The purpose of this paper is to examine the ways assemblaging communities work to support, hinder or disrupt literacy pedagogy in one English Language Arts (ELA) classroom. Through an expanded understanding of community based on the concept of assemblage, this paper discusses the ways in which one teacher’s critical literacies instructional practices emerged, configured and ruptured through the assemblaging communities’ that affected her enactment of critical literacies pedagogy. A focus on assemblaging communities recognizes the de/re/territorializing power of the evolving groups of bodies that produce a classroom and pedagogy in particular ways.

Drawing on observational field notes and informal exchanges, this qualitative study uses post-structural and post-human theory to examine the assemblaging communities that produced the enactment of critical literacies pedagogy in a seventh grade ELA classroom. Assemblage theory is used to analyze data to examine the assemblaging communities that de/re/territorialized in Ms T’s teaching in relation to critical literacies pedagogy. This analytical orientation allowed for a nuanced look at communities as evolving, de/re/territorializing formations that, in this study, created tensions for enacting critical literacies pedagogy.

Assemblaging communities are always producing classrooms in particular ways, demonstrating the complexities and realities of enacting literacy pedagogy. Through analysis of the data, the rupture between the assemblaging communities that produced the enactment of critical literacies pedagogy and the assemblaging communities that produced test prep (and altered critical literacies) became apparent. Ruptures like this must be attended to because enacting critical literacies pedagogy is never done neutrally and without attention to the assemblaging communities that are always de/re/territorializing pedagogy, teachers may not be equipped to respond to the unexpected ruptures as well as material realities produced from these.

Educators can use the concept of assemblaging communities for recognizing the territories that shape their literacy pedagogy. By foregrounding assemblaging communities, researchers and educators may be more appropriately equipped to consider the real-time negotiations at play when enacting critical literacies pedagogy in the classroom. Enacting critical literacies pedagogy is never done neutrally, and attention to the assemblaging communities that are always de/re/territorializing pedagogy, teachers may be more equipped to respond to the material realities that are produced through their pedagogical actions.

This study suggests assemblaging communities as a way to productively move forward a perspective on communities that foregrounds the moving bodies that produce communities differently in evolving ways and their de/re/territorializing forces that create material realities for classrooMs Assemblaging communities moves the purpose from defining a community or interpreting what it means to looking at what it does, how it functions and for this study, how assemblaging communities produced critical literacies pedagogy in one classroom.

Currently on additive manufacturing, extensive research is directed toward mitigating the main challenges associated with multi-material in fused filament fabrication which has a weak bonding strength between dissimilar materials. Low interfacial bonding strength leads to defects, anisotropy and temperature gradient in materials which negatively impact the mechanical performance of the multi-material prints. The purpose of this study was to assess the performance of different interface geometry designs in terms of the mechanical properties of the specimens.

Tensile test specimens were printed using: mono-material without a boundary interface, mono-material with the interface geometries (Face-to-face; U-shape; T-shape; Dovetail; Encapsulation; Mechanical interlocking; and Overlap) and multi-material with the interface geometries. The materials chosen with high and low compatibility were Tough polylactic acid (PLA) and TPU.

The main results of this study indicate that the interface geometries with the mechanical constriction between materials provide better structural integrity to the specimens. Moreover, in the case of the mono-material parts, the most effective interface design was the mechanical interlocking for both Tough PLA and TPU. On the other hand, in the case of multi-material specimens, the encapsulation showed the highest ultimate tensile strength, whereas the overlap and T-shape presented more robust bonding.

This study examines the mechanical performance, particularly tensile strength, strain at break, Young’s modulus and yield strength of different interface designs which were not studied in the previous studies.

The purpose of this paper is to present a procedure to design an experimental setup meant to validate an innovative approach for simulating, via computational fluid dynamics, a high-pressure gas release from a rupture (e.g. on an offshore oil and gas platform). The design is based on a series of scaling exercises, some of which are anything but trivial.

The experimental setup is composed of a wind tunnel, the instrumented scaled (1:10) mock-up of an offshore platform and a gas release system. A correct scaling approach is necessary to define the reference speed in the wind tunnel and the conditions of the gas release to maintain similarity with respect to the real-size phenomena. The scaling of the wind velocity and the scaling of the gas release were inspired by the approach proposed by Hall et al. (1997): a dimensionless group was chosen to link release parameters, wind velocity and geometric scaling factor.

The theoretical scaling approaches for each different part of the setup were applied to the design of the experiment and some criticalities were identified, such as the existence of a set of case studies with some release parameters laying outside the applicability range of the developed scaling methodology, which will be further discussed.

The resulting procedure is one of a kind because it involves a multi-scaling approach because of the different aspects of the design. Literature supports for the different scaling theories but, to the best of the authors’ knowledge, fails to provide an integrated approach that considers the combined effects of scaling.

This paper aims to identify key factors for a contextualised Systemic Risk Governance (SRG) framework and subsequently explore how systemic risks can be managed and how local institutional mechanisms can be tweaked to deal with the complex Indonesian risk landscape.

Using a case study from Palu triple-disasters in Central Sulawesi, Indonesia, the authors demonstrate how inland earthquakes in 2018 created cascading secondary hazards, namely tsunamis, liquefactions and landslides, caused unprecedented disasters for the communities and the nation. A qualitative analysis was conducted using the data collected through a long-term observation since 2002.

The authors argue that Indonesia has yet to incorporate an SRG approach in its responses to the Palu triple-disasters. Political will is required to adopt more appropriate risk governance modes that promote the systemic risk paradigm. Change needs to occur incrementally through hybrid governance arrangements ranging from formal/informal methods to self- and horizontal and vertical modes of governance deemed more realistic and feasible. The authors recommend that this be done by focusing on productive transition and local transformation.

There is growing awareness and recognition of the importance of systemic and cascading risks in disaster risk studies. However, there are still gaps between research, policy and practice. The current progress of disaster risk governance is not sufficient to achieve the Sendai Framework for Disaster Risk Reduction (2015–2030) unless there is an effective governing system in place at the local level that allow actors and institutions to simultaneously manage the interplays of multi-hazards, multi-temporal, multi-dimensions of vulnerabilities and residual risks. This paper contributes to these knowledge gaps.

Coronary artery disease (CAD) is reported as one of the most common sources of death all over the world. The presence of stenosis (plaque) in the coronary arteries results in the restriction of blood supply, leading to myocardial infarction. The current study investigates the influence of multi stenosis on hemodynamic properties in a patient-specific left coronary artery.

A three-dimensional model of the patient-specific left coronary artery was reconstructed based on computed tomography (CT) scan images using MIMICS-20 software. The diseased model of the left coronary artery was investigated, having the narrowing of 90% and 70% of area stenosis (AS) at the left anterior descending (LAD) and left circumflex (LCX), respectively.

The results indicate that the upstream region of stenosis experiences very high pressure for 90% AS during the systolic period of the cardiac cycle. The pressure drops maximum as the flow travels into the stenotic zone, and the high flow velocities were observed across the 90% AS. The higher wall shear stresses occur at the stenosis region, and it increases with the increase in the flow rate. It is found that the maximum wall shear stress across 90% AS is at the highest risk for rupture. A recirculation region immediately after the stenosis results in the further development of stenosis.

The current study provides evidence that there is a strong effect of multi-stenosis on the blood flow in the left coronary artery.
