Reduction of predictive uncertainty in estimating irrigation water requirement through multi-model ensembles and ensemble averaging [PDF]
Geoscientific Model Development, 2014 Abstract. Irrigation agriculture plays an increasingly important role in food supply. Many evapotranspiration models are used today to estimate the water demand for irrigation. They consider different stages of crop growth by empirical crop coefficients to adapt evapotranspiration throughout the vegetation period.

BMC Pediatrics, 2022 Background According to the Feeding Infants and Toddlers Study (FITS), the percentage of older infants consuming infant cereal has declined from 72% of 6–11.9 month old infants in 2002 to 52% in 2016. This is especially concerning for breastfed and mixed

Sampling effort required to obtain repeatable average size estimates of juvenile fish [PDF]
Aquatic Biology, 2011 Larval and juvenile fish cohorts often have skewed size distributions due to inter-individual variation in growth rates. A resampling analysis was used to investigate how much sampling effort is required to achieve repeatable average size estimates in populations of juvenile yellowtail kingfish Seriola lalandi Valenciennes.

Dietary Recommendations for Vitamin D: a Critical Need for Functional End Points to Establish an Estimated Average Requirement [PDF]
The Journal of Nutrition, 2005 From its inaugural value in 1941, the Recommended Dietary Allowance (RDA) for adults for vitamin D has remained close to 400 IU (10 microg) level. This original recommended intake was based on the observation that the amount of vitamin D activity in a teaspoon of cod liver oil was sufficient to prevent rickets in infants.

Calculating Estimated Average Requirements (EARs) for zinc (Zn) According to Dietary Phytate
The FASEB Journal, 2008 Background: Estimation of the DRIs (dietary reference intakes) for Zn by the Institute of Medicine (IOM, 2001) specifically included calculations only for phytate‐free diets. The objective of this investigation was to apply a mathematical model (J Nutr, 2007) of daily total absorption of Zn (TAZ) as a function of daily total dietary ...
