Monotone schemes for degenerate and non-degenerate parabolic problems
Creators: name: Limic, Mirna
Publisher: name: University of British Columbia
Year: 2011

description: This thesis analyses several monotone schemes for degenerate second order parabolic PDEs over two-dimensional domains which is in most cases equal (0, l )2 . For such problems the degeneracy means that in addition to the axis spanned by the standard basis vectors, there exists another pair of orthogonal cordinate axes such that the spatial difference operator is of the second order in one of the directions, and of the first order in the remaining directions. The direction of one axis along which the spatial difference operator is of the second order we call the direction of diffusion. The thesis considers only constant coefficient PDE's and therefore the degeneracy can be easily determined by solving the eigenvalue problem for diffusion tensor. We analyse the impact of the direction of diffusion on the convergence of a scheme. Previous work on a second order elliptic problem has shown that central differences taken in the direction of diffusion produce a convergent scheme, wherease disalignment between the two result in non-convergent schemes. One of our aims was to check the validity of this finding and possibly improve the construction of schemes. As a result we present a novel approach to building monotone schemes from the diffusion tensor by taking spatial step sizes of different length in order to align the second order central differences with the direction of diffusion. We give a step by step algorithm and supply all of the findings. Our findings are based on MATLAB m file, and C language implementations.

description: The appearance of half-quantized thermal Hall conductivity in $α$-RuCl$_3$ in the presence of in-plane magnetic fields has been taken as a strong evidence for Kitaev spin liquid. Apart from the quantization, the observed sign structure of the thermal Hall conductivity is also consistent with predictions from the exact solution of the Kitaev model. Namely, the thermal Hall conductivity changes sign when the field direction is reversed with respect to the heat current, which is perpendicular to one of the three nearest neighbor bonds on the honeycomb lattice. On the other hand, it is almost zero when the field is applied along the bond direction. Here, we show that such a peculiar sign structure of the thermal Hall conductivity is a generic property of the polarized state in the presence of in-plane magnetic-fields. In this case, thermal Hall effect arises from topological magnons with finite Chern numbers and the sign structure follows from the symmetries of the momentum space Berry curvature. Using a realistic spin model with bond-dependent interactions, we show that the thermal Hall conductivity can have a magnitude comparable to that observed in the experiments. Hence the sign structure alone cannot make a strong case for Kitaev spin liquid. The quantization at very low temperatures, however, will be a decisive test as the magnon contribution vanishes in the zero temperature limit.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: Both the set of quantum states and the set of classical states described by symplectic tomographic probability distributions (tomograms) are studied. It is shown that the sets have common part but there exist tomograms of classical states which are not admissible in quantum mechanics and vica versa, there exist tomograms of quantum states which are not admissible in classical mechanics. Role of different transformations of reference frames in phase space of classical and quantum systems (scaling and rotation) determining the admissibility of the tomograms as well as the role of quantum uncertainty relations is elucidated. Union of all admissible tomograms of both quantum and classical states is discussed in context of interaction of quantum and classical systems. Negative probabilities in classical mechanics and in quantum mechanics corresponding to the tomograms of classical states and quantum states are compared with properties of nonpositive and nonnegative density operators, respectively.

description: The recent 9-billion-gallon increase in corn-based ethanol production, which resulted from a combination of rising gasoline prices and a suite of Federal bioenergy policies, provides evidence of how farmers altered their land-use decisions in response to increased demand for corn. As some forecasts had suggested, corn acreage increased mostly on farms that previously specialized in soybeans. Other farms, however, offset this shift by expanding soybean production. Farm-level data reveal that the simultaneous net expansion of corn and soybean acreage resulted from a reduction in cotton acreage, a shift from uncultivated hay to cropland, and the expansion of double cropping (consecutively producing two crops of either like or unlike commodities on the same land within the same year).

