description: For autonomous driving, the accurate perception of the vehicle’s environment is a key requirement. For this purpose, radar sensors provide reliable images, even in poor lighting or weather conditions. In this paper, the imaging performance of snapshots obtained from a high-resolution 4D radar with 1728 channels is compared to occupancy grid maps (OGMs) and synthetic aperture radar (SAR) images captured with a low-end sensor. Therefore, measurements are performed on a parking lot, representing a typical automotive scenario. Additionally, OGMs obtained from both the low-end sensor and the 4D imaging radar are compared. SAR images show the best imaging performance, overcoming shadowing effects and the degradation due to angular sidelobes. However, the snapshots from the 4D imaging radar also contain the relevant targets and provide velocity and height information at the same time.
description: Für das autonome Fahren ist die genaue Wahrnehmung der Umgebung des Fahrzeugs eine wichtige Voraussetzung. Zu diesem Zweck liefern Radarsensoren zuverlässige Abbildungen, auch bei schlechten Licht- oder Wetterverhältnissen. In diesem Beitrag wird die Leistungsfähigkeit von Einzelbildern, die mit einem hochauflösenden 4D-Radar mit 1728 Kanälen aufgenommen wurden, mit Occupancy Grid Maps (OGMs) und SAR-Bildern (Synthetic Aperture Radar) verglichen, die mit einem einfachen Sensor aufgenommen wurden. Dazu werden Messungen auf einem Parkplatz durchgeführt, der ein typisches Automobilszenario darstellt. Außerdem werden OGMs verglichen, die sowohl mit dem Low-End-Sensor als auch mit dem 4D-Imaging-Radar aufgenommen wurden. Die SAR-Bilder zeigen die beste Bildqualität, da sie weder Abschattungseffekte noch die Beeinträchtigung durch Nebenkeulen enthalten. Die Einzelbilder des bildgebenden 4D-Radars enthalten jedoch auch die relevanten Ziele und liefern gleichzeitig Geschwindigkeits- und Höheninformationen.

Aspect-Oriented User Requirements Notation
Creators: name: Mussbacher, Gunter
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2011
Subjects: subject: Computer Science.

description: Technologies based on aspects and applied at the early stages of software development allow requirements engineers to better encapsulate crosscutting concerns in requirements models. The Aspect-oriented User Requirements Notation (AoURN) extends the User Requirements Notation (URN) with aspects and thus unifies goal-oriented, scenario-based, and aspect-oriented concepts in one graphical framework. As URN is a standard of the International Telecommunication Union, AoURN is the first standards-based and graphical approach that integrates the three aforementioned techniques. Minimal changes to URN ensure that requirements engineers can continue working with goal and scenario models expressed in a familiar notation. With AoURN, concerns in goal and scenario models, regardless of whether these concerns crosscut or not, can be managed across model types. Typical concerns in URN are non-functional requirements, use cases, and stakeholder goals. As AoURN expresses concern composition rules with URN itself, it is possible to describe rules in an exhaustive and highly flexible way that is not restricted by any specific composition language. In addition, AoURN employs a composition technique that is not based solely on language syntax but takes semantics into account, and therefore is more robust to refactoring of an aspect-oriented model Since composition based on semantics requires precisely defined languages, the semantics of URN is clarified and the concrete syntax enhanced to capture identified semantic variations of the language. A qualitative comparison of aspect-oriented techniques for scenario-based and goal-oriented requirements engineering is presented. An evaluation carried out based on metrics adapted from literature and a task-based evaluation suggest that AoURN models are more scalable than URN models and exhibit better modularity, reusability, and maintainability. A proof-of-concept implementation of AoURN in the jUCMNav tool is also discussed. While AoURN's ability to encapsulate concerns across model types further bridges the gap between goals and scenarios, Early Aspects research benefits from a standardized way of modeling concerns with AoURN.

