4E Analysis of Power and Water Cogeneration Plant based on Integrated MED-TVC and RO Desalination Units
Authors: VAZİNİ MODABBER Hossein , KHOSHGOFTAR MANESH Mohammad Hasan
Published: November 2020

In this study, integration of RO desalination unit with power and water cogeneration plant located in Qeshm Island in Iran has been investigated. The desalination unit exists in this plant is MED-TVC type. In this regard, energy, exergy, exergoeconomic, and exergoenvironmental (4E) analyses have been performed by developing a computer code using Matlab. Validation of thermodynamic data has been performed through comparing the results of modeling by Matlab with the simulation done in Thermoflex software and the real data gathered from the Qeshm cogeneration plant. The results show the acceptable accuracy of thermodynamic modeling. The exergoenvironmental analysis has been conducted based on Life Cycle Assessment (LCA). In this regard, the weight function of TVC is proposed in this paper based on technical data in different nominal sizes in order to estimate the environmental impacts of this component. The cogeneration plant produces 25.7 MW power, consuming 6 kg/s steam can lead to production of 51.7 kg/s desalinated water. The gained output ratio (GOR) is about 8.7 for the MEDTVC unit. The performance ratio (PR) of RO desalination unit which is added to the downstream of MED-TVC has been calculated about 0.5. Integrating RO desalination unit with MED-TVC enhances the production of fresh water by 255.132 ton per hour.Exergetic efficiency, total cost rate of the system and total environmental impact rate of the system has been calculated 46.86 %, 64.01 $/min and 29.49 pts/min, respectively. Since the largest share of exergy destruction rate of the system belongs to the gas cycle and also Qeshm Island has a warm and muggy climate, adding a chiller type air cooling system to inlet of air compressor can decrease the power demand of air compressor and fuel consumption of combustion chamber which makes the system more efficient and reduce the cost and environmental impact rate of the system.
The importance of the Debye bosons (sound waves) for the lattice dynamics of solids
Authors: KÖBLER Ulrich
Published: November 2020

For a
number of materials with cubic lattice structure the dispersion relations of
the Debye bosons (sound waves) and of the acoustic phonons along [ζ 0 0]
direction have been analyzed quantitatively. When all phonon modes are excited,
that is, for temperatures of larger than the Debye temperature the dispersion
of the mass-less Debye bosons exhibits a pronounced non-linearity, which is
explained by interactions with the phonon background. For the exponent x in the
dispersion relation ~qx of the Debye bosons, the rational values of
x=1/4, 1/3, 1/2, 2/3 and 3/4 could be established firmly. The discrete values
of x show that there are distinct modes of interaction with the phonons only. It
is furthermore shown that for many materials the dispersion of the acoustic
phonons along [ζ 0 0] direction follows a perfect sine function of wave vector,
which is known to be the dispersion of the linear atomic chain. This dispersion
is unlikely to be the intrinsic behavior of three-dimensional solids. It is
argued that the sine-function is induced by the Debye boson-phonon interaction.
Quantitative analyses of the temperature dependence of the heat capacity show
that the heat capacity can be described accurately over a large temperature
range by the expression cp=c0-B‧T-ε. The
constants c0 and B are material specific and define the absolute
value of the heat capacity. However, for the exponent ε the same rational value
occurs for materials with different chemical compositions and lattice structures.
The temperature dependence of the heat capacity therefore exhibits
universality. This universality must be considered as a non-intrinsic dynamic
property of the atomistic phonon system, arising from the Debye boson-phonon
interaction. The discrete modes of boson-phonon interaction are essential for
the observed universality classes of the heat capacity. Safely identified
values for ε are ε=1, 5/4 and 4/3. The fit values for c0 are
generally larger than the theoretical Dulong-Petit value. Universal exponents
are identified also in the temperature dependence of the coefficient of the
linear thermal expansion, α(T). Since the universality in α(T) holds for the
same thermal energies (temperatures) as for the ~qx functions in the
dispersion of the Debye bosons it can be concluded that the Debye bosons also determine
the temperature dependence of α(T). Our results show that the dynamics of the
atomic lattice is modified for all temperatures by the Debye bosons. Atomistic
models restricting on inter-atomic interactions therefore are neither
sufficient to explain the phonon dispersion relations nor the detailed
temperature dependence of the heat capacity.
Modelling and experimental thermodynamic data of hydroxylic compounds (C1-C6) as a function of temperature

