Thin fallout tuffs in the Duchesne River Formation in the Uinta Basin, Utah are evidence that volcanism was active in northern Nevada and Utah in the late Eocene. The Uinta Basin is a sedimentary basin that formed during the Laramide orogeny. Ponded lakes of various salinity filled and emptied and during the late Eocene the northern rim was dominated by a wetland/floodplain depositional setting. Most of the tuffs have rhyolitic mineral assemblages including quartz, biotite, sanidine, and allanite. Rhyolitic glass shards were also found in one of the ash beds. Biotite compositions have Fe/(Fe+Mg) ratios typical of calc-alkaline igneous rocks and clusters of biotite compositions suggest 3 or 4 volcanic events. Sanidine compositions from five samples grouped at Or73 and Or79. Only one sample had plagioclase with compositions ranging between An22 - An49. Some beds also contained accessory phases of titanite, apatite, and zircon. Whole rock compositions of the altered volcanic ash beds indicate these tuffs underwent post-emplacement argillic alteration, typical of a wetland/floodplain depositional setting. Immobile element ratios and abundances, such as Zr/Nb and Y are typical of a subduction zone tectonic setting and rhyolitic composition. 40Ar/39Ar ages constrain the timing of volcanism. One plagioclase and one sanidine separate from two different tuff beds yielded ages of 39.47 ± 0.16 Ma and 39.36± 0.15 Ma respectively. These dates, along with the compositional data seem to limit the eruptive source for these fallout tuffs to the northeast Nevada volcanic field. These new ages, along with previously published ages in the Bishop Conglomerate which unconformably overlies the Duchesne River Formation, constrain the timing of two uplift periods of the Uinta Mountains at 39 Ma and 34 Ma. Finally, the ages also date the fauna of the Duchesnean Land Mammal Age to be about 39.4 Ma as opposed to less precise earlier estimates that placed it between 42 and 33 Ma.

No / (137)Cs concentrations in ten species of foliose lichens collected within Tsukuba-city in August 2013 ranged from 1.7 to 35 kBq/kg. The relationships between (137)Cs in two dominant species, Dirinaria applanata and Physcia orientalis, and the air dose rate (muSv/h) at the sampling sites were investigated. (137)Cs in P. orientalis measured about 1 year after the Fukushima nuclear accident was correlated (r(2) = 0.80) more closely with the air dose rate than those measured after about 2 years (r(2) = 0.65), possibly demonstrating its continued value as a biomonitor to reflect ambient fall-out levels. In contrast, those of Dirinaria applanata were not correlated with the air dose rate in either year.

Video games' capacity for player choice makes them an excellent medium for expressing ethical dilemmas and developing the ethical thinking of players. However, translating complex ethical dilemmas to procedural games is challenging, particularly when the game creator intends to convey specific arguments in their work. This paper contains a close reading of ethical dilemmas in Fallout: New Vegas, Disco Elysium, and Frostpunk and applies Deleuze and Guattari’s (1987) concept of stratification as a means of understanding the process of collapsing the semantics of an ethical dilemma into the procedures of a digital game. It introduces the concept of consonance to refer to the consistency between procedural and semantic logic, and argues that the development of mechanics which maintain or enhance consonance is an important factor in creating persuasive procedural rhetoric about ethical topics.

Il s’agit de questionner les effets de cette figure sur la construction d’une mémoire du lieu vidéoludique exploré, ainsi que ceux sur la formation d’émotions. Ce mémoire débute par une mise en contexte et la définition des différents concepts de base que nous utiliserons, tels la ruine, les utopies et l’apocalypse. Ensuite, nous procédons à une analyse de la formation d’une mémoire d’un lieu vidéoludique et des effets des ruines post-apocalyptiques représentées sur ce processus, le tout appuyé par une étude de notre corpus : Bastion, Journey et Fallout 3. Finalement, nous faisons le même cheminement afin d’analyser la formation d’émotions en réaction aux différents éléments de design qui forment les ruines post-apocalyptiques dans les jeux observés. / This research proposes an analysis of post-apocalyptic ruins in video games. We will question the effects of this figure on the creation of a memory based on the explored space and on the formation of emotions. This thesis will begin by establishing the context of our definitions and the different concepts we will be using throughout, such as ruins, utopias and the apocalypse. We will then analyse the creation of a memory based on a videogame space and the effects of the represented post-apocalyptic ruins on the process, all of this backed up by a study of our corpus: Bastion, Journey and Fallout 3. In the last part, we will do a similar work to analyse the formation of emotions in reaction to the different design elements that constitute the observed games.

