随着缅甸许多地区马铃薯种植面积和产量的增加,但是大多地处热带、亚热带气候区,高温高湿条件不利于马铃薯的长期贮藏。所以本论文的研究内容主要针对当地农民和小规模生产者更好地储存马铃薯,研究一种简单有效的马铃薯脱水技术。以缅甸东枝镇新鲜马铃薯为试验对象,采用热风烘箱干燥机,研究了不同干燥温度和不同漂烫剂对马铃薯干燥特性和品质的影响。烘箱干燥的最佳温度是根据水分含量、水分活性、色差、缩水率、复水率、口感、上染率等因素确定的。干燥温度(60℃、70℃、80℃)和漂白剂(NaMS、NaCl、KMS)的组合表明:(1)在温度60℃、70℃和80℃烘干箱里的NaMS样本中能观察到最低的水分含量,这是由于较高的干燥温度从薯片中蒸发了很多的水分,NaCl、NaMS和KMS处理的漂白剂之间的水分含量没有显著差异。(2)在60℃、70℃和80℃下用NaMS漂白的样本比用KMS和NaCl漂白的样本干得更快。在这种情况下,与其他净化法相比,薯片的干燥速率在120分钟和180分钟(NaMS和80℃)加工净化后达到最高值。(3)在70℃和KMS漂白净化中,得到了薯片的最大复水率(3.55)和最大收缩率(87.16%)。在80℃的NaMS(偏亚硫酸钠)漂白净化处理下,干薯片的水分活度最低(0.62)(表3-1)。在60℃和NaCl(氯化钠)热烫条件下,干马铃薯片的水分活度最高(0.71)。表3-1中的干薯片(80℃温度和NaMS漂烫)中发现的色差最小。(4)80℃是干燥薯片的最佳温度。在此温度下,经过漂白NaMS净化的薯片质量不仅提高了复水率和口感,而且降低了色差和水分活度。因此,漂烫剂与NaMS在80℃下的组合是马铃薯烘干的最佳选择。

Geostatistics belongs to the wide class of statistical methods. It is used and applied to analyze and predict the values associated with spatial or spatio-temporal phenomena such as seismological events. Thus, in addition to its adaptability to perform spatial data analysis based on the principles of variography, many other methods more representative of the spatial distributions of the epicentres have been experimented. The unidirectional or isotropic fractal variogram associates the criterion of variance with the fractal dimension which is a better descriptive parameter of the spatial organization of events. The same analysis procedure carried out through a directional or azimuthal variogram introduces the context of a preferential direction of earthquake evolution. Moreover, b-value is a privileged seismological parameter that can be studied alone or in combination with other more advanced geostatistical analysis factors such as fractals, fractal dimensions and the anisotropic variogram. All these concepts were used as methodology for a protocol of analysis of the catalog of the Algeria seismicity including 1919 events for the period extending from 1673 to 2010. This catalog is provided by the compilation of partial catalogs synthesized by the CRAAG (Research Centre in Astronomy, Astrophysics and Geophysics).

We investigated the effects of fermented nori (Pyropia yezoensis) liquid fertilizers on plant growth, soil plant analysis development (SPAD) values, and nutrient uptake of komatsuna (Brassica rapa L. var. wakana komatsuna) plants. The four types of fermented nori seaweed liquid fertilizers (SLFs) evaluated in this study were prepared by anaerobic fermentation of unwashed nori (SLF1), aerobic fermentation of unwashed nori (SLF2), anaerobic fermentation of washed nori (SLF3), and aerobic fermentation of washed nori (SLF4). In Experiment 1, the highest plant growth, SPAD, and nutrient uptake values were obtained from treatment with SLF2 and SLF4. There were no significant differences between the effects of basal and foliar application of SLFs, except for iodine (I) content;plants treated with SLF1 had the highest I content. In Experiment 2, plant growth and nutrient uptake decreased with higher concentrations of SLFs. Plants treated with 25% SLF2 + 75% chemical fertilizer (CF) or 25% SLF4 + 75% CF exhibited significantly higher plant growth and nutrient uptake. The highest I content resulted from treatment with 75% SLF1 + 25% CF or 100% SLF1. Taken together, our results showed that 25% SLF + 75% CF produced the best plant growth characteristics, nutrient uptake, and I content relative to the controls. Therefore, basal application of these liquid organic fertilizers can be used to increase productivity, nutrient uptake, and I content and to reduce nitrate-nitrogen content in komatsuna production.

As one of the primary business centers of China, Guangzhou has been undergoing rapid growth and expansion. Over the past decade, the Guangzhou Municipality Government has significantly upgraded its transport infrastructure, especially with the highly beneficial expansion of its Subway Mass Rapid Transit(MRT) *** steps have also been taken to continue planning the construction of new roads, a Bus Rapid Transit(BRT)system and other transportation facilities. Further administrative and regulatory measures have also been implemented to control the situation, such as the banning of motorcycles from the central city area and the limitation of new automobile registrations. However, Guangzhou continues to face serious challenges of traffic congestion in and around the city center owing to further intensification of its population with economic growth. The need to ease Guangzhou's stretched public transportation resources,and at the same time to support the realization of its"Eastward Advance" strategy, presents a unique challenge and opportunity to develop an advanced high-efficiency public transportation modality for Guangzhou, viz. the Group Rapid Transit(GRT) involving the use of automation-guided(driverless) smart-vehicles. This paper outlines the PRT/GRT(PRT: Personal Rapid Transit) smart-vehicle modality and also puts forth a proposal of Guangzhou's first GRT route as the city's first dedicated transportation link to the scenic landscape of the Eastern Tourism *** GRT route will help in diffusing the city's traffic congestion as well as support the effectuation of Guangzhou's "Eastern Expansion" strategy, supplementing the ongoing expansion of the Guangzhou Municipality's subway MRT networks.
