Optical Transmission Spectra of Pb_(0.80) Sr_(0.20) TiO_3/Pb_(0.90) Sr_(0.10) TiO_3 Compositional Graded Ferroelectric Thin Films

/in /by

This study looks at the optical transmission properties of ferroelectric thin films made from two different compositions of lead strontium titanate:  and . The films were created using a method called metallo-organic decomposition (MOD) combined with spin coating on quartz substrates. The researchers analyzed the optical properties by recording transmission spectra from 300 to 1500 […]

Effect of Stirring Circulation on the Effectiveness of Microbial Consortium in Sludge Oil Bioremediation Process

/in /by

Sludge oil is a by-product of crude oil processing that poses significant environmental and efficiency challenges in the oil and gas industry. This study aims to evaluate the effectiveness of using microbial consortia to address sludge oil, with a focus on the impact of agitation on oil recovery enhancement. An experimental and laboratory analysis approach […]

Behavior-Based Purchase Intent Prediction in E-Commerce: A Machine Learning Approach

/in /by

This study investigates the use of machine learning to predict user purchase intentions based on behavioral data in a multi-category e-commerce platform. By analyzing seven months of user interaction logs—comprising product views, cart additions, and purchases—the research applies feature engineering to generate variables such as event weekday, product category levels, session activity count, and cart-to-view […]

Nasal Hemangioma and the Importance of Preoperative Embolization: Case Report and Literature Review

/in /by

Nasal hemangioma is a rare benign vascular neoplasm, yet clinically significant due to its hemorrhagic potential within a richly vascularized anatomical region. Its therapeutic management requires a multidisciplinary approach, particularly in cases indicated for surgical resection. Preoperative arterial embolization has proven to be an effective tool for controlling intraoperative bleeding, facilitating complete excision, and improving […]

Puff of Smoke’ In A Young Brain: A Classic Imaging Sign of Moyamoya Disease – Case Report

/in /by

Moyamoya disease is a rare and progressive cerebrovascular disorder marked by the occlusion or blockage of the distal internal carotid arteries and their main branches. In response, the brain develops a network of fragile collateral vessels, which appear as a “puff of smoke” on angiographic imaging—a characteristic feature that inspired the disease’s name. The condition […]

Legal Certainty in the Management and Supervision of Donations for Humanitarian Purposes in Indonesia

/in /by

The rapid progress of information technology has greatly enhanced public fundraising via donation-based crowdfunding platforms that use social media and digital channels. This innovation expands public access and fosters community involvement in social initiatives, yet it functions within a framework of legal ambiguity due to the lack of specific regulations governing the mechanisms, oversight, and […]

The Development of RBL-STEAM Learning Design to Improve Climate Change Literacy Through the Construction of Energy-Efficient Houses in Sixth Grade of Elementary School Students

/in /by

Climate change literacy is essential for preparing future generations to understand environmental challenges and take an active role in mitigation and adaptation efforts. This study aims to enhance students’ climate change literacy through the development of Research-Based Learning (RBL) integrated with the STEAM approach, which combines Science, Technology, Engineering, Arts, and Mathematics. Students were engaged […]
