Potential Uses Of Riverbank Filtration For Regulatory Compliance, Stig Regli

United States Environmental Protection Agency: Publications

RBF may have its most general application for systems seeking compliance with the LT2ESWTR. On August 11, 2003, the USEPA proposed the LT2ESWTR and included provisions by which RBF could be used as one of the compliance options for providing Cryptosporidium removal credits (USEPA, 2003).While the USEPA has previously recognized (through guidance implementation decisions) that RBF is a technology that can achieve pathogen removal, the LT2ESWTR is the first United States drinking-water regulation that specifically recognizes RBF as a compliance technology option.

Safety Performance Evaluation Of Michigan’S 4x5 Portable Sign Support, Ronald K. Faller, James C. Holloway, John R. Rohde, Dean L. Sicking

Mid-America Transportation Center: Final Reports and Technical Briefs

A wide variety of traffic controlling devices are used in work zones, some of which are not normally found on the roadside or in the traveled way outside of the work zones. These devices are used to enhance the safety of the work zones by controlling the traffic through these areas. Due to the placement of the traffic control devices, the devices themselves may be potentially hazardous to both workers and errant vehicles. The impact performance of many work-zone traffic control devices is mainly unknown and to date limited crash testing has been conducted, under the criteria of National Cooperative …

Performance Analysis Of Welch Products Recycled Rubber Spacer Block, Bob W. Bielenberg, Ronald K. Faller

Mid-America Transportation Center: Final Reports and Technical Briefs

The Midwest Roadside Safety Facility was contracted by Will Stein of the Iowa Department of Transportation to conduct dynamic bogie testing of a recyclable rubber guardrail spacer block manufactured by Welch Products, Inc. The scope of the work included the setup of both a standard, wood guardrail post blockout and the Welch Products recycled rubber blockout on a standard W150x13.5 steel post, as well as two component tests using a bogie vehicle. The bogie tests were conducted in accordance with previously accepted procedures to evaluate the performance of guardrail post blockouts made of non-standard materials.

A Performance Study Of Dynamic Zone Topology Routing Protocol, Mehran Abolhasan, Tadeusz A. Wysocki

Department of Electrical and Computer Engineering: Faculty Publications (to 2015)

In this paper we present a simulation study of a hybrid routing protocol we proposed in our previous work. Our hybrid routing strategy is called Dynamic Zone Topology Routing protocol (DZTR). This protocol has been designed to provide scalable routing in a Mobile Ad hoc Networking (MANET) environment. DZTR breaks the network into a number of zones by using a GPS. The topology of each zone is maintained proactively and the route to the nodes in other zones are determined reactively. DZTR proposes a number of different strategies to reduce routing overhead in large networks and reduce the single point …

Increasing Performance Of Sqrd Decoding For Lst Systems, Phillip Conder, Tadeusz A. Wysocki

Department of Electrical and Computer Engineering: Faculty Publications (to 2015)

A number of decoding schemes have been proposed for Layered Space-Time systems, such as the Ordered Successive Interference Cancellation and the Sorted QR Decomposition. We describe here a new addition to that group, increasing the performance of Layered Space-Time decoding by using the Sorted QR Decomposition technique to construct a list of constellations to be passed to a Maximum Likelihood decoder. This paper shows that signifcant performance improvement can be obtained for symmetric systems, where there is an equal number of transmit and receive antennas. It shows that the proposed scheme, has a roughly linear increase in complexity compared to …

On The Effect Of Adjacent Sector Multiple Access Interference On Space Time Spreading Systems, Peter Vial, Ibrahim Raad, Tadeusz A. Wysocki

Department of Electrical and Computer Engineering: Faculty Publications (to 2015)

Space Time Spreading systems are proposed as a method to enhance communications between the Base Station (BS) and Mobile Station (MS) by using multiple transmit antennas at the Base Station. This provides a form of transmit diversity when there are more than one transmitting antennas. Space Time Spreading systems have been shown to be efficient in their use of the limited number of orthogonal spreading sequences and to provide a diversity gain, which in the case of two transmitter antennas at the BS and one receiving antenna at the MS, is of order two. The paper looks at the effect …

