text: In the context of decarbonization initiatives, the repairability and recyclability
of components have become a major concern in various industrial sectors, particularly
for resource-intensive components. The development of innovative bonding and debonding
processes that must adhere to the stringent mechanical specifications of the manufacturers
and facilitate their efficient disassembly is a major issue faced in the implementation
of a sustainable circular economy. Although adhesively bonded joints satisfy the
stringent requirements for mechanical performance, they present several challenges
during the repair and recycling process. Solvolytically debondable epoxy resin
adhesives may be employed to overcome this issue. In this study, we aim to conduct
an exploratory feasibility study on the application of such chemical debonding
mechanisms within an adhesive bond as well as to systematically analyse and evaluate
the suitability of such adhesive systems for various applications. To this end,
we employed various thermo-analytical methods and quasi-static tensile tests to
characterise the mechanical adhesive and joint properties of two solvolytically
debondable adhesive systems. Furthermore, we analysed the debondability of the
adhesive joints and evaluated their feasibility in an industrial environment.
The results indicate considerable application potential for solvolytically debondable
adhesives, along with further development steps currently required.

text: 'Diskriminierungserfahrungen können sich negativ auf die Kompetenzentwicklung
von Schülerinnen und Schülern auswirken, was wiederum Bildungsungerechtigkeit
zur Folge haben kann (Hummrich, 2023). Um solchen Dynamiken frühzeitig entgegenzuwirken
soll in der Lehrkräfteausbildung, nach den Standards der Kultusministerkonferenz
(KMK) auch der reflektierte Umgang mit Diskriminierung gefördert werden: „Die
Absolventinnen und Absolventen […] analysieren Konflikte und kennen Methoden der
konstruktiven Konfliktbearbeitung sowie des Umgangs mit Gewalt und Diskriminierung“
(KMK, 2019, S.10). Ein wichtiger Bestandteil der universitären Phase ist das Praxissemester
(PS), das in NRW ein fünfmonatiges Schulpraktikum umfasst. Obwohl sich bereits
einige Studien mit Diskriminierungserfahrungen an Schulen (z.B. Höhl, 2021; Ziemes,
2024) und in der Lehrkräfteausbildung (Fereidooni, 2015) auseinandersetzten, gibt
es bislang keine quantitative Studie, die die Perspektive von Lehramtsstudierenden
im PS systematisch einbezieht. An der Universität Paderborn wurde daher in einer
explorativen Querschnittsbefragung (N=431) erfasst, inwiefern Lehramtsstudierende
Diskriminierungssituationen im Praxissemester beobachten und wie sie ihre Kompetenzen
im Umgang mit Diskriminierung in der Schule einschätzen. In den Ergebnissen zeigt
sich, dass die Studierenden das Differenzmerkmal Migrationshintergrund mit 31%
in den beobachteten Fällen als Diskriminierungsgrund nannten. Zudem nahmen sie
wahr, dass am häufigsten die Schüler*innen untereinander abwertend über andere
Mitschüler*innen sprachen. Dies kam bei 67% der Befragten mindestens einmal im
PS vor. Bei den Studierenden selbst haben 11% mindestens einmal im PS Diskriminierung
durch Lehrkräfte erfahren und mit 14% wurden sie mindestens einmal von Schüler*innen
diskriminiert. Die Studierenden hielten sich aber überwiegend für ausreichend
kompetent im Umgang mit Diskriminierungssituationen.'

text: 'This paper examines the governance and quality control of digital curriculum
resources (DCR) for K-12 mathematics education in Germany. It focuses on approval
processes and criteria set by the 16 federal states, arguing that these have the
potential to influence the development of DCR. Using qualitative content analysis,
the study explores three research questions: which DCR require official approval,
the criteria applied for approval, and the extent to which these criteria are
mathematics-specific. Findings indicate that 10 federal states maintain official
approval systems, covering digital equivalents of printed textbooks and selected
supplemental materials. However, most DCR fall outside these regulated processes,
leaving their evaluation largely to individual schools and teachers. The study
identifies 17 categories of quality criteria, but reveals a lack of detailed,
mathematics-specific requirements. Instead, many criteria are broad references
to didactical principles and educational goals, leaving the interpretation and
application of these quality standards open-ended. Subject-specific criteria are
included but remain limited in specificity. The study underscores the need for
research-informed, mathematics-specific quality standards to guide DCR development
and approval, emphasizing their importance amidst challenges like artificial intelligence.
Policymakers are urged to adopt clearer criteria to ensure high-quality DCR to
be used in schools.'

text: Differential equations posed on quadratic matrix Lie groups arise in the context
of classical mechanics and quantum dynamical systems. Lie group numerical integrators
preserve the constants of motions defining the Lie group. Thus, they respect important
physical laws of the dynamical system, such as unitarity and energy conservation
in the context of quantum dynamical systems, for instance. In this article we
develop a high-order commutator free Lie group integrator for non-autonomous differential
equations evolving on quadratic Lie groups. Instead of matrix exponentials, which
are expensive to evaluate and need to be approximated by appropriate rational
functions in order to preserve the Lie group structure, the proposed method is
obtained as a composition of Cayley transforms which naturally respect the structure
of quadratic Lie groups while being computationally efficient to evaluate. Unlike
Cayley-Magnus methods the method is also free from nested matrix commutators.

text: Three-phase cascaded H-bridge converters (CHBs) in star configuration require
reliable current controllers to evenly charge the module DC-link capacitors. Conventionally,
a current control in dq-coordinates is utilized. At steady state, the resulting
calculated reference arm voltages are sinusoidal, have identical amplitudes and
show a phase shift of 120 degree to each other. For balanced grid inductors, the
resulting grid currents also have the same amplitude. However, own simulations
show that unbalanced grid inductors always lead to different grid current amplitudes
(4% difference in this case). As a result, the averaged charging module powers
differ and the peak DC-link capacitor voltage rises as well. In the first step,
an adaptation of an existing zero-sequence voltage injection is proposed. For
balanced grid inductors, it converges to the 3rd harmonic voltage injection which
can reduce the peak-to-peak DC-link voltage ripple up by to 50% and balances the
power between the phases. However, unbalanced grid inductors still lead to the
same unbalanced grid currents of 4%. Therefore, a new method with 4 integrators
based on linear regression is proposed to achieve sinusoidal grid currents for
unbalanced inductors. The proposed method has a similar transient dynamic as the
conventional dq control, but balances the grid currents nearly ideally. Simulation
results of a 1MW cascaded H bridge and a scaled-down prototype verify the proposed
method.
