As the series title implies each Clinician’s Desk Reference is a practical resource and a daily aid for physicians in the hospital setting and in primary care.Asthma is one of the most important chronic disorders in the developed world. Evidence from around the world shows the prevalence of asthma has increased considerably since 1975, and now affects around 7.2% of the world population (about 100 million individuals). In the UK asthma is now the most common chronic disease affecting all age groups with approximately 11% of the population being diagnosed as having asthma at some time in their lives.Understanding of the basic mechanisms involved in the pathogenesis of asthma has improved dramatically over the past 20 years. Along with this increase in basic scientific knowledge, randomized clinical trials have produced evidence to guide clinicians in how to manage patients with asthma.The book covers epidemiology, diagnosis and management, and takes a look at future developments. The authors highlight the under diagnosis of occupational asthma and emphasize the importance of effective patient education, particularly asthma action plans. There are ten clinical cases dealing with common diagnostic and management problems, frequently asked questions and appendices containing resources for patients and clinicians including useful websites, information leaflets and major references.

Jim Douglas, Jr.'' These proceedings reflect some of the thoughts expressed at the Oberwolfach Con­ ference on Porous Media held June 21-27, 1992, organized by Jim Douglas, Jr., Ulrich Hornung, and Cornelius J, van Duijn. Forty-five scientists attended the conference, and about thirty papers were presented. Fourteen manuscripts were submitted for the proceedings and are incorporated in this volume; they cover a number of aspects of flow and transport in porous media. Indeed, there are 223 individual references in the fourteen papers, but fewer than fifteen are cited in more than one paper. The papers appear in alphabetical order (on the basis of the first author). A brief introduction to each paper is given below. Allen and Curran consider a variety of questions related to the simulation of ground­ water contamination. Accurate water velocities are essential for acceptable results, and the authors apply mixed finite elements to the pressure equation to obtain these ve­ locities. Since fine grids are required to resolve heterogenei ties, standard iterative procedures are too slow for practical simulation; the authors introduce a parallelizable, multigrid-based it.erative scheme for the lowest order Raviart-Thomas mixed method. Contaminant transport is approximated through a finite element collocation procedure, and an alternating-direction, modified method of characteristics technique is employed to time-step the simulation. Computational experiments carried out on an nCube 2 computer.
