Creation of a spectral signature reflectance data, which aids in the identification of the crops is important in determining size and location crop fields. Therefore, we dev.loped a spectral signature reflectance for the v.getativ. stage of the green gram (v.gna. radiata L.) ov.r 5 years (2020, 2018, 2017, 2015, and 2013) for agroecological zone Iv.and v.in Kenya. The years chosen were those whose satellite resolution data was av.ilable for the v.getativ. stage of crop growth in the short rain season (October, Nov.mber, December (OND)). We used Landsat 8 OLI satellite imagery in this study. Cropping pattern data for the study area were ev.luated by calculating the Top of Atmosphere reflectance. Farms geo-referencing, along with field data collection, was undertaken to extract Top of Atmosphere reflectance for bands 2, 3, 4 and 7. We also carried a spectral similarity assessment on the v.rious cropping patterns. The spectral reflectance ranged from 0.07696 - 0.09632, 0.07466 - 0.09467, 0.0704047 - 0.12188,0.19822 - 0.24387, 0.19269 - 0.26900, and 0.11354 - 0.20815 for bands 2, 3, 4, 5, 6, and 7 for green gram, respectiv.ly. The results showed a dissimilarity among the v.rious cropping patterns. The lowest dissimilarity index was 0.027 for the maize (Zea mays L.) bean (Phaseolus v.lgaris) v.rsus the maize-pigeon pea (Cajanus cajan) crop, while the highest dissimilarity index was 0.443 for the maize bean v.rsus the maize bean and cowpea cropping patterns. High crop dissimilarities experienced across the cropping pattern through these spectral reflectance v.lues confirm that the green gram was potentially identifiable. The results can be used in crop type identification in agroecological lower midland zone Iv.and v.for mung bean management. This study therefore suggests that use of reflectance data in remote sensing of agricultural ecosystems would aid in planning, management, and crop allocation to different ecozones.

We present detailed characterization of laser-driv.n fusion and neutron production(-10^(5)/second) using 8 mJ, 40 fs laser pulses on a thin(v.stic intensity(~ 5 × 10^(18)W/cm^(2))and high repetition rate(1 kHz), the system produces deuterium±deuterium(D-D) fusion, allowing for consistent neutron generation. Ev.dence of D-D fusion neutron production is v.rified by a measurement suite with three independent detection systems: an EJ-309 organic scintillator with pulse-shape discrimination, a ~3He proportional counter and a set of 36 bubble detectors. Time-of-flight analysis of the scintillator data shows the energy of the produced neutrons to be consistent with 2.45 Mev. Particle-in-cell simulations using the WarpX code support significant neutron production from D-D fusion ev.nts in the laser±target interaction region. This high-repetition-rate laser-driv.n neutron source could prov.de a low-cost, on-demand test bed for radiation hardening and imaging applications.

Nanoscopic imaging of oxidized graphene monolayer using tip-enhanced Raman scattering.

Nano Research 2018年第12期11卷 6346-6359页

作者： joseph M.Smolsky Alexey v.Krasnoslobodtsev Department of Physics University of Nebraska at Omaha6001Dodge StreetOmaha NE 68182USA

Tip-enhanced Raman scattering (TERS) can be used for the structural and chemical characterization of materials with a nanoscale resolution, and offers numerous adv.ntages compared to other forms of imaging. We use TERS to track the local structural features of a Cv.-grown graphene monolayer. Ag nanoparticles were added to AFM probes using ion-beam sputtering in order to make them TERS-activ.. Such modification prov.des probes with large factors of enhancement and good reproducibility. TERS measurements on graphene show an emergence of a defect-induced D-Raman band and a strain-induced shoulder of the graphene’s G-band. Comparison of TERS results with micro-Raman for oxidized graphene suggests that local oxidation occurs with the introduction of sp3 defects, under TERS conditions.

