The first use of geosynthetic reinforced soil walls for integral bridge abutment construction in North America occurred on the Greenville Southern Connector (I-185) toll road in 1999. A second bridge with a longer span and higher loads was constructed in 2000 for the same project. Each of these four bridge abutment walls were constructed over 20 ft. (6 m) high using modular concrete block wall (MCBW) facing units and geosynthetic reinforcement with a silty fine to medium sand backfill around vertically driven steel H-pile foundation elements. While the piles were designed to carry all the vertical live and dead bridge loads, the lateral loads due to momentum, braking, and thermal movement would be transferred through the integrally cast-in-place concrete abutment to the piles laterally loading the wall facing elements, located just 3 ft. (1 m) behind the MCBW facing being restrained by the geosynthetic reinforcement within the abutment wall. This paper is a 16-year update on the service life performance of these MSE integral abutment walls based on visual observations and deformed shape measurement of the wall facing blocks. Results of survey monitoring of the wall facing deformations are presented and discussed. The wall face performance indirectly evaluates the distribution of stresses into the wall system structural components. This evaluation is done within the context of the prevailing 1998 FHWA (ASD) engineering analysis and design procedures for MSE walls utilized in 1999, including distribution of the pile induced lateral loads. A brief description of the geosynthetic installation details around the piles is presented to understand the applied analytical methods. © ASCE.

The increasing awareness of the energy-environment nexus is compelling the development of technologies that reduce environmental impacts during energy production as well as energy consumption during environmental remediation. Countries spend billions in pollution cleanup projects, and new technologies with low energy and chemical consumption are needed for sustainable remediation practice. This perspective review provides a comprehensive summary on the mechanisms of the new bioelectrochemical system (BES) platform technology for efficient and low cost remediation, including petroleum hydrocarbons, chlorinated solvents, perchlorate, azo dyes, and metals, and it also discusses the potential new uses of BES approach for some emerging contaminants remediation, such as CO2 in air and nutrients and micropollutants in water. The unique feature of BES for environmental remediation is the use of electrodes as non-exhaustible electron acceptors, or even donors, for contaminant degradation, which requires minimum energy or chemicals but instead produces sustainable energy for monitoring and other onsite uses. BES provides both oxidation (anode) and reduction (cathode) reactions that integrate microbial-electro-chemical removal mechanisms, so complex contaminants with different characteristics can be removed. We believe the BES platform carries great potential for sustainable remediation and hope this perspective provides background and insights for future research and development. © 2015 Elsevier Inc.

Purpose To analyze the current practice patterns of non-arthroplasty treatment of knee osteoarthritis (OA) and to assess the impact of the American Academy of Orthopaedic Surgeons clinical practice guidelines on the management of OA of the knee, particularly as they relate to the use of arthroscopic treatment. Methods The United Healthcare Database (2004-2009, 11 million patients, 216 million records) was used for the study and was searched using Boolean language for International Classification of Diseases, Ninth Edition, Clinical Modification and Current Procedural Terminology, fourth revision codes. A reference group was defined as patients treated with knee arthroplasty in 2009 and diagnosed with knee OA in the same record. Clinical practice patterns in the 5 years preceding arthroplasty were analyzed in this group. Results The reference group consisted of 12,806 patients undergoing total knee arthroplasty in 2009 with a documented diagnosis of OA at the time of surgery, with prior nonoperative treatment strategies analyzed during the preceding 5 years (2004-2009); 10.0% of patients were prescribed physical therapy specific to OA, 2.6% received an unloader brace, 0.52% underwent acupuncture, 43.5% were administered intra-articular corticosteroids, and 15.4% received viscosupplementation injections. During the 5 years before arthroplasty, 2,505 patients (19.6%) underwent arthroscopy and debridement/lavage, 35% of whom did not have a diagnosis code for mechanical pathology. Within 1 year of knee arthroplasty, 2,028 of the 2,505 knee arthroscopies (80.9%) were performed. Conclusions The findings show that significant gaps do exist between the evidence-based American Academy of Orthopaedic Surgeons recommendations and actual practice patterns in the United States between 2004 and 2009.

