Unmanned Aerial vehicles (UAvs) have become increasingly popular in recent years for agricultural research. High spatial and temporal resolution images obtained with UAvs are ideal for many applications in agriculture. The objective of this study was to evaluate the performance of vegetation indices (vIs) derived from UAv images for quantification of plant nitrogen (N) concentration of spring wheat, a major cereal crop worldwide. This study was conducted at three locations in Idaho, United States. A quadcopter UAv equipped with a red edge multispectral sensor was used to collect images during the 2016 growing season. Flight missions were successfully carried out at Feekes 5 and Feekes 10 growth stages of spring wheat. Plant samples were collected on the same days as UAv image data acquisition and were transferred to lab for N concentration analysis. Different vIs including Normalized Difference vegetative Index (NDvI), Red Edge Normalized Difference vegetation Index (NDvIred edge), Enhanced vegetation Index 2 (EvI2), Red Edge Simple Ratio (SRred edge), Green Chlorophyll Index (CIgreen), Red Edge Chlorophyll Index (CIred edge), Medium Resolution Imaging Spectrometer (MERIS) Terrestrial Chlorophyll Index (MTCI) and Red Edge Triangular vegetation Index (core only) (RTvIcore) were calculated for each flight event. At Feekes 5 growth stage, red edge and green based vIs showed higher correlation with plant N concentration compare to the red based vIs. At Feekes 10 growth stage, all calculated vIs showed high correlation with plant N concentration. Empirical relationships between vIs and plant N concentration were cross validated using test data sets for each growth stage. At Feekes 5, the plant N concentration estimated based on NDvIred edge showed one to one correlation with measured N concentration. At Feekes 10, the estimated and measured N concentration were highly correlated for all empirical models, but the model based on CIgreen was the only model that had a one to

探讨反向线性杂交技术(reverse line blot assay,RLB)在结核分枝杆菌利福平(RFP)耐药性快速检测中的应用价值。采用RLB将包含rpoB基因核心区的扩增产物与标记特异性探针的膜进行杂交,共对121株结核分枝杆菌进行RFP耐药性检测,并将结果与常规药敏实验进行比较。结果发现,121株中有71株对RFP耐药,56株为多重耐药株;采用RLB共检测到65株RFP耐药株rpoB基因核心区存在突变,其灵敏度为91.5%(65/71);50株RFP敏感株中均未检测到突变,则特异性为100%(51/51);56株多耐药菌株中,92.9%(52/56)存在rpoB基因核心区突变。因此,用RLB检测结核分枝杆菌RFP耐药株具有快速,高效,特异性和灵敏度高的优点,且可用于多耐药菌株的筛选,具有推广和潜在的临床应用价值。

ERYTHROCYTE MEMBRANE GLYCOPHORINS OF CENTRAL AFRICANS AND SOME HEMATOLOGICAL PATIENTS

中华医学杂志(英文版) 1987年第10期100卷 794-794页

作者： Lu Yi-qin Liu Jun-fan Ronald L. Nagel olga O. Blumenfeld Department of Biochemistry Hunan Medical College Changsha Department of Medicine Division of Hematology and Department of Biochemistry Albert Einstein College of Medicine Bronx New York 10461 U.S.A.

We have examined the extent of glycophorin (GP) polymorphism in normal and abnormal human red cell membranes using immunoblotting technics and the following probes: Polyclonal anti-α GP that detects α and δ GP; antiserum to the C-terminal fragment of α GP (residues 82-131) that detects δ GP and all others that differ from α GP in the C-terminal region; and M and N specific monoclonal antibodies detecting the N-terminal octapeptide that specify M and N serological phenotypes. Red cells from 41 Central African normals displayed an invariant profile among all but 5. The invariant profile consisted of monomer and dimer of (M,N) GP and of δ (S,s) GP, γ GP and two other minor components, one of which had not been described before. The five abnormal profiles included two Central Africans with lack of δ GP, most likely S-s-U- serological phenotype which has a 4.9% incidence among them. In three other black individuals differences in the γ GP observed were not previously reported. α GP of all individuals reacted with M and N specific antibodies in accordance with their serologically determined M and N phenotypes, and in all individuals δ GP reacted with the N-specific monoclonal antibody. Only one case of sickle cell disease out of 54 Caucasian and black hematological patients showed a variant GP band (band 3a), the others had all normal pro files, including red cells from whole blood or density-defined fractions in Hb SS patients. Our impression is that GP polymorphism is infrequent among Caucasians but comparatively frequent among Central Africans. Moreover, immunoblotting technics confirmed the presence of Stα glycophorins in the erythrocytes of 5 members from a Japanese family.

Linked to major volcanic eruptions around 536 and 540 CE, the onset of the Late Antique Little Ice Age has been described as the coldest period of the past two millennia. The exact timing and spatial extent of this exceptional cold phase are, however, still under debate because of the limited resolution and geographical distribution of the available proxy archives. Here, we use 106 wood anatomical thin sections from 23forest sites and 20 tree species in both hemispheres to search for cell-level fingerprints of ephemeral summer cooling between 530 and 550 CE. After cross-dating and double-staining, we identified 89Blue Rings(lack of cell wall lignification), nine Frost Rings(cell deformation and collapse), and 93Light Rings(reduced cell wall thickening) in the Northern Hemisphere. Our network reveals evidence for the strongest temperature depression between mid-July and early-August 536 CE across North America and Eurasia, whereas more localised cold spells occurred in the summers of 532, 540–43, and548 CE. The lack of anatomical signatures in the austral trees suggests limited incursion of stratospheric volcanic aerosol into the Southern Hemisphere extra-tropics, that any forcing was mitigated by atmosphere-ocean dynamical responses and/or concentrated outside the growing season, or a combination of factors. Our findings demonstrate the advantage of wood anatomical investigations over traditional dendrochronological measurements, provide a benchmark for Earth system models, support cross-disciplinary studies into the entanglements of climate and history, and question the relevance of global climate averages.

职业教育国家专业教学标准建设对规范学校教学、深化课程改革、提升教育质量等具有重要意义。然而,当前国家专业教学标准建设在诸多方面仍存在不足,亟需借鉴他国经验,进一步反思"如何开发""如何实施"等问题。俄罗斯职业教育国家教育标准以能力为本,开发机构职责分明,开发流程严谨清晰,形成了各级教育标准统一贯通、自上而下的实施路径。我国应促使专业教学标准对接职业标准,实现标准职业性与教育性的融合;调整国家专业教学标准的组织机构,完善开发机制;强调学习成果最低要求,形成国家统一性与地方灵活性相结合的职业教育标准体系。

＜正＞格林兰岛冰盖在上一次间冰期期间（约11万5千年前）比现在的规模小很多,在未来气候变暖的情景下有可能会产生类似的冰盖融化和缩小。冰盖融化产生的淡水如果注入北大西洋,会抑制深对流和深水的形成,从而减弱大西洋经圈环流（AMOC）。由于大量的向极热量输送是由AMOC完成的,它的减弱对北半球的气候将有很大的影响。冰盖融水常常通过一些宽度很窄的冰流或出水口注入海洋中,而从不同位置注入海洋的淡水可能会作用于不同的深水形成区,或者对同一个深水形成区产生不同程度的抑制作用,最终导致不同位置的冰
