  2. London, England

    2003-01-01

    For almost 2,000 years, the River Thames has served as the life force of London, capital of the United Kingdom and one of the world's most famous cities. In AD 43 the Romans established the trading settlement of Londinium at a favorable crossing point on the river. The Romans remained until the 5th century, when the city came under Saxon control. The early 17th century saw enormous growth, but the deadly plague of 1664 and 1665 ravaged the population, and in the following year the Great Fire, which burned for four days, destroyed most of the city. A public transportation system and other city services in the early 19th century eased many of the increasing urban problems of the burgeoning capital of the wealthy British Empire. After coping with the devastating effects of bombing during World War II and the gradual dismantling of the empire, London today thrives as a vital modern metropolis. London is one of 100 cities being studied using ASTER data to map and monitor urban use patterns and growth.

    This image was acquired on October 12, 2001 by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet.

    ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products.

    The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping, and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats

  12. Looking into 'London'

    NASA Technical Reports Server (NTRS)

    2004-01-01

    This mosaic image from the microscopic imager on the Mars Exploration Rover Opportunity shows the rock abrasion tool target, 'London.' The image was taken by the Mars Exploration Rover Opportunity on its 149th sol on Mars (June 24, 2004). Scientists 'read' the geology of the image from bottom to top, with the youngest material pictured at the bottom of the image and the oldest material in the layers pictured at the top. Millimeter-scale layers run horizontally across the exposed surface, with two sliced sphere-like objects, or 'blueberries' on the upper left and upper right sides of the impression. This material is similar to the evaporative material found in 'Eagle Crater.' However, the intense review of these layers in Endurance Crater is, in essence, deepening the water story authored by ancient Mars.

    In Eagle Crater, the effects of water were traced down a matter of centimeters. Endurance Crater's depth has allowed the tracing of water's telltale marks up to meters. Another process that significantly affects martian terrain is muddying the water story a bit. Although it is clear that the layers in Endurance were affected by water, it is also evident that Aeolian, or wind, processes have contributed to the makeup of the crater.

  13. Eye casualty services in London

    Smith, H B; Daniel, C S; Verma, S

    2013-01-01

    The combined pressures of the European Working Time Directive, 4 h waiting time target, and growing rates of unplanned hospital attendances have forced a major consolidation of eye casualty departments across the country, with the remaining units seeing a rapid increase in demand. We examine the effect of these changes on the provision of emergency eye care in Central London, and see what wider lessons can be learned. We surveyed the managers responsible for each of London's 8 out-of-hours eye casualty services, analysed data on attendance numbers, and conducted detailed interviews with lead clinicians. At London's two largest units, Moorfields Eye Hospital and the Western Eye Hospital, annual attendance numbers have been rising at 7.9% per year (to 76 034 patients in 2010/11) and 9.6% per year (to 31 128 patients in 2010/11), respectively. Using Moorfields as a case study, we discuss methods to increase capacity and efficiency in response to this demand, and also examine some of the unintended consequences of service consolidation including patients travelling long distances to geographically inappropriate units, and confusion over responsibility for out-of-hours inpatient cover. We describe a novel ‘referral pathway' developed to minimise unnecessary travelling and delay for patients, and propose a forum for the strategic planning of London's eye casualty services in the future.

  15. Low on the London Scale

    NASA Astrophysics Data System (ADS)

    Webb, S.

    2013-09-01

    Until relatively recently, many authors have assumed that if extraterrestrial life is discovered it will be via the discovery of extraterrestrial intelligence: we can best try to detect life by adopting the SETI approach of trying to detect beacons or artefacts. The Rio Scale, proposed by Almár and Tarter in 2000, is a tool for quantifying the potential significance for society of any such reported detection. However, improvements in technology and advances in astrobiology raise the possibility that the discovery of extraterrestrial life will instead be via the detection of atmospheric biosignatures. The London Scale, proposed by Almár in 2010, attempts to quantify the potential significance of the discovery of extraterrestrial life rather than extraterrestrial intelligence. What might be the consequences of the announcement of a discovery that ranks low on the London Scale? In other words, what might be society's reaction if 'first contact' is via the remote sensing of the byproducts of unicellular organisms rather than with the products of high intelligence? Here, I examine some possible reactions to that question; in particular, I discuss how such an announcement might affect our views of life here on Earth and of humanity's place in the universe.

  20. Fritz London's Legacy at Duke University

    NASA Astrophysics Data System (ADS)

    Meyer, Horst

    2006-03-01

    When 3He became available in small quantities after WWII Fritz London, Professor at Duke University since 1939, became very interested in its properties in the liquid and solid phases, as contrasted with those of 4He. His influence and that of his colleague Walter Gordy led to the appointment of William Fairbank in 1952, who was able to verify experimentally the prediction on the Fermi degeneracy of liquid 3He below 1K, a few weeks before London's death in 1954. With his students and associates, Fairbank carried out a number of important experiments which became classics, several of which will be described. At Duke he also started planning other experiments inspired by London's predictions. After W. Fairbank's departure for Stanford in 1959, further research on liquid and solid 3He and 3He-4He mixtures was carried out by his successors at Duke University and some of the results in the sixties will be briefly described.

  1. Suicide on the London Underground System.

    Farmer, R; O'Donnell, I; Tranah, T

    1991-09-01

    Over the past 50 years there has been an increase in the numbers of people jumping/falling in front of trains on the London Underground system. Case-fatality rates have fallen from 70% in the 1950s to 55% today. The proportion certified as suicide has fallen while the proportions certified as accidents or open verdicts have risen. There is unusual clustering of events at some stations which are adjacent to psychiatric units. The hypothesis that ease of access to London Underground stations may sometimes be a determinant of suicide is investigated. PMID:1955255

  2. Are Londoners Prepared for an Emergency? A Longitudinal Study Following the London Bombings

    PubMed Central

    Rubin, James; Amlôt, Richard; Simpson, John; Wessely, Simon

    2008-01-01

    The UK government sees increasing individual preparedness as a priority, but the level of preparedness of people in the UK for a large-scale emergency is not known. The London bombings of July 7, 2005, affected many Londoners and may have altered their sense of vulnerability to a future terrorist attack. We used a longitudinal study design to assess individual preparedness within the same sample of Londoners at 2 points in time: immediately after the bombings (T1) and 7 to 8 months later (T2). A demographically representative sample of 1,010 Londoners participated in a phone interview at T1. Subsequently, at T2, 574 of the same people participated in a follow-up phone interview. At T1 51% of Londoners had made 4 or more relevant emergency plans; 48% had gathered 4 or more relevant supplies in case of emergency. There was evidence of increased preparedness at T2, by which time 90% had made 4 or more emergency plans. Ethnicity, low social status, and having felt a sense of threat during the bombings predicted increased preparedness between T1 and T2. Women in general, and women of low social status in particular, perceived themselves to be unprepared in the event of a future terrorist attack. In summary, Londoners show moderate levels of emergency preparedness, which increased following the London bombings. Although we cannot know whether this association is causal, the prospective nature of the study increases the likelihood that it is. However, preparedness is still patchy, and there are important demographic associations with levels of preparedness and perception of vulnerability. These findings have implications for future development of individual and community emergency preparedness policy. PMID:19117430

The goal of the meeting was to provide delegates with an update of recent advances in management of pregnancy-related conditions, to present research data and to discuss the current attitudes and practices in relevant topics. An extensive range of topics were discussed, from preeclampsia and treatment of hypertension, to the psychological impact of termination of pregnancy and feticide. This report will summarize a selection of the lectures presented. PMID:26900652

  4. Presence of Legionella in London's water supplies.

    PubMed

    Colbourne, J S; Trew, R M

    1986-09-01

    Legionella occurs frequently (52 to 54%) in domestic water and cooling water inside commercial, industrial and health care buildings, and these types of water systems are now regarded as a normal habitat for Legionella. The factors that predispose a particular water system to colonization by these organisms are ill-defined, although it is fairly certain that biological and physicochemical environmental factors play an important role in allowing Legionella to multiply in the circulating water. It has been postulated that the organism may gain access to water systems inside buildings by one of three routes: contact with air through open points such as uncovered storage tanks or vents, ingress of soil or surface water during construction or repair, or intermittent seeding with organisms present in low numbers in the public water supply. Three studies in the USA have found Legionella in 0.4 to 8.8% of drinking-water samples, but these were not representative of the public supply network as a whole. The aim of this study was to determine, over a period of 1 year, the frequency of Legionella in London's drinking water--from the treatment plant through to the consumer's tap. To date, Legionella has not been isolated from raw river water entering London's treatment works or from treated water entering the distribution network. Sixty-two monitoring taps in buildings located in 21 supply areas have been sampled twice for Legionella; only 2 (2.4%) have proved positive during the autumn and winter of 1985/86. The strain found was L. pneumophila serotype 1, subgroup Olda, and the numbers ranged from 10(2) to 10(4)/l. Although the survey is incomplete, it is already clear that the public water supplies in London are not a source of strains of Legionella associated with disease. PMID:3793445

    Se presenta un mapa geologico digital de Venezuela sobre un fondo de relieve sombreado. Los datos geologicos e hidrologicos del norte del rio Orinoco proceden de la digitalizacion de mapas geologicos en papel a escala 1:500.000. Estos datos fueron integrados con el mapa geologico digital del Escudo de Guayana Venezolano, a su vez derivado de hojas en papel a escala 1:500.000. La informacion sobre los tipos de fallas mostrados en el mapa es igual que en las fuentes originales. Los poligonos geologicos fueron atribuidos por edad, litologia y nombre de la unidad siguiendo el Codigo geologico de Venezuela. Se incorporaron revisiones significativas de la geologia de la Cordillera de la Costa a partir de las nuevas hojas integradas a escala 1:25.000. Toda esta informacion geologico-estructural se sobrepuso a una imagen de relieve sombreado, producida por el procesamiento de los datos de radar interferometrico con 90 m (3 arcosegundos) de resolucion espacial obtenidos por la mision topografica de radar del transbordador espacial (SRTM). Las areas de la base de datos del SRTM carentes de informacion fueron llenadas por medio de la interpolacion de los datos de las celdas adyacentes. Para producir la imagen de relieve sombreado se uso una direccion de iluminacion de 315 deg con un angulo de 65 deg sobre el horizonte. La proyeccion usada en el mapa es conica equidistante, con latitudes de 4 y 9 deg norte como paralelos estandar y una longitud de 66 deg al oeste como meridiano central. Los datos en el mapa proceden primordialment de hojas a escala 1:500.000 y el producto esta preparado para una impresion optima en escala 1:750.000. Los usuarios pueden obtener ampliaciones mayores, sin embargo no se garantiza la precision del mapa a escalas mas detalladas. Especialmente en la region de Guayana, al sobreponer los mapas geologicos sobre la reciente imagen SRTM, se notan grandes discrepancias no sistematicas tanto en contactos como en fallas. Esto es debido a que los mapas

    The Society of Apothecaries is both a City livery company and an examining authority for the medical profession. Founded in 1617 by the royal apothecary Gideon de Laune leading a breakaway group from the Grocers' Company, the Society was instrumental in raising the status of apothecaries as general practitioners. Under the Apothecaries' Act (1815) the Society examined for the LSA and it now awards the LMSSA (Licence in Medicine and Surgery of the Society of Apothecaries) and postgraduate diplomas, while maintaining the civic, charitable, and ceremonial traditions of a livery company of the City of London.

    On February 4, 2008, the world's largest low emission zone (LEZ) was established. At 2644 km2, the zone encompasses most of Greater London. It restricts the entry of the oldest and most polluting diesel vehicles, including heavy-goods vehicles (haulage trucks), buses and coaches, larger vans, and minibuses. It does not apply to cars or motorcycles. The LEZ scheme will introduce increasingly stringent Euro emissions standards over time. The creation of this zone presented a unique opportunity to estimate the effects of a stepwise reduction in vehicle emissions on air quality and health. Before undertaking such an investigation, robust baseline data were gathered on air quality and the oxidative activity and metal content of particulate matter (PM) from air pollution monitors located in Greater London. In addition, methods were developed for using databases of electronic primary-care records in order to evaluate the zone's health effects. Our study began in 2007, using information about the planned restrictions in an agreed-upon LEZ scenario and year-on-year changes in the vehicle fleet in models to predict air pollution concentrations in London for the years 2005, 2008, and 2010. Based on this detailed emissions and air pollution modeling, the areas in London were then identified that were expected to show the greatest changes in air pollution concentrations and population exposures after the implementation of the LEZ. Using these predictions, the best placement of a pollution monitoring network was determined and the feasibility of evaluating the health effects using electronic primary-care records was assessed. To measure baseline pollutant concentrations before the implementation of the LEZ, a comprehensive monitoring network was established close to major roadways and intersections. Output-difference plots from statistical modeling for 2010 indicated seven key areas likely to experience the greatest change in concentrations of nitrogen dioxide (NO2) (at least 3

    Aims Prescribing for athletes requires an up-to-date knowledge of the World Anti-Doping Agency's list of prohibited substances. As the London 2012 Olympic Games attract athletes from around the world, we review the current guidelines with respect to all medications licensed for ophthalmic use in the United Kingdom. We describe the process that an ophthalmologist can use to check for permissible medications and also highlight treatments that are contraindicated. Methods We systematically reviewed all 77 drugs listed in Section 11 of the British National Formulary (Issue 63) for use in the treatment of ophthalmic conditions, and referenced these against the 2012 Prohibited List published by the World Anti-Doping Agency. Results The majority of ophthalmic preparations are suitable for use in- and out-of-competition. Some preparations, such as glucocorticoids, are prohibited when administered systemically but permitted for topical administration. Beta-blockers are prohibited in-competition and oral carbonic anhydrase inhibitors are prohibited in- and out-of competition. Conclusion The 2012 Prohibited List has important implications for the pharmacological treatment of ophthalmic conditions in athletes. Clinicians prescribing for athletes have a duty to familiarise themselves with the list in order to avoid causing significant damage to their patient's career and reputation. PMID:22744394

    2011-01-01

    A review of evidence on infant mortality derived from the London bills of mortality and parish registers indicates that there were major registration problems throughout the whole of the parish register period. One way of addressing these problems is to carry out reconstitution studies of individual London parishes, but there are a number of problems with reconstitution methodology, including the traffic in corpses between parishes both inside and outside of London and the negligence of clergymen in registering both baptisms and burials. In this paper the triangulation of sources has been employed to measure the adequacy of burial registration, including the comparison of data from bills of mortality, parish registers and probate returns, as well as the use of the same-name technique. This research indicates that between 20 and 40 per cent of burials went unregistered in London during the parish register period. PMID:22397160

    2011-01-01

    It takes a few millimetres of rainfall to cause the 34 most polluting combined sewer overflows (CSOs) to discharge into the River Thames. Currently, in a typical year, spillages to the tidal reaches of the River Thames occur about 60 times, with an estimated spill volume of 39 million cubic metres. Both the UK Government and the European Union have determined that the CSO discharges have an adverse environmental impact on fish species, introduce unacceptable aesthetics and elevate the health risks for recreational users of the Thames, with a frequency of discharge which is in breach of the Urban Wastewater Treatment Directive. Studies have established that the environmental objectives can be fully met on the most cost-effective basis by completing both quality improvements to treatment works and by the provision of a storage and transfer tunnel to intercept unsatisfactory CSOs. Extensive modelling has been undertaken to develop an optimised solution. In parallel with the design development a rigorous and comprehensive site selection methodology has been established to select sites and consult stakeholders and the public on the preferred sites and scheme, with the first stage of public consultation planned for later in 2010. The London Tideway Tunnels are an essential part of the delivery of improvements to the water quality of the tidal River Thames, and this ambitious, historic scheme represents a vital strategic investment in London's infrastructure.

