چکیده
Abstract In late 2016, the Interstellar Boundary Explorer (IBEX) observed an enhancement of hydrogen energetic neutral atom (ENA) flux in ?20° south from nose direction. This was a consequence abrupt increase solar wind (SW) dynamic pressure at 1 au 2014. subsequent years, increased 4.3 keV ENAs higher latitudes filling heliosheath, lower energies, and Ribbon flux. We observe that rapid SW occurs every cycle (SC) beginning regular situ measurements ecliptic plane. The pulse happens about 4.7 yr each SC, it is during maximum phase activity, repeats with period ?10.2 yr. These repeating pulses can cause periodic SC variations ENA production heliosheath. follow McComas et al. results for relation between to investigate increases their consequences heliosphere. Our study time delay (pressure au) (ENA enhancement) show IBEX 2009–2011 remnants happened 23.

Purpose: Physiological changes during pregnancy impose numerous changes on the respiratory system that can affect the health of both mother and fetus. Regarding the importance of the normal breathing in the health of mother and fetus, this study aimed to investigate the effect of breathing exercise on breathing pattern of pregnant women. Methods: The study population was pregnant women...
متن کاملThe Heliosphere in Time
Because of the dynamic nature of the interstellar medium, the Sun should have encountered a variety of different interstellar environments in its lifetime. As the solar wind interacts with the surrounding interstellar medium to form a heliosphere, different helio-sphere shapes, sizes, and particle contents result from the different environments. Some of the large possible interstellar parameter...
متن کاملBoundary Conditions of the Heliosphere
Radiative transfer equilibrium models of nearby interstellar matter (ISM) are required to determine the boundary conditions of the heliosphere from astronomical observations of nearby stars. These models are also constrained by data on the ISM inside of the solar system, including pickup ion, anomalous cosmic rays, and in situ He data. The two best ISM models give semi-empirical filtration fact...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
