Authors: Sharipov Rashid , Tyulyubayeva Dinara , Shavdinova Madina , Kudrevich Olga , Yerzhanov Syrymgali
Published: November 2020

The article touches upon the problem of energy saving and increasing energy efficiency in the construction sector, which consumes a significant share of the country's energy resources. The issues of rational use of energy resources with the aspects of energy saving, energy efficiency and, correspondingly, environmental problems are becoming increasingly important, and their solution has become a strategic task for Kazakhstan. In order to give momentum to energy saving measures carried out in Kazakhstan, a number of laws, bylaws and programs related to the rational use of energy resources and energy efficiency have been adopted. To solve this problem, it is planned to carry out targeted measures to eliminate existing political, legislative, technical and information barriers. A regulatory technical base is being developed based on the most recent advances of construction science.
FERNÁNDEZ RIVA, G. y MILLET, V. Hartmann von Aue: Der arme Heinrich. Textgeschichtliche elektronische Ausgabe. Universitätsbibliothek, Heidelberg, 2018
Authors: Pérez Ben Lorena
Published: November 2020

El poema narrativo de finales del siglo xii Der arme Heinrich, atribuído a Hartmann von Aue, se conserva en su totalidad en tres manuscritos y de forma parcial en varios pequeños fragmentos. En estos testimonios, si bien es cierto que la historia contada es en esencia la misma, se pueden apreciar importantes variantes así como transposiciones de versos, añadidos y eliminaciones que afectan a su comprensión y que a menudo pasan desapercibidas en los libros tradicionales. La edición electrónica Der arme Heinrich digital[1] pretende sacar provecho de las posibilidades que ofrece la tecnología para mostrar de una forma precisa la pluralidad y diversidad textual y facilitar su percepción. En esta reseña se describirá y estudiará lo que esta nueva herramienta pone a nuestro alcance.[1] https://doi.org/10.11588/edition.ahd
Voluntad y deseo en la filosofía moderna: un acercamiento computacional
Authors: Cebral Loureda Manuel
Published: November 2020

El artículo aborda el análisis computacional de varios textos clave de la modernidad filosófica, especialmente autores que tratan la voluntad y el deseo: Spinoza, Hegel, Schopenhauer y Nietzsche. A través de un estudio comparativo de medi-das de frecuencia de términos, redes de relaciones entre palabras, modelado de tópicos y análisis de sentimientos, se visualizan afinidades y tensiones entre estos textos, explicitando la importancia que en ellos tienen los conceptos menos vinculados a la razón y al conocimiento. Al mismo tiempo, el artículo reflexiona sobre la pertinencia de los métodos computacionales y cómo pueden servir positivamente para la investigación filosófica.
Bibliotecas de investigación y Humanidades Digitales en España. Una relación en construcción
Authors: Morales-del-Castillo José Manuel , Tamayo Ramírez Rosa María , Peis Redondo Eduardo
Published: November 2020

Las Humanidades Digitales definen un marco donde la tecnología es un elemento indispensable para la investigación en Humanidades y Ciencias Sociales, y donde las bibliotecas académicas pueden desempeñar un papel esencial. Este trabajo se propone detectar y analizar cómo se está desarrollando ese papel de colaboración en España en este momento cuando en otros países ya es algo habitual. Partiendo de una revisión bibliográfica que contextualiza la cuestión, se muestran los resultados de una encuesta realizada a bibliotecas académicas en universidades donde existen proyectos de Humanidades Digitales, y que ha sido la herramienta metodológica de este análisis. Los resultados arrojan que mayoritariamente esa colaboración existe, pero queda diluida entre otros servicios de apoyo a la investigación de las bibliotecas. Contar con bibliotecarios integrados (embedded librarians) (Shumaker y Talley, 2009), de amplias capacidades para la gestión y análisis de datos, entre otras propuestas posibles, puede enriquecer este tipo de proyectos.
What about fertility staff emotions? An explorative analysis of healthcare professionals’ subjective perspective
Authors: Fedele Fabiola , Caputo Andrea , Cordella Barbara , Muzii Ludovico , Pietrangeli Daniela , Aragona Cesare , Langher Viviana
Published: November 2020

