description: We consider the spin-1/2 antiferromagnetic Heisenberg model on the two-dimensional square-kagome lattice with almost dispersionless lowest magnon band. For a general exchange coupling geometry we elaborate low-energy effective Hamiltonians which emerge at high magnetic fields. The effective model to describe the low-energy degrees of freedom of the initial frustrated quantum spin model is the (unfrustrated) square-lattice spin-1/2 $XXZ$ model in a $z$-aligned magnetic field. For the effective model we perform quantum Monte Carlo simulations to discuss the low-temperature properties of the square-kagome quantum Heisenberg antiferromagnet at high magnetic fields. We pay special attention to a magnetic-field driven Berezinskii-Kosterlitz-Thouless phase transition which occurs at low temperatures.

title: Essays in Quantitative Family Economics - Labor Supply, Risk Sharing and Welfare
Creators: name: Gravert, Jan Hendrik
Publisher: name: Bergische Universität Wuppertal
Year: 2020

description: This thesis analyzes intra-household behavior and consequences in quantitative models of the family. The focus is (i) the estimation of Frisch labor-supply elasticities in couple households and (ii) inefficiencies arising from limited commitment between spouses. Chapter I gives a brief overview of different model types of intra-household behavior and an overview of the thesis. Chapter II (joint work with Christian Bredemeier and Falko Jüßen) deals with the biases in conventional estimates of Frisch labor-supply elasticities in presence of borrowing constraints. The chapter develops an incomplete-markets model with two-earner households and derives a new estimation approach for the Frisch elasticity that yields unbiased estimates even in samples that include borrowing-constrained households. The approach takes the form of a simple interaction-term model with minimum data requirements. Chapter III uses an incomplete-markets model to quantify how strongly limited commitment reduces individuals' possibilities to share risk within the household. Additionally, households are identified for whom intra-household risk sharing is particularly aggravated by limited commitment. The results imply an additional demand for other forms of insurance such as public insurance and provide a rationale for means-testing that targets individuals rather than households. Chapter IV (joint work with Christian Bredemeier and Falko Jüßen) investigates how Frisch labor-supply elasticities can be estimated when commitment between spouses is limited. The chapter shows that proxying individual consumption, which theory calls for as a control variable but which is unavailable in most data sets, by household consumption causes substantial biases in estimated Frisch elasticities. Improved estimation approaches are developed which reduce or fully eliminate this bias. Chapter V (joint work with Christian Bredemeier and Falko Jüßen) introduces limited commitment into a quantitative dual-earner heterogeneous-agents incomplete-markets economy and uses this framework to study the inefficiencies in savings and risk-sharing behavior due to limited commitment. Chapter VI summarizes the main results of the thesis.

title: Development of Analytical Methods to Investigate the Formation of Oxylipins during Oxidative Stress and Inflammation
Creators: name: Rund, Katharina M.
Publisher: name: Bergische Universität Wuppertal
Year: 2020

description: In the human body a vast number of oxidized polyunsaturated fatty acids (PUFA) is enzymatically and autoxidatively formed by conversion of n3- and n6-PUFA. Several of these oxylipins act as potent lipid mediators in the regulation of multiple physiological processes such as inflammation, endothelial and kidney function. However, the role of the overall oxylipin pattern is still only poorly understood. Thus, investigating the modulation of the oxylipin pattern in (patho)physiology, e.g. under oxidative stress or inflammation, or in response to dietary modulation, contributes to a better understanding of the functional role of oxylipins being both marker and mediator of the physiological status. In the first part of this thesis a comprehensive targeted LC-ESI(-)-MS/MS method is described for the sensitive and reliable quantification of a broad set of non-enzymatically and enzymatically formed oxylipins from all major formation branches derived from all biologically relevant PUFA precursors. In addition to the optimization of instrumental parameters, the influence of pre-analytical blood storage and transport conditions typically occurring in the clinical routine on the oxylipin pattern is characterized. In the second part of this thesis the established analytical method is applied to study the formation of oxylipins in the context of oxidative stress and inflammation. Focusing on the autoxidative formation of trans-epoxy-PUFA, the potential use of the trans/cis-epoxy-PUFA ratio as alternative oxidative stress marker is investigated. Therefore, this ratio is correlated with the formation of isoprostanes – common markers of oxidative stress – using (i) tert-butyl hydroperoxide as inducer of oxidative stress in three human carcinoma cell lines as well as in (ii) the in vivo model organism C. elegans and (iii) renal ischemia reperfusion injury in mice. Finally, the anti-inflammatory properties of n3-PUFA are investigated using a murine model of renal ischemia reperfusion injury causing both oxidative stress and inflammation. The modulation of the PUFA and oxylipin pattern is analyzed in combination with clinical and histological markers of kidney damage and inflammation.

