Some decisional problems on rational relations

1997

Abstract In this paper we prove that the problem of deciding whether a deterministic rational relation is star-free is recursively solvable, although the same problem for any rational relation is undecidable. We also prove that a rational relation is star-free if and only if it is aperiodic and deterministic.

An inconvenient influence of iridium(III) isomer on OLED efficiency.

2010

The recently reported heteroleptic cyclometallated iridium(III) complex [Ir(2-phenylpyridine)(2)(2-carboxy-4-dimethylaminopyridine)] N984 and its isomer N984b have been studied more in detail. While photo- and electrochemical properties are very similar, DFT/TDDFT calculations show that the two isomers have different HOMO orbital characteristics. As a consequence, solution processed OLEDs made using a mixture of N984 and isomer N984b similar to vacuum processed devices show that the isomer has a dramatic detrimental effect on the performances of the device. In addition, commonly used thermogravimetric analysis is not suitable for showing the isomerization process. The isomer could impact pe…

Detoxifying antitumoral drugs via nanoconjugation: the case of gold nanoparticles and cisplatin

2021

Nanoparticles (NPs) have emerged as a potential tool to improve cancer treatment. Among the proposed uses in imaging and therapy, their use as a drug delivery scaffold has been extensively highlighted. However, there are still some controversial points which need a deeper understanding before clinical application can occur. Here the use of gold nanoparticles (AuNPs) to detoxify the antitumoral agent cisplatin, linked to a nanoparticle via a pH-sensitive coordination bond for endosomal release, is presented. The NP conjugate design has important effects on pharmacokinetics, conjugate evolution and biodistribution and results in an absence of observed toxicity. Besides, AuNPs present unique o…

Uptake of chlorohydrocarbons from soil by lipid-containing semipermeable membrane devices (SPMDs)

1998

Chlorohydrocarbons (CHCs) were surveyed in contaminated lake shore soil in Central Finland with polyethylene membranes containing synthetic triolein (SPMDs). High levels of hexachlorobenzene (HCBz) and PCBs were found in a significant number of the SPMDs exposed 28 days to 35 soil sampling locations along the 350 meter long shoreline. Distributions of HCBz and PCBs were different as demonstrated by two maximas of HCBz and four maximas of PCBs observed. Soil was also analyzed at selected locations for concentrations of CHCs, organic carbon (OC) and moisture. Steady state environmental fate modeling and simple equilibrium partition estimates based on analytical results both gave the same stea…

Embedding the Remote Application Control: Visual API for PDA Programming

2009

PDAs are more and more used as advanced adaptive HEI (human-environment interaction) interfaces, thus enabling their users to easily operate applications remotely running in pervasive computing scenarios. Based on a previous implementation, in this paper we discuss the development of a new set of .NET-compliant Application Programming Interfaces to be used within the Visual Studio IDE. Our main goal is to provide programmers with a set of components to be used with the common drag-and-drop operation, in order to embed a remote application control within an application running on the PDA and vice-versa. The interaction relies on ad-hoc communication protocols over a framework devoted to pair…

Leksiski stilistiskie līdzekļi Dž. R.R. Tolkīna garastāstā Kalējs no Lielās Vutonas

2017

Šajā darbā tiek pētīti leksiskie stilistiskie valodas izteiksmes līdzekļi Dž.R.R Tolkīna fantāzijas novelē Kalējs no Lielās Vutonas. Tolkīnam bija unikāls rakstīšanas stils, kurā galveno lomu spēlēja iztēle un alegoriska valoda, jo viņš uzskatīja, ka mītu vai pasakas būtību var pārnest izmantojot tikai šadu valodu. Kalējs no Lielas Vutonas bija Tolkīna pedējais literārais darbs, kurš tika izdots viņa dzīves laikā, un tajā bija daudz alegorieski tēli, kuri pēc pētnieku domām atspoguļoja Tolkīnas dzīvi. Šis pētijums tika veikts, lai noteiktu leksiski stilistisko līdzekļu nozīmi un funkciju izvēlēta fantāzijas novelē. Ar teksta analīzes metodes palīdzību tika noteikti un analizēti leksiski sti…

Tēlainas valodas elementi TED prezentācijās

2020

Šī bakalaura darba mērķis bija atklāt, kāds ir iemesls, kāpēc epiteti, metaforas un hiperbolas tiek izmantotas TED prezentācijās, kas tālāk iedalās kādu epitetu un metaforu veidi tika izmantoti šajās prezentācijās, un atklāt, kad šie trīs specifiskie tēlainas valodas elementi tiek izmantoti. Izpētot šī pētījuma teorētisko daļu, kas sastāvēja no vairāku autoru sniegtajām definīcijām, tika secināts, ka šie trīs tēlainas valodas elementi publiskajās runās veic ievērojamu lomu, pievienojot tēlainību, vērš uzmanību un izplata informāciju. Un pēc daudzu TED prezentāciju videoierakstu novērošanas, divdesmit no tām tika izvēlētas tālākai izmeklēšanai, kur kļuva skaidrs, ka visi no tiem ietver vairā…

Varoņu attēlojuma analīze spēlē “Leģendu līga”

2022

Šajā pētījumā analizēti trīs reģionu apraksti un attiecīgo čempionu biogrāfijas, kas atrodami Leģendu Līgas stāstā. Pašlaik esošie pētījumi par spēļu varoņiem pētījums ir saistīti ar varoņu dzimumu vai citiem aspektiem. Pētījuma mērķis bija noskaidrot rakstura īpašības, kas veicina rakstura atveidi, un noteikt, kādi izteiksmes līdzekļi tiek izmantoti, lai šīs īpašības uzsvērtu stāstā. Pētījuma jautājums bija vērsts uz čempiona piederības noteikšanu konkrētajam reģionam pēc attiecīgajām īpašībām. Pētījums veikts, izmantojot tematisko analīzi. Rezultāti atklāja, ka čempioni galvenokārt tika attēloti pēc kognitīvajām īpašībām. Rakstura īpašību aspektu paspilgtināšanai vai pastiprināšanai visva…
