Horizontal drilling and multistage hydraulic fracturing have seen widespread application in shale formations during the past decade, leading to significant
[L.fractura, a break] 1. An injury that upon assessment is painful, swollen, and deformed. 2. A break of a bone. TYPES OF FRACTURES CAUSES Fractures may be due to pathologies, direct or indirect violence, or muscular contraction. In a pathological fracture, bones break, spontaneously and ...
2. A break of a bone. TYPES OF FRACTURES CAUSESFractures may be due to pathologies, direct or indirect violence, or muscular contraction. In a pathological fracture, bones break, spontaneously and without trauma, due to certain diseases and conditions like cancer, osteomalacia, syphilis, and ...
fracture,break- breaking of hard tissue such as bone; "it was a nasty fracture"; "the break seems to have been caused by a fall" greenstick fracture- a partial fracture of a bone (usually in children); the bone is bent but broken on only one side ...
The patients were also compared to a completely separate control group of 200 patients of the same age without a history of femoral fracture. Previous or current bisphosphonate use was assessed by examination of the computerized medication list and confirmed by contacting the patient or their ...
Later, Clarkson and Williams-Kovacs, (2013)a divided the flowback process into before-breakthrough (BBT) and after-breakthrough (ABT) according to the time when gas enters the fracture from matrix. During BBT, only single-phase water flows in fracture. When it comes to ABT, formation gas ...
A greenstick fracture describes the situation when the bone partially breaks. This often occurs in infants and children where the bone hasn't completely calcified and has the potential to bend instead of breaking completely through. It is similar to trying to break off a young branch or shoot ...
Such soft and hard dual networks enhance the mechanical performance of SHPAAc-[Fe.sup.3+] hydrogels greatly and in a synergistic manner [25], The optimal SHPAAc-[Fe.sup.3+] hydrogel had excellent tensile strength and elongation at break, exhibited 100% rapid recovery of elastic modulus, fr...
The process of “double-cup” fracture was examined in vacuum melted copper round bar specimens pulled in tension and compared with that of “cup and cone” fracture in a previous paper.Longitudinal sections of specimens strained to various points on the load vs elongation curve were examined by...
The fractured surfaces include a lot of useful information that can help investigate the reasons that caused metal materials to break. For example, the details on the processes that lead to failure can be determined from these surfaces, making it useful to investigate their morphology. The principl...
