The case study in this paper is on the Daur (as well as the Evenki, Buriat, and Bargu Mongols) in Hulun Buir, Northeast China. The aim of this research is to examine how shamanic rituals function as a conduit to actualize communications between the clan members and their shaman ancestors. Through examinations and observations of Daur and other Indigenous shamanic rituals in Northeast China, this paper argues that the human construction of the shamanic landscape brings humans, other-than-humans, and things together into social relations in shamanic ontologies. Inter-human metamorphosis is crucial to Indigenous self-conceptualization and identity. Through rituals, ancestor spirits are active actors involved in almost every aspect of modern human social life among these Indigenous peoples.

Abstract In this paper, transient analysis on heat transfer across the residential building roof having various materials like wood wool, phase change material and weathering tile is performed by numerical simulation technique. 2-dimensional roof model is created, checked for grid independency and validated with the experimental results. Three different roof structures are included in this study namely roof with (i). Concrete and weathering tile, (ii). Concrete, phase change material and weathering tile and (iii). Concrete, phase change material, wood wool and weathering tile. Roof type 3 restricts 13% of heat entering the room in comparison with roof having only concrete and weathering tile. Also the effect of various roof layers’ thickness in the roof type 3 is investigated and identified that the wood wool plays the major role in arresting the entry of heat in to the room. The average reduction of heat is about 10 % for an increase of a unit thickness of wood wool layer.

The selection of a rubber compound has a determining influence on the final characteristics of rubber-metal springs. Therefore, the correct selection of a rubber compound is a key factor for development of rubber-metal vibration isolation springs with required characteristics. The procedure for the selection of the rubber compound for vibration isolation of rubber-metal springs has been proposed, so that the rubber-metal elements have the necessary characteristics, especially in terms of deflection. The procedure is based on numerical simulation of spring deflection with Bergström-Boyce constitutive model in virtual experiment, with a goal to determine which parameters of the constitutive model will lead to spring required deflection. The procedure was verified by case study defined to select rubber compound for a rubber–metal spring used in railway engineering.
