It is an enormous honour for me to take over from Peter Bearman as Editor-in-Chief of the world's oldest aeronautics journal. Most of you will not know me and thus I'd like to give you a bit of background: I grew up in Bavaria and studied Aerospace Engineering at Stuttgart University. Under the German system it was common to work on the final research project (Diploma thesis) outside the University and I was lucky enough to find a suitable place in Cranfield. There, my supervisor was John Stollery, who led this journal as Editor-in-Chief for many years. After a PhD in hypersonic aerodynamics (also at Cranfield) I became a post-doctoral researcher at Tohoku University in Japan. 18 months later I returned to the UK to take up a lectureship in aerodynamics at the Engineering Department of Cambridge University where I am now the Professor of Aerodynamics, Head of the Fluids Group and Deputy Head of Department with responsibility for graduate education.

Storage Structures

New methods of moving manure to storages, new manure storage structures and new manure spreading technologies are now found on dairy farms. Consequently, farmers are in need of labor requirements, investment and annual cost data. The purpose of this article is to present current investment, labor and annual cost information that will aid farmers in making economical decisions relative to selecting alternative manure handling systems. Manure handling systems presented in Table 1 were planned for freestall housing and 75, 150 and 300 cow herd sizes. These systems were based on a survey of 98 dairy farms in the Monocacy River Watershed (Holik and Lessley), data from the Agricultural Engineering Department of the University of Maryland, the Soil Conservation Service and the Midwest Plan Service. The manure handling systems and herd sizes modeled are considered to be representative of dairies found in Maryland.

George Ritzer, a sociologist at the University of Maryland, has proposed an influential thesis that suggests that many aspects of the fast food industry are making their way into other areas of society. This article explores whether his thesis, known as the McDonaldization thesis, is applicable to academic libraries. Specifically, it seeks to determine to what extent academic libraries may be considered McDonaldized, and if so, what effect McDonaldization may be having on them. It also investigates some possible alternatives to McDonaldization, and their implications for academic libraries.

The paucity of reliable measures of team coordination and performance significantly obstructs the assessment of the effects of any technology on teams to improve decision making in health care. A pilot study was conducted to determine if measures of coordination and performance could be developed for teams involved in trauma resuscitation. A video assisted review of cases enabled evaluation of the use of the tools. Descriptors of coordination were derived from Klein's five-stage model of team coordination. A scoring system of team performance was developed from the University of Maryland Team Observable Performance Metric (UMTOP). After some modification both coordination and performance could be described. However, four defined stages of resuscitation were observed which greatly improved coding. More rigorous assessments of these tools will be required before firm conclusions can be drawn about the effects of a decision support tool recently introduced into the environment.

Abstract Double adjustable shock absorbers allow for independent adjustment of the yield force and post-yield damping in the force versus velocity response. To emulate the performance of a conventional double adjustable shock absorber, an electrorheological (ER) and magnetorheological (MR) automotive shock absorber were designed and fabricated at the University of Maryland. For the ER shock absorber, an applied electric field between two tubular electrodes, located in the piston head, increases the force required for a given piston rod velocity. For the MR shock absorber, an applied magnetic field between the core and flux return increases the force required for a given piston rod velocity. For each shock absorber, two different shaped gaps meet the controllable performance requirements of a double adjustable shock absorber. A uniform gap allows for control of the yield force of the shock absorber, while a non-uniform gap allows for control of the post-yield damping. Force measurements from sinusoidal displacement cycles, recorded on a mechanical damper dynamometer, validate the performance of uniform and non-uniform gaps for adjustment of the yield force and post-yield damping, respectively.
