Published: January 2024

There are several constructions in Aceh Tengah Regency that have experienced deviations between the initial planning and the result in terms of time, cost and quality. There was many obstacles which influence the performance of a project which therefore, inevitably, become the cause of the delays in the process of completing a project. This study was aimed at determining the risk factors that affect the time performance of project development in Aceh Tengah. This study was conducted by analysing perception data obtained from questionnaires from contractor respondents. The data of this study derived from primary and secondary data collection. The primary data were collected from questionnaires which were distributed to 57 respondents who were qualified as K1, K2, K3 and M1 contractors in Aceh Tengah. While the secondary data were in the form of supporting theories taken from books, journals and other literature. The method used in analysing the data were the Severity Index which was used to determined the level of probability and risk impact followed by a risk matrix which used to measure the level of the risks. The results of this study showed that there were 4 dominant risk factors and 20 description of the risk factors which belonged to the medium and high categories, namely 2 factors with medium categories are in the field of the design factor and construction factor. As well as 2 factors with high categories found in the financial factors section. Where these four factors have an impact on project time, namely the occurrence of delays or even the project can be stopped. This will increase costs so as to create a loss for the contractor.@font-face {font-family:"Cambria Math"; panose-1:2 4 5 3 5 4 6 3 2 4; mso-font-charset:0; mso-generic-font-family:auto; mso-font-pitch:variable; mso-font-signature:-536870145 1107305727 0 0 415 0;}p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-unhide:no; mso-style-qformat:yes; mso-style-parent:""; margin:0cm; margin-bottom:.0001pt; text-align:justify; mso-pagination:widow-orphan; font-size:11.0pt; mso-bidi-font-size:10.0pt; font-family:"Times New Roman"; mso-fareast-font-family:"Times New Roman"; mso-ansi-language:EN-US; mso-fareast-language:EN-US;}p {mso-style-priority:99; mso-margin-top-alt:auto; margin-right:0cm; mso-margin-bottom-alt:auto; margin-left:0cm; mso-pagination:widow-orphan; font-size:12.0pt; font-family:"Times New Roman"; mso-fareast-font-family:"Times New Roman"; mso-ansi-language:IN; mso-fareast-language:IN;}.MsoChpDefault {mso-style-type:export-only; mso-default-props:yes; font-size:10.0pt; mso-ansi-font-size:10.0pt; mso-bidi-font-size:10.0pt; mso-ansi-language:IN; mso-fareast-language:IN;}div.WordSection1 {page:WordSection1;}

Published: January 2024

Salah satu jenis profil baja yang cukup populer belakangan ini yaitu profil baja hollow. Baja hollow adalah salah satu jenis baja yang terdapat lubang kosong pada bagian tengahnya. Penggunaan baja hollow untuk komponen struktur pada bangunan masih sangat jarang ditemukan. Hal ini disebabkan karena ketebalan baja hollow yang sangat tipis jika dibandingkan dengan tulangan biasa dan terdapat rongga kosong yang mudah tertekuk jika diberikan beban. Untuk mengatasi hal tersebut, mortar digunakan sebagai pengisi rongga kosong pada baja hollow. Penelitian ini akan merencanakan sebuah inovasi dengan menempatkan rangka bidang baja hollow pada struktur bawah bangunan seperti pondasi. Oleh karena itu, diperlukan sebuah upaya untuk melindungi rangka bidang tersebut agar terhindar dari korosi yaitu dengan merancang suatu rangka bidang yang diselimuti oleh beton sehingga terbentuk struktur balok beton yang dikuatkan oleh rangka bidang baja hollow yang terisi mortar. Tujuan yang ingin dicapai pada penelitian ini adalah untuk mengetahui nilai kapasitas dan daktilitas balok beton yang diperkuat oleh rangka bidang baja hollow yang terisi mortar dengan variasi tinggi rangka. Penelitian ini menguji 3 buah balok beton yang divariasikan berdasarkan ketinggian rangka yaitu 400 mm, 500 mm dan 600 mm. Setiap benda uji diberi nama RBT40, RBT50, dan RBT60. Hasil penelitian menunjukkan bahwa adanya pengaruh pemakaian beton yang menyelimuti rangka bidang terhadap nilai kapasitas dan daktilitas, dimana semakin tinggi rangka bidang maka kapasitas balok beton dalam menahan beban semakin baik namun pada nilai daktilitas menunjukkan hasil yang berbanding terbalik.

Material Modeling in Additive Manufacturing
Authors: Spear Ashley D. 
Published: January 2024

Abstract
This article focuses specifically on material modeling applied to structure-property predictions. It provides general guidelines and considerations in terms of modeling the salient material features that ultimately impact the mechanical performance of parts produced by additive manufacturing (AM). Two of the primary ingredients needed to predict structure-property relationships via material modeling include a geometrical representation of the microstructural features of interest (e.g., grain structure and void defects) and a suitable constitutive model describing the material behavior, both of which can be scale and resource dependent. The article also presents modeling challenges to predict various aspects of (process-) structure-property relationships in AM.

