Streszczenie:

The boron isotope composition of calcium carbonate shells of marine organisms has the unique potential to record surface ocean pH, allowing the calculation of atmospheric pCO2 due to the established relationship between pH and the partial pressure of (atmospheric) CO2 (pCO2). This “paleo-pH meter” allows scientists to produce a record of the natural fluctuations of atmospheric pCO2 over geologic time, which will help us better understand the impacts of the recent anthropogenic addition of CO2 to Earth's atmosphere. Towards this end, a tremendous effort to understand the systematics of boron uptake in marine carbonates is underway. Here, we review the potential of boron isotopes to constrain ocean pH and, thus, atmospheric pCO2.

Streszczenie:

Currently all nuclear power plants with VVER -reactors used data measuring systems called a Boron Concentration Meter (NAR). They are necessary for the boron control implementation. NAR consists of sensors and auxiliary devices, and it includes the device of storage and data processing (UNO). Both the rapid evolution of computer architectures, and associated microprocessor hardware updates in the electronics market create a necessity of a new device development. The main design goals both are to optimize the hardware solutions and to use a new software and algorithmic capabilities. However, another development goal is not only the upgrading of circuitry and software, but the optimization of calibration process in the NAR and testing it.

Streszczenie:

Materials with high thermal conductivity (κ) are of technological importance and fundamental interest. We grew cubic boron nitride (cBN) crystals with controlled abundance of boron isotopes and measured κ greater than 1600 watts per meter-kelvin at room temperature in samples with enriched 10B or 11B. In comparison, we found that the isotope enhancement of κ is considerably lower for boron phosphide and boron arsenide as the identical isotopic mass disorder becomes increasingly invisible to phonons. The ultrahigh κ in conjunction with its wide bandgap (6.2 electron volts) makes cBN a promising material for microelectronics thermal management, high-power electronics, and optoelectronics applications.

The chemical reaction between water and frit surface was determined using pH meter, ICP-MS, zeta-potential analyzer and FT-IR. With increasing the content of barium and boron of glass composition, the difference of water pH increased with different glass systems. During wet milling in aqueous solution, boron and barium of glasses dissolved. The values of zeta potential of lead and bismate frits were negative in water solution. Based on the results, when wet milling is used in water solution, the contents of barium and boron in a glass should be less than 10mol%.

Streszczenie:

