[ENG] This Master’s thesis explores the rendering of Spanish insertions in voice-over translations of Hollywood films into Lithuanian. The aim of the study is to analyze how Spanish elements are translated in this context. To achieve this, the objectives include reviewing relevant literature, identifying Spanish insertions and their functions in selected films, determining the translation techniques used, and assessing whether these techniques effectively convey the original functions. The study defines voice-over translation, distinguishing it from film voice-over and other audiovisual transfer modes like dubbing and subtitling, highlighting its unique synchronization constraints and the co-presence of original and translated languages. It also discusses the principles of voice-over translation, such as isochrony and synchrony, and the challenges it poses, including the need to balance comprehensibility with linguistic accuracy. The study further explores multilingualism in cinema, ...

[ENG] The Masters thesis analyses the role of social workers in reducing the stigma of mental disability. The stigma of mental disability can lead to difficulties such as reduced access to the labour market, poor health services, poverty, homelessness and many other problems. The effects of stigma cause them to accept negative societal prejudices and to lose self-confidence. The stigma of mental disability is a multifaceted and acute problem worldwide, but there is a dearth of research in this area, especially on long-term interventions and follow-up actions to tackle stigma. Although the role of social workers in reducing the stigma of mental disability is argued to be important, there is a dearth of research on how social workers work in this area. The aim of this paper is therefore to examine the role of social workers in reducing the stigma of mental disability. The theoretical part of the thesis discusses the concept of mental disability stigma and its impact on the psychosocial w...

Dissolved iron (dFe) is an essential micronutrient for sustaining life in the surface ocean. Nearly four decades of research dedicated to understanding sources, cycling and biogeochemical modifications of Fe sources in the global oceans has generated a significant body of research supporting the idea that the concentration of Fe in the surface ocean exerts significant controls on primary production and carbon uptake in the surface ocean. Creation of the GEOTRACES program greatly increased the spatial and temporal resolution of high-quality trace element and trace element isotope data revealing new insights into the global Fe cycle, especially through the use of dissolved iron isotopic compositions (δ56Fe). It has been clearly demonstrated that dissolved Fe isotopic compositions are a useful tracer of point source enrichments and biogeochemical processes in the interior ocean. However, key questions remain regarding the utility of δ56Fe as a tracer of margin sources over long distance...

Understanding the drivers of type 2 diabetes (T2D) is essential to slowing its global rise. While lifestyle and genetics play important roles, they likely do not fully explain the growing burden, highlighting environmental exposures as potential risk factors for T2D. This investigation is particularly important for African Caribbean populations, who have a high prevalence of T2D and are underrepresented in environmental health research. Historically, studies have focused on the health effects of individual metals, but recent approaches have shifted toward examining the metal mixtures to better reflect real-world conditions. Similarly, incorporating the study of metabolically important physiological characteristics like myosteatosis (fat infiltration of skeletal muscle) adds further nuance to our understanding of the environmental effects on early metabolic dysfunction. The first aim characterized urinary metal concentrations and identified sociodemographic, dietary, and lifestyle predi...

D’un point de vue de risque écologique, il est important de différencier les nanoparticules manufacturées (ENP) des nanoparticules d’origine naturelle (NNP). L’objectif de cette recherche était de caractériser et de quantifier les nanoparticules de dioxyde de titane et d’oxyde de zinc (NPs) libérées par deux écrans solaires commerciaux dans trois matrices aqueuses (eau ultra-pure, eau dure et eau douce naturelle) après deux expositions de courte durée : environ 15 minutes et environ 60 minutes. Un spectromètre de masse à plasma inductif couplé avec un détecteur à temps de vol (ICP-ToF-MS) a été utilisé pour détecter les éléments dont les rapports masse/charge (m/z) allaient de 26 à 210 u.m.a. dans des particules individuelles (SP). La composition élémentaire, la distribution de masse et les rapports isotopiques (47Ti/49Ti et 66Zn/68Zn) des NP individuelles ont été étudiés afin de déterminer dans quelle mesure il était possible de différencier les ...

