Abstract:
Quartz crystal microbalances (QCMs) were utilized for the detection of the noble gas xenon (Xe) by combining them with different recognition layers such as permethylated calixarenes (tetramethyl-tert-butylcalix[4]arene (Cal4Me), hexamethyl-tert-butylcalix[6]arene (Cal6Me)), and polyurethanes, with covalently embedded Cal4OH (Poly4Cal), or Cal6OH (Poly6Cal). A third type of sensitive material is synthesized from polyacrylic acid (PAA) and polyvinyl alcohol (PVA) and utilized as a sensitive coating. The results demonstrate that the Cal4Me layer gives higher response towards Xe, while, by the use of a second uncoated QCM channel, the influence of ambient humidity could be nearly completely compensated by signal subtraction. Moreover, the Cal4Me sensor shows excellent reversibility and rapid response time, providing a potentially reliable way to determine Xe during anaesthesia.

Abstract:
The Maronia Cu-Mo ± Re ± Au deposit is spatially related to a microgranite porphyry that intruded an Oligocene monzonite along the Mesozoic Circum-Rhodope belt in Thrace, NE Greece. The magmatic rocks and associated metallic mineralization show plastic and cataclastic features at the south-eastern margin of the deposit that implies emplacement at the ductile-brittle transition, adjacent to a shear zone at the footwall of the Maronia detachment fault. The conversion from ductile to brittle deformation caused a rapid upward magmatic fluid flow and increased the volume of water that interacted with the host rocks through high permeable zones, which produced extensive zones of potassic and sodic-calcic alteration. Potassic alteration is characterized by secondary biotite + K-feldspar (orthoclase) + magnetite + rutile + quartz ± apatite and commonly contains sulfides (pyrite, chalcopyrite, pyrrhotite). Sodic-calcic alteration consists of actinolite + sodic-calcic plagioclase (albite/oligoclase/andesine) + titanite + magnetite + chlorite + quartz ± calcite ± epidote-allanite. The high-oxidation state of the magmas and the hydrothermal fluid circulation were responsible for the metal and sulfur enrichments of the aqueous fluid phase, an increase in O2 gas content, the breakdown of the magmatic silicates and the production of the extensive potassic and sodic-calcic alterations. Brittle deformation also promoted the rapid upward fluid flow and caused interactions with the surrounding host rocks along the high temperature M-, EB-, A- and B-type veins.

Abstract:
Skarn-like calc-silicate rocks are reported in spatial association with the Archean Cu–Zn–Ag massive sulphide deposits at the Manitouwadge mining camp, Ontario. Calc-silicates in the footwall of the Willroy mine occur as matrix to breccia fragments of garnetiferous quartzo-feldspathic gneiss and as lenses within garnetiferous quartzo-feldspathic gneiss and are composed of clinopyroxene, garnet, calcic amphiboles, wollastonite, plagioclase, K-feldspar, epidote, quartz, calcite, magnetite, and minor sulphides. Calc-silicates within the main orebody of the Geco mine are characterized by clinopyroxene, calcic amphiboles (Cl–K-rich hastingsitic and ferro-edenitic hornblende, ferro-edenite (up to 4.7 wt.% Cl); and ferroactinolite (6.7 wt.% MnO)), garnet, epidote (including an epidote rich in rare-earth elements and Cl), calcite, quartz, and abundant sulphides. Calc-silicates within the basal 4/2 Copper Zone of the Geco mine contain garnet, gahnite, sphalerite, ferroactinolite (8.5 wt.% MnO), epidote, quartz, biotite, plagioclase, chlorite, muscovite, K-feldspar, and pyrosmalite (with Mn/(Mn + Fe) ratio ranging from 0.21 to 0.61, and up to 3.9 wt.% Cl). The calc-silicates probably represent metasomatic remobilization of dispersed Ca (and Cl) from sea-floor hydrothermal alteration of mafic to intermediate volcanic rocks and are only indirectly related to the hypothesized syngenetic ore-forming processes for the associated base metal sulphide deposits. The calc-silicates formed initially at about 600 °C and 3–5 kbar (1 kbar = 100 MPa) in a mildly reducing environment (from 1 log unit above to 1 log unit below the fayalite–magnetite–quartz buffer) during the upper-amphibolite- to granulite-facies regional metamorphism and were altered subsequently at lower temperatures (<500 °C).