description: Studies indicate that teachers, and in particular science teachers in the senior high school grades, do not integrate laptop computers into their instruction to the extent anticipated by researchers. This technology has not spread easily to other teachers even with improved access to hardware and software, increased support, and a paradigm shift from teacher-centred to student-centred education. Although a number of studies have focused on the issues and problems related to the integration of laptops in classroom instruction, these studies, largely quantitative in nature, have tended to bypass the role teachers play in integrating laptop computers into their instruction. This thesis documents and describes the role of Ontario high school science teachers in the integration of laptop computers in the classroom. Ten teachers who have successfully integrated laptop computers into their biology courses participated in this descriptive study. Their perceptions of implementing laptops into their biology courses, key factors about the implementation process, and how the implementation was accomplished are examined. The study also identifies the conditions which they feel would allow this innovation to be implemented by other teachers. Key findings of the study indicate that teachers must initiate, implement and sustain an emergent and still evolving innovation; teacher perceptions change and continue to change with increased experience using laptops in the science classroom; changes in teaching approaches are significant as a result of the introduction of laptop technology; and, the teachers considered the acquisition and use of new teaching materials to be an important aspect of integrating laptop computers into instruction. Ongoing challenges for appropriate professional development, sharing of knowledge, skills and teaching materials are identified. The study provides a body of practical knowledge for biology teachers who are considering the integration of laptops into their instruction. The results are of interest to science teachers, those whose decisions affect the meaningful integration of technology in science education, those researching the teaching of science in secondary schools and those who prepare science graduates to teach at this level. Key Words: innovation, laptop, computer, biology, science, secondary, implementation, perceptions, instruction, professional development, qualitative, descriptive.

description: Sialic acid has been sought as an excellent candidate for $\sp2$H NMR studies because of its ubiquitous presence at the penultimate non-reducing ends of membrane glycoproteins and glycolipids and because it has been associated with a number of biological and immunological phenomena. Regio- and stereoselectively deuteriated sialyl glycerolipids 1a, 1b and 1c were required for these studies and were synthesized.(DIAGRAM, TABLE OR GRAPHIC OMITTED...PLEASE SEE MAI) The first step of the synthetic route developed, involved the synthesis of unlabeled and labeled glycerolipids. The regio- and stereoselective deuterium incorporations in sialic acid and subsequent transformation of the deuteriated sialic acids into their respective glycosyl donors followed. The glycosylation of the glycerolipids with the appropriate glycosyl donors completed the synthesis of the model sialylglycerolipids and prompted further investigations of glycosidation methods for the synthesis of sialyl glycosides. A phase transfer catalysis procedure, particularly useful in the synthesis of thiosialosyl donors, was developed and the applicability of the procedure to produce a wide range of S- and O-sialosyl derivatives was explored. An extensive study of thioglycosylation reactions using a series of thiosialosyl donors, the glycerolipid and various thiophilic promoters resulted in the introduction of the concept of active and latent thiosialosyl donors which concluded the synthetic aspect of this research.

description: Global focal companies are increasingly required and expected to monitor the sustainability risks and activities in their supply chains, which has resulted in increasing supplier sustainability audit activity and growth in the number of sustainability initiatives/associations. While common, shared audit standards were originally conceived to reduce audit fatigue; with overlapping and converging supply chains there could be a need for cross-recognition or standardisation of supplier audit standards. This research aims to provide empirically grounded insight into sustainability audit activity, audit processes and standards for suppliers and the extent to which they overlap. Audit standards employed by eight multi-brand, voluntary sustainability initiatives/associations, focusing on supply chain sustainability (SMETA, PSCI, ICTI, FWF, ASI, JAC, amforiBSCI and RBA) were inductively analysed. This research compares the audit processes and standards, detecting common audit categories, analysing points of overlap and difference. We find empirical evidence of significant growth in supplier sustainability audit activity. We also find overlap among the standards in terms of audit process and steps, as well as at the level of audit focus categories. Deeper analysis reveals large differences at the granular level in terms of questions asked to assess specific topics. We conclude that there is potential for standardisation and cross-recognition but that significant barriers to agreement at the level of audit questions and how topics are evaluated remain. This research provides a first empirical overview of this important tool and its application in various industries for sustainable supply chain management.

