Quantifying the variability in forest stream channel morphology
Creators: name: Trainor, Kristie Marie
Publisher: name: University of British Columbia
Year: 2009

description: Within forests, large variability exists in stream channel morphology. Recognizing this variability is important when attempting to characterize, quantify and/or compare stream channels. This point becomes extremely significant when considering the idea of "restoring" streams, a concept which seems to imply an ideal or "target" state. The idea of target states is intricately connected to stream channel variability, and it is this variability which is explored in this project. The study design incorporates comparison of stream channels, the drainage basins of which have similar biophysical, morphometric, and hydroclimatic characteristics. These characteristics are all known to affect or exert considerable influence on the processes which occur in forest streams. Numerous contingencies may also affect channel morphology locally. The key research objective is to determine the range of variability that these streams (under similar basic governing conditions and theoretically similar channel morphologies) possess. Nine stream channel characteristics (channel unit frequency, channel unit length, pool spacing, depth variability, width variability, LWD jam spacing, LWD volume, relative roughness, and average bankfull width [used as a surrogate for scale]) are measured in 12 old growth reaches and 6 managed reaches in the Queen Charlotte Islands and Vancouver Island. The data are split into six groups: all old-growth, uncoupled old-growth (stream is buffered from hillslopes by floodplain), coupled old-growth (stream receives material directly from adjacent hillslopes), selected old-growth, managed, and 'old-growth vs. managed'. Within each group, the stream channel characteristics can be analyzed by calculating the dissimilarity (a form of Euclidean distance measure) for all possible reach pair combinations. Frequency distributions based on the resulting dissimilarity values are constructed for each group. These distributions express the range of variability present in the streams analyzed. The resulting range of dissimilarity values precludes the definition of a single, ideal target state. However, the dissimilarity method of comparing stream channel reaches does enable definition of ranges of desirable or undesirable states and quantification of impact. Dissimilarity values for the 'all old-growth' reach pair group ranged from 2.73 to 10.92. For this reach pair group high dissimilarity was judged to be greater than or equal to 8.56. This value does not by any means constitute a regional reference dissimilarity value, as the sample size is simply too small. Reach pairs exhibiting high dissimilarity values tend to have significant differences in several key stream channel characteristics. These key stream channel characteristics vary between reach pairs. Those reaches consistently appearing in reach pairs with high dissimilarity values are considered 'severely impacted' (within this system of comparison).

description: We construct geometric representatives for the C^2/Z_n fractional branes in terms of branes wrapping certain exceptional cycles of the resolution. In the process we use large radius and conifold-type monodromies, and also check some of the orbifold quantum symmetries. We find the explicit Seiberg-duality which connects our fractional branes to the ones given by the McKay correspondence. We also comment on the Harvey-Moore BPS algebras.

description: We find exact solutions for a universal set of quantum gates on a scalable candidate for quantum computers, namely an array of two level systems. The gates are constructed by a combination of dynamical and geometrical (non-Abelian) phases. Previously these gates have been constructed mostly on non-scalable systems and by numerical searches among the loops in the manifold of control parameters of the Hamiltonian.

description: We study in depth the abundance discrepancy problem in H II regions, this time from a different perspective than the usual one: by studying the effect of the upper mass limit (M$_{\rm up}$) of the initial mass function (IMF) on the O, C, and He predicted by chemical evolution models for the Milky Way. We use abundances determined with the direct method (DM) and with the temperature independent method (TIM). We compare the predicted abundances at the present time with observations of Orion, M17, and M8 to determine the M$_{\rm up}$ value of the galactic IMF. From the DM abundances, the models predict an M$_{\rm up}$ = 25-45 M$_{\odot}$, while from the TIM, CEMs derive an M$_{\rm up}$ = 70-110 M$_{\odot}$. Spiral galaxies with the stellar mass and star formation rate of the MW are predicted to have an M$_{\rm up} \sim100$ M$_{\odot}$. These results support that abundances derived from the TIM are better than those derived from the DM.

description: A quarterly, partial-equilibrium vector-autoregression model of the U.S. durum wheat and pasta markets was estimated and simulated under three trade-barrier changes that are of potential relevance for the current round of WTO agricultural negotiations: a rise in the U.S. market-clearing durum wheat quantity from increased imports; a policy- or tariff- reduction-induced decline in U.S. durum wheat price; and a tariff-induced rise in U.S. pasta product prices. In response to each shock, an array of quarterly dynamic response characteristics are examined: response reaction times, direction and pattern of quarterly responses, response durations, response multipliers, and strength of durum/pasta market interrelationships.

