Who won Britain’s culture wars? The urban left’s mixed success

Although often ridiculed in the 1980s, the left’s social policies were on the winning side when it came to gender, sexuality, and environmentalism, writes James Curran. However, the same cannot be said for their politics of race, and certainly not for their economic policies

Prime labelings on planar grid graphs

It is known that for any prime p and any integer n such that 1≤n≤p there exists a prime labeling on the pxn planar grid graph PpxPn. We show that PpxPn has a prime labeling for any odd prime p and any integer n such that that p\u3cn≤p2

Optimized scheduling of water distribution network to reduce energy costs

Energy costs for water utilities have increased significantly over recent years, primarily due to expanding water supply systems and increases in electricity charges. The impact of rising energy costs is being felt by Rous County Council (Rous Water) who own and operate the bulk water supply system for the Northern Rivers region in NSW. There is currently a strong drive within Council to reduce our energy costs. This dissertation investigates options to reduce energy costs of the bulk water supply system owned and operated by Rous Water. The focus of this dissertation is on controlling the filling schedule of the reservoirs in the water distribution network to enable the high energy demand Nightcap Water Treatment Plant (WTP) to take advantage of Time of Use (TOU) electricity metering. Investigation of current energy usage identified a number of possible control options to schedule the operation of the WTP into lower cost electricity tariff periods. The control options to schedule operation of the water distribution network were developed using the existing functionality of the SCADA control system to minimise costs. Modelling of the control options was able to demonstrate that the avoidance of peak tariff energy use can be achieved with only minor modifications to the SCADA control system. The estimated energy cost savings from the implementation of this project recommendations are approximately 10% of Council’s total energy costs. This dissertation has shown that there are significant savings available for water utilities by taking advantage of TOU electricity tariff structures. Scheduling the operation of high energy demand equipment into less expensive tariff periods can be achieved using existing SCADA based control systems

On-road emissions evaluation of student-produced biodiesel

UT Biodiesel is a small scale, student run Used Frying Oil (UFO) to biodiesel production program at the University of Tennessee, Knoxville. A single batch transesterification reaction using methanol and potassium hydroxide (KOH) as the catalyst is used to produce biodiesel from UFO collected from UT Dining Services. A warm deionized water wash is used to remove contaminants from the biodiesel. A heat and settle method is used to dry the biodiesel. The processor has been shown to be capable of producing fuel that meets the ASTM D6751 specification for biodiesel. The project uses in-house testing to ensure the quality of the fuel. In-house tests include methanol content, water content, total glycerin, and acid number. This study evaluates the on-road emissions of the student-produced biodiesel in a modern diesel vehicle. The test vehicle is powered by a GM 1.9 liter direct injected turbo diesel using cooled EGR. The vehicle is equipped with a diesel oxidation catalyst and a diesel particulate filter. An Autologic five gas analyzer was used to evaluate tailpipe emissions on a prescribed driving cycle. An Autologic heavy duty smoke meter was used to evaluate smoke opacity using a stationary test. Biodiesel blends of B20 and B50 were evaluated against ultra low sulfur diesel fuel (ULSD) and neat biodiesel, B100

Fuel Economy and Greenhouse Gas Reduction Potentials of Advanced Combustion Modes in Light-Duty Vehicles: A Well-to-Wheel Analysis using Vehicle Systems Simulations with Experimental Engine Data

Vehicle fuel efficiency and emissions regulations are driving a radical shift in the need for high efficiency powertrains along with control of criteria air pollutants and greenhouse gases. High efficiency powertrains including vehicle electrification, engine downsizing, and advanced combustion concepts all seek to accomplish these goals. Homogeneous charge compression ignition (HCCI) concepts have been proposed have not been able to demonstrate the controllability to operate over a sufficient engine speed and load range to make it practical for implementation in production vehicles. In-cylinder blending of gasoline and diesel to achieve reactivity controlled compression ignition (RCCI) has been shown to reduce NOX and PM emissions while maintaining or improving brake thermal efficiency as compared to conventional diesel combustion (CDC). The RCCI concept has an advantage over many advanced combustion strategies in that the fuel reactivity can be tailored to the engine speed and load allowing stable low-temperature combustion to be extended over more of the light-duty drive cycle load range. The potential for advanced combustion concepts such as RCCI to reduce drive cycle fuel economy and emissions is not clearly understood and is explored in this research by simulating the fuel economy and emissions for a multi-mode RCCI-enabled vehicle operating over a variety of U.S. drive cycles using experimental engine maps for multi-mode RCCI, CDC and a 2009 port-fuel injected (PFI) gasoline engine. Simulations are completed assuming a conventional mid-size passenger vehicle with an automatic transmission. RCCI fuel economy simulation results are compared to the same vehicle powered by a representative 2009 PFI gasoline engine over multiple drive cycles Engine-out drive cycle emissions are compared to CDC and observations regarding relative gasoline and diesel tank sizes needed for the various drive cycles are also summarized. The well-to-wheel energy and greenhouse gas emissions from these drive cycle simulations running carious amounts of biofuels are examined and compared to the state-of-the art in conventional, electric and hybrid powertrains

Introduction

It might seem strange to devote a collection of essays to Shakespeare and Phenomenology in the second decade of the twenty-first century. After all, phenomenology as a philosophical movement had its heyday in the middle of the twentieth century. But phenomenology\u27s demise as a major philosophical movement has enabled it to live on as the approach or method shorn of dogma that its earliest practitioners promised. Far from being a single school of thought, phenomenology now looks more like an intellectual diaspora, a galaxy of related but discreet propositions that share basic assumptions while pursuing different philosophical projects. In early modern and Shakespeare studies, we have seen a particularly robust variant of phenomenology in the past ten years in the practice of historical phenomenology. In this special issue, we attempt to build on the successes of historical phenomenology by pursuing a variety of phenomenological approaches and practices in relation to Shakespeare and the early modern. By embracing phenomenology\u27s remarkable intellectual diaspora, we hope to offer a new critical agenda for phenomenologically inflected reading of Shakespeare. We propose that phenomenology offers a language of speculation and inquiry dynamic enough to accommodate both historicism and theory, a common language that can speak as compellingly to questions of law, ethics, performance, and hospitality as it can to questions about feeling and sensation. Accordingly, Shakespeare and Phenomenology is not invested in carving out yet another subfield of Shakespeare studies. On the contrary, in this collection we are committed to opening up conversations among subfields and to imagining a common critical future

Culture Wars: the media and the left in Britain, 2nd edition

Culture Wars investigates the relationship between the media and politics in Britain today. It focusses on how significant sections of the national press have represented and distorted the policies of the Labour Party, and particularly its left, from the Thatcher era up to and including Ed Miliband’s and Jeremy Corbyn’s leaderships. Revised and updated, including five brand new chapters, this second edition shows how press hostility to the left, particularly newspaper coverage of its policies on race, gender and sexuality, has morphed into a more generalised campaign against ‘political correctness’, the ‘liberal elite’ and the so-called ‘enemies of the people’. Combining fine-grained case studies with authoritative overviews of recent British political and media history, Culture Wars demonstrates how much of the press have routinely attacked Labour and, in so doing, have abused their political power, distorted public debate and negatively impacted the news agendas of public service broadcasters. The book also raises the intriguing question of whether the rise of social media, and the success of its initial exploitation by Corbyn supporters, followed by Labour as a whole in the 2017 General Election, represent a major shift in the balance of power between Labour and the media, and in particular the right-wing press
