Land-use and tillage contrasts in soil aggregate stability and near-surface shear resistance in a subtropical headwater catchment

Aggregate stability and near-surface shear resistance represent complementary expressions of soil structural condition, yet it remains unclear whether they respond similarly to land use and tillage or are associated with different soil properties across heterogeneous headwater ca...

Assessing the sensitivity of onion ( Allium cepa ) cultivars to defoliation levels across different growth stages

Onion (Allium cepa) yield is susceptible to the occurrence of climatic events such as hail, which can decrease the leaf area of plants and the yield and quality of bulbs. The study aimed to evaluate whether defoliation levels at different development stages of the onion cultivars...

Ellagic acid regulates astrocytic responses under inflammatory conditions in primary astrocyte cultures: effects on oxidative stress, inflammatory cytokines, and glycogen synthase kinase-3β

Abstract Background Neuroinflammation involves the activation of glial cells, particularly astrocytes, and microglia, in response to pathological stimuli. Astrocyte activation is characterized by increased pro-inflammatory cytokines and oxidative stress. Given their role in neuro...

Data-Driven Framework Integrating Database Analysis and Bayesian Segmented Quantile Regression to Determine Critical Nutrient Levels in Soil and Leaves of Peach Trees

Fertilization recommendations are frequently proposed by a limited number of calibration experiments conducted in a few regions, with few cultivars. Thus, recommendations concerning nutrients’ critical levels (CLs) and sufficiency ranges (SRs) are not always the most suitable one...

The effects of executive compensation disclosure in countries with weak legal protection

Purpose This research examines the impact of mandatory executive compensation disclosure on firm risk and liquidity in countries characterized by weak legal protection. Design/methodology/approach Adopting a quasi-experimental approach, the study uses the difference-in-difference...

Transformational leadership for environmental sustainability (TLES)

Purpose This study aims to adapt and expand the scale developed by Robertson (2018) to assess perceptions of Transformational Leadership for Environmental Sustainability (TLES). Design/methodology/approach To achieve this, 21 items were constructed using a five-point Likert scale...

Characterization of Cry2Ab2 resistance in Crocidosema sp. (Lepidoptera: Tortricidae): resistance selection, inheritance, cross‐resistance patterns, and fitness costs

Abstract BACKGROUND The soybean bud borer, Crocidosema sp., evolved field resistance to Cry1Ac soybean in Brazil, raising concerns regarding the durability of Bacillus thuringiensis (Bt) soybean technologies and potential evolution of resistance to additional Bt proteins. Here, a...

Microstructural Evolution and Morphological Aspects of Titanium Carbides in Weld-Deposited Coatings using Chip-Based Fluxes

Abstract This work examines how joint design–controlled dilution governs microstructural evolution and titanium carbide morphology in GTAW cladded hardfacing layers produced using recycled Ti6Al4V chips and graphite. Hardfacing coatings were deposited into V-groove geometries of...

Dense and Cold Magnetized Quark Matter: A Review of Magnetic-Field-Independent Regularization and the Medium Separation Scheme

We present a comprehensive review of regularization schemes for magnetized dense quark matter within effective models of quantum chromodynamics, focusing on the Magnetic-Field-Independent Regularization (MFIR) and the Medium Separation Scheme (MSS) at finite chemical potential an...

Acidified Acetonitrile Extraction and Ultra-High Performance Liquid Chromatography–Tandem Mass Spectrometry for Multiresidue Determination of 136 Pesticides in Tahiti Lime (Citrus latifolia)

The determination of pesticide residues in citrus fruits remains analytically challenging due to their high acidity and complex chemical compositions, which can compromise extraction efficiency and promote significant matrix effects, particularly for acidic compounds. In this stu...

Effect of chocolate preference and cocoa content on experimentally induced muscle pain

Abstract Objectives Chocolate consumption has been associated with pain reduction, but it remains unclear whether this effect depends on cocoa concentration or individual preference. This study aimed to investigate whether chocolate preference and/or cocoa content modulate experi...

Effects of Adding Incentive Spirometry to Hospital‐Based Cardiovascular Rehabilitation on Pulmonary Complications, Hospital Length of Stay, and Clinical‐Functional Recovery After Cardiac Surgery: A Randomized Controlled Trial

ABSTRACT Background and Purpose This study investigated the effects of combining incentive spirometry with cardiac rehabilitation compared with cardiac rehabilitation alone on postoperative pulmonary complications, clinical‐functional recovery, and hospital length of stay in pati...

From Host–Guest to Crystal Interactions: Proposing Crystallization Mechanisms for a Novel β-CD/TTA-H Structure and Related Cyclodextrin Inclusion Complexes

Abstract Cyclodextrin inclusion complexes (ICs) have been extensively studied for their capacity to modulate the physicochemical properties of guest molecules, albeit their solid-state organization has been comparatively less explored. In particular, the relationship between host...
