Les Très Riches Heures et les Heures Bedford

The article presents new stylistic material in support of the discovery (in 2005) that the Bedford Hours were designed in the years 1414-1415, at the same time as the Très Riches Heures du duc de Berry. The Bedford Hours would appear to have been made for the dauphin, Louis de Guyenne, in light of the occurrence of several of his emblems under the principle miniatures, as well as the calendar programme, which is inspired by Ovid’s Fasti. The identification of the heraldry in the miniature of the history of the fl eur de lis (f. 288v) by Michel Pastoureau demonstrates that the miniature also represents the coronation of Henry V in 1429 in the presence of Philippe le Bon, Anne de Bourgogne and John de Mowbray, duke of Norfolk and earl marshall.

A simple and economic slide micro-immunoenzymatic (Micro-SIA) test for epidemiological studies of toxoplasmosis

A slide micro-immunoenzymatic assay (micro-SIA) to detectantibodies to non-particulate Toxoplasma gondii antigens is described. This assay allows the diagnosis of toxoplasmosis infection in about 1 hr. Twenty-four determinations can be performed per slide. Five hundred ng of antigen and 5 or 10 µl drop of each reactive are necessary per well. The clear contrast of colours obtained for negative and positive sera after the test is finished, allows direct discrimination of the results. However, it is possible to quantify the results of the reaction using a minireader. Sera dilution cutoff value, determined as themost frequent titre for the general population, is 1:100. The toxoplasma micro-SIA correlates well with indirect immunofluorescence (IIF), its sensitivity is atleast three times as much as IIF. The test has an intra and inter assay variation coefficient of 5.46 per cent and of 6.24 per cent respectively. Sera obtained at random from argentinian people were analyzed and a 56 per cent of infection was found. The main features of the Toxoplasma micro-SIA are its simplicity, sensitivity, reproducibility, and the virtual absence of background making it very suitable for screening tests.

Visceral leishmaniasis in Teresina, state of Piauí, Brazil: preliminary observations on the detection and transmissibility of canine and sandfly infections

A Leishmania donovani-complex specific DNA probe was usedto confirm the widespread dissemination of amastigotes in apparently normal skinof dogs with canine visceral leishmaniasis. When Lutzomyia longipalpis were fed on abnormal skin of five naturally infected dogs 57 of 163 (35 per cent) fliesbecame infected: four of 65 flies (6 per cent) became infected when fed on apparently normal skin. The bite of a single sandfly that had fed seven days previouslyon a naturally infected dog transmitted the infection to a young dog from a non-endemic area. Within 22 days a lesion had developed at the site of the infectivebite (inner ear): 98 days after infection organisms had not disseminated throughout the skin, bone marrow, spleen or liver and the animal was still serologically negative by indirect immunofluorescence and dot-enzyme-linked immunosorbent assay. When fed Lu. longipalpis were captured from a kennel with a sick dog known to be infected, 33 out of 49 (67 per cent) of flies contained promastigotes. In contrast only two infections were detected among more than 200 sandflies captured in houses. These observations confirm the ease of transmissibility of L.chagasi from dog to sandfly to dog in Teresina. It is likely that canine VL is the major source of human VL by the transmission route dog-sandfly-human. the Lmet2 DNA probe was a useful epidemiological tool for detecting L. chagasi in sandflies.

In-depth assessment delivers the verdict on the Government�۪s promise of a more equal society

An independent and detailed expert analysis of a decade of reforms (published 25 February) takes up the challenge made by Peter Mandelson in 1997 to “judge us after ten years of success in office. For one of the fruits of that success will be that Britain has become a more equal society.����”Commissioned by the Joseph Rowntree Foundation, the study, by a team led by LSE’s Centre for Analysis of Social Exclusion, shows sharp contrasts between different policy areas. Notable success stories include reductions in child and pensioner poverty, improved education outcomes for the poorest children and schools, and narrowing economic and other divides between deprived and other areas.But health inequalities continued to widen, gaps in incomes between the very top and very bottom grew, and poverty increased for working-age people without children.����In several policy areas there was a marked contrast between the first half of the New Labour period and the second half, when progress has slowed or even stalled.John Hills, one of the leaders of study, said, “Whether Britain has moved towards becoming a ‘more equal society’ depends on what you look at, and when. Where clear initiatives were taken, results followed. But as the growth of living standards slowed, even well before the recession, and public finances tightened, momentum seems to have been lost in several key areas.”Kitty Stewart added, “The government can take heart from achievements such as the reduction in child poverty up to 2004.����Recent data show that by then, child well-being in the UK had begun to move up the European league table from its dismal showing at the start of the decade that formed the basis of UNICEF’s damning 2007 report. But even with improved figures, Britain was still left with one of the highest rates of child poverty out of the 15 original EU members, and the latest figures show it had increased again by 2006/7.”����The study concludes that the decade from 1997 was favourable to an egalitarian agenda in several ways: the economy grew continuously; the government had large majorities and aspired to create more equality; and public attitudes surveys suggested pent-up demand for more public expenditure. But that environment now looks very uncertain, not just in the near future, but also in the longer term.����Fiscal pressures from an ageing society could further constrain resources available for redistribution, and public attitudes towards the benefit system have hardened while support for redistribution has declined.Hills added, “The 1980s and 1990s showed that hoping that rapid growth in living standards at the top would ‘trickle down’ to those at the bottom did not work.����The period since 1997 has shown that gains are possible through determined interventions, but they require intensive and continuous effort to be sustained.”JRF Chief Executive Julia Unwin added, “We know the potential impact the deepening recession will have on those already living in poverty. This book provides an important, timely and comprehensive assessment of where we are and what remains to be done.”