Pendant l'exploitation d'un Réacteur à Eau Pressurisée (REP), la maîtrise de la teneur en bore constitue un enjeu de sûreté majeur. En raison de sa section efficace de capture significative pour les neutrons thermiques, le bore-10 (¹⁰B) est injecté dans le fluide primaire afin de compenser les variations de la réactivité résultant de l'usure du combustible et des oscillations xénon. Un dispositif appelé "boremètre" est installé pour surveiller en continu la teneur en bore durant l'exploitation des tranches. Le fonctionnement du boremètre repose sur la technique de mesure dite par "atténuation et absorption neutronique". Une source de neutrons (de type Am-Be ou ²⁵²Cf) émet des neutrons rapides qui interagissent avec le fluide boré. Après thermalisation, une partie de ces neutrons est capturée par le ¹⁰B selon la réaction (n, α) tandis que le reste est mesuré par un détecteur de neutrons dédié à cet effet. Ainsi, le taux de comptage mesuré (en coups/s), est représentatif de la teneur en bore contenue dans le fluide (en ppm). Une faible concentration en bore entraîne une moindre absorption des neutrons par le fluide, augmentant ainsi le comptage, et inversement. Cette méthode de mesure établit donc une anticorrélation entre la concentration en bore et le comptage mesuré. Le Retour d'EXpérience (REX) concernant la mesure du bore en réacteur, initialement assurée par le boremètre REN (installé au niveau du circuit d'échantillonnage nucléaire), permet de dégager des anomalies fréquentes induisant des indisponibilités récurrentes. La non-redondance de cette ligne de mesure a conduit l'Autorité de Sûreté Nucléaire (ASN) à prescrire l'installation d'un dispositif redondant sur la ligne de décharge du circuit de contrôle chimique et volumétrique : le boremètre RCV. La mesure de la concentration en bore en réacteur s'avère complexe pour deux raisons principales. Tout d'abord, il est nécessaire de quantifier des faibles variations de cette concentration, de l'ordre du ppm. Ensuite, les variations des paramètres thermohydrauliques, comme la température et le débit, induisent des perturbations de la mesure. L'objectif principal de cette thèse est d'élucider les phénomènes physiques régissant la mesure du bore en réacteur, dans le but de concevoir un boremètre innovant offrant une performance de mesure optimisée en temps réel. Pour atteindre cet objectif, trois axes de recherche ont été explorés. Le premier axe porte sur l'étude et l'optimisation du boremètre RCV. Le deuxième axe se concentre sur la compréhension des phénomènes physiques influençant la mesure du bore. Enfin, le troisième axe examine la faisabilité de l'implémentation d'une nouvelle instrumentation de type boremètre au niveau du circuit primaire (RCP). Ce dernier volet, bien que présentant de nombreux défis techniques, a été motivé par les avantages offerts par cet emplacement, notamment une mesure en temps réel et une détection plus rapide des situations accidentelles influençant la dynamique du bore. L'exemple d'une dilution hétérogène inhérente à un Accident de Perte de Réfrigérant Primaire (APRP) sert de cas d'application pour la démonstration de sûreté
During the operation of a Pressurized Water Reactor (PWR), monitoring boron concentration is of paramount safety importance. Due to its significant neutron capture cross section for thermal neutrons, boron-10 (¹⁰B) is injected into the primary coolant to compensate for reactivity variations resulting from fuel burnup and xenon oscillations. A device called "boron meter" is thus necessary to continuously monitor boron concentration during reactor operation. Boron meter operates based on the "neutron attenuation and absorption" measurement technique. A neutron source (such as Am-Be or ²⁵²Cf) emits fast neutrons that interact with the borated coolant. After thermalization, a portion of these neutrons is captured by ¹⁰B through the (n, α) reaction, while the remaining neutrons are measured by a dedicated neutron detector. Thus, the measured count rate (in counts/s) is indicative of the boron concentration (in ppm). A low boron concentration results in fewer neutrons being absorbed by the fluid, thereby increasing the count rate, and vice versa. This measurement method therefore establishes an anticorrelation between boron concentration and the measured count rate. Operating experience feedback regarding boron measurement in reactors, initially ensured by the PSS boron meter (installed in the Primary Sampling System), has revealed frequent anomalies leading to recurrent unavailability. The lack of redundancy in this measurement line led the French Nuclear Safety Authority (ASN) to prescribe the installation of a redundant device on the discharge line of the Chemical and Volume Control System: the CVCS boron meter. Boron concentration measurement in reactors is complex for two main reasons. First, it is necessary to quantify low concentration variations, in the order of ppm. Second, variations in thermal hydraulic parameters, such as temperature and flow rate, induce measurement perturbations. Therefore, the main objective of this thesis is to elucidate the physical phenomena affecting boron measurement in reactors, with the aim of designing an innovative boron meter that offers optimized real-time measurement performance. To achieve this objective, three research areas have been explored. The first area focuses on the study and optimization of the CVCS boron meter. The second area concentrates on understanding the physical phenomena influencing boron measurement. Finally, the third area examines the feasibility of implementing a new boron meter instrumentation at the Reactor Coolant System (RCS). This last aspect, despite presenting numerous technical challenges, has been motivated by the significant advantages offered by this location, including real-time measurement and faster detection of accidental situations affecting boron dynamics. The example of heterogeneous dilution inherent to a Loss-of-Coolant Accident (LOCA) serves as a safety demonstration application

Uppsatsen undersöker Twilight, skriven av Stephenie Meyer, utifrån de intersektionella kategorierna ålder, kön och klass i förhållande till relationen mellan protagonisterna Bella och Edward. Syftet med undersökningen är att ta reda på hur ålder, kön och klass påverkar relationen. Vidare syftar uppsatsen till att undersöka hur ålder, kön och klass påverkar maktförhållandet i relationen utifrån Foucaults maktteori. Resultatet visar att ålder, kön och klass genomgående i Twilight försätter Bella i en underordnad maktposition, med några få undantag. Många normer gällande de tre kategorierna reproduceras i relationen mellan Bella och Edward, vilket i sin tur ger upphov till en maktobalans. Med anledning av detta resultat bör Twilight läsas kritiskt ur ett intersektionellt perspektiv, men kan med fördel användas i klassammanhang för att belysa och ifrågasätta normer rörande t. ex. ålder, kön och klass.

