A laboratory incubation experiment was performed to study the effects of three trophic level sediments with different nutrition status on the growth including physiological characteristics of Potamogeton crispus by embedding and suspension cultivation ways. The results showed: The high trophic level (HC) sediment was favorable for the early growth and the photosynthesis of Potamogeton crispus but unfavorable for the growth of roots. During the experiment, the POD activity rapidly increased to a maximum value under highly nutritious substrate in embedding groups. Later in the experiment, the content of soluble protein and chlorophyll decreased in the embedding group with HC sediments. To some extent, the normal growth of Potamogeton crispus was inhibited, while there wasn’t an apparente phenomenon that the decline of Potamogeton crispus.

Some information on the size and density of voids that develop in several high purity metals and alloys during irradiation with neutrons at elevated temperatures has been reported as a function of irradiation parameters. An area of particular interest is the nucleation and early growth stage of voids. It is the purpose of this paper to describe the microstructure in high purity nickel after irradiation to a very low but constant neutron exposure at three different temperatures.Annealed specimens of 99-997% pure nickel in the form of foils 75μ thick were irradiated in a capsule to a total fluence of 2.2 × 1019 n/cm2 (E > 1.0 MeV). The capsule consisted of three temperature zones maintained by heaters and monitored by thermocouples at 350, 400, and 450°C, respectively. The temperature was automatically dropped to 60°C while the reactor was down.

In line with the times demand, nationlism changes as a dynamic of dialectics proceeds with changes in social, political, and ekonomic in the country and global levels. Based on a review of historical chronology, this paper analyzed descriptively the relationship between Islam and nationalism in Indonesia. Since the early growth of nationalism and the Dutch colonization period in Indonesia, Islam became the spirit of sacrifice of lives and property of the Indonesian people's fighting to get independence and on the Japanese colonial period and the early days of independence, Islam through the muslim leaders founction as base of departure and developer awareness of nasionalism, patriotism and unity to defend the independence. Despite the authoritarian New Order ruler cope with Islam through the establishment of the Association of Indonesian Muslim Intellectuals (ICMI), but awareness of national Muslim leaders to build Indonesia managed to push governance reforms. And in this era of reform, the spirit of nationalism and the spirit of sacrifice of the Indonesian leaders increasingly eroded by corruption. Key words: proto-nationalism, political nationalism, cultural nationalism.
