國立臺灣海洋大學 水產養殖學系 陳建初、鄭學淵所指導 崔文經的 鉛對黃鰭鯛生理反應研究 (2017),提出Neptune dao關鍵因素是什麼,來自於黃鰭鯛、鉛、組織、蓄積、鹽度、半致死濃度、金屬硫蛋白、生化指標。

而第二篇論文國立中正大學 戰略暨國際事務研究所 林泰和所指導 尤柏涵的 中國海權擴張與中日安全困境兼論美日同盟之調整 (2015),提出因為有 海權、安全困境、再平衡、美日同盟的重點而找出了 Neptune dao的解答。

鉛對黃鰭鯛生理反應研究

為了解決Neptune dao的問題,作者崔文經 這樣論述:

  本論文研究目的為探討黃鰭鯛(Acanthopagrus latus)在不同鹽度、鉛離子環境變化下之半致死濃度(LC50),同時分析體內鉛蓄積、金屬硫蛋白表現量、生化指標變動之影響。  黃鰭鯛魚苗(1.41 ± 0.48 g)在不同鉛離子濃度與鹽度(0、9、17、25及34‰)環境變化中之半致死濃度(LC50)以鹽度17‰時魚體內含鉛(Pb)量最高,在曝露96小時後於鹽度0、9、17、25及34‰下,LC50分別為0.33、1.43、3.78、2.32及1.46 mg Pb2+/l。此外,在鹽度17‰環境下,經過6、12、24、48及96小時後LC50分別為124.67、33.02、10.

40、5.15及3.78 mg Pb2+/l。  黃鰭鯛幼魚(8.67 ± 1.75 g)曝露於鹽度34‰、鉛濃度1、2及5 mg Pb2+/l海水中,經過1、2、3、5及7天後,組織中鉛含量由高至低分別為腸>鰓>肝臟>骨頭>肌肉。因此,當黃鰭鯛幼魚蓄養在海水中,腸道是最主要鉛蓄積組織。  黃鰭鯛在不同鹽度及鉛濃度34‰下對各組織金屬硫蛋白(meta- llothionein, MT)表現量研究:黃鰭鯛曝露在重金屬鉛濃度1、2及5 mg Pb2+/l組合下,經過0、1、2、5及10天後,各組織MT表現量皆隨水體鉛濃度、曝露天數增加而增加(p < 0.05)。各組織測值變動隨組織不同而有所差異,

組織中MT表現量由高至低分別為腸>肝臟>鰓。  不同重金屬鉛離子(Pb2+)濃度下對黃鰭鯛血液生化指標之影響:黃鰭鯛在鹽度34‰人工海水中,分別曝露於1、2及5 mg Pb2+/l三種鉛濃度溶液中,經過1、2、5及10天後魚體血清中膽固醇含量在第2天達到最高值,第10天降到最低值。血清轉胺酵素(GOT、GPT)、血糖(glucose, Glu)、乳酸(lactate,Lac)皆隨曝露天數增加而增加(p < 0.05)。

中國海權擴張與中日安全困境兼論美日同盟之調整

為了解決Neptune dao的問題,作者尤柏涵 這樣論述:

China’s military development has rapidly grown due to its stable economic growth since 1990s. Along with China’s double-digit growth in military spending, China’s navy, the People’s Liberalization Army Navy has been rapidly growing and been transformed its strategic guidelines with ambition to

pursue China’s sea power. However, China’s sea power expansion has made Japan insecure and suspicious of China’s intentions of sea power expansion. Therefore, Japan and the U.S. set out to strengthen and broaden the U.S.-Japan alliance to balance China’s sea power expansion under framework of rebala

nce to Asia-Pacific. The framework of study is mainly consisted of three sections. The first section is to analyze development of China’s sea power including the background of China’s awakening of sea power, the features of China’s naval strategy, China’s intentions of sea power expansion, its cu

rrent situation of naval modernization and capabilities. The second section is to analyze how China’s sea power expansion caused Japan’s insecurity that made Japan adopt measures and balancing policy. In the third section, the U.S.-Japan alliance has strengthened as the U.S. and Japan committed to e

ach other. The findings of study show that China’s sea power expansion is necessary to maintain its national development and protect its national interests. However, China’s rapid growth in sea power has made Japan insecure. Japan responds to China with the balancing policy and the increase of mi

litary capabilities. Thus, the security dilemma between Japan and China has exacerbated. The U.S.-Japan alliance has been strengthened and adjusted under rebalance to Asia-Pacific. As a result, the alliance relation gradually becomes more symmetric, in the meanwhile, Japan becomes more proactive.