description: An economic analysis was conducted involving wheat and grain sorghum production systems that affect carbon dioxide emissions and sequester soil carbon. Parameters examined were expected net returns, changes in net carbon sequestered and the value of carbon credits necessary to equate net returns from systems that sequester more carbon to those that sequester less with and without adjustments for CO2 emissions from production inputs. Evaluations were based on experiment station cropping practices, yield, and soil carbon data for continuously cropped and rotated wheat and grain sorghum produced with conventional and no-tillage. No-till had lower net returns because of lower yields and higher overall costs. Both crops produced under no-till had higher annual soil C gains than under conventional tillage. However, no-till systems had higher total atmospheric emissions of C from production inputs. The differences were relatively small. The C values estimated in this study that would equate net returns of notillage to conventional tillage range from $7.82 to $58 .69/ton/yr when C emissions from production inputs were subtracted from soil carbon sequestered and $7.79 to $54.99/tonlyr when atmospheric emissions were not considered.

description: In acoustic scene classification (ASC), acoustic features play a crucial role in the extraction of scene information, which can be stored over different time scales. Moreover, the limited size of the dataset may lead to a biased model with a poor performance for records from unseen cities and confusing scene classes. In order to overcome this, we propose a long-term wavelet feature that requires a lower storage capacity and can be classified faster and more accurately compared with classic Mel filter bank coefficients (FBank). This feature can be extracted with predefined wavelet scales similar to the FBank. Furthermore, a novel data augmentation scheme based on generative adversarial neural networks with auxiliary classifiers (ACGANs) is adopted to improve the generalization of the ASC systems. The scheme, which contains ACGANs and a sample filter, extends the database iteratively by splitting the dataset, training the ACGANs and subsequently filtering samples. Experiments were conducted on datasets from the Detection and Classification of Acoustic Scenes and Events (DCASE) challenges. The results on the DCASE19 dataset demonstrate the improved performance of the proposed techniques compared with the classic FBank classifier. Moreover, the proposed fusion system achieved first place in the DCASE19 competition and surpassed the top accuracies on the DCASE17 dataset.

description: The cosmic structure formed from Baryon Acoustic Oscillations (BAO) in the early universe is imprinted in the galaxy distribution observable in large scale surveys, and is used as a standard ruler in contemporary cosmology. BAO are typically detected as a preferential length scale in two point statistics, which gives little information about the location of BAO structures in real space. The aim of the algorithm described in this paper is to find probable centers of BAO in the cosmic matter distribution. The algorithm convolves the three dimensional distribution of matter density with a spherical shell kernel of variable radius placed at different locations. The locations that correspond to the highest values of the convolution correspond to the probable centers of BAO. This method is realized in an open-source, computationally efficient algorithm. We describe the algorithm and present the results of applying it to the SDSS DR9 CMASS survey and associated mock catalogs. A detailed performance study demonstrates the algorithm's ability to locate BAO centers, and in doing so presents a novel detection of the BAO scale in galaxy surveys.

description: Exosomes are nanovesicles secreted by various cells and contain biomolecular cargoes such as lipids, proteins and nucleic acids, they mediate intercellular communication and are a key feature of multicellular organisms and can induce communication through direct cell-to-cell contact or through the transport of secreted molecules. they play a critical role in various biological processes. A wealth of research documents the enormous therapeutic potential of exosomes for disorders including chronic wound healing, kidney disease, neurological damage, cardiovascular dysfunction, viral pathogenesis, immune response, pregnancy and Covid disease. At the same time, the isolation of exosomes is considered important, where ultracentrifugation is considered the gold standard, as it is the optimal method for the separation of small particles, especially exosomes, which has contributed to their study. In this thesis, the data and research on the functions of exosomes and their role in the human body are presented. At the same time, the isolation methods of exosomes and their therapeutic applications in the various disorders of the human body are described.

