Squamous cell carcinoma (SCC) of the skin is one of the mostcommon non melanoma skin cancers (NMSC), along withbasal cell carcinoma (BCC). Besides ultraviolet radiation,exposure to industrial agents, ionizing radiation, and areas ofchronic inflammation are associated with the development ofSCC. Squamous cell carcinoma may also be associated withforeign bodies. We report a rare case of cutaneous...

Considerable research has been conducted over recent decades on the role of non‑metallic inclusions and their link to the machinability of different steels. The present work reviews the mechanisms of steel fractures during different mechanical machining operations and the behavior of various non-metallic inclusions in a cutting zone. More specifically, the effects of composition, size, number a...

In this thesis we outline how to represent rough and fuzzy sets in intuitionistic type theory. The inherent meaning of such constructs are valuable when it comes to representing certainty in complex data structures to be used and reasoned on within the context of computer science. We ask fundamental questions regarding how to represent and understand non-binary inclusion within the constructive...

In order to evaluate cleanliness of steel samples which contain oxygen in two different forms - chemically dissolved form and physically dispersed matrix, identification each the is important. A simple but promising method for simultaneous analysis these types was developed present study using Inert Gas Fusion Infrared Absorption Method. By utilizing carbothermic reaction temperature type oxyge...

If a liquid is undercooled below its equilibrium melting temperature an excess Gibbs free energy is created. This gives access to solidification of metastable solids under non-equilibrium conditions. In the present work, techniques of containerless processing are applied. Electromagnetic and electrostatic levitation enable to freely suspend a liquid drop of a few millimeters in diameter. Hetero...

Particles in molten steel, including argon-gas bubbles, slag droplets, and non-metallic inclusions, are removed into the surface-slag layer or captured by solidifying steel-shell during continuous steel casting. Captured particles often become serious defects final product, so understanding particle-capture mechanisms is important for quality. Slab casters have a straight mold upper-strand prio...