Milton’s presence in Icelandic letters is largely limited to Jón Þorláksson’s translation of Paradise Lost, the first books of which were published in 1794–6. This translation is arguably one of the stepping stones in Icelandic literary history, emerging at a critical crossing point of Icelandic literary heritage, religious literacy, and a developing secular culture born of the Enlightenment and quickly heading towards Romanticism. This chapter analyses the historical and cultural context of Þorláksson’s enterprise; why he translated Milton through intermediary translations (Danish and German); why and with what results he opted for the Icelandic fornyrðislag metre, apparently so different from Milton’s blank verse; and how he actively delved into the language and material of Norse myths and medieval Icelandic literature in coming to terms with Milton’s classical and biblical discourse—in a translational dialogue that proved vital for Þorláksson’s successors, the Romantic poets who are often seen as rejuvenating Icelandic literature.

This single-volume book provides students, educators, and politicians with an update to the classic Carey McWilliams work North From Mexico. It provides up-to-date information on the Chicano experience and the emergent social dynamics in the United States as a result of Mexican immigration. Carey McWilliam's North From Mexico, first published in 1948, is a classic survey of Chicano history. Now fully updated by Alma M. García to cover the period from 1990 to the present, McWilliams's quintessential book explores all aspects of Chicano/a experiences in the United States, including employment, family, immigration policy, language issues, and other cultural, political, and social issues. The volume builds on the landmark work and also provides relevant up-to-date content to the 1990 edition revised by Matt S. Meier, which added coverage of the key period in Chicano history from the postwar period through to the late 1980s. As the largest group of immigrants in the United States, representing more than a quarter of foreign-born individuals in the United States, Mexican immigrants have had and will continue to have a tremendous impact on the culture and society of the United States as a whole. This freshly updated edition of North from Mexico addresses the changing demographic trends within Mexican immigrant communities and their implications for the country; analyzes key immigration policies such as the Immigration Act of 1990 and California's Proposition 187, with specific emphasis on the political mobilization that has developed within Mexican American immigrant communities; and describes the development of immigration reform as well as community organizations and electoral politics. The book contains new chapters that examine recent trends in Mexican immigration to the United States and identify the impact on politics and society of Mexican immigrants and later generations of U.S.-born Mexican Americans. The appendices provide readers and researchers with current immigration figures and information regarding today's socieconomic conditions for Mexican Americans.

Ribbon beams of heavy ions have advantages over cylindrical beams, including higher space-charge limits. History of use goes from Calutrons, Freeman and Bernas ion sources, to the first ion implanters in the 1970s. In the 1990s, 300 mm uniform parallel mass-analyzed ribbon beams were developed to enable precise doping by mechanically scanning a substrate through the ion beam in one dimension. Ion species included the primary dopants boron, phosphorus and arsenic, but many others are also used. Such sources can produce currents of heavy ions with linear current densities at the source of the order of 10 mA/cm, but these sources are limited in the beam breadth they can produce. Broader beams are used for flat-panel display manufacture. A new linear source design combines a modified Penning trap with magnetic cusp confinement system, allowing extension of linear sources to meter scale beam breadths, maintaining around 10 mA/cm linear current density. Magnetic analysis of such beams has required new developments because the weight of conventional dipole magnets increases very steeply as the pole gap is increased. A new magnetic configuration has been developed to address this issue, reducing the potential weight of meter-scale analyzed systems by an order of magnitude.

Nano science is an integrative field that comprises chemical science, physics, biology, and engineering fields and deals with their synthesis, properties, and applicability to future trends. Nanotechnology mainly includes particles having sizes at the nano scale (one billionth of a meter) and examining their physical and chemical properties at the nano scale. The properties of nano materials differ considerably from those of bulk materials. In this chapter, we have listed the applications of nano materials in various areas as reported by the scientific community. The nano particles exhibit applicability in the food industry as packaging material, electronics items such as chips, devices, and displays, and in the medicinal field to detect cancer and its treatment. Another interesting application is in tissue engineering, remediation of pollution, and in agricultural areas as nano pesticides and nano fertilizers. The applications of nanotechnology in various sectors are tremendously expanding, resulting in a rise in the global market for nano materials. With the help of nanotechnology, everyday products become more functional and efficient, which enhances our quality of life.

Abstract To determine if exposure to electromagnetic radiation is associated with the risk of a birth defect. More specifically, does a newborn infant whose mother lives near high-voltage power lines have an increased risk of a congenital anomaly? DATA Of the infants born in the east-central region of France (1988-1991) and observed during the first year of life, 118 had major congenital anomalies. Each of these 118 infants were matched to two randomly selected controls who were of the same gender and born approximately on the same date in the same municipality. For all 354 study subjects, the distance from their mother’s residence (home/apartment during pregnancy) was measured to the nearest 225 or 400 kilovolt high-voltage power line. These data were derived entirely from birth records and detailed maps.

