Influence of inter-electrode distance, contraction type, and muscle on the relationship between the sEMG power spectrum and contraction force.

INTRODUCTION: Spectral frequencies of the surface electromyogram (sEMG) increase with contraction force, but debate still exists on whether this increase is affected by various methodological and anatomical factors. This study aimed to investigate the influence of inter-electrode distance (IED) and contraction modality (step-wise vs. ramp) on the changes in spectral frequencies with increasing contraction strength for the vastus lateralis (VL) and vastus medialis (VM) muscles. METHODS: Twenty healthy male volunteers were assessed for isometric sEMG activity of the VM and VL, with the knee at 90° flexion. Subjects performed isometric ramp contractions in knee extension (6-s duration) with the force gradually increasing from 0 to 80 % MVC. Also, subjects performed 4-s step-wise isometric contractions at 10, 20, 30, 40, 50, 60, 70, and 80 % MVC. Interference sEMG signals were recorded simultaneously at different IEDs: 10, 20, 30, and 50 mm. The mean (F mean) and median (F median) frequencies and root mean square (RMS) of sEMG signals were calculated. RESULTS: For all IEDs, contraction modalities, and muscles tested, spectral frequencies increased significantly with increasing level of force up to 50-60 % MVC force. Spectral indexes increased systematically as IED was decreased. The sensitivity of spectral frequencies to changes in contraction force was independent of IED. The behaviour of spectral indexes with increasing contraction force was similar for step-wise and ramp contractions. CONCLUSIONS: In the VL and VM muscles, it is highly unlikely that a particular inter-electrode distance or contraction modality could have prevented the observation of the full extent of the increase in spectral frequencies with increasing force level.

Biocontrol by phenazine-1-carboxamide-producing Pseudomonas chlororaphis PCL1391of tomato root rot caused by Fusarium oxysporum f. sp. radicis-lycopersici

Seventy bacterial isolates from the rhizosphere of tomato were screened for antagonistic activity against the tomato foot and root rot-causing fungal pathogen Fusarium oxysporum f. sp. radicis-lycopersici. One isolate, strain PCL1391, appeared to be an efficient colonizer of tomato roots and an excellent biocontrol strain in an F. oxysporum/tomato test system. Strain PCL1391 was identified as Pseudomonas chlororaphis and further characterization showed that it produces a broad spectrum of antifungal factors (AFFs), including a hydrophobic compound, hydrogen cyanide, chitinase(s), and protease(s). Through mass spectrometry and nuclear magnetic resonance, the hydrophobic compound was identified as phenazine-1-carboxamide (PCN). We have studied the production and action of this AFF both in vitro and in vivo. Using a PCL1391 transposon mutant, with a lux reporter gene inserted in the phenazine biosynthetic operon (phz), we showed that this phenazine biosynthetic mutant was substantially decreased in both in vitro antifungal activity and biocontrol activity. Moreover, with the same mutant it was shown that the phz biosynthetic operon is expressed in the tomato rhizosphere. Comparison of the biocontrol activity of the PCN-producing strain PCL1391 with those of phenazine-1-carboxylic acid (PCA)-producing strains P. fluorescens 2-79 and P. aureofaciens 30-84 showed that the PCN-producing strain is able to suppress disease in the tomato/F. oxysporum system, whereas the PCA-producing strains are not. Comparison of in vitro antifungal activity of PCN and PCA showed that the antifungal activity of PCN was at least 10 times higher at neutral pH, suggesting that this may contribute to the superior biocontrol performance of strain PCL1391 in the tomato/F. oxysporum system.

Planning Practice Guidance

The Department for Communities and Local Government has published National Planning Practice Guidance which recognises the importance of local infrastructure planning in the development of healthy communities. The guidance supports the National Planning Policy Framework and now includes a section on health and wellbeing. This guidance sets out the government’s planning policies for England and how these are expected to be applied by local authorities. A significant development in the guidance is the recognition of the important role the planning system can play in facilitating social interaction and creating healthy, inclusive communities. Local planning authorities should ensure that health and wellbeing, and health infrastructure are considered in local and neighbourhood plans and in planning decision making.

National Health and Lifestyle Surveys

Results of the National Health and Lifestyle Surveys: SLaN [Survey of Lifestyle, Attitudes and Nutrition] and HBSC [Health Behaviour in School-Aged Children] Two baseline surveys of health related behaviours among adults and schoolgoing young people were carried out across the Republic of Ireland in 1998 and again in 2002. The main aims of these surveys are to: - Produce reliable data of a representative cross-section of the Irish population in order to inform the Department of Health and Children's policy and programme planning. - Maintain a survey protocol which will enable lifestyle factors to be remeasured so that trends can be identified and changes monitored to assist national and regional setting of priorities in health promotion activities. In keeping with the health and lifestyle surveillance system of many European countries a number of related factors were measured in both surveys. These include general health, smoking, use of alcohol and other substances, food and nutrition, exercise and accidents. This work was commissioned by the Health Promotion Unit, Department of Health and Children and carried out at the Centre for Health Promotion Studies, National University of Ireland, Galway.This resource was contributed by The National Documentation Centre on Drug Use.

