Failure mechanism and simulation for long run-out of the catastrophic rock landslide in the Shanyang Vanadium Mine,China

On 12th August 2015,a massive rapid long run-out rock landslide occurred in the Shanyang Vanadium Mine in Shaanxi Province,China,which claimed the lives of 65 miners.No heavy rainfalls,earthquakes,and mining blasts were recorded before the incident.Therefore,the failure mechanism and the cause of the long run-out movement are always in arguments.In this paper,we conducted a detailed field investigation,laboratory tests,block theory analysis,and numerical simulation to investigate the failure and long run-out mechanisms of the landslide.The field investigation results show that the source material of the rock landslide is a huge dolomite wedge block bedding on siliceous shale layers.Uniaxial compression tests indicate that the uniaxial compression strength of the intact dolomite is 130-140MPa and the dolomite shows a brittle failure mode.Due to the progressive downward erosion of the gully,the dolomite rock bridge at the slope toe became thinner.As the compression stress in the dolomite bridge increased to surpass its strength,the brittle failure of the bridge occurred.Then huge potential energy was released following the disintegration of the landslide,which led to the high acceleration of this rock landslide.The 3D discrete element simulation results suggest that the low intergranular friction contributes to the long run-out movement of this rock landslide.

The Criticism of Social Realities in the Three Worlds after the Human World of The Journey to the West

The three worlds after the human world in The Journey to the West, in spite of their religious elements, their implicit moralizing, and their involved allegory, hold up a mirror to the social vices of the author's day, showing on the one hand the corruption, injustice, ava rice, lust, faction, perfidiousness and cruelty among the ruling classes, and on the other hand the miseries of the oppressed.

The Criticism of Social Realities in the Human World of The Journey to the West

Given the descriptions of all those unworthy kings in the human world,The Journey to the West is more of a realistic work of fiction than a fantasy.Though the story comprises many superstitious elements,it is told in a very vivid and convincing way and it holds numerous indirect references to the conditions of the author's own day.The book is the author's most forceful means of criticizing the ugly appearances of the ruling classes of his time.

A Brief Analysis of the Themes of The Journey to the West

The Journey to the West has adopted a conventional theme--life is a journey;in order to deliver one's soul,one has to go on the path of salvation.The purpose of this paper is to examine what steps the author has taken to enlighten the readers as to the progress of spiritual salvation.In view of this purpose,the analysis will be focused on the preaching of religious doctrines and the criticism of social realities in the novel.

A prediction model for horizontal run-out distance of landslides triggered by Wenchuan earthquake

The peak ground acceleration （PGA）, the volume of a sliding mass V, the height of a mountain HL and the slope angle θ of a mountain are four important parameters affecting the horizontal run-out distance of a landslide L. Correlations among them are studied statistically based on field investigations from 67 landslides triggered by the ground shaking and other factors during the Wenchuan earthquake, and then a prediction model for horizontal run-out distance L is developed in this study. This model gives due consideration to the implications of the above four parameters on the horizontal run-out distance L and the validity of the model is verified by the Donghekou and Magong Woqian landslides. At the same time, the advantages of the model are shown by comparing it with two other common prediction methods. The major findings drawn from the analyses and comparisons are： （1） an exponential relationship exists between L and log V, L and log HL, L and log PGA separately, but a negative exponential relationship exists between L and log tan0, which agrees with the statistical results; and （2） according to the analysis results of the relative relationship between the height of a mountain （H） and the place where the landslides occur, the probabilities at distances of2H/3-H, H/3-2H/3, and O-H/3 are 70.8%, 15.4%, and 13.8%, respectively, revealing that most landslides occurred at a distance of H/2-H. This prediction model can provide an effective technical support for the prevention and mitigation of landslide hazards.

Advanced run-out table cooling technology based on ultra fast cooling and laminar cooling in hot strip mill

In order to meet the severe requirements of market and reduce production costs of high quality steels,advanced run-out table cooling based on ultra fast cooling(UFC) and laminar cooling(LC) was proposed and applied to industrial production.Cooling mechanism of UFC and LC was introduced first,and then the control system and control models were described.By using UFC and LC,low-cost Q345B strips had been produced in a large scale,and industrial trials of producing low-cost dual phase strips were completed successfully.Application results show that the ultra fast cooling is uniform along the strip width and length,and does not affect the flatness of strips.The run-out table cooling system runs stably with a high precision,and makes it possible for the user to develop more high quality steels with low costs.

