The improvement of human well-being and the urban environment in cities towns around world will always be at forefront our interests. After all, resilience to climate change is very important now. For example, residents’ can improved terms environmental aspects. opportunities for improving are, course, closely interconnected with other aspects, i.e., economic, technical social. One ways increas...

In order to reduce building energy consumption and make wall insulation materials meet fire protection requirements, the authors put forward a kind of saving model exterior under green nanomaterials. Mainly using PBECA calculation software. By setting up multi-component, multi-material method. The aggregate in light device modified by nanomaterials is simulated analyzed, agent area compared. ef...

The fundamental quantities of classical dynamics, such as position, velocity and acceleration, are expressed in terms of the Cartan tetrad, and the first Cartan structure equation is used to develop classical dynamics. The velocity is defined as the covariant exterior derivative of the position, and the acceleration as the exterior covariant derivative of the velocity. The resulting terms are a...

Mangroves are among the most well described and widely studied wetland communities in the world. The greatest threats to mangrove persistence are deforestation and other anthropogenic disturbances that can compromise habitat stability and resilience to sea-level rise. To persist, mangrove ecosystems must adjust to rising sea level by building vertically or become submerged. Mangroves may direct...

A vacuum system (20) includes an enclosure (22) having a vacuum-tight wall (26) and an internally threaded aperture (66) through the wall (26). A tip-off fitting (24) has a base (50) with a bore (52) therethrough. a hollow tube (62) fixed to the base (50) with a vacuum-tight seal. such that an interior (64) of the tube (62) is in communication with the bore (52) in the base (50). and an externa...

A prefabricated lightweight element was designed for a strip foundation that was used on site as the bases of two small residential buildings, in this case single-family houses; one was built with a double-brick exterior wall separated by mineral fiber insulation and the other was built with a wood-stud exterior wall with mineral fiber insulation. The element was placed on a stable surface unde...

The July 1992 Indoor Radon and Radon Decay Product Measurement Device Protocols, EPA 402-R-92-004 (EPA 1992) provides five measurement device location selection criteria that should be followed when placing a device within a room for measurement of the radon concentration. These criteria include: (1) a place where the device will not be disturbed and there is adequate room for the device, (2) a...