description: We report work progress on the growth of Si quantum dots in different matrices for future photovoltaic applications. The work reported here seeks to engineer a wide-bandgap silicon-based thin-film material by using quantum confinement in silicon quantum dots and to utilize this in complete thin-film silicon-based tandem cell, without the constraints of lattice matching, but which nonetheless gives an enhanced efficiency through the increased spectral collection efficiency. Coherent-sized quantum dots, dispersed in a matrix of silicon carbide, nitride, or oxide, were fabricated by precipitation of Si-rich material deposited by reactive sputtering or PECVD. Bandgap opening of Si QDs in nitride is more blue-shifted than that of Si QD in oxide, while clear evidence of quantum confinement in Si quantum dots in carbide was hard to obtain, probably due to many surface and defect states. The PL decay shows that the lifetimes vary from 10 to 70 microseconds for diameter of 3.4nm dot with increasing detection wavelength.

description: Background: Chronic back disorders (CBD) are prevalent, costly, and among the most common reasons for seeking primary care; however, little is known regarding the comparative use of family physician, chiropractic, and physiotherapy services among people with CBD in Canada. Elucidating these differences may identify potential gaps in access to care and inform the development of strategies to improve access. The research objectives were to investigate patterns of health care use and to profile factors associated with self-reported use of family physicians, chiropractors, and physiotherapists among adult Canadians with CBD. Methods: The combined 2009 and 2010 Canadian Community Health Surveys conducted by Statistics Canada were used to investigate self-reported health care use among adults with CBD. This complex survey employs population weights and bootstrapping to be representative of the Canadian population. Following descriptive analyses, we used multiple logistic regression to profile self-reported health care use while statistically controlling for possible confounding effects. Results: The majority of adult respondents with CBD sought care only with a family physician (53.8%), with 20.9% and 16.2% seeking care with combined family physician/chiropractor or family physician/physiotherapist, respectively. Few respondents sought care only with a chiropractor (2.5%) or physiotherapist (1.0%). After adjustment, differential patterns of utilization (p < 0.05) were evident between provider groups with respect to age, gender, socioeconomic status, rural/urban residence, functional limitations, and presence of co-morbidities. Conclusions: This research highlights potential inequities in access to physiotherapists and chiropractors in relation to family physicians among adult Canadians with CBD, particularly among lower socioeconomic status and rural/remote populations.

description: Cette thèse s'intéresse aux stratégies et techniques produites par notre société, une société du risque à l'ère néo-libérale, afin d'actualiser le gouvernement d'individus. À cet effet, nous nous sommes attardés à un terrain d'étude particulier, soit le documentaire télévise, en tant que forme de média, sur le phénomène des gangs de rue. Nous avons analysé ce matériau afin de comprendre comment, au travers du discours qui le produit et qu'il produit en retour, il participe au gouvernement de soi et plus précisement, à la subjectivation des individus, voire de l'audience. Cette démarche s'est actualisée par l'identification des énoncés du discours dans lequel s'actualisent les documentaires, énoncés qui régissent les modalités relatives aux individus voulant devenir sujets de celui-ci. Ainsi, nous avons pu repérer les caractéristiques propres aux sujets produits par les documentaires télévisés en matière du phénomène des gangs de rue à la lumière du contexte d'une nouvelle rationalité politique dans laquelle ils émergent.
Gender and Global Biodiversity From 'Women and Plants' to International Law

Subjects: subject: Geography.

description: This thesis examines the channels of communication that facilitate the transfer of gendered ecological knowledge from 'women and plants' to international law. It investigates the source of women's ecological knowledge in Latin American rural villages and identifies characteristics of this knowledge by exploring ethnographic case studies. Rural Latin American women's knowledge of their ecosystems and the plants they use is essential not only to household survival, but also to the conservation of biodiversity. Given the concern over the rapid decline in global biodiversity and the importance of the Convention on Biological Diversity as an international binding (to the parties that have ratified it) agreement that enjoys widespread support, this study examines the role of the bodies of the CBD in considering and documenting gendered ecological knowledge. It suggests that the role of civil society in the capture and transfer of women's ecological knowledge is key. Despite policy that includes a comprehensive Gender Plan of Action, a profound understanding of the need for a gender focus when considering ecological knowledge is still lacking within the actions of the bodies and parties of the CBD. NGOs and TANs are well positioned to bring evidence from their work in rural villages in Latin America (and across the world) that will help bring the issues of gendered ecological knowledge closer to the policy table. It is suggested here that giving rural women in Latin America and the world over a voice in the international arena is essential, not only for biodiversity conservation but also for poverty eradication.
Assessing and addressing research-practice gaps in practitioners' provision of decision support for terminally-ill cancer patients considering the place of their end-of-life care: Design and evaluation of a multi-faceted educational intervention

