Radical Theory of Rings distills the most noteworthy present-day theoretical topics, gives a unified account of the classical structure theorems for rings, and deepens understanding of key aspects of ring theory via ring and radical constructions. Assimilating radical theory's evolution in the decades since the last major work on rings and radicals was published, the authors deal with some distinctive features of the radical theory of nonassociative rings, associative rings with involution, and near-rings. Written in clear algebraic terms by globally acknowledged authorities, the presentation includes more than 500 landmark and up-to-date references providing direction for further research.

Microsensors and MEMS (micro-electro-mechanical systems) are revolutionising the semiconductor industry. A microsystem or the so-called "system-on-a-chip" combines microelectronic circuitry with microsensors and microactuators. This emergent field has seen the development of applications ranging from the electronic nose and intelligent ear to micro-tweezers and the modern ink-jet nozzle.

Providing a complete overview of microsensor technologies, this unique reference addresses vital integration issues for the successful application of microsensors, MEMS and smart devices.

Features include:

• Review of traditional and emerging fabrication processes including bulk and silicon micromachining, microstereolithography and polymer processing methods.
• Focus on the use of IDT (interdigital transducer) microsensors in the development of low energy budget, wireless MEMS or micromachines.
• Coverage of the katest applications in smart devices including the electronic nose, tongue and finger, along with smart sensors and strcutures such as smart skin.
• An overview of the development of intelligent sensing devices through the use of sensor arrays, parametric compensation of sensor sugnals and ASIC technology.
• Comprehensive appendices outlining vital MEMS material properties, relevant web sites and a guide to key institutions active in the field.

"Liberty and duty, freedom and responsibility. That's the deal." John W. Gardner's life was dedicated to revitalizing the American Dream, a dream that must be recreated by each generation of caring citizens as they reshape it to meet the unrolling future. Now more than ever, citizens must step up and take action to create the world in which we want to live.

Living, Leading, and the American Dream is an inspiration— and a call to action. Beginning with an exploration of Gardner's life and values in his own words, this stirring and engaging collection shares Gardner's vision on personal renewal, community, leadership, and civic engagement.

The essays and speeches collected in this transformational volume are founded on Gardner's belief that we as a people want freedom— freedom at home as well as a world where freedom is possible. They are founded on his deep belief in the dignity and worth of the individual and his unshakable resolve to protect and preserve that dignity. They are founded on his belief that men and women should be empowered to achieve the best that is in them, and that we are the declared enemies of all conditions, such as disease, ignorance, or poverty, that stunt the individual and prevent such fulfillment.

And they are founded on the fact that achieving these goals is difficult and requires the commitment of all citizens. The essays in Living, Leading, and the American Dream move from individual to community to society, offering Gardner's vision on the role of the individual in attaining the greater good. Leaders of innovative organizations, civic leaders, and concerned citizens will find guidance and inspiration in Gardner's unique vision of every citizen's responsibility and capacity to make a difference.
