An integrated indoor-outdoor assessment of the sources and impacts of air pollution in rural India : linking low-cost measurement, modelling and impact assessment
Creators: name: Chakraborty, Mrinmoy
Publisher: name: University of British Columbia
Year: 2025

description: Mitigating household air pollution in low- and middle-income countries (LMICs) is critical for sustainable development and saving lives. This thesis explores strategies to reduce black carbon (BC) exposure from burning solid biomass fuels (SBFs) in rural Indian households. In Chapters 1 and 2, an extensive literature survey explores the challenges and opportunities in BC monitoring. Emphasis is placed on how advanced techniques can enhance actionable research, particularly in developing engineering solutions and policies for economically disadvantaged populations. Key research questions and gaps are highlighted to steer future studies. Chapter 3 focuses on the assessment of a BC monitoring device. A portable battery-operated microaethalometer was evaluated for BC mass concentration monitoring with a high degree of precision compared to a reference aethalometer (slope range 0.73-1.01, R2 = 0.9). The chapter also explores established aethalometer correction protocols and suggests methods for estimating source contributions. Chapter 4 employs an integrated data collection approach using surveys and BC data from rural northern India. With 81% of households using SBF, intra-day BC fluctuations occurred both indoors (4.2 to 37.6 µgm−3) and outdoors (5.7 to 33.3 µgm−3). Rapid BC changes are mainly due to atmospheric ventilation post-morning cooking. Surveys and BC data helped form hypotheses on fuel-use related to atmospheric conditions, helping to inform interventions: e.g., hypothesized optimal SBF cooking times. Chapter 5 presents the nested mass balance-box (NMB2) model, parameterized with field data and scholarly sources. This model employs the Monte Carlo method to simulate hourly concentrations of indoor-outdoor BC concentrations under various household interventions, such as transitioning fuels and enhancing ventilation, to assess the efficacy of ways to mitigate BC exposure. Transitioning fully to LPG can decrease BC levels during cooking by 99% in poorly ventilated homes. An interesting finding was noted for homes with complete fuel transition to LPG and high ventilation: infiltration of outdoor air led to a slight 9% increase in BC concentration. Chapter 6 summarizes key findings and lessons from the thesis, offering evidence-based decision guidance for reducing BC exposure through the study’s holistic approach of field campaigns, advanced instruments, and modeling.

description: This thesis documents an exploratory study of the degree Philosophiae Doctor (Ph.D.). It was prompted by the international existence of several contentious aspects of the degree (appropriateness, attrition, discrimination, employment, program emphasis, research competency evaluation, time to complete, unconventional programs). Because of the absence of any relevant theory, a model (Ph.D. acquisition model) was utilized as the conceptual framework for the investigation. This model incorporates the three fundamental components of the degree (lengthy study, original research, thesis preparation), which were determined from the historical and regulatory literature. The research question was, " (w) hat effect, either positive or negative, do experts think altering the fundamental components of the degree Philosophiae Doctor, will most likely have on the resultant degree?" Data to answer this question was derived using the prognostic Delphi technique involving a panel of 67 (15 females, 52 males) English-speaking individuals. These professionals have extensive experience with the Ph.D. degree and they come from Australia, Canada, Great Britain, and the United States. In the Round 1 questionnaire the panelists identified Ph.D. degree related problems that were validated against the prescriptive literature (1960-1988). Round 2 generated predictive responses about the outcome of 18 hypothetical actions which address the most frequently raised problems in Round 1. A reiterative Round 3 resulted in acceptably stable prognoses for the majority of the responses. The implications of these prognoses, as they relate to the traditional and four non-traditional Ph.D. degrees and to university administrators are discussed.

description: The digital economy, heralded as a new economic paradigm, has emerged as a formidable driver of national economic growth. The "2019 Digital Economy Report" from the United Nations Conference on Trade and Development underscores that the digital economy encompasses not only digital industries like information technology but also industrial digitalization, the infusion of digital technology into traditional sectors, leading to their transformation into pillars of the digital economy. The evolution of the digital economy, the advancement of digital technology, and the rapid adoption of digital tools have all ascended to a strategic national priority, playing a pivotal role in socioeconomic development and enhancing living standards. In the era of economic globalization, international trade agreements, such as China's free trade areas with other nations, have fortified regional commercial cooperation and trade interactions. However, within the global value chain, intermediate goods traverse borders multiple times, engendering issues of "double counting" in traditional trade metrics based on total commodity values. Consequently, these metrics fail to accurately gauge the value added by individual countries. Enter the trade benefit index, grounded in value-added trade statistics, offering a more precise reflection of a nation's real gains from international trade and serving as a vital indicator of trade prowess.
The problem of Socrates' goodness: An application of Gregory Vlastos' account of Socratic irony.
Creators: name: Pierlot, John F. J.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1998
Subjects: subject: Philosophy.

