A Review Of The Linear Response Function In Condensed Matter Physics And Their Application In Some Elementary Processes

Linear response theory in quantum theory with its linear response function and its quantization process has been formulated. The relation between the linear response function with its generalized susceptibility, its symmetry properties, and its analyticity has been studied. These properties produce the dispersion relation or Kramers-Kronig relation. The explicit form of the quantum response function and generalized susceptibility also been reviewed. Applications of linear response functions have been described for three elementary processes. The process discussed is the magnetic field disturbance in the magnetic system that generates magnetic susceptibility, and the electric field disturbance in the electrical system that generates electrical conductivity tensor and the ferromagnet Heisenberg that generates its generalized susceptibility.
A hybrid method technique for design and optimization of Formula race car exhaust muffler

In this work a multilevel Computational Fluid Dynamics (CFD) analysis has been applied for the design of a Formula race car exhaust muffler with improved characteristics of sound pressure level (SPL) and fluid dynamic response. The approaches developed and applied for the optimization process range from the 1D to fully 3D CFD simulation, exploring hybrid approaches based on the integration of a 1D model with 3D tools. Modern mufflers typically have a complex system of chambers and flow paths. There are a variety of sound damping and absorbing mechanisms working to quiet the sound flowing through a muffler and piping system. Two calculation methods were selected for this study. The muffler has a complex inner structure containing perforated pipe and fiber material. Computer-aided design (CAD) file of the muffler was established for developing Finite Element Analysis (FEA) model in AVL BOOST v2017 and another commercial advanced design software (SolidWorks 2017). FEA model was made to monitor the flow properties, pressure and velocity. After the model was verified, sensitivity studies of design parameters were performed to optimize the SPL of the muffler. The software analysis results are included in the paper. Recommendations are made for obtaining smoother SPL curves for various measurement methods.
Effect of surface pre-oxidation on hydrogen permeation in alpha titanium

The effect of a specific oxidation treatment, to which a titanium specimen was subjected, on the permeation of hydrogen through the titanium specimen was studied. The oxidation treatment involved the maintenance of the specimen in an oxygen atmosphere at a temperature of 270 C for a time of four hours. It was found that the oxidation treatment has the effect of decreasing the permeation rate. However, the first power pressure dependency is not affected.

Employees’ emotional reactions to digitally enabled work events

ABSTRACT Digital technologies are a ubiquitous presence in our lives. Employees can experience a constant bombardment of digital messages, leading to challenges such as work overload, feelings of uncertainty, invasion, and burnout. Employees and organisational leaders are faced with multiple decisions everyday in technology-pervasive environments. Even in the early 1980’s it was recognised that decision-making environments, and the technology within these environments, were having a large impact on decisions and how they are made. This paper presents a scoping review exploring current research on emotional reactions of employees to digitally enabled work events. Utilising Affective Events Theory as a lens, we uncover specific factors such as Emotional Dissonance, Support & Connectedness, Task-Technology Fit, Outcome Beliefs, Personality-Technology Fit, Motivators, and Work Environment Changes. These all play an important part in shaping emotional reactions of employees using digital technologies. The effectiveness of digital technology usage both affects, and is affected by, employees’ emotions.
Henry's Law Constants for 2-Azidoethanamine Hypergols: Estimates From a Density Functional Theory/Polarizable Continuum Model

Abstract : Henry's law constants at 298 K [HLC(298)] for four 2-azidoethanamine (EA) hypergols and three aliphatic amines were estimated via a density functional theory/polarizable continuum model (DFT/PCM) method. The four EAs are 2-azido-N,Ndimethylethanamine (DMAZ), 2-azido-N-methylethanamine (MMAZ), 1-(2-azidoethyl)pyrrolidine (PyrrAZ), and 4-(2- azidoethyl)morpholine (MorphAZ), and the three aliphatic amines are dimethylamine, trimethylamine, and 1-methylpyrrolidine. The estimates for the three aliphatic amines are all within a factor of 5 of measured values that have been reported for them, but all are somewhat low. The DFT/PCM-based estimate for DMAZ is about a factor of 2 smaller than an estimate obtained for it from the Environmental Protection Agency's HENRYWIN program and thus supports the reasonableness of the HENRYWIN estimate. In percentage terms, the DFT/PCM-based estimates for MMAZ, PyrrAZ, and MorphAZ are all significantly lower than those obtained from HENRYWIN, but the estimates from both methods suggest that the volatilization of these compounds from water will be negligible. Taken together, the results indicate that HENRYWIN's HLC(298) predictions for EA hypergols merit use as input for modeling their transport through the environment.
The Relationship between High Speed Rail and Tourism