description: Die vorliegende Arbeit beschäftigt sich mit den bodenmechanischen Ursachen von Gründungsschäden sowie Techniken zu deren Sanierung. Kernaufgabe ist es, einen Auswahlprozess zu entwickeln, mit dem im konkreten Schadensfall das zweckmäßigste technische Verfahren zur Sanierung bestimmt werden kann. Hierzu werden zunächst mögliche Schadensursachen katalogisiert. Anschließend werden die gegenwärtig in Deutschland gebräuchlichsten Sanierungstechniken analysiert und einander gegenübergestellt. Zur Ermittlung der geeignetsten Sanierungstechnik in einem realen Projekt wird ein allgemeiner zweistufiger Entscheidungsalgorithmus vorgeschlagen. Dieser setzt sich aus einem Entscheidungsbaum mit anschließender Nutzwertanalyse zusammen. Ergebnis des Algorithmus’ ist ein Ranking, welches die infrage kommenden Techniken nach ihrem Nutzen für die Sanierung ordnet. Anhand zweier Praxisbeispiele - dem Schloss Schwerin und der St. Jacobi-Schlosskirche in Osterode am Harz - wird abschließend die Wirkungsweise des Algorithmus demonstriert. Ergebnis der Arbeit ist, dass die Formulierung eines allgemeinen entscheidungsbaumes, der jedwede Eventualität einer speziellen Bauaufgabe berücksichtigt, nahezu unmöglich ist. Der entwickelte Entscheidungsbaum ist mitunter noch zu ungenau um die Auswahl an Techniken ausreichend einzuschränken. Die darum als zweite Stufe etablierte Nutzwertanalyse erwies sich als effiziente und transparente Entscheidungshilfe. Bei ihr ist jedoch die Gefahr einer subjektiven Beeinflussung der Entscheidung durch den Planer gegeben. In einem konkreten Projekt könnte durch eine Verfeinerung des Baumes seine Selektion wesentlich verbessert werden, so dass am Ende nur eine einzige Technik als zweckmäßigste ausgewiesen wird. Eine Nutzwertanalyse könnte in diesem Fall als zweite Stufe entfallen.

description: The Jaynes-Cummings (JC) model represents one of the simplest ways in which single qubits can interact with single photon modes, leading to profound quantum phenomena like superpositions of light and matter states. One system, that can be described with the JC model, is a single quantum dot embedded in a micropillar cavity. In this joint experimental and theoretical study we investigate such a system using four-wave mixing (FWM) micro-spectroscopy. Special emphasis is laid on the dependence of the FWM signals on the number of photons injected into the microcavity. By comparing simulation and experiment, which are in excellent agreement with each other, we infer that up to ~20 photons take part in the observed FWM dynamics. Thus we verify the validity of the JC model for the system under consideration in this non-trivial regime. We find that the inevitable coupling between the quantum dot exciton and longitudinal acoustic phonons of the host lattice influences the real time FWM dynamics and has to be taken into account for a sufficient description of the quantum dot-microcavity system. Performing additional simulations in an idealized dissipation-less regime, we observe that the FWM signal exhibits quasi-periodic dynamics, analog to the collapse and revival phenomenon of the JC model. In these simulations we also see that the FWM spectrum has a triplet structure, if a large number of photons is injected into the cavity.

description: Different industries throughout the world face a tough time confronting the pandemic of novel coronavirus (COVID-19), so does the hotel industry. Hence, this research attempts to determine the impact of the COVID-19 crisis on the hotel industry in terms of guest retention. The crisis which started in Wuhan, China (December 2019) has spread to the whole world and continues to spread. Although in newspapers, journals, and online media there are few published articles, they are mostly based on secondary data. This study is an attempt to examine the perceptions of hotel employees regarding the effect of COVID-19 on the hotel industry through qualitative analysis. Further, the study attempts to evaluate the crisis preparedness and steps taken to combat COVID-19, and eventually determine the positive outcome of the crisis. This paper presents an overview of the advent of COVID-19 in New Delhi, India, and more importantly, reports on the approaches that hotels employ to sustain during this difficult time. Through the in-depth interviews with senior employees in six hotels in the national capital city New Delhi, India (four interviews before the lockdown and two interviews during the lockdown). Empirical findings showed that at various phases of the crisis, hotels were taking different approaches to survive. The hotels were introducing strategies for guest retention to create stronger guest relationships. This paper presents the impact of this crisis on hotel employees and how the hotels are reacting to this crisis. The practical and theoretical implications of the study are discussed.

