In order to explore the optimal decolorization technology of paulownia wood suitable for middle and small Enterprises to obtain its high added values, the chemical processing method was used to solve the difficult problem of paulownia wood decolorization. The results showed that: 1) temperature, pressure, time and treatment solution concentration all had significant effects on the decolorizatio...

The Zero Valent Iron (ZVI) is the material most commonly used for permeable reactive barriers (PRB). For technical and economic reasons, hoter reactive substances usable in alternative to ZVI are investigated. The present study takes into account a vegetable fibers, the cabuya, investigating its capacity to retain heavy metals. The capacity of the cabuya fibers to adsorb heavy metals was verifi...

A new camera model for transforming object space coordinates into image coordinates as affected by a push-broom sensor traveling in a straight line is described. It is shown that this transformation can be encoded in a 3 × 4 matrix M representing a non-linear Cremona transformation of object space into image space. Significantly, unlike other known models for satellite cameras, M can be estimat...

This paper proposes a systematic image mosaicking methodology to produce hyperspectral for environment monitoring using an emerging UAV-based push-broom imager. The suitability of alternative methods in each step is assessed by experiments urban scape, river course and forest study area. First, the strips were acquired sequentially stitching UAV images scanning along flight line. Next, direct g...

BACKGROUND: We have previously shown that use of an EC brush device in combination with the Rovers Cervex-Brush (SurePath broom) offered no significant improvement in EC recovery. Here we determine if use of additional collection devices enhance the diagnostic utility of the SurePath Pap for gynecologic cytology. METHODS: After informed consent, 37 women ages 18-56 receiving their routine cervi...

An empirical model is proposed to solve the problem that exists in in-orbit calibration method for TDICCD camera in this paper. The method brings in the line frequency normalization and virtual image stitching from TDICCD images to the preprocessing procedure, which makes the virtual mosaic images has the same characteristics as the regular Linear push-broom CCD images, therefore the interior a...

Hyperspectral remote sensing images are affected by different types of noise. In addition to typical random noise, nonperiodic partially deterministic disturbance patterns generally appear in the data. These patterns, which are intrinsic to the image formation process, are characterized by a high degree of spatial and spectral coherence. We present a new technique that faces the problem of remo...

DNA was isolated from clover proliferation (CP) mycoplasmalike organism (MLO)-diseased periwinkle plants (Catharanthus roseus (L.) G. Don.) and cloned into pSP6 plasmid vectors. CP MLO-specific recombinant DNA clones were biotin labeled and used as probes in dot hybridization and restriction fragment length polymorphism analyses to study the genetic interrelatedness among CP MLO and other MLOs,...

MicroRNAs (miRNAs) play an important role in responding to biotic and abiotic stresses in plants. Jujube witches'-broom a phytoplasma disease of Ziziphus jujuba is prevalent in China and is a serious problem to the industry. However, the molecular mechanism of the disease is poorly understood. In this study, genome-wide identification and analysis of microRNAs in response to witches'-broom was ...

This paper, based on hitherto unpublished correspondence between Robert Broom and Paul Adloff, supports the claim that Broom did not, in fact, classify Australopithecus as a member of the hominid family, as propounded by some authors.
