description: Charged particle and gamma decays in 24Mg* are investigated for excitation energies where quasimolecular resonances appear in 12C+12C collisions. Various theoretical predictions for the occurence of superdeformed and hyperdeformed bands associated with resonance structures with low spin are discussed within the measured 24Mg* excitation energy region. The inverse kinematics reaction 24Mg+12C is studied at E_lab(24Mg) = 130 MeV, an energy which enables the population of 24Mg states decaying into 12C+12C resonant break-up states. Exclusive data were collected with the Binary Reaction Spectrometer in coincidence with EUROBALL IV installed at the VIVITRON Tandem facility at Strasbourg. Specific structures with large deformation were selectively populated in binary reactions and their associated gamma decays studied. Coincident events associated with inelastic and alpha-transfer channels have been selected by choosing the excitation energy or the entry point via the two-body Q-values. The analysis of the binary reaction channels is presented with a particular emphasis on 24Mg-gamma, 20Ne-gamma and 16O-gamma coincidences. New information (spin and branching ratios) is deduced on high-energy states in 24Mg and 16O, respectively.

description: On-axis swap-out injection is a promising injection scheme for the diraction-limited storage rings with small dynamic apertures. However, some previous studies have shown that the initial mismatch in the longitudinal phase space may lead to transverse collective instability before approaching the equilibrium state, especially in the high bunch charge situation. We present our study of mitigating the collective eects in the transient process after injecting beam into storage rings by implementing RF modulation technique in booster. Both bunch lengthening and the increase of energy spread could be observed in the extracted bunch from booster. The reduction of particle loss in the transient process after the swap-out injection is demonstrated via simulations.

description: We perform a direct test of the gauge-gravity duality associated with the system of N D0-branes in type IIA superstring theory at finite temperature. Based on the fact that higher derivative corrections to the type IIA supergravity action start at the order of α'^3, we derive the internal energy in expansion around infinite 't Hooft coupling up to the subleading term with one unknown coefficient. The power of the subleading term is shown to be nicely reproduced by the Monte Carlo data obtained nonperturbatively on the gauge theory side at finite but large effective (dimensionless) 't Hooft coupling constant. This suggests, in particular, that the open strings attached to the D0-branes provide the microscopic origin of the black hole thermodynamics of the dual geometry including α' corrections. The coefficient of the subleading term extracted from the fit to the Monte Carlo data provides a prediction for the gravity side, which can be checked once the complete form of the O(α'^3) corrections to the supergravity action is obtained.

description: ISIS is the pulsed spallation neutron and muon source at the Rutherford Appleton Laboratory in the UK. Operation centres on a rapid cycling proton synchrotron (RCS) which accelerates 3 × 1013 protons per pulse from 70 MeV to 800 MeV at 50 Hz, delivering a mean beam power of 0.2 MW. Research and development at ISIS are focused on key aspects of high intensity operation with a view to increasing beam intensity on target, understanding loss mechanisms and identifying viable upgrade routes. At present, the main limitation on beam intensity at ISIS is beam loss associated with the head-tail instability. This paper presents new measurements of the head-tail instability in both RCS and storage ring modes whilst highlighting the differences between these and theoretical predictions. Macro-particle simulations of the instability are shown in comparison with experimental data. Finally, preliminary tests of an active transverse feedback system to damp the instability are also presented.

description: The CERN FCC-ee top-up booster synchrotron will accelerate electrons and positrons from an injection energy of 20 GeV up to an extraction energy between 45.6 GeV and 182.5 GeV depending on the operation mode. These accelerated beams will be used for the initial filling of the high-luminosity FCC-ee collider and for keeping constant the beam current over time using continuous top-up injection. Due to the high-intensities of the circulating beams, collective eects may represent a limitation in the top-up booster. In this work we present a first evaluation of the impedance model and the eects on beam dynamics. Methods to mitigate possible instabilities will be also discussed.