description: Socrates is supposed to be a good man, but he consistently disclaims the very knowledge of goodness which he thinks one has to have in order to be good. This is the problem of Socrates' goodness. But Socrates' ignorance is ironic, not in the sense that when he says he lacks moral knowledge he means he really has it, but rather in the sense that he holds a set of moral intuitions that he considers true because they have survived the test of the elenchus. Thus his ignorance is characteristic of what Gregory Vlastos has called "complex irony," an irony consisting of the articulation of two senses of knowing. Socrates disclaims godly wisdom but at the same time he reclaims wisdom in another, more contingent sense, consistent with his conviction that what he does know has withstood the rigours of his unique method of critical discussion. Vlastos' notion of complex irony is a valuable clue for understanding how Socrates might be good. Socrates is good to the extent that he lives in a manner that is consistent with some reasonable intuitions about how a good person lives his/her life. At the same time, however, Socrates' moral knowledge is self-admittedly deficient. This means that not only is his ignorance characteristic of complex irony, so too, by the same token, is his goodness. Socrates is justified in believing that he is good in the sense that he conforms to as much as he does know about the human good, but he is also not-good in that he knows he still cannot fully satisfy the requirements of the doctrine that knowledge is necessary and sufficient for goodness.
AI: A cure for Baumol's disease?
Creators: name: Doyle, Gillian

Publisher: name: CREATe
Year: 2024

description: The production of outputs in cultural industries, including film and television etc, is said to suffer from Baumol’s disease in that, because of its emphasis on creative labour elements which cannot readily be mechanised, replicated by computers nor streamlined, it is prone to above-average inflation. However, recent developments in generative AI, with its capacity to assist in generating text, images and sound, have established unprecedented opportunities to automate and support aspects of creative work across media industries. What does this imply for Baumol’s cost disease? This paper examines recent developments in AI, and analyses to what extent, by potentially reducing costs and raising productivity in inflation-prone media content creation activities, these technologies challenge conventional theory and effectively counteract Baumol’s disease.
More web slave than web master: Internet hate speech, corporate ISPs and hard and soft law in the United States
Creators: name: Smith, Ian
Publisher: name: Swinburne
Year: 2024

description: Efforts to tighten European speech laws increased dramatically in 2001 with the Council of Europe's adoption of the Convention on Cybercrime. The Internet, however, is unrestricted by national borders and it is feared that relatively freer countries, namely the United States, could become so-called 'haven nations' for hate speech. But largely left out of the academic literature is any appreciation of the 'social soft law' regime in that country which routinely circumvents First Amendment speech rights. Although the US's Bill of Rights unquestionably entrenches free speech, which after the Yahoo! Case has clearly been held to apply to the Internet, due to the corporatisation of ISPs Internet speech in the US is actually highly controlled. The internet speech 'regulators' in question are certain 'human rights' NGOs, and their role has yet to be seriously analysed by legal academics. This article surveys the legal infrastructure supporting the social soft law regime in the US and provides an analysis of the NGO 'regulatory' activity that is allowed to take place. A particular focus of the article is the policing of anti-Semitic speech, and how it may be treated and, at times, abused by the NGO industry without sufficient scrutiny.

description: In this work, binary phase masks are designed and implemented for use with a photoconductive terahertz (THz) emitter in order to shape the frequency response of the emitted THz waveforms. Theoretical and experimental results are applied to study the system. The theoretical results are presented in the form of both numerical simulations (to characterize and uniquely identify the underlying time-delayed photogeneration and resulting charge-carrier dynamics) and a simplified model (to conceptualize the system). The theoretical and experimental results are found to agree. It is ultimately shown that the phase delay through the binary phase mask can be used to preferentially allocate power into bands within the THz spectrum. Such results can lay the groundwork for future studies needing precise control of power within the THz spectrum.

