Accurate extraction of pores and fractures is a prerequisite for constructing digital rocks physical property simulation microstructural response analysis. However, in CT images are similar grayscale to the rock matrix, traditional algorithms have difficulty achieve accurate segmentation results. In this study, dataset containing multiscale fracture information was constructed, U-Net semantic model with scSE attention mechanism used classify shale at pixel level compare results methods. The...
In this work, Au-modified F-TiO2 is developed as a simple and efficient photocatalyst for H2O2 production under ultraviolet light. The Au/F-TiO2 avoids the necessity of adding fluoride into reaction medium enhancing synthesis, in pure TiO2 system. F− modification inhibits decomposition through formation ≡Ti–F complex. Au an active cocatalyst photocatalytic production. We compared activity with without presence Au, found that rate over reaches four times Au/TiO2. situ electron spin resonance...
Sugarcane smut is the most severe sugarcane disease in China. The typical symptom emerging of a long, black whip from top plant cane. However, 2018, for first time we observed floral structures infected by fungus planting fields Such smut-associated inflorescence was generally curved and short, with small whips glumes single floret on cane stalk. Compatible haploid strains, named Ssf1-7 (MAT-1) Ssf1-8 (MAT-2), isolated teliospores that formed were selected sexual mating assay, ITS DNA...
Sugarcane smut, a serious disease caused by the fungus Sporosorium scitamineum, can result in 30% to 100% cane loss. The most affordable and efficient measure of preventing handling sugarcane smut is select disease-resistant varieties. A comprehensive evaluation resistance based on incidence essential during selection process, necessitating rapid accurate identification smut. Traditional methods, which rely visual observation symptoms, are time-consuming, costly, inefficient. To address...
A ceftiofur hydrochloride long-acting oily suspension with no irritation was prepared by testing and optimizing the types amounts of organic solvents, suspending agents, surfactants.Its properties, stability, injection site irritation, in vitro release, pharmacokinetics pigs were evaluated. The optimum formulation used ethyl oleate, aluminum monosterate, span-80 as surfactant, respectively. drug microparticles uniform long strip size 1.53 ± 0.11 μm agglomerations, evenly dispersed....
A magnetically focused x-ray streak camera was designed and tested using sub-200 fs soft pulses generated by high harmonic emission in a gas. The temporal resolution of the demonstrated to be under 0.54 ps for ultraviolet 0.88 soft-x-ray wavelength region. Our represents fastest detector developed date, should allow sub-picosecond time experiments performed either synchrotron or laser-plasma-based sources.
We describe our research on the employment of an infrared upconversion screen made electron trapping material (ETM) in combination with high sensitivity S-20 photocathode responsive to visible radiation produce a streak camera arrangement capable viewing and recording incident pulses. The ETM-based converts 800–1600 nm light which is viewed or recorded by photocathode. peak values efficiency are located at 1165 for CaS:Eu, Sm 1060 CaS:Ce, Sm. present experiment showed time resolution was...
Objective To explore the effects of knowledge-attitude-practice (KAP) education model on standardization in using dry powder inhaler (DPI) and quality life among patients with COPD. Methods A total 120 COPD DPI during follow-up period Department Respiratory for Adults at Second Affiliated Hospital Wenzhou Medical University were selected as study subjects by convenience sampling from March 2014 to 2016. They randomly divided into observation group (n=60, conventional education)...
Ultra high-speed streak cameras with image converter tubes play a very important role in the diagnosis of most experiments laser fusion research. The window materials tube usually applied borosilicale glass, but it is only transparent for visible light. In order to apply VUV.UV.visible light region tube, we used MgF<SUB>2</SUB> material and exhibits excellent performance on photocathode sensitivity spectral responses tube.
The paper describes our research on infrared-sensitive streak camera that adopts a tube with complex photocathode which consists of membrane made up-converting material (one kind ET material) and S-20 photocathode. up- converting screen is able to convert 800 nm - 1600 infrared radiation visible light. peak values the efficiency are located at 1165 for CaS:Eu, Sm 1060 CaS:Ce, Sm. We obtained novel result time resolution ET-materials attains 12.3 ps 8.4 screen.
This paper discusses the characterization of a cylindrical microwave resonant cavity used as deflection system convert tube. In two TM<SUB>110</SUB> mode fields vertical to each other are excited and electron beam is deflected by their magnetic field. Unlike usual tube in which electric field, this has some special characters. Calculation shows introduces less spatial temporal aberration, with almost no effect on image quality, scanning speed can be very high. Also confining field cavity,...
A development status evaluation is presented for a picosec soft X-ray streak camera whose initial two-window readout system has been replaced by 512 x 4 computer image processor. In addition, turbomolecular vacuum pump used in place of an ion pump. This both high power laser and optical physics research.
X-ray picosecond framing photography using optical and deflection shuttering has been proposed demonstrated in our laboratory for several years. Four frame dynamic images have obtained with l7Opsec exposure time. The recent modification developments of the image tube camera are described. aim is to decrease time improve spatial resolution.
