Context. There are numerous extrasolar giant planets which orbit close to their central stars. These ‘hot-Jupiters’ probably formed in the outer, cooler regions of their protoplanetary disks, and migrated inward to ∼ 0.1 AU. Since these giant planets must have migrated through their inner systems at an early time, it is uncertain whether they could have formed or retained terrestrial planets. A...

In the core-accretion model, gas-giant planets form solid cores which then accrete gaseous envelopes. Tidal interactions with disk gas cause a core to undergo inward type-I migration in 10 to 10 years. Cores must form faster than this to survive. Giant planets clear a gap in the disk and undergo inward type-II migration in < 10 years if observed disk accretion rates apply to the disk as a whole...

Water migration changes the water distribution of loess and significantly affects engineering properties loess. However, because characteristics such as sensitivity special structure, it is still difficult to understand trend The objectives this study are investigate diffusion coefficient soil-water characteristic curve (SWCC) loess, focusing on effect temperature density, establish a mixed equ...

Giant planets found orbiting close to their central stars, the so-called ‘hot Jupiters’, are thought to have originally formed in the cooler outer regions of a protoplanetary disk and then to have migrated inward via tidal interactions with the nebula gas. We present the results of N–body simulations which examine the effect such gas giant planet migration has on the formation of terrestrial pl...

INTRODUCTION The effectiveness of low power lasers for incisional wound healing, because of conflicting results of previous research studies, is uncertain. Therefore, this study was carried out to evaluate low power laser effects on incisional wound healing. MATERIALS AND METHODS Incisional wound was produced on thirty-six mature male guinea pigs under general and local anesthesia. In half of...

Gas-giant planets, such as Jupiter, Saturn and massive exoplanets, were formed via the gas accretion onto solid cores each with a mass of roughly ten Earth masses. However, rapid radial migration due to disk-planet interaction prevents formation planetesimal accretion. Comparably core growth pebble requires very protoplanetary disks because most pebbles fall into central star. Although formatio...

Polymer nanocomposites incorporating metal or metal oxide nanoparticles have been developed to improve their characteristics (flexibility, gas barrier properties, antimicrobial or antioxidant properties, etc.). Among them silver nanoparticles are used because of their antimicrobial effect in many daily life materials, i.e. food packaging. However, there is not any reference to the migration of ...