Diet And Physical Performance, Scott J. Montain, Andrew J. Young

United States Army: Publications

This paper provides a historical summary of military nutrition research into the role of diet for sustaining soldier physical performance. Studies of underfeeding document that physical performance is preserved during several days of underfeeding provided sufficient carbohydrate and minerals are consumed to minimize the diuresis associated with semi-starvation diets and serial intake of carbohydrate is available to support metabolism during prolonged work. The Military Recommended Dietary Allowances, AR 40-25, currently recommends that when restricted rations are required, that the ration contain at least 1100–1500 kcal, 50–70 g of protein, and a minimum of 100 g of carbohydrate on a daily …

United States Army Corps of Engineers, Omaha District

In 1989, the U.S. Army Corps of Engineers (Corps) initiated consultation with the U.S. Fish and Wildlife Service (Service) regarding operation of the Missouri River Main Stem Reservoir System (See Figure 1). This consultation was conducted under the provisions of section 7 of the Endangered Species Act (ESA), which requires Federal agencies to consult with the Service when the agency’s proposed actions may affect the status of species listed as endangered or threatened. For the Missouri River operations by the Corps, the species covered in the 1989 consultation were the endangered Interior least tern (Sterna antillarum), threatened Northern …

Effects Of Age-Related Gait Changes On The Biomechanics Of Slips And Falls, Thurman E. Lockheart, Jeffrey C. Woldstad, James L. Smith

Department of Industrial and Management Systems Engineering: Faculty Publications

A laboratory study was conducted to examine gait changes associated with aging and the effect of these changes on initiation of slips and frequency of falls utilizing newly defined biomechanical parameters of slips and falls. Twenty-eight participants from two age groups (young and old) walked around a circular track at a comfortable pace wearing a safety harness. A slippery floor surface was placed on the walking track over the force plate at random time intervals without the participants’ awareness. Synchronized kinetic and kinematic measurements were obtained on both slippery and non-slippery walking surfaces. The results indicated that older participants’ horizontal …

Scale-Up Of The Fermentation And Purification Of The Recombinant Heavy Chain Fragment C Of Botulinum Neurotoxin Serotype F, Expressed In Pichia Pastoris, Scott K. Johnson, Wenhui Zhang, Leonard A. Smith, Karen J. Hywood-Potter, S. Todd Swanson, Vicki L. Schlegel, Michael M. Meagher

Michael Meagher Publications

A recombinant heavy chain fragment C of botulinum neurotoxin serotype F (BoNTF(Hc)) has been expressed in Pichia pastoris for use as an antigen in a proposed human vaccine. P. pastoris cells were grown using glycerol batch, glycerol fed-batch, and methanol fedbatch methods to achieve high cell densities. The total cellular protein recovered after homogenization was 72 mg/g of cell paste. BoNTF(Hc) was purified from soluble Pichia cell lysate employing ion-exchange chromatographic (IEC) and hydrophobic interaction chromatographic (HIC) methods developed at the bench scale using 10–100mL columns. The process was performed at the pilot scale using 1–4 L columns for evaluation …

The Economic Impacts Of Various Public-Policy Scenarios For Methane Recovery On Dairy Farms, Richard Stowell, Chris G. Henry

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

The feasibility of anaerobic digesters for dairy and swine operations in Nebraska was evaluated using EPA’s Ag Star software program Farmworks 2.0 (1997) and local values for farm energy costs, mainly electricity. Four incentive programs were considered that would subsidize anaerobic digestion. Installation of a digester system is a significant investment that is currently very difficult to justify economically to Nebraska producers based upon consideration of readily quantifiable income and expenses, regardless of farm size. Larger dairy operations looking to invest in this technology would benefit most from a tax credit and/or subsidized electricity sales, policies that relate directly to …