Le 36Cl est utilisé dans les études hydrologiques en raison de son caractère conservatif. Il apparaît cependant que le Cl- participe à un cycle biogéochimique complexe associé au turnover de la matière organique. Le flux de 36Cl atmosphérique a été déterminé (suivi mensuel des eaux de pluie sur deux ans) et varie saisonnièrement avec des valeurs accrues au printemps - été. L'importance de la période d'échantillonnage a été mise en évidence indiquant qu'une période de 6 mois est recommandée afin de lisser les variations saisonnières et les pics sporadiques du flux de 36Cl. Le flux atmosphérique moyen du 36Cl à notre site, constituant le flux d'entrée majoritaire dans son cycle biogéochimique, est de (75±6) atoms.m-2.s-1.La distribution du Cl et du 36Cl a été étudiée dans l’écosystème forestier grâce au développement des protocoles adéquats. 72% du Cl et 80% du 36Cl sont présents sous forme organique dans le sol alors qu'ils sont principalement sous forme inorganique dans la végétation. Les rapports mesurés dans la végétation (~ 200 x 10-15 at.at-1) sont similaires à ceux provenant des apports atmosphériques (~ 180 x 10-15 at.at-1) et ceux mesurés dans le sol sont un ordre de grandeur supérieur. Ces derniers augmentent significativement à 5-15 cm dans la fraction organique du profil de sol alors que dans la fraction inorganique une faible augmentation apparaît à 15-30 cm. Nous attribuons ces observations au recyclage du 36Cl du pic nucléaire des années 1950-1960. Ces résultats indiquent que la distribution du 36Cl diffère de celle du Cl suggérant des processus dynamiques d’immobilisation et de remobilisation du 36Cl liés au renouvellement de la matière organique. / 36Cl is widely used in hydrological studies since it is considered as a conservative tracer. However it appears that Cl- participates in a complex biogeochemical cycle linked to the organic matter turnover. The 36Cl atmospheric fallout rate has been determined (monthly record of rainwater samples during two years) and varies seasonally with higher values during spring – summer. The sampling period should at least span 6 months to avoid any biais in the fallout rate determination due to the monthly variations or any sporadic bursts of 36Cl. The mean 36Cl fallout rate at our site, corresponding to the main input of its biogeochemical cycle, equals (75±6) atoms.m-2.s-1. The distribution of Cl and 36Cl has been studied into the ecosystem thanks to the development of appropriate protocols.72% of the Cl and 80% of the 36Cl are contained in the organic fraction in soil while they are mainly in inorganic form in the vegetation. 36Cl/Cl measured in vegetation (~200 x 10-15 at.at-1) are within the range of the ones measured in the rainwater samples (~180 x 10-15 at.at-1), while the 36Cl/Cl ratios are 10 times higher in soil. 36Cl/Cl in soil increase significantly at a depth of 5-15 cm in the organic fraction while a slight increase is observed in the inorganic fraction at 15-30 cm deep. This suggests that 36Cl originating from the massive input of 36Cl introduced in the atmosphere more than 50 years as a consequence of nuclear tests, might still be recycling.These results emphasize that the distribution of 36Cl and Cl are not similar suggesting a possible occurrence of dynamic processes of 36Cl accumulation and release associated with the turnover of the organic matter.

Master´s thesis deals with the issue of internal microclimate of clean rooms. The experimental part focuses on aerosol and microbial microclimate. Different operating and intervention rooms were measured and then evaluated whether the cleanroom would comply with the standard cleanliness class even in normal operation after previous validations. The microbial examination of different clean spaces investigated the extent to which the exact passive fall method and its evaluation were time-dependent. From the data the correct desing of the air-conditioning system and its subsequent realization and regultion were verified. The theoretical part describes requirements for clean rooms according to SÚKL-LEK 17 and ČSN EN ISO 14644-1. In addition, a detailed methodology of the procedure of air-conditioning implementation is elaborated to the final validation and testing of clean rooms.

This master's thesis deals with the issue of volcanic ash as a complex and its impact on aviation, including the volcanic activity itself (conditions for its existence, for existence of eruptions and their basic products). In addition, the thesis also deals with effect of volcanic ash on aircraft and airports, possibilities of its detection or monitoring as well as mechanism of its spreading in airspace. The emphasis is laid mainly on air incidents related to volcanic ash and on danger it poses to the airspace of the Czech Republic.
