Effect of dressing with form grinding wheel on grinding surface integrity of 18CrNiMo7-6 steel
In order to explore the influence of dressing process parameters, such as dressing depth ad, axial feed speed fd and dressing speed ratio qd, on the grinding surface integrity of 18CrNiMo7-6 gear steel, orthogonal experiments were conducted for shaping ...

Preparation and properties of intermetallic-bonded diamond grinding wheel for thinning SiC wafer
Objectives: Compared with Si-based materials, SiC has become an ideal substrate material for chip manufacturing due to its good thermal conductivity, high breakdown electric field strength, and large bandgap width. However, the Mohs hardness of SiC wafer

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

Refining techniques for high‐frequency monitoring of chlorophyll a fluorescence in estuarine systems
Abstract Concentrations of the photosynthetic pigment chlorophyll a are commonly used as a proxy for phytoplankton biomass in aquatic systems. Traditional methods for extracting chlorophyll a in discrete samples limit measurement frequency, while in situ sensor technology provides high frequency chlorophyll a fluorescence measurements at a more ...

Abstract Advances in DNA technology have significantly enhanced the forensic community's ability to develop genetic profiles from unidentified human skeletal remains. However, sampling requires mechanical grinding of hard tissues before DNA isolation. This processing can compromise genetic profiles, particularly in aged bones.
