formerly the turkmenian stone loach was the only member of the genus metaschistura based on osteological characters. but recently, it is placed in the genus paraschistura based on mtdna coi data. to provide a detailed description of the osteological characteristics of paraschistura cristata (berg 1898), ten specimens of p. cristata were collected from the hari river basin in iran and their oste...

1 Morphology with or without Affixes The last few years have seen the emergence of several clearly articulated alternative approaches to morphology. One such approach rests on the notion that only stems of the so-called lexical categories (N, V, A) are morpheme "pieces" in the traditional sense—connections between (bundles of) meaning (features) and (bundles of) sound (features). What look like...

osteological features are important to study the taxonomy and phylogenetic relationship of fishes. since there is no information is available about osteological features of squalius orientalis , therefore this study was aimed to provide a detailed description of the osteological features of this species from the urmia lake basin of iran and comparing it with population of s. orientalis from the...

nitrogen containing bisphosphonate (n-bp) therapy is used extensively to treat osteoporosis and osteolytic bone lesions. recently, a special form of osteonecrosis limited to the maxillofacial skeleton has been discovered especially within those patients who are receiving either long-term n-bp therapy alone and/or associated with invasive dental procedure. bisphosphonates accumulate almost exclu...

Die computergestützte Distribution von Dienstleistungen in der Reisebranche begann mit dem Anwachsen des Reiseverkehrs in der Luft. Sitzplätze in Flugzeugen sind leicht verderbliche Massengüter, denn ist ein Flugzeug erst einmal gestartet, haben seine Sitzplätze keinen Wert mehr. Aus diesem Grund wurde bei Fluglinien schon sehr früh nach neuen Distributionsmöglichkeiten in Form von elektronisch...

Algorithmic skeleton has received attention as an efficient method of parallel programming in recent years. Using the method, the programmer can implement parallel programs easily. In this study, a set of efficient algorithmic skeletons is introduced for use in implementing parallel genetic algorithm (PGA).A performance modelis derived for each skeleton that makes the comparison of skeletons po...

If you’re a scifi aficionado, you know that this is how cyborgs get their start. Charles Lieber, a chemist at Harvard University, and his colleagues have injected the brains of the mice with tiny, meshlike electronic ...
