description: The following tables represent effort, retained catch (kept) and discard as reported on longline log sheets for the Hawaii limited-access longline fishery. To satisfy confidentiality RFMO reporting standards, data from the California-based longline fishery is also included in this report. Effort and catch statistics are summarized from logbook data submitted to the PIFSC, FRMD and are based on date of longline haul. The statistics originate from an Oracle table LLDS_REPORT_STATS_HICA database extraction conducted on 3 May 2016. When a statistic (number of vessels, trips) can involve dates of haul in 2 summary periods (i.e., years, semi-annual, quarters, etc.) the item is counted in both summary periods. Thus, a trip total is for 'partial and completed' trips. As such, these are not additive statistics (i.e., sum of 4 quarters is not the total for the year, etc).

description: This paper deals with adaptive synchronization of chaos in the presence of time-varying communication-delays. We consider two bidirectionally coupled systems that seek to synchronize through a signal that each system sends to the other one and is transmitted with an unknown time-varying delay. We show that an appropriate adaptive strategy can be devised that is successful in dynamically identifying the time-varying delay and in synchronizing the two systems. The performance of our strategy with respect to the choice of the initial conditions and the presence of noise in the communication channels is tested by using numerical simulations. Another advantage of our approach is that in addition to estimating the communication-delay, the adaptive strategy could be used to simultaneously identify other parameters, such as e.g., the unknown time-varying amplitude of the received signal.

Εξετάσαμε τις διδασκαλίες του, που έχουν σχέση με την Αγία Τριάδα και την προβολή του Θεού ως στοργικού Πατέρα, ο οποίος μεριμνά για όλα τα παιδιά Του. Στη συνέχεια παρουσιάσαμε τις απόψεις του για το πρόσωπο του Χριστού, ο οποίος είναι πολυαδικημένος και πολυταπεινωμένος. Ακόμη αναφερθήκαμε στη διδασκαλία του για τη δημιουργία του Αδάμ και της Εύας, το Προπατορικό αμάρτημα και τους τρόπους, με τους οποίους μπορεί ο άνθρωπος να φτάσει στη θέωση. Ένα άλλο θέμα που θίξαμε ήταν το πώς περιγράφεται η Εκκλησία (ως άρτια πνευματική οικοδομή, ως σκάφος του Χριστού, ως Σώμα του Χριστού κλπ) και τα μυστήριά της. Ασχοληθήκαμε επιπλέον με τα θέματα του θανάτου, της Δευτέρας Παρουσίας του Χριστού, της Τελικής Κρίσης, του Παραδείσου και της Κόλασης.
description: The aim of the present Thesis was the study and presentation of the teaching of Saint Paisios of Mount Athos on issues related to aspects of the Orthodox doctrine. We examined his teachings about the Trinity and the projection of God as a loving Father who cares for all His children. We then presented his views on the person of Christ, who was extremely wronged and humiliated. We also referred to his teaching about the creation of Adam and Eve, the original sin, and the ways in which man can reach theosis. Another question we raised was how the Church is described (as a perfect spiritual edifice, as a vessel of Christ, as the Body of Christ, etc.) and its sacraments. We also dealt with the issues of death, the Second Coming of Christ, the Final Judgment, Paradise and Hell.

Ειδικά για τη ΣΤ΄ τάξη διαπιστώθηκε ότι περισσότερα από τα μισά κείμενα εμπεριέχουν στοιχεία ετερότητας.
description: The present thesis attempts to highlight the way in which diversity is embodied in the textbooks of Modern Greek Language in Greek primary education. Having as a basis and motive the multiculturalism and the migratory movements in the Greek territory, it is attempted to understand and interpret the concept of heterogeneity, as well as that of identity. In this direction, an attempt is then made to identify elements related to diversity, identity and multiculturalism/interculturalism in the textbooks of students of the six grades of primary school in the subject of Modern Greek Language. Thus, for the purposes of the research of this thesis, qualitative content analysis of the student's book in each grade of primary school was used and it was found that diversity in some grades, especially in the three oldest grades, seems to play a prominent role. For the 6th grade, it was found that more than half of the texts contain elements of diversity.

description: This Master Thesis Project discusses the subject of Health Protocols in Preschool Education and Care, the epidemiological characteristics of Preschool Care facilities in relation to different infectious diseases that mainly target young children as well as the more specific case of Covid-19. The turbulent public health status of the last few years has raised questions regarding the adequacy of the health protocols implemented on various settings, one of those of outmost importance being Preschool Education and Care, as well as the significance of Health Education strategies for young children. In order to find out more information regarding the matters above, a research in the form of a questionnaire was conducted, with the respondents being parents/guardians of preschool age children. The results showed that parents/guardians believe that Health Education is greatly significant during Preschool Education, as well as that the hygiene guidelines up until before Covid-19 might have been insufficient.

