By studying the geometrical features and the mechanical characters of the profiles during the roller leveling process and combining the basic elastic-plastic theories, a mechanical model is established which is suitable for analyzing elastic-plastic bending of the profile during roller leveling process. Using this model, the straightening effects have been analyzed under different roller leveling process schemes for the profiles which have typical initial curvatures. The analysis of roller leveling process confirms that the curvature ranges of the profiles can't converged infinitely under any

Abstract Nickel base superalloy René 65 is a cast-wrought derivative of René 88DT. Lower cost and comparable physical properties allow René 65 to serve as a promising candidate material for turbine disks in next-generation aeroengines. The cast-wrought route leads to significant segregation of solute elements during solidification of René 65, which should be reduced by a proper homogenization scheme. We use René 65 samples from a Ø 450 mm electros-slag remelting ingot (sample Disk I) and a Ø 250 mm pilot vacuum arc remelting ingot (sample Disk II) to investigate as-cast microstructure and homo

Investigations have been carried out in respect of structural steel and titanium alloy fatigue at various cyclic loading frequencies and these investigations have made it possible to reveal regularities in changes of parameters pertaining to fatigue resistance and stability behaviour of the tested materials. A change in cyclic loading frequency affects duration of a single (during one cycle) stay of the material in the loaded state and it has an impact on its durability. In addition, with an increase in frequency of load cycles, deformation rate becomes higher, and stress build-up time is decr

In addition, it was found that the plastic recovery was fast and stable when the temperature was lower than 725 °C (the lowest plastic temperature). Bending/straightening operation in this temperature range was conducive to controlling the generation of corner cracks. In orde

AbstractActors are required to engage in multimodal modulations of their body, face, and voice in order to create a holistic portrayal of a character during performance. We present here the first trimodal analysis, to our knowledge, of the process of character portrayal in professional actors. The actors portrayed a series of stock characters (e.g., king, bully) that were organized according to a predictive scheme based on the two orthogonal personality dimensions of assertiveness and cooperativeness. We used 3D motion capture technology to analyze the relative expansion/contraction of 6 body

AbstractAdaptative objects based on shape-memory materials are expected to significantly impact numerous technological sectors including optics and photonics. In this work, we demonstrate the manufacturing of shape-memory optical fibers from the thermal stretching of additively manufactured preforms. First, we show how standard commercially-available thermoplastics can be used to produce long continuously-structured microfilaments with shape-memory abilities. Shape recovery as well as programmability performances of such elongated objects are assessed. Next, we open the way for light-guiding m

We numerically investigated the aggregation dynamics and resulting network structures of colloidal gels using the slippery diffusion-limited cluster aggregation (DLCA) model. In this model, bonds are irreversibly formed upon the particle contacts, but the angles among them are not fixed, unlike the conventional DLCA. This allows clusters to be deformed in the process of aggregation. By characterizing the aggregation dynamics and using a reduced network scheme, our simulation revealed two distinct branching structure formation routes depending on the particle volume fraction ϕ. In lower volume

Aims: to study the effect of oral administration of biologically active supplement "VITABEAUTY® Hyaluronic Acid + Resveratrol" on structural and functional parameters of facial skin. Materials and methods: a simple blind placebo-controlled cross-over study was conducted in which 40 female patients aged 30 to 45 years with signs of dryness, decreased hydration and elasticity of facial skin, the first signs of aging and wrinkles took part. The observation was carried out for 10 weeks. The dietary supplement and placebo were taken according to the following scheme: during the first 4 weeks of the
