学术期刊划分及在期刊管理中的应用

学术期刊是图书馆行业理论探讨和业务实践中经常提到的概念,一般学术期刊是指学术性较强的期刊,是相对于非学术期刊而言的。但学术期刊的完整定义以及它的划定范围相对比较模糊,相关研究只是一语带过,且专门研究学术期刊这一概念的定义、特征、范畴的文献很少。文章专门就学术期刊的概念、划分,以及学术期刊与非学术期刊、学术图书及核心期刊的关系加以论述,并就学术期刊划分在图书馆期刊工作实践中的应用进行探讨。通过对学术期刊特征、范畴的认识和具体的划分,可应用于期刊实践中促进期刊工作效率,提升工作质量

IL-20及其受体在大鼠自身免疫性心肌炎不同阶段的表达

目的探讨IL-20及其受体在大鼠实验性自身免疫性心肌炎(EAM)急慢性期各阶段的表达。方法将提纯精制后的猪心室肌球蛋白加等体积含结核杆菌H37Ra株的完全弗氏佐剂充分混合,于Lewis大鼠双后足皮下注射制作大鼠EAM模型;将15只大鼠按随机数字表法分成3组,每组5只,分别于3、6、12周后处死取心肌组织进行检测。另取5只大鼠注射0.9%氯化钠注射液作为对照组。HE染色评估EAM急慢性期各时点心肌损伤程度;应用实时荧光定量RT-PCR检测IL-20及其受体链(IL-20R1/R2,IL-22R1)在各时点的mRNA表达;应用Western blotting法检测IL-20在各时点的蛋白表达。并以ELISA检测不同时点心肌组织匀浆IL-20蛋白含量[IL-20蛋白/总蛋白(pg/ng)]。结果 IL-20在EAM急性期3周时表达逐渐升高,6周时达峰值,12周时又逐渐减少。IL-20的组织蛋白水平与基因表达相一致。结论 IL-20可能参与大鼠EAM的疾病过程,并且可能在EAM的晚期炎症及慢性心肌纤维化的机制中起重要作用

Fine Root Biomass and Dynamics of Casuarina equisetifolia Plantations on Coastal Sandy Soil

2005年1月到11月对福建省惠安县赤湖林场不同林龄木麻黄人工林细根的生物量及其动态特征进行了研究.结果表明,24a生木麻黄林细根生物量分别占其地下部分生物量和林分总生物量的53.1%和3.8%;活细根的生物量随林龄的增大而逐渐增加,至30a林龄时达到最大值12.373thm-2,而后逐渐下降,死细根的生物量则呈现一直增大的趋势,木麻黄人工林细根的生物量与林分地上部分的生长具有显著的相关关系;细根生物量具有明显的季节动态,各林龄无论活细根还是死细根都表现为双峰型,3a生和18a生的活细根出现在1月和7月,而12a生出现在3月和7月,对于死细根,12a生和18a生的两个峰值出现在3月和7月,5a生则出现在7月和11月.各林龄木麻黄防护林活、死细根密度垂直分布呈单峰型,最大值出现在表层的0~10cm土层中,后随土层厚度增加逐渐减少,其中5a林龄细根生物量随土层深度增加而减少表现最为明显.在0~10cm土层中的活、死细根生物量分别占全部活细根生物量的51.9%和死细根生物量的53.3%,活细根生物量的84.6%和死细根生物量的82.8%分布在0~30cm的土层中.以后随着林龄的增加,表层土壤中细根生物量的比重降低而深层的比重增加.图3表2参31Fine root biomass and its dynamic characteristics of different aged Casuarina equisetifolia plantations on coastal sandy soil were studied in the Chifu Forestry Farm of Huian County, Fujian. The results showed that the fine roots of 24-year-old plantation accounted for 53.1% of the total underground biomass and 3.8% of the total amount of plantation, respectively; the standing crop of living fine roots increased as the forest aging until its maximum reached 12.373 t hm-2 at 30-year-old, then decreased gradually, while the biomass of dead fine roots increased all along as the forest aging. The fine roots biomass had remarkable correlation with the growth of the above-ground. The fine roots biomass was found with remarkable seasonal dynamics that the standing crop of living and dead fine roots of different aged plantations both were shown with double peaks, while the maximum occurred in different seasons for different aged plantations. The maximum of living fine roots of 5-and 18-year-old plantations occurred separately in January and July, while those of 12-year in March and July. As to the dead fine roots, those of 12-and 18-year occurred in March and July, and 5-year in July and November. The vertical distribution of living and dead fine roots at soil depth was shown with single peak for C. equisetifolia plantations, being concentrated at 0~10 cm, and then decreased with depth gradually. This trend was obvious for 5-year-old plantation. The biomasses of living and dead fine roots at 0~10 cm accounted for 51.9% and 53.3% of the totals, respectively. The 84.6% of living and 82.8% of dead fine roots concentrated at the depth of 0~30 cm. The proportion of fine roots decreased in topsoil and increased in deep soil along with aging of the forest.
