GIS Technique in Management of Watershed Developed along the Konkan Coast, Maharashtra, India  [PDF]
Bhavana Umrikar
Journal of Geographic Information System (JGIS) , 2015, DOI: 10.4236/jgis.2015.73022
Abstract: Coastal watersheds differ from inland by their unique features including proximity to the ocean, weather and rainfall patterns, drainage system, subsurface aquifer conditions and geomorphological units. Land use changes and competing needs for water resources are especially more distinctive to such watersheds. This difference leads to put forward the Integrated Coastal Zone Management (ICZM), and is deemed to provide an operational tool for future researchers, developers and policy makers. Some important attributes necessary for watershed management in terms of land capability zonation include drainage, altitude, geology and slopes. The paper incorporates results of representative watershed namely Shringar Tali watershed. GIS technique was used to generate layers like drainage and springs, geology, contour, slopes and Digital Elevation Model (DEM), essential for watershed management. On the basis of interpretation of layers and superimposed picture obtained, Land Capability Zonation Map (LCZM) was prepared. The scope for spring sanctuary development, agro-forestry and aquaculture development is discussed in the paper.

Abstract: Aim: To investigate the incidence and virulence properties of E. coli in fresh fish and ready-to-eat fish products from retail markets of the Ludhiana the present study was conducted. Materials and Methods: Total of 184 samples comprising 96 raw fish and 88 ready- to-eat (RTE) fish products were collected from Ludhiana and other parts of Punjab and were subjected to suitable microbiological methods for E. coli isolation. E. coli isolates were subjected for haemolytic activity and indicators of plausible cytotoxicity (lecithinase, protease and gelatinase production), congo red dye biding assay. To assess virulence potential isolates were molecularly screened for stx 1 and 2 genes. Results: From raw fish samples 47(48.95%), E. coli, were isolated. From RTE fish products 7(12.96%), E. coli were isolated. Overall incidence for E. coli was 54 (29.34%). In vitro virulence characterization of isolates exhibited that all E. coli isolates were haemolytic while indicators of plausible cytotoxicity ( lecithinase, protease and gelatinase production) were in the range of 16.67% to 35.19% indicated that though the isolates were haemolytic they were perhaps less likely to be cytotoxic. Congo Red binding assay for E. coli isolates revealed that majority (88.89%) of the isolates failed to uptake the dye and only few (11.11%) could bind the dye. Results of serotyping revealed a total of 15 different serotypes among the E. coli isolates. More variation was observed among isolates from raw fish samples (12 serotypes) while RTE fish products harboured only 5 different serotypes. Molecular characterization of E. coli isolates revealed that PCR screening of isolates revealed that total 39 (72.22%) samples out of 54 E. coli isolates were positive for stx1 gene and 28 (51.85%) of isolates were positive for stx2 gene. Sources wise, 36 (66.66%) of isolates from raw fish and 3(5.55%) of isolates from RTE fish products were positive for stx1 while and stx2 gene could be detected in 24(44.44%) isolates from raw fish and 4(7.4%) isolates from RTE fish products.Interestingly, about 20% (37.03%) isolates were positive for both stx1 and stx2 genes. Among these multivirulent isolates majority (n=18) belonged to raw fish samples compared to a few (n=2) from RTE fish products. Conclusion: The results of the present study highlighted the possible risks to consumers of fish and fish products in the region that demand action to address this public health concern.

IMAGE COMPRESSION BASED ON WAVELETS WITH FRACTRAL COMPRESSION CODE
Archana Kajal,Ankita Gupta,Bhavana Singh,Anurag Kumar
International Journal of Advanced Technology & Engineering Research , 2012,
Abstract: This paper proposes to design a code and encoder that compresses a RGB image using fractal compression algorithm and Haar wavelet transform. This region-based fractal order utilizes the region edge map encoding scheme for resulting partition. In color quantisation a true color image is transformed into a color-mapped image consisting of K carefully selected representative colors. The goal of this quantization is to discard information, which is not visually significant.