Dementia 2013: The hidden voice of loneliness

Dementia 2013: The hidden voice of loneliness is Alzheimer's Society's annual report examining the quality of life for people with dementia.The report found that over half of the general public (54 per cent) believe that people with dementia have a bad quality of life. This was echoed in the feedback from people with dementia with 70 per cent saying they had stopped doing things they used to due because of lack of confidence. The majority of people with dementia also felt anxious or depressed (63 per cent) and a third of people (35 per cent) said they’d lost friends after a diagnosis.��Other key statistics in Dementia 2013 include:38 per cent of all people with dementia said they felt lonelyPeople with dementia said they relied on relatives and friends for social contact and yet almost a quarter (21 per cent) speak to friends or family on the telephone less than once a month. ��Only 23 per cent of the general public thought it was possible for a person with dementia to live alone ��16 per cent answered that they would not be comfortable talking to someone with dementia, 19 per cent were unsure.The findings from Dementia 2013 are based on a survey of 510 people with dementia or carers on their behalf and a YouGov poll of 2,287 UK adults.Download the full report here.������

Northern Ireland Point Prevalence Survey of Hospital-acquired Infections and Antimicrobial Use 2012

The PHA�coordinated Northern Ireland's participation in ECDC's National Prevalence Survey on�Hospital-Acquired Infections & on Antimicrobial Use. Hospitals in Northern Ireland participated in data collection between May and June 2012.This report provides a snapshot of the levels of hospital-acquired infections (HAI) and levels of antimicrobial use (AMU) in hospitals in Northern Ireland during 2012.There have been three previous HAI PPS surveys and the last survey was carried out in 2006. It is difficult to compare each survey as the data was collected in a different way. However, after making allowances, there was an overall drop in HAI prevalence of 18% from 2006 to 2012.The PPS data collection was undertaken by hospital teams between May and June 2012 (one hospital deferred data collection until September 2012 because of a move to a new hospital); 16 hospitals surveyed 3,992 eligible patients. The median age of all patients was 66 years. A total of 383 (10 per cent) children under 16 years of age were surveyed.�Key results from this year's survey:The prevalence of HAI was 4.2%. A total of 166 patients were diagnosed with an active HAI with 3 patients having more than one infection.When comparing ward specialties, HAI prevalence was highest for patients in adult intensive care units (ICUs) at 9.1 per cent, followed by care of the elderly wards at 5.7%.The most common types of HCAI were respiratory infections (including pneumonia and infections of the lower respiratory tract) (27.9 per cent of all infections), surgical site infections (18.9 per cent) and urinary tract infections (UTI) (11.8 per cent).Since the last PPS in 2006 there has been a reduction in MRSA infections - from 0.9 per cent �of the hospital population to less than 0.1 per cent in patients; and a five-fold reduction in C. difficile infections (from 1.1 per cent to 0.2 per cent).The prevalence of antimicrobial use was 29.5%.Most antibiotic use (60 per cent) in hospitals was in patients receiving treatment for infections which commenced in the community. Eleven percent of surgical prophylaxis was prescribed for greater than one day.��

English as a world language: its role as a lingua francaa sociolinguistic profile of students of secondary schools in Santiago Island, in the Archipelago of Cape Verde