Volatilomics is an emerging discipline aimed at characterizing volatile metabolites in various samples, with applications ranging from the food industry to biological research, serving as a powerful tool in food quality and authenticity assessments. Comprehensive two-dimensional gas chromatography (GC×GC) coupled with flame ionization detection (FID) and mass spectrometry (MS) combines structural information (MS) with robust quantification (FID). Traditionally, data from the two detectors are analyzed separately. The challenge tackled in this study has been the fusion of MS and FID chromatograms to improve the reliability of pattern recognition during template matching while enabling quantitative volatilomics on a large set of detectable features. The process of features matching across chromatograms is guided by the spectral similarity provided by MS information, thereby reducing mismatches while, at the same time, extracting the FID responses for accurate quantification. This approa...

This dissertation presents research on characterization, classification and quantitative analysis of single-particles (sp) using inductively coupled plasma time-of-flight mass spectrometry (ICP-TOFMS). spICP-TOFMS can be used for the quasi-simultaneous analysis of elements across the entire atomic mass range, spanning from 6Li to 238U, at high time resolution from particle produced transient events. Chapter one provides a general introduction and fundamentals of ICP-MS. A brief overview of the mass analyzers coupled with ICP for elemental analysis is provided, along with their limitations that have driven advancements in mass analyzer technology. The evolution of mass analyzers, from detecting elemental signals and measuring multi-element or isotope ratios to state-of-the-art simultaneous multi-element analysis during single transient events, is presented. A brief introduction of single particle analysis using ICP-MS with advantages and disadvantages of various mass analyzers in single...

Mischleiter gewinnen als Elektrodenmaterialien für die elektrochemische Energieumwandlung, z. B. in Festoxidbatterien oder Brennstoffzellen, zunehmend an Bedeutung. Das Sauerstoffdefizit im Kristallgitter beeinflusst die ionische Leitfähigkeit und wird üblicherweise durch δ in der chemischen Summenformel ausgedrückt. Dieser für die Materialeigenschaft wesentliche Parameter wird jedoch in den meisten Fällen nicht direkt gemessen, da Sauerstoff nur indirekt mit wenigen Analysemethoden wie der Thermogravimetrie (TGA) quantifiziert werden kann.Aus diesem Grund wird in dieser Arbeit die laserinduzierte Plasmaspektroskopie (LIBS) als neue Möglichkeit zur Quantifizierung von Sauerstoff-Leerstellen in Mischleitern vorgeschlagen, da sie den direkten Nachweis aller Elemente, einschließlich Sauerstoff ermöglicht. Darüber hinaus handelt es sich um eine sehr schnelle Messmethode, die keine langwierige Probenvorbereitung erfordert. Bei der LIBS trägt ein Laserstrahl Probenmaterial von de...

We have explored crystal growth, dissolution, and cation exchange reactions in Mg (hydr)oxides and carbonates in the presence of H2O and CO2 to constrain mechanisms, reactions rates, and efficiencies for cement production, direct air capture (DAC), and dolomitization of limestone. Our time-resolved X-ray diffraction (TRXRD) observations of periclase hydration in an acetic acid buffer solution are best explained by solid-state diffusion of H+ along the (111) planes of periclase. Counter to prior interpretations, no amorphous intermediate between periclase and brucite was observed in this study. The evolution of lattice parameters and microstrains indicates the development of stacking faults along the c direction of brucite generated by different packing arrangements of the oxygen atoms in periclase and brucite. As these stacking faults disappeared, the microstrain along c (S004) decreased by 98.5 % and the lattice parameter c increased by 8 %. Both Fe- and Mn-doped brucites absorbed mor...

In an increasingly technologically advanced and industrially developed world, the depletion of current reservoirs of critical elements poses an important risk. Consequently, identifying new exploitable reservoirs, while ensuring environmental sustainability, is of paramount importance. The evaporite deposits of Realmonte, Racalmuto, and Petralia, located in Sicily (provinces of Agrigento and Palermo), formed during the Messinian Salinity Crisis acme (5.97-5.33 Ma), represent a vast reservoir of evaporitic minerals that currently mined for halite, which is used in both the food and industrial sectors. However, in addition to halite, these deposits contain clay-rich layers and potassium and magnesium sulphates and chlorides, which precipitated under extreme evaporitic conditions when brine concentration reached 70-90 times that of seawater, which potential as a source of critical raw materials (CRMs) remains largely unexplored. This doctoral research aims to provide a detailed geochemica...