Garnet reaction mechanisms in polymetamorphic rocks from central Maine
Creators: name: Burreson, Matthew James
Publisher: name: University of Iowa
Year: 2001

description: The polymetamorphic terrane in west central Maine is an ideal place to investigate reaction mechanisms involving garnet because the garnet has undergone multiple growth and dissolution phases. This study examines the origin of the complex zoning patterns and relates them to the P-T history of the area.
description: The rocks have gone at least three separate periods of metamorphism (M1, M2 and M3). M1 is a regional greenschist event between 418 and 405 Ma.
description: M2 is a staurolite + garnet + biotite +/- andalusite bearing assemblage with an age of approximately 405 Ma and is responsible for the initial garnet growth. Cooling after M2 produced the high grossular ring observed in most garnets. The pressure increase between M2 and M3 was responsible for growing the high Ca ring.
description: M3 heating is responsible for dissolving garnet due to staurolite forming reactions, growing garnet because of staurolite dissolving at higher temperatures or dissolving garnet due to the growth of sillimanite. It is comprised of three events. M3a resulted from the intrusion of Phillips pluton at approximately 403 Ma. M3b resulted from the older pulse of the Mooselookmeguntic complex approximately 390 Ma and M3c resulted from the younger pulse of the Mooselookmeguntic complex approximately 370 Ma.
description: Gibbs modeling indicates M2 metamorphism resulted from increasing P and T from 480oC at 1.4 kbars to maximum temperatures between 554oC and 560oC at 3.0 kbars, not isobaric heating at 3.0 kbars. Modeling of the M3 zoning patterns and textures suggests M3 metamorphism was caused by isobaric heating to maximum temperatures of 561°C to 575°C at 3.5 kbars.

description: L'intégration des TIC à l'école, de par les nouvelles possibilités offertes et de par la variété des activités réalisables, interpelle la manière d'enseigner et d'apprendre. Cette recherche examine, par la méthode d'étude de cas, les représentations des enseignants d'une école élémentaire suite à l'intégration des TIC. Le but de cette recherche est de mieux comprendre la façon dont les enseignants vivent les changements qui y sont rattachés ainsi que les facteurs qui favorisent et ceux qui freinent une telle innovation. L'intégration des TIC étant un domaine encore peu connu et la nature de notre question nécessitant une description du phénomène vécu, nous avons procédé par entretiens semi dirigés auprès des enseignants d'une école élémentaire. La recherche s'inscrit donc dans une démarche interprétative. L'analyse des résultats a fait ressortir des changements vécus regroupés sous quatre thèmes principaux : les retombées pédagogiques, l'évolution des rôles, les transformations sociales et l'organisation du travail au sein de l'école. De plus, cette étude montre les potentialités des TIC en milieu minoritaire, notamment celles de contribuer à renforcer le noyau culturel francophone et à briser le sentiment d'isolement en encourageant le développement d'une communauté d'apprentissage professionnelle. Les discours mettent aussi en évidence des facteurs personnels favorables qui sont principalement les attitudes des enseignants et les avantages percus pour l'élève. Quant aux facteurs organisationnels favorables, les propos soulignent la formation, l'appui, le leadership de la direction de l'école, une structure collaborative, les pressions et les modèles cotoyés. Enfin, les facteurs défavorables à l'intégration des TIC selon les représentations des enseignants de notre étude, semblent être surtout les conséquences néfastes tant chez les élèves que chez les enseignants ainsi que les attitudes négatives. Quant aux facteurs organisationnels défavorables ils seraient liés au manque de temps, aux difficultés techniques, au manque d'équipement et de soutien. L'étude a aussi fait ressortir des profils particuliers des enseignants en tenant compte de la personnalité des individus, de leurs préoccupations face à l'innovation, de l'utilisation qu'ils en font ainsi que des représentations qu'ils ont de leurs compétences avec les TIC. Les représentations des changements vécus et des facteurs favorables et défavorables varient compte tenu de ces profils.