Esta tese centra-se em aspectos relevantes do inglês como uma língua universal, no actual contexto globalizado e examina possíveis mudanças relacionadas com o seu uso, em especial no continente africano, particularmente no caso de Cabo Verde, no sentido de ponderar eventuais alternativas nas pedagogias linguísticas no ensino desta língua que impliquem uma adaptação à realidade contemporânea. Uma vez que, nos nossos tempos, o inglês é a língua de eleição para a comunicação intercultural entre povos com várias experiências culturais e linguísticas, o conhecimento deste idioma torna-se, a cada dia que passa, impreterível e indispensável, na interacção intercultural. Em África, as funções desempenhadas pelo inglês são complexas; além da língua inglesa ser usada para comunicação entre etnias, com o estatuto de língua franca, também tem o papel de preservar a identidade nacional e de estabelecer a unidade entre os povos da mesma nação. Por conseguinte, é de considerar talvez ainda com mais pertinência, a adopção de uma nova filosofia de pedagogia de ensino que permita dotar os seus cidadãos de capacidades que lhes possibilitem comunicar de forma inteligível com povos de outras culturas e línguas. O primeiro capítulo aborda aspectos teóricos relacionados com a expansão, comunicação e mudança associadas à língua inglesa e suas implicações no ensino em países onde esta não é língua nativa (L1). O segundo capítulo reflecte, em primeiro lugar, sobre a situação linguística em África e as línguas francas predominantes no continente, incluindo a língua inglesa. Considera também questões relacionadas com o multilinguismo e a identidade, bem como assuntos relacionados com as implicações da diversidade linguística para a educação dos povos africanos.

Simultaneous determination of Pu and Am radioisotopes in environmental samples: a tool for determining origin and release date

A radiochemical procedure was developed for the sequential determination of Pu and Am radioisotopes in environmental samples. The radioisotope activities were then used to assess the origin and release date of the environmental plutonium. The radioanalytical procedure is based on the separation of Pu and Am on selective extraction chromatographic resins (Eichrom TEVA and DGA). Alpha sources were prepared by electrodeposition on stainless steel discs, and the alpha emitting radionuclides (238Pu, 239,240Pu and 241Am) were measured by alpha spectrometry. For the determination of the beta emitting 241Pu, the Pu alpha source was leached in hot concentrated nitric acid and the Pu fraction further purified by extraction chromatography on a small column of TEVA resin (100 μg of resin in a pipette tip). 241Pu is then measured by ultra low level liquid scintillation counting. Due to the lack of reference material for 241Pu, the proposed radiochemical method was nevertheless validated using four IAEA reference sediments with information values of 241Pu. The proposed method was then used to determine the 238Pu, 239,240Pu, 241Pu and 241Am activity concentrations in alpine soils of France and Switzerland. The soil is the primary receptor of the atmospheric radioactive fallout and, because of the strong binding interaction with soils particles, the isotopes are little fractionated. Therefore, the activity ratios 241Pu/239+240Pu and 238Pu/239,240Pu in soil samples were used to determine the origin (source) and date of the Pu contamination in the investigated alpine sites. The 241Pu/239,240Pu and 238Pu/239,240Pu activity ratios confirmed that the main origin of Pu in the alpine soils was the global fallout from the nuclear bomb tests (NBT) in the fifties and sixties. Furthermore, the 241Pu/241Am activity ratios were used to determine the age of the Pu contamination, which is also an important data for distinguishing the Pu sources. The estimation of the date of the contamination, by the 241Pu/241Am age-dating method, further confirmed the NBT as the Pu source. However, the 241Pu/241Am dating method was limited to samples where Pu-Am fractionation was insignificant. If any, the contribution of the Chernobyl accident in the studied sites is negligible.

Dosimetry of 90Y-ibritumomab tiuxetan as consolidation of first remission in advanced-stage follicular lymphoma: results from the international phase 3 first-line indolent trial.

The objective of this analysis was to assess the radiation exposure associated with (90)Y-ibritumomab tiuxetan when used as consolidation therapy in adults with low or minimal tumor burden after first-line therapy of advanced follicular lymphoma (FL). METHODS: The patients who were enrolled in the phase 3 first-line indolent trial were 18 y or older, with CD20(+) grade 1 or 2 stage III or IV FL, and a partial response, complete response, or unconfirmed complete response to first-line chemotherapy. The patients were allocated randomly to receive a single infusion of unlabeled rituximab 250 mg/m(2) on day -7 and consolidation on day 0 with a single dose of (90)Y-ibritumomab tiuxetan, 14.8 MBq/kg, immediately after unlabeled rituximab, 250 mg/m(2), or no further treatment. On day -7, a subset of patients received an injection of 185 MBq of (111)In-ibritumomab tiuxetan immediately after unlabeled rituximab, 250 mg/m(2), for central dosimetry analysis. Correlations were assessed between organ radiation absorbed dose and toxicity, body weight, body mass index, and progression-free survival. RESULTS: Central dosimetry evaluations were available from 57 of 70 patients. Median radiation absorbed doses were 100 cGy (range, 28-327 cGy) for the red marrow and 72 cGy (range, 46-106 cGy) for the whole body. Radiation absorbed doses did not differ significantly between patients who had a partial response or complete response to initial therapy. Progression-free survival correlated significantly with the whole-body (r = 0.4401; P = 0.0006) and bone marrow (r = 0.2976; P = 0.0246) radiation dose. Body weight was significantly negatively correlated with whole-body radiation dose (r = -0.4971; P < 0.0001). Neither the whole-body radiation dose nor the bone marrow radiation dose correlated with hematologic toxicity. CONCLUSION: In patients with low or minimal residual tumor burden after first-line chemotherapy of advanced FL, whole-body and bone marrow exposure after (90)Y-ibritumomab tiuxetan consolidation showed a significant positive correlation with progression-free survival, whereas dosimetric data could not predict hematologic toxicity.

