Food preservation uses many processes to improve quality and/or to extend shelf life of fruits and vegetables. One of these processes is osmotic dehydration that is a pretreatment before conventional drying. This process usually produces food with intermediary level of moisture. Osmotic dehydration can be optimized using mathematical modelling but it can(More)
A relatively inexpensive image analysis system has been developed to semi-automate the detection and quantification of microbial growth in sections of food. A system based on an IBM PC compatible, with a frame store card, was programmed to scan Gram-stained sections using a motorized stage. Each field of view was thresholded after subtraction of a(More)
The authors presents a clinical case treated with brachytherapy performed with special mold of gold-198 disc, with the purpose of evaluating the distribution of radiation dose, the viability of manufacturing the radioactivity prosthesis and its operational cost. In despite of being only one case, we can conclude that the prosthesis with gold-198 foils can(More)