    We perform a multifractal analysis of the evolution of London's street network from 1786 to 2010. First, we show that a single fractal dimension, commonly associated with the morphological description of cities, does not suffice to capture the dynamics of the system. Instead, for a proper characterization of such a dynamics, the multifractal spectrum needs to be considered. Our analysis reveals that London evolves from an inhomogeneous fractal structure, which can be described in terms of a multifractal, to a homogeneous one, which converges to monofractality. We argue that London's multifractal to monofractal evolution might be a special outcome of the constraint imposed on its growth by a green belt. Through a series of simulations, we show that multifractal objects, constructed through diffusion limited aggregation, evolve toward monofractality if their growth is constrained by a nonpermeable boundary.

    1994-02-01

    A database containing details of every incident of suicidal behaviour on the London Underground railway system between 1940 and 1990 was assembled from the records of London Underground Ltd and the British Transport Police. The total number of cases was 3240. The mean annual number of suicidal acts on the London Underground system increased from 36.1 (1940-1949) to 94.1 (1980-1989). There were significantly fewer incidents on Sundays than on the other days of the week and the daily rate was highest in the spring. 64% of incidents involved males and the peak age group for both sexes was 25-34 yr. Suicide verdicts were returned for a greater proportion of women than men. Overall case fatality was 55%. However, case fatality rates differed between stations, environmental factors appearing to influence survival. Possible strategies to prevent railway suicides and reduce the lethality of this method are discussed. PMID:8153744

  7. Sources and contributions of wood smoke during winter in London

    Determining the contribution of wood smoke in large urban centres such as London is becoming increasingly important with the changing nature of domestic heating partly due to the installation of biomass burning heaters to meet renewable energy targets imposed by the EU and also a rise in so-called recreational burning for aesthetic reasons (Fuller et al., 2013). Recent work in large urban centres (London, Paris and Berlin) has demonstrated an increase in the contribution of wood smoke to ambient particles during winter that can at times exceed traffic emissions. In Europe, biomass burning has been identified as a major cause of exceedances of European air quality limits during winter (Fuller et al., 2013). In light of the changing nature of emissions in urban areas there is a need for on-going measurements to assess the impact of biomass burning in cities like London. Therefore we aimed to determine quantitatively the contribution of biomass burning in London and surrounding rural areas. We also aimed to determine whether local emissions or regional sources were the main source of biomass burning in London. Sources of wood smoke during winter in London were investigated at an urban background site (North Kensington) and two surrounding rural sites (Harwell and Detling) by analysing selected wood smoke chemical tracers. Concentrations of levoglucosan, elemental carbon (EC), organic carbon (OC) and K+ were generally well correlated, indicating a similar source of these species at the three sites. Based on the conversion factor for levoglucosan, mean wood smoke mass at Detling, North Kensington and Harwell was 0.78, 0.87 and 1.0 µg m-3, respectively. At all the sites, biomass burning was found to be a source of OC and EC, with the largest source of OC and EC found to be secondary organic aerosols and traffic emissions, respectively. Peaks in levoglucosan concentrations at the sites were observed to coincide with low ambient temperature, suggesting domestic heating as

    This article offers an examination of the patterns and motivations behind parish apprenticeship in late eighteenth- and early nineteenth-century London. It stresses continuity in outlook from parish officials binding children, which involved placements in both the traditional and industrializing sectors of the economy. Evidence on the ages, employment types, and locations of 3,285 pauper apprentices bound from different parts of London between 1767 and 1833 indicates a variety of local patterns. The analysis reveals a pattern of youthful age at binding, a range of employment experiences, and parish-specific links to particular trades and manufactures. PMID:20939134

  9. Fisica a escala de Planck usando o principio de incerteza generalizado: efeitos nas flutuações primordiais e buracos negros

    2003-08-01

    Em escalas proximas à escala de Planck todas as teorias perturbativas de cordas produzem essenciamente a mesma relação de conmutação entre as coordenadas e impulsos (a chamada "álgebra deformada"), permitindo assim estudar a física resultante independentemente dos detalhes da teoria de cordas que seja considerada correta. Este resultado completamente geral, que inclui as interações gravitacionais junto com o resto dos campos pode ser considerada uma versão generalizada (GUP) do Princípio de Incerteza de Heisenberg. Aplicamos neste trabalho essas relações de conmutação para dois sistemas físicos bem definidos: buracos negros de massas próximas à massa de Planck, e flutuações quânticas em pequenas escalas antes do universo sofrer inflação. Obtemos dois resultados concretos dos efeitos do GUP : o primeiro é que o GUP impede a evaporação completa de buracos negros microscópicos na extensão do formalismo semiclássico, deixando assim remanescentes de pequena massa que já foram postulados como candidatos a matéria escura. O segundo resultado é o 'smoothing' das flutuações primordiais em pequenas escalas que levariam à produção de buracos negros primordiais após a inflação, impedindo assim a produção abundante destes últimos e predizendo abundancias atuais bem menores do que os limites disponíveis. Concluimos que, analogamente a utilização do Princípio de Incerteza de Heisenberg para estudar e determinar propriedades fundamentais das interações sem gravitação, o GUP e uma ferramenta poderosa para estudar uma ampla variedade de sistemas trans-Planckianos e predizer seu comportamento dispensando cálculos mais detalhados proprios da teoria quântica da gravitação.

    Between 1852 and 1857 at the London Hospital, 142 amputations were performed in 136 patients. The most common indication was an injury sustained at work. Overall mortality was 46% and the death rate was especially high for lower-limb amputations. Most deaths were due to postoperative sepsis. Those who received chloroform anaesthesia did worse than those who received ether. PMID:11461989

  3. Nicholas Culpeper (1616-1654): London's first general practitioner?

    PubMed

    Farthing, Michael J G

    2015-08-01

    Nicholas Culpeper is often regarded as an ill-disciplined, maverick, mid-17th century herbalist and the father of contemporary alternative medicine. There are elements of this statement that have some truth but to dismiss his contribution to the development of health provision in London at the time would be a great injustice. Culpeper did not complete his apprenticeship as an apothecary and was not a formally trained physician, but he developed a clinical practice for the poor of London, indistinguishable from the role of the present day general practitioner. Observers at the time recognised his concern and compassion and his commitment to treat the whole patient and not just the disease. His enduring contribution was his translation from Latin of the physicians' Pharmacopoeia Londinensis which could be regarded as the first major step towards the demystification of medicine. Culpeper's London Dispensatory and the many other medical treatises that followed were affordable and widely available to the common man. Culpeper antagonised both apothecaries and physicians because he breached the regulations of the day by accepting patients directly. So perhaps Culpeper was, de facto, London's first general practitioner, at least 150 years before the role was formally recognised in the Apothecaries Act 1815. PMID:24585603

  5. Deaths of cyclists in london: trends from 1992 to 2006

    PubMed Central

    2010-01-01

    Background Cycling is an increasingly important mode of transport for environmental and health reasons. Cycling fatalities in London were previously investigated in 1994 using routinely collected data. Since then, there have been shifts in the modes of transport used, and in transport policies. We sought to replicate the previous work using data on cyclist deaths in London between 1992 and 2006, specifically investigating whether heavy goods vehicles continued to pose a threat. Methods Observational study based on analysis of time series of police road casualties data, 1992 to 2006, in London, UK. The main outcome measures were cyclists killed in road traffic collisions. Poisson regression and chi-squared test for homogeneity were used to assess time effects. Travel flow data was then used to estimate annual fatality rates per 100,000 cyclists per kilometre. Results From 1992 to 2006 there was a mean of 16 cycling fatalities per year (range 8-21). 146 deaths (60%) were in inner London and 96 in outer London. There was no evidence for a decline over time (p = 0.7) other than a pronounced dip in 2004 when there were 8 fatalities. Freight vehicles were involved in 103 of 242 (43%) of all incidents and the vehicle was making a left turn in over half of these (53%). The fatality rate ranged from 20.5 deaths in 1992 to 11.1 deaths in 2006 per 100,000 estimated cyclists per kilometre (rate ratio 0.54, 95% confidence interval 0.28 to 1.03). Conclusions There is little evidence fatality rates have fallen. Freight vehicles over 3.5 tonnes continue to present a disproportionate threat; they should be removed from urban roads and more appropriate means of delivery of essential goods found. PMID:21078190

    2013-01-01

    In August 2011, several areas of London experienced episodes of large-scale disorder, comprising looting, rioting and violence. Much subsequent discourse has questioned the adequacy of the police response, in terms of the resources available and strategies used. In this article, we present a mathematical model of the spatial development of the disorder, which can be used to examine the effect of varying policing arrangements. The model is capable of simulating the general emergent patterns of the events and focusses on three fundamental aspects: the apparently-contagious nature of participation; the distances travelled to riot locations; and the deterrent effect of policing. We demonstrate that the spatial configuration of London places some areas at naturally higher risk than others, highlighting the importance of spatial considerations when planning for such events. We also investigate the consequences of varying police numbers and reaction time, which has the potential to guide policy in this area. PMID:23425781

  15. Modelling of hydrogen infrastructure for vehicle refuelling in London

    NASA Astrophysics Data System (ADS)

    Joffe, D.; Hart, D.; Bauen, A.

    One of the principal barriers to the widespread use of hydrogen as a road transport fuel is the need for a refuelling infrastructure to be established. The lack of an adequate refuelling infrastructure would severely inhibit an uptake of hydrogen vehicles. On the other hand, without significant penetration of these vehicles, the demand for hydrogen would be insufficient to make a widespread conventional refuelling infrastructure economic. The infrastructure is likely to develop initially in cities, due to the high concentration of vehicles and the anticipated air quality benefits of a switch to hydrogen as a road transport fuel. While trial schemes such as the Clean Urban Transport for Europe (CUTE) bus project will establish initial hydrogen refuelling sites, it is not clear how a transition to a widespread refuelling infrastructure will occur. Indeed, the number of possible different ways and scales of producing and distributing hydrogen means that the possible configurations for such an infrastructure are almost endless. Imperial College London is examining transition strategies for a hydrogen infrastructure for vehicle refuelling in London under a project funded by the UK Engineering and Physical Sciences Research Council (EPSRC). Imperial has five project partners from industry and local government to assist in this study: the Greater London Authority (GLA), BP, BOC, BMW and Air Products. This paper presents initial results from technical modelling of hydrogen infrastructure technologies and how they could be deployed to provide an initial facility for the refuelling of hydrogen fuel-cell buses in London. The results suggest that the choice of H 2 production technology can have significant effects on when the infrastructure would be installed, and the timing of hydrogen production, and bus refuelling.

    The London household survey has shown that people travel and are exposed to air pollutants differently. This argues for human exposure to be based upon space-time-activity data and spatio-temporal air quality predictions. For the latter, we have demonstrated the role that dispersion models can play by using two complimentary models, KCLurban, which gives source apportionment information, and Community Multi-scale Air Quality Model (CMAQ)-urban, which predicts hourly air quality. The KCLurban model is in close agreement with observations of NO(X), NO(2) and particulate matter (PM)(10/2.5), having a small normalised mean bias (-6% to 4%) and a large Index of Agreement (0.71-0.88). The temporal trends of NO(X) from the CMAQ-urban model are also in reasonable agreement with observations. Spatially, NO(2) predictions show that within 10's of metres of major roads, concentrations can range from approximately 10-20 p.p.b. up to 70 p.p.b. and that for PM(10/2.5) central London roadside concentrations are approximately double the suburban background concentrations. Exposure to different PM sources is important and we predict that brake wear-related PM(10) concentrations are approximately eight times greater near major roads than at suburban background locations. Temporally, we have shown that average NO(X) concentrations close to roads can range by a factor of approximately six between the early morning minimum and morning rush hour maximum periods. These results present strong arguments for the hybrid exposure model under development at King's and, in future, for in-building models and a model for the London Underground. PMID:23443237

  18. Lessons for climate policy from The Great Stink of London

    NASA Astrophysics Data System (ADS)

    Skuce, A.

