With exposure to high-energy particle irradiation, structural metals develop a number of nanoscale defects, one which is the nano-sized He bubble. Formed throughout material, these bubbles can directly impair movement dislocations and dramatically alter mechanical performance. Propagating edge in face-centered cubic metals, driven under sufficient forces, are expected cut through bubbles, due h...

T his paper investigates the existence of possible spillover effects among four main asset markets namely foreign exchange, stock, gold, and housing markets in Iran from 2002:03 to 2015:06. For this purpose, we have exploited Sigma-Point Kalman Filter (SPKF) to extract the bubble component of assets prices in the aforementioned Markets. Then, in order to analyze the price bubbles spi...

Attachment of particles and droplets to bubbles—the latter being various fine sizes created by different techniques (as described in detail)—forms the basis flotation, a process which indeed was originated from mineral processing. Nevertheless, chemistry often plays significant role this area, order for separation be effective, as stressed. This (brief) review particularly discusses wastewater ...

The helium effects in Chinese developed CN-G01 beryllium are important issues for its use nuclear energy systems. In this work, the samples were irradiated with ions to fluences of 5.0 × 1016 ions/cm2 1.0 1018 at room temperature and investigated by techniques scanning electron microscopy (SEM), transmission (TEM) nano-indentation. It was found that irradiation induced hardening nano-hardness i...

The presence of bubbles in the markets and its formation has been regarded by economists and they have been looking to develop methods that can be recognized by using appropriate method for the formation of bubbles. In this paper, first, the formation of bubbles is tested using the new unit root test known as Phillips test (Generalized Sup ADF test) for 50 companies in the Tehran Stock Exchange...
