Erin Ontario In Photos

RRP $12.99

Erin, Ontario is the subject of Book 22 in the Cruising Ontario series of books of photographs of towns and cities in Ontario. The photos show the architecture and design of old buildings, many that are over 100 years old, with some descriptions of the buildings and background information, but mostly it is a visual experience to enjoy. A small community began at the headwaters of the Credit and Grand Rivers with the erection of mills in 1829-30. The mills were later rebuilt by Daniel McMillan who is in our extended family tree. As we drive from our home in Dundas to the home of our sons and their families in Orangeville, we pass through Erin, often stopping at the bakeshop, and now occasionally making a stop at the Tim Horton's.


The Photosynthetic Bacterial Reaction Center: Ii

The NATO Advanced Research Workshop entitled "The Photosynthetic Bacterial Reaction Center: Structure, Spectroscopy, and Dynamics" was held May 10-15, 1992, in the Maison d'H6tes of the Centre d'Etudes Nuc1eaires de Cadarache near Aix-en-Provence in the south of France. This workshop is the most recent of a string of meetings which started in Feldafing (Germany) in March 1985, soon after the three-dimensional structure of the bacterial reaction center had been elucidated by X-ray crystallography. This was followed, in September 1987, by a workshop in Cadarache and, in March 1990, by a second meeting in Feldafing. Although one of the most important processes on Earth, photosynthesis is still poorly understood. Stimulated by the breakthrough of solving the bacterial reaction center structure at atomic resolution, the field of relating this structure to the function of the reaction center, i. e. the remarkably efficient conversion and storage of solar energy, has been developing vigorously. Once the general organization of the cofactors and some details of the protein-cofactor interactions were known, it became possible to combine a variety of spectroscopic techniques with the powerful tool of site-directed mutagenesis in order to address increasingly incisive questions about the specific role of some amino acid residues in the electron transfer process. Still another promising tool is being developed, namely the exchange of a number of the native bacteriochlorophyll and bacteriopheophytin cofactors by chemically modified pigments.


Biological Control Of Photosynthesis

All measurements of intact leaf 02 sensitivity can be explained by the oxygenation model for glycolate formation and glycolate metabolism by established pathways. Predicting the rate of oxygenation from the underlying biochemistry is more reliable than calculating the rate of oxygenation from intact leaf gas exchange measurements. REFERENCES 1.
