Mineralogical characteristics of continental shale: a case study in Yan-Chang Formation, Ordos Basin
No full textThe Chang 7 Member of the Yan-Chang Formation (Yan-Chang #7 Member), which is located in the central south of the Ordos Basin (China), is assessed for its potential as a shale gas resource. The characteristics and spatial variability of mineral components in this continental shale formation play a crucial role in evaluating and characterising the shale reservoirs. We collected 64 shale core samples from 30 representative sampling sites located in the central south of the Ordos Basin using X-ray diffraction and field emission scanning electron microscopy to study the mineral compositions, vertical/planar variations of minerals, and the major controlling factors that result in such variations. Based on the relative fractions of the dominant minerals, the shale rocks can be classified into four categories: quartz-rich (type #1), illite/chlorite-rich (type #2), illite–smectite mixed-layer-rich (type #3) and feldspar-rich (type #4). In general, type #1 is mainly located in the northwest of the study area, type #4 is mainly located in the south of the study area, and types #2 and #3 are sandwiched between types #1 and #4. In the centre of the basin, the illite content increases with burial depth and the conversion from smectite to illite, which is experimentally confirmed in this study, enhances the surface porosity of shale. The major factors influencing the properties and spatial variability of the mineral components include sedimentary environment, provenance and diagenesis. Compared with marine shales in China (e.g. Longmaxi marine shales), the Yan-Chang #7 Member continental shale has a higher clay content, but lower calcite, dolomite and pyrite contents. The brittleness indexes of type #1 shale in Wuqi and its surrounding areas are marginally higher than that of Longmaxi marine shales, which makes the type #1 shale in the Wuqi and its surrounding areas slightly easier to fracture than the Longmaxi marine shales.</p
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
An Integrated Static Reservoir Modelling of Yan Chang formation, Ordos Basin, China
No full textUnderstanding and applying integrated data in reservoir characterization and static geomodeling is essential in order to visualized and calculate the economic value of a field, in this case Yan Chang, Chang 3 formation. Hence, the main purpose for this project is to use integrated raw data by performing geophysical and petrophysical evaluation for Chang 3 and build a static model. The method used is basic seismic interpretation skill for geophysical evaluation including horizon picking for top and base for Chang 3, regional fault picking, and time depth conversion of the top and base of Chang 3 surfaces generated from the picked horizon. While in petrophyscial evaluation, it included shale volume, porosity and permeability log derivation with the regression equation of porosity-permeability crossplot. In reservoir characterization, it is mainly based on analogue studies and Vsh and porosity log based on the concept of increasing clay away from channel. It yield a static model with facies model mainly channel trend feeding in reservoir sand, lithofacies model with rock type found in core description with distinct porosity ranges from 7.59% to 12.55 while permeability model with the regression equation interpreted in the crossplot giving good relationship between porosity and permeability in the model. Key aspect of this project is that the built a Chang 3 static model that can be serve as an input for dynamic model for flow simulation and as well as for further reservoir evaluation mainly volume assessment in Chang 3 area
Oncidium Health Management

祕魯、巴西、阿根廷等國，由平地到海拔2000 公尺以上的冷涼高地都有其蹤跡，
各原種之生態習性變化很大。目前本省經濟生產的文心蘭，不論是切花或盆花，
大都是經過雜交育種選拔出來的品種。國內於民國六十五年自泰國引進切花品種

題。
Oncidium orchid, Oncidium spp., the genus Oncidium of the orchid family
(Orchidaceae), are the native species of tropical America Mexico, Brazil and
Bolivia .Most species in this genus are epiphytes or terrestrials with a sympodial
growth habit which belong to C3 plant. The genus comprise approximately 700 native
species and has widespread in tropical America Florida, Mexico, Paraguay, Peru,
Brazil and Argentina these countries. Oncidium species could live in different habitat.
They could be found on the ground or up on 2000 meter highland. Recently the
cultivated Oncidium species in Taiwan, as cut flower or pot flower, are mostly hybrid
and selected from cross breading. Onc. ‘Gower Ramsey which was imported from
Thailand in 1976 has been a popular species to growers in Taiwan as cut flower, after
being exported to Japan since 1991 the cultivation output has enhanced every year,
thus the cultivation area now has enlarged above 300 ha. Onc. ‘Gower Ramsey’ was
written a glorious history in Japan’s Oncidium import market , its cultivation area was
more than 200 ha in Taiwan and we exported 20 million 640 thousand stalks to Japan
in 2007, that was 87.6% of Japen’s Oncidium import volume that year, with one
species, single color, only market and unique victory. Anyway, the cultivation output
enhance is important but the harvest season is limited from May to June and
September to October, therefore the large quantities always comes with lower price.
Also, Net room cultivation in summer cause shorter vase live is another problem.
Thus, to create a nature health cultivation system on Oncidium is an important issue
now
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
