Escherichia coli O157:H7 is a significant human pathogen that has mostly foodborne and waterborne modes of transmission. Although capable of infecting several hosts, the main source of this bacterium is cattle. In humans, it mainly causes hemorrhagic colitis, bloody diarrhea and hemolytic uremic syndrome. This bacterial pathogen is fairly resistant to various stresses and can survive for significant periods of time in the environment outside of a host. Some of the factors impacting its survival include the indigenous microbial communities, its ability to attach to food contact surfaces and form biofilms, temperature and dehydration. To address the public health concerns associated with this pathogen, several disinfection and sanitization procedures and technologies have been developed in recent years. Synergies between different procedures have been evaluated as well. This review addresses recent developments regarding the survival and disinfection of E. coli O157:H7. © 2011 Landes Bioscience.

In a series of recent papers, Prof. Olariu and his co-workers have promoted the vision of vehicular clouds (VCs), a nontrivial extension, along several dimensions, of conventional cloud computing. In a VC, underutilized vehicular resources including computing power, storage, and Internet connectivity can be shared between drivers or rented out over the Internet to various customers. Clearly, if the VC concept is to see a wide adoption and to have significant societal impact, security and privacy issues need to be addressed. The main contribution of this work is to identify and analyze a number of security challenges and potential privacy threats in VCs. Although security issues have received attention in cloud computing and vehicular networks, we identify security challenges that are specific to VCs, e.g., challenges of authentication of high-mobility vehicles, scalability and single interface, tangled identities and locations, and the complexity of establishing trust relationships among multiple players caused by intermittent short-range communications. Additionally, we provide a security scheme that addresses several of the challenges discussed. © 2000-2011 IEEE. Source

This study reports on the results of a census of design trends of 300 state government portal and agency homepages within the United States. The results can be used by government web designers to aid web design decisions and improve usability, researchers wishing to compare the findings with other populations, and future researchers who wish to study changes in homepage design over time. The study has found a limited number of design elements were common in state portal and state agency homepages. In addition, it found that state portal and agency homepage design is lacking in terms of design principles (such as screen length), navigation principles (such as in use of search boxes, site indexes, and site maps), providing of communication options, and inclusion of multimedia and Web 2.0 technologies.

Platinum Metals Review

The electrochemical behaviour of platinum as a regenerator electrode during the photolysis of buffered aqueous solutions of ferrocyanide ([Fe(CN) 6] 4-) as a source of hydrated electrons for hydrogen production was investigated. Optimum conditions for the heterogeneous reduction of ferricyanide ([Fe(CN) 6] 3-) in aqueous suspensions of semiconductor nanoparticles were determined, and hydrogen generation was explored in both homogeneous and heterogeneous aqueous systems. Experiments took place in a three-electrode cell. The results indicated that the Pt gauze electrode gave adequate and reproducible photoelectrochemical performance during the photolysis of aqueous solutions of [Fe(CN) 6] 4- in 0.2 M pH 6 phosphate buffer. The results provide evidence for the important role of Pt in photolysis studies that aim towards harvesting solar energy. © 2012 Johnson Matthey. Source

The past decade has witnessed a phenomenal market penetration of wireless communications and a steady increase in the number of mobile users. Unlike wired networks, where communication links are inherently stable, in wireless networks, the lifetime of a link is a random variable whose probability distribution depends on mobility, transmission range, and various impairments of radio communications. Because of the very dynamic nature of Vehicular Ad hoc NETworks (VANETs) and the short transmission range mandated by the Federal Communications Commission (FCC), individual communication links come into existence and vanish unpredictably, making the task of establishing and maintaining routing paths between fast-moving vehicles very challenging. The main contribution of this work is to investigate the probability distribution of the lifetime of individual links in a VANET under the combined assumptions of a realistic radio transmission model and a realistic probability distribution model of intervehicle headway distance. Our analytical results were validated and confirmed by extensive simulation. © 2011 IEEE. Source