Infertility-related psychological research is traditionally oriented to analyze the wellbeing of couples undergoing Assisted Reproductive Technologies (ART), than to study the job-related effects on the healthcare fertility staff. This piece of research aims at understanding the subjective perspective of the fertility professionals and contribute to identify their emotional dynamics in their work environment. An in-depth explorative research study was conducted on 12 healthcare professionals of an Italian ART hospital clinic. Structured interviews with open-ended questions were administered to explore their deep feelings about their professional experience. Emotional text analysis was then conducted to analyze the textual corpus of their narratives to grasp their affective symbolizations. Statistical multidimensional techniques were used to detect some thematic domains (cluster analysis) and latent factors organizing the contraposition between them (multiple correspondence analysis). Five thematic domains were detected which refer to different emotional dimensions, as follows: performance anxiety (Cluster 1), ambivalence between omnipotence and powerlessness (Cluster 2), care burden (Cluster 3), feeling of duty (Cluster 4), and sense of interdependence (Cluster 5). Then, four latent factors were identified dealing with the laborious attempt to remedy, the realistic sense of limitation, the incumbent feeling of pressure and the restorative sense of justice, respectively. The results are discussed based on the existing literature and some useful recommendations for staff education, training and clinical supervision are provided accordingly.

Value creation in category management relationships in the UK grocery market
Authors:   , Benson Michael Christopher
Published: November 2020

This thesis explores the nature of value, and value co-creation within the context of collaborative category management relationships in the UK grocery sector. Category management is the process which involves a collaboration between food manufacturers (suppliers) and retailers to manage the needs of shoppers. Research into category management is very timely as the retailing industry is currently facing one of its greatest challenges. Shoppers are becoming more demanding and expect better value from their purchases. The research reveals that shoppers are switching from branded to private label products following on from the recent success of Discounters. This has created opportunities for all category suppliers including private label and smaller niche suppliers, if they produce retailer specific innovative and creative ideas. It was also found that the role of the category captain was abandoned five years ago, despite being the focus of the category management literature even today. The role now known as ‘preferred supplier’ is available to any category supplier and is no longer the exclusive right of the largest branded supplier. The current research study has involved UK based food industry supplier category managers and retail buyers, to understand if category management collaborations created value. Following a phenomenological approach using long qualitative interviews, the findings were controversial in that both the suppliers and retailers were not completely satisfied with the category management relationship, and that value was not always created. This finding contradicts existing research, and indeed the rhetoric that normally purveysin practice. The researcher anticipatesthat the thesis will alert practitioners to the underlying issues that exist and encourage them to find ways of working closer together, without fear of displeasing the other partner. It will no doubt spark reformist debates between suppliers and retailers, as well as update the category management literature. The research findings move the category management conversation forward from an objective to a subjective explanation of value creation. Finally, it introduces the importance of Service-Dominant Logic S-DL in creating value through the lens of the five axioms of S-DL. It also adds further insight from a supplier’s perspective based on confidential testaments of practitioners on the front-line.
Felicity conditions of a theory of expert leadership in professional football
Authors:   , Mighten Eddie
Published: November 2020

