Antibiotic Resistence of enterococci

This study was conducted to evaluate the antibiotic resistance of enterococci isolated from poultry in the wilaya of Tizi Ouzou. A total of 137 enterococci isolates from poultry were tested for antibiotic susceptibility by the diffusion method. Ten antibiotics from different families were tested. High percentages of resistance to Tetracycline and Erythromycin were

Recent emergence of CAT5 tropical cyclones

The IBTrACS global best track data set endorsed by the World Meteorological Organization provides a valuable global record of tropical cyclone genesis, track and intensity, and spans 1842 to the present. The record is significantly more robust from the late 1970s onwards, as it is supported by satellite imagery. These records indicate that

Insights on Forest Structure and Composition

The science of ecology fundamentally aims to understand species and their relation to the environment. At sites where hurricane disturbance is part of the environmental context, permanent forest plots are critical to understand ecological vegetation dynamics through time. An overview of forest structure and species composition from two of the longest continuously measured

Antioxidant potential of selected underutilized fruit crop species grown in Sri Lanka

Lyophilized aqueous extracts of four underutilized fruit species namelyDiospyros discolor (Velvet apple), Pouteria campechiana (Lavulu/Canistel), Phylanthusacidus (Mal-Nelli/Star gooseberry) and Phyllanthus emblica (Nelli/Indian gooseberry) were investigated for the antioxidant potential (AP) by 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, 2,2-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) assay and ferrousreducing antioxidant power (FRAP) assay. Total phenolic content (TPC) and total monomeric anthocyanin content

Radiation-Driven Stellar Eruptions

Very massive stars occasionally expel material in colossal eruptions, driven by continuum radiation pressure rather than blast waves. Some of them rival supernovae in total radiative output, and the mass loss is crucial for subsequent evolution. Some are supernova impostors, including SN precursor outbursts, while others are true SN events shrouded by material
