Growth and Physiological Performance of Aerobic and Lowland Rice as Affected by Water Stress at Selected Growth Stages

Rice Science, 2018
Aerobic rice technology is still new in Malaysia, and information regarding MARDI Aerob 1 (MA1), the first local aerobic rice variety, is still lacking. Therefore, comparative studies were carried out to determine the physiological performance of aerobic

Elucidation of void defects by soft reduction in medium carbon steel via EBSD and X-ray computed tomography

Materials & Design, 2021
In this work, void formation in medium carbon ferrite-pearlite steel is investigated with soft reduction (SR) technology as regards its initiation sites and governing factors: prior austenite grain size, grain boundary ferrite (GB-α) precipitation ...

Evidence that abnormal grain growth precedes fatigue crack initiation in nanocrystalline Ni-Fe

, 2018
Prior studies on the high-cycle fatigue behavior of nanocrystalline metals have shown that fatigue fracture is associated with abnormal grain growth (AGG).

Effect of Nucleant Particle Agglomeration on Grain Size

Metallurgical and Materials Transactions. A, 2022
Solute accumulation/depletion in the liquid around a growing solid particle during the solidification of metallic melts creates a constitutionally supercooled (CS) zone that has a significant effect on the final solidified grain structure. In this paper,

Understanding Further the Phenotypic Spectrum of Central Nervous System Inflammatory Demyelinating Disorders Using Unsupervised Clustering

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Central nervous system (CNS) inflammatory demyelinating syndromes, including multiple sclerosis (MS), aquaporin‐4 antibody–positive neuromyelitis optica spectrum disorder (AQP4 + NMOSD), and myelin oligodendrocyte glycoprotein (MOG) antibody–associated disease (MOGAD), occasionally overlap.

Initiation and Development of Spikelets and Florets in Wheat as Influenced by Shading and Nitrogen Supply at the Spikelet Phase

Plant Production Science, 2001
The spike of the main culm in winter wheat was examined by scanning electron microscopy from the double ridge to 6 days after the terminal spikelet stage to quantitatively evaluate the effects of shading and nitrogen supply at the spikelet phase on the ...

Microstructural characterisation of brittle fracture initiation sites in reactor pressure vessel steels

Nuclear Materials and Energy, 2023
Neutron embrittlement of reactor pressure vessel (RPV) steels potentially limits the safe operational time of nuclear reactors. In tested RPV steel samples microcracks are known to originate from cleaved precipitates, inclusions or grain boundaries ...

Grain Futures Market Response to the Black Sea Grain Initiative

German Journal of Agricultural Economics
This paper assesses the impact of the Black Sea Grain Initiative on the grain futures market. We rely on counterfactual evaluation techniques and detailed futures price series to estimate how corn and wheat futures prices and historical volatility responded to the Grain Deal enforcement, renewals, and termination.

Spatial and Volumetric Characteristics of Glioblastoma: Associations With Clinical Presentation and Survival

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective We aim to comprehensively analyze how regional tumor and edema characteristics are associated with clinical presentations and survival outcomes in a large cohort of glioblastoma patients. Methods Patients with IDH‐wildtype glioblastoma who received brain MRI from 2010 to 2023 were included.