Coxiella burnetii is the etiological agent of Q fever, a disease that is often spread to humans via inhalational exposure to the bacteria from contaminated agricultural sources. Outbreaks have been observed all over the world with larger foci generating interest in vaccination programs, most notably in Australia and the Netherlands. Importantly, exposure rates among military personnel deployed to the Middle East can be relatively high as measured by seroconversion to C. burnetii-specific antibodies. Q fever has been of interest to the biodefense community over the years due to its low infectious dose and environmental stability. Recent advances in cell-free growth and genetics of C. burnetii also make this organism easier to culture and manipulate. While there is a vaccine that is licensed for use in Australia, the combination of biodefense- and public health-related issues associated with Q fever warrant the development of a safer and more effective vaccine against this disease. © 2014 Ruiz and Wolfe.

A sediment microbial fuel cell (MFC) was tested to determine if electron transfer from the anaerobic zone of contaminated sediments to the overlying aerobic water could facilitate an enhanced and aerobic equivalent degradation of total petroleum hydrocarbons (TPH). Results indicate that voltages as high as 190mV (2162mW/m 3) were achieved in a sediment MFC with an anode buried in sediments containing TPH concentrations at approximately 16,000mgkg -1. Additionally, after approximately 66 days, the TPH degradation rates were 2% and 24% in the open-circuit control sediment MFC and active sediment MFC, respectively. Therefore, it appears that applying MFC technology to contaminated sediments enhances natural biodegradation by nearly 12 fold. Additionally, a novel sediment MFC was designed to provide a cost-effective method of passive oxidation or indirect aerobic degradation of contaminants in an otherwise anaerobic environment. In addition, the use of a wicking air cathode in this study maintained dissolved oxygen concentrations 1-2mgl -1 higher than submerged cathodes, demonstrating that this technology can be applied to environments with either aerobic or anaerobic overlying water and an anaerobic matrix, such as shallow lagoon, ponds, and marshes, and groundwater. © 2012 Elsevier B.V.

This Letter concerns two-photon excitation of 2,5-diphenyloxazole (PPO) upon illumination from a pulsed 532 nm solid state laser, with an average power of 30 mW, and a repetition rate of 20 MHz. A very agreeable emission spectrum position and shape has been achieved for PPO receiving one- and two-photon excitation, which suggests that the same excited state is involved for both excitation modes. Also, a perfect quadratic dependence of laser power in the emission intensity function has been recorded. We tested the application of a small solid state green laser to two-photon induced time-resolved fluorescence, revealing the emission anisotropy of PPO to be considerably higher for two-photon than for one-photon excitation. © 2010 Elsevier B.V.

Pete Manca; Chairman, CEO, and President of Egenera, spent a short time discussing the recent acquisition of Fort Technologies. Here's a short summary of that discussion. Egenera has taken many steps away from its beginnings as one of the first blade computer suppliers. One of the most important moves was to free its PAN Manager from its very tight integration with Egenera's own hardware and allow it to be deployed on systems offered by many different suppliers. In Egenera's words: "Egenera maintains over 50 partnerships with the world’s leading technology companies including Citrix, Dell, EMC, Fujitsu Technology Solutions, HP, Intel, Microsoft, Novell, Oracle, Red Hat, SAP and VMware. Egenera flagship product, PAN Manager, is certified on major blades platforms, including IBM, HP, Fujitsu, NEC and Dell." I walked away with the belief that the acquisition made sense for Egenera, its customers and its partners.

Egenera, the Massachusetts-based cloud management company, announced this morning that it will acquire Dublin, Ireland-based Fort Technologies, which makes cloud lifecycle software. As you can deduce from the above, the name of the game is enterprise-class cloud services. Egenera wants Fort's management capabilities for its PAN Cloud Director software, its EMEA -- that's Europe, Middle East, Africa -- customer base and its existing partner agreements. Fort's personnel will be lumped into Egenera's Cloud Products group; the company's chief executive, Gerry Murray, will head Egenera's EMEA operations. Fort's claim to fame is making it easier for the IT organization to design and deploy IT services -- they like to say that it's "a simple drag and drop exercise." According to its datasheet, the company is Linux-specific. Meanwhile, Egenera focuses more on the back end, developing software that makes it easier for the enterprise to turn infrastructure elements (servers, physical and virtual; storage; switches; applications; operating systems) into elastic cloud resources. The unified company and platform will address private and public cloud deployments for enterprise data centers, service providers and governments.
