description: We present an analysis of the relative bias between early- and late-type galaxies in the Two-degree Field Galaxy Redshift Survey (2dFGRS) – as defined by the η parameter of Madgwick et al., which quantifies the spectral type of galaxies in the survey. We calculate counts in cells for flux-limited samples of early- and late-type galaxies, using approximately cubical cells with sides ranging from 7 to 42 h−1 Mpc . We measure the variance of the counts in cells using the method of Efstathiou et al., which we find requires a correction for a finite volume effect equivalent to the integral constraint bias of the autocorrelation function. Using a maximum-likelihood technique we fit lognormal models to the one-point density distribution, and develop methods of dealing with biases in the recovered variances resulting from this technique. We then examine the joint density distribution function, f(δE, δL) , and directly fit deterministic bias models to the joint counts in cells. We measure a linear relative bias of ≈1.3, which does not vary significantly with ℓ. A deterministic linear bias model is, however, a poor approximation to the data, especially on small scales (ℓ≤ 28 h−1 Mpc) where deterministic linear bias is excluded at high significance. A power-law bias model with index b1≈ 0.75 is a significantly better fit to the data on all scales, although linear bias becomes consistent with the data for ℓ≳ 40 h−1 Mpc .

description: Cette these cherche a demontrer qu'il existe en droit canadien, quelques incertitudes juridiques relatives aux transferts de fonds par telecommunications. En l'absence d'un cadre juridique precis sur les droits et obligations des parties intervenant aux transfert de fonds par telecommunications, la determination des concepts de faute et de responsabilite est laissee aux regles de droit commun. Nous examinons les incertitudes reliees a l'erreur, le retard, l'ordre ambigu, la validite des clauses d'exoneration de responsabilite, la determination de l'achevement et la revocabilite. Les regles degagees sont analysees parallelement a la Loi-type proposee par les Nations Unies et au reglement administratif sur le systeme de transfert de paiements de grande valeur que le Canada vient de prendre tres recemment. Malgre ce reglement de portee limitee, des incertitudes subsistent toujours dans le droit canadien sur les transferts de fonds par telecommunications tant interieurs qu'internationaux. Elles portent notamment sur la repartition inegale des risques du systeme ce qui peut compromettre la popularite de ce mode de paiement.

description: Background: Allele-specific transcriptional regulation, including of imprinted genes, is essential for normal mammalian development. While the regulatory regions controlling imprinted genes are associated with DNA methylation (DNAme) and specific histone modifications, the interplay between transcription and these epigenetic marks at allelic resolution is typically not investigated genome-wide due to a lack of bioinformatic packages that can process and integrate multiple epigenomic datasets with allelic resolution. In addition, existing ad-hoc software only consider SNVs for allele-specific read discovery. This limitation omits potentially informative INDELs, which constitute about one fifth of the number of SNVs in mice, and introduces a systematic reference bias in allele-specific analyses. Results: Here, we describe MEA, an INDEL-aware Methylomic and Epigenomic Allele-specific analysis pipeline which enables user-friendly data exploration, visualization and interpretation of allelic imbalance. Applying MEA to mouse embryonic datasets yields robust allele-specific DNAme maps and low reference bias. We validate allele-specific DNAme at known differentially methylated regions and show that automated integration of such methylation data with RNA- and ChIP-seq datasets yields an intuitive, multidimensional view of allelic gene regulation. MEA uncovers numerous novel dynamically methylated loci, highlighting the sensitivity of our pipeline. Furthermore, processing and visualization of epigenomic datasets from human brain reveals the expected allele-specific enrichment of H3K27ac and DNAme at imprinted as well as novel monoallelically expressed genes, highlighting MEA’s utility for integrating human datasets of distinct provenance for genome-wide analysis of allelic phenomena. Conclusions: Our novel pipeline for standardized allele-specific processing and visualization of disparate epigenomic and methylomic datasets enables rapid analysis and navigation with allelic resolution.

