If that is not the case, then it is straightforward to make axiom use frequencies nutrient dependent.
We evaluated the effects of harvest frequency and nutrient sources on yield and quality of switchgrass for biofuel feedstock.
Media for the batch and fed stages were based on the cell specific amino acid requirements, which allowed a more accurate determination of the initiation of the fed stage and the frequency of nutrient addition from then on.
Moreover, the system, which can be deployed in any aquatic habitat, can be manipulated like 'standard' settlement plates and will thus facilitate complex field experiments that combine multiple stressors (i.e. temperature with disturbance frequency or nutrient enrichment) and examine species interactions (i.e. competition vs. facilitation) within functional communities.
Low meal frequency, low nutrient content, small portion size and limited variety reduced the contribution of meals to daily nutritional needs.
No independent reference method used in the comparisons of FETA and CAFÉ (Compositional Analyses from Frequency Estimates) nutrient intake data although the CAFÉ system has been previously validated.
Models contained row- and column effects (fitted as factors, column was nested within block), sward composition (factor with three levels), cutting frequency and nutrient input (two levels each) with up to two-way-interactions.
Based on our findings and those of others, we recommend that clinical intervention trials be initiated amongst older populations, both in and out of the hospital setting, to determine the usefulness of this strategy in combating the high frequency of nutrient deficiencies in this population.
By combining information obtained from the food frequency questionnaire with nutrient values provided in this food-nutrient database accounting for raw and cooked foods, we were able to compute the mean daily intakes of nutrients for each subject (11).
We did not elucidate upon how vitamin D is acquired from diet for the following reasons: 1) only a limited amount of information regarding vitamin D content in Thai foods is available [ 26]; and, 2) a validated food frequency questionnaire and nutrient calculation program for vitamin D in Thai foods are also not currently available.