Johann Wolfgang Döbereiner (“Law of Triads”), John Newlands (“Law of Octaves”), Julius Lothar Meyer and others preceded Dmitri Mendeleev's publication of his first periodic table in 1869. Several Döbereiner and Meyer sites are noted. Mendeleev is regarded as the prime originator of the table because he predicted the existence of three then unknown elements that he called eka-boron, eka-aluminum and eka-silicon. These elements (gallium, scandium and germanium) were subsequently discovered by Paul Émile Lecoq de Boisbaudran (1875), Lars Frederick Nilson and Per Teodor Clève (1879), and Clemens Winkler (1886), respectively. We visit the de Boisbaudran sites in Cognac, France and two striking sites in Freiburg, Germany including the Clemens Winkler Memorial and the Clemens Winkler Collection. Mendeleev also accurately predicted the properties of his eka-elements and when these were found to be astonishingly accurate, he became world-famous. We explore the D. I. Mendeleev Museum and Archives and the Museum of Metrology in St. Petersburg as well as several places in Mendeleev's native Siberia. We finish the chapter with sites related to Mikhail Lomonosov, the father of Russian science who goes largely unrecognized in the history of science. This includes the M. V. Lomonosov Museum in the Kunstkamera.

Abstract This is a lullaby, composed for Dhomhnaill, or Donald, Gorm of Sleat in Skye by his nurse. Curiously, it is The only lullaby included in this collection: while it is certain that early modem women sang to Their babies, such compositions are remarkably hard to find in written form. The nurse looks forward to a future in which The infant Dhomhnaill will display all The virtues of a Gaelic hero, The inheritor of an ancient, warrior culture. By The time Dhomhnaill was born, Irish and Scottish Gaelic singers had celebrated Cu Chulainn, Finn, Osein (Ossian), and Oscar for a thousand years. But while The contents of The nurse’s song is based on The tropes of professional, bardic praise poetry, she does not use The complex, classical bardic metres, but a simple folksong metre, in whch lines are linked by assonance in The penultimate syllable.

The paper represents the effects of the drive-in process parameters on the residual stress profile of the p+ silicon film quantitatively. Since the residual stress profile is not uniform along the direction normal to the surface, the residual stress is assumed to be a polynomial function of the depth. All of the coefficients of the polynomial are determined from the deflections of cantilevers and the displacement of a rotating beam structure, which are measured with a surface profiler meter and a microscope. As the drive-in temperature or the drive-in time increases, the boron concentration decreases and the magnitude of the average residual tensile stress decreases. Also, near the surface of the p+ film the residual tensile stress is transformed into the residual compressive stress and its magnitude increases. The correlation coefficients between the residual stress profiles and the simulated boron concentration are calculated. As the drive-in time and temperature increase, all correlation coefficients become close to 1, and the boron concentration profiles after the drive-in process are similar to the stress profiles. Also, the lattice contractions of test wafers are measured by HRXRD (High Resolution X-Ray Diffractometry).

Submesoscale cold-core (T < 0°C) eddies were observed near the shelf break in Peter the Great Bay of the East/Japan Sea in March 2010. The observations were carried out at the moored automatic mobile profiler Aqualog station. The profiling was as frequent as every hour allowing us to obtain data with high temporal resolution. Aqualog delivered vertical profiles of ocean current velocity, acoustic backscatter at 2 MHz, temperature, and salinity between the depths of 20 m and 105 m. Below the profiling range, the InterOcean S4 current meter with temperature and salinity sensors was mounted on the mooring line. Above the profiling range, the RBR XR420 CTD logger with dissolved oxygen, chlorophyll-a fluorescence, and turbidity sensors was also mounted on the mooring line. Additionally we used the data of ship-born CTD casts, the satellite-born imagery and scatterometery, and the coastal weather station records. The data analysis suggests that the cold-core submesoscale eddies play an important role in supplying the densest water (σθ > 27.24 kg/m3) from the northern part of Peter the Great Bay to the shelf break zone where it cascades downward into the deep northern basin of the Sea. The volume of the densest water in an eddy, according to our rough estimate, is 0.5-1 km³. At the sea shelf, the densest water is richer in oxygen by 0.4 ml/l than surrounding water. It also contains much more suspended particles brought by the rivers.

