Many engineering design optimization problems can be represented as mixed-variable optimization problems.This study presents a heuristic approach for solving mixed-variable optimization using rotation and contraction of vectors.The current optimization algorithm, known as rotate-vector, has shown promising results in solving optimization problems w
Current methods of euthanizing piglets are raising animal welfare concerns.Our experiment used a novel two-step euthanasia method, using nitrous oxide (N2O) for six minutes and then carbon dioxide (CO2) Natural Gas Conversion Kit on compromised 0- to 7-day-old piglets.A commercial euthanasia chamber was modified to deliver two euthanasia treatments

Cyanobacterial harmful algal bloom (CyanoHAB) proliferation is a global problem impacting ecosystem and human health.Western Lake Erie (WLE) typically endures two highly toxic CyanoHABs during summer: a Microcystis spp.bloom in Maumee Bay that extends throughout the western basin, and a Planktothrix spp.bloom in Sandusky Bay.Recently, the USA and C
The rio LANTERN Ivaí flows through the left margin of the upper rio Paraná basin with 798 km of extension, being one of its largest tributaries.In this study, we analyzed 586 specimens of Hypostomus Lacépède, 1803 from the rio Ivaí basin deposited in the Coleção de Peixes
