Microfocus X-ray sources for 3D microtomography [PDF]

, 1994
An analytic model for the performance of cone beam microtomography is described. The maximum power of a microfocus X-ray source is assumed to be approximately proportional to the focal spot size.

Comparison of Methods to Segment Variable-Contrast XCT Images of Methane-Bearing Sand Using U-Nets Trained on Single Dataset Sub-Volumes

Methane, 2022
Methane (CH4) hydrate dissociation and CH4 release are potential geohazards currently investigated using X-ray computed tomography (XCT). Image segmentation is an important data processing step for this type of research.

Morphological and elemental mapping of gallstones using synchrotron microtomography and synchrotron X‐ray fluorescence spectroscopy

JGH Open, 2019
Background and Aim Regional differences in gallstone (GS) composition are well documented in the Indian subcontinent. The reasons for the same are unknown. Etiopathogenesis of GS remains elusive despite advances in instrumentation.

ALIGNING MICROTOMOGRAPHY ANALYSIS WITH TRADITIONAL ANATOMY FOR A 3D UNDERSTANDING OF THE HOST-PARASITE INTERFACE – PHORADENDRON SPP. CASE STUDY

Frontiers in Plant Science, 2016
The complex endophytic structure formed by parasitic plant species often represents a challenge in the study of the host-parasite interface. Even with the large amounts of anatomical slides, a three-dimensional comprehension of the structure may still be

Looking at Soil as It Is: Evolution of Microscopic Soil Characterization From Kubiëna to Artificial Intelligence

Journal of Plant Nutrition and Soil Science, EarlyView.
We provide a historic overview of microscopic soil structure characterization from its founding father, Walter Kubiëna, to several technical revolutions like automation, digitalization, and artificial intelligence. In addition to technical advancements, we explore how concepts and research questions have evolved in time.

Arabinoxylan‐enriched fraction from durum wheat meal modulates structure, texture, nutritional and sensory properties of extruded snacks

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Arabinoxylans (AX), abundant in wheat bran, represent a valuable yet underutilized fraction of cereal milling by‐products. In this study, an AX‐enriched fraction obtained from durum wheat meal (DWM), produced from defatted durum wheat germ and debranning fractions, was incorporated at increasing levels (0–25%) into pea starch ...

Influence of Hybrid Co‐wrapped Yarn Structure on the Energy Absorption and Crack Propagation Resistance of Fiber‐Reinforced Composites

Polymer Composites, EarlyView.
Helical wrapping of polyamide around E‐glass fibres deflects and bridges impact‐driven cracks, arresting damage that would otherwise propagate catastrophically in conventional side‐by‐side hybrid yarns. ABSTRACT Hybrid cowrapped (CW) yarns were engineered to enhance the impact resistance and damage tolerance of fiber‐reinforced composites.