description: Starting in 2002, regulations and legislative amendments in Germany focused on the non-smoker protection with several measures to reduce exposure to secondhand tobacco smoke (SHS). The present work aimed to evaluate the relationship between polycyclic aromatic hydrocarbons (PAHs) and SHS exposure and to determine to which extent enforced non-smoking regulations and smoking bans affected the exposure of the non-smoking population in Germany since their implementation in the early 2000s until today. For this purpose, cotinine and selected monohydroxylated PAHs (OH-PAHs) were analyzed by means of (UP)LC-MS/MS in 510 24-h-urine samples of the Environmental Specimen Bank collected over a time span of 24 years from 1995 to 2019. Median urinary cotinine levels were found to steadily and significantly decline by 82% from 1995 to 2019. A significant decrease of urinary 3-hydroxybenzo[a]pyrene (19%), 1-OH-pyrene (39%), 1-naphthol (66%), 1-(17%), 2-(25%), and 3-OH-phenanthrene (22%) was also observed throughout the same time span. The decline in urinary levels of cotinine and several OH-PAHs can most likely be attributed to smoking bans and regulations limiting SHS and PAH exposure. This study therefore emphasizes the relevance of human biomonitoring to investigate the exposure of humans to chemicals of concern, assess the effectiveness of regulatory measures, and help policies to enforce provisions to protect public health. © 2022 The Authors

description: It is well known that the clustering of galaxies depends on galaxy type. Such relative bias complicates the inference of cosmological parameters from galaxy redshift surveys, and is a challenge to theories of galaxy formation and evolution. In this paper we perform a joint counts-in-cells analysis on galaxies in the 2dF Galaxy Redshift Survey, classified by both colour and spectral type, η, as early- or late-type galaxies. We fit three different models of relative bias to the joint probability distribution of the cell counts, assuming Poisson sampling of the galaxy density field. We investigate the non-linearity and stochasticity of the relative bias, with cubic cells of side 10 ≤L≤ 45 Mpc (h= 0.7) . Exact linear bias is ruled out with high significance on all scales. Power-law bias gives a better fit, but likelihood ratios prefer a bivariate lognormal distribution, with a non-zero 'stochasticity', i.e. scatter that may result from physical effects on galaxy formation other than those from the local density field. Using this model, we measure a correlation coefficient in log-density space (rLN) of 0.958 for cells of length L= 10 Mpc , increasing to 0.970 by L= 45 Mpc . This corresponds to a stochasticity σb/b of 0.44 ± 0.02 and 0.27 ± 0.05 , respectively. For smaller cells, the Poisson-sampled lognormal distribution presents an increasingly poor fit to the data, especially with regard to the fraction of completely empty cells. We compare these trends with the predictions of semi-analytic galaxy formation models: these match the data well in terms of the overall level of stochasticity, variation with scale and the fraction of empty cells.

Year: 1999
Subjects: subject: Dance.

description: This thesis focused on the self as dancer explored through narrative and presented through constructed stories. Four dancers were interviewed, two from contemporary dance and two from the classical genre, in order to collect narratives of their career path. The interviews were videotaped and transcribed; the object of the analysis was the interview as text. Only those aspects of the self supported by language were explored in this study. Narrative analysis involved selecting and sequencing events and themes taken from the narratives and writing them into a story for each dancer. The dancers' words were used as much as possible in order to let a sense of how a dancer told about her life and work be present. However, the created stories represent my interpretations of the dancers' texts. Four unique paths to the role of professional dancer are presented.

description: The Two-degree Field Galaxy Redshift Survey (2dFGRS) Percolation-Inferred Galaxy Group (2PIGG) catalogue of ∼29 000 objects is used to study the luminous content of galaxy systems of various sizes. Mock galaxy catalogues constructed from cosmological simulations are used to gauge the accuracy with which intrinsic group properties can be recovered. It is found that a Schechter function is a reasonable fit to the galaxy luminosity functions in groups of different mass in the real data, and that the characteristic luminosity L * is slightly larger for more massive groups. However, the mock data show that the shape of the recovered luminosity function is expected to differ from the true shape, and this must be allowed for when interpreting the data. Luminosity function results are presented in both the bJ and rF wavebands. The variation of the halo mass-to-light ratio, T, with group size is studied in both of these wavebands. A robust trend of increasing T with increasing group luminosity is found in the 2PIGG data. Going from groups with b] luminosities equal to 1010 h-2 L ⊙ to those 100 times more luminous, the typical b J-band mass-to-light ratio increases by a factor of 5, whereas the rF-band mass-to-light ratio grows by a factor of 3.5. These trends agree well with the predictions of the simulations which also predict a minimum in the mass-to-light ratio on a scale roughly corresponding to the Local Group. The data indicate that if such a minimum exists, then it must occur at L ≲ 1010 h-2 L⊙, below the range accurately probed by the 2PIGG catalogue. According to the mock data, the bJ mass-to-light ratios of the largest groups are expected to be approximately 1.1 times the global value. Assuming that this correction applies to the real data, the mean bJ luminosity density of the Universe yields an estimate of Ωm = 0.26 ± 0.03 (statistical error only). Various possible sources of systematic error are considered, with the conclusion that these could affect the estimate of Ωm by a few tens of per cent.

