Photonic bandgaps (PBGs) of two-dimensional (2D) triangular-lattice and square-lattice and decagonal quasi-periodic photonic crystals (PCs) have been analyzed, with a given scatterer radius and dielectric relative permittivity changing from 1 to 30 within air-cylinders-in-dielectric and dielectric-cylinders-in-air constructions.
Instead the architect, Dennis Wedlick, applied passive-house techniques, using heavy-duty insulation, virtually air-tight construction and a constant air filter system to heat and cool the home not with technology, but with purposeful design.
Ministers will then decide whether to approve the choice in the face of fierce opposition from environmental campaigners who fear both air and construction pollution.
Stan Kachnowski, a father of two young children from Tarrytown, wants clean air during construction of whatever is built or rebuilt or changed.
Huge industrial operations, including a steel mill, have been moved from Beijing to reduce air pollution; construction is forging ahead on a new railway line, airport terminal and too many world-class sports facilities to count.
The civil engineer today is concerned with an even larger transportation field e.g., traffic studies, design of systems for road, rail, and air, and construction including pavements, embankments, bridges, and tunnels.
Common features of Passive House design are thick walls and air tight construction, to minimise heat loss and infiltration respectively.
When all the hot air and construction dust settles by 2035, the total costs of the Coastal Branch are expected to exceed $1.75 billion.
As a Senator, he had urged the EPA to mount a "comprehensive" review of proposed air and construction permits for a BP refinery in Indiana.
Although the air base construction required the destruction of native villages, the American and Australian airfield engineers were assisted from 1 October by about 350 native laborers recruited by the NICA detachment.
These interventions could include behaviour change, communication about the risks of indoor air pollution, construction of improved cooking implements or increasing availability and lowering the cost of alternative cooking methods and/or cleaner fuels, one example being the solar-powered cookers utilized in Kenya, Zimbabwe, and Nepal, among other countries [ 32].
