Show moreA dry deposition sampling apparatus having at least one thin dry deposition plate with sample collection film is maintained on a support structure which is rotatable about a vertical axis and has a vane to maintain the sharp leading edge of the dry deposition plate(s) headed into the wind. Covers are positioned over the sample collection films automatically upon commencement of precipitation and are automatically moved to a position exposing the sample collection films to the atmosphere upon cessation of precipitation. The duration of exposure of the collection films to the atmosphere is timed, thus providing a dry deposition sampling apparatus which may be left unattended for long periods of time.

Show moreThis article examines the relationship between specific construction project characteristics and the degree and speed that the foremen are able to improvise in response to disruptive events on the jobsite. Specifically, characteristics such as the number of crew members working under the supervision of a foreman, the occupancy status of the project (i.e., occupied or unoccupied) during construction, the stage of completion of the project, and the levels of turbulence, time pressure, cooperation, collaboration, and organization, were examined. Using a multilevel regression modeling approach, an analysis of 244 disruptions reported by 50 foremen was conducted to determine whether the construction project characteristics could predict more or less improvisation and faster or slower improvisation by the foreman. The findings indicate that on construction projects that are rated by the foremen as more organized, the foremen can make more modest improvised decisions to resolve a disruption, but that on construction projects that were rated by the foremen as more collaborative (i.e., involved joint decision-making), a greater degree of improvisation was deployed. In addition, it was found that on sites that were rated by the foremen as more cooperative (i.e., involved greater willingness to help each other), the foremen required more time to improvise their decisions.

A process and apparatus for pulverization of natural and synthetic polymeric material by heating to a pre-melt or softening temperature below... Show moreA process and apparatus for pulverization of natural and synthetic polymeric material by heating to a pre-melt or softening temperature below its melting point, cooling and applying high normal and shear stresses sufficient to form fine powder, and fluidizing the powder in a gas stream preventing its agglomeration. The same process and apparatus is suitable for enhancement of reactivity of polymeric and solid monomeric material to form homopolymers, copolymers, and new polymeric materials.

A method for estimating the severity of generator unit outage and multi-terminal branch outage contingencies with respect to voltage collapse... Show moreA method for estimating the severity of generator unit outage and multi-terminal branch outage contingencies with respect to voltage collapse in large-scale electric power systems which includes the steps of estimating a post-contingency saddle-node bifurcation induced voltage collapse point of an electric power system following a set of generator unit outages and/or a set of branch outages and calculating a distance to collapse of said power system. The post-contingency voltage collapse point is determined by application of a nonlinear contingency screening method. Sponsorship: Illinois Institute of Technology United States Patent Show less

Show moreUsing tweets posted with #SOPA and #PIPA hashtags and directed at members of Congress, we identify six strategies constituents employ when using Twitter to lobby their elected officials. In contrast to earlier research, we found that constituents do use Twitter to try to engage their officials and not just as a “soapbox” to express their opinions. Show less

Show moreA process is provided wherein hemoglobin, a fragile material, is formulated into high hemoglobin content water-in-oil-in-water multiple emulsion while maintaining high yields and high oxygen exchange activity. A multiple emulsion of aqueous oxygen carrying material in oil in outer aqueous phase is suitable for provision of oxygen for oxygen transfer processes. A hemoglobin multiple emulsion in physiologically compatible oil in an outer aqueous saline solution is provided in sufficiently small droplet size to provide oxygen flow through blood vessels to desired body tissues or organs thereby providing a blood substitute.