Subjects: subject: Health Sciences, Nursing.

description: Background. A paradox exists between preferred place of end-of-life cars (home/hospice) and actual place of care (hospital). Patients often need help with decision making yet practitioners generally lack skills in providing quality decision support. Purpose. To evaluate an intervention designed to address barriers to providing decision support for place of end-of-life care. Objectives were to: (1) describe nurses' perceptions of factors that affect their provision of decision support; and (2) design and evaluate the efficacy of an educational intervention for strengthening the quality of practitioners' decision support. Design and methods. (1) Systematic review: Synthesis of primary research studies investigating factors influencing place-of-care. (2) Needs assessment: Semi-structured interviews with 22 nurses. (3) Randomized trial: Comparison of intervention and control groups on the quality of decision support provided to simulated patients considering place of care before and after training. Setting of the Needs Assessment and Randomized Trial. Ontario palliative and oncology practice settings. Results (1) Systematic Review: Of 735 papers identified, 39 papers (33 studies) met inclusion criteria. Factors related to the illness, the individual and the care and social environment influence place of end-of-life care for cancer patients. Commonly identified factors were patient preference, social supports and health care resources. Stated preference, care-giver presence and contact patterns with health care services influence place of end-of-life cancer care. (2) Needs assessment: Nurses held favourable attitudes towards providing decision support for place-of-care at end-of-life. Nurses considered decision support an important part of patient-centred care yet identified a lack of skills, confidence and tools as barriers. (3) Randomized control trial: The before-after changes in the quality of decision support were greater (p<0.0001) in the intervention group (mean change 3.75, 95%Cl: 2.46, 5.03) compared to the control group (mean change -0.667, 95% Cl: -1.57, 0.24). Conclusions. Numerous determinants influence terminal cancer patients' decision making about place of care. Nurses believe they have a role in providing decision support, but lack skills, confidence and tools. These barriers can be addressed with an educational program and a patient decision aid. Broad implementation of the intervention may improve end-of-life care planning. Full implementation of the intervention requires examination of broad system perspectives.

Potential eutrophication of the Rideau River by an urban drainage waterway.

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1977
Subjects: subject: Engineering, Civil.

description: Urban drainage within the City of Ottawa, Ontario, is thought to be a significant contributor of nutrients to the already eutrophic Rideau River. Both chemical characterization and algal bioassay were used to study the nutrient effects of Saw Mill Creek, a major urban drainage waterway to the Rideau River. Saw Mill Creek was sampled during peak storm flow, when both high concentrations of nutrients and high flow conditions prevailed. Peak flows averaged 9 percent of the flow in the Rideau during the study period. Although nutrient concentrations were shown to be greater during storm flows, peak flow concentrations for total phosphorus and nitrogen averaged only 0.190 mg-P/l and 2.5 mg-N/l. These concentrations of nutrients did not significantly stimulate algal growth at the 5 percent addition level. However, at the 10 and 20 percent addition level, bioassays produced on the average 0.96 and 1.96 mg/l of algal standing biomass, respectively. These values were significantly different (P<0.05) from the average biomass of 0.50 mg/l produced by the Rideau samples. Alum treatment of Saw Mill Creek, simulated by the jar test, was generally unable to reduce algal growth when compared at any of the addition levels. The treated 5 percent addition produced virtually the same average algal biomass as the untreated, and thus it was concluded that treatment would have no effect on algal growth at low flows of Saw Mill Creek. It was recommended that a non-structural solution for the reduction of storm flows in Saw Mill Creek be sought, so that the associated decrease of nutrient concentrations would reduce the algal growth potential.

