Dynamic Vehicle Routing Problem is a more complex version of Vehicle Routing Problem, closer to the present, real-world problems.Heuristic methods are used to solve the problem as currys dyson dc40 Vehicle Routing Problem is NP-hard.Among many different solution methods, the Ant Colony Optimization algorithm is proven to be the efficient solution w
Historical and contemporary DNA indicate fisher decline and isolation occurred prior to the European settlement of California.
Establishing if species contractions were the result of natural phenomena or human induced landscape changes is essential for managing natural populations.Fishers (Martes pennanti) in California occur in two geographically and genetically isolated populations in the northwestern mountains and southern Sierra Nevada.Their isolation is hypothesized t
Goose parvovirus, goose hemorrhagic polyomavirus and goose circovirus infections are prevalent in commercial geese flocks in Poland and contribute to overall health and production outcomes: a two-year observational study
Abstract Background The intensification of poultry production and the constantly growing number of geese flocks in Poland increases the risk of infectious diseases.The study aimed to determine the health status of commercial geese, with particular emphasis on infections with goose parvovirus (GPV), goose circovirus and goose hemorrhagic polyomaviru
