Overview. My work is in the area of commutative algebra, and is motivated by the connections between algebra and geometry. Commutative algebra is the study of commutative rings (e.g. polynomial rings over fields and their quotients) and modules over these rings, while algebraic geometry is the study of finitely many polynomial equations in finitely many unknowns. The set of all solutions to suc...

The Daniel Fast is a biblically inspired dietary program rich in carbohydrate, most closely resembling a vegan diet but with additional restrictions, including the elimination of processed foods, white flour products, preservatives, additives, sweeteners, caffeine, and alcohol. While no specific requirements are placed on the ingestion of specific percentages of macronutrients, the mean daily c...

Here, we report the complete genome sequence of Xanthomonas arboricola pv. juglandis 417, a copper-resistant strain isolated from a blighted walnut fruit (Juglans regia L. cv. Chandler). The genome consists of a single chromosome (5,218 kb).

Abnormal prion protein (PrP(Sc)) plays a central role in the transmission of prion diseases, but the molecular basis of prion strains with distinct biological characteristics remains to be elucidated. We analyzed the characteristics of prion disease by using mice inoculated with the Chandler and Fukuoka-1 strains propagated in a cultured mouse neuronal cell line, GT1-7, which is highly permissi...

Like all human institutions, firms are constructed entities--that is, they are the products of social and cultural (as well as economic) processes, and indeed, vary quite strikingly from one nation to the next.• In some ways, of course, this is an obvious point, but it is a point that business historians too often ignore. For example, scholars who write about industry during the nineteenth cent...

Three different models, a modified Chandler loop, roller pump, and a new ball valve model (Hemobile), were compared with regard to intrinsic damage of blood components and activation of platelets. The Hemobile was used for testing of polymer tubes. High flow was not possible with the Chandler loop. The roller pump and the Hemobile could be adjusted to high flow, but he pump induced hemolysis. P...

Public demand for safer, environmentally-benign alternatives to synthetic chemical pesticides and more stringent barriers put in place by regulatory agencies worldwide has led to increased interest in microbial pest control agents (MPCA) based on viruses, bacteria, fungi, protozoa and nematodes as the active ingredient. The MPCA market has recently experienced an increase of 47% between 2004/20...

Alfred Chandler attributed the rise of the vertically integrated corporation in the twentieth century to improvements in transportation and communication. In contrast, many have argued that further advances in transportation and communication have made vertical integration obsolete in recent years, replacing it with modularity, outsourcing, and networking. This article unpacks this apparent puz...