description: The importance of natural gene expression variation for human behavior is undisputed, but its impact on circadian physiology remains mostly unexplored. Using umbilical cord fibroblasts, we have determined by genome-wide association how common genetic variation impacts upon cellular circadian function. Gene set enrichment points to differences in protein catabolism as one major source of clock variation in humans. The two most significant alleles regulated expression of COPS7B, a subunit of the COP9 signalosome. We further show that the signalosome complex is imported into the nucleus in timed fashion to stabilize the essential circadian protein BMAL1, a novel mechanism to oppose its proteasome-mediated degradation. Thus, circadian clock properties depend in part upon a genetically-encoded competition between stabilizing and destabilizing forces, and genetic alterations in these mechanisms provide one explanation for human chronotype.

description: Both excitatory and inhibitory synaptic contacts display activity dependent dynamic changes in their efficacy that are globally termed synaptic plasticity. Although the molecular mechanisms underlying glutamatergic synaptic plasticity have been extensively investigated and described, those responsible for inhibitory synaptic plasticity are only beginning to be unveiled. In this framework, the ultrastructural changes of the inhibitory synapses during plasticity have been poorly investigated. Here we combined confocal fluorescence microscopy (CFM) with high resolution scanning electron microscopy (HRSEM) to characterize the fine structural rearrangements of post- synaptic GABAA Receptors (GABAARs) at the nanometric scale during the induction of inhibitory long-term potentiation (iLTP). Additional electron tomography (ET) experiments on immunolabelled hippocampal neurons allowed the visualization of synaptic contacts and confirmed the reorganization of post- synaptic GABAAR clusters in response to chemical iLTP inducing protocol. Altogether, these approaches revealed that, following the induction of inhibitory synaptic potentiation, GABAAR clusters increase in size and number at the post-synaptic membrane with no other major structural changes of the pre- and post-synaptic elements.

description: It is anticipated that learning and training will become a dominant sector of the global economy within the next decade. The traditional education system is becoming more and more inefficient due to its limitations, such as passive educational environment, limitations of large classes and accessibility. TeleLearning system posses many of the attributes required to solve these problems. TeleLearning system shifts the learners from a passive learning environment to an active learning environment. The learners become the center of the education. Recent advancement in multimedia information processing and the Internet technology allow TeleLearning researchers to simulate real classroom on the Internet, and provide users with access to dynamic multimedia content in a virtual classroom at a time convenient to them. This thesis describes a platform-independent, client/server model for multimedia interactive courseware rendering system. This system helps learners to access course material stored in our multimedia OO database from any access point on the Internet at any time convenient to them.

description: We select a sample of low-redshift (z ∼ 0.1) E+A galaxies from the 2dF Galaxy Redshift Survey (2dFGRS). The spectra of these objects are defined by strong hydrogen Balmer absorption lines (Hδ, Hγ, Hβ) combined with a lack of [O II] 3727-Å emission, together implying a recently truncated burst of star formation. The E+A spectrum is thus a signpost to galaxies in the process of evolution. We quantify the local environments, clustering properties and luminosity function of the E+A galaxies. We find that the environments are consistent with the ensemble of 2dFGRS galaxies: low-redshift E+A systems are located predominantly in the field, existing as isolated objects or in poor groups. However, the luminosity distribution of galaxies selected using three Balmer absorption lines Hδγβ appears more typical of ellipticals. Indeed, morphologically these galaxies are preferentially spheroidal (E/S0) systems. In a small but significant number we find evidence for recent major mergers, such as tidal tails. We infer that major mergers are one important formation mechanism for E+A galaxies, as suggested by previous studies. At low redshift the merger probability is high in the field and low in clusters, thus these recently formed spheroidal systems do not follow the usual morphology-density relation for ellipticals. Regarding the selection of E+A galaxies: we find that basing the Balmer-line criterion solely on Hδ absorption leads to a significant subpopulation of disc systems with detectable Hα emission. In these objects the [O II] emission is presumably either obscured by dust or present with a low signal-to-noise ratio, whilst the (Hγ, Hβ) absorption features are subject to emission-filling.

