Species of the genus Dercetina Gressitt & Kimoto, 1963 in Taiwan are revised. Dercetina azumai Gressitt and Kimoto, 1966, Dercetina itoi Kimoto, 1969, and Dercetina shirozui Kimoto, 1969 are redescribed. Dercetina chinensis (Weise, 1889), Dercetina taiwana (Chûjô, 1938), and Dercetina unifasciata (Allard, 1889) are removed from synonymy with Dercetina flavocincta (Hope, 1831). Dercetina flavoci...

HE importance of day length as a determining factor in the time of T floral initiation in plants was first reported by GARNER and ALLARD (1920). Since then numerous investigations have been conducted on this phenomenon, and many plants have been classified into short-day, long-day and day-neutral types on the basis of their response to photoperiod. All known varieties of teosinte belong to the ...

We present two results characterizing minimizers of the Chan-Esedoḡlu LTV functional F (u) ≡ ∫ |∇u|dx + λ ∫ |u − f |dx; u, f : R → R. If we restrict to u = χΣ and f = χΩ, Σ,Ω ∈ R, the LTV functional reduces to E(Σ) = Per(Σ) + λ|Σ M Ω|. We show that there is a minimizer Σ such that its boundary ∂Σ lies between the union of all balls of radius nλ contained in Ω and the corresponding union of n λ ...

The purpose of this study is to investigate the role density and pile height on sound absorption coefficient in Double Base Persian (DBP) rug possibility prediction acoustic behavior DBP using mathematical model. For aim, first step, three double base samples were produced at different densities (2, 4, 6 warp yarn/cm) was measured with Impedance tube two thicknesses (15 & 13 mm) effect. Mor...

Observations of Cepheids in the Large Magellanic Cloud, made over last several decades, allow us to search for evolutionary period changes. None of the Cepheid from our sample of 378 stars stopped pulsating. Also none of them showed a large period change which could indicate mode switching. However for Cepheids with log P > 0.9 we found significant period changes, positive as well as negative. ...

To predict noise in enclosure containing treated vibrating panels, porous layer effect has to be taken into account. This study propose an analytical model of the effects of a porous layer on a vibrating plate by separating the acoustical and vibratory behaviours. This paper deals with acoustic coupling by means of surface impedance derived by a one-dimensional model using ”Biot-Allard” theory....

BACKGROUND The scalloped hammerhead shark, Sphyrna lewini, is a large endangered predator with a circumglobal distribution, observed in the open ocean but linked ontogenetically to coastal embayments for parturition and juvenile development. A previous survey of maternal (mtDNA) markers demonstrated strong genetic partitioning overall (global Φ(ST) = 0.749) and significant population separation...

By antimicrobial and cytotoxic-guided fractionation, a bioactive norquinone-methide triterpene, 15 alpha-hydroxypristimerin, was isolated from a South American medicinal plant, Maytenus scutioides. Its structure was determined on the basis of spectroscopic evidence. Successful chemical transformation of pristimerin to netzahualcoyene indicates that the 15-hydroxy compounds seems to be a possibl...