description: The design, projected performance and status of NTE (NOT Transient Explorer) is described. NTE
 is in reality three independent instruments mounted together at the Cassegrain focus of the NOT:
 NTE-VIS-imager, NTE-IR-imager and NTE-spectrograph. The two imagers can be used in parallel
 via a dichroic and provides a FoV of 6’ with a sampling of 0.18”/pix. They are in performance
 very similar to AlFOsc and NOTCam, respectively. The NTE spectrograph is a cross-dispersed
 and covers the spectral range 320 nm - 2430 nm in a single exposure, through 18 spectral orders,
 with a 23” long slit. The spectrograph utilizes CCDs in the visible/UV and an H2RG detector from
 Teledyne in the IR, with plate scales of 0.23” and 0.40”, respectively. NTE is expected to have first
 light in 2024.

description: We explore the feasibility of using the atmosphere of Jupiter to detect Ultra-High-Energy Cosmic Rays (UHECR's). The large surface area of Jupiter allows us to probe cosmic rays of higher energies than previously accessible. Cosmic ray extensive air showers in Jupiter's atmosphere could in principle be detected by the Large Area Telescope (LAT) on the Fermi observatory. In order to be observed, these air showers would need to be oriented toward the Earth, and would need to occur sufficiently high in the atmosphere that the gamma rays can penetrate. We demonstrate that, under these assumptions, Jupiter provides an effective cosmic ray "detector" area of $3.3 \times 10^7$ km$^2$. We predict that Fermi-LAT should be able to detect events of energy $>10^{21}$ eV with fluence $10^{-7}$ erg cm$^{-2}$ at a rate of about one per month. The observed number of air showers may provide an indirect measure of the flux of cosmic rays $\gtrsim 10^{20}$ eV. Extensive air showers also produce a synchrotron signature that may be measurable by ALMA. Simultaneous observations of Jupiter with ALMA and Fermi-LAT could be used to provide broad constraints on the energies of the initiating cosmic rays.

description: We study an isothermal system of semi-degenerate self-gravitating fermions in general relativity. Such systems present mass density solutions with a central degenerate core, a plateau and a tail which follows a power law behaviour $r^{-2}$. The different solutions are governed by the free parameters of the model: the degeneracy and temperature parameters at the center, and the particle mass $m$. We then analyze in detail the free parameter space for a fixed $m$ in the keV regime, by studying the one-parameter sequences of equilibrium configurations up to the critical point, which is represented by the maximum in a central density ($ρ_0$) Vs. core mass ($M_c$) diagram. We show that for fully degenerate cores, the known expression for the critical core mass $M_c^{cr}\propto m_{pl}^3/m^2$ is obtained, while instead for low degenerate cores, the critical core mass increases showing the temperature effects in a non linear way. The main result of this work is that when applying this theory to model the distribution of dark matter in galaxies from the very center up to the outer halos, we do not find any critical core-halo configuration of self-gravitating fermions, which be able to explain the super massive dark object in their centers together with an outer halo simultaneously.

