Among the issues we are addressing are carbon impact, paper specifications and procurement, ethical conduct within our business and among our vendors, and community and charitable support. In 2008, we launched a Corporate Citizenship Initiative, a global effort to address the environmental, social, economic, and ethical challenges we face in our business. Our company is built on a foundation of principles that include responsibility to the communities we serve and where we live and work. has been a valued source of knowledge and understanding for more than 200 years, helping people around the world meet their needs and fulfill their aspirations.

The organization of the material is similar to Bird/Stewart/Lightfoot, but presentation has been thoughtfully revised specifically for undergraduate students encountering these concepts for the first time. The text covers topics such as: the transport of momentum the transport of energy and the transport of chemical species. Some of the rigorous topics suitable for the advanced students have been retained. The authors’ goal in writing this book reflects topics covered in an undergraduate course.

Lightfoot, and Daniel Klingenberg is a new introductory textbook based on the classic Bird, Stewart, Lightfoot text, Transport Phenomena.
