Estimating forage mass of tall fescue pastures and dry matter intake and digestibility of fescue forage by beef steers
… conducted with confined animals to determine the recovery rate of chromic oxide and alkanes from controlled release capsules and to evaluate the accuracy of the concurrent estimations of intake and digestibility. No difference was found in the recovery rate of either alkanes or chromic oxide …

RECYCLING OF PRECIOUS METALS FROM WASTE PRINTED CIRCUIT BOARDS VIA A COMBINATION OF PYRO AND HYDROMETALLURGICAL PROCESSES
… were effectively dissolved via HNO3 with a high recovery rate of 99 wt% to facilitate the extraction of precious metals. Ag and Pt were also successfully dissolved with a recovery rate of >95 wt% in the first stage of leaching. Subsequently, thiourea was applied, and various parameters (including …

An investigation into the effects of preleach time period, nitrogen supplementation and iron concentration on bioleaching performance
… developed into a very important process for the recovery of valuable metals, particularly from low grade copper ores due to the ever increase in demand. A lag phase is present during the start-up phase of heap bioleach operations characterised by a low degree of microbial colonisation, a low …

Contributions to modeling parasite dynamics and dimension reduction
… in Kenya. Understanding the infection and recovery rate from parasitic infections is valuable for public health planning. Two challenges in modeling these rates are (1) infection status is only observed at discrete times even though infection and recovery take place in continuous time and …

Particles and Bubbles Collisions Frequency in Homogeneous Turbulence and Applications to Minerals Flotation Machines
… flotation model for predicting the pulp recovery rate in froth flotation machines. In the direct numerical simulations work, particles and bubbles suspended in homogeneous isotropic turbulence are tracked and their collisions frequency is determined as a function of particle Stokes …

Ability Estimation Under Different Item Parameterization and Scoring Models
… for a given IRT model was assessed by the recovery rate and the root mean square errors. The results indicated that polytomous models produced more accurate ability estimates than the dichotomous models, under all combinations of research conditions, as indicated by higher recovery rates …

Aerogels for energy storage applications: From shape memory materials to thermites and explosives
… external stimulus such as temperature. To incorporate those properties, shape memory polymeric aerogels (SMPA) were synthesized from a rigid isocyanurate containing triisocyanate (N3300 A) and four short oligomeric derivatives of ethylene glycol: H(OCH<sub>2</sub>CH<sub>2</sub>)<sub>n</sub>OH (1 ≤ …
