description: In the field of elastohydrodynamic lubrication (EHL), the influence of temperature differences between components has often been disregarded in calculations and simulations. Therefore, this study focuses on examining the effects of solid body temperatures on two-dimensional line contacts (2D-TEHL), specifically with respect to film thickness and the coefficient of friction (CoF), the two pivotal parameters in lubricating bearing systems. A significant finding of this research is the substantial influence of elevated raceway temperatures on both film thickness and CoF, which arises from the heat transfer process between a heated surface and the lubricating oil. In comparison to the effect of inlet shear heating, this heat transfer induces a more pronounced temperature elevation within the contact region of the oil. Consequently, the study emphasizes the importance of incorporating temperature gradients into the analytical framework used for bearing contact assessments. This inclusion is found to be critical for enhancing the accuracy of predictions regarding film thickness and CoF in lubricated systems.Furthermore, the findings of this research show that applying oil/raceway cooling or heating can be influential in controlling friction or film thickness in bearing systems. This temperature management approach presents promising avenues for optimizing the performance of lubricated bearing systems, offering a significant stride towards enhanced efficiency and longevity. This emphasizes the importance of considering temperature changes in EHL analyses and shows how adjusting temperatures can enhance bearing system performance.

description: Electrically conductive, polymeric materials that maintain their conductivity even when under significant mechanical deformation are needed for actuator electrodes, conformable electromagnetic shielding, stretchable tactile sensors and flexible energy storage. The challenge for these materials is that the percolated, electrically conductive networks tend to separate even at low strains, leading to significant piezoresistance. Herein, deformable conductors were fabricated by spray-coating a nitrile substrate with a graphene-elastomer solution. The coatings showed only slight increase in electrical resistance after thousands of bending cycles and repeated folding-unfolding events. The deformable conductors doubled their electrical resistance at 12% strain and were washable without changing their electrical properties. The conductivity-strain behaviour was modelled by considering the nanofiller separation upon deformation. To boost the conductivity at higher strains, the production process was adapted by stretching the nitrile substrate before spraying, after which it was released. This adaption meant that the electrical resistance doubled at 25 % strain. The electrical resistance was found sufficiently low to give a 1.9 dB/μm shielding in the 8-12 GHz electromagnetic band. The physical and electrical properties, including the EM screening, of the flexible conductors, were found to deteriorate upon cycling but could be recovered through reheating the coating.

description: As a coastal district located in the Southeast of Ho Chi Minh City (HCMC), Vietnam, Can Gio is characterized by low average terrains ranging up to only 1.5m above the sea level. Impacted by climate change and sea level rise in recent years, certain neighborhoods in the Can Gio District have been facing the loss of their residential and arable lands, as well as undesired relocations. Together with riverbank and coastal erosion, this phenomenon has several negative impacts on the lives of people in residential areas and on their economic activities. This research uses a literature review and observation as the main methods to explore the experiences of sea level rise adaptive housing and thereby suggests certain solutions for the Can Gio District. The solutions include saving space for water, elevating floors, constructing with floating floors, and creating biological ditches and osmotic lines to help quickly drain flooded water. These solutions aim to protect people’s lives and houses against the rising sea level and ensure the sustainable development of the neighborhoods.

Leur réussite en grande distribution incite les enseignes à les utiliser sur leurs propres marques. Les filières concernées craignent que produire sous marques de distributeur ne s'accompagne d'une dévalorisation de l'image de ces signes. Ce document montre, en s'appuyant sur l'analyse de six produits, que la stratégie de la grande distribution n'est pas de brader les signes officiels de qualité.

Numerical simulations of expanding supershells in dwarf irregular galaxies. II. Formation of giant HI rings

Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)