description: Interstellar dust and gas that enter the heliosphere provide us with important clues about both the heliosphere and the local interstellar medium (LISM). The picture we have of the Local Interstellar Cloud (LIC) from both \emph{in situ} detections and absorption line data presents questions that have important implications for the origins and evolution of the cloud. New detections of $^{60}$Fe on Earth in deep sea crusts and Antarctic snow cores provide evidence for the role of supernovae in shaping the LISM. We discuss our models for the evolution of the LIC inside the Local Bubble and possible explanations for the source of the supernova produced dust.

description: High-velocity galactic outflows, driven by intense bursts of star formation and black hole accretion, are invoked by current theories of galaxy formation to terminate star formation in the most massive galaxies and to deposit heavy elements in the intergalactic medium. From existing observational evidence on high-redshift galaxies, it is unclear whether such outflows are localized to regions of intense star formation just a few kiloparsecs in extent, or whether they instead have a significant impact on the entire galaxy and its surroundings. Here we present two-dimensional spectroscopy of a star-forming galaxy at redshift z=3.09 (seen 11.5 Gyr ago, when the Universe was 20 per cent of its current age): its spatially extended Ly-alpha emission appears to be absorbed by HI in a foreground screen covering the entire galaxy, with a lateral extent of at least 100 kpc and remarkable velocity coherence. It was plausibly ejected from the galaxy during a starburst several 1E8 yr earlier and has subsequently swept up gas from the surrounding intergalactic medium and cooled. This demonstrates the galaxy-wide impact of high-redshift superwinds.

description: The produce industry in Texas is currently faced with several issues that can potentially negatively effect fruit and vegetable participants. To combat these issues producers and other industry participants recently developed a task force to lead the produce industry through a detailed strategic planning process. This task force used a Framework for Industry Strategic Planning and Coordination (ISPC) developed by Lyford et al. as a model to guide its strategic planning efforts. Using this framework the task force was able to highlight the most significant issues affecting the industry and develop specific strategies and implementation plans to resolve these issues. This case study illustrates the application of ISPC and tests the overall usefulness of the framework.

description: The Perseus molecular cloud complex is a ~30pc long chain of molecular clouds most well-known for the two star-forming clusters NGC1333 and IC348 and the well-studied outflow source in B5. However, when studied at mid- to far-infrared wavelengths the region is dominated by a ~10pc diameter shell of warm dust, likely generated by an HII region caused by the early B-star HD278942. Using a revised calibration technique the COMPLETE team has produced high-sensitivity temperature and column-density maps of the Perseus region from IRAS Sky Survey Atlas (ISSA) 60 and 100um data. In this paper, we combine the ISSA based dust-emission maps with other observations collected as part of the COMPLETE Survey, along with archival H-alpha and MSX observations. Molecular line observations from FCRAO and extinction maps constructed by applying the NICER method to the 2MASS catalog provide independent estimates of the ``true'' column-density of the shell. H-alpha emission in the region of the shell confirms that it is most likely an HII region located behind the cloud complex, and 8um data from MSX indicates that the shell may be interacting with the cloud. Finally, the two polarisation components previously seen towards background stars in the region can be explained by the association of the stronger component with the shell. If confirmed, this would be the first observation of a parsec-scale swept-up magnetic field.

Sample A shows large negative magnetoresistance around the charged ordering (CO) temperature with magnetic anomalies seen in the temperature dependent resistivity,magnetization and M-H hysteresis loops. Sample B shows a smooth insulating behavior with no thermal hysteresis in the resistivity and with a small positive magnetoresistance. cac and cdc show multiple features associated with a frustrated magnetic order (helical) due to competing ferro- and antiferromagnetic interactions. The competing effects of ferro- and antiferromagnetic phases extend up to T ~ 230 K revealing a new high temperature scale in this system. These observations are discussed in the context of magnetic interactions associated with the varying Fe4+/Fe3+ ratio.

description: This paper uses a two-good specific factors model to derive a relationship between international trade, land degradation, and welfare. Because developing countries enjoy comparative advantage in agriculture, they will export agricultural goods. We found that trade could lower steady state land quality and welfare. We conclude that poor resource management undermines the conventional gains from globalization.