Published: November 2020

Alcohols have a long history of several uses worldwide. Because of their relatively low toxicity compared with other many chemical compounds and ability to dissolve non-polar substances, alcohols can be found into beverages for adults, used as combustion engine fuel, as excipient in medical drugs, as component into personal-care products and in many scientific and industrial applications. One of the key problems of the chemical industry is the lack of available physical properties data for equipment industrial design and improvement of theoretical models for simulation. The present work deals with the modelling and experimental measurement (density and ultrasonic velocity) of thermophysical properties of short chain hydroxylic compounds (C1-C6). Fitting equations were applied to the experimental data in order to correlate for later computer based design. Different derived magnitudes were computed from the experimentally measured density and ultrasonic velocity, due to their importance for theoretical calculations and development of new models. The estimation of the studied properties was made by the application of different theoretical procedures. A wide comparison was made with available open literature, being evident the lack of reliable information in the ranges studied until now.
Universality in the temperature dependence of the heat capacity of magnetic solids
Authors: KÖBLER Ulrich
Published: November 2020

It is shown that the temperature dependence of the heat capacity of the magnetic solids can completely be described by a sequence of universal power functions of temperature. Characteristic for universality is that each power function holds over a finite temperature range and has a rational exponent. The analytical change from one to the adjacent power function is a typical crossover event. Universality reveals that the temperature dependence of the heat capacity is determined by a boson field whereas the absolute values are given by all magnetic and non-magnetic inter-atomic interactions. Universality for temperatures outside the critical range at Tc, i.e. for temperatures for which the phonons dominate the heat capacity has to be characterized as non-intrinsic, arising from interactions of the phonons with the bosons of the continuous magnetic medium. As we have shown earlier, the bosons of the continuous magnetic solid are essentially magnetic dipole radiation generated via stimulated emission by the precessing spins. We have called them Goldstone bosons. The interactions of the Goldstone bosons with the magnons modify the wave-vector dependence of the magnons. For cubic crystals the dispersions along [ζ, 0, 0] direction are essentially as for the linear spin chain, i.e. one-dimensional. As the different rational exponent values in the temperature power function of the heat capacity show, there exists a number of distinct modes of interaction between the Goldstone boson field and the phonons. The actual exponent depends additionally on the proportion between the magnetic and the non-magnetic energy contributions and therefore changes with temperature. The observed exponents are, however, difficult to interpret.
Resilience in Critical Infrastructures: The Role of Modelling and Simulation
Authors: Foglietta Chiara , Panzieri Stefano
Published: November 2020

Resilience and risk are fundamental concepts for critical infrastructure protection, but it is complex to assess them. Modelling critical infrastructure interdependency helps in evaluating the resilience and risk metrics. We propose the MHR approach as a road-map to model infrastructures and it is implemented using CISIApro 2.0. MHR suggests considering three different layers in each infrastructure: holistic, service and reductionist agents. In this chapter, this framework has been tested in a scenario made of a modern telecommunication network, a hospital ward and a smart factory. The scenario takes into account cyber attacks and their consequences on the components, services and holistic nodes. The proposed framework is under validation within the EU H2020 RESISTO project with good results and in various test-beds.
Risk Analysis in Early Phase of Complex Infrastructure Projects
Authors: Tepeli Esra
Published: November 2020

