A comprehensive analysis of kinetic modeling in dry reforming of methane

Dry reforming of methane (DRM) is a key reaction for syngas production from greenhouse gases (methane and carbon dioxide). Reaction kinetics predict reaction rates, identify and understand reaction mechanisms, and guide catalyst and reactor design. To provide a clear sense of pro...

Examining Anxiety as an Additional Antecedent to Trust and Commitment in Financial Planning

Abstract Drawing on Morgan and Hunt’s (1994) theory of trust and commitment, this study extends prior research by examining financial anxiety as an antecedent to trust and relationship commitment in client-planner relationships. Survey data from 430 financial planning clients wer...

Coupled surface-groundwater modeling of water stress-triggered irrigation and climate change effects on maize production in Southwestern Kansas

Sustained groundwater depletion in the Ogallala Aquifer threatens the long-term viability of irrigated agriculture in the U.S. High Plains. This study evaluates deficit irrigation as an adaptation strategy using the coupled surface–groundwater model SWAT + gwflow in the Sunset Me...

Supercritical Technology Applied to Food, Pharmaceutical, Chemical and Energy Industries—2nd Edition

The unique dual properties of supercritical fluids—the dissolving power of liquids combined with the low viscosity and high diffusivity of gases—make these substances attractive for a wide range of applications, including the extraction of solid materials, fractionation of substa...

Effects of particle grind size in extruded diets on Pacific white shrimp Litopenaeus vannamei growth performance

Abstract There is limited information on the impact of particle grind size in extruded aquaculture diets. Hence, the purpose of this research was to evaluate the effect of extruded diets with different particle grind sizes, with 95% of particles being below, 100, 180, 325, 475, a...

Hyporheic eDNA Removal Outweighs Water Column Degradation in a Natural River

Abstract Advances in the measurement of environmental DNA (eDNA) have transformed biodiversity monitoring in aquatic ecosystems. However, linking eDNA concentrations in streams and rivers to species abundance remains challenging as flowing water, streambed retention, and degradat...

From Perception to Protection: How Fraud Worry Shapes Investor Behavior

This study develops an integrated conceptual framework to examine the association between investors’ subjective perception of being targeted by investment fraud and their adoption of protective coping behaviors. Drawing on the transactional model of stress and coping, the paper p...

Influence of Limit-Feeding Duration on Growth Performance and Carcass Traits of Finishing Steers

Abstract Beef cattle are commonly limit-fed during the backgrounding period to improve feed efficiency and control fat deposition, but the effects of limit feeding duration in the finishing period remains unclear. The objective of this study was to determine the effect of limit f...

Genetic architecture and evolution of stripe rust resistance uncovered using diverse panels of wheat lines and North American Puccinia striiformis f. sp. tritici isolates

Abstract Key message Screening global wheat germplasm with a diverse collection of pathogen races expands the catalog of novel Yr loci and identifies new sources of broad-spectrum resistance against evolving Pst populations. Abstract Newly emerging highly virulent races of Puccin...

Influence of soil amendments and crop rotation systems on weed diversity, biomass and cover in Sudano-Sahelian Africa

Weed management represents a critical challenge in Sudano-Sahelian agriculture, where environmental constraints and soil fertility limitations create complex weed–crop competition dynamics. This study determined the effects of cropping systems, fertilization modes, and weeding pe...

School day physical activity profiles and transitions across the school year: a latent analysis in 8–9 year-old children

Abstract Background School day physical activity (PA) is important for children’s health and development, yet longitudinal evidence on within-year trajectory patterns is limited. Traditional approaches to studying PA change may obscure substantial heterogeneity in how individual...

I2M: a box-based detection framework for molecular structure recognition from images

Accurate recognition and reconstruction of chemical structures from molecular images is critical in cheminformatics, with applications spanning drug discovery, materials science, and patent analysis. However, much of this chemical matter exists in implicit forms that are not dire...

Structural dynamics during the three-ion Coulomb explosion of highly charged CS2 in intense soft x-ray pulses

Using intense femtosecond soft x-ray pulses above the sulfur 2p edge produced by the Free-electron LASer in Hamburg (FLASH), we investigate the multiple ionization and fragmentation dynamics of CS2. We focus on the three-ion fragmentation pathways of CS2 polycations with total ch...

Gas flux determination and prediction of methane emissions in yearling steers under grazing conditions

Context The use of an automated head chamber system (AHCS) for determining methane (CH4) emissions in ruminants has increased in recent years; however, assessments of emissions in grazing systems remain limited, constrained by a lack of knowledge regarding the minimum number of A...

Feeding regime alters mitochondrial metabolism in beef skeletal muscle

Abstract Plane of nutrition influences animal growth rate and muscle fiber composition, potentially through altering skeletal muscle metabolism. The objective of this study was to evaluate changes in skeletal muscle metabolism in response to altering diet without changes in growt...

Viral dissemination and diagnostic insights from experimental infection of sheep with Crimean-Congo hemorrhagic fever virus

Abstract Crimean-Congo hemorrhagic fever virus (CCHFV) is a tick-borne orthonairovirus widely distributed across Asia, Africa, the Middle East, and Southern Europe, causing severe illness and hemorrhagic fever in humans. While sheep usually show no clinical symptoms, they develop...

Epidemic mean-field thresholds of SIS dynamics on temporal multiplex networks with activity-driven layers

Abstract We investigate the susceptible--infected--susceptible (SIS) process on a temporal multiplex network where a persistent static layer is overlaid with an activity-driven layer of one-step contacts. Simulations on several random network families (Erd\H{o}s--R\'enyi, Watts--...

Ensemble agroecosystem modeling enhances predictions of crop yields and soil carbon across the United States

Abstract. Accurately estimating crop yields and soil organic carbon (SOC) dynamics is essential for agricultural planning, carbon accounting, and sustainable land management. However, process-based agroecosystem models often produce divergent estimates due to variations in model...

Improved specificity of a probe-based real-time PCR for the detection of Dirofilaria immitis in canine blood

Abstract Background Dirofilaria immitis is a vector-borne filarioid nematode distributed worldwide and endemic across most of North America. In dogs, it is considered the most important parasite and a known cause of acquired cardiomyopathy. Clinically, canine heartworm disease ca...

The effects of dietary iron supplementation on bacterial infections in Manduca sexta larval hemolymph

Abstract Iron is an essential nutrient for all types of organisms, including insects and the microbes that infect them. We predicted that insects fed an iron-supplemented diet would accumulate more iron in their hemolymph, and, because infectious microbes acquire iron from their...