Abstract:
AbstractMg-Mn amphibole (tirodite), with or without pyroxmangite in the total absence of pyroxenes and high-calcic pyroxenoids, occurs in the Mn silicate rocks of the Sausar Group, India. The rocks were metamorphosed to amphibolite facies condition (T ∼ 650°C, P ∼ 6 kbar). Tirodite-pyroxmangite pairs developed in both carbonate-free and rhodochrosite-bearing assemblages. Also tirodite coexists with either kutnahorite or manganoan calcite in the absence of pyroxmangite. Mineral reactions inferred from modal abundances and compositions of the phases indicate stabilization of the amphibole alone from a bivalent cation-bearing residual unbuffered XCO2 system with XMn < 0.3. On the other hand, tirodite-pyroxmangite pairs appeared in unbuffered low to intermediate XCO2 assemblages with XMn > 0.35. Pyroxenes and high-calcic pyroxenoids did not appear in the present situation, though they occur elsewhere in rocks with broadly similar contents of immobile components. Closely associated assemblages of diverse mineralogy suggest that the XMn and XCO2, rather than the physical conditions of metamorphism, are the decisive factors in promoting the observed phase assemblages.

Abstract:
В чрезвычайной ситуации государственной самоизоляции актуализируется вопросы продовольственной безопасности  ценового паритета калорийности продуктов питания. В исследовании рассмотрена и подтверждена гипотеза о существовании взаимосвязи цены с калорийностью продовольствия как ценового паритета. На основе методов эконометрики и энергетического подхода, данных Росстат за 1998-2017 гг. определены цены и калорийности по видам продовольствия. Выявлен линейный характер годового прироста цены калории при стабильном ценовом паритете. Установлены среднегодовые темпы прироста цены потреблённого продовольствия  1,77 руб./Мкал к произведённому 0,38 руб./Мкал (отношение 4,66:1), средняя цена импортной калории  1,24 USD/Мкал, экспортной 0,16 USD/Мкал (отношение 7,75:1). Импортозамещение как основное направление улучшения ценового паритета обеспечит продовольственную безопасность в чрезвычайной ситуации. In the emergency situation of the state self-isolation food security issues – caloric food price parity - are brought up to date. The level of food prices can be a kind of the regulator for planning, organizing and managing the optimal calorie intake by the population. The paper suggests the existence of a function between price and calorie content (number of calories); and the hypothesis on availability of the caloric food price parity was considered and tested. To study the hypothesis, the following objectives were developed and consistently solved: determining the prices and parity of calories produced and consumed; determination of prices and parities of exported and imported calories. Based on the econometric methods and energy approach, as well as on the Rosstat data for the period of 1990-2017 and the Russian Customs data on food product balances and its prices, the wellknown calorie standards for food products, the hypothesis of the investigation was confirmed. The linear nature of the annual increase in the price of calories at the stable price parity was defined. It was found that the average annual growth rate of the consumed food price was 1.77 rubles/Mcal to the produced 0.38 rubles/Mcal (ratio 4.66: 1), the average price of the imported calories was 1.24 USD / Mcal and that of the exported calories was 0.16 USD / Mcal ( ratio 7.75: 1). Import substitution as the main trend for improving the price parity will ensure food security in an emergency situation.