Infrastructure construction projects are complex with a very long life-cycle, a complex organizational plan, a complex resource management, technical complexities, contractual complexities and macro-environmental factors. The complexity of an infrastructure project leads to the existence of interdependent risks, which are hard to anticipate and control. As the investment is major for these types of projects, the risks and opportunities are critical to the project success or failure, the risk factors need to be identified and analyzed before any decision-making process. While upfront planning is important, not all events and scenarios can be foreseen as the project can take several years to complete and may involve many companies and stakeholders. In this planning stage of the project, a robust risk analysis method is indispensable for identifying and analyzing the major risk and opportunity factors. In this paper, a formalized multi-criteria decision-making process is developed based on a strategic risk analysis in a complex environment: (1) in a very early stage and at a strategic level, (2) before the contracting phase in order to develop a risk allocation plan and negotiate it with the project owner.

Published: November 2020

In this chapter Ag, Ni and Fe nanocolloids synthesized by “green” ultrashort pulse laser ablation of solid metal targets using different pulse energies and liquid media are characterized by different techniques. Optical extinction spectroscopy (OES), micro-Raman spectroscopy (MRS), transmission electron microscopy (TEM) and electron diffraction (ED) were independently used to analyze optical, morphological and compositional properties of the generated nanocolloids. In a deeper way, the stability characteristics of Ag nanocolloids in aqueous solutions with different stabilizers were studied owing to their potential use in biocompatible compounds. Besides, due to their interesting applications, few atoms Ag nanoclusters (NCs) were synthesized using the same ablation technique, analyzing their fluorescent and photocatalytic properties. On the other hand, to expand the characterization of the nanocolloids, their magnetic behavior was inspected for the Ni and Fe by vibrating sample magnetometry (VSM).

Published: November 2020

In the clinical field, 3D Printing producing is a progressive innovation for various applications, specifically on account of its capacity to customize. From bioprinting to the making of clinical items, for example, inserts, prostheses, or orthoses, it is having a significant effect. Given that there are many energizing activities and organizations in every one of these territories today we will present to you a positioning of the best 3D printed orthoses. Dissimilar to prostheses that supplant a non-existent piece of the body, orthoses are clinical gadgets that are made to settle, soothe, immobilize, control, or right a piece of the body. Since every patient is unique, 3D printing is especially appropriate for these kinds of items and gadgets. Requiring an orthotic or prosthetic item likely methods a work concentrated, tedious, and chaotic procedure. For makers, creating great fitting orthotic and prosthetic gadgets is costly and requires profoundly gifted staff. Patients can anticipate that to a lesser degree a hold up should get their gadget, fewer fittings, and improved sturdiness. Developing a comfortable, properly fitting prosthesis is not just a science, it is also an art. 3D printing has the power to take today’s bespoke, artisanal manufacturing process and transform it into a highly repeatable and consistent process, which ultimately results in more effective clinics and better patient outcomes.

Published: November 2020

The primary maxillary second molars usually have three roots. However, an additional root located mesiopalatally is occasionally observed. This study aimed to determine the relationship between a mesiopalatal root of primary maxillary second molars and an abnormal eruption pattern of maxillary second premolars. The study was performed on cone beam computed tomography images taken from 916 children who visited the Dental Hospital of Kyung Hee University from 2010 to 2018. 744 serial cross-sectional cone beam computed tomography images were evaluated. The overall incidence of the mesiopalatal root of primary maxillary second molars was 3.2% (n = 24) and the abnormal eruption pattern of maxillary second premolars was 19.2% (n = 143). Especially, patients with the mesiopalatal root of primary maxillary second molars were significantly more likely to have the abnormal eruption pattern on maxillary second premolars (p = 0.000). The odds of the abnormal eruption pattern of maxillary second premolars with the mesiopalatal root of primary maxillary second molars was about 13 times higher than those without. The eruption pattern of the permanent successor should be carefully observed and treated if the mesiopalatal root of primary maxillary second molar is existent.

