Elm trees and elm leaf beetles: patterns of herbivory

The Diatom EST Database

The Diatom EST database provides integrated access to expressed sequence tag (EST) data from two eukaryotic microalgae of the class Bacillariophyceae, Phaeodactylum tricornutum and Thalassiosira pseudonana. The database currently contains sequences of close to 30,000 ESTs organized into PtDB, the P.tricornutum EST database, and TpDB, the T.pseudonana EST database. The EST sequences were cluster...

digestive amylase and glucosidases in the larval stage of elm leaf beetle, xanthogaleruca luteola (col.: chrysomelidae)

elm leaf beetle, xanthogaleruca luteola, is a serious pest (particularly at its larval stage) of elm trees in many areas. the existence of three important enzyms namely: ?-amylase, ?- glucosidase and ?-glucosidase in the midgut of the insect at its larval stage was investigated. optimum activity for ?-, ?-glucosidase and ?-amylase was recorded at phs 5.0, 6.0 and 6.0 against p-nitrophenyl-?-d-g...

An Authorization Framework for Database Systems

Today, data plays an essential role in all levels of human life, from personal cell phones to medical, educational, military and government agencies. In such circumstances, the rate of cyber-attacks is also increasing. According to official reports, data breaches exposed 4.1 billion records in the first half of 2019. An information system consists of several components, which one of the most im...
