Chemical Composition Analysis

The process mineralogy of potassium-rich shale from Chaoyang of Liaoning, China, was studied. Research results showed there are much less variety and smaller quantities in mineral compositions. Calculated mineral composition by means of chemical composition analysis combined with XRD, MLA, IR and TG-DSC analyses showed that main minerals with were Potassium-feldspar, muscovite, biotite and illite, and gangue minerals were quartz and small amounts of hematite. Potassium-rich minerals such as potassium-feldspar and muscovite contact smoothly with quartz respectively, and there was the direction arrangement among potassium-feldspar, quartz and muscovite in the shale. And quartz and hematite were main cement in the shale. The influences of the research results on the potassium extraction from potassium-rich shale were distinct.

Abstract: Authors from different countries have published their papers in English, aiming to promote their research results widely and to become internationally known by their peers. It is also true that, although they are aware of the English terminology used in their respective field, some authors still struggle with some features of academic writing such as collocations. Thus, this paper presents a discussion on the underuse and overuse traces of academic collocations by Brazilian authors who had their articles published in English on an open electronic library of scientific journals. In order to analyse the collocations used by these researchers, we compiled a 906,035-word corpus from eight different academic areas. The collocations observed were statistically compared to those from an academic corpus of English writings which contains texts produced by English-speaking authors. Results showed that there are more collocations underused than overused by the authors. The analysis proved that the collocation repertoire of researchers could be broadened by being pointed out during academic writing workshops.Keywords: academic collocations; research paper writing; corpus linguistics.Resumo: Autores de vários países têm publicado seus artigos científicos em inglês com o intuito de promover amplamente os resultados de suas pesquisas dentre a comunidade científica internacional. É verdade que, embora estejam cientes da terminologia utilizada no respectivo campo de pesquisa, alguns autores ainda apresentam dificuldade em lidar com certas características da escrita acadêmica, como o uso das colocações. Este artigo apresenta uma discussão sobre traços de sobreuso e subuso de colocações acadêmicas utilizadas por autores brasileiros que têm seus artigos publicados em inglês numa plataforma eletrônica aberta de artigos científicos. Para analisar as colocações utilizadas por estes pesquisadores, compilamos um corpus de 906.000 palavras a partir de oito áreas científicas. As colocações analisadas foram comparadas estatisticamente com as colocações de um corpus acadêmico de inglês que contém textos escritos por autores anglófonos. Os resultados mostraram que há mais traços de subuso que sobreuso de colocações acadêmicas utilizadas pelos pesquisadores e este repertório poderia ser ampliado se fossem destacadas durante cursos de escrita acadêmica em língua inglesa.Palavras-chave: colocações acadêmicas; escrita de artigos científicos; linguística de corpus.

The 19Th Century

The research and commercial activity in the Scandinavian portion of the Arctic increased appreciably in the last decades of the 19th century and up until the 1920s. Not unexpectedly, the idea arose during this period to bring the largest group of the as yet unclaimed Arctic islands, Spitsbergen, under Norwegian or Swedish control. Norwegian political ambitions in the far north seem to have expanded proportionally with economic and scientific activity. What role did science play in this process? In the contest to win Svalbard, Norwegian authorities deliberately used research results and research activity as justification that Spitsbergen was Norwegian. Also, Spitsbergen researchers worked systematically towards a Norwegian conquest of the archipelago, economic and cultural at first, but ultimately political.

The Cornell Net Carbohydrate and Protein System (CNCPS) model has been increasingly used in tropical regions for dairy and beef production. However, the lack of appropriate characterization of the feeds has restricted its application. The objective of this study was to develop and evaluate a feed library containing feeds commonly used in tropical regions with characteristics needed as inputs for the CNCPS. Feed composition data collected from laboratory databases and from experiments published in scientific journals were used to develop this tropical feed library. The total digestible nutrients (TDN) predicted at 1x intake of maintenance requirement with the CNCPS model agreed with those predicted by the Weiss et al. (1992) equation (r² of 92.7%, MSE of 13, and bias of 0.8%) over all feeds. However, the regression r² of the tabular TDN values and the TDN predicted by the CNCPS model or with the Weiss equation were much lower (58.1 and 67.5%, respectively). A thorough comparison between observed and predicted TDN was not possible because of insufficient data to characterize the feeds as required by our models. When we used the mean chemical composition values from the literature data, the TDN predicted by our models did not agree with the measured values. We conclude using the TDN values calculated using the Weiss equation and the CNCPS model that are based on the actual chemical composition of the feeds result in energy values that more accurately represent the feeds being used in specific production situations than do the tabular values. Few papers published in Latin America journals that were used in this study reported information need by models such as the CNCPS.

