For hundreds of years, it has grown out of nothing to brilliant performance by several generations of Chinese geologists committing their hearts and minds with the spirit of exert and strive without stop to promote the process of China's industrialization and to produce the significant impact on serving the society. The study of Chinese geosciences history reflects objectively and historically the history of geosciences in China, which has recorded, analyzed and evaluated the dynamic process sitting in the background and clue of the history of Chinese geosciences development. The study of the history of geological science has roughly experienced two stages in China. The first stage is the study of individual researchers. It spanned approximately 70 years from the early 20th century to the end of the 1970s. The research contents were mainly based on the evolution of geological organizations, the development and utilization of individual mineral species, the history of deposit discovery and the research of geological characters. The main representatives are Zhang Hongzhao, Ding Wenjiang, Weng Wenhao and Li Siguang, Ye Liangfu, Huang Jiqing, Yang Zhongjian, Xie Jiarong, Gao Zhenxi, Wang Bingzhang and etc. The most prominent feature of this period is the accumulation of a very valuable document for the study of the history of China's geological history and lays a foundation for the exchange of geological science between China and foreign countries. The second stage is organized group study. It took around 60 years from the 1920s to 1980s. It includes the history of Chinese geology, the history of geological organizations, the history of geological disciplines, the history of geological education, the history of geological philosophy, the history of Chinese and foreign geological science communication, the history of geologists and etc. The most chief feature of this stage is the birth of academic research institute--the establishment of the Commission on the History of Geology of the Geological Society of China.展开更多

There are analyzed the chosen “great” and “grand” problems of phys-ics (including the comprehension of quantum mechanics, with a recently elaborated new chapter, connected with time as a quantum obs- ervable and time analysis of quantum processes) and also of natural sciences as a whole. The particular attention is paid to the interpretation questions and slightly to the aspects, inevitably connected with the world- views of the res- earchers (which do often constitute a part of the interpretation questions).展开更多

Incorporating fluids saturation logs during the history matching phase unlocks the possibility to adjust or select models that better represent the near wellbore waterfront movement, which is particularly important for uncertainty mitigation during future well interference assessments in water driven reservoirs. For the purposes of this study, a semi-synthetic open-source reservoir model was used as base case to evaluate the proposed methodology. The reservoir model represents a water driven, highly heterogenous sandstone reservoir from Namorado field in Brazil. To effectively compare the proposed methodology against the conventional methods, a commercial reservoir simulator was used in combination with a state-of-the-art benchmarking workflow based on the Big LoopTMapproach. A well-known group of binary metrics were evaluated to be used as the objective function, and the Matthew correlation coefficient(MCC) has been proved to offer the best results when using binary data from water saturation logs. History matching results obtained with the proposed methodology allowed the selection of a more reliable group of reservoir models,especially for cases with high heterogeneity. The methodology also offers additional information and understanding of sweep behaviour behind the well casing at specific production zones, thus revealing full model potential to define new wells and reservoir development opportunities.展开更多

Here laboratory animals such as rats, frogs and rabbits were used in medical education to demonstrate physiological principles in the early 1950 s. The establishment of the first animal house in 1969 at UCFM better facilitated the use of laboratory animals in medical education and research. By 2006, lack of ethical guide lines was an issue and a set of ethical guidelines was developed and published in 2009, which today are followed by researchers and reviewers in many universities and research institutions in the country. With this development, there was a need for an organized system of education for the LAS discipline. This was fulfilled by conducting the first certificate course on LAS in the Asian region in 2011 in collaboration with the Utrecht University,Netherlands. The Sri Lanka Association for LAS has continued LAS education since its establishment in 2012 at UCFM by conducting workshops and short courses.展开更多

