Effects of Cutting Insert Flank Wear in Previous Turning and Subsequent Diamond Burnishing on the Surface Integrity, Microstructure and Fatigue Limit of Heat-Treated C45 Steel

open access: yesMetals
Burnishing technologies are a cheap and effective means of improving the surface integrity (SI) and performance of metal components. However, there is practically no information about the integral influence of the preceding turning process on the initial

Determination of absolute tool wear by γ-γ coincidence counting of radiotracers

open access: yes
γ-γ coincidence methods have been applied to obtain absolute flank and crater wear volumes from irradiated high speed steel (HSS) tools using 60Co as the radiotracer. Consistent absolute results can be obtained irrespective of the exact counting geometry

A new, conspicuously pigmented Pyrrhulina (Teleostei: Characiformes: Lebiasinidae) from the Río Tigre, Loreto, Peru

open access: yesJournal of Fish Biology, EarlyView.
Abstract A new species of Pyrrhulina is described based on morphological and molecular evidence. Pyrrhulina punctata is distinguished from all congeners by the presence of a series of 7 to 16 irregular blotches of dark pigmentation on the flanks, equally marked in juveniles and adult specimens, the presence of 26–28 lateral‐line scales, 17–21 maxillary

The Effect of Drill Flank-Wear on the Cutting Resistance

open access: yes, 1981
본 논문에서는 drill의 측면마모가 torque와 thrust에 미치는 영향에 관해서 연구하였다. 측면마모의 주절삭날에 따른 분포를 2차원 절삭에 적용되는 Taylor's too-life equation을 이용해서 ??로 가정하고 torque와 thrust에 관한 식을 유도하였다. 그 결과 wear land가 4.2×10??인치 정도에 도달했을 때 flank wear에 의한 torque와 thrust가 전체 torque와 thrust에 각각 약 10%

Tooth morphology of deep‐water catsharks of the genus Apristurus (Chondrichthyes: Pentanchidae) in the North Atlantic Ocean

open access: yesJournal of Fish Biology, EarlyView.
Abstract The deep‐water catshark family (Pentanchidae) is the most species‐rich family among extant shark lineages. Within this family, the genus Apristurus is the largest, comprising small, deep‐sea species characterised by elongated bodies and dorso‐ventrally compressed snouts. Five Apristurus species are currently recognised from the North Atlantic,

High‐quality genome of elite peanut cultivar ZH05 reveals subgenome asymmetry, pan‐genome diversity, and breeding insights

open access: yesJournal of Integrative Plant Biology, EarlyView.
A high‐quality reference genome for the elite peanut cultivar Zhonghua No. 5 revealed differing evolutionary paths between the two peanut subgenomes. SubA has higher overall gene expression and more open chromatin, whereas SubB has stronger structural organization, higher DNA methylation, and greater adaptive diversity associated with peanut evolution ...

Flank Wear Estimation in Turning Through Wavelet Representation of Acoustic Emission Signals

open access: yes, 1997
This paper investigates a flank wear estimation technique in turning through wavelet representation of acoustic emission (AE) signals. It is known that the power spectral density of AE signals in turning is sensitive to gradually increasing flank wear ...

Palaces for a New Spain Nobility: Between Creole Identity and Academicism

open access: yesSociology Lens, Volume 38, Issue 1, Page 75-86, March 2025.
ABSTRACT Mexico City and Havana had a significant number of noble palaces during the eighteenth century. Until now, the dearth of historical documentation on their construction has hampered any approximation, requiring other methodologies. Here, it is intended to establish how a new visual code was defined, consistent both with their local style and ...

Barley HvBODYGUARD1 controls cuticular specialisations regulated by SHINE transcription factors

open access: yesNew Phytologist, EarlyView.
Cuticle defects result from defective HvBDG1 alleles. Summary Land plants secrete a protective outer cuticular layer with diverse functions. Barley (Hordeum vulgare L.) develops two cuticular specialisations: the β‐diketone rich wax bloom on vegetative tissues and an adherent grain surface which sticks to the hulls, leading to barley's distinctive ...