description: Let W be the number of points in (0,t] of a stationary finite-state Markov renewal point process. We derive a bound for the total variation distance between the distribution of W and a compound Poisson distribution. For any nonnegative random variable ζ, we construct a ``strong memoryless time'' \hat ζsuch that ζ-t is exponentially distributed conditional on {\hat ζ\leq t, ζ>t}, for each t. This is used to embed the Markov renewal point process into another such process whose state space contains a frequently observed state which represents loss of memory in the original process. We then write W as the accumulated reward of an embedded renewal reward process, and use a compound Poisson approximation error bound for this quantity by Erhardsson. For a renewal process, the bound depends in a simple way on the first two moments of the interrenewal time distribution, and on two constants obtained from the Radon-Nikodym derivative of the interrenewal time distribution with respect to an exponential distribution. For a Poisson process, the bound is 0.

description: The quasielastic charged-current (CC) tau neutrino (antineutrino)-nucleus scattering is considered. The dependence of tau polarization on nuclear-structure effects is discussed in detail. The description of the nucleus is based on the Mean-Field Theory (MFT). The ground state of nucleus is described using the Relativistic Fermi Gas model (FG). The effective mass is introduced as well as the ring Random Phase Approximation (RPA) effects are taken into account in the framework of relativistic meson-nucleon model. The Local Density Approximation (LDA) is used for the argon nucleus, having in mind possible application to the ICARUS experiment. The discussion concentrates on the threshold region where the $τ^-$ can be unpolarized and the nuclear effects play an important role.

description: We present the Hubble imaging Probe of Extreme Environments and Clusters (HiPEEC) survey. We fit HST NUV to NIR broadband and H$α$ fluxes, to derive star cluster ages, masses, extinctions and determine the star formation rate (SFR) of 6 merging galaxies. These systems are excellent laboratories to trace cluster formation under extreme gas physical conditions, rare in the local universe, but typical for star-forming galaxies at cosmic noon. We detect clusters with ages of 1-500 Myr and masses that exceed $10^7$ M$_\odot$. The recent cluster formation history and their distribution within the host galaxies suggest that systems like NGC34, NGC1614, NGC4194 are close to their final coalescing phase, while NGC3256, NGC3690, NGC6052 are at an earlier/intermediate stage. A Bayesian analysis of the cluster mass function in the age interval 1-100 Myr provides strong evidence in 4 of the 6 galaxies that an exponentially truncated power law better describes the observed mass distributions. For two galaxies, the fits are inconclusive due to low number statistics. We determine power-law slopes $β\sim-1.5$ to $-2.0$, and truncation masses, M$_c$, between $10^6$ and a few times $10^7$ M$_\odot$, among the highest values reported in the literature. Advanced mergers have higher M$_c$ than early/intermediate merger stage galaxies, suggesting rapid changes in the dense gas conditions during the merger. We compare the total stellar mass in clusters to the SFR of the galaxy, finding that these systems are among the most efficient environments to form star clusters in the local universe.

Interactions between climate and the marine nitrogen cycle on glacial-interglacial timescales
Creators: name: Galbraith, Eric Douglas
Publisher: name: University of British Columbia
Year: 2010