Much research has verified that the active development of the High Speed Rail (HSR) can create business activities and promote tourism growth. However, based on the related research review, there is currently a lack of profound discussion on the development of the overall transportation system and tourism growth in Taiwan, thus, this study intends to discuss this issue and hopes to provide an important reference for future regional development. This study conducts an in-depth investigation of the relationship between HSR and tourism volume. The Difference in Difference (DID) model is used to verify the impact of HSR services on the tourism volume in Taiwan. In addition, the aggregate data of socio-economic variables and the constituent factors of the transportation mode are incorporated. Finally, the possible consequences are described through elastic analysis. The results of this study can be an important reference for the future development of counties and cities.
Solvolyse des lignines : production de synthons aromatiques de faibles masses

Les lignines ne sont pas suffisamment considerees dans les procedes de bioraffinerie. Pourtant, elles sont une source abondante de synthons aromatiques, et elements essentiels de la rentabilite de transformation des lignocelluloses. A ce jour, les perspectives de production de synthons a partir des lignines se heurtent aux reactions de condensations des lignines, limitant leurs conversions en produits de faibles masses. Cette etude nous a permis de cerner les conditions propices a l’hydrolyse et/ou aux condensations grâce a l’etude de differentes lignines modeles soumises aux conditions d’acidolyse. D’une part, les conditions propices a l’hydrolyse des liaisons -O-4 sont l’utilisation d’une catalyse homogene (HCl), pour des temperatures comprises entre 120 et 140°C et une acidite de l’ordre de 0.05 M. A l’inverse, l’emploi d’une catalyse heterogene (Montmorillonite K10) est peu efficace car elle doit s’affranchir des phenomenes d’adsorption du substrat tout en lui permettant d’acceder a ses sites actifs. D’autre part, les reactions de condensation secondaires sont exacerbees par l’emploi de l’argile de Montmorillonite, mais aussi par l’augmentation de l’acidite et de la temperature, elles memes necessaires pour une bonne hydrolyse. La substitution de l’alcool coniferylique par le coniferaldehyde permet de minimiser ces condensations secondaires du fait de sa forte stabilite dans les conditions d’acidolyse. Toutefois, l’incorporation de ce type de precurseur dans les lignines provoque une diminution de la frequence des liaisons -O-4. Cette reduction du potentiel d’hydrolyse des lignines est compensee par l’exacerbation des reactions de retroaldolisation. Pour les condensations primaires, l’acidolyse des lignines pures -O-4 nous permet d’affirmer que celles-ci, constantes face a l’augmentation de la concentration en acide et en nucleophiles aromatiques, seraient plutot de type intramoleculaire.
The origin, experimental basis, and application of the standard interview method: An information‐gathering framework

Abstract Objectives The standard interview method (SIM) is a guidance framework for information gathering interviews. This article describes the purpose, scope, origin, experimental basis, and practical application of the SIM. It provides an informative overview of developments to date for psychologists and researchers within the behavioural sciences, as well as for practitioners who might use the SIM. The SIM contains core evidence‐based components but is otherwise open to tailoring and modifications to suit a variety of interviewing purposes such as policing, justice, education, and business. It provides an interview structure and exemplar dialogue, aligned with research into best‐practice interview technique. Method A detailed overview of the SIM's interview phases, instructions, and exemplar dialogue is provided. The basis for these elements is explained in terms of the experimental and qualitative research that has informed their development. Results The SIM provides evidence‐based guidance for investigative interviewers, and numerous versions have been created to suit different investigation types, interviewee groups, and jurisdictional or organisational requirements. It is continually refined as new findings from experimental research around best‐practice interviewing emerge. Conclusions Rather than a single entity or completed product, the SIM represents a dynamic evolution of research, collaboration, and testing. Its flexible nature will allow it to keep pace with the ever‐progressing knowledge base that informs interview protocol and guidance development, and adapt to local cultures, legislation, processes, and systems of operation.
An ES-MITC3 Finite Element Method Based on Higher-Order Shear Deformation Theory for Static and Free Vibration Analyses of FG Porous Plates Reinforced by GPLs

