Pełny tekst źródłaENGLISH ABSTRACT: During the history of Israel the concept of "purity" had developed as a way in which God's people could honour his holiness and draw nearer to him, as a sanctified nation. By the time of Jesus, in Second Temple Judaism, the purity system had become restrictive. This had been influenced by political and social developments, including an increased desire to withdraw from Hellenistic and other factors which were seen as contaminating the integrity of Judaism. There were diverse perceptions regarding the achievement of the purity of Israel, including militaristic confrontation and expulsion of alien occupation forces, stricter adherence to the Law and, in some cases, total withdrawal from general society (such as at Qumran). It was, however, particularly the Pharisaic imposition of the supplementary oral tradition, supposed to clarify the written Law, which imposed hardship on those who, through illiteracy or inferior social status, were unable to meet all the minute provisions which would ensure ritual purity. The expansion of the Law of Moses by the commentary of the rabbis, which over time became the entrenched oral "tradition of the fathers", was originally intended to promote access to God by clarifying obscure points of the Law, in the pursuit of purity. However, this oral tradition had, in fact, become an instrument of alienation and separation of the ordinary people not only from the Pharisees, who considered themselves as the religious elite, but also from God. The common people, that is, a large section of the population, felt rejected and on the outside of both religious and social acceptance. On the material level they also suffered under a heavy tax burden, from both Temple and State, which aggravated their poverty. It was this situation which Jesus confronted in his mission to change the ideological climate and to reveal the Kingdom of God as being accessible to all who accepted the true Fatherhood of God, in penitence and humility. He denounced the hypocrisy which professed piety but which ignored the plight of those who were suffering. Hark 7 : 1-23 symbolizes the difference between the teaching and practice of Jesus and that of the Pharisees, and provides metaphorically a pattern of Christian engagement which is relevant in the South African situation today. The Christian challenge is to remove those barriers, both ideological and economic, which impede spiritual and material well-being within society. By active engagement, rather than by retreating to the purely ritualistic and individualistic practice of religion, the realization of the Kingdom of Heaven, as inaugurated by Jesus, will be advanced.
AFRIKAANSE OPSOMMING: Gedurende die geskiedenis van Israel het die konsep van reinheid ontwikkel as 'n wyse waarin die die volk van God Sy heiligheid kan eer en tot Hom kan nader, as 'n geheiligde volk. Teen die tyd van Jesus, tydens Tweede Tempel Judaïsme, het die reinheid sisteem beperkend geword. Dit is beïnvloed deur politieke en sosiale ontwikkelinge, insluitende 'n toenemende drang om te onttrek van Hellenistiese en ander faktore, wat beskou is as 'n besoedeling van die integriteit van Judaïsme. Daar was diverse persepsies aangaande die uitvoering van die reinheid van Israel, insluitende militaristiese konfrontasie en die uitwerping van vreemde besettingsmagte, strenger onderhouding van die Wet en in sekere gevalle, totale onttreking van die algemene samelewing (soos by Qumran). Tog was dit in besonder die Fariseërs se oplegging van bykomende mondelinge tradisie, veronderstelom die geskrewe Wet te verhelder, wat ontbering veroorsaak het vir die wat as gevolg van ongeletterdheid of minderwaardige sosiale status nie in staat was om aan elke haarfyn bepaling, wat rituele reinheid sou verseker, te voldoen nie. Die uitbreiding van die wet van Moses deur die kommentaar van die rabbies, wat met verloop van tyd die ingegrawe mondelinge "tradisie van die vaders" geword het, was oorsproklik bedoel om toegang tot God te verseker, deur die verheldering van onduidelike aspekte van die wet, in die nastreef van reinheid. Hierdie mondelinge tradisie het egter 'n instrument van vervreemding geword en skeiding gebring tussen gewone mense en die Fariseers, sowel as die wat hulleself beskou het as die religieuse elite. Dit het egter ook skeiding gebring tussen mense en God. Die gewone mense, dit is die meerderheid van die bevolking, het verwerp