Quality and Safety Aspects of Infant Nutrition

Quality and safety aspects of infant nutrition are of key importance for child health, but oftentimes they do not get much attention by health care professionals whose interest tends to focus on functional benefits of early nutrition. Unbalanced diets and harmful food components induce particularly high risks for untoward effects in infants because of their rapid growth, high nutrient needs, and their typical dependence on only one or few foods during the first months of life. The concepts, standards and practices that relate to infant food quality and safety were discussed at a scientific workshop organized by the Child Health Foundation and the Early Nutrition Academy jointly with the European Society for Paediatric Gastroenterology, Hepatology and Nutrition, and a summary is provided here. The participants reviewed past and current issues on quality and safety, the role of different stakeholders, and recommendations to avert future issues. It was concluded that a high level of quality and safety is currently achieved, but this is no reason for complacency. The food industry carries the primary responsibility for the safety and suitability of their products, including the quality of composition, raw materials and production processes. Introduction of new or modified products should be preceded by a thorough science based review of suitability and safety by an independent authority. Food safety events should be managed on an international basis. Global collaboration of food producers, food-safety authorities, paediatricians and scientists is needed to efficiently exchange information and to best protect public health. Copyright (C) 2012 S.

The effect of heating rate on the recrystallization behavior of high gamma\u27, ods superalloys

Directional recrystallization is an essentail step in the production of ODS nickel-based alloys with high gamma\u27-content, such as MA 6000 and MA 760. The rate of heating to the recrystallizationtemperature plays an important role for the final grain structure. This can be explained by the development of a certain "primary" grain size during the heating period.An additional aspect is the existence of heating rate limits, which determine the success of the recystallization. The existence of a critical minium heating rate (T min) is related to normal grain growth, which reduces the driving force for subsequent abnormal grain growth. Surprisingly, recent investigations have also revealed in some cases the occurrence of a ritical maximum heating rate (T max). In this paper an attempt is made to explain this new phenomenon, which may have important practical implications, through the formation of different carbide phases

Technische Hogeschool Delft - Laboratorium voor Metaalkunde

Beschrijving van het in 1961 gereed gekomen nieuwe gebouw voor Metaalkunde van de Technische Hogeschool Delft, op de hoek Jaffalaan / Rotterdamseweg te Delft. Het werd geopend op 4 oktober 1961. Het ontwerp is van het architectenbureau Van den Broek en Bakema. In het begin van de jaren 2000 werd het gesloopt. In het boekje ontbreekt helaas een afbeelding van het zeer kleurrijke wandmozaiek dat zich in de aankomsthal bevond.Technische Materiaalwetenschappen (MSE)Mechanical, Maritime and Materials Engineerin
