Housing of weanling horses in cold loose housing systems is common in the Nordic countries, although its suitability as a winter environment has not been studied. This thesis aimed to study the effects of a cold loose housing environment on weanling horses. The loose housing system consisted of insulated halls with a deep-litter bed, entrance shelters and paddocks to which the group-housed hors...

In frozen regions, especially metro tunnel portal sections, which are vulnerable to an externally low-temperature atmosphere, would lead damage affecting traffic safety. To clarify how the air temperature field at sections varies with periodically changing atmospheric temperature, a site test was conducted on Metro Line 1 in Hohhot Inner Mongolia Autonomous Region, and basic heat transfer equat...

The accumulative roll bonding (ARB) as a severe plastic deformation (SPD) procedure aimed at enhancing the mechanical properties of metals and alloys. In the present study, a new slab method is proposed for estimating the forming stress field for cold extrusion of metals cross the alumina interlayer powder particles by accumulative roll bonding process. Plastic deformation behavior of the metal...

A wind corridor forest is defined as an urban for utilizing the functions of a that allow “cool and fresh air (cold air)” generated in forests at night to flow development areas. This study aims provide planning strategies implementing by analyzing current conditions Haengbok City (HBC region), Sejong, South Korea. The HBC region had many wind-generating (WGF), wind-spreading (WSF), wind-connec...
