The food manufacturing industry, in general, has always been a highly competitive business but no branch of it is more so than dehydration. Profitability hinges on so many factors, some of which are outside the manufacturer's control. One of the main hazards in this context is that of climate. Total solids in raw materials are the key to a viable operation, and, if these are low, due to wet growing conditions, the plant throughput is going to be seriously reduced

boosted global trade and triggered a surge in commodity prices: The Economist's metals index is at ten-year From budding to blooming high. This has been a fillip to raw-materials producers, GDP growth, annual average such as Brazil, South Africa and Russia. Low global %2001-04 interest rates have also reduced debt-servic costs, and

Handout 8: Lead compensation Eric Feron March 1, 2004 Lead Compensation goals: Raise phase( gain) at high frequen cies while not touching low-frequency system's characteristics: Can extend bandwidth of system. Canonical lead element:

In modern dairy technology, milk is almost always subjected to a heat treatment; typical examples are: Thermization e.g.65°℃×15s Pasteurization LTLT (low temperature, long time) 63C 30 min HTST(high temperature, short time) 15s Forewarming(for sterilization)

Sputter deposition: Read Plummer Chap 9, Sections 9.2.2.2 to 9.3.10. Consider reading Ohring 1. You need to deposit a high quality (low electrical resistivity) Al film at a very high rate(v> I micron/min) and achieve good step coveage using sputter deposition

Acute(急性) and chronic(慢性) toxicity Acute toxicity refers to a rapid and serious response to a high but short-lived dose Acute poisons interfere with essential physiological processes, leading to a variety symptoms of distress, even death Chronic toxicity refers to a time-lagged response to a relatively low but prolonged exposure

Toxic metals Some metals are essential for the normal development and well-being of humans and other creatures They include Na, K, ca, Mg, cu, Cr, and Zn Other metals are toxic even when present in an organism at very low concentrations Examples: Antimony, Arsenic, Barium
