1. Introduction
1) Definition of preservation and food-spoilage micro-organisms
Food preservation is the process of treating and handling food to stop or greatly slow down spoilage (loss of quality, edibility or nutritive value) caused or accelerated by micro-organisms. Some methods, however, use benign bacteria, yeasts or fungi to add specific qualities and to preserve food (e.g., cheese, wine

any systems become degraded by electromagnetic interference (EMI) – by external or internal sources, such an occurrence can result in a disaster. To prevent degradation at any electromagnetic environment, all weapon systems and individual equipments must meet a series of electromagnetic compatibility (EMC) standards. Testing to ensure that these EMC standards are met is not an easy task.