Music education is presented in the relationship of the two main areas: science and education. There is evidence of a gradual expansion and changes in the content and methods of the science of music. The 21st century rapidly and dynamically entered in our lives in terms of the development of information communication, technological progress and unprecedented rise of scientific thought. Social upheavals of this period of history, a powerful wave of liberation movements have caused an unprecedented intensification of national creative forces committed to the development, expansion of contacts, attached to the other cultures. To date, the science of music has evolved so much on what grew out of it and separated into clearly separate spheres with their problems, trends, directions: music theory, music history, ethnomusicology, musical philosophy, and also music source studying. And it should be noted that each of these areas has its embodiment in materialized form of faculties, departments in the conservatory. Development of new standards, new plans, programs, new courses is a related process of development of these sciences in general.展开更多

Over those years, the scholars in that field started to show a peculiar epistemological sensitivity. Spurred by the philosophical debate which was raised by positivism and particularly by Comte's and Spencer's studies, researchers wondered whether the most appropriate place for accounting was in the large field of social sciences. Hence, two different epistemological approaches arose with one succeeding the other in time. Initially, scholars accepted the idea that accounting somehow depended on its related sciences, which included economics. They deemed it convenient to use, also for their own purposes, principles drawn from contiguous doctrines that had already been scientifically recognized, such as economics. That was how Italian accounting happened to be, even though temporarily, in a position of "scientific subjection" with respect to the mentioned doctrines. At the second stage, due to the awareness of the specific subject and the method of investigation, as well as the purposes, Italian accounting claimed its own scientific autonomy, so scholars went back to the first phase and considered it necessary to develop internal principles and rules as a function of its peculiar needs. By doing so, scholars mapped out a route that would deeply mark the future of the discipline by making it fully independent on other fields of knowledge in a sort of emancipation process. The paper will not only describe the two theoretical positions which are summarized above, but will also adopt an interpretative approach to trace their possible causes and to grasp their effects on the development of the discipline, particularly with regards to the theories of value which is adopted by the Italian accounting over the analyzed period. In the authors' opinion, the attention paid by the most authoritative Italian accounting scholars to the epistemological theme of relationships between accounting and its similar sciences can be explained by at least two different causes: the influence which is exercised by the philosophical studies and the aspiration of accounting for scientific and academic recognition.展开更多

The history of written in the paper. Also history mention of Laue's experiment in Russia was presented. The system group of X-ray diffraction was created in 1919/1920 in Petrograd (A. Ioffe, State Physical Technical Institute) and Moscow. Themes of research results, scientific newness and scientific rate were presented. The organization, political and other reasons which retarded the active progress of the method in 1930 were described. Initial stage of progress of the method in Russia-USSR was studied by historian of science partly. The reasons of it are: closed of scientific community, political system of country, Cyrillic barrier, etc.. This paper acquaints western scientific community with non-famous Russian materials on theme.展开更多

Virtually all human activities that occur on planet Earth--including agriculture, energy and mineral resource exploration and extraction; environmental and public policy on natural resources management and protection; land use planning; infrastructure development; and ecological tourism--all depend on various aspects of geology and its sub-disciplines. Due to the importance of geology in the daily lives of human beings, it is imperative that all persons develop at least a basic understanding of the science. In this paper, the current efforts for promoting public understanding in geology will be examined, with offerings of alternatives and supplements to these efforts. Information from the science education sub-disciplines of HPS (history, philosophy and sociology) of science, and informal/free-choice learning will be woven into the framework of the geology-public understanding idea.展开更多