Published: November 2020

The aim of this study was to evaluate the association between various predicting tools and Apnea-Hypopnea Index (AHI) to identify children with sleep disordered breathing (SDB). From 5 to 10 years old who came for orthodontic counseling, 61 children, whom had lateral cephalograms, pediatric sleep questionnaire (PSQ) records, and portable sleep monitoring results, were included in this study. A total of 17 measurements (11 distances and 6 angles) were made on lateral cephalograms. The measurements of lateral cephalograms, PSQ scales and portable sleep monitoring results were statistically analyzed. 49 of 61 (80%) patients showed AHI > 1, which suspected to have SDB and their mean AHI was 2.75. In this study, adenoid size (A/N ratio), position of the hyoid bone from mandibular plane, gonial angle, and PSQ scale were related to a higher risk of pediatric SDB. Also, oxygen desaturation index (ODI) and snoring time from sleep monitoring results were statistically significant in children with SDB using Mann-Whitney test (p ＜ 0.05).
In conclusion, evaluation of hyoid bone position, adenoidal hypertrophy, gonial angle in lateral cephalogram, and PSQ scale was important to screen out potential SDB, especially in children with frequent snoring.

Published: November 2020

The aim of this study is to compare cariogenic characteristics of fluoride-sensitive Streptococcus mutans [fluoride-sensitive (FS) S. mutans ] and fluoride-resistant Streptococcus mutans [fluoride-resistant (FR) S. mutans] in the presence of sucrose, and to evaluate its effect on cariogenic biofilm formation. S. mutans ATCC 25175 was continuously cultured in trypticase soy broth (TSB) containing NaF (70 ppm) for 40 days to generate FR S. mutans . FS and FR S. mutans were inoculated in TSB with or without 2% sucrose, and optical density and pH were measured every hour. An oral biofilm was formed using saliva bacteria and analyzed through confocal laser scanning microscopy and CFU count. Finally, the expression of glucosyltransferases genes of both S. mutans was investigated through RT-PCR. FR S. mutans exhibited slower growth and lower acidogenicity in the presence of sucrose compared to FS S. mutans . Both cariogenic and single species biofilm formation was lower in the presence of FR S. mutans , along with reduced number of bacteria. FR S. mutans showed significantly low levels of gtfB, gtfC, and gtfD expression compared to FS S. mutans . On the basis of results, FR S. mutans may be less virulent in the induction of dental caries.
The effects of adsorbent mass using red brick powder on the results of biogas purification
Authors: Wahyudi Slamet , Nurahmad Efendi , Faizal Ahmat
Published: November 2020

Biogas is produced by the digestion of organic waste by anaerobic bacteria. However, the application of raw biogas is not effective because it consists of impurities such as carbon dioxide (CO2), hydrogen sulfide (H2S), water vapor (H2O), and other impurity gases. Physical Adsorption is the simplest method of immobilization of biomolecules such as CO2 which is attached to the surface through the weak bonds like van der Waals forces. One of the physical adsorption means to reduce CO2 levels in biogas is to use brick powder. Increasing of brick powder adsorbent mass caused the decrease of CO2 concentration in the biogas purification. Brick is a porous material containing SiO2 - Al2O3, so it has the ability to form Van der Waals bonding forces with CO2. The goal of this research is to determine the efficiency of brick powder as a purification adsorbent to reduce of CO2 levels using the 23 factorial design method. The application of 200 and 400 grams brick powder adsorbents, with the biogas flow rate of 1 and 2 liters/minute, was researched at intervals of 5 and 20 minutes, for the CO2 concentration data and heating values of biogas. Gas Chromatography (GC) was used to determine the concentration of adsorption gases, especially CO2 and CH4. The results showed that the biggest efficiency reduction in CO2 concentration is 59.28%.