description: We present the result of a decomposition of the 2dF Galaxy Redshift Survey (2dFGRS) galaxy overdensity field into an orthonormal basis of spherical harmonics and spherical Bessel functions. Galaxies are expected to directly follow the bulk motion of the density field on large scales, so the absolute amplitude of the observed large-scale redshift-space distortions caused by this motion is expected to be independent of galaxy properties. By splitting the overdensity field into radial and angular components, we linearly model the observed distortion and obtain the cosmological constraint Ω m0.6σ8 = 0.46 ± 0.06. The amplitude of the linear redshift-space distortions relative to the galaxy overdensity field is dependent on galaxy properties and, for L* galaxies at redshift z = 0, we measure β(L*, 0) = 0.58 ± 0.08, and the amplitude of the overdensity fluctuations b(L *, 0)σ8 = 0.79 ± 0.03, marginalizing over the power spectrum shape parameters. Assuming a fixed power spectrum shape consistent with the full Fourier analysis produces very similar parameter constraints.
The marriage laws as found in the Canons of the Church of England.

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1986
Subjects: subject: Religion, General.

description: This study examines the marriage canons contained in the present canonical legislation of the Church of England. These canons, B30-B36, were promulgated in 1969 and may be found in The Canons of the Church of England: Canons Ecclesiastical Promulgated by the Convocations of Canterbury and York in 1964 and 1969. A broad sweep through English history shows that from the time of the Norman Conquest until the reign of Henry VIII, the canon law of the Western Church operated effectively in the country. Marriage was generally accepted as being of a religious nature and the temporal power left such matters to the Church. In 1533, Henry VIII gave statutory force to the universal ius commune, thereby creating a new body of national ecclesiastical law and through this act of legal fiction created a new legislator in matters canonical. The Church of England produced new codes of law for itself at different times in its history. These historical developments are traced and examined as are the various canons that applied to marriage. While the administration of canonical marriage law remained in the hands of churchmen, and Church courts alone remained competent to settle matrimonial cases, the question is posed: has the Church of England retained the canonical traditions concerning marriage which it had operated for a millenium prior to the Reformation?

description: Western Patagonia harbors unique and sparsely studied terrestrial ecosystems that are threatened by land use changes and exposure to basin-scale climatic variability. We assessed the performance of two satellite vegetation indices derived from MODIS–Terra, EVI (Enhanced Vegetation Index) and NDVI (Normalized Difference Vegetation Index), over the northern and southern sectors of the Chiloé Island System (CIS) to advance our understanding of vegetation dynamics in the region. Then we examined their time-varying relationships with two climatic indices indicative of tropical and extratropical influence, the ENSO (El Niño–Southern Oscillation) and the Antarctic Oscillation (AAO) index, respectively. The 17-year time series showed that only EVI captured the seasonal pattern characteristic of temperate regions, with low (high) phenological activity during Autumn-Winter (Spring–Summer). NDVI saturated during the season of high productivity and failed to capture the seasonal cycle. Temporal patterns in productivity showed a weakened seasonal cycle during the past decade, particularly over the northern sector. We observed a non-stationary association between EVI and both climatic indices. Significant co-variation between EVI and the Niño–Southern Oscillation index in the annual band persisted from 2001 until 2008–2009; annual coherence with AAO prevailed from 2013 onwards and the 2009–2012 period was characterized by coherence between EVI and both climate indices over longer temporal scales. Our results suggest that the influence of large-scale climatic variability on local weather patterns drives phenological responses in the northern and southern regions of the CIS. The imprint of climatic variability on patterns of primary production across the CIS may be underpinned by spatial differences in the anthropogenic modification of this ecosystem, as the northern sector is strongly modified by forestry and agriculture. We highlight the need for field validation of satellite indices around areas of high biomass and high endemism, located in the southern sector of the island, in order to enhance the utility of satellite vegetation indices in the conservation and management of austral ecosystems.

