On Planetary Electromagnetism and Gravity

引用

International Journal of Astronomy and Astrophysics 2011年第2期1卷 62-66页

作者： ashwini kumar Lal 不详

Study of the interiors of the various terrestrial planets, as presented in the paper, leads to the possibility of planetary gravity being linked to the electromagnetism generated in the planetary interiors. Findings of the study undertaken suggest that Earth’s gravitational attraction may be attributed to magnetic coupling experi-enced between Earth's electromagnetism and all the earthly objects - electrically charged or uncharged. More precisely, terrestrial gravity is deemed to be outcome of the bound state of the planetary electromagnetism.

Probiotic Screening of Lactobacilli Isolates from Uttapam Batter Fermented Supplementing with Piper betleL. Leaves

引用

Advances in Microbiology 2015年第13期5卷 858-870页

作者： ashwini kumar Dubey Kadirvelu Jeevaratnam Department of Biochemistry and Molecular Biology Pondicherry University Puducherry India

The in vitro screening of lactobacilli isolates from uttapam batter, fermented supplementing with Piper betle L. leaves, was performed in order to select potent isolates for probiotic use. Their resistance to simulated gastric and intestinal juices as well as their adhesion to epithelial intestinal HCT-15 and vaginal HeLa cell lines were assessed and also evaluated for their immunomodulatory ability in ex vivo condition. Isolates were able to adhere as well as reduce pathogen adhesion to monolayer cell lines’ surfaces and reduced production of pro-inflammatory cytokine TNF-α in LPS treated PBMCs, while enhanced that of anti-inflammatory cytokine IL-10. The isolates exhibited properties of auto-aggregation, co-aggregation, hydrophobicity, bile salt hydrolase activity and strong antimicrobial activity against pathogenic bacteria. Thus, the different lactobacilli isolates displayed potent probiotic and immunomodulatory properties among which AJ7 and AJ82 had a great potential and may have applications in fermented foods as immunomodulatory probiotic additives.

Secular evolution of continental crust: recorded from massif-type charnockites of Eastern Ghats belt, India

引用

Natural Science 2010年第10期2卷 1079-1084页

作者： Samarendra Bhattacharya ashwini kumar Chaudhary 不详

It is reasonably well established that the Earth has substantially cooled from the Archean to the pre-sent and hence the sites, rates and pro- cesses of crust formation must have changed through geo-logic time. Archean and Proterozoic granitic rocks are the principal record of such changes. Massif-type charnockites in the Eastern Ghats granulite belt, India, of Archean and Proterozoic ages mirror the changing conditions and/or processes of continental crust for- mation. Though both can be explained by dehydration melting of mafic rocks, the conditions differ. Potasium and rubidium rich Proterozoic charnockites have significant negative Eu ano- maly indicating melting at shallow depths in the stability field of plagioclase. In contrast, sodium and strontium rich Archean charnockites with less LREE enrichment and less depletion in Eu indicate melting at greater depths in the stability field of garnet or amphibole.

Journal of Modern Physics 2012年第10期3卷 1479-1486页

作者： Kamal Lochan Mahanta ashwini kumar Biswal Department of Mathematics C. V. Raman College of Engineering Bhubaneswar India

We have constructed cosmological models for string cloud and domain walls coupled with quark matter in Lyra geometry. For this purpose we have solved the field equations using anisotropy feature of the universe, special law of variation for Hubble’s parameter proposed by Berman [78] which yields constant deceleration parameter;and time varying displacement field . Further some properties of the obtained solutions are discussed.

Occurrence of N-Acyl Homoserine Lactones in Extracts of Bacterial Strain of Pseudomonas aeruginosaand in Sputum Sample Evaluated by Gas Chromatography–Mass Spectrometry

引用

American Journal of Analytical Chemistry 2011年第2期2卷 294-302页

作者： Susheela Rani ashwini kumar Ashok kumar Malik P. Schmitt-Kopplin 不详

This study presents a fast, accurate and sensitive technique using gas chromatography-mass spectrometry (GC-MS) for the identification and quantification of N-acyl homoserine lactones (AHLs) in the extracts of bacterial strain of Pseudomonas aeruginosa and sputum sample of a cystic fibrosis patient. This method involves direct separation and determination of AHLs by using GC-MS as simultaneous separation and characterization of AHLs were possible without any prior derivatiza-tion. Electron ionization resulted in a common fragmentation pattern with the most common fragment ion at m/z 143 and other minor peaks at 73, 57 and 43. The limit of detection for N-butanoyl, N-hexanoyl, N-octanoyl, N-decanoyl, N-dodecanoyl and N-tetradecanoyl homoserine lactones was 2.14, 3.59, 2.71, 2.10, 2.45 and 2.34 μg/L, respectively. The presence of AHLs in the culture of P. aeruginosa strain and spu-tum of a cystic fibrosis patient was achieved in selected ion monitoring (SIM) mode by using the prominent fragment at m/z 143.

作者： ashwini kumar Arya Amalendu Patnaik Machavaram V. Kartikeyan 不详

Use of defected ground structure (DGS) to reduce the size of patch antenna is presented in this paper. In order to get a dipole like radiation pattern for some specific application a dumbbell shaped DGS is used in the common ground plane of back to back combined single fed proximity coupled antenna. A size reduction of about 60% is achieved. Parametric analysis has been done to see the resonance behavior of the antenna with DGS.