La poética dramática desde una perspectiva cuantitativa: la obra de Calderón de la Barca
Authors: Ehrlicher Hanno , Lehmann Jörg
Published: November 2020

El desarrollo de métodos computacionales cuantitativos para llevar a cabo un análisis estructural y formal de textos dramáticos es relativamente reciente en las Humanidades Digitales. En este artículo estudiaremos, a través de este enfoque cuantitativo, algunos aspectos de la obra de Calderón de la Barca. Para llevar a cabo el análisis se hará referencia a las poéticas dramáticas contem-poráneas de la Comedia nueva española, que se contraponen a las reglas establecidas en el teatro clásico francés, como las unidades de acción, lugar y tiempo, las reglas de distribución de los personajes, la convención sobre la separación de los estados sociales y sobre la composición en general. Las características cuantitativas se explorarán en los dos géneros dramáticos más empleados por Calderón, la comedia y el auto sacramental, detectando así los patrones y estructuras formales del autor.
Measuring difficulties in choosing an upper secondary school: Validating of the Parental Expectations, Confusion, Anxiety and Suitability Scale (PeCAS Scale)
Authors: Boerchi Diego
Published: November 2020

This study was aimed to develop a new questionnaire, on school choice difficulties, with a limited number of items and scales to make it suitable both for pre-screening on large numbers of students and studies which use batteries of many tests. The PeCAS Scale assesses four dimensions, Parental expectations, Confusion, Anxiety, and Suitability, which could be considered the most essential according to previous literature. In total, 1495 students participated in the study. Both exploratory and confirmatory factor analysis supported a four-dimensional factor structure. Reliability and concurrent validity, concerning the process of choosing a school and a scale on career exploration, were also adequate.
Prevalence, gender and age differences of dating aggression among Italian adolescents
Authors: Cuccì Gaia , O’Leary K. Daniel , Olivari Maria Giulia , Confalonieri Emanuela
Published: November 2020

The present study represents an effort to expand and deepen the scant literature on Adolescent Dating Aggression (ADA) within the Italian context; adolescent dating aggression is a public health issue of interest due to its increasing frequency among adolescents. The prevalence of verbal-emotional and physical ADA was examined as well as gender and age differences in a sample of Italian adolescents. Participants included 436 adolescents (47.7% males; 52.3% females) living in northern Italy, aged 16 to 18 years (M = 17.11). Participants completed the Conflict in Adolescent Dating Relationships Inventory measuring abusive behaviors between adolescent dating partners. Non-parametric analyses were computed. Verbal-emotional ADA perpetration and victimization were much more common than physical ADA perpetration and victimization. Females reported higher levels of verbal-emotional and physical ADA perpetration than males. To fully investigate gender differences single behaviors were analyzed and described. Finally, age differences emerged only for perpetrated verbal-emotional abuse with such aggression being highest at age 18. This research suggests that in order to prevent the onset of dating aggression in teens in northern Italy, prevention programs may need to begin earlier than previously provided in junior high school. Another core conclusion is that physical aggression against partners is a problem for both males and females, thus intervention for the empowerment of interpersonal skills are needed.
Adult attachment dimensions: Differential effects on physiological and subjective response during the recollection of childhood memories
Authors: Congia Pierpaolo
Published: November 2020

The aim of this study was to explore the relationship between adult attachment dimensions and emotional response induced by the recall of potentially painful memories from childhood. A convenience sample of 100 women responded to an interview that focused on experiences with their caregivers during childhood, and a control interview, in counterbalanced order. Skin conductance level (SCL), heart rate (HR), heart rate variability (HRV), as well as subjective distress measures were collected. Results from generalized linear mixed model indicated that individuals high in avoidance showed a pattern of SCL increase from baseline that persisted during rest phases regardless of the topic addressed. Attachment dimensions did not affect HR, neither alone nor interacting with the interviews content, whereas baseline resting vagal tone was the most important factor. No attachment dimensions effects were observed on subjective measures of emotion; the time-varying vagal tone during rest phases did not moderate their relationships. Limited evidence was observed in support of the hypothesis that attachment Avoidance and Anxiety are associated with distinct physiological regulation profiles during the recall of potentially painful childhood memories.
Expressive suppression within task-oriented dyads: The moderating role of power
Authors: Balzarotti Stefania , Cesana Stefano , Biassoni Federica , Ciceri Maria R.
Published: November 2020

