Introduction: Voyager and Galileo showed that the surface of Europa has undergone significant reworking at some point during the moon’s history. The surface is covered in lineaments, which likely formed from the tides generated from Europa’s eccentric orbit around Jupiter [1]. There is also a relative paucity of visible impact craters, suggesting a surface age of about 80 million years [2]. The...

hoffa fracture is a rare injury consisting of unicondylar tangential posterior fracture of the distal femur and only very few cases have been reported in the literature. these fractures are due to high energy trauma and conservative treatment generally yields poor results, but rigid internal fixation allows early functional rehabilitation and decreases the incidence of complications. the purpos...

To characterize the hydraulic fracture network of a conglomerate reservoir, slant core well was drilled aimed to obtain direct information regarding fractures through at fracturing test site (CHFTS). Core classification fundamental issue project. In this study, three grade classifications for were proposed. Comprehensive carried out using analytic hierarchy process (AHP)–fuzzy comprehensive eva...

Background and Aim: Despite the advances in maxillofacial surgery, impaired bone healing remains a concern for surgical teams. Effects of sildenafil and pentoxifylline on healing of bone fractures have not been well investigated. This study aimed to assess the effects of sildenafil and pentoxifylline phosphodiesterase inhibitors on healing of mandibular fractures in rats. Materials and Methods...

Correspondence to: Lai-Wa Kwok Abstract: Glucocorticoid-induced osteoporosis is the most common cause of drug-induced osteoporosis, leading to fragility fractures, decrease in mobility and quality of life. Patients who receive equivalent dose of prednisolone 5 mg for more than six months are at risk of glucocorticoid-induced osteoporosis, but there is no conclusive evidence for a safe cutoff fo...

Natural fractures act as critical flow channels and reservoir space in the Lucaogou Formation tight of Jimsar Sag. It is essential to identify main controlling factors natural order achieve efficient development oil this area. There are mainly three types fractures, including tectonic diagenetic abnormal overpressure-induced fractures. Diagenetic predominantly bedding seams. The fracture affect...

Abstract Fractures contribute to bulk elastic anisotropy of many materials in the Earth. This includes glaciers and ice sheets, whose fracture state controls routing water base thus large-scale flow. Here we use anisotropy-induced shear wave splitting characterize structure probe subsurface drainage beneath a seismometer network on an Alpine glacier. Shear observations reveal diurnal variations...

Outcrop studies have revealed the presence of abundant cemented fractures in many low permeable formations. Recovered cores have also revealed the opening of some of these smaller size fractures on the wall surface of main hydraulic fractures. Furthermore, earlyproduction well-testing analysis in some of these cases provide estimates for hydraulically induced fracture surface areas which are mu...
