Quality Estimation of Canola Using Machine Vision and Vis-nir Spectroscopy

Canola is mainly graded either by visual inspection or by smelling. These methods are subjective in nature and are bound to cause errors while deciding the grade of canola. To test canola for amount of erucic acid present the sample needs to be sent to a laboratory for testing through wet chemical analysis. This is a time consuming process. An electronic method that can quantify amount of dockage, presence of distinctly green and heat treated seeds, distinguish samples on the basis of erucic acid, its free fatty acid content and PV, would not only be less time consuming but also would be a more reliable method to grade canola samples. Findings and Conclusions: 1. Canola samples cannot be classified on the basis of total dockage present using L and RGB data obtained from flat-bed scanner. Inclusion of morphological and textural features would improve the classification accuracy. 2. Machine vision can be considered as a potential method to grade canola on the basis of good, distinctly green and heat damagedBiosystems and Agricultural Engineerin

Co-existence of breast and ovarian cancers in BRCA germ-line mutation carriers

The co-existence of breast and ovarian cancers in the same individual should raise suspicion of a hereditary process. Patients with either BRCA1 or BRCA2 germ-line mutations have an average risk of 39% and 11% respectively of developing ovarian cancer by the age of 70; they have a risk of 35–85% of developing breast cancer in their lifetime. We report here unusual pathologic features in a BRCA2 germ-line mutation carrier recently diagnosed with synchronous breast and ovarian cancers, and summarize the findings in six other women who were diagnosed with ovarian cancer either simultaneously with the diagnosis of breast cancer or at varying times after the diagnosis. While in most instances this may be a coincidental occurrence in highly susceptible individuals, the patient we highlight raises the provocative hypothesis that at times breast cancer metastasizes to the ovaries of mutation carriers and stimulates the development of an ovarian cancer as well as other cancers. In addition, these ovarian cancers may have different mechanisms of metastases predisposing them to travel to unusual sites