Due to their unique properties, nanoparticles (NPs) play a critical role in various fields such as catalysis, materials manufacturing and medicine. Therefore, the need for accurate characterization of NPs is high for manufacturing processes as well as for assessing the impact on the environment and human health. Single particle (SP) inductively coupled plasma (ICP) mass spectrometry (MS) has become a valuable analytical tool for sensitive investigation of NP composition. The ion signal durations of NPs produced in the ICP are in the order of a few hundred microseconds, which allows the analysis of a single element per NP using modern ICP-MS instruments. However, due to the sequential measuring principle of quadrupole mass analyzers, a settling time between m/z values of interest is required, therefore prolonging the needed time for the acquisition of one data point. This prevents conventional mass analyzers from dual-elemental analysis of NPs. However, using modern triple quadrupole MS...

In orthodontics, multi-bracket therapy uses alloys that are not completely corrosion-resistant under the conditions of the oral cavity. The amount of released metal ions and their effects on the body have not yet been comprehensively evaluated. The aim of this pilot study was to investigate the extent to which wearing a multi-bracket appliance (MBA) influences the human immune system and whether possible sensitizations are related to the amount of metal ions released in saliva. For this purpose, a new protocol was designed to test the possibility of detecting sensitization in connection with orthodontic treatment. 30 patients (18-35 years of age) were divided into three equal groups (G). The MBA was removed from the unbanded group (G1) at the start of the study, and the MBA was inserted into the banded group (G2). G3 represents the untreated control group. During a study period of 21 days, saliva and blood samples were collected at four different time points (T1-T4). The MBA collected ...

Gray wolves (Canis lupus) in Southeast Alaska exhibit diverse foraging strategies shaped by regional ecological factors. Stable isotope (δ13C and δ15N) and trace element (TE) analyses were used to evaluate dietary patterns and contaminant exposure in four wolf populations from northern Lynn Canal (Douglas Island, Juneau, Gustavus, and Pleasant Island) from wolf hair samples collected from 2013-2021, along with sea otter (Enhydra lutris) hair in wolf scat collected in 2018-2019. Stable isotope ratios revealed that Juneau wolves predominantly consume terrestrial prey such as Sitka black-tailed deer (Odocoileus hemionus sitkensis) and mountain goats (Oreamnos americanus), and wolves on Douglas Island mainly consume Sitka black-tailed deer. In contrast, wolves from Gustavus and Pleasant Island exhibited enriched isotopic signatures, indicating a significant incorporation of marine-derived prey, particularly sea otters. Analysis of TEs revealed higher concentrations in wolves consuming ma...

Catalyst size, morphology, and crystal structure play crucial roles in determining the activity and selectivity of electrochemical CO2 reduction reactions, which are known to change during the reaction process. A comprehensive understanding of how, when, and why these parameters evolve under operational conditions is essential for developing stable, efficient, and selective catalysts. In this study, we reveal that formate, one of the reaction products, contributes to the degradation of copper catalysts through a ligand-assisted dissolution mechanism. Utilizing in situ electrochemical atomic force microscopy and ex-situ scanning and transmission electron microscopies, we observed a significant reduction in the size of copper nanoparticles, which decreased from over 30 nm to less than 10 nm in diameter within 60 min of CO2RR. The temporal production of formate correlated with the particle size changes. Furthermore, analysis of the electrolyte using inductively coupled plasma optical emis...

Human activities have a strong impact on global climate and natural ecosystems, yet the extent of their influence on long-term natural erosional processes remains poorly determined. A quantitative analysis is needed. The Ayeyarwady River, renowned for its large sediment flux ranking second in Asia, provides a compelling case study. We here show that extensive anthropogenic activities in the Ayeyarwady catchment have strongly accelerated erosion rates compared to natural benchmark levels, thereby contributing to its high sediment discharge. To highlight this point, we compared present-day erosion rates calculated from sediment fluxes with long-term natural erosion rates derived from detrital-apatite fission track (AFT) and cosmogenic 10Be data. Our findings reveal a stark contrast. Long-term natural erosion rates were notably higher in the Upper Ayeyarwady (0.06-0.34 mm/a) than in the Upper Chindwin (0.02 ± 0.005 mm/a), whereas present-day erosion rates are three times higher in the Up...

