Granted: 2007-05-22
Abstract: The invention relates to a method of applying guidelines or guideribs in the walking direction for visually handicapped persons. The method is adapted for application in situ on an existing hard subsoil. It is, however, also adapted for the application of these guidelines or guideribs on tiles, etc., before the tiles are mounted. The method relates to the application of one or more groups of tight interrupted ribs parallel to each other, which as a group form a desired path width. Use is made of epoxy resins with additives, amongst which quartz powder in order to increase the strength against wear. The ribs formed have a rectangular vertical cross-section which is easily perceptible for visually handicapped persons with their cane or foot. As a result of the sharp corners the attention value is high, notwithstanding the fact that the rib is low. This gives a minimum of inconvenience for other users of the path and the ribs can easily be maintained.

Patent CA-2283767-C (CA)
Inventor: BLACKMER TRACY M
IPC: G06F19/00
Filed: 1999-09-27
Granted: 2007-06-19
Abstract: The invention provides a method for analyzing spatial variations in field and crop performance. The method allows analysis of the field and crop performance as a function of various treatment and/or environmental conditions. This method is an advance over the prior art in that it allows better defined, more accurate comparisons of adjacent test areas, eliminating the need for extrapolation of data and avoiding inaccuracies therefrom. Also, the more accurate comparisons allow better characterization of effects due to the environment, such as those caused by genotype by environment (G x E) interaction. The more accurately defined comparison units also lead to improved analysis when comparing to other data layers for non- spatial analysis. The invention also provides a system for carrying out this method. The system preferably includes a device for inputting spatially-referenced data, a memory, an output device, and a processor. The output data may be represented spatially or non-spatially. The information provided by the method and system of the invention will allow farmers to make more informed decisions regarding seed and farming inputs and practices, thereby maximizing agricultural productivity.

Granted: 2007-07-03
Abstract: Fusarium graminearum is a plant pathogen, attacking a wide range of plant species including corn (ear and stalk rot), barley, and wheat (head blight). Fusarium epidemics result in millions of dollars of losses in crop revenues. Fusarium graminearum infection in the cereals reduces both grain yield and quality. Mycotoxins are produced by many fungal Fusarium species and thus the grain becomes contamined with these mycotoxins, such as the trichothecenes. The major trichothecene produced by F. graminearum as well as F. culmorum is deoxynivalenol (abbreviated as DON, also known as vomitoxin). Trichothecenes are potent protein synthesis inhibitors and are quite toxic to humans and livestock. A yeast gene has been identified which is resistant to the trichothecene, trichodermin. A  corresponding plant gene has been prepared, which has been used to transform plants and would be suitable to transform animals. These transformed plants have an increased tolerance to trichothecenes and could be more resistant to Fusarium infestation. Potentially, transformed animals could have an increased tolerance to the trichothecene mycotoxins. This modified gene could also be used as a selectable marker in transformation experiments.
