  1. 19th century London dust-yards: a case study in closed-loop resource efficiency.

    The material recovery methods used by dust-yards in early 19th century London, England and the conditions that led to their development, success and decline are reported. The overall system developed in response to the market value of constituents of municipal waste, and particularly the high coal ash content of household 'dust'. The emergence of lucrative markets for 'soil' and 'breeze' products encouraged dust-contractors to recover effectively 100% of the residual wastes remaining after readily saleable items and materials had been removed by the thriving informal sector. Contracting dust collection to the private sector allowed parishes to keep the streets relatively clean, without the need to develop institutional capacity, and for a period this also generated useful income. The dust-yard system is, therefore, an early example of organised, municipal-wide solid waste management, and also of public-private sector participation. The dust-yard system had been working successfully for more than 50 years before the Public Health Acts of 1848 and 1875, and was thus important in facilitating a relatively smooth transition to an institutionalised, municipally-run solid waste management system in England. The dust-yards can be seen as early precursors of modern materials recycling facilities (MRFs) and mechanical-biological treatment (MBT) plants; however, it must be emphasised that dust-yards operated without any of the environmental and occupational health considerations that are indispensable today. In addition, there are analogies between dust-yards and informal sector recycling systems currently operating in many developing countries.

  4. 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.

  5. The "Dreadful Visitation": public health and public awareness in seventeenth-century London.

    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

  6. Limited urban growth: London's street network dynamics since the 18th century.

    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.

  7. The decline of adult smallpox in eighteenth-century London1

    2011-01-01

    Smallpox was probably the single most lethal disease in eighteenth-century Britain, but was a minor cause of death by the mid-nineteenth century. Although vaccination was crucial to the decline of smallpox, especially in urban areas, from the beginning of the nineteenth century, it remains disputed the extent to which smallpox mortality declined before vaccination. Analysis of age-specific changes in smallpox burials within the large west London parish of St Martin-in-the-Fields revealed a precipitous reduction in adult smallpox risk from the 1770s, and this pattern was duplicated in the east London parish of St Dunstan's. Most adult smallpox victims were rural migrants, and such a drop in their susceptibility is consistent with a sudden increase in exposure to smallpox in rural areas. We investigated whether this was due to the spread of inoculation, or an increase in smallpox transmission, using changes in the age patterns of child smallpox burials. Smallpox mortality rose among infants, and smallpox burials became concentrated at the youngest ages, suggesting a sudden increase in infectiousness of the smallpox virus. Such a change intensified the process of smallpox endemicization in the English population, but also made cities substantially safer for young adult migrants. PMID:22171404

  9. "Persons That Live Remote from London": Apothecaries and the Medical Marketplace in Seventeenth-and Eighteenth-Century Wales

    PubMed Central

    Withey, Alun

    2011-01-01

    Summary This article uses evidence from Welsh apothecary shops as a means to access the mechanisms of the "medical marketplace" in seventeenth- and eighteenth-century Wales. As a country physically remote from large urban medical centers, and with few large towns, Wales has often been overlooked in terms of medical commerce. Nevertheless, evidence suggests that Welsh apothecaries participated in broad and sophisticated networks of trade with London suppliers. Moreover, their shops contained a wide range of medicines from herbal simples to exotic ingredients and chemical preparations, highlighting the availability of such goods far from large urban centers.

  10. Sensing design and workmanship: the haptic skills of shoppers in eighteenth-century London.

    PubMed

    Smith, Kate

    2012-01-01

    This article explores how eighteenth-century shoppers understood the material world around them. It argues that retail experiences exposed shoppers to different objects, which subsequently shaped their understanding of this world. This article builds on recent research that highlights the importance of shop environments and browsing in consumer choice. More particularly, it differentiates itself by examining the practice of handling goods in shops and arguing that sensory interaction with multiple goods was one of the key means by which shoppers comprehended concepts of design and workmanship. In doing so, it affirms the importance of sensory research to design history. The article focuses on consumer purchases of ceramic objects and examines a variety of sources to demonstrate the role of haptic skills in this act. It shows how different literary sources described browsing for goods in gendered and satirical terms and then contrasts these readings against visual evidence to illustrate how handling goods was also represented as a positive act. It reads browsing as a valued practice requiring competence, patience and haptic skills. Through an examination of diary sources, letters and objects this article asks what information shoppers gained from touching various objects. It concludes by demonstrating how repetitive handling in search of quality meant that shoppers acquired their own conception of what constituted workmanship and design.

    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. Composition of Façon de Venise glass from early 17th century London in comparison with luxury glass of the same age

    NASA Astrophysics Data System (ADS)

    Cagno, S.; De Raedt, I.; Jeffries, T.; Janssens, K.

    SEM-EDX and LA-ICP-MS analyses were performed on a set of early 17th century London glass fragments. The samples originate from two archaeological sites (Aldgate and Old Broad Street) where glass workshops were active in this period. The great majority of the samples are made of soda glass. Two distinct compositional groups are observed, each typical of one site of provenance. The samples originating from the Old Broad Street excavation feature a silica-soda-lime composition, with a moderate amount of potash. The samples from Aldgate are richer in potassium and feature higher amounts of trace elements such as Rb, Zr and Cu. The distinction between the two groups stems from different flux and silica sources used for glassmaking. A comparison with different European glass compositions of that time reveals no resemblance with genuine Venetian production, yet the composition of the Old Broad Street glass shows a close similarity to that of fragments produced `à la façon de Venise' in Antwerp at the end of the 16th century. This coincides with historical sources attesting the arrival of glassworkers from the Low Countries in England and suggests that a transfer of technology took place near the turn of the century.

  13. Vauxhall’s post-industrial pleasure gardens: "death wish" and hedonism in 21st-century London.

    PubMed

    Andersson, Johan

    2011-01-01

    In recent years Vauxhall in south London has been transformed and rebranded as an urban leisure zone for gay men. Disused railway arches and warehouses have been converted into nightclubs and a significant night-time economy has developed rivalling Soho's existing gay village. However, with its commodified forms of public sex and high levels of recreational drug use, Vauxhall's club scene looks rather different from the British gay villages of the 1990s. This article examines how the area's nightlife entrepreneurs have capitalised on the recent liberalisation of licensing laws while drawing on the historical associations with the Vauxhall Pleasure Gardens (1660-1859) in attempts to market the area as a site of embedded hedonism. Overall, the aesthetic and cultural themes of Vauxhall's club scene seem to contradict earlier assumptions about the desexualisation and sanitisation of contemporary gay culture.

    2012-07-13

    Kind-Harts dreame (Fig. 1) is one of the proto-novels which first appeared in the Elizabethan age of literary wonders. It recounts the dream of the hero - a tooth-drawer (Kind-Hart) - who encounters the shades of five recently deceased characters, each of whom had been a famous star of their day in the London scene. Although short, and with medicine and dentistry occupying only part of the tale, the story contains invaluable detailed information about dental care in late Tudor England as observed by a layman. It is also an amusing read.

    2016-10-01

    The Industrial Revolution, beginning primarily in the UK, generated an increasing need for highly skilled technical people. Throughout the 19th century, technical instruction increased dramatically and the formation of schools specializing in science and technology grew quickly. In England, there was much motivation in favour of a national prestige center for science and technology centered in London. Central among the motivating forces was Queen Victoria's husband, Prince Albert. Although there were already existing specialist science and technology institutions in major English cities, the growth of superior institutions in other countries within Europe, especially Germany and the Charlottenburg area of Berlin (e.g., the Berlin Technical High School), encouraged important English dignitaries to become more competitive with continental Europe. As a result of this strong continental motivation, several science and technology institutions were built in the south Kensington part of London during the latter half of the 19th century. Imperial College, founded at the start of the 20th century, was a culmination and consolidation of several of these 19th century English institutions. Optical science and technology was an early beneficiary of the founding of Imperial College. This paper will attempt to provide the reader with an understanding of how great was the influence of the optical section of Imperial College in the further development of the world's optical science and technology.

  6. Stuart London's standard of living: re-examining the Settlement of Tithes of 1638 for rents, income, and poverty.

    PubMed

    2010-01-01

    The Settlement of Tithes of 1638 can be tested for biases in its London rents. Even so, it proves to be a relatively good source for seventeenth-century London, and for calculating associated median and mean rents, as well as a Gini coefficient of inequality for the distribution of resources. Through other evidence in the Settlement, rent/income ratios for London can be approximated, and from them estimates made of London's median income. Median rents and income also allow estimates of the percentage of Londoners in poverty. Though the last is inevitably disputable, the estimate holds up well to testing by other evidence.

    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.

    Professor Peter Rothwell of Oxford University chaired the annual Scientific Conference of the International Aspirin Foundation in London on 28 August 2015. It took the form of four sessions. Aspirin has more than one action in its effects on disease. Its acetylation of cyclooxygenase 2 (COX-2) in platelets leads to the blockade of pro-inflammatory chemicals and generation of anti-inflammatory mediators and increase in nitrous oxide (NO) production, which helps to preserve arterial endothelium. But platelets are not its only target. There is now evidence that aspirin has a direct antitumour effect on intestinal mucosal cells that block their potential transformation into cancer cells. Randomised placebo-controlled trials (RCTs) in people with histories of colorectal neoplasia have shown that aspirin reduces the risk of recurrent adenomas and reduces long-term cancer incidence in patients with Lynch syndrome. Among women given aspirin for cardiovascular disease, there were fewer cancers than in those given placebo. Epidemiological evidence has suggested that aspirin treatment after cancer is diagnosed reduces the incidence of metastases and prolongs survival, and long-term studies of anticancer treatment with aspirin are under way to confirm this. Apart from cancer studies, aspirin use is now firmly established as treatment for antiphospholipid syndrome (Hughes syndrome) and is being used to prevent and treat the heightened risk of cardiovascular disease in diabetes mellitus and in patients with HIV.

  10. A combined Raman microscopy, XRF and SEM-EDX study of three valuable objects - A large painted leather screen and two illuminated title pages in 17th century books of ordinances of the Worshipful Company of Barbers, London

    Raman microscopy has been used to identify the pigments decorating three valuable items owned by the Worshipful Company of Barbers (established in 1308 in London), one being a large leather screen dating to before 1712, the other two being illuminated title pages of books of ordinances of the Company dating to 1605 and 1658. Pigments which could not be fully characterised by this technique (particularly the green paints) have also been subject to XRF or SEM-EDX analysis. The combined analytical approach has shown that the pigments identified on all three items are typical of those in use as artists' pigments in the 17th C and include azurite, indigo, vermilion, red lead, pink and yellow lakes, verdigris, lead white, calcite (and chalk), gypsum, carbon-based black, and gold and silver leaf. However in the case of the screen alone, restoration in the 1980s has been carried out with different pigments - haematite, phthalocyanine green, rutile, and a mixture of azurite, malachite and barium sulfate. This work constitutes the first in-depth study of painted leatherwork and demonstrates that the palette used for this purpose is similar to that used on other works of art of the same date. It has also allowed the original colour schemes of the decorations to be determined where pigment degradation has occurred. The combined analysis has also provided a more complete understanding of the materials used for, or on, objects to which access is limited.

  13. 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.

    Historical data on the temperature and precipitation data for London has been combined with output from the Hadley Model to estimate the climate of London for the period 1100-2100 CE. This has been converted to other parameters such as freeze-thaw frequency and snowfall relevant to the weathering of stone facades. The pollutant concentrations have been estimated for the same period, with the historical values taken from single box modelling and future values from changes likely given current policy within the metropolis. These values are used in the Lipfert model to show that the recession from karst weathering dominates across the period, while the contributions of sulphur deposition seem notable only across a shorter period 1700-2000 CE. Observations of the late seventeenth century suggest London architects witnessed a notable increase in the recession rate and attributed “fretting quality” to “smoaks of the sea-coal”. The recession rates measured in the late twentieth century lend some support to the estimates from the Lipfert model. The recession looks to increase only slightly, and frost shattering will decrease while salt weathering is likely to increase.

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

    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. A greater stink of a

    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.

  4. Millennium-long damage to building materials in London.

    PubMed

    Brimblecombe, Peter; Grossi, Carlota M

    2009-02-01

    Damage functions from a range of sources are used to estimate deterioration of carbonate stone, iron and copper, in addition to the rate of blackening of stone surfaces in London across the period 1100-2100 CE. Meteorological and pollution input is available for only a relatively short part of this span, so non-instrumental weather records and modelled pollution are utilised for historic values, while future climate is adapted from the HadCM3A2 model output and pollution assessed from likely regulatory trends. The results from the different damage functions compare reasonably well showing comparable changes in damage rates with time. A potential square-root dependence of change in deposition velocity of SO2 to limestone suggests a possible overestimate of damage when pollution is high. Deterioration is especially intense from the 1700s. It is difficult to be certain whether the corrosion of copper accelerated as early as this or it developed in the 20th century. Nevertheless all the functions predict a decline in copper corrosion from the end of the 20th century. A blackening function was developed to relate elemental carbon concentration and the colour of deposited particulate matter to blackening rate, which suggests that soiling was particularly rapid in the late 19th century. The increase and subsequent decrease in damage to building materials is interpreted in terms of a Kuznets curve. The centuries where pollution controlled damage to durable building material seems to be over. Weathering, in a changing climate may have the greatest impact in the future.

    2002-03-01

    Social reformer Charles Booth undertook a massive survey into the social and economic conditions of the people of London at the end of the 19th century. An important innovation of his Inquiry was the construction of large, detailed maps displaying social class of inner London on a street-by-street basis. These provide a detailed and vivid picture of the geography of poverty and affluence at this time. These maps have been digitised, georeferenced and linked to contemporary ward boundaries allowing Booth's measurement of social class to be matched to the measurement of social class in the 1991 census of population and standardised mortality ratios derived for all causes of death in the survey area between 1991 and 1995. The social class data were used to derive an index of relative poverty for both time periods and a comparison of the geographies of relative poverty and their relationship with contemporary mortality was made. Although the overall standard of living had increased, the geography of poverty at the end of the 19th century was very similar to that at the end of the 20th century. Moreover, the geography of all causes of death for people over the age of 65 was more strongly related to the geography of poverty in the late 19th century than contemporary patterns of poverty. This relationship was also true for mortality for specific diseases that are related to deprivation in early life. The paper concludes that the spatial patterns of poverty in inner London are extremely robust and a century of change has failed to disrupt it.

  10. Urban smoke concentrations at Kew, London, 1898-2004

    NASA Astrophysics Data System (ADS)

    Harrison, R. G.

    Historical smoke concentrations at monthly resolution for the early twentieth century are found for Kew Observatory, London, using the atmospheric electricity proxy technique. Smoke particles modify the electrical properties of urban air: an increase in smoke concentration reduces air's electrical conductivity and increases the Potential Gradient (PG). Calibrated PG data are available from Kew since 1898, and air conductivity was measured routinely between 1909 and 1979 using the technique developed by C.T.R. Wilson. Automated smoke observations at the same site overlap with the atmospheric electrical measurements from 1921, providing an absolute calibration to smoke concentration. This shows that the late nineteenth century winter smoke concentrations at Kew were approximately 100 times greater than contemporary winter smoke concentrations. Following smoke emission regulations reducing the smoke concentration, the electrical parameters of the urban air did not change dramatically. This is suggested to be due to a composition change, with an increase in the abundance of small aerosol compensating for the decrease in smoke.

    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

  15. Mortality and temperature in Sofia and London

    Pattenden, S; Nikiforov, B; Armstrong, B

    2003-01-01

    Study objective: Heat and cold have been associated with increased mortality, independently of seasonal trends, but details are little known. This study explores associations between mortality and temperature in two European capitals—Sofia and London—using four years of daily deaths, air pollution, and weather data. Design: Generalised additive models were used to permit non-linear modelling of confounders such as season and humidity, and to show the shape of mortality-temperature relations—using both two day and two week average temperatures separately. Models with linear terms for heat and cold were used to estimate lags of effect, linear effects, and attributable fractions. Participants: 44 701 all age all cause deaths in Sofia (1996–1999) and 256 464 in London (1993–1996). Main results: In London, for each degree of extreme cold (below the 10th centile of the two week mean temperature), mortality increased by 4.2% (95% CI 3.4 to 5.1), and in Sofia by 1.8% (0.6 to 3.9). For each degree rise above the 95th centile of the two day mean, mortality increased by 1.9% (1.4 to 2.4) in London, and 3.5% (2.2 to 4.8) in Sofia. Cold effects appeared after lags of around three days and lasted—particularly in London—at least two weeks. Main heat effects occurred more promptly. There were inverse associations at later lags for heat and cold in Sofia. Conclusions: Average temperatures over short periods do not adequately model cold, and may be inadequate for heat if they ignore harvesting effects. Cold temperatures in London, particularly, seem to harm the general population and the effects are not concentrated among persons close to death. PMID:12883072

    PubMed

    Chamberland, Celeste

    2009-07-01

    As the largest and most civically active body of medical practitioners in the late Tudor and early Stuart period, surgeons played a vital role in London's urban landscape, but remained precariously vulnerable to abasement due to the regular contact with death and disease necessitated by their work. Based on an analysis of guild records, printed surgical manuals, and conduct literature, this study explores the emergent corporate ethos of London's Barber-Surgeons' Company and addresses the identity formation of surgeons in the late-sixteenth and early-seventeenth centuries. By implementing codes of conduct and uniform standards of practice, punishing transgressions of propriety, and developing legislation to limit the activities of unlicensed and foreign practitioners, Company officers ardently sought social and occupational legitimacy within a milieu characterized by a tremendous emphasis on status and hierarchy. Rooted in methodology drawn from the social history of medicine and cultural anthropology, this study argues that in response to the persistent stigma associated with their work and London's increasingly prevalent culture of credit, surgeons, like other artisanal groups, sought to enhance their social legitimacy and occupational respectability by manipulating contemporary social rituals, reinforcing the honorable associations of their work, and preserving the veneer of brotherhood and camaraderie.

    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

    NASA Astrophysics Data System (ADS)

    L'E Turner, Gerard

    2001-01-01

    Europe in the sixteenth century experienced a period of unprecedented vitality and innovation in the spheres of science and commerce. The Americas had been discovered and the colonizing nations had an urgent need for mathematical instruments for navigation and surveying. In 1540 the Elizabethan age saw the establishment of the precision instrument-making trade in London, a trade that would become world-famous in the succeeding two centuries. The mathematical instruments needed by astronomers, navigators, and surveyors owe much of their development to the work of the Flemish mathematician and astronomer, Gemma Frisius, and to the map and globe maker, Gerard Mercator, both of whom studied at Louvain. However it was Thomas Gemini who is credited with starting the London trade in 1540: his reputation came from making the plates for his own printing of the Anatomy of Vesalius, and the astrolabs he made and presented to Edward VI and Elizabeth I, which survive today. He was followed by Humphrey Cole, and other makers whose instruments have survived, including Ryther, Knyvyn, and Whitwell. This book first describes the context in which the Elizabethan trade began, and the influence of the instruments taken to Florence by Sir Robert Dudley in 1606. The second part catalogues in detail every surviving instrument from this period, signed and unsigned, that has been traced. The catalogue is accompanied by fine photographs which illustrate both the instruments and the techniques used to identify unsigned instruments.

    Simpson, Marcus B; Simpson, Sallie W

    2008-01-01

    John Lawson's "A New Voyage to Carolina," an important source document for American colonial natural history, was first printed in 1709 in "A New Collection of Voyages and Travels," a two-volume set that also contained travel books translated by John Stevens. Lawson's publishers were leaders in the book trade of early eighteenth century London, and the "New Voyage" is typical of the resurgent popular interest in foreign travel narratives and exotic flora and fauna that began in the late 1600s. The "New Collection" was among the earliest examples of books published in serial instalments or fascicles, a marketing strategy adopted by London booksellers to broaden the audience and increase sales. Analysis of London issues of the "New Voyage" indicates that the 1709, 1711, 1714, and 1718 versions are simply bindings of the original, unsold sheets from the 1709 "New Collection" edition, differing only by new title-pages, front matter, and random stop-press corrections of type-set errors. Lawson's "New Voyage" illustrates important aspects of the British book trade during the hand press period of the early eighteenth century.

  1. The passing of the night watch: night nursing reform in the London teaching hospitals, 1856-90.

    PubMed

    Helmstadter, C

    1994-01-01

    At the beginning of the nineteenth century a separate team of women called the "night watch" was responsible for the night nursing in the London teaching hospitals. Rough, uneducated, and frequently the "scrubbers," or charwomen, who cleaned the halls and stairways in the hospitals in the daytime, the night watchers came to be closely identified with Dickens's Sarah Gamp. As the century progressed, the expanding capabilities of the new academic medicine forced an improvement in the standard of nursing. The difficulty in finding clinically experienced nurses who were willing to work nights at an affordable price, however, made it possible for the night watchers to remain in the new professionally organized hospital long after such unskilled and undisciplined workers had been phased out of other areas of the late Victorian workforce. By the end of the century when hospitals began rotating partially trained probationer, or student, nurses onto nights, the night watchers finally disappeared from the teaching hospitals.

    Previous studies have a demonstrated a linkage between terrorist attacks and the operation of financial markets. This article focuses on terrorist events carried out over the last five years and examines how they have been perceived among participants on the London financial market. Data from the London options market suggest a high degree of sensitivity to these events. We argue that this sensitivity reveals a vulnerability in the financial markets should the recent trends in terrorist activity continue.

  3. Modernization Of Saint Pancras And King's Cross Railway Stations In London

    2015-09-01

    The article concerns the renovation and modernization of two London railway stations - St. Pancras and King`s Cross. Both stations were built in the middle of the nineteenth century and are an example of industrial heritage. A characteristic feature that distinguishes the two buildings is the metal (iron) structure with a glass canopy. The St. Pancras railway station was characterized by a hall with the largest span in the world, and today is one of the leading examples of using iron in the development of architecture and building structures. Both stations have experienced periods of flourishing and stagnation throughout their history. There were even plans to demolish the old stations and build new facilities and in their place. Now, after the successful modernization of St. Pancras and King's Cross railway stations, they serve as good examples of the adaptation of transport utilities to modern needs, while respecting their historic structure. The problems that the designers and contractors were faced with during the renovation and modernization of the two London stations also deserve attention.

  5. century drying

    2014-11-01

    Global warming is expected to increase the frequency and intensity of droughts in the twenty-first century, but the relative contributions from changes in moisture supply (precipitation) versus evaporative demand (potential evapotranspiration; PET) have not been comprehensively assessed. Using output from a suite of general circulation model (GCM) simulations from phase 5 of the Coupled Model Intercomparison Project, projected twenty-first century drying and wetting trends are investigated using two offline indices of surface moisture balance: the Palmer Drought Severity Index (PDSI) and the Standardized Precipitation Evapotranspiration Index (SPEI). PDSI and SPEI projections using precipitation and Penman-Monteith based PET changes from the GCMs generally agree, showing robust cross-model drying in western North America, Central America, the Mediterranean, southern Africa, and the Amazon and robust wetting occurring in the Northern Hemisphere high latitudes and east Africa (PDSI only). The SPEI is more sensitive to PET changes than the PDSI, especially in arid regions such as the Sahara and Middle East. Regional drying and wetting patterns largely mirror the spatially heterogeneous response of precipitation in the models, although drying in the PDSI and SPEI calculations extends beyond the regions of reduced precipitation. This expansion of drying areas is attributed to globally widespread increases in PET, caused by increases in surface net radiation and the vapor pressure deficit. Increased PET not only intensifies drying in areas where precipitation is already reduced, it also drives areas into drought that would otherwise experience little drying or even wetting from precipitation trends alone. This PET amplification effect is largest in the Northern Hemisphere mid-latitudes, and is especially pronounced in western North America, Europe, and southeast China. Compared to PDSI projections using precipitation changes only, the projections incorporating both

  6. Multifractal to monofractal evolution of the London street network

    Murcio, Roberto; Masucci, A. Paolo; Arcaute, Elsa; Batty, Michael

    2015-12-01

    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.

  7. Cosmopolitanism, geographical imaginaries and belonging in North London.

    PubMed

    Devadason, Ranji

    2010-01-01

    Cosmopolitanism has been described as the cultural habitus of globalisation. It is therefore, albeit defined somewhat loosely, often associated with ethnically diverse, global cities. This paper considers the extent to which London engenders cosmopolitan values amongst its residents. It draws on survey data from the LOCAL MULTIDEM study of minorities' political participation to address these themes. The analysis examines perceptions of respect, belonging and geographical imaginaries - amongst established minorities and the ethnic majority - in north London. It is argued that cosmopolitan ethics are transformative and dialectical and, critically, cannot remain the preserve of the privileged in multi-ethnic neighbourhoods. The analysis presented demonstrates that a sense of belonging and cosmopolitan imaginaries are not evenly accessed by different ethnic groups; notably, that Bangladeshi Londoners who are born and bred in the city are less likely to appropriate these discourses than Caribbean, Indian or White residents.

    This field campaign funded the participation of scientists from seven different research groups and operated over thirty instruments during the Winter Intensive Operating Period (January-February 2012) of the Clean Air for London (ClearfLo) campaign. The campaign took place at a rural site in Detling, UK, 45 kilometers southeast of central London. The primary science questions for the ClearfLo winter IOP (intensive operational periods) were: 1) “what is the urban increment of particulate matter (PM) and other pollutants in the greater London area?” and 2) “what is the contribution of solid fuel use for home heating to wintertime PM?” An additional motivation for the Detling measurements was the question of whether coatings on black carbon particles enhance absorption.

  9. The epidemiology of suicide on the London Underground.

    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.

  10. 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

    Although dizziness is a common presenting symptom in general and hospital practice, its social cost is not known. We assessed the social and work life impact of dizziness on patients in two contrasting European cities, Siena and London. First, we developed the 'Social life & Work Impact of Dizziness questionnaire' (SWID), which was validated by administering it to 43 patients with dizziness and 45 normal controls and by correlating the results with the EQ-5D (Europe quality of life) questionnaire. The SWID and EQ-5D scores were worse in patients than controls (p < 0.001) and the two correlated significantly (r = 0.50 p < 0.001). Then two hundred consecutive patients per city attending tertiary specialised 'dizzy patient' clinics, one in London led by a neurologist, one in Siena led by an ear, nose and throat specialist (ENT), were investigated with SWID. Amongst the 400 patients, 27% reported changing their jobs and 21% giving up work as a result of the dizziness. Over 50% of patients felt that their efficiency at work had dropped considerably. The mean number of days off work attributed to the dizziness in the previous 6 months was 7.15 days. Social life was disrupted in 57% of all 400 patients. Factor analysis identified that detrimental effects on work, travel, social and family life combine to create a single factor accounting for much of the overall impact of their dizziness. Significant differences in some measures of handicap between London and Siena emerged, with London patients often faring worse. Reasons for these location differences include, as expected, a higher proportion of neurological patients in London than in Siena. However, factors related to city demographics and social cohesion may also modulate the impact on quality of life and working practice. Regardless of inter-city differences, these findings highlight the high social and economic impact of dizziness.

    2004-02-01

    Controlled trials conducted in the USA provide clear evidence that peer education can bring about a reduction in high risk sexual behaviour among gay men. HIV prevention interventions that systematically identified, recruited, trained and engaged popular opinion leaders (POLs) made a significant impact on sexual behaviour at a community level in small US towns. However, recent trials conducted in the UK have failed to replicate these findings. A POL intervention in London made no significant impact at a community level on the risk behaviours of gay men. Jeffrey Kelly, one of the authors of the US studies, has identified nine core elements central to the popular opinion leader model. In Kelly's view 'the UK projects were not tests of the popular opinion leader model because they did not employ most of these POL core elements'. The absence of any significant impact of the UK programmes on sexual risk behaviour at a community level was not, therefore, surprising. In fact, the London POL project incorporated all the core elements into its design and succeeded in employing seven out of nine in its delivery. Attempts to employ all the core elements, however, were hampered by problems in recruiting popular opinion leaders as well as barriers to communication. Process evaluation revealed that it was these obstacles which limited diffusion. This in turn explained the absence of any impact of the London POL project on sexual risk behaviour at a community level. The obstacles to successful diffusion in London have provided a valuable opportunity for examining the processes that underlie the POL model. Our study raises the question as to whether social interventions shown to be effective in one setting, place or moment in time can be replicated in another.

  10. 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.

    2014-05-01

    ClearfLo is a large multi-institutional project funded by the UK Natural Environment Research Council (NERC). ClearfLo established integrated measurements of meteorology, gaseous and particulate composition/loading of London's (UK) urban atmosphere in 2011 and 2012 to understand the processes underlying poor air quality. A new and unique long-term measurement infrastructure was established in London at street level, urban background and elevated sites and contrasted against rural locations to determine the urban increment in meteorology and pollution. This approach enables understanding the seasonal variations in the meteorology and composition together with the controlling processes. In addition two intensive observation periods (IOPs) provide more detail in winter 2012 and during the Olympics in summer 2012 focusing upon the vertical structure and evolution of the urban boundary layer, chemical controls on nitrogen dioxide and ozone production, in particular the role of volatile organic compounds, and processes controlling the evolution, size, distribution and composition of particulate matter. In this talk we present early analysis of the meteorology and air quality measurements within ClearfLo. In particular we show measurements that indicate the dominant regimes of London's boundary layer.

  12. The making of urban 'healtheries': the transformation of cemeteries and burial grounds in late-Victorian East London.

    PubMed

    Brown, Tim

    2013-10-01

    This paper focuses on the conversion of disused burial grounds and cemeteries into gardens and playgrounds in East London from around the 1880s through to the end of the century. In addition to providing further empirical depth, especially relating to the work of philanthropic organisations such as the Metropolitan Public Gardens Association, the article brings into the foreground debates regarding the importance of such spaces to the promotion of the physical and moral health of the urban poor. Of particular note here is the recognition that ideas about the virtuous properties of open, green space were central to the success of attempts at social amelioration. In addition to identifying the importance of such ideas to the discourse of urban sanitary reformers, the paper considers the significance of less virtuous spaces to it; notably here, the street. Building on Driver's work on 'moral environmentalism' and Osborne and Rose's on 'ethicohygienic space,' this paper goes on to explore the significance of habit to the establishing of what Brabazon called 'healtheries' in late-Victorian East London.

    Contemporaneous with John Snow's famous study of the 1854 London cholera epidemic were 2 other investigations: a local study of the Broad Street outbreak and an investigation of the entire epidemic, undertaken by England's General Board of Health. More than a quarter-century prior to Koch's description of Vibrio comma, a Board of Health investigator saw microscopic "vibriones" in the rice-water stools of cholera patients that, in his later life, he concluded had been cholera bacilli. Although this finding was potential evidence for Snow's view that cholera was due to a contagious and probably live agent transmitted in the water supply, the Board of Health rejected Snow's conclusions. The Board of Health amassed a huge amount of information which it interpreted as supportive of its conclusion that the epidemic was attributable not so much to water as to air. Snow, by contrast, systematically tested his hypothesis that cholera was water-borne by exploring evidence that at first glance ran contrary to his expectations. Snow's success provides support for using a hypothetico-deductive approach in epidemiology, based on tightly focused hypotheses strongly grounded in pathophysiology.

    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.

    The 7 July 2005 bombings in London caused heightened levels of distress among some in the general community. This distress was most notable in Muslims and members of ethnic minority groups. These effects were transient for most. An estimated 30% of those who were more affected by the attacks, including victims and witnesses, developed psychiatric disorders as a result. An outreach program was set up to screen those who were exposed to potentially traumatic events and to offer them evidence-based treatment. This article discusses what lessons might be learned from studies of the general community and the screen-and-treat approach.

    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.

    The London-moment readout has been observed in flight quality gyroscopes and it has been demonstrated that it is possible to reduce magnetic field trapped in these gyroscopes to levels as low as 1.5 x 10 exp -11 T. A preliminary analysis shows that the horizontal component of the London-moment signal is 60 percent of the total expected London-moment signal and is proportional to the gyro spin speed. Experiments were carried out in a unique ground test facility which was designed to provide the conditions necessary to observe the London moment of the spinning gyroscope.

    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.

    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.

  1. On the exchange-hole model of London dispersion forces

    NASA Astrophysics Data System (ADS)

    Ángyán, János G.