description: Nitrogen is a principal component of living organisms and comprises the majority of the atmosphere, yet the scarcity of biologically reactive nitrogen in the ocean limits growth and appears to have varied with past changes in physical climate. This thesis takes a multi-faceted approach, including fine-scale sediment analysis, modern field observations and global numerical modeling, to contribute an integrated view of the marine nitrogen cycle and its climatic sensitivity. Nitrogen bound in diatom frustules, extracted from laminated sediments of the Guaymas Basin, has greater seasonal δ¹⁵N variability than corresponding bulk sediment. Downslope transport of frustules from the shelf contributes δ¹⁵N -depleted nitrogen, while pelagic diatom frustules display great sensitivity to seasonal growing conditions. Bulk sedimentary δ¹⁵N represents a reliable integrated monitor of the local nitrogen substrate. Records of bulk sedimentary δ¹⁵N from the subarctic Pacific reflect the tripartite imprints of diagenesis, variable nitrate utilization and changes in δ¹⁵N -nitrate. Modern subsurface δ¹⁵N -nitrate is homogenous across the open subarctic Pacific. Diagenesis introduces δ¹⁵N -enrichments at core tops and there is a gradual decrease of δ¹⁵N with burial. The Gulf of Alaska record does not sample HNLC waters, but records changes in δ¹⁵N -nitrate and diagenesis. This is used to correct for regional 8I 5Nnitrate variability, revealing rapid increases in nitrate utilization, likely due to Fe fertilization, in the western subarctic Pacific during glacial periods. The δ¹⁵N -nitrate record suggests denitrification may have occurred in the deep ocean during the last glacial maximum, and almost certainly in the upper water column of the deglacial subarctic Pacific. A global compilation of δ¹⁵N records evokes co-ordinated changes in denitrification throughout the global thermocline, implying large increases in aggregate denitrification rate, matched by changes in N₂ fixation, under warming conditions. A global, physically-driven modulation of subsurface oxygen concentrations is proposed as the primary relevant forcing on glacial-interglacial timescales. Simple schemes for denitrification and N₂ fixation, based on widely accepted ecological principles, are quantified and embedded in a General Circulation Model of intermediate complexity. The model highlights the competition between diazotrophs and other phytoplankton for phosphorus as a key element of the marine biosphere. The model confirms a pronounced sensitivity of denitrification rates to the physical climate state, with more rapid rates of nitrogen cycling and expanded nitrogen limitation under warmer climates.

description: Coronavirus disease (COVID-19) spread forecasting is an important task to track the growth of the pandemic. Existing predictions are merely based on qualitative analyses and mathematical modeling. The use of available big data with machine learning is still limited in COVID-19 growth prediction even though the availability of data is abundance. To make use of big data in the prediction using deep learning, we use long short-term memory (LSTM) method to learn the correlation of COVID-19 growth over time. The structure of an LSTM layer is searched heuristically until the best validation score is achieved. First, we trained training data containing confirmed cases from around the globe. We achieved favorable performance compared with that of the recurrent neural network (RNN) method with a comparable low validation error. The evaluation is conducted based on graph visualization and root mean squared error (RMSE). We found that it is not easy to achieve the same quantity of confirmed cases over time. However, LSTM provide a similar pattern between the actual cases and prediction. In the future, our proposed prediction can be used for anticipating forthcoming pandemics.

description: Food safety technology can increase a company’s capacity to prevent a foodborne contamination. A food safety audit—a quality control tool in which an auditor observes whether a plant’s processing practices and technologies are compatible with good food safety practices—can indicate how effectively food safety technology is being used. Fast food restaurants, grocery stores, and other major customers of meat and poultry processing plants conduct their own audits or hire auditors to assess the soundness of a plant’s processing operation. Meat and poultry plants can also audit themselves as a way to help maintain process control. In this report, we document the extent of food safety audits in meat and poultry processing plants. We also examine the associations between the use of audits and plant size, firm structure, and food safety technology use. Results show that larger plants, plants subject to food safety audits, and plants that are part of a multiplant firm use more food safety technology than other plants. Plants subject to both plant-hired and customer-hired audits had greater technology use than single (plant- or customer-hired) audit plants.