Cross-validation of PV system simulation software

Publisher: name: WIP

description: Simulation software plays a critical role for planning, optimizing and evaluating PV systems—and for gaining investor confidence. Does it matter which software is used? Most, if not all, core calculations are based on the same published models (some of them very old), and most software documentation is open about the models and methods that are implemented. So in theory, if we simulate the same system with the same model choices and the same assumptions, each software program should produce the same results. Our aim is to check this theory, identify precisely at which model steps differences occur, and determine how each of these differences contributes to overall differences in predicted yield. 
Our general approach to this task is to define a range of test systems representing different technologies, products, locations and design variations; simulate them using each software; and compare the simulation output at each stage of the model chain—not just the final output. Fortunately each software option is able to generate an output file with such details, thus making this type of analysis possible. An initial challenge was to establish the equivalence between the terminology used in the different programs for system definitions, model parameters, simulation options and output variables. Having done this, we can now operate and evaluate all the software with a common nomenclature for input and output.

description: We investigate in detail the probability distribution function (pdf) of the proper-motion measurement errors in the SDSS+USNO-B proper-motion catalog of \citet{mun04} using clean quasar samples. The pdf of the errors is well-represented by a Gaussian core with extended wings, plus a very small fraction ($<0.1%$) of "outliers". We find while formally the pdf could be well-fit by a five-parameter fitting function, for many purposes it is also adequately to represent the pdf with a one-parameter approximation to this function. We apply this pdf to the calculation of the confidence intervals on the true proper motion for a SDSS+USNO-B proper motion measurement, and discuss several scientific applications of the SDSS proper motion catalogue. Our results have various applications in studies of the galactic structure and stellar kinematics. Specifically, they are crucial for searching hyper-velocity stars in the Galaxy.

description: We have grown single crystal samples of Co substituted CaFe2As2 using an FeAs flux and systematically studied the effects of annealing/quenching temperature on the physical properties of these samples. Whereas the as-grown samples (quenched from 960C) all enter the collapsed tetragonal phase upon cooling, annealing/quenching temperatures between 350C and 800C can be used to tune the system to low temperature antiferromagnetic/orthorhomic or superconducting states as well. The progression of the transition temperature versus annealing/quenching temperature (T-T$_{anneal}$) phase diagrams with increasing Co concentration shows that, by substituting Co, the antiferromagnetic/orthorhombic and the collapsed tetragonal phase lines are separated and bulk superconductivity is revealed. We established a 3D phase diagram with Co concentration and annealing/quenching temperature as two independent control parameters. At ambient pressure, for modest x and T$_{anneal}$ values, the Ca(Fe1-xCox)2As2 system offers ready access to the salient low temperature states associated with Fe-based superconductors: antiferromagnetic/orthorhombic, superconducting, and non-magnetic/collapsed tetragonal.

description: The sensitivity kernels in the Earth’s inner core for PKIKP and PKIIKP waves using the DSM Kernel Suite algorithm and 128 processor cores were calculated. In the calculation process, a database of 725634 strain Green’s tensors was created. It is estimated that the thickness of the sensitivity tube for the PKIKP wave in the upper part of the inner core is about 200 km. It is shown that in the antipode, the inhomogeneities at the base of the outer core have a much greater effect than inhomogeneities in the inner core for the PKIIKP waves travel times under the condition of uniform volume. It was demonstrated that the inhomogeneities of the shear wave velocity in the source region cause stronger oscillations in the fragment of the seismogram containing the PKIIKP wave in the antipode than the inhomogeneities in the upper part of the inner core under the same condition.

description: Using dimensional analysis techniques we present an extension of Newton's gravitational theory built under the assumption that Milgrom's acceleration constant is a fundamental quantity of nature. The gravitational force converges to Newton's gravity and to a MOND-like description in two different mass and length regimes. It is shown that a modification on the force sector (and not in the dynamical one as MOND does) is more convenient and can reproduce and predict different phenomena usually ascribed to dark matter at the non-relativistic level.