    2012-12-01

    A rapidly growing population and the introduction of the flush toilet in nineteenth-century London caused a crisis with sewage pollution in the River Thames (Halliday, 1999). There were decades of delays in implementing solutions owing to: inadequate governance institutions; political inertia; difficulties with financing; opposition from vested interests; scientific uncertainties; and technological challenges. Effective counter-measures were started only once the problem arose, quite literally, under the noses of parliamentarians. There are parallels, some of them pointed out earlier by Alley et al (2010), between the sewage crisis in Victorian London and the current problem with climate change. Both involve the unsustainable use of a common resource (a river, the atmosphere) for the unconstrained disposal of human waste products. Alley (2011) estimated that the costs of providing clean water and sanitation are comparable to the expected costs of reducing greenhouse gas emissions. Despite the similarities, the climate change issue is actually much more difficult because of: a) the unequal and uncertain global distribution of cause and effect; b) its long, intergenerational time lines; c) the insufficiency of adequate institutions, conventions or the tools— political, moral or economic—for tackling the climate crisis. This analysis is consistent with the model proposed by Gardiner (2011) in his book A Perfect Moral Storm. The three "storms" he identifies, the global, intergenerational and theoretical storms, combine in a powerful synergy to create a challenge of unprecedented intractability, providing opportunities for what Gardiner calls moral corruption: the obscuring of the buck-passing and procrastination that characterizes climate policy today. In Victorian London, the crucial steps to solve the sewage crises were not taken until the stench from the River Thames during the hot summer of 1858 rendered the House of Commons uninhabitable.

  1. Two daily smoke maxima in eighteenth century London air

    NASA Astrophysics Data System (ADS)

    Harrison, R. Giles

    Varied electrostatics experiments followed Benjamin Franklin's pioneering atmospheric investigations. In Knightsbridge, Central London, John Read (1726-1814) installed a sensing rod in the upper part of his house and, using a pith ball electrometer and Franklin chimes, monitored atmospheric electricity from 1789 to 1791. Atmospheric electricity is sensitive to weather and smoke pollution. In calm weather conditions, Read observed two daily electrification maxima in moderate weather, around 9 am and 7 pm. This is likely to represent a double diurnal cycle in urban smoke. Before the motor car and steam railways, one source of the double maximum smoke pattern was the daily routine of fire lighting for domestic heating.

    In this article I analyze different spatial practices related to Pentecostal healing, drawing on fieldwork with Pentecostal believers who have migrated from Ghana to London, UK. I explore the relationship between space and the manifestation of the Holy Spirit by looking at how points of contact with the divine are created in the personal life of people and at the sites where the casting out of demons takes place. Unlike in other spirit-centered healing traditions, the Christian Holy Spirit is not conceived of as embodied in specific places, but rather is spatially unbound. To manifest, however, the Holy Spirit requires specific spatial qualities and esthetics. PMID:24383751

  3. Contribution of wood burning to PM10 in London

    2014-04-01

    Ahead of measures to incentivise wood heating, the current level of wood burning in London was assessed by two tracer methods; i) a six week campaign of daily measurements of levoglucosan along a 38 km transect across the city during winter 2010, ii) a three year (2009-2011) measurement programme of black carbon and particulate matter from wood burning using differential IR and UV absorption by Aethalometer. Mean winter levoglucosan concentrations were 160 ± 17 ng m-3 in central London and 30 ± 26 ng m-3 greater in the suburbs, with good temporal correlation (r2 = 0.68-0.98) between sampling sites. Sensitivity testing found that the aethalometer wood burning tracer method was more sensitive to the assumed value of the Ångström coefficient for fossil fuel black carbon than it was to the Ångström coefficient for wood burning PM, and that the model was optimised with Ångström coefficient for fossil fuel black carbon of 0.96. The aethalometer and levoglucosan estimates of mean PM from wood burning were in good agreement during the winter campaign; 1.8 μg m-3 (levoglucosan) and 2.0 μg m-3 (aethalometer); i.e. between 7% and 9% of mean PM10 across the London transect. Analysis of wood burning tracers with respect to wind speed suggested that wood burning PM was dominated by sources within the city. Concentrations of aethalometer and levoglucosan wood burning tracers were a greatest at weekends suggesting discretionary or secondary domestic wood burning rather than wood being used as a main heating source. Aethalometer wood burning tracers suggests that the annual mean concentration of PM10 from wood burning was 1.1 μg m-3. To put this in a policy context, this PM10 from wood burning is considerably greater than the city-wide mean PM10 reduction of 0.17 μg m-3 predicted from the first two phases of the London Low Emission Zone which was introduced to reduce PM from traffic sources.

    New Zealand born, Dr. Royden McIntosh Muir, MBChB(Edin), DA(RCS&RCP), emigrated to Cape Town in 1921 having specialized in anesthesia in London after World War 1 and became one of South Africa's earliest and leading anesthesiologists. He was appointed honorary anesthetist and clinical teacher by the University of Cape Town at South Africa's first medical school in 1922, and lecturer in 1927. Aware of Cape Town's isolation at the southern tip of Africa, he undertook extensive tours studying anesthetic practice at major hospitals in London, the United States and Canada in 1933 and 1938. He became a lifelong friend of Ralph Waters in Madison, who coached him in the use of cyclopropane, and he subsequently introduced cyclopropane into England and South Africa. In the United States, he met Richard von Foregger, founder of the New York based Foregger Company, from whom he later commissioned a purpose-built anesthetic machine marketed by Foregger as "The Muir Midget." Muir was a founder member of the South African Society of Anaesthetists in 1943 and was elected as its second president the following year. Based on what he had seen in academic hospitals in the United States and England, he fought until his retirement for the improved recognition of the specialty in South Africa and the establishment of adequately staffed departments of anesthesia at teaching hospitals in that country.

    The New London Submarine Base was divided by the town boundaries of Groton to the south and Ledyard to the north in New London County, Connecticut. In 1983, the Navy identified 16 potential source areas of environmental contamination during their investigations. The submarine base was listed on the US Environmental Protection Agency's National Priorities List in August 1990 because of the potential for on-base groundwater contamination to migrate to off-base residential wells that are close to the New London Submarine Base.

    The nature and strength of intermolecular interactions are crucial to a variety of kinetic and dynamic processes at surfaces. Whereas strong chemisorption bonds are known to facilitate molecular binding, the importance of the weaker yet ubiquitous van der Waals (vdW) interactions remains elusive in most cases. Here we use first-principles calculations combined with kinetic Monte Carlo simulations to unambiguously demonstrate the vital role that vdW interactions play in molecular self-assembly, using styrene nanowire growth on silicon as a prototypical example. We find that, only when the London dispersion forces are included, accounting for the attractive parts of vdW interactions, can the effective intermolecular interaction be reversed from being repulsive to attractive. Such attractive interactions, in turn, ensure the preferred growth of long wires under physically realistic conditions as observed experimentally. We further propose a cooperative scheme, invoking the application of an electric field and the selective creation of Si dangling bonds, to drastically improve the ordered arrangement of the molecular structures. The present study represents a significant step forward in the fundamental understanding and precise control of molecular self-assembly guided by London dispersion forces.

    2012-07-01

    Crime continues to cast a shadow over citizen well-being in big cities today, while also imposing huge economic and social costs. Timely understanding of how criminality emerges and how crime patterns evolve is crucial to anticipating crime, dealing with it when it occurs and developing public confidence in the police service. Every day, about 10,000 crime incidents are reported by citizens, recorded and geo-referenced in the London Metropolitan Police Service Computer Aided Dispatch (CAD) database. The unique nature of this dataset allows the patterns to be explored at particularly fine temporal granularity and at multiple spatial resolutions. This study provides a framework for the exploratory spatio-temporal analysis of crime patterns that combines visual inquiry tools (interactive animations, space-time cubes and map matrices) with cluster analysis (spatial-temporal scan statistics and the self-organizing map). This framework is tested on the CAD dataset for the London Borough of Camden in March 2010. Patterns of crime through space and time are discovered and the clustering methods were evaluated on their ability to facilitate the discovery and interpretation of these patterns.

    In recent years, the number of Spanish-speaking Latinos in Britain and London has grown considerably. Estimates from different sources put the population in London as high as 300,000. Unfortunately, this growing ethnolinguistic group is an underresearched minority, and information of any kind is hard to come by. In this article, my aim is to…

    A existência de variações rápidas de brilho em alguns blazares é um fenômeno bem comprovado, mas até agora não sabemos ao certo quais são os mecanismos físicos envolvidos. A maior dificuldade é a ausência de observações multibanda simultâneas que poderiam fornecer vínculos aos modelos. Buscando colaborar com a discussão estudamos o comportamento de dois BL Lacs, PKS 2005-489 e PKS 2155-304, em relação à variabilidade em diversas escalas de tempo, de poucos minutos até vários meses, com observações simultâneas em seis bandas espectrais (óptico e infravermelho próximo). Para tanto dois telescópios do LNA foram utilizados em conjunto nas campanhas observacionais realizadas em 2001 e 2002, cujos resultados são apresentados aqui. As duas fontes apresentaram características bastante diferentes, inclusive em relação à existência de variabilidade nos índices espectrais. Particularmente, registramos a primeira detecção de variações em escalas de tempo da ordem de poucos minutos em PKS 2005-489, com evidências da presença de um atraso entre as curvas de luz nas bandas V e R e a variação em R ocorrendo antes (o contrário do esperado no modelo de shock-in-jet). Em PKS 2155-304 detectamos pela primeira vez variabilidade em escalas de tempo de poucos minutos no infravermelho em um AGN. As observações indicam que as variações de brilho em blazares são o resultado da ação de mais de um fenômeno, especialmente em escalas de tempo muito curtas. Alguns cenários físicos são sugeridos para explicar os resultados observacionais.

    We investigate the extent to which respondents from a general population sample in London (July-August 2011) agree or disagree with the NHS covering the healthcare costs related to five risky health behaviours: overeating, unhealthy diet, sedentary life, excess of alcohol, and smoking. For each behaviour, we also directly explore the main factors associated with the likelihood to agree or disagree. Half of the respondents (N=146) manifest agreement with the idea. Wider agreement exists for covering the costs associated smoking, heavy drinking, and sedentary lives than with overeating, or poor diets. With the exception of alcohol drinking and sedentary life, there is an almost one-to-one relationship between the agreement that the NHS should pay the healthcare costs associated with a specific behaviour, and the respondents' actual engagement in that behaviour. Those at higher risk of depending on publicly funded healthcare, are more likely to agree. PMID:24945692

    London population became increasing more diverse ethnically over the decade 2001-2011, a period when the White population declined, with many commentators suggesting that there has been 'White flight' from some districts in the face of 'invasion' by members of ethnic minority groups. To examine how extensively the city's ethnic landscape changed during that period--and whether suggestions of the operation of 'invasion and succession processes' are valid--this article reports on statistical mapping of small area data for the two censuses. The results identify clearly-defined, substantial blocks of territory within the urban residential fabric where members of each of the main census respondent self-identified ethnic groups are concentrated. These have expanded outwards, into areas from which the White population has clearly withdrawn, though in most cases the rate of cluster areal expansion has been less than the groups' numerical growth.

    Paddington Station in London, UK is a large rail terminus for long distance electric and diesel powered trains. This magnificent train shed has four arched spans and is one of the remaining structural testaments to the architect Brunel. Given the current British and European legislative requirements for intelligible speech in public buildings AMS Acoustics were engaged to design an electroacoustic solution. In this paper we will outline how the significant problems of lively natural acoustics, the high operational noise levels and the strict aesthetic constraints were addressed. The resultant design is radical, using the most recent dsp controlled line array loudspeakers. In the paper we detail the acoustic modeling undertaken to predict both even direct sound pressure level coverage and STI. Further it presents the speech intelligibility measured upon handover of the new system. The design has proved to be successful and given the nature of the space, outstanding speech intelligibility is achieved.

    London, with a population of 8.2 million, is the largest city in Europe. It is heavily built-up (typically 8% vegetation cover within the central boroughs) and boasts some of the busiest arteries in Europe despite efforts to reduce traffic in the city centre with the introduction of a congestion charging scheme in 2007. We report on two substantial pollution monitoring efforts in the heart of London between October 2006 and present. Fluxes of carbon dioxide (CO2) and water (H2O) were measured continuously by eddy-covariance in central London from October 2006 until May 2008 from a 190 m telecommunication tower (BT tower; 51° 31' 17.4'' N 0° 8' 20.04'' W). The eddy-covariance system consisted of a Gill R3-50 ultrasonic anemometer operated at 20 Hz and a LI-COR 6262 infrared gas analyser. Air was sampled 0.3 m below the sensor head of the ultrasonic anemometer - which was itself mounted on a 3 m mast to the top of a 15 m lattice tower situated on the roof of the tower (instrument head at 190 m above street level) - and pulled down 45 m of 12.7 mm OD Teflon tubing. In addition, meteorological variables (temperature, relative humidity, pressure, precipitation, wind speed and direction) were also measured with a multi-sensor (Weather Transmitter WXT510, Vaisala). Eddy-covariance measurements at the BT tower location were reinstated in July 2011 and include methane (CH4), CO2 and H2O concentrations measured by a Picarro fast methane analyser (G2301-f). CO2 emissions were found to be mainly controlled by fossil fuel combustion (e.g. traffic, commercial and domestic heating). Diurnal averages of CO2 fluxes were found to be highly correlated to traffic. However changes in heating-related natural gas consumption and, to a lesser extent, photosynthetic activity in two large city centre green spaces (Hyde Park and Regent's Park) explained the seasonal variability. Annual estimates of net exchange of CO2 obtained by eddy-covariance agreed well with up-scaled data from the UK

    For centuries, in the Eastern Mediterranean region, medicinal plant use has been widely accepted as a treatment method for both minor and major diseases. Although some knowledge exists on the use of such medicinal plants within the Greek Cypriot culture and considerable information is available on various regions in Turkey, no detailed ethnopharmaceutical or ethnobotanical studies exist on Turkish-speaking Cypriots (TSC) both in Cyprus and within one of the largest TSC migrant communities in London, UK. Semi-structured interviews with members of the TSC community in London were conducted by using a questionnaire consisting both of open and closed questions. Open questions were aimed at identifying herbs, spices, medicinal plants and their uses. Also, graded questions were used to define informants' opinions as a quantitative parameter, constructing a statistical basis. A wide range of therapeutic claims were recorded, including 13 chronic illnesses within 85 different plant species, of which 18 were cited more than 10 times. The most frequently mentioned species were Mentha spicata, Salvia fruticosa and Pimpinella anisum. The plants recorded are frequently based on knowledge derived from Turkish-Cypriot traditions, but many examples of medicinal plants with a use based on UK or general western herbal medical traditions were also recorded. Informants highlighted the risk of knowledge loss in younger generations and thus this study serves as a repository of knowledge for use in the future. Due to a lack of knowledge about such usages in the healthcare professions, our study also highlights the need to develop information sources for use by healthcare practitioners in order to raise awareness about benefits and risks of such medical and health food products.