Non-Grouted Bonded PCC Overlay City of Oskaloosa, HR-528, 1993

Based upon the success the Iowa Department of Transportation has had using thin bonded, low slump, dense portland cement concrete on bridge decks for rehabilitation, it was decided to pursue research in the area of bonded portland cement concrete resurfacing of pavements. Since that time, in an effort to reduce costs, research was conducted into eliminating the grouting operation. On this project a non-grouted overlay was used to modernize an existing urban street. This research project is located in the City of Oskaloosa on 11th Avenue from South M Street to South Market Street. Construction of the project went well and the non-grouted overlay has performed very well to date.

Service Correlation of the Traffic Simulator, HR-100, 1967

A study was undertaken by the Bituminous Research Laboratory of the Engineering Research Institute at Iowa State University, under the sponsorship of the Iowa Highway Research Board, project HR 100, to ascertain the effects of a number of characteristics and properties of asphaltic concrete mixes upon the service behavior of the mixes as evaluated by the Traffic Simulator and by field observations. The study included: Investigations of the relations, of gradation, fraction and resistance to wear of aggregates; of stability, cohesion, per cent voids and asphalt content: of a number of laboratory and field mixes to service behavior as indicated by the Traffic Simulator under various test conditions. Based upon the results of the tests and the relationships noted, tentative criteria for the Traffic Simulator test were devised, subject to verification by observations and measurements of field service behavior of the mixes.

Phenotypic and functional analysis of human fetal liver hematopoietic stem cells in culture.

Steady-state hematopoiesis and hematopoietic transplantation rely on the unique potential of stem cells to undergo both self-renewal and multilineage differentiation. Fetal liver (FL) represents a promising alternative source of hematopoietic stem cells (HSCs), but limited by the total cell number obtained in a typical harvest. We reported that human FL nonobese diabetic/severe combined immunodeficient (NOD/SCID) repopulating cells (SRCs) could be expanded under simple stroma-free culture conditions. Here, we sought to further characterize FL HSC/SRCs phenotypically and functionally before and following culture. Unexpanded or cultured FL cell suspensions were separated into various subpopulations. These were tested for long-term culture potential and for in vivo repopulating function following transplantation into NOD/SCID mice. We found that upon culture of human FL cells, a tight association between classical stem cell phenotypes, such as CD34(+) /CD38(-) and/or side population, and NOD/SCID repopulating function was lost, as observed with other sources. Although SRC activity before and following culture consistently correlated with the presence of a CD34(+) cell population, we provide evidence that, contrary to umbilical cord blood and adult sources, stem cells present in both CD34(+) and CD34(-) FL populations can sustain long-term hematopoietic cultures. Furthermore, upon additional culture, CD34-depleted cell suspensions, devoid of SRCs, regenerated a population of CD34(+) cells possessing SRC function. Our studies suggest that compared to neonatal and adult sources, the phenotypical characteristics of putative human FL HSCs may be less strictly defined, and reinforce the accumulated evidence that human FL represents a unique, valuable alternative and highly proliferative source of HSCs for clinical applications.

Analyzing hydraulic head of fluid flow in underground porous medium

Hydraulic head is distributed through a medium with porous aspect. The analysis of hydraulic head from one point to another is used by the Richard's equation. This equation is equivalent to the groundwater ow equation that predicts the volumetric water contents. COMSOL 3.5 is used for computation applying Richard's equation. A rectangle of 100 meters of length and 10 meters of large (depth) with 0,1 m/s fl ux of inlet as source of our fl uid is simulated. The domain have Richards' equation model in two dimension (2D). Hydraulic head increases proportional with moisture content.
