title: Utopia jako edukacyjna interwencja. Od dekonstruowania heterotopii w narracjach do multikulturalizmu
Creators: name: Mendel, Maria
Publisher: name: Instytut Pedagogiki Uniwersytetu Wrocławskiego
Year: 2017

description: Utopię jako edukacyjną interwencję omawiam w perspektywie myśli Michela Foucaulta. Posłuży ona jako punkt wyjścia oraz element organizujący analizę materiału narracyjnego (wypowiedzi biograficznych pochodzących z moich dawniej zrealizowanych badań). W analizie tej centrum zainteresowania stanowi zmiana podmiotowego statusu narratora. Zmiana ta może być interpretowana jako edukacyjna interwencja dokonująca się za pośrednictwem utopii. Stąd bierze początek koncepcja edukacyjna tworzona wokół rozwiązania teoretycznego, jednego z wielu, które uwidaczniają się w pejzażu, jaki roztacza refleksja o utopii rozwijana w ramach myśli pedagogicznej.

description: We present a technique for measuring the transverse spatial properties of an optical wavefront. Intensity and phase profiles are recovered by analysis of a series of interference patterns produced by the combination of a scanning X-shaped slit and a static horizontal slit; the spatial coherence may be found from the same data. We demonstrate the technique by characterizing high harmonic radiation generated in a gas cell, however the method could be extended to a wide variety of light sources.

title: The Effect of Various Doses of Caffeine Upon the Maximal Muscular Endurance of College Females

description: A limited number of investigations dealing with the effects of caffeine upon human physical performance have been conducted. Since caffeine is a central nervous system stimulant and it is a constituent of the popularly-consumed beverages - coffee, tea, and cola drinks, it would appear that numerous studies would have been conducted in order to determine the effect of caffeine upon human muscular performance. At any rate, there is a dearth of studies on this topic and the findings of the conducted experiments are equivocal and ambiguous.

The purpose of the present study was to determine the effects of various doses of caffeine upon the following parameters: resting heart rate, submaximal exercise heart rate at the workloads of 300, 400, and 500 kpm, maximal exercise heart rate, maximal muscular endurance time, subjective ratings of perceived exertion at the workloads of 300, 400, and 500 kpm, and the maximal subjective rating of perceived exertion.

Subjects in this study consisted of a group of fourteen college females. All of the testing was performed in the Human Performance Laboratory at Old Dominion University in Norfolk, Virginia. Each subject was involved in six testing periods which included two practice trials and four testing periods. Specific doses of either 0 mg of citrated caffeine per kg of body weight, 4 mg/kg, 7 mg/kg, and 10 mg/kg were administered to the subjects at each testing period. The performance test was a ride to exhaustion on the bicycle ergometer while the heart rate was monitored continuously.

This study was of a repeated measures design where all of the treatments were counterbalanced. The 0 mg/kg dose of citrated caffeine was considered to be the placebo treatment. The order of treatments was unknown to the subjects and the investigator, thus making this a double blind study.

Within the limitations of this study, it was found that there were no statistically significant effects of various doses of caffeine upon the tested parameters .

description: We use spin-density-functional theory (SDFT) ab initio calculations to theoretically explore the possibility of achieving useful gate control over exchange coupling between cobalt clusters placed on a graphene sheet. By applying an electric field across supercells we demonstrate that the exchange interaction is strongly dependent on gate voltage, but find that it is also sensitive to the relative sublattice registration of the cobalt clusters. We use our results to discuss strategies for achieving strong and reproducible magneto-electric effects in graphene/transition-metal hybrid systems.

