On the Scavenging of Two-Stroke Diesel Engine : (Scavenging Process in Cross-Scavenging System)

open access: bronzeTransactions of the Japan Society of Mechanical Engineers, 1961
This paper reports the results of an investigation on the scavenging process in a model cylinder having a cross-scavenging system. The movement of the scavenge front in the cylinder and the short-circuiting of fresh charge were investigated by an electronic method. The profile of the scavenge front was made clear. The port arrangement investigated here

Intracellular monitoring by dendritic cells – a new way to stay informed – from a simple scavenger to an active gatherer

open access: yesFrontiers in Immunology, 2022
Dendritic cells (DCs) are required for the initiation of the adaptive immune response. Their ability to acquire antigens in the periphery is a critical step in this process.

Why Ortho- and Para-Hydroxy Metabolites Can Scavenge Free Radicals that the Parent Atorvastatin Cannot? Important Pharmacologic Insight from Quantum Chemistry [PDF]

open access: yesMolecules, 27 (15), 5036 (2022), 2022
The pharmaceutical success of atorvastatin (ATV), a widely employed drug against the "bad" cholesterol (LDL) and cardiovascular diseases, traces back to its ability to scavenge free radicals. Unfortunately, information on its antioxidant properties is missing or unreliable.

Surface activation by electron scavenger metal nanorod adsorption on TiH2, TiC, TiN, and Ti2O3 [PDF]

open access: yesPhys. Chem. Chem. Phys., 2021,23, 16577-16593, 2023
Metal/oxide support perimeter sites are known to provide unique properties because the nearby metal changes the local environment on the support surface. In particular, the electron scavenger effect reduces the energy necessary for surface anion desorption, thereby contributes to activation of the (reverse) Mars-van Krevelen mechanism.

Hemoglobin and heme scavenging [PDF]

open access: yesIUBMB Life (International Union of Biochemistry and Molecular Biology: Life), 2005
Release of hemoglobin into plasma is a physiological phenomenon associated with intravascular hemolysis. In plasma, stable haptoglobin-hemoglobin complexes are formed and these are subsequently delivered to the reticulo-endothelial system by CD163 receptor-mediated endocytosis.

Contrasting Behaviors of 210Pb and 210Po in the Productive Shelf Water Versus the Oligotrophic Water

open access: yesFrontiers in Marine Science, 2021
We measured the total, truly dissolved (<10 kDa), colloidal (10 kDa–0.2 μm), and particulate phases (>0.2 μm) of 210Pb and 210Po in the East China Sea (ECS) shelf water and the East Sea (Japan Sea).

The impact of scavenging: perspective from casework in forensic anthropology

open access: yesForensic Sciences Research, 2020
Forensic anthropology casework frequently encounters evidence of animal scavenging associated with fragmentation and loss of skeletal material. Published research demonstrates that patterns of destruction in bone can suggest the size and type of animal ...

Scavenger community response to the removal of a dominant scavenger [PDF]

open access: yesOikos, 2011
The alteration of scavenging communities can reduce basic ecosystem services and increase risks to human and wildlife health. Recent work demonstrated that scavenging communities in agricultural landscapes are extremely efficient: superabundant mesopredators sequestered system energy by dominating scavenging activity.
