Objective: The objective of the present study was to determine the total content of phenolics and flavonoids in selected medicinal plants such as Atuna indica, Baliospermum montanum, Chukrasia tabularis, Humboldtia brunonis var. rakthapushpa and Soymida febrifuga. Methods: The total phenolic content (TPC) was estimated spectrophotometrically using Folin Ciocalteu method. Total flavonoid content (TFC) was measured by aluminium chloride colorimetric assay. Results: The results showed that Chukrasia tabularis (belonging to the family Meliaceae) is the richest source of phenolics and flavonoid (total Phenolic content: 17.2 mg GAE/g and total flavonoid content: 3.82 QE/g). The lowest phenolic content was noticed in Baliospermum montanum (2.72 mg GAE/g) and lowest flavonoid content was observed in Humboldtia brunoniss var. raktapushpa (0.98 mg QE/g). Conclusion: A significant linear correlation was observed between the values for the total phenolic content and antioxidant activity. The high contents of phenolic compounds indicated that these compounds contribute to the antioxidant activity. The Chukrasia tabularis can be regarded as promising plant species for natural plant sources of antioxidants with high potential value for drug preparation.

Big Data are large data sets that are either structured/unstructured collection of various data formats. These repositories are mined for information extraction and decision-making. The data being sensitive draws unauthorized access, prompting to secure each and every vulnerable access points. Security in Big Data is one of the interesting areas that are being researched. This Paper covers an overall framework for the big data security including Data Classification, Authentication, Authorization, Crypto Methods, Logging and Monitoring. Major security concerns appear on the Application level, Network level, Classification level and Analytics level. The breach of security results in sensitive data loss, threats on data misuse and even loss of money for customers. The aim of this paper is to provide a detailed survey on the researches undertaken on the ‘Big Data Security Framework’ area for the past few years through various publications. It also analyses the open problems still existing despite consistent exploration and probable future directions to probe other security options. © Springer International Publishing AG 2017.

The lungs play a very vital role in human respiratory system. It has five separate lobes which are detached by fissures of three types such as left and right oblique fissure and a horizontal fissure. The way of identifying the fissure lobes in computed tomography scanned lung images are difficult for the medical practitioners because of the incorrect shapes alongside with less contrast and the extraordinary noise associated with it [1]. The last phase of the lung cancer treatment is the elimination of the unhealthy lung by the major surgery. So, it is required to identify the location of the cancer affected part of the lungs by extracting the fissure lobes before making the proposal for the surgery. This paper presents a mechanized process of extracting the left oblique fissures and right oblique fissures by applying the Dual Tree Complex Wavelet Transform from the Computed Tomography lung images. This will help the medical practitioner to identify the lobar fissures from the computed tomography lung images. © Springer International Publishing AG 2017.

This paper deals with the problem of delay-dependent global robust asymptotic stability of uncertain switched Hopfield neural networks (USHNNs) with discrete interval and distributed time-varying delays and time delay in the leakage term. Some Lyapunov--Krasovskii functionals are constructed and the linear matrix inequality (LMI) approach are employed to derive some delay-dependent global robust stability criteria which guarantee the global robust asymptotic stability of the equilibrium point for all admissible parametric uncertainties. The proposed results that do not require the boundedness, differentiability, and monotonicity of the activation functions. Moreover, the stability behavior of USHNNs is very sensitive to the time delay in the leakage term. It can be easily checked via the LMI control toolbox in Matlab. In the absence of leakage delay, the results obtained are also new results. Finally, nine numerical examples are given to show the effectiveness of the proposed results. © 2011 Springer-Verlag London Limited.

In this work, the vibrational spectral analysis was carried out by using Raman and infrared spectroscopy in the range 100-4000 cm-1 and 50-4000 cm-1, respectively, for the title molecules. The molecular structure, fundamental vibrational frequencies and intensity of the vibrational bands are interpreted with the aid of structure optimizations and normal coordinate force field calculations based on Hartee Fock (HF) and density functional theory (DFT) method and different basis sets combination. The complete vibrational assignments of wavenumbers were made on the basis of potential energy distribution (PED). The scaled B3LYP/6-311++G(d,p) results show the best agreement with the experimental values over the other methods. The calculated HOMO and LUMO energies show that charge transfer occurs within molecule. The influences of bromine atom and methyl group on the geometry of benzene and its normal modes of vibrations have also been discussed. The results of the calculations were applied to simulated spectra of the title compounds, which show excellent agreement with observed spectra. © 2012 Elsevier B.V. All rights reserved.

Mangrove plants are found to have medicinal values and have been used traditionally by local medical practitioners in worldwide. In nature, more than 65 species of mangrove plants, 18 species are found to be widely used by local medical practitioners in many countries like India, Africa, Southeast Asia, South America, Australia etc. Moreover, etanobotanical records regarding medical use of mangrove plants are very limited and very unique. One to its astringent property, tannin is suitable in the treatment of tonsillitis, pharyngeatis, hemorrhoids. slaik eruion and burns. It is taken internally, to diarrohea and intestinal bleeding. The extracts of barks of Bruguiera sexangula are active against two human tumors, sarcoma 180 and lexis lung carcinoma. Tannin is also used as an antidote for metallic, alkaloidal and sylycosidic poisons with which it forms a soluble precipitate. Stigma sterol has been shown to have slight hyper cholesterolinic effect which exerts no effect on heart or liver in unani medicine. © 2012 Asian Pacific Tropical Medicine Press.

Imaging spectroscopy is an emerging and versatile technique that finds applications in diverse fields concerned with remote identification, discrimination and mapping of materials. The large amount of spectral data produced by hyperspectral imaging necessitates the development of automated techniques that convert imagery directly into thematic maps. Spectral library search method, a method of choice for organic compound identification by the mass spectroscopy, has caught the attention of researchers as one of the appropriate methods for an efficient exploitation of high quality spectral data available from the hyperspectral imaging systems. Given the apparent increase in the number of papers appearing on the subject as well as the variety of methods proposed, it is reasonable to say that the field of automated interpretation of reflectance spectral data has passed its infancy now gaining important space in the scientific community. We present an overall view of the literature relevant to the development of library search method, the various search algorithms and systems available in the purview for developing an automated hyperspectral data analysis system for material identification. © 2013 Copyright Taylor and Francis Group, LLC.

Nutritional requirements at optimal level can contribute considerably to the production cost and the bioprocess economics. Media optimization using response surface methodology is one of the used methods to ameliorate the bioprocess economics. In the present study, Amylase production by Marine actinomycetes Streptomyces gancidicus_ASD was effectively enhanced by response surface methodology. An OFAT (one factor at a time) based statistical screening procedure was adopted to determine the most important factor affecting amylase production. The variables are screened and results show that sucrose and Beef extract concentrations influence the most as carbon and nitrogen source on amylase production respectively. A Central Composite Design was conducted to optimize the four selected factors. Statistical analyses of the data of model fitting were done by using Design expert 10.0(stat-Ease). Results show a maximum predicted Amylase yield of 11460.34 IU/ml when using 1.05 % sucrose, 0.608 % Beef extract, 7.1 pH and 40.35 °C Temperature. The predicted value is approximately 1.24 fold much higher than the original production (9248 IU/mL) determined by the conventional onefactor- at-a-time optimization method which can be applied in bioprocess for increased amylase yield.