description: We present the results of study of the Galactic candidate luminous blue variable Wray 15-906, revealed via detection of its infrared circumstellar shell (of \approx2 pc in diameter) with the Wide-field Infrared Survey Explorer and the Herschel Space Observatory. Using the stellar atmosphere code CMFGEN and the Gaia parallax, we found that Wray 15-906 is a relatively low-luminosity, log(L/Lsun)\approx5.4, star of temperature of 25\pm2 kK, with a mass-loss rate of \approx3\times10^{-5} Msun/yr, a wind velocity of 280\pm50 km/s, and a surface helium abundance of 65\pm2 per cent (by mass). In the framework of single star evolution, the obtained results suggest that Wray 15-906 is a post-red supergiant star with initial mass of \approx26\pm2 Msun and that before exploding as a supernova it could transform for a short time into a WN11h star. Our spectroscopic monitoring with the Southern African Large Telescope (SALT) does not reveal significant changes in the spectrum of Wray 15-906 during the last 8 yr, while the V-band light curve of this star over years 1999--2019 shows quasi-periodic variability with a period of \approx1700 d and an amplitude of \approx0.1 mag. We estimated the mass of the shell to be 2.9\pm0.5 Msun assuming the gas-to-dust mass ratio of 200. The presence of such a shell indicates that Wray 15-906 has suffered substantial mass loss in the recent past. We found that the open star cluster C1128-631 could be the birth place of Wray 15-906 provided that this star is a rejuvenated product of binary evolution (a blue straggler).

description: Since the epoch of cosmic star formation peak at $z \sim 2$, most of it is obscured in high mass galaxies, while in low mass galaxies the radiation escapes unobstructed. During the reionization epoch, the presence of evolved, dust obscured galaxies are a challenge to galaxy formation and evolution models. By means of a chemodynamical evolution model, we investigate the star formation and dust production required to build up the bulk of dust in galaxies with initial baryonic mass ranging from $7.5 \times 10^{7}$~M$_\odot$ to $2.0 \times 10^{12}$~M$_\odot$. The star formation efficiency was also chosen to represent the star formation rate from irregular dwarf to giant elliptical galaxies. We adopted a dust coagulation efficiency from \citep[][Case A]{dwek1998evolution} as well as a lower efficiency one (Case B), about five times smaller than Case A. All possible combination of these parameters was computed, summing forty different scenarios. We find that in high stellar formation systems the dust accretion in ISM rules over stellar production before the star formation peak, making these systems almost insensible to dust coagulation efficiency. In low star formation systems, the difference between Case A and B lasts longer, mainly in small galaxies. Thus, small irregular galaxies should be the best place to discriminate different dust sources. In our observational sample, taken from the literature, dust-to-gas ratio tends to be more spread only than dust mass, for both stellar mass and star formation rate. Dust-to-gas vs. dust-to-star diagram is a good tracer for both galaxy and dust evolution, due to the link between gas, star, dust and star formation rate. However, the model do not constrain simultaneously all this quantities. The new generation facilities (such as JWST, ELT, VLT and SPICA) will be indispensable to constrain dust formation across the cosmic time.

description: This study examined the economic potential with and without carbon credit payments of two crop and tillage systems in South Central Kansas that could reduce carbon dioxide emissions and sequester carbon in the soil. Experiment station cropping practices, yield data, and soil carbon data for continuously cropped wheat and grain sorghum produced with conventional tillage and no-tillage from1986 to 1995 were used to determine soil carbon changes and to develop enterprise budgets to determine expected net returns for a typical dryland farm in South Central Kansas. No-till had lower net returns because of lower yields and higher overall costs. Both crops produced under no-till had higher annual soil C gains than under conventional tillage. Carbon credit payments may be critical to induce farm managers to use cropping practices, such as no-till, that sequester soil carbon. The carbon credit payments needed will be highly dependent on cropping system production costs, especially herbicide costs, which substitute for tillage as a means of weed control. The C values estimated in this study that would provide an incentive to adopt no-tillage range from $0 to $95.991ton/year, depending upon the assumption about herbicide costs. In addition, if producers were compensated for other environmental benefits associated with no-till, carbon credits could be reduced.

