Among th. available options for renewable energy integration in existing power system, wind power is being considered as one of th. suited options for future electrical power generation. Th. major constraint of wind power generating system （WPgS） is th.t it does not provide inertial support because of power electronic converters between th. grid and th. WPgS to facilitate frequency stabilization. Th. proposed control strategy suggests a substantial contribution to system inertia in terms of sh.rt-term active power support in a two area restructured power system. Th. control sch.me uses fuzzy logic based design and takes frequency deviation as input to provide quick active power support, wh.ch.balances th. drop in frequency and tie-line power during transient conditions. Th.s paper presents a compreh.nsive study of th. wind power impact with.increasing wind power penetration on frequency stabilization in restructured power system scenario. Variation of load conditions are also analyzed in simulation studies for th. same power system model with.th. proposed control sch.me. Simula- tion results advocates th. justification of control sch.me over oth.r sch.mes.

Ch.orfenapyr, an insecticidal pyrrole, was applied to concrete arenas at concentrations of 1. 1, 0.825, 0.55, and 0.275 g of active ingredient [AI]/m^2. Adult Tribolium castaneum （h.rbst）, th. red flour beetle, were exposed for 2, 4, or 8 h.at each.concentration, th.n removed and h.ld eith.r with.or with.ut food （wh.at flour） for 7 days. Survival was assessed wh.n th. beetles were removed fi＇om th. exposure arenas and daily during th. post- exposure period. In th. presence of food, survival was h.gh.regardless of concentration and th. day on wh.ch.post-treatment survival was assessed, but survival did decrease as th. exposure period increased from 4 to 8 h. Wh.n th. beetles were not given food after exposure, survival at each.concentration and exposure period declined during th. 1-week post- exposure assessments. Th.s pattern of decrease could be described by linear and non-linear equations. Results sh.w th. presence of food material greatly compromised effectiveness of th. insecticide, and emph.size th. importance of cleaning and sanitation in conjunction with.insecticide treatments.

Boreh.le and surface samples from th. Arch.an Tanzania Craton were analysed for apatite fission track(AFT) and(U-Th./h. data with.th. aim of deciph.ring cooling h.stories of th. basement rocks. Fission track dates from boreh.le and outcrop samples are Carboniferous-Permian(345± 33.3 Ma to271±31.7 Ma) wh.reas(U-Th./h. dates are Carboniferous-Triassic(336±45.8 Ma to 213±29 Ma) for outcrop grains and are consistently younger th.n corresponding AFT dates. Single grain(U-Th./h. dates from th. boreh.le are likely to be flawed by excessive h.lium implantation due to th.ir very low effective uranium contents, radiation damage and grain sizes. All AFT and(U-Th./h. dates are significantly younger th.n th. stratigraph.c ages of th.ir h.st rocks, implying th.t th. samples h.ve experienced Ph.nerozoic elevated paleo-temperatures. Considerations of th. data indicate removal of up to 9 km overburden since th. *** modelling reveals a protracted rapid cooling event commencing during th. early Carboniferous(ca. 350 Ma) at rates of 46 m/Ma ending in th. Triassic(ca. 220 Ma). Th. model also suggests minor cooling during th. Cretaceous of th. samples to surface temperatures. Th. suggested later cooling event remains to be tested. Th. major cooling ph.se during th. Carboniferous is interpreted to be associated with.compressional tectonics during th. Variscan Orogeny sensu far field induced stresses. Coeval sedimentation in th. Karoo basins in th. region suggests th.t most of th. cooling of cratonic rocks during th. Carboniferous was associated with.denudation.

Identification of all genes involved in th. ph.toch.ome （ph.）-medieted responses of plants to th.ir ligh. environment is an important goal in providing an overall understanding of ligh.-regulated growth.end development. Th.s article h.gh.igh.s end integrates th. central findings of two recent compreh.nsive studies in Arabidopsis th.t h.ve identified th. genome-wide set of ph.-reguleted genes th.t respond rapidly to red-ligh. signals upon first exposure of dark-grown seedlings, and h.ve tested th. functional relevance to normal seedling ph.tomorph.genesis of an Initial subset of th.se genes. Th. data：（a） reveal considerable complexity in th. ch.nneling of th. ligh. signals th.ough.th. different ph.-femily members （ph.A to ph.E） to responsive genes; （b） identify a diversity of transcription-factor-encoding genes as major early, if not primary, targets of ph. signaling, end, th.refore, as potentially important regulators in th. transcriptional-network h.erarch.; and （c） identify auxin-related genes as th. dominant class among rapidly-regulated, h.rmone-related genes. h.wever, reverse-genetic functional profiling of a selected subset of th.se genes reveals th.t only a limited fraction are necessary for optimal ph.-induced seedling deetioletion.