The influence of plane of nutrition on the early growth of the Holstein calf
Creators: name: Leche, Terence Frederick
Publisher: name: University of British Columbia
Year: 2011

description: The influence of the nutritive plane on the early growth of the Holstein calf has been investigated. Particular attention has been given to near-maximal growth rates, and to the ability of calves to exhibit compensatory growth after nutrient restriction is removed. A whole milk feeding standard, intended to allow maximum consumption, was established and used as the plane of nutrition for a group of high-plane calves. A second group of calves was fed milk at a lower plane for a period, before being realimentated to the same high plane that their contemporaries had received. Metabolic rate measurements were made on all calves at regular intervals. The animals of both groups were slaughtered at a body weight of 113 kgm (250 lb) and various measurements were taken from the dissected carcasses. The high-plane feeding standard proved to be quite satisfactory and permitted weight gains from 1.09 to 1.34 kgm/ day for the calves reared continuously on this plane. Highly reproducible rates of gain were displayed by the low-plane calves, both during the periods of restriction and realimentation. The growth rates of the low-plane calves in the latter period exceeded those of the high-plane animals, being from 1.45 to 1.6l kgm/day. The possible reasons for this increased growth capability are discussed in relation to the studies of other workers on compensatory growth. Nutrient restriction depressed the metabolic rates of low-plane calves below those exhibited by their high-plane partners of equal weight. Upon realimentation, the metabolic rates of the previously-restricted calves rose quite rapidly to levels commensurate with the heat losses of the high-plane animals. The carcass dissection studies did not reveal extensive modifications in body composition that could be attributed to the treatments. The growth of certain visceral organs was retarded or accelerated by the nutritive planes imposed, but the musculature and skeleton were apparently unaffected by the pattern of growth. The yield of edible meat was essentially the same for both groups of animals, despite a lower consumption of milk by the calves whose growth had been interrupted. A model, for comparison of the relative efficiencies of restricted and unrestricted meat-producing animals, is suggested.

description: Electron lenses provide an incoherent betatron tune spread for Landau damping of transverse coherent beam instabilities. We investigated the eect of the transverse electron beam size and shape for Landau damping with an electron lens. Another point of interests is Landau damping provided by a pulsed electron lens with homogeneous transverse beam profile. This type of electron lens is developed for space-charge compensation in SIS18.

description: In modern particle accelerators, satisfying the desired beam properties (high currents, high luminosities, etc) increasingly implies limiting the total beam coupling impedance, which depends on the machine and the parame- ters of the circulating beams. A number of dierent reduction techniques have been proposed during the years depending on the specific applications, ranging from higher order modes (HOM) damping to solutions entailing high electrical- conductivity coatings of the pipe. This paper investigates the use of metamaterial-based absorbers for sensibly reducing or nearly cancelling the HOM contribution to the impedance. We design and fabricate sub-wavelength two-dimensional metallic resonant structures based on the split ring resonator (SRR) geometry that can be employed as mode dampers in accelerating structures. Experimental results inside a pillbox cavity well agree with full wave electromagnetic simulations. In this work we present the first results on a SRR geometry tailored for LHC collimators. We showed how metamate- rials can be a valid alternative for impedance mitigation in experimental devices commonly operating along a particle beam line.

TMCI, why is the horizontal plane so different from the vertical one?
Creators: name: Günzel, T.
Publisher: name: CERN Yellow Reports: Conference Proceedings
Year: 2020

description: Based on the recent work of R. Lindberg on transverse collective instabilities it was observed that if the ratio of quadrupolar to dipolar impedance ρ is equal to -1, there is no TMC-instability. This relationship is actually fulfilled by resistive wall (RW)-impedance on the horizontal plane in case of a flat vacuum chamber. HEADTAIL simulations were carried out to check if this observation can be con- firmed. Additionally the eect of radial modes on the TMC- instability was studied.

description: Many social insects display age polyethism: young workers stay inside the nest, and only older workers forage. This behavioural transition is accompanied by genetic and physiological changes, but the mechanistic origin of it remains unclear. To investigate if the mechanical demands of foraging effectively prevent young workers from partaking, we studied the biomechanical development of the bite apparatus in Atta vollenweideri leaf-cutter ants. Fully-matured foragers generate peak in-vivo bite forces of around 100 mN, more than one order of magnitude in excess of those measured for freshly eclosed callows of the same size. This change in bite force was accompanied by a sixfold increase in the volume of the mandible closer muscle, and by a substantial increase of the flexural rigidity of the head capsule, driven by a significant increase in both average thickness and indentation modulus of the head capsule cuticle. Consequently, callows lack the muscle force capacity required for leaf-cutting, and their head capsule is so compliant that large muscle forces may cause damaging deformations. On the basis of these results, we speculate that continued biomechanical development post eclosion may be a key factor underlying age polyethism, wherever foraging is associated with mechanical demands on the musculoskeletal system.