Carbon mobilization at subduction zones can be constrained by focusing on Sr as a proxy, as Sr readily substitutes for Ca—a major cation in the crystal structures of carbonates. Unmelted high/ultrahigh pressure (HP/UHP) pelitic metasediments exhumed from less than 100 km depth along the slab-mantle interface show loss of Sr and retention of most other incompatible trace elements, when compared with their potential protoliths, for example, average shales/average upper continental crust/average subducting sediments. Sr and CaO/SiO2 in subducting sediments and unmelted HP/UHP metasediments are correlated, suggesting that Ca-carbonate is one of the major hosts for Sr in subducting sediments, and that Sr and carbonates are lost during subsolidus devolatilization of subducting HP/UHP metasediments beneath forearcs. In turn, the elevated Sr in arc magmas suggests that carbonated Sr-rich wedge peridotites may be dragged down into the source of arc magmas via wedge convection, where they cont...

The Kallianos Au-Ag-Te deposit is a Cenozoic orogenic-style deposit on Evia, hosted in the Cycladic Blueschist Unit. Integrated field observations and isotopic data illustrate a connection between the structural architecture that hosts mineralization in the deposit and the regional stress field associated with a crustal-scale detachment, the North Cycladic Detachment System, implying a first-order paragenetic relationship to post-orogenic extension. Mineralized and barren veins occur alongside parallel faults and joints in two distinct orientations, each locally defining conjugate or en-echelon sets. Younger sub-vertical tension gash sets (V2, V3) cross-cut older transposed and boudinaged mineralized veins (V1). Sulfide mineralization is hosted in steeply dipping cm-scale qz ± cal ± ab V3 veins. Structural relationships show cross-cutting of NW-striking V2 by NNW-striking V3 veins. The latter two vein sets opened orthogonal to the NE-trending stretching lineations, associated with br...

The Southern Ocean today is a globally relevant sink for atmospheric carbon dioxide ( ), where the biological uptake of carbon through primary productivity is largely controlled by widespread iron (Fe) limitation. We analyze observations from a submesoscale-resolving cross-section of the Antarctic Circumpolar Current (ACC) obtained around one thousand kilometers downstream of South Georgia in the Atlantic sector during austral spring 2022. Vertically integrated chlorophyll peaked in a strong ( 250 mgChl-a m−2) phytoplankton bloom within the central portion of the jet associated with the Southern ACC Front. We infer that winds drove a northward Ekman transport of dense water across the front and that this destabilized the water column, leading to an Ekman Buoyancy Flux (EBF) and enhanced vertical mixing ( −2 m2 s−1) across the base of the mixed layer. Using in situ measurements of dissolved iron, we estimate a net flux to the bloom of up to 3 μ molFe m−2d‒1 from a subsurface ...

The productive Northern Gulf of Alaska (NGA) ecosystem is impacted by spatiotemporal variability in nutrient distributions and ratios. Due to its advective nature and wide (50-150 km) continental shelf, the NGA may act as a nutrient source to the greater NE Pacific. Using high-resolution data from 11 seasonal (spring, summer, fall) research cruises (2018-2023), we examined regional drivers of nutrient fields. We found that variable sources of micro- and macronutrients influence their distributions and ratios. For example, relative to cellular nutrient quotas for coastal diatoms, surface dissolved Fe (dFe): nitrate (NO3−) ratios indicated an Fe-replete regime near river outflows throughout the year. In contrast, far from freshwater and subsurface Fe inputs, this ratio indicated potential Fe stress or limitation within outer waters during spring. Near the seafloor, a pool of high dissolved micro- and macronutrients highlighted variable nutrient sources (sedimentary and deep offshore wa...

Abstract Oceanic photosynthesis contributes to approximately half of the Earth’s net annual primary productivity. Marine photosynthetic productivity has a high degree of heterogeneity due to spatial and temporal co-limitations of light, temperature, and/or nutrients. Across coastal, near-shore, and open ocean regions, insufficient concentrations of key nutrients (e.g., N, P, Fe) can limit primary productivity. Although studies have shown a significant increase in primary productivity with the addition of low doses of trace nutrients, a sustainable approach to reliably deliver and maintain low doses of nutrients and ensure their bioavailability, remains a challenge. Chemical nutrient addition has relied on the use of chelating agents to ensure nutrient bioavailability, but synthetic chelators are persistent environmental pollutants. In this study, we demonstrate for the first time the use of a controlled electrochemical nutrient delivery (CEND) approach to accelerate the growth of phy...