Subjects: subject: Chemistry, Organic.

description: This project was launched with the aim of developing dendrimer catalysts for oxidation and reduction reactions. Poly(amidoamine) (PAMAM) and poly(propyleneimine) (PPI) dendrimers were of interest because of their well-established synthesis. Chapter 1 describes the fundamentals of dendrimers and provides a brief insight of their application in catalysis. In particular, examples of dendritic catalysts that have been previously employed as oxidation and reduction catalysts are presented. Chapter 2 presents the synthesis and characterization of silica-supported PAMAM dendrimers, their phosphomethylation with Ph2 PCH2OH, and their complexation to palladium complexes. Chapter 3 reports the application of the silica-supported PAMAM-Pd complexes to the oxidation of alkenes to methyl ketones under Wacker-type conditions as well as the use of tBuOOH as the oxidant in these reactions. Chapter 4 discusses the use of the above-mentioned complexes to catalyze the selective hydrogenation of dienes to monoolefins in the presence of H2 under mild reaction conditions. Chapter 5 presents our efforts in modifying PPI dendrimers with the salen moiety to give ligands that are coordinated to the metals Ti and V. Attempts at using the former complexes to promote the epoxidation of alkenes and the latter complexes to catalyze the epoxidation of olefinic alcohols are discussed.

description: Background: DNA methylation is influenced by both environmental and genetic factors and is increasingly thought to affect variation in complex traits and diseases. Yet, the extent of ancestry-related differences in DNA methylation, their genetic determinants, and their respective causal impact on immune gene regulation remain elusive. Results: We report extensive population differences in DNA methylation between 156 individuals of African and European descent, detected in primary monocytes that are used as a model of a major innate immunity cell type. Most of these differences (~ 70%) are driven by DNA sequence variants nearby CpG sites, which account for ~ 60% of the variance in DNA methylation. We also identify several master regulators of DNA methylation variation in trans, including a regulatory hub nearby the transcription factor-encoding CTCF gene, which contributes markedly to ancestry-related differences in DNA methylation. Furthermore, we establish that variation in DNA methylation is associated with varying gene expression levels following mostly, but not exclusively, a canonical model of negative associations, particularly in enhancer regions. Specifically, we find that DNA methylation highly correlates with transcriptional activity of 811 and 230 genes, at the basal state and upon immune stimulation, respectively. Finally, using a Bayesian approach, we estimate causal mediation effects of DNA methylation on gene expression in ~ 20% of the studied cases, indicating that DNA methylation can play an active role in immune gene regulation. Conclusion: Using a system-level approach, our study reveals substantial ancestry-related differences in DNA methylation and provides evidence for their causal impact on immune gene regulation.

description: The apparent molar volumes, Ov, of a series of tetra-n-alkylammonium bromides have been measured down to high dilutions by means of a modified Stokes and Hepler dilution dilatometer and at higher concentrations with a differential buoyancy balance. Despite conflicting indications in earlier literature, the present measurements have shown that the limiting law slope for the apparent molar volume is approached at sufficiently high dilutions. Measurements of the apparent molar volume and the apparent molar adiabatic compressibility have also been carried out on a series of substituted pyridinium and piperidinium salts. The effects associated with indirect and direct blocking at the N+ centre were observed with these two series of salts and allowed comparisons to be made with the results of measurements carried out on a series of alkylammonium salts where direct blocking of the charge centre arises. The partial molar volume and adiabatic compressibility of aqueous solutions of neutral pyridine and piperidine bases were also investigated. The apparent molar volume of these solutes showed pronounced maxima and minima when evaluated as a function of concentration. Some measurements of Ov in D2O solutions for the same solutes also showed a similar type of concentration dependence.