In the production process of selenium-enriched eggs, different selenium sources, additive doses, feeding time, and the addition of other vitamins, trace elements, and methionine in the diet will influence the deposition of selenium in eggs. Through this review, it is intended to provide a reference for the practical, safe and economical production of selenium-enriched eggs.

description: We consider biased $(1:b)$ Avoider-Enforcer games in the monotone and strict versions. In particular, we show that Avoider can keep his graph being a forest for every but maybe the last round of the game if $b \geq 200 n \ln n$. By this we obtain essentially optimal upper bounds on the threshold biases for the non-planarity game, the non-$k$-colorability game, and the $K_t$-minor game thus addressing a question and improving the results of Hefetz, Krivelevich, Stojaković, and Szabó. Moreover, we give a slight improvement for the lower bound in the non-planarity game.

Die empirische Analyse zielt hierbei auf die Beantwortung der Frage ab, wie die auf Basis von ökonomischen und personenspezifischen Faktoren gebildete Vertrauenserwartung die Transaktionsbereitschaft bzw. Aktienkaufbereitschaft professioneller Investoren beeinflusst. Basis für die Untersuchung ist ein Faktorieller Survey, der insgesamt aus 16 verschiedenen Situationsbeschreibungen, sogenannten Vignetten, besteht. Im Ergebnis zeigt sich, dass der Zusammenhang zwischen ökonomischem Vertrauen und Transaktionsaktionsbereitschaft grundsätzlich in Abhängigkeit von personenspezifischen Vertrauensfaktoren, wie z. B. der generellen Vertrauensneigung, variiert. Somit beeinflusst das Vertrauenskonstrukt selbst professionelle Anleger im Rahmen ihrer Entscheidungen.

description: In this paper we consider a non-linear Schroedinger equation with a cubic nonlinearity and a multi-dimensional double well potential. In the semiclassical limit the problem of the existence of stationary solutions simply reduces to the analysis of a finite dimensional Hamiltonian system which exhibits different behavior depending on the dimension. In particular, in dimension 1 the symmetric stationary solution shows a standard pitchfork bifurcation effect, while in dimension 2 and 3 new asymmetrical solutions associated to saddle points occur. These last solutions are localized on a single well and this fact is related to the phase transition effect observed in Bose-Einstein condensates in periodical lattices.

description: Nowadays digital image compression and decompression techniques are very much important. So our aim is to calculate the quality of face and other regions of the compressed image with respect to the original image. Image segmentation is typically used to locate objects and boundaries (lines, curves etc.)in images. After segmentation the image is changed into something which is more meaningful to analyze. Using Universal Image Quality Index(Q),Structural Similarity Index(SSIM) and Gradient-based Structural Similarity Index(G-SSIM) it can be shown that face region is less compressed than any other region of the image.

description: The coupling of photons with (ultra-) relativistic atomic nuclei is presented in two particular circumstances: very high electromagnetic fields and very short photon pulses. We consider a typical situation where the (bare) nuclei (fully stripped of electrons) are accelerated to energies ~1TeV per nucleon (according to the state of the art at LHC, for instance) and photon sources like petawatt lasers \simeq1eV -radiation (envisaged by ELI-NP project, for instance), or free-electron laser ~10keV -radiation, or synchrotron sources, etc. In these circumstances the nuclear scale energy can be attained, with very high field intensities. In particular, we analyse the nuclear transitions induced by the radiation, including both one- and two-photon processes, as well as the polarization-driven transitions which may lead to giant dipole resonances. The nuclear (electrical) polarization concept is introduced. It is shown that the perturbation theory for photo-nuclear reactions is applicable, although the field intensity is high, since the corresponding interaction energy is low and the interaction time (pulse duration) is short. It is also shown that the description of the giant nuclear dipole resonance requires the dynamics of the nuclear electrical polarization degrees of freedom.

