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.

highlights, the majority were not satisfied with the effectiveness of their preventive maintenance program. Why could this phenomenon happening?
The basic reason of owner’s hesitate the PM program; is not easy to visible performance. First, the economic value of preventive maintenance is difficult to determine. One of the most important think of the owner is the cost. However, it is difficult
