Process Influences in the Combined Compacting and Back-Injection Process to Produce Back-Injected Self-Reinforced Composites (SRCs) – Analysis via Multiple Regression Modelling
(2021-11-21)
A new process to produce back-injected self-reinforced composites (SRCs) is presented. In contrast to other investigations on back-injection of SRCs, a process is presented which allows compacting and back injection of SRCs in one step where the SRCs are partly consolidated only via melt pressure inside the cavity. The mechanical properties of SRCs depend to a large extent on the process parameters of temperature and pressure during manufacture. These parameters are not yet known for back-injected areas. Sensors ...

Mechanical Characterization and Simulation of Wood Textile Composites (WTC) supported by Digital Image Correlation (DIC)
(2023-05-30)
Wood Textile Composites (WTC) based on willow wood fabrics and polypropylene were produced using a hot compacting process in order to open up new and innovative areas of applications for wood. Due to their attractive and variable design, the WTCs are to be used in areas with a high visual impact, for example as a facade element. In tensile and 3-point bending tests, it was shown that the mechanical properties of WTC are strongly dependent on the heterogeneous structure of the composite. Both strength and elongation ...

Functional Analysis of Src42A in embryonic epithelial morphogenesis of Drosophila melanogaster
(2023)
Src42A is one of the Src family kinases (SFKs) present in Drosophila melanogaster. In mammals there are 8 SFKs and so far, a loss of function analysis of SFKs were difficult to conduct due to their functional redundancy. In Drosophila, there are only two SFKs namely Src42A and Src64B, the former is essential for embryonic development and the latter is a non-essential gene. Since Src42A is supplied as a maternal component, the zygotic mutant were showing defects in later developmental stages, because the contribution ...

Eine Philologie der Denkformen für Indien und Europa: Sanskrit-Sūtras und Semiotik in den Cultural Studies
(2023-12)
Die anglistisch-indologische Verortung von Sanskrit-Sūtras und Semiotik in den Cultural Studies beschreibt gleichsam metonymisch die Agenda einer Vorgehensweise im Verbund von Philologie und Philosophie, verschiedene Traditionen indischen Denkens für ein zeichenphilosophisches Programm der Kulturwissenschaften zu erschließen. Dabei dient die mikrologische Rekonstruktion von Denkformen im Sinne ihrer jeweiligen semiotischen Matrix und logischen Strukturen als methodischer Bezugspunkt für die Betrachtung exemplarischer ...

Statik und Einflussfunktionen - vom modernen Standpunkt aus
(2023-01)
Einführung in die moderne rechnerbetonte Statik mit Betonung der wichtigen Rolle, die die Einflussfunktionen für die finiten Elemente bilden, mit Programmen zur Berechnung von Scheiben, Platten und ebenen Rahmen nach der Methode der finiten Elemente und Programmen zur Berechnung von Scheiben, Platten und Laplace-Problemen nach der Methode der Randelemente.

Modification of self-reinforced composites (SRCs) via film stacking process
(2022-02-25)
This work presents the mechanical behavior of self-reinforced composites (SRCs) manufactured and modified via film stacking. For modification, interleaved films made of polypropylene (PP), a thermoplastic elastomer and a polyolefin engage were combined in different ways to induce the elastic modifier into the matrix material. The content of modifier was also varied in two ways. First, the films were produced out of a single material and second out of a compound. So, the same content of modifier was implemented in two ...

Investigation of the adhesive strength in a combined compaction and back-injection process to produce back-injected self-reinforced composites (SRCs)
(2022-03-08)
This publication investigates the adhesion between an injection molded component and a self-reinforced composite (SRC) produced in a combined compaction and back-injection process to produce back-injected self-reinforced composites. To study the influence of the process, the parameters barrel temperature, time of injection, and tool temperature were varied. In addition, samples were taken at different positions along the flow path. In light of the orthotropic material behavior of SRCs, investigations were conducted ...

Patterns of Practice - Interdisciplinary Negotiation of Cultural Complexity through Practice-Based Methods in Informatics
(2022)
Following the principle of knowing through making, this thesis discusses development and application of a practice-based methodology for construction of digital artefacts within
cultural contexts. It addresses the epistemological diversity and complexity inhering within interdisciplinary projects, suggesting methodological devices able to navigate the variegated disciplinary landscape present within respective development projects. The conceptual pair complexity/complication acts as theoretical point of reference ...

Ordoliberalism Out of Order? The Fragile Constitutionality of Greek Austerity (Part Two)
(2020-06)
This is the second part of a two-part post. The first part, available here, considered the historical background of the concept of constitutional order and its relation to the ordoliberal project. Judicial independence was examined in parallel with central bank independence, with each understood as a means of insulating policy from social and democratic pressures and also as a means of enacting and maintaining fiscal discipline and market-conforming order. It also included some preliminary observations on the relation ...
