Incorporating Environmentally Compliant Manure Nutrient Disposal Costs into Least-Cost Livestock Ration Formulation [PDF]

Livestock rations are formulated to minimize feed cost subject to nutritional requirements for a target performance level, which ignores the potentially substantial cost of disposing of nutrients fed in excess of nutritional requirements.

Hydrodynamic interactions in polar liquid crystals on evolving surfaces

, 2019
We consider the derivation and numerical solution of the flow of passive and active polar liquid crystals, whose molecular orientation is subjected to a tangential anchoring on an evolving curved surface.

Effect of maturity at harvest of small-grain grasses on the nutritional composition of forage and ration formulation

Journal of Dairy Science
: We hypothesized that, relative to harvesting small-grain grasses at the soft dough stage (SFT) of maturity, harvesting small-grain grasses at the boot stage (BT) of maturity would result in less expensive dairy rations when commodity prices are high ...

The effect of addition of calcium mineral in feed containing fishery wastes on egg production and hatching performance of Mojosari ducks [PDF]

Brazilian Journal of Biology
Calcium (Ca) is an essential mineral for eggshell formation and muscle contraction, and a lack of it can result in poor egg quality and decreased egg output in laying ducks.

Recent Advances on Self‐Powered Metal Halide Perovskite Photodetectors

EcoEnergy, EarlyView.
This review outlines that metal halide perovskites, with high absorption coefficient and carrier mobility, enable self‐powered photodetectors. These devices operate without external power, with improvements via structural optimization, film engineering, and defect passivation, showing promise in smart sensors and Internet of Things applications ...

Formulating and Estimating Continuous Time Rational Expectations Models [PDF]

, 1981
This paper proposes a method for estimating the parameters of continuous time, stochastic rational expectations models from discrete time observations. The method is important since various heuristic procedures for deducing the implications for discrete time data of continuous time models, such as replacing derivatives with first differences, can ...
