    中国摇滚乐诞生于1986年崔健的《一无所有》,迄今已经历了将近三十年的发展。一直以来,作为来自地下的摇滚乐,始终以一种独立的姿态自生自灭。而由于主流媒体的侧重负面性的宣传报道,以及作为小众音乐形式的不被了解,摇滚乐始终处于主流文化的边缘,公众对于摇滚乐的认知也较多地偏向负面性,而热爱摇滚乐的乐迷们,也被看作是具有破坏性的不良年轻群体等。鉴于这种刻板印象,摇滚乐不能被较好地理解,更不能被较好地接纳。但事实上,公众并没有真正深入地去认识这一音乐形式,了解这一群体。 本研究主要运用质的研究中的扎根理论研究方法。研究之初,笔者一共访谈到二十位来自全国各地的乐迷,让他们真实地表达与摇滚乐有关的诸多想法...Chinese rock music has experienced twenty-nine years development since the song called Yi Wu Suo You by Cui Jian in 1986. As a kind of underground music, Chinese rock music grows with the attitude of independence. Because of the reports which emphasize much on the negative aspects of rock music by the major media as well as the small music style rock music itself, Chinese rock music has always sta...学位:新闻与传播硕士院系专业:新闻传播学院_新闻与传播硕士学号:1052013115308

    用偏光显微术、平均折射率法和富立叶红外光谱法研究了壳聚糖的溶致液晶行为。在二氯乙酸、甲酸、丙烯酸和36%乙酸等溶剂中测得的临界浓度都是8%(体积比)或4%~6%(重量比),与根据Flory理论得到的计算值相符。低的临界浓度值表明壳聚糖的链刚性比纤维素的大

    随着海峡两岸经济融合发展,一个新的海峡经济增长极渐渐浮出。在福建省建立知识产权的交易平台是实现海峡两岸知识产权贸易、许可、融资和技术转移的基础,有助于实现海峡两岸经济对接,实现海峡西岸经济发展方式的转变。海峡两岸知识产权交易平台的运行模式应当是政府支持下的自主运行模式,吸收台湾地区的管理经验和资金,并针对福建省的实际和海峡两岸知识产权交易发展趋势进行组织构架和职能安排。福建省教育厅2011年度A类社会科学研究项目“福建制造业发展的知识产权环境完善研究”(JA11006S)成果之

    利用重叠PCR技术将PTH(parathyroidhormone,甲状旁腺激素)基因与TFN(transferrinN_terminalhalf_molecule,转铁蛋白N端半分子)基因在体外融合,融合基因克隆至真核表达载体pPIC9中,转化毕赤酵母GS115。转化子经甲醇诱导后,融合蛋白得到了表达并分泌到发酵上清液中。经SPSepharoseFF阳离子交换层析、PhenylSepharoseFastFlow疏水层析纯化获得了纯度大于95%的PTH_TFN样品。Westernblot分析及腺苷酸环化酶实验证明融合蛋白中的PTH具有与抗PTH抗体结合能力及刺激腺苷酸环化酶的活性,铁饱和实验证明融合蛋白中的TFN和单独的TFN具有相同铁结合能力。因而TFN可望作为PTH的天然运输载体。The fused gene (PTH_TFN) of parathyroid hormone (PTH) gene and transferring N_terminal half_molecule (TFN) gene was amplified by multiple PCR and inserted into pPIC9 vector. The recombinant plasmid pPIC9_PTH_TFN was transformed into Pichia pastoris GS115 by PEG. After methanol induction, the target protein was expressed in fermentation supernatant at high level.The fused protein PTH_TFN with purity being higher than 95% was finally obtained after purification through two_step chromatography : SP Sepharose Fast Flow and Phenyl Sepharose Fast Flow.Western blot analysis and adenylate cyclase assay proved that the fused protein exhibited the bioactivity to stimulate cAMP synthesis and the ability to bind Fe ~3+ in the Fe ~3+ saturation study as the recombinant TFN did indicating that TFN could be used as the transcellar carrier of PTH.国家高技术研究与发展项目基金资助(No.2004AA215172)。~

    Changes of temperature and bio-optical properties in the South China Sea in response to Typhoon Lingling, 2001

    Get PDF
    A large patch of enhanced chlorophyll a concentration (Chla), lower sea surface temperature (SST), and lower sea surface height (SSH) was revealed in the central South China Sea (SCS) in November 2001 after the passage of typhoon Lingling. Maximum SST reduction of 11 degrees C occurred one day after Lingling's passage on 11/11. Subsequently, against a background level of 0.08 mg/m(3), average Chla within the area of 12.60-16.49 degrees N, 112.17-117.05 degrees E increased to 0.14 mg/m(3) on 11/12 and then to 0.37 mg/m(3) on 11/14. Dissolved organic matter and detritus were differentiated from Chla using a recent bio-optical algorithm. They contributed 64% to the increase of total absorption immediately after Lingling, while most of the changes later (74%) were due to phytoplankton. The area under Lingling's impact covered ca. 3 degrees latitude and 4 degrees longitude, which is much greater than the two summer cases previously observed in the northern SCS. This event lasted for ca. 15 days, and resulted in carbon fixation in the order of 0.4 Mt. Such a drastic response was attributed to the coupling of typhoon-induced nutrient pumping with the pre-established cyclonic gyre in the central SCS driven by the prevailing northeast monsoon
