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.

Prediction of Coarse Aggregate Performance by Micro-Deval and Other Soundness, Strength, and Intrinsic Particle Property Tests [PDF]

Transportation Research Record: Journal of the Transportation Research Board, 2007
Aggregate samples were collected from the majority of the U.S. states, as well as several Canadian provinces, and subjected to micro-Deval, Los Angeles abrasion, magnesium sulfate soundness, Canadian freeze-thaw, aggregate crushing value, absorption, specific gravity, and particle shape characterization testing to determine whether a correlation exists

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

Laboratory and numerical analysis for enhanced ballast performance: towards sustainable railway track pavement design

Transportes
The physical and mechanical characterization of rock materials is a crucial step for their applicability as a railway ballast layer. However, most of the standardized tests for such characterization do not have direct application for the ballast layer ...
