The Profiles and Artistic Experiences of Street Musicians in the Urban Spaces of Montpellier, Sète, and Paris
Authors: Chorzępa Joanna 
Published: May 2024

Abstract
The figure of the street musician has long attracted much attention among scholars working in various academic disciplines. This paper attempts to answer the question of who the street musician / artist actually is. While on a scholarship to Paul-Valéry Montpellier 3 University in 2013, I conducted a number of surveys and experiments in order better to understand what situations present-day musicians face while playing in the streets and how their social status is changing. Interviews with street performers and their audiences prove to be a valuable source of information. The paper presents the results of my own field research conducted both among street musicians and their audiences, as well as my own personal experience of performing music in public urban spaces in Montpellier, Sète, and Paris
The United States, Canada, and the Indo-Pacific Negotiations
Authors: Deblock Christian 
Published: May 2024

Abstract
The Biden administration’s strategy in the Indo-Pacific is of twofold interest. On the one hand, it breaks with the approach that the United States has always advocated since the 1980s, namely the general opening of markets through free trade agreements. And on the other hand, the economy, more than trade, is at the center of the negotiations, with security, technology, and the resilience of value chains as the main issues. Is this a turning point? After placing the Indo-Pacific Economic Framework for Prosperity (IPEF) in its historical context, the author makes seven observations about it, to conclude that the initiative currently raises more questions than it provides answers to the United States economic security.
Surgical treatment of gallstone ileus caused by cholecystoduodenal fistula – a case report
Authors: Nguyen Trong Anh , Leupolt Lars , Fischer Carolin , Schneider Eberhard 
Published: May 2024

Background:
Gallstone ileus is a rare complication of cholelithiasis caused by a bilioenteric fistula. Besides clinical examination, computer tomography (CT) scan is considered a radiological diagnostic procedure.

Case Presentation:
A 68-year-old male patient presented with epigastralgia, nausea, and emesis. The abdomen was distended and diffusely painful to palpation with peritoneal irritation. Auscultation showed raised peristaltic sounds. CT scan showed aerobilia, distension of the stomach, duodenum, and proximal jejunum, and inside it a 3.5 cm calcified round foreign body. Exploratory laparoscopy showed jejunum obstruction and chronic inflammation of the gallbladder. Lifting the small bowel through a small laparotomy was performed for gallstone removal. After recovery a delayed cholecystectomy and fistula closure followed. Hospital stays were short and complication-free.

Conclusion:
There are no guidelines for the management of gallstone ileus yet because of a limited number of reported cases. Most of the bilioenteric fistulas are located between the gallbladder and duodenum. In cases of biliocolonic fistula, causing obstruction in the colon endoscopic or conservative therapy can also be performed with a success rate of 26%. Surgical treatment is still a common procedure in emergency cases.

