The paper presents the results of laboratory measurement of temperature in the machining zone during the straight turning of a shaft made of the AMS 5643 steel. The machining trials were recorded using the FLIR 620 thermographic camera, and the ThermaCam Researcher software was used to archive and analyse the measurement results. The experimental test plan for varying machining parameters (vc, ap, f) was developed using the Taguchi method, and the ANOVA was used for statistical processing of results. The experiment involved nine trials with a coated insert and nine trials with an uncoated insert. The obtained results will be used to improve the cutting process simulation model.

Grafts of cultured allogenic or autogenic keratlnocytes have proven to be an effective treatment of chronic wounds and burns. This study utilized a collagen substrate for keratinocyte and fibroblast attachment. The substrate provided mechanical stability and augmented graft manipulation onto the wound bed. Graft integrity was confirmed by light and transmission electron microscopy.Bovine Type I dermal collagen sheets (100 μm thick) were crosslinked with 254 nm UV light (13.5 Joules/cm2) to improve mechanical properties and reduce degradation. A single cell suspension of third passage neonatal foreskin fibroblasts were plated onto the collagen. Five days later, a single cell suspension of first passage neonatal foreskin keratinocytes were plated on the opposite side of the collagen. The grafts were cultured for one month.The grafts were fixed in phosphate buffered 4% formaldehyde/1% glutaraldehyde for 24 hours. Graft pieces were then washed in 0.13 M phosphate buffer, post-fixed in 1% osmium tetroxide, dehydrated, and embedded in Polybed 812.
