Solitons and nonsmooth diffeomorphisms in conformal nets [PDF]

open access: yes, 2018
We show that any solitonic representation of a conformal (diffeomorphism covariant) net on S^1 has positive energy and construct an uncountable family of mutually inequivalent solitonic representations of any conformal net, using nonsmooth ...

Comparison of mathematical and comparative slaughter methodologies for determination of heat production and energy retention in broilers

open access: yesPoultry Science, 2020
Understanding factors affecting ME availability for productive processes is an important step in optimal feed formulation. This study compared a modelling methodology with the comparative slaughter technique (CST) to estimate energy partitioning to heat ...

Net Energy Index: A New Way To Measure Energy Efficient Buildings [PDF]

open access: yes, 2020
Energy efficiency indexes are useful for providing tangible measurements of energy efficiency in buildings. Buildings use approximately 70% of all electricity in the USA.

Metabolizable and net energy values of corn stored for 3 years for laying hens

open access: yesPoultry Science, 2020
The apparent metabolizable energy (AME), AME corrected to zero-nitrogen retention (AMEn), and net energy (NE) values of 2 corn samples both stored for 3 yr were determined in laying hens with reference diet substitution method.

Evaluating and predicting net energy value of wheat and wheat bran for broiler chickens [PDF]

open access: yesAnimal Bioscience, 2022
Objective It is crucial to accurately determine the net energy (NE) values of feed ingredients because the NE system is expected to be applied to the formulation of broilers feed. The NE values of 5 wheat and 5 wheat brans were determined in 12-to 14-day

Charged particle interaction with a chirped electromagnetic pulse [PDF]

open access: yes, 2003
It is found that a charged particle can get a net energy gain from the interaction with an electromagnetic chirped pulse. Theoretically, the energy gain increases with the pulse amplitude and with the relative frequency variation in the ...

Magnetic heating across the cosmological recombination era: Results from 3D MHD simulations [PDF]

open access: yes, 2018
The origin of cosmic magnetic fields is an unsolved problem and magnetogenesis could have occurred in the early Universe. We study the evolution of such primordial magnetic fields across the cosmological recombination epoch via 3D magnetohydrodynamic ...

Evaluation of the Equations to Predict Net Energy Requirement for Lactation in the Cattle Feeding System: Based on the Literature Database

open access: yesAgriculture, 2022
The net energy requirement for lactation (NEL) equals the milk energy, which is the sum of the energy content from the energy-yielding nutrients in milk. The specific nutrients and their calories, however, vary depending on the feeding system.

Design of a 130 MW Axial Turbine Operating with a Supercritical Carbon Dioxide Mixture for the SCARABEUS Project

open access: yesInternational Journal of Turbomachinery, Propulsion and Power
Supercritical carbon dioxide (sCO2) can be mixed with dopants such as titanium tetrachloride (TiCl4), hexafluoro-benzene (C6F6), and sulphur dioxide (SO2) to raise the critical temperature of the working fluid, allowing it to condense at ambient ...

Energy nutritional requirements for females of Nellore, Nellore × Angus and Nellore × Simmental fed on two forage: concentrate ratios

open access: yesRevista Brasileira de Zootecnia, 2012
The objective of this study was to determine the energy nutritional requirements for females of Nellore, Nellore × Angus and Nellore × Simmental fed on two levels of concentrate. Sixty heifers from three genetic groups were used: 20 Nellore, 20 Nellore ×