description: We perform numerical hydrodynamic modeling of various physical processes that can form an HI ring as is observed in Holmberg I. Three energetic mechanisms are considered: multiple supernova explosions (SNe), a hypernova explosion associated with a gamma ray burst (GRB), and the vertical impact of a high velocity cloud (HVC). The total released energy has an upper limit of 10^54 ergs. We find that multiple SNe are in general more effective in producing shells that break out of the disk than a hypernova explosion of the same total energy. As a consequence, multiple SNe form rings with a high ring-to-center contrast K<100 in the HI column density, whereas single hypernova explosions form rings with K<10. Only multiple SNe can reproduce both the size (diameter \~1.7 kpc) and the ring-to-center contrast (K ~ 15-20) of the HI ring in Hoolmberg I. High velocity clouds create HI rings that are much smaller in size (< 0.8 kpc) and contrast (K < 4.5) than seen in Holmberg I. We construct model position-velocity (pV) diagrams and find that they can be used to distinguish among different HI ring formation mechanisms. The observed pV-diagrams of Holmberg I are best reproduced by multiple SNe. We conclude that the giant HI ring in Holmberg I is most probably formed by multiple SNe. We also find that the appearance of the SNe-driven shell in the integrated HI image depends on the inclination angle of the galaxy. In nearly face-on galaxies, the integrated HI image shows a ring of roughly constant HI column density surrounding a deep central depression, whereas in considerably inclined galaxies (i > 45 deg) the HI image is characterized by two kidney-shaped density enhancements and a mild central depression.

description: We analyze the indirect detection of neutralino dark matter in supergravity scenarios with non-universal soft scalar and gaugino masses. In particular, the gamma-ray flux arising from the galactic center due to neutralino annihilation is computed. In important regions of the parameter space it can be increased significantly (about two orders of magnitude) with respect to the universal scenario. This result is compared with the sensitivity of current and planned experiments, such as the satellite-based detectors EGRET and GLAST and the ground-based atmospheric telescope HESS. For example, for $\tanβ< 35$ the sensitivity region of GLAST and HESS can only be reached in non-universal scenarios.

description: The results of different non-perturbative studies agree on a power law as the infrared behavior of the Landau gauge gluon propagator. This propagator violates positivity and thus indicates the absence of the transverse gluons from the physical spectrum, i.e. gluon confinement. A simple analytic structure for the gluon propagator is proposed capturing all of its features. We comment also on related investigations for the Landau gauge quark propagator.

description: Depuis 30 ans, la corpulence (encadré 1) a connu un développement différent en France et aux Etats-Unis. L’obésité n'y est aujourd'hui comparable ni par son ampleur, ni par sa répartition par âge et par sexe, même si la situation française montre une croissance plus rapide du phénomène ces dernières années. De part et d'autre de l'Atlantique, l'obésité est liée à la hiérarchie sociale, en particulier chez les femmes et si elle a augmenté dans tous les milieux sociaux entre 1970 et 2000, on ne constate pas de véritable affaiblissement du rôle de ces facteurs sociaux dans l'obésité. L'étude de l'attention portée au poids, inégale selon les catégories sociales, montre que les individus les plus touchés par l'obésité appartiennent aux groupes sociaux où la corpulence moyenne est la plus élevée et où l'attention portée au poids est la moins forte. Une politique préventive de santé publique ne devrait-elle pas dès lors porter sur l'ensemble de ces catégories modestes ?

description: D'une situation de faible importance dans la sole agricole française (324 000 hectares en 2004 dont 300 000 hectares de colza), les cultures énergétiques devraient connaître un rapide accroissement de leur surface afin de permettre d'atteindre un niveau d'incorporation de 5,75% de biocarburants dans les carburants fossiles à l'horizon 2010 (valeur recommandée par la Directive 2003/30/CE, dite "promotion des biocarburants"). Le gouvernement français a d'ailleurs récemment augmenté les autorisations de production. Dans le contexte actuel où le prix du pétrole côtoie les 70$ par baril et où la lutte contre le réchauffement climatique devient une priorité, les biocarburants sont présentés sous un angle très favorable. Cependant, compte tenu de leur rendement énergétique par hectare de terre dans l'ensemble très moyen et de leurs coûts élevés, on est amené à tempérer les analyses très optimistes qui les entourent. Présentés essentiellement comme des filières énergétiques, on oublie de souligner que les biocarburants sont également un moyen indirect de soutien de l'agro-industrie et de l'agriculture, sous la responsabilité de chaque pays. Les principaux résultats résumés ici concernent la France. Ils sont obtenus en utilisant un modèle d'équilibre partiel et dynamique, OSCAR, mis au point par l'INRA (encadré 1). Les points forts de ce modèle consistent en une formalisation détaillée des offres agricoles, alimentaire et non alimentaire, compte tenu des évolutions de la PAC et des impacts des biocarburants sur les revenus ainsi que sur les emplois agricoles.