The most interesting single result is probably a simpler proof of a key step in the proof of the Green-Tao theorem, but several other applications of the method are given. A similarly simplified proof of the Green-Tao transference principle was obtained independently (and expressed in a rather different language) by Reingold, Trevisan, Tulsiani and Vadhan.

description: We investigate whether having a unique equilibrium (or a given number of equilibria) is robust to perturbation of the payoffs, both for Nash equilibrium and correlated equilibrium. We show that the set of n-player finite games with a unique correlated equilibrium is open, while this is not true of Nash equilibrium for n>2. The crucial lemma is that a unique correlated equilibrium is a quasi-strict Nash equilibrium. Related results are studied. For instance, we show that generic two-person zero-sum games have a unique correlated equilibrium and that, while the set of symmetric bimatrix games with a unique symmetric Nash equilibrium is not open, the set of symmetric bimatrix games with a unique and quasi-strict symmetric Nash equilibrium is.

This ICFA Mini-Workshop on “Mitigation of Coherent Beam Instabilities in Particle Accelerators" (MCBI2019) focused on all the mitigation methods for all the coherent beam instabilities, reviewing in detail the theories (and underlying assumptions), simulations and measurements on one hand, but on the other hand trying to compare the different mitigation methods (e.g. with respect to other effects such as beam lifetime) to provide the simplest and more robust solutions for the day-to-day operation of the machines.

description: It has been recently proposed that neutrino mass could originate from Yukawa interactions of leptons with new colored particles. This raises the interesting possibility of testing mass generation through copious production of those particles at hadron colliders. A realistic assessment of it however should take into account how large those interactions could be from available precision results. In this work we make a systematic analysis to the flavor structure in Yukawa couplings, provide a convenient parametrization to it, and investigate the rare radiative and pure leptonic decays of the muon and tau leptons. For general values of parameters the muon decays set stringent constraints on the couplings, and all rare tau decays are far below the current experimental sensitivity. However, there is room in parameter space in which the muon decays could be significantly suppressed by destructive interference between colored particles without generically reducing the couplings themselves. This is also the region of parameters that is relevant to collider physics. We show that for this part of parameter space some tau decays can reach or are close to the current level of precision.

description: Several studies have examined the prognostic significance of IDH1/2 mutation, 1p/19q codeletion and MGMT promoter methylation in lower-grade gliomas but most of these used the 2007 fourth edition of the WHO classification. We evaluate prognostic significance of these indicators in the 2016 WHO updated fourth edition of CNS tumor classification. A total of 180 intracranial glioma patients diagnosed according WHO 2016 edition between December 2016 and December 2018 Jinling Hospital (Nanjing, China) were reviewed retrospectively. We performed survival analysis on 109 patients with complete molecular pathology and follow-up data. Histologically, 52 were diagnosed as astrocytoma (WHO grade II and III), 17 as oligodendrogliomas (WHO grade II and III) and 40 as GBMs. At last follow-up, 50.5% patients had experienced tumor progression and 34.9% had died. Among grade II and III cases 36.2% experienced tumor progression and 27.5% died. In univariate Kaplan–Meier analysis, multifocal tumor, EGFR mutation or amplification, PIK3CA mutation and IDHwt/TERTpwt group were associated with shorter PFS (p < 0.001, p = 0.003, p = 0.005, p < 0.001, respectively) and OS (p = 0.010, p = 0.020, p = 0.018, p < 0.001, respectively) as were older age (≥55 years), multifocal tumor, IDH1/2 wild type, 1p/19q non-codeletion and negative methylation in the MGMT promoter region. A Cox proportional hazards model was created demonstrating that single tumor (HR = 0.180, p = 0.04), MGMTp methylation (HR = 0.095, p = 0.003) and chemoradiotherapy (HR = 0.006, p = 0.002) were independent prognostic factors for OS. Beyond histological classification as well as IDH1/2 mutation, 1p/19q codeletion status, we could incorporate IDH1/2mt combined with TERTpmt, EGFR mutation or amplification and PIK3CA mutation into the diagnostic criteria for DLGGs to supplement WHO 2016 pathological criteria.

description: The problem we concentrate on is as follows: given (1) a convex compact set $X$ in ${\mathbb{R}}^n$, an affine mapping $x\mapsto A(x)$, a parametric family $\{p_μ(\cdot)\}$ of probability densities and (2) $N$ i.i.d. observations of the random variable $ω$, distributed with the density $p_{A(x)}(\cdot)$ for some (unknown) $x\in X$, estimate the value $g^Tx$ of a given linear form at $x$. For several families $\{p_μ(\cdot)\}$ with no additional assumptions on $X$ and $A$, we develop computationally efficient estimation routines which are minimax optimal, within an absolute constant factor. We then apply these routines to recovering $x$ itself in the Euclidean norm.

