[ENG] The masters thesis explores the integration of international television franchises and adaptations into Lithuanian television channels and streaming platforms, aiming to uncover the connections between creators decisions and audience behavior. It examines how global franchises, such as The X Factor or Lithuania’s Got Talent, are adapted for the local market by incorporating cultural elements, and how streaming platforms like Netflix and Go3 are transforming content creation practices. The study highlights platform policies that provide creators with greater freedom to experiment but also pose challenges due to intense competition and high production standards. The impact of binge-watching on audience behavior and streaming content consumption habits is also analyzed. Quantitative and qualitative research reveals that Lithuanian viewers tend to prefer adaptations that are culturally tailored to the local market....

[ENG] This Masters thesis examines how the use of artificial intelligence (AI) technologies in law enforcement institutions is reflected in Lithuanian mass media discourse and what aspects of social control emerge in this representation. The theoretical basis of the thesis is based on the approaches of three classical criminological theories: Foucaults concept of discipline and panoptic monitoring, Hirschis theory of control of social relations, and Cohens concept of net-widening. The empirical part of the study used a mixed methodological model: the quantitative analysis included 211 articles, and the qualitative analysis included 33 analytical texts published on the four largest Lithuanian news portals in the period 2020-2025. The study revealed the growing diffusion of IoT technologies and law enforcement discourse, especially after 2023, and the dominant link between this topic and the discourse on security, surveillance and privacy. It found that the introduction of IoT in law enf...

The thesis investigated how shame culture manifests itself in Finnish dress and the process of a clothing designer's work. Understanding the relationship between cultural shame and clothing and the dynamics between them expands the understanding of dress codes and the rules associated with them, and supports the development of Finnish design going forward. The research was limited to discussing women's formal wear in the 2020s. The research was carried out using document analysis, interviews and observation. For this purpose, three Finnish clothing designers were interviewed and, in addition to the interviews, people's dressing was observed in the Unelmahäättv series and in the TV broadcasts of the President's Independence Day reception. As part of the thesis, a collection was designed that reflects the research results and ways to break the shame culture. The research shows that Finnish shame culture manifests itself most noticeably as a fear of standing out from the crowd, which is...

Cadmium is a toxic metal that can cause adverse health effects such as kidney, bone, and liver damage, even at very low concentrations. By reason of its proven carcinogenicity in humans, it is classified as a Group 1 carcinogen by the IARC. Despite usage restrictions, cadmium remains particularly prevalent in occupational environments. Therefore, assessing workers' exposure to low doses is essential and relies on appropriate biological monitoring. This PhD thesis focuses on the development of specific analysis methods of cadmium in blood as a relevant biomarker of occupational exposure. The pharmacokinetics of cadmium in blood highlights two phases of elimination, depending on its different physicochemical forms: a short one (less than three months) and a long one (over ten years). Both were studied from two types of blood-fraction analysis (erythrocytes and plasma). In addition, cadmium speciation in plasma was also implemented to differentiate cadmium-protein complexes. These methods...

Lithium-cesium-tantalum (LCT) pegmatites are a key source of economic lithium. The timing of LCT pegmatite crystallization within the context of an orogenic system (i.e., pre-, syn- and post-orogenic) appears to vary globally and exerts a primary influence on the distribution of lithium mineralization in orogenic belts. The recent advances in in-situ Rb-Sr mica geochronology have enabled the direct dating of lepidolite, a major phase in LCT pegmatites. When combined with in-situ Rb-Sr, Lu-Hf, and U-Pb geochronology on other related major and accessory phases, the timing of LCT pegmatite crystallization can be accurately determined and placed in the context of a region’s magmatic and thermometamorphic history. Here, we present new in-situ Rb-Sr, Lu-Hf, and U-Pb geochronology data and results of petrological modeling from an east to west transect of the Benin-Nigeria shield to constrain the timing of magmatism, metamorphism, and LCT pegmatite crystallization related to the Pan-African ...

Since the discovery of Ti mass-independent and mass-dependent variations in meteorites and in terrestrial rocks and minerals, Ti isotopes have become a powerful tool for tracing isotope anomalies in solar system materials and fractionation processes in differentiated bodies. In particular, mass-dependent fractionations have recently proven useful in a variety of high temperature applications including magmatic differentiation of the Earth’s mantle, the evolution of the continental crust, as well as mineral resources. These applications are made possible by continued advances in mass spectrometry, in addition to continued development of techniques for solution and in-situ measurements. In this chapter we review the state-of-the-art approaches for the measurement of mass-dependent Ti isotope variations, and provide a brief synopsis and relevant references to their geochemical applications....

