In this investigation ‚the fracture toughness of A356 containing15%SiC composite was studied. Al/SiC composites have been considered because of their mechanical and erosion properties .Low fracture toughness in Al/SiC as compared with Aluminium alloys is one of its disadvantage. In this study at first A356 alloy was melted in a smelting electrical furnace then poured into the mould. A356-15% Si...

BACKGROUND The objective of this study was to determine whether one can achieve stable fixation of a two column (transverse) acetabular fracture by only fixing a single column with a locking plate and unicortical locking screws. We hypothesized that a locking plate applied to the anterior column of a transverse acetabular fracture would create a construct that is more rigid than a non-locking p...

The use of the visible implant elastomer (VIE) tagging system in zebrafish (Danio rerio) was examined. Two tag orientations (horizontal and vertical) at the dorsal fin base were tested for tag retention, tag fragmentation and whether VIE tags affected growth and survival of juvenile zebrafish (1-4 month post hatch). Six tag locations (abdomen, anal fin base, caudal peduncle, dorsal fin base, pe...

We report a rare case of dislocation of second to fourth carpometacarpal (CMC) joints of the right hand with combined dorsal and ulnarward displacement of the second to fourth digits and fracture of the shaft of the first metacarpal associated with degloving injury. These injuries were diagnosed early and treated successfully with closed reduction and internal fixation using Kirschner wires. Th...

BACKGROUND The mechanical response of the spinal cord during burst fracture was seldom quantitatively addressed and only few studies look into the internal strain of the white and grey matters within the spinal cord during thoracolumbar burst fracture (TLBF). The aim of the study is to investigate the mechanical response of the spinal cord during TLBF and correlate the percent canal compromise ...

INTRODUCTION Penile fracture is the most common presentation of acute penis. Rupture of the superficial dorsal penile vein (s) may mimic penile fractures with similar clinical presentation but with intact corporeal bodies. Our aim of the study is to highlight superficial dorsal penile vein (s) injury as true emergency with better prognosis. SUBJECTS AND METHODS Sixty-eight patients with suspe...

ABSTRACT BACKGROUND Although fractures of the distal radius are a common clinical presentation, many factors affect instability of these injuries. The aim of this study was to assess the influence of age, sex, distal radial ulnar joint injury (DRUJ), ulnar styloid fracture, and dorsal displacement in late collapse of distal radius fractures. METHODS Three hundred twenty-nine patient fractu...

background digital nerve block is commonly performed by care providers in medical fields. this study compares the blocks in terms of effectiveness of anesthesia and pain. methods patients were divided into two groups. first group underwent digital block whereas 2nd group had transmetacarpal digital block. the subcutaneous ring block was performed by two injections of 3 ml of 2% lignocaine in a ...

A case of isolated dorsal midtarsal (Chopart) dislocation resulting from blunt trauma is reported. The mechanism of injury, management, and long-term outcome are discussed. A 45-year-old inebriated man fell from a 4-m height and landed on his feet. He had immediate bilateral foot and back pain. Radiographs showed a burst fracture of the second lumbar vertebra, a left Pott's fracture, and an iso...

A new species of dart fish, Parioglossus galzini sp. nov., is described based on specimens collected in Haurei Bay, Rapa Island (French Polynesia). It is distinguished from all other described species of Parioglossus as follows: dark lateral body stripe absent, 100 or more scales in longitudinal series from above pectoral-fin base to base of caudal fin, pectoral-fin rays 19–21, membrane of firs...