    2007-07-01

    First-principles derivation is given for the heuristic exchange-hole model of London dispersion forces by Becke and Johnson [J. Chem. Phys. 122, 154104 (2005)]. A one-term approximation is used for the dynamic charge density response function, and it is shown that a central nonempirical ingredient of the approximate nonexpanded dispersion energy is the charge density autocorrelation function, a two-particle property, related to the exchange-correlation hole. In the framework of a dipolar approximation of the Coulomb interaction around the molecular origin, one obtains the so-called Salem-Tang-Karplus approximation to the C6 dispersion coefficient. Alternatively, by expanding the Coulomb interaction around the center of charge (centroid) of the exchange-correlation hole associated with each point in the molecular volume, a multicenter expansion is obtained around the centroids of electron localization domains, always in terms of the exchange-correlation hole. In order to get a formula analogous to that of Becke and Johnson, which involves the exchange-hole only, further assumptions are needed, related to the difficulties of obtaining the expectation value of a two-electron operator from a single determinant. Thus a connection could be established between the conventional fluctuating charge density model of London dispersion forces and the notion of the "exchange-hole dipole moment" shedding some light on the true nature of the approximations implicit in the Becke-Johnson model.

    The first phase of an innovative combined heat and power (CHP) system for the City of London is now almost complete and should be operating at full capacity by the end of 1994. Test runs are taking place. The system is powered by two large 18-cylinder Waertsilae Vasa 46GD multifuel engines developing a total of just under 32 MW of power. The engines drive ABB Stromberg HSG 160O water-cooled generators with electrical efficiencies exceeding 97%. The station will use natural gas and heavy fuel oil to generate electricity for the grid, hot water for district heating and chilled water for air conditioning. In the first phase of the project, underground pipework and cabling will connect the power station to various buildings in the City including the Barbican Center, Guildhall and the Museum of London/Bastion House. State-of-the-art emission control equipment has been installed to reduce NO[sub x] and SO[sub 2] by over 90%. 5 figs.

    A programme of incentives was set up in the London Initiative Zones to improve primary care in inner London based on the findings of the Tomlinson Enquiry in 1992. This descriptive study is a 4-y time series analysis of changes in general practice structure in East London as the result of London Initiative Zone investment, and an exploration of the possible effect of investment on practice performance. We used routinely available administrative data for the whole analysis. General practice characteristics and two selected performance indicators: the asthma prophylaxis to bronchodilator ratio and cervical cytology screening rate, for all practices in the East London and the City Health Authority for 4 y, 1993-1996, were used. Both reflect practice efficiency, but relate to different aspects of practice performance. The prescribing indicator is more indicative of the quality of clinical practise, whereas cervical screening coverage relates more to the characteristics of the practice population and to practice organisation. Repeated measures analyses were used to identify trends and to explore the relationship between changes in practice characteristics and performance. Graphical methods were used to compare East London trends with the rest of England. There were significant improvements in practice structure as the consequence of London Initiative Zone investment. There was a positive association with improvements in practice performance, but East London still lagged some way behind national patterns. The findings suggest that while improvements in asthma prescribing follow the national trend, practices have difficulty in achieving and sustaining the 80% target for cervical cytology screening, and that an overall population coverage of 80% may be in doubt.Increased investment in practice staffing may be influential in improving some aspects of performance. However, in common with other inner cities, a greater effort and more innovative strategies may be needed to

    Winstanley, J

    2001-01-01

    William Briggs, MD, established himself as one of the first ophthalmic physicians, whom today we would call a neuro-ophthalmologist, to practice in the United Kingdom. After graduating with an MD from Cambridge in 1677, and while a Fellow of Corpus Christi College, he carried out original studies in visual anatomy and physiology. He described and named the optic papilla and the retinal nerve fibers in his book Ophthalmographia, published in 1676. He published his New Theory of Vision in 1682. While at Cambridge, he was a contemporary and a friend of Isaac Newton, with whom Briggs worked but who, in matters of visual anatomy and physiology, came to reach different conclusions from Briggs. In 1683, Briggs came to London to practice as a physician at St. Thomas' Hospital, where he established a considerable reputation as an ophthalmologist. For political reasons he was forced to resign from the Hospital prematurely.

    Interoception is the sensing of physiological signals originating inside the body, such as hunger, pain and heart rate. People with greater sensitivity to interoceptive signals, as measured by, for example, tests of heart beat detection, perform better in laboratory studies of risky decision-making. However, there has been little field work to determine if interoceptive sensitivity contributes to success in real-world, high-stakes risk taking. Here, we report on a study in which we quantified heartbeat detection skills in a group of financial traders working on a London trading floor. We found that traders are better able to perceive their own heartbeats than matched controls from the non-trading population. Moreover, the interoceptive ability of traders predicted their relative profitability, and strikingly, how long they survived in the financial markets. Our results suggest that signals from the body - the gut feelings of financial lore - contribute to success in the markets. PMID:27641692

    Cervical ribs are an important cause of neurovascular compression at the thoracic outlet. Previous studies have shown the prevalence of cervical ribs to be between 0.05 and 3%, depending on the sex and race of the population studied. We examined 1,352 chest radiographs to determine the prevalence of cervical ribs in a London population of mixed sex and ethnicity. Our study found that the overall prevalence of cervical ribs was 0.74% with a higher rate in females compared with males (1.09 and 0.42%, respectively). Of the 10 individuals with a cervical rib, five were on the left, three were on the right and two were bilateral. The presence of elongated C7 transverse processes (transverse apophysomegaly) was also noted. We found a total of 30 elongated transverse processes with an overall prevalence of 2.21%. They were also more common in females (3.43%) than males (1.13%).

    2013-06-01

    Evidence suggests that 20 mph zones are an effective intervention to reduce casualties from road traffic crashes in urban areas. This analysis compares the costs of construction of the 20 mph zone intervention in high and low casualty areas in London to the value of casualties avoided over 5 and 10 year time horizons. Probabilistic sensitivity analyses were conducted to quantify uncertainty in the results associated with model parameters. Results indicate a net present value (NPV) of £18 947 (90% credible limits -£75 252 to £82 021 2005 prices) after 5 years and £67 306 (£-29 157 to £137 890) after 10 years when 20 mph zones are implemented in areas with one or more casualty per kilometre of road. Simulations from our model suggest that the 'threshold of casualties' where NPVs become positive using a 10 year time horizon is 0.7 casualties per kilometre.

    2009-01-01

    In this article, the author details the experiences of his hospital and other London hospitals in treating brachial plexus injury. As noted, important advances have been made in methods of diagnosis and repair. Myelography was replaced by CT scan and later by MRI. Among the topics the author explores are diagnosis (including pain, the presence or absence of the Tinel sign, and the irradiation of pins and needles) and the principles of repair. The author emphasizes that it is imperative that ruptured nerves be repaired as soon as possible, with the closed traction lesion coming, in urgency, close behind reattachment of the amputated hand or repair of a great artery and a trunk nerve in the combined lesion. Finally, the article concludes that the surgeon must be actively engaged in the whole process of rehabilitation and treatment of pain. This is part of a Point-Counterpoint discussion with Dr. David G. Kline's presentation of "A Personal Experience."

    2002-11-01

    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.

    2013-04-01

    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

  7. SETI and astrobiology: The Rio Scale and the London Scale

    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.

    Epiphytic lichen and bryophyte distribution and frequency were investigated on the trunks of 145 young oak trees throughout London and surrounding counties, and compared with pollution levels and bark pH. Sixty-four lichen and four bryophyte species were recorded. Three major zones were identified: (i) two central regions with a few lichens, bryophytes absent; (ii) a surrounding region with a more diverse flora including a high cover of nitrophyte lichens; and (iii) an outer region, characterised by species absent from central London, including acidophytes. Nineteen species were correlated with nitrogen oxides and 16 with bark pH, suggesting that transport-related pollution and bark acidity influence lichen and bryophyte distribution in London today. Lichens and bryophytes are responding to factors that influence human and environmental health in London. Biomonitoring therefore has a practical role to assess the effects of measures to improve London's air quality.

    The Well London programme was launched across twenty boroughs in London during late 2007 to improve the health and well-being of residents living in some of the most deprived communities in London. Well London employed a multi-stage community engagement process which informed the overall project strategy for each intervention area. In this article we establish and describe the key principles that guided the design of this innovative community engagement process. Principles included building collaborative partnerships, working with whole-systems, privileging community knowledge and working with the deficit of experience in each area. The article then describes in detail how these principles were operationalised throughout the preparation and delivery of forty World Cafes, which were the first open community activities of the Well London community engagement process. Finally, this article reflects on and summarises the lessons learned when employing innovative, inclusive and transparent community engagement for health promotion. PMID:27857453

    OBJECTIVE: To describe the impact of HIV on mortality in men and women aged 15-54 in London. DESIGN: Combination of routine mortality statistics with reports of AIDS deaths adjusted for underreporting and change in address from time of report to time of death. Calculation of standardised mortality ratios (SMRs) for males including and excluding HIV comparing inner London and outer London with the rest of England and Wales. METHODS: Comparison of trends in all cause mortality and SMRs in males over time. Comparison of trends in HIV related deaths with other main causes of deaths in males and females in London. RESULTS: Age standardised rates for the rest of England and Wales showed a continual decline from 1979 to 1996 but rates in inner London males (ages 15-54) stopped declining around 1984-5 leading to a considerable increase in the SMR for inner London from 127 for 1985-7 to 171 for 1994-6. SMRs excluding HIV related deaths for inner London, however, showed no significant change over this time. There was a fall in HIV related mortality in 1996, though HIV was still the leading cause of death in males and second leading cause of death in females in inner London, and the fourth commonest cause of death in males in outer London. CONCLUSION: These data are the first to indicate the impact of HIV on mortality within a significant population in England and Wales. They show that public health priorities in London are different from the rest of the country. Analyses of trends of all cause mortality in people under 65 may mislead unless they take account of HIV.

    Laboratory-based research aimed at understanding processes regulating insulin secretion and mechanisms underlying β-cell dysfunction and loss in diabetes often makes use of rodents, as these processes are in many respects similar between rats/mice and humans. Indeed, a rough calculation suggests that islets have been isolated from as many as 150,000 rodents to generate the data contained within papers published in 2009 and the first four months of 2010. Rodent use for islet isolation has been mitigated, to a certain extent, by the availability of a variety of insulin-secreting cell lines that are used by researchers world-wide. However, when maintained as monolayers the cell lines do not replicate the robust, sustained secretory responses of primary islets which limits their usefulness as islet surrogates. On the other hand, there have been several reports that configuration of MIN6 β-cells, derived from a mouse insulinoma, as three-dimensional cell clusters termed ‘pseudoislets’ largely recapitulates the function of primary islet β-cells. The Diabetes Research Group at King’s College London has been using the MIN6 pseudoislet model for over a decade and they hosted a symposium on “Pseudoislets as primary islet replacements for research”, which was funded by the UK National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3Rs), in London on 15th and 16th April 2010. This small, focused meeting was conceived as an opportunity to consolidate information on experiences of working with pseudoislets between different UK labs, and to introduce the theory and practice of pseudoislet culture to laboratories working with islets and/or β-cell lines but who do not currently use pseudoislets. This short review summarizes the background to the development of the cell line-derived pseudoislet model, the key messages arising from the symposium and emerging themes for future pseudoislet research.

  13. Urban inoculation and the decline of smallpox mortality in eighteenth‐century cities—a reply to Razzell†

    2015-01-01

    Smallpox was probably the single most lethal disease in eighteenth‐century Britain but was reduced to a minor cause of death by the mid‐nineteenth century due to vaccination programmes post‐1798. While the success of vaccination is unquestionable, it remains disputed to what extent the prophylactic precursor of vaccination, inoculation, reduced smallpox mortality in the eighteenth century. Smallpox was most lethal in urban populations, but most researchers have judged inoculation to have been unpopular in large towns. Recently, however, Razzell argued that inoculation significantly reduced smallpox mortality of adults and older children in London in the last third of the eighteenth century. This article uses demographic evidence from London and Manchester to confirm previous findings of a sudden fall in adult smallpox mortality and a rise in the importance of smallpox in early childhood c. 1770. The nature of these changes is consistent with an increase in smallpox transmission in London and Manchester after 1770 and indicates that smallpox inoculation was insufficient to reduce smallpox mortality in large towns. It remains unclear whether inoculation could have operated to enhance smallpox transmission or whether changes in the properties of the smallpox virus drove the intensification of smallpox mortality among young children post‐1770.

  14. Medical Practice, Urban Politics and Patronage: The London ‘Commonalty’ of Physicians and Surgeons of the 1420s *

    PubMed Central

    Ralley, Robert

    2015-01-01

    Medical practice in fifteenth-century England is often seen as suffering from the low status and unregulated practice of which Thomas Linacre later complained. Unlike in many European cities, the provision of physic was uncontrolled, and while urban guilds oversaw surgery as a manual art, no comprehensive system of medical organisation or regulation existed. However, in a remarkable episode of the 1420s, a group of university-trained physicians and elite surgeons associated with Humphrey, Duke of Gloucester, briefly established just such a system. While their efforts initially secured approval for a national scheme, it was only in the City of London that they succeeded in implementing their plans. The detailed ordinances of the collegiate ‘commonalty’ they founded provide a unique insight into their attitudes. Drawing on continental models, they attempted to control all medicine within the city by establishing a hierarchy of practitioners, preventing illicit and incompetent practice, and offering treatment to even the poorest Londoners. Yet they failed to appreciate the vested interests of civic politics: achieving these aims meant curtailing the rights of the powerful Grocers and the Barbers, a fact made clear by their adjudication of a case involving two members of the Barbers’ Company, and the Barbers’ subsequent riposte—a mayoral petition that heralded the commonalty’s end. Its founder surgeons went on to revitalise their Surgeons’ Fellowship, which continued independently of the Barbers until a merger in 1540; in contrast, the physicians withdrew from civic affairs, and physic remained entirely unregulated until episcopal licensing was instituted in 1511.

    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.

    2004-02-01

    Internal and external noise surveys have been carried out around schools in London, UK, to provide information on typical levels and sources to which children are exposed while at school. Noise levels were measured outside 142 schools, in areas away from flight paths into major airports. Here 86% of the schools surveyed were exposed to noise from road traffic, the average external noise level outside a school being 57 dB L(Aeq). Detailed internal noise surveys have been carried out in 140 classrooms in 16 schools, together with classroom observations. It was found that noise levels inside classrooms depend upon the activities in which the children are engaged, with a difference of 20 dB L(Aeq) between the "quietest" and "noisiest" activities. The average background noise level in classrooms exceeds the level recommended in current standards. The number of children in the classroom was found to affect noise levels. External noise influenced internal noise levels only when children were engaged in the quietest classroom activities. The effects of the age of the school buildings and types of window upon internal noise were examined but results were inconclusive.

  17. The London polonium incident: lessons in risk communications.

    Rubin, G James; Amlôt, Richard; Page, Lisa

    2011-11-01

    Public responses to large-scale radiological incidents are often thought to be disproportionate to the objective risk and can involve widespread societal disruption. Recent experiences of the (200)Po incident in central London suggest that public responses depend heavily on the nature of the incident and the effectiveness of risk communication efforts. This paper describes the outcome of several studies done in the aftermath of the (200)Po incident that suggest the reaction of the public on this occasion was muted, even for those directly affected. However, the desire for accurate, up-to-date and individually-tailored information was strong, and satisfaction with the efforts of the responding agencies was mediated by this information provision. A small minority of individuals was difficult to reassure effectively. This group may confer a particular drain on resources. Lessons for the risk communication efforts of public health responders are identified, in particular the importance of helping individuals to identify their risk of exposure, understand the difference between acute and chronic effects of exposure, and appreciate the meaning of any test results. Attempts at providing reassurance in the absence of specific information are likely to be counterproductive in any future radiological incident.

  18. Geological Society of London Issues Statement on Climate Change

    2011-02-01

    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.”

    Twenty girls between 10 and 13 years of age, studying at a residential school were randomly assigned to two groups. One group practiced yoga for one hour fifteen minutes per day, 7 days a week, while the other group was given physical training for the same time. Time for planning and for execution and the number of moves required to complete the Tower of London task were assessed for both groups at the beginning and end of a month. These three assessments were separately tested in increasingly complex tasks requiring 2-moves, 4-moves and 5-moves. The pre-post data were compared using the Wilcoxon paired signed ranks test. The yoga group showed a significant reduction in planning time for both 2-moves and 4-moves tasks (53.9 and 59.1 percent respectively), execution time in both 4-moves and 5-moves tasks (63.7 and 60.3 percent respectively), and in the number of moves in the 4-moves tasks (20.9 percent). The physical training group showed no change. Hence yoga training for a month reduced the planning and execution time in simple (2-moves) as well as complex tasks (4, 5-moves) and facilitated reaching the target with a smaller number of moves in a complex task (4-moves).

    The London Cord Blood Bank was established with the aim of collecting, processing and storing 10000 unrelated stem cell donations for the significant number of children in the UK requiring transplantation, for whom a matched unrelated bone marrow donor cannot be found. Collection is performed at two hospitals by dedicated cord blood bank staff after delivery of the placenta. Mothers are interviewed regarding medical, ethnic and behavioural history by nurse counsellors and sign a detailed consent form. Donations are returned to the bank for processing. Volume reduction is undertaken by a simple, closed, semi-automated blood processing system, with excellent recovery of progenitor cells. Units are cryopreserved and stored in the vapour phase of liquid nitrogen. Blood samples from mothers and cord blood donations are tested for the UK mandatory red cell and microbiology markers for blood donors. Donations are typed for HLA-A, B and DR at medium resolution (antigen split) level using sequence-specific oligonucleotide probing and sequence-specific priming techniques. The selection of collection hospitals on the basis of ethnic mix has proven effective, with 41.5% of donations derived from non-European caucasoid donors. Bacterial contamination of collections has been dramatically reduced by implementation of improved umbilical cord decontamination protocols.

    Sulfate aerosols exert profound impacts on human and ecosystem health, weather, and climate, but their formation mechanism remains uncertain. Atmospheric models consistently underpredict sulfate levels under diverse environmental conditions. From atmospheric measurements in two Chinese megacities and complementary laboratory experiments, we show that the aqueous oxidation of SO2 by NO2 is key to efficient sulfate formation but is only feasible under two atmospheric conditions: on fine aerosols with high relative humidity and NH3 neutralization or under cloud conditions. Under polluted environments, this SO2 oxidation process leads to large sulfate production rates and promotes formation of nitrate and organic matter on aqueous particles, exacerbating severe haze development. Effective haze mitigation is achievable by intervening in the sulfate formation process with enforced NH3 and NO2 control measures. In addition to explaining the polluted episodes currently occurring in China and during the 1952 London Fog, this sulfate production mechanism is widespread, and our results suggest a way to tackle this growing problem in China and much of the developing world.

    1984-04-01

    The livers of 531 captive wild birds necropsied at the Zoological Society of London were examined histologically. Marked fatty infiltration of the liver was found in 13 cases. Seven of the 13 cases were from the order Psittaciformes indicating that some species (cockatoos, parakeets and parrots) in this order may be particularly susceptible to fatty infiltration of the liver. Affected livers were commonly swollen or enlarged, pale, white or yellow in colour and soft, friable or fatty at post mortem examination. Histologically, marked fatty infiltration of the liver was characterised by the presence of intracytoplasmic fat vacuoles within hepatocytes without zonal or lobular distribution throughout the sections examined. Reticulolysis and fibrosis of the hepatic parenchyma were found in association with marked fatty liver in a proportion of cases. Macroscopic or histological evidence of hepatic haemorrhages was not found in affected birds. In psittacine birds, obesity was frequently seen at post mortem examination and it was considered that nutritional and/or metabolic factors were important causes of fatty liver in this group. Fatty liver was found in association with chronic wasting diseases caused by mycotic infection in two cases.

    A vertical conduction current arises from the global ionospheric potential and the integrated electrical resistance between the Earth's surface and the ionosphere. The conduction current density varies with the ionospheric potential and the vertical (columnar) resistance. At the surface, the conduction current density is known as the air-earth current. C.T.R. Wilson developed a measurement technique for the air-earth current in 1906, which was implemented by the British Meteorological Office at its Kew Observatory (51° 28'N, 0° 19'W) near London in 1909. Simultaneous measurements of air-earth current, potential gradient and positive air conductivity were made almost continuously until 1979 using the Wilson method on fine afternoons. A summary of the complete set of monthly mean measurements is presented here for the first time. The data span the nuclear weapons testing period and the UK Clean Air Act of 1956, both of which influenced the measurements obtained. Annual average values of the air earth current density at Kew are 0.97 pA·m -2 (1909-1931), 1.04 pA·m -2 (1932-1949) and 1.41 pA·m -2 (1967-1979).

    Background The study was carried out to determine the prevalence of orthodontic treatment need in children from minority ethnic groups and compare the need to the white population. The second objective was to explore variations in agreement between subjective and objective treatment need in a multiethnic context using the aesthetic component of Orthodontic Treatment Need Index (IOTN AC). Methods A cross-sectional study in North West London, 14 schools were randomly selected from the 27 schools in the two boroughs of Harrow and Hillingdon. Comparison between objective and subjective treatment need was carried out using IOTN AC index. Clinical orthodontic treatment need was also recorded using the dental health component of Orthodontic Treatment Need Index (IOTN DHC). Results 2,788 children were examined and completed the questionnaire. 16% of the study population were already wearing appliances or had finished orthodontic treatment. Of the remaining children; 15% had definite need for treatment using the dental health component of the IOTN. There was no significant variation in the need for orthodontic treatment between different ethnic backgrounds (P > 0.05) whether using the AC or DHC components of the IOTN index. However, poor agreement was detected between professional and subjective assessment of ethnic minority of orthodontic treatment need using IOTN AC index. Conclusion Orthodontic treatment need in children of ethnic minorities does not differ significantly from the vast majority of white children. However treatment need based on aesthetic index continues to vary in all ethnic groups from the professional aesthetic assessment PMID:16188024

    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.

    Purpose The clinical presentation and epidemiology for patients with enteric fever at two hospitals in East London during 2007–2012 is described with the aim to identify preventive opportunities and to reduce the cost of treatment. 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

    Objectives To seek community pharmacists' perception on use, safety and possible effectiveness of e-cigarettes as quit smoking tools, and their future regulation. Setting A survey of a sample of 154 community pharmacies across London, UK. Context E-cigarettes have exclusively established themselves in the market through consumers-led demand. To date, e-cigarettes still remain unregulated and can be easily purchased in shops, over the internet, but more controversially also in pharmacies in the UK. Pharmacists find themselves with a shortage of information on their safety and efficacy, and may experience an ethical dilemma when consulted by patients/customers. Key findings Response rate: 60% (n=92). Independent pharmacies accounted for 90% of the sample. The majority of participants (73%) sell e-cigarettes. A minority of participants (20%) have been presented with adverse effects such as cough and dry mouth. As possible reasons for their use, pharmacists ranked ‘aid in stop smoking’ as the most important (56%), with ‘cheaper alternative’ (43%) and ‘social/recreational use’ (31%) being the least important ones. Safety issues were raised as statements such as ‘e-liquid in cartridges may be toxic’ were agreed by 52% of respondents. The majority of pharmacists (97%) were supportive of e-cigarettes being regulated, expressing current concerns regarding excipients (42%) and nicotine content (34%). Participants indicated that they would require training in the form of information packs (88%), online tutorials (67%), continuous professional development (CPD) workshops (43%) to cover safety, counselling, dosage instructions, adverse effects and role in the smoking cessation care pathway in the future. Conclusions Pharmacists expressed concerns about the safety of e-cigarettes, especially regarding the amounts of excipients and nicotine as these still remain unregulated. Currently, there are no guidelines for pharmacists regarding e-cigarettes. Community

    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

    Forty-eight students kept a log diary of activities during their central London general practice teaching attachments associated with the Department of Primary Health Care of University College and Middlesex School of Medicine. The students each saw on average 96 patients per week, of whom 69% were discussed by the general practitioner with the student after the consultation. Students spent an average of 21.5 hours a week sitting in with the general practitioner. While most of this time was as a passive observer, the students were also able to participate more actively, personally taking histories for a median of 1.25 hours a week and personally examining patients for a median of 1.7 hours a week. During these periods of active involvement each student personally took a mean of 10 short and 2.5 long histories per week and performed a mean of 25.5 short and 1.2 long examinations per week. General practitioners to whom the students were attached spent a mean of 4 hours a week on (patient-oriented) teaching. The tuition was highly rated by the students in terms of both usefulness and stimulation. Students also received a mean of 2.3 hours a week of teaching from other members of the primary health care team, which was somewhat less well received. Areas for improvement were: the relatively few home visits (median of 6 per week) per student; the limited time students spent on self-education (average of 65 minutes per week); and the few practical procedures performed by the students. Students could also be encouraged to play a more active role in examining and interviewing patients.

    Treponematosis is a syndrome of chronic infectious diseases. There has been much debate on its origins and spread, particularly with regard to venereal syphilis, an unsightly and debilitating disease in preantibiotic populations. The osteological analysis of 5,387 individuals excavated by Museum of London Archaeology from the medieval burial ground of St. Mary Spital in London (dated c 1120-1539) provided an unprecedented opportunity to investigate the nature and prevalence of disease over a period of time. Twenty-five individuals were found with suspected treponematosis, originating from all but the earliest period of the burial ground. Descriptions of affected individuals from each period, together with supporting images, are provided. In this work, particular emphasis was given to the distribution of lesions on the skeleton and the variation in patterns by sex and over time. Little change was observed in the distribution of bony change between individuals dated to pre- and post-Columbian periods. However, a dramatic rise in the prevalence of the disease in the final period (c 1400-1539) may reflect documentary reports of a European epidemic from the late 15th century.

    Pb isotope compositions of biologically significant PM(10) atmospheric particulates from a busy roadside location in London UK were measured using solution- and laser ablation-mode MC-ICP-MS. The solution-mode data for PM(10) sampled between 1998-2001 document a dramatic shift to increasingly radiogenic compositions as leaded petrol was phased out. LA-MC-ICP-MS isotope analysis, piloted on a subset of the available samples, is shown to be a potential reconnaissance analytical technique. PM(10) particles trapped on quartz filters were liberated from the filter surface, without ablating the filter substrate, using a 266 nm UV laser and a dynamic, large diameter, low-fluence ablation protocol. The Pb isotope evolution noted in the London data set obtained by both analytical protocols is similar to that observed elsewhere in Western Europe following leaded petrol elimination. The data therefore provide important baseline isotope composition information useful for continued UK atmospheric monitoring through the early 21(st) century.

    2010-01-21

    The evolution of damage to building materials has been estimated for the 21st century, with a particular focus on aluminum, zinc, copper, plastic, paint, and rubber in urban areas. We set idealized air pollution and climates to represent London and Prague across the period 1950-2100. Environmental parameters were used to estimate future recession, corrosion, and loss of properties through published damage or dose-response functions. The 21st century seems to provide a less aggressive environment for stone and metals than recent times. Improvements in air quality are the most relevant drivers for this amelioration. Changes in climate predicted for the 21st century do not alter this picture. On the other hand, polymeric materials, plastic, paint, and rubber might show slightly increased rates of degradation, to some extent the result of enhanced oxidant concentrations, but also the possibility of contributions from more solar radiation.

    THE ANCIENT TIMES: Many early civilisations left testimonies about ancient times and resuscitation, as well. Some of them did it successfully and some of them did it less successfully; however, all of them wished to help a dying person and to bring him back to life. The first trustworthy note can be found in the Bible--Old Testament as a very realistic description of resuscitation of a child. THE MIDDLE AGES: The medieval scientists, Paracelsus and Vesalius, described first successful resuscitation attempts in the 15th and 16th century. These two men successfully applied ventilation methods by air inflation with blacksmith bellows. THE MODERN ERA: The first defibrillation was recorded in the 18th century in England, which was conducted by one of the volunteer society members. With the development of mechanics and techniques, the first precursors of modern respirators were introduced in the 19th century. The age of modern cardiopulmonary resuscitation began in the middle of 20th century, when Dr Peter Safar brought in the combination of artificial ventilation and chest compressions as the standard for implementing resuscitation. Adrenalin and defibrillation were introduced into the resuscitation techniques by Dr Redding and Dr Kouwenhaven, respectively; thus beginning the advance life support administration, which has been applied, with minor changes, until today.

    Mauck, Aaron

    2012-01-01

    This article examines the career and reform agenda of Christopher Merrett as a means of evaluating the changing conditions of medical knowledge production in late seventeenth-century London. This period was characterised by increasing competition between medical practitioners, resulting from the growing consumer demand for medical commodities and services, the reduced ability of elite physicians to control medical practice, and the appearance of alternative methods of producing medical knowledge – particularly experimental methods. This competition resulted in heated exchanges between physicians, apothecaries, and virtuosi, in which Merrett played an active part. As a prominent member of both the Royal Society and the Royal College of Physicians, Merrett sought to mediate between the two institutions by introducing professional reforms designed to alleviate competition and improve medical knowledge.These reforms entailed sweeping changes to medical regulation and education that integrated the traditional reliance on Galenic principles with knowledge derived from experiment and artisanal practices. The emphasis Merrett placed on the trades suggests the important role artisanal knowledge played in his efforts to reorganise medicine and improve knowledge of bodily processes. PMID:23752982

    This historical study analyzes 2 disasters in Texas in the early 20th century: the 1937 school explosion in New London and the 1947 Texas City ship explosion. Disaster narratives and commemoration activities are examined as means of healing and restoration after a catastrophic event. Specifically, this article discusses contextual factors of time and place, Coastal and East Texas between 1937 and 1947, and shows how these factors shaped the ways in which people made sense of their disaster experiences. This included not only the influence of geography but also economics, social position, racial characterizations, and religious beliefs. The article also considers conflicting and biased factors that can occur regarding time and place and how these factors influenced narrative constructions.

  4. Are the birch trees in Southern England a source of Betula pollen for North London?

    2009-01-01

    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.

    We investigate avoidable hospital conditions (AHC) in three world cities as a way to assess access to primary care. Residents of Hong Kong are healthier than their counterparts in Greater London or New York City. In contrast to their counterparts in New York City, residents of both Greater London and Hong Kong face no financial barriers to an extensive public hospital system. We compare residence-based hospital discharge rates for AHC, by age cohorts, in these cities and find that New York City has higher rates than Hong Kong and Greater London. Hong Kong has the lowest hospital discharge rates for AHC among the population 15-64, but its rates are nearly as high as those in New York City among the population 65 and over. Our findings suggest that in contrast to Greater London, older residents in Hong Kong and New York face significant barriers in accessing primary care. In all three cities, people living in lower socioeconomic status neighborhoods are more likely to be hospitalized for an AHC, but neighborhood inequalities are greater in Hong Kong and New York than in Greater London.

    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."

    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.

    We present the first gauge-origin-independent, frequency-dependent calculations of the hypermagnetizability anisotropy, which determines the temperature-independent contribution to magnetic-field-induced linear birefringence, the so-called Cotton-Mouton effect. A density-matrix-based scheme for analytical calculations of frequency-dependent molecular properties for self-consistent field models has recently been developed, which is also valid with frequency- and field-dependent basis sets. Applying this scheme to Hartree-Fock wave functions and using London atomic orbitals in order to obtain gauge-origin-independent results, we have calculated the hypermagnetizability anisotropy. Our results show that the use of London orbitals leads to somewhat better basis-set convergence for the hypermagnetizability compared to conventional basis sets and that London orbitals are mandatory in order to obtain reliable magnetizability anisotropies.

    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.

    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

    2012-01-01

    This article explores the potential for integrated cancer systems to improve the quality of care and deliver cost efficiencies and improve outcomes for cancer patients. Currently, patients in the UK still have poorer survival rates than comparable countries such as Canada, Sweden, Norway and Australia. Improving the quality of cancer services is a key policy objective and cancer is a priority outcome measure in both the NHS and Public Health Outcomes Framework. Evidence suggests that better integrated delivery has the potential to improve the quality and reduce the cost of healthcare, and ultimately improve health outcomes. One of the key themes from the Model of Care for Cancer Services1 was that cancer services should be commissioned along pathways and that provider networks should be established to deliver care. London has two integrated cancer systems; one covering north central and east London (London Cancer) and the other covering west and south London (London Cancer Alliance). There a number of areas in cancer care that the current model of service provision has failed to adequately address and which have the potential to improve significantly though implementation of integrated services. These include improving early diagnosis, reducing inequalities in access to treatment and outcomes and maximising research and training across the system. Important drivers for the integration of cancer services are strong clinical leadership, shared informatics systems, focusing on quality of services and improving patient experience. Emerging needs of integrated cancer in London are around strengthening the involvement of primary care, public health and the third sector; working to develop sufficient capacity and expertise in primary care and collaborating more closely with commissioners to develop integrated systems.