description: We have investigated the rheology and structure of a gel formed from a mixture of non-Brownian particles and two immiscible liquids. The suspension of particles in a liquid undergoes gelation upon the addition of a small content of second, wetting liquid which forms liquid bridges between particles leading to a sample spanning network. The rheology of this gel primarily exhibits a yield stress at low shear rates followed by a linear variation of shear stress at high shear rates. The apparent yield stress extracted from the flow curves increases rapidly with volume fraction of second liquid before saturation, while it exhibits a monotonic increase with increasing particle concentration. Rescaling of the yield stress curves using suitable shift factors results in an empirical expression for the yield stress showing squared dependence on liquid fraction and a rapid increase with particle fraction above a certain value, both combined in a highly nonlinear manner. The microstructural variations with changing secondary liquid content and particle fractions are captured using three dimensional X-ray tomography technique. The microstructure is observed to show increased local compactness with increased liquid content and increased spatial homogeneity with increased particle fractions. The images from X-ray tomography are analysed to obtain the distributions of particle-particle bonds (coordination number) in the system which serve to explain the observed yield stress behavior in a qualitative manner.

description: The gasification of lignite could be a promising sustainable alternative to combustion, because it causes reduced emissions and allows the production of syngas, which is a versatile gaseous fuel that can be used for cogeneration, Fischer-Tropsch synthesis, or the synthesis of other bio-fuels, such as methanol. For the safe and smooth exploitation of syngas, it is fundamental to have a high quality gas, with a high content of H₂ and CO and minimum content of pollutants, such as particulate and tars. In this work, experimental tests on lignite gasification are carried out in a bench-scale fluidized-bed reactor with olivine as bed material, chosen for its catalytic properties that can enhance tar reduction. Some operating parameters were changed throughout the tests, in order to study their influence on the quality of the syngas produced, and pressure fluctuation signals were acquired to evaluate the fluidization quality and diagnose correlated sintering or the agglomeration of bed particles. The effect of temperature and small air injections in the freeboard were investigated and evaluated in terms of the conversion efficiencies, gas composition, and tar produced.

Estimating metabolic rate in tegu lizards (Tupinambis merianae) : can one calculate oxygen consumption from heart rate?
Creators: name: Piercy, Joanna Carolyne
Publisher: name: University of British Columbia
Year: 2009

description: There are a number of methods commonly used to estimate metabolic rate in animals, one of which is the Heart Rate Method. Heart rate (f[sub H]) can theoretically be used as a direct proxy for O₂ consumption (V[sub O]) according to Fick's equation (V[sub O] = f[sub H] x O₂ pulse) as long as the O₂ pulse varies in a predictable manner. The benefit of this method is that heart rate is easily monitored both in the lab and in the field, is sensitive to short-term changes in activity, and can be monitored continuously on the order of weeks or months. Studies have confirmed that in some birds, mammals, and at least one species of reptile, the accuracy of this method is at least as great as that of the doubly-labelled water method. My goal was to determine if heart rate can be used as a reliable estimate of metabolic rate in tegu lizards. To this end, f[sub H] and V[sub O] were measured simultaneously in fasting lizards at 17°C, 27°C and 37°C, and in digesting lizards at 37°C. Regression analysis showed that, at any given temperature or digestive state, the relationship between f[sub H] and V[sub O] was highly variable between individuals (as indicated by different slopes and intercepts) as well as within individuals (as indicated by low r² values). Regression analysis on data pooled within each treatment failed to account for this variability. However, regression analysis of the dataset in its entirety accounted for 740/0 of the variability. The equation which best described the relationship in unstressed animals was lnsV[sub O] = —3.441 + 0.679 InF[sub R]. Predictions of total metabolic rate calculated from this general calibration equation were typically more accurate than predictions based on the Time Energy Budget method.

description: Ultrafast measurement technology provides essential contributions to our microscopic understanding of the properties and functions of solids and nanostructures. Atomic-scale vistas with ever-growing spatial and temporal resolution are offered by methods based on short pulses of x-rays and electrons. Time-resolved electron diffraction and microscopy are among the most powerful approaches to investigate non-equilibrium structural dynamics in excited matter. In this article, we discuss recent advances in ultrafast electron imaging enabled by significant improvements in the coherence of pulsed electron beams. Specifically, we review the development and first application of Ultrafast Low-Energy Electron Diffraction (ULEED) for the study of structural dynamics at surfaces, and discuss novel opportunities of Ultrafast Transmission Electron Microscopy (UTEM) facilitated by laser-triggered field emission sources. These and further developments will render coherent electron beams an essential component in the future of ultrafast nanoscale imaging.