Abstract:
A new low density mineral material has been synthesized via a simple, flexible, cheap and easy to control process. This material is a synthetic carbonate produced by carbonation of a solid phase composed of a calcic part and a magnesian part. Typically, its production process includes the calcination of a raw dolomite (general formula CaCO3.MgCO3) into the oxide form, followed by an at least partial hydration of this oxide and a subsequent carbonation step. This process is thus close to the well-known process used for the production of Precipitated Calcium Carbonate (PCC), a common filler and pigment in plastic, paper and rubber, except that the raw material is a dolomite instead of a limestone. It has to be pointed out that flue gases from different industries can be used as a source of CO2 for the carbonation. Many parameters have been studied, such as the hydration conditions or the carbonation conditions, allowing the production of a whole range of products. The products obtained via this process are composed of a calcic part, mainly as calcite and aragonite (CaCO3), and a magnesium containing part, mainly as hydromagnesite (4MgCO3.Mg (OH)2.4H2O). Compared to standard PCC, this material has a particularly low density (100-250 kg/m3 instead of 300-600 kg/m3 for standard PCC), a rather high BET specific surface area (15-35 m2/g instead of 4-15 m2/g for standard PCC) and a specific particle morphology and structure. The particles are indeed commonly spherical particles composed of a core of calcite/aragonite covered by a layer of hydromagnesite. This structure can be described as a core-shell structure. Due to these special features, this product could be used in multiple applications, such as raw material for the manufacture of insulation material, flame retardant, filler in plastics, paints, paper, rubber, and many more.

Abstract:
In questo lavoro di tesi è stato utilizzato il software dinamico commerciale TRNSYS 17 per realizzare una analisi di dettaglio del comportamento energetico di impianti di riscaldamento ibridi basati sull’uso di una caldaia abbinata ad una pompa di calore aria/acqua. Sono state analizzate diverse soluzioni di impianti ibridi bi-energetici a pompa di calore e caldaia, confrontandone le prestazioni con impianto monovalente a pompa di calore, monovalente a caldaia e impianto ibrido monoenergetico a pompa di calore e resistenza elettrica. Ogni sistema edificio-impianto è stato situato in due città differenti per analizzare l’influenza del clima nell’ottimizzazione dell’impianto e nella scelta della soluzione con migliori prestazioni energetiche ed economiche. Le simulazioni sono state effettuate a Bolzano e Trieste in quanto queste città presentano rispettivamente un clima freddo e umido e caldo e secco, come evidenziato dall'analisi dei dati climatici a disposizione del software TRNSYS. Le simulazioni hanno individuato per Bolzano un punto di ottimo per l'SCOP dell'impianto ibrido utilizzando BT=-5°C e Tco=0°C, mentre per Trieste il punto di ottimo è per BT=-3°C e Tco=0°C. Si evince che più il clima è freddo ed umido, più la regolazione della macchina (Tco) deve escludere la pompa di calore dal funzionamento per un numero maggiore di ore della stagione invernale. Il confronto delle prestazioni energetiche ed economiche tra i vari sistemi di generazione ha evidenziato come i sistemi ibridi pompa di calore e caldaia riescano a raggiungere sia a Bolzano sia a Trieste le migliori performance energetiche, ottenendo gli SCOP più alti. Il risparmio sui costi di esercizio ottenibile dall'utilizzo dell'ibrido però non è sufficiente a ripagare l'investimento iniziale molto alto. Per Bolzano il VAN più basso è raggiunto dal sistema solo caldaia, a Trieste il VAN più basso è raggiunto dal sistema ibrido pompa di calore e resistenza elettrica.

Abstract:
Questa tesi si propone di presentare i principali risultati riguardanti l'equazione del calore. In primo luogo si introduce l'equazione di diffusione, enfatizzando tra le principali proprietà delle soluzioni il principio di sovrapposizione e l'invarianza rispetto alle dilatazioni paraboliche. Queste proprietà verranno utilizzate per costruire la soluzione classica del problema di Cauchy-Dirichlet e la soluzione fondamentale a partire dall'equazione del calore in forma omogenea. Segue un approfondimento sulla legge fondamentale di conduzione del calore, da cui si ricava che l'equazione di diffusione rappresenta un modello matematico per descrivere l'evoluzione nel tempo della temperatura di un corpo rigido. La trattazione prosegue focalizzandosi sullo studio e risoluzione, in senso classico, del problema di Cauchy-Dirichlet per la sbarra omogenea con dato iniziale C^1, sfruttando, in particolare, l'analisi alla base degli sviluppi in serie di Fourier. Successivamente, vengono riportati i risultati generali ottenuti in dimensione n>=1. Tra questi, viene dedotta l'unicità della soluzione del problema di Cauchy-Dirichlet, tramite il principio di massimo debole, e per problemi misti, tramite il principio di Hopf. Infine, si affronta il problema di Cauchy omogeneo globale con dato iniziale continuo e si dimostrano per la soluzione classica: l'esistenza, costruendo la soluzione fondamentale, e l'unicità, introducendo una stima di crescita esponenziale.

