The intensive harvesting of hosts is often the only practicable strategy for controlling emerging wildlife diseases.Several harvesting approaches have been explored theoretically with the objective of lowering transmission rates, decreasing the transmission period or specifically targeting spatial disease clusters or high-risk demographic groups.He
Papilloma viruses (PVs) are non-enveloped, small, double stranded DNA viruses with circular genomes that replicate intranuclearly in infected Purse cells.Papilloma viruses have high affinity for stratified squamous epithelia of warm blooded animals including cattle and occurs in all animal species throughout the world, and are highly species-specif
The dengue virus (DENV), transmitted by Aedes spp.mosquitoes, is one of the most important arboviral infections in the world.Dengue begins as a febrile Hunting Jackets condition, and in certain patients, it can evolve severe clinical outcomes, such as dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS).The reasons why certain patients de
Increase of axle load and wagon numbers of heavy haul train would generate larger longitudinal train impulse in the condition of shunting impact, and it would result in some dangerous problems.On the basis of draft gear dynamic modification model, the vehicle impact equation and vehicle-coupler-vehicle series model, the effect of different braking
