[null,null,null,"Sommario/riassunto","This book examines developments in governance reform in Britain, with a particular focus on the period since 2010. We argue that the experiences of the past decade mean that public value-based ideas are required to inform governance reform for the coming years. This needs to be prioritised due to the twin challenges of managing the aftermath of Brexit and navigating through the recovery phase of the COVID-19 pandemic. The volume outlines key themes, issues and debates relevant to contemporary public sector reform including: modes of state governance, evidence-based policy-making debates, the challenges and possibilities of public sector innovation, accountability issues, and the implications of Brexit. The overall conclusion of the book is that the coming decade presents an opportunity for more paradigmatic changes to UK governance but, for this to happen, "]
[{"$nulls":4},"political leaders need to prioritise a ‘reinventing government’ agenda underpinned by public value-based thinking and approaches. This book will be of particular interest to students of politics and public administration and relevant for those with general research interests in British governance and public policy.

The book reviews the physical and chemical aspects of grease lubrication, primarily directed towards lubrication of rolling bearings.The first part of the book covers grease composition, properties and rheology, including thermal and dynamics properties. Later chapters cover the dynamics of greased bearings, including grease life, bearing life, reliability and testing. The final chapter covers lubrications systems - the systems that deliver grease to the components requiring lubrication.Grease Lubrication in Rolling Bearings:  Describes the underlying physical and chemical properties of grease.  Discusses the effect of load, speed, temperature, bearing geometry, bearing materials and grease type on bearing wear.  Covers both bearing and grease performance, including thermo-mechanical ageing and testing methodologies.  It is intended for researchers and engineers in the petro-chemical and bearing industry, industries related to this (e.g. wind turbine industry, automotive industry) and for application engineers. It will also be of interest for teaching in post-graduate courses\"--"]