gevoel en aan die buitekring van beide religieuse en sosiale aanvaarding. Op materiële vlak het hulle ook gelyonder die juk van swaar belasting, van beide die Tempel en die Staat, wat hulle toestand van armoede vererger het. Dit was hierdie situasie wat Jesus gekonfronteer het in sy strewe om die ideologiese klimaat te verander en om die Koninkryk van God te openbaar as toeganklik vir almal wat die ware Vaderskap van God aanvaar, in berou en in nederigheid. Hy het die skynheiligheid verwerp wat aanspraak maak op vroomheid, maar die toestand van die lydendes ignoreer. Markus 7:1-23 simboliseer die verskil tussen die onderrig en die praktyk van Jesus en dié van die Fariseërs en voorsien metafories 'n patroon van Christelike verbintenis, wat relevant is binne die eietydse Suid-Afrikaanse konteks. Die uitdaging aan die Christendom is om die skeidslyne te verwyder, beide ideologies en ekonomies, wat geestelike en materieële welsyn binne die gemeenskap belemmer. Deur aktiewe betrokkenheid, eerder as om bloot te onttrek tot die suiwer ritualistiese en individualistiese beoefening van religie, sal die realisering van die Koninkryk van die Hemel soos ingehuldig deur Jesus, bevorder word.

Pełny tekst źródłaLes fonctions purs dans un programme sont ceux qui démontre un comportement sans fonctionnalité ou effet secondaire. Ceci s'avère une propriété utile pour une fonction ou du code dans le contexte d'optimisation et de compréhension du programme. Cependant, récolter de l'information de pureté n'est pas une tâche facile, et les techniques existantes pour les analyses de pureté ne fournissent que des résultats statiques basés sur une analyses de la compilation du programme. Nous avons exécuter une analyse détaillée de la pureté dynamique des fonctions dans des applications Java en utilisant une approche basés sur un Java Virtual Machine (JVM). Nous avons évalué multiples définitions de pureté, forte et faible, et considéré les formats de pureté spécifiques à l'exécution, tout en considérant les contraintes qui nous sont imposées par un application "consommateur" d'information de pureté et de mémorisation. Nous démontrons que malgré la consistance de la pureté dynamique des fonctions parmi certains applications, l'examen du nombre d'invocation pure et le pourcentage de chaîne d'instruction "bytecode" trouvé dans les fonctions purs nous dévoile l'existante de grande variation. Nous montrons aussi que malgré l'affaiblissement de la définition de la pureté expose considérablement la pureté dynamique, les pré-requis des consommateurs peuvent actuellement limiter l'utilité de cet information. Une bonne compréhension de ce qu'est une fonction "pure" et dans quel sens, est une important contribution à comprendre quand, où, et quelles optimisations ou propriétés une application peut dévoilée.

At the turn of the 21st century, an ideological movement defined by many as the modesty movement helped push sexual abstinence as a controversial yet significant public issue in the United States. Concerned with a "hyper-sexualized" culture, modesty advocates urged young women to make a pledge to remain pure until marriage. Following the the growth of the movement, feminist scholars have been critical of the movement and the potentially detrimental consequences of purity pledges on young women's identity, sexuality, and sexual agency. This study takes a step back from this critical view of purity pledges and listens to young women's lived experience of making a purity pledge and living a life of purity. Specifically, this study asks how purity pledgers understand and enact purity and how they perceive their sexuality and sexual agency. To answer these questions, qualitative interviews were conducted with nine young women who at some point in their life made a purity pledge. A thematic analysis revealed three major themes: 1) living a pure life is situated within multifaceted perspectives on purity, 2) living a life of purity consists of negotiating multiple "selves," and 3) living a life of purity grants and reinforces a sense of agency. A composite description illustrates that religious messages, parents, peers, and sex education classes continue to influence their understanding of purity and sexuality. This project concludes with a discussion of theoretical implications surrounding the idea of a "crystallized self" and practical implications of this study on an organizational, familial, and personal level.

