作者： paul gibson

ISBN: (纸本)9780415189613

Introduction to Remote Sensing: Digital Image Processing and Applications presents a unique textbook/CD-ROM package. It explains how digital images can be processed and offers practical hands-on experience of image processing. This package, which is ideal for student self-study, institutional or library purchase, shows how digital images can be processed to maximize information output and discusses a range of environmental monitoring techniques. A range of case studies are explored, drawn from a variety of disciplines and from across the world. The book also includes a practical manual of image processing instruction and detailed practical exercises to support the unique CD-ROM which accompanies the book. The CD-ROM, included with every book contains fully functioning image processing software - a limited edition of DRAGON software developed specifically for readers of Introductory Remote Sensing - and over 70 satellite digital datasets for 9 scenes across America, Ireland, China, Sudan, Peru, Western Europe and the UK.

Yield Stability and Late Blight Resistance Analysis among Potato Clones Bred with Quantitative Resistance

引用

Journal of Agricultural Science and Technology(B) 2014年第9期4卷 683-690页

Thirteen promising clones from population B3C2 potato genotypes （bred for quantitative resistance to late blight） obtained from the International Potato Center and three control cultivars were evaluated for four planting dates within two cropping seasons at Kalengyere Research Station in Southwestern Uganda in order to determine performance and yield stability. The analysis of variance of the relative area under disease progress curve （rAUDPC） revealed significant difference （P 〈 0.001） among genotype x planting date interaction, and significant difference （P 〈 0.001） among genotypes x fungicide treatments x planting date interaction. The analysis of variance （ANOVA） of yield revealed also significant difference among genotypes x planting date interaction and significant difference （P 〈 0.05） among genotypes x fungicide treatments x planting date interaction, showing the variable response of genotypes and the need for stability analysis. The additive main effects and multiplicative interactive （AMMI） statistical model showed that the most stable and high yielding genotypes were 396038.107, 396026.103 and 393280.82. The cultivars Victoria, Nakpot 5 and Cruza recorded low yields （below the average）, but Nakpot 5 was generally more variable, and is therefore highly adaptable to some environments.

Evaluation of Cowpea Genotypes for Resistance to <i>Fusarium redolens</i>in Uganda

American Journal of Plant Sciences 2017年第9期8卷 2296-2314页

Fusarium redolens, a virulent fungus which causes damping off, leaf yellowing, wilting and root rots has recently been devastating cowpea fields in Uganda. This study aimed at identifying cowpea genotypes that are resistant to Fusarium redolens. Therefore, ninety cowpea genotypes were evaluated two times against a highly virulent Fusarium redolens (isolate from Zombo in Paidha district) in the screen house in 2016. Genotype effect was highly significant (P 0.001) for root rot severity. Based on the Index of Susceptibility (IS), three genotypes (Asontem, Dan1 LA and IT89KD-88) remained resistant (IS 3.5) over the two screening periods, 72 moderately resistant (3.5 ≤ IS 6.5) and 11 susceptible (IS ≥ 6.5). Resistance was found to be enhanced by presence of lateral roots above or at the ground level. Further results suggested a difference in genetic control of resistance to root rots and seed rots caused by Fusarium redolens. All the released varieties tested (SECOW 1 T, SECOW 2 W, SECOW 3 B, SECOW 4 W and SECOW 5 T) had moderate resistance to Fusarium redolens. Correlation analysis revealed root rot severity was strongly correlated to disease incidence (+0.64, P 0.001), to proportion of plants with lateral roots (-0.56, P 0.001), to amount of leaf chlorophyll (-0.53, P 0.001) and to proportion of plants that died prematurely due to Fusarium redolens infection (+0.45, P 0.001). No significant correlation was detected between root rot severity and proportion of plants that germinated. The established resistance could be exploited for improvement of farmer preferred cowpea varieties towards Fusarium redolens resistance in Uganda.

Response of Cowpea Genotypes to Drought Stress in Uganda

引用

American Journal of Plant Sciences 2017年第4期8卷 720-733页

Moisture stress is a challenge to cowpea production in the drought prone areas of eastern and north eastern Uganda, with yield losses of up to 50% reported. Genotypes grown by farmers are not drought tolerant. This study was therefore, undertaken at Makerere University Agricultural Research Institute Kabanyolo to identify cowpea genotypes tolerant to drought. Thirty cowpea accessions comprising of Ugandan landraces and released varieties, Brazilian lines, Makerere University breeding lines, elite IITA germplasm and seven IITA?drought tolerant lines as checks were screened for drought tolerance at vegetative and reproductive stages. The experiment was designed as a 2 × 37 factorial and laid out in a split-plot arrangement, 37 genotypes of cowpea at two soil moisture stress levels (T1, no stress and T2, severe stress) with all factorial combinations replicated two times in a screen house. The genotypes showed considerable variability in tolerance to drought. Genotypes were significantly different for chlorophyll content (P ≤ 0.01), efficiency of photosystem II (P ≤ 0.05), non-photochemical quenching (P ≤ 0.05), recovery (P ≤ 0.01), delayed leaf senescence (P ≤ 0.01), grain yield (P ≤ 0.01), 100 seed weight (P ≤ 0.05), number of pods per plant and number of seeds per pod (P ≤ 0.001). There was a highly significant positive correlation between chlorophyll content and efficiency of photosystem II (r = 0.75, P ≤ 0.001) implying that chlorophyll content and efficiency of photosystem II could be used as efficient reference indicators in the selection of drought tolerant genotypes. Genotypes SECOW 5T, SECOW 3B, SECOW 4W, WC 30 and MU 24 C gave relatively high yields under stress and no stress conditions, maintained above mean chlorophyll content, efficiency of photosystem II and had good recovery scores from stress and thus were tolerant to drought stress induced at both vegetative and reproductive stages.

支气管哮喘（哮喘）是具有异质性的气道炎症性疾病，其主要特点表现为气道高反应和可变的气流受限。在哮喘的发病机制中，过敏原诱导的TH2淋巴细胞激活以及IL-5介导的嗜酸粒细胞渗出起到重要的作用。近年来发现超过50％的哮喘患者气道的嗜酸粒细胞水平并不增高，并将这种亚型定义为非嗜酸粒细胞型哮喘。其中部分患者表现为气道中性粒细胞明显增高，称为中性粒细胞型哮喘。

＜正＞Now that the refurbishment of the Z machine at Sandia is complete we are routinely operating with currents over 26 MA into various *** routine operation we are able to measure current and voltage throughout the machine and compare with circuit code predictions. These measurements have motivated improvements to the original model to include two-dimensional （2D） and three-dimensional （3D） *** this paper we describe a full-machine （36 module）,one-dimensional （1D） circuit model of Z using the Bertha code developed at the Naval Research *** also describe a model that uses 2D *** addition,we discuss plans for implementing a 3D circuit model to allow investigating azimuthal effects that can be important for tailoring the rise time,shape,and length of the Z output *** tailoring on Z is achieved by staggering the timing of the various pulsed-forming modules,and by operating individual modules in either long or short-pulse *** the individual lines combine at a large diameter and are separated azimuthally, transit-time effects can be important for determining transient field enhancements at the vacuum insulator and in the vacuum transmission lines,as well as pulse "shape. Finally,we compare the 1D and 2D models with data, and provide predictions for both short and long pulse modes for various load configurations.
