The engineering geology of the lower greensand of south-east England : with particular reference to the microfabric, geotechnical index properties and shear strength characteristics
No full textThis is an Engineering Geological study of the arenaceous members of the Lower Greensand (Lower Cretaceous) of South-East England. The investigations carried out were of the microfabric, geotechnical index properties and shear strength characteristics of the Folkestone Beds, Hythe Beds and Sandgate Beds. These tend to fall in the interesting transitional area between sands and sandstones. The Folkestone Beds are quartz rich, medium to fine-medium sands that contain iron-oxide and kaolinite cement. They have been subject to mechanical compaction which has led to grain re-arrangement, increases in the number of straight contacts and porosity reduction. Further reductions in porosity and increases of straight contacts were due to chemical compaction by pressure solution. Decreases in Tangential Index (the number of tangential contacts amongst all grain to grain contacts) result from increases in compaction. The interlocked nature of many of the sands results in a significant cohesion while some cohesion is also provided by the cementation. Large gains in cohesive intercept values, obtained by direct shear testing, occur as the Tangential Index reduces below 34%. By contrast, increases in cohesion with cement contacts is of a lesser order. In the sands that contain significant proportions of cement, compaction processes have been inhibited. This has led to increases in the Tangential Index and decreases in cohesion due to interlocking. Two of the sands contain little intergranular cement, are highly interlocked and classed as `locked' sands. The majority of the Folkestone Beds are classed as slightly cemented sands. The Hythe Beds are fine grained, glauconitic sandstones which contain quartz cement in the form of syntaxial overgrowths. They have been subject to both mechanical and chemical compaction processes resulting in increasing numbers of straight and concavo-convex contacts and decreases in porosity. Chemical compaction leading to pressure solution is the probable source of the quartz cements. The Hythe Beds with quartz cement have the highest uniaxial compressive strengths and increases in quartz cement content correspond to increasing strength values. The Sandgate Beds are glauconitic and calcareous cemented sands and sandstones. They contain little quartz cement but significant amounts of calcitic cement. The cement content in these sediments is associated with higher values of Tangential Index and is presumed to be due to the early cementation inhibiting the development of an interlocked fabric. The higher Tangential Index, despite the calcite content, results in lower uniaxial compressive strengths demonstrating the importance of interlocking to the development of strength.</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
Field trials and development of a hydrostatic pressure machine
No full textHydrostatic Pressure Machines (HPM), are a class of hydropower energy converter designed to operate at sites with heads below 3 meters; sites receiving increasing interest as the demand for power from renewable energy sources grows.The HPM is a ‘Pressure machine’, applying the pressure produced by differing water levels at a site, directly to the blades of the device to extract power. Prior to the current research, these machines had only existing as laboratory models.This thesis describes the design, construction and testing of a 5 kW prototype HPM installed at a re-activated mill site in Bavaria. Observations and performance test results from this full scale unit are then compared with the results of scale model tests carried out in the laboratory.New theory is developed to account for the geometry of the prototype machine and the variations in water levels encountered during operation. This is found to give very good agreement with performance measurements from both prototype and model tests, with no scale effects identified between the scales over the normal operating range of the machine.Several alternative rotor designs are tested at model scale, which demonstrate useful performance gains compared with the prototype machine.Direct blade force and cell pressure measurements are also obtained during model operation which has increased our understanding of the energy exchanges taking place between rotor and fluid within the machine. This in turn helps to identify the key machine geometries which impact performance
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