description: Users of agricultural markets frequently need to establish accurate representations of expected future volatility. The fact that range-based volatility estimators are highly efficient has been acknowledged in the literature. However, it is not clear whether using range-based data leads to better risk management decisions. This paper compares the performance of GARCH models, range-based GARCH models, and log-range based ARMA models in terms of their forecasting abilities. The realized volatility will be used as the forecasting evaluation criteria. The conclusion helps establish an efficient forecasting framework for volatility models.

description: India is full of biodiversity so are all its states and union territories. Many states are larger than many other countries of Europe and Africa whereas others are too small in terms of size, population, socio-economic and ecological diversity. It is possible to analyze the tourism efficiency of all Indian states and union territories to evaluate whether the states and union territories are harvesting maximum tourist arrivals by managing their diverse range of physical attraction features and human resources effectively. This study measures the tourism efficiency for all Indian states and union territories based on relevant national resources, economic, and deterrent variables derived from secondary data sources. The findings of the study confirm that the smaller states are performing better than the larger states as far as the environmental aspects and economic aspects are considered. The regression results also confirm that the area and per capita Gross State Domestic Product both are playing a signifficant role in shaping the tourism eciency of the states of India. This perspective of ranking states and union territories adds signifficant inputs for future tourism planning and policy issues with certain important comparisons and recommendations.

description: The possibility that the Gallium data effectively indicates a time modulation of the solar active neutrino flux in possible connection to solar activity is examined on the light of spin flavour precession to sterile neutrinos as a subdominant process in addition to oscillations. We distinguish two sets of Gallium data, relating them to high and low solar activity. Such modulation affects principally the low energy neutrinos ($pp$ and $^7 Be$) so that the effect, if it exists, will become most clear in the forthcoming Borexino and LENS experiments and will provide evidence for a neutrino magnetic moment. Using a model previously developed, we perform two separate fits in relation to low and high activity periods to all solar neutrino data. These fits include the very recent charged current spectrum from the SNO experiment. We also derive the model predictions for Borexino and LENS experiments.

description: Für den Bauingenieur gehört der Tunnelbau auf Grund seiner Komplexität zu den interessantesten, faszinierendsten, zugleich aber auch zu den schwierigsten Aufgaben in seinem Tätigkeitsbereich. Bei der Planung eines Tunnelbauwerkes stehen mehrere Faktoren in direkter Beziehung, wie beispielsweise die vorherrschenden Gebirgsverhältnisse, die gewählte Konstruktion und das angewendete Bauverfahren. Durch die komplexe Wechselwirkung von Bauwerk und Gebirge unterscheidet sich der Tunnelbau maßgeblich von den anderen anspruchsvollen Bauingenieurdisziplinen wie Brücken-, Tief- und Industriebau sowie dem allgemeinen Hochbau. Ein Charakteristikum von Tunneln ist das Durchfahren stark wechselnder Gebirgsverhältnisse, die zum Zeitpunkt der Planung nur grob und ohne scharfe qualitative und quantitative Abgrenzung bekannt sind. Da aufgrund ihrer tektonischen Entstehungsgeschichte die meisten Gebirge heterogen aufgebaut sind, müssen bei der Bemessung von Tunnelbauwerken die Streuungen der geologischen und gebirgsmechanischen Parameter berücksichtigt werden, die beispielsweise aus Trennflächen, wie Schichtungen und Klüftungen resultieren. Ziel dieser Diplomarbeit ist es, in Zusammenarbeit mit der Praxis die wesentlichsten Schwierigkeiten beim Bau des Schmücketunnels zu eruieren und anschließend eine Empfehlung für weitere Baumaßnahmen auszusprechen. Hierzu dienen die Planungsunterlagen des derzeit in Ausführung befindlichen Tunnels, die im Zuge der Bearbeitung dieser Arbeit ausgewertet und aufgearbeitet werden. Des Weiteren werden Varianten für die Beherrschung der komplexen Grundwasserverhältnisse diskutiert und diese einer technisch-wirtschaftlichen Bewertung in Form eines Variantenvergleiches unterzogen. Anschließend folgt die Nennung der Vorzugsvariante. Darüber hinaus erfolgt in der vorliegenden Arbeit eine Analyse der beim Schmücketunnel angewendeten Messtechnik. Daraus resultierend sollen 0 Einleitung 2 Empfehlungen hinsichtlich der messtechnischen Überwachung für die Errichtung zukünftiger Tunnelbauwerke gegeben werden. In einem weiteren Kapitel werden Bemessungsansätze eines repräsentativen Querschnittes diskutiert und schließlich eine Standsicherheitsanalyse für die Tunnelinnenschale durchgeführt. Auf Grund der großen Bandbreite der in den Bodengutachten angegebenen Gebirgskennwerte erfolgt die Berechnung verschiedener Varianten bezüglich der erforderlichen Bewehrungsmengen. Um eine Balance zwischen wissenschaftlichem Arbeiten und den Erfahrungen aus der Praxis zu schaffen, sehe ich die Unterstützung durch die Professur Grundbau der Bauhaus-Universität Weimar sowie durch das Unternehmen DEGES in Berlin als grundlegende Voraussetzung für die inhaltliche Vollständigkeit der vorliegenden Diplomarbeit an.

