Rocket motor exhaust products generated by the space shuttle vehicle during its launch phase (1976 design data)

The principal chemical species emitted and/or entrained by the rocket motors of the space shuttle vehicle during the launch phase of its trajectory are considered. Results are presented for two extreme trajectories, both of which were calculated in 1976

Leeds Free School Meals Research Project (Phase 2 Report: Findings from the pilot phase Leeds Metropolitan University)

Free school meals aim to provide a “nutritional safety net” for the poorest UK children. Yet it is estimated that up to 30% of those entitled do not take up this entitlement. In Leeds approximately 6,000 children do not take the free school meals that they are entitled to. National and local targets are for 100% take up. Phase 2 of the Leeds Free School Meal Research Project aimed to develop, implement and evaluate a series of interventions to increase the uptake of free school meals. The interventions were tested in ten Leeds schools between December 2007 and October 2008. The research was undertaken by the Department of Nutrition & Dietetics within The Centre of Food Nutrition and Health at Leeds Metropolitan University on behalf of Education Leeds

Worldwide satellite market demand forecast

The forecast is for the years 1981 - 2000 with benchmark years at 1985, 1990 and 2000. Two typs of markets are considered for this study: Hardware (worldwide total) - satellites, earth stations and control facilities (includes replacements and spares); and non-hardware (addressable by U.S. industry) - planning, launch, turnkey systems and operations. These markets were examined for the INTELSAT System (international systems and domestic and regional systems using leased transponders) and domestic and regional systems. Forecasts were determined for six worldwide regions encompassing 185 countries using actual costs for existing equipment and engineering estimates of costs for advanced systems. Most likely (conservative growth rate estimates) and optimistic (mid range growth rate estimates) scenarios were employed for arriving at the forecasts which are presented in constant 1980 U.S. dollars. The worldwide satellite market demand forecast predicts that the market between 181 and 2000 will range from $35 to$50 billion. Approximately one-half of the world market, $16 to$20 billion, will be generated in the United States

The socio-economic status of women in central Sudan

Sexual inequality is rooted in many early histories and cultures and has often been compounded by a modernisation process imposed from the West which has progressively lowered the status of women since benefits have accrued mainly to the male sector of society. In the developing world where general living conditions are poor and the impact of development programmes most profound, the male/female differential of opportunity and expectation is consequently widening and the conditions of women's lives becoming increasingly restrictive. In Central Sudan the level of socio-economic development is low by global standards. The particular sociocultural and socioeconomic characteristics of the population must be taken into account when attempting to describe and explain the status of women in the region. In Central Sudan, Islam is of fundamental significance because of its influence on the male/female differential in general and because the religious orientation of the population influenced the effects of development planning in this region on the lives and status of women. Central Sudan is the home of Sudan's largest development project - the Gezira Irrigation Scheme. The influence of the Scheme is investigated here using a questionnaire-based research approach and seven sample villages. These villages are situated in areas which have been involved in the Scheme for differing lengths of time - sixty, thirty and ten years. This provided a crude representation of the temporal changes in socioeconomic conditions which are attributable to the influence of the Scheme. The Gezira Scheme has intervened in the process of change over an extensive geographical and social area involving the inhabitants of the area and migrant peoples from outside. Most indigenous households received tenancies but many Western Sudanese and non-nationals, particularly Nigerians, were attracted to the Scheme as wage-labourers

Oral health awareness and care preferences in patients with diabetes : a qualitative study

Background People with type 2 diabetes have an increased risk of oral health problems; however, oral health is currently not included in structured diabetes reviews and education in the UK. Aim and Objectives This study explores the patient experience related to oral health and diabetes, especially in relation to: • Awareness of the link between oral health and diabetes and oral self care needs • Interaction with health professionals in dental and general practice • Preferences for receiving oral health information and education Methods This nested qualitative study involved semi-structured telephone interviews with a purposive sample of 20 participants from a questionnaire study on oral health awareness in patients with diabetes. Interview transcripts were analysed using a thematic framework approach. Results Participants were mostly unaware of the link between oral health and diabetes. Those that had been made aware by a health professional were not given concrete self care advice. Interactions with dental professionals were often limited to informing the dental practice of their diagnosis and current medication. Most participants were in favour of dentists screening for diabetes, but as their general practice was the hub for diabetes care, they felt GPs or nurses should provide oral health information and discuss oral health with patients. Conclusions Written information regarding diabetes and its possible effects on oral health needs to be more readily available to people with diabetes, especially at diagnosis. There may be a place for introducing a structured oral health question in routine diabetes reviews
