Kāzas: izrāde un tās elementi
2019
Bakalaura darba nosaukums ir „Kāzas: izrāde un tās elementi”. Šī darba ietvaros veiktā pētījuma mērķis bija noskaidrot, kādi kāzu izrādes elementi mūsdienās tiek piedāvāti, lai uzvestu kāzu izrādi. Teorijas daļu veido četras nodaļas: 1.Kāzas kā pārejas rituāls sabiedrībā un ģimenē; 2.Ērvinga Gofmaņa dramaturģiskā pieeja un tās lietojums kāzu kā izrādes izpētē; 3.Kāzu izpēte socioloģijā un citās nozarēs un 4.Metodoloģija kāzu izrādes izpētē. Darbā tika izvēlētas kvalitatīvās pētniecības metodes, datu ieguves metode bija dokumentu analīze un vizuālie dati – kāzu video un kāzu fotogrāfijas, bet kā datu analīzes metode tika izvēlēta kvalitatīvā kontentanalīze. Pētījuma galvenie secinājumi ir, k…
Structure and characteristics of laser crystallized thin amorphous Si films
2011
Abstract Pure amorphous Si thin films deposited on oxidized crystalline Si surface (111) were crystallized by picosecond UV laser pulses. The Raman scattering spectra show that pulse energy of 330 mJ/cm2 is enough to fully crystallize Si film and further increase of the energy does not improve crystallinity. A large grained polycrystalline Si was obtained as revealed by surface analysis. A significant increase in carrier mobility was observed after laser crystallization.
First Nearctic Record of Hydrellia albilabris (Meigen) (Diptera: Ephydridae), a Leafminer of Duckweed (Araceae: Lemnoideae), with Comments on Related…
2019
Hydrellia albilabris (Meigen) (Diptera: Ephydridae) is recorded in the Nearctic Region for the first time. Its biology and immature stages are documented, and other miners in duckweeds (Araceae: Lemnoideae) are discussed. One new combination is proposed: Hydrellia jinpingensis (Zhang, Yang, and Hayashi) is transferred from Cavatorella.

Characterization of the nucleation process of lysozyme at physiological pH: Primary but not sole process
2013
We report on a kinetic study of the heat-induced aggregation process of lysozyme at physiological pH. The time evolution of the aggregation extent and the conformational changes of the protein were followed by dynamic light scattering (DLS) and FTIR spectroscopy, respectively, whereas the morphology of the aggregates was observed by Atomic Force Microscopy (AFM). The conformational changes of the secondary and tertiary structures were simultaneous and distinct in time with respect to the formation of aggregates. Oligomer formation occurred through at least two different aggregation processes: a nucleation process and a homogeneous non-nucleative diffusion-controlled process. FTIR measuremen…
Preparation of Biomolecule Microstructures and Microarrays by Thiol-ene Photoimmobilization
2009
A mild, fast and flexible method for photoimmobilization of biomolecules based on the light-initiated thiol-ene reaction has been developed. After investigation and optimization of various surface materials, surface chemistries and reaction parameters, microstructures and microarrays of biotin, oligonucleotides, peptides, and MUC1 tandem repeat glycopeptides were prepared with this photoimmobilization method. Furthermore, MUC1 tandem repeat glycopeptide microarrays were successfully used to probe antibodies in mouse serum obtained from vaccinated mice. Dimensions of biomolecule microstructures were shown to be freely controllable through photolithographic techniques, and features down to 5 …
Dendritic cells in liver injury and fibrosis: shortcomings and promises.
2013
SummaryThe phenotype and function of liver dendritic cells (LDCs) are poorly understood. This Snapshot summarizes our current knowledge on LDCs in the healthy and injured liver, and their role in fibrosis progression and reversal. It also draws attention to various pitfalls in the current experimental design and conclusions based on available data.
Statistical Modeling of Huffman Tables Coding
2005
An innovative algorithm for automatic generation of Huffman coding tables for semantic classes of digital images is presented. Collecting statistics over a large dataset of corresponding images, we generated Huffman tables for three images classes: landscape, portrait and document. Comparisons between the new tables and the JPEG standard coding tables, using also different quality settings, have shown the effectiveness of the proposed strategy in terms of final bit size (e.g. compression ratio).
Bis(1H-indol-2-yl)methanones are effective inhibitors of FLT3-ITD tyrosine kinase and partially overcome resistance to PKC412A in vitro.
2009
Inhibition of the mutated fms-like tyrosine kinase 3 (FLT3) receptor tyrosine kinase is a promising therapeutic strategy in acute myeloid leukaemia (AML). However, development of resistance to FLT3 tyrosine kinase inhibitors (TKI), such as PKC412A, has been described recently. This observation may have an increasing impact on the duration of response and relapse rates in upcoming clinical trials employing FLT3-TKI. Herein we investigated two representatives of a novel class of FLT3-TKI: Bis(1H-indol-2-yl)methanones. Both compounds effectively induced apoptosis in FLT3-internal tandem duplicate (ITD)-transfected murine myeloid cells and in primary FLT3-ITD positive blasts. Combination of bot…
