Draft genome sequence of subterranean clover, a reference for genus Trifolium
Publisher: Springer Science and Business Media LLC
Date: 22-08-2016
DOI: 10.1038/SREP30358
Abstract: Clovers (genus Trifolium ) are widely cultivated across the world as forage legumes and make a large contribution to livestock feed production and soil improvement. Subterranean clover ( T. subterraneum L.) is well suited for genomic and genetic studies as a reference species in the Trifolium genus, because it is an annual with a simple genome structure (autogamous and diploid), unlike the other economically important perennial forage clovers, red clover ( T. pratense ) and white clover ( T. repens ). This report represents the first draft genome sequence of subterranean clover. The 471.8 Mb assembled sequence covers 85.4% of the subterranean clover genome and contains 42,706 genes. Eight pseudomolecules of 401.1 Mb in length were constructed, based on a linkage map consisting of 35,341 SNPs. The comparative genomic analysis revealed that different clover chromosomes showed different degrees of conservation with other Papilionoideae species. These results provide a reference for genetic and genomic analyses in the genus Trifolium and new insights into evolutionary ergence in Papilionoideae species.

Dynamic analysis of a smooth penetrometer free-falling into uniform clay
Publisher: Thomas Telford Ltd.
Date: 10-2012
Abstract: The finite-element analysis of free-falling objects penetrating soil deposits is one of the most sophisticated and challenging problems in geomechanics. A robust numerical method will be described here for dealing with such complex and difficult problems. The approach is based on the arbitrary Lagrangian–Eulerian (ALE) method of analysis, the main features and challenges of which are described briefly in the paper. The ALE method is then employed to perform a parametric study of a perfectly smooth penetrometer free-falling into a uniform layer of clay, which deforms under undrained conditions. The effect of the mechanical properties of the clay soil on the penetration characteristics is presented, and an approximate, closed-form expression is derived for the dynamic penetration factor, N dp . Comparisons are made between the deduced values of N dp and published values of the conventional cone factor, N c , and comparisons are made with experimental data to validate the approach.

Rail Degradation Prediction Models for Tram System: Melbourne Case Study
Publisher: Hindawi Limited
Date: 2018
DOI: 10.1155/2018/6340504
Abstract: Tram is classified as a light rail mode of transportation. Tram tracks experience high acceleration and deceleration forces of locomotives and wagons within their service life and also share their route with other vehicles. This results in higher rates of degradation in tram tracks compared to the degradation rate in heavy rail tracks. In this research, gauge deviation is employed as a representative of track geometry irregularities for the predication of the tram track degradation. Data sets used in this research were sourced from Melbourne’s tram system. For model development, the data of approximately 250 km of tram tracks are used. Two different models including a regression model and an Artificial Neural Networks (ANN) model have been applied for predicting tram track gauge deviation. According to the results, the performances of the regression models are similar to the ANN models. The determination coefficients of the developed models are above 0.7.

DOI: 10.4028/WWW.SCIENTIFIC.NET/AMM.553.401
Abstract: This paper addresses the application of high-order elements in the analysis of soil penetration problems, particularly those involving inertia forces and large deformations. Among others, 15-node triangular elements are formulated within an Arbitrary Lagrangian-Eulerian finite element method. Preliminary studies indicate that high-order elements can significantly decrease the analysis time without significant loss of accuracy.
Effect of Dimension Variables on the Behaviour of Slopes Stabilised by an Integrated Method Combining Gabion-Faced Geogrid-Reinforced Retaining Wall with Embedded Piles
Publisher: Springer Science and Business Media LLC
Date: 10-2022
DOI: 10.1007/S40891-022-00411-0
Abstract: Severe slope instability exists in the area of South Gippsland in Victoria state located in south-east Australia. An integrated slope-stabilisation method, which includes a pile-retaining structure installed at toe of the gabion-faced geogrid-reinforced retaining wall, has widely been used in this district. A continuous steel rail wall embedded in the concrete pile then provides lateral support to the retaining wall. The effectiveness of the integrated method is first illustrated by comparing the slope stability evaluated by strength reduction method and behaviours of the slope obtained by elastoplastic analysis. A series of parametric studies are then performed to investigate effects of facing inclinations, embedded geogrid length, and vertical spacing of geogrid layers on the stability and behaviour of the slope and the behaviour of the pile under various uniform surcharge load conditions. The numerical results indicate that additional contribution from piles can increase the stability of the slope up to $$42.9\\%$$ 42.9 % . The dimensional variables of gabion-faced geogrid-reinforced retaining wall also impose significant impact on the behaviour of slopes and piles, and the effect of each variable has also been quantitatively evaluated and qualitatively described. The effect of the geogrid amount on behaviours of slopes and piles has also been investigated through the comparison between two slope configurations with maximum and minimum geogrid amount. The results from the parametric studies can then be used as a design reference for the future applications of this integrated slope-stabilisation method.

Effect of Various Rainfall Conditions on the Roadside Stabilisation of Slopes in Gippsland
Publisher: Springer Science and Business Media LLC
Date: 30-08-2023
DOI: 10.1007/S40999-022-00752-X
Abstract: A distinctive slope stabilisation method that integrates two well-developed methods for slope stabilisation is analysed in this paper. The slope stabilisation method utilises embedded piles and geogrid-reinforced retaining walls with gabion basket wall facing. To study the effect of this integrated slope stabilisation method on the stability of the slope under the negative impacts of rainfall, a three-dimensional finite element model with fluid–solid coupling is adopted to indicate the rainfall infiltration process and investigate the corresponding slope responses. The shear strength reduction method is applied after fluid–solid coupling analysis to investigate the impact of various rainfall intensities and rainfall patterns on the stability of slopes with different configurations. The results from the comparison of slope responses among various configurations indicate that under the highest rainfall intensity, the integrated method improves the stability of the slope up to $$41.2\\%$$ 41.2 % and restrains the displacement increment of the road edge to a maximum of $$12.5$$ 12.5 mm. The most critical rainfall pattern for the stability of the slope has also been recognised in terms of the factor of safety and the variation in the negative pore-water pressure of the slope. The numerical results indicate that the back-loaded rainfall pattern always yields the lowest factor of safety and induces the highest loss of matric suction, which can be $$23$$ 23 kPa at the toe of the slope. Moreover, a comparison between two construction scenarios under various rainfall intensities was also conducted, which demonstrates that the reinforced filled slope configuration is preferable when the site conditions permit.
