OBJECTIVE To evaluate the relative abrasivity of different toothpastes and polishing pastes both qualitatively and quantitatively. MATERIALS AND METHODS Acrylic plates were exposed to brushing in a brushing machine with a toothpaste/water slurry for 1 and 6 h. Twelve different toothpastes were used and also four different polishing pastes. The results were evaluated using a profilometer after...

Label distribution covers a certain number of labels, representing the degree to which each label describes an instance. The learning process on instances labeled by distributions is called Distribution Learning (LDL). Although LDL has been applied successfully many practical applications, one problem with existing methods that they are limited data balanced information. However, annotation inf...

Vitamin K is required for the carboxylation of Gla-proteins in the liver (coagulation factors) and extra-hepatic tissues, such as bone (osteocalcin, OC), and arterial wall (matrix Gla-protein, MGP). Although the coagulation factors are essentially fully carboxylated under normal conditions, 10-40 % of OC and MGP remains undercarboxylated. We were therefore interested to study the dose-response ...

INTRODUCTION The specific carbohydrate diet (SCD) is an exclusion diet used as a therapy in inflammatory bowel disease. The aim of this study was to evaluate the nutritional adequacy of the SCD. METHODS Prospective dietary data for 12 weeks were analyzed for pediatric patients on the SCD. Intake of 20 key nutrients was compared to dietary recommended intake levels and nutrient intake data fro...

INTRODUCTION While enteral diets for hospitalized patients normally follow nutrient composition guidelines, more than 90% of hospitalized patients receive oral diets with unknown mineral composition. OBJECTIVE To evaluate the mineral contents and adequacy of three types of oral diets (regular, blend and soft) and complementary snacks offered to patients of a Brazilian hospital. METHODS The ...

Food shortage in Sub-Saharan Africa is predominantly taken as a function of limited access to food, with out considering nutritional quality. Analyzing households’ production of nutrients on farm across farming systems could be valuable in guiding intensification of those systems. An optimization model was employed to analyze the scenario of human nutrition and cropland allocation in Enset (Ens...

Food shortage in sub-Saharan Africa is generally considered a function of limited access to food, with little thought to nutritional quality. Analyzing household production of nutrients across farming systems could be valuable in guiding the improvement of those systems. An optimization model was employed to analyze the scenario of human nutrition and cropland allocation in enset (Enset ventric...

The Security functionality provided by the protocols is almost equivalent. While the FTAM and RDA authentication and authorisation mechanisms are a mere mapping to those of the accessed file system or database, DFR defines own mechanisms. No sound statements on efficiency and reliability issues of the protocols can be made right now. These have to be derived from experiences with trial implemen...

Summary Reaction kinetics between calcite and acid systems have been studied using the rotating disk apparatus (RDA). However, simplifying assumptions made to develop current equations used interpret RDA experiments enable solving them analytically in contrast numerical methods. Previous work has revealed inadequacies of some these assumptions, which necessitates use a computational fluid dynam...