文摘This paper proposes a methodology for an alternative history matching process enhanced by the incorporation of a simplified binary interpretation of reservoir saturation logs(RST) as objective function. Incorporating fluids saturation logs during the history matching phase unlocks the possibility to adjust or select models that better represent the near wellbore waterfront movement, which is particularly important for uncertainty mitigation during future well interference assessments in water driven reservoirs. For the purposes of this study, a semi-synthetic open-source reservoir model was used as base case to evaluate the proposed methodology. The reservoir model represents a water driven, highly heterogenous sandstone reservoir from Namorado field in Brazil. To effectively compare the proposed methodology against the conventional methods, a commercial reservoir simulator was used in combination with a state-of-the-art benchmarking workflow based on the Big LoopTMapproach. A well-known group of binary metrics were evaluated to be used as the objective function, and the Matthew correlation coefficient(MCC) has been proved to offer the best results when using binary data from water saturation logs. History matching results obtained with the proposed methodology allowed the selection of a more reliable group of reservoir models,especially for cases with high heterogeneity. The methodology also offers additional information and understanding of sweep behaviour behind the well casing at specific production zones, thus revealing full model potential to define new wells and reservoir development opportunities.
文摘In a recently published article Sydney Brenner argued that the most relevant scientific revolution in biology at his time was the breakthrough of the role of "information" in biology.The fundamental concept that integrates this new biological "information" with matter and energy is the universal Turing machine and von Neumann's self-reproducing machines.In this article we demonstrate that in contrast to Turing/von Neumann machines living cells can really reproduce themselves.Additionally current knowledge on the roles of noncoding RNAs indicates a radical violation of the central dogma of molecular biology and opens the way to a new revolution in life sciences.

And it should be noted that each of these areas has its embodiment in materialized form of faculties, departments in the conservatory. Development of new standards, new plans, programs, new courses is a related process of development of these sciences in general.
文摘This paper takes into consideration the doctrinal positions that are taken by Italian accounting in the period between the 19th and the 20th century, and concerns the nature of relationships between accounting and its most similar sciences, particularly economics. Over those years, the scholars in that field started to show a peculiar epistemological sensitivity. Spurred by the philosophical debate which was raised by positivism and particularly by Comte's and Spencer's studies, researchers wondered whether the most appropriate place for accounting was in the large field of social sciences. Hence, two different epistemological approaches arose with one succeeding the other in time. Initially, scholars accepted the idea that accounting somehow depended on its related sciences, which included economics. They deemed it convenient to use, also for their own purposes, principles drawn from contiguous doctrines that had already been scientifically recognized, such as economics. That was how Italian accounting happened to be, even though temporarily, in a position of "scientific subjection" with respect to the mentioned doctrines. At the second stage, due to the awareness of the specific subject and the method of investigation, as well as the purposes, Italian accounting claimed its own scientific autonomy, so scholars went back to the first phase and considered it necessary to develop internal principles and rules as a function of its peculiar needs. By doing so, scholars mapped out a route that would deeply mark the future of the discipline by making it fully independent on other fields of knowledge in a sort of emancipation process. The paper will not only describe the two theoretical positions which are summarized above, but will also adopt an interpretative approach to trace their possible causes and to grasp their effects on the development of the discipline, particularly with regards to the theories of value which is adopted by the Italian accounting over the analyzed period. In the authors' opinion, the attention paid by the most authoritative Italian accounting scholars to the epistemological theme of relationships between accounting and its similar sciences can be explained by at least two different causes: the influence which is exercised by the philosophical studies and the aspiration of accounting for scientific and academic recognition.
文摘2012 is a year of celebrate centenary of X-ray discovery information about Laue's (Fridrich and Knipping) experiment was This discovery spread quickly in different countries. The history of written in the paper. Also history mention of Laue's experiment in Russia was presented. The system group of X-ray diffraction was created in 1919/1920 in Petrograd (A. Ioffe, State Physical Technical Institute) and Moscow. Themes of research results, scientific newness and scientific rate were presented. The organization, political and other reasons which retarded the active progress of the method in 1930 were described. Initial stage of progress of the method in Russia-USSR was studied by historian of science partly. The reasons of it are: closed of scientific community, political system of country, Cyrillic barrier, etc.. This paper acquaints western scientific community with non-famous Russian materials on theme.