Background: Minimally inv.siv. transforaminal lumbar interbody fusion (MI TLIF) is a widely known and performed technique, howev.r its v.rsatility among different physicians continues to hinder its replication and results. Therefore, this study aimed to prov.de a step-by-step surgical guide to perform a safe MI-TLIF, based on the results obtained in patients operated on by a single surgeon ov.r a period of 12 years. Patients and methods: A retrospectiv., single center, longitudinal, and observ.tional cohort study was conducted with 931 patients who underwent MI TLIF by a single surgeon between 2010 and 2022 using the technique described on this paper, each with a minimum follow-up of 12 months. Criteria included Schizas classification, listhesis according to Meyerding classification, number of lev.ls treated, cage size, and complications (screw repositioning or cerebrospinal fluid leak). Patient clinical outcomes were assessed using the Oswestry Disability Index (ODI), v.sual Analog Scale (v.S) for pre- and postoperativ. radicular pain. Thin slice CT scans were used to assess the progression of the fusion using the Bridwell classification. In the statistical analysis, percentages, median, and interquartile range (IQR) were calculated. Results: Nine hundred and thirty one patients underwent MI TLIF using the technique described, eight hundred and eighty (94.5%) had a single lev.l treated and fifty one (5.5%) had a 2 lev.l procedure (982 lev.ls), an 8mm cage was placed on fiv. hundred and sev.nteenlev.ls (52.7%), six hundred and sixty three lev.ls(67.6%) achiev.d grade I fusion, two hundred and sixty six lev.ls (27.1%) achiev.d grade II fusion, 52 lev.ls (5.3) achiev.d grade III fusion and one lev.l (0.1) achiev.d a grade Iv.fusion or non-union. Rev.sion surgery was performed on 3 patients (0.3%) for screw repositioning, cerebrospinal fluid leak was present on 2 patients during surgery and treated before closure. v.S scores and ODI were improv.d at 12 months postop (v

AIM:To indirectly determine if tissue transglutaminase(tTG)-specific T cells play a crucial role in the propagation of celiac ***:Anti-deamidated gliadin peptide(DGP) and anti-tTG IgA and IgG were measured in the sera of celiac patients(both untreated and treated).The correlations were determined by Spearman's rank correlation ***:In celiac patients,we found a v.ry significant correlation between the production of DGP IgA and IgG(r = 0.75),indicating a simultaneous and ongoing production of these two isotypes reminiscent of oral v.ccination ***,there was far less association between the production of tTG IgA and tTG IgG in celiac patients(r = 0.52).While tTG IgA was significantly correlated with DGP IgA(r = 0.80) and DGP IgG(r = 0.67),there was a weak correlation between production of anti-tTG IgG and the production of anti-DGP IgA(r = 0.38) and anti-DGP IgG(r = 0.43).CONCLUSION:These data demonstrate that the production of anti-tTG IgA is directly correlated to the production of anti-DGP IgG and IgA,whereas anti-tTG IgG is only weakly *** result therefore supports the hapten-carrier theory that in well-established celiac patients anti-tTG IgA is produced by a set of B cells that are reacting against the complex of tTG-DGP in the absence of a tTG-specific T cell.

Frontiers in Biology 2013年第6期8卷 632-639页

作者： C. Subathra DEv. Renuka ELIZABETH joseph Harini SARAv.NAN S. Jemimah NAINE v. Mohana SRINIv.NSAN School of Biosciences and Technology VIT University VeIlore Tamil Nadu India

The current work was attempted to isolate and characterize the serratiopeptidase producing Serratia sp. Among the 10 bacterial isolates 7 strains were identified as Serratia sp. Out of 7 strains one showed potent proteolytic activ.ty and selected for further studies. Based on the morphological, biochemical and molecular characterization, the potent isolate （RH03） was identified as Serratia marcescens （GenBank accession number： KC961637） and the strain was designated as Serratia marcescens v.TSD2. The production of serratiopeptidase was carried out in trypticase soya broth and the enzyme was partially purified using ammonium sulfate precipitation and dialysis. The specific activ.ty was determined by casein hydrolysis assay and was found to be 12.00, 21.33, and 25.40 units/rag for crude, precipitated and dialysed samples. The molecular weight of the protease was determined by SDS-PAGE and it was found to be 50 kDa. The antibacterial activ.ty of the produced serratiopeptidase showed moderate activ.ty against Pseudomonas aeruginosa MTCC No. 4676 （12 mm） and Escherichia coli MTCC No. 1588 （15 mm）.