A series of field trials were conducted in a commercial food storage facility to evaluate exposure of stored-product insects to aerosol formulations of synergized pyreth.ins and th. insect growth.regulator meth.prene. Wh.n adults of Tribolium castaneum （h.rbst）, th. red flour beetle, and Tribolium confusum （Jacqueline DuVal）, th. confused flour beetle were exposed with.and with.ut a food source to synergized pyreth.in aerosol, th.re was no difference in adult mortality with.respect to availability of food at eith.r 7 or 14 days after exposure （P≥0.05）. h.wever, mortality was lower in T. confusum （40.4% and 79.3% with.flour at 7 and 14 days, 38.9% and 84.8% with.ut flour at 7 and 14 days） compared to T. castaneum （96.5% and 99.8% with.flour at 7 and 14 days, 91.0% and 98.7% with.ut flour at 7 and 14 days）. Few late-stage larvae and pupae of eith.r species exposed to th. pyreth.in aerosol emerged as adults. In tests with.meth.prene aerosol, adult emergence of exposed 3- and 4-week-old larvae of T. confusum was less th.n 2%. Only 0.3% of 4-week-old larvae of T. castaneum exposed in open and obstructed areas emerged as adults. Emergence of adults from eggs of Plodia interpunctella （h.bner）, th. Indianmeal moth. embedded in culture media and exposed to th. meth.prene aerosol was 13.2%±3.5%. Results sh.w th.t th. aerosols evaluated in our study could give effective control of some of th. major storedproduct insect pests in commercial food storage facilities, and may offer an alternative to fumigation.

A growing number of genes responsible for reproductive incompatibilities between species （barrier loci） exh.bit th. signals of positive selection. h.wever, th. possibility th.t genes experiencing positive selection diverge early in speciation and commonly cause reproductive incompatibilities h.s not been systematically investigated on a genome-wide scale. h.re, I outline a research.program for studying th. genetic basis of speciation in broadcast spawning marine invertebrates th.t uses a priori genome-wide information on a large, unbiased sample of genes tested for positive selection. A targeted sequence capture approach.is proposed th.t scores single-nucleotide polymorph.sms （SNPs） in widely separated species populations at an early stage of allopatric divergence. Th. targeted capture of both.coding and non-coding sequences enables SNPs to be ch.racterized at known locations across th. genome and at genes with.known selective or neutral h.stories. Th. neutral coding and non-coding SNPs provide robust background distributions for identifying Fsm-outliers with.n genes th.t can, in principle, identify specific mutations experiencing diversifying selection. If natural h.bridization occurs between species, th. neutral coding and noncoding SNPs can provide a neutral admixture model for genomic clines analyses aimed at finding genes exh.biting strong blocks to introgression. Strongylocentrotid sea urch.ns are used as a model system to outline th. approach.but it can be used for any group th.t h.s a complete reference genome available.

Let ΡΥ（X） be th. semigroup of all partial transformations on X, Υ（X） and Ι（X） be th. subsemigroups of ΡΥ（X） of all full transformations on X and of all injective partial transformations on X, respectively. given a non-empty subset Y of X, let ΡΥ（X, Y） = {α∈ ΡΥ（X）： Xα Y}, Υ（X, Y） = ΡΥ（X, Y） ∩Υ（X） and Ι（X, Y） = ΡΥ（X, Y） ∩ Ι（X）. In 2008, Sanwong and Sommanee described th. largest regular subsemigroup and determined green＇s relations of Υ（X,Y）. In th.s paper, we present analogous results for both. Υ（X, Y） and Ι（X, Y）. For a finite set X with.｜x｜≥ 3, th. ranks of ΡΥ（X） = ΡΥ（X, X）, Υ（X） = Υ（X, X） and.Ι（X） = Ι（X, X） are well known to be 4, 3 and 3, respectively. In th.s paper, we also compute th. ranks of ΡΥ（X,Y）, Υ（X, Y） and Ι（X, Y） for any proper non-empty subset Y of X.

Relationsh.p between magnesium ammonium ph.sph.te （MAP） crystal properties and th. filtration ability of h.llow fiber membrane （h.M） were investigated. Ph.sph.rus recovery process by crystallization h.s a problem th.t it produces a large amount of fine crystals. So improvement of th. crystallization process by combining with.filtration was discussed. MAP crystals were obtained by batch.reaction crystallization and th. filtration ch.racteristics were investigated. Th. filtration was evaluated by th. specific filtration resistance （ac） on h.M. Filtered slurry was prepared with.each.suspension density and crystal size distribution. Th. solution was filtered at constant pressure of 0.02 MPa and th. filtration time on each.filtrated volume was recorded. As a result, αc decreases exponentially with.suspension density increasing from 0.25 g/L to 0.5 g/L and αc decreases moderately with.suspension density increasing from 0.5 g/L to 1.5 g/L. ac of large crystals decreases exponentially at less suspension density th.n αc of small crystals does. Also, αc increases as th. ratio of th. fractured crystals increases.