description: IRAS18197-1118 is a stellar-like object that has been classified as a planetary nebula from its radio continuum emission and high [SIII]9532 to Paschen9 line intensity ratio, as derived from direct images. We present intermediate- and high-resolution, optical spectroscopy, VLA 8.46 GHz radio continuum data, and narrow-band optical images of IRAS18197-1118 aimed at confirming its planetary nebula nature, and analyzing its properties. The optical spectrum shows that IRAS18197-1118 is a medium-excitation planetary nebula suffering a high extinction (c(H_beta) ~3.37). The optical images do not resolve the object but the 8.46 GHz image reveals an elliptical shell of ~2.7x1.6 arcsec^2 in size, a compact central nebular region, and possible bipolar jet-like features, indicating several ejection events. The existence of a compact central nebula makes IRAS18197-1118 singular because this kind of structure is observed in a few PNe only. An expansion velocity ~20 km/s and a systemic velocity (LSR) ~+95 km/s are obtained for the object. An electron density of ~3.4x10^4 cm-3 and an ionized mass of ~2.1x10^-2 M_sun are deduced from the 8.46 GHz radio continuum data for an estimated statistical distance of 6 kpc. Helium abundance is high but nitrogen is not enriched, which is not consistently reproduced by evolutionary models, suggesting different abundances in the elliptical shell and central region. The properties of IRAS18197-1118 indicate a relatively young planetary nebula, favor a distance of >~6 kpc, and strongly suggest that it is an inner-disc planetary nebula.

description: Targeted searches of continuous waves from spinning neutron stars normally assume that the frequency of the gravitational wave signal is at a given known ratio with respect to the rotational frequency of the source, e.g. twice for an asymmetric neutron star rotating around a principal axis of inertia. In fact this assumption may well be invalid if, for instance, the gravitational wave signal is due to a solid core rotating at a slightly different rate with respect to the star crust. In this paper we present a method for {\it narrow-band} searches of continuous gravitational wave signals from known pulsars in the data of interferometric detectors. This method assumes source position is known to high accuracy, while a small frequency and spin-down range around the electromagnetic-inferred values is explored. Barycentric and spin-down corrections are done with an efficient time-domain procedure. Sensitivity and computational efficiency estimates are given and results of tests done using simulated data are also discussed.

description: This study examines how corruption in higher education (HE) informs the brain drain phenomenon in North Macedonia. Through six interviews with college-educated students who emigrated from the country, the research uncovers the reasons behind their emigration decision and highlights the pervasive nature of corruption within HE. Findings reveal that corruption, along with limited career opportunities and distrust at the systemic level, motivates individuals to seek a better life abroad. The normalization of corruption and a lack of motivation to effect change further contribute to the emigration of highly skilled individuals. The study recommends measures such as establishing integrity units within universities and addressing political party involvement to combat these issues.

description: Using the Kubo formalism, the magnetic properties of the system in the linear regime have been investigated. Mainly the effect of non-magnetic substrate on the spin susceptibility is calculated. Results show that the Rashba coupling interaction has a central role in the magnetic response function of the system and it is really remarkable since this type of spin orbit coupling can be effectively controlled by an external gate voltage. Most importantly it was shown that, in the presence of the Rashba interaction a magnetic phase transition could be observed. This magnetic phase corresponds to a magnetic order of conduction electrons that takes place at some especial frequency of external magnetic field.

