Hierarchically Rough rGO/HAp Nanocoatings on SLM Ti–6Al–4 V Implants for Enhanced Biointegration

Small, EarlyView.
This study investigates HAp/rGO bioactive coatings on Ti‐6Al‐4V fixation implants fabricated by selective laser melting with systematically varied volumetric energy density to tailor the as‐built surface state. Composite coatings were deposited by electrophoretic deposition and characterized using micro‐CT, profilometry, FESEM/EDS, and detailed XPS to ...

Patrones en las excursiones de swash en dos playas contrastantes: Playas Hollywood y Costa Verde, Colombia

Dyna, 2018
La zona de swash es la parte de la playa que esta consecutivamente seca y húmeda debido al ascenso y descenso del mar producto del oleaje y la marea. Esta zona es de gran importancia en los sistemas de playas, ya que allí se desarrollan los procesos de ...

Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

steel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

Experimental Investigation of Electrical Parameter Effects in Wire Arc Atomization of 316L Stainless Steel Powders for Additive Manufacturing

steel research international, EarlyView.
This article presents wire arc atomization of 316L for the production of metallic powders used in additive manufacturing, with a systematic analysis of the influence of arc parameters on particle size. Through the application of dry sieving, scanning electron microscopy, and shape analysis, it is demonstrated that this technique is well‐suited for ...

Lidar Observations of the Swash Zone of a Low-Tide Terraced Tropical Beach under Variable Wave Conditions: The Nha Trang (Vietnam) COASTVAR Experiment

Journal of Marine Science and Engineering, 2020
A field experiment was conducted at a tropical microtidal intermediate sandy beach with a low tide terrace (Nha Trang, Vietnam) to investigate the short-term swash-zone hydrodynamics and morphodynamics under variable wave conditions.

Masculinity, Prostitution, and the Imaginary Northwest in Chinese Travel Writings About Shanxi and Western Inner Mongolia, 1920–1949

Gender &History, EarlyView.
ABSTRACT This article considers travel writings by metropolitan men in Republican China about Shanxi and western Inner Mongolia as a case study to further explore the transformations and continuities of Chinese masculinities. Drawing upon a range of popular travel narratives, it shows that so‐called “Worn‐Out Shoes (poxie)” – women perceived as ...

Swash-flow induced forces on human body standing on a smooth and impermeable slope: A numerical study with experimental validations

Engineering Applications of Computational Fluid Mechanics
Swash flow poses a significant hazard to pedestrians standing on the slope of the seawall. Unlike the forces of overtopping flow or open channel flow on the human body, which have been studied before, swash flow has two distinct cycles within one wave ...

Swash on Steep and Shallow Beaches

Coastal Engineering 1984, 1984
Extensive field observations of swash on natural beaches are used to relate the magnitudes of swash oscillations to incident wave conditions and the beach slope. Swash fluctuations at wind wave frequencies (defined here as f > .05 Hz) appear to be "saturated." As in laboratory experiments with monochromatic waves, wave breaking prevents the ...

Area of origin analysis for expirated patterns using HemoVision

Journal of Forensic Sciences, EarlyView.
Abstract Although bloodstain pattern analysis (BPA) can be performed on various types of patterns, there is a lack of research looking into whether the area of origin (AO) can be determined for expirated patterns. Expirated patterns are formed when blood is pushed out of an opening in the body by the force of air, in some cases forming a pattern of ...

Cliff Notching Due To Swash Abrasion: Insights From Physical Experiments

Geophysical Research Letters
Notch development at the base of sea cliffs is an important control on cliff recession rates, but a detailed mechanistic understanding of notch formation by swash abrasion is lacking.
