Analysis of a dual-spindle high-speed drilling machine head.

, 1994
Vibration characteristics of a high-speed spindle and Dual-Spindle High-Speed Drilling Machine Head were studied to determine if the modal, free-run, and cutting characteristics allow for a stable machining system at the required operating speed of 167 ...

High speed tooltip FRF predictions of arbitrary tool-holder combinations based on operational spindle identification

, 2018
The chatter vibrations in milling are avoided by selecting spindle speeds and depth of cuts from the stability lobes. However, it has been well observed that the structural dynamics of the spindle system change as a function of speed and even feed.

Ursolic Acid Alleviates Orchitis via Modulating Ferroptosis in Peritubular Myoid Cells of Testis

Animal Research and One Health, EarlyView.
Ursolic acid modulates key ferroptosis‐related pathways in the peritubular myoid cells of the testis in forest musk deer. ABSTRACT Chronic stress adversely affects reproductive health, increasing susceptibility to pathologies such as orchitis. Additionally, the maintenance of iron homeostasis is essential for preserving the function of the testicles ...

Effect of Drilling Parameters on Surface Roughness and Delamination of Ramie–Bamboo-Reinforced Natural Hybrid Composites

Journal of Manufacturing and Materials Processing
Plastics reinforced with glass fiber have a significant likelihood of being replaced by natural fiber hybrid composites (NFHCs). Making holes helps in part assembly, which is a crucial activity in the machining of composite constructions.

Enhancing Meat Quality Through Dietary Fiber: Insights Into the Gut Microbiota‐Derived Short‐Chain Fatty Acids‐Muscle Axis

Animal Research and One Health, EarlyView.
Dietary fiber (DF) modulates meat quality through the gut‐muscle axis by reshaping gut microbiota, improving intestinal integrity, reducing inflammation, and regulating muscle metabolism. These mechanisms influence muscle fiber characteristics and post‐mortem biochemistry, thereby enhancing tenderness, juiciness, color, flavor, and nutritional value of

2D copper nanozyme patches facilitate bone regeneration via interfacial modulation of osteoclast‐osteoblast dynamics

BMEMat, EarlyView.
This study develops a nano‐enzyme patch (ezPatch) targeting bone interfaces. Utilizing ligand‐to‐metal charge transfer (LMCT) catalysis and bone‐targeting ligands on copper nanosheets, ezPatch simultaneously scavenges reactive oxygen species (ROS) and generates oxygen in situ at bone‐losing sites.

Fungal Antimicrobial Resistance: Mechanisms, Drivers, and Global Clinical Burden

ChemFoodChem, EarlyView.
ABSTRACT Fungal antimicrobial resistance (AMR) is a growing concern for world health caused by an increase in multidrug‐resistant infections, an increase in environmental reservoirs, and the ineffectiveness of current antifungal treatments. Fungal infections continue to be largely excluded from AMR initiatives while causing over 1.6 million deaths ...
