Widows' Breath: Grief Fractures
… true story” applies to this collection of grief fractures. Each is based on a thread of someone’s true story of death and loss. A combination of autobiographic fiction and speculative non-fiction, these fractures create a thematic braiding of grief as they explore the human survival of …

Velocity profile in confined elliptic fractures
The primary objective of this research is to determine the friction inside a smooth fracture and to incorporate the effect of friction on a fluid transient inside a tapered-elliptical-confined fracture. In order to do so, the non-uniform velocity profile in an elliptic fracture with laminar flow of …

Laser induced fractures in porous media.
… evaluate the feasibility of using laser-induced fractures as an alternative technique, an analytical model has been developed to calculate temperature distribution during the laser fracturing method. The novelty of the developed model lies in incorporating melting and vaporisation of rock …

Rib stress fractures in elite rowers
… the development of exercise-induced rib stress fractures (RSF) in elite rowers as well as investigate biomechanical and neuromuscular differences of ergometer rowing in stationary and slide-based ergometers. BMD and muscle strength was assessed as well as EMG of thoracic muscles and rowing …

Scaphoid Fractures - epidemiology, diagnosis and treatment.
… to prolonged union or non-union of scaphoid fractures. Finally, we evaluated time-to-union of scaphoid waist fractures treated conservatively or by arthroscopy-assisted surgery. In the two diagnostic studies on adults and paediatric patients (paper I-II) 390 wrists were enrolled for MRI …

Epiphyseal fractures of the distal humerus
… injuries in children, i.e. lateral condylar fractures, medial condylar fractures, fracture-separation of the distal humeral epiphysis and T-condylar fractures. Medial and lateral epicondylar fractures, being apophyseal, are excluded. The research was done at the Red Cross Children's Hospital …

Conceptual models of fluid flow in fractures
… thesis is titled "CONCEPTUAL MODELS OF FLOW IN FRACTURES". This thesis study has two parts. In the first part, some conceptual models of fluid flow in fractures will be developed. These models will be used to analyze fluid flow in the near field region of nuclear waste canisters emplaced in …

The growth of fractures in the Earth
… case, when compression is large. Right-stepping fractures under a left-lateral shearing run away from each other when their centers are more than one fracture length distant; when this is not the case, they turn toward each other. Interaction is thus significant only in this last case. …

Epidemiology and Biomechanical Analysis of Facial Fractures
… is to examine the occurrence of facial fractures in automotive collisions and to determine the tolerance of the facial bones to blunt impact. The effects of restraint use, impact severity and impact direction on facial fractures were evaluated using the NASS-CDS database. The association …

Nanoparticle Transport Through Fractures And Heterogeneous Porous Media
… degree to which subsurface flow occurs through fractures and high permeable zones in heterogeneous porous media. Using carbon based 2-5 nm particles (C-Dots); we inject dual tracers at different flow rates into a permeable core channel (fracture). The KBr tracer has time to diffuse into the …

Effects of thermally-induced fractures on EGS performance
… thermo-elastic stresses that triggers thermal fractures. Initially, when the induced temperature gradient is critically high, a thermally-shocked region comprising a network of small, disorganized, closely-spaced thermal cracks is formed adjacent to the primary hydraulic fractures. These small …

Investigation of spine loading to understand vertebral fractures
Vertebral fractures are the most common complication of osteoporosis and are associated with significant pain, height loss, disfigurement, respiratory impairment, depression, and decreased life span. Despite the high personal and societal costs of vertebral fractures, little is known regarding …

Do anatomical contoured plates address scapula body, neck, and glenoid fractures and can these fractures be classified? – A multi-observer consensus study
… management of scapula body, neck and glenoid fractures remains a challenge. This study focusses on templating an available anatomical pre-contoured plating system using 3D printed scapulae to assess the ability of these plates to address the aforementioned fractures and to determine consensus …

Propagation of fluid driven fractures in transversely isotropic material
The propagation of fluid driven fractures is used in a number of industrial applications (well stimulation of unconventional reservoirs, development of deep geothermal systems) but also occurs naturally (magmatic dyke intrusion). While the mechanics of hydraulic fractures (HF) in isotropic media is …

Immediate versus delayed surgical management of septic mandibular fractures
… delayed surgical management of septic mandibular fractures. Introduction: Infected mandible fractures can be treated via diverse protocols. Two recognized protocols are the so-called delayed approached and the immediate approach. In the delayed approach, sepsis is resolved first, followed by …

Characterization of Fractures Subjected to Normal and Shear Stress
… to shear as well as normal stress. Synthetic fractures made of gypsum and lucite were prepared with different fracture surface conditions: either well-mated or non-mated. For well-mated fracture surfaces, asperities were created by casting gypsum against sandpaper. A block of gypsum was cast …

Hip fracture - Mortality and residual lifetime risk of fractures
… and the subsequent shorter time at risk of new fractures, almost half of all female and almost one third of all male patients suffered at least one new fracture after the hip fracture. Women more often fractured on multiple occasions. The 10-year mortality-adjusted risk of new fractures was 40% …
