Multiscale Thermal Performance Transfer In Fly-Ash-Modified Recycled Fine Aggregate Concrete For Climate-Dependent Wall Response, Jiayu Zhao, Norul Wahida Kamaruzaman Sep 2026

Multiscale Thermal Performance Transfer In Fly-Ash-Modified Recycled Fine Aggregate Concrete For Climate-Dependent Wall Response, Jiayu Zhao, Norul Wahida Kamaruzaman

Platform: A Journal of Engineering (PAJE)

This study develops a multiscale analytical framework to quantify how thermal conductivity changes in fly-ash-modified recycled fine aggregate concrete (FA-RFAC) transfer to wall and climate-response scales. Five conductivity scenarios (0.60–1.40 W/(m·K)) were evaluated using a standardised multi-layer reference wall, and transfer was quantified using local transfer elasticity and a finite-change thermal-performance retention factor. The resulting wall U-values were combined with heating and cooling degree-days for Beijing, Shanghai, and Guangzhou. The local transfer elasticity was mathematically equivalent to the fraction of total wall resistance provided by the FA-RFAC layer. At the reference conductivity of 1.00 W/(m·K), FA-RFAC and rock wool contributed …

Event-Resolved Rqdf Characterisation Of Berea Sandstone: Distinguishing Pore-Structure Similarity From Scale-Dependent Variability, Walid Mohamed Mahmud Sep 2026

Event-Resolved Rqdf Characterisation Of Berea Sandstone: Distinguishing Pore-Structure Similarity From Scale-Dependent Variability, Walid Mohamed Mahmud

Platform: A Journal of Engineering (PAJE)

This paper applies the Rate-Controlled-Porosimetry Quantitative Descriptor Framework (RQDF) to four Berea sandstone core plugs. Events were identified using an automated, prominence-based detection algorithm, which was validated against an independently documented manual event count for two of the four plugs. The finding is an empirical shape-scale separation among these four plugs. Descriptors that are invariant by construction under rescaling of the underlying pore-size distributions, namely event-size entropy, distributional and power-law exponents, and curve-region saturation boundaries, reproduce across the four plugs with a coefficient of variation below 8%. Median effective capillary-equivalent pore-throat radius is also stable at this level (CV about …

Strengthening The Philippines' Agri-Fishery Rde System: A Case Study Of A Public Coordinating Agency As A Bridging Organization, Cynthia Remedios V. De Guia, Luis Rey I. Velasco, Maria Faina L. Diola

Journal of Public Affairs and Development

The Philippine agricultural research, development, and extension (RDE) system has long struggled to live up to its ideals. Decades after the passage of the Agriculture and Fishery Modernization Act (AFMA), the RDE system was reported to have failed to innovate, largely because it failed to translate research into development outcomes. This has resulted from persistent gaps in knowledge exchange, institutional linkages, and collaboration among system actors. In fragmented systems, meaningful interaction and trust seldom emerge spontaneously, making bridging mechanisms necessary. Bridging organizations (BOs) play this role by connecting multiple and diverse actors, mediating relationships, enabling knowledge flows, and enhancing capacities …

The Effect Of Alpha-Lipoic Acid On Sperm Cryobiology And Post-Thaw Quality Of Sperm In Livestock Species, Kashif Ali Malak, Nazar Ali Korejo, Hira Sajjad Talpur, Asmatullah Kaka, Atif Ali Malak, Muhammad Aqeel, Rasool Bux

Journal of Bioresource Management

The cryopreservation of semen is a prerequisite for artificial insemination, germplasm banking and the global distribution of elite livestock breeding. However, spermatozoa are particularly sensitive to cooling and freezing/thawing processes due to the presence of large amounts of polyunsaturated fatty acids in their plasma membranes and limited cytoplasmic antioxidant stores. An increase in reactive oxygen species, lipid peroxidation, mitochondrial dysfunction, acrosomal injury and DNA fragmentation occurs due to stress associated with cryopreservation, which results in the lowering of motility as well as viability and post-thaw low quality of sperm. Alpha-lipoic acid is a natural disulfide compound that acts as a …
