Comparing Variety Trial and Commercial Data: Trends and Relationships for Practical Use in the South African Sugarcane Industry
The Variety Evaluation Project at SASRI involves conducting variety trials throughout the South African sugar industry. A general trend is that trial yields consistently exaggerate commercial yields obtained by growers under the same conditions. The objective of this study was to use historic variety trial and commercial yield data to evaluate the possibility of using correction factors and plo...
متن کاملThe Impact of Blood Sampling Site on Pain Score in Preterm Infants: A Crossover Randomized Clinical Trial
Background Blood sampling is a usual and painful procedure on preterm infant. Repeating painful procedures may affect the process of normal brain development and Pain management is important for nurses. This study was conducted to evaluate and compare pain score in two sites of blood sampling in preterm infants. Materials and Methods Blood sampling is a usual and painful procedure on preterm in...
متن کاملSampling and Stability
In Numerical Analysis one often has to conclude that an error function is small everywhere if it is small on a large discrete point set and if there is a bound on a derivative. Sampling inequalities put this onto a solid mathematical basis. A stability inequality is similar, but holds only on a finite–dimensional space of trial functions. It allows to bound a trial function by a norm on a suffi...
متن کاملValuing Trial Designs from a Pharmaceutical Perspective Using Value-Based Pricing.
Our aim was to adapt the traditional framework for expected net benefit of sampling (ENBS) to be more compatible with drug development trials from the pharmaceutical perspective. We modify the traditional framework for conducting ENBS and assume that the price of the drug is conditional on the trial outcomes. We use a value-based pricing (VBP) criterion to determine price conditional on trial d...
متن کاملThe Effect of Vanilla Odor on Response to Venipuncture Pain in Preterm Newborns: a Randomized Control Clinical Trial
Background: Studies have shown that use of olfactory stimuli during painful medical procedures reduces infants’ response to pain. Aim: The main purpose of this study was investigating the effect of vanilla on pain response in preterm infants during and after venipuncture. Methods: This study is a randomized clinical trial. Ninety preterm infants, who were randomly selected and divided into two ...
متن کاملEffect of Blood Sampling Site on the Changes in the Physiological Indices of Preterm Infants: A Crossover Clinical Trial
Background: Venipuncture is one of the most painful and common interventions in Neonatal ward. A preterm infant can not cope long-lasting physiologic stresses; therefore, the pain caused by blood sampling may change the infant’s physiologic responses to the stress. This present study aim is to investigated and compare physiologic changes (pulse rate and oxygen saturation) in two sites of blood ...
