    Security has gained a lot of importance as information technology is widely used. The main issue in visual cryptography is quality of reconstructed image. This problem is overcome by using “Secured Lossless share Watermarking ”. In this method the quality of reconstructed image is higher and the security of share is high compare with conventional visual cryptographic scheme. The secret image is converted into. Each share is embedded to different carrier images. Invisible watermarking method is used for embedding carrier image and shares. For security, the invisible watermarked shares are then encrypted, AES modified encryption method is used. The encrypted shares are send to other participants. At the receiver end receiving the shares and decrypt the shares, then combining these shares together reveal the secret. The quality of rejoined shares and original secret shares are almost same.

    Prameha is burning problems of the decade. According to the latest data from World Health Organization, a Global estimate of 422 million adults is living with Prameha. It belongs to the category of chronic Non-Communicable Diseases (NCD) Prameha more specifically Madhumeha can be correlated to the features of Diabetes mellitus. Considering the etiology of Diabetes mellitus, Stress has been found to have a prime place. It not only acts as an etiological factor but also as a triggering factor. Today stress has become an inevitable part of modern life. In today’s materialistic world, there is unhealthy competition in every field and man is compelled to act like a machine. This deteriorates the equilibrium of mind and the person comes under the influence of stress

    Subsidies in Indian fisheries-Methodological issues and implications for the future

    Get PDF
    Subsidies are financial contributions made by Government or public bodies which provide a private benefit. Westlund (2003) defined fisheries subsidies as “government actions or inactions that are specific to the fisheries industry and that modify – by increasing or decreasing – the potential profits by the industry in the short, medium or long-term”. World attention was drawn to the scale of the global fisheries crisis and also the extent of fishery subsidies in 1992 with the publication of an FAO report, Marine Fisheries and the Law of the Sea: A Decade of Change. The adverse effect of subsides depend on the existing management regime and the bioeconomic conditions of the fishery. Subsidies lower the cost of harvest and raise the effective price of fish. As a management tool, cost-reducing or profit-increasing subsidies may result in increased productive efforts and hence considered as harmful through over exploitation of fish resources and unsustainable harvesting

    Constraint analysis on the impediments faced by Indian seafood exporters

    Among the leading non traditional exports, fish and fishery products play a prominent role contributing significantly to the success of India's export effort to bridge the yawning trade gap of India.They have become one of the major foreign exchange earners in the agricultural and a1lied sectors of India in the recent years. Starting from mere scraps in the pre independence period, it is a saga of steady striking and sustained growth that the industry had recorded raising India's status and prestige and securing for her a respectable position among the maritime nations of the worl

    The study was aimed to assess the breastfeeding practices among mothers of infants in Peringara Gramapanchayat in Kerala. Study was a community based cross-sectional study among mothers of infants in Peringara gramapanchayat using a pretested questionnaire. 142 breastfeeding mothers of infants in Peringara gramapanchayat were studied and mothers who were not present at home during the study were excluded from the study. Study period consisted of 18 days between December 2015 and January 2016. Study variables includes type of delivery, initiation of breastfeeding, breastfeeding practices and role of ASHAs in promoting good breastfeeding practices. Statistical analysis was done using Pearson’s Chi-square test and T test. The study found that exclusive breastfeeding has been done by 68.3% of mothers. There is no practice of giving pre-lacteal feed, 95.8% of mothers have given colostrum to the new born. Statistically significant association was found between the type of delivery and time of initiation of breastfeeding (p< 0.05). Time of initiation of breastfeeding was prolonged in case of Caesarean section. 49.3% of mothers have breastfed the baby within one hour. 55.6% of mothers were informed about importance of breastfeeding by ASHAs and only 20.4% of mothers were informed about period of exclusive breastfeeding and period of complimentary feeding by ASHAs

    Background: Breast engorgement is a major issue in the early postpartum period under the influence of hormonal shift and increase milk production. The purpose of this study was to evaluate the prevention, recognition and management of breast engorgement.Methods: Quasi Experimental, quantitative study conducted in AIMS, Kochi among sixty mothers by Convenience sampling technique. The design used was pre-test post-test control group design. A semi structured knowledge questionnaire, Bristol Breastfeeding Assessment Tool and an Observational checklist were used to collect the data. Prenatal teaching provided to the Experimental group.Results: The mean pre-test knowledge level of control group was 9.83 and the post-test knowledge was 10.03. In the Experimental group, the mean pre-test level was 10.20 and the post-test level is 20.76. The ‘t’ value of control group was 0.71 and that of Experimental group was 12.83 which was highly significant at 0.001 level. There was a significant increase in knowledge score in Experimental group. Comparing the breastfeeding practices regarding positioning and attachment in both groups, showed a significant difference at the level of 0.001 but other two aspects, sucking and swallowing were not significant. Comparing the incidence, 13.3% mothers reported in experimental group whereas 63.3% in the control group, which showed a remarkable decrease in the incidence of breast engorgement in the former group.Conclusions: The prenatal teaching was effective in improving the health of mothers as well as practices of breastfeeding and it helped in reduction of the incidence of breast engorgement

    The dynamics of fibers dispersed in viscoelastic turbulent flows

    This study explores the dynamics of finite-size fibers suspended freely in a viscoelastic turbulent flow. For a fiber suspended in Newtonian flows, two different flapping regimes were identified previously by Rosti et al (2018). Here we explore, how the fiber dynamics is modified by the elasticity of the carrier fluid by performing Direct Numerical Simulations of a two-way coupled fiber-fluid system in a parametric space spanning different Deborah numbers, fiber bending stiffness and the linear density difference between fiber and fluid. We examine how these parameters influence various fiber characteristics such as the frequency of flapping, curvature, and alignment with the fluid strain and polymer stretching directions. Results reveal that the neutrally-bouyant fibers, depending on their flexibility, oscillate with large and small time scales transpiring from the flow, but the smaller time-scales are suppressed as the polymer elasticity increases. Polymer stretching is uncommunicative to denser-than-fluid fibers, which flap with large time scales from the flow when flexible and with their natural frequency when rigid. Thus, the characteristic elastic time scale has a subdominant effect when the fibers are neutrally-bouyant, while its effect is absent when the fibers become more inertial. Additionally, we see that the inertial fibers have larger curvatures and are less responsive to the polymer presence, whereas the neutrally-bouyant fibers show quantitative changes. Also, the neutrally-bouyant fibers show a higher alignment with the polymer stretching directions compared to the denser ones. In a nutshell, the polymers exert a larger influence on neutrally-bouyant fibers compared to the denser ones. The study comprehensively addresses the interplay between polymer elasticity and the fiber structural properties in determining its response behaviour in an elasto-inertial turbulent flow