Der Lernkontext wird vor allem in Bezug auf die kulturelle Angemessenheit von Unterrichtsverfahren untersucht. Im Bezug auf den Lernprozess werden drei Praxisfelder hervorgehoben, denen die Thematisierung von Verstehen, die Bedeutung nicht-kognitiven Lernens und direkten interkulturellen Kontakts gemeinsam ist. Was das Lernziel angeht, so gibt es verschiedene Kompetenzbeschreibungen, die in der Regel aus einer Kombination von handlungsorientierten, kognitiven und affektiven Komponenten bestehen. Drei dieser Konzeptionen werden kurz vorgestellt. Abschließend diskutiere ich noch, welche Begriffe geeignet scheinen, das Unterrichtsziel Interkulturalität am günstigsten zu beschreiben.

description: Studying outliers from the bimodal distribution of galaxies in the color-mass space, such as morphological early-type galaxies residing in the blue cloud, can help to better understand the physical mechanisms that lead galaxy migrations in this space. In this paper we study the evolution of the properties of 210 M*/Msol>10^10 blue E/S0s between z~1.4 and z~0.2 in the COSMOS field with confirmed spectroscopic redshifts from the zCOSMOS 10k release. We first observe that the threshold mass, defined at z=0 in previous studies as the mass below which the population of blue early-type galaxies starts to be abundant relative to passive E/S0s, evolves from log(M*/Msol)~10.1 at z~0.3 to log(M*/Msol)~10.9 at z~1. Second, there seems to be a turn-over mass in the nature of blue E/S0 galaxies. Above log(M*/Msol)~10.8 blue E/S0 resemble to merger remnants probably migrating to the red-sequence in a time-scale of ~3 Gyr. Below this mass, they seem to be closer to normal late-type galaxies as if they were the result of minor mergers which triggered the central star-formation and built a central bulge component or were (re)building a disk from the surrounding gas, suggesting that they are moving back or staying in the blue-cloud. This turn-over mass does not seem to evolve significantly from z~1 in contrast with the threshold mass and therefore does not seem to be linked with the relative abundance of blue E/S0s.

Coping with racial microaggressions: the moderating effects of parenting style
Creators: name: Talley, Quintin
Publisher: name: Maryland Shared Open Access Repository
Year: 2014

description: The purpose of this study was to examine the relationship between race-related stress and coping strategies, and to examine the influence that parenting style has on coping with race-related stress specifically elicited by racial microaggressions. Literature suggests that parenting style influences various aspects of behavior throughout one's lifetime, including coping tendencies. However, there is a dearth of research which examines how parenting styles (Baumrind, 1966, 1971; Maccoby & Martin, 1983) moderate coping strategies that racial/ethnic minorities use to cope with race-related stress induced by racial microaggressions, a contemporary, prevalent, and chronic form of racism. This study addresses this gap in research by studying how parenting style effects coping strategies used by adults (N=263) for race-related stress related to racial microaggressions. The study consisted of self-report data collected from an online survey. Most participants were undergraduate students recruited through a University research pool. Regression analyses indicated that authoritative parenting moderated the relationship between race-related stress and coping with discrimination. Implications of these findings and directions for future research are discussed.

description: Das Großereignis 2006, die Fußball-WM in Deutschland unter dem Motto "Die Welt zu Gast bei Freunden", wirft seine Schatten bereits seit geraumer Zeit voraus, leider überwiegend durch Negativschlagzeilen etwa aufgrund des Vergabeverfahrens der Eintrittskarten, der Absage der Eröffnungsfeier oder der Bedenken bei der Stadionsicherheit. Nichtsdestotrotz scheint das Interesse an dem globalen ‚Mega-Event' ungebrochen zu sein, und neben Firmen aus dem Merchandising-Bereich will nun auch der Langenscheidt-Verlag die Gunst der Stunde für eigene Verkaufszwecke nutzen und ist gerade noch rechtzeitig mit dem Unterrichtspaket Deutschlernen mit Kick. Fußball für Fans und Deutschlernende auf dem DaF-Lehrbuchmarkt erschienen. Ob sich dieses thematisch singuläre Unterrichtswerk nachhaltig als DaF-Lehrbuch etablieren kann oder ob sich dessen Einsatz auf den recht überschaubaren Zeitraum von kurz vor bis kurz nach der Fußball-WM beschränken wird, das will die vorliegende Rezension u.a. zu klären versuchen.