    The public reaction to a discovery, the character of the corresponding risk communication, as well as the possible impact on science and society all depend on the character of the phenomenon discovered, on the method of discovery, on the distance to the phenomenon and, last but not least, on the reliability of the announcement itself. The Rio Scale - proposed together with Jill Tarter just a decade ago at an IAA symposium in Rio de Janeiro - attempts to quantify the relative importance of such a “low probability, high consequence event”, namely the announcement of an ETI discovery. After the publication of the book “The Eerie Silence” by Paul Davies it is necessary to control how the recently suggested possible “technosignatures” or “technomarkers” mentioned in this book could be evaluated by the Rio Scale. The new London Scale, proposed at the Royal Society meeting in January 2010, in London, is a similar attempt to quantify the impact of an announcement regarding the discovery of ET life on an analogous ordinal scale between zero and ten. Here again the new concept of a “shadow biosphere” raised in this book deserves a special attention since a “weird form of life” found on Earth would not necessarily have an extraterrestrial origin, nevertheless it might be an important discovery in itself. Several arguments are presented that methods, aims and targets of “search for ET life” and “search for ET intelligence” are recently converging. The new problem is raised whether a unification of these two scales is necessary as a consequence of the convergence of the two subjects. Finally, it is suggested that experts in social sciences should take the structure of the respective scales into consideration when investigating case by case the possible effects on the society of such discoveries.

    With greater than 50 % of the global population residing in urban conurbations, poor urban air quality has a demonstrable effect on human health. OH and HO2 radicals, (collectively termed HOx) together with RO2 radicals, mediate virtually all of the oxidative chemistry in the atmosphere, being responsible for the transformation of primary emissions into secondary pollutants such as NO2, O3 and particulates. Understanding the chemistry of free-radicals in the atmosphere is essential in improving predictions of the lifetimes of pollutants and spatial scales of their transport within urban areas. Results from earlier field campaigns in urban and polluted regions have demonstrated the significance of HONO photolysis and alkene ozonolysis in the production of HOx radicals. In many cases, however, measurements of HONO have not been made, reducing the ability to evaluate model successes for OH in these environments. Here we present measurements of OH, HO2, RO2 and OH reactivity taken during the wintertime (January - February, 2012) and summertime (July - August, 2012) as part of the Clean air for London (ClearfLo) project in London. RO2 was detected using a newly developed flow-reactor laser-induced fluorescence technique which is able to discriminate between HO2 and organic peroxy radicals [1]. Low concentrations of radicals were observed during the wintertime, midday [OH], [HO2] and [RO2] were ~ 0.04, 0.8 and 1.5 pptv respectively, comparable to observations of radicals at other urban locations in winter [2,3,4], and which displayed a negative correlation with NO concentrations. OH reactivity was high and largely tracked the diurnal profiles of NOx and CO, with the highest reactivity ~100 s-1 observed during the morning rush hour. Analysis of factors controlling OH concentrations during the wintertime suggests that the formation of OH from the photolysis of O3 and subsequent reaction of O(1D) with H2O is a minor contribution both under high and low NOx conditions owing

    OBJECTIVES: To estimate population based incidence rates of gonorrhoea in an inner London area and examine relations with age, ethnic group, and socioeconomic deprivation. DESIGN: Cross sectional study. SETTING: 11 departments of genitourinary medicine in south and central London. SUBJECTS: 1978 first episodes of gonorrhoea diagnosed in 1994 and 1995 in residents of 73 electoral wards in the boroughs of Lambeth, Southwark, and Lewisham who attended any of the departments of genitourinary medicine. MAIN OUTCOME MEASURES: Yearly age, sex, and ethnic group specific rates of gonorrhoea per 100,000 population aged 15-59 years; rate ratios for the effects of age and ethnic group on gonorrhoea rates in women and men before and after adjustment for confounding factors. RESULTS: Overall incidence rates of gonorrhoea in residents of Lambeth, Southwark, and Lewisham were 138.3 cases yearly per 100,000 women and 291.9 cases yearly per 100,000 men aged 15-59 years. At all ages gonorrhoea rates were higher in non-white minority ethnic groups. Rate ratios for the effect of age adjusted for ethnic group and underprivilege were 15.2 (95% confidence interval 11.6 to 19.7) for women and 2.0 (1.7 to 2.5) for men aged 15-19 years compared with those over 30. After deprivation score and age were taken into account, women from black minority groups were 10.5 (8.6 to 12.8) times as likely and men 11.0 (9.7 to 12.6) times as likely as white people to experience gonorrhoea. CONCLUSIONS: Gonorrhoea rates in Lambeth, Southwark, and Lewisham in 1994-5 were six to seven times higher than for England and Wales one year earlier. The presentation of national trends thus hides the disproportionate contribution of ongoing endemic transmission in the study area. Teenage women and young adult men, particularly those from black minority ethnic groups, are the most heavily affected, even when socioeconomic underprivilege is taken into account.

    Miss Jean Jacomb born into a wealthy family, was at the age of 22 a student nurse at St Bartholomew's Hospital, London in 1917 where she nursed convalescent soldiers from World War I. Her midwifery training was in the slums around Whitechapel where a nurses uniform and medical bag provided a safe passage in the East End of London. For a while she worked in South Africa and India and returning to UK in 1923 she progressed to appointment as matron at the now re-named Royal Marsden Hospital in Chelsea. In 1938 she was appointed matron to The London Clinic during the years of World War II following which in 1949 she retired at the age of 55. She then travelled the world extensively by ship, always first class. She died in 1988. PMID:24944046

    2004-04-01

    Anatomical demonstration in the eighteenth century took place in many formats. In this essay I discuss public anatomical demonstration as performed by entrepreneurial anatomists in London between 1700 and 1740. These anatomists offered courses, advertised in newspapers, to anyone who was willing to pay. In contrast to courses offered in official settings to prospective physicians and surgeons, these courses emphasized natural philosophy and natural theology rather than practical knowledge. Entrepreneurial lecturers also aimed to entertain. In this article I examine the lectures of James Douglas, William Cheselden, and Frank Nicholls, each of whom differed significantly from the others in style and content but were all anatomical entrepreneurs. All of them, moreover, employed not only human cadavers but also living and dead animals in their lessons. I examine the content of the lectures and the motivations of the lecturers' audiences. I also argue that the prevailing historiographical representation of eighteenth-century science as "polite" requires considerable revision to accommodate as impolite an activity as public anatomy.

    Enrichment and elective culture for methylotrophs from sediment of the River Thames in central London yielded a diversity of pure cultures representing several genera of Gram-negative and Gram-positive bacteria, which were mainly of organisms not generally regarded as typically methylotrophic. Substrates leading to successful isolations included methanol, monomethylamine, dimethylamine, trimethylamine, methanesulfonate and dimethylsulfone. Several isolates were studied in detail and shown by their biochemical and morphological properties and 16S rRNA gene sequencing to be Sphingomonas melonis strain ET35, Mycobacterium fluoranthenivorans strain DSQ3, Rhodococcus erythropolis strain DSQ4, Brevibacterium casei strain MSQ5, Klebsiella oxytoca strains MMA/F and MMA/1, Pseudomonas mendocina strain TSQ4, and Flavobacterium sp. strains MSA/1 and MMA/2. The results show that facultative methylotrophy is present across a wide range of Bacteria, suggesting that turnover of diverse C(1)-compounds is of much greater microbiological and environmental significance than is generally thought. The origins of the genes encoding the enzymes of methylotrophy in diverse heterotrophs need further study, and could further our understanding of the phylogeny and antiquity of methylotrophic systems.

    Background Mass gatherings, such as the Olympic and Paralympic Games, represent an enormous logistical challenge for the host city. Health service planners must deliver routine and emergency services and, in recent Games, health legacy initiatives, for the local and visiting population. However there is little evidence to support their planning decisions. We therefore evaluated the strategic health planning programme for the London 2012 Olympic and Paralympic Games to identify generalisable information for future Games. Methods We thematically analysed data from stakeholder interviews and documents. The data were prospectively collected in three phases, before, during and after the Games. Findings We identified five key themes: (1) Systemic Improvement for example in communications, (2) Effective relationships led to efficiencies and permanent gains, such as new relationships with the private sector (3) Difficult relationships led to inefficiencies, for instance, duplication in testing and exercising emergency scenarios, (4) Tendency to over-estimate demand for care, particularly emergency medicine, and (5) Difficulties establishing a health legacy due to its deprioritisation and lack of vision by the programme team. Interpretation Enduring improvements which are sustained after the Games are possible, such as the establishment of new and productive partnerships. Relationships must be established early on to avoid duplication, delay and unnecessary expense. There should be greater critical evaluation of the likely demand for health services to reduce the wasting of resources. Finally, if a health legacy is planned, then clear definitions and commitment to its measurement is essential. PMID:24647613

  12. Stability of topological defects in chiral superconductors: London theory.

    SciTech Connect

    Vakaryuk, V.

    2011-12-22

    This paper examines the thermodynamic stability of chiral domain walls and vortices-topological defects which can exist in chiral superconductors. Using London theory it is demonstrated that at sufficiently small applied and chiral fields the existence of domain walls and vortices in the sample is not favored and the sample's configuration is a single domain. The particular chirality of the single-domain configuration is neither favored nor disfavored by the applied field. Increasing the field leads to an entry of a domain-wall loop or a vortex into the sample. The formation of a straight domain wall is never preferred in equilibrium. Values of the entry (critical) fields for both types of defects, as well as the equilibrium size of the domain-wall loop, are calculated. We also consider a mesoscopic chiral sample and calculate its zero-field magnetization, susceptibility, and a change in the magnetic moment due to a vortex or a domain-wall entry. We show that in the case of a soft domain wall whose energetics is dominated by the chiral current (and not by the surface tension) its behavior in mesoscopic samples is substantially different from that in the bulk case and can be used for a controllable transfer of edge excitations. The applicability of these results to Sr{sub 2}RuO{sub 4} - a tentative chiral superconductor - is discussed.

    This paper investigates the origin, fluxes, and transformation of carbon compounds within black crusts on the stone walls of the Tower of London. The crusts were analyzed for elemental and organic carbon, including the water soluble fraction. The stratigraphy of the old, thicker crusts highlighted the presence of prismatic particles, spherical aluminosilicates and metals, and carbonaceous particles. These are indicative of wood, coal and oil combustion processes. Elemental carbon and low solubility compounds such as oxalates appeared to be conserved because of long residence times. Conversely, more soluble ions, like chloride and formate would be removed from the layers relatively quickly by rainfall. At higher organic carbon concentrations acetic acid may be produced within the crusts from biological transformations. Currently, traffic sources contribute to increasingly organic rich crusts. The deposition of elemental carbon to buildings darkens surfaces and has important aesthetic implications. The increased organic content may have further aesthetic consequence by changing the color of buildings to warmer tones, particularly browns and yellows. Management of historic buildings requires us to recognize the shift away from simple gypsum crusts to those richer in organic materials. 26 refs., 6 figs., 1 tab.

    On 1 November the Geological Society of London (GSL) published a statement (http://www.geolsoc.org.uk/gsl/site//GSL//lang/en/climatechange) about the geological evidence relating to past climates, atmospheric carbon levels, and their interrelationships. The online version also carries a list of recommendations for further reading. The GSL's Geoscientist magazine (http://www.geolsoc.org.uk/gsl/site/GSL/lang/en/page8578.html) reported Bryan Lovell, GSL president, as saying, “Climate change is a defining issue of our time, whose full understanding needs geology's long perspective. Earth scientists can read…the geological record of changes in climate that occurred long before we were around to light so much as a camp fire, let alone burn coal, gas and oil. A dramatic global warming event 55 million years ago gives us a particularly clear indication of what happens when there is a sudden release of 1500 billion tonnes of carbon into Earth's atmosphere. It gets hot, the seas become more acid, and there is widespread extinction of life. We are a third of the way to repeating that ancient natural input of carbon through our own agency. The message from the rocks is that it would be a good idea to stop pulling that carbon trigger.”

    During the past five years the incidence of imported malaria increased among patients seen in East Birmingham Hospital and in St Thomas's Hospital, London. Plasmodium vivax was the predominant species in Birmingham, and was almost always acquired by Asian immigrants visiting the Indian subcontinent. In St Thomas's P falciparum was most commonly imported, usually by African immigrants visiting Nigeria and Ghana. Two patients (one Irish, one Japanese) died of falciparum malaria after visiting tropical Africa. In both hospitals the immigrant patients had seldom taken prophylactic drugs, and the few who had, ceased to do so on arrival in the UK and sometimes before leaving the malarious country. Apparently immigrants who visit their homeland do not consult their general practitioners before travelling, are given inappropriate advice, or do not take appropriate advice when given. Since the incidence of imported falciparum malaria in the UK is rising, the following points should be considered: the infection may be lethal, particularly in patients lacking immunity; it can mimic other diseases, which may lead to delayed diagnosis; severe disease may be associated with few parasites on a blood film, and even if the result is negative further tests should be performed; clinicians and hospital pharmacists should be aware of the need to keep permanent stocks of parenteral chloroquine and quinine preparations.