Although research has so far consistently revealed that using suppression to regulate emotions has adverse personal and social effects, it has been argued that suppression may be less detrimental within non-close relationships. In the present work, we examined the effects of experimentally induced suppression on expressive behavior, emotional experience, and social outcomes within task-oriented interactions between individuals randomly assigned to high/low vs. equal power positions. Eighty-eight participants were randomly paired with a partner of the same gender (forty-four dyads). After being randomly assigned to one of four experimental conditions created to manipulate suppression use and power, each dyad was asked to complete two problem-solving tasks. The results showed that the participants who were assigned to the subordinate (low-power) role and who used suppression to regulate their emotions reported more negative emotional experience than did individuals assigned to equal-power roles, as well as more inauthenticity and diminished feelings of rapport compared to subordinates who freely expressed their feelings. Moreover, we found that the use of suppression also influenced participants assigned to the manager (high-power) role, as they exhibited less positive behavior, reported less positive experience and lower feelings of rapport when interacting with a partner asked to suppress. When individuals were assigned to equal power roles, the participants instructed to use suppression reported lower levels of positive emotions than did their partners as well as higher feelings of inauthenticity compared to uninstructed participants. Overall, these findings seem to suggest that suppression may impair task-oriented interactions between high/low power individuals more than interactions between individuals sharing equal power.
Mother to mother: Mothers’ social comparison-based emotions on social networking sites
Authors: Tosun Leman Pinar , Öztürk Ahu , Özdemir Gamze
Published: November 2020

Social networking sites (SNSs) are platforms where people make social comparisons very frequently, and because of those comparisons, they have the potential for evoking a wide range of emotions. According to typology of social comparison-based emotions, the emotions felt after social comparisons may vary according to the direction of comparison (upward vs. downward) as well as the internal process that triggered by those comparisons (assimilation vs. contrast). The current study aims to examine the mothers' emotions they felt after social comparisons they make with other mothers on the SNSs, and search out the usefulness of using the typology of social comparison-based emotions in examining those emotions. For this purpose, an online survey was conducted on 42 mothers between the ages of 20 and 48, who have been a member of SNSs for at least six months. Mothers responses to two open-ended questions; one is about the emotions they feel after upward comparisons, and the other is about the ones that they felt after downward comparison they made with other mothers on SNSs, were examined through thematic analyses. The results pointed out that the emotion classification offered in Smith’s theory might be useful in examining the social comparisons on SNSs made by mothers, with the addition of some new categories. Specifically, it was found that some mothers feel doubts about the credibility of information in other mothers’ posts, and some others denied they are emotionally influenced by social comparisons. Another interesting finding was that mothers reported to feel assimilative and contrastive emotions simultaneously.
Poetic effects and visuospatial form: a relevance-theoretic perspective
Authors:   , Pinder Daniel William
Published: November 2020