    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.

  14. Small area estimates of smoking prevalence in London. Testing the effect of input data.

    2012-05-01

    Small area estimates (SAEs) can provide information about health behaviour at small area levels that is otherwise not available. Because of its increasing use by policy makers, more attention needs to be paid to the reliability of these estimates. This paper reports on smoking prevalence data generated for London at the neighbourhood level using spatial microsimulation modelling. We test the reliability of smoking prevalence estimates at the neighbourhood level using different input datasets. The paper further underlines the importance of estimating health behaviours at the small area level, particularly in diverse cities such as London, where estimation at the city level can mask significant spatial differences.

  15. "Walking and watching" in queer London: Sarah Waters' Tipping The Velvet and The Night Watch.

    PubMed

    Wood, Rachel

    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.

  16. Occupation and cancer in London: an investigation into nasal and bladder cancer using the Cancer Atlas.

    PubMed

    Baxter, P J; McDowall, M E

    1986-01-01

    The Atlas of Cancer Mortality for England and Wales showed pronounced excesses of male mortality from nasal and bladder cancer in certain London boroughs. These excesses were investigated by case-referent studies using death certificate data for male deaths, 1968-78. Nasal cancer was found to be significantly associated with occupations involving heavy exposure to wood dust. Bladder cancer was significantly associated with occupations in road transport driving and in the handling of leather, whereas consistently raised relative risk ratios were also found for wood-workers, engineering fitters, printers, machinists, plumbers, and motor mechanics. These findings highlight the potential role of occupational factors in cancer causation in London.

  17. The sooterkin doctor: the London career of John Maubray, MD (1700-1732), "andro-boethogynist".

    PubMed

    Bates, A W

    2004-08-01

    Dr John Maubray (1700-1732) was one of the most prominent man-midwives of Georgian London. His emphasis on the importance of physical examination and a combination of theoretical and practical teaching seems to have foreshadowed later methods of training in midwifery. His espousal of the non-instrumental Deventerian system of obstetrics and his activities in the parish of St George's, Hanover Square in London, identified him with the dominant Whig party. Although he failed to acquire a major patron, his network of social connections enabled him to obtain charitable and public service appointments, culminating in his chairmanship of the Charitable Corporation.

  18. Tackling tuberculosis: Insights from an international TB Summit in London

    Tuberculosis (TB) poses a grave predicament to the world as it is not merely a scientific challenge but a socio-economic burden as well. A prime cause of mortality in human due to an infectious disease; the malady and its cause, Mycobacterium tuberculosis have remained an enigma with many questions that remain unanswered. The ability of the pathogen to survive and switch between varied physiological states necessitates a protracted therapeutic regimen that exerts an excessive strain on low-resource countries. To complicate things further, there has been a significant rise of antimicrobial resistance. Existing control measures, including treatment regimens have remained fairly uniform globally for at least half a century and require reinvention. Overcoming the societal and scientific challenges requires an increase in dialog to identify key regions that need attention and effective partners with whom successful collaborations can be fostered. In this report, we explore the discussions held at the International TB Summit 2015 hosted by EuroSciCon, which served as an excellent platform for researchers to share their recent findings. Ground-breaking results require outreach to affect policy design, governance and control of the disease. Hence, we feel it is important that meetings such as these reach a wider, global audience.

    A legacy emphasis was one of the fundamental pillars of the London 2012 Olympic Games. The notion of an Olympic legacy was predicated on assumptions that the event's value would not purely derive from the sporting spectacle, but rather from the "success" of enduring effects met out in London and across the country.

    2013-01-01

    An interview study of 44 Bangladeshi patients and relatives in eastern London demonstrated frequent appeals to God and deprecation of personal agency. This paper offers an interpretation of this apparent 'fatalism', which argues for the logical downplaying of human agency and ambition in archaic Arabia, contemporary rural Sylhet and among first generation Sylheti migrants in London.

  3. The development of forensic medicine in the United Kingdom from the 18th century.

    PubMed

    Eckert, W

    1992-06-01

    Forensic medicine in the United Kingdom includes both forensic pathology and clinical forensic medicine on the living. It began at the end of the 18th century, long after its development in Germany, Italy, France, and other countries in Europe. Initial beginnings were in Scotland, where a program began at the University of Edinburgh with the establishment of a chair in Forensic Medicine by Prof. Andrew Duncan Sr. The development in England began in London's Kings College Medical School with a chair held by Prof. William A. Guy. Later chairs in Forensic Medicine were established in Glasgow, Aberdeen, and in London, where Forensic Medicine was taught at St. Mary's Hospital Medical School, Guy's Hospital Medical School, London Hospital Medical School, Charing Cross Hospital Medical School, St. Thomas Hospital Medical School, and St. George's Hospital Medical School. In other cities in England, Wales, and Northern Ireland, departments were founded in Leeds, Manchester, Cardiff, and Belfast. Many textbooks were prepared during this time by professors from these medical schools and by others working in nonacademic areas. The development of coroner activities and those of the police surgeons is also part of the study of forensic medicine.

  8. A view from the streets: women and medical work in Elizabethan London.

    PubMed

    Harkness, Deborah E

    2008-01-01

    In Elizabethan London, women occupied a significant position in the city's medical marketplace, both as consumers of medical services and as practitioners. Though male medical authors of the period objected to the presence and practices of these women, a very different view of their medical work emerges if we shift our historical vantage point to the streets, houses, churches, and hospitals of the city. Using relatively underutilized sources such as parish records, probate records, lists of immigrants to London, hospital records, and individual manuscripts it is possible to draw a richer, more detailed portrait of how female health-care workers engaged with the business of health and healing. Women emerge from these records as active, prominent, and acknowledged participants in the delivery of services that promoted and preserved the health of many Londoners from cradle to grave. Hired by public institutions such as parishes and hospitals, as well as by private individuals, women were central figures in the delivery of nursing, medical, pharmaceutical, and surgical services throughout the city as part of organized systems of health care. Exploring how Londoners saw female practitioners, and how women played a recognized role within the city's range of health-care options, demonstrates that women were crucial to community health, and were also valued as such by their neighbors and patients.

    MacAllister, William S; Bender, H Allison; Whitman, Lindsay; Welsh, Antoinette; Keller, Shari; Granader, Yael; Sherman, Elisabeth M S

    2012-01-01

    Children and adolescents with epilepsy are known to demonstrate executive function dysfunction, including working memory deficits and planning deficits. Accordingly, assessing specific executive function skills is important when evaluating these individuals. The present investigation examined the utility of two measures of executive functions-the Tower of London and the Behavioral Rating Inventory of Executive Functioning (BRIEF)-in a pediatric epilepsy sample. Ninety clinically referred children and adolescents with seizures were included. Both the Tower of London and BRIEF identified executive dysfunction in these individuals, but only the Tower of London variables showed significant relations with epilepsy severity variables such as age of epilepsy onset, seizure frequency, number of antiepileptic medications, etc. Further, the Tower of London and BRIEF variables were uncorrelated. Results indicate that objective measures of executive function deficits are more closely related to epilepsy severity but may not predict observable deficits, as reported by parents. Comprehensive evaluation of such deficits, therefore, should include both objective measures as well as subjective ratings from caregivers.

    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.

    In 1886, addressing the nascent American Society of Mechanical Engineers, Henry R. Towne proposed that "the management of works" be considered a modern art--thereby heralding the Management Century, when management as we know it came into being and shaped the world in which we work. Kiechel, a past editorial director of Harvard Business Publishing, elucidates the three eras that punctuate this period: the years leading up to World War II, during which scientific exactitude gave wings to a new managerial elite; the early postwar decades, managerialism's apogee of self-confidence and a time when wartime principles of strategy were adapted, sometimes ruthlessly, to the running of companies; and the 1980s to the present, years that saw fast-moving changes, disequilibrium, and a servitude to market forces but also ushered in globalism, unprecedented innovation, and heightened expectations about how workers are to be treated. Along the way he examines the contributions of thinkers such as Frederick Taylor, Elton Mayo, Peter Drucker, and Michael Porter. What lies ahead? Perhaps the biggest challenge facing the 21st-century company, Kiechel posits, is to truly free the spark of human imagination from the organization's tidal pull toward the status quo. There's almost always a better way, he concludes--and management will continue to seek it.

    Urban air pollution has been particularly studied for the last few decades because of its recognised environmental dangers and health implications. The complexity of the urban surface characteristics and turbulence patterns has dictated the use of numerical models by environmental research agencies and regulators in order to predict and manage urban air pollution. However, most of these models are not specifically adapted to urban applications and normally do not include detailed urban parameterisation, such as for surface roughness or urban heat fluxes. Flow structure and dispersion of air pollutants within cities, however, are influenced by urban features such as increased surface roughness. This paper presents a study using MM5 and CMAQ to assess the effect of urban boundary layer features on meteorological parameters, and hence London's air quality. MM5 is a non-hydrostatic (version 3), terrain-following sigma-coordinate model designed to simulate mesoscale and regional-scale atmospheric circulation. This paper employs an improved surface roughness treatment on meteorological profiles and pollution dispersion. A surface roughness scale has been developed for London and the surrounding region. The land cover data was derived from the Centre for Ecology and Hydrology (CEH) data, with a spatial resolution of 25 × 25 m. These z_o values are employed with MM5 for modelling meteorological parameters over London, covering an inner domain area of 49 × 49 km. The outputs of MM5 have been coupled to CMAQ photochemical model to predict concentrations of particles, NO_2 and O_3 for London and the surrounding regions at a spatial resolution of 1 × 1 km. The predicted concentrations have been compared with monitored data obtained from a range of national air quality monitoring sites including Central London (Bloomsbury, Brent), East London (Bexley) and West London (Hillingdon). Comparison of hourly model predictions with measured data is made for pollution levels for

    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 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

    Objectives Basic life support (BLS) training in schools is associated with improved outcomes from cardiac arrest. International consensus statements have recommended universal BLS training for school-aged children. The current practice of BLS training in London schools is unknown. The aim of this study was to assess current practices of BLS training in London secondary schools. Setting, population and outcomes A prospective audit of BLS training in London secondary schools was conducted. Schools were contacted by email, and a subsequent telephone interview was conducted with staff familiar with local training practices. Response data were anonymised and captured electronically. Universal training was defined as any programme which delivers BLS training to all students in the school. Descriptive statistics were used to summarise the results. Results A total of 65 schools completed the survey covering an estimated student population of 65 396 across 19 of 32 London boroughs. There were 5 (8%) schools that provide universal training programmes for students and an additional 31 (48%) offering training as part of an extracurricular programme or chosen module. An automated external defibrillator (AED) was available in 18 (28%) schools, unavailable in 40 (61%) and 7 (11%) reported their AED provision as unknown. The most common reasons for not having a universal BLS training programme are the requirement for additional class time (28%) and that funding is unavailable for such a programme (28%). There were 5 students who died from sudden cardiac arrest over the period of the past 10 years. Conclusions BLS training rates in London secondary schools are low, and the majority of schools do not have an AED available in case of emergency. These data highlight an opportunity to improve BLS training and AEDs provision. Future studies should assess programmes which are cost-effective and do not require significant amounts of additional class time. PMID:28062467

    A large number of policy initiatives are being taken at the European level, across the United Kingdom and in London to improve air quality and reduce population exposure to harmful pollutants from traffic emissions. Trends in roadside increments of nitrogen oxides (NOX), nitrogen dioxide (NO2), particulate matter (PM), black carbon (CBLK) and carbon dioxide (CO2) were examined at 65 London monitoring sites for two periods of time: 2005-2009 and 2010-2014. Between 2005 and 2009 there was an overall increase in NO2 reflecting the growing evidence of real world emissions from diesel vehicles. Conversely, NO2 decreased by 10%·year(-1) from 2010 onwards along with PM2.5 (-28%·year(-1)) and black carbon (-11%·year(-1)). Downwards trends in air pollutants were not fully explained by changes in traffic counts therefore traffic exhaust emission abatement policies were proved to be successful in some locations. PM10 concentrations showed no significant overall change suggesting an increase in coarse particles which offset the decrease in tailpipe emissions; this was especially the case on roads in outer London where an increase in the number of Heavy Good Vehicles (HGVs) was seen. The majority of roads with increasing NOX experienced an increase in buses and coaches. Changes in CO2 from 2010 onwards did not match the downward predictions from reduced traffic flows and improved fleet efficiency. CO2 increased along with increasing HGVs and buses. Polices to manage air pollution provided differential benefits across London's road network. To investigate this, k-means clustering technique was applied to group roads which behaved similarly in terms of trends to evaluate the effectiveness of policies to mitigate traffic emissions. This is the first time that London's roadside monitoring sites have been considered as a population rather than summarized as a mean behaviour only, allowing greater insight into the differential changes in air pollution abatement policies.

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

    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.

    Measurements of NO2, ΣPNs, ΣANs and HNO3 have been done using a TD-LIF instrument, installed on board the FAAM BAe-146 research aircraft, during the RONOCO (ROle of Nighttime chemistry in controlling the Oxidising Capacity) campaign. We analyse in detail the chemical mechanisms that have been established during two flights (B536 and B548) characterized by a similar track (flying above the M25 highway around London) and carried out during a day (B548) and a night (B536). In the daytime flight, the chemical species around London present a net spatial distribution defining two distinct areas: the East London region (up-wind) with an older and less polluted (lowest concentrations of NOx) air masses and the West London region (down-wind) with fresh emissions and more polluted (highest concentrations of NOx with peaks of about 30 ppb). In correspondence of these peaks strong ozone tritation phenomena due to the high NOx levels are verified with a corresponding increase of the ΣANs concentrations. In order to verify the impact of the high concentrations of alkyl nitrate (with maximum values of about 3 ppb) on the tropospheric ozone budget, the production and loss of ozone and ΣANs has been studied. The slopes between the production of ozone and alkyl nitrates confirm that around London the ΣANs formation on one side and the relative ozone loss on the other side represent significant processes. Moreover, the loss of the O3 during the nocturnal flight (B536) is less evident that during the B548 flight.

    During archaeological investigation by Gifford of St Pancras Old Church burial ground, on the eastern edge of Somers Town, London, in advance of construction of the new London terminus for the Channel Tunnel Rail Link, a full porcelain denture was discovered. The high quality porcelain dentures, manufactured in the late eighteenth century French style, may have been brought with their owner, Archbishop Arthur Richard Dillon, on his journey into exile. There is evidence of prolonged use, not only for cosmetic or vocal functions but also in mastication. The dentures are unique archaeological artefacts and represent a pivotal time in dental history, with the adoption of new materials and methods of manufacture. They reflect a period of significant social and economic change for the upper echelons of French society. This paper outlines the development of porcelain dentures, discusses the prosthesis, their owner, and a possible provenance.

Migration flows into and out of the regions are used to examine the extent to which the regions were integrated into the British migration system, and the relative importance of rural to urban migration is assessed.... Analysis reveals a high degree of short-distance mobility within regions and emphasises the dominance of London in longer-distance migration.... It is also suggested that the role of towns in the migration system has previously been overemphasised, with much migration taking place between small settlements and some movement from large cities to smaller towns and villages.... The analysis challenges some accepted notions about migration in the past, and contributes to the debate about the extent to which British regions became part of a national economic and social system from the 18th century."

    This paper addresses how crimes of genocide go beyond a need for naked power, economic aggrandizement, or territorial conquest. Such crimes involve psychogenic and psychodynamic underpinnings that can be terrifying to contemplate. Yet their psychological study is essential. The Armenian genocide has been taken as a point of reference. Because the Armenian genocide has resulted in nearly a century-long effort of perpetrator denial, it can provide an important case study of how long-standing trauma and denial reinforce each other and illuminate each other. As a result, this genocide has aptly been called the "secret genocide," the "unremembered genocide," and a "crime without a name." The author holds that genocidal trauma (and trauma in general) is contagious and the contagion is likely to be insidious. All who come in contact with it can come away marked, including victim, victim families and progeny, observers, advocates, researchers, and yes, perpetrators.

    Background Cape Town has one of the highest TB burdens of any city in the world. In 1900 the City of Cape Town, New York City and London had high mortality of tuberculosis (TB). Throughout the 20th century contemporaneous public health measures including screening, diagnosis and treatment were implemented in all three settings. Mandatory notification of TB and vital status enabled comparison of disease burden trajectories. Methods TB mortality, notification and case fatality rates were calculated from 1912 to 2012 using annual TB notifications, TB death certifications and population estimates. Notification rates were stratified by age and in Cape Town by HIV status (from 2009 onwards). Results Pre-chemotherapy, TB mortality and notification rates declined steadily in New York and London but remained high in Cape Town. Following introduction of combination chemotherapy, mean annual case fatality dropped from 45–60% to below 10% in all three settings. Mortality and notification rates subsequently declined, although Cape Town notifications did not decline as far as those in New York or London and returned to pre-chemotherapy levels by 1980. The proportional contribution of childhood TB diminished in New York and London but remained high in Cape Town. The advent of the Cape Town HIV-epidemic in the 1990s was associated with a further two-fold increase in incidence. In 2012, notification rates among HIV-negatives remained at pre-chemotherapy levels. Conclusions TB control was achieved in New York and London but failed in Cape Town. The TB disease burden trajectories started diverging before the availability of combination chemotherapy in 1952 and further diverged following the HIV epidemic in 1990. Chemotherapy impacted case fatality but not transmission, evidenced by on-going high childhood TB rates. Currently endemic TB results from high on-going transmission, which has been exacerbated by the HIV epidemic. TB control will require reducing transmission, which is

    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(As(1-x)P(x))2 [K. Hashimoto et al., Science 336, 1554 (2012)].

    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.

    2002-07-01

    For multicomponent superconductors, it is known that the presence of symmetry breaking fields can lead to multiple superconducting phase transitions. Motivated by recent small angle neutron scattering experiments on the vortex state of UPt3, the London theory in the vicinity of such phase transitions is determined. It is found that the form of this London theory is in general quite different than that for conventional superconductors. This is due to the existence of a diverging correlation length associated with these phase transitions. One striking consequence is that nontrivial vortex lattices exist arbitrarily close to H(c1). Applications to UPt3, CeIn3, U(1-x)Th(x)Be(13), electron doped cuprate superconductors, Sr(2)RuO(4), and MgCNi(3) are discussed.

  5. Response of London's urban heat island to a marine air intrusion in an easterly wind regime

    2010-09-01

    London is long known to develop a pronounced urban heat island (UHI) resulting primarily from the storage of heat in the urban fabric during the day and released during the night, the differences in thermal and radiative properties of the surface between urban and rural areas, and lack of evapotranspiration in urban areas. Under calm, clear, and dry weather conditions, the difference in near-surface air temperature between two representative urban centre and rural locations at a given time typically reaches several degrees (i.e. warming) during the night and can be negative (i.e. cooling) during the day. Like the majority of large cities in the world, London is located in a coastal area. On certain occasions cooler marine air from the North Sea is advected across London by a sea breeze or easterly winds. In our work we examine the effects of a marine air intrusion, in an easterly wind regime, on the structure of London's UHI for a case study on 7 May 2008. For this purpose, numerical simulations with the Weather Research and Forecast (WRF) model are performed for multiple nested domains with the innermost domain covering London and its rural surroundings at the kilometre scale. A sensitivity study is undertaken to assess how the categorisation of the urban land use and the parameterisation of the urban canopy in the model affect its performance characteristics for the near-surface air temperature field. The categorisation of the urban landuse, according to the fractional area that is built-up within each grid cell, is found to be key to capturing the spatial pattern of the temperature field. Using a multilayer rather than single layer urban canopy model improves the representation of the variability of the pattern and the intensity of the UHI. A notable outcome of this work is that the inclusion of building anthropogenic fluxes is comparatively less important as regards model performance for near-surface air temperature. The effects of the marine air intrusion on

    The Atlas of Cancer Mortality for England and Wales showed pronounced excesses of male mortality from nasal and bladder cancer in certain London boroughs. These excesses were investigated by case-referent studies using death certificate data for male deaths, 1968-78. Nasal cancer was found to be significantly associated with occupations involving heavy exposure to wood dust. Bladder cancer was significantly associated with occupations in road transport driving and in the handling of leather, whereas consistently raised relative risk ratios were also found for wood-workers, engineering fitters, printers, machinists, plumbers, and motor mechanics. These findings highlight the potential role of occupational factors in cancer causation in London. Images PMID:3947560

    We extend the Ginsburg-Landau solution for cutoff function in London equation to low temperatures by solving numerically the quasiclassical Eilenberger equations in mixed state of s -wave superconductors. As a result the nonlocal generalized London equation (NGLE) is obtained. The magnetic field and temperature dependence of the cutoff function parameter k1(B,T) are calculated. Due to Kramer-Pesch effect k1 decreases strongly at low temperatures. It is also found that k1 has a minimum at a value of magnetic field depending on temperature. We reduce the NGLE model to an effective local model and calculate the value of an effective penetration depth λeff(B,T) . The sublinear field dependence of λeff is predicted that agrees with experimental μ SR results for the penetration depth of magnetic field in the s -wave superconductor V3Si and NbSe2 .

    This study evaluated the effects of socio-economic variables and migration history on the prevalence of betel nut and smokeless tobacco use in both UK- and Bangladeshi born migrant women resident in London. No significant difference in betel nut use prevalence was found among women of different generations. However, in all groups betel nut users were significantly older and less educated than non-users. Among first generation women there was no effect of either length of time living in the UK or age at migration on use of betel nut, even after controlling for current age. No significant differences in prevalence use due to language spoken, occupation, marital status or borough of residence in London were found. We conclude that, although there are some indications of a change in behavior among younger individuals, betel nut chewing is a practice very much present among Bangladeshi women born and brought up in a bicultural context.

  10. Bipartisan politics and practical knowledge: advertising of public science in two London newspapers, 1695-1720.

    PubMed

    Wigelsworth, Jeffrey R

    2008-12-01

    This article explores the enticement of consumers for natural philosophy (buyers of books, audiences at public lectures and purchasers of instruments) in London between 1695 and 1720 through advertisements placed in two political newspapers. This twenty-five-year period witnessed both the birth of public science and the rage of party politics. A consideration of public science adverts within the Whig-leaning Post Man and the Tory-leaning Post Boy reveals that members of both the Whig and Tory parties were equally targeted and that natural philosophy was sold to London's reading population in bipartisan fashion. In the process of integrating natural philosophy into the wider culture through commercial sales, political allegiances were not imprinted on the advertising process. This conclusion raises questions regarding the historiographical assertion of Whig-supported public science and Tory opposition to it at the level of consumers.

  11. Modelling lead bioaccessibility in urban topsoils based on data from Glasgow, London, Northampton and Swansea, UK.

    Predictive linear regression (LR) modelling between bioaccessible Pb and a range of total elemental compositions and soil properties was executed for the Glasgow, London, Northampton and Swansea urban areas in order to assess the potential for developing a national urban bioaccessible Pb dataset for the UK. LR indicates that total Pb is the only highly significant independent variable for estimating the bioaccessibility of Pb. Bootstrap resampling shows that the relationship between total Pb and bioaccessible Pb is broadly the same in the four urban areas. The median bioaccessible fraction ranges from 38% in Northampton to 68% in London and Swansea. Results of this study can be used as part of a lines of evidence approach to localised risk assessment but should not be used to replace bioaccessibility testing at individual sites where local conditions may vary considerably from the broad overview presented in this study.

  12. The Rise of Massage and Medical Gymnastics in London and Paris before the First World War.

    2017-01-01

    Massage and medical gymnastics experienced a rapid institutionalization across Europe and North America between 1850 and 1914. This article explores how this process took place in London and Paris. Physiotherapy developed many of the hallmarks of an independent discipline during this period, including an identified corpus of manipulations and exercises, some autonomous training courses and degrees for future practitioners, and even the creation of departments within several hospitals. The article analyzes all of the processes surrounding this rise, paying special attention to the influence of the ambassadors of Swedish gymnastics (which led to the re-invention of massage across Europe), to the installation of physiotherapy in hospitals in London and in Paris, and to the practical and institutional innovations driven by nurses in England and by doctors in France.

    Tobacco kills 5 million people annually. By the mid 2020s, that figure will increase to about 10 million a year, with most of the deaths occurring in developing countries. This review explains how early technological and regulatory developments contributed to the epidemic, reveals the efforts of the tobacco industry to conceal its products' harmfulness, and stresses the role of the globalization of trade and marketing as a means of increasing consumption world-wide. The results of tens of thousands of studies published globally over the past 50 years point to an association between smoking and lung cancer and other adverse health effects, and the non-smoker's rights movement has exposed the wide-spread perils of 'secondhand' smoke. Yet, the tobacco industry continues its global expansion, and consumers in low- and middle-income countries are especially susceptible to its marketing tactics. This review ends by emphasising the need for a global public-health response, and identifies the Framework Convention on Tobacco Control as a significant effort. It stresses the need for accelerated action and innovative tobacco-control efforts, if the projected death toll is to be reduced in this century.

  16. Wastewater filtration and re-use: an alternative water source for London.

    PubMed

    2012-10-15

    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

    SO(2) is no longer the principal factor influencing the vitality and composition of lichen assemblages in London. We provide direct evidence for an impact on lichen growth during episodic high exhaust emissions coupled with unusual climatic conditions. This suggests a combination of particles and nitrogen plays a major role in influencing lichen growth. Nitrogen from traffic emissions may be at least as important as agriculture in influencing the composition of lichen assemblages.

    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.

    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

    2011-01-01

    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

    Objectives We compared 2 sociocultural cohorts with different duration of exposure to graphic health warning labels (GHWL), to investigate a possible desensitisation to their use. We further studied how a differing awareness and emotional impact of smoking-associated risks could be used to prevent this. Setting Structured interviews of patients from the general respiratory department were undertaken between 2012 and 2013 in 2 tertiary hospitals in Singapore and London. Participants 266 participants were studied, 163 Londoners (35% smokers, 54% male, age 52±18 years) and 103 Singaporeans (53% smokers, p=0.003; 78% male, p<0.001; age 58±15 years, p=0.012). Main outcomes and measures 50 items assessed demographics, smoking history, knowledge and the deterring impact of smoking-associated risks. After showing 10 GHWL, the impact on emotional response, cognitive processing and intended smoking behaviour was recorded. Results Singaporeans scored lower than the Londoners across all label processing constructs, and this was consistent for the smoking and non-smoking groups. Londoners experienced more ‘disgust’ and felt GHWL were more effective at preventing initiation of, or quitting, smoking. Singaporeans had a lower awareness of lung cancer (82% vs 96%, p<0.001), despite ranking it as the most deterring consequence of smoking. Overall, ‘blindness’ was the least known potential risk (28%), despite being ranked as more deterring than ‘stroke’ and ‘oral cancer’ in all participants. Conclusions The length of exposure to GHWL impacts on the effectiveness. However, acknowledging the different levels of awareness and emotional impact of smoking-associated risks within different sociocultural cohorts could be used to maintain their impact. PMID:27798017

    Chronological age estimation from the dental parameters is becoming increasingly important. The London atlas of tooth development is the most recent developed method and represents a modification of the previous older methods. The aim of this study was to evaluate the accuracy of the London atlas for the dental age estimation in the Portuguese population. The study sample included 736 radiographic images (498 females and 238 males) of Portuguese origin, patients of Dental Clinic of Superior Institute of Health Sciences Egas Moniz and Dental Medicine Faculty, University of Lisbon. The age range of the individuals was between 3 and 24 years. Estimated age was compared with the chronological age using the paired t-test. The results showed that there was no statistically significant difference between left and right side of the jaw (p>0.05). Both sides showed an average overestimation of age by one month approximately. Moreover, the significant difference between chronological and estimated age was not observed in the females. However, the significant difference was observed in a sample coming from males (right: p=0.008; left: p=0.003). Our results showed that the London atlas can be potentially used as a tool for age estimation. However, the difference between sexes clearly suggests that separate charts should be made for each sex. Further studies, which will have as a final goal the development of a new method for age estimation using dental parameters, are needed.

    2013-10-10

    Terahertz spectroscopy provides direct information concerning weak intermolecular forces in crystalline molecular solids and therefore acts as an excellent method for calibrating and evaluating computational models for noncovalent interactions. In this study, the low-frequency vibrations of two dipeptides were compared, acyclic diglycine and cyclic diglycine, as benchmark systems for gauging the performance of semiempirical London force correction approaches. The diglycine samples were investigated using pulsed terahertz spectroscopy from 10 to 100 cm(-1) and then analyzed using solid-state density functional theory (DFT) augmented with existing London force corrections, as well as a new parametrization (DFT-DX) based on known experimental values. The two diglycine molecules provide a useful test for the applied models given their similarities, but more importantly the differences in the intermolecular forces displayed by each. It was found that all of the considered London force correction models were able to generate diglycine crystal structures of similar accuracy, but considerable variation occurred in their abilities to predict terahertz frequency vibrations. The DFT-DX parametrization was particularly successful in this investigation and shows promise for the improved analysis of low-frequency spectra.

    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

    Ophelia in Shakespeare's Hamlet is named for the ``moist star" which in mythology is the partner of Hamlet's royal Sun. Together the couple seem destined to rule on earth just as their celestial counterparts rule the heavens, but the tragedy is that they are afflicted, just as the Sun and Moon are blemished. In 1.3 Laertes lectures Ophelia on love and chastity, describing first Cytherean phases (crescent to gibbous) and then Lunar craters. Spots mar the Sun (1.1, 3.1). Also reported are Jupiter's Red Spot (3.4) and the resolution of the Milky Way into stars (2.2). These interpretations are well-founded and support the cosmic allegory. Observations must have been made with optical aid, probably the perspective glass of Leonard Digges, father of Thomas Digges. Notably absent from Hamlet is mention of the Galilean moons, owing perhaps to the narrow field-of-view of the telescope. That discovery is later celebrated in Cymbeline, published soon after Galileo's Siderius Nuncius in 1610. In 5.4 of Cymbeline the four ghosts dance ``in imitation of planetary motions" and at Jupiter's behest place a book on the chest of Posthumus Leonatus. His name identifies the Digges father and son as the source of data in Hamlet since Jupiter's moons were discovered after the deaths of Leonard (``leon+hart") and Thomas (the ``lion's whelp"). Lines in 5.4 urge us not to read more into the book than is contained between its covers; this is understandable because Hamlet had already reported the other data in support of heliocentricism and the cosmic model discussed and depicted by Thomas Digges in 1576. I conclude therefore that astronomical telescopy began in England before the last quarter of the sixteenth century.

    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

    An historic 20-in (50.8-cm) Grubb reflector originally owned by the London amateur astronomer, Henry Ellis, was transferred to Australia in 1928. After passing through a number of amateur owners the Catts Telescope - as it became known locally - was acquired by Mount Stromlo Observatory in 1952, and was then used for astrophysical research and for site-testing. In the mid-1960s the telescope was transferred to the University of Western Australia and was installed at Perth Observatory, but with other demands on the use of the dome it was removed in 1999 and placed in storage, thus ending a century of service to astronomy in England and Australia.

    An old topographic compass displayed in a showroom of the Museu de Astronomia e Ciências Afins (MAST), in Rio de Janeiro, Brazil, took our curiosity namely because of its resemblance to a theodolite, described by J.H. de Magellan. Not many things were known about its previous history. From the different documents studied, and the characteristics of this singular theodolite, it must have belonged to the collections of instruments acquired for the Brazilian border demarcations undertaken after the Santo Ildefonso Treaty, agreed to by the Portuguese and Spanish courts in 1777. Several instruments were bought in London, and supervised and chosen by Magellan, the Portuguese instruments expert. We present arguments in favour of this conclusion.

    Direct measurements of NOx concentration and flux were made from a tall tower in central London, UK as part of the Clean Air for London (ClearfLo) project. Fast time resolution (10 Hz) NO and NO2 concentrations were measured and combined with fast vertical wind measurements to provide top-down flux estimates using the eddy covariance technique. Measured NOx fluxes were usually positive and ranged from close to zero at night to 2000-8000 ng m(-2) s(-1) during the day. Peak fluxes were usually observed in the morning, coincident with the maximum traffic flow. Measurements of the NOx flux have been scaled and compared to the UK National Atmospheric Emissions Inventory (NAEI) estimate of NOx emission for the measurement footprint. The measurements are on average 80% higher than the NAEI emission inventory for all of London. Observations made in westerly airflow (from parts of London where traffic is a smaller fraction of the NOx source) showed a better agreement on average with the inventory. The observations suggest that the emissions inventory is poorest at estimating NOx when traffic is the dominant source, in this case from an easterly direction from the BT Tower. Agreement between the measurements and the London Atmospheric Emissions Inventory (LAEI) are better, due to the more explicit treatment of traffic flow by this more detailed inventory. The flux observations support previous tailpipe observations of higher NOx emitted from the London vehicle diesel fleet than is represented in the NAEI or predicted for several EURO emission control technologies. Higher-than-anticipated vehicle NOx is likely responsible for the significant discrepancies that exist in London between observed NOx and long-term NOx projections.