We also find out that the two modes have a non-uniform spatial distribution.

description: With the rapid development of Internet technology, the importance of blockchain technology has become increasingly prominent. Faced with this situation, extensive research has been carried out at home and abroad. Through the analysis of relevant literature on blockchain in recent years, it is found that there are many research results of blockchain technology in medical care, finance, education, etc., but its application in the field of resource allocation efficiency is rare. From the existing studies on the influencing factors of resource allocation efficiency in China, it is found that there are significant differences in resource allocation efficiency between China and some developed countries or between various provinces and cities of China.
Two-temperature continuum thermomechanics of deforming amorphous solids

description: There is an ever-growing need for predictive models for the elasto-viscoplastic deformation of solids. Our goal in this paper is to incorporate recently developed out-of-equilibrium statistical concepts into a thermodynamically consistent, finite-deformation, continuum framework for deforming amorphous solids. The basic premise is that the configurational degrees of freedom of the material --- the part of the internal energy/entropy that corresponds to mechanically stable microscopic configurations --- are characterized by a configurational temperature that might differ from that of the vibrational degrees of freedom, which equilibrate rapidly with an external heat bath. This results in an approximate internal energy decomposition into weakly interacting configurational and vibrational subsystems, which exchange energy following a Fourier-like law, leading to a thermomechanical framework permitting two well-defined temperatures. In this framework, internal variables that carry information about the state of the material equilibrate with the configurational subsystem, are explicitly associated with energy and entropy of their own, and couple to a viscoplastic flow rule. The coefficients that determine the rate of flow of entropy and heat between different internal systems are proposed to explicitly depend on the rate of irreversible deformation. As an application of this framework, we discuss two constitutive models for the response of glassy materials, a simple phenomenological model and a model related to the concept of Shear-Transformation-Zones as the basis for internal variables. The models account for several salient features of glassy deformation phenomenology. Directions for future investigation are briefly discussed.

description: Significant contamination events that have occurred in drinking water distribution systems over the last decade have raised public concern and the attention of regulators seeking to protect the safety of municipal drinking water systems. In response, municipalities are interested in using online, real-time continuous sensors to monitor water quality in locations throughout their distribution systems. Despite the significant effort being devoted to developing low-cost and energy-efficient water quality sensors, the reliability and utility of commercial water quality sensors for monitoring municipal drinking water systems have not been validated. In this study, the performance of a real-time, commercial sensor system was compared to conventional laboratory analysis of grab samples collected from fire hydrants in a chloraminated drinking water distribution system. Relationships between sensor output and direct/indirect laboratory analysis were established in both laboratory experiments and field applications. Finally, the stability of the water quality sensor was examined by analyzing the temporal and spatial changes in output over a three-week fire hydrant trial. The results of the study found that the ORP sensors are insensitive to changes in chloramine changes between 1.5 and 2.5 mg/L Cl₂ in an oxic system. Overall, the optical sensors in the commercial systems performed poorly for monitoring water quality in the DWDS when the samples were drawn from fire hydrants. Transient pressure changes in the barrel of the fire hydrant released particles that fouled the optical sensor units. Recommendations for real-time water quality sensors installation, performance validation, and data interpretation for municipalities interested in using fire hydrants as DWDS sampling points are provided based on a case study conducted in a chloraminated drinking water distribution system.

description: We report the detection of extremely broad emission toward two molecular clumps in the Galactic central molecular zone. We have mapped the Sagittarius C complex ($-0^\circ.61 < l < -0^\circ.27$, $-0^\circ.29 < b < 0^\circ.04$) in the HCN $J$ = 4--3, $\mathrm{^{13}CO}$ $J$ = 3--2, and $\mathrm{H^{13}CN}$ $J$ = 1--0 lines with the ASTE 10 m and NRO 45 m telescopes, detecting bright emission with $80\mbox{--}120$\ $\mathrm{km\,s^{-1}}$ velocity width (in full-width at zero intensity) toward CO$-0.30$$-0.07$ and CO$-0.40$$-0.22$, which are high velocity compact clouds (HVCCs) identified with our previous CO $J$ = 3--2 survey. Our data reveal an interesting internal structure of CO$-0.30$$-0.07$ comprising a pair of high velocity lobes. The spatial-velocity structure of CO$-0.40$$-0.22$ can be also understood as multiple velocity component, or a velocity gradient across the cloud. They are both located on the rims of two molecular shells of about 10 pc in radius. Kinetic energies of CO$-0.30$$-0.07$ and CO$-0.40$$-0.22$ are $\left(0.8\mbox{--}2\right)\times10^{49}$ erg and $\left(1\mbox{--}4\right)\times10^{49}$ erg, respectively. We propose several interpretations of their broad emission: collision between clouds associated with the shells, bipolar outflow, expansion driven by supernovae (SNe), and rotation around a dark massive object. There scenarios cannot be discriminated because of the insufficient angular resolution of our data, though the absence of visible energy sources associated with the HVCCs seems to favor the cloud--cloud collision scenario. Kinetic energies of the two molecular shells are $1\times10^{51}$ erg and $0.7\times10^{51}$ erg, which can be furnished by multiple SN or hypernova explosions in $2\times10^5$ yr. These shells are candidates of molecular superbubbles created after past active star formation.

