Efficient Ranked Keyword Using AML

Entity Recognition is process of identifying predefined entities such as person names, products, or locations in a given docu ment. This is done by finding all possible substrings from a document that match any reference in the given entity dictionary. Approximate Membership Extraction (AME) method was used for finding all substrings in a given document that can approximately match any c lean references but it generates many redundant matched substrings because of approximation (rough calculation), thus rendering AME is not suitable for real - world tasks based on entity extraction. We propose a web - based join framework which combines a web search along with the approximate membership localization. Our process first provides a top n number of documents fetched from the web using a general search using the given query and then approximate membership localization(AML) is applied on these documents using the clear reference table and extra cts the entities form the document to form the intermediate reference table using Edit distance Vector, Score Correlation

Microwave assisted extraction of mangiferin from Curcuma amada

Mangiferin present in Curcuma amada was extracted with the help of microwave assisted extraction (MAE). The extraction solvent used was ethanol, which is eco-friendly and reduced the risk of environmental hazard. The mangiferin content was found to increase until 500 W, but decreased as the microwave power was increased further. A similar threshold was also obtained for microwave irradiation time. Following a mathematical analysis, an optimal mangiferin yield of 41 μg/mL was obtained from an extraction time of 15.32 s for a microwave power of 500 W

Effects of Dielectrophoresis on Growth, Viability and Immuno-reactivity of Listeria monocytogenes

Dielectrophoresis (DEP) has been regarded as a useful tool for manipulating biological cells prior to the detection of cells. Since DEP uses high AC electrical fields, it is important to examine whether these electrical fields in any way damage cells or affect their characteristics in subsequent analytical procedures. In this study, we investigated the effects of DEP manipulation on the characteristics of Listeria monocytogenes cells, including the immuno-reactivity to several Listeria-specific antibodies, the cell growth profile in liquid medium, and the cell viability on selective agar plates. It was found that a 1-h DEP treatment increased the cell immuno-reactivity to the commercial Listeria species-specific polyclonal antibodies (from KPL) by ~31.8% and to the C11E9 monoclonal antibodies by ~82.9%, whereas no significant changes were observed with either anti-InlB or anti-ActA antibodies. A 1-h DEP treatment did not cause any change in the growth profile of Listeria in the low conductive growth medium (LCGM); however, prolonged treatments (4 h or greater) caused significant delays in cell growth. The results of plating methods showed that a 4-h DEP treatment (5 MHz, 20 Vpp) reduced the viable cell numbers by 56.8–89.7 %. These results indicated that DEP manipulation may or may not affect the final detection signal in immuno-based detection depending on the type of antigen-antibody reaction involved. However, prolonged DEP treatment for manipulating bacterial cells could produce negative effects on the cell detection by growth-based methods. Careful selection of DEP operation conditions could avoid or minimize negative effects on subsequent cell detection performance

Induced chlorophyll mutations in Gloriosa superba

The present experiment was carried out to study the spectrum of chlorophyll mutations, mutagenic effectiveness and efficiency in Gloriosa superba seeds using both chemical and physical mutagens. Self pollinated seeds of glory lily ecotype Gs-15 were treated with different doses of gamma rays viz., 10, 20, 30 and 40 (Gy), EMS viz., 10, 20, 30 and 40 mM and DES 15, 20, 25 and 30 mM. Both physical and chemical mutagens had significantly contributed to the production of the spectrum of chlorophyll mutants with higher mutagenic effectiveness and efficiency. The treatment of mutagens resulted in the production of four types of chlorophyll mutants viz., albina, xantha, chlorina and viridis. The mutagenic effectiveness and efficiency were calculated based on biological damage as well as chlorophyll mutation frequency on M1 plants. The results indicated that the mutagenic efficiency was the highest, at lower and intermediate concentrations of mutagens. The frequency of xantha (8.36) mutants were the highest followed by viridis (7.01) and other types were observed in all the treatments. Among different treatments, gamma rays were effective than the other two chemical mutagens in inducing different chlorophyll mutations. A comparatively lesser number of albina (2.13) mutants were observed with respect to all the mutagens studied. The higher frequency of mutations was observed in gamma irradiated seedlings (28.28) as compared to EMS (17.57) and DES (11.96). Likewise, the mutagenic effectiveness was at an increased score (81.10%) with 10 Gy gamma irradiation treatment. With regard to the EMS, based on lethality, increased mutagenic efficiency (27.37%) was observed at 20 mM concentration. Conversely, lower doses of physical mutagen (gamma radiation) induced a higher mutagenic rate, while EMS registered a lower score of mutations

Water Deficit Transcriptomic Responses Differ in the Invasive Tamarix chinensis and T. ramosissima Established in the Southern and Northern United States

Tamarix spp. (saltcedar) were introduced from Asia to the southern United States as windbreak and ornamental plants and have spread into natural areas. This study determined differential gene expression responses to water deficit (WD) in seedlings of T. chinensis and T. ramosissima from established invasive stands in New Mexico and Montana, respectively. A reference de novo transcriptome was developed using RNA sequences from WD and well-watered samples. Blast2GO analysis of the resulting 271,872 transcripts yielded 89,389 homologs. The reference Tamarix (Tamaricaceae, Carophyllales order) transcriptome showed homology with 14,247 predicted genes of the Beta vulgaris subsp. vulgaris (Amaranthaceae, Carophyllales order) genome assembly. T. ramosissima took longer to show water stress symptoms than T. chinensis. There were 2068 and 669 differentially expressed genes (DEG) in T. chinensis and T. ramosissima, respectively; 332 were DEG in common between the two species. Network analysis showed large biological process networks of similar gene content for each of the species under water deficit. Two distinct molecular function gene ontology networks (binding and transcription factor-related) encompassing multiple up-regulated transcription factors (MYB, NAC, and WRKY) and a cellular components network containing many down-regulated photosynthesis-related genes were identified in T. chinensis, in contrast to one small molecular function network in T. ramosissima