description: Wheat starch is composed of two populations of starch granules: large 'A' granules and small 'B' granules. A procedure for the separation of wheat starch into its component populations was developed. Digital image analysis showed that the resulting preparations contained 1% or less of the other granule population and were representative of the corresponding starch fraction in flour. The relative surface areas and volumes of these two types of starch granules were calculated and the results indicated that for an equal volume of starch granules, the small granules have 3.5--4.5 times the surface area of the large granules. The protein content of each population was determined from the nitrogen content. The small granules were found to contain 0.35% protein as compared to 0.15% protein in the large granules. Microspectrofluorometry was used as a means of indirectly measuring protein content and establishing the distribution of protein within the granules, before and after treatments to extract the protein. Extracted proteins from the soft wheat variety Fredrick were analyzed by SDS-PAGE to determine their distribution between the large and small starch granules. The large starch granules were found to contain one major protein and the small granules eight major proteins. These nine proteins were then isolated by electroelution and a partial characterization was carried out by determining amino acid compositions, N-terminal sequences, protease susceptibilities, peptide maps, and carbohydrate content. The results indicated that the nine proteins have several properties in common and they may be composed of similar structural units. In particular, the amino acid compositions, protease susceptibilities and peptide maps varied only slightly. However, there were a few differences among the proteins. Some of the them tested positive for carbohydrate, while others did not. N-terminal sequence analysis indicated that most of the N-termini were blocked, and the two distinct sequences obtained showed no homology to the primary structure of any known protein. One of the major differences between hard and soft wheats is the degree to which the starch granules are damaged during milling. The extent of damage can be visualized by certain stains, the most common being Congo Red. However, another related dye, Hessian Bordeaux, was found to stain damaged granules much more intensely. The maximum absorbance of starch granules stained with Hessian Bordeaux was more than five times that of starch granules stained with an equivalent concentration of Congo Red. Hessian Bordeaux is therefore a more useful stain than Congo Red for the microscopic detection of damaged starch granules.

description: In our current view of the Universe, galaxies form and evolve within dark matter halos. However, understanding how the invisible dark matter halos relate to galaxies and which galaxy properties are affected by them remains a complex task. This thesis explores a new methodology to measure the mass of dark matter haloes by studying lensing-induced deformations in the observed velocity fields of lensed galaxies. Overall, we demonstrate that the new approach provides ten-times more accurate measurements than previous methods, and allows to explore new important quantities in the formation and evolution of galaxies.

description: The surge of software agents has spurred interest in harnessing this technology with intelligent behavior. The empowerment of software agents attempts to relieve us of our mundane, laborious and often repetitive tasks. The aim of software agents is to offer intelligent automated assistance or guidance to users (Norman, 1994), machines, other software, or other software agents (Guha and Lenat, 1994), whenever requested and wherever employed. Intelligent Multi-Agent Based Virtual Gauges (IMAGES) is a software tool which provides a highly modular, customizable and easy to integrate solution for automating and enhancing the instrumentation of simulation output generation. The IMAGES system design is based on a software agent architecture to promote ease of use without compromising functionality. The integration of software agent technology relieves the user from having to manage every aspect of the back-end interface of a simulation environment. Furthermore, by decoupling the client application (i.e. the simulation or application program), from its back end interface, we achieve a virtual integration that enhances modularity, facilitates maintenance and enables distributed observation and monitoring. Both of these characteristics, the software agent based architecture and its virtual observation and monitoring capabilities, define the goals of IMAGES. Being native to the Microsoft Windows NT operating system, IMAGES takes advantage of the powerful advanced OLE communication facilities within the context of a true multi-tasking, multi-threaded, and graphical based operating system. Designed and implemented with object-oriented concepts from inception to completion, within the Microsoft Visual C++ development platform, the development and maintenance effort is minimized, thus facilitating future enhancements. Built on the base of the Windows 32-bit API, an industry standard for software development targeted at Microsoft Windows operating systems, future compatibility is assured. IMAGES represents a viable option for integrating state-of-the-art software instrumentation into existing simulation systems.

description: Ce travail a comme objet l'étude d'un cas réel et fort médiatisé d'utilisation abusive de la force à l'intérieur d'un corps policier. En décortiquant l'affaire Griffin-Gosset, nous tenterons de comprendre le fonctionnement du système de contrôle d'une modalité particulière d'illégalismes privilégiés (Acosta, 1988) en y incluant les éléments cruciaux inhérents au milieu policier qui, nous le croyons, possèdent une influence sur son fonctionnement. Nous aborderons, entre autre, les notions de risque, de sous-culture et d'autorité relatives au travail policier. Nous discuterons également de la légitimation de l'usage de la force et de l'ingérence de certaines influences dans le processus légal de contrôle de l'inconduite policière. Nous souhaitons donc ultérieurement dresser un portrait critique d'une réalité complexifiée, mais surtout empreinte d'ambiguïté qu'est le traitement de l'inconduite policière.