Spin force and the generation of sustained spin current in time-dependent Rashba and Dresselhauss systems

description: The generation of spin current and spin polarization in a 2DEG structure is studied in the presence of Dresselhaus and Rashba spin-orbit couplings (SOC), the strength of the latter being modulated in time by an ac gate voltage. By means of the non-Abelian gauge field approach, we established the relation between the Lorentz spin force and the spin current in the SOC system, and showed that the longitudinal component of the spin force induces a transverse spin current. For a constant (time-invariant) Rashba system, we recover the universal spin Hall conductivity of $\frac e{8π}$, derived previously via the Berry phase and semiclassical methods. In the case of a time-dependent SOC system, the spin current is sustained even under strong impurity scattering. We evaluated the ac spin current generated by a time-modulated Rashba SOC in the absence of any dc electric field. The magnitude of the spin current reaches a maximum when the modulation frequency matches the Larmor frequency of the electrons.

description: The Timepix particle tracking telescope has been developed as part of the LHCb VELO Upgrade project, supported by the Medipix Collaboration and the AIDA framework. It is a primary piece of infrastructure for the VELO Upgrade project and is being used for the development of new sensors and front end technologies for several upcoming LHC trackers and vertexing systems. The telescope is designed around the dual capability of the Timepix ASICs to provide information about either the deposited charge or the timing information from tracks traversing the 14 x 14mm matrix of 55 x 55 um pixels. The rate of reconstructed tracks available is optimised by taking advantage of the shutter driven readout architecture of the Timepix chip, operated with existing readout systems. Results of tests conducted in the SPS North Area beam facility at CERN show that the telescope typically provides reconstructed track rates during the beam spills of between 3.5 and 7.5 kHz, depending on beam conditions. The tracks are time stamped with 1 ns resolution with an efficiency of above 98% and provide a pointing resolution at the centre of the telescope of 1.6 um . By dropping the time stamping requirement the rate can be increased to 15 kHz, at the expense of a small increase in background. The telescope infrastructure provides CO2 cooling and a flexible mechanical interface to the device under test, and has been used for a wide range of measurements during the 2011-2012 data taking campaigns.

description: We have compared the observed distribution of galaxies in the plane of specific star formation rate versus stellar mass with the predictions of the Garching semi-analytic model at redshifts 0, 1 and 2. The goal is to test whether the implementation of radio mode AGN feedback, which is responsible for terminating the formation of stars in high mass galaxies, provides an adequate match to current high-redshift observations. The fraction of quenched galaxies as a function of stellar mass in the models is in good agreement with data at z=0 and z=1. By z=2, there are too few quenched galaxies with low stellar masses in the models. At z=2, the population of galaxies with no ongoing star formation is clearly separated from the `main sequence' of star-forming galaxies in the data. This is not found in the models, because z=2 galaxies with stellar masses less than 10^11 solar masses are predicted to host black holes with relatively low masses (less than 10^8 solar masses). The current implementation of radio mode feedback from such black holes reduces the cooling rates from the surrounding halo, but does not generate sufficient energy to stop star formation entirely. We suggest that the models may be brought into better agreement with the data if black hole growth is triggered by disc instabilities in addition to major mergers, and if feedback mechanisms associated with the formation of galactic bulges act to quench star formation in galaxies.

description: Most of the well-preserved ophiolite complexes are believed to form in suprasubduction zone (SSZ) settings. We compare physical properties and seismic structure of SSZ crust at the Izu-Bonin-Mariana (IBM) fore arc with oceanic crust drilled at Holes 504B and 1256D to evaluate the similarities of SSZ and oceanic crust. Expedition 352 basement consists of fore-arc basalt (FAB) and boninite lavas and dikes. P-wave sonic log velocities are substantially lower for the IBM fore arc (mean values 3.1–3.4 km/s) compared to Holes 504B and 1256D (mean values 5.0–5.2 km/s) at depths of 0–300 m below the sediment-basement interface. For similar porosities, lower P-wave sonic log velocities are observed at the IBM fore arc than at Holes 504B and 1256D. We use a theoretical asperity compression model to calculate the fractional area of asperity contact Af across cracks. Af values are 0.021–0.025 at the IBM fore arc and 0.074–0.080 at Holes 504B and 1256D for similar depth intervals (0–300 m within basement). The Af values indicate more open (but not necessarily wider) cracks in the IBM fore arc than for the oceanic crust at Holes 504B and 1256D, which is consistent with observations of fracturing and alteration at the Expedition 352 sites. Seismic refraction data constrain a crustal thickness of 10–15 km along the IBM fore arc. Implications and inferences are that crust-composing ophiolites formed at SSZ settings could be thick and modified after accretion, and these processes should be considered when using ophiolites as an analog for oceanic crust.

