Darbs ar tekstilmateriāliem dizainā un tehnoloģijās 3.klasē
2022
Diplomdarba “Darbs ar tekstilmateriāliem dizainā un tehnoloģijās 3.klasē” mērķis izstrādāt mācību saturu tēmai “Darbs ar tekstilmateriāliem dizainā un tehnoloģijās 3.klasē” un aprobēt praksē. Pētījums sastāv no trim nodaļām. Pirmajā sniegts teorētiskais pamatojums mācību satura veidošanai dizainā un tehnoloģijās, īpaši akcentēta tēma “Darbs ar tekstilmateriāliem”, kuras ietvaros apkopota informācija par vilnu un tās ieguvi, kas ļauj veidot integrētu mācību saturu, kā arī par filcēšanu un izšūšanu. Otrajā nodaļā sniegts pārskats par izstrādāto tematisko plānu tēmas “Darbs ar tekstilmateriāliem” ietvaros, bet trešajā – pārskats par veikto aprobāciju. Noslēgumā formulēta atbilde uz pētījuma ja…

A randomized controlled trial protocol for persistent physical symptoms associated with indoor environment or chronic fatigue : Effectiveness of vide…
2023
IntroductionPersistent physical symptoms (PPS) refer to symptoms that cannot be fully explained by structural bodily pathology or by environmental factors. Their impact on daily functioning varies from mild to severe disability. So far, evidence-based treatments for PPS have resulted in only small to moderate effects. Treatment protocols with a stronger orientation toward personalized approaches are needed to improve the efficacy and applicability of treatment. In this study, we aim to assess the effect of an online individual case conceptualization with web-based program for PPS. This study is conducted among two focus groups: patients with indoor air-related symptoms and patients with chr…
Labor as Action: the Human Condition in the Anthropocene
2020
Abstract The Anthropocene has become an umbrella term for the disastrous transgression of ecological safety boundaries by human societies. The impact of this new reality is yet to be fully registered by political theorists. In an attempt to recalibrate the categories of political thought, this article brings Hannah Arendt’s framework of The Human Condition (labor, work, action) into the gravitational pull of the Anthropocene and current knowledge about the Earth System. It elaborates the historical emergence of our capacity to “act in the mode of laboring” during fossil-fueled capitalist modernity, a form of agency relating to our collectively organized laboring processes reminiscent of the…
Thermoelectric radiation detector based on a superconductor-ferromagnet junction : Calorimetric regime
2018
We study the use of a thermoelectric junction as a thermal radiation detector in the calorimetric regime, where single radiation bursts can be separated in time domain. We focus especially on the case of a large thermoelectric figure of merit $ZT$ affecting significantly for example the relevant thermal time scales. This work is motivated by the use of hybrid superconductor/ferromagnet systems in creating an unprecedentedly high low-temperature $ZT$ even exceeding unity. Besides constructing a very general noise model which takes into account cross correlations between charge and heat noise, we show how the detector signal can be efficiently multiplexed by the use of resonant LC circuits gi…
Hypersensitive tunable Josephson escape sensor for gigahertz astronomy
2020
Sensitive photon detection in the gigahertz band constitutes the cornerstone to study different phenomena in astronomy, such as radio burst sources, galaxy formation, cosmic microwave background, axions, comets, gigahertz-peaked spectrum radio sources and supermassive black holes. Nowadays, state of the art detectors for astrophysics are mainly based on transition edge sensors and kinetic inductance detectors. Overall, most sensible nanobolometers so far are superconducting detectors showing a noise equivalent power (NEP) as low as 2x10-20 W/Hz1/2. Yet, fast thermometry at the nanoscale was demonstrated as well with Josephson junctions through switching current measurements. In general, det…

Cosmic-ray muon flux at Canfranc Underground Laboratory
2019
Residual flux and angular distribution of high-energy cosmic muons have been measured in two underground locations at the Canfranc Underground Laboratory (LSC) using a dedicated Muon Monitor. The instrument consists of three layers of fast scintillation detector modules operating as 352 independent pixels. The monitor has flux-defining area of 1 m${}^{2}$, covers all azimuth angles, and zenith angles up to $80^\circ$. The measured integrated muon flux is $(5.26 \pm 0.21) \times 10^{-3}$ m${}^{-2}$s${}^{-1}$ in the Hall A of the LAB2400 and $(4.29 \pm 0.17) \times 10^{-3}$ m${}^{-2}$s${}^{-1}$ in LAB2500. The angular dependence is consistent with the known profile and rock density of the sur…

A 4 tonne demonstrator for large-scale dual-phase liquid argon time projection chambers
2018
A 10 kilo-tonne dual-phase liquid argon TPC is one of the detector options considered for the Deep Underground Neutrino Experiment (DUNE). The detector technology relies on amplification of the ionisation charge in ultra-pure argon vapour and offers several advantages compared to the traditional single-phase liquid argon TPCs. A 4.2 tonne dual-phase liquid argon TPC prototype, the largest of its kind, with an active volume of \three has been constructed and operated at CERN. In this paper we describe in detail the experimental setup and detector components as well as report on the operation experience. We also present the first results on the achieved charge amplification, prompt scintillat…