description: Fog Radio Access Network (F-RAN) exploits cached contents at edge nodes (ENs) and fronthaul connection to the cloud for content delivery. Assuming dedicated fronthaul links between cloud and each EN, previous works focused on analyses of F-RANs using offline or online caching depending whether the content popularity is time-invariant or time-variant. Extension has been done for multicast fronthaul link connecting cloud to only two ENs and time-invariant popularity. In contrast, the scope of this work is on the case where multicast fronthaul link connects arbitrary number of ENs to the cloud and content popularity is time-variant. Normalized Delivery Time (NDT) is used as a performance measure and by investigating proactive online caching, analytical results reveal that the power scaling of fronthaul transmission sets a limit on the performance of F-RAN.

It contains an implementation of the product algebra, the derivative properties, series expansion and numerical evaluation. The analytic continuation has been treated carefully, allowing the user to keep the control over the definition of the sign of the imaginary parts. Many options enables the user to adapt the behavior of the package to his specific problem.

description: Let $(N,\R,θ)$ be a centrally ergodic W* dynamical system. When $N$ is not a factor, we show that, for each $t\not=0$, the crossed product induced by the time $t$ automorphism $θ_t$ is not a factor if and only if there exist a rational number $r$ and an eigenvalue $s$ of the restriction of $θ$ to the center of $N$, such that $rst=2π$. In the C* setting, minimality seems to be the notion corresponding to central ergodicity. We show that if $(A,\R,α)$ is a minimal unital C* dynamical system and $A$ is either prime or commutative but not simple, then, for each $t\not=0$, the crossed product induced by the time $t$ automorphism $α_t$ is not simple if and only if there exist a rational number $r$ and an eigenvalue $s$ of the restriction of $α$ to the center of $A$, such that $rst=2π$.

description: Bt maize in Kenya is promising biotechnology innovation for poor households. Econometric prediction from a trait-based model of variety adoption indicates that the choice of host variety has equity and efficiency implications related to heterogeneity in maize growing environments and pest pressures, as well as the differences among farm households in terms of wealth, income, and market access.
Assembly and intracellular trafficking of the B cell antigen receptor in a mutant B cell lymphoma, WEHI 88.1
Creators: name: Escribano, Jessica
Publisher: name: University of British Columbia
Year: 2009

description: Mutations that affect the synthesis of receptor subunits or that interfere with protein folding may lead to ER retention of unassembled receptors. This retention process is part of the secretory pathway's "quality control" mechanism, which consists of a variety of molecular chaperones and enzymes that assist nascent proteins in their folding, assembly, and post-translational modification. The B cell antigen receptor (BCR) is an oligomeric protein that undergoes a complex, stepwise, assembly process. The BCR consists of an antigen-binding component, mlgM (containing two immunoglobulin heavy (H) chains and two light (L) chains), and a signaling component, Ig-α/Ig-β. Both parts of the BCR must correctly assemble and associate with each other to leave the ER. If one of more subunits of the BCR is missing or defective, the entire receptor is retained and targeted for degradation (Matsuuchi et al., 1992). In the current study, we have characterized the BCR expressed by WEHI 88.1, a B lymphoma mutant. WEHI 88.1 expresses all four chains of the BCR, however, they are retained intracellularly in a pre-Golgi compartment. Our studies revealed that WEHI 88.1 mlgM assembly was defective, likely due to limiting amounts of K L chain. As a consequence of limiting amounts of K L chain, completely assembled mlgM composed of two H chains and two L chains (H2L2) was not detected in the mutant. In addition, pulse chase analysis indicated that K L chain turnover in the mutant differed from that in wild type cells. In contrast, the Ig-α/Ig-β part of the receptor assembled normally and associated with the mlgM present in the WEHI 88.1 cell line. This study has identified a key defect in the assembly of the BCR in mutated WEHI 88.1 cells and this mutant can serve as a tool for the future studies of receptor: chaperone interactions during the assembly process.
All-electron Exact Exchange Treatment of Semiconductors: Effect of Core-valence Interaction on Band-gap and $d$-band Position

