Research on characters of surrounding rock in complex geology conditions and supporting time

The methods combined by test, field monitoring and theoretical analysis were adopted to do the systemic research on the rock mass from micro-structure to macro-deformation, and rheological model of Jinchuan rock mass was established to discuss the reasonable supporting time. Resuhs show that supporting after suitable stress and displacement release can benefit for the long-term stability of surrounding rock.

Dynamic subsidence basins in coal mines based on rock mass rheological theory

In order to investigate the surface deformation caused by coal mining and to reduce environmental damage, more accurate information of dynamic subsidence basins, caused by coal mining, is needed. Based on theological theory, we discuss surface deformation mechanism of dynamic subsidence on the assumption that both the roof and the coal seam are visco-elastic media, put forward the idea that the principle of surface deformation is similar to that of roofs, except for their parameters. Therefore, a surface deforma- tion equation can be obtained, given the equation of the roof deformation derived.from using a HIM rhe- ological model. In the end, we apply the equation of surface deformation as a practical subsidence prediction in a coal mine. Given the theologic properties of a rock mass, the results of our research of a dynamic subsidence basin can predict the development of surface deformation as a function of time, which is more important than the ultimate subsidence itself. The results indicate that using rheological theory to calculate the deformation of a dynamic subsidence basin is suitable and provides some reference for surface deformation of dynamic subsidence basins.

STEADY-SHEAR VISCOSITY AND TRANSIENT STRESS RESPONSE FOR ELASTO-THIXOTROPIC FLUIDS

A phenomenological model for dispersed systems which exhibit complex theological behaviour such as shear and time-dependent viscosity, yield stress, and elasticity is proposed. The model extends the Quemeda model to describe the viscosity function with a structural parameter λ which varies according to differ- ent kinetic orders of particle aggregation and segregation. The transient stress response is obtained by solving an instantaneous Maxwell model with an assumed shear modulus function G of the same form as the viscosity function η. Accuracy of the proposed model is verified experimentally with the results obtained for two oil (creosote)/water emulsions. The model that gives the best fit of experimental data appears to be the one with kinetic orders n = m = 2.

Rheological Behavior of Zero Cement Al_2O_3-MgO Castables

Al2O3 -MgO castables have been widely used for working linings of steel ladle due to their superior hot strength and corrosion resistance. In this- work, effects of＂ microsilica, ultrafine alumina and MgO fines additions on the rh, eological behavior of the castables were investi- gated by means of IBB rheometer V1. 0 to measure torque （shear stress） under varying shear rates. The re- sults show that rheological properties of castables at varying shear rates are significantly improved with increase of microsilica additions （from 1 mass% to 5 mass% ） and corresponding decrease in water addition; there is only little change in rheological behavior with variation of ultrafine alumina and MgO fines additions. Optimum ultrafine alumina and microsilica additions are recommended for castables with good rheological behavior.

Influences of Polycarboxylate Superplasticizers on Rheological Behavior of Low-cement Castables

Influences of different superplasticizers （ STP. KSJSTO and LMS-P） on rheological behavior of low-cement castables and the mechanisms were analyzed. The shear stress and viscosity under different shear rates of matrix slurry were determined using a NXS-I IA rotary viscometer. Effects of different admixtures on the rheological properties of slurry was analyzed theoretically. Sodium tripolyphosphate and poly＇carboxylate superplasticizers KS-JSTO and LMS-P） can improve the fluidity and initial setting time. With STP. the slurry is plastic flow. With KS-JS70 or LMS-P increasing, the slurrv changes from plastic.flow, pseudoplastic flow to dilatant flow successively. Th, e optimum dosages of STP. KS-JSTO and LMS-P are 0. 15%. 0. 25% and 0. 40%, respectively. KS-JS70 and LMS-P can significantly reduce the slurry viscosity and shear stress to improve the workability of construction. Both shear stress and viscosity shall be taken into account for on-site construction.

Rheological Behavior of the Guanidio Polyelectrolytes

The rheological behavior of polyhexamethylene guanidine hydrochloride (PHGC) and polyhexamethylene guanidine stearate (PHGS) has been investigated using the capillary rheometer. It is shown that the polyelectrolyte melts are non-Newtonian of shear-thinning fluid. The melt viscosity, die flow activation energy and the flow temperature are high even if the molecular weight is not high. The melting viscosity of PHGC is higher than that of PHGS at the same experimental conditions. By comparison with the case of PHGS the non-Newtonian index of PHGC is smaller, the flow activation energy and die flow temperature of PHGC are higher, which was caused by the difference in their molecular structure.

Multi-Religious Milieus

Tensta-Rinkeby and Skarholmen are two suburbs of Stockholm which are characterized of a multi-ethnic and multi-religious population created by immigration during the last decades. Many of those living in Tensta-Rinkeby and Skaholmen are Muslims, and others are Christians-native Protestants or Catholic and Orthodox immigrants. This article presents data from interviews with Muslim and Christian informants, leaders as well as lay persons, on how they look upon each other across religious borders. The information is classified and interpreted according to models used by scholars in theology of religion. Some informants give vague answers due to the fact that issues of assessing beliefs of others are seldom treated in their churches and mosques. Articulated opinions can be classified from a replacement to an acceptance-model with a bulk of proponents for a fulfillment-model in the middle. Finally the article discusses the importance of how religious actors teach and act in multi-religious milieus.

