“巴伦比”发酵型无核黄皮果醋的研制

以广东云浮郁南县优质成熟无核黄皮为原料,加入植物提取用酶控温酶解,然后加入葡萄酒酿酒酵母、多微麸曲、活性醋酸菌和玉米芯进行酒精发酵与醋酸发酵同步进行,最后降低温度加入皂土陈酿后过滤,即得到保健功效好的“巴伦比”无核黄皮果醋。该无核黄皮果醋呈棕黄色,具有无核黄皮特有的果香和浓郁的醋酒香,酸味纯正柔和、口味微甘爽口,稳定性好。     

What Happened to Ecology? John McHale and the Bucky Fuller Revival

Since the early 20th century, the environmental impulse in architecture has waxed and waned. Anthony Vidler considers this cyclical phenomenon, particularly in relation to the Independent Group in Britain during the 1950s, which culminated in John McHale's discovery of Richard Buckminster Fuller in 1955 and the full-blown Bucky Fuller revival of the 1960s.

The influence of seed weight on the development and growth of berries and live green ovaries in Vitis vinifera L. cvs. Pinot Noir and Cabernet Sauvignon

Background and Aims:  Variation in berry size is observed at harvest. Although the growth of seeded berries has been described, no such data are reported for seedless berries or live green ovaries that occur in wine cultivars. This study describes the growth of individual berries in relation to seed development.
Methods and Results:  Regular measurements of berry diameter described the growth of Pinot Noir and Cabernet Sauvignon. Seeded berries had typical double sigmoid growth curves, whereas seedless berries, which developed more slowly from midway through Phase I, continued to grow in Phase III if a seed trace was present. Berries without a seed trace did not enlarge after Phase II. Live green ovaries failed to grow after a small initial expansion post-cap fall.
Conclusion:  Seeded berries had double sigmoid growth as a result of cell division and expansion, whereas the growth of seedless berries and live green ovaries was the result of cell expansion alone. Seed development is necessary for cell division within the mesocarp.
Significance of the Study:  Seed development is essential for the full development of Pinot Noir and Cabernet Sauvignon berries. The data suggest that divergence of berry development from a characteristic growth curve may be linked to the extent of seed development.     

水分胁迫下肥料配比对葡萄光合速率与氮代谢的影响--测试文章

以无核白鸡心葡萄为试材，设置3个水平的水分处理和3个肥料配比，研究水分胁迫下肥料配比对无核白鸡心葡萄叶片叶面积、叶绿素含量、光合速率及氮代谢相关酶活性的影响。结果表明：萌芽期和坐果期土壤水分含量为田间持水量的55%～60%、施肥配比为N∶P∶K=2∶5∶3的水肥处理能有效促进叶面积增加，提高光合速率，是较好的水肥处理组合；转色期和采收后需维持正常含水量和适当增施钾肥可提高光合速率；土壤水分含量为田间持水量的55%～60%、施肥配比为N∶P∶K=2∶5∶3的水肥处理无核白鸡心葡萄硝酸还原酶活性较高，能有效促进氮肥的吸收利用；水分胁迫处理使谷氨酰胺合成酶活性先升高后降低，且使谷丙转氨酶活性升高。在生长期中轻度水分胁迫、适当增施钾肥能明显提高硝酸还原酶、谷氨酰胺合成酶与谷丙转氨酶活性，提高氮肥的转化利用。     

Differentiation in Vital Practice: An Analysis Using RMIT University of Technology and Design Interfaces With Architects

One of the most influential figures in architectural education and practice today, Leon van Schaik , Professor of Architecture (Chair of Innovation) at RMIT in Melbourne, has dedicated the last two decades of his career to the promotion of local and international architectural culture through design practice research and the commissioning of building. Here he describes how he has nurtured a research-oriented approach through his engagement with a network of ‘vital’ practitioners worldwide who are interested in strong ideas and pushing the questioning of the status quo.     

任意截面导体柱的电磁散射数值解

卡门翼形和任意多边形是两种典型的不规则形体，由于其不规则曲边和尖锐的角点，它们的电磁散射问题给传统的FDTD数值求解造成了一定的困难，这是因为要获得较高的精度，必须细分网格，从而增加内存需求和计算时间，本文利用形体变换结合时域有限差分法的Thompson-FDTD方法对这两种典型的不利形体的散射问题进行了数值模拟，其结果进一步验证了Thompson-FDTD方法对散射体几何形状变化具有较强的适应能力和较高的数值精度。     

Thompson-FDTD方法中的两步法

本文将流体力学领域的微分-Thompson变换与时域有限差分(FDTD)技术结合起来,所形成的Thompson-FDTD方法,首次用来计算和分析任意形状介质体的电磁散射特性。该方法至少具有两个明显的优点:可以把不规则形体变换成规则形体,有利于精确匹配边界条件;可以任意调配网格分布,有利于提高计算精度。其数值实现进一步证实了该方法能精确模拟任意形状介质目标的电磁散射过程。     

电子束辐照对无核葡萄干的杀灭霉菌效果及感官品质的影响

为有效控制无核葡萄干的霉菌,采用2、4、6、8、10 kGy的电子束对无核葡萄干进行辐照处理。同时,根据相关的标准,以色泽(权重为30%)、滋味(权重为35%)、气味(权重为35%)为评价指标,制订无核葡萄干的感官评价标准,并按此标准对辐照处理后的无核葡萄干进行感官品质评价。结果表明:经2 kGy辐照的样品感官评价结果与对照组无明显差异;经4、6、8、10 kGy辐照的样品感官评价结果低于对照组;无核葡萄干经6 kGy辐照,可杀灭100%的霉菌。     

热风干燥温度对无核白葡萄干品质的影响

为了研究不同热风温度对葡萄品质的影响,以新疆吐鲁番无核白葡萄为材料,经促干剂处理后,分别在30,35,40,45℃条件下进行热风干燥。结果表明:在干燥无核白葡萄过程中,葡萄中的抗坏血酸、可滴定酸、总酚含量下降,而褐变度上升。综合比较可知,40℃热风干燥制得的葡萄干品质较好。