The seeds of Schinziophyton rautanenii (manketti) and Guibourtia coleosperma (ushivi) could have great potential as food and food ingredient due to their valuable nutritional properties that might make them potential candidates for Novel Foods. However, only little has been reported about their mineral nutrient composition. Hence, detailed analysis on the macro- and microelement concentration was performed using inductively coupled plasma sector field mass spectrometry (ICP-SFMS). Method was validated for the analysis of target analytes regarding linearity, instrument precision, limits of detection and quantification, repeatability precision, and accuracy of results (confirmed using certified reference materials). Results obtained showed that manketti nuts offer a valuable source for macroelements Mg, Ca, P and K (571 ± 27 mg/100 g, 225 ± 13 mg/100 g, 1138 ± 63 mg/100 g and 750 ± 47 mg/100, respectively).

Reef-associated fishes are integral components of marine ecosystems; many also support recreational, commercial, and subsistence fisheries. The sustainable management of these fisheries requires a detailed region-specific understanding of population age structure so that size and age data of fisheries species can be used to estimate life history parameters. Bomb-produced radiocarbon (14C) records are sparse in the western North Atlantic Ocean (WNAO); a need exists to establish new chronologies in regions that are fished to allow use of this unique tool in age validation studies. Utilizing known-age otolith material from reef-associated demersal fishes collected from continental shelf habitats of the southeastern U.S. (SEUS), we determined that a distinct regional 14C chronology exists for shallow SEUS waters, differing from 14C reference chronologies for the adjacent regions of Bermuda, Florida Keys, and north Caribbean. Our results provide additional 14C data from the WNAO for investi...

The rapid accumulation of conglomerates not only preserves tectonic episodes and uplift/denudation histories of the orogenic belt, but also correlates with the coupling process of basin and mountain. Two units of conglomerates that belong to the third (Mbr 3) and fourth (Mbr 4) members of the Upper Triassic Xujiahe Formation, are distributed along the northern Sichuan basin. Mbr 4 has an unconformable contact on Mbr 3. Mbr 3 is dominated by carbonate gravels forming fan-shaped deposits distributed discontinuously whereas Mbr 4 consists of massive quartzite gravels that extend eastward continuously. Detrital zircon U-Pb data show the peak age of 227 Ma from the Qinling orogenic belt are widespread in Mbr 3, but occur in only the central part of the northern Sichuan basin of Mbr 4. However, paleocurrent ndicators and sandstone petrologic data reveal both units were sourced from the Qinling orogen. We interpret the differences in clastic compositions and U-Pb ages as reflecting discrepant...

Methanogenic archaea contribute 1-2 Gt of methane annually, impacting both global carbon cycling and climate. Central to their energy metabolism is a membrane [ndash]bound, sodium-translocating methyltransferase complex: the Na+ tetrahydromethanopterin:CoM-S [ndash]methyltransferase (Mtr complex), which catalyzes the methyl transfer between two methanogen specific cofactors. This exergonic methyl transfer step is coupled with a vectorial sodium ion transport from the cytoplasm to the cell exterior and is the only energy conserving step in hydrogenotrophic methanogenesis. Here, we present a 2.1 Å single-particle cryo-EM structure of the full Mtr complex from Methanosarcina mazei. Our structural model encompasses the entire complex, reveals the arrangement of archaea phospholipids, the architecture of the sodium ion binding site, and the structure and interactions of all catalytic subunits. Most strikingly, we discover and characterize MtrI, a previously unannotated small open reading f...

Abstract Despite various therapeutic advancements in cancer, heterogeneity in the tumor microenvironment is a major hindrance to the overall efficacy of treatment. In this study, we focus on the most abundantly found cellular stromal components - fibroblasts - which can be tumor-promoting or tumor-suppressing based on the extent of disease progression and numerous additional factors. In the studies described herein, we evaluated their role in influencing chemotherapy as well as in immunotherapy using colorectal cancer (CRC) cell line-derived 3D tumor constructs. Our initial efforts centered on common chemotherapeutic agents utilized in CRC. However, while the presence of fibroblasts often did influence chemotherapy efficacy, a clear and consistent increase or decrease in efficacy was not obvious. We then focused subsequent studies on natural killer (NK) cell-based immunotherapy efficacy. There are numerous components and pathways involved in tumorigenesis and tumor-immune cell interact...

Iron is crucial for cellular metabolism and cell growth. Nevertheless, in humans, both iron deficiency and disorders of iron overload are widespread. How cellular iron content varies depending upon iron availability, and how this influences cell function is poorly characterised. We developed a method to quantify metals in hundreds of cells per minute via single-cell inductively-coupled plasma mass spectrometry (sc-ICP-MS), and used this to explore iron usage by immune cells. Activated murine T-cells exposed to a 625-fold titration of extracellular iron maintained close homeostatic control, with iron content varying by ~20%. However, these variations strongly correlated with activation characteristics and proliferation. Running sc-ICP-MS downstream of flow cytometric sorting showed that murine T-cells and B-cells ex vivo exhibit similar mean and heterogeneity of cellular iron while splenic macrophages contain twice as much iron and more heterogeneous iron content. Finally, activated hum...