This thesis is a critical investigation of a theory of expert leadership (hereafter TEL) and has the central aim of theory development. In proposing a TEL, Goodall (2012) argues that those at the top of organisations should be among the best experts in their industry, as opposed to general, professional managers. Empirical support for the TEL and its effects are reported in a small number of studies that show positive correlations between expert leadership and organisational performance. Moreover, expert leaders are thought to gain credibility and respect and are better able to understand motivations and values of followers having been one of them. Whilst these findings are interesting and imply something important in terms of what we might look for when choosing leaders, they raise conceptual and methodological concerns that were the starting point for this study. My approach draws on Gadamer’s (1989) conceptualisation of hermeneutics and Josselson’s (2011b) narrative approach in what I described as hermeneutic storytelling to account for the lived experiences of managers in the backdrop of men’s professional football, on the assumption that stories about our lives are representations of reality. To explore this phenomenon, I borrow from J. L. Austin's (1962) work, How to Do Things With Words, and the idea of felicity conditions, as a theoretical lens to understand expert leadership influence. Felicity conditions refer to criteria that must be in place and satisfied for performative acts to achieve their purpose. As a theoretical contribution to knowledge I found first that, for expert leadership influence to be felicitous, football managers need to meet, in the requisite way, conditions of; authority and be authorised beyond the position they hold; which is granted by virtue of authenticity, in the way they operate in relation to others; and sincerity, with thoughts, intentions and motivations that embodied the virtue. This is mediated by interplay of thoughts, beliefs and expectations of people who interact with football managers and also what is rooted in historically affected cultures and traditions. Second, there is a dark side to this leadership that undeniably exists and in any study involving people who have great authority and hold powerful positions this reality needs to be truthfully told. Third, as a practical contribution my thesis proposes the Human Resources (HR) profession, and recruitment in general, moves away from traditional competency and behavioural practice, to selecting leaders on a values-based process, that assesses the fit of human values and the cultural of an organisation. My thesis allows the reader to reimagine expert leadership and proposes the need to examine what is human about the phenomenon in question. I conclude, the TEL is a paradoxical mix of perceptions of leadership qualities, human conditions and performativity in context.
The application of cognitive poetics to the primary school reading experience
Authors:   , Devoy Chantelle
Published: November 2020

This thesis examines the reading experiences of Key Stage 2 students, through a cognitive poetic lens. Cognitive poetics is a strand of stylistics that helps us to understand the reading process. This is particularly useful given the current state of English education, where scores, tests, de-contextualised grammar and linguistic analysis dominates the field. This thesis champions authentic reading as a way of challenging these distorted priorities and seeks to reflect and engage with an individual’s own interpretation and reading of the text. Legitimising individual students’ responses, with the use of cognitive poetics, has allowed me to unearth the elements of English and reading I believe are particularly salient. The thesis details the findings of my ethnographic investigation of a school advocating for reading for pleasure, authenticity and personal response. It draws on two cognitive poetic frameworks (schema theory and text-world theory) to examine the potential of individual student textual interpretation, the aspects of their background knowledge that had contributed to these interpretations, and the process of their eventual understanding. This research is especially valuable in highlighting the potential of cognitive poetics as a ‘lens’ through which to view reading practices in schools. The relevance of this research is undeniable when situated alongside current debates in the field of English - including arguments surrounding a ‘best’ pedagogical practice, the effects, value and importance of reading, and the current content and culture of English in the classroom.
L’histoire de la pêche sportive au Québec
Authors: Martin Paul-Louis
Published: November 2020

En prenant possession du Canada en 1759, les Britanniques introduisent la pêche à la mouche, un loisir jusque-là inconnu dans la vallée du Saint-Laurent. Les militaires, en poste à Québec, fréquentent les rivières à saumons les plus proches avant d’explorer les cours d’eau fabuleux de la Côte-Nord puis de la Baie des Chaleurs. L’industrialisation et l’exploitation forestière intensive menaçant la santé des cours d’eau et la survie des poissons, les gouvernements du Canada et du Québec adoptent diverses mesures législatives en vue de sauvegarder le paradis de la pêche à la ligne qu’est devenu le pays. Ainsi, en 1885, voit le jour le système très élitiste des clubs privés de chasse et pêche, qui perdurera jusqu’à son abolition en 1978. Désormais administré de façon adéquate et responsable, le territoire comprend des réserves et des parcs nationaux ainsi que des Zones d’exploitation contrôlée gérées par des résidents locaux.
Les intrigues carnavalesques, « mi-carêmes » ou « mascarades ». Étude croisée en Europe et Amérique francophones
Authors: Lempereur Françoise
Published: November 2020