Published: January 2024

Background: There are currently no recommendations on the therapeutic management of Parkinson’s disease (PD) patients at the end of life. Objective: To describe a cohort of patients with PD who benefited from continuous subcutaneous apomorphine infusion (CSAI) initiation at the end of their life as comfort care. Methods: This real-life cohort includes 14 PD patients, who benefited from 24-h, low-dose CSAI (0.5–3 mg/h) in the context of terminal care. Patient’s comfort (pain, rigidity, and/or ability to communicate) and occurrence of CSAI-related side-effects (nausea/vomiting, cutaneous and behavioral manifestations) were evaluated based on medical records. Results: All patients (age 62–94 years, disease duration 2–32 years) presented with late-stage PD and a compromised oral route. Treatment lasted from a few hours to 39 days. CSAI led to substantial functional improvement, with a good safety profile. Overall clinical comfort was deemed improved by the medical team, the patient, and/or caregivers. Conclusions: CSAI might be a promising approach in PD terminal care, as it reduces motor symptoms and overall discomfort, with an apparent good safety profile. Use of the apomorphine pen, sublingual film or a classic syringe pump might be considered when apomorphine pumps are not available. Larger observational cohorts and randomized controlled trials are needed to establish the efficacy and tolerability of apomorphine in the context of terminal care and more broadly, in an advance care planning perspective.

Published: January 2024

AIM: This study assessed the myocardial infarction (MI) using a novel fusion approach (multi-flavored or tensor-based) of multi-parametric cardiac magnetic resonance imaging (CMRI) at four sequences; T1-weighted (T1W) in the axial plane, sense-balanced turbo field echo (sBTFE) in the axial plane, late gadolinium enhancement of heart short axis (LGE-SA) in the sagittal plane, and four-chamber views of LGE (LGE-4CH) in the axial plane. METHODS: After considering the inclusion and exclusion criteria, 115 patients (83 with MI diagnosis and 32 as healthy control patients), were included in the present study. Radiomic features were extracted from the whole left ventricular myocardium (LVM). Feature selection methods were Least Absolute Shrinkage and Selection Operator (Lasso), Minimum Redundancy Maximum Relevance (MRMR), Chi-Square (Chi2), Analysis of Variance (Anova), Recursive Feature Elimination (RFE), and SelectPersentile. The classification methods were Support Vector Machine (SVM), Logistic Regression (LR), and Random Forest (RF). Different metrics, including receiver operating characteristic curve (AUC), accuracy, F1- score, precision, sensitivity, and specificity were calculated for radiomic features extracted from CMR images using stratified five-fold cross-validation. RESULTS: For the MI detection, Lasso (as the feature selection) and RF/LR (as the classifiers) in sBTFE sequences had the best performance (AUC: 0.97). All features and classifiers of T1 + sBTFE sequences with the weighted method (as the fused image), had a good performance (AUC: 0.97). In addition, the results of the evaluated metrics, especially mean AUC and accuracy for all models, determined that the T1 + sBTFE-weighted fused method had strong predictive performance (AUC: 0.93±0.05; accuracy: 0.93±0.04), followed by T1 + sBTFE-PCA fused method (AUC: 0.85±0.06; accuracy: 0.84±0.06). CONCLUSION: Our selected CMRI sequences demonstrated that radiomics analysis enables to detection of MI accurately. Among the investigated sequences, the T1 + sBTFE-weighted fused method with the highest AUC and accuracy values was chosen as the best technique for MI detection.
Openfoam Simulations for Development of a Mist Flow Diverter in Aerosol Jet Printing
Authors: Feng James Q. 
Published: January 2024

The Aerosol Jet® (AJ) direct-write technology enables material deposition for producing micron-scale fine features on various substrates with almost arbitrary geometry, which is of particular interest in manufacturing 3D conformal electronics among other applications. It operates by delivering an aerosol mist stream consisting of micron-size “ink” droplets, through an aerodynamic focusing nozzle with co-flowing sheath gas in a tapered channel, to the substrate several millimetres away with an impinging jet flow [1]. The ink pattern produced with AJ printing is essentially controlled in a “vector drawing mode” by the relative motion of the substrate with respect to the deposition nozzle. When a constant mist flow rate is fed into the deposition head, a mechanism for stopping the mist flow toward substrate must be implemented to prevent ink deposition in places where ink is undesired along the substrate moving toolpath. In other words, the mist stream toward substrate needs to be switched off at the time when the places of substrate where ink deposition is unwanted are moved under the AJ deposition nozzle, and to be switched on at the time when ink deposition is wanted. For the mist flow toward substrate, it can be considered as a function of time with on or off at certain time points. Here we describe a vacuum-boost diverter for rapid mist flow on-and-off switching in AJ printing, with OpenFOAM® simulations to aid its development and to offer fundamental understanding of its operational behaviour.
