High intensity ultrasound can be used for the production of novel materials and provides an unusual route to known materials without bulk high temperatures, high pressures, or long reaction times. Several phenomena are responsible for sonochemistry and specifically the production or modification of nanomaterials during ultrasonic irradiation. The most notable effects are consequences of acousti...
Functional studies of resident microglia require molecular tools for their genetic manipulation. Here we show that microRNA-9-regulated lentiviral vectors can be used for the targeted genetic modification of resident microglia in the rodent brain. Using transgenic reporter mice, we demonstrate that murine microglia lack microRNA-9 activity, whereas most other cells in the brain express microRNA...
Dale Pearse School of Agricultural & Resource Economics, University of Western Australia A choice modeling approach was used to identify consumer preferences for various hypothetical forms of genetic modification in beer, using a sample from Western Australia. It was found that respondents were equally averse to first-generation modification in either plants or microorganisms but were willing t...
The Three Rs are the main principles used by Animal Ethics Committees in the governance of animal experimentation, but they appear not to cover some ethical issues that arise today. These include: a) claims that certain species should be exempted on principle from harmful research; b) increased emphasis on enhancing quality of life of research animals; c) research involving genetically modified...
Public opposition to genetic modification (GM) technology in the food domain is widespread (Frewer et al., 2013). In a survey of U.S. residents representative of the population on gender, age, and income, 64% opposed GM, and 71% of GM opponents (45% of the entire sample) were "absolutely" opposed-that is, they agreed that GM should be prohibited no matter the risks and benefits. "Absolutist" op...
Waste polymers are widely used in asphalt modification, especially, order to reduce their detrimental effect on the environment. This study discusses usability of waste expanded polystyrene (EPS) foam modification. In this respect, EPS foam, which produces both production and use stages, was mixed with bitumen by weight at ratios 2%, 4%, 6%, 8%, dry modification method employed. The penetration...
Unbleached kraft pulp fibers were modified with laccase and ferulic acid (FRC) to improve their physical strength properties in paper products. The optimal conditions of laccase-FRC modification were examined in terms of the physical properties of pulps. The effects of laccase-FRC modification on the carboxyl group content and surface lignin content of pulps were investigated. The surface morph...
Understanding plasma/complex surfaces interactions in NSTX with liquid lithium on thin porous molybdenum substrate for the divertor, additional PFC surfaces such as carbon tiles, and the presence of gases and impurities require integrated implementation and the interplay of detail various physical processes. These include simultaneous and multiple ion species penetration and mixing, scattering,...
One of the attack requirements for maximizing physical damage to digitally controlled infrastructures is the identification of a mapping between program variables in a compromised control system and physical parameters related to physical processes or physical equipment. A cyber-physical mapping is quite critical from the offensive perspective as physical parameters are affected via modificatio...
