Issue: Understanding the chemical composition of container glass is critical to recycling for a number of reasons. First, the chemistry has significant implications for managing the behavior of molten glass in any remelt application, from large-scale container manufacturing down to cottage-industry pressed glass. Second, the composition has important implications for evaluating health concerns ...

as an essential, an exact knowledge of the chemical composition of food. The Medical Research Council in England has for many years past been collecting data of the analytical work of food chemistry done in that country to provide a standard work on the subject. With this object in view an intensive work on the analysis of foodstuff was started by McCance and others at the King's College Hospit...

This chapter includes overall chemical composition of wood, methods of analysis, structure of hemicellulose components and degree of polymerization of carbohydrates. Tables of data are compiled for woods of several countries. Components include: cellulose (Cross and Bevan, holo-, and alpha-), lignin, pentosans, and ash. Solubilities in 1% sodium hydroxide, hot water, ethanol/ benzene, and ether...

this paper presents results of hydro-chemical processes controlling groundwater chemical composition, using an integrated application of hierarchical cluster analysis and factor analysis of a major ion data set of groundwater from mighan playa aquifer. cluster analysis classified samples into four clusters(a, b, c and d) according to their dominant chemical composition: cluster a (dominant comp...

alstroemeria flower is one of the most important cut flowers in the world. some materials can increase longevity of cut flowers. the aim of this research was evaluating the effect of some chemical solutions on postharvest alstroemeria (cv. stratus) cut flowers. this experiment was conducted with two factors of sucrose at four concentrations, 0, 5, 10 and 15 g/l and salicylic acid (sa) at four c...

The performances of outdoor polymeric insulators are influenced by environmental conditions. The use of polymeric materials in a particular composition can be produced insulators that are resistant to environmental influences. This paper presents the effect of artificial tropical climate on the hydrophobicity, equivalent salt deposit density (ESDD), surface leakage current, flashover voltage, a...