Religious Beliefs in Pre-lslamic Poetry

The subject of this study is how pre-Islamic poets viewed religious beliefs and how the Arabs dealt with such beliefs in the period that preceded the emergence of Islam, known as the/ahiliyya. The study discusses Arab religious beliefs and rites, which were filled with mythical elements such as idol worship, treating some animals as sacred, and worship of the sun, plants, certain inanimate objects and birds. It describes the various stages through which these beliefs passed, from sanctification of trees and caves, through the worship of the sun and the stars, to idol worship and more. The study then proceeds to inquire into the traces of mythology to be found in Arabic poetry. It shows how humans did not only inherit their forefathers＇ beliefs, but also their ideas, and explains how poets were able to embody reality by means of artistic symbols that reflected such elements of their lives as emotions and objective mental states. Subsequently the study discusses the sanctity which the Arabs ascribed to some animals, and which they worshipped in the hope of obtaining a blessing, maintaining an intimacy with the animal or averting evil. Many Arabs in those days believed in the sanctity of animals, the sun, the moon and Venus, thought that trees and other p｜ants possessed a spirit, and considered some animals to be deities with extraordinary powers, among them the viper, the crocodile, the bull, the gazelle and the goat. Finally, the study shows how pre-lslamic Arabic poetry can serve as a reliable document that reflects the society of the times, and how even the restricted amount of verse that has survived from those times can provide considerable information about mythical elements that go back to the remotest times.

A Spirit Philosophy Linking to Buddhism and Theology

Spiritual ontology,Buddhist epistemology,and theological axiology construct a spirit philosophy,where spiritual ontology sets up an ontological foundation,Buddhist epistemology provides a practical method,and theological axiology contributes a living ethics.While spirit philosophy covers spiritual ontology,Buddhist epistemology,and theological axiology,spirit philosophy links to Buddhism and theology and then introduces a popular philosophy toward the good.This is a mellow philosophical system.

Another Dimension of Ruth's Character:Sophisticated vs Noble

Ruth is a figure in the book of Ruth.She is described and taken as a noble and kind,obedient woman in a classical and theological understanding.But just a close reading may discover another aspect of Ruth's character-she is sophisticated as well according to Lacan's Mirror Stage Theory.

Reading Notes:The Red and the Black

The Red and the Black(Le Rouge et le Noir) was a novel by Stendhal, published in 1830. The title of the work had been trans-lated into English variously as Scarlet and Black, Red and Black, and The Red and the Black. The red and the black in works represent-ed the army and the black robe in church. It was the young French man normally through the two short cut for development. It was set in1830, which was after the French revolution and related a young man julien's attempts to rise above his plebeian birth through a combi-nation of talent, loving story, hard working, deception and hypocrisy, finally to find him betrayed by his own passions.

隐匿的非神——卡夫卡《城堡》诠释的神学之维

苏姗·桑塔格(Susan Sontag)在《反对阐析》一文中指出,卡夫卡的作品一直经受着社会寓言、心理分析寓言和宗教寓言等不下三拨阐释者的'大规模劫掠'(mass ravishment)的寓言'~①,《城堡》无疑是卡夫卡阐释者'劫掠'的重点对象。据学者统计,《城堡》已有的阐释不下七种~②。对于《城堡》及其作者而言,这或许不是坏事,恰如卡夫卡研究者库斯(Steve Coots)所言,一部作品之所以能成为'经典',原因就在于它可以从各个方面来进行诠释。

马克思主义、人文学和神学的交会与朝向未来的文化反思——“马克思主义、人文学研究与神学问题”国际研讨班会议综述

从“圣三”神学的视野看“梵二”会议之后的天主教社会训导

尽管《圣经》传统和早期教会思想中一直对社会正义问题,尤其是经济和社会秩序颇为关注,①教会兴办学校、医院、慈善机构也早已有之,但教会对社会问题公开发表自己的分析和看法,则是19世纪末以来的事.1891年教宗列奥十三世发表的《新事》通谕(Rerum Novarum)标志着天主教社会训导(Catholic Social Teaching)的开端.天主教社会训导可有广义和狭义之分.严格意义上,它是指自《新事》通谕以来教会发布的一系列训导文件,共有十三份.从广义上讲,社会训导还包括教宗或教会当局发布的其它训导文件,包括演讲、讲道、牧函等,亦可包括区域性主教会议或主教团根据当地的实际情况发表的牧函.②当然,最宽泛意义的天主教社会训导还可以包括《圣经》和教会传统中关于社会事务的观点.本文所论,仅限于严格意义上的天主教社会训导.

A modified rheological model of natural debris flows

The two coefficients of the linear dimensionless viscous-dispersive mixture model have been modified according to their rheological properties of different types of viscous debris flows based on the observation and experimental data of debris flows and their slurries in the field, and then a rheological model of hyperconcentrated debris flows has been derived. The modified coefficients are the exponent of A which is modified by the highly-viscous slurry medium, and the maximum density which is modified by the volume concentration of original debris flows with heterogenous grain size.