An edge-based smoothed finite element method (ES-FEM) combined with the mixed interpolation of tensorial components technique (MITC) for triangular elements, named as ES-MITC3, was recently proposed to enhance the accuracy of the original MITC3 for analysis of plates and shells. In this study, the ES-MITC3 is extended to the static and vibration analysis of functionally graded (FG) porous plates reinforced by graphene platelets (GPLs). In the ES-MITC3, the stiffness matrices are obtained by using the strain smoothing technique over the smoothing domains created by two adjacent triangular elements sharing an edge. The effective material properties are variable through the thickness of plates including Young’s modulus estimated via the Halpin–Tsai model and Poisson’s ratio and the mass density according to the rule of mixture. Three types of porosity distributions and GPL dispersion pattern into the metal matrix are examined. Numerical examples are given to demonstrate the performance of the present approach in comparison with other existing methods. Furthermore, the effect of several parameters such as GPL weight fraction, porosity coefficient, porosity distribution, and GPL dispersion patterns on the static and free vibration responses of FG porous plates is discussed in detail.
To Bribe or Not in a Procurement Auction under Disparate Corruption Pressure

We examine a (large) manufacturer’s bribery decision (to bribe or not to bribe) arising from a procurement auction under “disparate corruption pressure” when another (small) manufacturer is known to offer the auctioneer (i.e., the intermediary) a bribe in exchange for the “right of first refusal. ” We discover that the large manufacturer should refuse to pay bribes at all times in order to prevent from leaking its private cost information to the small manufacturer and prevent from intensifying the competition. However, even when the large manufacturer is disadvantaged for refusing to bribe, we show that it can benefit from this corrupted auction when the difference in production efficiency or the bribe is high so that the “positive force” (i.e., cost advantage) derived from the right of first refusal dominates the information disadvantage. Hence, under a specific condition, the large manufacturer has no incentive to expose the collusion between the intermediary and the corrupt manufacturer. Such a “silence tactic” provides a plausible explanation for the prevalence of corrupt auctions in practice.
Complexation and bonding studies on [Ru(NO)(H2O)5]3+ with nitrate ions by using density functional theory calculation

Complexation reactions of ruthenium–nitrosyl complexes in HNO3 solution were investigated by density functional theory (DFT) calculations in order to predict the stability of Ru species in high-level radioactive liquid waste (HLLW) solution. The equilibrium structure of [Ru(NO)(NO3)3(H2O)2] obtained by DFT calculations reproduced the experimental Ru–ligand bond lengths and IR frequencies reported previously. Comparison of the Gibbs energies among the geometrical isomers for [Ru(NO)(NO3)x(H2O)5−x](3−x)+/− revealed that the complexation reactions of the ruthenium–nitrosyl complexes with NO3− proceed via the NO3− coordination to the equatorial plane toward the Ru–NO axis. We also estimated Gibbs energy differences on the stepwise complexation reactions to succeed in reproducing the fraction of Ru–NO species in 6 M HNO3 solution, such as in HLLW, by considering the association energy between the Ru–NO species and the substituting ligands. Electron density analyses of the complexes indicated that the strength of the Ru–ligand coordination bonds depends on the stability of the Ru species and the Ru complex without NO3− at the axial position is more stable than that with NO3−, which might be attributed to the difference in the trans influence between H2O and NO3−. Finally, we demonstrated the complexation kinetics in the reactions x = 1 → x = 2. The present study is expected to enable us to model the precise complexation reactions of platinum-group metals in HNO3 solution.
Harnessing social and collaborative tools in digital disaster response work: Implications for design and practice

This paper explores the implication of the use and appropriation of collaborative technologies in digital disaster response. Using a virtual ethnographic approach, we studied the work of Humanity Road through participant observation of seventeen response operations across thirteen countries for seventeen months. The results identify critical areas where collaborative technologies have been successfully deployed for organising disaster responses. Our analysis offers insights into the areas where these technologies have facilitated or hindered the capacity of cooperative work during response operations. We conclude by suggesting implications for design and practice.
The Role of Brand Page Experiences on Consumer Engagement in Social Media

This study develops and empirically tests a comprehensive model of consumers' brand page experiences that illuminates dynamics among perceived values (practical value, stimulation, enjoyment, and social identification), brand page engagement dimensions (cognitive engagement, affective engagement, and behavioral engagement) and brand loyalty. An online survey was employed for data collection. We collected 358 usable responses for data analysis. Structural equation modeling results show that three dimensions of perceived values (practical value, perceived enjoyment, and social identification) positively affect brand engagement dimensions, while perceived stimulation affects affective engagement only. As for the roles of brand page engagement, affective and behavioral engagement positively influence brand loyalty. This study demonstrates how consumers' perceived values of brand page experience influence each dimension of brand page engagement and how each dimension has a different impact on brand loyalty. The results of this study provide substantive contributions to the consumers' brand page experience and engagement literature and brand page management on social media for developing brand loyalty.
Industry Policies, Logistics 4.0 and Competitiveness Development of Manufacturers in Thailand’s Eastern Economic Corridor