إن دراسة قيم الأراضي الحضرية(العقارات)، داخل المدن لم تحظ باهتمام مماثل في الدراسات الجغرافية إلى حد ما، واقتصرت المعالجات الجغرافية لهذا الموضوع على دراسته ضمن دراسة المدن العراقية كجزء من تركيب المدينة، ووظائفها الأساسية وخاصة في المدن التي يغلب عليها الطابع السكني.
لذا تعد دراسة قيم اسعار الارض الحضرية من الدراسات الجغرافية التي تستحق الاهتمام والتوجه نحوها، إذ تهدف هذه الدراسة الى ايجاد الحلول المقترحة لمواجهة مشكلة ارتفاع اسعار الاراضي والعقارات لمدينة كركوك بحدودها البلدية المتكونة من (55) حياً سكنياً والبحث عن العوامل الجغرافية المؤثرة على قيمة اسعار الأراضي فيها، اذ تم صياغة الفرضية بتداخل عدة عوامل ادت الى الارتفاع الكبير في اسعار الأراضي السكنية في العقدين الماضيين، إذ تعد المضاربات التجارية احد تلك العوامل، فضلاً على الاثار المترتبة على ذلك وفق غياب التخطيط الحكومي من حيث التجاوز على حدود التصميم الأساس والتجاوز على الأراضي الزراعية.
ولتحقيق أهداف الدراسة فقد تم استخدام عدة مناهج كان أهمها، المنهج التحليل المكاني، كما استندت الدراسة الى المنهج التطبيقي في دراسة العوامل المؤثرة في تباين قيم الأرض، وابرز المعوقات التي تواجهها في المستقبل ووضع الحلول المقترحة لحلها.
وتوصلت الدراسة إلى ان نسبة (70%) اتفقوا على قوة تأثير الدولة في سيطرتها على اسعار الاراضي والسيطرة على سماسرة العقارات ولغيابها يترك فجوة وخلل في سوق العقارات وهذا اثبات كافي على قناعة المواطنين بضرورة تدخل الدولة وفرض سيادتها الكاملة من اجل انقاذ الموقف العقاري من الانهيار، إذ ان غياب سلطة الدولة بعد عام(2003.م) والفساد الاداري وضعف دور الرقابة البلدية ومن ثم احساس المواطن بعدم وجود رقابة تلزمه بنوع الاستعمال كان لها دور كبير في تبديل استعمالات الأرض، كما يعد نمط البناء العامودي واحد من ابرز الحلول المتفق عليها من قبل المواطنين وعامل يدخل في تنمية المدينة ومشاركة الكبيرة في خفض سعر الارض وحل ازمة السكن لإمكانياتها احتواء اكبر عدد من الاسر اذ وصلت نسبة الاجابة حوالي (73%) من حجم العينة المدروسة.
وبناء على ذلك تقترح الدراسة تنظيم اسعار الاراضي والايجارات من قبل الدولة والجهات المعنية بهذا الامر ووضع حد للمضاربين بسوق العقارات، فضلاً عن اتباع سياسة اسكانية(خمسية)، لتوفير السكن الملائم للسكان وفق طرق احصائية دقيقة ومعايير تخطيطية علمية.

This paper describes the formulation and evaluation of transdermal gels for topical delivery of Curcumin. A polymer with well-defined transdermal characteristics, such as Carbopol 934, was used in this investigation. Using a variety of absorption enhancers, including Mannitol, sodium lauryl sulfate, and polyethylene glycol, carbopol, HPMC gels containing 1% curcumin were prepared using a cold technique. Due to its poor bioavailability, Curcumin has been produced in a gel form with sodium lauryl sulfate, mannitol, and polyethylene glycol as absorption enhancers. The gels underwent investigation concerning gelation temperature, pH, viscosity, drug release profile, drug content, stability studies, and kinetic analysis of drug release data. Because sodium lauryl sulfate shows a higher percentage of drug release than other absorption enhancers, it was determined to be a better enhancer of absorption.

Authors: Habibi Omid , Youssef Tarik , Naseri Hamed , Ibrahim Khalid 
Published: May 2024

In reinforced concrete (RC) structures, accurate prediction of the punching shear strength (PSS) of slab-column connections is imperative for ensuring safety. The existing equations in the literature show variability in defining parameters influencing PSS. They neglect potential variable interactions and rely on a limited dataset. This study aims to develop an accurate and reliable model to predict the PSS of slab-column connections. An extensive dataset, including 616 experimental results, was collected from earlier studies. Six robust ensemble machine learning techniques—random forest, gradient boosting, extreme gradient boosting, adaptive boosting, gradient boosting with categorical feature support, and light gradient boosting machines—are employed to predict the PSS. The findings indicate that gradient boosting stands out as the most accurate method compared to other prediction models and existing equations in the literature, achieving a coefficient of determination of 0.986. Moreover, this study utilizes techniques to explain machine learning predictions. A feature importance analysis is conducted, wherein it is observed that the reinforcement ratio and compressive strength of concrete demonstrate the highest influence on the PSS output. SHapley Additive exPlanation is conducted to represent the influence of variables on PSS. A graphical user interface for PSS prediction was developed for users’ convenience.