description: In October 2020, the authors accepted an invitation to participate in an experimental collaboration observing an equitable, global, and inclusive process. Inspired by an Inclusive Classroom webinar1 at the University of Illinois at Urbana-Champaign and the shared Decolonizing Checklist,2 the authors considered our tasks: 1) to develop a checklist or brief guide that is international in scope to help librarians worldwide develop their own or other educators’ instructional materials, that is antiracist or inclusive, and 2) to publish the checklist/guide and a reflective essay of the process. After reviewing the original checklist and attempting to construct our own, we realized that the task was more nuanced than originally thought, especially as we considered the central roles of libraries within the academy, and what would drive our construction of this checklist. We deliberated on matters of terminology, specific areas of focus for librarians and faculty, our personal viewpoints, and concluded that the conversation needed voices that represented other and wider perspectives. In the spirit of inclusiveness, we offer our conversation as a spark to further conversations towards a more fulsome and robust outcome.

description: Die beiden Anglisten Klaus Stierstorfer (Düsseldorf) und Laurenz Volkmann (Jena) legen in dem hier zu besprechenden Werk Kulturwissenschaft Interdisziplinär "eine Reihe von disziplingebundenen Versuchen zur Erläuterung von Kulturwissenschaft" (S. 10) vor. Sie verbreitern damit ganz erheblich ein Feld, welches Böhme / Matussek / Müller im Jahr 2000 im wesentlichen in germanistischer Perspektive beleuchtet/bearbeitet hatten (Böhme / Matussek / Müller: Orientierung Kulturwissenschaft. Was sie kann, was sie will. Hamburg 2000). Stierstorfer weist in seinem einleitenden Beitrag jegliche Vermessenheit von sich, wenn er klarstellt, keine "Kulturwissenschaft tout court" (S. 10), sprich keine Suprawissenschaft mit Namen Kulturwissenschaft anzusteuern. Gleichwohl trägt der Band den Titel Kulturwissenschaft, und die meisten Beiträge operieren mit diesem Begriff; lediglich Stierstorfer in seinem Einleitungsbeitrag und Mittag in ihrem Text zu Gender studies führen den Begriff Kulturwissenschaften im Titel, in Stierstorfers Einleitung kann aus der Verwendung von Kulturwissenschaft(en) (S. 9) gefolgert werden, daß für ihn beide Begriffe inhaltlich austauschbar/ gleichzusetzen sind. Für viele sind sie das aber gerade nicht: Kulturwissenschaften steht als Begriff für eine ganze Reihe von etablierten Wissenschaften, die sich in unterschiedlicher Perspektivierung und mit sehr verschiedenen Methoden auch mit dem Gegenstand Kultur befassen, Kulturwissenschaft hingegen steht (noch?) für eine übergeordnete Suprawissenschaft, die bisweilen mit einem Alleinvertretungsanspruch hinsichtlich Kultur auftritt. Ziehen wir diesen Kontext und darüber hinaus die Tatsache in Betracht, daß das Anliegen der Herausgeber nachweislich in dem Bestreben liegt, die Leistungen verschiedener Kulturwissenschaften im Blick zu behalten und zu fokussieren, bleibt hinsichtlich des Buchtitels anzumerken, daß er treffender Kulturwissenschaften integrativ heißen würde. Genau das nämlich bietet dieses empfehlenswerte Studienbuch: es führt die unterschiedlichsten disziplingebundenen kulturwissenschaftlich orientierten Forschungszweige vor Augen, statt einer nebulösen Kulturwissenschaft das Wort zu reden.
About the dynamics and thermodynamics of trapped ions

description: This tutorial introduces the dynamics of charged particles in a radiofrequency trap in a very general manner to point out the differences between the dynamics in a quadrupole and in a multipole trap. When dense samples are trapped, the dynamics is modified by the Coulomb repulsion between ions. To take into account this repulsion, we propose to use a method, originally developed for particles in Penning trap, that model the ion cloud as a cold fluid. This method can not reproduce the organisation of cold clouds as crystals but it allows one to scale the size of large samples with the trapping parameters and the number of ions trapped, for different linear geometries of trap.