The increasing resistance of influenza A viruses to adamantane-based antivirals underscores the need for new inhibitors targeting both wild-type (WT) and mutant M2 ion channels. Here, we report the synthesis and biological evaluation of polycyclic cage amines designed to replace the adamantane scaffold as M2 inhibitors. These include ring-contracted and ring-expanded analogues, evaluated both as primary amines and as aryl-/heteroaryl-substituted derivatives. Most of the polycyclic amines inhibited the WT M2 channel as demonstrated by electrophysiological assays. Among them, compound 10, a 3,4,8,9 tetramethyltetracyclo[4.4.0.0 3.6 .0 4.8 ]decan -1-amine, emerged as a triple blocker active against M2 WT, M2 L27F, and M2 V27A channels. In contrast, compound 6c, a noradamantane isoxazole derivative, showed selective inhibition of the S31N mutant. Although no antiviral activity was observed against influenza A virus in infected cell assays, both compounds 6c and 10 displayed significant ant...

Determining the provenance history of Jurassic sediments in the southwestern Tarim Basin is crucial for deciphering the tectonic evolution of the Western Kunlun−Pamir Paleo-Tethys Realm, which forms the northwesternmost segment of the Himalayan-Tibetan Plateau. Yet, the detailed spatial provenance variation of these strata is poorly constrained. This study integrates field observations from three outcropping sections (cumulative thickness of ∼6800 m) and three wells (∼3600 m) from four distinct regions: Qimgan, Oytag, Toyunduk-Kyzyltau, and Fusha. Samples were collected for analysis of sandstone petrology (n = 54), heavy mineral assemblages (n = 18), and detrital zircon U-Pb geochronology (n = 10) to delineate the spatial differences in Jurassic provenance. The results indicate that the southwestern Tarim Basin can be demarcated into two tectonic domains: (1) Detrital zircons in the Qimgan and Oytag regions were predominantly derived from nearby Triassic backarc volcanic rocks.

The late development of the easternmost Neo-Tethys Ocean was marked by two episodes of Cretaceous arc magmatism in Luk Ulo, Central Java. However, the thermal evolution process of their magma remains enigmatic. Here, we present new apatite U-Pb geochronology and geochemistry data from the Luk Ulo granitoids in Southeast Asia showing two distinct populations during the Early (112−107 Ma) and Late (72−68 Ma) Cretaceous epochs. However, the Early and Late Cretaceous granitoids record different mineral crystallization histories. The magma cooling rate for the Early Cretaceous granitoids is 56−347 °C/m.y., whereas the Late Cretaceous rate is >275 °C/m.y. The Early Cretaceous granitoids contain ilmenite, and show low zircon Ce4+/Ce3+ ratios (0.5−33.5) and ΔFMQ values (−6.4 to −1.3) with low whole-rock V/Sc ratios (0.5−4.2), which indicates low magmatic oxygen fugacity (fO2). However, the Late Cretaceous granitoids exhibit high zircon Ce4+/Ce3+ ratios (29.6−339.5) and ΔFMQ...

Identification of glacial influence in ancient active volcanic arc basins is challenging due to the overprinting effects of tectonism on the climatic fingerprint. The Neoproterozoic West Avalonian terrane records protracted arc volcanism within thick volcanic-sedimentary successions containing glacial diamictites of the Gaskiers glaciation (ca. 580 Ma). Such glaciogenic strata are recognized from deep- and shallow-marine settings in two basins in the Avalon zone of Newfoundland, i.e., St. John’s and Bonavista Basins, offering an opportunity to disentangle changes in sediment provenance through terrane-scale glacial cycles. This study provides ∼1800 single-grain detrital zircon U-Pb dates combined with zircon trace-element and Lu-Hf isotopic data from the glaciogenic Mercantile and Trinity Diamictites and underlying units (e.g., Monk Bay, Jones Pond, and Plate Cove East Members) in the Bonavista Basin. The maximum depositional ages of the studied units approach their depositional ag...
