Express Method to Estimate Structural Imperfection and Bone Tissue Status
Journal Title: Strojnicky casopis - Journal of Mechanical Engineering - Year 2018, Vol 68, Issue 3
Abstract
A new method for evaluating the bone status using the scattering parameter of hardness indexes (Weibull homogeneity coefficient m) is proposed. A comparative analysis of the condition of the bone tissue of birds, depending on age, breed and calcium content, is conducted. It is established that the scattering degree of mechanical properties, in particular, hardness, is a very structure-sensitive parameter.

Thermo-Hydraulic Behaviour of Coolant in Nuclear Reactor VVER-440 Under Refuelling Conditions
The paper presents the numerical simulation of thermo-hydraulic behaviour of coolant in the VVER- 440 nuclear reactor under standard outage conditions. Heating-up and flow of coolant between the reactor pressure vessel...
Press-Fit Evaluation and Study of Displacement in Temperature Changes
The article is devoted to bearing analysis, which has a specific shape. The outer ring is the body directly and the inner ring is the case. To determine optimal radial clearance or overlap are used the thermal / struct...
Thermal Characteristics of High Temperature Naturally Circulating Helium Cooling Loop
The paper deals with the process properties in terms of the heat transfer, i.e. the thermal performance of the thermal-process units within a helium loop intended for the testing of the decay heat removal (DHR) from th...
