Similitude between the Earth’s nucleus and the Earth–Moon barycenter
Get PDFBeing interested in problems which regard the Earth’s rotation around its axis, we made some attempts to find the limits of the Earth–Moon barycenter inside the Earth. We found that the Earth–Moon barycenter surrounds the Earth nucleus. We also noticed that when the angle between the Earth equator and the Moon’s orbit reaches its minimum value at 18.3°, the barycenter spiral with around 27 whirls surround only the inner core
Design of Uniform and Nonuniform Circular Arrays Comparison with FFA and RLS
Get PDFMultiple antennas can be arranged in various geometrical configurations to form antenna array with high directive radiation pattern. Linear antennas are limited in their steering capability. The circular arrays ar more popular in recent years over other array geometries because they have the capability to perform the scan in all the directions and considerable change in the beam pattern which provide 3600 total coverage. Circular arrays are less sensitive to mutual coupling as compared to linear and rectangular arrays since they do not have edge elements. They can be used for beam forming in the azimuth plane for example at the base stations of the mobile radio communication systems as the components for signal processing. FFA design method of circular apertures for narrow beam width and low side lobes has been reported by Taylor. It includes the development of continuous circular aperture distributions, which contain only two independent parameters, A & , where A is related to the design of side lobe level and is a number controlling the degree of uniformity of the side lobes
The embodied grounding of focal parts in English wh-dialogues with negative answers
Get PDFNegative answers are common types of responsive expressions to English wh-questions. From the theoretical perspective of Embodied-Cognitive Linguistics (Wang, 2014) and the dialogic view on meaning construction, this study takes English wh-dialogues with negative answers as the research object and regards such dialogues as a special group of dialogic constructions in conversation. This paper gives an account of the embodied properties of the semantic grounding process of dialogic focuses in such constructions, in terms of the types of the semantic grounding and the categories of semantic consistency of focal parts of wh-questions with those of negative answers, with the ultimate goal to decipher the cognitive mechanism by which wh-dialogues with negative answers are produced and construed in linguistic communication.
Catalytic performance of Ce1-xLnxOy of nanocrystalline Ln (III-IV)-substituted ceria
Get PDFThe activity of several lanthanide promoted Ceria in CO oxidation was studied. Samples were obtained by a high yield and sustainable method by urea thermal decomposition. Precursors basic carbonates, Ce1-xLnx(OH)CO3, being Ln = La (III), Sm(III), Gd(III), Pr(III) were prepared in the range of compositions 0 to 30 at.%. These precursors were annealed to moderate temperature obtain Ln-Ce mixed oxides, at 450ºC. These exhibit large surface areas up to 120 m2/g. Their catalytic performance revealed good activity towards CO oxidation (COOX) for all samples. However, a different behavior may be observed for Ln content higher than 20 at.%. By the reactor operation in differential conditions, the activation energy for COOX were obtained for all samples. The rise of activation energy as a function of Ln(III-IV) content is analyzed in the frame of phase stability and surface segregation
Revisit euphemisms from the perspective of intentionality
Get PDFThis paper studies the role of intentionality in the process of generating euphemisms. Intentionality, as the key to human consciousness activities, is not only the starting point of the language user’s consciousness activity related to euphemism generation, but also functions through the whole generating process. Its functions can be specified as triggering, orientation, and selection. Collective intentionality restricts individual intentionality and has the function of identifying and integrating individual intentionality. Under the effect of collective intentionality and social environment, the euphemisms are renewed with the time and bear features unique to a particular group.