    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

  17. Making Bengali Brick Lane: claiming and contesting space in East London.

    Alexander, Claire

    2011-06-01

    Based on a recent empirical project on 'the Bengal diaspora', the paper explores the construction and contestation of meanings around the iconic East London street, Brick Lane. Taking the 2006 protests around the film Brick Lane as its starting point, the paper draws on original interviews conducted in 2008 with a range of Bengali community representatives, to examine the narratives of space, community and belonging that emerge around the idea of Brick Lane as the 'cultural heartland' of the British Bangladeshi community. By exploring the representation, production and contestation of 'social space' through everyday practices, the paper engages with and contests the representation of minority ethnic 'communities' in the context of contemporary multicultural London and examines the process of 'claiming' and 'making' space in East London. In so doing, the paper contributes to a critical tradition that challenges essentialising and pathologizing accounts of ethnic communities and racialized spaces, or that places them outside of broader social and historical processes - redolent, for example, in contemporary discussions about 'parallel lives' or 'the clash of civilizations'. By contrast, this paper views social space as made through movement and narration, with a particular emphasis on the social agency of local Bengali inhabitants and the multiple meanings that emerge from within this 'imagined community'. However, rather than simply stressing the unfinished and processual nature of spatial meanings, the paper insists on the historical, embodied and affective dimensions of such meaning making, and a reckoning with the broader social and political landscape within which such meanings take shape. The focus on Brick Lane provides an empirically rich, geographically and historically located lens through which to explore the complex role of ethnicity as a marker of social space and of spatial practices of resistance and identity.

    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.

  19. Analysis of the cost of hydrogen infrastructure for buses in London

    NASA Astrophysics Data System (ADS)

    Shayegan, S.; Hart, D.; Pearson, P.; Joffe, D.

    The use of hydrogen (H 2) as transport fuel is often said to suffer from the 'chicken and egg' problem: vehicles that depend on H 2 cannot go on the roads due to the lack of an adequate infrastructure, and the almost non-existent fleet of H 2 vehicles on the roads makes it economically unsound to build a H 2 infrastructure. Although both hydrogen vehicles (fuel cell and internal combustion engine) and the related infrastructure have been (and are being) developed and some are commercially available, cost is seen as a major barrier. With today's technologies, H 2 only becomes competitive with petrol and diesel when produced at large quantities, suitable for supplying e.g. thousands of H 2 buses. The question is, how might this point be reached, and are there least cost infrastructural pathways to reach it. This paper tries to address the latter question, using the early development of a H 2 infrastructure for buses in London as a case study. The paper presents some of the analyses and results from a Ph.D. project (in progress) being undertaken at Imperial College London, funded by EPSRC (Grant GR/R50790/01). The results presented here illustrate that cost of hydrogen production and delivery vary mainly with levels of hydrogen demand and delivery distances, as well as other logistic criteria; least cost production-delivery pathways have been identified for various hydrogen demand scenarios and refuelling station set-ups. Another important conclusion is that the pattern of converting a group of refuelling stations to hydrogen (e.g. a group of refuelling stations for buses in London) has a significant effect on the unit cost of hydrogen.

    OBJECTIVE--To assess the effect of the London helicopter emergency medical service on survival after trauma. DESIGN--Prospective comparison of outcomes in cohorts of seriously injured patients attended by the helicopter and attended by London ambulance service land ambulances crewed by paramedics. SETTING--Greater London. SUBJECTS--337 patients attended by helicopter and 466 patients attended by ambulance who sustained traumatic injuries and died, stayed in hospital three or more nights, or had other evidence of severe injury and who were taken to any one of 20 primary receiving hospitals. MAIN OUTCOME MEASURE--Survival at six months after the incident. RESULTS--After differences in the nature and severity of the injuries in the two cohorts were accounted for the estimated survival rates were the same (relative risk of death with helicopter = 1.0; 95% confidence interval 0.7 to 1.4). An analysis with trauma and injury severity scores (TRISS) found 16% more deaths than predicted in the helicopter cohort but only 2% more in the ambulance cohort. There was no evidence of a difference in survival for patients with head injury but a little evidence that patients with major trauma (injury severity score > or = 16) were more likely to survive if attended by the helicopter. An estimated 13 (-5 to 39) extra patients with major trauma could survive each year if attended by the helicopter. CONCLUSION--Any benefit in survival is restricted to patients with very severe injuries and amounts to an estimated one additional survivor of major trauma each month. Over all the helicopter caseload, however, there is no evidence that it improves the chance of survival in trauma. PMID:7627033

    In this study, we investigate the spatial distribution of PM1 in the greater London area during the Clean Air for London (ClearfLo) project in winter 2012 by applying two High-Resolution Time-of-Flight Aerosol Mass Spectrometers (HR-ToF-AMS) at a rural site (Detling, Kent) and an urban site (North Kensington, London). While the concentration of organic aerosol (OA) is comparable between the rural and urban sites, the OA sources are distinctly different. Due to elevated domestic heating in the urban area, the concentration of solid fuel OA at the urban site is about twice as high as at the rural site. In contrast, the OOA concentration at the rural site is almost twice that of the urban site. This is likely caused by a steep concentration gradient of OOA when air masses are advected from polluted mainland Europe. Taking advantage of low biogenic emissions in winter, the sources of OOA, which are highly uncertain, are investigated. Combing Positive Matrix Factorization (PMF) analysis and radiocarbon analysis, the majority of OOA is estimated to arise from aged biomass burning. We deploy a suite of instruments to investigate the organic volatility at the rural Detling site. After heating at 250°C in a thermal-denuder (TD), the mass fraction remaining of organics is 16%, which indicates the presence of non-volatile organics. By comparing the OA associated with refractory black carbon (measured by a soot-particle aerosol mass spectrometer) and total OA (measured by a HR-ToF-AMS), we proposed that the non-volatile organics have similar sources or have undergone similar chemical processing as refractory black carbon in the atmosphere. Finally, we will discuss the relationship between the volatility and the degree of oxidation of organics.

    Concentrations and fluxes of seven volatile organic compounds (VOCs) were measured between August and December 2012 at a rooftop site in central London as part of the ClearfLo project (Clean Air for London). VOC concentrations were quantified using a proton transfer reaction mass spectrometer (PTR-MS) and fluxes were calculated using a virtual disjunct eddy covariance technique. The median VOC fluxes, including aromatics, oxygenated compounds and isoprene, ranged from 0.07 to 0.33 mg m-2 h-1. Median mixing ratios were 7.3 ppb for methanol and < 1 ppb for the other compounds. Strong relationships were observed between the fluxes and concentrations of some VOCs with traffic density and between the fluxes and concentrations of isoprene and oxygenated compounds with photosynthetically active radiation (PAR) and temperature. An estimated 50-90 % of the fluxes of aromatic VOCs were attributable to traffic activity, which showed little seasonal variation, suggesting that boundary layer effects or possibly advected pollution may be the primary causes of increased concentrations of aromatics in winter. Isoprene, methanol and acetaldehyde fluxes and concentrations in August and September showed high correlations with PAR and temperature, when fluxes and concentrations were largest suggesting that biogenic sources contributed to their fluxes. Modelled biogenic isoprene fluxes from urban vegetation using the Guenther et al. (1995) algorithm agreed well with measured fluxes in August and September. Comparisons of estimated annual benzene emissions from both the London and the National Atmospheric Emissions Inventories agreed well with measured benzene fluxes. Flux footprint analysis indicated emission sources were localised and that boundary layer dynamics and source strengths were responsible for temporal and spatial VOC flux and concentration variability during the measurement period.

VOC concentrations were quantified using a proton transfer reaction-mass spectrometer and fluxes were calculated using a virtual disjunct eddy covariance technique. The median VOC fluxes, including aromatics, oxygenated compounds and isoprene, ranged from 0.07 to 0.33 mg m-2 h-1 and mixing ratios were 7.27 ppb for methanol (m / z 33) and <1 ppb for the remaining compounds. Strong relationships were observed between most VOC fluxes and concentrations with traffic density, but also with photosynthetically active radiation (PAR) and temperature for the oxygenated compounds and isoprene. An estimated 50-90 % of aromatic fluxes were attributable to traffic activity, which showed little seasonal variation, suggesting boundary layer effects or possibly advected pollution may be the primary causes of increased concentrations of aromatics in winter. PAR and temperature-dependent processes accounted for the majority of isoprene, methanol and acetaldehyde fluxes and concentrations in August and September, when fluxes and concentrations were largest. Modelled biogenic isoprene fluxes using the G95 algorithm agreed well with measured fluxes in August and September, due to urban vegetation. Comparisons of estimated annual benzene emissions from the London and National Atmospheric Emissions Inventory agreed well with measured benzene fluxes. Flux footprint analysis indicated emission sources were localized and that boundary layer dynamics and source strengths were responsible for temporal and spatial VOC flux and concentration variability during the measurement period.

  4. Exploiting London dispersion forces in nonequilibrium growth of surface-based nanostructures

    Zhang, Zhenyu

    2013-03-01

    London dispersion forcedescribes the weak interaction between transient dipoles or multipoles associated with different parts of matter, and accounts for a major part of the attractive van der Waals (vdW) force. It is ubiquitous in nature, yet its importance in various physical and chemical processes just starts to be increasingly recognized. Such advances through definitive quantitative studies are largely enabled by the availability of more accurate descriptions of the weak interactions associated with long-range electron correlation effects within first-principles approaches. The present talk contains two parts, both obtained within the vdW-DF scheme on the theory side. In the first part, we critically assess the binding strengths of different classes of adatoms on ultrathin metal films of varying thicknesses. For inert gas atoms such as Xe, the London dispersion force is found to drastically enhance their adsorption, but the overall binding behavior depends only weakly on the film thickness. In contrast, for atoms with unpaired valence electrons such as H or O, the overall binding is much stronger, and also depends more sensitively on the film thickness, but with a much weaker and (in some cases) repulsive vdW contribution. These results have important implications in our developing a better understanding of atomic and molecular adsorption on different metal substrates. In the second part, 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 multi-scale modeling integrating first-principles calculations with kinetic rate equation analysis shows that a drastic reduction in the growth temperature, from 1000°C to (250-300)°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 enhanced London dispersion forces effectively prevent easy desorption of the

    Background The control of tuberculosis (TB) is founded on early case detection and complete treatment of disease. In the UK, TB is concentrated in subgroups of the population in large urban centres. The impact of homelessness, imprisonment and problem drug use on TB control in London is reviewed. Methods A cohort study was undertaken of all patients with TB in Greater London to determine the point prevalence of disease in different groups and to examine risk factors for smear positivity, drug resistance, treatment adherence, loss to follow‐up and use of directly observed therapy (DOT). Results Data were collected on 97% (1941/1995) of eligible patients. The overall prevalence of TB was 27 per 100 000. An extremely high prevalence of TB was seen in homeless people (788/100 000), problem drug users (354/100 000) and prisoners (208/100 000). Multivariate analysis showed that problem drug use was associated with smear positive disease (OR 2.2, p<0.001), being part of a known outbreak of drug resistant TB (OR 3.5, p = 0.001) and loss to follow‐up (OR 2.7, p<0.001). Imprisonment was associated with being part of the outbreak (OR 10.3, p<0.001) and poor adherence (OR 3.9, p<0.001). Homelessness was associated with infectious TB (OR 1.6, p = 0.05), multidrug resistance (OR 2.1, p = 0.03), poor adherence (OR 2.5, p<0.001) and loss to follow‐up (OR 3.8, p<0.001). In London, homeless people, prisoners and problem drug users collectively comprise 17% of TB cases, 44% of smear positive drug resistant cases, 38% of poorly compliant cases and 44% of cases lost to follow‐up. 15% of these patients start treatment on DOT but 46% end up on DOT. Conclusions High levels of infectious and drug resistant disease, poor adherence and loss to follow‐up care indicate that TB is not effectively controlled among homeless people, prisoners and problem drug users in London.

    Several studies have pointed adverse effects of long term migration on eating habits. Research is needed to understand if this effect occurs also with a short length of migration, as is the case of international students. Our aim was to evaluate the effect of short and long term migration on eating habits of Portuguese university students. Participants were 46 English and 55 Portuguese students from universities in London, United Kingdom. The findings from this study highlight the difficulties that Portuguese students faced in maintaining a traditional Mediterranean diet after moving to a Northern European environment.

    A theoretical procedure to determine the heat transfer characteristics of the interline region (junction of liquid-solid-vapor) from the macroscopic optical and thermophysical properties of the system is outlined. The analysis is based on the premise that the interline transport processes are controlled by the London-van der Waals dispersion force between condensed phases (solid and liquid). Numerical values of the dispersion constant are presented. The procedure is used to compare the relative size of the interline heat sink of various systems using a constant heat flux mode. This solution demonstrates the importance of the interline heat flow number, which is evaluated for various systems.

    2012-12-01

    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. 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 a useful complementary pure water source for such a densely populated area. First, we define two localities where such a pumping scheme might operate; regions of thick unsaturated zone and high chalk transmissivity are 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. 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 southern coast similar to that beneath London, we are able to quantify the 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 fracture tips. Finally we inject an analogue `effluent' through a chalk core in the laboratory and perform ICP-AES analysis on the recovered solution, showing contaminant (viz. a suite of heavy metals) retardation or removal over relatively short time- and length-scales. Numerical and analytical solutions fit the data poorly, shedding some light on the importance of hydrodynamic dispersion on aqueous contaminants within chalk. We have been encouraged by (i) the success of other similar schemes worldwide in places as far apart (both physically and economically) as

    Both scientific and popular discourses assume that the environment can exert an influence on human health. Drawing on anthropological research conducted alongside mental health activists in the United Kingdom, I discuss how people affected by mental health problems sought to recover by visiting outdoor places in the London Borough of Richmond. Their intentional movement and stillness in the world involved tuning and narrative orientation, which, over time, became skilled. Recovery from mental ill-health was not an outcome of merely being in a particular place, but rather emerged as an ongoing process of relearning how to live in and as part of the environment.

    London Volcano is a major public engagement and outreach effort that emerged from a large-scale interdisciplinary research project on Strengthening Resilience in Volcanic Areas (STREVA). The activity was created for a 5-day public exhibition in London, in 2014, and brought together 3 elements to illustrate the timeline of a volcanic crisis: a 5m x 3m scale model of Soufrière St Vincent, an interactive 'monitoring station' to explore technology used in monitoring and an engaging 'bin bang' sequence to simulate a volcanic explosion. Having a large hands-on volcano as a centrepiece to the exhibit enabled interaction with primary-age school children through the use of creativity and imagination. They looked at seismic traces of 'bin bang' explosions; measured dispersal of projectile ducks; and decided where to place a model house on the island, on which the model volcano sat. Over the 5-days we evolved the activity of the volcano to re-create the 1902 eruption. During the first 3 days, 94 houses were placed around the volcano, but after the cataclysmic eruption mid-week, 12 of these houses were destroyed by simulated pyroclastic flows and lahars down the flanks of the volcano model. Light and sound were key parts of the London Volcano simulation. A sound track was created to mimic the sounds reported by eyewitnesses. Between eruptions, the volcano would intermittently rumble, adding excitement and unpredictability to the eruptions. Explosions were simulated with compressed-CO2 jets, and a G-flame; but these events were rare. Creative arts are an effective mechanism for transfer of knowledge from communities living with volcanic activity, so artwork from school children living near Tungurahua, Ecuador and poems from school children on Montserrat were on display. The London Volcano was a unique opportunity to engage with over 2,000 people on volcanic risk and what it means to live near a volcano.

    One hundred patients who were injured by London underground trains during 1981-6 were studied; 43 of them died. Deliberate self harm was probable in roughly three quarters. Alcohol intoxication was thought to play an important part in a further tenth of cases. Thirteen were psychiatric inpatients at the time of the incident, and a further two had recently been discharged. Early warning of a potential suicide attempt was given during the 24 hours preceding the incident in 15 of the cases. Some of the deaths in the psychiatric patients may have been preventable.

    The understanding of experienced pain has recently moved from the biological to the metaphorical. Detailed interviews with twelve Turkish and Kurdish patients in London who had been unsuccessfully investigated medically for chronic pain showed that their understanding reflected local, typically humoural, conceptions of self and body. However there was little to suggest interpretation of the illness as a more specific and grounded idiom for social or political experience. It is suggested that the current vogue for 'interpretation' in medical anthropology and social psychiatry may occasionally be, as Umberto Eco puts it, 'over-interpretation'.

    In the twentieth century, vaccination has been possibly the greatest revolution in health. Together with hygiene and antibiotics, vaccination led to the elimination of many childhood infectious diseases and contributed to the increase in disability-free life expectancy that in Western societies rose from 50 to 78-85 years (Crimmins, E.

In the twenty-first century, vaccination will be expected to eliminate the remaining childhood infectious diseases, such as meningococcal meningitis, respiratory syncytial virus, group A streptococcus, and will address the health challenges of this century such as those associated with ageing, antibiotic resistance, emerging infectious diseases and poverty. However, for this to happen, we need to increase the public trust in vaccination so that vaccines can be perceived as the best insurance against most diseases across all ages.

    In order to interpret composition measurements taken in London during the ClearfLo (Clean Air for London) campaign from 2011 to the present (with intensive measurement campaigns in summer and winter 2012), atmospheric dispersion modelling with the NAME model was undertaken. Measurements of a variety of trace gases, aerosols and meteorology were taken at five sites to the west of London, in central London and east of the city. Dispersion modelling showed when each site received the same air masses and whether the evolution of the air mass composition could be tracked as the air crossed the city. Variability in the level of pollutants and trace gases could be assigned to changes in air mass origin at certain times but more local events were too small scale to be assigned with this dispersion model. Dispersion modelling and using the resulting air mass footprints was found to be a useful visualisation as well as quantitative tool to interpret the many trace gas measurements at strategically different geographical locations around a city and help explain the complex air quality influences on London and the South east of England.

    Cholera is an acute infectious disease with high mortality if left untreated. Historically, between the 19th and 20th centuries seven great pandemics of cholera occurred and worldwide, thousands of people died. Based on an old theory, cholera was considered an air-born disease and the emergence of its outbreaks were attributed to bad weather or miasma. However later in the 18th century, British physician John Snow (1813-1858) explained the association of a terrible cholera outbreak in London in 1849 to contamination of the drinking water supply with human excreta. Despite his finding, the causative agent of this dreaded illness was unidentified until later in the 19th century. In 1854, Filippo Pacini (1812-1883) an anatomist from Italy and then in 1883, Robert Koch (1843-1910) the German bacteriologist, discovered ‘vibrio cholerae’ as the etiologic agent. During the major pandemics of cholera in 19th and 20th centuries this illness reached Iran and led to vast depopulation and a crucial impact on the country’s socioeconomic status. Poor public health conditions, lack of a well-organized public health authority for implementing preventive and quarantine measures as well as Iran’s specific geographic location were the main facilitating factors of the emergence of various epidemics, including cholera in Iran. The present paper briefly reviews the cholera outbreaks in Iran during the 19th and 20th centuries. PMID:25197514

  19. Ars scientia mores: science comes to English dentistry in the seventeenth century. 1. Medical publications and the Royal Society.

    During the late seventeenth century scientific knowledge came dentistry, much of it through the activity of the new Royal Society, which was initiated by gatherings in London and Oxford from 1645 and formally established in 1660 after the restoration of the monarchy. The Society received its first charter from Charles II in 1662 and from 1665 onwards published its Philosophical Transactions. This paper outlines items published in that journal, and other relevant scientific publications of the century, applicable to dentistry. A companion paper employs Allen's dental treatise, The operator for the teeth, first published in York in 1685 to provide the evidence that he was aware of several of these scientific findings of his day.

    Objective To shed light on experiences of patients with cancer in London National Health Service (NHS) trusts that may not be fully captured in national survey data, to inform improvement action plans by these trusts. Design Framework analysis of free-text data from 2012/2013 National Cancer Patient Experience Survey (NCPES) from the 2 London Integrated Cancer Systems. Setting and participants Patients with a cancer diagnosis treated by the NHS across 27 trusts in London. Main outcome measures Free-text data received from patients categorised into what patients found good about their cancer care and what could be improved. Methods Using Framework analysis, a thematic framework was created for 15 403 comments from over 6500 patients. Themes were identified across the London data set, by tumour group and by trust. Results Two-thirds of free-text comments from patients in London were positive and one-third of those related to the good quality of care those patients received. However, the majority of comments for improvement related to quality of care, with a focus on poor care, poor communication and waiting times in outpatient departments. Additionally, 577 patients (9% of those who returned free-text data in London) commented on issues pertaining to the questionnaire itself. Some patients who experienced care from multiple trusts were unclear on how to complete the questionnaire for the single trust whose care they were asked to comment on, others said the questions did not fit their experiences. Conclusions NCPES free-text analysis can shed light on the experiences of patients that closed questions might not reveal. It further indicates that there are issues with the survey itself, in terms of ambiguities in the questionnaire and difficulties in identifying patients within specific trusts. Both of these issues have the potential to contribute to knowledge and understanding of the uses and limitations of free-text data in improving cancer services. PMID:26482767

  1. Numerical Simulations of Daytime Temperature and Humidity Crossover Effects in London

    Sparks, N.; Toumi, R.

    2015-01-01

    The effect of the London urban area on vertical profiles of temperature and humidity was analyzed using a mesoscale model. It was found that the near-surface warming and drying effects usually associated with the urban heat island in London in the summer daytime are reversed at heights near the top of the boundary layer. This effect has previously been observed for nighttime temperatures above cities and termed a `crossover'. The mechanism proposed here to explain this new phenomenon, the daytime crossover, is similar to the previously suggested cause of the nighttime effect, that is, increased entrainment of warm dry air into the top of a cooler, more humid, boundary layer. The median summer daytime temperature crossover was found to be 1.1 K. The cooling was shown to be of a similar magnitude to the warming near the surface and extends up to 100 km downwind with a maximum magnitude at about 1500 UTC in summer. The moistening occurred over a similar spatial scale and peak values were typically two times greater than the near-surface drying effect.

  2. The role of one large greenspace in mitigating London's nocturnal urban heat island.

    2014-09-15

    The term urban heat island (UHI) describes a phenomenon where cities are on average warmer than the surrounding rural area. Trees and greenspaces are recognised for their strong potential to regulate urban air temperatures and combat the UHI. Empirical data is required in the UK to inform predictions on cooling by urban greenspaces and guide planning to maximise cooling of urban populations. We describe a 5-month study to measure the temperature profile of one of central London's large greenspaces and also in an adjacent street to determine the extent to which the greenspace reduced night-time UHI intensity. Statistical modelling displayed an exponential decay in the extent of cooling with increased distance from the greenspace. The extent of cooling ranged from an estimated 20 m on some nights to 440 m on other nights. The mean temperature reduction over these distances was 1.1 °C in the summer months, with a maximum of 4 °C cooling observed on some nights. Results suggest that calculation of London's UHI using Met Stations close to urban greenspace can underestimate 'urban' heat island intensity due to the cooling effect of the greenspace and values could be in the region of 45% higher. Our results lend support to claims that urban greenspace is an important component of UHI mitigation strategies. Lack of certainty over the variables that govern the extent of the greenspace cooling influence indicates that the multifaceted roles of trees and greenspaces in the UK's urban environment merit further consideration.

    Health forecasting can improve health service provision and individual patient outcomes. Environmental factors are known to impact chronic respiratory conditions such as asthma, but little is known about the extent to which these factors can be used for forecasting. Using weather, air quality and hospital asthma admissions, in London (2005-2006), two related negative binomial models were developed and compared with a naive seasonal model. In the first approach, predictive forecasting models were fitted with 7-day averages of each potential predictor, and then a subsequent multivariable model is constructed. In the second strategy, an exhaustive search of the best fitting models between possible combinations of lags (0-14 days) of all the environmental effects on asthma admission was conducted. Three models were considered: a base model (seasonal effects), contrasted with a 7-day average model and a selected lags model (weather and air quality effects). Season is the best predictor of asthma admissions. The 7-day average and seasonal models were trivial to implement. The selected lags model was computationally intensive, but of no real value over much more easily implemented models. Seasonal factors can predict daily hospital asthma admissions in London, and there is a little evidence that additional weather and air quality information would add to forecast accuracy.

    STUDY OBJECTIVE--To determine the cause of an outbreak of acute gastrointestinal illness that occurred shortly after lunch in children attending a school in London, UK. DESIGN--A questionnaire survey of children at the affected school was carried out on the day after the incident. Microbiological, environmental, and toxicological investigations were also undertaken. SETTING--A school in London, UK. PARTICIPANTS--Altogether 374/468 (80%) of the children who had eaten lunch at the school on the day of the incident completed a questionnaire. MAIN RESULTS--There was a significant association between illness and the consumption of raw cucumber (relative risk = 6.1; 95% confidence interval 2.2, 16). Microbiological investigation of the foods served at lunch did not show any pathogens and toxicological investigations suggested that the cucumbers were contaminated by a pesticide. CONCLUSIONS--Although the outbreak displayed several typical features of mass psychogenic illness, the most probable cause was a toxic chemical present in cucumber served at lunch. Those responsible for investigating outbreaks of illness should be aware of the possible toxicological causes and the appropriate modes of investigation. They should be wary of too readily attributing a psychogenic cause to unusual outbreaks of acute illness in schoolchildren. PMID:8138768

    During a 'Well London' study, residents were asked about their neighbourhood and its environment. Above all other complaints, 'dog poo' was mentioned as a key concern. Despite low rates of infection and disease among the human population resulting from contact with canine faecal matter, the concerns of the public continue to rate it as a serious public health issue. Most public health studies, therefore, seek to identify processes of transmission and disease pathology as a method of addressing the problem. This study approaches the issue through a contextualised analysis of residents' complaints, using anthropological theory to examine the symbolic representation of 'dog poo'. Analysis of the interviews shows that these specific complaints were located among less easily defined or articulated experiences of social and environmental neglect, where neighbours were estranged from one another and local authorities seen as negligent. This approach has important implications for public health, as it provides not only a strong indicator of the level of dissatisfaction within some of London's more disadvantaged neighbourhoods, but also identifies a need for policies that are grounded in cross-disciplinary research into the relationship between health, 'wellbeing' and experiences of marginalisation among urban populations.

    Major terrorist events, such as the recent attacks in Ankara, Sinai, and Paris, can have profound effects on a nation's values, attitudes, and prejudices. Yet psychological evidence testing the impact of such events via data collected immediately before and after an attack is understandably rare. In the present research, we tested the independent and joint effects of threat (the July 7, 2005, London bombings) and political ideology on endorsement of moral foundations and prejudices among two nationally representative samples (combined N = 2,031) about 6 weeks before and 1 month after the London bombings. After the bombings, there was greater endorsement of the in-group foundation, lower endorsement of the fairness-reciprocity foundation, and stronger prejudices toward Muslims and immigrants. The differences in both the endorsement of the foundations and the prejudices were larger among people with a liberal orientation than among those with a conservative orientation. Furthermore, the changes in endorsement of moral foundations among liberals explained their increases in prejudice. The results highlight the value of psychological theory and research for understanding societal changes in attitudes and prejudices after major terrorist events.

    Tower Hamlets (London, England) has a sizable Somali community whose members maintain close links with their families in Africa. The London Black Women's Health Action Project (LBWAP) was established in Tower Hamlets, in 1982, to address the health needs of Somali women, especially those related to female circumcision. The major focus in the UK has been on protecting girls from undergoing this practice, with little attention to the needs of women who have already been circumcised. Of 200 Somali women interviewed by LBWAP, 61% had been infibulated in their native country by people with no medical training. Among the long-term health consequences were dysmenorrhea, recurrent urinary problems, urethral damage, and painful intercourse. Although deinfibulation can be obtained, both health care professionals and circumcised women tend to be unaware of this service. LBWAP has proposed a study to assess the expressed health care needs of circumcised Somali women and match these desires with actual health care provision. To raise the consciousness of British health care professionals, parallels between female circumcision and the indiscriminate, unnecessary use of episiotomy are being made.

    2015-12-01

    At the Eighth International London Cough Conference held in London in July 2014, the focus was on the relatively novel concept of cough hypersensitivity syndrome (CHS) as forming the basis of chronic cough. This concept has been formulated following understanding of the neuronal pathways for cough and a realisation that not all chronic cough is usually associated with a cause. The CHS is defined by troublesome coughing triggered by low level of thermal, mechanical or chemical exposure. It also encompasses other symptoms or sensations such as laryngeal hypersensitivity, nasal hypersensitivity and possibly also symptoms related to gastrooesopahgeal reflux. The pathophysiologic basis of the CHS is now being increasingly linked to an enhancement of the afferent pathways of the cough reflex both at the peripheral and central levels. Mechanisms involved include the interactions of inflammatory mechanisms with cough sensors in the upper airways and with neuronal pathways of cough, associated with a central component. Tools for assessing CHS in the clinic need to be developed. New drugs may be developed to control CHS. A roadmap is suggested from the inception of the CHS concept towards the development of newer antitussives at the Symposium.

    Neuropsychological models propose qualitatively distinct planning impairments in the psychomotor poverty and disorganization syndromes in schizophrenia. It was proposed that poor plan initiation in psychomotor poverty would lead to longer initial planning times, while poor plan execution in disorganization would lead to greater inefficiency. Participants with psychomotor poverty (n = 30) and disorganization (n = 29) symptoms were contrasted with healthy controls (n = 28) to elucidate distinct planning impairments. Planning was compared in the Tower of London task versus real life analogue performance in the form of a board-game style diary planning task. The specificity of planning impairments was investigated by controlling for current IQ. The disorganization group demonstrated inefficient planning across both tasks, with poor performance on the Tower of London but not on the real life analogue task remaining after intelligence levels were taken into account. Initial planning times did not differ between groups. Previous associations between poor planning and symptoms may have been driven by poor planning with disorganization symptoms and associated lower order impairments in executive function or the semantic system. Targeting these impairments in people with disorganization symptoms may lead to a greater chance of success in promoting generalization to the real world.

  10. Postcode Lotteries in Public Health - The NHS Health Checks Programme in North West London

    2011-01-01

    Background Postcode lotteries in health refer to differences in health care between different geographic areas. These have been previously associated with clinical services. However there has been little documentation of postcode lotteries relating to preventative health care services. This paper describes a postcode lottery effect in relation to the NHS Health Checks Programme (a national cardiovascular screening programme in England) in eight PCTs in the North West sector of London. Methods A descriptive cross-sectional analysis of the Health Checks Programme was carried out in eight PCTs in North West London using a structured data-collecting instrument. Results The analysis found variation in the implementation of the national Health Checks Programme in terms of: the screening approach taken; the allocated budget (which varied from £69,000 to £1.4 million per 100,000 eligible population); payment rates made to providers of Health Checks; tools used to identify and measure risk of cardiovascular disease and diabetes; monitoring and evaluation; and preventative services available following the health check. Conclusions This study identifies a postcode lottery effect related to a national public health programme. Although it is important to allow enough flexibility in the design of the Health Checks Programme so that it fits in with local factors, aspects of the programme may benefit from greater standardisation or stronger national guidance.

    The objective was to examine the extent to which people living with HIV in London reported being discriminated against because of their infection. In 2004-2005, people living with HIV attending NHS outpatient HIV clinics in north east London were asked: "Have you ever been treated unfairly or differently because of your HIV status-in other words discriminated against?". Of the 1,687 people who returned a questionnaire (73% response rate), data from 1,385 respondents were included in this analysis; 448 heterosexual women and 210 heterosexual men of black African origin, 727 gay/bisexual men (621 white, 106 ethnic minority). Overall, nearly one-third of respondents (29.9%, 414/1,385) said they had been discriminated against because of their HIV infection. Of those who reported experiencing HIV-related discrimination, almost a half (49.6%, 200/403) said this had involved a health care worker including their dentist (n = 102, 25.3%) or primary care physician (n = 70, 17.4%).