Potassium isotope ratios (δ41K) were determined for eighteen Chinese geological reference materials (RMs, GSR series) encompassing igneous, metamorphic and sedimentary rocks. K2O mass fractions (w) ranged between 0.15 and 7.5% in these RMs. Measurements were conducted using a collision cell MC-ICP-MS with sample-standard bracketing technique. The intermediate precision of K isotopic determination, based on measurement results collected over 2.5 years, was 0.04‰ (2s, n = 69) for in-house GSB K solution and 0.05‰ (2s, n = 63) for basaltic RM BCR-2. The accuracy of our data was assessed by comparison with previously published data and/or utilising two or three different measurement procedures. The high-precision δ41K values for these eighteen RMs span a wide range from -1.15‰ (GBW07122, GSR 15, amphibolite) to 0.28‰ (GBW07120, GSR 13, limestone), and data for six RM are presented for the first time, making them valuable references for quality assurance and inter-laboratory...

The Pingqiao deposit, a newly discovered large-scale fluorite-cookeite deposit in Guizhou, Southwest China, represents a new and unusual type of lithium (Li) mineralization. Recent exploration has identified over 90 kt of Li2O reserves. Using in situ laser ablation-inductively coupled plasma-mass spectrometry to analyze the primary Libearing mineral, cookeite, and associated minerals, as well as major and trace elements and Li isotopes of the ore-hosted strata, this study investigated the spatial distribution, occurrence, and enrichment mechanisms of Li. The study yielded new geological and geochemical evidence to improve our understanding of Li mineralization. The results indicate that two generations of cookeite (Ckt-I and Ckt-II) and fluorite formed during the same hydrothermal stage, with crystallization temperatures of between 95 °C and 270 °C. Ckt-I is enriched in light rare earth elements and exhibits a negative Eu anomaly (average of 0.55), which decreases in Ckt-II (average ...

The Moenave Formation of the Colorado Plateau region of western USA preserves the Triassic-Jurassic transition, a time period that saw one of the most significant climate disruptions in Earth’s history. During this time, major carbon (C)-cycle perturbations due to carbon release from the emplacement of the Central Atlantic Magmatic Province (CAMP) caused rapid climate change prompting the end-Triassic mass extinction (ETE). Here we present a Bayesian agemodel generated from new C-isotope chemostratigraphic records paired with highprecision detrital zircon U-Pb geochronology to constrain the stratigraphic placement of the ETE and Triassic-Jurassic boundary within the Moenave Formation. Maximum depositional ages of detrital zircon from the Moenave Formation range between 203.71 ± 0.09 Ma to 200.20 ± 0.17 Ma. A −6.0‰ C-isotope excursion within the middle Dinosaur Canyon Member (DCM) is correlated to the initial negative C-isotope excursion of the ETE, indicating that the lower to ...

The Tibetan Plateau has drawn significant research attention for its complex formation and uplift processes. While central and southern Tibet have been relatively well studied, northern Tibet remains less explored. This study integrates zircon and calcite U-Pb dating, detrital zircon analysis, and stable and clumped isotope analyses to refine the chronostratigraphy, paleoelevation, and paleo-drainage change in the Fenghuoshan Basin. U-Pb dating of a volcanic tuff from the lower Fenghuoshan Group yielded an age of 65−64 Ma. The volcanic tuff is underlain by detrital zircon age populations of 81 Ma and 75 Ma, as well as limestone ages of 79−77 Ma, which collectively supports a revised depositional onset of ca. 80 Ma for the Fenghuoshan Group. Clumped isotope analyses from the Erdaogou area reveal extremely high temperatures (>150 °C), which makes those samples unsuitable for paleoelevation reconstruction. However, paleosol carbonate nodules found in the northernmost partof the Erdao...

Crucial questions regarding the mineralizing processes involved in the formation of disseminated gold mineralization remain unresolved, which complicates our understanding of metal precipitation processes in these systems and impedes effective exploration. This study integrates petrographic and geochemical analyses of chlorite within barren and ore-bearing marble, granite, and granofels units from the Guocheng gold deposit in Jiaodong, China. The petrographic analysis of these samples indicates that ripidolite is the primary chlorite phase within altered wall rocks, replacing biotite, hornblende, and plagioclase via dissolution-crystallization. In contrast, ore-associated chlorite is dominated by brunsvigite and pyrochlore, forming by dissolution-migration-crystallization. The mineral chemistry of this chlorite indicates that ore-related chlorite has lower Fe2+/(Fe2+ + Mg2+) ratios and higher Fe3+ concentrations than chlorite within altered wall rock areas. This indicates relatively lo...

