The marine environment includes the nutrient-rich coastal waters, relatively nutrient-poor open oceanic waters, coral reef
atolls, metal-rich hydrothermal vent fluids with temperatures of 200–350°C, cold-seeps, estuaries, mangrove swamps, intertidal
beaches and rocky shores. Oceans are home to some of themost diverse and unique life forms. This article is an attempt to
introduce some of the fundamentals of biologicaloceanography andmarine biologyto describe life in the sea. 相似文献

Health sciences librarians have historically viewed disseminating information to health professionals as a major role. Typically, they have provided individualized services and are among the professions that help health professionals further their education after finishing formal education. Another group directly involved in health professional continuing education is continuing education (CE) providers who offer ongoing learning through group activities. These two professions often reached the same audiences in the past, and their different approaches--individual and group--were complementary. Health professionals who needed information immediately or who wished individual learning used the library while those who wanted to hear eminent colleagues tended to use CE meetings or seminars; some did both. The librarians and CE providers rarely interacted, but this is now changing. With the introduction of personal computers, medical librarians have expanded their responsibilities to include formalized classroom instruction. At the same time, CE providers have increased their scope beyond formalized group instruction into individualized education. Librarians and CE providers can either collaborate and share their expertise or they can compete against each other. 相似文献

Recorded are some biographical data about the late professor Freudenthal along with some indications about his mathematical work. In an appendix a tiny part of his mathematical work which can be explained in a fairly direct manner is discussed.This is the somewhat modified text of a commemorative address given at the annual meeting of the Wiskundig Genootschap, the Dutch mathematical society, on April 5, 1991, cf. Nieuw Archief voor Wiskunde, 9 (1991), 131–136. 相似文献