    2015-01-01

    The first exemplar of a kiwi, the wingless bird of New Zealand, arrived in the form of a lifeless specimen in Europe in 1812. A debate was sparked over the appearance and nature of this strange creature and indeed whether it actually existed. In 1833 the Transactions of the Zoological Society of London entered the debate and the illustrations published in this journal contributed greatly to the acceptance and further study of the kiwi. Some of the most eminent British zoologists and anatomists of the time were involved, from William Yarrell to Richard Owen, and from John Gould to Abraham Dee Bartlett. This crucial period in the discussion, which would extend over two decades and would only be brought to a close with the arrival of the first living specimen in the London Zoological Garden in 1851, will be analyzed based on a detailed examination of the reports published in the Transactions and other journals. This essay will show how images of the bird were produced and used by zoologists during different stages in the early research on the bird and how these figures circulated inside and outside the zoologists' community.

    2015-01-01

    London (2014) provides an interesting article which presents a study of pegmatite zonation which is of considerable interest to students of pegmatites. However, although there is much to recommend it we take exception to his attempts to dismiss an extensive body of work on the use of melt inclusions to address the critical question of actual melt compositions during the evolution of pegmatites. Volatiles are by definition fugitive, since they are readily lost by degassing, and yet they are clearly critical to the growth of the large crystals which are a defining characteristic of pegmatites (e.g. Bartoli et al., 2014; Bowen, 1956; London, 2008; Lowenstern, 2003). Any research technique which can address the pre-degassing melt compositions should therefore be considered on its merits. Although melt inclusion studies are of relatively recent vintage the problems and possible questions of interpretation have been addressed in considerable detail for at least the last two decades (e.g. Lowenstern, 2003, and references therein) and recently in Audétat and Lowenstern (2014). Likewise, any discussion needs to cover "simple" quartz-feldspar-muscovite pegmatites (e.g. Thomas et al., 2009b), as well as the much less common if more interesting rare-element rich pegmatites (e.g. Thomas et al., 2009a).

    Background & Objective: The purpose of the study was to understand the dependency on smokeless tobacco. Methods: The major aspect of the interview was to study the type of chewing tobacco used, frequency of purchase of chewing tobacco, change in attitude and behavior after the use of chewing tobacco. This study was done in 2005 in London. Of the 110 respondents interviewed 88 were used for the data analysis. Study Design: An exploratory study was conducted in East London, United Kingdom. The selected sample was interviewed through a questionnaire, based on the Severson Smokeless Tobacco Dependence Scale. Results: Cross tabulations report that in a sample of 88 South Asian UK resident men 46.6% used leaf (paan), 43.2% used processed form of chewing tobacco and 10.2% used gutka. Older age (67%) respondents were more likely than the younger age (30%) respondents to chew tobacco. The frequency of purchase of chewing tobacco is reported high (67.2%) in the older age group than the younger age group (50%). Conclusion: This current study used an amended form of the Severson Smokeless Tobacco Scale questionnaire to study the dependency on smokeless tobacco. The study could be developed in the selection of the sample, which would include both males and females to study the dependency on smokeless tobacco. PMID:26234985

    Nanotechnology research is booming worldwide, and the general belief is that medical and biological applications will form the greatest sector of expansion over the next decade, driven by an attempt to bring radical solutions to areas of unmet medical need. What is true in the United States is also being fulfilled in Europe. This, though, is generally at a significantly lower investment level, even if for "large" capital infrastructure and interdisciplinary centers. Against this, the United Kingdom and its European partners are following the maxim "small is beautiful" and are attempting to identify and develop academic research and commercial businesses in areas that traditional nanotechnology developments involving engineering or physics find challenging. Thus in London-University College London (UCL) in a major joint project with Imperial College and linked to other UK and European centers of excellence-we are building upon our internationally competitive medical research (the two universities together form one of the largest centers of biomedical research outside the United States) to focus on and develop medical nanotechnology as a major sector of our research activity. A novel approach to commercialization has been the establishment with government and private equity funds of a "BioNanotechnology Centre" that will act as a portal for UK industry to access specialist skills to solve issues relating to developing nanotechnology-based medical applications, for example, for environmental screening, diagnostics, and therapy. This article reviews our academic and business strategy with examples from our current biomedical research portfolio.

    There are no studies that have examined the particular needs and experiences of African women living with HIV in the UK at a time when they represent an increasingly large proportion of the UK HIV epidemic. This study explores the illness biographies and daily lives of HIV-positive African women receiving treatment in London. Sixty-two women from 11 African countries attending HIV specialist clinics in five London hospitals participated in self-completion questionnaires and in depth semi-structured interviews. Using a narrative approach, women were asked to talk about their HIV status in the broader context of their life history. Important differences exist within this group based mainly on nationality, income, education level and legal status in the UK. However, marked similarities also emerged which were related in part to their situation as migrants and were compounded by their illness. Stigma, both actual and perceived, had a profound impact on women's lives, making control of information about their situation a matter of acute concern. This had an effect on how women accessed health services and voluntary sector agencies. The resilience of women in dealing with difficulties in their lives was strengthened by religious belief. Such similarities and differences need to be properly understood by health and social care professionals if they are to offer the most appropriate care for this growing population of patients.

    Arterial stiffening is not a new issue in medicine or research but was the prime concern of Richard Bright in the early 19th century and of the prominent London physicians and pathologists who tried to unscramble the relationship between kidney, heart, and cerebrovascular disease and hardness of the pulse in the late 19th century. It was of major concern to medical educators including Osler and Mackenzie who were still active in practice 100 years ago. It is all too easy (when dependent on the Internet) to consider arterial stiffness to be a new issue. The terms arterial stiffness, aortic stiffness, or wave reflection do not appear as categories for articles such as this in respectable journals, nor in categories for meetings of specialized physicians. Yet as described in this article, the subject was of interest to clinicians, to investigators such as Harvey in the 17th century, and to physicists who developed laws and principles of elasticity from the study of biological materials including ligaments and arteries. This paper provides a perspective on arterial stiffness from the time of William Harvey and Isaac Newton to the present, with a glance into the future.

  6. Mineral waters, electricity, and hemlock: devising therapeutics for children in eighteenth-century institutions.

    The development of paediatric medicine as a formal field of medical specialisation is usually traced to the mid-nineteenth century at the earliest. While it is true that formal specialisation in children's medicine was not, on the whole, typical for eighteenth-century medical practitioners, many displayed a deep and lasting interest in the diseases of children, and were consequently eager to develop therapeutic practices which could be targeted at infants and children. This led to a variety of attempts at innovation, many of which benefitted from the co-operation of, and opportunities afforded by, institutions. By examining the efforts of several medical practitioners at the London Foundling Hospital and at the Dispensary for the Infant Poor, this article explores how eighteenth-century medical practitioners used their affiliations with institutions to address the problems of devising or adapting therapeutic practices and treatments for children. In tailoring medical practice to suit children and, more specifically, in using institutions to do so, medical practitioners were demonstrating that child patients required special consideration, that children's diseases could be managed medically and with the benefit of new approaches and methods, and that children's health, as a whole, was the province of medical practitioners.

    Mercury has a long history, fascinating in its many aspects. Through the centuries--from ancient times to the present day--the metal in its various forms, also known under the name "quicksilver", accompanied the man and was used for diversified purposes. Today, mercury is employed in manufacturing thermometers, barometers, vacuum pumps and explosives. It is also used in silver and gold mining processes. Mercury compounds play a significant role in dentistry, pharmaceutical industry and crop protection. The contemporary use of mercury markedly decreases, but historically speaking, the archives abound in materials that document facts and events occurring over generations and the immense intellectual effort aiming at discovering the true properties and mechanisms of mercury activity. Mercury toxicity, manifested in destruction of biological membranes and binding of the element with proteins, what disturbs biochemical processes occurring in the body, was discovered only after many centuries of the metal exerting its effect on the lives of individuals and communities. For centuries, mercury was present in the work of alchemists, who searched for the universal essence or quintessence and the so-called philosopher's stone. In the early modern era, between the 16th and 19th centuries, mercury was used to manufacture mirrors. Mercury compounds were employed as a medication against syphilis, which plagued mankind for more than four hundred years--from the Middle Ages till mid 20th century, when the discovery of penicillin became the turning point. This extremely toxic therapy resulted in much suffering, individual tragedies, chronic poisonings leading to fatalities and dramatic sudden deaths. In the last fifty years, there even occurred attempts of mentally imbalanced individuals at injecting themselves with metallic mercury, also as a performance-enhancing drug. Instances of mass mercury poisoning occurred many times in the past in consequence of eating food products

  8. Dr. William Waugh (1851–1936): promoter of change in nineteenth century medical education and practice

    SUMMARY Dr. William E. Waugh (1851–1936) witnessed and actively participated in many changes in medical education and practice during his 6 decades in medicine. Trained as a surgeon and general practitioner, Waugh practised medicine in London, Ont., during the late nineteenth and early twentieth centuries. Early in his career, he embraced the new field of microbiology; refused outdated practices, such as bleeding; and dared to form a medical school despite strong criticism. Waugh was one of the founders of the Western University medical school, and he served various teaching and administrative roles in addition to maintaining a successful practice. He reminded students of the role of the physician’s senses, which he cautioned were in danger of being eclipsed, rather than supplemented, by the diagnostic instruments being adopted into clinical practice.

    It was exactly 300 years ago this month (August 1974) that the 17th century modest draper from Delft, Holland--Antony van Leeuwenhoek--discovered protozoa. Describing them, often with amazing accuracy considering the optical equipment he was using (simply a home-made "glorified" hand lens), in letters to the Royal Society of London, he established himself, certainly, as the founding father of protozoology. It is particularly appropriate for an assemblage of protozoologists to pay homage to this intrepid "philosopher in little things," a man with an insatiable curiosity about his wee animalcules, on the tricentenary of his discovery of them, since it was an event of such long-lasting significance.

  10. Head injuries in the 18th century: the management of the damaged brain.

    The 18th century was the time when trauma neurosurgery began to develop into the modern discipline. Before this, the management had, for the most part, changed little from the days of Hippocrates, Celsus, and Galen. Attention was directed to skull injuries, and the brain was treated as the seat of the rational soul but without other function. Symptoms after trauma were attributed to injuries to the bone and meninges. Following the lead of the Royal Academy of Surgery in Paris, it was accepted from the 1730s that the brain was the seat of symptoms after cranial trauma. During the 18th century, at least 12 surgeons published articles on cranial injury, 6 describing significant clinical series on this topic. They were Henri-François Le Dran (1685-1770) of Paris, Percival Pott (1714-1788) of London, James Hill (1703-1776) from Dumfries, Sylvester O'Halloran (1728-1807) of Limerick (Ireland), William Dease (1750-1798) of Dublin, and John Abernethy (1764-1831) of London. This article analyzes these series. Each individual made a different contribution. It is suggested that the relatively lesser-known James Hill in Scotland demonstrated the greatest understanding of the management of brain trauma and achieved the best results. A product of the Scottish Enlightenment, he adapted his management to his own experience and was not tied to the accepted authorities of his day, but he improved the management of each case following his experience with previous patients. He deserves to be remembered.

    Air quality in urban areas represents a major public health issue with around one third of the European population concentrated in cities and numbers expected to increase at global scale, particularly in developing countries. Particulate matter (PM) represents a primary threat for human health as numerous studies have confirmed the association between increased levels of cardiovascular and respiratory diseases with the exposure to PM. Despite considerable efforts made in improving air quality and progressively stricter emissions regulations, the PM concentrations have not changed much over the past decades for reasons that remain unclear, and highlight that studies on PM source apportionment are required for the formulation of effective policy. We investigated the chemical composition of organic aerosol (OA) collected during two intensive field campaigns held in winter and summer 2012 in the frame of the project Clean air for London (http://www.clearflo.ac.uk/). PM samples were collected both at a city background site (North Kensington) and at a rural site 50 km southeast of London (Detling) with 8 to 24 hours sampling schedule and analysed using off-line methods. Thermal-optical analysis was used to quantify OC-EC components while a suite of soft ionization mass spectrometric techniques was deployed for detailed chemical characterization. Liquid chromatography mass Spectrometry (LC-MSn) was mostly used for the simultaneous detection and quantification of various tracers for both primary and secondary OA sources. Well-established markers for wood burning primary OA like levoglucosan and azelaic acid were quantified together with various classes of nitroaromatics including methyl-nitrocatechols that are potential tracers for wood burning secondary OA. In addition, oxidation products of biogenic VOCs such as isoprene and monoterpenes were also quantified for both seasons and sites. A non-negligible contribution from biogenic SOA to urban OA was found in summertime

    Near-continuous measurements of hydroxyl radical (OH) reactivity in the urban background atmosphere of central London during the summer of 2012 are presented. OH reactivity behaviour is seen to be broadly dependent on air mass origin, with the highest reactivity and the most pronounced diurnal profile observed when air had passed over central London to the east, prior to measurement. Averaged over the entire observation period of 26 days, OH reactivity peaked at ˜ 27 s-1 in the morning, with a minimum of ˜ 15 s-1 during the afternoon. A maximum OH reactivity of 116 s-1 was recorded on one day during morning rush hour. A detailed box model using the Master Chemical Mechanism was used to calculate OH reactivity, and was constrained with an extended measurement data set of volatile organic compounds (VOCs) derived from a gas chromatography flame ionisation detector (GC-FID) and a two-dimensional GC instrument which included heavier molecular weight (up to C12) aliphatic VOCs, oxygenated VOCs and the biogenic VOCs α-pinene and limonene. Comparison was made between observed OH reactivity and modelled OH reactivity using (i) a standard suite of VOC measurements (C2-C8 hydrocarbons and a small selection of oxygenated VOCs) and (ii) a more comprehensive inventory including species up to C12. Modelled reactivities were lower than those measured (by 33 %) when only the reactivity of the standard VOC suite was considered. The difference between measured and modelled reactivity was improved, to within 15 %, if the reactivity of the higher VOCs (⩾ C9) was also considered, with the reactivity of the biogenic compounds of α-pinene and limonene and their oxidation products almost entirely responsible for this improvement. Further improvements in the model's ability to reproduce OH reactivity (to within 6 %) could be achieved if the reactivity and degradation mechanism of unassigned two-dimensional GC peaks were estimated.

    The composition of PM1 (particulate matter with diameter less than 1 μm) in the greater London area was characterized during the Clean Air for London (ClearfLo) project in winter 2012. Two High-Resolution Time-of-Flight Aerosol Mass Spectrometers (HR-ToF-AMS) were deployed at a rural site (Detling, Kent) and an urban site (North Kensington, London). The simultaneous and high-temporal resolution measurements at the two sites provide a unique opportunity to investigate the spatial distribution of PM1. We find that the organic aerosol (OA) concentration is comparable between the rural and urban sites, but the sources of OA are distinctly different. The concentration of solid fuel OA at the urban site is about twice as high as at the rural site, due to elevated domestic heating in the urban area. While the concentrations of oxygenated OA (OOA) are well-correlated between the two sites, the OOA concentration at the rural site is almost twice that of the urban site. At the rural site, more than 70 % of the carbon in OOA is estimated to be non-fossil, which suggests that OOA is likely related to aged biomass burning considering the small amount of biogenic SOA in winter. Thus, it is possible that the biomass burning OA contributes a larger fraction of ambient OA in wintertime than what previous field studies have suggested. A suite of instruments was deployed downstream of a thermal denuder (TD) to investigate the volatility of PM1 species at the rural Detling site. After heating at 250 °C in the TD, 40 % of the residual mass is OA, indicating the presence of non-volatile organics in the aerosol. Although the OA associated with refractory black carbon (rBC, measured by a soot-particle aerosol mass spectrometer) only accounts for < 10 % of the total OA (measured by a HR-ToF-AMS) at 250 °C, the two measurements are well-correlated, suggesting that the non-volatile organics have similar sources or have undergone similar chemical processing as rBC in the atmosphere

    For the first time, the behaviour of non-refractory inorganic and organic submicron particulate through an entire annual cycle is investigated using measurements from an Aerodyne compact time-of-flight aerosol mass spectrometer (cToF-AMS) located at a UK urban background site in North Kensington, London. We show that secondary aerosols account for a significant fraction of the submicron aerosol burden and that high concentration events are governed by different factors depending on season. Furthermore, we demonstrate that on an annual basis there is no variability in the extent of secondary organic aerosol (SOA) oxidation, as defined by the oxygen content, irrespective of amount. This result is surprising given the changes in precursor emissions and contributions as well as photochemical activity throughout the year; however it may make the characterisation of SOA in urban environments more straightforward than previously supposed. Organic species, nitrate, sulphate, ammonium, and chloride were measured during 2012 with average concentrations (±1 standard deviation) of 4.32 (±4.42), 2.74 (±5.00), 1.39 (±1.34), 1.30 (±1.52), and 0.15 (±0.24) μg m-3, contributing 44, 28, 14, 13, and 2 % to the total non-refractory submicron mass (NR-PM1) respectively. Components of the organic aerosol fraction are determined using positive matrix factorisation (PMF), in which five factors are identified and attributed as hydrocarbon-like OA (HOA), cooking OA (COA), solid fuel OA (SFOA), type 1 oxygenated OA (OOA1), and type 2 oxygenated OA (OOA2). OOA1 and OOA2 represent more and less oxygenated OA with average concentrations of 1.27 (±1.49) and 0.14 (±0.29) μg m-3 respectively, where OOA1 dominates the SOA fraction (90%). Diurnal, monthly, and seasonal trends are observed in all organic and inorganic species due to meteorological conditions, specific nature of the aerosols, and availability of precursors.

    The growing demand for air travel in the UK has led to calls for ways to address the effects of increasing activities in airports in London. London Heathrow airport (LHR) is the largest airport in the UK and in recent years has been operating close to full capacity resulting in consideration of building a third runway to ease the burden at the airport. Such an expansion would be subject to meeting several criteria including local air quality challenges. Air quality issues associated with the airport include particulates (e.g. PM2.5, PM10), carbon monoxide (CO), oxides of nitrogen (NO, NO2), sulphur dioxide (SO2) and volatile organic compounds (VOCs), and these are associated with different sources including aircraft activities and road traffic within and outside of the airport. Although it is well known that airports contribute to poor air quality, part of the challenge is to quantify contributions from these different sources. The work presented here shows the utility of low-cost high density sensor networks in addressing this challenge. We have shown in previous studies the application of low-cost electrochemical sensor network instruments in monitoring air quality pollutants including CO, NO and NO2 in an urban environment. In this paper we extend this to include modified versions of these instruments which incorporate additional species such as O3, SO2, VOCs, CO2 as well as size-speciated particulates (0.38 to 17.4 μm). Meteorological data including temperature, relative humidity, wind speed and direction are also recorded. For this paper, we focus on LHR, although the technique has much wider applicability. A network of 30 sensor nodes is being deployed for over 16 months in and around LHR as part of NERC funded Sensor Network for Air Quality (SNAQ) project. We present here some of the early results from the deployment showing source attribution associated with different operational modes at LHR.

    Volatile organic compounds (VOCs) from anthropogenic sources such as fuel combustion or evaporative emissions can directly and indirectly affect human health. Some VOCs, such as benzene and 1,3- butadiene are carcinogens. These and other VOCs contribute to the formation of ozone (O3) and aerosol particles, which have effects on human health and the radiative balance of the atmosphere. Although in the UK VOC emissions are subject to control under European Commission Directive 2008/50/EC and emission reducing technologies have been implemented, urban air pollution remains a concern. Urban air quality is likely to remain a priority since currently >50% of the global population live in urban areas with trends in urbanization and population migration predicted to increase. The ClearfLo project is a large multi-institutional consortium funded by the UK Natural Environment Research Council (NERC) and provides integrated measurements of meteorology, gas phase and particulate composition of the atmosphere over London. Both long term and IOP measurements were made at street and elevated locations at a range of sites across London and its surroundings during 2011 and 2012. Mixing ratios of a selection of nine VOCs were measured using a high sensitivity proton transfer reaction-mass spectrometer (PTR-MS) at a ground level urban background (North Kensington) and kerbside (Marylebone Road) site during the winter IOP. VOC fluxes were measured by virtually disjunct eddy covariance (vDEC) at an elevated urban site (King's College Strand) in Aug-Dec 2012. Our results for the first IOP showed that most of the selected compound concentrations depended on traffic emissions, although there was a marked difference between the urban background and kerbside sites. We identified some temperature effects on VOC concentrations. We also present the first analyses of VOC flux measurements over London. Preliminary analyses indicate most compounds associated with vehicle emissions closely

    Urban authorities are continuously drawing up policies to promote cycling among commuters. However, these initiatives are counterproductive for the targeted objectives because they increase opportunities for bicycle theft. This paper explores Inner London as a case study to address place-specific risk factors for bicycle theft at the street-segment level while controlling for seasonal variation. The presence of certain public amenities (e.g., bicycle stands, railway stations, pawnshops) was evaluated against locations of bicycle theft between 2013 and 2016 and risk effects were estimated using negative binomial regression models. Results showed that a greater level of risk stemmed from land-use facilities than from area-based socioeconomic status. The presence of facilities such as train stations, vacant houses, pawnbrokers and payday lenders increased bicycle theft, but no evidence was found that linked police stations with crime levels. The findings have significant implications for urban crime prevention with respect to non-residential land use.

    We develop and apply a multilevel modeling approach that is simultaneously capable of assessing multigroup and multiscale segregation in the presence of substantial stochastic variation that accompanies ethnicity rates based on small absolute counts. Bayesian MCMC estimation of a log-normal Poisson model allows the calculation of the variance estimates of the degree of segregation in a single overall model, and credible intervals are obtained to provide a measure of uncertainty around those estimates. The procedure partitions the variance at different levels and implicitly models the dependency (or autocorrelation) at each spatial scale below the topmost one. Substantively, we apply the model to 2011 census data for London, one of the world's most ethnically diverse cities. We find that the degree of segregation depends both on scale and group.

    In 2008, guidelines aimed at reducing undiagnosed HIV infection were published, recommending normalization of testing. Local initiatives were carried out in south-west London including an extensive primary care education programme. This study aimed to establish the impact of these initiatives on HIV diagnoses. Data on all new diagnoses referred to our centre were collected and analysed from patient records. A total of 394 patients were newly diagnosed with HIV from 2007 to 2011. Diagnosis in primary care and other non-sexual health (SH) settings increased by 184% during this period. There was an increase of 37% in the median CD4 count at diagnosis, taking the figure to 372 cells/mm³ in 2011. The proportion of patients presenting with a CD4 count of <200cells/mm³ decreased by 24%. The evidence suggests that these local initiatives were successful in increasing HIV diagnoses outside SH settings, particularly in very late presenters.

  5. Change in Urban Albedo in London: A Multi-scale Perspective

    Susca, T.; Kotthaus, S.; Grimmond, S.

    2013-12-01

    Urbanization-induced change in land use has considerable implications for climate, air quality, resources and ecosystems. Urban-induced warming is one of the most well-known impacts. This directly and indirectly can extend beyond the city. One way to reduce the size of this is to modify the surface atmosphere exchanges through changing the urban albedo. As increased rugosity caused by the morphology of a city results in lower albedo with constant material characteristics, the impacts of changing the albedo has impacts across a range of scales. Here a multi-scale assessment of the potential effects of the increase in albedo in London is presented. This includes modeling at the global and meso-scale informed by local and micro-scale measurements. In this study the first order calculations are conducted for the impact of changing the albedo (e.g. a 0.01 increase) on the radiative exchange. For example, when incoming solar radiation and cloud cover are considered, based on data retrieved from NASA (http://power.larc.nasa.gov/) for ~1600 km2 area of London, would produce a mean decrease in the instantaneous solar radiative forcing on the same surface of 0.40 W m-2. The nature of the surface is critical in terms of considering the impact of changes in albedo. For example, in the Central Activity Zone in London pavement and building can vary from 10 to 100% of the plan area. From observations the albedo is seen to change dramatically with changes in building materials. For example, glass surfaces which are being used increasingly in the central business district results in dramatic changes in albedo. Using the documented albedo variations determined across different scales the impacts are considered. For example, the effect of the increase in urban albedo is translated into the corresponding amount of avoided emission of carbon dioxide that produces the same effect on climate. At local scale, the effect that the increase in urban albedo can potentially have on local

    We study the opportunistic political budget cycle in the London Metropolitan Boroughs between 1902 and 1937 under two different suffrage regimes: taxpayer suffrage (1902–1914) and universal suffrage (1921–1937). We argue and find supporting evidence that the political budget cycle operates differently under the two types of suffrage. Taxpayer suffrage, where the right to vote and the obligation to pay local taxes are linked, encourages demands for retrenchment and the political budget cycle manifests itself in election year tax cuts and savings on administration costs. Universal suffrage, where all adult residents can vote irrespective of their taxpayer status, creates demands for productive public services and the political budget cycle manifests itself in election year hikes in capital spending and a reduction in current spending.

  7. Ali, Cunich: Halley's Churches: Halley and the London Queen Anne Churches

    Edmond Halley's enormous contribution to science has received much attention. New research adds an intriguing chapter to his story and concerns his hitherto unexplored association with the baroque architectural visionary Nicholas Hawksmoor, and some important Temple-inspired churches that were built in London in the early 1700s. We argue that Christchurch Spitalfields and St Anne's Limehouse, which were both started in the summer of 1714, were aligned exactly eastwards using ``corrected'' magnetic-compass bearings and that Halley influenced or aided Hawksmoor. By this time the men had probably known each other for 30 years and had recently worked together on the Clarendon Building in Oxford. Despite there being more than 1500 years of Chinese and about 500 years of Western compass technology at the time, these probably represent the first constructions planned using a modern-day ``scientific'' technique. The research also throws light on Halley's contended religious position.

  8. Legality of seabed disposal of high-level radioactive wastes under the London Dumping Convention

    Disposal of high-level wastes in seabed sediments is the subject of ongoing technical, environmental, and engineering feasibility studies by several countries. In the London Dumping Convention (LDC's) definition of dumping, the phrase disposal at sea could be interpreted narrowly to mean the final resting place of wastes with seabed disposal excluded from coverage because those wastes are not in direct contact with marine waters. Given the LDC's object and purpose, though, the only harmonious and reasonable interpretation is that which defines disposal at sea to mean the place where the dumping activities occur. Other international agreements also support this object and purpose-based interpretation which concludes that seabed disposal is covered and prohibited. In addition, this approach is preferred because it contributes to the continued effectiveness of the LDC. 1 figure, 2 tables.

    The present study examined age differences in performance on the Tower of London, a measure of strategic planning, in a diverse sample of 890 individuals between the ages of 10 and 30. Although mature performance was attained by age 17 on relatively easy problems, performance on the hardest problems showed improvements into the early 20s. Furthermore, whereas age-related performance gains by children and adolescents (ages 10-17) on the hardest problems were partially mediated by maturational improvements in both working memory and impulse control, improved performance in adulthood (ages 18+) was fully mediated by late gains in impulse control. Findings support an emerging picture of late adolescence as a time of continuing improvement in planned, goal-directed behavior.

  10. Environmental Risk Factors influencing Bicycle Theft: A Spatial Analysis in London, UK

    2016-01-01

    Urban authorities are continuously drawing up policies to promote cycling among commuters. However, these initiatives are counterproductive for the targeted objectives because they increase opportunities for bicycle theft. This paper explores Inner London as a case study to address place-specific risk factors for bicycle theft at the street-segment level while controlling for seasonal variation. The presence of certain public amenities (e.g., bicycle stands, railway stations, pawnshops) was evaluated against locations of bicycle theft between 2013 and 2016 and risk effects were estimated using negative binomial regression models. Results showed that a greater level of risk stemmed from land-use facilities than from area-based socioeconomic status. The presence of facilities such as train stations, vacant houses, pawnbrokers and payday lenders increased bicycle theft, but no evidence was found that linked police stations with crime levels. The findings have significant implications for urban crime prevention with respect to non-residential land use. PMID:27643788

    An outbreak of cryptosporidiosis which affected 44 people in January and February 1991 was identified through local surveillance at a South London Public Health Laboratory. Preliminary enquiries revealed that more than half the patients were adult and that there were no common factors other than geographical association. A case-control study showed a significant association between illness and consumption of tap water supplied by a particular water company, as well as a dose response effect. There were no apparent breaches or irregularities in the water distribution system and no indication of a problem through routine monitoring indices. This incident demonstrates the problems of establishing the source of cryptosporidiosis outbreaks in the absence of evidence of environmental abnormality, as well as possibly indicating that water conforming to current treatment standards may occasionally contain sufficient numbers of Cryptosporidium oocysts to cause sporadic cases or clusters.

    Optimizing paths on networks is crucial for many applications, ranging from subway traffic to Internet communication. Because global path optimization that takes account of all path choices simultaneously is computationally hard, most existing routing algorithms optimize paths individually, thus providing suboptimal solutions. We use the physics of interacting polymers and disordered systems to analyze macroscopic properties of generic path optimization problems and derive a simple, principled, generic, and distributed routing algorithm capable of considering all individual path choices simultaneously. We demonstrate the efficacy of the algorithm by applying it to: (i) random graphs resembling Internet overlay networks, (ii) travel on the London Underground network based on Oyster card data, and (iii) the global airport network. Analytically derived macroscopic properties give rise to insightful new routing phenomena, including phase transitions and scaling laws, that facilitate better understanding of the appropriate operational regimes and their limitations, which are difficult to obtain otherwise.

    2004-01-01

    The association of aircraft noise exposure with cognitive performance was examined by means of a cross-sectional field survey. Two hundred thirty six children attending 10 primary schools around Heathrow Airport in west London were tested on reading comprehension, immediate/delayed recall and sustained attention. In order to obtain the information about their background, a questionnaire was delivered to the parents and 163 answers were collected. Logistic regression models were used to assess performance on the cognitive tests in relation to aircraft noise exposure at home and possible individual and school level confounding factors. A significant dose-response relationship was found between aircraft noise exposure at home and performance on memory tests of immediate/delayed recall. However there was no strong association with the other cognitive outcomes. These results suggest that aircraft noise exposure at home may affect children's memory.

  15. Endogenous steroids and financial risk taking on a London trading floor

    2008-01-01

    Little is known about the role of the endocrine system in financial risk taking. Here, we report the findings of a study in which we sampled, under real working conditions, endogenous steroids from a group of male traders in the City of London. We found that a trader's morning testosterone level predicts his day's profitability. We also found that a trader's cortisol rises with both the variance of his trading results and the volatility of the market. Our results suggest that higher testosterone may contribute to economic return, whereas cortisol is increased by risk. Our results point to a further possibility: testosterone and cortisol are known to have cognitive and behavioral effects, so if the acutely elevated steroids we observed were to persist or increase as volatility rises, they may shift risk preferences and even affect a trader's ability to engage in rational choice.

    This study investigated the distribution and diversity of epiphytes in London in relation to NO(x) using fine-scale atmospheric dispersion modelling. The survey recorded over 3000 epiphytes from 334 trees (Fraxinus excelsior) representing 74 lichen, 14 moss, 7 fungal and 3 algal species. There was a significant inverse relationship between diversity and NO(x). Diversity declined where NO(x) exceeded 70 microg m(-3) and NO2 exceeded 40 microg m(-3), suggesting a phytotoxic effect. However, there was a significant positive relationship between NO(x) and lichen abundance due to the ubiquitous distribution of pollution tolerant species, mainly associated with eutrophication. A scale of lichen sensitivity to NO(x) has been derived.

    Education is one major public service in which quasi-markets and other choice-based mechanisms are now established methods of delivery. The types of school people choose, and the extent to which their choices are realized, have a fundamental impact on the outcomes of any mechanism of school choice. In this article, we provide a comparative analysis of the school choice strategies of middle-class families in London and Paris. We draw on approximately 200 in-depth interviews carried out across the two cities. This enables us to investigate the extent to which middle-class school choice strategies transcend the institutional context provided by both the local (state and private) schools market and national education policy in England and France. We discuss these findings in the context of current school choice policy and consider their implications for future policy design. PMID:25750467

    The development of health policy is recognized as complex; however, there has been little development of the role of agency in this process. Kingdon developed the concept of policy entrepreneur (PE) within his ‘windows’ model. He argued inter-related ‘policy streams' must coincide for important issues to become addressed. The conjoining of these streams may be aided by a policy entrepreneur. We contribute by clarifying the role of the policy entrepreneur and highlighting the translational processes of key actors in creating and aligning policy windows. We analyse the work in London of Professor Sir Ara Darzi as a policy entrepreneur. An important aspect of Darzi's approach was to align a number of important institutional networks to conjoin related problems. Our findings highlight how a policy entrepreneur not only opens policy windows but also yokes together a network to make policy agendas happen. Our contribution reveals the role of clinical leadership in health reform.