En Europe comme en Amérique francophones, les intrigues carnavalesques ne perdurent que dans quelques villages ou petites villes qui ont gardé une population assez homogène : des masqués pénètrent dans les maisons dont ils connaissent les occupants et rappellent, sur un mode humoristique ou satirique, des anecdotes ou des situations personnelles relatives à leurs « hôtes ». Ils déguisent leur voix afin de tenir le plus longtemps possible avant d’être reconnus. Agacées, les personnes visées tentent, dans la bonne humeur, de les démasquer en offrant à boire. L’auteure a dépouillé la littérature sur le sujet et a personnellement observé la pratique, qu’elle décrit et analyse en alliant méthodologie ethnographique et réflexion socio-politique.
Le travesti de saint Nicolas, une tradition familiale
Authors: Genest Bernard
Published: November 2020

Personnage légendaire, saint Nicolas est issu du culte d’un saint originaire de l’Asie mineure qui se répandit à travers l’Europe dès le xe siècle, avant d’atteindre l’Amérique au xviie siècle. À New York, la figure du saint se métamorphosa en Santa Claus au xixe siècle. Au Québec, saint Nicolas rivalisa un temps avec l’Enfant Jésus lors de la distribution des étrennes du jour de l’An. Jamais très populaire, il fut définitivement remplacé par le père Noël dans la deuxième moitié du xxe siècle. S’appuyant sur une enquête orale et sur ses propres souvenirs, l’auteur explique comment cette tradition, introduite dans la famille par son arrière-grand-père, s’est transmise d’une génération à l’autre jusque dans les années 1950.
Un corpus nommé désir : le laboratoire d’étonnement pour réintroduire l’affect dans la recherche
Authors: Collin-Vallée Tommy , Merri Maryvonne
Published: November 2020

Cette contribution présente les fondements d’un laboratoire d’étonnement comme moyen méthodologique de transformer un objet de déception en objet de désir pour le chercheur. Tout d’abord, les auteurs proposent une lecture spinoziste de leurs émotions causées par leur confrontation avec un matériau étranger au domaine de la psychologie, un docu-feuilleton sur le décrochage scolaire intitulé « Les persévérants » (Ferron et Baer, 2014). Ils considèrent l’étonnement comme un affect pour renouveler l’intérêt du chercheur pour son sujet de recherche. Ils en examinent ensuite les conditions d’émergence. Enfin, les conditions de mise en place d’un laboratoire d’étonnement sont illustrées par des exemples tirés de la littérature et des pratiques des auteurs.
L’évolution d’une posture de recherche : le soutien par l’analyse en mode écriture
Authors: Gremion François
Published: November 2020

Ce texte relate l’évolution de la posture de chercheur de l’auteur au cours de la réalisation de sa thèse de doctorat et son lien avec le choix d’une démarche d’analyse. Incidemment, ce récit comporte les dimensions d’une recherche autobiographique. Ce texte illustre comment, dans le cadre d’une thèse, l’auteur a mis en oeuvre un lent processus évolutif de sa posture de chercheur grâce au moyen d’une démarche d’analyse en mode écriture. Un retour à l’écriture manuscrite, considérée ici comme une ficelle d’analyste, a permis le déploiement de la pensée nécessaire à la conceptualisation et à la transformation de son « soi » professionnel et personnel au travers d’une méthode d’analyse se déroulant en cinq temps, de la transcription à la rédaction finale du rapport.
À la recherche du monde vécu
Authors: Veillette Sylviane , Merri Maryvonne
Published: November 2020

Cet article apporte une vision critique de la transposition didactique de l’approche dominante de la psychologie, étendue aujourd’hui à la psychologie de l’éducation. D’abord, nous présentons les principes scientifiques retenus dans la formation en psychologie. Ces principes concernent la notion de participant, les objets de recherche privilégiés et l’activité du chercheur. Nous montrons, à la suite d’Habermas (1987), que cette psychologie participe à une « colonisation du monde vécu » et à un rétrécissement historico-culturel de celui-ci. Nous proposons enfin une alternative épistémologique et méthodologique permettant une relecture de ces trois principes dans une perspective historico-culturelle.
Del este de Europa al sur de América: migraciones soviéticas y postsoviéticas a la ciudad de Bucaramanga, Santander
Authors: Umaña Cifuentes Mayra Alejandra
Published: November 2020