description: This dissertation aims to discuss the design of international interventions, or institutions and practices (Reus-Smith 2013), and their implications on their benefiting populations. Institutions are habitually created using a standard rational design approach and a feminist lens is often neglected. Vulnerable populations, particularly women, are often the beneficiaries of these interventions, yet they are not included in the design process, which led to the overarching question for this dissertation “Why don’t institutions serve and protect their intended beneficiaries' needs and interests?”. This dissertation brings to light the tension between these two literatures and the implications it has on designing institutions. It highlights the importance of including the experiences of populations, specifically women, in the creation of these interventions to create a working structure for everyone involved. This three-article dissertation focuses on international treaties, peace agreements, and government policies to see where feminist lenses should be, and why they are helpful. The data for this project consists of an original quantitative dataset of CEDAW articles and two other quantitative datasets created from the World Values Survey (Haerpfer et al. 2020), EM-DAT (Guha-Sapir et al. 2021), and PA-X Agreement Dataset (Bell et al. 2020). When examining government responses to natural disasters I find that when there are a high number of disasters and when a larger percentage of the population is affected by disasters, women’s political trust decreases significantly, especially institutional trust. Regarding peace agreements, I find that Truth and Reconciliation along with specific types of Amnesty create a more durable positive peace within post-conflict states. Finally, when examining the treaty CEDAW I find that naming and shaming from reputable organizations focused on feminist ideals and women’s rights do not affect when states remove their reservations from the treaty, demonstrating the lack of a feminist approach to CEDAW design and international structure contributing to human rights. Returning to the research question, institutions do not serve and protect their intended beneficiaries' needs and interests, because they lack a feminist approach to institutional design. These findings indicate the need for interventions to be created using a feminist approach, to serve the intended audiences. This research could inform the creation of new institutions, or the changing of old ones, to better enhance the international system for all.

Cooper pair ring model

Year: 2020
Subjects: subject: Superconductivity (cond-mat.supr-con)

description: The superconducting state starts to collapse when the externally applied magnetic field exceeds the Meissner-Ochsenfeld critical field, Bc,MO, which in type-I superconductors is the thermodynamic critical field, while in type-II superconductors this field is the lower critical field. Here we show that both critical fields can be described by the universal equation of $B$$_{c,MO}$=$μ$$_0$$n$$μ$$_B$$ln(1+2$$^{0.5}$$κ$), where $μ$$_0$ is the magnetic permeability of free space, $n$ is the Cooper pairs density, and $μ$$_B$ is the Bohr magneton, and $κ$ is the Ginzburg-Landau parameter. As a result, the Meissner-Ochsenfeld field can be defined as the field at which each Cooper pair exhibits the diamagnetic moment of one Bohr magneton with a multiplicative pre-factor of $ln(1+2$$^{0.5}$$κ$). In the two-dimensional case this implies that the Cooper pair center of mass is spatially confined within a ring with inner radius $ξ$ and outer radius of $ξ$+2$^{0.5}$$λ$, where $ξ$ is the coherence length and $λ$ is the London penetration depth. This means that the superconducting transition is associated not only with the charge carrier pairing, but that the pairs exhibit a new topological state with genus 1.

description: Background Biological pathways that significantly contribute to sporadic Alzheimer’s disease are largely unknown and cannot be observed directly. Cognitive symptoms appear only decades after the molecular disease onset, further complicating analyses. As a consequence, molecular research is often restricted to late-stage post-mortem studies of brain tissue. However, the disease process is expected to trigger numerous cellular signaling pathways and modulate the local and systemic environment, and resulting changes in secreted signaling molecules carry information about otherwise inaccessible pathological processes. Results To access this information we probed relative levels of close to 600 secreted signaling proteins from patients’ blood samples using antibody microarrays and mapped disease-specific molecular networks. Using these networks as seeds we then employed independent genome and transcriptome data sets to corroborate potential pathogenic pathways. Conclusions We identified Growth-Differentiation Factor (GDF) signaling as a novel Alzheimer’s disease-relevant pathway supported by in vivo and in vitro follow-up experiments, demonstrating the existence of a highly informative link between cellular pathology and changes in circulatory signaling proteins.

description: The construction industry, a ubiquitous sector worldwide, plays a pivotal role in job creation and addressing unemployment. However, it also ranks among the most perilous occupations, marked by a history of accidents leading to worker injuries and fatalities. This study investigates the imperative of ensuring a safe and healthy working environment for construction workers, encompassing their physical, physiological, and psychological well-being, collectively referred to as Work Health and Safety (WHS). Governments worldwide have enacted legislation to safeguard construction worker safety, yet work-related accidents continue to plague the industry. In 2014 alone, over 73,000 injuries were documented in the American construction sector, underscoring the severity of the issue.