description: We report the results of a high-statistics search for H-dibaryon production in inclusive Y(1S) and Y(2S) decays. No indication of an H-dibaryon with mass near the M_H=2m_Lambda threshold is seen in either the H-> Lambda p pi- or Lambda-Lambda decay channels and 90% confidence level branching-fraction upper limits are set that are between one and two orders of magnitude below the measured branching fractions for inclusive Y(1S) and Y(2S) decays to antideuterons. Since Y(1,2S) decays produce flavor-SU(3)-symmetric final states, these results put stringent constraints on H-dibaryon properties. The results are based on analyses of 102 million Y(1S) and 158 million Y(2S) events collected with the Belle detector at the KEKB electron-positron collider.

description: The African coffee white stem borer (CWSB) Monochamus leuconotus is a destructive pest of Arabica coffee in Africa. Documentation on outbreaks, spatiotemporal development and the relationship with different environmental conditions and coffee production system is limited. To underpin effective control measures, we studied aspects of local and regional pest drivers in Eastern Uganda. At the local scale, we (i) characterized the temporal development of CWSB and explored associations with environmental and shade-related indicators. During two growing seasons and on 84 coffee plots, we recorded CWSB incidence/infestation and microclimate on an altitudinal gradient and different shading systems. The bimodal rainfall, altitude and shade affected CWSB development through their effect on minimum temperature. At the landscape level, we (ii) analyzed the spatial pattern of CWSB. Data on CWSB were collected on 180 plots. Pest incidence showed a spatial arrangement varying by districts. A possible relationship with human movement and the landscape context contributing to pest spread is suggested. CWSB control measures should be synchronized with the bimodal rainfall patterns and an emphasis should be given to identifying and limiting pathways of pest spread from highly infested to new areas.

Subjects: subject: Mathematical Physics (math-ph)

description: Combinatorial expressions are presented to the solutions to initial value problems of the discrete and ultradiscrete Toda molecules. For the discrete Toda molecule, a subtraction-free expression of the solution is derived in terms of non-intersecting paths, for which two results in combinatorics, Flajolet's interpretation of continued fractions and Gessel--Viennot's lemma on determinants, are applied. By ultradiscretizing the subtraction-free expression, the solution to the ultradiscrete Toda molecule is obtained. It is finally shown that the initial value problem of the ultradiscrete Toda molecule is exactly solved in terms of shortest paths on a specific graph.

Accurate Distance and Battery Capacity Estimation for Battery-Powered Electric Locomotives

Publisher: name: Macquarie University
Year: 2025
Subjects: classificationCode: 350907
subject: Rail transportation and freight services

description: This thesis focuses on investigating the impact that on-board energy storage devices have on battery powered electric railways as an alternative to conventional railway electrification. For battery locomotives to achieve maximum distances in catenary-free routes, the majority of current research is around the design of the rail vehicle and sizing of batteries. There is a lack of study of the effect of design parameters on the battery locomotive performance for design engineers to consider. Currently, the maximum distance known for the battery to provide before the need for re-charging is known for straight tracks. Most of the time, railway corridors do not face ideal conditions and designers must deal with the challenges of varying rail routes such as those containing curved and elevated tracks, tunnels and bridges which limit speeds and multiple stations. Knowing the estimated distance the battery can provide for any railway infrastructure condition will allow designers and operators to optimise their design and allocate conventional routes in geographical areas only where required. Further where the given distance is not enough, knowing the battery capacity required to achieve the distance for a given railway route with any varying external rail condition through this mode will be helpful. In this research, an energy balance approach has been proposed to determine the battery sizing and maximum distance travelled by battery driven electric vehicles (commonly lithium-ion battery driven) during catenary-free operation for any railway environment. Using the developed energy balance approach, an algorithm has been developed to determine the maximum distance the battery can deliver, and battery sizing required to travel a desired distance as a function of several variables. This research further presents a mathematical model and dynamic simulation of an electric train from a railway electrification designer's perspective, with real-life issues and design constraints considered and input into the model. MATLAB based simulation model consists of the battery train’s longitudinal dynamics, electric system, and on-board energy storage for any given railway route as a function of time. This allows the study of the internal operations and characteristics of the battery locomotive and the effect of the on-board energy storages on the rail vehicle’s performance. The results have been compared and validated with real life railway routes and data following Australian railway standards to ensure accuracy and validity.