Pełny tekst źródłaRecent developments of electrical segmentation of HPGe detectors, coupled with digital electronics have led to promising applications such as γ-ray tracking, γ-ray imaging or low-background measurements which will benefit from a fine knowledge of the detector response. The IPHC has developed a new scanning table which uses a collimated γ-ray beam to investigate the detector response as a function of the location of the γ-ray interaction. It is designed to use the Pulse Shape Comparison Scan technique, which has been simulated in order to prove its efficiency. An AGATA detector has been thoroughly scanned. 2D classical scans brought out, for example, local charge collection modification effects such as charge sharing, due to the segmentation. For the first time, a 3D, complete pulse-shape database has been established. It will especially allow to improve the overall AGATA array performances

Pełny tekst źródładiffusion controlled (as compared to chemical control for gold in the absence of lead). However, high concentrations of lead were found to be detrimental to the leaching process. It is believed that the role of lead is to modify the surface by cementation, hence reducing the effect of the passive film. Silver was also found to be effective at reducing passivation, and the role of silver believed to be similar to that of lead. It was found that unlike lead, high concentrations of silver are not detrimental to the dissolution of gold in cyanide solutions.Solid phase purity was also found to be important in the leaching of gold, and it was found that the leaching of a gold sample which contains 1 % silver is diffusion controlled. This finding is important from an industrial viewpoint, as most native gold contains some silver. Consequently, attempts were made to rationalise the leaching of gold/silver with current plant practice. Discussion on the effect of cyanide and oxygen concentrations, temperature and lead addition is presented.
Dungan, James Alexander. "Investigating the Functional Distinction Between Harm and Purity Norms". Thesis, Boston College, 2017. http://hdl.handle.net/2345/bc-ir:107598.
Pełny tekst źródłaMany debates in moral psychology have revolved around the function of harm norms (e.g., against causing pain to others) and purity norms (e.g., against sexual deviance or consuming taboo foods). Two key pieces of this debate are 1) whether purity norms constitute a separate moral domain than harm norms, each with distinct evolved functions, and 2) if so, whether the function of purity norms is to guard people from disgusting behavior that may signal the threat of disease-causing pathogens. Paper 1 addresses the first point by examining how increasing attention to a violator’s mental states (e.g., whether they acted intentionally or accidentally) changes the way people process harm and purity violations. Using behavioral and neuroimaging techniques, it supports a growing literature demonstrating that judgments of purity violations are influenced less by information about the violator’s intent than judgments of harm violations and suggests distinct functions for harm and purity norms. Paper 2 addresses both points by examining how the relational-context of a violation (e.g., whether an action is directed at oneself or another person) impacts judgments of harm and purity violations. Three studies demonstrate that unlike moral judgments of harm violations, moral judgments of purity violations are more tied to the negative impact a violator has on themselves as opposed to others. Moreover, when a participant was the target of another person’s impure actions, their moral judgments of the action were predicted more by perceptions of harm than purity, suggesting that purity norms do not necessarily track concerns about pathogen exposure. Finally, given the evidence in Papers 1 and 2, Paper 3 tests a novel functional distinction between harm and purity norms whereby harm norms regulate the negative impact people have on each other while purity norms function to define group boundaries by setting expectations about how people conduct themselves. Together, these papers challenge current accounts of the evolutionary origins of harm and purity norms and suggest important new avenues for fully characterizing the function of distinct moral norms

