"Knowledge Engineering Paradigms in Bio-Medical Knowledge-Based Systems"
Knowledge engineering paradigms (KEPs) deal with the development of intelligent systems in which reasoning and knowledge play pivotal role. Regarding the reasoning mechanism, there are many approaches of reasoning e.g.; automated, spatial, temporal, commonsense, fuzzy, geometric, non-monotonic reasoning, model-based reasoning, probabilistic, causal reasoning, qualitative reasoning, and case-based reasoning . Regarding the knowledge base, there are many techniques for representing both static and heuristic knowledge, e.g.; semantic networks, scripts, If-then rules, ontology, and cases.
On the other side , bio-medical knowledge-based systems are an intellegent systems and based on the concepts and theories of many sciences ,e.g. artificial intelligence, data science ,social science,information science, computer science, behavioral science ,life sciences and health care. In this paper we focus our discussion around some of KEPs which are used in developing the intelligent knowledge-based systems in biology and medicen domains.. In addition, the paper presents some examples of the developed systems by the author and his colleagues at Artificial intelligence and Knowledge Engineering Research Labs,Ain Shams University,Cairo,Egypt.

"Modern Approach of Base Metal Dental Alloys Processed by Alternative Manufacturing Technologies"
Alternative manufacturing methods of base metal dental alloys are of ongoing interest, having a growing impact in the field of dental technology. The potential for fabricating metallic dental components with a complex geometry directly from digital data using automated equipment and appropriate materials is very significant. Digital technologies can be classified as based on subtractive manufacturing, such as the milling of premanufactured materials assisted by computer-aided design/computer-aided manufacturing (CAD/CAM) systems or on additive manufacturing (AM), such as the recently developed laser-based 3D printing methods. AM may not become the dominant manufacturing technology in dental field, but represents an excellent opportunity to increase their influence in achieving dental restorations. Understanding of structural and microstructural defects present in metals processed through 3D printing/AM techniques and post-processing protocols such as heat treatment to reduce these defects, are important in order to transform the microstructures to those acceptable for practice. Taking into account the many benefits of AM technologies, and the findings regarding the studied structural and morphological characteristics of Co-Cr dental alloys processed by alternative manufacturing techniques, more research is required in order to understand the influence of microstructure on restoration properties, further veneering procedures of the frameworks, and last but not least the clinical behavior.
