The development of low-cost, highly active, and stable oxygen reduction reaction (ORR) catalysts is of great weboost splitter importance for practical applications in numerous energy conversion devices.Herein, iron/nitrogen/phosphorus co-doped carbon electrocatalysts (NPFe-C) with multistage porous structure were synthesized by the self-template me
Colonoscopy continues to evolve as equipment and techniques improve.Traditionally, colonoscopy has focused on adenoma detection, characterisation and resection as the primary aims, and there has certainly been considerable activity over the last few years in click here terms of addressing these important issues.This review article not only will dis
ObjectivesAs a closed gathering place, prison is the cradle of tuberculosis (TB) outbreak.Therefore, the analysis of the prevalence rate and risk factors of latent tuberculosis infection (LTBI) in prison will be a necessary measure to intervene in the spread of tuberculosis.MethodsIn this study, we consecutively recruited 506 adult prisoners in Qin
Objective: Investigate the patterns of facial fractures presenting to an oral and maxillofacial service at a teaching hospital in Trinidad.Methods: A retrospective study was conducted to obtain information on traumatic maxillofacial and mandibular fractures from the Oral and Maxillofacial unit at the Eric Williams Medical Complex, Trinidad.Data was
The histogram location approach has been proposed by Kahn (1997) to estimate the fraction of wage cuts prevented by downward nominal wage rigidity.In this paper, we analyze the validity of the approach by means of a simulation study which yielded apunisw2 evidence of unbiasedness but also of potential underestimation of rigidity parameter uncertain