Abstract:
L'obiettivo di questa tesi è lo studio dell'equazione del calore. Come accade per molti fenomeni fisici, anche per la diffusione del calore risulta utile trovare un modello matematico che lo descriva in modo fedele e che ne riassuma le principali caratteristiche. Questo modello, nel caso della diffusione del calore assume la forma di un'equazione alle derivate parziali del secondo ordine, chiamata equazione del calore. Nel primo capitolo di questa tesi vedremo come nasce il modello per la diffusione del calore. Nel capitolo 2 definiremo l'equazione del calore e la soluzione fondamentale, che utilizzeremo poi per ricavare la soluzione del problema di Cauchy omogeneo e non omogeneo. Successivamente ci occuperemo di individuare le formule di media per le funzioni caloriche. Nel capitolo 3 vedremo il principio di massimo debole e l'unicità della soluzione, che ne è una diretta conseguenza. Inoltre proveremo un risultato più preciso, il principio di massimo forte. Nell'ultimo capitolo torneranno utili le formule di media viste nel capitolo 2, grazie a esse enunceremo e dimostreremo la disuguaglianza di Harnack. Infine, servendoci di quest'ultima, proveremo il Teorema di Liouville per le funzioni caloriche.

Di seguito si deduce la soluzione fondamentale dell'operatore H evidenziandone alcune importanti proprietà. Si procede, poi, con l'introduzione dell'Identità di Green per l'operatore del calore e da questa si ricava la formula di media per le funzioni caloriche. Grazie a tale formula di media si evidenzia una cruciale proprietà delle funzioni caloriche: la loro regolarità C-infinito. Di seguito si deduce un'espressione migliorata per la formula di media calorica avente come vantaggio quello di avere un nucleo limitato. Si procede, quindi, mostrando alcune conseguenze dell'espressione migliorata dimostrata: si ricava, infatti, in modo diretto la disuguaglianza di Harnack e il principio di massimo forte. L'elaborato procede, poi, con lo studio del problema di Cauchy relativo all'operatore del calore. Infine si analizzano i teoremi di Liouville per le funzioni caloriche.

Abstract:
Cada cop més evidencies suggereixen que els astròcits participen en les altes funcions cerebrals, controlant des de la transmissió sinàptica fins a les ones cerebrals globals i els processos d’aprenentatge i memòria. Diferents mecanismes han sigut proposats com a responsables d’aquests processos mediats per astròcits, entre ells, l’alliberació de gliotransmissors a partir de les senyals de calci així com la de lactat semblen els principals efectors. L’existència d’aquest control de les funcions cerebrals per part dels astròcits suggereix que aquestes cèl·lules poden regular les funcions cerebrals en resposta a experiència tan com les neurones, constituint el fenomen de plasticitat astrocitària. En neurones s’ha demostrat que el conegut factor de transcripció CREB, coordina les plasticitats sinàptica i intrínseca. El fet que, en astròcits, l’activació de CREB també està regulada per activitat cerebral, situa aquest factor de transcripció com a la diana ideal per promoure canvis dependents d’activitat en astròcits. En aquesta tesi hem analitzat l’efecte de l’activació de la transcripció depenent de CREB en astròcits, centrant-nos en l’excitabilitat del calci i en el metabolisme d’aquestes cèl·lules. Hem demostrat que l’activació de la transcripció depenent de CREB redueix les senyals citosòliques de calci a través del mitocondri a la vegada que augmenta l’alliberació de lactat, dos canvis que poden tenir impacte en la transmissió sinàptica. Una altra contribució important d’aquest estudi es l’anàlisi molecular dels mitocondris dels astròcits, que ha revelat que aquestes cèl·lules poden utilitzar metabòlits que no són glucosa, com ara àcids grassos, per respondre a les necessitats metabòliques energètiques. Els nostres resultats estableixen el CREB en astròcits con un eix de la plasticitat astrocitària i revelen la interacció entre la plasticitat i el metabolisme energètic en astròcits. Aquests descobriments constitueixen un avenç mecanístic i conceptual en el coneixement de la biologia dels astròcits i com aquestes cèl·lules poden controlar l’aprenentatge i la memòria.
An increasing body of evidence suggests that astrocytes participate in higher-brain functions, controlling from synaptic transmission to global brain waves and learning and memory processes. Different mechanisms have been proposed to mediate these astrocyte-dependent processes, astrocytic lactate release and calcium-dependent gliotransmission being the main known effectors. The existence of control of brain functions by astrocytes suggests that astrocytes may shape brain functions in response to experience as much as neurons, thus constituting the phenomenon of astrocyte plasticity. In neurons, the transcription factor CREB is the best known coordinator of synaptic and intrinsic plasticity. The fact that, in astrocytes, CREB activation is also activity-dependent, positions CREB as an ideal target to promote plasticity-related changes in astrocytes, too. In this thesis, we have analyzed the effect of the activation of CREB-dependent transcription in astrocytes, specifically regarding calcium signals and metabolism. We have demonstrated that activation of CREB-dependent transcription reduces cytosolic calcium events via mitochondria and increases in lactate release, which may have impact on synaptic transmission. An important contribution of the study is the molecular analysis of astrocytic mitochondria, which has revealed that astrocytes may use fuels other than glucose such as fatty acids to meet basic energy metabolic demands. Taken together, our results establish astrocytic CREB as a hub in astrocyte-plasticity and shed light on the interplay between plasticity and energy metabolism in astrocytes; these findings constitute a conceptual and mechanistic advance in the knowledge of astrocytic biology and how these cells may control learning and memory.