description: The Simple Temporal Network with Uncertainty (STNU) model focuses on the representation and evaluation of temporal constraints on time-point variables (timepoints), of which some (i.e. contingent timepoints) cannot be assigned (i.e. executed by the system), but only be observed. Moreover, a temporal constraint is expressed as an admissible range of delays between two timepoints. Regarding the STNU model, it is interesting to determine whether it is possible to execute all the timepoints under the control of the system, while still satisfying all given constraints, no matter when the contingent timepoints happen within the given time ranges (controllability check). Existing approaches assume that the original contingent time range cannot be modified during execution. In real world, however, the allowed time range may change within certain boundaries, but cannot be completely shrunk. To represent such possibility more properly, we propose Simple Temporal Network with Partially Shrinkable Uncertainty (STNPSU) as an extension of STNU. In particular, STNPSUs allow representing a contingent range in a way that can be shrunk during run time as long as shrinking does not go beyond a given threshold. We further show that STNPSUs allow representing STNUs as a special case, while maintaining the same efficiency for both controllability checks and execution.

description: The C14-labelled synthetic substrates, carbobensoxy-L-glutamyl-L-tyrosine and its ethyl ester were synthesised by the condensation of carbobenzoxy-L-glutamic anhydride and L-tyrosine ethyl ester. C14glutamic acid and C14 tyrosine were used in these syntheses giving substrate molecules labelled in the glutamic acid moiety or in the tyrosine moiety. The various radioactive substrates were incubated at pH 4.0 with pepsin. After a given period of time, the pepsin was isolated from the incubation mixture and found to be radioactive only when substrates containing C 14-tyrosine were involved. This radioactive protein was found to liberate C14-tyrosine ethyl ester upon incubation in acid solution. These facts were taken as evidence that the radioactive protein isolated is an intermediary complex pepsin-tyrosine ethyl ester formed during the hydrolysis of the peptide derivative by the proteolytic enzyme. A mechanism is proposed to explain the formation of such a complex. After partial acid hydrolysis of this radioactive complex, paper chromatography and paper electrophoresis were used to isolate a radioactive peptide. The amino acid composition of this peptide was found to be the following: alanine, aspartic acid, serine, glutamic acid, threonine, glycine, arginine, valine, tyrosine and leucine. We claim that this peptide represents part of the active center of pepsin.

As universities are under constant pressure to improve the productivity of academic staff within universities, we examine the role of social interaction in fostering entrepreneurial activities. A web-based survey is implemented, facilitated by empirical analysis using correlation and multiple regression to probe the relationship between these constructs. Whilst in can be concluded that the constructs are all multidimensional, varying relationships were identified when statistically examining the interrelations. Overall, there is a significant relationship between social interaction and productivity. lntrapreneurship also portrays such significance, albeit varying between dimensions of autonomy, innovativeness, risk taking, proactiveness and competitive aggressiveness.

description: Ramularia leaf spot is a major economic disease of barley caused by the dothidiomycete fungus Ramularia collo-cygni. The fungus has a complex life cycle which includes extensive late season spore release events and a seed-borne phase. Predicting disease epidemics during the growing season remains a difficult challenge. To better understand the interaction between spore movement and disease epidemics, spore samplers were set up in Germany (two sites over 4 years), Poland (seven sites over 2 years) and the UK (two sites over 9 years), where the disease has been observed. Spore concentrations were determined using a real time PCR assay, and meteorological data were obtained from co-located automatic stations. Spore release events were seen to peak in June on mainland Europe and July in the UK. The pattern of spore release was broadly similar across countries with earlier peaks in mainland Europe. A relationship was observed in the UK between July spore levels and disease in following winter barley crops. Rainfall and temperature were proposed as significant drivers of spore release in these months. The major environmental parameter associated with spore release across the two UK sites was crop surface wetness, although some site-specific interactions were noted for rainfall and wind movement. Regression analysis of spore patterns and disease epidemics indicates a relationship between spore levels 75â€Ì105 days pre harvest and final disease levels in UK winter barley crops. This relationship was not observed in spring barley. The implications on risk forecasts are discussed.

