Large electrocaloric effects in single-crystal ammonium sulfate

Ammonium Chloride and Ammonium Sulfate in Cattle Feedlot Finishing Rations

T WO levels of ammonium chloride or of ammonium sulfate were added to the rations of commercial feeder cattle. The rations were made isonitrogenous, essentially isocaloric and to contain the same level of calcium, phosphorus and salt. Total gains were essentially the same for all lots, varying only 15.6 lb (7.1 kg) over a 112 day feeding period. Feed conversion was increased only on the ration ...

Double hysteresis loops and large negative and positive electrocaloric effects in tetragonal ferroelectrics.

Phase field modelling and thermodynamic analysis are employed to investigate depolarization and compression induced large negative and positive electrocaloric effects (ECEs) in ferroelectric tetragonal crystalline nanoparticles. The results show that double-hysteresis loops of polarization versus electric field dominate at temperatures below the Curie temperature of the ferroelectric material, ...

Effects of nitroxin and ammonium sulfate on some of the traits of Marrubium vulgare L.

In order to study the effect of nitroxin bio-fertilizers (0, 3 and 6 liters per hectare) and ammonium sulfate fertilizer (0, 75 and 150 kg.ha-1) on yield, phytochemical, phenotypic and trace elements of Marrubium vulgare L., a factorial experiment based on completely randomized block design with three replications was conducted at Zanjan University in 2017. Nitroxin bio-fertilizer and ammonium ...