A qualitative study is employed to explore factors encouraging manufacturers in Thailand’s Eastern Economic Corridor to enhance their competitiveness by means of logistics 4.0. There are four research issues needed to be addressed in this study: (1) What is the logistics situation of manufacturers in the Eastern Economic Corridor (EEC) areas; (2) What are the roles of technology changes and transfers in adoption of technology-related logistics system for competitiveness; (3) What are the impact of government policies on manufacturers and its logistics system; and (4) What extent should the government support logistics 4.0 and competitiveness of manufacturers within the EEC area. Data were collected by means of in-depth interview from thirty-five participants at top and middle management levels in firms across EEC regions. Content analysis was employed to analyze data. The findings show that the government’s policies have significant impacts on manufacturers within the EEC area, especially the policies that bridge technology transferring gaps (i.e., funding for human development and logistics consultants to assist of individual organizations on some specific issues). In contrast, the incentives given to new investors in the EEC area discourages competitive advantage of existing manufacturers within the areas. The adoption of information technology in the organization is widely found in most of the organizations; however, there are limitations regarding logistics automations and funding to upgrade the advanced equipment for competitive development.
Um panorama das práticas comunitárias da terapia ocupacional na América Latina

Introducao: A historia recente da terapia ocupacional (TO) mostra, em escala global, grande preocupacao com questoes sociocomunitarias que afetam as ocupacoes e o cotidiano das pessoas. Terapeutas ocupacionais, atuando na sociedade e atendendo a suas demandas, buscam promover inclusao, emancipacao e participacao na vida sociocomunitaria das pessoas. Nao obstante, estudos latino-americanos sobre as intervencoes comunitarias de terapeutas ocupacionais ainda sao escassos, o que sugere pesquisas mais especificas sobre os contornos e fundamentos dessas intervencoes. Objetivo: Investigar a producao de terapeutas ocupacionais sobre as praticas comunitariasem terapia ocupacional, priorizando os conceitos utilizados para fundamentar essas intervencoes, na America Latina, entre 2006 e 2016. Metodo: Uma revisao de escopo foi realizada nos idiomas portugues e espanhol.

Recomenda-se maior aprofundamento teorico e metodologico dos modelos identificados para a consolidacao do campo.
Tasa de política monetaria en México ante los efectos de Covid-19

(Monetary policy rate in Mexico due to the effects of Covid-19) The economic crisis feeded by Covid-19 has produced supply and demand shocks that affect the potential product and consumer preferences, an impact that suggests that the neutral real interest rate was modified and, therefore, the real interest rate should be adjusted so as not to generate a deeper economic contraction in Mexico. We estimate the value of the neutral rate using the Laubach and Williams method, based on the Kalman filter, and confirm the results with a cointegrated vector of autoregressions (CVAR) model. The results show that the neutral real rate, theoretically consistent with the full employment rate and the inflation target in Mexico, is reduced to 0.1% and the nominal to 3.1%, which suggests the existence of enough room for an expansionary monetary policy that allows facing the crisis and boost economic activity for at least three years.
Electrochromic Performances of Poly(Azure A) Films from Digital Video-Electrochemistry (DVEC)

Poly(Azure A) (PAA) films doped with sodium dodecyl sulfate (SDS) were grown on transparent indium tin oxide (ITO) glass substrates by cyclic voltammetry. The electrochromism of PAA was investigated by digital video-electrochemistry (DVEC). DVEC consists of the acquisition of sequential digital images during the electro-stimulated changes of PAA color. The evolution of red, green, and blue (R, G, B) colors intensity (I) of analyzed pixels provides enough sensitivity to detect changes of some nmol cm−2 of electroactive centers. Besides, the different time evolution of these color intensities can serve to discern among different electroactive centers activated in the polymer. For the first time, contrast, coloration efficiency, and bleaching times of PAA are calculated by DVEC. The coloration efficiencies were between 15–25 cm2 mC−1 with short response times for the bleaching process between 2.9 and 5.5 s. PAA has good electrochromic performances to be used in electrochromic devices. Our present work provides an important insight into the design principles for a practical application of DVEC to characterize electrochromic devices in light-controlled conditions allowing us to find the best performances of these materials.
