Nickel Base

Inconel 718, a precipitation hardenable nickel-base alloy, is a versatile high strength, weldable wrought alloy that is used in the gas turbine industry for components operated at temperatures up to about 1300°F. The nominal chemical composition is 0.6A1-0.9Ti-19.OCr-18.0Fe-3Mo-5.2(Cb + Ta)- 0.1C with the balance Ni (in weight percentage). The physical metallurgy of IN 718 has been the subject of a number of investigations and it is now established that hardening is due, primarily, to the formation of metastable, disc-shaped γ" an ordered body-centered tetragonal structure (DO2 2 type superlattice).

The Brain

In recent years, rapid technological developments in the field of neuroimaging have provided several new methods for revealing thoughts, actions and intentions based solely on the pattern of activity that is observed in the brain. In specialized centres, these methods are now being employed routinely to assess residual cognition, detect consciousness and even communicate with some behaviorally non-responsive patients who clinically appear to be comatose or in a vegetative state. In this article, we consider some of the ethical issues raised by these developments and the profound implications they have for clinical care, diagnosis, prognosis and medical-legal decision-making after severe brain injury.

Migration and Modernities recovers a comparative literary history of migration by bringing together scholars from the US and Europe to explore the connections between migrant experiences and the uneven emergence of modernity. The collection initiates transnational, transcultural and interdisciplinary conversations about migration in the eighteenth and nineteenth centuries, demonstrating how mobility unsettles the geographic boundaries, temporal periodization, and racial categories we often use to organize literary and historical study. Migrants are by definition liminal, and many have existed historically in the spaces between nations, regions or ethnicities. In exploring these spaces, Migration and Modernities also investigates the origins of current debates about belonging, rights, and citizenship. Its chapters traverse the globe, revealing the experiences — real or imagined — of eighteenth- and nineteenth-century migrants, from dispossessed Native Americans to soldiers in South America, Turkish refugees to Scottish settlers. They explore the aesthetic and rhetorical frameworks used to represent migrant experiences during a time when imperial expansion and technological developments made the fortunes of some migrants and made exiles out of others. These frameworks continue to influence the narratives we tell ourselves about migration today and were crucial in producing a distinctively modern subjectivity in which mobility and rootlessness have become normative.

Traditional research methods are inadequate to predict and explain consumer behavior accurately in some cases. Marketing discipline tries to benefit from new technological developments in order to make up the deficiency subjects’ competence and willingness to express how they feel when they face with stimulus in traditional data collection method has an effect on the success of the method. In traditional methods, subjects often cannot remember or know the correct answer, or even if they know the answer they will give answers that satisfy the researcher. The inadequacy in traditional techniques has driven the researchers to evaluate theconsumer response more accurately. It is observed that in recent years neuromarketing techniques began to be used extensively to measure consumer responses accurate in marketing field. Although neuromarketing is commonly used in marketing field, there are some questions about the efficiency of the method. This study emphasizes the efficiency on the general evaluation of neuromarketing techniques and criticism of it. The aim of this study is to indicate the historical development of application of neuro science on marketing and consumer behavior, and to establish the future of neuro science, its opportunities and threats.

The rapid pace of technological developments played a key role in the previous industrial revolutions. However, the fourth industrial revolution (Industry 4.0) and its embedded technology diffusion progress is expected to grow exponentially in terms of technical change and socioeconomic impact. Therefore, coping with such transformation require a holistic approach that encompasses innovative and sustainable system solutions and not just technological ones. In this article, we propose a framework that can facilitate the interaction between technological and social innovation to continuously come up with proactive, and hence timely, sustainable strategies. These strategies can leverage economic rewards, enrich society at large, and protect the environment. The new forthcoming opportunities that will be generated through the next industrial wave are gigantic at all levels. However, the readiness for such revolutionary conversion require coupling the forces of technological innovation and social innovation under the sustainability umbrella.