This dissertation illuminates how expert labor makes a complex natural substance into a uniform global commodity. Drawing on both published sources and extensive archival research in the continental United States, in Scotland, and in Puerto Rico, it provides new insight into the workings of the empires of commodities that define modem capitalism. Chapter 1 shows that the notion that sugar has a single valuable molecular essence sucrose- has been used to explain its history as a commodity. Yet this essentialism is not a natural fact but a product of the political economy of the late nineteenth century itself. From the seventeenth century on, sugar production had relied on the experienced multisensory techniques of enslaved craftsmen. But after 1860, newly sophisticated factories began to appear throughout the Caribbean, producing sugar of unprecedented consistency and quality. Chapter 2 explores how the work of chemists was essential to managing labor within these new factories, whose owners attempted to eliminate the need for artisan work. Yet the more successfully chemists extracted sucrose from sugarcane, the more mechanical and obvious they made that extraction appear, and the more they effaced their own necessity. These efforts to use scientific expertise to de-skill sugar production were made possible, Chapter 3 shows, by the persistence of craft and cooperative production in Glasgow, where those factories' machines were built. Sugar engineering firms cultivated relationships with distant plantations, ensuring that draftsmen and engineers could design, maintain, and repair machines that would last many decades. It therefore shows how the devices that facilitated sugar's commodification have human histories themselves. Finally, Chapter 4 reveals how the valuation of sugar became a central political issue in the postbellum United States. The Federal government feared its means of enforcing sugar tariffs was being undermined by fraud on the part of Customs officers and by new forms of sugar itself. But supposedly objective chemical techniques were even harder for the state to supervise. In showing how powerful refiners shaped scientific practices to their own advantage, this chapter provides a new framework for historians' analyses of science, commodities, and corruption in the nineteenth century.

Pełny tekst źródłaOptics represents an elegant and reliable solution to generate high spectral purity microwave signals, especially the approach using the optoelectronic oscillator (OEO). The spectral purity of these sources is very important for space and military applications and also for time and frequency domain metrology. During this thesis, we have fabricated and studied many types of resonator based OEO in order to optimize the system phase noise. We have especially investigated an original approach using a passive fiber ring resonator (FRR). This resonator type can feature optical quality factors higher than 109 when only few meters of optical fibers are used (L ~ 10 m) and it can be easily integrated in a planar setup. Moreover, we have performed an important work on 3D WGM resonators based oscillators. In the FRR based OEO, spectacular progresses have been achieved thanks to a good understanding of the system intrinsic noise phenomena. Actually, we have found that the most important noise parameters were the laser FM and AM noise conversion into RF phase noise by means of different nonlinearities in the system (like the photodiode nonlinearity), but also by the generation of nonlinear optical effects inside the resonator. By controlling these effects, we have been able to reduce the OEO phase noise level and to reach a -128 dBc/Hz noise level at 10 kHz offset frequency from a 10. 2 GHz carrier. This has been achieved using an OEO based on a 100m-long passive FRR, which has been optimized and immunized against different nonlinear optical effects
Gianotti, Elia. "High purity hydrogen generation via partial dehydrogenation of fuels". Thesis, Montpellier 2, 2014. http://www.theses.fr/2014MON20078/document.