Abstract:
In this dissertation I have created and applied a parametric model for bulk carbonate materials. The new empirical model for carbonates is stable for a wide range of carbonate structures and reproduces experimental results with reasonable accuracy. To study the surface of calcite the ab initio code SIESTA has been used. New implementation has been introduced into the SIESTA code to allow the calculation of effective charges using the modern theory of polarisation. Using these charges the calculation of the long range electrostatic effects, which are removed by the zero electric field boundary conditions, have been introduced into the phonon methodology, reproducing the LO-TO splitting within the calculated phonon modes near the F-point. Furthermore the effective charges have been used in the calculation of the infrared intensity for each phonon mode. The SIESTA implementation of DFT relies upon the evaluation of electron density on a real-space grid. Such discretization of the real-space integrals introduces an oscillatory error in the energy and forces, with the periodicity of the real-space grid. A method for reducing this error has been introduced. The SIESTA code with the new methodology has been used to study bulk calcite, {211} calcite surface and the interaction of water with the {211} sur­face. The structure and phonon frequencies for the bulk match well with experimental values. The {211} surface has been calculated showing the response of the crystal in both distortion of the ion position and the electronic configuration. Surface relaxations and phonon frequencies show no symmetry breaking reconstruction of the calcite {211} surface. Calculation of the interaction of water molecules with the {211} surface predicts the optimum position for water on the surface.

Il etait l'homme de beaucoup le plus digne de la confiance de muhammad, et le confident de ses pensees les plus intimes. Ali est une personnalite universellement reconnue. On peut meme dire qu'aucune autre n'a fait l'objet de tant de discussion et de debats. Il fut source d'inspiration et d'enseignement pour beaucoup de mouvements revolutionnaires, politiques, spirituels et philosophiques. Il vivait dans un monde completement morcele et fragmentaire. Il a demande aux musulmans de vivre et de cooperer autrement ; qu'ils observent le monde sans projeter leurs convictions personnelles, leurs sentiments claniques, afin d'observer clairement. Dans cette these, nous avons essaye d'etudier la personne de ali, qui, au moins pendant une periode importante de sa vie fut profondement, sincerement religieux (imam) mais aussi homme politique (calife). Ce n'etait pas la deux plans separes, mais deux aspects d'une personnalite globale, aspects qui ne peuvent se distinguer que par l'analyse.

