Making Mining Licit: Gold, Commodification, and the Everyday Performance of Law in Colombia

American Anthropologist, EarlyView.
ABSTRACT Ethnographies of resource‐making have shown that the extraction of resource value from objects is premised on obviating the emplaced lifeworlds that surrounded objects before they traveled to consumer markets. Much of this literature looks at such supply‐chain disentanglement from the viewpoint of corporate and formal regulatory practices ...

Effects of Dietary Activated Charcoal Supplementation on Performance, Egg Quality, and Bone Calcification in Laying Hens Exposed to High Fluoride

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT The aim of the present study was to determine the effects of high dietary fluoride intake on performance, egg quality, serum biochemical parameters, bone tissue, mineral accumulation, and the expression of selected mineralisation‐related genes in laying hens, and to evaluate whether these effects could be alleviated by dietary activated ...

Engineering Biofunctional Tantalum Implants Through Surface Functionalization for Infection‐Resistant Bone Regeneration

Small Structures
Tantalum has emerged as a promising metallic biomaterial for orthopedic implants owing to its excellent biocompatibility, corrosion resistance, and mechanical compatibility with bone tissue, particularly in porous architectures.

X-ray Induced Electric Currents in Anodized Ta₂O₅: Towards a Large-Area Thin-Film Sensor

Sensors
Purpose: We investigated the characteristics of radiation-induced current in nano-porous pellet and thin-film anodized tantalum exposed to kVp X-ray beams. We aim at developing a large area (≫cm2) thin-film radiation sensor for medical, national security

Characteristics of bone ingrowth and interface mechanics of a new porous tantalum biomaterial

, 1999
We have studied the characteristics of bone ingrowth of a new porous tantalum biomaterial in a simple transcortical canine model using cylindrical implants 5 × 10 mm in size.

Computed tomography evaluation of the periacetabular gap of a porous tantalum acetabular component [PDF]

, 2019
2019-02The periacetabular gap is an inherent consequence of the peripheral rim press-fit of the porous tantalum acetabular component. The circumference of the prosthesis is clearly depicted with computed tomography (CT) images that have been optimised to

Engineered surface strategies to manage dental implant‐related infections

Periodontology 2000, EarlyView.
Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.
