Nitrogen fixation is a key component of the nitrogen cycle, one of the most fundamental cycles in the biosphere. Conversion of atmospheric nitrogen into organic nitrogen compounds can be carried out only by certain bacteria and blue-green algae (cyanobacteria). Some nitrogen fixing bacteria live symbiotically with leguminous plants such as peas, beans, clover, and certain tropical trees in nodules on the plants' roots, while others live independently in the soil and aquatic habitats. By the activity of these microorganisms, the soil is enriched with the nitrogen required for plant growth and function. Thus the topic is of considerable practical as well as fundamental importance. In Biological Nitrogen Fixation, the leading researchers in nitrogen fixation from all over the world contribute up-to-the-minute general reviews on all aspects of the subject, from the molecular biology and genetics to the biochemistry, physiology, and ecology of nitrogen fixation. This compendium of current research is an indispensable reference for all involved in nitrogen fixation research, and of use to all who deal indirectly with the subject. It will also serve as a thoroughly up-to-date textbook for graduate students in microbiology, plant science, biochemistry, molecular biology, plant pathology, agronomy, and genetics.

When the author was born, his mother did the unthinkable. She gave him a girl's name-Stacey.

But Stacey's name was just the first hurdle he'd face in his uphill climb from birth to manhood. He also had to deal with an entitled older brother, the hodgepodge of different men his mother was involved with, and the nomadic lifestyle he was forced to endure for five years. And to top it all off, his mother couldn't cook a decent meal to save her life.

"Trailer Trash, With a Girl's Name" is Stacey Roberts' lighthearted, often hilarious account of growing up in an unstable household during the 1980s. Full of humor, history, and hope, it follows Stacey from the hospital room where he was born to the Winnebago that carried him across the country, filling in the gaps with a wit and humor that anyone with a dysfunctional family can appreciate.

So go ahead and start reading. Once you hop aboard the Winnebago with Stacey and his quirky family, you'll find that you're in for the ride or your life, where what you learn along the way is not only entertaining, but also enormously enriching.