AbstractThe age and chemical composition of the stars in present-day galaxies carry important clues about their star formation processes. The latest generation of population synthesis models have allowed to derive age and stellar metallicity estimates for large samples of low-redshift galaxies. After reviewing the main results about the distribution in ages and metallicities as a function of galaxy mass, I will concentrate on recent analysis that aims at disentangling the dependences of stellar populations properties on environment and on galaxy stellar mass. Finally, new models that predict the response of the full spectrum to variations in [α/Fe] will allow us to derive accurate estimates of elements abundance ratios and gain deeper insight into the timescales of star formation cessation.

Purpose. The presentation of challenges with which scientific journals and - more broadly - scientific communication, will have to face in the substantive, technological and financial sphere in the conditions of constant evolution of the digital world, dynamic development of new information systems in science (e-library, library 2.0) and new phenomena conditioning the behaviour of Internet users. Method. The views presented in the article are the result of a review of literature regarding scientific journals and empirical research, which was conducted from April to August 2018 among 132 authors representing the world of science and economic practices. Findings. The open access (OA) movement has caused significant changes in the behaviour of people of science in publishing and depositing research results. The prospect of taking over all the functions of scientific journals by scientific repositories still seems to be distant due to the lack of alternative methods for assessing the quality of scientific publications. There are doubts about the division into scientific, institutional repositories and the repositories belonging to scientific journals, which results from unclear business models of individual solutions. The phenomenon of self-publishing is stimulated by the dynamic development of research carried out by business units, skilfully analysing the resources of large data sets and successfully popularising research results in social repositories. This is new quality in the area of information exchange, which requires rapid adaptation on scientific grounds. An insufficiently implemented postulate to popularise scientific knowledge and its transfer to business practice remains an equally important challenge. Research and conclusions limitations. The results of the survey based on the respondents’ subjective assessment should be treated with caution and do not allow to draw general conclusions. The research revealed significant discrepancies in respondents' opinions regarding the future of scientific journals and their prospects for functioning in new information systems. The highest doubts concern the quality assessment system of scientific publications and the business model of scientific repositories: the significant number of stakeholders of the scientific communication system, dispersed in various scientific, political and economic systems, further limits the possibility of formulating unambiguous decisions in this respect. Originality. The presented article formulates challenges for scientific journals whose functions are being increasingly taken over by scientific and social repositories. In contrast to the previously published works, this suggests solutions in the field of artificial intelligence, which will enable complete change in the way of publishing and validation of knowledge as well as quality control of scientific research.

Resources Development

The purposes of this research are to find out a) the strategies in human resources development to improve the quality of Postgraduate lecturers at IAIN Curup, (b) supporting factors, and  (c) the obstacles of human rights development. Using qualitative research method, the data were collected through interviews and documentary study. The research results showed that the strategies used for developing human resources or improving the quality of postgraduate lecturers include: (1) organizing the research methodology training; (2) holding the scientific journal writing training; (3) holding book writing/teaching materials training; and (4) involving lecturers into National and International Seminars. Supporting factors for human resource development are (a) high commitmentof  IAIN Curup Postgraduate management, (b) organization and socialization activities for professors acceleration programs, and (c) conducting coaching clinic activities for reputable international publications, in the form of programs to publish research results in reputable international scientific journals. Meanwhile, the obstacles are inadequate infrastructure and limited funds because there are still few students and tuition fee is still in the third category in the Ministry of Religion's General Cost Standards (SBU). The funds have not been fully handed over to the Postgraduate, because it is still centralized at the Institute, if the Postgraduate organize an activity, it must be approved by the Institute before it run.
