3 Paragraph 4, lines 3 and 4, p. 2911: For the following sentence citing reference [60], units should be in μg/(m h); not in mg/(m h). On an area basis, caulking has the highest emission rate, 310 μg m h, among materials tested, followed by carpet pads (installed underneath carpets), 2.1 to 9.9 μg m h. Emission rates fell below 1 μg m h for other materials tested, which included solid and engin...

We consider a class of fractal subsets of Rd formed in a manner analogous to the construction of the Sierpinski carpet. We prove a uniform Harnack inequality for positive harmonic functions; study the heat equation, and obtain upper and lower bounds on the heat kernel which are, up to constants, the best possible; construct a locally isotropic diffusion X and determine its basic properties; and...

Introduction Stoddard Templeton denotes a group of Scottish carpet manufacturing companies, the formation of which can be traced to the mid-nineteenth century and the businesses James Templeton & Co and A F Stoddard & Co. Due to the growth, expansion, prominence and eventual decline of the Scottish carpet industry the history of these companies is intertwined. For 160 years, Stoddard Templeton ...

Youjiang Wang School a/Textile & Fiber Engineering Baik-Soon Cho and Abdul-Hamid Zureick School o/Civil Engineering Georgia Institute a/Technology Atlanta, GA 30332 The U.S. carPet industry consumes about 1.2 million tons of fibers annually and about 70% of the carpet produced is for replacement. The waste generated by the industry and from used carpet is estimated at about 2 million tons per y...

Purpose: To determine the relationship between refractive errors and ocular components values in carpet weavers Methods: Refractive errors and ocular components values were investigated in carpet weavers at Mashhad city in Iran. After selection of samples, the individuals who had ophthalmic and systemic disease effective on the refractive errors were excluded from the study. Refractive errors a...

As part of the National Human Exposure Assessment Survey (NHEXAS) in Maryland, we collected indoor air, carpet dust, exterior soil, and duplicate diet samples from a stratified random sample of 80 individuals to evaluate aggregate daily exposure, contributions of specific pathways of exposure, and temporal variation in exposure to chlorpyrifos. We collected samples from each participant in up t...

We introduce a class of conformal versions of the previously introduced quasi-conformal carpet cloak, and show how to construct such conformal cloaks for different cloak shapes. Our method provides exact refractive-index profiles in closed mathematical form for the usual carpet cloak as well as for other shapes. By analyzing their asymptotic behavior, we find that the performance of finite-size...

Results are presented that demonstrate the successful use of live bacteria as mechanical actuators in microfabricated fluid systems. The flow deposition of bacteria is used to create a motile bacterial carpet that can generate local fluid motion inside a microfabricated system. By tracking the motion of tracer particles, we demonstrate that the bacterial cells that comprise the carpet self-orga...

If a torsion-free hyperbolic group G has 1-dimensional boundary ∂∞G, then ∂∞G is a Menger curve or a Sierpinski carpet provided G does not split over a cyclic group. When ∂∞G is a Sierpinski carpet we show that G is a quasiconvex subgroup of a 3-dimensional hyperbolic Poincaré duality group. We also construct a “topologically rigid” hyperbolic group G: any homeomorphism of ∂∞G is induced by an ...