description: We construct six-dimensional superconformal models with non-abelian tensor and hypermultiplets. They describe the field content of (2,0) theories, coupled to (1,0) vector multiplets. The latter are part of the non-abelian gauge structure that also includes non-dynamical three- and four-forms. The hypermultiplets are described by gauged nonlinear sigma models with a hyper-Kaehler cone target space. We also address the question of constraints in these models and show that their resolution requires the inclusion of abelian factors. These provide couplings that were previously considered for anomaly cancellations with abelian tensor multiplets and resulted in the selection of ADE gauge groups.

description: We report a super-linear correlation for the star formation law based on new CO($J$=1-0) data from the CARMA and NOBEYAMA Nearby-galaxies (CANON) CO survey. The sample includes 10 nearby spiral galaxies, in which structures at sub-kpc scales are spatially resolved. Combined with the star formation rate surface density traced by H$α$ and 24 $μ$m images, CO($J$=1-0) data provide a super-linear slope of $N$ = 1.3. The slope becomes even steeper ($N$ = 1.8) when the diffuse stellar and dust background emission is subtracted from the H$α$ and 24 $μ$m images. In contrast to the recent results with CO($J$=2-1) that found a constant star formation efficiency (SFE) in many spiral galaxies, these results suggest that the SFE is not independent of environment, but increases with molecular gas surface density. We suggest that the excitation of CO($J$=2-1) is likely enhanced in the regions with higher star formation and does not linearly trace the molecular gas mass. In addition, the diffuse emission contaminates the SFE measurement most in regions where star formation rate is law. These two effects can flatten the power law correlation and produce the apparent linear slope. The super linear slope from the CO($J$=1-0) analysis indicates that star formation is enhanced by non-linear processes in regions of high gas density, e.g., gravitational collapse and cloud-cloud collisions.

Taylor's swimming sheet: Analysis and improvement of the perturbation series

description: In G.I. Taylor's historic paper on swimming microorganisms, a two dimensional sheet was proposed as a model for flagellated cells passing traveling waves as a means of locomotion. Using a perturbation series, Taylor computed swimming speeds up to fourth order in amplitude. Here we systematize that expansion so that it can be carried out formally to arbitrarily high order. The resultant series diverges for an order one value of the wave amplitude, but may be transformed into series with much improved convergence properties and which yield results comparing favorably to those obtained numerically via a boundary integral method for moderate and large values of the wave amplitudes.

Dynamics of ultra-intense circularly polarized solitons under inhomogeneous plasmas

description: The dynamics of the ultra-intense circularly polarized solitons under inhomogeneous plasmas are examined. The interaction is modeled by the Maxwell and relativistic hydrodynamic equations and is solved with fully implicit energy-conserving numerical scheme. It is shown that a propagating weak soliton can be decreased and reflected by increasing plasma background, which is consistent with the existing studies based on hypothesis of weak density response. However it is found that ultra-intense soliton is well trapped and kept still when encountering increasing background. Probably, this founding can be applied for trapping and amplifying high-intensity laser-fields.

title: Pollinator Visitation Frequency Associated with Native and Non-Native Plants in a Mid-Atlantic Piedmont (USA) Urban Garden
Creators: name: Virginia Academy of Science, Old Dominion University Libraries

description: The recent focus on the importance of native plants and their pollinators has highlighted the critical role of local species in their natural environment. As urban encroachment, climate change, and invasive species continues to threaten native habitats, it is increasingly important to promote the use of local green spaces as refugia for native plants and their pollinators. The aim of this project, therefore, was to identify and assess the visitation frequency of insect pollinators associated with an urban setting within the Piedmont region of Virginia, and compare their association with native versus closely-related but non-native summer-flowering plants. Several modes of insect examination were used to assess these metrics in the Brian Wesley Moores Native Plant Garden on the campus of Randolph-Macon College. We observed an overall preference for the native species on a total of four native:non-native pair comparisons, including a higher number of total insect visitors and a more diverse assortment of pollinator types. Our data supports the notion that native plant species should be prioritized in urban green spaces, as it provides the appropriate flora to support ecosystem balance in a setting threatened by human activities.

