Historical Developments

The aim of this review article is to present historical developments of mechanics of saturated granular soils in relation to the liquefaction phenomenon, as well as to analyze the present state of this subject in connection with practically important problems. The first part is an introduction to mechanics of liquefaction, in order to make this paper self-contained. Then, some basic empirical findings are described. In the third part, the development of theoretical approaches to liquefaction-related problems, such as cyclic loading compaction and pore pressure accumulation, or cyclic loading degradation of shearing resistance, is presented. The fourth part deals with the presentation of the methods applied for solving practically important problems and those that have not been solved satisfactorily. The last part of this paper presents some of the most important conclusions and suggestions regarding further research. There are 152 references cited in this review article, and a supplementary bibliography of 45 publications is also included.

The authors pursue three aims in this article. The first is to underscore critical praxis as an especially valuable approach to understanding and enabling teamwork. The second is to offer four dimensions of teamwork—vision, roles, processes, and relationships— as salient areas to interrogate using critical praxis. The third aim is to consider the implications and methods for teaching teamwork in the classroom context. In the process of doing so, the authors highlight limitations of prevailing theoretical approaches and note changes in their own practice of teaching and facilitating teamwork that have occurred through a commitment to critical praxis.

Ferula Asafoetida

Ferula is considered as the third largest genus of the family Apiaceae (Umbelliferae) which consists of 180-185 species. Asafoetida is defined as the oleo-resin gum extracted from the stem and rhizome of the Ferula asafetida plant. It is commonly called Hing or Devil's dung. It is a native species of Iran, Afghanistan and Pakistan. In Ayurveda, it is described as an analgesic agent and is mentioned in Charak Samhita. It carries a strong, tenacious and sulfurous odor. It is also used as a spice or as a condiment in various cookeries as a flavor like in curries, fresh vegetables, meat, pickles and pulses. Asafetida is distinguished as asafetida hing (hing) and asafetida (hingra). Traditionally, the plant is used to treat diseases like whooping cough, asthma, bronchitis, epilepsy, ulcer, stomachache, flatulence, bronchitis, antispasmodic, intestinal parasites, influenza and weak digestion. The main active constituents present in the Ferula asafetida plant are resins, gums and essential oils. From the reported studies it was found that the plant possesses various therapeutic and pharmacological properties like antioxidant, antimicrobial, antifungal, antiviral, antitumor, antimicrobial, antidiabetic, antispasmodic, hypertensive, hepatoprotective, neuroprotective and antiviral properties. In this review article, attempts have been made to describe the overall plant based on its modern and traditional view.

<p>In this review article, I have located the trajectory of development of the notion of literary archeology and the third relation of comparative literature, compared to influence and parallel ones, expounded by him in his newly published book in 2016, <i>The Third Notion of Comparative Literature: the Possibility of Literary Archeology</i>. My research shows that he has conceived this notion more than a decade ago and it’s the result of his lifetime endeavor on comparative literature in East Asia. I have employed almost all his monographs to trace the gradual formation of his ideas with two books as the focus, <i>The Third Notion of Comparative Literature: the Possibility of Literary Archeology</i> and <i>The Image of Willow: The Material Exchange and the Ancient Chinese and Japanese Literature</i>. The former aims to construct the theory of literary archeology as a renovated subject matter and the latter is composed of the case studies on willow which provide abundant evidence to illustrate his point. </p>

Excess Pore

This paper presents results from a series of piping tests carried out on a selected range of granular filters under static and cyclic loading conditions. The mechanical response of filters subjected to cyclic loading could be characterized in three distinct phases; namely, (I) pre-shakedown, (II) post-shakedown, and (III) post-critical (i.e., the occurrence of internal erosion). All the permanent geomechanical changes such, as erosion, permeability variations, and axial strain developments, took place during phases I and III, while the specimen response remained purely elastic during phase II. The post-critical occurrence of erosion incurred significant settlement that may not be tolerable for high-speed railway substructures. The analysis revealed that a cyclic load would induce excess pore-water pressure, which, in corroboration with steady seepage forces and agitation due to dynamic loading, could then cause internal erosion of fines from the specimens. The resulting excess pore pressure is a direct function of the axial strain due to cyclic densification, as well as the loading frequency and reduction in permeability. A model based on strain energy is proposed to quantify the excess pore-water pressure, and subsequently validated using current and existing test results from published studies.

Vladimir M. Alpatov’s new monograph addresses typological and theoretical issues related to the basic morphological units – word and parts of speech. It elaborates on his previous work on morphological theory, typology, and historiography of linguistic traditions. The monograph consists of an introduction and three chapters. The first two chapters, “The Problem of Word” and “The Problem of Parts of Speech” address the differences in theoretical approaches, evidence from independent linguistic traditions with particular reference to the Japanese indigenous linguistics, and data from psycholinguistic research. In the third chapter, “Anthropocentric and systemocentric approaches to language”, the author claims that the morphological logocentric and non-logocentric approaches are instances of the two more general approaches to language, respectively. In spite of some criticism, the reviewer concludes that the monograph makes much progress in understanding the structure and typology of the morphological elements, and similarities and difference among national linguistic traditions and grammatical theories.

The One

This introductory chapter begins with a brief discussion of the importance of the concept of power in political science. It then sets out the book's three main purposes. The first is to clarify and explicate Robert Dahl's concept of power. This is the concept of power most familiar to political scientists, the one most criticized. The second purpose is to examine twelve controversial issues in power analysis. The third is to describe and analyze the role of the concept of power in the international relations literature with particular reference to the three principal approaches—realism, neoliberalism, and constructivism. It is argued that a Dahlian perspective is potentially relevant to each of these theoretical approaches.
