Abstract Enhanced geothermal systems (EGS) offer the potential for a much larger energy source than conventional hydrothermal systems. Hot, low-permeability rocks are prevalent at depth around world, but challenge of extracting thermal depends on ability to create and sustain open fracture networks. Laboratory experiments were conducted using suite selected rock cores (granite, metasediment, rh...

INTRODUCTION A great number of studies performed in the last 3 decades have shown the superior mechanical features of nickel-titanium files as compared with stainless steel files. A novel file system recently developed, Gentlefile, defies these findings and claims to have superior qualities despite the fact it is made from stainless steel. METHODS Three file systems were used in this experime...

Introduction Seismic anisotropy is often explained in terms of effective media where an ordered ensemble of sub-seismic elements leads to a directional variation of the materials properties. Examples of such systems include aligned cracks or fractures, fine layering and correlated pore space. Therefore, measurements of seismic anisotropy potentially allow insights to physical systems which woul...

Classifi cation systems have been introduced for a variety of orthopedic conditions over the years, and for many of them—including fractures—several systems have been suggested. More comprehensive classifi cation systems are useful for pooling of data from publications over time, to compare data in different publications. Also, systematic reviews would benefi t greatly from a uniformity in term...

Background: Osteoporosis is a common condition among the elderly population, and is associated with an increased risk of fracture. One of the most common fragility fractures involve the distal radius, and are associated with risk of subsequent fragility fracture. Early treatment with bisphosphonates has been suggested to decrease the population hip fracture burden. However, there have been no p...

conclusions closed reduction and hybrid external fixation can be used as a definitive treatment for severe comminuted fractures of the distal femur and proximal tibia, when the concomitant contusion of the skin and soft tissue damage prohibits safe open reduction and internal fixation. patients and methods in a prospective study, 44 patients with comminuted fractures of the distal femur or prox...

background: considering the importance of an early diagnosis and proper decision-making in regards to the treatment of pediatric distal radius and elbow fractures, this study examines emergency medicine specialists’ accuracy in the diagnosis and treatment of these patients. methods: from 2012 and 2013, children less than 14 years old who were referred to an academic hospital emergency departmen...