    There have been relatively few tracer experiments carried out that have looked at vertical plume spread in urban areas. In this paper we present results from two tracer (cyclic perfluorocarbon) experiments carried out in 2006 and 2007 in central London centred on the BT Tower as part of the REPARTEE (Regent's Park and Tower Environmental Experiment) campaign. The height of the tower gives a unique opportunity to study vertical dispersion profiles and transport times in central London. Vertical gradients are contrasted with the relevant Pasquill stability classes. Estimation of lateral advection and vertical mixing times are made and compared with previous measurements. Data are then compared with a simple operational dispersion model and contrasted with data taken in central London as part of the DAPPLE campaign. This correlates dosage with non-dimensionalised distance from source. Such analyses illustrate the feasibility of the use of these empirical correlations over these prescribed distances in central London.

Methods A retrospective analysis of case notes from patients admitted with enteric fever during 2007 to 2012 with a microbiologically confirmed diagnosis was undertaken. Details on clinical presentation, travel history, demographic data, laboratory parameters, treatment, patient outcome and vaccination status were collected. Results Clinical case notes were available for 98/129 (76%) patients including 69 Salmonella enterica serovar Typhi (S. Typhi) and 29 Salmonella enterica serovar Paratyphi (S. Paratyphi). Thirty-four patients (35%) were discharged from emergency medicine without a diagnosis of enteric fever and then readmitted after positive blood cultures. Seventy-one of the 98 patients (72%) were UK residents who had travelled abroad, 23 (23%) were foreign visitors/new entrants to the UK and four (4%) had not travelled abroad. Enteric fever was not considered in the initial differential diagnosis for 48/98 (49%) cases. The median length of hospital stay was 7 days (range 0–57 days). The total cost of bed days for managing enteric fever was £454,000 in the two hospitals (mean £75,666/year). Median time to clinical resolution was five days (range 1–20). Seven of 98 (7%) patients were readmitted with relapsed or continued infection. Six of the 71 (8%) patients had received typhoid vaccination, 34 (48%) patients had not received vaccination, and for 31 cases (44%) vaccination status was unknown. Conclusions Further interventions regarding education and vaccination of travellers and recognition of the condition by emergency medicine clinicians in travellers to South Asia is required.

    Backgrounds and aims Problem gambling occurs at higher levels in the homeless than the general population. Past work has not established the extent to which problem gambling is a cause or consequence of homelessness. This study sought to replicate recent observations of elevated rates of problem gambling in a British homeless sample, and extend that finding by characterizing (a) the temporal sequencing of the effect, (b) relationships with drug and alcohol misuse, and (c) awareness and access of treatment services for gambling by the homeless. Methods We recruited 72 participants from homeless centers in Westminster, London, and used the Problem Gambling Severity Index to assess gambling involvement, as well as DSM-IV criteria for substance and alcohol use disorders. A life-events scale was administered to establish the temporal ordering of problem gambling and homelessness. Results Problem gambling was evident in 23.6% of the sample. In participants who endorsed any gambling symptomatology, the majority were categorized as problem gamblers. Within those problem gamblers, 82.4% indicated that gambling preceded their homelessness. Participants displayed high rates of substance (31.9%) and alcohol dependence (23.6%); these were not correlated with PGSI scores. Awareness of treatment for gambling was significantly lower than for substance and alcohol use disorders, and actual access of gambling support was minimal. Discussion and conclusions Problem gambling is an under-recognized health issue in the homeless. Our observation that gambling typically precedes homelessness strengthens its role as a causal factor. Despite the elevated prevalence rates, awareness and utilization of gambling support opportunities were low compared with services for substance use disorders. PMID:27348556

    OBJECTIVE--To measure the prevalence of HIV and to describe established risk factors in female prostitutes. DESIGN--A cross sectional survey. SETTING--A genitourinary medicine clinic, streets, and magistrates' courts in London. SUBJECTS--280 female prostitutes recruited between April 1989 and August 1991. MAIN OUTCOME MEASURES--Infection with HIV-1, reported risk behaviours, and prevalence of sexually transmitted infections. RESULTS--228 of the women had HIV tests, and two (0.9% (95% confidence interval 0% to 2.1%)) were infected with HIV-1. Reported use of condoms was high for commercial clients and low for non-paying partners: 98% (251/255) of women used condoms with all clients and 12% (25/207) with non-paying partners for vaginal intercourse. Twenty two women were current or past injecting drug users. Of the 193 women examined for sexually transmitted infections, 27 had an acute infection (gonorrhoea, chlamydia, trichomonas, or primary genital herpes) at the time of interview. Infection was associated with younger age and increasing numbers of non-paying sexual partners, but not with duration of prostitution, numbers of clients, or reports of condom failures. When age and numbers of non-paying partners were analysed by logistic regression they remained significantly associated with sexually transmitted infections. CONCLUSIONS--A large and diverse sample of prostitutes had a low prevalence of infection with HIV and high levels of use of condoms in commercial sex. There was a significant risk of other sexually transmitted infections associated with prostitutes' non-commercial sexual relationships, in which unprotected sex is common. Interventions to reduce the risk of sexually transmitted infections in prostitutes should address both commercial and non-commercial sexual partnerships. PMID:8374417

    STUDY OBJECTIVE--To describe the association between self reported and externally assessed work characteristics and psychiatric disorder. DESIGN--Analysis of questionnaire data collected from the first phase of the Whitehall II study, a cohort study of an employed population. SETTING--Twenty civil service departments in London. PARTICIPANTS--Altogether 6900 male and 3414 female civil servants aged 35-55 years. MAIN RESULTS--High levels of subjective social support at work, control at work, job variety, and skill use were associated with greater satisfaction and wellbeing and less psychiatric disorder measured by the 30 item general health questionnaire (GHQ). High levels of subjective work pace and conflicting demands were associated with less satisfaction and wellbeing and greater psychiatric disorder. The combined effects of work characteristics were similar to the effects of the work characteristics considered separately, except that for men there was a small interaction between psychological demands and control on the GHQ. There was little overall support for the two factor job strain model. In contrast, objective indices of work were generally not associated with the psychological indices. Findings in men and women were generally comparable and were not significantly influenced by employment grade. CONCLUSIONS--Negative affectivity and a tendency to report negatively about both work and the psychological indices may partly explain the difference in the findings between subjective and objective work characteristics. However, subjective work characteristics were still associated with psychiatric disorder after adjusting for negative affectivity. The potential confounding effects of employment grade did not explain the association between either subjective or objective work characteristics and the psychological indices. While modifications to the work environment may directly reduce certain adverse physical health effects, the influence of work place design and

    Birch pollen is highly allergenic. Knowledge of daily variations, atmospheric transport and source areas of birch pollen is important for exposure studies and for warnings to the public, especially for large cities such as London. Our results show that broad-leaved forests with high birch tree densities are located to the south and west of London. Bi-hourly Betula pollen concentrations for all the days included in the study, and for all available days with high birch pollen counts (daily average birch pollen counts >80 grains/m3), show that, on average, there is a peak between 1400 hours and 1600 hours. Back-trajectory analysis showed that, on days with high birch pollen counts ( n = 60), 80% of air masses arriving at the time of peak diurnal birch pollen count approached North London from the south in a 180 degree arc from due east to due west. Detailed investigations of three Betula pollen episodes, with distinctly different diurnal patterns compared to the mean daily cycle, were used to illustrate how night-time maxima (2200-0400 hours) in Betula pollen counts could be the result of transport from distant sources or long transport times caused by slow moving air masses. We conclude that the Betula pollen recorded in North London could originate from sources found to the west and south of the city and not just trees within London itself. Possible sources outside the city include Continental Europe and the Betula trees within the broad-leaved forests of Southern England.

    The Russian psychologist Lev Vygotsky (1896-1934) left the Soviet Union only once to attend a conference on the education of the deaf in London. So far almost nothing was known about this trip, which took place in a period when Vygotsky was still completely unknown as a psychologist, both inside his own country and abroad. Making use of a newly discovered notebook, it proved possible to partially reconstruct Vygotsky's journey and stay in London. Vygotsky's very personal remarks show him to have been a very sensitive and spirited man, who was prey to strong emotions during the conference and afterwards. Rather surprisingly, Vygotsky's own paper about the education of the deaf was never presented during the conference and the stay in London appears to have had a limited value for his own scientific development.

    "This paper discusses the estimation and projection of small area populations in London, [England] and considers trends in intercensal social and demographic indices which can be calculated using these estimates. Information available annually on vital statistics and electorates is combined with detailed data from the Census Small Area Statistics to derive demographic component based population estimates for London's electoral wards over five year periods. The availability of age disaggregated population estimates permits derivation of small area social indicators for intercensal years, for example, of unemployment and mortality. Trends in spatial inequality of such indicators during the 1980s are analysed and point to continuing wide differentials. A typology of population and social indicators gives an indication of the small area distribution of the recent population turnaround in inner London, and of its association with other social processes such as gentrification and ethnic concentration."

    John Hughlings Jackson was associated with the London Hospital as a Lecturer and Physician for nearly 40 years while also on the staff at The National Hospital, Queen Square. His experience at the two hospitals was complementary; sometimes, a patient would be exchanged between the two hospitals. At the London Hospital, he was especially revered by students, colleagues and even by the House Governor, for his knowledge and his contributions to neurology. His ideas helped to resolve the chaotic contemporary understanding of neurological phenomena into a coherent whole, determining the direction of future neurological research in the following century. His life and work was supported and strengthened by the help and friendship of his colleagues at the London Hospital, especially Sir Jonathan Hutchinson. PMID:25585567

    The performance of the transport network and the associated movement of people was one of the most critical elements to London's successful delivery of the 2012 Olympic Games. During the planning stages Transport for London asked the London Borough of Newham to mitigate the impact of the authority's 13 500 employees on transport infrastructure close to the Olympic Park. To achieve this, the authority needed to understand the geographic distribution of its workforce and the demand it placed on roads and local transport hubs. The authority's Geospatial Team led the research based on four cross-referenced data sources, and spatial analysis was used to determine priorities for special absence arrangements and a commissioned coach service. The research was used to support a targeted information campaign but also presented considerations on large-scale data collection, the use of Human Resources data, and the degree to which the movement of people can be measured and managed.

    There have been relatively few tracer experiments carried out that have looked at vertical plume spread in urban areas. In this paper we present results from cyclic perfluorocarbon tracer experiments carried out in 2006 and 2007 in central London centred on the BT Tower as part of the REPARTEE (Regent's Park and Tower Environmental Experiment) campaign. The height of the tower gives a unique opportunity to study dispersion over a large vertical gradient. These gradients are then compared with classical Gaussian profiles of the relevant stability classes over a range of distances as well as interpretation of data with reference to both anemometry and LIDAR measurements made. Data are then compared with an operational model and contrasted with data taken in central London as part of the DAPPLE campaign looking at dosage compared with non-dimensionalised distance from source. Such analysis illustrates the feasibility of the use of these empirical correlations over these prescribed distances in central London.

    Objective To evaluate the effectiveness and cost of the pan-London pharmacy initiative, a programme that allows administration of seasonal influenza vaccination to eligible patients at pharmacies. Design We analysed 2013–2015 data on vaccination uptake in pharmacies via the Sonar reporting system, and the total vaccination uptake via 2011–2015 ImmForm general practitioner (GP) reporting system data. We conducted an online survey of London pharmacists who participate in the programme to assess time use data, vaccine choice, investment costs and opinions about the programme. We conducted an online survey of London GPs to assess vaccine choice of vaccine and opinions about the pharmacy vaccine delivery programme. Setting All London boroughs. Participants London-based GPs, and pharmacies that currently offer seasonal flu vaccination. Interventions Not applicable. Main outcome measures Comparison of annual vaccine uptake in London across risk groups from years before pharmacy vaccination introduction to after pharmacy vaccination introduction. Completeness of vaccine uptake reporting data. Cost to the National Health Service (NHS) of flu vaccine delivery at pharmacies with that at GPs. Cost to pharmacists of flu delivery. Opinions of pharmacists and GPs regarding the flu vaccine pharmacy initiative. Results No significant change in the uptake of seasonal vaccination in any of the risk groups as a result of the pharmacy initiative. While on average a pharmacy-administered flu vaccine dose costs the NHS up to £2.35 less than a dose administered at a GP, a comparison of the 2 recording systems suggests there is substantial loss of data. Conclusions Flu vaccine delivery through pharmacies shows potential for improving convenience for vaccine recipients. However, there is no evidence that vaccination uptake increases and the use of 2 separate recording systems leads to time-consuming data entry and missing vaccine record data. PMID:26883237

    We currently have an incomplete understanding of how weather varies across London and how the city's microclimate will intensify levels of heat, cold and air pollution in the future. There is a need to target priority areas of the city and to promote design guidance on climate change mitigation strategies. As a result of improvements in the accuracy of local weather data in London, an opportunity is emerging for designers and planners of the built environment to measure the impact of their designs on local urban climate and to enhance the designer's role in creating more informed design choices at an urban micro-scale. However, modelling the different components of the urban environment separately and then collating and comparing the results invariably leads to discrepancies in the output of local urban climate modelling tools designed to work at different scales. Of particular interest is why marked differences appear between the data extracted from local urban climate models when we change the scale of modelling from city to building scale. An example of such differences is those that have been observed in relation to the London Unified Model and London Site Specific Air Temperature model. In order to avoid these discrepancies we need a method for understanding and assessing how the urban environment impacts on local urban climate as a whole. A step to achieving this is by developing inter-linkages between assessment tools. Accurate information on the net impact of the urban environment on the local urban climate will in turn facilitate more accurate predictions of future energy demand and realistic scenarios for comfort and health. This paper will present two key topographies of London's urban environment that influence local urban climate: land use and street canyons. It will look at the possibilities for developing an integrated approach to modelling London's local urban climate from the neighbourhood to the street scale.

