We use a 3-D finite difference numerical model to generate synthetic seismograms from a simple fractured reservoir containing evenly-spaced, discrete, vertical fracture zones. The fracture zones are represented using a single column of anisotropic grid points. In our experiments, we vary the spacing of the fracture zones from 10-meters to 100-meters, corresponding to fracture density values fro...

Tetraodon palustris, new species, is described from the Mekong basin of Thailand. Tetraodon palustris differs from T cochinchinensis and T. fangi in having no ocellus on the flank and spinules dorsally from the interorbital region to the end of the dorsal-fin base. T. etraodon cochinchinensis is distinguished from T. fangi by having a longer snout (43.5-49.2% HL in T. cochinchinensis vs. 37.9-4...

AIMS To compare complications associated with dorsal percutaneous and limited dorsal approaches in the surgical treatment of fractured scaphoid bone. METHODS A total of 51 patients with acute type A2, B2 and B3 scaphoid fractures were treated by limited dorsal approach. During follow-up examinations we analysed the functional outcome and per- and post-operative complications, and we compared ...

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% lignoca...

Purpose: Understanding the configuration and characteristics of comminuted fifth metacarpal neck fractures is essential for successful operative treatment, especially antegrade intramedullary Kirchner wire (K-wire) fixation. This study aimed to investigate shape fragments in suggest appropriate K-wire position.Methods: Forty-one cases operated from January 2010 April 2022 were enrolled this stu...

motor vehicle and falling down are responsible for the most number of traumatic injuries. this study aimed to compare the characteristics of traumatic brain injury among accident and falling down cases. in this analytical cross- sectional study, data were collected from the records of cadavers who died due to accident or falling down and referred to kahrizak dissection hall, tehran forensic med...

PURPOSE Complications in metacarpal fracture treatment increase in proportion to the severity of the initial injury and the invasiveness of the surgical fixation technique. This manuscript evaluates the feasibility of minimizing internal fixation construct size and soft tissue dissection, while preserving the advantages of stable internal fixation in a biomechanical model. We hypothesized that ...