Published: May 2024

The utilization of nanosilica and cellulose nanocrystals (CNCs) in cement geopolymers remains challenged by intricacies and uncertainties regarding their concentration, posing difficulties in the formulation of systematic geopolymer mix designs. This study aims to formulate models based on Artificial Neural Networks (ANN) capable of forecasting the compressive strength of geopolymers through the utilization of experimentally acquired data. Nanosilica was applied at concentrations of 2%–4% and CNCs at 1%–3%. ANN was modeled using MATLAB to predict the compressive strength of the geopolymer. The results indicated an effect of nanosilica and CNCs on the compressive strength of geopolymer at 2%–4% concentration and 1%–3% CNCs. The best ANN was the GDX training function, purelin activation function, LGD and LGDM learning functions, Lr 0.1 and 0.01 at the number of epochs 3812 out of 25000 and 1774 out of 25000, resulting in the best correlation values of 0.994 and 0.959; the lowest RMSE values are 0.022 and 0.110. The results of the ANN model built based on actual data prove that the model is helpful for accurate simulation to predict the compressive strength of geopolymer cement. This study contributes novelty by optimizing the design model for Geopolymer Cements incorporating nanosilica and CNCs. Doi: 10.28991/CEJ-SP2024-010-03 Full Text: PDF
The Influence of Recycled Coarse Aggregate Content on the Properties of High-Fly-Ash Self-Compacting Concrete
Authors: Nguyen Hung Cuong 
Published: May 2024

In Vietnam, solid waste from construction activities significantly impacts environmental pollution. Recycled concrete aggregate (RCA), derived from waste concrete, can serve as a coarse aggregate in concrete production. However, compared to natural aggregates, RCA exhibits distinct characteristics, including lower strength, higher water absorption, and an increased angular and rough surface. These properties may influence concrete’s workability, compressive strength, and durability. This research investigates the influence of RCA on the properties of High-Fly-Ash Self-Compacting Concrete (SCC). The study explores various replacement levels of natural coarse aggregate with RCA (0%, 50%, 75%, and 100%), alongside a 50% volume fraction of fly ash. Key concrete properties evaluated include workability, compressive strength, flexural strength, and chloride ion permeability. The findings reveal that using 100% RCA in combination with a high fly ash content (50%) produces SCC that meets workability requirements according to EFNARC standards. However, there are trade-offs: the compressive strength decreases by 4.61%, the flexural strength decreases by 3.1%, and chloride ion permeability increases by 57.57% compared to the control sample (using natural aggregates). Notably, the chloride ion permeability of SCC using 100% RCA falls into the category of low permeability. Doi: 10.28991/CEJ-SP2024-010-04 Full Text: PDF
Numerical Analysis of Time-Dependent Strength and Stiffness in Palm Oil Fuel Ash-Stabilized Soil: Early and Long-Term Effects
Authors: Al-Dalain Nour A. W. , Ezreig Ali M. A. , Ismail Mohd A. M. 
Published: May 2024

Over the years, investigating the behavior of soft soil, stabilized using different techniques, has been recognized as a critical priority for geotechnical engineers. Numerous soil constitutive models have been utilized to simulate stabilized soil behavior, improve strength and ductility, and analyze load-deformation responses. However, further investigation is required to study stabilized soil's time-dependent strength and stiffness, especially at an early curing age. Early strength and stiffness development is crucial in engineering construction for improving building quality and efficiency and minimizing crack risk. Furthermore, estimating UCS from an early age aid in safety evaluation and ground-improvement analysis. Researchers are increasingly recognizing palm oil fuel ash (POFA) as an eco-friendly alternative to traditional soil stabilizers due to its abundant availability. This study proposes an advanced concrete constitutive model to simulate the time-dependent strength and stiffness of POFA-stabilized and cement-stabilized soil due to pozzolanic interactions. The model accurately measures strength and stiffness improvement from an early curing age to 28 days using finite element analysis (FEA) before then comparing the experimental results. Based on the experimental results, the UCS values of palm oil fuel ash-stabilized soil grew to 3.18 MPa and 3.89 MPa after seven and 28 days with an optimum content of 30% (POFA): 10% Magnesium Oxide (MgO). It exhibited a significant increase in early strength with 64.02% compared with cement-stabilized soil. For stiffness results, a slight increment of 9.26% was observed. Employing FEM, the sensitivity of the parameters to stress-strain behavior was investigated. Finally, the validity of the concrete constitutive model to predict the time-dependent strength and stiffness of stabilized soil was proved. Doi: 10.28991/CEJ-SP2024-010-05 Full Text: PDF
Unified AI-Based Predictive Models for the Ultimate Capacity of Multi-Planar Gapped KK Steel Pipe Joints
Authors: Kadry Ahmed , El-Ganzoury Eslam , Mokhtar Abdel Salaam A. , Aboul Haggag Said Y. , Ebid Ahmed 
Published: May 2024