Value of pumped-storage hydro for wind power integration in the British Columbia hydroelectric system
Creators: name: Rivas Guzman, Humberto Andres
Publisher: name: University of British Columbia
Year: 2010

description: In the next few years, the province of British Columbia will experience the installation of significant amounts of wind power as part of BC Hydro calls for clean renewable energy resources. The inherent variability and uncertainty of wind power will impact the operation of the BC Hydro system. If the system loses some of its flexibility in the process of integrating more wind power, there are costs that need to be assessed and recognized. Of particular interest are the costs associated with incremental wind reserves to manage wind variability and the cost associated with foregoing day-ahead market opportunities due to the wind forecast error. Pumped-storage hydro systems have been proposed as a good technology to complement wind generation due to their ability to manage wind energy imbalances over time. This research investigated the feasibility of expanding an existing hydropower system by installing a pumped-storage hydro system to mitigate the impacts of integrating wind in a large scale hydro system. This study proposed the installation of an additional pump station, equipped with automatic generation control capabilities. Two optimization models were developed to assess the benefits of the pumped-storage hydro system and the impacts of wind integration: A long-term mixed integer optimization, and a short-term stochastic linear optimization models to simulate BC Hydro short-term operations considering different load and wind stochastic scenarios. Both models are an extension of the BC Hydro Generalized Optimization Model (GOM), which is a deterministic linear optimization model that has been used to assess many capital investments and water use planning studies for the BC Hydro system. The model proposed in this research included a stochastic extension of GOM. Optimization runs of the BC Hydro’s hourly system operation for one year, with and without the pumped-storage hydro system were carried out and their outcomes were compared to estimate the overall benefits of the pump-storage system. The results indicated that there are benefits of installing a pumped-storage hydro system in the BC Hydro system to manage and to reduce wind power integration impacts. The benefits increased as more wind power is installed in the BC Hydro system.
Baroclinic Instability on Hot Extrasolar Planets

description: We investigate baroclinic instability in flow conditions relevant to hot extrasolar planets. The instability is important for transporting and mixing heat, as well as for influencing large-scale variability on the planets. Both linear normal mode analysis and non-linear initial value calculations are carried out -- focusing on the freely-evolving, adiabatic situation. Using a high-resolution general circulation model (GCM) which solves the traditional primitive equations, we show that large-scale jets similar to those observed in current GCM simulations of hot extrasolar giant planets are likely to be baroclinically unstable on a timescale of few to few tens of planetary rotations, generating cyclones and anticyclones that drive weather systems. The growth rate and scale of the most unstable mode obtained in the linear analysis are in qualitative, good agreement with the full non-linear calculations. In general, unstable jets evolve differently depending on their signs (eastward or westward), due to the change in sign of the jet curvature. For jets located at or near the equator, instability is strong at the flanks -- but not at the core. Crucially, the instability is either poorly or not at all captured in simulations with low resolution and/or high artificial viscosity. Hence, the instability has not been observed or emphasized in past circulation studies of hot extrasolar planets.

description: Detailed chemical abundances for twenty one elements are presented for four red giants in the anomalous outer halo globular cluster Palomar 1 ($R_{\rm{GC}} = 17.2$ kpc, $Z=3.6$ kpc) using high-resolution (R=36000) spectra from the High Dispersion Spectrograph (HDS) on the Subaru Telescope. Pal 1 has long been considered unusual because of its low surface brightness, sparse red giant branch, young age, and its possible association with two extragalactic streams of stars---this paper shows that its chemistry further confirms its unusual nature. The mean metallicity of the four stars, $[\rm{Fe/H}] = -0.60 \pm 0.01$, is high for a globular cluster so far from the Galactic center, but is low for a typical open cluster. The [$α$/Fe] ratios, though in agreement with the Galactic stars within the $1σ$ errors, agree best with the lower values in dwarf galaxies. No signs of the Na/O anticorrelation are detected in Pal 1, though Na appears to be marginally high in all four stars. Pal 1's neutron capture elements are also unusual: its high [Ba/Y] ratio agrees best with dwarf galaxies, implying an excess of second-peak over first-peak s-process elements, while its [Eu/$α$] and [Ba/Eu] ratios show that Pal 1's contributions from the r-process must have differed in some way from normal Galactic stars. Therefore, Pal 1 is chemically unusual, as well in its other properties. Pal 1 shares some of its unusual abundance characteristics with the young clusters associated with the Sagittarius dwarf galaxy remnant and the intermediate-age LMC clusters, and could be chemically associated with the Canis Majoris overdensity; however it does not seem to be similar to the Monoceros/Galactic Anticenter Stellar Stream.