This article examines the multifaceted consequences of workplace accidents, including economic ramifications, legal implications, ethical considerations, and the impact on workforce motivation. By delving into these dimensions, it sheds light on the urgent need for enhanced safety measures and a comprehensive WHS framework within the construction business.

description: This paper concerns the positive part $U^+_q$ of the quantum group $U_q({\widehat{\mathfrak{sl}}}_2)$. The algebra $U^+_q$ has a presentation involving two generators that satisfy the cubic $q$-Serre relations. We recently introduced an algebra $\mathcal U^+_q$ called the alternating central extension of $U^+_q$. We presented $\mathcal U^+_q$ by generators and relations. The presentation is attractive, but the multitude of generators and relations makes the presentation unwieldy. In this paper we obtain a presentation of $\mathcal U^+_q$ that involves a small subset of the original set of generators and a very manageable set of relations. We call this presentation the compact presentation of $\mathcal U^+_q$.

Subjects: Paper industry, deforestation, environmental impact, sustainable alternatives, biodiversity

description: For over two millennia, paper has been a pivotal medium of human communication and knowledge preservation. Its evolution from ancient materials like bamboo, silk, and papyrus to modern wood-based production signifies an integral part of our cultural history. However, the contemporary paper industry's overwhelming reliance on tree resources is unsustainable and detrimental to the environment. Approximately 40% of the world's commercially harvested timber is consumed by the paper production sector, resulting in the annual destruction of over 30 million acres of forests.

The environmental impact of the paper life cycle is concerning, commencing with the felling of trees and culminating in carbon-emitting incineration. Water consumption in paper production further compounds the issue, with an A4 sheet demanding 10 liters of water. Notably, the United States, housing only 5% of the global population, consumes 30% of the world's paper, with the forest and paper products industry generating a substantial $200 billion in annual revenue.

The consequences of deforestation, driven by the paper industry and others, are perilous for our environment and biodiversity. This paper examines the detrimental ecological effects of paper production, emphasizing the urgency of adopting sustainable alternatives and conservation measures
Approaches to 3,3-disubstituted azetidinones.

description: Chapter 1 contains a very brief overview of 3,3-disubstituted azetidinones. Also included in this chapter are the approaches to 'hybrid' azetidinones, i.e. those which contain the structural features of more than one class of azetidinones. Finally the target molecules for the present studies are listed. Chapter 2 contains details of use of various 2,3-dihydroxybutyric acid derivatives in enantioselective syntheses of 3-alkoxyazetidinones with an additional substituent at position 3. In chapter 3 similar studies on threonine derivatives for the syntheses of 3-amino-3-hydroxyethylazetidinones are described. These studies were only partially successful. In chapter 4 a systematic approach towards the syntheses of 3-alkoxyazetidinones is described. The steps involved were the formation of the C-3 carbanion from the parent azetidinones, reaction with acetaldehyde, oxidation of the resulting 3-alkoxy-3-hydroxyethylazetidinones and finally the reduction of the acetyl compound in a non-chelation controlled manner. It has been possible to synthesize protected 3-amino-3-hydroxyethylazetidinones by a similar series of reaction and the results are presented in chapter 5. Chapter 6 has details of syntheses of 3-hydroxy, 3-hydroxy-3-hydroxyethyl, 3-hydroxy-3-allyl and 3-$\sp\prime$epoxy$\sp\prime$azetidinones. Chapter 7 contains results of a detailed study on the impact of various variables on the non-chelation controlled reduction of 3-acylazetidinones (which have an additional substituent at 3-position). Chapter 8 is about the use of N, N-dimethylchloromethylenimnium chloride for the purpose of activating carboxylic acids for their final conversion to azetidinones. An attempt was made to determine the nature of the white solid obtained on reaction of DMF with oxalyl chloride, and the product of reaction between this white solid and a carboxylic acid.