Abstract A large fraction of HLW glass readily precipitates spinel. The presence of solid particles, including spinel crystals, is undesirable in a high-level waste (HLW) glass melter because the settling of solids can disrupt melter operation and shorten melter lifetime. Spinel formation in the melter can be reduced by lowering waste loading. When formulating HLW glass to maximize waste loading (thus minimizing the cost), the settling of insolubles must be considered. The rate of nucleation, growth, and dissolution of spinel crystals in a molten HLW glass was measured as a function of temperature and the presence of nucleation agents, such as noble metals. The mass transfer coefficient was calculated using the Hixson-Crowell model and expressed as an Arrhenius function of temperature that was identical for both crystal growth and crystal dissolution. The Stokes law for hindered settling and the Hixson-Crowell equation for crystal growth and dissolution were chosen as a convenient representation of spinel behavior for mathematical models of HLW glass melters. Levich’s analysis of the dissolution or growth of falling particles was used to estimate the effective diffusion coefficient (D) and the concentration-boundary-layer thickness (δ) around growing and dissolving crystals. The estimated values were in reasonable agreement with the measured concentration profile of Fe at a dissolving spinel crystal at 1200°C, determined with energy dispersive spectroscopy. The D value is comparable to that obtained by Borom and Pask for a sodium disilicate-magnetite couple. The calculated δ value agreed with the concentration distribution of Fe around falling crystals of spinel as imaged by optical microscopy. This methodology, in conjunction with mathematical modeling, provides a basis for developing optimized technology and glass formulation for HLW vitrification.

Abstract The EUREX reprocessing pilot plant, at ENEA Research Centre, Saluggia (VC - Italy), stores 113 m3 of intermediate level liquid waste and 110 m3 of low level liquid waste, originating from the past reprocessing campaigns. Conditioning of the above wastes, for the purpose of final disposal, has been planned in a new installation for the solidification of both intermediate and low level wastes at Saluggia site. The installation, under design, has been named CORA Plant (COnditioning of RAdioactive wastes). Direct Vitrification process using cold crucible melter (CCM) developed by CEA of Marcoule, has been chosen as conditioning technology for a mix of most active wastes and cementation for secondary low level waste produced during vitrification. A boro-silicate glass matrix has been selected with a specific nominal chemical composition adapted to liquid waste matrix. Characterisation work of this specific glass is under progress. CORA has been presented to regulatory authority has a modification of a pilot reprocessing Eurex plant. Vitrification equipment and glass canister interim storage facility of CORA Plant will be housed inside the existing building of Eurex facility properly modified. Cementation unit inside a new building located in a near external yard. A description of the waste management scheme, as well as a brief description of adopted technologies, chemical glass composition and updated schedule of CORA project is presented in this paper.

<div class="section abstract"><div class="htmlview paragraph">The world over has resulted in severe pollution problems. They are classified as air and noise pollution. Air pollution is caused by dispersion of emittents from engine exhaust to the atmosphere at different concentration levels. Similarly, the emission of unwanted sound from engine structure, intake and exhaust are the principal source of noise pollution.</div><div class="htmlview paragraph">In diesel engines structurally, radiated noises have numerous origins. The complexity arises from the fact that the whole engine structure is simultaneously excited by several forces of widely different characteristics. Primary exciting force which is a gas force in the cylinder resulting from the combustion. Secondary exciting forces of considerably different characteristics are generated by the operation slider crank mechanism but related to some primary gas force in some non-linear manner resulting in piston impact, impacts in bearing, impacts in timing gears etc. Force produced in accessories such as valve gear system, fuel injection system etc.</div><div class="htmlview paragraph">In the present study, the structure-born noises are studied by isolating exhaust noise from measurement areas at different moderate loads and speed conditions to see the impact of noise generation of a heavy-duty diesel engine on the test bed. The engine considered was an 80.85 kw multi-cylinder diesel engine on a test bed coupled with a hydraulic dynamo-meter. The engine was manufactured by Tata. The noise was measured at a distance of 1m and 2m at 10 different locations at different load and speed conditions. With this noise contours are plotted to see the behavior of noise emission from engine structure with variation of load and speed.</div><div class="htmlview paragraph">The overall frequency v/s sound pressure level (SPL) graphs were plotted. The impact of the speed of the engine was also studied in the present studies to show the impact of combustion at different speeds on the structural noise emissions.</div><div class="htmlview paragraph">The combined impact of engine noise and load on structural noise and piston slap was also studied.</div></div>
