Advanced functionality for radio analysis in the Offline software framework of the Pierre Auger Observatory

The advent of the Auger Engineering Radio Array (AERA) necessitates the development of a powerful framework for the analysis of radio measurements of cosmic ray air showers. As AERA performs ""radio-hybrid"" measurements of air shower radio emission in coincidence with the surface particle detectors and fluorescence telescopes of the Pierre Auger Observatory, the radio analysis functionality had to be incorporated in the existing hybrid analysis solutions for fluorescence and surface detector data. This goal has been achieved in a natural way by extending the existing Auger Offline software framework with radio functionality. In this article, we lay out the design, highlights and features of the radio extension implemented in the Auger Offline framework. Its functionality has achieved a high degree of sophistication and offers advanced features such as vectorial reconstruction of the electric field, advanced signal processing algorithms, a transparent and efficient handling of FFTs, a very detailed simulation of detector effects, and the read-in of multiple data formats including data from various radio simulation codes. The source code of this radio functionality can be made available to interested parties on request. (C) 2011 Elsevier B.V. All rights reserved.

Anisotropy and chemical composition of ultra-high energy cosmic rays using arrival directions measured by the Pierre Auger Observatory

The Pierre Auger Collaboration has reported. evidence for anisotropy in the distribution of arrival directions of the cosmic rays with energies E > E(th) = 5.5 x 10(19) eV. These show a correlation with the distribution of nearby extragalactic objects, including an apparent excess around the direction of Centaurus A. If the particles responsible for these excesses at E > E(th) are heavy nuclei with charge Z, the proton component of the sources should lead to excesses in the same regions at energies E/Z. We here report the lack of anisotropies in these directions at energies above E(th)/Z (for illustrative values of Z = 6, 13, 26). If the anisotropies above E(th) are due to nuclei with charge Z, and under reasonable assumptions about the acceleration process, these observations imply stringent constraints on the allowed proton fraction at the lower energies.

Search for first harmonic modulation in the right ascension distribution of cosmic rays detected at the Pierre Auger Observatory

We present the results of searches for dipolar-type anisotropies in different energy ranges above 2.5 x 10(17) eV with the surface detector array of the Pierre Auger Observatory, reporting on both the phase and the amplitude measurements of the first harmonic modulation in the right-ascension distribution. Upper limits on the amplitudes are obtained, which provide the most stringent bounds at present, being below 2% at 99% C.L. for EeV energies. We also compare our results to those of previous experiments as well as with some theoretical expectations. (C) 2011 Elsevier B.V. All rights reserved.

The Pierre Auger Observatory scaler mode for the study of solar activity modulation of galactic cosmic rays

Since data-taking began in January 2004, the Pierre Auger Observatory has been recording the count rates of low energy secondary cosmic ray particles for the self-calibration of the ground detectors of its surface detector array. After correcting for atmospheric effects, modulations of galactic cosmic rays due to solar activity and transient events are observed. Temporal variations related with the activity of the heliosphere can be determined with high accuracy due to the high total count rates. In this study, the available data are presented together with an analysis focused on the observation of Forbush decreases, where a strong correlation with neutron monitor data is found.

The exposure of the hybrid detector of the Pierre Auger Observatory

The Pierre Auger Observatory is a detector for ultra-high energy cosmic rays. It consists of a surface array to measure secondary particles at ground level and a fluorescence detector to measure the development of air showers in the atmosphere above the array. The ""hybrid"" detection mode combines the information from the two subsystems. We describe the determination of the hybrid exposure for events observed by the fluorescence telescopes in coincidence with at least one water-Cherenkov detector of the surface array. A detailed knowledge of the time dependence of the detection operations is crucial for an accurate evaluation of the exposure. We discuss the relevance of monitoring data collected during operations, such as the status of the fluorescence detector, background light and atmospheric conditions, that are used in both simulation and reconstruction.

Update on the correlation of the highest energy cosmic rays with nearby extragalactic matter

Data collected by the Pierre Auger Observatory through 31 August 2007 showed evidence for anisotropy in the arrival directions of cosmic rays above the Greisen-Zatsepin-Kuz`min energy threshold, 6 x 10(19) eV. The anisotropy was measured by the fraction of arrival directions that are less than 3.1 degrees from the position of an active galactic nucleus within 75 Mpc (using the Veron-Cetty and Veron 12th catalog). An updated measurement of this fraction is reported here using the arrival directions of cosmic rays recorded above the same energy threshold through 31 December 2009. The number of arrival directions has increased from 27 to 69, allowing a more precise measurement. The correlating fraction is (38(-6)(+7))%, compared with 21% expected for isotropic cosmic rays. This is down from the early estimate of (69-(+11)(13))%. The enlarged set of arrival directions is examined also in relation to other populations of nearby extragalactic objects: galaxies in the 2 Microns All Sky Survey and active galactic nuclei detected in hard X-rays by the Swift Burst Alert Telescope. A celestial region around the position of the radiogalaxy Cen A has the largest excess of arrival directions relative to isotropic expectations. The 2-point autocorrelation function is shown for the enlarged set of arrival directions and compared to the isotropic expectation. (C) 2010 Elsevier B.V. All rights reserved.

