Planar hydraulic fracture growth perpendicular to the isotropy plane in a transversely isotropic material

Brice Tanguy Alphonse Lecampion, Haseeb Zia, Fatima-Ezzahra Moukhtari

The configuration of a hydraulic fracture (HF) propagating perpendicular to the isotropy plane of a transversely isotropic (TI) material is encountered in most sedimentary basins. We account for both elastic and fracture toughness anisotropy, and investiga ...

Curable filler material for tubular structures

Andreas Schmocker

A radiopaque composition with low viscosity and increased photopolymerizability for application or filling of hollow structures is disclosed. Moreover, a method to apply and monitor the application and/or the photopolymerization of the composition are pres ...

Impact of the anisotropy of fracture toughness on the propagation of planar 3D hydraulic fracture

Brice Tanguy Alphonse Lecampion, Haseeb Zia

Sedimentary rocks often exhibit a transverse isotropy due to fine scale layering. We investigate the effect of the anisotropy of fracture toughness on the propagation of a planar 3D hydraulic fracture perpendicular to the isotropy plane: a configuration co ...

Molecular dynamics simulations of the intrinsically disordered protein amelogenin

John Christopher Plummer, Matteo Gregorio Modesto Marascio, Alessandra Apicella

Amelogenin refers to a class of intrinsically disordered proteins that are the major constituents of enamel matrix derivative (EMD), an extract of porcine fetal teeth used in regenerative periodontal therapy. Modifications in molecular conformation induced ...

Strontium hydroxyapatite and strontium carbonate as templates for the precipitation of calcium-phosphates in the absence and presence of fluoride

Janet Gordon Hering, Michèle Bernadette Heeb

The heterogeneous precipitation of calcium phosphates on calcium hydroxyapariLe (Ca-10(PO4)(4)OH)(2) or HAP) in the presence arid absence of fluoride is important in the formation of bone and teeth, protection against tooth decay, dental and skeletal fluor ...

Detection and Strain Typing of Ancient Mycobacterium leprae from a Medieval Leprosy Hospital

Stewart Cole, Pushpendra Singh

Nine burials excavated from the Magdalen Hill Archaeological Research Project (MHARP) in Winchester, UK, showing skeletal signs of lepromatous leprosy (LL) have been studied using a multidisciplinary approach including osteological, geochemical and biomole ...

Dental Phenotype in Jalili Syndrome Due to a c.1312 dupC Homozygous Mutation in the CNNM4 Gene

Jalili syndrome denotes a recessively inherited combination of an eye disease (cone-rod dystrophy) and a dental disorder (amelogenesis imperfecta), which is caused by mutations in the CNNM4 gene. Whereas the ophthalmic consequences of these mutations have ...

Uptake of Fluoride from Aqueous Solution on Nano-Sized Hydroxyapatite: Examination of a Fluoridated Surface Layer

Janet Gordon Hering

Hydroxyapatite (Ca-10(PO4)(6)(OH)(2), HAP), both as a synthetic material and as a constituent of bone char, can serve as an effective and relatively inexpensive filter material for fluoride (F-) removal from drinking water in low-income countries. Fluoride ...

Immobilizing device for a toothed wheel

Simon Nessim Henein, Fabiano Colpo

The invention relates to an immobilizing device for a toothed wheel suitable for the field of horology where it can be part of a direct- or indirect-impulse escapement, in particular in a wristwatch. This immobilizing device (1, 2, 3, 4, 5, 6) comprises: — ...

Three-dimensional morphometry of strained bovine periodontal ligament using synchrotron radiation-based tomography

John Botsis, Joël Cugnoni, Marzio Bergomi

The periodontal ligament (PDL) is a highly vascularized soft connective tissue. Previous studies suggest that the viscous component of the mechanical response may be explained by the deformation-induced collapse and expansion of internal voids (i.e. chiefl ...

Experimental and numerical investigations on the fluid contribution to the tensile-compressive mechanical behavior of the bovine periodontal ligament

Marzio Bergomi

Orthodontic treatments are all based on the experimental evidence that teeth can be forced to move in the dental arch by means of applied mechanical forces. Since it allows for prediction of dental mobility, the mechanical characterization of the tissues i ...

An exact formula for "tooth-to-tooth" permeance

Yves Perriard, Marcel Jufer, Miroslav Markovic

We present a new, completely original exact method to determine the permeance between two opposing iron teeth. This configuration is important because it is often encountered in electrical machines and apparatus. The method is based on conformal mapping. T ...

Determination of tooth cogging force in a hard-disk brushless DC motor

Yves Perriard, Marcel Jufer, Miroslav Markovic

The paper proposes a new method to determine the tooth cogging force in a brushless DC (BLDC) motor which is used in a hard-disk application. This force might be a source of tooth vibrations and motor noise. In the new method, the permanent-magnet (PM) pol ...

With applications to the periodontal ligament: a nonlinear large strain viscoelastic law

Jörn Justiz

The soft tissue, called periodontal ligament (PDL), that connects the alveolar bone and the tooth root accounts to a large extent for the mobility, stress-distribution and, due to its viscoelastic properties, damping of the bone-tooth complex. The accurate ...
