Mediju politiskās dienaskārtības noteikšanas vara: Saeimas deputātu viedokļi (2017. gads)

2017

Maģistra darba mērķis ir noskaidrot 12.Saeimas deputātu viedokļus par nacionālo mediju varu nacionālā līmeņa politiskās dienaskārtības notiekšanas procesā. Parlamenta deputātu viedokļu pētījumos Zviedrijā un Beļģijā tika secināts, ka masu mediji ir vieni no ietekmīgākajiem politiskās dienaskārtības noteicējiem līdzās premjerministram un politiskajām partijām. Iedvesmojoties no iepriekšējos pētījumos paustajām atziņām, tika īstenots Saeimas deputātu pētījums, atklājot parlamentāriešu viedokļus par masu mediju varu uz nacionālā līmeņa dienaskārtības noteikšanu. Pētījums balstīts politiskās komunikācijas, dienaskārtības noteikšanas un politikas mediatizācijas literatūras analizē. Pētījuma uzde…

A new copper(II) chelate complex with polyamines as fire retardant and epoxy hardener: Synthesis, crystal and electronic structure, and thermal behav…

2020

A new (ethylenediamine-N,N′)-(diethylenetriamine-N,N′,N″)-copper(II) hexafluoridosilicate complex, [Cu(eda)(deta)]SiF6 (1) (eda – ethylenediamine; deta – diethylenetriamine), was synthesized by direct interaction of anhydrous CuSiF6 with polyethylenepolyamine (pepa – H2N[C2H4NH]nH, where n = 1 (eda) and 2 (deta)). The crystals of 1 were characterized by IR spectroscopy and X-ray diffraction. Compound 1 consists of SiF62− discrete anions and [Cu(eda)(deta)]2+ complex cations whose Cu2+ ions are chelated by eda and deta. The coordination polyhedron of Cu(II) atom is an elongated square pyramid which consists of four nitrogen atoms belonging to NH2 groups of eda and NH2 and NH groups of …

Dynamics of Strongly Coupled Modes between Surface Plasmon Polaritons and Photoactive Molecules: The Effect of the Stokes Shift

2017

We have investigated the dynamics of strongly coupled modes of surface plasmon polaritons (SPPs) and fluorescent molecules by analyzing their scattered emission polarization. While the scattered emission of SPPs is purely transverse magnetic (TM) polarized, the strong coupling with molecules induces transverse electric (TE) polarized emission via the partial molecular nature of the formed SPP–molecule polariton mode. We observe that the TM/TE ratio of the polariton emission follows the contribution of the molecular excited states in this hybrid mode. By using several types of molecules, we observe that, in addition to the coupling strength, which determines the contribution of the molecular…

Intervālās badošānās efekti uz ķermeņa audu kompozīciju un asins plazmas bioķīmiskiem parametriem

2020

Intervālās badošanās uztura režīms ir relatīvi jauna pieeja svara samazināšanai lai uzlabotu ķermeņa audu kompozīciju un vispārējo veselību. Intervālās badošanās diētās pamatā ir kaloriju uzņemšanas periodu kontrole, nevis kaloriju daudzums. Šajā pētījumā tika salīdzināti divi intervālās badošanās diētu modeļi - laikā ierobežoto un noteikto dienu badošanās modeļi. Tika novērtēta iepriekšminēto modeļu ietekme uz antropometriskiem parametriem, ķermeņa audu kompozīciju un asins plazmas bioķīmisko parametru izmaiņām pirms un pēc uztura režīma ievērošanas. Šim nolūkam tika izmantota kaliperēšanas metode, lai noteiktu relatīvo tauku masu, un ultrasonogrāfijas metode, vairāku taukaudu slāņu biezum…

APPROCCIO MINIMAMENTE INVASIVO ALLA NEFRECTOMIA DA DONATORE VIVENTE A SCOPO DI TRAPIANTO: TECNICHE LESS E NOTES

Il trapianto di rene è al momento il miglior trattamento per i pazienti affetti da IRC terminale. Il costante e graduale aumento del numero dei pazienti che necessitano di tale tipo di trattamento, e la crescente carenza di donatori cadavere, hanno reso necessario lo sviluppo di strategie volte ad allargare ed ottimizzare il pool dei donatori impiegando, a scopo di trapianto, reni provenienti da donatori viventi. Il trapianto renale da vivente rappresenta in quest’ottica la carta vincente, in grado di ridurre i tempi di attesa; è stato anche dimostrato che si hanno risultati migliori rispetto al trapianto di rene da donatore cadavere in quanto vi è una maggiore compatibilità genetica tra do…

Kinetic Solutions for Responsive and Communicative Building Skin

2018

Theskinof buildings represents the first level of communication between construction, man and environment. In this relationship, the concept of communication acquires different values, because it can be applied both to the architectural field in relation to the shape, and to the perceptive and communicative sphere, aimed to transmission of messages or even to the interaction of the architectural envelope with the user and the environment. This brings us back to the energy and sustainability aspects, since the primary role as a separation and filter layer of the building façades is that of shielding. The solution with a kinetic façade constitutes not only a possibility of climatic mediation …

Nanotechnology to clean up oceans. An Educational Innovation Project for the inclusion of Sustainable Development Goal SDG 14 in Secondary and Higher…

2019

Los vertidos de petróleo en el mar suponen un problema ambiental muy importante. La enorme tarea de la limpieza de éstos en mares y océanos ha pesado sobre la industria, las instituciones gubernamentales y los ecologistas desde hace décadas. El proceso de limpieza siempre ha sido dificultoso e implica grandes cantidades económicas, de recursos y de tiempo. Retirar el petróleo del agua es una tarea ardua y, a menudo, la limpieza solo se consigue de manera parcial. Sin embargo, hoy en día, los científicos han desarrollado una técnica que combina nanotecnología y magnetismo que puede ayudar a la solución de este problema. En particular, un equipo de investigadores del Instituto Tecnológico de …