    The Faraday Discussion on the design of new heterogeneous catalysts took place from 4-6 April 2016 in London, United Kingdom. It brought together world leading scientists actively involved in the synthesis, characterisation, modelling and testing of solid catalysts, attracting more than one hundred delegates from a broad spectrum of backgrounds and experience levels - academic and industrial researchers, experimentalists and theoreticians, and students. The meeting was a reflection of how big of an impact the ability to control and design catalysts with specific properties for particular processes can potentially have on the chemical industry, environment, economy and society as a whole. In the following, we give an overview of the topics covered during this meeting and briefly highlight the content of each presentation.

    Following the 2005 London bombings, a novel public health program was instituted to address the mental health needs of survivors. In this article, the authors describe the rationale for the program, characteristics of individuals assessed within the program, and preliminary outcome data. In addition to validated screening instruments and routine service usage data, standardized questionnaire outcome measures were collected. Seventy-one percent of individuals screened positive for a mental disorder. Of those receiving a more detailed clinical assessment, PTSD was the predominant diagnosis. Preliminary outcome data on 82 patients revealed large effect sizes for treatment comparable to those previously obtained in randomized controlled trials. The program succeeded in its aim of generating many more referrals of affected individuals than came through normal referral channels. PMID:18302178

    On-site field investigation was conducted to authenticate a batch of ancient Chinese medicinal decoction pieces that have been preserved in a rare collection at the Natural History Museum in London. These treasured artifacts comprise a portion of the Sloane Collection, and the nearly one hundred Chinese medicinal specimens examined within provide an objective record of the real situation regarding the Chinese medicinal materials in commercial circulation three hundred years ago. The precious data from this collection pro-vides an extremely valuable reference for the research into the history of medicinal exchange between China and the West during the Age of Exploration, shedding light on the evolution and historical changes in the species used in Chinese medicine, as well as the history of medicinal processing and decoction pieces.

    In 2009 the international agreement setting up the Roque de los Muchachos Observatory on the island of La Palma will have been in existence for a period of 30 years. In 2007 the United Kingdom will have to make a decision on whether or not to withdraw from that agreement and PPARC, through its ownership of the Isaac Newton Group of Telescopes, has the responsibility of deciding on the UK's involvement in the observatory beyond 2009. As part of the decision making process, and in support of the UK's overall strategic re-evaluation in astronomy, the ING was reviewed during 2005. It was therefore thought timely to assess recent scientific achievements from the Roque de los Muchachos, and to consider what role the observatory might have beyond 2009. Under the auspices of the Royal Astronomical Society a Specialist Meeting was held in Burlington House, Piccadilly, London on October 14th 2005 and was attended by approximately 100 astronomers from around the UK.

    This paper describes the design, construction, and operation of the London University Search Instrument (LUSI) which was recently commissioned to create and test combinatorial libraries of ceramic compositions. The instrument uses commercially available powders, milled as necessary to create thick-film libraries by ink-jet printing. Multicomponent mixtures are prepared by well plate reformatting of ceramic inks. The library tiles are robotically loaded into a flatbed furnace and, when fired, transferred to a 2-axis high-resolution measurement table fitted with a hot plate where measurements of, for example, optical or electrical properties can be made. Data are transferred to a dedicated high-performance computer. The possibilities for remote interrogation and search steering are discussed.

    Plantar fascia and distal Achilles injuries are common in elite athletes. Acute athletic injuries of the plantar fascia include acute plantar fasciopathy and partial or complete tears. Underlying most acute injuries is a background of underlying chronic plantar fasciopathy. Injuries may affect the central or less commonly lateral portions of the fascia and acute tears are generally proximal. Athletic Achilles injuries may occur at the mid tendon or the distal insertion, and there may be an underlying chronic tendinopathy. Acute or chronic paratendinopathy may occur as a separate entity or combined with Achilles injury. In this article, the spectrum of athletic injuries of the plantar fascia and Achilles is described, illustrated by imaging findings from the London 2012 Olympic games.

    Abstract The present catalogue lists the type specimens of land snail species, collected from Taiwan and deposited in the Natural History Museum, London. Thirty-seven nominal species described by Pfeiffer, Adams, Nevill, Moellendorff, Godwin-Austen and Gude were traced. I present here information on type status, collection data obtained from the registers and labels of each collection, and annotations on the current taxonomic affiliation. Lectotypes of 28 nominal (sub)species were newly designated. One holotype was fixed originally and two holotypes newly fixed by monotypy. Syntypes of two species and paralectotypes of three species were also discovered in the Museum. No specimen of the species Pupina adamsi Sowerby, 1878, which was supposed to be deposited in the NHM, was found. Pictures of the name-bearing types are provided for further research on biodiversity of the island. PMID:25901108

    Evidence on the effects of long-term exposure to traffic pollution on health is inconsistent. In Greater London we examined associations between traffic pollution and emergency hospital admissions for cardio-respiratory diseases by applying linear and piecewise linear Poisson regression models in a small-area analysis. For both models the results for children and adults were close to unity. In the elderly, linear models found negative associations whereas piecewise models found non-linear associations characterized by positive risks in the lowest and negative risks in the highest exposure category. An increased risk was observed among those living in areas with the highest socioeconomic deprivation. Estimates were not affected by adjustment for traffic noise. The lack of convincing positive linear associations between primary traffic pollution and hospital admissions agrees with a number of other reports, but may reflect residual confounding. The relatively greater vulnerability of the most deprived populations has important implications for public health.

  9. Evidence for the Continued Use of Medieval Medical Prescriptions in the Sixteenth Century: A Fifteenth-Century Remedy Book and its Later Owner.

    PubMed

    Connolly, Margaret

    2016-04-01

    This article examines a fifteenth-century remedy book, Oxford, Bodleian Library, Rawlinson c. 299, and describes its collection of 314 medieval medical prescriptions. The recipes are organised broadly from head to toe, and often several remedies are offered for the same complaint. Some individual recipes are transcribed with modern English translations. The few non-recipe texts are also noted. The difference between a remedy book and a leechbook is explained, and this manuscript is situated in relation to other known examples of late medieval medical anthologies. The particular feature that distinguishes Oxford, Bodleian Library, Rawlinson c. 299 from other similar volumes is the evidence that it continued to be used during the sixteenth century. This usage was of two kinds. Firstly, the London lawyer who owned it not only inscribed his name but annotated the original recipe collection in various ways, providing finding-aids that made it much more user-friendly. Secondly, he, and other members of his family, added another forty-three recipes to the original collection (some examples of these are also transcribed). These two layers of engagement with the manuscript are interrogated in detail in order to reveal what ailments may have troubled this family most, and to judge how much faith they placed in the old remedies contained in this old book. It is argued that the knowledge preserved in medieval books enjoyed a longevity that extended beyond the period of the manuscript book, and that manuscripts were read and valued long after the advent of printing.

    Although urban birth, upbringing, and living are associated with increased risk of nonaffective psychotic disorders, few studies have used appropriate multilevel techniques accounting for spatial dependency in risk to investigate social, economic, or physical determinants of psychosis incidence. We adopted Bayesian hierarchical modeling to investigate the sociospatial distribution of psychosis risk in East London for DSM-IV nonaffective and affective psychotic disorders, ascertained over a 2-year period in the East London first-episode psychosis study. We included individual and environmental data on 427 subjects experiencing first-episode psychosis to estimate the incidence of disorder across 56 neighborhoods, having standardized for age, sex, ethnicity, and socioeconomic status. A Bayesian model that included spatially structured neighborhood-level random effects identified substantial unexplained variation in nonaffective psychosis risk after controlling for individual-level factors. This variation was independently associated with greater levels of neighborhood income inequality (SD increase in inequality: Bayesian relative risks [RR]: 1.25; 95% CI: 1.04-1.49), absolute deprivation (RR: 1.28; 95% CI: 1.08-1.51) and population density (RR: 1.18; 95% CI: 1.00-1.41). Neighborhood ethnic composition effects were associated with incidence of nonaffective psychosis for people of black Caribbean and black African origin. No variation in the spatial distribution of the affective psychoses was identified, consistent with the possibility of differing etiological origins of affective and nonaffective psychoses. Our data suggest that both absolute and relative measures of neighborhood social composition are associated with the incidence of nonaffective psychosis. We suggest these associations are consistent with a role for social stressors in psychosis risk, particularly when people live in more unequal communities.

    Aims: To identify changes in the presenting number and species of imported malaria in children in southwest London. Methods: A prospective single observer study over 25 years (1975–99) of all cases of paediatric malaria seen at St George's Hospital. Results: A confirmed diagnosis was made in 249 children (56% boys; 44% girls; median age 8.0 years). Of these, 53% were UK residents and 44% were children travelling to the UK. A significant increase was noted in the number of cases over the 25 years (1975–79: mean 4.8 cases/year; 1990–99: mean 13.7 cases/year). Over the 25 years Plasmodium falciparum was seen in 77%, P vivax in 14%, P ovale in 6%, and P malariae in 3% of cases. P falciparum had increased in frequency (1975–79: P falciparum 50%, P vivax 50%; 1990–99: P falciparum 82%, P vivax 6%), associated with an increase in the proportion of children acquiring their infection in sub-Saharan Africa. Median time between arrival in the UK to the onset of fever was: P falciparum, 5 days; P ovale, 25 days; P malariae, 37 days; and P vivax, 62 days. Median time interval between the onset of fever to commencement of treatment was 4 days. This had not improved over the 25 year period. Only 41% of UK resident children presenting to hospital had taken prophylaxis and the overall number of symptomatic children taking no prophylaxis was increasing. Conclusion: Imported childhood P falciparum malaria is increasing in southwest London associated with increasing travel from sub-Saharan Africa. Over the 25 year period there has been no improvement in chemoprophylaxis rates or time to diagnosis. PMID:12023177

  13. Methodology for Airborne Quantification of NOx fluxes over Central London and Comparison to Emission Inventories

    The emission of pollutants is a major problem in today's cities. Emission inventories are a key tool for air quality management, with the United Kingdom's National and London Atmospheric Emission Inventories (NAEI & LAEI) being good examples. Assessing the validity of such inventoried is important. Here we report on the technical methodology of matching flux measurements of NOx over a city to inventory estimates. We used an eddy covariance technique to directly measure NOx fluxes from central London on an aircraft flown at low altitude. NOx mixing ratios were measured at 10 Hz time resolution using chemiluminescence (to measure NO) and highly specific photolytic conversion of NO2 to NO (to measure NO2). Wavelet transformation was used to calculate instantaneous fluxes along the flight track for each flight leg. The transformation allows for both frequency and time information to be extracted from a signal, where we quantify the covariance between the de-trended vertical wind and concentration to derive a flux. Comparison between the calculated fluxes and emission inventory data was achieved using a footprint model, which accounts for contributing source. Using both a backwards lagrangian model and cross-wind dispersion function, we find the footprint extent ranges from 5 to 11 Km in distance from the sample point. We then calculate a relative weighting matrix for each emission inventory within the calculated footprint. The inventories are split into their contributing source sectors with each scaled using up to date emission factors, giving a month; day and hourly scaled estimate which is then compared to the measurement.

High-resolution microscopy identified most of the material as soot with smelter spheres, fly ash (FA), sodium chloride and calcium sulphate particles. Image analysis (IA) was used to show that most of the soot aggregates were less than 1 microm in size and contained chains of individual particles of 10-50 nm. Speed mapping of large agglomerates of the historic particles confirmed that the samples were enriched with soot probably derived from a sulphur-rich coal called nutty slack which was used extensively at this time. Inductively coupled plasma-mass spectrometry (ICP-MS) was used to examine elemental composition. Meaningful quantitation of certain elements (Mg, Al and Zn) proved impossible because they were in high quantities in the glass fibre filters. However, high quantities of Fe>Pb>Cu>Mn>V>As were detected which may explain in part the bioreactivity of the samples. Using a simple in vitro test of oxidative capacity (plasmid assay), one historic particulate sample (1958) showed three times the activity of a modern-day diesel exhaust particle (DEP) sample but ten times less activity than a modern-day urban ambient particle collection. Such studies are continuing to link particle physicochemical properties and bioreactivity with a wider range of the samples collected between 1955 and 74 and how such historic samples compare with present-day London ambient particles.

    Objectives The epidemiological evidence for adverse health effects of long-term exposure to air and noise pollution from traffic is not coherent. Further, the relative roles of background versus near traffic pollution concentrations in this process are unclear. We investigated relationships between modelled concentrations of air and noise pollution from traffic and incident cardiorespiratory disease in London. Methods Among 211 016 adults aged 40–79 years registered in 75 Greater London practices between 2005 and 2011, the first diagnosis for a range of cardiovascular and respiratory outcomes were identified from primary care and hospital records. Annual baseline concentrations for nitrogen oxide (NOx), particulate matter with a median aerodynamic diameter <2.5 μm (PM2.5) attributable to exhaust and non-exhaust sources, traffic intensity and noise were estimated at 20 m2 resolution from dispersion models, linked to clinical data via residential postcode. HRs were adjusted for confounders including smoking and area deprivation. Results The largest observed associations were between traffic-related air pollution and heart failure (HR=1.10 for 20 μg/m3 change in NOx, 95% CI 1.01 to 1.21). However, no other outcomes were consistently associated with any of the pollution indicators, including noise. The greater variations in modelled air pollution from traffic between practices, versus within, hampered meaningful fine spatial scale analyses. Conclusions The associations observed with heart failure may suggest exacerbatory effects rather than underlying chronic disease. However, the overall failure to observe wider associations with traffic pollution may reflect that exposure estimates based on residence inadequately represent the relevant pattern of personal exposure, and future studies must address this issue.

    Since 2003/2004, the United Kingdom has implemented a salt reduction campaign; however, there are no data on salt intake in children as assessed by 24-hour urinary sodium, the gold standard method, to inform this campaign. We performed a cross-sectional study, involving South London school children across 3 age tiers: young children (5- to 6-year olds), intermediate-aged children (8- to 9-year olds), and adolescents (13- to 17-year olds). Dietary salt intake was measured by 24-hour urinary sodium excretion and compared with newly derived maximum salt intake recommendations. In addition, dietary sources of salt were assessed using a 24-hour photographic food diary. Valid urine collections were provided by 340 children (162 girls, 178 boys). The mean salt intakes were 3.75 g/d (95% confidence interval, 3.49-4.01), 4.72 g/d (4.33-5.11), and 7.55 g/d (6.88-8.22) for the 5- to 6-year olds, 8- to 9-year olds, and 13- to 17-year olds, respectively. Sixty-six percent of the 5- to 6-year olds, 73% of the 8- to 9-year olds, and 73% of 13- to 17-year olds had salt intake above their maximum daily intake recommendations. The major sources of dietary salt intake were cereal and cereal-based products (36%, which included bread 15%), meat products (19%), and milk and milk products (11%). This study demonstrates that salt intake in children in South London is high, with most of the salt coming from processed foods. Much further effort is required to reduce the salt content of manufactured foods.

    BACKGROUND: Sexual violence against women is common. The prevalence appears to be higher in north America than Europe. However, not all surveys have differentiated the experience of forced sex by a current or former partner. Few women are thought to report these experiences to their general practitioner (GP). AIM: To measure the prevalence of rape, sexual assault, and forced sexual intercourse by a partner among women attending general practices, to test the association between these experiences of sexual violence and demographic factors, and to assess the acceptability to women of screening for sexual violence by GPs. DESIGN OF STUDY: Cross-sectional survey. METHOD: A self-administered questionnaire survey of 1207 women aged over 15 years was carried out in 13 general practices in Hackney, east London. RESULTS: Eight per cent (95% confidence interval [CI] = 6.2 to 9.6) of women have experienced rape, 9% (95% CI = 7.0 to 10.6) another type of sexual assault, and 16% (95% CI = 13.6 to 18.1) forced sex by a partner in adulthood: 24% (95% CI = 21.2 to 26.5) have experienced one or more of these types of sexual violence. Experiences of sexual violence demonstrated high levels of lifetime co-occurrence. Women forced to have sex by partners experienced the most severe forms of domestic violence. One in five women would object to routine questioning about being raped and/or sexually assaulted, and one in nine about being forced to have sex by a partner. CONCLUSION: Experiences of sexual violence are common in the lives of adult women in east London, and they represent a significant public health problem. Those women who have one experience appear to be at risk of being victims again. A substantial minority object to routine questions about sexual violence. PMID:14702905

    Modelling studies suggest that urban cycling is associated with an increased inhaled dose of fossil fuel-derived black carbon (BC). Using the amount of black material in airway macrophages as a marker of long-term inhaled BC, we sought to compare inhaled BC dose in London (UK) cyclists and non-cyclists. Airway macrophage carbon was assessed in 28 (58%) out of 48 healthy adults (14 cyclists and 14 non-cyclists) who attended for induced sputum. Short-term (24 h) exposure to BC was assessed on a representative working day in 27 out of 28 subjects. Serum interleukin (IL)-1β, IL-2, IL-6, IL-8, granulocyte-macrophage colony-stimulating factor and tumour necrosis factor (TNF)-α were assessed in 26 out of the 28 subjects. Cyclists were found to have increased airway macrophage carbon when compared with non-cyclists (mean ± se 1.81 ± 0.21 versus 1.11 ± 0.07 μm(2); p<0.01). Short-term monitoring showed no difference in 24 h BC exposure between the two groups. However, cyclists were exposed to higher concentrations of BC during commuting (p<0.01). Airway macrophage carbon was associated with monitored commute BC (n=28; r=0.47, p<0.05). TNF-α was found to be increased in cyclists (p<0.05), but no other cytokines were increased. Commuting to work by bicycle in London is associated with increased long-term inhaled dose of BC. Whether cycling per se increases inhaled BC dose remains unclear.

    Water supply planning in many major world cities faces several challenges associated with but not limited to climate change, population growth and insufficient land availability for infrastructure development. Long-term plans to maintain supply-demand balance and ecosystem services require careful consideration of uncertainties associated with future conditions. The current approach for London's water supply planning utilizes least cost optimization of future intervention schedules with limited uncertainty consideration. Recently, the focus of the long-term plans has shifted from solely least cost performance to robustness and resilience of the system. Identifying robust scheduling of interventions requires optimizing over a statistically representative sample of stochastic inputs which may be computationally difficult to achieve. In this study we optimize schedules using an ensemble of plausible scenarios and assess how manipulating that ensemble influences the different Pareto-approximate intervention schedules. We investigate how a major stress event's location in time as well as the optimization problem formulation influence the Pareto-approximate schedules. A bootstrapping method that respects the non-stationary trend of climate change scenarios and ensures the even distribution of the major stress event in the scenario ensemble is proposed. Different bootstrapped hydrological scenario ensembles are assessed using many-objective scenario optimization of London's future water supply and demand intervention scheduling. However, such a "fixed" scheduling of interventions approach does not aim to embed flexibility or adapt effectively as the future unfolds. Alternatively, making decisions based on the observations of occurred conditions could help planners who prefer adaptive planning. We will show how rules to guide the implementation of interventions based on observations may result in more flexible strategies.

    Large outbreaks of tuberculosis (TB) represent a particular threat to disease control because they reflect multiple instances of active transmission. The extent to which long chains of transmission contribute to high TB incidence in London is unknown. We aimed to estimate the contribution of large clusters to the burden of TB in London and identify risk factors. We identified TB patients resident in London notified between 2010 and 2014, and used 24-locus mycobacterial interspersed repetitive units-variable number tandem repeat strain typing data to classify cases according to molecular cluster size. We used spatial scan statistics to test for spatial clustering and analysed risk factors through multinomial logistic regression. TB isolates from 7458 patients were included in the analysis. There were 20 large molecular clusters (with n>20 cases), comprising 795 (11%) of all cases; 18 (90%) large clusters exhibited significant spatial clustering. Cases in large clusters were more likely to be UK born (adjusted odds ratio 2.93, 95% CI 2.28-3.77), of black-Caribbean ethnicity (adjusted odds ratio 3.64, 95% CI 2.23-5.94) and have multiple social risk factors (adjusted odds ratio 3.75, 95% CI 1.96-7.16). Large clusters of cases contribute substantially to the burden of TB in London. Targeting interventions such as screening in deprived areas and social risk groups, including those of black ethnicities and born in the UK, should be a priority for reducing transmission.

    Eighteenth-century gardens have traditionally been viewed as spaces designed for leisure, and as representations of political status, power and taste. In contrast, this paper will explore the concept that gardens in this period could be seen as dynamic spaces where scientific experiment and medical practice could occur. Two examples have been explored in the pilot study which has led to this paper - the designed landscapes associated with John Hunter's Earl's Court residence, in London, and the garden at Edward Jenner's house in Berkeley, Gloucestershire. Garden history methodologies have been implemented in order to consider the extent to which these domestic gardens can be viewed as experimental spaces.

    2012-01-01

    This study sets out to extend and challenge existing historiography on late eighteenth century British popular culture, customary sports, class and cultural identity, focusing upon the rural geo-political borderland of England. It suggests that prevailing class-based and more London-biased studies need to be balanced with more regionalist-based work, and shows the importance of northern regional leisure variants. The textual and historical analysis draws largely on the published works of a neglected working-class dialect poet, Robert Anderson, living and working in Cumberland, arguing that he represented a strain of ''bardic regionalism,'' a variant of Katie Trumpener’s ''bardic nationalism.''

    Road traffic gives rise to noise and air pollution exposures, both of which are associated with adverse health effects especially for cardiovascular disease, but mechanisms may differ. Understanding the variability in correlations between these pollutants is essential to understand better their separate and joint effects on human health. We explored associations between modelled noise and air pollutants using different spatial units and area characteristics in London in 2003-2010. We modelled annual average exposures to road traffic noise (LAeq,24h, Lden, LAeq,16h, Lnight) for ~190,000 postcode centroids in London using the UK Calculation of Road Traffic Noise (CRTN) method. We used a dispersion model (KCLurban) to model nitrogen dioxide, nitrogen oxide, ozone, total and the traffic-only component of particulate matter ≤2.5μm and ≤10μm. We analysed noise and air pollution correlations at the postcode level (~50 people), postcodes stratified by London Boroughs (~240,000 people), neighbourhoods (Lower layer Super Output Areas) (~1600 people), 1km grid squares, air pollution tertiles, 50m, 100m and 200m in distance from major roads and by deprivation tertiles. Across all London postcodes, we observed overall moderate correlations between modelled noise and air pollution that were stable over time (Spearman's rho range: |0.34-0.55|). Correlations, however, varied considerably depending on the spatial unit: largest ranges were seen in neighbourhoods and 1km grid squares (both Spearman's rho range: |0.01-0.87|) and was less for Boroughs (Spearman's rho range: |0.21-0.78|). There was little difference in correlations between exposure tertiles, distance from road or deprivation tertiles. Associations between noise and air pollution at the relevant geographical unit of analysis need to be carefully considered in any epidemiological analysis, in particular in complex urban areas. Low correlations near roads, however, suggest that independent effects of road noise and

    In 1811, François Arago observed the disk of the Sun with his "lunette polariscopique". From the absence of detectable polarization compared with his laboratory observations of glowing solids, liquids, and flames he concluded that the Sun's visible surface is an incandescent gas. From this beginning, thanks to orders of magnitude technology improvements, a remarkable amount of what we know about the physics of the Sun has continued to flow from solar polarimetry. This short review compares some selected polarimetric discoveries with subsequent recent observations to illustrate the tremendous progress of solar polarimetry during the last two centuries.

  7. Wintertime aerosol chemical composition, volatility, and spatial variability in the greater London area

    The composition of PM1 (particulate matter with diameter less than 1 µm) in the greater London area was characterized during the Clean Air for London (ClearfLo) project in winter 2012. Two high-resolution time-of-flight aerosol mass spectrometers (HR-ToF-AMS) were deployed at a rural site (Detling, Kent) and an urban site (North Kensington, London). The simultaneous and high-temporal resolution measurements at the two sites provide a unique opportunity to investigate the spatial distribution of PM1. We find that the organic aerosol (OA) concentration is comparable between the rural and urban sites, but the contribution from different sources is distinctly different between the two sites.more » The concentration of solid fuel OA at the urban site is about twice as high as at the rural site, due to elevated domestic heating in the urban area. While the concentrations of oxygenated OA (OOA) are well-correlated between the two sites, the OOA concentration at the rural site is almost twice that of the urban site. At the rural site, more than 70 % of the carbon in OOA is estimated to be non-fossil, which suggests that OOA is likely related to aged biomass burning considering the small amount of biogenic SOA in winter. Thus, it is possible that the biomass burning OA contributes a larger fraction of ambient OA in wintertime than what previous field studies have suggested. A suite of instruments was deployed downstream of a thermal denuder (TD) to investigate the volatility of PM1 species at the rural Detling site. After heating at 250 °C in the TD, 40 % of the residual mass is OA, indicating the presence of non-volatile organics in the aerosol. Although the OA associated with refractory black carbon (rBC; measured by a soot-particle aerosol mass spectrometer) only accounts for < 10 % of the total OA (measured by a HR-ToF-AMS) at 250 °C, the two measurements are well-correlated, suggesting that the non-volatile organics have similar sources or have

    In parts of London, faulting introduces lateral heterogeneity to the local ground conditions, especially where construction works intercept the Palaeogene Lambeth Group. This brings difficulties to the compilation of a ground model that is fully consistent with the ground investigation data, and so to the design and construction of engineering works. However, because bedrock in the London area is rather uniform at outcrop, and is widely covered by Quaternary deposits, few faults are shown on the geological maps of the area. This paper discusses a successful resolution of this problem at a site in east central London, where tunnels for a new underground railway station are planned. A 3D geological model was used to provide an understanding of the local geological structure, in faulted Lambeth Group strata, that had not been possible by other commonly-used methods. This model includes seven previously unrecognised faults, with downthrows ranging from about 1 m to about 12 m. The model was constructed in the GSI3D geological modelling software using about 145 borehole records, including many legacy records, in an area of 850 m by 500 m. The basis of a GSI3D 3D geological model is a network of 2D cross-sections drawn by a geologist, generally connecting borehole positions (where the borehole records define the level of the geological units that are present), and outcrop and subcrop lines for those units (where shown by a geological map). When the lines tracing the base of each geological unit within the intersecting cross-sections are complete and mutually consistent, the software is used to generate TIN surfaces between those lines, so creating a 3D geological model. Even where a geological model is constructed as if no faults were present, changes in apparent dip between two data points within a single cross-section can indicate that a fault is present in that segment of the cross-section. If displacements of similar size with the same polarity are found in a series

    In order to investigate a specific area of short-term, non-occupational, human exposure to fine particulate air pollution, measurements of personal exposure to PM2.5 in transport microenvironments were taken in two separate field studies in central London, UK. A high flow gravimetric personal sampling system was used; operating at 16 l min(-1); the sampler thus allowed for sufficient sample mass collection for accurate gravimetric analysis of short-term travel exposure levels over typical single commute times. In total, samples were taken on 465 journeys and 61 volunteers participated. In a multi-transport mode study, carried out over 3-week periods in the winter and in the summer, exposure levels were assessed along three fixed routes at peak and off-peak times of the day. Geometric means of personal exposure levels were 34.5 microg m(-3) (G.S.D.= 1.7, n(s) = 40), 39.0 microg m(-3) (G.S.D. = 1.8, n(s) = 36), 37.7 microg m(-3) (G.S.D. = 1.5, n(s) = 42), and 247.2 microg m(-3) (G.S.D. = 1.3, n(s) = 44) for bicycle, bus, car and Tube (underground rail system) modes, respectively, in the July 1999 (summer) measurement campaign. Corresponding levels in the February 2000 (winter) measurement campaign were 23.5 microg m(-3) (G.S.D. = 1.8, n(s) = 56), 38.9 microg m(-3) (G.S.D. = 2.1, n(s) = 32), 33.7 microg m(-3) (G.S.D. = 2.4, n(s) = 12), and 157.3 microg m(-3) (G.S.D. = 3.3, n(s) = 12), respectively. In a second study, exposure levels were measured for a group of 24 commuters travelling by bicycle, during August 1999, in order to assess how representative the fixed route studies were to a larger commuter population. The geometric mean exposure level was 34.2 microg m(-3) (G.S.D. = 1.9, n(s) = 105). In the fixed-route study, the cyclists had the lowest exposure levels, bus and car were slightly higher, while mean exposure levels on the London Underground rail system were 3-8 times higher than the surface transport modes. There was significant between-route variation

    The composition of PM1 (particulate matter with diameter less than 1 µm) in the greater London area was characterized during the Clean Air for London (ClearfLo) project in winter 2012. Two high-resolution time-of-flight aerosol mass spectrometers (HR-ToF-AMS) were deployed at a rural site (Detling, Kent) and an urban site (North Kensington, London). The simultaneous and high-temporal resolution measurements at the two sites provide a unique opportunity to investigate the spatial distribution of PM1. We find that the organic aerosol (OA) concentration is comparable between the rural and urban sites, but the contribution from different sources is distinctly different between the two sites. The concentration of solid fuel OA at the urban site is about twice as high as at the rural site, due to elevated domestic heating in the urban area. While the concentrations of oxygenated OA (OOA) are well-correlated between the two sites, the OOA concentration at the rural site is almost twice that of the urban site. At the rural site, more than 70 % of the carbon in OOA is estimated to be non-fossil, which suggests that OOA is likely related to aged biomass burning considering the small amount of biogenic SOA in winter.

    There is growing global consumption of non-fossil fuels such as ethanol made from renewable biomass. Previous studies have shown that one of the main air quality disadvantages of using ethanol blended fuels is a significant increase in the production of acetaldehyde, an unregulated and toxic pollutant. Most studies on the impacts of ethanol blended gasoline have been carried out in the US and Brazil, with much less focus on the UK and Europe. We report time resolved measurements of ethanol in London during the winter and summer of 2012. In both seasons the mean mixing ratio of ethanol was around 5 ppb, with maximum values over 30 ppb, making ethanol currently the most abundant VOC in London air. We identify a road transport related source, with 'rush-hour' peaks observed. Ethanol is strongly correlated with other road transport-related emissions, such as small aromatics and light alkanes, and has no relationship to summer biogenic emissions. To determine the impact of road transport-related ethanol emission on secondary species (i.e. acetaldehyde and ozone), we use both a chemically detailed box model (incorporating the Master Chemical Mechanism, MCM) and a global and nested regional scale chemical transport model (GEOS-Chem), on various processing time scales. Using the MCM model, only 16% of the modelled acetaldehyde was formed from ethanol oxidation. However, the model significantly underpredicts the total levels of acetaldehyde, indicating a missing primary emission source, that appears to be traffic-related. Further support for a primary emission source comes from the regional scale model simulations, where the observed concentrations of ethanol and acetaldehyde can only be reconciled with the inclusion of large primary emissions. Although only constrained by one set of observations, the regional modelling suggests a European ethanol source similar in magnitude to that of ethane (∼60 Gg per year) and greater than that of acetaldehyde (∼10 Gg per year).