description: We investigate the causes of the different shape of the $K$-band number counts when compared to other bands, analyzing in detail the presence of a change in the slope around $K\sim17.5$. We present a near-infrared imaging survey, conducted at the 3.5m telescope of the Calar Alto Spanish-German Astronomical Center (CAHA), covering two separated fields centered on the HFDN and the Groth field, with a total combined area of $\sim0.27$deg$^{2}$ to a depth of $K\sim19$ ($3σ$,Vega). We derive luminosity functions from the observed $K$-band in the redshift range [0.25-1.25], that are combined with data from the references in multiple bands and redshifts, to build up the $K$-band number count distribution. We find that the overall shape of the number counts can be grouped into three regimes: the classic Euclidean slope regime ($d\log N/dm\sim0.6$) at bright magnitudes; a transition regime at intermediate magnitudes, dominated by $M^{\ast}$ galaxies at the redshift that maximizes the product $ϕ^{\ast}\frac{dV_{c}}{dΩ}$; and an $α$ dominated regime at faint magnitudes, where the slope asymptotically approaches -0.4($α$+1) controlled by post-$M^{\ast}$ galaxies. The slope of the $K$-band number counts presents an averaged decrement of $\sim50%$ in the range $15.5

Quasi invariant modified Sobolev norms for semi linear reversible PDEs

description: We consider a general class of infinite dimensional reversible differential systems. Assuming a non resonance condition on the linear frequencies, we construct for such systems almost invariant pseudo norms that are closed to Sobolev-like norms. This allows us to prove that if the Sobolev norm of index $s$ of the initial data $z_0$ is sufficiently small (of order $ε$) then the Sobolev norm of the solution is bounded by $2ε$ during very long time (of order $ε^{-r}$ with $r$ arbitrary). It turns out that this theorem applies to a large class of reversible semi linear PDEs including the non linear Schrödinger equation on the d-dimensional torus. We also apply our method to a system of coupled NLS equations which is reversible but not Hamiltonian. We also notice that for the same class of reversible systems we can prove a Birkhoff normal form theorem that in turn implies the same bounds on the Sobolev norms. Nevertheless the technics that we use to prove the existence of quasi invariant pseudo norms is much more simple and direct.

description: Our approach is educational, targeting mainly elementary, middle and high school teachers and members of astronomy communities as well, who wish to expand their knowledge and skills through the Project Based Learning methodology, using the robotic telescope network of Las Cumbres Observatory as well as free use resources during our workshops. Participants provide input from their experience, actively participate in the observations programming and analyze the obtained results, which empowers them during the workshop by applying the knowledge acquired. This motivates them to apply the knowledge acquired in their classrooms, showing their students that doing science has a deep relationship with their personal learning.

description: Die Veröffentlichung einer Einführung zum Thema Fremdspracherwerb, Fremdsprachendidaktik war seit Jahren wünschenswert, und es ist erfreulich, dass nun ein Band zu diesem Thema vorliegt. Roche gliedert in acht Kapiteln das Thema in die Bereiche 'Lerntheorien und Fremdspracherwerb'; 'Lernervariablen'; 'Lernuniversalien'; 'Fremdsprachenerwerb'; 'Sprache'; 'Lehr- und Lernziele'; 'Interkulturelle Sprachdidaktik'; 'Medien'. Darüber hinaus ist ein Anhang mit Lösungen zu den Übungsaufgaben und einem Register zu den wichtigsten Begriffen vorhanden. In jedem Kapitel gibt Roche eine kurze Einführung. Anschließend werden mit Hilfe von Grafiken die wichtigsten Begriffe erläutert und Beispiele gegeben. Am Ende jedes Kapitels sind noch Übungsaufgaben und im Schnitt zwischen zehn und fünfzehn Angaben zur weiterführenden Literatur vorhanden. Diese Art der Progression, welche dem Prinzip von der Theorie zur Praxis folgt, ist gelungen, obwohl es manchmal an Tiefe fehlt, die andererseits von einer Einführung auch nicht unbedingt erwartet werden kann.
