Dzimtes reprezentācija Marvel filmās
2022
Bakalaura darba “Dzimtes reprezentācija Marvel filmās” mērķis ir izpētīt kā tiek reprezentēti dzimumi, kādas ir reprezentācijas atšķirības un kādi stereotipi tiek izmantoti. Pētījuma problēma ir – lai arī kino industrija ir spērusi soļus dzimumu vienlīdzības virzienā, nav iespējams ignorēt realitāti, kādiem stereotipiem joprojām tiek pakļauti dzimumi. Ņemot vērā to, ka Marvel Cinematic Universe (MCU) ir viens no masu kultūras gigantiem, tam ir spēcīga ietekme uz sabiedrību. Teorijas daļā tiek aplūkotas tādas tēmas kā reprezentācija, kino valoda, dzimte un dzimums. Metodoloģiskajā daļā apskatītas divas kvalitatīvās pētniecības metodes kā semiotikas analīze un naratīva analīze. Empīriskajā da…
Cicha noc, święta noc
2022
Jezus Chrystus jest niewątpliwie postacią historyczną. Jednak o samym Jego narodzeniu wiemy niewiele. Opis tego wydarzenia i to w bardzo oszczędnej formie podają bowiem jedynie dwie Ewangelie. Podstaw wielu tradycji i legend związanych z Bożym Narodzeniem należy zatem szukać przede wszystkim w ewangeliach apokryficznych oraz wizjach i objawieniach mistykowi świętych. Niniejszy tekst jest zatem jedynie próbą ludzkiego spojrzenia na te najbardziej niezwykłe narodziny w dziejach.
Neatbildētības nobīdes novērošana un datu vākšanas stratēģijas optimizēšana adaptīva izlases apsekojuma gadījumā
2021
Izlases veida apsekojumos pamatā ir teorētiskā bāze, kas nosaka respondentu saraksta veidošanas, aptaujas, apstrādes likumus, kuri realizācijas laikā reālajā pasaulē saskaras ar neatbildētību, dažādiem ierobežojumiem vai datu apstrādes īpatnībām, kopumā veidojot pamatojumu pieaugošai interesei par aptaujas plānojuma pielāgošanas iespējam. Apsekojuma elastīgo organizēšanu datu vākšanas laikā, izmantojot papildus informāciju un reaģējot uz noteikto mērķu sasniegšanu, sauc par adaptīvo plānojumu. Šajā darbā tiek apskatīta vākšanas stratēģijas plānojuma veidošana īstermiņa statistikas apsekojumam, izmantojot R-indikatorus - reprezentativitātes mērus, kas parāda atšķirības pakāpi starp atbildēju…

Halogen bonding stabilizes a cis-azobenzene derivative in the solid state : A crystallographic study
2017
Crystals oftrans- andcis-isomers of a fluorinated azobenzene derivative have been prepared and characterized by single-crystal X-ray diffraction. The presence of F atoms on the aromatic core of the azobenzene increases the lifetime of the metastablecis-isomer, allowing single crystals of thecis-azobenzene to be grown. Structural analysis on thecis-azobenzene, complemented with density functional theory calculations, highlights the active role of the halogen-bond contact (N...I synthon) in promoting the stabilization of thecis-isomer. The presence of a long aliphatic chain on the azobenzene unit induces a phase segregation that stabilizes the molecular arrangement for both thetrans- andcis-i…
How important is roaming in the photodegradation of nitrobenzene?
2020
At low excitation energies nitrobenzene photoreleases NO with low translational and rotational energy, while at higher excitation energies NO is photoreleased with both low and high translational and rotational energy. The fast products are formed through a singlet-triplet crossing (STC) region featuring an oxaziridine ring, while a ground state roaming mechanism was suggested to produce the slow molecules. Computing translational and rotational energies performing CASSCF classical dynamics, we here prove how the same oxaziridine STC can account for both fast and slow photoproducts, depending on the region of the seam through which the ground state is populated. A roaming-type STC/CI has al…
Pre- and post-synthetic modulation of the ordering temperatures in a family of anilato-based magnets
2019
We report the synthesis and characterization of six novel heterometallic molecule-based 2D magnets with the bromanilato ligand (C6O4Br22− = 1,3-dibromo-2,5-dihydroxy-1,4-benzoquinone dianion) and six different benzene derivative molecules. The compounds, formulated as (NBu4)[MnCr(C6O4Br2)3]·1.75C6H5Br (1), (NBu4)[MnCr(C6O4Br2)3]·C6H5X with X = Cl (2), I (3) and CH3 (4) and (NBu4)[MnCr(C6O4Br2)3]·2C6H5X with X = CN (5) and NO2 (6), present the classical hexagonal honeycomb-(6,3) lattice with alternating Mn(II) and Cr(III) ions. The layers are packed in an eclipsed way along the a direction giving rise to hexagonal channels where the benzene derivative molecules are located with π–π interacti…
Benzene monitoring by micro-machined sensors with SnO2 layer obtained by using micro-droplet deposition technique
2011
International audience; SnO2 thin layers were deposited by the way of the micro-droplet technique. The sensor substrate consisted of a thin membrane developed on oxidised silicon wafer. The sensing layers were deposited by means of the micro-droplet technique into thin layers of about 100 nm. Such devices were tested for benzene detection. The obtained results showed a very high sensitivity for this chemical compound since 500 ppb were detected. The results presented in this paper were not focused on the reactional mechanism of benzene detection but rather on the development of a cheap and sensitive sensor using sol-gel and micro-droplet processes. Since these layers were elaborated using s…
Computational flow dynamics in a geometric model of intussusceptive angiogenesis.
2009
Intussusceptive angiogenesis is a process that forms new blood vessels by the intraluminal division of a single blood vessel into two lumens. Referred to as nonsprouting or intussusceptive angiogenesis, this angiogenic process has been described in morphogenesis and chronic inflammation. Mechanical forces are relevant to the structural changes associated with intussusceptive angiogenesis because of the growing evidence that physiologic forces influence gene transcription. To provide a detailed analysis of the spatial distribution of physiologic shear stresses, we developed a 3D finite element model of the intraluminal intussusceptive pillar. Based on geometries observed in adult intussuscep…
Ordering and dewetting in spin-coated films of a liquid crystalline main chain polymer
2006
Abstract The ordering of spin-coated films of a main-chain smectic liquid crystalline polymer with an azobenzene group connected by flexible spacers to a phenyl malonate unit has been studied as a function of film thickness using scanning force microscopy and UV/Vis spectroscopy. Already the as-prepared films are characterized by a significant out-of-plane orientation of the azobenzene groups. Annealing of films thicker than 7 nm results in aggregation and homeotropical alignment of azobenzene groups forming smectic layers parallel to the substrate. An optically isotropic mesophase was found upon annealing in the temperature range of smectic mesophase. Films thinner than the bilayer thickne…