Sperber and Wilson (1995:222) posit the term poetic effect for the peculiar effect of an utterance which achieves most of its relevance through a wide array of weak implicatures. Crucially, the input to pragmatic processing, which prompts the derivation of a poetic effect, is achieved via some stylistically pronounced linguistic feature: for example, a repeated lexical item, a peculiar syntactic form, a piece of alliteration, and so on. However, what has never been considered to any great depth from a relevancetheoretic perspective is how unusual elements of visuospatial form might also impact upon the reader’s basic understanding and wider interpretation of a given poetic text in ways that result in the derivation of specialised poetic effects. Therefore, the thesis posits a relevance-theoretic account of the cognitive-pragmatic effects of short linelength and line divisions, when employed and interpreted within complex forms of poetry. The account is split into two hypotheses relating to short line-length and line divisions respectively. Hypothesis 1 states that the use of short line-length leads to the majority of the text’s lexical material being perceived in a much slower, and therefore intense fashion, which consequently causes the lexical and encyclopaedic entries that such material links to within the mind to remain active for relatively longer periods of time. During such extended periods of lexical and encyclopaedic activation, literary readers are encouraged to inferentially process the text’s explicit-propositional content in relation to a range of further items of encyclopaedic-contextual material, which can give rise to arrays of additional contextual effects of a weakly implicit and therefore poetic nature. Hypothesis 2 states that line divisions are often intentionally utilised in poetic texts by writers in order to visuospatially separate integral syntactic units upon the page. This can encourage readers to pause and briefly consider, upon an anticipatoryhypothetical basis, the various possible pragmatic extensions of the text’s momentarily incomplete logical and propositional status, pre-line division as it were. The various pragmatic extensions may be formulated as arrays of weak explicatures, which for some readers may achieve poetic effects (in the specialised relevance-theoretic sense of the term). The process effectively constitutes the visuospatial equivalent of a deliberate ‘pause for effect’, which triggers a considerable degree of further inferential processing, and provides a distinct communicational ‘reward’ primarily at an explicit-propositional level.
Revisiting image theory: decision styles, temptations and image theory’s compatibility test
Authors:   , Müller Alexander
Published: November 2020

This thesis project revisits the compatibility test, Image Theory's screening process to form decision choice sets, and considers its elements and mechanisms in the light of three aspects: first, it investigates how the affect heuristic influences the compatibility screening. In this context, the claim of earlier research that only criteria violations are considered during the option screening process is reconsidered; second, a structural model is evaluated establishing links between a decision-maker's decision styles and the variables defining the compatibility test; and third, a neural network is created and tested to predict even irrational choice of decision-makers for a specific screening situation and based on their compatibility test in- and outputs. 741 participants of two populations were administered three online questionnaires to collect required data. 40 questionnaire items have been used to identify the participants decision styles. The participants were tasked to select companies as potential acquisition targets and, thus, performed a compatibility test based on criteria and their importance weights provided by the researcher. Companies met and failed to meet the criteria to differing extent. Two temptation alternatives that outperformed all other companies in the most important criteria multiple times and failed to meet all others were administered to the participants. Based on what companies were selected, the participants rejection threshold and their inconsistent choices were determined. The research provides evidence that the claim of earlier research that Image Theory's compatibility screening process relies only on criteria violations is untenable. Further, a structural equation model was confirmed establishing links between participants' decision styles and the variables defining their compatibility screenings. Eventually, a neural network was generated, trained and tested that correctly predicted with close to 90% reliability a participant's choices, even the objectively irrational ones. It is recommended that future research further develops the idea of neural networks mimicking human decision behaviour.

The optical phonon spectra for ZrH1.7 (containing 0.2% C) and PdH0.7 are measured at room temperature and low temperature (97 K) -with beryllium filter detector spectrometer adjacent to the heavy water pile in the Institute off Atomic Energy. The results show that: (1) Optical phonon Energy Level for ZrH1.7 is equal essentially spacing, the width of energy level essentially does not change with T i.e. the anharmonicity of optical phonon. is weak and it obeys Einstein harmonic model. (2) The second optical phonon energy level spacing for PdH0.7 is about 8 meV larger than that of the first level spacing, and the width of its optical phonon energy level changes from 38 meV at room temperature to 20 meV at 97 K. This means that the optical phonons which ply important role in supercondectivity of PdHx exhibit significant anharmonicity.

