This paper discusses Virtual Reality as a metaphor for accessing information in structured Web sites. A model for information classification is presented, and an architecture for generating VR interfaces according to a Web site structure is illustrated. Assuming that XML is a viable choice for describing Web documents semantics, some comments stemming from a prototype implementation are discussed.

Foodstuffs analysis is very important due to population growth and increasing consumer demand for safety and nutritional excellence. The Analysis of different compounds in foodstuffs is so difficult without using sample preparation techniques. Traditional techniques require large amounts of toxic organic solvents. As a result, they are not only expensive but also environmentally unfriendly and ...

BACKGROUND Patients with cardiovascular system diseases having their origin in arteriosclerosis require special dietetic treatment. Among many nutritional components, fats in the diet (both their quantity and quality) play a very important role in primary and secondary prevention of these diseases. OBJECTIVES The aim of the study was the estimation of total fats participation (saturated fatty...

Marine mammal foraging behaviour inherently depends on diving ability. Declining populations of Steller sea lions may be facing nutritional stress that could affect their diving ability through changes in body composition or metabolism. Our objective was to determine whether nutritional stress (restricted food intake resulting in a 10% decrease in body mass) altered the calculated aerobic dive ...

Currently parenteral nutrition is a recognized supplement of surgical treatment. Often this therapy enables a surgical procedure to be conducted without putting the patient at risk of unnecessary complications related to malnutrition (1). Administration of proper nutritive facilitates quicker recovery in the postoperative period and in cases of radical intestinal resection, nutritional treatmen...

There has been an increase in Australia's intake of refugees and migrants from sub-Saharan Africa over the last two decades. These refugees have been exposed to nutritional risks prior to migration, which, together with changes associated with acculturation, impact on their health and nutritional status post-migration. However, there is a paucity of data in Australia that has examined the healt...

It is the position of the Academy of Nutrition and Dietetics that nutritional genomics provides insight into how diet and genotype interactions affect phenotype. The practical application of nutritional genomics for complex chronic disease is an emerging science and the use of nutrigenetic testing to provide dietary advice is not ready for routine dietetics practice. Registered dietitian nutrit...

background and objective: malnutrition is a very common clinical disorder risk factor in elderly people, which is not diagnosed in most cases and, therefore, remains untreated. the objective of this study was to determine the prevalence of malnutrition in free-living elderly people and its relationship with socioeconomic factors (sef) in the elderly subjects in khorasan razavi province, iran. m...

Many individuals with short bowel syndrome (SBS) require long-term parenteral nutrition (PN) to maintain adequate nutritional status. Herein, we report a successful intestinal adaptation of a patient with SBS through 13 times intensive nutritional support team (NST) managements. A thirty-five-year-old woman who could not eat due to intestinal discontinuity visited Seoul National University Hosp...