Prepare Foam with Injection Molding Method in Acrylonitrile-Butadiene-Styrene (ABS) Matrix Using Chemical Foam Agent
Get PDFIn this study, it is aimed to decrease the weight of the material by using polymer foam materials with lower density instead of commercial polymers which have wide usage area. For this purpose, polymer foam was produced by using an acrylonitrile butadiene styrene (ABS) matrix and an endothermic chemical foam agent using injection molding method. The foam cell morphology, shell layer thickness and mechanical properties of the final part were investigated taking into consideration the weight-changing ratios of the foam agent content (1-1,5-2-2,5-3%)
Japanese Initiative for Education in Pharmaceutical Medicine and Clinical Research Training
Get PDFDevelopment of new medicines has become increasingly difficult with less possibility of success in seeds-finding and ever rising operational costs. Failure to comply with ethical standards for human research protection also erodes social trust in clinical development. In order to develop competence of professionals in medicines development such as clinical investigators and drug development scientists, a variety of educational courses and training programs have been developed and executed worldwide. As Japan is no exception and shares the same concerns, significant governmental and non-governmental efforts have been made to invest in the development of academic educational courses and adherence to international standards. This article introduces examples of the adoption of technologies to realize a user-friendly and sustainable learning management as well as an adaptation of syllabuses and core curricula to meet international standards in the era of global medicines development
Investigation into the research on doctoral writing: A synthesis of recent research (2010-2019)
Get PDFDoctoral writing has been concerned by linguistic scholars and the practitioners of English for academic purposes. This review explores the literature on doctoral writing which got published in peer-reviewed international journals of English between 2010 and 2019 to examine three questions: (1) From which perspectives do the recent researches adopt when examining doctoral writing of the ESOL students? (2) What methodology do the authors apply to research doctoral writing? (3) What kind of text or resource was analyzed by the authors? The goal of the review is to provide the pedagogical suggestions to the future teaching of doctoral writing and viable supports for the writing practice of doctoral students by a comprehensive analysis of the current research. After the overall search on Scopus, 210 titles and abstracts have been searched out through a combination of search terms. The inclusion and exclusion criteria have been used to identify the qualified articles for this study and disqualify the possibly irrelevant articles from the included. Ultimately, 82 articles have been confirmed to be further reviewed for the solution of research questions. This review indicates the relationship between doctoral writing and pedagogical and social context is complex, and thus necessary supports from inside and outside of doctoral community need to be given to improve the writing competence of doctoral students
Translation from EFL textbook to classroom: Pedagogy, semiosis and strategy
Get PDFThe modern semiotic world has undergone dramatic changes. Due to the development of technology, a wide range of media and mode are now available to sign makers, facilitating as well as requiring translations within and across semiotic systems. This research takes a social semiotic multimodal approach to study translation practices in educational situations in China. It explores how meaning is translated from EFL textbook to classroom teaching in Chinese universities, from the aspects of pedagogy, semiosis and effects. Focusing on translation, this article analyzes how pedagogy is redesigned in terms of situated practice, overt instruction, critical framing, and transformed practice. Based on the analysis of semiotic resources available in textbook and classrooms, this article discusses the functional loads of modes, patterns of mode combinations, translation categories, and semiotic strategies for realizing multiliteracies pedagogy. Finally, the effects of translation are explored in terms of pedagogy, sentient perception, cognitive process, physical features, and dissemination quality
Research on motion-emotion metaphor and its social cognitive mechanism—A case study of Chinese Mandarin, Yi language and English
Get PDFChinese motion-emotion metaphor and its social cognitive mechanism are explored, for the first time, with a comparison between Mandarin Chinese, the Yi language and English. The interaction between motions and emotions is the key to do the research from the perspective of cognitive functionalism. Cognitive functionalism argues that language reflects people’s consciousness, and the cognitive aspect of language interacts with the communicative function of language very well. According to this argument, motion-emotion metaphor, as a popular language phenomenon, can testify to such interactions. The comparative analysis of motion-emotion metaphors, from the perspective of cognitive functionalism, in this paper has proved to take the following aspects into consideration: the subjects’ experiences of physical motions and their effects on objects; the universality and the specificity of such experience; the emotions’ observable traits and their related motions; the common knowledge and normal beliefs among the motions’ subjects and their surrounding contexts
