Effects of microstructure characteristics on the transverse moisture diffusivity of unidirectional composite
Authors: Wang Meng , Hang Xiaochen 
Published: May 2023

Abstract
To reveal the effects of the microstructure characteristics including fiber shape, void, fiber distribution pattern, and interphase on the transverse moisture diffusivities of unidirectional composites, the steady analysis method based on Fick’s law is adopted. The predicted numerical results are compared with the results from the analytical models to demonstrate the accuracy. From the simulation results, it is found that the increase in the oscillation amplification of non-circular fibers contributes to the orthotropy of diffusivity properties, which attributes to different barrier effects along different directions. The consideration of interphase relieves the barrier effects and the predicted diffusivity values are increased significantly. The effects of voids increase with the void volume fraction and are dependent on the voids’ location. If the fiber random distribution pattern is considered, it is found that the average values of predicted diffusivity decrease gradually with the increase in the number of oscillations.

Authors: Inturi Dakshina Murthy , Pinnam Lovaraju , Vegesna Ramachandra Raju 
Published: May 2023

Abstract
Effect of free boundary on the flow field characteristics of a single expansion nozzle has been studied experimentally and computationally. The single expansion nozzles studied in this investigation are a convergent-divergent nozzle of rectangular cross-section with convergent-divergent wall on one side and a flat wall on the opposite side, and an identical convergent-divergent ramp with its top open to atmosphere. The studies have been carried out at nozzle pressure ratios 2, 3, 4 and 5. The results show that the single expansion nozzle with wall boundary is able to deliver the flow with Mach number around 1.5, at nozzle pressure ratios of 4 and 5 even with the single expansion. The nozzle with free boundary, the wall static pressure is appreciably lower than that of nozzle with closed boundary and the exit Mach number is 1.5 for NPR 4 and 1.75 for NPR 5. That is, at the exit, the single expansion nozzle with free boundary delivers higher Mach number compared to single expansion nozzle with wall boundary for NPR 5.
Topoi and Toponyms: The Rhetoric of the City in Isa 1 and Assyrian Imperial Practices
Authors: Boyd Samuel L. 
Published: May 2023

Abstract
The influence of Assyrian ideology on First Isaiah has received extensive treatment over the past few decades. I present another possible datum to explain a rhetorical argument that unfolds in Isa 1:21–28 through the addition of the later supplement in vv. 29–31, namely the shift in Jerusalem from being labeled a »faithful city« to an »unfaithful city«. In light of the political grounding of the passage, the historical backdrop of the intermittent Assyrian practice of changing the toponyms of subjugated cities becomes more transparently important for unlocking the meaning and significance of this passage.
Le Psaume 79 et sa fonction dans la collection d’Asaf
Authors: Ramond Sophie 
Published: May 2023

Résumé
Le scénario du Ps 79 réfère à la ruine de Jérusalem et constitue un cas d’étude pour sonder la capacité des textes bibliques à parler de la souffrance. Le style anthologique et les jeux d’intertextualités plaident pour une datation tardive du psaume et suggèrent qu’il ait pour visée de concilier différentes appréciations du cours de l’histoire et du rapport de Yhwh à son peuple. Cette hypothèse trouve un appui dans le fait que le psaume est composé de trois unités, chacune ayant une perspective propre. L’ensemble de ces traits éclairent la fonction que joue ce psaume dans la collection d’Asaf.

Sports-related concussion (SRC) is a risk across all sports. New Zealand physiotherapists are more frequently in attendance at sporting events than medical doctors. The aim of this study was to determine the knowledge, attitudes, and behaviours of physiotherapists working with SRC, using a 35-item, multi-choice questionnaire. The survey was completed by 122 physiotherapists (response rate 10%). Physiotherapists were knowledgeable regarding SRC and showed positive attitudes towards correct management of the injury. Of the respondents, 98% recognised the key signs and symptoms of SRC, and 88% would refer to a medical practitioner for further assessment of SRC. Physiotherapists indicated a strong desire to be more involved in sideline management and testing, and would like to see a more multidisciplinary approach to return-to-play decision-making after SRC. Given that the knowledge, attitudes, and behaviours of New Zealand physiotherapists to SRC were very good, it is suggested that the processes in New Zealand be reviewed to enable physiotherapists to be more involved in the assessment and management of concussion.

Identity Construction of English Language Education Department Students
Authors: Mutiara Rika 
Published: May 2023

Language, identity, and community are interrelated elements. One’s identity was developed by his language use. The languages he uses depend on the community he belongs to. Constructing an identity is a lifetime process that is influenced by several factors. The present study deals with the identities of English Department students. It explores students’ identities construction. It began with an investigation of how they view their identities by analyzing family backgrounds and neighborhoods. Furthermore, it investigated how studying in the English Language Education Department contributes to identity construction as they become members of a new community. The present study applied a narrative inquiry by analyzing students’ self-reflections and conducting interviews. The students were exposed to local languages and Indonesian when they grew up. They studied English in primary school. Some of them use the local languages to talk to their families. The others only understand them but they are not able to speak the languages. The influence of environment and neighborhood makes them identify themselves as Jakartan even though their parents came from some regions in Java and Sumatera. They, moreover, do not accept all local values of their current environment. Cultural origins of the parents also play a role in students’ identity construction. The status of English Department students encourages them to use English with classmates. In addition, they use English to broaden their social relationship such as making friends with foreigners and getting exposed to the international community. It gives a contribution to their identity construction.

Improved Workflow for Production Modeling in Unconventionals Using Gaussian Mixtures and Principal Components
Authors: Sharma Akash , Sudar Selvendran 
Published: May 2023

Abstract
The current industry-wide practice of generating asset production curves is over-simplified and does not account for a lot of factors. This may lead to reporting errors and challenges in accurately and quickly quantifying well performance and asset potential. The present paper leverages Gaussian Mixture models and principal components to propose a new workflow for production modeling that incorporates all contributory factors while improving accuracy as well as speed.
We began by selecting ~2600 gas wells with at least 2 years of production history. Exploratory data analysis was conducted on the geology, petrophysics, well design and completion characteristics of the wells. Gaussian Mixtures were selected as the clustering model due to their performance and synergies with factor distributions. Singular Vector Decomposition was then used to extract the most predictive Eigenvectors (principal components) for each cluster. Cluster-level production profiles are created from these eigenvectors. Thus, this process leverages the predicting factors as well as heterogeneity in each of the well’s production profiles while creating a representative type curve.
RMSE values were calculated between the cluster-level predicted production profile and the individual well production curves. GMM-based models performed strongly with an RMSE of 0.146 for the training data and 0.746 for the test data. Additionally, type curves were calculated using more traditional means by taking monthly averages over the region as well as on an operator level. These type curves were then compared to the monthly production values for the populations they represent and the RMSE’s were calculated. The regional type curve had an RMSE of 9.3 and the company-level had an RMSE of 5.9, quantifying the marked improvement from our process. The proposed approach simplifies forecasting by providing rapid, reliable production heuristics for early-life wells without the need for complex, models that may need to be built individually from well to well.
The proposed workflow builds upon existing literature on clustering and principal components, to create a novel workflow for reliable and more comprehensive type curve generation. Additionally, it adds to the existing knowledge-based by showcasing how multiple statistical techniques can benefit our modeling work within the industry as well as provide valuable support on early life production forecasting, which is a key challenge.