文摘The development history of education is actually a history of the change of media technology.From the perspective of historical development,different periods of media technology have different forms of education.As the two core elements of education,curriculum and teaching are also deeply influenced by the development of media technology.With the continuous emergence of new media,especially in the context of artificial intelligence,the curriculum has experienced the change from attaching importance to subject knowledge to the cultivation of students’innovation ability and core literacy;from static,paper-based,single to dynamic,online and network-based curriculum form;from fixed,unified,limited to personalized,unlimited and open curriculum change is tolerated.Teaching has also experienced two major changes:the optimization of teaching forms and the adjustment of teaching subject role.In order to actively cater to the development of the future science and technology society,the future curriculum and teaching should focus on sustainable development education;focus on the cultivation of key abilities in the 21st century;focus on improving the“three scientific and technological literacy”education;and strengthen the humanistic care of curriculum and teaching.
文摘Geology is perhaps the most fascinating of the natural sciences, due to its all-encompassing nature. Virtually all human activities that occur on planet Earth--including agriculture, energy and mineral resource exploration and extraction; environmental and public policy on natural resources management and protection; land use planning; infrastructure development; and ecological tourism--all depend on various aspects of geology and its sub-disciplines. Due to the importance of geology in the daily lives of human beings, it is imperative that all persons develop at least a basic understanding of the science. In this paper, the current efforts for promoting public understanding in geology will be examined, with offerings of alternatives and supplements to these efforts. Information from the science education sub-disciplines of HPS (history, philosophy and sociology) of science, and informal/free-choice learning will be woven into the framework of the geology-public understanding idea.
文摘This article explores both the personal and transnational dimensions of domestic science education and study abroad for the pioneering generation of Chinese women in science.By focusing on women’s unique calculus of risk and reward,the article not only distinguishes Chinese women’s experiences from those of their male counterparts but also delineates the special contours of the Chinese case within the global advancement of women in science.The article begins by outlining some of the features and dynamics of early Chinese girls’schools that affected students’interest in and preparation for further scientific study.Then it traces the emerging college-level opportunities that made it possible for women who were studying science in China to contemplate advanced work overseas.Turning to study abroad,the article highlights the radicalness of the decision to study abroad by examining the impact of both family background and national circumstances on Chinese women’s strategies of mobility.The article argues that if we are to take women’s experiences seriously,we cannot just look at scientific pursuits in terms of achievements in the development of Chinese science,we also need to consider the ways that·scientific ambitions forced individuals—both male and female—to navigate and reimagine multiple social norms and expectations.
文摘It has been recognized that self-reliance and self-improvement of science and technology is a necessary choice of taking the independent innovation path with Chinese characteristics in the new era,which provides strategic support for the comprehensive construction of a modern socialist country.Containing the theoretical truth of the Chinese Marxist view of science and technology in the 21st century,it follows the 70-year development path of science and technology in New China,and responds to the scientific and technological strategic choice of building a modern socialist country in an all-round way in the new era.This is not only a theoretical deepening of General Secretary Xi Jinping’s important statement on scientific and technological innovation,but also a practical guide for China to implement scientific and technological innovation in the new era.

文摘The art of ceramics originates from the basic activities of human beings,and uses the tools,following the methods,and the visual production activities combined with aesthetics.Modern technology has spawned new ceramic decoration methods and provided new ideas for artistic creation.Ceramic art relies on ceramic crafts.As the most technical form of many art categories,it is the representative of the“Combination of Art and Crafts”of arts and crafts,and it is the perfect embodiment of“Beauty”in the space-time carrier.The history of Chinese ceramic glaze shows that the study of the history of ceramic technology should rely on the aesthetics of ceramics,and the problems related to the interpretation of modern ceramic art cannot be separated from the context of the history of ceramic technology.
文摘The Institute for the History of Natural Sciences in Beijing celebrated the sixtieth anniversary of its founding in 1957 with an international symposium devoted to“China and the World in the Global History of Science and Technology.”2 This contribution to that symposium focuses on the roles that historians of mathematics,East and West,have played in bringing the importance of mathematics in China to the attention of the world at large.It concludes by discussing a controversy surrounding the diagram and purported“proof”given in the ancient mathematical classic,the Zhoubi suanjing周髀算經(Mathematical classic of Zhou’s gnomon),of the gou-gu theorem that appeared in volume 3 of Joseph Needham’s Science and Civilisation in China,published in 1959.