description: Interest in many-core architectures applied to real time selections is growing in High Energy Physics (HEP) experiments. In this paper we describe performance measurements of many-core devices when applied to a typical HEP online task: the selection of events based on the trajectories of charged particles. We use as benchmark a scaled-up version of the algorithm used at CDF experiment at Tevatron for online track reconstruction - the SVT algorithm - as a realistic test-case for low-latency trigger systems using new computing architectures for LHC experiment. We examine the complexity/performance trade-off in porting existing serial algorithms to many-core devices. We measure performance of different architectures (Intel Xeon Phi and AMD GPUs, in addition to NVidia GPUs) and different software environments (OpenCL, in addition to NVidia CUDA). Measurements of both data processing and data transfer latency are shown, considering different I/O strategies to/from the many-core devices.

description: Land use in lake basins has an important impact on the sustainable development of society, economy and ecology. Based on the literature induction method, this paper systematically summarized the current status of land use research in lake basins from six aspects: temporal and spatial changes, effects, driving factors, optimization research, and the application of remote sensing techniques in lake land use research. Correspondingly, three problems were proposed: lack of refined research on land use changes in lake basins, imperfect theoretical research on lake land use optimization research, and weak land type extraction techniques based on remote sensing images. It is believed that the future research on lake land use should focus on strengthening the refinement of land use change research in lake basins, further improving the theoretical and practical research on land use optimization in lake basins based on a variety of related theories, and further improving the interpretation algorithms of remote sensing images.

description: An experimental demonstration of two-qutrit state tomography via one-qutrit symmetric informationally complete positive operator-valued measure (SIC-POVM) is presented. A two-qutrit state is encoded in the transversal paths of a spontaneous parametric down-converted photon pair. A spatial light modulator allows to implement the necessary 81 POVM elements to reconstruct the state. The quality of the reconstruction is evaluated by comparing independent measurements with the predicted results calculated with the reconstructed state. Entanglement in the system is calculated via negativity and generalized robustness from the two-qutrit reconstructed density operator.

description: We present a test for spin-orbit alignment for the host stars of 25 candidate planetary systems detected by the {\it Kepler} spacecraft. The inclination angle of each star's rotation axis was estimated from its rotation period, rotational line broadening, and radius. The rotation periods were determined using the {\it Kepler} photometric time series. The rotational line broadening was determined from high-resolution optical spectra with Subaru/HDS. Those same spectra were used to determine the star's photospheric parameters (effective temperature, surface gravity, metallicity) which were then interpreted with stellar-evolutionary models to determine stellar radii. We combine the new sample with the 7 stars from our previous work on this subject, finding that the stars show a statistical tendency to have inclinations near 90$^\circ$, in alignment with the planetary orbits. Possible spin-orbit misalignments are seen in several systems, including three multiple-planet systems (KOI-304, 988, 2261). Ideally these systems should be scrutinized with complementary techniques---such as the Rossiter-McLaughlin effect, starspot-crossing anomalies or asteroseismology---but the measurements will be difficult owing to the relatively faint apparent magnitudes and small transit signals in these systems.

