    Summary: Stream Ecology: Structure and Function of Running Waters is designed to serve as a textbook for advanced undergraduate and graduate students, and as a reference source for specialists in stream ecology and related fields. This Third Edition is thoroughly updated and expanded to incorporate significant advances in our understanding of environmental factors, biological interactions, and ecosystem processes, and how these vary with hydrological, geomorphological, and landscape setting. The broad diversity of running waters from torrential mountain brooks, to large, lowland rivers, to great river systems whose basins occupy sub-continents makes river ecosystems appear overwhelming complex. A central theme of this book is that although the settings are often unique, the processes at work in running waters are general and increasingly well understood. Even as our scientific understanding of stream ecosystems rapidly advances, the pressures arising from diverse human activities continue to threaten the health of rivers worldwide. This book presents vital new findings concerning human impacts, and the advances in pollution control, flow management, restoration, and conservation planning that point to practical solutions. Reviews of the first edition: ".. an unusually lucid and judicious reassessment of the state of stream ecology" Science Magazine "..provides an excellent introduction to the area for advanced undergraduates and graduate students" Limnology & Oceanography " a valuable reference for all those interested in the ecology of running waters." .

    A comparision of a high dose of pentazocine (0.9 mg/kg), and moderate doses of pethidine (1 mg/kg) and diazepam (0.2 mg/kg) as pre-anaesthetic medication was carried out in a double-blind between-patient placebo-controlled trial in 200 children. The assessment of the drugs as pre-anesthetic medication was made by comparing the sedative effect before induction, the status of the patient at induction and the patient's behaviour in the recovery room. All the active drugs were superior to the placebo at induction of anaesthesia. Postoperatively the sedative effect of the high dose of pentazocine was superior to that of the other active drugs, presumably due to the strong analgesic effect at this dose. The rate of respiration was clearly lower after pentazocine than after the other two active drugs. Other side effects or complications did not differ between the groups. It is concluded that, in spite of its favourable sedative effect, a high dose of pentazocine should be used with caution in pediatric premedication because of the possibility of slight respiratory depression.