El objetivo principal de esta obra es reconstruir los procesos migratorios que llevaron a los migrantes de la ex Unión de Repúblicas Socialistas Soviéticas, a residir en Bucaramanga (Colombia). Así mismo, se indaga sobre la falsa creencia de que en Colombia no existe la inmigración y el vacío en la producción académica frente a este tema, que suele centrarse en las personas que dejan el país y no en quienes llegan. Por otro lado, se indaga sobre el hecho de que la literatura sobre el tema obedece más a investigaciones de tipo histórico. Metodológicamente, este estudio se sustentó en el uso de historias de curso de vida basados en los supuestos de Howard Becker, donde el uso de historias de vida permite aproximarse a cuestiones subjetivas de los investigados, sus experiencias, sus motivaciones y la interpretación que estos tienen de su realidad. Cuestiones que sólo pueden ser entendidas desde el punto de vista de quien vivió una experiencia y que de no ser así se podría incurrir en suposiciones y conjeturas.

A series of magnetic modes were observed in LPE YIG films magnetized in plane. These magnetic modes were excited by means of magnetostatic wave excitation and show characterisitics of equal spacing and slower attenuation than normal standing spin waves. Considering that the precession is elliptical and supposing there are inhomogenuity of magnetization in the film, we deduced relation between mode spacing and magnetic parameters of YIG. Comparing with experiments, an inhomogenuity of 2.6—5.8% were deduced for our LPE YIG films.

Published: November 2020

The EXAFS of amorphous semiconductor a-As2Se3, a-AsSe, a-As0.05 Se0.95 and a-As2Se3) after annealing at different temperatures lower than Tg are measured by 12 kW rotating anode X-ray diffraction equipment. Analyses of the determined radial structural functions shows that although the short range structure of a-As2Se3 is very similar to that for crystalline As2Se3, some changes take place in its radial structural function after annealing. The structural relaxation in a-As2Se3, quenched from melt, has also been observed. The short range structures for different components of As in binary As-Se system seem to be different.

The total widths of two excited states at 9603.9 keV, 10321.0 keV and of a doublet at 9864.6, 9868.8 keV in 40Ca have been measured with resonance γ-ray absorption. The gamma radiations from 39K (p, γ) reaction at EP=1307.2 keV, 2042.8 keV and 1595.0 keV have been selected to excite the corresponding levels in 40Ca. The accurate results for the widths of the 9603.9 keV and 10321.0 keV states are obtained for the first time, they are 188±47eV and 91±15eV, respectively. For the 9864.6 and 9868.8 keV states, they are 100±24eV and 899±214 eV. Because the 9864.6 and 9868.8 keV states are close-lying doublet, the resonance γ-ray absorption techniqque was used in a special style: there will be two groups of gamma rays to be used to excite the same two levels, so the cross excitation occurs. We extended the corresponding exper mental analysis. In addition, (p,γ) yield measurenents have been made to extract the level widths of the 9603.9 keV, 10321.0 keV states. And the results are in agreement with the values deduced from resonance γ-ray absorption. The (p, γ) resonance strengths and isospins of the 9603.9 keV and 10321.0 keV states in 40Ca have also been discussed.

A STUDY ABOUT THE EXISTENCE OF DIHYDRIDE PHASE ON HYDROGEN CHEMISORBED Si(111) SURFACE
Authors: Hu Ji-huang  , Liu Guo-hui  , Wang Xun  ,   复旦大学表面物理实验室
Published: November 2020

