The mechanism of the ionized cluster beam deposition has been studied using Molecular Dynamics Simulation. The Embedded Atom Method(EAM) potential were used in the simulation. The impact of a Au95-cluster on Au(100) substrate was studied for the impact energies 0.15-10eV/atom. The dependency of the impact energy of cluster beam was observed. For the cluster energy impact of 10eV per atom, the defects on surface were created and the cluster embedded into substrate as an amorphous state. For the energy of 0.5eV per atom, the defect free homoepitaxial growth was observed and atomic scale nucleation was formated, which are in good agreement with experiment. Thus molecular dynamics simulation is very useful to study the mechanism of the ionized cluster beam deposition.

We have reviewed the potential impact of blockchain technology on the music industry by analyzing the views of academia and the industry experts. The music industry had rapid changes from the physical market to the digital market in the past decades. The consumers download and stream music online and mobile during the digital dominant market. While streaming music has been recently growing at a fast rate, fair distribution of revenue to the artists continues to be an issue. Some industry experts believe that the issue of fair distribution of revenue to the artist may be resolved using blockchain technology, while some are skeptical about the application or the duration of impact. The blockchain may enhance speedier payment using smart contracts, provide additional revenue and promote the music if excellent fan support is achieved. The positive impact on the music industry may only be possible if there are detailed consideration of the industry and careful understanding of the customers.

The main purpose of the study is to analyze the main aspects of the impact of military actions on the EU labor market. The research methodology includes modern theoretical methods and methods for analyzing the state of the EU labor market. The war in Ukraine changed not only the economy of one country, but the whole continent. The European Union has very sensitively felt the changes brought about by the military actions on the territory of Ukraine. Military actions on the territory of Ukraine are a destructive factor in the labor market. Today, the main task of economic recovery is to minimize the consequences of humanitarian problems and preserve human potential, which is an important source of business activity. Based on the results of the study, we have identified key aspects of the impact of military actions on the EU labor market.

This study investigates the impact of inflation rate fluctuations on economic growth in China, with a particular focus on potential non-linear characteristics. The global economic impact of the COVID-19 pandemic notably heightens the study's relevance. The research that the unidirectional causal relationship from inflation to economic growth in China first strengthens and then weakens over time. Furthermore, there is an inflation rate threshold effect on economic growth, identified at 2%. Below this threshold, inflation positively influences economic growth, whereas above it, the impact turns negative. This finding underscores the importance of balancing economic growth with inflation control in the formulation of monetary policy.

The paper begin by examining shipbuilding in the context of competitiveness, specification and cost-effectiveness before considering the impact of safety requirements in the its operations. The basis of the safety case approach is then given, and its application to shipbuilding is illustrated by an example based on the use of staging in ship construction. The key conclusion is that the safety case approach provides the management with a technique for treating potential hazards in shipbuilding so that their risks can be kept within an acceptable level.

At the time of facing strict environmental regulations, environmentally friendly dyeing technology is being highlighted due to the potential possibility of reducing environmental impact, so is the preparation process that uses a great deal of water and generates as much contamination. Enzyme technology has been regarded as an eco-friendly solution to industrial problems, saving water, chemicals and energy. (omitted)

Engineered nanoparticles are materials purposefully produced with at least one dimension between 1 and 100 nanometers. Nanotechnology has the potential to dramatically improve the effectiveness of a number of existing consumer and industrial products and could have a substantial impact on the development of new products in all sectors. However, nanoparticles is little known about what effect these properties may have on human health. This materials provide an overview of what is known about the potential hazards of engineered nanoparticles and measures that can be taken to minimize workplace exposures.

The registration of a pesticide for use in the gardens or a farmer's field requires assessment of the potential negative effects of that pesticide on human health. To anticipate how a pesticide might impact human health, laboratory animals such as mice and rats are exposed to varying dosages in their foods -from very minimal to extremely high levels. Toxicologists then evaluate the observable effect(s) of consuming known quantities of that specific pesticide on acute, subchronic, chronic, mutational, reproduction and neurological effects. Information gained from such test is evaluated by toxicologists and medical experts to determine potential human effects

Impact from water-borne debris during tsunami and flood events pose a potential threat to structures. Debris impact forces specified by current codes and standards are based on rigid body dynamics, leading to forces that are dependent on total debris mass. However, shipping containers and other debris are unlikely to be rigid compared to the walls, columns and other structures that they impact. The application of a simple one-dimensional model to obtain impact force magnitude and duration, based on acoustic wave propagation in a flexible projectile, is explored. The focus herein is on in-air impact. Based on small-scale experiments, the applicability of the model to predict actual impact forces is investigated. The tests show that the force and duration are reasonably well represented by the simple model, but they also show how actual impact differs from the ideal model. A more detailed three-dimensional finite element model is also developed to understand more clearly the physical phenomena involved in the experimental tests. The tests and the FE results reveal important characteristics of actual impact, knowledge of which can be used to guide larger scale experiments and detailed modeling. The one-dimensional model is extended to consider water-driven debris as well. When fluid is used to propel the 1-D model, an estimate of the 'added mass' effect is possible. In this extended model the debris impact force depends on the wave propagation in the two media, and the conditions under which the fluid increases the impact force are discussed.

In this paper, a real time diagnostic algorithm for estimating the impact location by loose parts is proposed. It is composed of two modules such as the alarm discrimination module (ADM) and the impact-location estimation module(IEM). First, ADM decides whether the detected signal that triggers the alarm is the impact signal by loose parts or the noise signal. Second, IEM by use of the arrival time method estimates the impact location of loose parts. In order to validate the application of this method, the test experiment with a mock-up (flat board and reactor) system is performed. The experimental results show the efficiency of this algorithm even under high level noise and potential application to Loose Part Monitoring System (LPMS) for improving diagnosis capability in nuclear power plants.
