| 1 | Integrated application of some compatible biocontrol agents along with mustard oil seed cake and furadan on Meloidogyne incognita infecting tomato plants显示文摘Experiments were carried out to study the effect of two fungal bioagents along with mustard oil cake and furadan against root knot nematode Meloidogyne incognita infecting tomato under greenhouse condition. Bioagents viz., Paecilomyces lilacinus and Trichoderma viride alone or in combination with mustard cake and furadan promoted plant growth, reduced number of galls/plant, egg masses/root system and eggs/egg mass. The fungal bioagents along with mustard cake and nematicide showed least nematodes reproduction factor as compared to untreated infested soil. | GOSWAMI Bijoy Kumar PANDEY Rajesh Kumar RATHOUR Kabindra Singh BHATTACHARYA Chaitali SINGH Lokendra | 2006 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2006，7，11： | 3 |

| 3 | A Novel Approach for Enhancement of Geometric and Contrast Resolution Properties of Low Contrast Images显示文摘The present work encompasses a new image enhancement algorithm using newly constructed Chebyshev fractional order differentiator. We have used Chebyshev polynomials to design Chebyshev fractional order differentiator. We have generated the high pass filter corresponding to it. The designed filters are applied for decomposing the input image into four bands and low-low(L-L) sub-band is updated using correction coefficients. Reconstructed image with updated L-L sub-band provides the enhanced image. The visual results obtained are encouraging for image enhancement. The applicability of the developed algorithm is illustrated on three different test images.The effects of order of differentiation on the edges of images have also been presented and discussed. | Koushlendra Kumar Singh Manish Kumar Bajpai Rajesh Kumar Pandey | 2018 | IEEE/CAA Journal of Automatica Sinica2018，5，2： | 0 |
| 4 | An Improved Methodology to Overcome Key Issues in Human Fecal Metagenomic DNA Extraction显示文摘Microbes are ubiquitously distributed in nature, and recent culture-independent studies have highlighted the significance of gut microbiota in human health and disease. Fecal DNA is the primary source for the majority of human gut microbiome studies. However, further improvement is needed to obtain fecal metagenomic DNA with sufficient amount and good quality but low host genomic DNA contamination. In the current study, we demonstrate a quick, robust, unbiased,and cost-effective method for the isolation of high molecular weight(>23 kb) metagenomic DNA(260/280 ratio >1.8) with a good yield(55.8 ± 3.8 ng/mg of feces). We also confirm that there is very low human genomic DNA contamination(eubacterial: human genomic DNA marker genes = 2^(27.9):1) in the human feces. The newly-developed method robustly performs for fresh as well as stored fecal samples as demonstrated by 16 S r RNA gene sequencing using 454 FLX+.Moreover, 16 S r RNA gene analysis indicated that compared to other DNA extraction methods tested, the fecal metagenomic DNA isolated with current methodology retains species richnessand does not show microbial diversity biases, which is further confirmed by q PCR with a known quantity of spike-in genomes. Overall, our data highlight a protocol with a balance between quality,amount, user-friendliness, and cost effectiveness for its suitability toward usage for cultureindependent analysis of the human gut microbiome, which provides a robust solution to overcome key issues associated with fecal metagenomic DNA isolation in human gut microbiome studies. | Jitendra Kumar Manoj Kumar Shashank Gupta Vasim Ahmed Manu Bhambi Rajesh Pandey Nat Singh Chauhan | 2016 | Genomics, Proteomics & Bioinformatics2016，14，6： | 0 |
