为了提高对番茄表面农药残留量的准确检测能力,提出一种基于视觉图像识别的番茄表面农药残留量无损检测方法。采用激光成像技术进行番茄表面农药残留区域视觉图像采集,对采集的番茄表面图像进行农药残留量的光谱特征分析,提取番茄表面农药残留区域的边缘轮廓特征,根据特征提取结果进行番茄表面农药残留区域视觉图像重构,在重构的区域图像中采用分块匹配技术进行番茄表面农药残留量区域分割,结合自适应分块特征匹配方法实现番茄表面农药残留量检测识别。仿真结果表明,采用该方法进行番茄表面农药残留量的无损性较好,输出图像的信息饱和度较高,提高了对番茄表面农药残留量的准确检测能力,在番茄病虫害防治和农药的去除等方面具有很好的应用价值。 相似文献

The main objectives of the experiment were: 1) to compare bacterial populations of mastitis-causing organisms on the teats of lactating dairy cattle housed on sand and sawdust bedding and, 2) to examine the relationship between bacterial counts present in the 2 bedding types with those on teat ends. Sixteen lactating Holstein cows were housed on either sand or sawdust-bedded free stalls using a crossover design with 3 wk per bedding type. Bedding samples were collected on d 0 (prior to animals lying on the bedding), 1, 2, and 6. Teat ends were sampled prior to the morning milking on d 1, 2, and 6. All samples were analyzed to determine coliform, Klebsiella spp., and Streptococcus spp. populations. There were 2 times more coliforms and 6 times more Klebsiella bacteria on teat ends of cows housed on sawdust compared with those housed on sand. In contrast, there were 10 times more Streptococcus spp. bacteria on teat ends of cows when housed on sand compared with sawdust. In both sawdust and sand bedding, coliforms, Klebsiella and Streptococcus counts increased over each experimental week, although patterns varied with bedding and bacteria type. Bacterial counts on teat ends were correlated with bacterial counts in sawdust (r = 0.47, 0.69, and 0.60 for coliforms, Klebsiella spp., and streptococci, respectively) and in sand (r = 0.35 for coliforms and r = 0.40 for Klebsiella spp.). In conclusion, coliforms and Klebsiella spp. on teat ends were more numerous when cows were housed on sawdust bedding, but Streptococcus spp. were more numerous on teat ends of cows housed on sand. 相似文献

The toluene-degrading bacterium Acinetobacter sp. Tol 5 is highly adhesive through cell-surface nanofibers. Previously, we identified two morphologically distinct nanofibers on Tol 5 cells, namely, nonperitrichate anchor-like and peritrichate pilus-like nanofibers. In the present study, the application of improved electron microscopy techniques enabled discrimination of three distinct types of peritrichate nanofibers on Tol 5 cells. Interestingly, production of these nanofibers was affected by the available growth substrate. Thick, long, straight nanofibers a, which were present on cells grown on toluene, lactate, and ethanol, were not observed on cells grown on triacylglycerol (TAG). In contrast, cells grown on TAG were covered with long, curved nanofibers c, which only existed sparsely on cells grown on toluene, lactate, and ethanol. Thin, short, straight nanofibers b were found densely covering the margin of cells grown on all four growth substrates. SDS-PAGE of Tol 5 cell-surface proteins detected a protein of 17.5 kDa that was expressed at a high level on ethanol, but was undetectable on TAG. Conversely, a 26 kDa protein was identified that was exclusively expressed on TAG, but was only faintly expressed by cells grown on the other substrates. Based on N-terminal amino acid sequences, the 17.5 and 26 kDa proteins were identified as the major subunits of type 1 and Fil pili, respectively, which are typical bacterionanofibers. From these results, we deduced that nanofibers a and c are type 1 and Fil pili, respectively. The adhesiveness of Tol 5 cells was low only when they were grown on TAG. 相似文献

在研究分散染料对涤纶/氨纶双组分染色上染规律的基础上,研究了助剂对该染色系统的影响。研究发现,助剂的加入对分散染料的上染分配有不同程度的影响,并随着助剂品种的不同而有所不同。某些非离子表面活性剂能使分散染料对氨纶组分的上染增加;阴离子表面活性剂一般能降低分散染料对氨纶组分的上染;聚乙二醇化合物几乎不影响上染分配。 相似文献

Two isolates each of Fusarium moniliforme and Fusarium proliferatum isolated from maize were compared for growth and fumonisin B1 production on maize, wheat, and barley extract agars and on irradiated maize, wheat, and barley grain in relation to water availability and temperature. Growth rates of both Fusarium spp. were similar or higher on wheat and barley than on maize extract agar. Regardless of temperature, all isolates produced fumonisin B1 only on irradiated maize grain, but not on wheat or barley. This might be a reason for the low natural occurrence of fumonisins on those grains. 相似文献
