Legume symbiosis with rhizobia results in the formation of a specialized organ, the root nodule, where atmospheric dinitrogen is reduced to ammonia. In Lotus japonicus (Lotus), several genes involved in nodule development or nodule function have been defined using biochemistry, genetic approaches, and high-throughput transcriptomics. We have employed proteomics to further understand nodule deve...
White-rot fungi secret a large number of hydrolytic and oxidative enzymes for degradation of lignocellulosic material. The sequencing of the genome of the white-rot fungus Phanerochaete chrysosporium has facilitated the characterization of its complete extracellular proteome. P. chrysosporium was grown on liquid medium, containing glucose, cellulose or wood chips as the carbon source, and also ...
Features of the nanosecond discharge development in a non-uniform electric field are studied experimentally. High spatial resolution imaging showed that thin luminous tracks great length with cross-section few microns observed against background glow air and argon. It has been established detected adjacent to brightly white spots on electrodes or vicinity these spots, associated flight small pa...
The present work describes the preparation of a polyethylene film covered with protective layer zinc oxide nanoparticles (ZnO NPs). presence ZnO NPs on slide supplemented was confirmed by appearance white cloud-like spots. Various NP concentrations were examined for their impact optical and physical properties in terms inhibiting growth bacteria that can cause excessive irritation or intolerabl...
Most empirical work on color constancy is based on simple laboratory models of natural viewing conditions. These typically consist of spots seen against uniform backgrounds or computer simulations of flat surfaces seen under spatially uniform illumination. In this study measurements were made under more natural viewing conditions. Observers used a projection colorimeter to adjust the appearance...
The functional and cost advantages of Internet telephony are evident. By today's technical standards, however, Voice Over IP (VoIP) is still less secure than traditional telephony. At the same time, the hacker scene is constantly looking for new weak spots and developing ingenious methods of attack to gain access to confidential information and penetrate further into the network.
Bowtie aperture antennas are known to generate sub-diffraction limited optical spots in the visible and near-infrared frequencies, which can be applied to many areas. Regular bowtie apertures fabricated by FIB suffer from tapered sidewall and rounded corner, which degrade its optical enhancement and localization. In this work, a new fabrication method is demonstrated to manufacture bowtie apert...