Abstract:
Newer sheet alloys (such as Al, Mg, and advanced high strength steels) are considered for automotive body panels and structural parts to achieve lightweight construction. However, in addition to issues with their limited formability and high springback, tribological conditions due to increased surface hardness and higher work hardening effect necessitate the use of improved alternative die materials, coatings, lubricants to minimize the wear-related issues in stamping of such lightweight materials. This study aims to investigate and compare the wear performances of seven (7) different die materials (AISI D2, Vanadis 4, Vancron 40, K340 ISODUR, Caldie, Carmo, 0050A) using a newly developed wear testing method and device. We used DP600 sheets in the tests. Our results showed that almost all of the recently developed specially-alloyed die materials demonstrated higher wear resistance performance when compared with the performance of AISI D2 die material.

In ASME 2010 13th International Conference on Environmental Remediation and Radioactive Waste Management. ASMEDC, 2010. http://dx.doi.org/10.1115/icem2010-40070.

Abstract:
This study aimed to develop a methodology for assessing the evolution of the long-term groundwater system, using fracture-filling calcite. Fracture-filling calcite mineralization in deep (to ca. 1000 m) granitic rocks in Mizunami area, Japan, was studied. Four generations (I to IV) of calcite precipitation can be differentiated based on their paragenetic relationships, morphological and isotopic characteristics. Carbon and oxygen isotopic ratios suggest that the Calcite I is of hydrothermal origin. On the other hand, Calcite II, IV and III were precipitated from freshwater and marine water, respectively. The Mizunami Group strata (Tertiary), which overly the basement Toki granite (Cretaceous), were initially deposited in a lacustrine environment but later became marine. Lacustrine conditions were re-established during the deposition of the upper Seto Group (Quaternary). It is suggested that both of deposition of the marine upper part of the Mizunami Group and the precipitation of Calcite III were possibly related to the same transgression event. This was followed by the precipitation of Calcite IV during subsequent fresh water flushing of the earlier marine groundwater. In summary, integrated morphological, mineralogical, microchemical and isotopic analysis of multilayered calcite fracture mineralization provides valuable information to evaluate the long-term evolution of groundwater system.

In ASME 2012 Pressure Vessels and Piping Conference. American Society of Mechanical Engineers, 2012. http://dx.doi.org/10.1115/pvp2012-78150.

Full text
Abstract:
The Calcine Disposition Project (CDP) of the Idaho Cleanup Project (ICP) has the responsibility to retrieve, treat, and dispose of the calcine stored at the Idaho Nuclear Technology and Engineering Center (INTEC) located at the Idaho National Laboratory. Calcine is the granular product of thermally treating, or calcining liquid high-level waste (HLW) that was produced at INTEC during the reprocessing of spent nuclear fuel (SNF) to recover uranium. The CDP is currently designing the Hot Isostatic Pressure (HIP) treatment for the calcine to provide monolithic, glass-ceramic waste form suitable for transport and disposition outside of Idaho by 2035 in compliance with the Idaho Settlement Agreement. The HIP process has been used by industry since its invention, by Battelle Institute, in 1955. Hot isostatic pressing can be used for upgrading castings, densifying pre-sintered components, and consolidate powders. It involves the simultaneous application of a high pressure and temperature in a specially constructed vessel. The pressure is applied on all sides with a gas (usually inert) and, so, is isostatic. The CDP will use this treatment process (10,000 psi at 1,150 C) to combine physically and chemically a mixture of calcine and granular additives into a non leachable waste-form. The HIP process for calcine involves filling a metal can with calcine and additives, heating and evacuating the can to remove volatiles, sealing the can under vacuum, and placing the can within the HIP machine for treatment. Although the HIP process has been in use for over 50 years it has not been applied in large scale radioactive service. Challenges with retrofitting such a system for Calcine treatment include 1) filling and sealing the HIP can cleanly and remotely, 2) remotely loading and unloading the HIP machine, and 3) performing maintenance and repair on a 300 ton, hydraulically actuated machine in a highly radioactive hot cell environment. In this article, a systems engineering approach, including use of industry-proven design-for-quality tools and quantitative assessment techniques is summarized. Discussions on how these techniques were used to improve high-consequence risk management and more effectively apply failure mode, RAMI, and time and motion analyses at the earliest possible stages of design are provided.