description: Irisin is a hormone that is offered to be a hopeful remedial target in obesity and type 2 diabetes. It has received striking attention recently, whereas, the interactions between exercise training and irisin are still unclear. Therefore, this systematic review and meta-analysis investigated the impacts of exercise interventions on circulating irisin in adults. A systematic search was conducted in PubMed, CINAHL, MEDLINE, Cochrane, Google Scholar, and Scopus up to July 15, 2021. Twenty-four studies, which assessed a total of 921 participants were included and analyzed using a random-effects model to estimate weighted mean differences (MD) with 95 % confidence intervals (CI). Overall, data revealed that exercise training significantly increased circulating irisin (MD: 0.01, 95 % CI: 0.00, 0.01, p = 0.005), and declined insulin (MD: -2.09, 95 % CI: -2.81, -1.37, p < 0.00001), glucose (MD: -12.89, 95 % CI: -16.52, -9.26, p < 0.00001), and insulin resistance (MD: -0.89, 95 % CI: -1.15, -0.62, p < 0.00001). Subgroup analysis revealed that irisin raised significantly when resistance training (p = 0.04) and combined training (p = 0.002) were applied, and for the type 2 diabetes and prediabetes (p = 0.002 for both) groups. Moreover, subgroup analysis by the type of intervention demonstrated that insulin reduced when aerobic training (p < 0.00001) and combined training (p = 0.0003) were employed, but glucose and HOMA-IR reduced after all three types of exercise training. These findings demonstrate that exercise interventions may produce ameliorations in circulating irisin. Further long-term studies are required to confirm these findings.

description: Der vorliegende Beitrag geht der Frage nach, welche ethischen Werte ökologisch erzeugter Lebensmittel, die über die Anforderungen der EU-Verordnung zum ökologischen Landbau hinausgehen, für die Kaufentscheidung von Verbrauchern von Interesse sind. Mit Hilfe eines Beobachtungsverfahrens, der Informations- Display-Matrix (IDM), und einer begleitenden Verbraucherbefragung wurde in fünf europäischen Ländern das Informationssuchverhalten von Verbrauchern bezüglich zusätzlicher ethischer Werte ökologischer Lebensmittel untersucht. Unter sieben getesteten ethischen Wertkategorien stellten ‚Artgerechte Tierhaltung’, ‚Regionale Erzeugung’ und ‚Faire Preise für Landwirte’ die wichtigsten Kriterien dar. Ein weiteres Ergebnis ist, dass Verbraucher eine erhöhte Zahlungsbereitschaft für zusätzliche ethische Werte haben. Erzeuger von Öko-Lebensmitteln sind folglich gut beraten, die Einhaltung höherer Standards in Bezug auf die artgerechte Tierhaltung, regionale Erzeugung und faire Erzeugerpreise deutlich stärker als bisher umzusetzen und in den Mittelpunkt ihrer Kommunikation zu stellen. Aus methodischer Sicht hat sich die IDM als Instrument zur Reduzierung des Problems der sozialen Erwünschtheit der Antworten als gut geeignet erwiesen. This contribution determines the relevance of ethical attributes of organic food exceeding the EU regulation on organic farming for consumers’ purchase decisions. The information acquisition behaviour of consumers regarding additional ethical values of organic food was analysed by means of an Information-Display- Matrix (IDM)and an accompanying consumer survey in five European countries. Seven ethical attributes were tested of which ‘animal welfare’, ‘regional production’ and ‘fair prices for farmers’ were identified to be most important. Consumers showed an increased willingness to pay for organic food with these additional ethical attributes. Thus, producers of organic food should increasingly focus on additional ethical attributes such as ‘animal welfare’, ‘local production’ and ‘fair prices for farmers’ in production and communication with consumers. With respect to the methodology used, the IDM turned out to be helpful in reducing the problem of social desirability of answers.

description: We analyze the results for infinite nuclear and neutron matter using the standard relativistic mean field model and its recent effective field theory motivated generalization. For the first time, we show quantitatively that the inclusion in the effective theory of vector meson self-interactions and scalar-vector cross-interactions explains naturally the recent experimental observations of the softness of the nuclear equation of state, without losing the advantages of the standard relativistic model for finite nuclei.

