Predatory and scavenging birds may be exposed to high levels of lead when they ingest shot or bullet fragments embedded in the tissues of animals injured or killed with lead ammunition.Lead poisoning was a contributing factor in the decline of the endangered California condor population in the 1980s, and remains one of the primary factors Ledinestr

Coral communities are increasingly found to populate non-reef habitats prone to high environmental variability.Such sites include seagrass Charm meadows, which are generally not considered optimal habitats for corals as a result of limited suitable substrate for settlement and substantial diel and seasonal fluctuations in physicochemical conditions

Pears of different varieties were compressed between two flat rigid plates in loading/unloading tests.The bruise spots appearing after room temperature incubation were analysed manually, and bruise spot volumes were determined.The main parts of the paper discuss mathematical approximation of total bruise volume versus two deformation parameters def

Extracting the precise parameters of photovoltaic (PV) cells has become very important for simulation, evaluation, control, and optimization of PV systems.However, it is still a challenging task to accurately and reliably extract the parameters of PV cells.To solve this difficult problem, in this paper, a new meta-heuristic algorithm called Gaussia

BACKGROUND: Ectopic pregnancy is the implantation of an embryo at sites outside the uterine cavity.With advances in medicine, non-surgical (medical) therapeutic approaches had been introduced in the management of ectopic pregnancy, and they are gaining wide clinical application.Of such medical therapeutic approaches is the use of methotrexate.The u
