不同木豆品种耐铝性的基因型差异及其机理研究

以6个品种的木豆为材料，探讨了木豆品种间耐铝性的基因型差异及其机制。铝对根伸长的抑制大小及苏木精对根尖的染色模式的研究结果表明，不同品种木豆的耐铝性基因型差异明显。在铝胁迫条件下，去除根尖吸附的粘胶，耐铝的基因型MD2和敏感的基因型MD5根的伸长率均减少，而根尖被苏木精染色程度加深；去除粘胶对MD2的影响大于MD5，说明粘胶对根尖的保护是木豆抵御铝毒的一个重要机制。虽然铝胁迫可诱导木豆根系分泌柠檬酸和苹果酸，但根系苹果酸的分泌量在MD2和MD间无显著差异，MD2柠檬酸的分泌量甚至低于MD5。     

UV／H2O2／GAC与GAC处理微污染水的研究

文章进行了UV／H2O2／GAC和GAC系统用于微污染水深度处理的试验研究,结果表明：UV／H2O2／GAC对uV篮;和TOC均有良好的去除效果,当H2O2投量3．0mg／L,UV／H2O2反应器停留时间20min时,系统的COD和UV254去除率为44．6％和72．8％。UV／H2O2主要作用在于改善了GAC对有机物的吸附,产生了羟基自由基,从而提高了去除效果。

NiOγ／-Al2O3反应吸附苯并噻吩

以等体积浸渍法制备了负载型NiOγ／-Al2O3吸附剂,在固定床反应装置上对含苯并噻吩的模型化合物进行反应吸附脱硫实验,考察了NiO负载量、模型化合物硫含量及活性组分的形态对吸附剂脱硫性能的影响,并用XRD、SEM—EDS分析、XPS分析对载体和吸附剂进行了表征。实验结果表明：NiOγ／-Al2O3吸附剂具有较高的穿透硫容,能有效脱除模型化合物中的苯并噻吩;反应过程中生成了NiS;C的沉积以及Ni的硫化物的生成导致了吸附剂的失活。     

Being watched over by a conversation robot may enhance safety in simulated driving

IntroductionIn an aging society that is more and more information-oriented, being able to replace human passengers’ protective effects on vehicle drivers with those of social robots is both essential and promising. However, the effects of a social robot’s presence on drivers have not yet been fully explored. Thus, using a driving simulator and a conversation robot, this experimental study had two main goals: (a) to find out whether social robots’ anthropomorphic qualities (i.e., not the practical information the robot provides drivers) have protective effects by promoting attentive driving and alleviating crash risks; and (b) by what psychological processes such effects emerge. Method: Participants were recruited from young (n = 38), the middle-aged (n = 39), and the elderly (n = 49) age groups. They were assigned to either the treatment group (simulated driving in a conversation robot’s presence) or the control group (simulated driving alone), and their driving performance was measured. Mental states (peaceful, concentrating, and reflective) also were assessed in a post-driving questionnaire using our original scales. Results: Although the group of older participants did not experience protective effects (perhaps due to motion sickness), the young participants drove attentively, with the robot enhancing peace of mind. The protective effect was also observed among the middle-aged participants, and the verbal data analysis ascribed this to the robot’s role of expressing sympathy, especially when the middle-aged drivers nearly had not-at-fault crashes, which caused them to be stressed. In conclusion, we discuss the practical implications of the results.     

Surface solar ultraviolet radiation: A theoretical approach of the SUVR reaching the ground in Athens, Greece

Daily total ozone observations made during 1985–1993 by both the Total Ozone Mapping Spectrometer (TOMS) flown on the Satellite Nimbus-7 and the Dobson Spectrophotometer have been used in order to investigate the fluctuations of the daily broad-band and spectral solar ultraviolet radiation reaching the ground. This investigation has been performed by employing a recently developed parametric algorithm for the estimation of the spectral and broad-band solar ultraviolet radiation which takes the total ozone variations into consideration. Total ozone reductions during the summertime from 1985 to 1993 over Athens, Greece (37.6° N, 23.4° E), cause an increase in the ultraviolet irradiance which reaches the ground of 0.54 %, 0.98 %, 2.60 % and 0.79 % per decade for the months of July at 300 nm, 312 nm, 320 nm and UVB (280-320 nm), respectively.