National Health and Lifestyle Surveys. Regional Summary Report (2003)

Two baseline surveys of health related behaviours among adults and school-going young people were carried out across the Republic of Ireland in 1998 and again in 2002. The main aims of these surveys are to: - Produce reliable data of a nationally representative cross-section of the Irish population in order to inform the Department of health and Children's policy and programme planning. - Maintain a survey protocol which will enable lifestyle factors to be re-measured so that trends can be identified and changes monitored to assist national and regional setting of priorities in health promotion activities. This report focuses on these two cross-sectional studies, SLaN (Survey of Lifestyles, Attitudes and Nutrition) adults aged 18+ years and HBSC (health Behaviour in School-aged Children) school-going children aged 10-17 years. In keeping with the health and lifestyle surveillance system of many European countries a number of related factors were measured in both surveys. These include general health, smoking, use of alcohol and other substances, food and nutrition, exercise and accidents. This report presents the findings for the same topics at a regional level with some demographic analysis. It must be noted that the aim of the survey was to establish patterns in health and lifestyle at a national level. The significance therefore of findings at the regional level is to identify potential variations that may merit further investigation. This work was commissioned by the health Promotion Unit, Department of health and Children and carried out at the Centre for health Promotion Studies, national University of Ireland, Galway, and at the Department of Public health Medicine and Epidemiology, Woodview House, Belfield, national University of Ireland, Dublin.This resource was contributed by The National Documentation Centre on Drug Use.

Clustering and hot spot detection in socio-economic spatio-temporal data

Distribution of socio-economic features in urban space is an important source of information for land and transportation planning. The metropolization phenomenon has changed the distribution of types of professions in space and has given birth to different spatial patterns that the urban planner must know in order to plan a sustainable city. Such distributions can be discovered by statistical and learning algorithms through different methods. In this paper, an unsupervised classification method and a cluster detection method are discussed and applied to analyze the socio-economic structure of Switzerland. The unsupervised classification method, based on Ward's classification and self-organized maps, is used to classify the municipalities of the country and allows to reduce a highly-dimensional input information to interpret the socio-economic landscape. The cluster detection method, the spatial scan statistics, is used in a more specific manner in order to detect hot spots of certain types of service activities. The method is applied to the distribution services in the agglomeration of Lausanne. Results show the emergence of new centralities and can be analyzed in both transportation and social terms.

Revised Criteria and Procedures for the Establishment of New Primary Schools - Report of the Commission on School Accommodation

Part One explores the background factors relating to new school establishment, outlines the views received as a result of consultation with the public and the New Schools Advisory Committee (NSAC) and reviews international practice in relation to establishment of new schools. The population of the country experienced an unprecedented increase in the past ten years. Despite the current economic downturn, the effect of this recent population increase is that growth in demand for school places is set to increase over the short to medium term. The overriding objective is to ensure that a school place is available to every child. Part Two explores issues around planning for new schools in the future. It discusses patron selection, the mechanism for identifying the need for a new school and proposals for cost effectiveness, including campus arrangements. A school is of central importance to a local community and therefore the establishment of a new school must be carried out with reference to the overall plan of the local authority for any given area. Guidelines published under Section 28 of the Planning Act entitled “The Provision of Schools and the Planning System” (July 2008) establish a 7 framework for co-operation between the Department and planning authorities to ensure the timely and cost-effective provision of school facilities.

Map of ecological networks for landscape planning

This paper presents a method based on a geographical information system (GIS) to model ecological networks in a fragmented landscape. The ecological networks are generated with the help of a landscape model (which integrate human activities) and with a wildlife dispersal model. The main results are maps which permit the analysis and the understanding of the impact of human activities on wildlife dispersal. Three applications in a study area are presented: ecological networks at the landscape scale, conflicting areas at the farmstead scale and ecological distance between biotopes. These applications show the flexibility of the model and its potential to give information on ecological networks at different planning scales.

Ross procedure: is the root replacement technique superior to the sub-coronary implantation technique? Long-term results.

There is controversy over the use of the Ross procedure with regard to the sub-coronary and root replacement technique and its long-term durability. A systematic review of the literature may provide insight into the outcomes of these two surgical subvariants. A systematic review of reports between 1967 and February 2013 on sub-coronary and root replacement Ross procedures was undertaken. Twenty-four articles were included and divided into (i) sub-coronary technique and (ii) root replacement technique. The 10-year survival rate for a mixed-patient population in the sub-coronary procedure was 87.3% with a 95% confidence interval (CI) of 79.7-93.4 and 89.1% (95% CI, 85.3-92.1) in the root replacement technique category. For adults, it was 94 vs 95.3% (CI, 88.9-98.1) and in the paediatric series it was 90 vs 92.7% (CI, 86.9-96.0), respectively. Freedom from reoperation at 10 years was, in the mixed population, 83.3% (95% CI, 69.9-93.4) and 93.3% (95% CI, 89.4-95.9) for sub-coronary versus root replacement technique, respectively. In adults, it was 98 vs 91.2% (95% CI, 82.4-295.8), and in the paediatric series 93.3 vs 92.0% (95% CI, 86.1-96.5) for sub-coronary versus root replacement technique, respectively. The Ross procedure arguably has satisfactory results over 5 and 10 years for both adults and children. The results do not support the advantages of the sub-coronary technique over the root replacement technique. Root replacement was of benefit to patients undergoing reoperations on neoaorta and for long-term survival in mixed series.