description: The 2008 optical transient in NGC 300 is one of a growing class of intermediate-luminosity transients that brighten several orders of magnitude from a previously optically obscured state. The origin of their eruptions is not understood. Our multi-wavelength photometry and spectroscopy from maximum light to more than a year later provide a record of its post-eruption behavior. We describe its changing spectral-energy distribution, the evolution of its absorption- and emission line-spectrum, the development ofa bipolar outflow, and the rapid transition from a dense wind to an optically thin ionized wind. In addition to strong, narrow hydrogen lines, the F-type absorption-line spectrum of the transient is characterized by strong Ca II and [Ca II] emission. The very broad wings of the Ca II triplet and the asymmetric [Ca II] emission lines are due to strong Thomson scattering in the expanding ejecta. Post-maximum, the hydrogen and Ca II lines developed double-peaked emission profiles that we attribute to a bipolar outflow. Between approximately 60 and 100 days after maximum, the F-type absorption spectrum, formed in its dense wind, weakened and the wind became transparent to ionizing radiation. We discuss the probable evolutionary state of the transient and similar objects such as SN 2008S, and conclude thatthey were most likely post-red supergiants or post-AGB stars on a blue loop to warmer temperatures when the eruption occurred. These objects are not LBVs.

description: Segmentation of the liver from Computed Tomography (CT) volumes plays an important role during the choice of treatment strategies for liver diseases. Despite lots of attention, liver segmentation remains a challenging task due to the lack of visible edges on most boundaries of the liver coupled with high variability of both intensity patterns and anatomical appearances with all these difficulties becoming more prominent in pathological livers. To achieve a more accurate segmentation, a random walker based framework is proposed that can segment contrast-enhanced livers CT images with great accuracy and speed. Based on the location of the right lung lobe, the liver dome is automatically detected thus eliminating the need for manual initialization. The computational requirements are further minimized utilizing rib-caged area segmentation, the liver is then extracted by utilizing random walker method. The proposed method was able to achieve one of the highest accuracies reported in the literature against a mixed healthy and pathological liver dataset compared to other segmentation methods with an overlap error of 4.47 % and dice similarity coefficient of 0.94 while it showed exceptional accuracy on segmenting the pathological livers with an overlap error of 5.95 % and dice similarity coefficient of 0.91.

description: The method of correlation mapping on the full sphere is used to study the properties of the ILC map, as well as the dust and synchrotron background components. An anomalous correlation of the components with the ILC map in the main plane and in the poles of the ecliptic and equatorial coordinate systems was discovered. Apart from the bias, a dominant quadrupole contribution in the power spectrum of the mosaic correlation maps was found in the pixel correlation histogram. Various causes of the anomalous signal are discussed.

description: Im internationalen Diskurs über die Soziale Arbeit gibt es eine grundsätzliche Übereinkunft darüber, dass sich die Soziale Arbeit als Profession mit «sozialen Problemen» als ihr Gegenstand auseinandersetzt. Doch was ist unter sozialen Problemen zu verstehen? Und welche theoretischen Beschreibungs- und Erklärungsmöglichkeiten gibt es für die Phänomene, die als soziale Probleme deklariert werden? Im Theoriediskurs über soziale Probleme gibt es zwei konkurrierende Theorierichtungen, die sich als objektivistische und sozial-konstruktivistische Positionen deklarieren lassen. Als Vertreter der sozial-konstruktivistischen Position zeigt Michael Schetsche (2008) mit seinem Modell der «Problemkarriere sozialer Probleme» eine Möglichkeit auf, die Konstruktion sozialer Probleme zu analysieren. Die Systemtheorie von Niklas Luhmann bietet die Möglichkeit, Konstruktionen aus systemtheoretischer Sicht zu begründen, aufzuzeigen wie diese Konstruktionen in den sozialen Systemen passieren und welche Auswirkungen diese auf die Soziale Arbeit haben. Mit der Professionalisierung hat die Soziale Arbeit ihre Antwort auf die hohen Anforderungen gefunden, die von der Theorie und der Praxis an sie gestellt werden. Die vorliegende Bachelorarbeit soll aufzeigen, was soziale Probleme sind, wie sie konstruiert werden, welchen Einfluss die Soziale Arbeit auf diese Konstruktion hat und wie die Professionellen der sozialen Arbeit auf diese Erkenntnisse reagieren können. Dies mit dem Ziel, einen Beitrag an die Professionalisierungsdiskussion in der Sozialen Arbeit zu leisten.