A supply chain approach to meat goat industry development

The Victorian goat meat industry is a significant contributor to export earnings, which is derived largely from the harvest of feral goats. The potential for exports of farmed goat meat into Asian product markets is being developed in a supply chain approach with producers, processors, exporters and Asian importers. Producers have been networked in four locations to improve supply capability and participate in production and economic benchmarking. In the absence of an existing market for premium farmed goat meat, a larger group of producers are cooperating with a marketer to develop a niche market in the Asian food service sector. This presents a challenge to the group in developing commercial relationships and playing a role in the marketing of their goat meat.

Razoável duração do processo

O presente trabalho desenvolvido em suas respectivas partes, versa sobre a Razoável Duração do Processo. O tema é deveras amplo pela sua complexidade, magnitude e atualidade. Trata da terminologia do abuso do direito e sua distinção processual, mesmo nas situações configuradoras de uma ilicitude para as quais ainda não existe norma punitiva expressa, respeitados os limites que não constituam ofensa ao princípio do due process of law. Ressalta-se o princípio da proporcionalidade, com proposta de torna-lo mais evidente na distinção com o princípio da razoabilidade quando da análise de seus elementos destacando-se a sua relevância na criação e na aplicação das normas jurídicas, sua natureza independência e supremacia em relação a outros princípios constitucionais com proposta de tal prática pode ser reduzida a níveis razoáveis pela criteriosa aplicação do princípio da proporcionalidade. Finalmente, observa que o abuso do direito tem repercussão direta na morosidade do processo, problema mais agudo na prestação jurisdicional de nosso tempos, e que não basta aprimorar o tecnicismo e a estrutura física do Judiciário para superar o grave problema, sendo indispensável, também, a permanente busca da excelência pessoal de todos do cenário jurídico.

Perceptual maps analysis for organic food consumers in China: a study on Shanghai consumers

Although in Europe and in the USA many studies focus on organic, little is known on the topic in China. This research provides an insight on Shanghai consumers’ perception of organic, aiming at understanding and representing in graphic form the network of mental associations that stems from the organic concept. To acquire, process and aggregate the individual networks it was used the “Brand concept mapping” methodology (Roedder et al., 2006), while the data analysis was carried out also using analytic procedures. The results achieved suggest that organic food is perceived as healthy, safe and costly. Although these attributes are pretty much consistent with the European perception, some relevant differences emerged. First, organic is not necessarily synonymous with natural product in China, also due to a poor translation of the term in the Chinese language that conveys the idea of a manufactured product. Secondly, the organic label has to deal with the competition with the green food label in terms of image and positioning on the market, since they are easily associated and often confused. “Environmental protection” also emerged as relevant association, while the ethical and social values were not mentioned. In conclusion, health care and security concerns are the factors that influence most the food consumption in China (many people are so concerned about food safety that they found it difficult to shop), and the associations “Safe”, “Pure and natural”, “without chemicals” and “healthy” have been identified as the best candidates for leveraging a sound image of organic food .

Perfluoroalkylated substances in food matrices: development of mass spectrometry based analytical methods and preliminary monitoring

Perfluoroalkylated substances are a group of chemicals that have been largely employed during the last 60 years in several applications, widely spreading and accumulating in the environment due to their extreme resistance to degradation. As a consequence, they have been found also in various types of food as well as in drinking water, proving that they can easily reach humans through the diet. The available information concerning their adverse effects on health has recently increased the interest towards these contaminants and highlighted the importance of investigating all the potential sources of human exposure, among which diet was proved to be the most relevant. This need has been underlined by the European Union through Recommendation 2010/161/EU: in this document, Member States were called to monitor their presence of in food, producing accurate estimations of human exposure. The purpose of the research presented in this thesis, which is the result of a partnership between an Italian and a French laboratory, was to develop reliable tools for the analysis of these pollutants in food, to be used for generating data on potentially contaminated matrices. An efficient method based on liquid chromatography-mass spectrometry for the detection of 16 different perfluorinated compounds in milk has been validated in accordance with current European regulation guidelines (2002/657/EC) and is currently under evaluation for ISO 17025 accreditation. The proposed technique was applied to cow, powder and human breast milk samples from Italy and France to produce a preliminary monitoring on the presence of these contaminants. In accordance with the above mentioned European Recommendation, this project led also to the development of a promising technique for the quantification of some precursors of these substances in fish. This method showed extremely satisfying performances in terms of linearity and limits of detection, and will be useful for future surveys.

