It has been suggested that a few methanogens are capable of extracellular electron transfers.For instance, Methanosarcina barkeri can directly capture electrons from the coexisting microbial cells of other species.Methanothrix harundinacea and Methanosarcina horonobensis retrieve electrons from Geobacter metallireducens via direct interspecies elec
High Explosive Anti-Tank (HEAT) warheads and ammunitions are frequently produced by explosive casting inside an axis-symmetric mold with an inverted conical geometry in the basis.In order to prevent manufacturing defects, the solidification process must be controlled.In this study, a dimensionless solidification model has been proposed to investiga
Abstract Flash droughts and their physical processes have received increasing attention in recent years due to concerns about the potential of flash droughts to affect water resources and ecosystems.Yet to date, the response of ecosystems during flash drought events, particularly on a large scale, and the determinants of the ecosystem responses to
Coconut shells are produced in a vast amount around tropical countries that needs to be utilized properly.Thermochemical methods are the main route for converting biomass to charcoal.Percentage of some relative factors in the biomass such as low-density, low caloric value, high ash, SOX, NOX, moisture content, microstructure, and complex elements a
