Heat production model by a heat pump

open access: yesIOP Conference Series: Earth and Environmental Science, 2022
Abstract The article deals with the possibility of determining the consumption of electrical energy by heat pumps. In the course of research experimental measurements have been made and energy characteristics of heat pump have been determined. The parameters of the heat pump, which essentially influence the degree of heat production, are

Effect of high dietary fat content on heat production and lipid and protein deposition in growing immunocastrated male pigs1

open access: yesAnimal, 2016
In immunocastrated (IC) pigs, revaccination (V2) increases lipid deposition (LD) because of increased voluntary feed intake; but little is known on associated effect of diet composition on partitioning of nutrients in IC pigs. Digestibility measurements,

Contribution of the 2010 Maule Megathrust Earthquake to the Heat Flow at the Peru-Chile Trench

open access: yesEnergies, 2022
The 2010 Maule earthquake was a megathrust event that occurred along the Peru–Chile Trench. The earthquake source can be modelled as a fault with two asperities with different areas and strengths. By employing a discrete fault model, where asperities are
