Nutrient density, the vitamin or mineral content of a food or diet per unit energy, has long been a useful concept in the nutritional sciences. However, few nutritionists have applied the idea in quantitative, population-based nutrition planning and assessment. This paper discusses the conceptual issues related to the calculation of a nutrient density value that, if consumed, should meet the nu...

The 80% of bone mineralisation occurs in the third trimester of pregnancy. The daily fetal requirement is 310 mg of calcium and 170 mg of phosphorus [1]. The bone mineral density (BMD) correlates positively with gestational age, weight and length [2]. At birth, extremely premature infants (ELBWI)canpresent hypocalcaemia because of interruption of the maternal calcium supply, high level of calci...

Abstract. The information given here is provided by the IMA Commission on New Minerals, Nomenclature and Classification for comparative purposes as a service to mineralogists working new species. Each mineral described in following format: name, if authors agree its release prior full description appearing press; chemical formula; type locality; authorship of proposal; e-mail address correspond...

Twenty-six crossbreed (Yorkshire x Landrace) sows bred to Duroc boars were used to determine fetal measurements and mineral compositions at various stages of gestation. Sows were fed a vitamin and mineral fortified 15% CP corn soybean meal gestation diet fed at 2.1 kg daily with dietary minerals meeting or in excess of NRC requirements. Sow and litter measurements were evaluated at 5 periods po...

Salvadora persica is a medicinally important plant mainly used in oral hygiene. However, little attention has been given towards the nutritional prominence of this plant. This study encloses the proximate and mineral nutrient contents, amino acid composition, metabolite profiling and antioxidant potential of S. persica fruit. The ripen fruit contained substantial amount of sugars, mineral nutri...

the present research was conducted to estimate the dietary lysine (lys) requirement of growing female quail base on performance and carcass constitutes at 24 to 42 d of age. a dose-response diet mainly based on corn, corn gluten and soybean meal was used. lys content was minimized in dose-response diet (10 g/kg) while assuring the minimum levels of all other essential amino acids in a manner th...

The influence of calcium to phosphate (Ca/P) molar ratio on the extent of mineralization in a model (poly)acrylamide gel was investigated under simulated physiological conditions. We hypothesized that the optimal growth of hydroxyapatite crystals will take place at the stoichiometric Ca/P molar ratio of 1.67. Phosphate ions were incorporated during the polymerization of the gel and mineralizati...

Two experiments are described in which changes in both nitrogen and mineral balance were monitored in ewes during lactation. In Expt 1, two groups (n 6) of ewes were fed on diets that were either high (15 g crude protein (N X 6.25; CP)/MJ metabolizable energy (ME)) or low (10 g CP/MJ ME) in protein content, and concurrent N and mineral balance studies were made at intervals during lactation wit...

Leaf kale is a crop that widely consumed today due to the new ways of using it in cooking and its nutritional properties. However, has high requirement for nitrogen fertilization, so excessive application mineral fertilizers causes environmental impacts. Considering importance requirement, objective this work was evaluate effect organomineral fertilization on development cv. Butter. The treatme...

Abstract The use of rubber in asphalt mixtures is a new thing nowadays, but practice its has not been fully implemented throughout Indonesia. approach using local materials made many researchers perform various combinations, this study one the combinations used material testing characteristics on AC-WC ( Asphalt Concrete Wearing Course ) layer. purpose was to determine from variation mixing wit...
