Experimental Study on the Mechanical Properties of Concrete Using GGBS and Pond Ash with Glass Fiber Reinforcement

Concrete is the most widely used construction material globally due to its versatility, durability, and cost-effectiveness. However, the production of conventional concrete requires a substantial amount of cement and sand, which leads to environmental concerns and depletion of natural resources. In the present study, an attempt has been made to prepare the sustainable concrete using partial replacement of cement with GGBS and sand by pond ash with glass fiber. The cement and sand have been replaced by 20% and 40% by GGBS and pond ash, respectively. A constant proportion of fiber (0.1% of cement) is added to evaluate the combined effect on properties of concrete. The experimental tests on fresh concrete (i.e., workability) and hardened concrete (i.e., compressive strength test, flexural strength test, and ultrasonic pulse velocity test) were performed to study the effect of partial replacement of GGBS and pond ash in the concrete. Based on durability, replacement of 20% cement up to 40% sand is recommended by GGBS and pond ash, respectively, together with glass fiber.

Decentralized Document Verification by Smart Contracts: Lightweight Open-Source Solution Design and Implementation

With the current digital era, document authenticity and existence verification become increasingly valuable across industries, including legal services, intellectual property protection, and business regulation. Authenticity and existence verification via conventional methods is usually centralized and entity-dependent, which may introduce privacy concerns, points of failure, and extra expenses. This paper presents the design and construction of a decentralized document verification system as an open-source system using blockchain smart contracts to safely register cryptographic proofs of digital material. The solution emphasizes ease, privacy, and usability using just smart contracts without storing actual document information on-chain or off-chain. By allowing users to calculate cryptographic hashes locally and directly interact with the blockchain, the system preserves immutable, transparent, and verifiable records while not compromising on confidentiality.

Time Hierarchy in Practice: Empirical Evidence of Computational Class Separations

The Time Hierarchy Theorem states, in theory, that by providing more time, there exist strictly more problems that can be solved. However, most of these separations are very abstract and cannot be seen in a real computing environment. This paper investigates how algorithmic classes of different time complexities act under real-world time constraints. It does this by empirically evaluating standard algorithms with time complexities from O(n log n) to O(2ⁿ) and measuring the input sizes at which effective divergence is observed. The paper finds effective and observable diversions in line with theoretical expectations, empirically supporting theoretical hierarchies.

The Impact of Costume on Performance

This research paper seeks to examine the impact of costume on dance performance. A thorough literature review is undertaken, and it is discovered that technology and dance costume design, dancing constraints depending on costumes, types of materials related to the form of dance, representation/traditions in dance costumes, and audience perception and engagement have a significant impact on dance performance. All of these factors have an interdependent and complex relationship that is examined in detail.

Comparative Evaluation of Prophylactic Carbetocin versus Oxytocin in Prevention of Postpartum Hemorrhage Following Vaginal Delivery: A Randomized Controlled Trial

To compare the efficacy and safety of prophylactic carbetocin versus oxytocin in the prevention of postpartum hemorrhage (PPH) after normal vaginal delivery. Methods: This was a single-blind randomized controlled trial including 84 women undergoing vaginal delivery. Group A received 100 mcg IV carbetocin; Group B received 10 IU IM plus 10 IU IV oxytocin in 500 ml RL. Primary outcomes included postpartum blood loss and changes in hemoglobin/hematocrit levels. Secondary outcomes included the need for additional uterotonics, blood transfusions, and adverse effects. Results: Mean blood loss was significantly lower in the carbetocin group (197.36 ± 77.63 ml) compared to oxytocin (316.64 ± 107.71 ml, p=0.04). Postpartum hemoglobin and hematocrit decline were less significant in the carbetocin group (p<0.001). No significant differences were observed in the need for transfusion (p=0.69) or adverse effects (p=0.75). Conclusion: Carbetocin significantly reduces postpartum blood loss compared to oxytocin, with a comparable safety profile. Its use may be beneficial in resource-limited settings due to its heat stability and single-dose regimen. Keywords: postpartum hemorrhage, carbetocin, oxytocin, vaginal delivery, randomized controlled trial

Electronic Sensory Glove

The human hand is vital for daily and social functions, and its loss can significantly impact quality of life, often necessitating psychological intervention due to isolation, anxiety, or depression. While prosthetic hands restore essential mobility, challenges remain in achieving natural appearance and sensory feedback. This study presents the development of an electronic sensory glove (e-glove) system that seamlessly integrates multimodal sensors—capable of detecting pressure, temperature, and moisture—into a commercial stretchable nitrile glove. Leveraging a hybrid screen- and transfer-printing fabrication method, the e-glove conforms to various prosthetic hand shapes and sizes, offering realistic tactile qualities and real-time data transmission via a wristwatch interface. Both experimental and computational analyses validate the glove’s mechanical and functional efficacy, demonstrating its potential to enhance prosthetic hand interactions in diverse daily and social contexts.