The chemisorption states of atomic hydrogen on Si (111) surface have been studied by means of thermal desorption spectra. Two desorption peaks β1 and β2 were observed. At low hydrogen exposure only peak β1 could be seen. The peak β2 appeared at higher hydrogen exposure and could not exist if the sample was exposed to hydrogen at a temperature higher than 400℃ or was annealed above 380℃ after hydrogen exposure. The saturated coverage of β2 was less than that of β1 by a factor of 2. The peak β1 is related to the top site adsorption of H on surface Si atoms as reported by previous works. The relatively high activation energy of desorption for β2 implies that its adsorption state is likely to be a chemical, bonding state instead of a non-bonding state as postulated by Schulze and Hender. All the above desorption behaviors of β1 and β2 are quite similar to those of monohydride phase and dihydride phase of H on Si (100) surface. Therefore, it is reasonable to deduce that the β1 and β2 states correspond to the monohydride and dihydride phase on Si (111) respectively. A triangle dimer stacking fault model of Si (111) (7×7) reconstruction proposed by McRae could be used to give an exp-laination of forming surface silicon dimer bond and thus the dihydride phase on clean Si (111) surface.

The electronic transport processes in metallic superlattices are studied by solving Boltzmann's equation with inclusion of a temperature gradient as well as an external magnetic field and by adopting the treatment of interface scattering processes in our revious interpretation of electric conduction characteristics. Variations with modulation wavelength of the thermoelectric power, the electronic thermal conductivity, the Thomson and Hall coefficients are derived for Nb/Ti superlattices. Further experimental investigations on the transport properties of metallic superlattices are expected to help the understanding of the electronic processes in such artificial materials.

The structure of the metallic glass Ni64B36 is simulated by a computer model which consists of two different size spheres. We calculate the partial radial distribution functions, the angular distribution functions and the homogeneity of the model, and discuss the chemical short-range order of the structure. All the results show that in the transiion metal-metalloid glasses, the relative distribution of the metalloid atoms is an important characteristic of the chemical short-range order, this can be characterized by the site rc of the first split peak of the metalloid-metalloid distribution function.

Published: November 2020

The structural defects, quenching defects and electron-irradiation defects in the in-termetallic compounds NiAl have been studies with the positron annihilation technique. The recovery behaviour of quenching defects and irradiation defects have been inversti-gated. Two distinct recovery stages have been, found, one at about 280℃ and the other at about 500℃. The experimental results show that the low-temperature stage is due to the annealing out of the divacancies and the high-temperature stage is due to the annealing out of the vacancies; and the density of the conduction electrons at the vacancies and the lattice interstitial sites are nearly equal to each other, but the momentum of the conduction electrons at the vacancies is lower than that at the latties interstitialsites in NiAl.
EFFECTS OF BONDED HYDROGEN ON THE PHOTOLUMINESCENCE PROPERTIES OF GD a-Si:H THIN FILMS
Authors: MA HONG-LEI  , ZHOU YU-FANG  , LI DUN-YIN  ,   山东大学物理系
Published: November 2020

The photoluminescence spectra and optical absorption spectra were measured for GD a-Si :H films prepared at different substrate temperatures. It is found that increasing bonded hydrogen centent results in a systematic increase of the photoluminescence peak intensity, peak energy, linewidth, Stokes shift, and thermal quenching. From the experimental results we infer that: (1) The bonded hydrogen may generate radiative recombination centers as well as may remove non-radiative recombination centers; (2) The increase of the bonded hydrogen centent results in increase of the elec-tron-phonon interaction and a slight reduction in the band tail width.

Published: November 2020

The infrared divergence response theory is applied to the two-level System model of structural defects in glasses, and the twopeak structure of the ultrasonic absorption is explained by this theory. It is reasoned out that the small low-temperature peak depends more strongly on frequency than that of the high-temperature peak. On the basis of indroducing the effective potential, a good agreement with experimental data for ultrasonic aibsorption in SiO2 is attained over the whole temperature range.

In the sub-micron channels of semiconductor surface, it has been found that the conductivity has oscillation structure with gate voltage. We calculate the local density of states for the narrow channel by using Green function method and see that the density of states shows a series of sharp peaks, which can be used to explain qualitatively the conductivity oscillation.