title: Wirkung der Mitwirkung - Messung der Effektivität von Bürgerbeteiligung am Beispiel der Stadt Heidelberg
Creators: name: Nebenführ, Pascal
Publisher: name: Bergische Universität Wuppertal
Year: 2020

description: Seit den Protesten rund um den Bau des Bahnprojekts Stuttgart 21 werden Politik und Verwaltung auf kommunaler Ebene mit beständig stärker werdenden Beteiligungswünschen der Bürgerinnen und Bürger konfrontiert. Aber auch in der internationalen Partizipationsforschung taucht der Begriff der Bürgerbeteiligung in den letzten zehn bis 15 Jahren immer beharrlicher auf. In direkter Reaktion hierauf befasst sich die Stadt Heidelberg, als eine der ersten Kommunen deutschlandweit, seit dem Jahr 2010 intensiv mit der Beteiligung ihrer Bürgerinnen und Bürger am politischen Entscheidungsfindungsprozess. Die deutschsprachige Forschung allerdings konzentriert sich lediglich auf die inhaltliche Ausgestaltung von Bürgerbeteiligung anhand einer Vielzahl an Handbüchern, Checklisten und Leitlinien für die kommunale Praxis. Wissenschaftliche Überlegungen zu deren Wirksamkeit werden so gut wie gar nicht angestellt. Die Dissertation „Wirkung der Mitwirkung - Messung der Effektivität von Bürgerbeteiligung am Beispiel der Stadt Heidelberg -“ von Pascal Nebenführ geht aufgrund dessen anhand einer quantitativen Datenanalyse der Fragestellung nach, welchen Grad an Effektivität Bürgerbeteiligung in der Stadt Heidelberg innehat. Der Autor entwickelt hierfür zuerst eine an Benjamin Barbers (1994) starker Demokratie orientierte normative Definition von Bürgerbeteiligung. Anschließend werden, bezugnehmend auf die Publikationen von Archon Fung (2003) sowie Lyn Carson und Phillip Hart (2005), Beurteilungsdimensionen effektiver Bürgerbeteiligung (Empowerment, Efficacy, Inclusion und Quality) entworfen. Darauf aufbauend konstruiert der Autor ein empirisches Messmodell, welches im letzten Teil der Arbeit anhand von Primär- und Sekundärdaten auf die Stadt Heidelberg angewandt wird. Als Ergebnis der Arbeit zeigt sich unter anderem, dass die Effektivität von Partizipationsverfahren von vielen unterschiedlichen Einflussfaktoren und Parametern abhängig ist, die nicht alle einer Messung zugeführt werden können. Zudem wird deutlich, dass Kommunen vorrangig bei den Beurteilungsdimensionen Inclusion und Quality ansetzen müssen, um die Wirksamkeit von Bürgerbeteiligung zu erhöhen. Beispielsweise durch den Partizipationsprozess begleitende Maßnahmen wie eine aleatorische Teilnehmerauswahl oder die Zahlung von Aufwandsentschädigungen. Der Autor kommt abschließend zu der Überzeugung, dass die Kombination aus normativen und quantitativen Untersuchungen das Verständnis von Bürgerbeteiligung auf kommunaler Ebene erheblich verbessern wird.

description: As applied to the numerical simulation of electron transport and scattering processes in semiconductors an efficient model describing the scattering of electrons by the ionized impurities is proposed. On the example of GaAs at 77 and 300 K and Si at 300 K the dependencies of low-field electron mobility on the donor impurity concentration in the semiconductors are calculated in the framework of proposed model as well as in the framework of such most frequently used applied models as the Conwel-Weisskopf model and the Brooks-Herring one. After comparing the calculation results with the well-known experimental data it has been ascertained that the best agreement between the theory and experiment is achieved with application of the proposed model.