    Trace element measurements in PM10-2.5, PM2.5-1.0 and PM1.0-0.3 aerosol were performed with 2 h time resolution at kerbside, urban background and rural sites during the ClearfLo winter 2012 campaign in London. The environment-dependent variability of emissions was characterized using the Multilinear Engine implementation of the positive matrix factorization model, conducted on data sets comprising all three sites but segregated by size. Combining the sites enabled separation of sources with high temporal covariance but significant spatial variability. Separation of sizes improved source resolution by preventing sources occurring in only a single size fraction from having too small a contribution for the model to resolve. Anchor profiles were retrieved internally by analysing data subsets, and these profiles were used in the analyses of the complete data sets of all sites for enhanced source apportionment. A total of nine different factors were resolved (notable elements in brackets): in PM10-2.5, brake wear (Cu, Zr, Sb, Ba), other traffic-related (Fe), resuspended dust (Si, Ca), sea/road salt (Cl), aged sea salt (Na, Mg) and industrial (Cr, Ni); in PM2.5-1.0, brake wear, other traffic-related, resuspended dust, sea/road salt, aged sea salt and S-rich (S); and in PM1.0-0.3, traffic-related (Fe, Cu, Zr, Sb, Ba), resuspended dust, sea/road salt, aged sea salt, reacted Cl (Cl), S-rich and solid fuel (K, Pb). Human activities enhance the kerb-to-rural concentration gradients of coarse aged sea salt, typically considered to have a natural source, by 1.7-2.2. These site-dependent concentration differences reflect the effect of local resuspension processes in London. The anthropogenically influenced factors traffic (brake wear and other traffic-related processes), dust and sea/road salt provide further kerb-to-rural concentration enhancements by direct source emissions by a factor of 3.5-12.7. The traffic and dust factors are mainly emitted in PM10-2.5 and show strong

    During the month of October 2006, as part of the REPARTEE-I experiment (Regent's Park and Tower Environmental Experiment) an Aerosol Time-Of-Flight Mass Spectrometer (ATOFMS) was deployed at an urban background location in the city of London, UK. Fifteen particle types were classified, some of which were already discussed (Dall'Osto et al., 2009a,b; Harrison et al., 2012). In this manuscript the origins and properties of four unreported particle types postulated to be due to locally generated aerosols, independent of the air mass type advected into London, are examined. One particle type, originating from lubricating oil (referred to as Ca-EC), was associated with morning rush hour traffic emissions. A second particle type, composed of both inorganic and organic species (called Na-EC-OC), was found enhanced in particle number concentration during evening time periods, and is likely to originate from a source operating at this time of day, or more probably from condensation of semi-volatile species. A third class, internally mixed with organic carbon and sulphate (called OC), was found to spike both in the morning and evenings although it could not unambiguously associated with a specific source or atmospheric process. The fourth class (Secondary Organic Aerosols - Polycyclic Aromatic Hydrocarbon; SOA-PAH) exhibited maximum frequency during the warmest part of the day, and a number of factors point towards secondary aerosol production from traffic-related volatile aromatic compounds. Single particle mass spectra of this particle type showed an oxidized polycyclic aromatic compound signature. A comparison of ATOFMS particle class data is then made with factors obtained by Positive Matrix Factorization and PAH signatures obtained from Aerosol Mass Spectrometer (AMS) data (Allan et al., 2010). Both the Ca-EC and OC particle types correlate with primary Hydrocarbon-like Organic Aerosol (HOA, R2 = 0.65 and 0.50 respectively), and Na-EC-OC correlates weakly with the AMS

    Atmospheric composition within urban areas has a direct effect on the air quality of an environment in which a large majority of people live and work. Atmospheric pollutants including ozone (O3), nitrogen dioxide (NO2), volatile organic compounds (VOCs) and particulate matter (PM) can have a significant effect on human health. As such it is important to determine the potential exposure of individuals to these atmospheric constituents and investigate the processes that lead to the degradation of air quality within the urban environment. Whilst modelled pollutant levels on the local scale often suggest high degrees of spatial and temporal variability, the relatively sparse fixed site automated urban networks only provide low spatial resolution data that do not appear adequate in detecting such small scale variability. In this paper we demonstrate that measurements can now be made using networks of low-cost sensors that utilise a variety of techniques, including electrochemical and optical, to measure concentrations of atmospheric species. Once equipped with GPS and GPRS to determine position and transmit data respectively, these networks have the potential to provide valuable insights into pollutant variability inherent on the local or micro-scale. The methodology has been demonstrated successfully in field campaigns carried out in cities including London and Valencia, and is now being deployed as part of the Sensor Networks for Air Quality currently deployed at London Heathrow airport (SNAQ-Heathrow) which is outlined in the partner paper presented by Mead et al. (this conference). The SNAQ-Heathrow network of 50 sensor nodes will provide an unprecedented data set that includes measurements of O3, NO, NO2, CO, CO2, SO2, total VOCs, size-speciated PM as well as meteorological variables that include temperature, relative humidity, wind speed and direction. This network will provide high temporal (20 second intervals) and spatial (50 sites within the airport area

    In the early modern period, saltpetre was perhaps best known for its role as one of the three components of gunpowder. For natural philosophers in seventeenth-century England, saltpetre also had important uses in chymistry and medicine. While some factories did successfully produce saltpetre in early modern England, the domestic industry was not on the whole a great success. Intellectuals who were keen to apply their knowledge in the real world saw this as an opportunity, and proposed a variety of new and improved methods that they claimed would produce this vital material more efficiently and in abundance. Yet their proposals remained on the page and their efforts fell flat. To understand the challenges and experiences faced by both scholars and artisan saltpetre-makers, I 'reworked' early modern methods of saltpetre-making with the Medieval Gunpowder Research Group. Reworking revealed procedural challenges and complexities that explain why, even with the best intentions, seventeenth-century natural philosophers struggled to get to grips with this important material.

    Urine has always interested and attracted the attention of people. It was in fact never considered a waste product of the body but rather as a distilled product selected from the blood and containing useful substances for the care of the body. It was referred to as the "gold of the blood" and "elixir of long life," indicating its therapeutic potential. This paper reports on the practice of urine therapy since its origin attributed to the Indian culture, and briefly reviews its use through the centuries and different cultures and traditions. Records from the Egyptians to Jews, Greeks, Romans and from the Middle Ages and the Renaissance testify to the practice of urine therapy--a practice that continues to be found in more recent times, from the 18th century to the present. Experiences with the practice of urine therapy have even been discussed and shared recently in 2 different conferences: in 1996 in India and in 1999 in Germany, where people from different countries shared and presented their own research on urine therapy.

    Mobility and migration patterns of groups and individuals have long been a topic of interest to archaeologists, used for broad explanatory models of cultural change as well as illustrations of historical particularism. The 14th century AD was a tumultuous period of history in Britain, with severely erratic weather patterns, the Great Famine of 1315-1322, the Scottish Wars of Independence, and the Hundred Years' War providing additional migration pressures to the ordinary economic issues drawing individuals to their capital under more stable conditions. East Smithfield Black Death Cemetery (Royal Mint) had a documented use period of only 2 years (AD 1348-1350), providing a precise historical context (∼50 years) for data. Adults (n = 30) from the East Smithfield site were sampled for strontium and oxygen stable isotope analyses of tooth enamel. Five individuals were demonstrated to be statistical outliers through the combined strontium and oxygen isotope data. Potential origins for migrants ranged from London's surrounding hinterlands to distant portions of northern and western Britain. Historic food sourcing practices for London were found to be an important factor for consideration in a broader than expected (87) Sr/(86) Sr range reflected in a comparison of enamel samples from three London datasets. The pooled dataset demonstrated a high level of consistency between site data, divergent from the geologically predicted range. We argue that this supports the premise that isotope data in human populations must be approached as a complex interaction between behavior and environment and thus should be interpreted cautiously with the aid of alternate lines of evidence.

    Human immunodeficiency virus (HIV) prevention delivered in gay venues in US cities has been found to be effective in reducing HIV transmission in the 1990s but effects might not be generalizable to different times and settings. Doubts have been raised about: outreach's ability to address skills and explore personal behaviour; big-city commercial gay venues being appropriate sites for outreach because of gossip and social surveillance; and acceptability of outreach by professionals rather than 'popular opinion formers'. We evaluated coverage, feasibility, acceptability and perceived impact of venue-based HIV prevention outreach by professionals in London, employing observation, surveys and interviews with venue-users, and focus groups/semi-structured interviews with workers. We found high coverage especially among target groups. Addressing negotiation skills and personal behaviour was feasible but required worker motivation and skill. Social surveillance rarely impeded work. Gay men generally found outreach acceptable and useful, and professionals were not regarded negatively. Impact on knowledge was commonly reported; impacts on negotiation skills and reflection on personal behaviour were more common among men experiencing longer contacts. In conclusion, professional HIV prevention outreach in gay venues in large cities is a feasible and acceptable intervention with significant potential impacts. Workers need to be well briefed and trained to maximize impact.

    Around 150 cities have emerged as notable at a global scale. With a global population of fewer than 12%, they generate 46% of world gross domestic product. There is growing interest in how cities can accelerate health improvements through wider social and economic collaboration. A team led by Public Health England in London visited counterparts in New York City and Paris to examine how city health leaders addressed public health challenges. The three cities have similar health challenges but different legal, political and fiscal resources for promoting and protecting health. Consequently, there is no single model that every city could adopt. Organizational structures, interpersonal relationships and individual skills can play an important part in effective delivery of better city health. Lack of access to published evidence on how practice has been influenced by city health policies hampers learning between cities. There is little easily comparable data to guide those interested in such learning. Municipal governments are ideally situated to join researchers to fill this gap in the literature.

    The lethal poisoning of Alexander Litvinenco with the radioactive element polonium-210, and the risk that many civilians (including Israeli citizens) who were in the same location in London at the same time were exposed to radiation, was an unprecedented event in the western world. This was only the second known death due to 210Po, a natural alpha radiation-emitting element. A task team was created to handle the event. The team comprised representatives from the Ministry of Health's advisory committee for radiological events (which includes the Israel Defense Force, the Israeli Atomic Energy Commission and the Ministry of Environmental Protection), the Public Health Services Central District, and a public relations expert. Forty-seven people were located and underwent an epidemiological inquiry, and urine samples for detection of 210Po were sent abroad to a specialized laboratory. The radiotoxicological results were analyzed and evaluated by the expert team and follow-up recommendations were made. This unfamiliar and potentially stressful scenario was handled successfully by a multi-organizational multidisciplinary task team. The joint work of the task team was a real-life "exercise" simulating a radiological event in Israel. This team has recommended further evaluation of various vital missions in the event of any possible future radiological event, with special emphasis on a proactive communication approach to the media and the public.

    STUDY OBJECTIVE: To provide those working at district level with practical guidance on using hospital data linked to small geographic areas to explore patterns of care. DESIGN: Examination of the association between age standardised hospital episode rates for the commonest diagnostic categories and deprivation levels (Carstairs index) of the electoral ward of residence. SETTING: An inner London district, Kensington, Chelsea and Westminster, with a population of approximately 325,000. POPULATION: All finished consultant episodes recorded in NHS hospitals for the district population in the year to April 1994. MAIN RESULTS: Many, but not all, disease categories were associated strongly with deprivation, with high episode rates in the most deprived electoral wards. This is partly due to more of those in deprived areas being admitted to hospital and to them being admitted more often. CONCLUSIONS: A wide range of factors needs to be taken into account in interpreting these data. They include the contribution of the private sector and artifacts of both the numerator and denominator. This paper provides a framework for those working at district level to begin to analyse the association between hospitalisation and deprivation locally. It also identifies some of the issues that must be taken into account when seeking to interpret these data. PMID:8935471

    Asthma is a chronic condition of great public health concern globally. The associated morbidity, mortality and healthcare utilisation place an enormous burden on healthcare infrastructure and services. This study demonstrates a multistage quantile regression approach to predicting excess demand for health care services in the form of asthma daily admissions in London, using retrospective data from the Hospital Episode Statistics, weather and air quality. Trivariate quantile regression models (QRM) of asthma daily admissions were fitted to a 14-day range of lags of environmental factors, accounting for seasonality in a hold-in sample of the data. Representative lags were pooled to form multivariate predictive models, selected through a systematic backward stepwise reduction approach. Models were cross-validated using a hold-out sample of the data, and their respective root mean square error measures, sensitivity, specificity and predictive values compared. Two of the predictive models were able to detect extreme number of daily asthma admissions at sensitivity levels of 76 % and 62 %, as well as specificities of 66 % and 76 %. Their positive predictive values were slightly higher for the hold-out sample (29 % and 28 %) than for the hold-in model development sample (16 % and 18 %). QRMs can be used in multistage to select suitable variables to forecast extreme asthma events. The associations between asthma and environmental factors, including temperature, ozone and carbon monoxide can be exploited in predicting future events using QRMs.

    Preparing a national team for success at major sporting competitions such as the Olympic Games has become a systematic and multi-faceted activity. Sports nutrition contributes to this success via strategic nutritional interventions that optimize the outcomes from both the training process and the competitive event. This review summarizes the National Nutrition Programs involved with the 2012 London Olympic Games preparation of the Australian, British and American sports systems from the viewpoints of three key agencies: the Australian Institute of Sport, the English Institute of Sport and the United States Olympic Committee. Aspects include development of a nutrition network involving appropriately qualified sports dietitians/nutritionists within a multi-disciplinary team, recognition of continual updates in sports nutrition knowledge, and a systematic approach to service delivery, education and research within the athlete's daily training environment. Issues of clinical nutrition support must often be integrated into the performance nutrition matrix. Food service plays an important role in the achievement of nutrition goals during the Olympic Games, both through the efforts of the Athlete Dining Hall and catering activities of the host Olympic Games Organizing Committees as well as adjunct facilities often provided by National Olympic Committees for their own athletes.

    The notion of community has been central to the political project of renewal of New Labour in the UK. The paper explores how the discourses of community are framed within New Labour and discusses these in the light of the results from research which focuses on how people within urban deprived areas construct their community. It draws upon the results of one part of a larger research project (the ‘Well London’ programme) which aimed to capture the views of residents from 20 disadvantaged neighbourhoods throughout London using an innovative qualitative method known as the ‘World Café’. Our results show the centrality of young people to the development of cohesive communities, the importance of building informal relationships between residents alongside encouraging greater participation to policy making, and the need to see these places as fragile and temporary locations but with considerable social strengths. Government policies are only partially addressing these issues. They pay greater attention to formally encouraging citizens to become more involved in policy making, largely ignore the contribution young people could make to the community cohesion agenda, and weakly define the shared norms and values that are crucial in building cohesive communities. Thus, the conclusion is that whilst an emphasis of the government on ‘community’ is to be welcome, more needs to be done in terms of considering the ‘voices’ of the community as well as enabling communities to determine and act upon their priorities.

    Sex work, and ideas about women in the trade, have long been represented as tragic and/or threatening. However, such portrayals tell us very little about how women think about themselves and the kinds of work they do. The data for this paper come from an ethnographic, community-based study in London, Ontario, that involves women in street-based, indoor and transactional sex work. This discussion focuses on how women develop different individual identities, including the management of multiple selves, their sexual identities and what we have termed the 'good junkie' identity. We also examine how these women employ aspects of dominant representation of sex workers, namely the low status accorded to those in street-based work and the defamatory term 'whore' or 'ho', when negotiating the moral hierarchies that exist within various kinds of sex work (i.e., stripping, massage parlours) and making sense of their professional and personal lives. The work that goes into the creation and maintenance of the women's divergent identities sheds important light on this complicated and tremendously demanding, yet inadequately understood, aspect of life as women in the sex trade.

    On 22 March 2013, 150 of 1,255 students (13–17 years) and staff at a school in London reported gastrointestinal symptoms; onset peaked 8 to 12 hours after a lunch served in the school on 21 March. We performed a retrospective cohort study of all students and staff. We defined cases as school attenders on 20 and 21 March with onset of gastrointestinal symptoms between 20 and 23 March. We tested food, environmental and stool samples of cases for common pathogens and bacterial toxins. We administered an online questionnaire via email, encouraging the use of smartphones to respond, to measure risk of illness for food items eaten at school on 20 and 21 March. Survey response was 45%. Adjusted risk ratios were generated in a multivariable analysis. Those who ate chicken balti on 21 March were 19.3 times more likely to become ill (95% confidence interval: 7.3–50.9). Clostridium perfringens was detected in all 19 stool samples collected. Within eight school hours of its launch, 412 of 561 (73%) responders had completed the survey. Hygienic standards in the kitchen were satisfactory. The investigation was done rapidly due to smartphone technology and we recommend considering this technology in future outbreaks.

    a survey of respiratory disease among male physicians of London, Ontario, resulted in a 96.3% response. The age-standardized rates of chronic bronchitis were not very different from others reported in the recent medical literature, taking into account smoking habits, but the overall prevalence of bronchial asthma was high (7.4%), with a low prevalence in the category “obstructive lung disease”. The possibility of overlap or interchange in these diagnoses is raised, although the diagnosis of bronchial asthma in this particular group is believed to be well established in every case. A history of seasonal hay fever was given by 19.4%. One of 88 (1%) non-smokers had bronchitis, whereas six of them (7%) had asthma. Rhonchi heard in the chest, on a single examination, appeared to be most closely related to current smoking habits, ventilatory function tests and also to a clinical diagnosis of chronic bronchitis or obstructive lung disease, but not to bronchial asthma.

    Cities are important sources of carbon dioxide (CO2) and methane (CH4). Anthropogenic CO2 is released in the combustion of fossil fuels for heating, electricity and transport. The major sources of CH4 in city environments are natural gas leakage, landfill sites and transport emissions. Monitoring of urban greenhouse gas concentrations is crucial for cities aiming to reduce emissions through measures such as changes to the transport infrastructure and green planning. We present measurements of CO2 and CH4 concentrations using Cavity Ring-Down Spectroscopy (CRDS) at four sites located in and around London, UK. Two sites were located in the inner city, one in the suburban fringe and the fourth in a rural location close to the city. This study was funded by Astrium Services Ltd as part of a pilot scheme to monitor city-scale GHG emissions and presented a unique opportunity to study changes in greenhouse gas concentrations across an urban to rural 'transect'. The CHIMERE chemistry-transport model is used to estimate CO2 and CH4 concentrations throughout the four month measurement period during the summer of 2012. Comparisons are made between the measured and modelled CO2 and CH4 concentrations and the representativity of the study sites for future urban greenhouse gas monitoring is considered. This study also examines the ability of a variety of measurement and modelling techniques to partition anthropogenic and biogenic CO2 sources.

    Improving access to National Health Service (NHS) dentistry is a public health issue that has been a focus for successive governments and policy makers in the UK. To inform this process, commissioners of services need to understand trends in service use and demands of the local population. This study explored inequalities in dental services use among adults in a socially deprived, ethnically diverse metropolitan area of London; satisfaction with services; and public views for improvement of services. Data from 695 adults were analysed for this study (56% of the eligible sample). Inequalities in dental services use and satisfaction with care according to sociodemographic factors were assessed in unadjusted and fully adjusted models. The proportion of participants who reported attending the dentist in the last 24 months was 69%, with inequalities according to social grade, ethnicity, sex and age but not according to borough of residence. The most common areas identified by respondents for service improvement were availability of dentists, affordability of care, and accommodation of services. Among those who visited the dentist in the last 24 months, 90% were satisfied with the quality of care provided. However, there were inequalities in satisfaction with care according to borough and reason for the last dental visit.

  11. Evaluating clustering methods within the Artificial Ecosystem Algorithm and their application to bike redistribution in London.

    This paper proposes and evaluates a solution to the truck redistribution problem prominent in London's Santander Cycle scheme. Due to the complexity of this NP-hard combinatorial optimisation problem, no efficient optimisation techniques are known to solve the problem exactly. This motivates our use of the heuristic Artificial Ecosystem Algorithm (AEA) to find good solutions in a reasonable amount of time. The AEA is designed to take advantage of highly distributed computer architectures and adapt to changing problems. In the AEA a problem is first decomposed into its relative sub-components; they then evolve solution building blocks that fit together to form a single optimal solution. Three variants of the AEA centred on evaluating clustering methods are presented: the baseline AEA, the community-based AEA which groups stations according to journey flows, and the Adaptive AEA which actively modifies clusters to cater for changes in demand. We applied these AEA variants to the redistribution problem prominent in bike share schemes (BSS). The AEA variants are empirically evaluated using historical data from Santander Cycles to validate the proposed approach and prove its potential effectiveness.

    We retrospectively analyzed the background, clinical features, and treatment response of 50 cases of imported loiasis who presented between 2000 and 2014 to the Hospital for Tropical Diseases (HTD), London, United Kingdom. Of them, 29 were migrants from, and 21 were visitors to, countries where the disease is endemic. Clinical features differed between these groups. Migrants experienced fewer Calabar swellings (odds ratio [OR] = 0.12), more eye worm (OR = 3.4), more microfilaremia (OR = 3.5), lower filarial antibody levels, and lower eosinophil counts (P < 0.05 for all tests). Among 46 patients who were started on treatment at HTD, 33 (72%) received diethylcarbamazine (DEC) monotherapy as first-line treatment, and among 26 patients who were followed up after treatment, seven (27%) needed a second course of treatment. There were 46 courses of treatment with DEC, and 20 (43%) of them had reactions. All patients with microfilaremia > 3,000 microfilariae/mL and all those with an elevated C-reactive protein (CRP) (≥ 5 mg/L) before treatment had reactions (P = 0.10 and P = 0.01, respectively). These data suggest that monotherapy with DEC may not be the optimal treatment for patients with loiasis, particularly for those with a high microfilarial load. PMID:26101271

    In this study, we link a water resource management simulator to multi-objective search to reveal the key trade-offs inherent in planning a real-world water resource system. We consider new supplies and demand management (conservation) options while seeking to elucidate the trade-offs between the best portfolios of schemes to satisfy projected water demands. Alternative system designs are evaluated using performance measures that minimize capital and operating costs and energy use while maximizing resilience, engineering and environmental metrics, subject to supply reliability constraints. Our analysis shows many-objective evolutionary optimization coupled with state-of-the art visual analytics can help planners discover more diverse water supply system designs and better understand their inherent trade-offs. The approach is used to explore future water supply options for the Thames water resource system (including London's water supply). New supply options include a new reservoir, water transfers, artificial recharge, wastewater reuse and brackish groundwater desalination. Demand management options include leakage reduction, compulsory metering and seasonal tariffs. The Thames system's Pareto approximate portfolios cluster into distinct groups of water supply options; for example implementing a pipe refurbishment program leads to higher capital costs but greater reliability. This study highlights that traditional least-cost reliability constrained design of water supply systems masks asset combinations whose benefits only become apparent when more planning objectives are considered.

    Nearshore areas within Long Island Sound are of great interest to the Connecticut and New York research and resource management communities because of their ecological, recreational, and commercial importance. Although advances in multibeam echosounder technology permit the construction of high-resolution representations of sea-floor topography in deeper waters, limitations inherent in collecting fixed-angle multibeam data make using this technology in shallower waters (less than 10 meters deep) difficult and expensive. These limitations have often resulted in data gaps between areas for which multibeam bathymetric datasets are available and the adjacent shoreline. To address this problem, the geospatial data sets released in this report seamlessly integrate complete-coverage multibeam bathymetric data acquired off New London and Niantic Bay, Connecticut, with hydrographic Light Detection and Ranging (LIDAR) data acquired along the nearshore. The result is a more continuous sea floor representation and a much smaller gap between the digital bathymetric data and the shoreline than previously available. These data sets are provided online and on CD-ROM in Environmental Systems Research Institute (ESRI) raster-grid and GeoTIFF formats in order to facilitate access, compatibility, and utility.

    In this work, we present a novel model, referred to as BH-DFT-D, for the evaluation of London dispersion, with the purpose to correct the performance of local DFT exchange-correlation functionals for the description of van der Waals interactions. The new BH-DFT-D model combines the equations originally derived by Buckingham [Buckingham, A. D. Adv. Chem. Phys1967, 12, 107] with the definition of distributed multipole polarizability tensors within the Hirshfeld method [Hirshfeld, F.L. Theor. Chim. Acta1977, 44, 129], resulting in nonlocal, fully anisotropic expressions. Since no damping function has been introduced yet into the model, it is suitable in its present form for the evaluation of dispersion interactions in van der Waals dimers with no or negligible overlap. The new method is tested for an extended collection of van der Waals dimers against high-level data, where it is found to reproduce interaction energies at the BH-B3LYP-D/aug-cc-pVTZ level with a mean average error (MAE) of 0.20 kcal/mol. Next, development steps of the model will consist of adding a damping function, analytical gradients, and generalization to a supramolecular system.

  16. Low temperature London penetration depth and superfluid density in Fe-based superconductors

    The superconducting gap symmetry of the Fe-based superconductors was studied by measurements and analysis of London penetration depth and super uid density. Tunnel diode resonator technique for these measurements was implemented in a dilution refrigerator allowing for the temperatures down to 50 mK. For the analysis of the super uid density, we used both experimental studies of Al-coated samples and original thermodynamic approach based on Rutgers relation. In three systems studied, we found that the superconducting gap at the optimal doping is best described in multi-gap full gap scenario. By performing experiments on samples with arti cially introduced disorder with heavy ion irradiation, we show that evolution of the superconducting transition temperature and of the super uid density are consistent with full-gap sign changing s superconducting state. The superconducting gap develops strong modulation both in the under-doped and the over-doped regimes. In the terminal hole-doped KFe{sub 2}As{sub 2}, both temperature dependence of the super uid density and its evolution with increase of the scattering rate are consistent with symmetry imposed vertical line nodes in the superconducting gap. By comparative studies of hole-doped (Ba,K)Fe{sub 2}As{sub 2} and electron-doped Ca10-3-8, we show that the superconducting gap modulation in the under-doped regime is intrinsic and is not induced by the coexisting static magnetic order.

    This paper considers some of the strengths and weaknesses of conducting synchronous online interviews for qualitative research. It is based on a study among gay/bisexual men that used both qualitative and quantitative methods to explore the association between seeking sex through the Internet and HIV transmission risk. Between June 2002 and January 2004, 128 gay/bisexual men living in London were interviewed one-to-one by the first author (MD) about their experience of using the Internet to find sexual partners and negotiating condom use for anal sex. Thirty-five men were interviewed online, while 93 were interviewed face-to-face (i.e. offline). This paper draws on MD's experience of conducting these interviews--both online and face-to-face. Synchronous online interviews have the advantage of being cheap, convenient and attractive to people who do not like face-to-face interviews. However, some of the social conventions and technical limitations of computer-mediated-communication can introduce ambiguity into the online dialogue. To minimize this ambiguity, both interviewer and interviewee have to edit their online interaction. One of the distinctive features of the online interview is that it emerges as a form of textual performance. This raises fundamental questions about the suitability of the synchronous online interview for exploring sensitive topics such as risky sexual behaviour.

    Abstract Background The Natural History Museum, London (NHMUK) has embarked on an ambitious programme to digitise its collections . The first phase of this programme has been to undertake a series of pilot projects that will develop the necessary workflows and infrastructure development needed to support mass digitisation of very large scientific collections. This paper presents the results of one of the pilot projects – iCollections. This project digitised all the lepidopteran specimens usually considered as butterflies, 181,545 specimens representing 89 species from the British Isles and Ireland. The data digitised includes, species name, georeferenced location, collector and collection date - the what, where, who and when of specimen data. In addition, a digital image of each specimen was taken. This paper explains the way the data were obtained and the background to the collections which made up the project. New information Specimen-level data associated with British and Irish butterfly specimens have not been available before and the iCollections project has released this valuable resource through the NHM data portal.

    Objectives: To describe the epidemiology, presentation, and diagnosis of early syphilis in 103 homosexual men in east London. Methods: A retrospective study using data from KC60 returns, the Health Protection Agency (HPA) enhanced surveillance forms and case notes. Results: 40 cases of primary (PS), 40 of secondary (SS) and 23 of early latent syphilis were identified, 33% co-infected with HIV. 41% had concurrent sexually transmitted infections (STIs). Pain featured in 35% of PS and itch in 13% of rashes. Dark ground microscopy (DGM), performed in 44 of the symptomatic cases, was positive in 37 (84%) allowing early management. Initial syphilis serology was negative in 15/40 (37%) cases of PS. 51% and 49% opted for parenteral and oral treatment, respectively. In 53/103 (51%) cases oral sex was the only risk factor. 86% of infections were UK acquired. Only 4% of contacts were seen. Conclusion: This outbreak, reflecting the resurgence of syphilis across the United Kingdom, highlights several important points. Painful chancres and itchy rash are common presentations. DGM is a highly sensitive diagnostic tool. Initial negative serological screening tests are common in PS and sero-surveillance for 3 months is recommended. The high prevalence of concomitant STIs indicates ongoing unprotected sexual intercourse. Oral sex is a significant risk factor and is a distinctly "unsafe" practice. Conventional partner notification is ineffective. Other methods of screening of the at-risk homosexual population are warranted. Continued education is required to reduce STI acquisition in homosexual men. PMID:15572625

    2014-12-01

    Rapid urbanisation results in increased water consumption in cities, requiring improved tools for understanding adaptive measures for water resources management under climate change. The energy sector is facing the same challenges and requires equally comprehensive solutions. More frequent water shortages due to climate and land use changes and potential limits on CO2 emissions from fossil fuels that science demands indicate clearly that the next step in the sustainable city development will be to look for the most efficient use of these highly interdependent resources. One of the concepts that could be used for quantifying fundamental flows in an urban environment such as water and energy is the urban metabolism framework. This paper will examine the concept of urban metabolism by quantifying amounts and trends of water and energy consumed in London by four main sectors: residential, industrial, commercial and public. Key data requirements at the sector level will be identified and initial mapping of critical factors for urban sustainability will be provided. Finally, the work will examine the potential of urban metabolism framework to provide data and information for implementing water, energy and greenhouse emissions trade-off 'fit-for-purpose' strategy for water supply security. The paper is a part of the Panta Rhei Research Initiative of the International Association of Hydrological Sciences (IAHS) under the working group of Energy and Food Impacts on Water.

    This exploratory study adopts a socio-ecological approach to examine the context of school bullying. It asks: (1) what are students' accounts of bullying practices?; (2) how are these enabled and constrained by the school-environment?; (3) how is gender implicated? Qualitative data were collected from girls in two schools in London via focus groups (one in each school; students aged 12-15) and seven semi-structured interviews (in one school; students aged 16-18); and from school policy documents. Our interpretation of girls' accounts, informed by Giddens' structuration theory, suggests that bullying practices were spatially patterned in the schools and often characterised by the regulation of girls' sexuality and sexual-harassment. Repeated acts of aggression were fluid with regard to the bully and victim role, challenging the dominant view of bullying as characterised by consistent disparities in power between individuals. Schools structured bullying behaviour via policies and practices that ignored these forms of abuse and which focused on and may have been complicit in the making of stable 'bully' and 'victim' roles, thus indirectly contributing to the reproduction of unhealthy relationships between students. In terms of gender, traditional gendered and sexual discourses appear to structure the identities of the schools and girls in our study.

    Children with von Willebrand disease (VWD) in whom DDAVP is ineffective or contraindicated require treatment with a coagulation factor concentrate containing von Willebrand factor (VWF) and factor VIII (FVIII). The aim of this study was to monitor the safety, efficacy and tolerability of Wilate(®) (a VWF:FVIII concentrate with a 1:1 ratio) used across the North London Paediatric Haemophilia Network since May 2010. In total, 47 children (aged 0.0-17.0 years) with type 1 (n = 28), type 2 (n = 7), type 3 (n = 10) and acquired VWS (n = 2) have been treated for bleeds, surgery and/or prophylaxis using 260 000 IU Wilate(®). Analysis of dose and frequency of treatment show expected responses to treatment with mean doses of 55, 50 and 50 IU kg(-1) for bleeds, surgery and prophylaxis respectively. Most bleeds responded to a single treatment. Surgical procedures were covered with clinician approved dosing schedules with 95% (39/41) reported as having excellent or good efficacy. There was no accumulation of FVIII or VWF and no thromboembolic events. This case series confirms the efficacy, safety and tolerability of Wilate(®) in neonates, children and adolescents when used on-demand, prophylactically and in the surgical setting.

  3. 'Gay times': identity, locality, memory, and the Brixton squats in 1970's London.

    PubMed

    Cook, Matt

    2013-01-01

    Through a thick description of a gay squatting community in south London in the 1970s, this piece explores the ways in which local histories complicate broader accounts of gay life, politics, and culture. Such a focus alerts us to the impact of personal encounters, of local politics, and material circumstances, of coincident local communities, of jobs (or the lack of them), and of major local events (like the Brixton riots of 1981). The local focus and the oral history sources also illuminate the complex ways in which unspoken and often unconscious imperatives associated with ethnicity, class, and the familial, social, and cultural contexts of our upbringings are played out under new and changing circumstances. Taking this approach fractures homogenizing assumptions about gay identity and community--even of a self-identified gay community like this squatting collective. It can also decentre sexuality as a primary category of identity and analysis as other factors come into sharper focus and shed light on the ebb and flow of identification and on the ways in which broader histories are woven into everyday lives. The piece thus considers different scales of analysis, the limits of identification, the inclusions and exclusions enacted when communities come together and identities coalesce, the continuities and discontinuities between broader and counter cultures (especially in relation to ideas and lived experiences of home), and the way memories of the squats and of the 1970s are modulated by subsequent national and gay politics, by AIDS, and by a profound sense of loss.

    We study the growth of London's street network in its dual representation, as the city has evolved over the past 224 years. The dual representation of a planar graph is a content-based network, where each node is a set of edges of the planar graph and represents a transportation unit in the so-called information space, i.e., the space where information is handled in order to navigate through the city. First, we discuss a novel hybrid technique to extract dual graphs from planar graphs, called the hierarchical intersection continuity negotiation principle. Then we show that the growth of the network can be analytically described by logistic laws and that the topological properties of the network are governed by robust log-normal distributions characterizing the network's connectivity and small-world properties that are consistent over time. Moreover, we find that the double-Pareto-like distributions for the connectivity emerge for major roads and can be modeled via a stochastic content-based network model using simple space-filling principles.