Effect of W addition on Curie temperature TC, thermal stability and temperture coefficient of resistivity of amorphous Fe-B alloys are studied. The decrease of TC and increase of thermal stability in amorphous (Fe1-xWx)84.5B15.5 alloys with increasing W content are discussed. The change of the resistivity with increasing temperature can be interpreted in terms of the phonon and the local spin fluctuation scattering.

Published: November 2020

In this article, a new way is explored, which uses the method of image reconstruction from the projection based on the theory of random transformation, to determine simultaneously the magnetic configuration and 2-D distribution of physical quantities of non-circular cross-section plasma from the diagonostic results. Assuming that the distributions of the physical quantities only depends on the magnetic surface function and all the surfaces are similarly concentric, we have proposed three methods of treatment. For D-shaped plasma, the analytical treatment and numerical simulation have been discussed in detail. An example of determination of magnetic configuration and electron temperature and density from soft X-ray and microwave interference measurements has been demonstrated.

In this paper, the relationship between composition and crystallization temperature of Fe-base amorphous alloys are investigated systematically. Among 95 Fe-base amorphous alloys, the crystallization temperatures of about 85% of them are in the range of 700-825 K, Tcr/Tm≈1/2 (0.42-0.62), and conform to Sakka's principle The crystallization temperature of Fe1-x Bx-ySiy is greater than that of Fe1-xBx and the later greater than that of Fe1-xBx-yPy in turn. Those mentioned above are discussed with reference to the composition, phase diagrams, machanism of the crystallization, diffusion and the relationship between the crystallization temperature and the average electronic concentration (e/a).

Published: November 2020

The 〈0001〉axial channeling parameters, axial half-angle ψ1/2 and minimum yield xmin, of α-LiIO3 crystal have been measured by collimated MeV proton beam at different beam energies. Under the action of an electrostatic field along the c-direction of the crystal, the increase of channeling-backscattering yield from the surface I atoms, proportional to the duration of electrostatic field action, has been observed. The time-dependence of the amount of the random surface I atoms has been calculated quantitatively for different durations of electrostatic field action. The increase of the α-particle yield from proton induced 7Li(P,a)4He reaction-channeling with the duration of electrostatic field action has been observed as well.

Published: November 2020

The study on magnetic properties of RF sputtered iron oxide thin films was carried out systematically. More specifically, the temperature dependence (77-500 K) of the coercivity and the variation of coercivity with different iron oxide phases such as the as-sputtered Fe3O4, partially transformed Fe3O4/(γ-Fe2O3), and γ-Fe2O3, were investigated. Comparing the theoretical analyses with the experimental results, the contributions to the coercivity from shape anisotropy, magnetocrystalline anisotropy, and stress-induced magnetic anisotropy were obtained separately. And the first-order crystalline anisotropy constant K1 vs. temperature for Fe3O4 and γ-Fe2O3 films was derived from Ms(T) and Hc(T) over the temperature range of 100-500 K.

The ionic conductivities of some PECH-and PECH-PEO-alkaline salt complexes have been determined. The effect of some factors such as polar group concentration, cation size and anion size as well as procedure of thin film preparation on conductivity of polymer ionic conductor has been studied. For lithium salt complex the polar group reduces the conductivity, while for sodium salt complex the polar group enhances the conductivity. This phenomenon was explained by a model involving the existence of two kinds of potential well in the polymers. It has been found that the cation size has strong influence on conductivity. For both small Li+ and large K+ , the conductivity is low but for mediun size Na+, the conductivity is high. An ion transport picture in amorphous PECH has been proposed to illustrate this behaviour. In addition, it was shown that the larger the anion size is, the lower the conductivity will be. Finally, the re-sults suggested that the procedure of thin film preparation influenced the film conductivity.

Using the radioactive gamma ray source 141Ce (Er = 145 keV) and Ge(Li) detector (FWHM = 2.21keV at 1.33 MeV), we have measured the cross sectipn of photon coherent scattering from Al, Fe, Cu and Pb over the range of momentum transfer x=1.2-5.0 ?-1. The theory of form-factor approximation resulting from relativistic Hartree-Fock (RHF) atomic model is found to be adequate in explaining the experimental results.
