Standard allergy testing relies on identifying the immunoglobulin (Ig) E antibody specific for the allergen in question. Two classic methods of doing this are the immediate wheal-and-flare skin prick tests (in which a small amount of antigen is introduced into the skin and the site is evaluated after 15 minutes for the presence of an immediate wheal-and-flare reaction) and in vitro (blood) testing. Methods of allergy testing that do not have a clear scientific basis include cytotoxic testing, provocation-neutralization testing or treatment, and “yeast allergy” testing.

In a global effort, the key players have combined their R&D forces to work jointly on the next generation thermonuclear fusion device. The development of structural, heat-sink and armor materials for plasma interactive components is focusing on neutron irradiation damage, and its impact on property retention and component integrity. Consequently, the processing of materials, realistic component testing methods as well as modeling are being optimized to suit the newest design concept(s). Nondestructive inspection of components is now available at an accuracy needed to ensure long service in a harsh, nuclear environment. The most promising materials and best established manufacturing processes are described; the proposed qualification techniques for fusion in-vessel and heat removal systems are reviewed.

Abstract Metal-ceramic and all-ceramic prosthetic restorations in the patient mouth are often damaged by esthetic and functional problems that reduce their success and longevity. Аim: To evaluate methods for testing mechanical characteristics of dental ceramics through analysis of different testing methods. Material and methods: Dental ceramic materials are tested with in vivo and in vitro methods for their most important mechanical characteristics: hardness, toughness, flexural strength and abrasion. In vitro testing methods are faster and more efficient, without subjective factors from the patient according to ISO standards. Testing is done with universal testing machines, like Zwick 1445, Universal Testing Machine (Zwick DmbH & Co.KG, Ulm, Germany), Instron 4302 (Instron Corporation, England), MTS Sintech ReNew 1123 or in oral chewing simulators. Results: According to the testing results, flexure strength is one of the most important characteristic of the dental ceramic to be tested, by the uniaxial and biaxial tests. Uniaxial tests three-point and four-point flexure are not most appropriate because the main stress on the lower side of the tested specimens is tension that causes beginning fractures at the places with superficial flow. Uniaxial results for flexural strength are lower than actual force, while with biaxial test defects and flows on the edges of tested specimens are not directly loaded. Conclusion: Biaxial flexural method has advantages over uniaxial because of real strength results, but also for simple shape and preparing of the testing specimens.
