The Polypodium vulgare complex (Polypodiaceae) comprises a well-studied group of fern taxa whose members are cryptically differentiated morphologically and have generated a confusing and highly reticulate species cluster. Once considered a single species spanning much of northern Eurasia and North America, P. vulgare has been segregated into 17 diploid and polyploid taxa as a result of cytotaxo...

Many marine animals track odor plumes to their source. Although studies of plume-tracking behavior have been performed in unidirectional flow, benthic animals such as crustaceans live in coastal habitats characterized by waves. We compared signal encounters by odor-plume-tracking stomatopods (mantis shrimp) in wave-affected and unidirectional flow in a flume. Stomatopods are small enough that w...

A procedural modification of the AOAC Official Method for extracting light filth from ground oregano and ground marjoram was tested in an intralaboratory study. The modified method specifies isopropanol defatting, 975.49A(a), rather than chloroform-isopropanol defatting, 975.49A(b), followed by direct flotation as directed in AOAC Official Method, 975.49B(b). The modified method provided compar...

The present work represents potential bio-sorbents: Tilia cordata (little leaf linden) and Foeniculum vulgare (fennel). copper removal was operated in batch procedure. Adsorbent mass, ion concentration, pH, time, temperature considerations were inspected. highly beneficial provisions for adsorption are 10 mg /L as preliminary 0.2 g mass pH 5.5 5.23 vulgare. Adsorption statistics follow the Lang...

The world species of Zambion Kasparyan (Hymenoptera: Ichneumonidae: Tryphoninae) are revised including re-descriptions of Zambion monodon Kasparyan and Zambion hirtum Delobel. Five new species are described: Zambion kasparyanisp. n., Zambion rogerisp. n., Zambion eileenaesp. n., Zambion wahlisp. n. andZambion broadisp. n. A key to species is provided. The genus is endemic to Africa (Angola to K...

The Ontong Java-Manihiki-Hikurangi plateau (OJMHP) is considered to have originated from a starting mantle plume, and have been rifted apart by two spreading ridges. However, the ages of these spreading ridges and their possible interactions with the presumed mantle plume are unclear. The Manihiki-Hikurangi plateau has been rifted apart by the Osbourn Trough which formed the southwestern Pacifi...

We shed light on the fundamental form of the Peregrine soliton as well as on its frequency chirping property by virtue of a pertinent cubic-quintic nonlinear Schrödinger equation. An exact generic Peregrine soliton solution is obtained via a simple gauge transformation, which unifies the recently-most-studied fundamental rogue-wave species. We discover that this type of Peregrine soliton, viabl...

foeniculum vulgare (fennel) has been widely used in traditional medicine for treatment of variousdiseases including pediatric colic. this study was designed to assess the antinociceptive effects of aqueousextract of f. vulgare on visceral pain and possible involvement of opioidergic, serotonergic, adrenergic andhistaminergic systems. the results of this study showed that aqueous extract of f. v...
