Design And Production

Mega-Floating Airports (MFA) are unique and complex offshore transport system components that emerged as a consequence of tremendous land price increase in the vicinity of very large coastal cities. An overview of MFAs design and production aspects is presented within this paper including design concept, model tests and full scale measurement, air transport analysis, infrastructure, main particulars and structure, wave breaker, hydroelastic analysis due to wave load and airplane moving mass, mooring analysis, production technology and environmental aspects. MFA dynamic response due to airplane load is emphasized as the most challenging problem. Theoretical outline as well as a realistic illustrative numerical example are presented.

This paper analyses the scientific study on airport efficiency in the WoS (Web of Science) database for the period 2000–2019. Productivity indicators have been obtained by author, years, journals, and institutions, and an analysis of visibility, impact, and scientific collaboration through co-citations was performed. The areas of greatest application are transport, engineering, and economics. This study reveals the existence of three research lines, one on airport safety and management, another on technical efficiency using mainly the DEA method, and the third associated with airport regularization issues. An important issue which is increasingly taken into account in efficiency studies is related to environmental aspects. In the ranking of journals publishing on airport efficiency, ordered by number of articles indexed in WoS, Journal of Air Transport Management is the one with the highest number of cited articles and publications, whereas Sustainability stands out as the first non-specific journal on transport. The University of Lisbon and the University of British Columbia are the ones that deal most with airport efficiency.

An All-Day Symposium on Cheap Short-Range Air Transport was held by the Society in the Lecture Theatre on 4th May 1965. The Chair was taken by Professor M. J. Lighthill, DSc, FRS, FRAeS, Hon FAIAA. Five short papers were given: Some Factors Affecting Fares, A. L. Courtney, RAE, Farnborough; An Airline View, R. H. Whitby, BSc, ARCS, D1C, FRAeS, BEA; Steps Towards Lower Operating Costs with Conventional Jet Transports, C. J. Hamshaw Thomas, MA, AFRAeS, Transport Analysis Service Ltd (formerly BAC); Possibilities of Cost Reduction with All-Wing Aircraft, G. H. Lee, BSc, ARCS, DIC, FRAeS, Handley Page Ltd; and Prospects of Lower Airline and Airport Costs, A. H. Stratford, BSc(Eng), FRAeS, Consultant (formerly Hawker Siddeley International). Each paper was followed by a discussion and there was a general discussion at the end followed by a summing up by the Chairman. The Discussions have been summarised by J. A. Shaw, AFRAeS, Technical Department, Royal Aeronautical Society.

The importance of hydroelastic analysis of large and flexible container ships of today is pointed out. A methodology for investigation of this challenging phenomenon is drawn up and a mathematical model is worked out. It includes definition of ship geometry, mass distribution, structure stiffness, and combines ship hydrostatics, hydrodynamics, wave load, ship motion and vibrations. Based on the presented theory, a computer program is developed and applied for hydroelastic analysis of a flexible segmented barge for which model test results of motion and distortion in waves have been available. A correlation analysis of numerical simulation and measured response shows quite good agreement of the transfer functions for heave, pitch, roll, vertical and horizontal bending and torsion. The developed tool is furthermore used for hydroelastic analysis of a large container ship.

Control Study

Background: Suicide among children under the age of 15 years is a leading cause of death. Aims: The aim of the current study is to identify demographic, psychosocial, and psychiatric factors associated with child suicides. Method: Using external causes of deaths recorded in the Queensland Child Death Register, a case-control study design was applied. Cases were suicides of children (10–14 years) and adolescents (15–17 years); controls were other external causes of death in the same age band. Results: Between 2004 and 2012, 149 suicides were recorded: 34 of children aged 10–14 years and 115 of adolescents aged 15–17 years. The gender asymmetry was less evident in child suicides and suicides were significantly more prevalent in indigenous children. Children residing in remote areas were significantly more likely to die by suicide than other external causes compared with children in metropolitan areas. Types of precipitating events differed between children and adolescents, with children more likely to experience family problems. Disorders usually diagnosed during infancy, childhood, and adolescence (e.g., ADHD) were significantly more common among children compared with adolescents who died by suicide. Conclusion: Psychosocial and environmental aspects of children, in addition to mental health and behavioral difficulties, are important in the understanding of suicide in this age group and in the development of targeted suicide prevention.
