In order to solve the problem of serious damage to coalbed methane reservoir caused by a large amount of residue after gel breaking of conventional guar gum fracturing fluid, a new type of multi-component modified guar gum DX-HPG was developed by alkalization and etherification of conventional guar gum, and a set of CHLORELLA ultra-low concentratio
Study on slurry pump performance has attracted much interest in many engineering fields.When pumps are required to handle slurries.The pump head and efficiency are mainly affected by Hair Styling the solid size, solid concentration and solid density.Centrifugal slurry pumps are benign used extensively for pipeline transportation systems and phospha
Mine tailings are produced by mining activities and contain diverse heavy metal ions, which cause environmental problems and have negative impacts on ecosystems.Different microorganisms, including yeasts, play important roles in the absorption and/or adsorption of these heavy metal ions.This work aimed to analyze proteins synthesized by the yeast Y
High hydrostatic pressure (HHP) causes depolymerization of the spindle microtubules.HHP applied to fish eggs prevents extrusion of the second polar body and inhibits the first cell cleavage, and it is used to produce triploids and diploid gynogenetic and androgenetic individuals.HHP has been also found to affect biomolecules including nucleic acids
Commercial operations of uncrewed aerial vehicles (UAVs or drones) are expanding, with medical logistics using UAVs as part Fasteners of health service supply chains being targeted.The ability to transport cargos that include items classified as Dangerous Goods (DG) is a significant factor in enabling UAV logistics to assist medical supply chains,