    Three studies are reported on the development of a four-disc version of the Tower of London test of planning ability. The first (n = 138) involved the selection of items based on rational and empirical criteria to provide a short test of graded difficulty suitable for use with children and clinical populations. The second study (n = 480) checked the properties of the 10-item test on a new sample and in addition examined the internal consistency and factor structure of the test. The third study (n = 61) examined the test-retest reliability of the test over a period of 1 month. The difficulty level of the test remained relatively stable from sample to sample and was sensitive to linear trend in performance from age 5 years up to 30 years. Total score did not reflect the action of a single underlying construct but rather appeared to index a number of factors. Scores were reasonably stable over the 1-month period studied, at least for the children's sample employed. The four-disc version is a promising method of assessing planning in children and adolescents in clinical situations.

  6. Are people with HIV in London able to die where they plan?

    Being able to die where you plan is a measure of quality of life near death, in that it implies awareness of diagnosis and prognosis, adequate symptom control and involvement in decision-making in late-stage HIV disease. This study presents trends in place of death for patients attending a large central London HIV centre and examines whether patients dying over a 6-month period in 1994 were able to die where they planned. Early in the epidemic almost all people with HIV died in hospital, but in the late 1980s there was an increase in death at home and in hospices. Of people attending this hospital in 1994, 46% died in hospital, 31% at home, 20% in hospices and 2% abroad. A total of 59% of deaths were where the dying person had planned. Most unplanned deaths were in hospital, two-thirds being due to an unexpected deterioration which precluded planning. The rest were a mixture of people waiting for discharge to die elsewhere, and people who wished to continue active treatment. This pattern of place of death is unlikely to change in the near future. It is therefore essential that hospitals can provide for the needs of patients dying on acute wards.

    Crime is an ubiquitous part of society. The way people express their concerns about crimes has been of particular interest to the scientific community. Over time, the numbers and kinds of available communication channels have increased. Today, social media services, such Twitter, present a convenient way to express opinions and concerns about crimes. The main objective of this study is to explore people’s perception of homicides, specifically, how the characteristics and proximity of the event affect the public’s concern about it. The analysis explores Twitter messages that refer to homicides that occurred in London in 2012. In particular, the dependence of tweeting propensity on the proximity, in space and time, of a crime incident and of people being concerned about that particular incident are examined. Furthermore, the crime characteristics of the homicides are analysed using logistic regression analysis. The results show that the proximity of the Twitter users’ estimated home locations to the homicides’ locations impacts on whether the associated crime news is spread or not and how quickly. More than half of the homicide related tweets are sent within the first week and the majority of them are sent within a month of the incident’s occurrence. Certain crime characteristics, including the presence of a knife, a young victim, a British victim, or a homicide committed by a gang are predictors of the crime-tweets posting frequency.

    Residential location is thought to influence people’s well-being, but different individuals may value residential areas differently. We examined how life satisfaction and personality traits are geographically distributed within the UK London metropolitan area, and how the strength of associations between personality traits and life satisfaction vary by residential location (i.e., personality–neighborhood interactions). Residential area was recorded at the level of postal districts (216 districts, n = 56,019 participants). Results indicated that the strength of associations between personality traits and life satisfaction depended on neighborhood characteristics. Higher openness to experience was more positively associated with life satisfaction in postal districts characterized by higher average openness to experience, population density, and ethnic diversity. Higher agreeableness and conscientiousness were more strongly associated with life satisfaction in postal districts with lower overall levels of life satisfaction. The associations of extraversion and emotional stability were not modified by neighborhood characteristics. These findings suggest that people’s life satisfaction depends, in part, on the interaction between individual personality and particular features of the places they live. PMID:25583480

    Insomnia in elderly people has traditionally been regarded as inevitable and trivial. A longitudinal study was undertaken to examine the prevalence of sleep disturbance among elderly people in an inner London community and its association with demographic variables, depression, dementia and disability. Those aged 65 years and over living at home were interviewed using a validated and reliable semi-structured interview schedule. A total of 705 people were interviewed in 1987-88 and 524 were re-interviewed in 1990. Subjective sleep disturbance was found to be common (33% and 43%, respectively). Sleep disturbance was associated with being a woman, being unmarried, living alone, disability, and current and future depression, but not with dementia or older age. The best predictor of future depression in elderly people who were not depressed was current sleep disturbance. In the presence of current sleep disturbance, the traditional predictors of depression--being a woman, having a disability, being unmarried, living alone and being older--did not contribute further. This study has shown that sleep disorder is associated with pathology. Insomnia in elderly people requires assessment and this must be accompanied by the treatment of underlying disorders and monitoring of future health. PMID:8292414

  10. Biomedical practices from a patient perspective. Experiences of Polish female migrants in Barcelona, Berlin and London.

    This paper focuses on the diversity in patients' experience of bio-medicine and contrasts it with the normative view characteristic of health professionals. Ethnographic fieldwork among Polish migrant women in London, Barcelona and Berlin included interviews about their experiences with local healthcare and health professionals. Themes drawn from the narratives are differences between the cities in terms of communication between patients and health professionals, respect for patients' choices and dignity, attitudes to pregnancy and birth (different levels of medicalization), and paediatric care. It is argued that patients continuously negotiate among their own views and expectations based on previous experiences and knowledge from personal communication; internet forums and publications; and the offer of medical services in the countries of their settlement. Patients experience pluralism of therapeutic traditions within and outside bio-medicine. In turn, representatives of bio-medicine are rarely aware of other medical practices and beliefs and this leads to various misunderstandings. By highlighting the pluralism of medical practices in European countries and the increasing mobility of patients, this case study has useful implications for medical anthropologists and health professionals in a broader Western context, such as raising sensitivity to different communication strategies and a diversity of curing traditions and expectations.

    Abstract Purpose  Bridging the gap between professionals and communities and establishing new forms of partnership is essential if service provision is to be made more responsive and accountable. This article describes an innovative approach to creating the basis for partnerships to address community wellbeing on an estate in south London. Methods  Drawing on participatory appraisal and action planning methods, and drawing together residents and professionals within and beyond the health service, a participatory wellbeing assessment exercise was carried out on a housing estate with a population of around 6000 people, involving just under 10% of residents. Results  The participatory wellbeing assessment exercise served as a means of seeking to bridge different perceptions, priorities and perspectives on wellbeing and forge new relationships, alliances and partnerships for change. Creating this vehicle for change also created opportunities for local people to participate in community wellbeing issues. This, in turn, strengthened connections between health policy, provision and grassroots community health development, broadening opportunities for service responsiveness and citizen involvement. Conclusion  Broadening involvement in assessing and determining priorities for improving wellbeing can serve to do more than enable citizens to engage more directly in making and shaping the policies that affect their lives. It can also serve as a way of establishing new kinds of partnerships across and within the statutory and non‐statutory services, opening up space for new, more ‘joined up’ forms of work that help to bridge the gap between citizens and services.

    2013-12-01

    In recent years, there is an emerging 'green and sustainable remediation' (GSR) movement. It is drawing increasing attention from both the government and the industry, because this GSR movement is promising in accelerating process in addressing the contaminated land issue, by overcoming regulatory barriers, encouraging technological innovation, and balancing life cycle environmental stewardship with economic vitality and social well-being. Life cycle assessment (LCA) has been increasingly used by both researchers and industrial practitioners in an initiative to make environmental remediation greener and more sustainable. Life cycle sustainability assessment (LCSA), aiming at expanding the traditional LCA model in both breadth and depth (e.g. to incorporate both environmental and social-economic sustainability), is an important research direction in the existing LCA research field. The present study intends to develop a LCSA method based on a hybrid LCA model and economic input-output (EIO) data. The LCSA method is applied to a contaminated sediment remediation project conducted at the London Olympic Park site.

    Twenty five homosexual men from London, 14 of whom had persistent lymphadenopathy and 11 of whom did not, were tested for immunity to Epstein-Barr (EB) virus. All yielded positive results to serological tests for the viral capsid antibody, and 11 had antibodies to the early antigen. Thirteen out of 17 were excreting virus into the saliva; culture of peripheral blood mononuclear cells from two of these patients showed no detectable regression induced by T cells that was specific to EB virus. No differences were found between the patients with and without lymphadenopathy. Peripheral blood B cells from six patients with hypergammaglobulinaemia were double stained for cytoplasmic immunoglobulin and EB viral nuclear antigen, and in all cases the activated B cells producing immunoglobulin did not contain EB nuclear antigen. Similarly, lymph node biopsy specimens from five patients showed no cells with EB nuclear antigen. These results indicate that although homosexual men have a high incidence of reactivated infection with EB virus, this viral infection is not the cause of the polyclonal activation of B cells seen in peripheral blood and is not implicated in the aetiology of the lymphadenopathy found in these men.

  14. The tree as evolutionary icon: TREE in the Natural History Museum, London.

    Hellström, Nils Petter

    2011-01-01

    As part of the Darwin celebrations in 2009, the Natural History Museum in London unveiled TREE, the first contemporary artwork to win a permanent place in the Museum. While the artist claimed that the inspiration for TREE came from Darwin's famous notebook sketch of branching evolution, sometimes referred to as his "tree of life" drawing, this article emphasises the apparent incongruity between Darwin's sketch and the artist's design -- best explained by other, complementary sources of inspiration. In the context of the Museum's active participation in struggles over science and religion, the effect of the new artwork is contradictory. TREE celebrates Darwinian evolutionism, but it resonates with deep-rooted, mythological traditions of tree symbolism to do so. This complicates the status of the Museum space as one of disinterested, secular science, but it also contributes, with or without the intentions of the Museum's management, to consolidate two sometimes conflicting strains within the Museum's history. TREE celebrates human effort, secular science and reason -- but it also evokes long-standing mythological traditions to inspire reverence and remind us of our humble place in the world.

    Young people attending genitourinary medicine services are at high risk of unplanned pregnancy. We performed a retrospective cohort study to identify characteristics of pregnant teenagers accessing an inner London genitourinary medicine service. There were 481 pregnancies in 458 teenagers with 54 previous pregnancies and 46 previous terminations of pregnancy. The under-18 and under-16 teenage pregnancy rates were 92.1 and 85.8 per 1000 age-matched clinic attendees, respectively. Median age was 17.1 years. 'Black Other' teenagers ('Black British', 'Mixed White-Black Caribbean' and 'Mixed White-Black African') were over-represented, compared to our clinic population, while those of White ethnicity were under-represented. Few pregnancies (1.5%) were planned with the majority (64%) intending terminations of pregnancy. Most teenagers did not use consistent contraception. Two-thirds of patients had attended genitourinary medicine services in the past and sexually transmitted infection prevalence at presentation was high. Effectively targeting the sexual and reproductive health needs of teenage genitourinary medicine clinic attendees may have a significant impact on reducing sexually transmitted infections, unplanned pregnancy and terminations of pregnancy in this group.

    Epidemiological studies have linked daily concentrations of urban air pollution to mortality, but few have investigated specific traffic sources that can inform abatement policies. We assembled a database of >100 daily, measured and modelled pollutant concentrations characterizing air pollution in London between 2011 and 2012. Based on the analyses of temporal patterns and correlations between the metrics, knowledge of local emission sources and reference to the existing literature, we selected, a priori, markers of traffic pollution: oxides of nitrogen (general traffic); elemental and black carbon (EC/BC) (diesel exhaust); carbon monoxide (petrol exhaust); copper (tyre), zinc (brake) and aluminium (mineral dust). Poisson regression accounting for seasonality and meteorology was used to estimate the percentage change in risk of death associated with an interquartile increment of each pollutant. Associations were generally small with confidence intervals that spanned 0% and tended to be negative for cardiovascular mortality and positive for respiratory mortality. The strongest positive associations were for EC and BC adjusted for particle mass and respiratory mortality, 2.66% (95% confidence interval: 0.11, 5.28) and 2.72% (0.09, 5.42) per 0.8 and 1.0 μg/m(3), respectively. These associations were robust to adjustment for other traffic metrics and regional pollutants, suggesting a degree of specificity with respiratory mortality and diesel exhaust containing EC/BC.

    The environmental impact of diesel-fueled buses can potentially be reduced by the adoption of alternative propulsion technologies such as lean-burn compressed natural gas (LB-CNG) or hybrid electric buses (HEB), and emissions control strategies such as a continuously regenerating trap (CRT), exhaust gas recirculation (EGR), or selective catalytic reduction with trap (SCRT). This study assessed the environmental costs and benefits of these bus technologies in Greater London relative to the existing fleet and characterized emissions changes due to alternative technologies. We found a >30% increase in CO2 equivalent (CO2e) emissions for CNG buses, a <5% change for exhaust treatment scenarios, and a 13% (90% confidence interval 3.8-20.9%) reduction for HEB relative to baseline CO2e emissions. A multiscale regional chemistry-transport model quantified the impact of alternative bus technologies on air quality, which was then related to premature mortality risk. We found the largest decrease in population exposure (about 83%) to particulate matter (PM2.5) occurred with LB-CNG buses. Monetized environmental and investment costs relative to the baseline gave estimated net present cost of LB-CNG or HEB conversion to be $187 million ($73 million to $301 million) or $36 million ($-25 million to $102 million), respectively, while EGR or SCRT estimated net present costs were $19 million ($7 million to $32 million) or $15 million ($8 million to $23 million), respectively.

    2014-05-01

    The daily evolution of the Urban Convective Boundary Layer is of importance in terms of the dispersion of pollutants and for initializing models. In particular, morning and afternoon transition periods are of interest for initializing prognostic models and also for basic understanding of significant processes such as the nocturnal low level jet (LLJ) and the whole structure of the nocturnal atmospheric boundary layer. Moreover, significant differences in the diurnal cycle of fluxes and boundary layer depths of urban and rural sites are expected due to different surface energy balance observed in urban and rural areas. Yet, long term observations of fluxes and boundary layer depth at both urban and rural sites are rear. The aim of the present study is to examine the major phases (morning expansion, midday developed and afternoon decay) of the diurnal cycle of the Convective Boundary Layer. Towards this aim more than 1 year of measurements of a HALO Photonics Doppler Lidar and eddy covariance systems deployed in the frame of the ACTUAL (Advanced Climate Technology Urban Atmospheric Laboratory) project in central London, UK were analyzed. The urban lidar was operating in two modes: continuous stare mode (pointing vertically) and Doppler Beam Swinging (DBS) mode measuring the turbulence and the wind speed vertical profile respectively. The urban CBL is compared to the CBL over a nearby rural site (Chilbolton) and differences in urban and rural boundary layers are analyzed in terms of atmospheric stability and direction of the prevailing flow.

  19. Prevalence and distribution of osteoarthritis in a population from Georgian and early Victorian London.

    The prevalence of osteoarthritis was calculated in adult skeletons excavated from the crypt of Christ Church, Spitalfields in east London, which was used for burial between 1729 and 1869. Age and sex specific prevalences were also calculated for a subsample of the group for whom age and sex were accurately known from surviving coffin plates. Prevalences were slightly higher in men than in women, except for generalised osteoarthritis. The principal sites affected were the acromioclavicular joints, the facet joints of the spine, and the hands. Osteoarthritis of the large joints was relatively uncommon; osteoarthritis of the hip occurred in 4/360 (1.1%) of men and 10/346 (2.9%) of women and of the knee in 3/360 (0.8%) of men and 18/346 (5.2%) of women. This last difference was statistically significant. A comparison with modern data suggests that the prevalence of osteoarthritis at Spitalfields was lower than in the contemporary population, and some explanations for this apparent difference are considered.

    Sherborn's work on the Foraminifera clearly provided the initial spark to compile the major indexes for which he is famous. Contact and help from famous early micropalaeontologists such as T. Rupert Jones and Fortescue William Millett led Sherborn to produce his Bibliography of Foraminifera and subsequently a two-part Index of Foraminiferal Genera and Species. Edward Heron-Allen, whose mentor was Millett, was subsequently inspired by the bibliography to attempt to acquire every publication listed. This remarkable collection of literature was donated to the British Museum (Natural History) in 1926 along with the foraminiferal collections Heron-Allen had mainly purchased from early micropalaeontologists. This donation forms the backbone of the current NHM micropalaeontological collections. The NHM collections contain a relatively small amount of foraminiferal material published by Sherborn from the London Clay, Kimmeridge Clay and Speeton Clay. Another smaller collection reflects his longer-term interest in the British Chalk following regular fieldwork with A. W. Rowe. Other collections relating to Sherborn's early published work, particularly with T. R. Jones, are not present in the collections but these collections may have been sold or deposited elsewhere by his co-workers.

    Planning on the 4-disk version of the Tower of London (TOL4) was examined in stroke patients and unimpaired controls. Overall TOL4 solution scores indicated impaired planning in the frontal stroke but not non-frontal stroke patients. Consistent with the claim that processing the relations between current states, intermediate states, and goal states is a key process in planning, the domain-general relational complexity metric was a good indicator of the experienced difficulty of TOL4 problems. The relational complexity metric shared variance with task-specific metrics of moves to solution and search depth. Frontal stroke patients showed impaired planning compared to controls on problems at all three complexity levels, but at only two of the three levels of moves to solution, search depth and goal ambiguity. Non-frontal stroke patients showed impaired planning only on the most difficult quaternary-relational and high search depth problems. An independent measure of relational processing (viz., Latin square task) predicted TOL4 solution scores after controlling for stroke status and location, and executive processing (Trail Making Test). The findings suggest that planning involves a domain-general capacity for relational processing that depends on the frontal brain regions.

    The Netherlands Society of Neurology evolved from the Society of Psychiatry founded in 1871. The name was changed into Netherlands Society of Psychiatry and Neurology (NSPN) in 1897. In the same year, the word neurology was also added to the name of the journal. The Society steadily blossomed, but in 1909 the first signs of dissatisfaction occurred: the Amsterdam Neurologists Society was founded. A few split-offs would follow. The number of members of the NSPN increased from 205 in 1920 to 585 in 1960. In the early 1960s, the Society was reorganised and would consist of two sections, one for psychiatry and one for neurology. However, this would not last, as a full separation was established in 1974. For several reasons, the name of the journal was changed four times until it assumed its present name in 1974. The 100th volume of CNN was not published, as expected. in 1996, but in 1998, because of two skipped publication years, one during WWII and another in the 1970s. During the last decades of the nineteenth century, teaching of neurology was mostly given within the frame of psychiatry, following the German tradition of 'brainpsychiatry' (organic or biologic psychiatry). The first official chair of psychiatry was founded at Utrecht, 1893 (Winkler). In Amsterdam, private teachers such as Delprat taught 'electro-therapy and nervous diseases' since the 1880s. The first extraordinary chair of neurology and electrotherapy was founded for his successor, Wertheim Salomonson in 1899. The first university clinic for psychiatry and neurology started at the Amsterdam Municipal University, when Winkler became professor of psychiatry and neurology in Amsterdam in 1896. Around the turn of the century, chairs of psychiatry and neurology were also founded in Groningen and Leiden. Separate chairs for neurology and psychiatry appeared in Amsterdam in 1923 and in Utrecht in 1936. Following an initiative of Brouwer, the first neurological university clinic opened its doors in

    Outbreaks of serious infections associated with heroin use in persons who inject drugs (PWIDs) occur intermittently and require vigilance and rapid reporting of individual cases. Here, we give a firsthand account of the cases in London during an outbreak of heroin-associated anthrax during 2009-2010 in the United Kingdom. This new manifestation of anthrax has resulted in a clinical manifestation distinct from already recognized forms. During 2012-13, additional cases of heroin-associated anthrax among PWIDs in England and other European countries were reported, suggesting that anthrax-contaminated heroin remains in circulation. Antibacterial drugs used for serious soft tissue infection are effective against anthrax, which may lead to substantial underrecognition of this novel illness. The outbreak in London provides a strong case for ongoing vigilance and the use of serologic testing in diagnosis and serologic surveillance schemes to determine and monitor the prevalence of anthrax exposure in the PWID community.

    Recent measurements of the doping dependence of the London penetration depth λ(x) at low T in clean samples of isovalent BaFe2(As1-xPx)2 at T≪Tc [Hashimoto et al., Science 336, 1554 (2012)SCIEAS0036-8075] revealed a peak in λ(x) near optimal doping x=0.3. The observation of the peak at T≪Tc, points to the existence of a quantum critical point beneath the superconducting dome. We associate such a quantum critical point with the onset of a spin-density-wave order and show that the renormalization of λ(x) by critical magnetic fluctuations gives rise to the observed feature. We argue that the case of pnictides is conceptually different from a one-component Galilean invariant Fermi liquid, for which correlation effects do not cause the renormalization of the London penetration depth at T=0.

    The authors historically situate the London Kleinian development in terms of the small-group collaborations and adversaries that arose during the course of Melanie Klein's career. Some collaborations later became personally adversarial (e.g., those Klein had with Glover and Schmideberg); other adversarial relationships forever remained that way (with A. Freud); while still other long-term collaborations became theoretically contentious (such as with Winnicott and Heimann). After the Controversial Discussions in 1944, Klein marginalized one group of supporters (Heimann, Winnicott, and Riviere) in favor of another group (Rosenfeld, Segal, and Bion). After Klein's death in 1960, Bion maintained loyalty to Klein's ideas while quietly distancing his work from the London Klein group, immigrating to the United States in 1968.

    Airborne measurements within the urban mixing layer (360 m) over Greater London are used to quantify CO(2) emissions at the meso-scale. Daytime CO(2) fluxes, calculated by the Integrative Mass Boundary Layer (IMBL) method, ranged from 46 to 104 μmol CO(2) m(-2) s(-1) for four days in October 2011. The day-to-day variability of IMBL fluxes is at the same order of magnitude as for surface eddy-covariance fluxes observed in central London. Compared to fluxes derived from emissions inventory, the IMBL method gives both lower (by 37%) and higher (by 19%) estimates. The sources of uncertainty of applying the IMBL method in urban areas are discussed and guidance for future studies is given.

    Purpose The Examining Neighbourhood Activities in Built Living Environments in London (ENABLE London) project is a natural experiment which aims to establish whether physical activity and other health behaviours show sustained changes among individuals and families relocating to East Village (formerly the London 2012 Olympics Athletes' Village), when compared with a control population living outside East Village throughout. Participants Between January 2013 and December 2015, 1497 individuals from 1006 households were recruited and assessed (at baseline) (including 392 households seeking social housing, 421 seeking intermediate and 193 seeking market rent homes). The 2-year follow-up rate is 62% of households to date, of which 57% have moved to East Village. Findings to date Assessments of physical activity (measured objectively using accelerometers) combined with Global Positioning System technology and Geographic Information System mapping of the local area are being used to characterise physical activity patterns and location among study participants and assess the attributes of the environments to which they are exposed. Assessments of body composition, based on weight, height and bioelectrical impedance, have been made and detailed participant questionnaires provide information on socioeconomic position, general health/health status, well-being, anxiety, depression, attitudes to leisure time activities and other personal, social and environmental influences on physical activity, including the use of recreational space and facilities in their residential neighbourhood. Future plans The main analyses will examine the changes in physical activity, health and well-being observed in the East Village group compared with controls and the influence of specific elements of the built environment on observed changes. The ENABLE London project exploits a unique opportunity to evaluate a ‘natural experiment’, provided by the building and rapid occupation of East

    The causal interpretation of reported associations between daily air pollution and daily admissions requires consideration of residual confounding, correlation between pollutants, and effect modification. If results obtained in Hong Kong and London--which differ in climate, lifestyle, and many other respects--were similar, a causal association would be supported. We used identical statistical methods for the analysis in each city. Associations between daily admissions and pollutant levels were estimated using Poisson regression. Nonparametric smoothing methods were used to model seasonality and the nonlinear dependence of admissions on temperature, humidity, and influenza admissions. For respiratory admissions (> or = 65 years of age), significant positive associations were observed with particulate matter < 10 microm in aerodynamic diameter (PM(10), nitrogen dioxide, sulfur dioxide, and ozone in both cities. These associations tended to be stronger at shorter lags in Hong Kong and at longer lags in London. Associations were stronger in the cool season in Hong Kong and in the warm season in London, periods during which levels of humidity are at their lowest in each city. For cardiac admissions (all ages) in both cities, significant positive associations were observed for PM(10), NO(2), and SO(2) with similar lag patterns. Associations tended to be stronger in the cool season. The associations with NO(2) and SO(2) were the most robust in two-pollutant models. Patterns of association for pollutants with ischemic heart disease were similar in the two cities. The associations between O(3) and cardiac admissions were negative in London but positive in Hong Kong. We conclude that air pollution has remarkably similar associations with daily cardiorespiratory admissions in both cities, in spite of considerable differences between cities in social, lifestyle, and environmental factors. The results strengthen the argument that air pollution causes detrimental short

    Basic Immunology has had only two significant public priority disputes. The first began in the late 1650s and concerned the recognition of the peripheral network of vessels which collects lymph throughout the body. The publication of this major anatomical discovery prompted a priority feud discussed in a previous paper. The subject of this essay is the second dispute which occurred a century later in the late 1750s. It focused on the function of the lymphatic system and precipitated a heated war of words between a young Scotch medical graduate (Alexander Monro) and a noted London anatomist (William Hunter). Their published charges and responses ranged from feigned respect to ad hominen invectives. But in retrospect, the priority claims of both were precluded by the observations and speculations of an Englishman (Francis Glisson) a full century before. The several editions of his work were unknown to Hunter and Monro at the inception of their feud.

    With minimal information on sexual health provision during mass-gathering events, our aim was to describe the use of sexual health, contraceptive, sex worker and sexual assault services during the London 2012 Olympics. We analysed data from five sources. One contraceptive service provider reported a 10% increase in attendance during the main Games, while emergency contraception prescriptions rose during the main Olympics, compared to the week before, but were similar or lower than at the beginning and end of the summer period. A health telephone advice line reported a 16% fall in sexual health-related calls during the main Olympics, but a 33% increase subsequently. London sexual assault referral centres reported that 1.8% of sexual assaults were Olympics-linked. A service for sex workers reported that 16% started working in the sex industry and 7% moved to London to work during the Olympics. Fifty-eight per cent and 45% of sex workers reported fewer clients and an increase in police crack-downs, respectively. Our results show a change in activity across these services during the 2012 summer, which may be associated with the Olympics. Our data are a guide to other services when anticipating changes in service activity and planning staffing for mass-gathering events.

    Objective To explore awareness of and participation in cervical screening services in women from Poland, Slovakia and Romania living in London, UK. Methods Three qualitative studies were carried out in London in 2008–2009: an interview study of professionals working with Central and Eastern European migrants (n=11); a focus group study including three Polish, one Slovak and one Romanian focus group; and an interview study of Polish (n=11), Slovak (n=7) and Romanian (n=2) women. Results Awareness of the cervical screening programme was good, but understanding of the purpose of screening was sometimes limited. Some women were fully engaged with the UK screening programme; others used screening both in the UK and their countries of origin; and a third group only had screening in their home countries. Women welcomed the fact that screening is free and that reminders are sent, but some were concerned about the screening interval and the age of the first invitation. Conclusions Migrant women from Poland, Slovakia and Romania living in London vary in their level of participation in the National Health Service Cervical Screening Programme. More needs to be done to address concerns regarding screening services, and to ensure that language is not a barrier to participation. PMID:22219504

    A new surveillance system was developed to detect possible new or emerging infections presenting as undiagnosed serious infectious illness (USII) for use during the London 2012 Olympic and Paralympic Games. Designated clinicians in sentinel adult and paediatric intensive care units (ICU/ PICUs) reported USII using an online reporting tool or provided a weekly nil notification. Reported cases were investigated for epidemiological links. A pilot study was undertaken for six months between January and July 2011 to evaluate the feasibility and acceptability of the system. In this six-month period, 5 adults and 13 children were reported by six participating units (3 ICUs, 3 PICUs). Of these 18 patients, 12 were reported within four days after admission to an ICU/PICU. Nine patients were subsequently diagnosed and were thus excluded from the surveillance. Therefore, only nine cases of USII were reported. No clustering was identified.On the basis of the pilot study, we conclude that the system is able to detect cases of USII and is feasible and acceptable to users. USII surveillance has been extended to a total of 19 sentinel units in London and the south-east of England during the London 2012 Olympic and Paralympic Games.

  16. Mapping the evolution of 'food deserts' in a Canadian city: Supermarket accessibility in London, Ontario, 1961–2005

    Background A growing body of research suggests that the suburbanization of food retailers in North America and the United Kingdom in recent decades has contributed to the emergence of urban 'food deserts', or disadvantaged areas of cities with relatively poor access to healthy and affordable food. This paper explores the evolution of food deserts in a mid-sized Canadian city (London, Ontario) by using a geographic information system (GIS) to map the precise locations of supermarkets in 1961 and 2005; multiple techniques of network analysis were used to assess changing levels of supermarket access in relation to neighbourhood location, socioeconomic characteristics, and access to public transit. Results The findings indicate that residents of inner-city neighbourhoods of low socioeconomic status have the poorest access to supermarkets. Furthermore, spatial inequalities in access to supermarkets have increased over time, particularly in the inner-city neighbourhoods of Central and East London, where distinct urban food deserts now exist. Conclusion Contrary to recent findings in larger Canadian cities, we conclude that urban food deserts exist in London, Ontario. Policies aimed at improving public health must also recognize the spatial, as well as socioeconomic, inequities with respect to access to healthy and affordable food. Additional research is necessary to better understand how supermarket access influences dietary behaviours and related health outcomes. PMID:18423005

    This paper examines the politics of mobility which surrounded the London 2012 Olympics. We provide a critical discussion of the mobility conflicts, problems and criticisms which emerged from our research with local people in the Stratford and wider Newham areas of London, where most Olympic events were located. The paper is divided into four broad parts. First, we identify and discuss the relevant components of the 'mobilities paradigm' in social science which underpin our analysis. Second, we briefly outline our research methods, centring particularly on fieldwork and interviews with different social groups. Third, we examine in detail the six main themes of mobility politics which were evident at London 2012, relating to social context, event construction, event mobility systems, commercial mobilities, the mobile politics of exclusion, and contested modes of mobility. In doing so, we seek to extend the mobilities paradigm by introducing various concepts and keywords - notably on the three-speed city, entryability, mobility panics, instrumental mobility, and corporate kettling - which may be utilized by social scientists to examine mobility systems in other social contexts. We conclude by reaffirming the significance of mobility-focused research at sport and other mega-events, and by indicating future lines of inquiry for social scientists.

    Executive dysfunction in those high on traits of psychopathy has often been reported, with many disagreements as to the nature of the dysfunction. We aimed to see if tests of planning and rule acquisition/adherence would discriminate those high on psychopathic traits. A battery of executive function tests (Tower of London, Brixton Spatial Anticipation, and Hayling Sentence Completion Tasks) was given to 28 British male prisoners. Psychopathy was measured using the Psychopathy Checklist-Revised. High psychopathy was related to reduced planning in the Tower of London Test and poor rule-adherence on the Brixton Test. Other tests of executive function were not related to psychopathy. The results appear supportive of the notion that function of the orbitofrontal cortex (OFC) is dysfunctional in psychopathy whilst that of the dorsolateral prefrontal cortex (DLPFC) is normal and suggest that impulsivity in those high on psychopathy traits impedes planning and rule following. We suggest the adapted Tower of London Test and the Brixton Test could be useful objective measures of this type of impulsivity in offenders which could help identify key treatment goals.

    In the late nineteenth and early twentieth centuries, British physicians led the way in tropical medicine research. Several years later scientific advances had slowed, and Fairley's numerous contributions were thus most welcome. Neil Hamilton Fairley was born of Scottish parents at Victoria, Australia. After qualification at Melbourne, he joined the Australian Army Medical Service (AAMS) and after several minor research projects, made valuable contributions to the understanding of tropical sprue at Bombay (now Mumbai), India. However, Fairley's major researches were carried out during World War II (1939-45). Together with J S K Boyd he demonstrated the great value of sulphaguanidine in bacillary dysentery. Working in northern Australia and the south-Pacific region, he both contributed to elucidation of the Plasmodium vivax life-cycle, and more importantly demonstrated the value of alternative anti-malarial compounds to quinine (which was not readily available). Back in London after the war, Fairley briefly occupied the Wellcome Chair of Tropical Medicine, strongly supported London's clinical tropical medicine, and was subsequently knighted in 1950.
