The paper studies ways in which the sets of a partition of a lattice in Rn become regular model sets. The main theorem gives equivalent conditions which assure that a matrix substitution system on a lattice in Rn gives rise to regular model sets (based on p-adic-like internal spaces), and hence to pure point diffractive sets. The methods developed here are used to show that the n−dimensional ch...

Grass weeds pose a serious management challenge in grain sorghum. Recent development of three herbicide-tolerant sorghum technologies such as Inzen, Igrowth, and DoubleTeam will provide the opportunity for producers to use nicosulfuron (Zest), imazamox (Imiflex), quizalofop-p-ethyl (FirstAct) grass weed control, respectively. The main objectives this research were (1) determine effectiveness Im...

Acidified vegetable products with a ph above 3.3 must be heat processed to assure the destruction of Escherichia coli O157:h7, Salmonella enterica, Listeria monocytogenes, and other pathogenic bacteria that might be present in the product. Recently, the Food and Drug Administration has required that linear models for heat process data be used with electronic process filing forms. Existing recom...