description: In this paper we have discussed about the number of automobiles that has been increased on the road in the past few years. Due to high density of vehicles, the potential threats and road accident is increasing. Wireless technology is aiming to equip technology in vehicles to reduce these factors by sending messages to each other. The vehicular safety application should be thoroughly tested before it is deployed in a real world to use. Simulator tool has been preferred over out door experiment because it simple, easy and cheap. VANET requires that a traffic and network simulator should be used together to perform this test. Many tools exist for this purpose but most of them have the problem with the proper interaction. Simulating vehicular networks with external stimulus to analyze its effect on wireless communication but to do this job a good simulator is also needed.

description: We consider pure SU(2) Yang–Mills theory on four-dimensional de Sitter space dS 4 and construct smooth and spatially homogeneous classical Yang–Mills fields. Slicing dS 4 as ℝ×S 3 , via an SU(2)-equivariant ansatz we reduce the Yang–Mills equations to ordinary matrix differential equations and further to Newtonian dynamics in a particular three-dimensional potential. Its classical trajectories yield spatially homogeneous Yang–Mills solutions in a very simple explicit form, depending only on de Sitter time with an exponential decay in the past and future. These configurations have not only finite energy, but their action is also finite and bounded from below. We present explicit coordinate representations of the simplest examples (for the fundamental SU(2) representation). Instantons (Yang–Mills solutions on the Wick-rotated S 4 ) and solutions on AdS 4 are also briefly discussed.

description: Microalgal cultivations present challenges for monitoring and process control posed by their large scale and the likelihood that they will be composed of multiple species. Cell concentration is a fundamental parameter in any cultivation but is typically measured using off-line methods that may be time-consuming, laborious, or subject to interferences. Here, an in-situ microscope has been adapted for monitoring microalgal cultivations by adding a flow-through cell and adjusting image-processing algorithms. After installation in the bypass of a photobioreactor, the microscope enabled the continuous, automated acquisition of cell count, cell size, and cell morphology data on-line during cultivation processes over a period of 20. days, without sampling. The flow-through microscope was tested in cultivations of Chlamydomonas reinhardtii and Chlorella vulgaris. Cell concentration measurements were in agreement with off-line optical density measurements for both species. In addition, cell size and morphology distributions were obtained that revealed population shifts during the cultivation of C. vulgaris. This monitoring system thus provides a means to obtain detailed, non-invasive insights of microalgal cultivation processes.

description: A detailed analysis of second-order moment budgets for cloud topped boundary layers (CTBLs) is performed using high-resolution large-eddy simulation (LES). Two CTBLs are simulated—one with trade wind shallow cumuli, and the other with nocturnal marine stratocumuli. Approximations to the ensemble-mean budgets of the Reynolds-stress components, of the fluxes of two quasi-conservative scalars, and of the scalar variances and covariance are computed by averaging the LES data over horizontal planes and over several hundred time steps. Importantly, the subgrid scale contributions to the budget terms are accounted for. Analysis of the LES-based second-moment budgets reveals, among other things, a paramount importance of the pressure scrambling terms in the Reynolds-stress and scalar-flux budgets. The pressure-strain correlation tends to evenly redistribute kinetic energy between the components, leading to the growth of horizontal-velocity variances at the expense of the vertical-velocity variance which is produced by buoyancy over most of both CTBLs. The pressure gradient-scalar covariances are the major sink terms in the budgets of scalar fluxes. The third-order transport proves to be of secondary importance in the scalar-flux budgets. However, it plays a key role in maintaining budgets of TKE and of the scalar variances and covariance. Results from the second-moment budget analysis suggest that the accuracy of description of the CTBL structure within the second-order closure framework strongly depends on the fidelity of parameterizations of the pressure scrambling terms in the flux budgets and of the third-order transport terms in the variance budgets.
