ADAM metalloprotease-disintegrins share a common modular structure of functional domains for proteolytic, cell adhesion, and signaling interactions. The metalloprotease domain of oughly half of the known ADAMs contain an intact consensus metzincin catalytic site, and they are thus thought to function as active metalloproteases. The types of interactions mediated by ADAMs are expressly conspicu...

Experiments were performed to determine the effect of community composition on system function (bacterial production) in arctic Alaska. In this system bacterial production is controlled by: community, temperature, nutrients, and carbon source. Lake inlet and outlet communities in these experiments were different in composition, based on PCR-DGGE fingerprinting of 16S rDNA. For both communities,...

This paper outlines the current state of the virtual prototyping program using ADAMS under development at GreyPilgrim Incorporated. This program is being developed in order to provide analysis in the mechanical design of cable driven hyperredundant flexible manipulators, referred to as EMMAs (Easily Manipulated Mechanical Arms). A diagram of a typical EMMA manipulator can be seen in Figure 1 be...

Sorption of uranium (VI) from aqueous solution onto powdered corn cob has been carried out using batch and fixed-bed technique. The experimental results in batch technique were fitted well with pseudo second-order kinetics model. In the fixed bed technique, Thomas and Bohart-Adams models were evaluated by linear regression analysis for U(VI) uptake in different flow rates, bed heights and initi...

need to prepare an environmental impact statement. Document Access and Management System (ADAMS), which provides text and image files of NRC's public documents. The ADAMS accession numbers for the documents related to this notice are as follows: Document ADAMS accession No. If you do not have access to ADAMS or if there are problems in accessing the documents located in ADAMS, contact the NRC's...

The present paper deals with the analysis and homogenization of a lubrication problem, via two-scale convergence. We study in particular the Elrod-Adams problem with highly oscillating roughness effects. 0 Statement of the problem Cylindrical thin film bearings are commonly used for load support of rotating machinery. Fluid film bearings also introduce viscous damping that aids in reducing the ...

Sorption kinetics The model assumes that three chemical phases of PCBs are in equilibrium. As EPA points out, this is a common modeling assumption, but I believe it is only reasonable within a stationary sediment bed, and not within the water column during sediment resuspension. Following Wu and Gschwend (1986), and focusing only on sorption and desorption among two phases (sorbed PCB with conc...

For any 1-reduced simplicial set K we define a canonical, coassociative coproduct on ΩC(K), the cobar construction applied to the normalized, integral chains on K, such that any canonical quasi-isomorphism of chain algebras from ΩC(K) to the normalized, integral chains on GK, the loop group of K, is a coalgebra map up to strong homotopy. Our proof relies on the operadic description of the categ...