Plume-assisted subduction infancy, independent of plate tectonics and potentially applicable to Venus, is thought to have possibly occurred as an alternative architecture to the first subduction initiation in hotter early Earth in old oceanic plates. Yet, direct rock records are rarely preserved from young oceanic plates on a global scale. Here, we conduct geochemistry, zircon and titanite U-Pb-Hf isotopic analysis, and thermodynamic modeling, as well as Ti-in-zircon and Zr-in-titanite thermometers to reconstruct the pressure-temperature-time history of high temperature-low pressure granulite-facies rocks in the western Kunlun orogen. Relevant data show that they represent ocean island basalts (OIB) and were buried to ∼20−25 km, reaching 820−920 °C at ca. 200 Ma, and subsequently exhumed to ≤15 km during early cooling to ∼650 °C at ca. 185 Ma. Incorporating extensive existing data, plume-assisted intra-oceanic subduction infancy is proposed for the Paleo-Tethys ocean during...

An integrated understanding of H 2 generation, migration, trapping, and preservation is required to facilitate H 2 exploration. Hydrogen-rich gas discoveries in the São Francisco Basin, Brazil, enable investigation of these processes in intracratonic settings. We use major gas, stable-isotope, and noble gas isotope geochemistry to develop an advanced geochemical framework that demonstrates, via multiple lines of evidence, migration of components into the basin from underlying cratonic basement. Mass balance shows that hydrogen and helium derive from outside of the fracture-controlled reservoirs they were sampled from. Radiogenic noble gas data indicate at least two crustal sources for the accumulated gas, from different thermal environments; neon-isotope data suggest that one of these is the Archaean crystalline basement. The H 2 - and He-bearing gases are associated with the eastern part of the basin, above the Pirapora Aulocagen, where thick-skinned deformation associated with the A...

The Jinchuan copper-nickel deposit is the third largest magmatic copper-nickel sulfide deposit in the world and the largest in China, with a total proven nickel metal reserve of 6.25 million tons and an average nickel grade of 0.92% (Xue et al., 2023). Previous studies have been conducted on the mineralization process of the Jinchuan deposit. Existing studies have shown that the Jinchuan primitive magma experienced ~20% crustal contamination during its evolution (Chai et al., 1992a, 1992b; Li et al., 2004; Ripley et al., 2005; Song et al., 2009; Yang et al., 2018), and that crustal contamination is the key factor that causes sulfur saturation in the Jinchuan parent magma (Li et al., 2011). However, the specific source of contaminating materials and the melting mechanism of sulfides are still controversial (Lehmann et al., 2007; Duan et al., 2016; Tang et al., 2018; Ding et al., 2021; Xue et al., 2023).

Iron meteorites record a range of iron isotope compositions that hold valuable information regarding the evolution of their parent bodies. Interpreting this isotopic variability, however, requires experimental constraints on the equilibrium isotope fractionation between phases. It is thought that the cores of many iron meteorite parent bodies experienced fractional crystallization, during which crystallization of solid iron-nickel occurs from an increasingly non metal-rich liquid alloy. Phosphorus is thought to be one component of this alloy, and this study provides the first constraints on Fe-isotope fractionation between solid and liquid alloys in the Fe-Ni-P system. Experiments comprising Fe and P show a clear enrichment in the light isotopes of Fe in the liquid phase, which increases with the amount of phosphorus. Ni-bearing samples are offset from the trend defined by Ni-free experiments, which is accounted for by the change in the solid alloy phase from a body-centered cubic to f...

Multi-elemental, isotopic, spectroscopic and metabolomic analyses, aimed to pinpoint the origin of chicken, aiding label verification from Austria and two importing countries. Stable isotope ratios of nitrogen and carbon distinguished samples from different farms in Austria, Hungary, and Germany (95% confidence). Varied carbon isotope values in fillets suggested diverse diets among farms, indicating maize-rich diets for Austrian chickens (HU), with descending corn levels for RA and TI (Austria), U1 and U2 (Hungary), and least in PL farm (Germany). Discriminant analysis showed superior chicken classification precision and accuracy through elemental (94.6% and 97.7%), MicroNIR (81.1% and 93.2%), and amino acids analysis (82.3% and 85.9%). Merging elemental and isotopic data improved overall model performance to 95.7%, and 98.3%, respectively. Carbon stable isotopes proved effective in verifying maize-fed chicken, aiding fraud detection, while NIR handheld devices, particularly MicroNIR, ...
