Elektroniskie pierādīšanas līdzekļi.
2017
Elektroniskie pierādījumi ir salīdzinoši jauns pierādījuma veids, un to izmantošanu civilprocesā nosaka tiesa likuma noteiktajā kārtībā. 21. gadsimts ir tehnoloģiju laikmets, līdz ar tehnoloģiju attīstīšanos būtiski mainās arī elektronisko pierādījumu nozīme tiesu procesos. Pierādījumu avoti mainās un attīstās ik dienu. Elektroniskos pierādījumus civilprocess pieskaita pie rakstveida pierādīšana līdzekļiem, kuri ir vieni no svarīgākajiem pierādīšanas līdzekļu veidiem civilprocesā. Rakstveida pierādījumi ikdienā tiek pielietoti dažādās dzīves jomās t.sk. gan privātajā sfēra, gan biznesa sfērā. 21.gs. ietvaros rakstiskie dokumenti tiek nomainīti uz elektroniskajiem dokumentiem, kas dod iespēj…
Control of Molecular Orbital Ordering Using a van der Waals Monolayer Ferroelectric
2022
Two-dimensional (2D) ferroelectric materials provide a promising platform for the electrical control of quantum states. In particular, due to their 2D nature, they are suitable for influencing the quantum states of deposited molecules via the proximity effect. Here, we report electrically controllable molecular states in phthalocyanine molecules adsorbed on monolayer ferroelectric material SnTe. In particular, we demonstrate that the strain and ferroelectric order in SnTe creates a transition between two distinct orbital orders in the adsorbed phthalocyanine molecules. By controlling the polarization of the ferroelectric domain using scanning tunneling microscopy (STM), we have successfully…
Controlling Exciton Propagation in Organic Crystals through Strong Coupling to Plasmonic Nanoparticle Arrays.
2022
Exciton transport in most organic materials is based on an incoherent hopping process between neighboring molecules. This process is very slow, setting a limit to the performance of organic optoelectronic devices. In this Article, we overcome the incoherent exciton transport by strongly coupling localized singlet excitations in a tetracene crystal to confined light modes in an array of plasmonic nanoparticles. We image the transport of the resulting exciton–polaritons in Fourier space at various distances from the excitation to directly probe their propagation length as a function of the exciton to photon fraction. Exciton–polaritons with an exciton fraction of 50% show a propagation length…
Time-linear scaling nonequilibrium Green's function method for real-time simulations of interacting electrons and bosons. II : Dynamics of polarons a…
2022
Nonequilibrium dynamics of the open chain Holstein-Hubbard model is studied using the linear time-scaling GKBA+ODE scheme developed in Pavlyukh et al. [Phys. Rev. B 105, 125134 (2022)]. We focus on the set of parameters relevant for photovoltaic materials, i.e., a pair of electrons interacting with phonons at the crossover between the adiabatic and antiadiabatic regimes and at moderately large electron-electron interaction. By comparing with exact solutions for two corner cases, we demonstrate the accuracy of the T matrix (in the pp channel) and the second-order Fan (GD) approximations for the treatment of electronic (e−e) and electron-phonon (e-ph) correlations, respectively. The feedback …
Surfactant-based enrichment of rare earth elements from NdFeB magnet e-waste: Optimisation of cloud formation and rare earths extraction
2023
Appropriate waste and resource management are essential for a sustainable circular economy with reduced environmental impact. With critical resources, e-waste may serve as indirect raw material. For example, with NdFeB permanent magnets, Neodymium (Nd) and the co-present Dysprosium (Dy) are critical rare earth elements (REEs). However, there exists no economically viable technology for recycling them from electronic waste (e-waste). Here, a method is presented based on cloud point extraction (CPE). The work involves basic complexation chemistry in a cloud medium with pure REE salts, as well as, with real NdFeB-magnets (nearly 28% REE content by weight) from an old hard disk drive (5.2 g mag…
“Not Only for a Celebration of Competitive Overwatch but Also for National Pride”: Sportificating the Overwatch World Cup 2016
2020
While the most popular forms of organized competitive digital gaming, also known as eSports, have begun finding their place within and in relation to both mainstream entertainment culture and the field of traditional sports, their history is one of struggling to be accepted as “true sports.” Partly because of this history, great effort has been put into the sportification of eSports by presenting competitions in familiar ways adapted from traditional sports. In this article, we examine the process of sportification of eSports in the context of tournament broadcasts. We analyze the Overwatch World Cup 2016 tournament, comparing its final broadcast to the 2014 FIFA World Cup’s final broadcast…
Pyrazolium- and 1,2-Cyclopentadiene-Based Ligands as σ-Donors: a Theoretical Study of Electronic Structure and Bonding
2012
A high-level theoretical investigation of 1,2-cyclopentadiene (4) was performed using density functional theory and wave function methods. The results reveal that, in contrast to earlier assumptions, the ground state of this ephemeral “allene” is carbene-like with a small diradical component. Furthermore, the electronic structure and chemistry of 4 are found to parallel that of 1,2,4,6-cycloheptatetraene: both molecules possess a low-lying excited singlet state with a closed-shell carbenic structure, enabling rich coordination chemistry. Energy decomposition analyses conducted for currently unknown metal complexes of 4 as well as those involving stable carbenes based on the pyrazolium frame…
Brukertilfredshet i et elektronisk pasientjournalsystem – hva påvirker brukertilfredsheten? : Hva påvirker ansatte på et sykehus i Sør–Norges brukert…
2019
Masteroppgave helse- og sosialinformatikk HSI500 - Universitetet i Agder 2019 InnledningEtter hvert som befolkningen i Norge blir eldre og sykere er det et behov for informasjon om den enkelte pasient i helsevesenet. I Norge per i dag er det ingen felles journalløsninger som dekker alle nivåer i helsevesenet. Dette fører til at de som trenger informasjon ikke alltid har den nødvendige tilgangen. Det brukes forskjellige systemer avhengig av helseforetak, sykehus, kommune og lignende. På et sykehus i Sør –Norge brukes den elektroniske pasientjournalen (EPJ) DIPS, hvor alle nyansatte får opplæring før de gis tilgang til å dokumentere i DIPS. Denne studien forsøker å belyse opplæringens betydni…
DNA-molekyylin sähkönjohtavuusmittaukset
2012
DNA-molekyylien sähkönjohtavuus on askarruttanut tutkijoita jo usean vuosikymmenen ajan. Periaatteessa DNA-molekyylin sähköiset mittaukset eivät eroa mitenkään minkä tahansa sähkökomponenttien mittauksesta. Useat tutkimukset ovat kuitenkin osoittaneet, että hyvin monet parametrit mittausjärjestelyissä vaikuttavat saatuihin tuloksiin merkittävästi, joten mitään yksiselitteistä vastausta DNA:n sähkönjohtavuuteen ei ole saatu. Tämä opinnäyte keskittyykin näissä erityyppisissä mittauksissa käytettyjen mittausjärjestelyjen tarkasteluun ja saatuihin tuloksiin. Tutkimukset jaotellaan epäsuoriin ja suoriin mittauksiin, joiden erityispiirteet pyritään selvittämään. Lisäksi mittausten tuloksia pyritä…