description: Exact exchange (EXX) Kohn-Sham calculations within an all-electron full-potential method are performed on a range of semiconductors and insulators (Ge, GaAs, CdS, Si, ZnS, C, BN, Ne, Ar, Kr and Xe). We find that the band-gaps are not as close to experiment as those obtained from previous pseudopotential EXX calculations. Full-potential band-gaps are also not significantly better for $sp$ semiconductors than for insulators, as had been found for pseudopotentials. The locations of $d$-band states, determined using the full-potential EXX method, are in excellent agreement with experiment, irrespective of whether these states are core, semi-core or valence. We conclude that the inclusion of the core-valence interaction is necessary for accurate determination of EXX Kohn-Sham band structures, indicating a possible deficiency in pseudopotential calculations.

We find that the calculated profiles of the loss of sigma- and pi-band holes in these two systems as a function of impurity concentration are in qualitative agreement with experiments, as expected. We also describe its implications vis-a-vis superconductivity in Mg_{1-x}Al_{x}B_{2} and Mg(B_{1-y}C_{y})_{2}.

Large spin gaps in half metals MN4 (M=Mn, Fe, Co) with N2 dimers

description: We predict that cubic MN4 (M=Mn, Fe, Co) are all half metals with the largest spin gap up to ~ 5 eV. They possess robust ferromagnetic ground states with the highest Curie temperature up to ~ 103 K. Our calculations indicate these compounds are energetically favored, dynamically and mechanically stable. It is proposed that self-doping of these 3d transition metals occurs in MN4 due to the reduction in electronegativity of N2 dimers. This model can well explain the calculated integer magnetic moments, large spin gaps of MN4 and semiconducting behavior for NiN4 as well. Our results highlight the difference in electronegativity between transition metal ions and non-metal entities in forming half metals and the role of N2 dimer in enlarging the spin gaps for nitride half metals.

description: Austritte aus Kinder- und Jugendheimen und Pflegefamilien sind bedeutsame Übergänge im Leben von Kindern und Jugendlichen, die mit tiefgreifenden biografischen Veränderungen einhergehen können. Während der Übergang junger Erwachsener in die Selbstständigkeit (Leaving Care) in den vergangenen Jahren viel Aufmerksamkeit erfahren hat, ist die Rückkehr in die Herkunftsfamilie im Fachdiskurs bisher weitgehend unberücksichtigt geblieben. Im Workshop werden Spannungsfelder, Herausforderungen und Unsicherheiten, die mit Rückkehrfragen und Rückkehrprozessen verbunden sind, besprochen. Darauf aufbauend wird diskutiert, wie die fachliche Abwägung verschiedener Kinderinteressen unter Einbezug der Kinder und Jugendlichen gestaltet werden kann.

description: Traceability exists in many food supply chains for valid economic reasons, one of which is improving food safety and quality. Some politicians and consumer groups are calling for increased identity preservation in systems where traceability has not yet been adopted. In this paper, we explore the implications of adding traceability to a food supply chain that already includes an inspection protocol. Our objective is to determine whether the addition of traceability will change the feasibility of a market for safer food and whether it will change the allocation of profits between producers and processors. We find that the addition of traceability to this system does influence whether or not the market will be feasible. If traceability is too high, then processors will not demand safer food, and if traceability is too low, then producers will not deliver safer food. We also show that the feasibility of the market depends on the sensitivity of the test used to inspect food

description: The fascinating physics underlying eta and eta-prime mesons can be studied theoretically and experimentally in various contexts. In this presentation we want to turn our attention to two important uncorrelated aspects of this vivid research field which provide yet unexpected challenges or surprises. First we discuss open questions in the theoretical treatment of Coulomb-interaction in the context of reaction processes like p p --> p p eta. Then we review eta - eta-prime and sigma(600) - f_0(980) mixing in the U(3) x U(3) Linear Sigma Model and extract information on eta - eta-prime mixing and the K*0(800) resonance from meson-meson scattering.