Contributi della Geomatica nella salvaguardia e gestione dei Beni Culturali

Il territorio italiano presenta una grandissima ricchezza nel campo dei Beni Culturali, sia mobili che immobili; si tratta di un patrimonio di grande importanza che va gestito e tutelato nel migliore dei modi e con strumenti adeguati, anche in relazione ai problemi ad esso legati in termini di manutenzione e di salvaguardia dai fattori di rischio a cui può essere esposto. Per una buona conoscenza del Patrimonio Culturale, è fondamentale un’acquisizione preliminare di informazioni condotte in modo sistematico e unitario, che siano diffuse ed organiche, ma anche utili ad una valutazione preventiva e ad una successiva programmazione degli interventi di restauro di tipo conservativo. In questo ambito, l'impiego delle tecniche e tecnologie geomatiche nel campo dei Beni Culturali, può fornire un valido contributo, che va dalla catalogazione e documentazione del bene culturale al suo controllo e monitoraggio. Oggigiorno il crescente sviluppo di nuove tecnologie digitali, accompagnato dai notevoli passi avanti compiuti dalle discipline della geomatica (in primo luogo topografiche e fotogrammetriche), rende possibile una efficace integrazione tra varie tecniche, favorita anche dalla diffusione di soluzioni per l’interscambio dati e per la comunicazione tra differenti dispositivi. Lo studio oggetto della presente tesi si propone, di approfondire gli aspetti legati all’uso delle tecniche e tecnologie della Geomatica, per mettere in risalto le condizioni di un bene ed il suo stato di degrado. Per la gestione e la salvaguardia di un bene culturale , si presenta il SIT Carta del Rischio che evidenzia le pericolosità legate al patrimonio, e come esse sommate alla vulnerabilità di un singolo bene, contribuiscano all’individuazione del grado di rischio. di approfondire gli aspetti legati all’uso delle tecniche e tecnologie delle Geomatica, per mettere in risalto le condizioni di un bene ed il suo stato di degrado.

La fondazione della citta di odessa: Il ruolo determinante degli italiani.

Durante l'Impero di Caterina II di Russia, nel 1794 gli artisti, architetti, pittori, operai italiani furono invitati a fondare la città di Odessa. Avviarono un processo di colonizzazione basato sulla divulgazione della cultura italiana, della sua cucina, della sua architettura, e gettando le fondamenta per un'economia marittima e portuale basata su import-export in tutta Europa. In questa ricerca si analizzano tutti i passaggi che portarono la città sul Mar Nero ad essere considerata un centro rappresentativo di italianità e europeità.

Proposta di sottotitolazione in italiano del film "Я шагаю по Москве" (1963)

Il tema del mio elaborato finale è la sottotitolazione del film “A passeggio per Mosca” di Georgij Danelija (1963), un noto regista russo. I suoi film più famosi sono “Мимино” (Mimino) e “Осенный марафон” (“Maratona d’autunno”). L’attore protagonista del film è Nikita Michalkov, famoso attore e regista, nonché personaggio controverso della vita culturale russa; il suo film più famoso è “Утомлённые солнцем” (“Sole ingannatore”). I personaggi più anziani furono interpretati da attori famosi quali Rolan Bykov, attore di teatro, e Vladimir Basov, regista e attore straordinariamente versatile. I ruoli principali, invece, furono affidati ad attori meno noti: Aleksej Loktev e Evgenij Steblov, che si dedicarono entrambi al teatro per gran parte della propria vita, e Galina Pol’skich, che divenne una grande attrice di film drammatici. Straordinari sono anche il lavoro dell’operatore cinematografico Vadim Jusov e quello del compositore Andrej Petrov. Il film suscitò diverse impressioni nel pubblico e nella critica e fu accolto positivamente da Chruščёv: presto sarebbe diventato un simbolo del “Disgelo”, un periodo in cui Chruščёv effettuò un’opera di destalinizzazione dell’URSS: il clima era quindi più disteso, sebbene vi fosse un malcontento diffuso a causa dell’economia fallimentare dello Stato. La canzone finale, che contribuì al successo del film, esprime perfettamente quest’atmosfera spensierata, che pervade anche Mosca, la vera protagonista del film. Della capitale vengono inquadrati i luoghi più importanti: tra questi il parco Gorkij, la metropolitana e il GUM. Tradurre i sottotitoli del film non è stato facile. In particolare, ho incontrato difficoltà nel tradurre alcune particelle russe che non hanno un equivalente in italiano e battute in cui erano presenti importanti riferimenti culturali. Il lavoro a cui mi sono dedicata con più impegno è stato la traduzione della canzone finale: desideravo che i sottotitoli italiani fossero in rima e conservassero il significato dei versi originari.