The multi-planar steel pipe joints are widely used in communication towers, industrial structures, and offshore platforms. The current design formulas consider this joint as a uniplanar joint and account for the multi-planar effect using empirical correction factors. Recent studies deal with this multi-planar joint as a 3D joint but considering certain loading conditions. Hence, the aim of this research is to develop more general AI-based predictive models for the ultimate capacity of multi-planar gapped KK steel pipe joints, considering both symmetric and asymmetric loading conditions. Three AI techniques were applied to a database of previously published works. These techniques are “Genetic Programming” (GP), “Artificial Neural Network” (ANN), and “Evolutionary Polynomial Regression” (EPR). The prediction accuracies of the developed AI models were compared against two previously published formulas. The results indicated that the developed AI models are much more accurate than the previously published formulas. Also, the results showed that both the ANN and EPR models have almost the same level of accuracy (about 92%), but the EPR model has the advantage of presenting a closed-form equation that could be implemented either manually or using software.

Published: May 2024

The purpose of this study was to review the effectiveness of Reduced Working Hours Strategies (RWHS) such as The Four Day Week and explore Irish construction industry perception of how implementing such strategies might impact employee health, safety, well-being, recruitment, retention, and productivity. A mixed-methods research approach was used to uncover any perceptions of benefits, drawbacks and feasibility of RWHSs. The employer’s perspective was based on semi-structured interview data from market leading international construction companies. This was triangulated with survey data from the employee’s perspective to generate richer insightsResults suggested RWHSs could significantly improve working and personal lives of on-site employees. Employees were working on average above 50 hours per week and are aware of the potential benefits of RWHSs particularly with regard to health, accidents, retention and work- life balance. The research indicates that from employer perspective, the study concluded that management personnel were wary of widespread implementation of RWHSs but regarded their implementation feasible in specific aspects of the construction process such as pre-fabrication. Furthermore, they felt increased use of BIM and innovative procurement might facilitate such strategies. Exploring the use of RWHSs was generally perceived as necessary and potentially beneficial, particularly given the industry’s recruitment, retention and productivity issues.

This research presents a profile of the sought-after competencies of construction managers in leading United Kingdom (UK) construction organizations. In doing so, the work contextualizes the construction organizations influence in terms of revenue and employability; conducts a textual analysis of interpersonal and technical competencies from construction manager job advertisements to ascertain the specific competencies desired by construction organizations; and provides a ranking of said competencies to establish a competencies hierarchy in order to inform curriculum development processes.Research findings demonstrate that interpersonal competencies have around 70% importance within the role of construction manager. There exists; however, a prevalent vernacular imprecision within the job advertisements about the specific technical competencies for the role exist. Specifically, the lack of digital-esque skills is profound. Thus, a misalignment is present between current educational provision and industry practice regarding the core foundational competencies required of the construction management profession.This research constitutes an attempt to conduct a textual analysis of descriptive metadata contained within construction manager job advertisements from leading UK construction organizations. Emergent findings revealed specific competencies that are essential to the core of the modern construction manager’s role.