    To date, direct validation of city-wide emissions inventories for air pollutants has been difficult or impossible. However, recent technological innovations now allow direct measurement of pollutant fluxes from cities, for comparison with emissions inventories, which are themselves commonly used for prediction of current and future air quality and to help guide abatement strategies. Fluxes of NOx were measured using the eddy-covariance technique from an aircraft flying at low altitude over London. The highest fluxes were observed over central London, with lower fluxes measured in suburban areas. A footprint model was used to estimate the spatial area from which the measured emissions occurred. This allowed comparison of the flux measurements to the UK's National Atmospheric Emissions Inventory (NAEI) for NOx, with scaling factors used to account for the actual time of day, day of week and month of year of the measurement. The comparison suggests significant underestimation of NOx emissions in London by the NAEI, mainly due to its under-representation of real world road traffic emissions. A comparison was also carried out with an enhanced version of the inventory using real world driving emission factors and road measurement data taken from the London Atmospheric Emissions Inventory (LAEI). The measurement to inventory agreement was substantially improved using the enhanced version, showing the importance of fully accounting for road traffic, which is the dominant NOx emission source in London. In central London there was still an underestimation by the inventory of 30-40% compared with flux measurements, suggesting significant improvements are still required in the NOx emissions inventory.

    We propose and test a pair potential that is accurate at all relevant distances and simple enough for use in large-scale computer simulations. A combination of the Rydberg potential from spectroscopy and the London inverse-sixth-power energy, the proposed form fits spectroscopically determined potentials better than the Morse, Varnshi, and Hulburt-Hirschfelder potentials and much better than the Lennard-Jones and harmonic potentials. At long distances, it goes smoothly to the London force appropriate for gases and preserves van der Waals's "continuity of the gas and liquid states," which is routinely violated by coefficients assigned to the Lennard-Jones 6-12 form.

    Xiao, Yunlong; Zhang, Yong; Liu, Wenjian

    2014-10-01

    Both kinetically balanced (KB) and kinetically unbalanced (KU) rotational London orbitals (RLO) are proposed to resolve the slow basis set convergence in relativistic calculations of nuclear spin-rotation (NSR) coupling tensors of molecules containing heavy elements [Y. Xiao and W. Liu, J. Chem. Phys. 138, 134104 (2013)]. While they perform rather similarly, the KB-RLO Ansatz is clearly preferred as it ensures the correct nonrelativistic limit even with a finite basis. Moreover, it gives rise to the same "direct relativistic mapping" between nuclear magnetic resonance shielding and NSR coupling tensors as that without using the London orbitals [Y. Xiao, Y. Zhang, and W. Liu, J. Chem. Theory Comput. 10, 600 (2014)].

    2013-01-01

    This article argues that Sarah Waters' representation of London in her historical fictions Tipping the Velvet and The Night Watch is used to delineate the gendered bodies and sexual identities of her characters. A historical summary demonstrates that female masculinity was slowly mapped onto sexual identity between the 1880s and 1940s in Britain. The article argues that Waters' "inventive" use of this history allows her to question the construction of both historical and contemporary identifications. The way that Waters' characters are constricted and liberated by London's urban landscape demonstrates the spatial and temporal contingency of both gender and sexuality. PMID:23855943

    A growth rate in the average attendance of SANA branch meetings in East London was noted over the past five years, with the highest attendance figure during 1988. Despite this improvement an attendance figure of 17.05% is unacceptably low. The question of such poor attendance at the East London branch prompted the researchers to investigate the issue. Some of the interesting findings are that marital status and young children were not found to be reasons for not attending meetings. Members felt that SANA met their expectations in most respects, however, they felt that SANA did not do enough in respect of negotiations for improved salaries and conditions of service.

  8. Bangladeshi women's experiences of infant feeding in the London Borough of Tower Hamlets.

    PubMed

    Rayment, Juliet; McCourt, Christine; Vaughan, Lisa; Christie, Janice; Trenchard-Mabere, Esther

    2016-07-01

    This study examined the main factors that influence Bangladeshi women living in London's decisions to partially breastfeed their children, including the influence of older women within the community. Fifty-seven women of Bangladeshi origin living in the London Borough of Tower Hamlets took part in seven discussion groups between April and June 2013. Five groups were held with women of child-bearing age and two groups with older women in the community. A further eight younger women and three older women took part in one-on-one interviews. Interviews were also carried out with eight local health care workers, including public health specialists, peer support workers, breastfeeding coordinators and a health visitor. The influences on women's infant feeding choices can be understood through a 'socio-ecological model', including public health policy; diverse cultural influences from Bangladesh, London and the Bangladeshi community in London; and the impacts of migration and religious and family beliefs. The women's commitment to breastfeeding was mediated through the complexity of their everyday lives. The tension between what was 'best' and what was 'possible' leads them not only to partially breastfeed but also to sustain partial breastfeeding in a way not seen in other socio-cultural groups in the United Kingdom.

    Determining the contribution of wood smoke to air pollution in large cities such as London is becoming increasingly important due to the changing nature of domestic heating in urban areas. During winter, biomass burning emissions can exceed the contributions from traffic emissions, and have been identified as a major cause of exceedences of European air quality limits. The aim of this work was to quantify the contribution of biomass burning in London to concentrations of PM2.5 and determine whether local emissions or regional contributions were the main source of biomass smoke. To achieve this, a number of biomass burning chemical tracers were analysed at a site within central London and two sites in surrounding rural areas. Concentrations of levoglucosan, elemental carbon (EC), organic carbon (OC) and K+ were generally well correlated across the three sites. At all the sites, biomass burning was found to be a source of OC and EC, with the largest contribution of EC from traffic emissions, while for OC the dominant fraction likely included contributions from secondary organic aerosols, primary biogenic and cooking sources. Source apportionment of the EC and OC using average source ratios from published data was found to give reasonable estimation of the total carbon from non-fossil and fossil fuel sources based upon comparison with estimates derived from 14C analysis. Black carbon (BC) data from 2 and 7 wavelength Aethalometers were also apportioned into the contributions from biomass burning and traffic, based upon the enhanced absorption of wood smoke at UV wavelengths compared to BC. While the source apportionment of BC using this approach found similar trends to that observed for EC, higher percentage contributions of wood burning to BC were estimated. Based on a wood smoke mass conversion factor for levoglucosan, mean wood smoke mass at the sites was found to range from 0.78-1.0 μg m-3 during the campaign in January-February 2012. Measurements on a 160 m

Measurements on a 160 m tower in London suggested a similar ratio of brown to black carbon (reflecting wood burning and traffic respectively) in regional and London air. Peaks in the levoglucosan and K+ concentrations were observed to coincide with low ambient temperature, consistent with domestic heating as a major contributing local source in London. Overall, the source of biomass smoke in London was concluded to be a

  14. Assessing the sources and bioaccessibility of Lead in Soils from London

    NASA Astrophysics Data System (ADS)

    Cave, Mark R.; Wragg, Joanna; Chenery, Simon

    2013-04-01

    The lead content of soil is important since it is toxic to humans and particularly because children tend to more readily absorb lead than do adults: children absorb up to 40% into the bloodstream from ingested or inhaled lead, versus 5-15% in adults. Studies have shown that relatively low concentrations of lead in blood can lead to significant decrease in IQ of children (e.g. Jakubowski, 2011) leading to neuropathy and hypertension in adults. The British Geological Survey has recently completed a systematic high-density geochemical soil survey of the Greater London Area (GLA) in which over 6000 surface soil samples were collected and analysed for 50 elements. The Pb content of the soils range from 11 mg/kg to greater than 10000 mg/kg with mean and median values of 301 and 185 mg/kg, respectively. The ingestion bioaccessible fraction of Pb was measured using an in-vitro bioaccessibility test showing that 68% of the total Pb in London soils is bioaccessible. Measurement of Pb isotopic ratios in selected soils matched with those found in London air particulates and, to a lesser extent, with petrol lead. Self modelling mixture resolution of the 50 element geochemical data set was used to identify geochemically distinct components in the data with Pb being associated with 11 of the components which were of both natural and anthropogenic origin. Relationships between the soil components, the bioaccessible fraction and the Pb isotope ratios provided an indication of the sources of mobile lead in the London soils.

    2013-01-01

    We investigate the growth dynamics of Greater London defined by the administrative boundary of the Greater London Authority, based on the evolution of its street network during the last two centuries. This is done by employing a unique dataset, consisting of the planar graph representation of nine time slices of Greater London's road network spanning 224 years, from 1786 to 2010. Within this time-frame, we address the concept of the metropolitan area or city in physical terms, in that urban evolution reveals observable transitions in the distribution of relevant geometrical properties. Given that London has a hard boundary enforced by its long standing green belt, we show that its street network dynamics can be described as a fractal space-filling phenomena up to a capacitated limit, whence its growth can be predicted with a striking level of accuracy. This observation is confirmed by the analytical calculation of key topological properties of the planar graph, such as the topological growth of the network and its average connectivity. This study thus represents an example of a strong violation of Gibrat's law. In particular, we are able to show analytically how London evolves from a more loop-like structure, typical of planned cities, toward a more tree-like structure, typical of self-organized cities. These observations are relevant to the discourse on sustainable urban planning with respect to the control of urban sprawl in many large cities which have developed under the conditions of spatial constraints imposed by green belts and hard urban boundaries.

However, in the Spanish psychometric context, there is not an updated scale including recent contributions to entrepreneurship attitudes literature. The aim of this study is to present and validate a new scale named Escala de Actitudes Emprendedoras para Estudiantes-EAEE, (Entrepreneurial Attitudes Scale for Students, EASS), in two samples of high school and university Spanish students. Data comes from a cross-sectional survey of 524 high school and undergraduate students, from Valencia (Spain). Two confirmatory factor analyses (CFAs) were estimated, together with reliability and validity evidence of the scale. Results offered evidence of the adequate psychometric properties of the EASS. The CFAs showed overall and analytical adequate fit indexes (χ 2 (120) = 163.19 (p < .01), GFI = .906, CFI = .959, SRMR = .044, RMSEA = .040 [CI .022-.054]); reliability indices of the entrepreneurial attitudes were appropriate for most of the entrepreneurial attitudes (α were between .63 and .87 for the different dimensions); and external evidence relating entrepreneurial dimensions to personality traits was similar to in previous studies. The scale could be a useful instrument both for previous diagnosis and effectiveness assessment of programs on entrepreneurship promotion. PMID:26055696

    Objective To model the impacts of the bicycle sharing system in London on the health of its users. Design Health impact modelling and evaluation, using a stochastic simulation model. Setting Central and inner London, England. Data sources Total population operational registration and usage data for the London cycle hire scheme (collected April 2011-March 2012), surveys of cycle hire users (collected 2011), and London data on travel, physical activity, road traffic collisions, and particulate air pollution (PM2.5, (collected 2005-12). Participants 578 607 users of the London cycle hire scheme, aged 14 years and over, with an estimated 78% of travel time accounted for by users younger than 45 years. Main outcome measures Change in lifelong disability adjusted life years (DALYs) based on one year impacts on incidence of disease and injury, modelled through medium term changes in physical activity, road traffic injuries, and exposure to air pollution. Results Over the year examined the users made 7.4 million cycle hire trips (estimated 71% of cycling time by men). These trips would mostly otherwise have been made on foot (31%) or by public transport (47%). To date there has been a trend towards fewer fatalities and injuries than expected on cycle hire bicycles. Using these observed injury rates, the population benefits from the cycle hire scheme substantially outweighed harms (net change −72 DALYs (95% credible interval −110 to −43) among men using cycle hire per accounting year; −15 (−42 to −6) among women; note that negative DALYs represent a health benefit). When we modelled cycle hire injury rates as being equal to background rates for all cycling in central London, these benefits were smaller and there was no evidence of a benefit among women (change −49 DALYs (−88 to −17) among men; −1 DALY (−27 to 12) among women). This sex difference largely reflected higher road collision fatality rates for female cyclists. At older ages the modelled

    Planning for the London 2012 Olympic and Paralympic Games at the Public Health Laboratory London was based on the requirement to meet potential increased demand with scalable capacity. The aim of this study was to determine the impact on demand for microbiology gastrointestinal diagnostic services during the Games period. Retrospective cross-sectional time-series data analysis was used to assess the number of gastrointestinal specimens received in the laboratory and the number of positive results. There was no increase in the number of gastrointestinal specimens received during the Games period, thus the Games had no impact on demand for microbiology gastrointestinal diagnostic services at the laboratory. There was a decrease in the number of public health specimens received for culture [incidence rate ratio = 0.34, 95% confidence interval (CI) = 0.13-0.86, P = 0.02] and a decrease in the number of culture positive community specimens (odds ratio = 0.59, 95 % CI = 0.40-0.85, P = 0.005), suggesting a decrease in gastrointestinal illness during the Games period. As previous planning assumptions were not based on actual specimen activity, the results of this study may modify the extent of additional planning for microbiological services required for mass gatherings.

    Both kinetically balanced (KB) and kinetically unbalanced (KU) rotational London orbitals (RLO) are proposed to resolve the slow basis set convergence in relativistic calculations of nuclear spin-rotation (NSR) coupling tensors of molecules containing heavy elements [Y. Xiao and W. Liu, J. Chem. Phys. 138, 134104 (2013)]. While they perform rather similarly, the KB-RLO Ansatz is clearly preferred as it ensures the correct nonrelativistic limit even with a finite basis. Moreover, it gives rise to the same "direct relativistic mapping" between nuclear magnetic resonance shielding and NSR coupling tensors as that without using the London orbitals [Y. Xiao, Y. Zhang, and W. Liu, J. Chem. Theory Comput. 10, 600 (2014)]. PMID:25362275

    Abstract The type status is described of 39 taxa classified within the family Amphibulimidae (superfamily Orthalicoidea) and kept in the London museum. One taxon, Bulimus elaeodes Pfeiffer, 1853, is removed to the Strophocheilidae. Lectotypes are designated for Bulimus adoptus Reeve, 1849; Bulimus (Eurytus) eros Angas, 1878; Helix onca d'Orbigny, 1835; Amphibulima pardalina Guppy, 1868. The type status of the following taxon is changed to lectotype in accordance with Art. 74.6 ICZN: Strophocheilus (Dryptus) jubeus Fulton, 1908. As general introduction to this and following papers on Orthalicoid types in the Natural History Museum, a brief history of the London collection is given and several examples of handwriting from different authors are presented.