description: This thesis deals with the design and construction of a communication system for a digital equipment corporation PDP-8 digital computer. The thesis first shows the general operation of the computer and the specifications of the required system and then proceeds to study various possible designs which could meet the specifications. The designs are compared and the one considered best chosen. This chosen design is further developed and its implementation using integrated circuits is shown in detail. The design of the system is discussed as a function of the various tasks that the subsystems must accomplish.
Sustaining the democratic medium: philanthropy and community radio in Australia

description: The community radio sector in Australia has been experiencing rapid growth as a result of the increase in the number of licensed radio stations. However, Australian government funding has not proportionally increased, thus threatening the financial viability of many community radio stations. A key issue to be addressed is the need to find ways to enhance community radio's sources of funding without imperilling its status as a not-for-profit sector. Philanthropy is therefore an option that community radio stations could cultivate and develop. Philanthropy and community radio have a lot in common, as they are both connected in their mission. Philanthropy involves active community capital building and community radio is dedicated to offering media services to the community. Common objectives can lay a solid foundation for a pro-active financial relationship. This paper looks into the nature of philanthropy and explores the opportunity of it acting as a potential source of income for community media in Australia.

description: COPHES/DEMOCOPHES has its origins in the European Environment and Health Action Plan of 2004 to "develop a coherent approach on human biomonitoring (HBM) in EuropeŁ. Within this twin-project it was targeted to collect specimens from 120 mother-child-pairs in each of the 17 participating European countries. These specimens were investigated for six biomarkers (mercury in hair; creatinine, cotinine, cadmium, phthalate metabolites and bisphenol A in urine). The results for mercury in hair are described in a separate paper. Each participating member state was requested to contract laboratories, for capacity building reasons ideally within its borders, carrying out the chemical analyses. To ensure comparability of analytical data a Quality Assurance Unit (QAU) was established which provided the participating laboratories with standard operating procedures (SOP) and with control material. This material was specially prepared from native, non-spiked, pooled urine samples and was tested for homogeneity and stability. Four external quality assessment exercises were carried out. Highly esteemed laboratories from all over the world served as reference laboratories. Web conferences after each external quality assessment exercise functioned as a new and effective tool to improve analytical performance, to build capacity and to educate less experienced laboratories. Of the 38 laboratories participating in the quality assurance exercises 14 laboratories qualified for cadmium, 14 for creatinine, 9 for cotinine, 7 for phthalate metabolites and 5 for bisphenol A in urine. In the last of the four external quality assessment exercises the laboratories that qualified for DEMOCOPHES performed the determinations in urine with relative standard deviations (low/high concentration) of 18.0/2.1% for cotinine, 14.8/5.1% for cadmium, 4.7/3.4% for creatinine. Relative standard deviations for the newly emerging biomarkers were higher, with values between 13.5 and 20.5% for bisphenol A and between 18.9 and 45.3% for the phthalate metabolites. Plausibility control of the HBM results of all participating countries disclosed analytical shortcomings in the determination of Cd when using certain ICP/MS methods. Results were corrected by reanalyses. The COPHES/DEMOCOPHES project for the first time succeeded in performing a harmonized pan-European HBM project. All data raised have to be regarded as utmost reliable according to the highest international state of the art, since highly renowned laboratories functioned as reference laboratories. The procedure described here, that has shown its success, can be used as a blueprint for future transnational, multicentre HBM projects.

description: This thesis was conducted to establish the background for a plan to document the elimination of indigenous wild polio in Canada. Three independent studies were conducted to address the adequacy of polio detection in Canada: (a) a critical review of the existing surveillance system for poliomyelitis in Canada; (b) a retrospective chart review of acute flaccid paralysis (AFP) cases presenting in the Ottawa-Carleton Regional Municipality during a 5-year period (1986-1991); and (c) a cross-sectional survey in Ottawa-Carleton of physicians' awareness about the presentation of poliomyelitis, and their investigative practices for AFP in general. The overall conclusions from the chart review and the physician survey are that among physicians in the study region (a) the index of suspicion for paralytic poliomyelitis is very low, and (b) overall knowledge about the presentation of polio, appropriate diagnostic tests, and requirements for notification are poor, or else not adequately applied. On the basis of the above findings, the conclusion is that Canada does not currently meet the PAHO requirements for certification of a polio-free status. In addition, there is insufficient evidence from the data obtained for the supposition of wild polio elimination in Canada. Recommendations are presented for improving polio surveillance and for establishing protocols for investigation and control of polio. (Abstract shortened by UMI.)
