The meander line employing periodic ground structure (MLEPGS) was fabricated on GaAs substrate for application to miniaturization of RF components on MMIC, and its RF characteristics were thoroughly investigated. The MLEPGS with a length of λ/8 showed loss less than 0.72 dB up to 20GHz, which was low enough for application to RF passive components. The MLEPGS showed much higher propagation constant β and effective permittivity εeff than conventional meander line. Concretely, the MLEPGS with T of 20 μm showed μ of 1.08-20.85 rad/mm and εeff of 2703-2479 from 1 to 20GHz, while the conventional meander line showed β of 0.18-3.36 rad/mm and εeff of 74.2-64.7 in the same frequency range. According to the result, the size of the λ/4 transmission line employing the MLEPGS was 0.151mm2, which was 3.5% of the size of the transmission line employing conventional meander line.

Mesorhizobium loti MAFF303099 has a functional type III secretory system (T3SS) involved in the nodulation process on Lotus tenuis and Lotus japonicus. Four putative M. loti T3SS effectors (Mlr6358, Mlr6331, Mlr6361, and Mlr6316) have been previously described, and it has been demonstrated that the N-terminal regions of Mlr6361 and Mlr6358 mediate the secretion via a T3SS. Here, we demonstrate the capacity of Mlr6316 and Mlr6331 N-terminal regions to direct the secretion of a translational fusion to a reporter peptide through T3SS. By using single, double, and triple mutants, we demonstrated the positive and negative participation of some of these proteins in the determination of competitiveness on Lotus spp. Low competitiveness values correlated with low nodulation efficiency for a mutant deficient in three of the putative M. loti effectors. Our data suggest that the net effect of M. loti T3SS function on symbiotic process with Lotus results from a balance between positive and negative effects. © 2012 Federation of European Microbiological Societies.

Solar power is becoming an alternative for industrial plants to consider as the technology has improved and been refined. An average solar Photo Voltaic system saves thousands of tons of carbon dioxide emissions annually, equivalent to removing hundreds of cars from the road. Solar power is one of the few distributed generation options for businesses to take advantage of that does not emit any pollutants into the atmosphere and can directly reduce a company's carbon footprint. Solar radiation, which is nearly constant outside the Earth's atmosphere, varies with changing atmospheric conditions (clouds and dust) and the changing position of the Earth relative to the sun. ALZA Corporation's manufacturing facility installed a 1-megawatt (MW) photovoltaic solar energy system working with SPG Solar. SPF-1000 enables the manufacturing plant to produce one-third of the power the plant requires on a high-power-demand summer day. The price of energy and government incentives are a big part of the economics for solar projects that need to be considered. Source
