink consumption frequency and several negative health indicators
2023
Abstract Background The purpose of this study was to identify how various negative health indicators are associated with energy drink consumption frequency among 13- and 15-year-old Finnish adolescents. Methods Data (N = 2429) from the nationally representative international Health Behaviour in School-aged Children study (2018) were analyzed via descriptive analysis and logistic regression analyses, with control for salient covariates. Relative risks (RR) were derived from the adjusted odds ratios. Results Even infrequent energy drink consumption was associated with various negative health indicators. Moreover, as compared to non-users, frequent energy drink consumers were more likely to re…
Evaluation of rehabilitation impact on hydraulic and environmental performance of sewer systems (WP3 CARE-S Project)
2005
The research project CARE-S (Computer Aided RE-habilitation of Sewer Networks) deals with public sewer and storm water networks of any dimension. CARE-S aims to analyse the structural and functional reliability of wastewater networks at minimum cost and disturbance. The ultimate product will be a Decision Support System (DSS) that will enable municipal engineers to establish and maintain effective management of their sewer networks. The project work plan follows a logical structure for the necessary work. It is divided in 10 Work Packages (WP) and each WP is distributed among several partners. The present paper presents the structure and the final results of WP 3 .The work package aim is th…