    The order of the superconducting phase transition is a classical problem. Single-component type-2 superconductors exhibit a continuous "inverted-X Y " phase transition, as was first demonstrated for U (1 ) lattice London superconductors by a celebrated duality mapping with subsequent backing by numerical simulations. Here we study this problem in multiband U (1 ) London superconductors and find evidence that by contrast the model has a tricritical point. The superconducting phase transition becomes first order when the Josephson length is sufficiently large compared to the magnetic field penetration length. We present evidence that the fluctuation-induced dipolar interaction between vortex loops makes the phase transition discontinuous. We discuss that this mechanism is also relevant for the phase transitions in multicomponent gauge theories with higher broken symmetry.

    We present a general theory of the singularity in the London penetration depth at symmetry-breaking and topological quantum critical points within a superconducting phase. While the critical exponents and ratios of amplitudes on the two sides of the transition are universal, an overall sign depends upon the interplay between the critical theory and the underlying Fermi surface. We determine these features for critical points to spin density wave and nematic ordering, and for a topological transition between a superconductor with Z2 fractionalization and a conventional superconductor. We note implications for recent measurements of the London penetration depth in BaFe2(As1-xPx)2 [K. Hashimoto , Science 336, 1554 (2012)SCIEAS0036-807510.1126/science.1219821].

    Syndromic surveillance is vital for monitoring public health during mass gatherings. The London 2012 Olympic and Paralympic Games represents a major challenge to health protection services and community surveillance. In response to this challenge the Health Protection Agency has developed a new syndromic surveillance system that monitors daily general practitioner out-of-hours and unscheduled care attendances. This new national system will fill a gap identified in the existing general practice-based syndromic surveillance systems by providing surveillance capability of general practice activity during evenings/nights, over weekends and public holidays. The system will complement and supplement the existing tele-health phone line, general practitioner and emergency department syndromic surveillance systems. This new national system will contribute to improving public health reassurance, especially to meet the challenges of the London 2012 Olympic and Paralympic Games. PMID:22892324

    A random sample of 270 general practitioners in London was interviewed to assess current practice and opinions about managing psychological and social problems related to HIV infection. Physicians caring for patients with HIV infection were asked about numbers of patients in their pratice with HIV or AIDS; consultation with third parties such as sexual partners or family; reports to employers and other third parties; terminal care; contact with HIV clinics; testing for HIV infection without consent; and the impact of patients with HIV infection on their practice. All physicians were asked about patients concerned with HIV infection; awareness of other health resources for patients with HIV infection; terminal care; "safer sex" education; confidentiality; interest in AIDS; intravenous drug users as patients; managing homosexual patients; and ethical considerations. King discusses the findings and draws conclusions about primary care of HIV-infected patients in London. PMID:2508884

    The decision was made in Britain three centuries ago that an educated populace was best able to deal with a public health crisis of staggering proportions--outbreaks of bubonic and pneumonic plague. As early as 1603, the printing press was enlisted to educate the public about urgent health issues. This education took several forms. The City of London, with the tacit permission of the Crown, printed bills of mortality that reported who was dying of what in London, detailed by parish, for the years in the seventeenth century when plague deaths were reported. New books about plague prevention and cures were published; older works were reprinted. The resulting wealth of data gave impetus to the evolution of the new field of epidemiological demographics, founded by John Graunt and Sir William Petty. Publishing in the plague years also established a model for informing the general populace that is not without parallel in today's "information society." Images PMID:9431429

    Angiostrongylus vasorum is a parasitic nematode that can cause serious and potentially fatal disease in dogs and other canids. The aim of this study was to determine the intermediate slug species infected in nature by sampling sites in Greater London and Hertfordshire located within a known hyperendemic region. Overall, A. vasorum larvae were recovered from 6/381 slugs (1.6%) by tissue digestion, and their identity was confirmed by PCR. Infected slugs originated from three different sites in the Greater London area: one in Waltham Forest and two in Bromley. Slugs parasitised by A. vasorum were identified by a combination of external morphological characteristics and molecular techniques and belonged to three different families: the Arionidae, the Milacidae and the Limacidae. This includes two new host records for the parasite: Arion distinctus and Tandonia sowerbyi. This is the first record of A. vasorum in the family Milacidae, indicating that the parasite has a broader intermediate host range than previously recognised. PMID:25195057

    Heterotopic ossification (HO) is the formation of bone at extraskeletal sites. Over 60% of amputees injured by improvised explosive devices in the recent conflict in Afghanistan have developed HO, resulting in functional impairment. It is hypothesised that a key aetiological factor is the blast wave; however, other environmental and medical risk factors, which the casualties have been exposed to, have also been postulated. The suicide terrorist bombings in London in 2005 resulted in many blast-related casualties, many of whom were managed by the Royal London Hospital. This cohort of severely injured patients whose injuries also included trauma-related amputations shared some, but not all, of the risk factors identified in the military population. We reviewed these patients, in particular to assess the presence or absence of military-established risk factors for the formation of HO in these casualties. PMID:25645697

    Outcome bias and hindsight bias are related, but how exactly? To remedy theoretical ambiguity and non-existent directly relevant empirical research, we contrast an older idea (Baron & Hershey, 1988, J. Pers. Soc. Psychol., 54, 569) that sees outcome bias as partly mediated through hindsight bias with the idea that the two biases independently affect decision evaluations. In an Internet study of retrospections on the 2012 London Olympics, evaluations of the Games' success and its foreseeability had independent effects on evaluations of the International Olympic Committee's decision to award the Olympics to London; there was no evidence of mediation. Further theoretical discussion emphasizes the need to distinguish between a holistic assessment of decisions and a more specific assessment of the decision-making process in future outcome bias research.

    Objective The study aimed to (1) establish the incidence of exercise-related sudden cardiac arrest (SCA) in London, (2) investigate survival from exercise-related SCA and (3) examine factors related to survival. Method This retrospective observational study examined 2 years’ data from the London Ambulance Service (LAS) cardiac arrest registry for patients in whom resuscitation was attempted following an out-of-hospital cardiac arrest (OHCA), a cardiac cause was presumed and the arrest occurred during or within 1 h of exercise. Results The incidence of exercise-related SCA in London was estimated to be 0.6 per 100 000 person-years which equated to 0.5% of all OHCA, and 1.5% of all OHCA with presumed cardiac aetiology and resuscitation attempted. The majority of cases were male and the incidence increased from age 40 years. Just under one-third of patients survived to hospital discharge. Survival in the Utstein comparator group (cases with presumed cardiac aetiology, resuscitation attempted, bystander witnessed and a presenting cardiac rhythm of ventricular fibrillation or tachycardia) was higher at 42%. Survival was significantly associated with initial cardiac rhythm (χ2=17.5, df=2, p<0.001) and bystander defibrillation (Fisher's exact test, p<0.05). Conclusions Incidence of exercise-related SCA in the general population in London is rare. Survival following exercise-related SCA was considerably higher than survival for all OHCA with presumed cardiac aetiology and resuscitation attempted attended by the LAS during the same period. The major limitation of the study is the likely under identification of cases of exercise-related SCA. PMID:26468401

    London' s Professional Support Unit (PSU) was launched in April 2012 at a time when changes and financial pressures across the health service were placing considerable demand on the medical and dental workforce. At the same time the infrastructure to support medical revalidation was established. The PSU provides developmental support to clinicians across London in all career grades and specialities, to sustain and restore them to contribute effectively to health service delivery across the capital. The costs of medical training are high. Maintaining doctors at work has to be cost effective. Clinicians in multicultural London require diverse resources, as increasing numbers have trained abroad. The PSU offers a holistic, tailor-made approach to professional and personal development with a range of resources and approaches. It provides proven high quality educational interventions, creating a linked and integrated service, providing clinicians with new opportunities. Access is by self-referral with resources targeted at those going through transitions in their professional lives, as well as those who have specific developmental needs. A collaborative approach across the PSU and its education and governance communities ensured the provision of personal support to over 1300 clinicians in its first year, together with interdisciplinary group learning opportunities. Online materials were created to assist individuals, workplace groups and a broad network of support and expertise. To maximise the effectiveness of the service, learning events were also held for those working within the PSU. In commending the PSU and its positive impact, the General Medical Council has recommended the model be shared nationally. At the same time the London's three Local Education Training Boards have recommended that the PSU expand to encompass a more diverse range of professional groups. Our challenge is how to extend such flexible, responsive and values-based support across the workforce

    Aim: To explore tuberculosis (TB) service users’ experiences and satisfaction with care provision. Background: Thirty-nine percent of all new UK TB cases occur in London. Prevalence varies considerably between and within boroughs. Overall, research suggests inadequate control of London’s TB transmission; TB has become a health care priority for all London Primary Care Trusts. Service users’ experiences and satisfaction with care provision have not been explored adequately previously. Methods: A qualitative research design, using semi-structured face-to-face interviews was used. Ten service users, purposively selected in key risk groups across London, were interviewed. All interviews were digitally recorded with users’ permission, transcribed verbatim, and analyzed thematically. Results: Participants were treated in local hospitals for 6–12 months. Treatment was administered by TB nurses to inpatients and outpatients receiving directly observed therapy in consultation with medical staff and home visits for complex cases. Two participants did not realize the importance of compliance. Overall, they were satisfied with many TB services’ aspects, communication, and service organization. Early access, low suspicion index amongst some GPs, and restricted referral routes were identified as service barriers. Other improvement areas were information provision on drug side effects, diet, nutritional status, and a few health professionals’ attitudes. The effects on people varied enormously from minimal impact to psychological shock; TB also affected social and personal aspects of their life. With regard to further support facilities, some positive views on managed accommodation by TB-aware professionals for those with accommodation problems were identified. Conclusion: This first in-depth study of TB service users’ experiences across London offers valuable insights into service users’ experiences, providing information and recommendations for a strategic

Background  During the early containment phase in England from April to June 2009, the national strategy for H1N1 pandemic influenza involved case investigation and treatment, and tracing and prophylaxis of contacts. Objective  To describe the relationship between early transmission of H1N1 pandemic influenza in London and age and socio‐economic status. Methods  Epidemiological data on cases of pandemic flu in London reported to the London Flu Response Centre were analysed to determine patterns of transmission. Results  There were 3487 reported cases (2202 confirmed, 1272 presumed and 14 probable) from 20 April to 28 June 2009, during the ‘containment’ period. The highest report rate of 206 per 100 000 (95% CI 195–218) was seen in primary school–age children (5−11 years) followed by 129 (95% CI 119–139) in secondary school–age children (12–18 years). Reports of cases were initially concentrated in affluent areas but overall showed a clear trend with deprivation and risk ratio of 2·32 (95% CI 1·94–2·78) between the most deprived and the least deprived. Conclusion  Early transmissions were highest amongst school‐aged children but linked with socio‐economic deprivation across all age groups. PMID:22236079

    Background HIV has changed from a rapidly deteriorating illness to a complex chronic disease, with increasing incidences of comorbidity, including cancer, and liver, lung and cardiovascular diseases. North West London has 6719 individuals living with the human immunodeficiency virus (HIV), 873 of whom reside in the London Borough of Brent. Traditionally, commissioning services have focused on HIV therapy alone without considering how comorbidity affects treatment outcome and total service costs. Setting The setting for the study was NHS Brent Primary Care Trust, London UK. Question What associated comorbidities are present in people in Brent (London, UK) living with HIV, and how common are they? Methods A point-prevalence audit of retrospective data was conducted on all HIV-positive patients in Brent (financial year 2011/12). Data were collected from genito-urinary medicine (GUM) services, community services and general practitioners (GPs) on HIV diagnosis, patient demographics and past/current comorbidities: hepatitis B and C, cardiovascular disease, diabetes and mental health disorders. Results This study identified that 29% of people living with HIV/AIDS (PLWHA) in Brent have at least one comorbidity. The most common was hepatitis, followed by mental health disorders and cardiovascular disease (CVD). Comorbidity was more likely in older male patients (in particular CVD and diabetes) and White patients (except for diabetes which was more common in Asian groups). Discussion/Conclusion Many PLWHA in Brent suffer from a number of other conditions, which appear largely independent of HIV. Findings confirm the need to treat HIV as a long-term condition, including patient education, empowerment and encouraging self-management. The multi-morbidity of many PLWHA suggests a role for both primary care and collaborative, holistic, patient-centred and individualised healthcare. Service providers and commissioners need to consider comorbidities in their treatment of and

    Introduction The objectives of this study were to examine relationships between neighbourhood-level and individual-level characteristics and physical activity in deprived London neighbourhoods. Methods In 40 of the most deprived neighbourhoods in London (ranked in top 11% in London by Index of Multiple Deprivation) a cross-sectional survey (n = 4107 adults aged > = 16 years), neighbourhood audit tool, GIS measures and routine data measured neighbourhood and individual-level characteristics. The binary outcome was meeting the minimum recommended (CMO, UK) 5×30 mins moderate physical activity per week. Multilevel modelling was used to examine associations between physical activity and individual and neighbourhood-level characteristics. Results Respondents living more than 300 m away from accessible greenspace had lower odds of achieving recommended physical activity levels than those who lived within 300 m; from 301–600 m (OR = 0.7; 95% CI 0.5–0.9) and from 601–900 m (OR = 0.6; 95% CI 0.4–0.8). There was substantial residual between-neighbourhood variance in physical activity (median odds ratio = 1.7). Other objectively measured neighbourhood-level characteristics were not associated with physical activity levels. Conclusions Distance to nearest greenspace is associated with meeting recommended physical activity levels in deprived London neighbourhoods. Despite residual variance in physical activity levels between neighbourhoods, we found little evidence for the influence of other measured neighbourhood-level characteristics. PMID:23922717

    Objectives To characterize paediatric presentations of stabbing to emergency departments across London and to audit existing referral rates to the police and social services against the new standard set by the General Medical Council. Design Retrospective multi-centre service evaluation/audit. Setting All emergency departments within London. Participants Patients under 18 years of age presenting to emergency departments with non-accidental stabbing between 1 April 2007 and 30 April 2009. Main outcome measures Patient age, nature of assault, assailant, injuries and management. Rates of documented referral to police and social services, as mandated by GMC guidance. Results A total of 381 presentations were identified from 20 out of the 32 hospitals in London, 160 of whom were less than 16 years old. The majority were seen only by emergency department staff and only a minority (28%) were admitted. Three died in the departments. A knife was the commonest weapon and the limbs the most common site of injury. Referrals to police were documented in only 30% of patients (43% if <16 years old) and to social services in 16% (31% if <16 years old) of those discharged. In the majority, there was no documentation (police 64%, social services 79%). Conclusions A significant number of paediatric stabbings present to emergency departments across London. The majority of these are discharged directly from departments. Of those discharged, documentation regarding referral rates to Police and Social Services was poor, and documented referral rates low. This study covered a period prior to the introduction of new General Medical Council guidance and a repeat audit to assess subsequent documented referrals is required. PMID:23885300

    The interactions and dynamics of molecules at surfaces and within pores are essential to many chemical processes, ranging from molecular storage to catalysis and self-assembly. A molecular level understanding of molecule-surface interactions is crucial for tuning surface/pore selectivity and reactivity. While it is clear that strong chemisorption bonds facilitate these interactions, the role of weaker van der Waals (vdW) forces, which include London dispersion and π-π stacking interactions, are often unknown or overlooked. Recent advances in density functional theory (DFT) have now made it possible to reliably account for London dispersion interactions. In this paper, I will discuss the use of one such technique, the Rutgers-Chalmers vdW non-local correlation functional,ootnotetextM. Dion, H. Rydberg, E. Schr"oder, B. I. Lundqvist and D. C.

