Although Ukrainian emigration to North America is not a new phenomenon, the dilemmas of memory and amnesia remain crucial in Ukrainian-American émigré fiction. The paper focuses on selected novels by Askold Melnyczuk (What is Told and Ambassador of the Dead) and analyzes how traumatic memories and family stories of the past shape the American lives of Ukrainian emigrants. The discussion of the selected Ukrainian-American émigré novels focuses on the dilemmas of remembering and forgetting in the construction of both Ukrainian and American narratives of the past. The voluntary amnesia of the Ame- rican-born Ukrainians in Melnyczuk’s novels confronts their parents’ dependence on the past and their inability to abandon it emotionally. Memories of ‘the old country’ make them, similarly to Ada Kruk, ambassadors of the dead. The expression becomes a metaphoric definition of those wrapped by their repressed, fragmentary and sometimes inaccessible memories. Crucial events of European history of the 20th century are inscribed and personalized in the older generation’s stories which their children are reluctant to hear. For them, their parents’ memories became a burden and a shame. Using the concept of transgenerational memory, the paper explores the challenges of postmemory, and eventually its failure.

Prior to implementing interventions, practitioners must first develop definitions of behavior that are objective. This chapter first provides a definition of behavior and provides three criteria for determining whether something is a behavior: it is demonstrated by a living organism, in interaction with the environment, and the interaction results in measurable change within the environment. Next, the chapter outlines how practitioners should develop operational definitions of behaviors of interest. Then, the chapter provides a description of the dead man’s test, a heuristic that practitioners often utilize when determining if something qualifies as a behavior suitable for intervention. Finally, the chapter describes the meaningful operant dimensions of behavior, such as frequency, duration, latency, and magnitude.

This article aims to act as a general literature review regarding the landscape, analyzing it through a synthesis of the main concepts and processes that have generated, and subsequently developed, the word “Landscape”. It is a versatile theme, because it has always been studied by various disciplines, through different theories, which sometimes even conflict with each other. Through the present text, we understand the importance and the unique value of the landscape, a value that has nowadays been transfigured by the strong industrialization and strong brand of man in the territory. Thus, the first part of the research is, to some extent, a reflection on current issues that are related to the landscape. It is also a tool for integration, including in the definition of “Landscape”, even those heavily humanized, exploited, degraded, abandoned, and residual; the so-called “Drosscape”, “Friche”, and “Terrain Vague”. The solution is not to negatively interpret these types of scenarios, but rather to enhance them as they are, filled with potential and creativity. This concept is achieved by means of an operation of recycling or reuse of waste, which is capable of germinating new life cycles within the “dead nature” of our increasingly cemented territories.

A boiling liquid, expanding vapor explosion (BLEVE) occurs when a pressure vessel containing a superheated liquid undergoes a catastrophic failure, resulting in a violent vaporization of the liquid. The exposure of a pressure vessel to a fire is a classic scenario that can result in a BLEVE. The thermomechanical exergy of a pressure vessel’s contents provides — by definition — an upper bound on the work that can be performed by the system during the explosion. By fixing the values of ambient pressure and temperature (i.e., the dead state), exergy can be interpreted as another thermodynamic property. This rigorous and unambiguous definition makes it ideal to estimate the maximum energy of explosions. The numerical value of exergy depends on the definition of the dead state. In this paper we examine the effect of different definitions for the dead state on the explosion energy value. We consider two applications of this method: the contribution of the vapor head-space to the explosive energy as a function of the fractional liquid fill of the vessel, and the effect of the vessel burst pressure.

When Andromache emerges from the inner chamber in Book 22, ascends the walls of Troy and looks out over the plain, she beholds a spectacle of ruthless brutality. She who has not been aware of the final combat, nor of the slaying of her husband, is suddenly confronted by the receding trail of utter defeat. Swift horses drag her husband's corpse into the distance, the cherished head disfigured as it is dragged, raking the dust of what was once their homeland. The violence of the scene is forcefully conveyed by one word in particular. The swift horses drag Hektor ⋯κηδ⋯στως (22.465)—without κ⋯δος without care, ‘sans soucier de, brutalement’. In itself the word ⋯κηδ⋯στως provides a definition of violence, one captured in Shakespeare's phrase ‘careless force’. Violence is, in its harsh brutality, specifically heedlessness, an absence of any form of care. When Achilles hurls the slain suppliant Lykaon into the river he utters the taunt, ‘the fish, ⋯κηδ⋯ες, will lick clean your wound's blood’ (21.122–3). The discarded corpse is denied funeral rites: in place of the care that the relations of the dead traditionally bestow in tending, washing, enshrouding, lamenting, and burying the dead, here the heedless creatures of nature, fleeting visitors, will attend to the corpse, ‘clean’ it, but utterly without care, completely oblivious to the oblivion they create by destroying. In Book 24 Achilles will describe the gods themselves as ⋯κηδ⋯ες (526).

This paper present a study focused on hot forward extrusion by upper bound method. In particular, hot forward extrusion of plates through square face dies under plane strain conditions. Slater defines the models used for large fractional reduction. Different models have been taken in account; they are dissimilar in relation to the dead metal zone (if covers or not the entire die face, partially or totally). Triangular rigid patterns of velocity discontinuities have been validated by analytical methods and a range of use for the selected configurations has been established. This methodology has been applied to other process with good results. Thus, the mechanical parameters analysed are fractional reduction, dead metal zone, length die and friction. Finally the calculation of the energy has been achieved by upper bound method. The results allow researching an optimisation of use of upper bound method in hot forward extrusion.

The creation of God is the belief that we will be safe by creating rituals and temples that are sacrificed by men who are afraid of the fury of nature. They also gave their hunting tools to the gods who created it and also established idolatry. Among the gods that were so, there is a dual ity of the small god. At first, the small deities were worshipped on the border of the village as a place where the dead ancestors lived as people. This is called the Guardian Goddess. The great deities are considered to be the deity of every deity shown in Thelly. The difference between the minor gods and the great gods does not appear to have been in the Sangam literature. However, it is a discretion to match the definition of today. In the society where the dead were usually the middle stones, the stones became worship. The study is the only small-sighted cult of the four temples that were built for the king, the deceased, the dead from the north, the life of the goddess, the king and the living.

This chapter focuses on the phenomenon of ‘commissions’ for the recovery of human remains that have proliferated across Timor-Leste. I argue that the commissions’ practices constitute forms of ‘nonstate governmentality’ (de Cesari 2010, 625) that take the government’s valorisation programme in unexpected directions. By working to exhume, identify, and categorise the dead the commissions are, to some extent, contributing to the state’s goal of dignifying martyrs. At the same time, they are potentially enlarging the definition of martyrdom beyond the state’s narrow interpretation. Ultimately, the commissions bring to light the nation’s painful history and remind the state of its responsibility to dignify all the nation’s martyrs.
