Jaunas rīcībpolitikas izveide: bezpilota lidaparātu (dronu) izmantošanas gadījums
2018
Bakalaura darba “Jaunas rīcībpolitikas izveide: bezpilota lidaparātu (dronu) izmantošanas gadījums” galvenie mērķi ir identificēt veidus, kā Latvija varētu izmantot bezpilota lidaparātu (dronu) tehnoloģiju publiskajā sektorā, un izveidot dronu izmantošanas rīcībpolitikas uzmetumu. Lai šos veidus noteiktu un iegūto informāciju izmantotu rīcībpolitikas uzmetuma veidošanā, tika veikta rīcībpolitikas pārvietošanas analīze, kuras ietvaros tika analizēta Amerikas Savienoto Valstu (ASV) pieredze bezpilota lidaparātu tehnoloģijas izmantošanā publiskajā sektorā. Pētījums ir konstruēts divās daļās – teorētiskajā un empīriskajā. Teorētiskajā daļā ir aprakstīta rīcībpolitikas pārvietošanas teorija un s…
Positron production using a 9 MeV electron linac for the GBAR experiment
2020
For the GBAR (Gravitational Behaviour of Antihydrogen at Rest) experiment at CERN's Antiproton Decelerator (AD) facility we have constructed a source of slow positrons, which uses a low-energy electron linear accelerator (linac). The driver linac produces electrons of 9 MeV kinetic energy that create positrons from bremsstrahlung-induced pair production. Staying below 10 MeV ensures no persistent radioactive activation in the target zone and that the radiation level outside the biological shield is safe for public access. An annealed tungsten-mesh assembly placed directly behind the target acts as a positron moderator. The system produces $5\times10^7$ slow positrons per second, a performan…
Bisfosfonaatit : valmistus, ominaisuudet ja lääketieteellinen käyttö
2016
Tutkielman kirjallisessa osassa perehdytään bisfosfonaatteihin, niiden ominaisuuksiin ja valmistukseen sekä käyttöön lääketieteessä. Bisfosfonaattien valmistuksessa perehdytään sekä itse bisfosfonaattien että niiden johdannaisten valmistukseen. Bisfosfonaattien ominaisuuksia käydään läpi esittämällä niiden kemiallisia, biokemiallisia sekä farmakologisia ominaisuuksia ja vaikutustapoja. Eri bisfosfonaattien ominaisuuksia käsittelevät kappaleet on jaoteltu niistä käytettävän sukupolvijaottelun mukaisesti. Bisfosfonaattien käytössä pääosassa ovat niiden lääketieteelliset sovellukset. Bisfosfonaattien aihiolääkkeiden valmistuksessa keskitytään happoryhmän esteröintiin, amino- tai hydroksyyliryh…
The use of very high resolution images for studying Posidonia oceanica reefs
2020
Posidonia oceanica is an endemic Mediterranean seagrass that forms wide and dense meadows from the surface up to about 40 m depth. This species can develop a biogenic structure called matte, a typical terraced formation built up by itself, consisting of intertwined rhizomes, roots and sediment, which may allow shoots to reach the sea surface forming reefs (récif barrière), considered natural monuments. Posidonia oceanica reefs are particularly exposed to the ongoing increase in temperature and in storm frequency and intensity due to climate change, with negative repercussions on their conservation. Much more attention must be paid to the implementation of monitoring tools able to detect ear…
Charged jet cross sections and properties in proton-proton collisions at $\sqrt{s}=7$ TeV
2015
The differential charged jet cross sections, jet fragmentation distributions, and jet shapes are measured in minimum bias proton-proton collisions at centre-of-mass energy $\sqrt{s}=7$ TeV using the ALICE detector at the LHC. Jets are reconstructed from charged particle momenta in the mid-rapidity region using the sequential recombination $k_{\rm T}$ and anti-$k_{\rm T}$ as well as the SISCone jet finding algorithms with several resolution parameters in the range $R=0.2$ to $0.6$. Differential jet production cross sections measured with the three jet finders are in agreement in the transverse momentum ($p_{\rm T}$) interval $20<p_{\rm T}^{\rm jet,ch}<100$ GeV/$c$. They are also consistent w…
Predicted gamma-ray image of SN 1006 due to inverse Compton emission
2009
We propose a method to synthesize the inverse Compton (IC) gamma-ray image of a supernova remnant starting from the radio (or hard X-ray) map and using results of the spatially resolved X-ray spectral analysis. The method is successfully applied to SN 1006. We found that synthesized IC gamma-ray images of SN 1006 show morphology in nice agreement with that reported by the H.E.S.S. collaboration. The good correlation found between the observed very-high energy gamma-ray and X-ray/radio appearance can be considered as an evidence that the gamma-ray emission of SN 1006 observed by H.E.S.S. is leptonic in origin, though the hadronic origin may not be excluded.