description: This thesis develops and assesses new ways to study the conditional quantiles of a population using a sample of data that represents the population. All methods presented here build on a recently-proposed non-parametric approach to quantile regression that is analogous to local linear regression in the least-squares setting. A major challenge is that the raw local quantile estimates are cumbersome to interpret and gain insight from directly. Aiming to overcome this challenge, there are four main contributions herein. First, we demonstrate how a low-rank additive regression analysis can produce insight into a collection of local nonparametric quantile estimates. The low rank structure regularizes the noisy quantile estimates and facilitates interpretation of the findings. Second, we show how a multivariate dimension reduction approach provides a different type of insight into a collection of estimated conditional quantile functions. The third contribution of the thesis leverages the combination of nonparametric quantile estimation and low-rank regression in the context of mediation analysis. We show that this produces a novel quantile-based approach to mediation analysis that expresses direct and indirect effects in a concise and interpretable way. The final methodological contribution of the thesis is a framework for moment-based estimation of conditional covariance functions for stochastic processes. Throughout the thesis, we motivate our work through analyses looking at the proximal and distal factors predicting human blood pressure.
Travel time estimation in urban areas using neighbour links data

Publisher: name: University of British Columbia

description: Travel time is a simple and robust network performance measure that is perceived and well understood by the public and politicians. However, travel time data collection can be costly especially if the analysis area is extensive. This thesis proposes a solution to the problem of limited network sensor coverage caused by insufficient sample size of probe vehicles or inadequate numbers of fixed sensors. The approach makes use of travel time correlation between nearby (neighbour) links to estimate travel times on links with no data using neighbour links travel time data. A framework is proposed that estimates link travel times using available data from neighbouring links. The proposed framework was validated using real-life data from the City of Vancouver, British Columbia. The travel time estimation accuracy was found comparable to the existing literature. The concept of neighbour links travel time estimation was extended and applied at a corridor level. Regression and Non-Parametric (NP) models were developed to estimate travel times of one corridor using data from another corridor. To analyze the impact of the probes’ sample size on the accuracy of the proposed methodology, a case study was undertaken using a VISSIM microsimulation model of downtown Vancouver. The simulation model was calibrated and validated using field traffic volumes and travel time data. The methodology provided reasonable estimation accuracy even using small probe samples. The use of bus travel time data to estimate automobile travel times of neighbour links was explored. The results showed that bus probes data on neighbour links can be useful for estimating link travel times in the absence of vehicle probes. The fusion of vehicle and bus probes data was analyzed. Using transit data for neighbour links travel time estimation was shown to improve the accuracy of estimation at low market penetration levels of passenger probes. However, the significance of transit probe data diminishes with the increase of market penetration level of probe vehicles. Overall, the results of this thesis demonstrate the feasibility of using neighbour links data as an additional source of information that might not have been extensively explored.

description: In vorliegender Bachelorarbeit „Kritische Soziale Arbeit und ihr Gegenstand – Eine kritische Auseinandersetzung“ beschreiben die Autorin Karin Vifian und der Autor Bruno Stalder die Perspektive kritischer Sozialer Arbeit in Theorie und Praxis. Die kritische Soziale Arbeit, deren wichtigste Bezugsgrössen die Kritische Theorie und der Poststrukturalismus sind, zeichnet sich insbesondere durch eine reflexive Grundhaltung über die eigene Verstrickung im System aus und macht sich die Aufklärung über professionsbezogene Missstände zur Aufgabe. Selbstdeklariertes Ziel der kritischen Sozialen Arbeit ist es, durch die Bestimmung eines möglichst konsensfähigen Gegenstandes Sozialer Arbeit das disziplinäre und professionsbezogene Selbstverständnis zu stärken und sich der Deutungshoheit von Politik, Bürokratie und Medien weitgehend zu entziehen. Die kritische Soziale Arbeit bringt selber einen Vorschlag ins Feld, indem sie bestimmt, dass es in der Sozialen Arbeit um Prozesse und Auswirkungen sozialer Ausschliessung gehen muss. Dieser Vorschlag wird in vorliegender Bachelorarbeit geprüft. Um ein differenziertes Bild über die Gegenstandsbestimmung der sozialen Ausschliessung zu erhalten, wird sie aus verschiedenen theoretischen Perspektiven diskutiert und durch unseren Standpunkt erweitert. Herbeigezogen werden dabei drei verschiedene Theorien: die Lebensweltorientierung nach Hans Thiersch, den Systemismus nach Silvia Staub-Bernasconi und den Kritischen Rationalismus nach Lutz Rössner. Abschliessend kann festgehalten werden, dass der kritischen Sozialen Arbeit mit ihrem vorgeschlagenen Gegenstand ein wichtiger Beitrag gelingt, sie ihrem Ziel nach Konsensfähigkeit jedoch noch nicht gerecht wird

