INTRODUCTION One of the most striking developments in twentieth-century medicine has been the growing involvement of laboratory science in day-to-day medical practice. Not only are scientific laboratories employed extensively in the diagnosis and investigation of illness, but it is now commonplace to regard doctors as, in many ways, applied scientists. This is a far cry from the situation at th...
BACKGROUND Molecular diagnostic methods have played and continuing to have a critical role in clinical laboratories in recent years. Therefore, standardization is an evolutionary process that needs to be upgrade with increasing scientific knowledge, improvement of the instruments and techniques. The aim of this study was to design a quality assurance program in order to have similar conditions ...
Background and Objectives: Particular importance of hazardous wastes is due to having characteristics such as toxicity, flammability, corrosively and reactivity. Some of the chemical wastes due to having hazardous materials must be collected and managed in a proper manner, since they are potentially harmful to the environment. Owing to the fact that educational centers have important roles in d...
University chemical laboratory is a high-risk place for teaching and scientific research due to the presence of various physical hazards. In recent years, university accidents occur frequently. This urges need enhance lab safety. A semi-quantitative methodology comprising Matter-Element Extension Theory (MEET) implemented with Combination Ordered Weighted Averaging (C-OWA) operator proposed ass...
Metallographic investigations are critical in research and materials’ quality control. Therefore, these methods very present scientific industrial activities. In particular for control, metallographic analyses have an indirect correlation with quality, time economic aspect the metallurgical industry. Most of used aluminium alloys’ determination non-standard required by customers. The suitabilit...
The recent revision of ISO15189 has further strengthened its position as the standard for accreditation for medical laboratories. Both for laboratories and their customers it is important that the scope of such accreditation is clear. Therefore the European co-operation for accreditation (EA) demands that the national bodies responsible for accreditation describe the scope of every laboratory a...
Background: Acrylamide (C3H5NO) is a vinyl monomer. This water-soluble crystalline solid is a colorless, odorless agent which is used in scientific laboratories and some industries. Acrylamide has cellular oxidative effects. Acute or chronic poisoning with this agent happens as a result of skin, respiratory, or oral contacts. Clinical manifestations depend on the dose, duration, and frequency...
A wide variety of mathematical and statistical software tools are available today, and the list grows daily. Means for representing and storing data and scientific information are likewise increasing, from sophisticated database and knowledge base technologies to high-speed, high-resolution graphics. Imagine a computing environment that couples all of these in a user-friendly way, using the bes...
