Nutritional assessment by diet analysis is a two-stepped process consisting of evaluation of food consumption, and conversion of food into nutrient intake by using a food composition database, which lists the mean nutritional values for a given food portion. Most reports in the literature focus on minimizing errors in estimation of food consumption but the selection of a specific food compositi...

Controlled release fertilizers (CRF) are produced with different rates and durations of nutrient release to cater to different crops with wide ranges of nutrient requirements. A rapid technique is needed to verify the label specifications of nutrient release rate and duration. Polymer-coated urea (PCU) (43% nitrogen [N]) and polymer-coated N, phosphorus (P), potassium (K) (PC_NPK; 14-14-14) fer...

Edge effects represent an inevitable and important consequence of habitat loss and fragmentation. These effects include changes in microclimate, solar radiation, or temperature. Such abiotic effects can, in turn, impact biotic factors. They can have a substantial impact on species, communities, and ecosystems. Here we examine clinal variations in stable carbon and nitrogen isotope values for tr...

Studies have indicated that consistent or well-constrained (relatively low variability) carbon:nitrogen:phosphorus (C:N:P) ratios exist in large-scale ecosystems, including both marine and terrestrial ecosystems. Little is known about the C, N and P stoichiometric ratios that exist in the soils and plants of Chenier Island in the Yellow River Delta (YRD). We examined the distribution patterns a...

Valerian (Valeriana dioscoridis Sm.) is a perennial herb of the Caprifoliaceae family. The aim this study was to determine variation V. plants grown in different regions respect quality criteria traits such as nutrient values, extract contents and vitro antioxidant antimicrobial activity values. In study, roots rhizomes Sm. were collected from eight locations Antalya province. obtained material...

UNLABELLED OBJECTIVE, METHODS AND RESULTS: Nutri-Educ is a nutrition software application developed in cooperation with the Diabetology Department of Toulouse's Rangueil University Hospital. It aims at helping any person to balance their meals. More specifically, its main goal is to enable a user to describe a meal and assess its content, and in most cases to find a small set of acceptable acti...

This survey provides baseline information on sediment characteristics, porewater, adsorbed and plant tissue nutrients from intertidal coastal seagrass meadows in the central region of the Great Barrier Reef World Heritage Area. Data collected from 11 locations, representative of intertidal coastal seagrass beds across the region, indicated that the chemical environment was typical of other trop...

OBJECTIVE In 1998, the Canadian government mandated folic acid fortification of white flour and enriched grain products to lower the prevalence of neural tube defects. There is now growing concern over the potential harmful effects of too much folic acid on some segments of the population. Given that the actual amount of folate in Canadian foods is unknown, the objective of this study was to me...

There are few studies in children, particularly in the UK, aimed at examining relationships between the intake of specific micronutrients and currently accepted biochemical/functional indices of status. Consequently, the normal range of values for biochemical indices of status in this age-group, and the functional significance of low biochemical status, is unknown. Hence, dietary requirements h...

Key features of USDA’s Nutrient Databank System (NDBS) allow processing of food composition data from diverse sources, including USDA’s National Food and Nutrient Analysis Program, the food industry, scientific literature, and food labels. The Nutrient Data Laboratory (NDL) designed the NDBS as a threetiered (‘‘Initial’’, ‘‘Aggregation’’, and ‘‘Compiled’’) data management system to facilitate h...
