Study on Risk Management of Investment on Food and Drug Safety of Fiddlehead
Fiddlehead has been used in traditional Chinese medicine since Han Dynasty. However fiddlehead are still underutilized and hence wasted. In order to better utilize fiddlehead resources, the drug safety of benzene/alcohol extractives from fiddlehead were analyzed by GC/MS. Relative content of each component was determined by area normalization. The main ingredients of benzene/alcohol extractives of fiddlehead were toluene,2-furancarboxaldehyde, 5-(hydroxym ethyl)-, n1-(4-hydroxybutyl)-n3-methylguani dine acetate, 1,3-dihydroxyacetone dimer, sulfurous acid, cyclohexylmethyl hexadecyl ester, 1,4,7,10,13,16-hexaoxanonadecane, 18-propyl-, 1,6-anhydro-.beta.-d-glucopyranose(levoglucosan), oxirane, hexadecyl-, etc. The results obtained fully indicated that the benzene/alcohol extractives of fiddlehead had the great potential of noble natural biomedicines.
Study on Appropriate Growth Conditions and Cropping Patterns of Pteridium aquilinum
采用塑料大棚、小拱棚、露地栽培3种种植模式,研究了不同种植模式对蕨菜生长环境条件、生长发育和产量的影响.结果表明:蕨菜适宜的出芽气温和地温分别为13～14℃和11～12℃;适宜的出茎气温和地温分别为15～16℃和12～14℃;适宜的孢子形成气温和地温分别为26～27℃和20～22℃.塑料大棚促进蕨菜提前出芽、出茎,采收期较其他模式提前25～39 d,产量达20 800 kg/hm2,分别比小拱棚和露地增产25%和40%.
Protection of the Marine Environment: The International and National Regulation of Deep Seabed Mining Activities
This chapter provides an overview of the international and national regulatory framework pertaining to deep seabed mining activities. It begins by discussing the UN Convention on the Law of the Sea, the backdrop for all marine activities – be they national or international – and examines the obligations of states to protect the marine environment from the harmful effects arising from deep seabed mining. Next, the chapter examines the international regime for deep seabed mining (i.e. “activities in the Area”), explaining the “common heritage of mankind” status of the Area (i.e. the international seabed); the functions of the International Seabed Authority (ISA), the international organization established to govern deep seabed mining in the Area; and the concept of state sponsorship of non-state entities (i.e. private actors) for deep seabed mining in the Area. The chapter follows with a discussion of the development of national legislation to regulate deep seabed mining, examining efforts in the Pacific region where many prospective deep-sea mining sites are located. This includes a look at the legislative regimes of several Pacific Island nations, namely, Papua New Guinea, Tonga and the Cook Islands, for whom deep seabed mining may soon become a reality – as well as New Zealand and Japan, countries with comparatively developed rule of law and legislative regimes that have undertaken or considered deep seabed mining in their national waters. Overall, the chapter critically describes and evaluates the current regulatory status in the international and national seabed areas and highlights some salient gaps that require urgent attention in order to ensure marine environmental protection and mitigate impacts on humans.