description: Objectives The present study aimed to evaluate the frequency of warning signs in younger patients with stroke with a special regard to the ‘FAST’ scheme, a public stroke recognition instrument (face, arm, speech, timely). Setting Primary stroke care in participating centres of a multinational European prospective cross-sectional study (Stroke in Young Fabry Patients; sifap1). Forty-seven centres from 15 European countries participate in sifap1. Participants 5023 acute patients with stroke (aged 18–55 years) patients (96.5% Caucasians) were enrolled in the study between April 2007 and January 2010. Primary and secondary outcome measures sifap1 was originally designed to investigate the relation of juvenile stroke and Fabry disease. A secondary aim of sifap1 was to investigate stroke patterns in this specific group of patients. The present investigation is a secondary analysis addressing stroke presenting symptoms with a special regard to signs included in the FAST scheme. Results 4535 patients with transient ischaemic attack (TIA; n=1071), ischaemic stroke (n=3396) or other (n=68) were considered in the presented analysis. FAST symptoms could be traced in 76.5% of all cases. 35% of those with at least one FAST symptom had all three symptoms. At least one FAST symptom could be recognised in 69.1% of 18–24 years-old patients, in 74% of those aged 25–34 years, in 75.4% of those aged 35–44 years, and 77.8% in 45–55 years-old patients. With increasing stroke severity signs included in the FAST scheme were more prevalent (National Institute of Health Stroke Scale, NIHSS<5: 69%, NIHSS 6–15: 98.9%, NIHSS>15: 100%). Clustering clinical signs according to FAST lower percentages of strokes in the posterior circulation (65.2%) and in patients with TIA (62.3%) were identified. Conclusions FAST may be applied as a useful and rapid tool to identify stroke symptoms in young individuals aged 18–55 years. Especially in patients eligible for thrombolysis FAST might address the majority of individuals.
Roman mime and the public purse
Creators: name: Porter, Jennifer

description: The popularity of Roman mime endured for centuries and the genre occupied protean performance spaces, including circuses, theatres and amphitheatres, where its inclusion in public spectacles came – at least in part – at the expense of the public purse. Mime was a lewd performance genre with a reputation for ribaldry; it needled at the strict Roman social hierarchy. This thesis examines the paradoxical relationship between the Roman state and performers of this provocative genre, and is guided by the question: why would the Roman state sponsor the inclusion of mimes in its public entertainment? Chapter One identifies and examines twelve fragmentary mime scripts, revealing evidence for the routine use of props, costume, and musical instrumentation. This analysis implies that mime performances required a significant degree of preparation, often involving specialized props, planned percussive accompaniment, and visual character cues, undermining the notion of mime as a primarily improvised genre. This chapter positions Roman mime as a polished commodity for purchase by the state or private individuals. Chapter Two focuses on the economic relationship between mime troupes and their patrons and uses documentary records of their remuneration to examine the ways in which they were paid. This chapter finds that whilst mimes could be remunerated in both cash and in kind, there appeared to be a preference for the Roman state to pay in cash and for private individuals to pay in kind. Chapter Three employs Bakhtin’s theory of “folk carnival” to examine why Roman officials might fund performances of a genre that frequently mocked and parodied Roman institutions. This chapter also considers the didactic function of mime through analysis of Choricius of Gaza’s sixth-century Apologia Mimorum. Through examination of the papyrological, literary and material evidence for mime as it appeared on the stage, this thesis augments scholarly understanding of the practicalities of such performances. Having reframed mime as a commodity for purchase by the Roman state, and having assembled the papyrological evidence for performers’ remuneration, this thesis argues that the temporary inversion of Roman social values offered by mime routines served to reinforce these strict values outside of the performance space.

description: My work is foundationally rooted in collage. A collage is intuition meeting discovery. I really crave the discovery part, and how that enriches and confirms my own unique sense of self and identity. Before I was an artist, I was a stage actor and a songwriter. I developed fiction and poetry writing practice. I work almost daily, playing, with paper, glue, clay, glaze, antiques, fibers and textiles, fashion implements, sometimes sounds and music, words, and other bits and pieces, all within self-made limitations, based on intentional pursuit of the relationship between self-revelation and material relationship investigations, making more and more discoveries in consideration of color and composition, the usage of text and language, and how the work is bound to my own story.
Undersampled differential phase shift on-off keying for optical camera communications with phase error detection

description: This paper introduces the design and implementation of an optical camera communication (OCC) system. Phase uncertainty and phase slipping caused by camera sampling are the two major challenges for OCC. In this paper, we propose a novel modulation scheme to overcome these problems. The undersampled differential phase shift on-off keying is capable of encoding binary data bits without exhibiting any flicker to human eyes. The phase difference between two consecutive samples conveys one-bit information which can be decoded by a low frame rate camera receiver. Error detection techniques are also introduced to enhance the reliability of the system. Furthermore, we present the hardware and software design of the proposed system. This low-cost communication system has been implemented with a Xilinx FPGA and a Logitech commercial camera. Experimental results demonstrate that a bit-error rate of 10-⁵ can be achieved with 7.15 microwatts received signal power over a link distance of 15 centimeters.
La modèle occidental et ses traductions dans une société postcommuniste: Le cas de la Roumanie