After bombarding the Mo (111) surface with nitrogen ions of the energy of 1 keV and the beam current of 6 μA for 15 min, a very strong Auguer peak of nitrogen appeared in AES. The LEED observation showed that surface structure was disordered after annealing in the temperature range from room temperature to 450℃. The stable square pattern appeared at 562℃ can be interpreted in terms of c(3×1)-N, O overlayer structure on the Mo (433) faceting planes.
A STUDY ON THE RELAXATION MECHANISM OF THE QUASI-POSITRONIUM

Published: November 2020

In our theoretical approach, the relaxation mechanism of the quasi-positronium (qPs) in alkali halides has been studied. It can be shown that the electronic cloud polarization in the medium results in the screening effect on the Coulomb potential of electron-positron pairs, so as to lead to the relaxation phenomena. Because the mean distance between the electron and positron in qPs is of the order of the lattice constant in alkali halide crystal, the Toyozawa's Hamiltonian in which only long range interaction between a charged particle and the medium is considered, could not be fitted in with the case of the qPs. So we try to make "the short range force correction" to the interactive Hamiltonian by using phenomenological method. Then we can solve the total Hamiltonian into the effective Hamiltonian of the qPs by means of the method which had been used to treat the exciton by Ku Shih-wei. It is shown that the result of variational treatment of the effective Hamiltonian is in good agreement with the experimental data, so the relaxation mechanism of qPs can be interpreted quantitatively.

Authors: ZHANG CHENG-FU  ,   北京大学物理系
Published: November 2020

In this paper, the effects of collision on the dispersion equation of plasma are discussed under two kinds of collision models (BGK model and LB model). Analysis shows that the main effect of collision is to change the usual dispersion function Z(ξ) into a generalized one W(ξ,ν). The properties of W function have been analysed and compared for two models. The effects of collision on low frequeny drift wave (local mode) and ion-acoustic wave have been discussed. It is shown that LB model is not only more reasonable physically than BGK model, but also more simple in calculation and expression.

Published: November 2020

The vacancy-concentration effect on the vacancy-migration-energy and the behaviour of divacancies were considered Using a formula derived for the vacancy current in bcc metals. It turns out that the vacancies will migrate in the direction of increasing concentration, if the concentration is over some critical value which we have determined.This method can also be used for other metals.

The InP(l00) (4×2) reconstructed surface prepared by argon ion bombardment and post annealing under phosphorus pressure has been investigated by LEED, HREELS and UPS. It was found by HREELS that the forming of surface In-H and P-H bonds during hydrogen exposure happened almost simultaneously. By measuring the UP spectra using polarized light sources, it can be verified that the dangling bond states of surface P atoms do not possess the symmetrical characteristic with respect to the two basis vector directions of surface unit mesh. It could be deduced from the above evidences that there must exist some In vacancies on the In-rich InP (100) surface, and the dangling bonds of those P atoms which are located next to the In vacancies orientate off their normal directions. We propose here a missing row-dimer model for the atomic arrangement of InP (100) (4×2) stucture, which could explain the observed experimental qualitatively and might be used as a working model for seeking a precise surface structural model.

Published: November 2020

An optogalvanic spectroscopy method for study of atomic mercury metastable level is reported. The experiments are described in which the mercury discharge was irradiated with a dye laser at 577 nm and 579 nm, thus exciting the atoms from the 61P1 level to 63D level, which decays to the 63P levels. By measuring the time dependence of the optogalvanic and fluore-sence signals, the effective lifetime and the ambipolar diffusion coefficients were obtained. The theoretical explanation for the experiments is presented.

Published: November 2020

Crystal structures and magnetic properties of R13Fe74Si13 (R = Ce, Pr, Nd, Gd, Tb, Dy, Ho, Er, Y) alloys are investigated in this paper. The results show that R13Fe74Si13 alloys have pseudobinary intermetallic compound R2(Fe0.85Si0.15)17 as the main phase instead of forming a ternary compound of the type R2Fe14B. The Si atoms probably substitute for Fe atoms in R2Fe17 (9d site in Th2Zn17 or 6g site in Th2Ni17). Curie temperatures of R13Fe74Si13 alloys are comparably higher than that of R2Fe17. Saturation magnetization and magnetic anisotropy at room temperature were measured. Based on the results of extracting sample measurement at low temperatures the variation of the magnetization of R13Fe74 Si13 with temperature was discussed.
