The preparation of adamantine carbon or diamond has exercised the genius of philosophers from the very earliest times; but it was not until the middle of the last century (1772) that Lavoisier established the diamond's true nature—notwithstanding the simplicity of the experiments required to demonstrate the fact—and showed it to consist of pure carbon in a crystallised state. Since that time very many attempts have been made to prepare it artificially, but until the recent and now famous experiments of Mr J. B. Hannay there has not been the slightest approach towards the solution of this problem. Great obstacles stood in the way of success, the chief being the complete insolubility of carbon in all known liquids, coupled with its non-volatility and infusibility; while the subject was rendered even more difficult and obscure, by ignorance of the conditions under which the diamond is produced in nature, its peculiar crystalline form, together with extreme rarity, indicating a probable very slow formation, and rare natural existence of the conditions necessary for its formation.

This paper is a comparative study of two dramatic works of Henrik Ibsen’s “An Enemy of the people”, written in 1882, and Akbar Radi’s “The Savior in the Damp Morning” written in1986. It is an attempt at elaborating Althusser’s clarification of the term ‘Ideology’ as the disillusionment when the individualistic features are considered. This refers to the opposition which exists between how the ideological discourse functions and what an individual member of a society intents to establish. Rebelliousness is one of the significantly controversial characteristics of individualism which is regarded as its chaotic expression which can disrupt and rebuild the current ideology. In both Althusserism and Individualism, the subject holds the ideology that has been implicitly or explicitly defined due to the fact that the subject is exposed to as well as involved with it. Since the subject is the performer of certain acts and the conveyor of certain thoughts, the social relation which is constructed is determined according to the overall production or benefit for all those who are involved within the community. The ideology of social relation discredits the attempts of subjects at revealing self-governing and self-determining ideas which lead to disillusionment. This comparative study is, by and large, displaying the way two dramatists, who belong to completely distinct cultures and societies, presented the ideologies of their time and the true nature of invisible power discourses.

This review is devoted to the monograph by Jan Nedvěd “We do not decline our heads. The events of the year 1968 in Karlovy Vary”. The Karlovy Vary municipal museum coincided its publishing with the fiftieth anniversary of the Prague spring which, considering the way of the presentation, turned the book not only to scientific event but also to the social one. The book describes sociopolitical trends in the region before the year 1968, the development of the reformist movement, the invasion and advance of the armies of the Warsaw Pact countries, and finally the decline of the reformist mood and the beginning of the normalization. Working on his writing, the author deeply studied the materials of the local archive and gathered the unique selection of the photographs depicting the passage of the soviet army through the spa town and the protest actions of its inhabitants. In the meantime, Nedvěd takes undue freedom with scientific terms, and his selection of historiography raises questions. The author bases his research on the Czech papers and scarcely uses the books of Russian origin. He also did not study the subject of the participating of the GDR’s army in the operation Danube, although these troops were concentrated on the borders of Karlovy Vary region as well. Because of this decision, there are no materials from German archives or historiography in the monograph. In general, the work lacks the width of studying its subject, but it definitively accomplishes the task of depicting the Prague spring from the regional perspective.

In the present day scenario prime need of Ayurveda is practical applicability of Ayurvedic fundamental principles and research should be more focused on all aspects where scientific inputs should confirm Ayurveda’s principles and philosophy. In Ayurveda, Gunas are described as the way of presentation of action without which no Karma (action) can be possible. Ayurveda has provided significance to every Guna so that they become useful in clinical practice. Clinical practice or research is a continuous process including a series of events which need to be performed in a sequential manner. Though there are many factors on which accomplishment of treatment depends, among these Charaka has given prime importance to Paradi Gunas. In clinical practice, Guna which are to be with Bhishak are mainly the Paradi Gunas which can also be called as miscellaneous Gunas. As rightly quoted by Acarya Charaka, for getting success in the treatment Paradi Gunas are the best. The Sutra quotes "Sidhyupaya Chikitsayam" which means that Chikitsa i.e. Dhatusamya will be done mainly with the help of Paradi Gunas. Knowledge of Paradi Gunas are required to be present in pharmacists, physicians and Researchers. Acharya Charaka says that Chikitsa Siddhi i.e. successful management of disease is not possible without the knowledge of Paradi Gunas. Paradi Gunas play an important role in selection, adaption and manifestation of drug as per condition of the disease and the patient in particular Desha and Kala. The ultimate goal of any clinical activity is to contribute in the knowledge domain and to improve professional practice. Thus this literary review of Paradi Gunas serves to explore the subject of the clinical practice.

This article looks at Engels’s writings to show that his ideas about the role of labour in the evolution of human beings in a dialectical relationship between human beings and nature is a crucial starting point for understanding human society and is correct in its essentials. It is important for understanding that we developed as a species on the basis of social cooperation. The way human beings produce and reproduce themselves, the method of historical materialism, provides the basis for understanding how class and women’s oppression arose and how that can explain LGBTQ oppression. Although Engels’s analysis was once widely accepted by the socialist movement, it has mainly been ignored or opposed by academic researchers and others, including geographers, and more recently by Marxist feminists. However, anthropological research from the 1960s and 1970s as well as more recent anthropological and archaeological research provide overwhelming evidence for the validity of Engels’s argument that there were egalitarian, pre-class societies without women’s oppression. However, much remains to be explained about the transition to class societies. Engels’s analysis of the impact of industrial capitalism on gender roles shows how society shapes our behaviour. Engels’s method needs to be constantly reasserted against those who would argue that we are a competitive, aggressive species who require rules to suppress our true nature, and that social development is driven by ideas, not by changes in the way we produce and reproduce ourselves.

While the subject of women’s activity in historical and contemporary punk scenes has attracted significant attention, the presence of trans women in punk has received comparatively little research, in spite of their increasing visibility and long history in punk. This article examines the conditions for trans women’s entrance in punk and the challenges and opportunities that it offers for their self-assertion. By linking Michel Foucault’s notion of parrhesia with the way trans women in punk do their gender, an attempt is made at showing how the embodied experience of a trans woman making herself heard from the punk stage can serve as a site of ‘gender pluralism’.

AbstractThe past two decades have seen a dramatic renewal of interest in the subject of historical memory, its reproduction and transmission. But most studies have focused on the selection and construction of extant memories. This essay looks at missing memory as well. It seeks to broaden our understanding of memory by investigating the way in which historical memory significant to one historical tradition was slighted by another, even though the two overlapped both spatially and chronologically. It does this by an examination of how the memory of the Marathi-speaking peoples first neglected and then adopted the story of the Vijayanagara empire that once dominated southern India.

A texture pattern devised by the Japanese artist H Ouchi has attracted wide attention because of the striking appearance of relative motion it evokes. The illusion has been the subject of several recent empirical studies. A new account is presented, along with a simple experimental test, that attributes the illusion to a bias in the way that local motion signals generated at different locations on each element are combined to code element motion. The account is generalised to two spatial illusions, the Judd illusion and the Zöllner illusion (previously considered unrelated to the Ouchi illusion). The notion of integration bias is consistent with recent Bayesian approaches to visual coding, according to which the weight attached to each signal reflects its reliability and likelihood.