Dabei finden unterschiedliche methodische Ansätze Anwendung (Marktanteilsanalyse, Standortanalyse, Produktionskostenanalyse), deren Ergebnisse zu einem Gesamtbild zusammengefügt werden. Es zeigt sich, dass eine eindeutige Gesamtaussage zur künftigen Entwicklung der Milchproduktion auf Grund sich teilweise widersprechender Ergebnisse nicht erfolgen kann. Dennoch stellen die gewonnenen Erkenntnisse eine wichtige Orientierungshilfe dar. Results of analysis of agricultural statistics offer estimations about the future regional relocation of dairy production in Germany. Different methodologies are used within this paper to have a full overview on the most important aspects (analysis of market shares, site factor analysis, analysis of production costs). Analysis show partly conflicting results which do not allow exact predictions on future relocations of dairy production. But the results still give important guidelines on future changes.

At $z=0$, 8.9\% of 1232 disc galaxies with stellar mass $>10^{10.5}M_{\odot}$ in Illustris-1 are barred, while the numbers are 55\% of 1269 in TNG100. The bar fraction as a function of stellar mass in TNG100 agrees well with the survey $S^4G$. The median redshift of bar formation are $\sim 0.4-0.5$ and $\sim 0.25$ in TNG100 and Illustris-1 respectively. Bar fraction generally increases with stellar mass and decreases with gas fraction in both simulations. Barred galaxy had higher gas fraction at high redshift tend to form bar later. When the bars were formed, the disc gas fractions were mostly lower than 0.4. The much higher bar fraction in TNG100 probably have benefit from much lower gas fraction in massive disc galaxies since $z\sim3$, which may result from the combination of more effective stellar and AGN feedback. The latter may be the primary factor at $z<2$. Meanwhile, in both simulations, barred galaxies have higher star formation rate before bar formation, and stronger AGN feedback all the time than unbarred galaxies. The properties of dark matter halos hosting massive disc galaxies are similar between two simulations, and should have minor effect on the different bar frequency. For individual galaxies under similar halo environment cross two simulations, different baryonic physics can lead to striking discrepancy on morphology. The morphology of individual galaxies is subject to combined effects of environment and internal baryonic physics, and is often not predictable.

On X-ray-singularities in the f-electron spectral function of the Falicov-Kimball model

description: The f-electron spectral function of the Falicov-Kimball model is calculated within the dynamical mean-field theory using the numerical renormalization group method as the impurity solver. Both the Bethe lattice and the hypercubic lattice are considered at half filling. For small U we obtain a single-peaked f-electron spectral function, which --for zero temperature-- exhibits an algebraic (X-ray) singularity ($|ω|^{-α}$) for $ω\to 0$. The characteristic exponent $α$ depends on the Coulomb (Hubbard) correlation U. This X-ray singularity cannot be observed when using alternative (Keldysh-based) many-body approaches. With increasing U, $α$ decreases and vanishes for sufficiently large U when the f-electron spectral function develops a gap and a two-peak structure (metal-insulator transition).

description: At the core of many EU Commission and member states’ recent discussions of China is the concept of “de-risking.” Distinct from “decoupling,” the concept focuses on mitigating risks and limiting strategic dependencies in Europe’s relationship with China. They would achieve this using the EU’s economic defenses more effectively and engaging in open and frank dialogue, while remaining open to targeted cooperation and economic ties that are considered “un-risky.”

Discrepancies between the Commission and member states underscore the ongoing debate about what it means to “de-risk.” Even as many EU member states broadly agree on the challenges posed by contemporary EU-China relations, their post-pandemic approaches to re-engaging with Beijing have taken very different forms. What is the state of the de-risking China debate following the release of Germany’s China Strategy, and what will de-risking ultimately mean in practice?

In this round of MERICS’ EU-China opinion pool, MERICS Analyst Grzegorz Stec asked several experts:

description: We use the light-front machinery to study the behavior of a relativistic free particle and obtain the quantum commutation relations from the classical Poisson brackets. We argue that the usual projection onto the light-front coordinates for these from the covariant commutation ralations does not reproduce the expected results.