Vibrational exciton-mediated quantum state transfert: a simple model

description: A communication protocol is proposed in which quantum state transfer is mediated by a vibrational exciton. We consider two distant molecular groups grafted on the sides of a lattice. These groups behave as two quantum computers where the information in encoded and received. The lattice plays the role of a communication channel along which the exciton propagates and interacts with a phonon bath. Special attention is paid for describing the system involving an exciton dressed by a single phonon mode. The Hamiltonian is thus solved exactly so that the relevance of the perturbation theory is checked. Within the nonadiabatic weak-coupling limit, it is shown that the system supports three quasi-degenerate states that define the relevant paths followed by the exciton to tunnel between the computers. When the model parameters are judiciously chosen, constructive interferences take place between these paths. Phonon-induced decoherence is minimized and a high-fidelity quantum state transfer occurs over a broad temperature range.

description: The solution of the Langevin equation of an anisotropic fluid [Colmenares P. J; López F. and Olivares-Rivas W., Phys. Rev E. 2009, 80061123] allowed the evaluation of the position dependent perpendicular and parallel diffusion coefficients, using Molecular Dynamics data. However, the time scale of the Langevin Dynamics and Molecular Dynamics are different and an anzat for the persistence probability relaxation time was needed. Here we show how the solution for the average persistence probability obtained from the Smoluchowski-Fokker-Planck equation (SE), associated to the Langevin Dynamics, scales with the corresponding Molecular Dynamics quantity. Our SE perpendicular persistence time is evaluated in terms of simple integrals over the equilibrium local density. When properly scaled by the perpendicular diffusion coefficient, it gives a good match with that obtained from Molecular Dynamics.

description: In dieser Arbeit werden Antworten dazu gegeben, was die Herausforderungen des Themenbereichs „Abhängig von illegalen Substanzen im Alter“ für die Soziale Arbeit beinhalten. Es wird aufgezeigt, wie diesen begegnet werden kann. Einige der Überlebenden der offenen Drogenszenen wie z.B. Platzspitz und Letten haben mittlerweile das Pensionsalter erreicht. Dies konnte sicherlich zu einem Teil durch die Angebote im Rahmen der zwei Säulen „Therapie“ und „Schadensminderung“ erreicht werden. Diese zwei Säulen sind seit Anfang der Neunzigerjahre fester Bestandteil des 4-Säulen-Modells der Schweizer Drogenpolitik. Jene dieser Überlebenden, welche heute in Diaphin- und Methadonsubstitutionstherapien sind und aufgrund ihres Alters und der Begleiterscheinungen der jahrelangen Abhängigkeit nicht mehr alleine wohnfähig sind, bilden die Zielgruppe dieser Arbeit. Zusätzlich konsumieren viele der Betroffenen illegale Substanzen wie Cannabis und Kokain. Die Population der alternden Abhängigen in der Schweiz entwickelt sich anders als erwartet: Die Überlebenden werden immer älter. Die Autorinnen zeigen auf, wie es dazu gekommen ist, und welche Herausforderungen sich dadurch stellen. Entlang themenbezogener Theorien und eines Praxisbeispiels aus dem Kanton Bern wird dargestellt, welche Faktoren bei der Versorgung und Unterbringung von alternden Abhängigen illegaler Substanzen beachtet werden müssen und was die Soziale Arbeit zur adäquaten Versorgung und Unterbringung von alternden Abhängigen beitragen kann.

description: The Brownian motion of a hot nanoparticle is described by an effective Markov theory based on fluctuating hydrodynamics. Its predictions are scrutinized over a wide temperature range using large-scale molecular dynamics simulations of a hot nanoparticle in a Lennard-Jones fluid. The particle positions and momenta are found to be Boltzmann distributed according to distinct effective temperatures $T_\mathrm{HBM}$ and $T_\mathrm{k}$ . For $T_\mathrm{HBM}$ we derive a formally exact theoretical prediction and establish a generalised Einstein relation that links it to directly measurable quantities.
