Design optimization for the quench protection of DTT's superconducting toroidal field magnets
2021
Abstract The paper is focused on the optimal design of Fast Discharge Unit (FDU) for the quench protection of the Toroidal Field (TF) magnets of the Divertor Tokamak Test facility (DTT), an experimental facility under construction in ENEA Frascati Research Centre (Rome, Italy). The FDU is a safety key component that protects the superconducting magnets when a quench is detected through the fast extraction of the energy stored in the magnets by adding a discharge dump resistor (DR) in the TF magnets circuit. A comparison between a fixed DR and a switched variable DR has been implemented by changing resistor parameters and by using multiple current control of the power electronics components …
Subventricular zone neural progenitors protect striatal neurons from glutamatergic excitotoxicity.
2012
The functional significance of adult neural stem and progenitor cells in hippocampal-dependent learning and memory has been well documented. Although adult neural stem and progenitor cells in the subventricular zone are known to migrate to, maintain and reorganize the olfactory bulb, it is less clear whether they are functionally required for other processes. Using a conditional transgenic mouse model, selective ablation of adult neural stem and progenitor cells in the subventricular zone induced a dramatic increase in morbidity and mortality of central nervous system disorders characterized by excitotoxicity-induced cell death accompanied by reactive inflammation, such as 4-aminopyridine-i…
Anandamide inhibits IL-12p40 production by acting on the promoter repressor element GA-12: Possible involvement of the COX-2 metabolite prostamide E 2
2007
The eCB [endoCB (cannabinoid)] system is being considered as a novel therapeutic target for immune disorders. Cytokines of the IL-12 (interleukin-12) family have essential functions in cell-mediated immunity. In the present study, we have addressed the mechanisms of action of the eCB AEA (anandamide) on the regulation of IL-12p40 in activated microglia/macrophages. We demonstrated that AEA can inhibit the expression of p35, p19 and p40 subunits, which form the biologically-active cytokines IL-12 and IL-23 in microglia stimulated with LPS (lipopolysaccharide)/IFNγ (interferon γ). Additionally, we have provided evidence that AEA reduces the transcriptional activity of the IL-12p40 gene in LPS…
Interaction of a Liquid Gallium Jet with ISTTOK Edge Plasmas
2008
The use of liquid metals as plasma facing components in tokamaks has recently experienced a renewed interest stimulated by their advantages in the development of a fusion reactor. Liquid metals have been proposed to solve problems related to the erosion and neutronic activation of solid walls submitted to high power loads allowing an efficient heat exhaust from fusion devices. Presently the most promising candidate materials are lithium and gallium. However, lithium has a short liquid state range when compared, for example, with gallium that has essentially better thermal properties and lower vapor pressure. To explore further these properties, ISTTOK tokamak is being used to test the inter…
Gravitational flow of a thin film of liquid metal in a strong magnetic field
2014
Abstract The influence of a poloidal magnetic field of the spherical Tokamak on super thin (h ≈ 0.1 mm) film flow of liquid metal driven by gravity over the surface of the cooled divertor plate is addressed. The experimental setup developed at the Institute of Physics, University of Latvia (IPUL) is described, which makes it possible to drive and visualize such liquid metal flows in the solenoid of the superconducting magnet “Magdalena”. As applied to the above setup, the magnetic field effect on the operation of the capillary system of liquid metal flow distribution (CSFD) is evaluated by using molten metal (lithium or eutectic InGaSn alloy) with a very small linear flowrate q ≤ 1 mm2/s, s…