description: We measure moments of the galaxy count probability distribution function in the Two-degree Field Galaxy Redshift Survey (2dFGRS). The survey is divided into volume-limited subsamples in order to examine the dependence of the higher-order clustering on galaxy luminosity. We demonstrate the hierarchical scaling of the averaged p-point galaxy correlation functions, ξ̄p, up to p = 6. The hierarchical amplitudes, Sp = S2Sp-1, are approximately independent of the cell radius used to smooth the galaxy distribution on small to medium scales. On larger scales we find that the higher-order moments can be strongly affected by the presence of rare, massive superstructures in the galaxy distribution. The skewness S3 has a weak dependence on luminosity, approximated by a linear dependence on log luminosity. We discuss the implications of our results for simple models of linear and non-linear bias that relate the galaxy distribution to the underlying mass.

description: Background: The objectives of this study were (1) to identify age and sex trends in the disability burden of compensated work-related musculoskeletal disorders (MSDs) in Canada and Australia; and (2) to demonstrate a means of comparing workers’ compensation data internationally. Methods: All non-fatal, work-related MSD claims with at least one day of compensated time-loss were extracted for workers aged 15–80 during a 10-year period (2004–2013) using workers’ compensation data from five Canadian and eight Australian jurisdictions. Disability burden was calculated for both countries by sex, age group, and injury classification, using cumulative compensated time-loss payments of up to two years post-injury. Results: A total of 1.2 million MSD claims were compensated for time-loss in the Canadian and Australian jurisdictions during 2004–2013. This resulted in time-loss equivalent to 239,345 years in the Canadian jurisdictions and 321,488 years in the Australian jurisdictions. The number of time-loss years declined overall among male and female workers, but greater declines were observed for males and younger workers. The proportion of the disability burden grew among older workers (aged 55+), particularly males in the Canadian jurisdictions (Annual Percent Change [APC]: 7.2, 95% CI 6.7 to 7.7%) and females in the Australian jurisdictions (APC: 7.5, 95% CI 6.2 to 8.9%). Conclusions: The compensated disability burden of work-related MSDs is shifting towards older workers and particularly older females in Australia and older males in Canada. Employers and workers’ compensation boards should consider the specific needs of older workers to reduce injuries and time off work. Comparative research made possible through research-stakeholder partnerships offers a unique opportunity to use existing administrative data to identify long-term trends in disability burden. Future research can apply similar approaches for estimating long-term trends in occupational health.

description: A fast method for microplastic detection is thermal extraction desorption-gas chromatography/mass spectrometry (TED-GC/MS), which uses polymer-specific thermal decomposition products as marker compounds to determine polymer mass contents in environmental samples. So far, matrix impacts of different environmental matrices on TED-GC/MS performance had not yet been assessed systematically. Therefore, three solid freshwater matrices representing different aquatic bodies with varying organic matter contents were spiked with a total of eight polymers. Additionally, for the first time, the two biodegradable polymers polybutylene adipate terephthalate (PBAT) and polylactide (PLA) were analysed using TED-GC/MS. The methodological focus of this work was on detectability, quality of signal formation as well as realisation of quantification procedures and determination of the limit of detection (LOD) values. Overall, TED-GC/MS allowed the unambiguous detection of the environmentally most relevant polymers analysed, even at low mass contents: 0.02wt% for polystyrene (PS), 0.04wt% for the tyre component styrene butadiene rubber (SBR) and 0.2wt% for polypropylene (PP), polyethylene (PE) and PBAT. Further, all obtained LOD values were increased in all matrices compared to the neat polymer without matrix. The LOD of the standard polymers were increased similarly (PS: 0.21-0.34 (micro)g, SBR: 0.27-0.38 (micro)g, PP: 0.32-0.36 (micro)g, PMMA: 0.64-1.30 (micro)g, PET: 0.90-1.37 (micro)g, PE: 3.80-6.99 (micro)g) and their decompositions by radical scission processes were not significantly influenced by the matrices. In contrast, matrix-specific LOD increases of both biodegradable polymers PBAT (LOD: 1.41-7.18 (micro)g) and PLA (0.84-20.46 (micro)g) were observed, probably due to their hetero-functional character and interactions with the matrices. In conclusion, the TED-GC/MS performance is not solely determined by the type of the polymers but also by the composition of the matrix. © 2023 Wiley VCH GmbH
