Abstract:

Firefighters face a major threat when intervening in a building during a fire: the possibility of structural collapse during the cooling phase of the fire, or soon thereafter. At present, this threat is amplified by the fact that the behaviour of structures after the time of peak gas temperature is not well understood, and is not taken into account in the design. This work presents an analysis of the behaviour of different structural members under natural fires, and develops a method for characterizing their sensitivity to fire decay phases. Thermo-mechanical numerical simulations based on the

Abstract:

The process of operation of vehicles is determined by the interaction of the wheel and rail. The result is the effect arising from the friction of rolling and especially from the friction of the wheel sliding on the rail during braking, in relation to these changes there is a significant increase in the intensity of wear of the wheels of rolling stock. Based on research in recent years, it is known that the strength of pearlitic rail steels has reached its limit. Based on the literature analysis, steels used in world practice for the production of railway rails from bainite were identified and

Abstract:

A departure from a linear or an exponential intensity decay in the diffracting power of protein crystals as a function of absorbed dose is reported. The observation of a lag phase raises the possibility of collecting significantly more data from crystals held at room temperature before an intolerable intensity decay is reached. A simple model accounting for the form of the intensity decay is reintroduced and is applied for the first time to high frame-rate room-temperature data collection.

The morphology and micro-structural change, after different cycles, were studied by a scanning electron microscope (SEM) and transmission electron microscopy (TEM) to understand the mechanism of the capacity decay.

Mudstone is a natural type of geological material, which has different ways of mechanical response between natural state and dry-wet cycles. According to the complex damage theory of geological materials, rock masses can be considered as a composite material consisting of the structure phase and damage phase. The essence of the damage of rock masses is a damage evolution process, during which the deformation energy of the structure phase converts into dissipation energy of the damage phase, and the energy dissipation from phase transformation promotes the structure phase to change into the dam

Abstract:

Multicomponent fluorides of rare earth elements (REEs—R) are phase transition-type negative thermal expansion (NTE-II) materials. NTE-II occurs in RF3-R′F3 systems formed by “mother” single-component dimorphic RF3 (R = Pm, Sm, Eu, and Gd) with a giant NTE-II. There are two structural types of RF3 polymorphic modifications: low-temperature β-YF3 (β−) and high-temperature LaF3 (t−). The change in a structural type is accompanied by a density anomaly: a volume of one formula unit (Vform) Vβ− >Vt−. The empirical signs of volumetric changes ΔV/V of NTE-II materials were considered.

Abstract:

A comprehensive understanding of the time-dependent flow behavior of concentrated oil-in-water emulsions is of considerable industrial importance. Along with conventional rheology measurements, localized flow and structural information are key to gaining insight into the underlying mechanisms causing time variations upon constant shear. In this work, we study the time-dependent flow behavior of concentrated egg-yolk emulsions with (MEY) or without (EY) enzymatic modification and unravel the effects caused by viscous friction during shear. We observe that prolonged shear leads to irreversible a

Abstract:

YAG:Ce ceramics by the direct action of an electron beam with 1.4 MeV energy were synthesized on a mixture of a stoichiometric composition of Y, Al, and Ce oxides without adding any substances to facilitate the process. The synthesis is realized in a time less than 1 s. The main structural phase of the obtained ceramics is YAG and YAP can be additional. The luminescence characteristics of the synthesized samples, the excitation, luminescence, decay time, and pulsed cathodoluminescence spectra, are similar to those known for YAG:Ce phosphors.

Abstract:

This essay argues that Anthony Trollope introduces a framework of character growth and decay, evinced through organic metaphors of ripening and rotting, to distinguish good and bad characters in The Small House at Allington and The Last Chronicle of Barset. By comparing a developing protagonist with a mature one who enters a phase of decline, we see how Trollope's commitment to nuanced characterisation is disrupted by his didactic aim of designating, and then torturing, patently bad figures. An analysis of the psychologies and aesthetics of character, framed around Julia Kristeva's theory of a

The phosphors' crystal phase and microstructure, as well as their luminescence, were studied. The particle size is around 1m, which is significantly smaller than what the solid-status process produces. When particles are combined of silicon and deposited on a blue light-emitting diode (LED), finer particles can minimize interior diffusing. A significant green

The aim of the work is to review the analytical models of austenite decay, taking into account the internal stresses obtained by various authors. It is shown that a common drawback of the known works is the neglect of the effect of the stress-strain state arising during the heat treatment of parts on the kinetics of structural transformations, while the available experimental data indicate a significant effect of stresses and strains on structural transformations. It has been established that the experimental data accumulated to date do not allow reliably describing the effect of the stress st

We propose a 2D representation in the frequency-decay factor plane of an arbitrary real-world vibration signal. The signal is expressed as the sum of a decayed-attenuation sine term modulated by an amplitude function and a noise residue. We extend the combined approach of Capon estimation and amplitude and phase estimation (CAPES) to damped real vibration signals (DR-CAPES). In the proposed DR-CAPES method, the high-resolution amplitude and phase are estimated simultaneously for both angular frequency and decay factor grids. The performance of the proposed approach is tested numerically with n

Phases devoid of curium (hollandite and freudenbergite) experience a flux of ionizing radiation, and may also undergo radiation-induced structural degradation.

Additionally, the influence of the coexistence of Li/Na in the alkali metal layer on ion migration and phase transformation in LNMO has been revealed. In the