Diagnostic Value of Polymerase Chain Reaction in Female Tuberculosis Leading to Infertility and Conception Rate After ATT
Suman Puri, Bhavana Bansal
JK Science : Journal of Medical Education & Research , 2009,
Abstract: To evaluate diagnostic value of PCR (Polymerase chain reaction) in female genital tuberculosis and tostudy conception rate after ATT (Anti tubercular treatment) in positive cases. Sixty infertile patients wereinvestigated for presence of Mycobacterium tuberculosis (MTB) by PCR of endometrial curettings. PCRdemonstrated MTB DNA in 28 patients. ATT was started in diagnosed cases which were followed up fortwo years for conception.All patients with laparoscopy suggestive of tuberculosis, more than 50% ofthose with a probable diagnosis and significant number of those with incidental findings were positive byPCR. Six PCR positive cases conceived within two years after taking ATT for 9 months. Four patientsconceived spontaneously and two patients with intrauterine insemination. PCR offered increased sensitivityin determining tuberculosis etiology in female infertility and significant number of patients conceived afterregular ATT.
Application of Coupled Fixed Point Technique in Solving Integral Equations on Modified Intuitionistic Fuzzy Metric Spaces
Bhavana Deshpande,Amrish Handa
Advances in Fuzzy Systems , 2014, DOI: 10.1155/2014/348069
Abstract: We establish a common coupled fixed point theorem for weakly compatible mappings on modified intuitionistic fuzzy metric spaces. As an application of our result, we study the existence and uniqueness of the solution to a nonlinear Fredholm integral equation. We also give an example to demonstrate our result. 1. Introduction The concept of fuzzy metric space has been introduced in several ways. In [1], Kramosil and Michalek introduced the concept of fuzzy metric space. Later on, it is modified by George and Veeramani [2] with the help of continuous t-norms and they defined the Hausdorff topology of fuzzy metric spaces. Atanassov [3] introduced and studied the concept of intuitionistic fuzzy sets as a generalization of fuzzy sets. Alaca et al. [4] using the idea of intuitionistic fuzzy sets defined the notion of intuitionistic fuzzy metric space with the help of continuous t-norms and continuous t-conorms as a generalization of fuzzy metric space due to Kramosil and Michalek [1]. In [5], Park generalized the notion of fuzzy metric space given by George and Veeramani [2] and introduced the notion of intuitionistic fuzzy metric space. Gregori et al. [6] pointed out that topologies generated by fuzzy metric and intuitionistic fuzzy metric coincide. In view of this observation, Saadati et al. [7] modified the notion of intuitionistic fuzzy metric and defined the notion of modified intuitionistic fuzzy metric spaces with the help of continuous t-representable. Bhaskar and Lakshmikantham [8] introduced the notion of coupled fixed point and mixed monotone mappings and gave some coupled fixed point theorems. As an application, they study the existence and uniqueness of solution for periodic boundary value problems. Lakshmikantham and Ciric [9] introduced the concept of coupled coincidence point and proved some common coupled fixed point theorems. Sedghi et al. [10] gave a coupled fixed point theorem for contractions in fuzzy metric space, which was further generalized by Hu [11]. In [12], Hu et al. improved, rectified, and generalized the result obtained in [11]. On the other hand, many scientific and engineering problems can be described by integral equations. Initial and boundary value problems can be transformed into Volterra or Fredholm integral equations. Integral equations can also be created by many mathematical physics models such as diffraction problems, scattering in quantum mechanics, conformal mapping, and water wave. Integral equations or integro-differential equations can be applied in science and engineering. Many areas that are described by
An Improved Robust Fuzzy Extractor
Bhavana Kanukurthi,Leonid Reyzin
Computer Science , 2008,
Abstract: We consider the problem of building robust fuzzy extractors, which allow two parties holding similar random variables W, W' to agree on a secret key R in the presence of an active adversary. Robust fuzzy extractors were defined by Dodis et al. in Crypto 2006 to be noninteractive, i.e., only one message P, which can be modified by an unbounded adversary, can pass from one party to the other. This allows them to be used by a single party at different points in time (e.g., for key recovery or biometric authentication), but also presents an additional challenge: what if R is used, and thus possibly observed by the adversary, before the adversary has a chance to modify P. Fuzzy extractors secure against such a strong attack are called post-application robust. We construct a fuzzy extractor with post-application robustness that extracts a shared secret key of up to (2m-n)/2 bits (depending on error-tolerance and security parameters), where n is the bit-length and m is the entropy of W. The previously best known result, also of Dodis et al., extracted up to (2m-n)/3 bits (depending on the same parameters).

Bhavana Godbole, Shyambihari Shrivastava, Deepti Jain, Vganesan Ganesan, Nitu Badera
Materials Sciences and Applications (MSA) , 2011, DOI: 10.4236/msa.2011.26088
Abstract: Transparent Zinc Oxide (ZnO) thin films having different thickness are prepared by using spray pyrolysis technique. Structural and morphological behavior has been studied by using atomic force microscopy and x-ray diffraction. The scaling behavior obtained by using height-height correlation method shows that, films with different thickness are developed under non-equilibrium condition behaves as self-affine surfaces. With the increase in thickness, the grain size as well as activation energy have found to be decreased.
