Abstract: The present disclosure relates to compositions derived from bioreachable molecules, such as amino acids and/or steroids. In particular, the composition can be a monomer, a polymer, or a copolymer derived from an amino acid dimer. Such compositions can optionally include a functionalized steroid.

Abstract: A compound comprises a moiety selected from a cyclic dimer of a first and a second amino acid or a 2.5-diketopiperazine made from an amino acid. The moiety can be produced by fermentation. The compound further includes a polymerizable group. Additionally, the disclosure includes a method for preparing a resin comprises reacting the compound comprising the foregoing moiety and polymerizable group with a reagent.

Abstract: Deposition of carbene monolayers that excluded starting anions, such as iodide ions, has been achieved. Anions such as iodide are a typical contaminant in carbene hydrogen carbonate salts when synthesized using the state-of-the-art method. A method is described for eliminating substantially all starting anion (e.g., iodide) contamination from the monolayer. Air stable, purified carbenes precursors were used to deposit an intact monolayer on the surface of some industrially relevant metals. The monolayer's ability to protect these metals against, for example, oxidation has been demonstrated.

Abstract: In the field of monitoring communications systems, it is necessary for a monitoring system to be aware of an association of a Mobile Country Code (MCC), a Mobile Network Code (MNC) and an IP Address of a Gateway GPRS Support Node (GGSN) of a first network when a mobile terminal is roaming into a second network. Probes monitoring links with the second network generate transaction data. The transaction data is generated from messages communicated as part of a dialogue to establish a data “tunnel” between a Serving GPRS Support Node (SGSN) of the second network and the GGSN of the first network. The MCC, MNC and IP address data are extracted from the transaction data and used to update an address network name table.

Abstract: A vertical axis wind turbine wherein the blades of the rotor section of the wind turbine comprise at least sections wherein the blades have a non-linear configuration in the “z” axis. In a preferred embodiment, the blades of the rotor section have a linear trailing edge with a non-linear, and preferably helical, surface configuration. This particular design allows the blades to provide both a rotational force and a positive or negative lift component. Further, the blades define an open area in the center of the rotor section through which air flow can pass in order to create a vertical vortex of air. As such, a more efficient vertical axis wind turbine provided.