Pełny tekst źródłaThis thesis work have been developed in the general context of the development of more electrified and environmentally friendly means of transport, in order to significantly reduce greenhouse gases emissions. More specifically, the objective of this thesis project was to study the feasibility of the concept of on-board hydrogen generation by catalytic partial dehydrogenation (PDh) of fuel. The hydrogen produced serves to power a fuel cell system that replaces vehicles auxiliary power units. At the same time the fuel, that is only partially dehydrogenated, maintains its properties and can be re-injected into the fuel pool.This thesis is divided into two main parts. The first part describes the research on the PDh of kerosene to produce hydrogen on-board an aircraft. The choice of the catalyst is crucial: it should allow to produce high purity hydrogen without compromising the original properties of kerosene. Advanced materials, composed by metals impregnated on different supports, have been developed, characterized and evaluated as a catalysts in the reaction of PDh. The influence of catalyst composition on the activity, selectivity and stability as well as the deactivation mechanisms were studied. One of the optimized catalytic materials, composed of a 1% Pt - Sn 1% (w/w) active phase supported on a γ-alumina with controlled porosity, allowed a hydrogen production of 3500 NL•h-1•kgcat-1, with a purity of 97.6% vol. and a lifetime of 79 h, which corresponds to 3.5 kW of electric power supplied by fuel cells.The second part of the manuscript describes a study on diesel and gasoline and asses the feasibility of hydrogen generation by PDh of fuels different from kerosene. The results obtained with the previously mentioned catalyst are encouraging and show the possibility of applying this concept to other fields of transportation beside the aviation. The most significant results obtained with gasoline and diesel surrogates are respectively a hydrogen productivity value of 3500 et 1800 NL•h-1•kgcat-1 with lifetimes of 29 and 376 h and a purity that exceeds 99% vol. in both cases

Pełny tekst źródłaAn innovative oscillator for solid-state laser technology is developed for Single-Longitudinal-Mode (SLM) operation, enabling narrow bandwidth, low pulse-to-pulse time jitter, laser emission at 1064 nm. The system realized is fully characterized in terms of power, energy, spatial, temporal and spectral performance. The technology developed is defined Self Injection Seeding Ring Oscillator (SISRO), which enables to generate close to transform limited pulses with remarkable reliability and unparalleled simplicity. Both Coherent Doppler LIDARs (CDL) and High Spectral Resolution LIDARs (HSRL) can benefit from this technology, in terms of cost-efficiency, reliability and complexity. An additional significant advantage introduced by the SISRO laser architecture is modularity. This property allows to tailor the technology to the desired application and LIDAR system. Both CDL and HSRL are thus presented, after the fundamental principles governing standard LIDAR techniques have been introduced. CDL is intended to measure the motion of winds whereas HSRL is employed for discrimination between molecules and particulate matter. In both applications, the systems share the need of a laser source able to generate narrow bandwidth pulses in order to discriminate spectral broadening induced into the backscattered radiation. The SISRO technique exploits a unidirectional ring architecture to suppress Spatial Hole Burning (SHB), which is the main antagonist to SLM operation. Unidirectional propagation and thus SLM operation is achieved by means of self-seeding. The SISRO technique emerges as an appealing candidate for Master Oscillator Power Amplifier (MOPA) architectures, because of the good spatial, spectral, temporal properties and the significant pulse energies involved (uJ order), which can be easily scaled depending on the application. It is also discussed nonlinear techniques to extend the wavelength operation. Indeed, conventional laser systems struggle to access specific wavelengths, which are required for both physical reasons and health considerations, such as laser safety. Nonlinear devices enable to shift conventional high energies laser to exotic wavelengths. In this elaborate is presented nonlinear parametric oscillators for wavelength extension from 1 um to the Short-Wavelength InfraRed (SWIR) region (1.8-2.5 um). Each part is independently addressed in different chapters of this work. First, it is introduced the LIDAR technology and optical requirements. Then, the optical theory necessary to develop the SISRO, such as Passive Q-Switching and SLM operation, is described. Subsequently, the novel SISRO laser and the several iterations of the architecture based on Neodymium active materials are presented. The key parameters governing the SISRO performance and especially stability are also investigated in details, while the reader is also made aware of the typical trends associated with comparable technologies. Experimental results and theoretical predictions are thoroughly discussed, in order to understand the advantages offered by the SISRO technique and to devise suggestions to overcome its major limitations. The nonlinear theory for wavelength extension is thereafter introduced. Both Optical Parametric Ocillators (OPO) and Backward-Wave Optical Parametric Oscillators (BWOPO) systems are described, in combination with an Optical Parametric Amplifier (OPA) aimed at the extension of the spectral coverage offered by traditional bulk devices. In these regards, particular attention is dedicated to the spectral performance, showing the trade-off between these two oscillators technologies.
