| 3 | Variety-specific responses of lettuce grown in. a gravel-film technique closed hydroponic system to N supply on yield, morphology, phytochemicals, mineral content and safety显示文摘Utilization of nitrogen(N) element is a common practice used to reach profitable yields in horticultural crops and N supply can be used as a tool to manipulate the enhancement of phytochemicals and minerals in vegetable crops to address consumeroriented quality production. Hence the study was aimed to investigate the effect of N application on leaf morphology, ascorbic acid content, phenolic acids, flavonoids, mineral content, and nitrate residues in three lettuce varieties(two green leafy lettuce, Multigreen 1 and Multigreen 3; one red leafy lettuce, Multired 4) grown in a closed hydroponic system(gravel-film) at harvest. Nitrogen was applied as ammonium nitrate(NH_4 NO_3) at six different concentrations of 0, 60, 90, 120, 150 and 180 mg L^(–1). The results obtained during 2015 and 2016 seasons were similar and demonstrated variety dependent responses with respect to different N application rates. Multigreen 3 was more sensitive to N supply and showed higher amount of nitrate residue at harvest. Variety Multired 4 was less sensitive to N supply followed by Multigreen 1. Although N supply at 120 mg L^(–1) improved the yield and the number of leaves in Multigreen 3, overall 90 mg L^(–1) can be recommended for these lettuce varieties to improve the yield and the accumulation of ascorbic acid content, phenolic acids mainly caffeic, caftaric acids, quercetin(the important flavonoid in lettuce), and Fe and Mn contents. Furthermore, the concentration of 90 mg L^(–1) improved the antioxidant property(FRAP and ABTS^+) and reduced the nitrate accumulation, ensuring safe food for consumers. | Bevly M. Mampholo Martin M.

| 6 | Lunar surface mineralogy using hyperspectral data: Implications for primordial crust in the Earth-Moon system显示文摘Mineralogy of the Lunar surface provides important clues for understanding the composition and evolution of the primordial crust in the Earth-Moon system.The primary rock forming minerals on the Moon such as pyroxene,olivine and plagioclase are potential tools to evaluate the Lunar Magma Ocean(LMO) hypothesis.Here we use the data from Moon Mineralogy Mapper(M^3) onboard the Chandrayaan-1 project of India,which provides Visible/Near Infra Red(NIR) spectral data(hyperspectral data) of the Lunar surface to gain insights on the surface mineralogy.Band shaping and spectral profiling methods are used for identifying minerals in five sites:the Moscoviense basin,Orientate basin,Apollo basin,Wegener crater-highland,and Hertzsprung basin.The common presence of plagioclase in these sites is in conformity with the anorthositic composition of the Lunar crust.Pyroxenes,olivine and Fe-Mg-spinel from the sample sites indicate the presence of gabbroic and basaltic components.The compositional difference in pyroxenes suggests magmatic differentiation on the Lunar surface.Olivine contains OH/H_2O band,indicating hydrous phase in the primordial magmas. | V.

| 7 | 超声波辅助制革生产植物鞣制中的扩散过程显示文摘植物鞣制是一种使用天然材料并使皮革具有多种功能的鞣制方法。这种鞣制方法的缺点在于植物鞣剂(VTA)穿透皮基体需要很长时间。因此,有必要通过应用超声波等手段使这种传统的生态友好鞣制方法转变为制革人员喜欢的高效鞣制方法。本研究是有关超声波影响植物鞣制工艺的。研究了加工时间、超声波功率以及预鞣处理等重要过程参数对于植物鞣剂吸收率的影响。同时还研究了超声波功率对于成革收缩温度的影响。研究结果表明应用超声波能够显著加速植物鞣制过程。当应用120W~210W超声波时,植物鞣剂的吸收率约增加30%-40%。为了弄清楚超声波加速植物鞣制过程的机理,研究了预超声波处理对于基体(皮)以及鞣剂(VTA)的影响。在鞣制工序前的超声波预处理能明显降低植物鞣剂的尺寸从而促进鞣剂的渗透。从实验数据中计算得到的应用指定条件的超声波时,植物鞣剂的扩散系数(D)增加了1倍(D:2.64×10^-5cm^2/sec)。因此,在植物鞣制过程中应用超声波能够改进扩散速率从而明显节省加工时间并提高成革质量。这种鞣制方法能够方便地在常规划槽或鞣制系统中实现大规模加工。因此,这种新技术在不久的将来是可行的。 | V.