Methods A point-prevalence audit of retrospective data was conducted on all HIV-positive patients in Brent (financial year 2011/12). Data were collected from genito-urinary medicine (GUM) services, community services and general practitioners (GPs) on HIV diagnosis, patient demographics and past/current comorbidities: hepatitis B and C, cardiovascular disease, diabetes and mental health disorders. Results This study identified that 29% of people living with HIV/AIDS (PLWHA) in Brent have at least one comorbidity. The most common was hepatitis, followed by mental health disorders and cardiovascular disease (CVD). Comorbidity was more likely in older male patients (in particular CVD and diabetes) and White patients (except for diabetes which was more common in Asian groups). Discussion/Conclusion Many PLWHA in Brent suffer from a number of other conditions, which appear largely independent of HIV. Findings confirm the need to treat HIV as a long-term condition, including patient education, empowerment and encouraging self-management. The multi-morbidity of many PLWHA suggests a role for both primary care and collaborative, holistic, patient-centred and individualised healthcare. Service providers and commissioners need to consider comorbidities in their treatment of and

    The rapid growth and climate of the Greater London region have contributed towards large deficits in water supply. Inexpensive, energy-efficient and sustainable water resource schemes are increasingly sought as a means to boost supply. Here, we propose a small-scale recycling scheme whereby tertiary-treated wastewater is pumped to the Cretaceous chalk of the London Basin. By taking advantage of the natural filtration properties of the underlying chalk, contaminants can be effectively attenuated over relatively short length scales to result in pure water. The problem is approached from four different scales. First, we define two localities in London where such a pumping scheme might operate; regions which combine a thick unsaturated zone and high chalk transmissivity, both essential to ensure maximum contaminant removal and minimum environmental impact. Secondly, the effects of pumping fluid into the Chalk at the two localities are quantified using a finite-difference groundwater flow model. We show that rivers impose a regular groundwater flow regime, whereas pre-existing abstraction wells will lead to less predictable results. Thirdly, we consider the effect of fractures on channelling rapid fluid flow within the rock mass. By digitising a fracture map based upon outcrop measurements from chalk exposed on the Kent coast similar to that beneath London, we quantify transport patterns of wastewater after injection. Imbibition to the chalk matrix (and therefore filtration) will occur where fluid pressure gradients are highest, for instance around disconnected fracture tips. Finally we demonstrate the efficacy of chalk in contaminant removal by injecting an analogue 'effluent' through a chalk core. ICP-AES analysis on the recovered solution shows the contaminants (viz. a suite of heavy metals) are arrested or removed over relatively small time- and length-scales. Numerical and analytical solutions fit the data poorly, shedding some light on the importance of

    Measurements of the ambient atmosphere in London Underground train compartments were made before and after a ban on smoking. Levels of nicotine and carbon monoxide and estimates of airborne particulates are given. This paper describes the analytical techniques used in measuring constituents of tobacco smoke in the ambient air of public environments. Levels observed were all found to be far lower than recommended OSHA limits for safe exposure. PMID:3810674

    London dispersion force is ubiquitous in nature, and is increasingly recognized to be an important factor in a variety of surface processes. Here we demonstrate unambiguously the decisive role of London dispersion force in non-equilibrium growth of ordered nanostructures on metal substrates using aromatic source molecules. Our first-principles based multi-scale modeling shows that a drastic reduction in the growth temperature, from ~1000°C to ~300°C, can be achieved in graphene growth on Cu(111) when the typical carbon source of methane is replaced by benzene or p-Terphenyl. The London dispersion force enhances their adsorption energies by about (0.5–1.8) eV, thereby preventing their easy desorption, facilitating dehydrogenation, and promoting graphene growth at much lower temperatures. These quantitative predictions are validated in our experimental tests, showing convincing demonstration of monolayer graphene growth using the p-Terphenyl source. The general trends established are also more broadly applicable in molecular synthesis of surface-based nanostructures. PMID:23722566

    A model is given, in variational form, in which volumic “Bean currents”, ruled by Bean's law, and surface “London currents” coexist. This macroscopic model generalizes Bean's one, by appending to the critical density j_c a second parameter, with the dimension of a length, similar to London's depth λ. The one-dimensional version of the model is investigated, in order to link this parameter with the standard observable H-M characteristics On propose un modèle, sous forme variationnelle, associant des “courants de Bean” volumiques, décrits par la loi de Bean, et des “courants de London”, surfaciques. Ce modèle macroscopique généralise celui de Bean, caractérisé par le courant critique j_c, et fait intervenir un second paramètre, homogène à une longueur, analogue au λ de London. La version unidimensionnelle du modèle est étudiée en détail de manière à relier ce paramètre à l'observation des caractéristiques H-M usuelles.

  4. Treating London-Dispersion Effects with the Latest Minnesota Density Functionals: Problems and Possible Solutions.

    It is shown that the latest Minnesota density functionals (SOGGA11, M11-L, N12, MN12-L, SOGGA11-X, M11, N12-SX, and MN12-SX) do not properly describe London-dispersion interactions. Grimme's DFT-D3 correction can solve this problem partially; however, double-counting of medium-range electron correlation can occur. For the related M06-L functional, the alternative VV10 van der Waals kernel is tested, but it experiences similar double-counting. Most functionals give unphysical dissociation curves for the argon dimer, an indication for method-inherent problems, and further investigation is recommended. These results are further evidence that the London-dispersion problem in density functional theory approximations is unlikely to be solved by mere empirical optimization of functional parameters, unless the functionals contain components that ensure the correct asymptotic long-range behavior. London dispersion is ubiquitous, which is why the reported findings are not only important for theoreticians but also a reminder to the general chemist to carefully consider their choice of method before undertaking computational studies.

    Methane stable isotope analysis, coupled with mole fraction measurement, has been used to link isotopic signature to methane emissions from the leading methane sources in the London region, such as landfills and gas leaks. A mobile Picarro G2301 CRDS analyser was installed in a vehicle, together with an anemometer and a Hemisphere GPS receiver, to measure atmospheric methane mole fractions and their relative location. When methane plumes were located and intercepted, air samples were collected in Tedlar bags, for δ13C-CH4 isotopic analysis by CF-GC-IRMS (Continous Flow-Gas Chromatography-Isotopic Ratio Mass Spectroscopy). This method provides high precision isotopic values, determining δ13C-CH4 to ±0.05 per mil. The bulk signature of the methane plume into the atmosphere from the whole source area was obtained by Keeling plot analysis, and a δ13C-CH4 signature, with the relative uncertainty, allocated to each methane source investigated. The averaged δ13C-CH4 signature for landfill sites around the London region is - 58 ± 3 ‰, whereas the δ13C-CH4 signature for gas leaks is fairly constant at -36 ± 2 ‰, a value characteristic of North Sea supply. The Picarro G2301 analyser was installed also on the roof of King's College London, located in the centre of the city, and connected to an air inlet located 7 meters above roof height. An auto-sampler was connected to the same air inlet and launched remotely when a high nocturnal build up was expected, allowing up to twenty air bags to be collected for methane isotopic analysis over a 24 hour period. The main source contributing to overnight methane build up in central London is fugitive gas, in agreement with inventories. From the isotopic characterisation of urban methane sources and the source mix in London, the contribution to the urban methane budget and the local distribution of the methane sources given in inventories can be validated.

    Free radicals control the photo-oxidative chemistry of the atmosphere, being responsible for the transformation of primary emissions into secondary pollutants such as NO2, O3, multifunctional species and particulates. Here we present measurements of OH, HO2 and RO2 radicals and OH reactivity recorded at North Kensington, Central London, during two Intensive Operational Periods (IOPs) of the Clear Air for London (Clearflo) project in the summer and winter of 2012. OH and HO2 were measured using laser-induced fluorescence (LIF) spectroscopy at low pressure (the FAGE technique), and RO2 was measured using the recently developed ROXLIF technique, which utilises an external flow-reactor interfaced to FAGE, and which is able to discriminate between HO2 and organic peroxy radicals. Through control of reagent gases we are further able to provide a separate measurement of those RO2 species which are known to give an interference for HO2 measurements (namely alkene, aromatic and large-chain alkane derived RO2). OH reactivity was measured using laser-flash photolysis combined with FAGE. Low concentrations of radicals were observed during the winter IOP, with mixing ratios of [OH] ~ 0.04 pptv, [HO2] ~ 0.4 pptv, and [RO2] ~ 1.6 pptv at noon, all displaying a negative correlation with NO. The photolysis of O3 and subsequent reaction of O(1D) with H2O vapour was only a minor contribution to radical production in winter, with photolysis of HONO a major radical source. The summer IOP coincided with the London Olympic Games, with a number of pollution events, with ozone peaking at 100 ppbv (exceeding EU air quality directives) and elevated radical concentrations (peak [OH] ~ 0.14 pptv, [HO2] ~ 4 pptv, [RO2] ~ 6.4 pptv) being observed. The net rate of ozone production was calculated from radical observations and agreed well with measured ozone production, suggesting that advection/dilution by continental air-masses was not playing a significant role in determining ozone

    During July and August 2012 the Summer Olympic Games were held in London. During this period, unusually high levels of traffic and visitors to the city were expected, it is important to understand the effect this had on the air quality in London during this period. To this end three novel CityScan instruments were installed in London from the 20th July though to the end of September; affording the unique opportunity to monitor the spatial and vertical structure of nitrogen dioxide within the boundary layer in unprecedented detail. The deployment was included as part of the large NERC funded ClearfLo project (Clean Air for London) involving many other institutions and complementary measurement techniques. CityScan is a Hemispherical Scanning Imaging Differential Optical Absorption Spectrometer (HSI-DOAS) which is has been optimised to measure concentrations of nitrogen dioxide. CityScan has a 95° field of view (FOV) between the zenith and 5° below the horizon. Across this FOV there are 128 resolved elements which are measured concurrently, the spectrometer is rotated azimuthally 1° per second providing full hemispherical coverage every 6 minutes. CityScan measures concentrations of nitrogen dioxide over specific lines of sight and due to the extensive field of view of the instrument this produces measurements which are representative over city-wide scales. Nitrogen dioxide is an important air pollutant which is produced in all combustion processes and can reduce lung function; especially in sensitised individuals. These instruments aim to bridge the gap in spatial scales between point source measurements of air quality and satellite measurements of air quality offering additional information on emissions, transport and the chemistry of nitrogen dioxide. More information regarding the CityScan technique can be found at http://www.leos.le.ac.uk/aq/index.html. The first of the three CityScan instruments was located in North Kensington, the second in Soho and third

    Long-term monitoring of CH4 at Egham, SW London, shows reduction in the source input since the mid 1990s. There is a distinct seasonal cycle, in part reflecting background variation, tracked by comparison with the Mace Head Atlantic record. Local emissions, led by higher fossil fuel consumption in the winter months, also contribute to the cycle. Inter-annual variability is in part meteorological. The urban increment can be estimated by comparing specific wind sectors (e.g. incoming SSW Atlantic air compared to easterly urban air). Ratios of CH4 to CO2, calculated from the continuous records, allow relative emissions of CH4 and CO2 to be quantified, providing immediate tests of inventories. Ratios of excess over background of CH4 to CO2 for periods of 7 consecutive days of easterly air flow to the Egham site (from London) indicate a reduction in CH4 emissions of 11% relative to CO2 over the period 1999-2007. Isotopes discriminate sharply between methane sources. Diurnal (Keeling plot) δ13CCH4 campaigns identify source mixes. For London, both CO2 and CH4 annual emissions are cited to 0.1 ton (i.e. to 9 significant figures of CO2, and to 6 figures for methane). However, it can be difficult to reconcile isotopic measurements of local methane increments with declared emissions budgets (Lowry et al., 2001). Rapid, inexpensive, small-sample isotopic techniques (Fisher et al., 2006) allow simple tests of the veracity of emissions declarations. Local emissions can be detected, by geographic location, given known background patterns. Moreover, seasonal variation can be tracked. This makes it potentially possible cheaply to audit emissions in populated areas. Lowry, D., et al. (2001) J. Geophys. Res., 106, 7427-48 Fisher, R., et al. (2006) Rapid Comm.
