The main objective of this paper is to highlight the research works being carried out on the hygrothermal behaviour of building materials and wall systems at the National Research Council (NRC) Canada. The paper depicts selected results obtained from parametric studies conducted on wood frame stucco walls commonly used in Canadian climatic conditions, using hygIRC, an advanced hygrothermal mode...

The investment casting of reactive Ti and TiAl alloys requires the use of selected ceramics in the face-coat layer to prevent the reaction between the cast metal and ceramic shell, avoiding the formation of a hard layer at the metallic components surface. This work aims to study the influence of ceramic shells composition in some of its characteristics such as flexural strength, friability and ...

The major pathways for transport of pyrethroids were determined in runoff studies conducted at a full-scale test facility in central California, USA. The 6 replicate house lots were typical of front lawns and house fronts of California residential developments and consisted of stucco walls, garage doors, driveways, and residential lawn irrigation sprinkler systems. Each of the 6 lots also inclu...

We discuss the gait generation and control architecture of a bioinspired climbing robot that presently climbs a variety of vertical surfaces, including carpet, cork and a growing range of stucco-like surfaces in the quasi-static regime. The initial version of the robot utilizes a collection of gaits (cyclic feed-forward motion patterns) to locomote over these surfaces, with each gait tuned for ...

For many decades, ventilated cavities in wall assemblies of buildings have been essential for creating moisture resilient constructions by allowing airflow within the air gap to promote drying. In addition that, cavity can enhance thermal performance building envelope, depending on change rate and outdoor conditions. Therefore, effective factors behind common with external cladding are specifie...

Abstract. In 2008, excavations at Herodium revealed magnificent secco wall paintings and stucco decorations adorning the central chamber top of royal theatre. The paintings, dated to first century B.C.E., have been preserved up a height 6 meters. However, shortly after discovery, salts weathering structural faults caused severe damages decorations. conservation process restore lasted almost dec...
