An Integrated Content and Metadata based Retrieval System for Art

In this paper we describe aspects of the Artiste project to develop a distributed content and metadata based analysis, retrieval and navigation system for a number of major European Museums. In particular, after a brief overview of the complete system, we describe the design and evaluation of some of the image analysis algorithms developed to meet the specific requirements of the users from the museums. These include a method for retrievals based on sub images, retrievals based on very low quality images and retrieval using craquelure type

Meal size is a critical driver of weight gain in early childhood

Larger serving sizes and more frequent eating episodes have been implicated in the rising prevalence of obesity at a population level. This study examines the relative contributions of meal size and frequency to weight gain in a large sample of British children. Using 3-day diet diaries from 1939 children aged 21 months from the Gemini twin cohort, we assessed prospective associations between meal size, meal frequency and weight gain from two to five years. Separate longitudinal analyses demonstrated that every 10 kcal increase in meal size was associated with 1.5 g/wk or 4% (p = 0.005) faster growth rate, while meal frequency was not independently associated with growth (β = 0.3 g/wk p = 0.20). Including both meal parameters in the model strengthened associations (meal size: β = 2.6 g/wk, p < 0.001; meal frequency: β = 1.0 g/wk, p = 0.001). Taken together, the implication is that meal size promotes faster growth regardless of frequency, but meal frequency has a significant effect only if meal size is assumed to be held constant. Clearer advice on meal size and frequency, especially advice on appropriate meal size, may help prevent excess weight gain

Caractérisation Physico-Chimique Et Étude De La Toxicité De La Lagune Côtière, De Togbin À GrandPopo (Sud-Ouest Bénin)

This work deals with the physicochemical characterization and the toxicity study of the coastal lagoon of Benin (from Togbin to Grand-Popo). In particular, it has to do with the study of copper and zinc. The sampling campaign was carried out by motorized boat on the 20th of December 2016. Samples were taken a few centimeters below the surface of the water. The analysis of the metals was carried out with a HACH LANGE DR2800 spectrophotometer. Copper is determined by the method of Bicinchroninate, while zinc is determined by the method of Zincover. The method used for the toxicity study is natural and is based on the inoculation of onions in the waters sampled at various proportions. The results revealed that physically and chemically, the lagoon is highly mineralized. This mineralization is due not only to the contribution of the sea to high tide, but also to salt production in Djègbadji. Concerning the concentrations of trace metallic elements, copper and zinc do not pose a risk to humans, but pose a high risk to the aquatic organisms present in the lagoon. Potentially suspected sources of copper and zinc are Ahémé Lake and the Mono River. As for the ecotoxicological study with the Allium cepa test, this test is not only influenced by metals, but also by the salinity of the water. The test revealed that the waters of the lagoon are acutely toxic, particularly at Djondji. Strategies for the protection and rehabilitation of the coastal lagoon must be undertaken by decision-makers at all levels. This, therefore, will help to prevent not only the different populations from the risks of diseases, but also increase the economy of the country through marketing and the edibility of the fish and even offer a framework of tourist scale

Mycobacterium avium subsp. paratuberculosis Virulence: A Review

To propose a solution for control of Mycobacterium avium subsp. paratuberculosis (MAP) infections in animals as well as in humans, and develop effective prevention, diagnostic and treatment strategies, it is essential to understand the molecular mechanisms of MAP pathogenesis. In the present review, we discuss the mechanisms utilised by MAP to overcome the host defense system to achieve the virulence status. Putative MAP virulence genes are mentioned and their probable roles in view of other mycobacteria are discussed. This review provides information on MAP strain diversity, putative MAP virulence factors and highlights the knowledge gaps regarding MAP virulence mechanisms that may be important in control and prevention of paratuberculosis

A qualitative exploration of school-based staff's experiences of delivering an alcohol screening and brief intervention in the high school setting: findings from the SIPS JR-HIGH trial.

Background: Whilst underage drinking in the UK has been declining in recent years, prevalence is still higher than in most other Western European countries. Therefore, it is important to deliver effective interventions to reduce risk of harm. Methods: Semi-structured interviews with staff delivering an alcohol screening and brief intervention in the high-school setting. The analysis was informed by normalization process theory (NPT), interviews were open coded and then a framework applied based on the four components of NPT. Results: Five major themes emerged from the analysis. The majority of participants felt that the intervention could be useful, and that learning mentors were ideally suited to deliver it. However, there was a feeling that the intervention should have been targeted at young people who drink the most. Conclusions: The intervention was generally well received in schools and seen as an effective tool for engaging young people in a discussion around alcohol. However, in the future schools need to consider the level of staffing in place to deliver the intervention. Furthermore, the intervention could focus more on the long-term risks of initiating alcohol consumption at a young age

Eliciting and prioritising determinants of improved care in multimorbidity: A modified online Delphi study.

BACKGROUND: Multimorbidity is a major challenge to health and social care systems around the world. There is limited research exploring the wider contextual determinants that are important to improving care for this cohort. In this study, we aimed to elicit and prioritise determinants of improved care in people with multiple conditions. METHODS: A three-round online Delphi study was conducted in England with health and social care professionals, data scientists, researchers, people living with multimorbidity and their carers. RESULTS: Our findings suggest a care system which is still predominantly single condition focused. 'Person-centred and holistic care' and 'coordinated and joined up care', were highly rated determinants in relation to improved care for multimorbidity. We further identified a range of non-medical determinants that are important to providing holistic care for this cohort. CONCLUSIONS: Further progress towards a holistic and patient-centred model is needed to ensure that care more effectively addresses the complex range of medical and non-medical needs of people living with multimorbidity. This requires a move from a single condition focused biomedical model to a person-based biopsychosocial approach, which has yet to be achieved

Test Bench Of The Barrel Calorimeter Modules

A systematic procedure to qualify the barrel calorimeter modules is an essential step to guarantee a 0.7% constant term, which is the collaboration objective. The procedure detailed in this note consists of quality monitoring during mechanical assembling and of a set of electrical tests such as electrical continuity, cell and cross-talk capacitance measurement, and high-voltage behaviour. For the whole test, it has been necessary to develop dedicated electronic boards, to develop measurement methods, and the whole operation software. Making the procedure automatic will guarantee the quality of each module during assembling, cabling, and test in liquid argon

A qualitative account of young people's experiences of alcohol screening and brief interventions in schools: SIPS Jr-HIGH trial findings.

BACKGROUND: The United Kingdom (UK) has seen a decrease in the number of young people drinking alcohol. However, the UK prevalence of underage drinking still ranks amongst the highest in Western Europe. Whilst there is a wealth of evidence reporting on the effectiveness of both primary, and secondary interventions, there are few reports of the experiences of young people who receive them. METHODS: The present study reports findings from interviews with 33 young people who were involved in an alcohol screening and brief intervention randomized controlled trial in schools in England. All interviews were analysed using inductive applied thematic analysis. RESULTS: Three major themes were identified following the analysis process: 1) drinking identities and awareness of risk; 2) access to support and advice in relation to alcohol use; and 3) appraisal of the intervention and potential impact on alcohol use. CONCLUSIONS: There appeared to be a reluctance from participants to describe themselves as someone who drinks alcohol. Furthermore, those who did drink alcohol often did so with parental permission. There was variation amongst participants as to how comfortable they felt talking about alcohol issues with school staff. Overall participants felt the intervention was useful, but would be better suited to 'heavier' drinkers
