We evaluated and compared various broken-line regression models and SAS (SAS Inst. Inc., Cary, NC) procedures for estimating nutrient requirements from nutrient dose response data. We used the SAS (Version 9) procedures NLIN and NLMixed and the response data of Parr et al. (2003), who evaluated the isoleucine requirement of growing swine. The SAS NLIN was used to fit 2 different broken-line reg...

Cereal grains are considered by consumers due to effect on health because of their antioxidant capacity, phenolic content and other phytochemicals. For this purpose, an experiment was conducted to evaluate of morphological and nutritional traits on 10 rice genotypes. Analysis of variance showed a significant different among the genotypes for all traits. Onda, Gharib, Fajr and L2 genotypes had t...

Low caloric sweeteners have been investigated to substitute sugar as an advantage for both nutritional and medicinal purpose. These sugar substitutes are interesting particularly for concepts marketed under a natural claim. Among these, Stevia rebaudiana is a small shrub; its leaves are used as a sweetener. Serial dilution of the hot water Crude extract of S. rebaudiana leaves and aqueous solut...

The concept of multifractality is currently used to describe self-similar and complex scaling properties observed in numerous biological signals. Fractals are geometric objects or dynamic variations which exhibit some degree of similarity (irregularity) to the original object in a wide range of scales. This approach determines irregularity of biologic signal as an indicator of adaptability, the...

Statistical analysis of data collected in experimental or observational studies is an important part of nutritional research. If it is not done appropriately, there is a risk that information in the data is lost, or that conclusions are misleading. The present article does not attempt a full review of the subject of statistics, but attempts to list aspects where care is needed.
