Geologic heterogeneity is one of the important factors controlling migration and distribution nonaqueous phase liquids in subsurface. Heterogeneity, such as fractures, complicates effectiveness environmental remediation, uncharacterized aquifer causes significant uncertainties removal liquids. Foaming an injection gas effective method to alleviate challenges accessing heterogeneous media during...
Introdouction: The incidence and etiology of maxillofacial fractures are influenced by social, cultural, and environmental factors. Understanding the cause, severity, and temporal distribution of maxillofacial trauma provides an insight into the behavioral patterns of people from different countries and can also assist in establishing clinical and research priorities for effective treatment and...
Background and Aim: Applying Ilizarov fixator is an easier method compared with other methods in treating of tibial fractures. But it be used less frequently than others yet, little information about it is available .The present study was performed to evaluate the results and complications of Ilizarov external fixator in type 3C Pilon fractures. Materials and Methods: In this retrospective stud...
this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...
Background: Respiratory problems are common after long bone fractures. The objective of the present investigation is to evaluate the effect of early fixation of femoral shaft fracture on the incidence of respiratory problems. Methods: The results of early and late stabilization of femoral shaft fractures were studied in 150 patients. The patients were divided into two groups according to the st...
Background: Conventional fixation methods of posterior wall acetabular fractures feature the use of plating and lagscrews. However, fixation of posterior wall fractures with buttress plating alone offers potential advantages by avoidingthe hardware complications related to hardware placement through the wall fragment. The purpose of this study wasto examine if buttress plating...
