Blast Resilience of Glazed Façades: Towards a New Understanding of the Post-Fracture Behaviour of Laminated Glass
… both provide residual resistance, following the fracture of the glass layers, and retain glass fragments. Therefore, such panels can act as the first barrier of defence during an external explosion to prevent the blast waves from penetrating the building interior and protect occupants. The blast …

MUSCULOSKELETAL STRENGTH, FALL AND FRACTURE RISK IN EARLY POSTMENOPAUSAL WOMEN
… over the first year following a distal radius fracture (DRF), and evaluate differences in fall and fracture risk factors in women over the age of 50 years with a DRF compared to their non-fractured peers. Methods: Two cohorts of participants volunteered in two sub-studies of the thesis. The …

Using HR-pQCT and finite element analysis to inform clinical assessment of distal radius fractures
Distal radius fractures (DRFs) are commonly treated non-operatively with cast immobilization; however, there are no standardized clinical practice guidelines to direct optimal duration of immobilization following a DRF. Finite element (FE) modelling coupled with high-resolution peripheral …

Η ΕΠΙΔΡΑΣΗ ΤΗΣ ΧΡΟΝΙΑΣ ΧΟΡΗΓΗΣΗΣ ΔΙΦΑΙΝΥΛΟΔΑΝΤΟΙΝΗΣ ΣΤΗΝ ΠΩΡΩΣΗ ΠΡΟΚΛΗΤΩΝ ΚΑΤΑΓΜΑΤΩΝ ΤΗΣ ΚΑΤΩ ΓΝΑΘΟΥ ΕΠΙΜΥΩΝ
… ON THE PROCESS OF HEALING OF MANDIBULAR FRACTURES IN YOUNG RATS. FOR THIS PURPOSE 45 FEMALE WISTARRATS WERE USED SEPARATED IN THREE GROUPS OF 15 RATS EACH. TWO OF THESE GROUPS CONSISTED FROM THE EXPERIMENTAL ANIMALS WHILE THE THIRD ONE INCLUDED THE CONTROL ANIMALS. THE CHRONIC …

Comparison of Additively Manufactured and Wrought 17-4 PH Stainless Steels in Ultra Low Cycle Fatigue
… between the AM and wrought specimens, post fracture microstructure, fractography, surface hardness, and material characterizations are conducted. Results indicate reduced fatigue life for AM 17-4PH stainless steel as compared to the wrought counterparts. Fatigue life reductions of 62% …

A variable capacitor made from single crystal silicon fracture surface pairs
… applied load to a notched specimen region pre-.fracture and acts as a precision bearing post-fracture. When material is not ejected, crystalline silicon's extreme brittleness at room temperature results in complementary fracture surfaces; "closed" gaps of 20-30 nanometers are typical. …

… ESTROGENS' INFLUENCE ON THE HEALING PROCESS OF FRACTURES WAS THEIR KNOWN CONTRIBUTION TO THE RESTRAINT OF THE OSTEOLYTIC PROCESSWHICH OCCURS IN OSTEOPOROSIS. FRACTURES WERE EXPERIMENTALLY CAUSED TO THE ANGLE OF THE MANDIBLE OF 63 FEMALE WISTAR RATS. TWENTY ONE OF THE ANIMALS COMPOSED THE CONTROL …

Characterization of the microstructural properties that are predictive of regain in strength in phosphate-deficient mice
Fracture healing occurs in a discrete set of steps, which recapitulates embryonic endochondral bone formation. Pathophysiologies of the fracture healing that prolong the fracture repair or result in non-union may be associated with either environmental or congenital deficiencies. Phosphate …

A Randomized Controlled Trial Comparing Contrast Baths to Cryotherapy in Patients with a Wrist Fracture
… Participants were recruited after a period of post-fracture immobilization. Blind assessors attained measurements in range of motion, pain, and edema in the 1st, 2nd, and 4th weeks. Participants were randomly assigned to either use cryotherapy or contrast baths at home during the 4-week study …

Applications of Continuous Wavelet Transform in Hydraulic Fracturing and Reservoir Management
… of Continuous Wavelet Transform (CWT) in fracture diagnostics and reservoir management, offering an in-depth analysis of various methods and their effectiveness. It addresses key aspects of hydraulic fracturing diagnostics, including fracture closure identification, dynamic fracture event …

Determinants of Nonrecovery Following Hip Fracture in Older Adults: a Chronic Disease Trajectory Analysis
Hip fracture in older adults may be the sentinel event leading to functional decline, long-term disability, and death. For the substantial number of older persons who fracture a hip each year, the chances of full functional recovery remains relatively low. The purpose of this study was to examine …

Cortical Reorganisation in Complex Regional Pain Syndrome (CRPS)
… of unknown aetiology, usually occurring post-traumatically. Early diagnosis of CRPS remains a challenge with adverse implications on rehabilitation and recovery. The main goals of my research were to help develop clinically useful bedside tests as well as objective biomarkers to improve …

Cortical thickness estimation of the proximal femur from multi-view dual-energy X-ray absorptiometry
Hip fracture is the leading cause of acute orthopaedic hospital admission amongst the elderly, with around a third of patients not surviving one-year post-fracture. Current risk assessment tools ignore cortical bone thinning, a focal structural defect characterizing hip fragility. Cortical …

Effects of Binge Alcohol Exposure on Canonical Wnt Signaling During Fracture Repair
… alcohol consumption is associated with increased fracture risk, delayed bone healing and fracture non-union. Binge alcohol consumption has occurred in 25-40% of all orthopaedic trauma cases. The canonical Wnt pathway, through tight regulation of stabilized beta-catenin, plays an essential and …

Redundancy Evaluation of Fracture Critical Bridges
Cases of brittle fractures in major bridges prompted AASHTO to publish its first fracture control plan in 1978. It focused on material and fabrication standards, and required periodic 24-month hands-on inspection of bridges with fracture critical members. The practical result of this plan was to …

DEVELOPMENT AND APPLICATION OF SMART CARBON-BASED COATINGS FOR MULTIFUNCTIONAL SENSING OF CEMENTITIOUS STRUCTURES
… gauges, with partial electrical recovery post-fracture. Polymeric coatings with 0.5 wt% CNT achieved a 309 gauge factor across a wide strain range (0 - 165 με), while higher dosage increased sensitivity but reduced operational intervals. Nanoscale lattice modelling confirmed that high …