Chaoskampf in the orthodox baptism ritual
2018
The present article analyses the occurrence of the Chaoskampf motif in the Orthodox Baptism ritual and its biblical and Near-Eastern backgrounds. Such statements are direct references to Old and New Testament texts in which water has negative connotations, being associated with hostile or chaotic aspects of existence. In the baptismal interpretation of the biblical motif, sea, depths and dragons are figurative names for demons. The liturgical reinterpretation of these biblical references is the preamble of the baptismal exorcisms. Biblical texts about the struggle against chaos were included in the ritual in order to illustrate Christ's supremacy over all hostile forces subduing man before …
Utopiju un antiutopiju iezīmes Luisas Lorijas Romānā “Devējs”
2016
Pašreizējais darbs ir veltīts Luisas Lorijas romāna Devējs analīzei. Pētījuma mērķis ir uzzināt kāda ir literāro utopiju un antiutopiju izcelsme un to attīstība, kādas raksturīgās iezīmes ir atrodamas ievērojamu utopiju un antiutopiju autoru darbos, un, lai atklātu kuras iezīmes Lorijas darbam ir kopīgas ar Tomasa Mora, Tommazo Kampanellas un citu utopiju un antiutopiju autoru darbiem. Pētījumā tiek izmantotas satura analīzes, uzmanīga lasījuma, un interpretācijas metodes. Galvenie rezultāti parāda, ka ideja par utopisku vietu pastāv jau vairākus gadsimtus, un, ka antiutopiskā literatūra parādījās kā atbilde uz cilvēces neveiksmīgajiem mēģinājumiem radīt reālas utopiskas kopienas. Tika izda…
Riddere på slakk line : Om pårørende, uhelbredelig kreft og komplementær og alternativ behandling
2014
Masteroppgave Universitetet i Agder, 2014 Fakultet for helse- og idrettsvitenskap Institutt for helse- og sykepleievitenskap Forskning viser at KAM-bruk er utbredt blant kreftpasienter, og pasienter med uhelbredelig kreft oppsøker i større grad KAM-behandlere. Pårørende er sentral i støtte og omsorg for pasienten, og opplever byrder og belastning i denne rollen. Hensikten med denne masteroppgaven har vært å bidra til økt kunnskap om pårørendes opplevelser, for videre kunne gi dem bedre støtte og hjelp. Problemstillingen i dette prosjektet lyder: Hvordan oppleves det å være pårørende til personer med uhelbredelig kreft som søker komplementær og alternativ behandling? Empiriske data er hentet…
Pacientu, farmaceitu un farmaceita asistentu vērtējums par Ministru Kabineta noteikumu Nr. 899 grozījumiem par valsts kompensējamo medikamentu apmaks…
2022
Šī gada 1. aprīlī aprit divi gadi kopš Ministru kabineta noteikumu Nr. 899 “Ambulatorajai ārstēšanai paredzēto zāļu un medicīnisko ierīču iegādes izdevumu kompensācijas kārtība” grozījumi stājās spēkā, kas mainīja kompensējamo medikamentu izrakstīšanas un izsniegšanas kārtību. Darba aktualitāti nosaka problēmas un grūtības pēc MK noteikumu Nr. 899 grozījumiem 2020. gada 1. aprīlī, ar kurām vēl joprojām ikdienas darbā saskaras Latvijas farmaceiti un farmaceita asistenti, kā arī Latvijas iedzīvotāji, kuri lieto valsts kompensējamos medikamentus. Darba rezultātā autore secināja, ka Latvijā ieviestā zāļu kompensācijas sistēma ir līdzīga ES valstīs esošām sistēmām, taču ir atšķirības, kuras Igau…
Speciālistu un pacientu viedoklis un problēmas saistībā ar grozījumiem Ministru kabineta noteikumos Nr.899 par zāļu vispārīgā nosaukuma izrakstīšanu
2021
2020. gada 1. aprīlī tika mainīta Latvijas valsts kompensējamo zāļu izrakstīšanas kārtība,kuru regulē MK noteikumi Nr.899 – ārsts receptē norāda aktīvo vielu, nevis konkrētu medikamenta nosaukumu, aptiekas no vienādas iedarbības un devas zālēm izsniedz kompensējamās zāles par zemāko (references) cenu. Darba aktualitāti nosaka ar MK noteikumu grozījumiem saistītās problēmsituācijas farmaceitu darbā un klientu apmierinātībā. Pētījuma mērķis: noskaidrot Latvijas farmācijas speciālistu un iedzīvotāju viedokli par MK noteikumu grozījumiem. Tika veikta respondentu anketēšana. Darba rezultātā tika secināts: farmācijas speciālistu darba ikdiena ir kļuvusi sarežģītāka. References medikamentu biežā m…