Non-linear deformation and break up of enclaves in a rhyolitic magma: a case study from Lipari Island (Southern Italy)

description: A dome from Lipari Island (Southern Italy) consists of 12 vol. percent of circular, elongated and folded latitic enclaves hosted in a rhyolitic matrix. The dm- to cm-scale enclaves are more deformed than the mm-scale blobs. The critical value of the ratio between the viscous forces, which allow deformation and eventually break up blobs of latitic magma, and the interfacial tension forces is larger than 0.29. The Reynolds number is < 5.3. The equivalent radius and the axial ratio of the enclaves follow power-law distributions. This feature suggests that the break up and stretching of magmas are non-linear, scale-invariant, probably cyclic processes. The coexistence of enclaves of different shape and the self-similar size distributions suggest that chaotic advection plays a major role in the formation of mingled magmas. Caution must be used when measuring the finite strain from enclave shapes because they may break apart during the deformation.

Friction Force in Strongly Magnetized Plasmas

description: A charged particle moving through a plasma experiences a friction force that commonly acts antiparallel to its velocity. It was recently predicted that in strongly magnetized plasmas, in which the plasma particle gyro-frequency exceeds the plasma frequency, the friction also includes a transverse component that is perpendicular to both the velocity and Lorentz force. Here, this prediction is confirmed using molecular dynamics simulations, and it is shown that the relative magnitude of the transverse component increases with plasma coupling strength. This result influences single particle motion and macroscopic transport in strongly magnetized plasmas found in a broad range of applications.

description: Das Auslaufen der EU-Milchgarantiemengenregelung (im Folgenden: Milchquotenregelung) im Jahr 2015 erfordert von den Milcherzeugern Anpassungsmaßnahmen. Vermutlich werden diese Anpassungsmaßnahmen zu strukturellen Veränderungen sowohl auf regionaler als auch auf betrieblicher Ebene führen. Im Rahmen der hier dargestellten Studie wurden 411 Milcherzeuger in Baden-Württemberg befragt (versandte Fragebögen 1 050, Rücklaufquote 39 %), wie sie auf das mögliche Auslaufen der Milchquotenregelung reagieren werden. Die Prognose der Veränderungen auf regionaler Ebene zeigt, dass auch in einem baden-württembergischen Gunststandort der Milcherzeugung die Produktion eingeschränkt werden könnte. Im Rahmen von Diskriminanzanalysen werden die Milcherzeuger, die den Ausstieg aus der Milchviehhaltung planen, denen gegenübergestellt, welche eine Ausdehnung der Milcherzeugung beabsichtigen. Es kann gezeigt werden, dass in den verschiedenen Regionen nicht allein die Betriebsgröße der Faktor ist, welcher die beiden Gruppen unterscheidet, sondern auch die Erwerbsform und die Grundhaltung der Betriebsleiter. The abolition of the EU Milk Quota Regulation in 2015 will require milk producers to adapt. Their having to adapt is likely lead to structural changes both at regional level and at farm level. 411 milk producers in Baden- Wuerttemberg were surveyed in the course of the study (1 050 questionnaires, feedback 39 %). The main objective was to examine their likely reactions to the abolition of the milk quota regulation. The forecast shows that even in a favoured region for milk production, the overall output of milk could be reduced. Two groups of milk producers are compared by discriminant analysis. The farmers of the first group plan to quit milk production whereas the farmers of the second group intend to increase the output of milk. There is evidence that farm size alone is not the only discriminating factor in different regions, but that organisation on a sideline basis and the attitude of the farm operators also play a role.

Self-regulation and choice : the depleting effects of choosing for self versus other
Creators: name: Rawn, Catherine Dianne
Publisher: name: University of British Columbia
Year: 2009

description: Choosing for the self depletes self-regulatory resources, impairing the ability to exert self-control subsequently (Vohs, Baumeister, Twenge et al., 2005). The current study examined the effect of choosing for others. Because people with interdependent self-construals privilege interpersonal relationships, Asian-Canadians, but not European-Canadians, were expected to experience greater depletion after choosing for others than after choosing for the self, relative to not making choices. Participants made paint color choices from over 200 options while imagining redecorating a room for self or other. Control condition participants simply perused the same options. Persistence on a subsequent math task indexed depletion. A s predicted, European-Canadians choosing for self persisted less than those in the other two conditions. Unexpectedly, Asian-Canadians' persistence was unaffected by the manipulation.
