Abstract:

AbstractDuring heating of Al alloys, typically a sequence of precipitation and dissolution reactions occurs and the single (partly opposing) reactions superimpose. Differential scanning calorimetry (DSC) is one common technique to analyse the kinetic development of precipitation and dissolution in Al alloys, but the superposition of the exothermic precipitation and endothermic dissolution reactions complicates the DSC signal interpretation, as DSC measures the sum of any heat effect. Synchrotron high-energy X-ray diffraction (HEXRD) allows the kinetic development of phase transformations to be

Abstract:

The phase transformations occurring during the heat treatments leading to transformation-induced plasticity (TRIP)-aided bainitic steel have been investigated in-situ by high-energy X-ray diffraction (HEXRD) conducted with synchrotron light at 90 keV. Direct microstructure characterization has been performed by electron microscopy using electron backscatter diffraction and orientation and phase mapping in a transmission electron microscope. HEXRD data allow the quantification of the evolution of the austenite phase fraction with the heat treatments, as well as its carbon content and the fracti

Abstract:

In-situ high energy X-Ray diffraction (HEXRD) was used on compositionally graded steels to study the effect of substitutional elements on ferrite growth kinetics in Fe–C–X and Fe–C–X–Y systems. Two systems were selected to illustrate the applicability of the combinatorial approach in studying such transformations, Fe–C–Mn and Fe–C–Mn–Mo. Comparison between the measured ferrite growth kinetics using HEXRD and the predicted ones using Para-Equilibrium (PE) and Local Equilibrium with Negligible Partitioning (LENP) models indicates that the fractions reached at the stasis of transformation are low

Structure-sensitive catalyzed reactions can be influenced by a number of parameters. So far, it has been established that the formation of Pd-C species is responsible for the behavior of Pd nanoparticles employed as catalysts in a butadiene partial hydrogenation reaction. In this study, we introduce some experimental evidence indicating that subsurface Pd hydride species are governing the reactivity of this reaction. In particular, we detect that the extent of formation/decomposition of PdHx species is very sensitive to the Pd nanoparticle aggregate dimensions, and this finally controls the se

The residual stress generated during heat treatment of nickel-base superalloys will affect their service performance and introduce primary cracks.

Abstract:

Molybdenum is one of the major alloying elements in TiAlbased alloys for high-temperature structural applications developed over the last decades. This is due to its stabilising effect on the (βTi) phase at high-temperatures, which crucially improves the hot-workability of such alloys. For further alloy development, an exact knowledge of the phase equilibria in the Ti–Al–Mo system is essential. However, there are still uncertainties and inconsistencies related to the ternary phase diagram. In this study, a series of ternary alloys was produced and heat-treated between 700 and

Abstract:

The annealing process of cold-rolled ferrite/pearlite steel involves numerous metallurgical mechanisms as recovery/recrystallization of deformed phases, ripening of carbide microstructure, and austenite transformation in the intercritical domain. The interactions between these mechanisms govern the morphogenesis of the transformed austenite microstructure and, thus, the final properties of the steel. This paper demonstrates that high energy X-ray diffraction (HEXRD) on synchrotron beamline offers the unique possibility to follow concomitantly these mechanisms in situ during a single experiment

Abstract:

Resumen Aunque las enfermedades transmisibles afectan nuestros cuerpos, ocurren en una sociedad que las interpreta y dota de significado, y cuyos individuos causan o evitan. La inmunidad de rebaño permite lograr una protección del cuerpo, sin embargo, para su sustentabilidad, se requiere de cambios en la manera cómo las personas interpretan y responden a la enfermedad, de transformaciones culturales que permitan desarrollar conocimientos, hábitos y destrezas que hagan factible y sostenible la inmunidad de rebaño. La cultura de rebaño permite a los individuos protegerse y restringir su libertad

Abstract:

Product endorsement has become a common marketing method. Many companies hire a famous person to act as the spokesman for the product and brand. They want to use the celebrity’s fame and attractiveness to promote their products and brands. However, is every celebrity suitable to be the spokesman for a product? In addition, in the era of advanced technology, whether the comments on the Internet and the credibility of the spokesman affect consumers’ purchase intention through herd behavior. And whether the credibility of the spokesman and the degree of source fit (the degree of fit between the s

Abstract:

This study investigated the influence of BFFSP on the thermohydraulic performance of a SATHEC(s) using a novel computational approach. The novelty lies in the detailed exploration of the interplay between BFFSP, MFRT, and key performance parameters. Unlike prior studies, which often focus on a limited range of operating conditions, this work employs a comprehensive parametric analysis encompassing two BFFSPs (95 mm and 125 mm) and four MFRTs (0.1, 0.3, 0.5, and 0.7 kg/h). This extensive analysis provides a deeper understanding of the trade-off between the HTRFR enhancement and PDP associated w

Abstract:

The blue sheep and Himalayan thar were counted using the vantage count method to obtain population and demographic status in Dhorpatan Hunting Reserve, western Nepal between April and May of 2021. We used binoculars (Olympus 10 × 50 and Nikon 10 × 42) and spotting scopes (Nikon 20–60 × 75 and Bushnell 20–60 × 65) for identifying the animals into class and sex categories. A total of 1290 blue sheep were counted in six hunting blocks of DHR with an apparent density of 2.2 animals/km2 in 79 herds (mean heard size: 16.33 ± 1.53). Maximum numbers of blue sheep were recorded from Dogadi (n=361) and

Abstract:

Four billion people suffer from lack of clean water at least one month of the year.[1] This critical water shortage applies not only to the supply of potable water, but also to water for use in industrial, agricultural, and energy applications. While water resources like seawater are abundant, hardly any water resource is clean enough for direct use. Desalination provides a methodology to render unusable waters from such water resources fit for use. An innovative and particularly energy-efficient electrochemistry-based approach is the Desalination Battery (DB), which stores the energy input du

Abstract:

Abstract As pigs grow, their intestinal microbiome evolves until establishing a stable rich and diverse microbial population (climax community) to maintain the health and growth performance. This evolution (microbial succession) is in fact a multifactorial phenomenon involving environmental parameters (farm practice measures, heard health status, drug use), host (genetics, immune system, biomarkers), sow (milk, colostrum, vaginal, and rectal microbiome) and nutrition. The multifactorial nature of microbial succession and the consequence disruption results in a considerable variation in the pig

A study to ascertain the heard structure of breeding does of small holder goat production system was conducted in Kano using l5 goat herds selected at random in 3 villages.A total of 250 breeding does were involved. The results indicate that parity of does in the observed herds ranged from one to ten.Twelve percent of the does within the age range, 5-25 months were yet to kid for the first time.In the herds, does that did not kid at least once, up to the age of 25 months were culled. However, majorities of the does were in their 2nd and 3rd parities and within the age range of 12-25 months. Tw

Abstract:

Abstract Although communicable diseases affect our bodies, they occur in a society that interprets and gives them meaning. Herd immunity provides the body protection; however, long-term protection requires shifts in the way people interpret and respond to disease, cultural transformation that enables the development of the knowledge, habits and skills that make herd immunity feasible and sustainable. Herd culture allows individuals to protect themselves and restrict their liberty in order to protect others; it is a form of exercising positive liberty and a necessary complement to herd immunity
