Investigation of evaluation indicators of agglomeration degree of recycled asphalt pavement materials

Frontiers in Materials
High-content reclaimed asphalt pavement (RAP) utilization is becoming a promising direction to achieve sustainable pavement maintenance. However, the agglomerate degree of RAP materials is hard to be accurately quantified.

From Practitioner to Scholar: A Collaborative Autoethnography of PhD Students' Research on Evaluation Journeys

New Directions for Evaluation, Volume 2025, Issue 187, Page 67-82, Fall 2025.
ABSTRACT There has been limited attention to the role of research on evaluation (RoE) in PhD‐level evaluator education. Previous research suggests that evaluator education doctoral programs have multiple purposes to prepare practitioners and researchers, thus creating an unnamed tension where evaluation practice is the focus and RoE has not been ...

Laboratory-to-field geotechnical suitability assessment of granular lateritic materials-crushed rock aggregate mixture for tropical pavements

Discover Civil Engineering
Granular lateritic materials (GLM), widely used in tropical regions for their availability and low cost, often exhibit high variability and inadequate bearing capacity to satisfy pavement design requirements.

Physico‐Mechanical, Mineralogy, and Microstructural Properties and Durability of Mortars Made With Alluvial Sands

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
Concrete structures built from local materials are prolific, and mastery of their intrinsic properties is a guarantee of rational use. This study, based on an experimental approach, analyzes the construction potential of three alluvial sands (Mandikoum [MA], Ndom [ND], and Vack [VA]) used in Adamawa.

Mix and measure II: joint high‐energy laboratory powder diffraction and microtomography for cement hydration studies

Journal of Applied Crystallography, Volume 57, Issue 4, Page 1067-1084, August 2024.
Laboratory powder diffraction and microtomography techniques are sequentially used in the same volume of the same sample to study the process of cement hydration with time.Portland cements (PCs) and cement blends are multiphase materials of different fineness, and quantitatively analysing their hydration pathways is very challenging.

Human‐based new approach methodologies to accelerate advances in nutrition research

Food Frontiers, Volume 5, Issue 3, Page 1031-1062, May 2024.
Much of nutrition research has been conventionally based on the use of simplistic in vitro systems or animal models. Here, we describe the main novel available and emerging tools that are appropriate for designing a more human‐relevant nutrition research.

Effect of biofloc technology in Farfantepenaeus aztecus culture: The optimization of dietary protein level on growth performance, digestive enzyme activity, non‐specific immune response, and intestinal microbiota

Journal of the World Aquaculture Society, Volume 55, Issue 2, April 2024.
Abstract In this study, a biofloc technology (BFT) based 90‐day feeding trial was performed to estimate the effects of four different dietary protein levels (290, 320, 350 and 380 g protein kg−1 diet; 29P, 32P, 35P, and 38P, respectively) on growth performance, digestive enzyme activity, non‐specific immune response, whole‐body proximate and fatty acid
