Helical automatic approaches of helicopters with microwave landing systems

A program is under way to develop a data base for establishing navigation and guidance concepts for all-weather operation of rotorcraft. One of the objectives is to examine the feasibility of conducting simultaneous rotorcraft and conventional fixed-wing, noninterfering, landing operations in instrument meteorological conditions at airports equipped with microwave landing systems (MLSs) for fixed-wing traffic. An initial test program to investigate the feasibility of conducting automatic helical approaches was completed, using the MLS at Crows Landing near Ames. These tests were flown on board a UH-1H helicopter equipped with a digital automatic landing system. A total of 48 automatic approaches and landings were flown along a two-turn helical descent, tangent to the centerline of the MLS-equipped runway to determine helical light performance and to provide a data base for comparison with future flights for which the helical approach path will be located near the edge of the MLS coverage. In addition, 13 straight-in approaches were conducted. The performance with varying levels of state-estimation system sophistication was evaluated as part of the flight tests. The results indicate that helical approaches to MLS-equipped runways are feasible for rotorcraft and that the best position accuracy was obtained using the Kalman-filter state-estimation with inertial navigation systems sensors

SmokeFree Sports Project Report

Children and young people are amongst the most vulnerable groups in society and are highly susceptible to smoking experimentation and addiction. In Liverpool, smoking prevalence is significantly higher than the UK average. Therefore early intervention strategies are required for smoking prevention and cessation. Research has found a negative association between smoking and physical activity. SmokeFree Sports aims to explore whether physical activity and sport can be used to promote the smoke free message to children and young people. SmokeFree Sports is an innovative multi-dimensional campaign that incorporates social-marketing strategies alongside the provision of sports and physical activities to: a) de-normalise smoking among youth b) empower youth to stay smoke free, and c) increase awareness of the dangers of smoking using positive messaging through the medium of sport and physical activity. This project is delivered across Liverpool and aims to reduce the prevalence of smoking and prevent the uptake of smoking in children and young people. The initiative, which is managed by Liverpool John Moores University in partnership with Liverpool PCT, employs a variety of strategies to promote and deliver the smoke free message to children and young people including a) training sports coaches and teachers to deliver the smoke free message, b) delivering SFS messages in schools and youth clubs through sport and physical activity, c) asking children to sign a pledge to be smoke free, d) support voluntary sports clubs to adopt a smoke free policy on their playing fields, e) encouraging organizations and individuals interested in health and sport to sign up to the SmokeFree Sports Charter and f) signposting children to smoking cessation services

Erratum: Is it possible to infer the equation of state of a mixture of hard discs from that of the one-component system?

The numerical values in the sixth and seventh columns of table 1 of the paper Molec. Phys., 1999, 96, 1185-1188 are not correct. Consequently, some of the comments made in the paper are wrong. The corrected version of table 1 is reprinted here and the results are briefly discussed.Comment: 2 pages; Erratum to Molec. Phys., 1999, 96, 1185-1188; to be published in Molec. Phy

Living Out Faith: Reflections on Motivation for Academic Achievement and Career Choice

It has often been said that conversations concerning religion, sex and politics should be avoided in most, if not all social settings. In general, it was believed that discussions on these topics could lead to very heated and argumentative debates as the participants openly expressed their views on these subjects. Increasingly, however, religion has become a popular discussion topic in many areas, such as politics, health and medicine, and even the business world. This is likely because religion, for many, is an important part of daily life. It shapes how individuals see themselves and others in the world and may even help to guide life decisions. Because of its importance in many people’s lives, religion and faith and spirituality (which are often used interchangeably with religion), deserves further investigation. This study attempted to explore the relationship between faith and education as well as examined the possibility that one’s faith may influence academic achievement and career choice. The research questions that guided this research were: How is faith defined by individuals whose religious beliefs and practices differ across religious denominations? How does ones’ conception of faith influence academic and career aspirations and/or choices? This study utilized the research method of narrative inquiry and using three semi-structured interviews with participants from five different religious denominations namely, Buddhist, Christian, Hindu (Jain), Jewish and Muslim. The research results were examined through two lenses: Self-Determination Theory and The Theory of the “U”. The four themes that emerged were Faith within the Family; Faith Choice; Faith with Academics and Career Choice; and Faith in Service to Others

Artificial Teeth for Permanent Implantation

Artificial teeth with a low solubility and with properties similar to natural teeth were produced for implantation tests. The teeth were made from MgAl2O4 spinel and Ca3(PO4)2 Whitlockite to achieve low solubility and non-toxic reaction products. The method of manufacture is described