Subjects: subject: Language, General.

description: Cette étude vise à montrer comment le transfert et la propagation des représentations par l'intermédiaire de la traduction, comme système et comme pratique sociale, instaurent des modèles mentaux qui permettent d'expliquer ou d'assigner des significations spécifiques à des événements récents. Considérée comme un champ des prises de position et de circulation conflictuelle des idées, la traduction permet de configurer un état du discours social et de montrer comment une société en mutation et subissant une crise du sens s'objective dans des textes et des pratiques collectives. Le cas envisagé est celui d'un espace postcommuniste, en l'occurrence celui de la Roumanie depuis 1989. La traduction apparaît comme une conséquence de l'ouverture du pays après la chute du communisme. Elle permet d'observer le cheminement d'une culture qui se modifie ou se modernise sous l'impact de la diffusion de représentations nouvelles, créées dans l'espace de communication Ouest-Est, ou suite à l'actualisation de représentations passées. Elle dynamise l'imaginaire de la société roumaine, prédisposant cette culture à engendrer, à maintenir ou à rejeter certaines croyances, mythes ou idées, tout comme à réfléchir sur des problèmes contemporains. À partir d'un corpus de textes, originaux et traduits, appartenant à la littérature, aux sciences humaines et sociales et regroupant aussi des articles de presse, l'étude montre comment la traduction participe à l'éveil de la conscience publique. Au-dela de cette incidence sociale immédiate, elle permet d'eclairer d'autres types de transferts intra- ou interculturels parce qu'elle propose d'autres modèles, d'autres représentations dans le nouvel espace social.
Insecticidal and synergistic properties of Piper nigrum seed extracts investigated using acute toxicity assays and gene expression profiling of Drosophila melanogaster

description: The overall objective of this study was to investigate the insecticidal and synergistic properties of an ethylacetate extract of Piper nigrum L. (Piperaceae) seeds used alone and in conjunction with pyrethrin, a botanical insecticide extracted from the flowers of Chrysanthemum cinerariaefolium Benth. & Hook. (Asteraceae). It was concluded that P. nigrum extract is a highly promising candidate for a novel botanical synergist for pyrethrin and could potentially be used as a replacement for piperonyl butoxide in certain pyrethrum formulations. The upregulation of mRNA transcripts encoding cytochrome P450 detoxification enzymes by a P. nigrum extract may indicate possible target proteins to enhance the toxicity of insecticides and synergists. The seven common genes differentially expressed in two or three of the sublethal treatments with pyrethrin, P. nigrum extract or pyrethrin plus P. nigrum extract merit further study of their functions relating to detoxification processes and defense responses. Future work should include a detailed, tissue-specific characterization of the genes of interest identified in this study and an investigation of the activity of the P. nigrum extract against the CYP enzymes associated with the Cyp genes that were differentially expressed in response to a P. nigrum extract.

description: Using Chandra data taken in 2008 June, we detected pulsations at 2.594 39(4) s in the soft gamma-ray repeater SGR 1627âˆ’41. This is the second measurement of the source spin period and allows us to derive for the first time a long-term spin-down rate of (1.9Â±0.4)Ã—10âˆ’11 s sâˆ’1. From this value, we infer for SGR 1627âˆ’41 a characteristic age of ~2.2 kyr, a spin-down luminosity of ~4 Ã— 1034 erg sâˆ’1 (one of the highest among sources of the same class), and a surface dipole magnetic field strength of ~2 Ã— 1014 G. These properties confirm the magnetar nature of SGR1627âˆ’41; however, they should be considered with caution since they were derived on the basis of a period derivative measurement made using two epochs only, and magnetar spin-down rates are generally highly variable. The pulse profile, double-peaked and with a pulsed fraction of 13 Â± 2 per cent in the 2â-10 keV range, closely resembles that observed by XMMâ-Newton in 2008 September. Having for the first time a timing model for this soft gamma-ray repeater (SGR), we also searched for a pulsed signal in archival radio data collected with the Parkes radio telescope 9 months after the previous X-ray outburst. No evidence for radio pulsations was found, down to a luminosity level ~10â-20 times fainter (for a 10 per cent duty cycle and a distance of 11 kpc) than the peak luminosity shown by the known radio magnetars.
