Twenty-four new species of the caddisfly genus Polycentropus (Insecta: Trichoptera: Polycentropodidae) occurring in Brazil are diagnosed, described, and the male genitalia of each are illustrated. Eighteen of the new species are placed in the Polycentropus jorgenseni species complex of the Polycentropus gertschi group of New World Polycentropussensu lato. Furthermore, 6 new species within the P...

Two strong earthquakes with the magnitude of 6.4 and 6.3 at a depth of 9.9 km that rattled Iran’s northwest region within 60 km of Tabriz, the capital city of East Azerbaijan province on August 11, 2012 caused extensive damage in about 1000 villages, killed at least 258 and injured 1380 people. The quakes most severely affected villages close to three impacted towns in the disaster area; Varzeg...

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...

This work presents a new approach to ensure compliance to legal regulation in Cloud Computing, especially in Software-as-a-Service. Since high demanding business sectors, such as the health care sector, require high legal certainty, when contracting services offered by external providers. We provide a lightweight ontological representation of the German Federal Data Protection Act (BDSG) and a ...

TEI-1194, sodium 6-[D-(-)-alpha-(coumarin-3-carboxamide)-phenylacetamide] penicillanate and TEI-2012, sodium 6[D-(-)alpha-(8-hydroxy-coumarin-3-carboxamide)-phenylacetamide] penicillanate are new semisynthetic penicillin derivatives both possessing a broad spectrum of in vitro antibacterial activities. Minimal inhibitory concentrations of both agents were compared with carbenicillin. TEI-1194 a...

BACKGROUND Reported age standardized incidence rates for esophageal cancer in Iran are 0.88 and 6.15 for females and males, at fifth and the eighth ranks, respectively, of cancers overall. The present study aimed to map relative risk using more realistic and less problematic methods than common estimators. MATERIALS AND METHODS In this ecological investigation, the studied population consiste...
