CONSULTANCY STATE: Government as (a) Service and the Anti‐politics of Technological Expertise in Indian Cities

International Journal of Urban and Regional Research, EarlyView.
Abstract This article analyses ideas of ‘good governance through technology’ in India that first emerged from the software industry, symbolizing state support for the ‘new middle‐class’ values of liberalized private enterprise. We suggest that the contemporary prominence of consulting firms in government represents a second transformation that embeds ...

Effect of Kinematics and Speed on Filling Material Removal, Canal Transportation, and Apical Extrusion During Retreatment of Curved Canals

Australian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated the effects of kinematics (reciprocating vs. continuous rotation) and rotational speed (350 vs. 1200 rpm) on filling removal, canal transportation, and apical extrusion during retreatment of curved root canals. Vertucci type II mesial roots of mandibular molars were prepared, filled, and scanned by micro‐computed ...

Factors Associated With Endodontic Flare‐Ups: A Systematic Review and Meta‐Analysis

International Endodontic Journal, EarlyView.
ABSTRACT Background Endodontic flare‐ups, characterized by severe postoperative pain and/or swelling requiring unscheduled intervention, remain a clinically significant concern in root canal therapy. Identifying the factors associated with flare‐ups is important for anticipating and managing patient outcomes.

Microstructure and Martensitic Transformation Behaviors of Explosively Welded NiTi/NiTi Laminates

Chinese Journal of Aeronautics, 2007
AbstractThe study is a first attempt to prepare bulk NiTi/NiTi shape memory alloy (SMA) laminates with a macroscopic heterogeneous composition by explosive welding and investigate their microstructures and martensitic transformation behaviors. After explosive welding, a perfect interfacial bonding between the two components and a reversible martensitic

Outcomes of Root Canal Treatment in Patients With Autoimmune Disease: A Retrospective Case–Control Study

International Endodontic Journal, EarlyView.
ABSTRACT Aim The purpose of this study was to compare the outcome of nonsurgical root canal treatment (RCT) in patients with autoimmune diseases (AD) with the outcome in patients without AD. The null hypothesis was: there is no difference in the outcomes of RCT regardless of the patient group. Results were also compared among AD subgroups: inflammatory

Nanoprecipitate characterisation in NiTi and aluminium alloys: A TEM‐based overview

Journal of Microscopy, EarlyView.
Abstract Nanoscale precipitates are central to the functional and mechanical performance of many advanced alloys, yet their characteristics and spatial distributions can be directly resolved only by electron microscopy. In this poster‐style article, focused ion beam‐prepared TEM lamellae are used to provide a microscopy‐focused overview of ...
