Galvinieka atbildības problemātiskie aspekti.
2018
Bakalaura darba tēmas nosaukums ir „Galvinieka atbildības problemātiskie aspekti”. Galvojums ir viens no saistību pastiprināšanas veidiem. Lai attīstītu ekonomisko aktivitāti, jau senajā Romā, galvojums kalpoja, kā personisks garants saistību izpildīšanai. To nodrošināja trešā persona, kura ar savu galvu galvoja kreditoram par citas personas parādu. Zinātniskā darba mērķis ir izpētīt galvinieka tiesības un pienākumus fiziskas maksātnespējas procesos, normatīvo regulējumu, saistību dzēšanu, pastāvošo tiesu praksi un tiesībzinātnieku viedokļus, izzināt iespējamos strīdīgos jautājumus pastāvošajās normās un tiesu spriedumos. Lai sasniegtu darba mērķi ir noteikti sekojoši uzdevumi: 1)izpētīt ga…

A new set of standards for in–situ measurement of bromine abundances in natural silicate glasses: Application to SR-XRF, LA-ICP-MS and SIMS techniques
2017
Measuring the low bromine abundances in Earth's materials remains an important challenge in order to constrain the geodynamical cycle of this element. Suitable standard materials are therefore required to establish reliable analytical methods to quantify Br abundances. In this study we characterise 21 Br-doped glasses synthesized from natural volcanic rocks of mafic to silicic compositions, in order to produce a new set of standards for Br analyses using various techniques. The nominal Br contents (amounts of Br loaded in the experimental samples) of 15 of 21 glasses were confirmed within 20% by instrumental neutron activation analysis (INAA). Using this new set of standards, we compare thr…
Spin Crossover and Long-Lived Excited States in a Reduced Molecular Ruby.
2020
Abstract The chromium(III) complex [CrIII(ddpd)2]3+ (molecular ruby; ddpd=N,N′‐dimethyl‐N,N′‐dipyridine‐2‐yl‐pyridine‐2,6‐diamine) is reduced to the genuine chromium(II) complex [CrII(ddpd)2]2+ with d4 electron configuration. This reduced molecular ruby represents one of the very few chromium(II) complexes showing spin crossover (SCO). The reversible SCO is gradual with T 1/2 around room temperature. The low‐spin and high‐spin chromium(II) isomers exhibit distinct spectroscopic and structural properties (UV/Vis/NIR, IR, EPR spectroscopies, single‐crystal XRD). Excitation of [CrII(ddpd)2]2+ with UV light at 20 and 290 K generates electronically excited states with microsecond lifetimes. This…

<title>Electrochromism of W-oxide-based films: some theoretical and experimental results</title>
1995
We survey some recent work related to electrochromic W-oxide-based thin films. The electronic structure of cubic (perovskite) WO3 and HWO3 was calculated from first principles. It was found, among other things, that hydroxide formation was energetically favored. Experimental studies were made on films prepared by reactive magnetron sputtering in Ar + O2 with and without CF4 addition and substrate bias. Structural studies by atomic force microscopy, x-ray diffraction, infrared reflectance spectroscopy, and Raman spectroscopy indicated that the electron bombardment associated with a positive substrate bias led to grain growth and partial crystallization while maintaining a high density of W e…

Genetic relationship between clinical and environmental Vibrio cholerae isolates in Tanzania: A comparison using repetitive extragenic palindromic (R…
2015
The bacterium causing cholera, Vibrio cholerae, is a marine organism and coastal waters are important reservoirs of the organism. There are more than 200 serogroups of V. cholerae, of which serogroups O1 and O139 are known to be the causative agent of the cholera. The main virulent factor in V. cholerae is cholera toxin gene (ctx) that is found from the epidemic O1 and O139 strains, but may also be found in some strains other than O1 and O139 (non-O1 and non-O139). In this study, 48 V. cholerae strains isolated from three estuaries of Tanzania and 20 stool isolates were characterized in terms of their serogroups and possession of ctx gene and then compared using two PCR based fingerprinting…
Diseño, síntesis y caracterización de materiales moleculares multifuncionales conmutables
2019
Este trabajo de Tesis Doctoral recoge la síntesis y caracterización de una nueva generación de materiales moleculares conmutables que presentan el fenómeno de transición de espín (spin crossover, SCO). El objetivo principal de esta Tesis Doctoral se ha centrado en el diseño racional de nuevos materiales multifuncionales de Fe(II) para el desarrollo de nuevas plataformas moleculares biestables que permitan el estudio detallado del comportamiento SCO sincronizado con nuevas propiedades físico-químicas, como pueden ser la química huésped-anfitrión, transiciones de fase sólido-líquido, dopaje químico,… La estrecha interrelación entre el fenómeno SCO y la segunda propiedad ha sido monitorizada, …
