Sojourner Cultural Adaptation Toward National Culture Change

National cultue is affecting sojourner’s daily routines in their host countries. Much of the focus surrounding national culture change has targeted the environment. A few systematic reviews have been carried out on the social impacts of national culture change among sojourners in a host country. The present article set out to analyze the impact of cultural adaptation’s practices toward national culture change. This review was used PRISMA Statement (Preferred Reporting Item for Systematic Review and Meta-Analysis) method and database search using Web of Sciences and Scopus. Based on this review, a total number of 45 articles were identified related to sojourners cultural adaptation towards national culture change. The review from previous studies suggest that sojourners had an experience faced cultural adaptation’s phase likes honeymoon phase, culture shock phase, adjustment phase and adaptation phase in order to adapt with host national culture.

Flutter in Started and Unstarted Transonic Linear Cascades: Simultaneous Measurements of Unsteady Loads and Shock Dynamics

In the present work, we report on an experimental study of bending/flap mode flutter of a blade within a linear cascade at transonic conditions. Driven by the motivation to understand the contribution of shock location/dynamics to flutter characteristics, we have performed simultaneous measurements of shock dynamics using high-speed shadowgraphy combined with unsteady load measurements on an oscillating blade within the cascade. The flutter characteristics in terms of energy transfer from the fluid to the blade and shock dynamics have been mapped out over a range of blade oscillation frequencies and static pressure ratios (SPRs) across the cascade, the latter being important as they decide the mean location of the passage shocks. SPR values studied include both conditions where the shock is within the passage (started cascade) and where the passage shock is pushed ahead of the leading edge of the blades (unstarted cascade). These measurements show characteristically different flutter behavior for an unstarted cascade compared with a started cascade, the former having received very little attention in the literature. While both these cases show small excitation levels at low reduced frequencies, the unstarted cascade case exhibits an additional relative narrow region of excitation at higher reduced frequencies with approximately an order of magnitude higher excitation energies. Comparison of the shock dynamics between the two excitation regimes shows significant differences in the phase of the leading edge shock in addition to changes in the suction side shock phase indicating that the two excitation regimes are of different origin.

Strategic Practices and Crisis Management

Important as it is, crisis has become the hallmark of the present era, making it necessary to confront, contain, and reduce its negative effects. As a science, crisis management is associated with responding to crises, and as an art, it is about making decisions under exceptional pressure in the absence of information. It also needs to follow methodical practices such as strategic thinking, strategic planning, and strategic management to ensure effectiveness. This chapter provides an overview of crisis management as a discipline, highlighting important aspects, such as the definition of crisis and related terms (accident, conflict, danger, and disaster), concepts, causes, and characteristics, and distinguishing between crisis management and management crisis in practice. The study also outlines a typical crisis life cycle and its phases (shock phase, regression phase, recognition phase, and adaptation phase). The research then moves to identifying crisis management strategies, defining preventive strategy technique, emphasizing the importance of effective strategic practices in crisis management, and minimizing their impact. The research concludes by proposing a model to increase the effectiveness of crisis management through effective strategic practices at the state level.

NUMERICAL MODELING OF THE BALLISTIC LIMIT IN THE HYDRODYNAMIC RAM

This paper presents the ballistic limit study for the water-filled aluminum tank. The objective was to determine the ballistic limit for the rear tank wall by using numerical method. Commercial software Altair Hyperworks 12.0 was employed for this study. The finite element coupled with smoothed particle hydrodynamics (SPH) was developed to model the perforation of fragment simulating projectile (FSP) towards water-filled tank. Verification of the results was done by comparing with the experiment results. The results showed that there were four main phase failures occurred, which were shock phase, drag phase, cavitation phase and exit phase. The ballistic limit for the rear wall was 479.27 m/s.

Correlation of measured neon soft X-ray pulses of the INTI plasma focus with the reflected shock phase at 12KV

The six-phase Lee Model Code is used to fit the computed current waveform to the measured waveform of the INTI Plasma Focus (PF;2.2 kJ at 12 kV), a T2 PF device, operated as a source of Neon soft X-ray (SXR) with optimum yield around 2.5 - 3 Torr of neon. The characteristic He-like and H-like neon line SXR pulse is measured using a pair of SXR detectors with selected filters that, by subtraction, have a photon energy window of 900 to 1550 eV covering the region of the characteristic neon SXR lines. The aim of this paper is to investigate the correlation between the time histories of the measured Neon soft X-ray pulse and the reflected shock phase of the computed current waveform which has been fitted to the measured current waveform. Results shows that the characteristic neon SXR measured at 3.17 J with a pulse duration of 249 ns starts typically after the radial inward shock phase and increases in magnitude few ns before the pinch phase. It tails unto the first anomalous resistance, and decays at the second anomalous resistance.
