Damage Accumulation Phenomena in Multilayer (TiAlCrSiY)N/(TiAlCr)N, Monolayer (TiAlCrSiY)N Coatings and Silicon upon Deformation by Cyclic Nanoindentation.

The micromechanism of the low-cycle fatigue of mono- and multilayer PVD coatings on cutting tools was investigated. Multilayer nanolaminate (TiAlCrSiY)N/(TiAlCr)N and monolayer (TiAlCrSiY)N PVD coatings were deposited on the cemented carbide ball nose end mills. Low-cycle fatigue resistance was studied using the cyclic nanoindentation technique.

Enhancement of Multi-Scale Self-Organization Processes during Inconel DA 718 Machining through the Optimization of TiAlCrSiN/TiAlCrN Bi-Nano-Multilayer Coating Characteristics.

Optimization of the composition of a new generation of bi-nano-multilayered TiAlCrSiN/TiAlCrN-based coatings is outlined in this study for the machining of direct aged (DA) Inconel 718 alloy. Three types of TiAlCrSiN/TiAlCrN-based bi-nano-multi-layer coatings with varying chemical compositions were investigated: (1) a previous state-of-the-art TiAlCrSiYN/TiAlCrN (coating A); (2) TiAlCrSiN/TiAlCrN with increased amount of Si (up to 8 at.%; coating B); (3) a new TiAlCrSiYN/TiAlCrN coating (coating C) with an increased amount of both Si and Y (up to 5 at.

[Effectiveness of laparoscopic cholecystectomy for acute cholecystitis].

Objective: To analyze the impact of laparoscopic cholecystectomy on in-hospital and postoperative mortality in patients with acute cholecystitis.

[The psychological characteristics of interaction between patient and physician of traumatology department].

The actual conditions of "physician-patient" interaction in hospital department presents high requirements to quality and rate of provided services. The development of conflicts because of misunderstanding of behavior motivation of physician and patient in hospital department determined purpose of actual study. The standardized psychological questionnaire "Big Five" and Myers-Briggs questionnaire were used to obtain needed data.

[Fusion proteins encoded by orf 129L of ectromelia and orf A30L of smallpox viruses cross-react with neutralizing monoclonal antibodies].

Open reading frame (orf) 129L of ectromelia (EV) and orf A30L of smallpox viruses (SPV) encoding fusion proteins were cloned and expressed in E. coli cells. The recombinant polypeptides (prA30L H pr129L) were purified from cell lysates by Ni-NTA chromatography.