Coupled models of heat transfer and phase transformation for the run-out table in hot rolling

Mathematical models are been proposed to simulate the thermal and metallurgical behaviors of the strip occtLrring on the run-out table （ROT） in a hot strip mill. A variational method is utilized for the discretization of the governing transient conduction-convection equation, with heat transfer coefficients adaptively determined by the actual mill data. To consider the thermal effect of phase transformation during cooling, a constitutive equation for describing austenite decomposition kinetics of steel in air and water cooling zones is coupled with the heat transfer model. As the basic required inputs in the numerical simulations, thermal material properties are experimentally measured for three carbon steels and the least squares method is used to statistically derive regression models for the properties, including specific heat and thermal conductivity. The numerical simulation and experimental results show that the setup accuracy of the temperature prediction system of ROT is effectively improved.

New journey,new mission: bolstering international communication about mental health

In the wake of the rapid economy and society development, phenomena such as industri-alisation, urbanisation, marketisation and the ageing of the population have shown an accelerating trend. As a result, mental health issues due to these phenomena are increasingly serious, making mental health both concerning public health and societal issues that have a great impact on economic and social development.^1 In 2014, there were 16 million persons with severe mental disor-ders in China.

The second part focuses on the contradictory relationship in parents and sons. The contradictions between brothers are discussed in the third part. Through the study of the causes of the contradictory relationship among family members, the tragedy of the characters in the play will be explored to the readers, which is also the tragedy of modern Ameri can people.

Cultural Transfer of Specific Terms Translation in The Journey to the West(C-E)

Translation study has long been focused on the linguistic difference between the ST and TT, to achieve"faithfulness"of the original. Translation is regarded as a second-hand copy the source text. Since Susan Bassnett puts forward cultural transfer as an approach in translation study, it begins to shift from linguistic study to comparative literary study. The process of translation involved in making another culture comprehensible entails varying degrees of violence, especially when culture being translated is constituted as that of the"other". The Journey to the West, a traditional Chinese classic contains numerous cultural-specific terms. Translators with different cultural identity mainly adopt domestication to provide easy access to the target readers, revealing the subjectivity and ideology of the translators and their cultures.

Reading as Transformational Journey From Homer to Borges

The transformational journey archetype begins long before literature in rites of initiation when a child undergoes a journey full of tests and temptations, perilous encounters in an underworld, and visions that transform the child into a member of a tribe. Before this archetype is translated by the written word into literature, the telling of the story is not just the account of something that happened long ago in the past, but an actual reenactment of the events for the audience. The journey archetype appears in the earliest example of literature, Homer＇s Odyssey, where Homer makes the readers both an observer and participant in the transformation. The journey does not always, as in rites of initiation, involve a child and occur only once in life. Instead, the journey may begin in death and trauma and involve a person who must resume that journey over again as an adult. Such is the fate of Aeneas in Virgil＇s Aeneid whose transformative journey begins with the burning towers of Troy. In these two early epics the heroes suffer the loss of an older world and must resume their pursuit of new identities in a new world after descending to a land of death or underworld to consult ancestor figures who prepare them for the transition to a new life, identity, and destiny. The reader of these works participates in the journeys the heroes undertake and learns to renew contact with the sources of life and consciousness in myth, magic, and vision. Dante＇s journey through the Inferno to his vision of God in Paradiso is a culmination of this transformative experience and vision, whose intent is to transform us as well through imaginative and intellectual participation in the journey. In Jorge Luis Borges＇s parody of Dante in his story, ＂El Aleph＂, Borges goes beyond Dante in making the reader, not only a participant in the journey and vision, but a ＂writer＂ whom Borges evokes to transform the impossible vision of the Aleph into an illusion of reality. Unlike Dante＇s positive transformational vision of the universe as a harmonious cosmos embraced within the vision of God as if it were a book uniting its multiple pages in one binding, the vision of the Aleph confronts the protagonist and readers with a universe that is random and chaotic, a vision that is disillusioning rather than transformational.
