This research focusses on the biostratigraphy and paleoecological implications of the carbonatesof the Asmari Formation. The Asmari Formation is located in the Siah Kuhanticline of Izeh, Zagros Basin, SW Iran. It is of Late Oligocene (Chattian) - Early Miocene (Burdigalian) age. In this stratigraphic section, the Asmari Formation overlies the Pabdeh Formation and underlies the Gachsaran Formati...

Nothronychus was the first definitive therizinosaurian discovered in North America and currently represents the most specialized North American therizinosaurian genus. It is known from two species, No. mckinleyi from the Moreno Hill Formation (middle Turonian) in west-central New Mexico, and No. graffami from the Tropic Shale (early Turonian) in south-central Utah. Both species are represented ...

KD har i en nylig proposisjon foreslått endringer av klagesensurordningen, hvor det legges opp til at en modell med blind omsensur, som allerede har vært brukt ved en del læresteder, nå skal gjøres obligatorisk for alle læresteder. I denne artikkelen sammenlignes gammel og ny klagesensurordning med ordningene i en del andre land. Vi diskuterer ulike typer sensurfeil (med eksempel fra programmer...

1. It has been shown that factor V accelerates the rate of conversion of prothrombin into thrombin by activated factor X, and that this activity does not depend on the presence of phospholipid. 2. Although the mechanism by which factor V increases the rate of reaction is not clear, it seems unlikely that it is converted into an enzyme. 3. The rate of conversion of prothrombin by purified activa...

The relation between the cover (Tukey type) uniformities and the entourage (Weil type) ones, in the point-free context, is studied and a transparent translation is presented. In particular the natural uniformities on localic groups are discussed, and the uniformity of localic group homomorphisms is proved.

A general ized model of rough sets called variable precision model (VP-model), a imed at modell ing classification problems involving uncertain or imprecise information, is presented. The general ized model inherits all basic mathematical propert ies of the original model introduced by Pawlak. The main concepts are introduced formally and illustrated with simple examples. The application of the...