description: Die Fleischwirtschaft steht zunehmend im Fokus der öffentlichen Diskussion. Die Unternehmen der Branche verhalten sich dabei eher passiv. Die Distanz zwischen Gesellschaft und der Fleischwirtschaft ist in den vergangenen Jahren daher größer geworden. Anzeichen für die mangelnde Akzeptanz sind z. B. Initiativen gegen Bauvorhaben, ein geringes Vertrauen und ein steigender Vegetarieranteil. Um Rückschlüsse auf das gesamte Ausmaß dieser Problematik zu gewinnen, wird in der vorliegenden Arbeit die Reputation der Fleischwirtschaft umfassend untersucht. Unter Verwendung der Partial Least Squares Methode (PLS) werden Einfluss- und Erklärungsgrößen analysiert. Die Ergebnisse zeigen, dass das Interesse an und das Wissen über die Branche insgesamt eher gering sind. Hierin begründet sich möglicherweise der hohe Einfluss der affektiven Dimensionen Zuverlässigkeit und Emotional Appeal, während die Erwartungen an die Erfüllung spezifischer Leistungskomponenten (wie z. B. Tierschutz) von untergeordneter Relevanz sind. Die Analysen verdeutlichen die große Bedeutung der Reputation zur Erklärung verschiedener Akzeptanzprobleme der Branche. The German meat industry is increasingly subject to subject to controversy in public debate. The companies within the sector continue to be rather passive regarding this issue. As a consequence, the differences in opinion between society and meat industry have widened in recent years. Indications of a lack of acceptance are, for instance, public campaigns against agricultural building projects, reduced trust in the industry and increasing popularity of vegetarians in the population. In order to investigate the extent of these difficulties, this study analyses the reputation of the meat sector, using the Partial Least Squares Method (PLS). The results indicate that interest in and knowledge about the sector are generally rather poor.

description: Recent anomalies exhibited by satellites and rocket bodies have highlighted that a population of faint debris exists at geosynchronous (GEO) altitudes, where there are no natural removal mechanisms. Despite previous optical surveys probing to around 10-20 cm in size, regular monitoring of faint sources at GEO is challenging, thus our knowledge remains sparse. It is essential that we continue to explore the faint debris population using large telescopes to better understand the risk posed to active GEO satellites. To this end, we present photometric results from a survey of the GEO region carried out with the 2.54 m Isaac Newton Telescope in La Palma, Canary Islands. We probe to 21st visual magnitude (around 10 cm, assuming Lambertian spheres with an albedo of 0.1), uncovering 129 orbital tracks with GEO-like motion across the eight nights of dark-grey time comprising the survey. The faint end of our brightness distribution continues to rise until the sensitivity limit of the sensor is reached, suggesting that the modal brightness could be even fainter. We uncover a number of faint, uncatalogued objects that show photometric signatures of rapid tumbling, many of which straddle the limiting magnitude of our survey over the course of a single exposure, posing a complex issue when estimating object size. This work presents the first instalment of DebrisWatch, an ongoing collaboration between the University of Warwick and the Defence Science and Technology Laboratory (UK) investigating the faint population of GEO debris.

description: In this report, we present the measurements of open charm production at mid-rapidity in p+p, d+Au, and Au+Au collisions at RHIC energies. The techniques of direct reconstruction of open charm via its hadronic decay and indirect measurements through its semileptonic decay are discussed. The beam energy dependence of total charm cross section, electron \pt spectra, and their comparisons to theoretical calculations, including NLO pQCD, are presented. The electron spectra in p+p, d+Au, and Au+Au collisions at \srt=200 GeV show significant variation. The open charm absolute cross section at midrapidity and its centrality dependence are compared to those of inclusive hadrons integrated over $p_{T}>1.5$ GeV/c.
