Gymnostigmaeus akaminei n. gen., n. sp. (male). 12, leg I; 13, leg II; 14, leg III 15, leg IV. ; Etymology The new species is named in honor of Dr. H. Akamine (Faculty of Agriculture, University of the Ryukyus) who collected the present material. Biology Specimens of this species were collected together with the false spider mite Dolichotetranychus zoysiae Ehara (Tenuipalpidae) on the lawngrass Zoysia tenuifolia on Okinawa Island. Judging from the general habits of stigmaeids associated with phytophagous mites (e.g., Santos & Laing, 1985), G. akaminei n. sp. is presumed to be an effective predator of the eggs of D. zoysiae attacking Zoysia spp. Acknowledgements We are obliged to Dr. Q.H. Fan (Landcare Research, Auckland, New Zealand) for his help in literature and information, and to Dr. H. Akamine who collected the material used in this study.Published as part of Ehara, Shôzô & Ueckermann, E.

Electronic excitation spectra of molecules in solution calculated using the symmetry-adapted cluster-configuration interaction method in the polarizable continuum model with perturbative approach
No full textA perturbative approximation of the state specific polarizable continuum model (PCM) symmetry-adapted cluster-configuration interaction (SAC-CI) method is proposed for efficient calculations of the electronic excitations and absorption spectra of molecules in solutions. This first-order PCM SAC-CI method considers the solvent effects on the energies of excited states up to the first-order with using the zeroth-order wavefunctions. This method can avoid the costly iterative procedure of the self-consistent reaction field calculations. The first-order PCM SAC-CI calculations well reproduce the results obtained by the iterative method for various types of excitations of molecules in polar and nonpolar solvents. The first-order contribution is significant for the excitation energies. The results obtained by the zeroth-order PCM SAC-CI, which considers the fixed ground-state reaction field for the excited-state calculations, are deviated from the results by the iterative method about 0.1 eV, and the zeroth-order PCM SAC-CI cannot predict even the direction of solvent shifts in n-hexane for many cases. The first-order PCM SAC-CI is applied to studying the solvatochromisms of (2,2'-bipyridine)tetracarbonyltungsten [W(CO)(4)(bpy), bpy = 2,2'-bipyridine] and bis(pentacarbonyltungsten)pyrazine [(OC)(5)W(pyz)W(CO)(5), pyz = pyrazine]. The SAC-CI calculations reveal the detailed character of the excited states and the mechanisms of solvent shifts. The energies of metal to ligand charge transfer states are significantly sensitive to solvents. The first-order PCM SAC-CI well reproduces the observed absorption spectra of the tungsten carbonyl complexes in several solvents. (C) 2014 AIP Publishing LLC

No full textMass-rearing of Tetranychus truncatus ehara (Tetranychidae, Acarina) on waterlily
No full textA laboratory technique for mass-rearing the truncate spider mite, Tetranychus truncatus Ehara, is presented. This is an output of the project entitled Survey, biology and mass-rearing of common phytoseiid predators of ornamental mite pests, funded by the DA-BAR from July 2001 to June 2004. The technique is simple and convenient. It uses waterlily, Eichornia crassipes L., as oviposition substrate and feed, plastic bucket for holding the waterlily plants; rectangular plastic vats as moats; and tap water to keep the waterlily plants fresh. An average of 4,162 eggs, 1,414 active stages, 1,003 female adults and 200 male adults per leaf can be produced after two weeks of continuous rearing on waterlily

Inverse design of molecule-metal nanoparticle systems interacting with light for desired photophysical properties
No full textMolecules close to a metal nanoparticle (NP) have significantly different photophysical properties from those of the isolated one. In order to harness the potential of the molecule-NP system, appropriate design guidelines are required. Here, we propose an inverse design method of the optimal molecule-NP systems and incident electric field for desired photophysical properties. It is based on a gradient-based optimization search within the time-dependent quantum chemical description for the molecule and the continuum model for the metal NP. We designed the optimal molecule, relative molecule-NP spatial conformation, and incident electric field of a molecule-NP system to maximize the population transfer to the target electronic state of the molecule. The design results were presented and discussed. The present method is promising as the basis for designing molecule-NP systems and incident fields and accelerates discoveries of efficient molecular plasmonics systems
