Free indole-3-acetic acid levels were measured by gas chromatography-mass spectrometry in three ultra-tall 'slender' Pisum sativum L. lines differing in gibberellin content. Measurements were made for apices and stem elongation zones of light-grown plants and values were compared with wild-type, dwarf, and nana phenotypes in which internode length is genetically regulated, purportedly via the g...

Selaginella iridescens (Selaginellaceae), a new species of spikemoss from Hainan Island, China, is described based on morphological and molecular evidence. The morphologically resembles S. pseudotamariscina Vietnam which was recently recognized segregated tamariscina pulvinata. Some characters iridescens, including the iridescent leaves long arista (0.35–1.20 mm long), widely membranaceous marg...

The flagellum in many predatory flagellates is equipped with rigid hairs, which reverse the direction of thrust to generate a feeding current. We have discovered novel mechanism for generation hairy flagella, fundamentally different from slender body theory governing smooth flagella. show that generated at crests flagellar wave, thanks key role hydrodynamic interactions among effectively functi...

Astyanax cocibolca, a small filter-feeding species is a new characid species endemic to Lake Nicaragua. It is distinguished from the syntopic Astyanax aeneus by its high gill raker count, slender body, upturned snout, long maxillary bones, conical outer premaxillary teeth, lower number of scales above lateral line, more intense black lateral band, smaller size, and trophic niche partitioning. A...

Unstable cutting due to chatter vibrations is one of the most important problems during metal cutting operations. Chatter can be a limitation for productivity and surface quality in turning operations, especially when long and slender tools and parts are involved. In this study, an analytical stability method for turning process is presented. The model takes the cutting geometry into considerat...

A new species of caligid copepod, Lepeophtheirus simplex sp. n., parasitic on bullseye puffer, Sphoeroides annulatus (Jenyns) in Sinaloa, Mexico is described. The new species is distinguished from its congeners by the possession of (1) a maxillule with simple dentiform process; (2) a sternal furca with sharply pointed, curved tines; (3) a 2-segmented exopod of leg 3 with simple, slender spine o...

A 83-year-old woman with chronic gastrointestinal problems developed retinal vein thrombosis. Laboratory tests revealed an erythrocyte sedimentation rate of 45, renal dysfunction (GFR 25 mL/min), and mild anemia (hemoglobin 10 G/dL) with normal white cells and platelets. 2-microglobulin was elevated at 8.06 mg/L. A plasma cell dyscrasia was suspected and immunoglobulin testing showed monoclonal...

Nematodes are vermiform animals of long and thin body and slender at the two extremities. They have great economic importance because many are plant parasitic and very difficult to erradicate once established in the soil. A prerequisite to combating their agricultural impact is correct identification of species. We present a preliminary study for constructing a computational procedure for nemat...

The status and distribution of Idionyx Hagen, 1867 (Odonata: Corduliidae), of the Western Ghats, India, is updated and a new species Idionyx gomantakensis is described and illustrated based on male and female specimens from Kulem (= Collem), Goa, India. This new species can be differentiated from other species of Idionyx by long and slender cerci and epiproct, absence of teeth in the basal half...

We consider a class of potential problems on a periodic half-space for the modeling of electrified oil films, which are used in the development of novel switchable liquid optical devices (diffraction gratings). A boundary integral formulation which reduces the problem to the study of the oil-air interface alone is derived and solved in a highly efficient manner using the Nyström method. The oil...
