    Changes or alterations in biochemical composition take place due to various reasons viz., the natural conditions, spoilage and processing which in turn depends on the type and quality of the fish in question

    Women's View in Street and Lamenting Songs

    Get PDF
    Lamenting songs are one of the genres in Tamil literature. Music is intertwined in the life of the village people. Lamennting songs are sung to express the feeling of sorrow that arises in one's heart when a mother, father, husband, child, sibling or relative dies. People who do not know about the history of the dead people they can learn about the dead person’s history through those songs. A musical instrument known as Roar is played in death house. The sound of roar announces the death news in society. The same custom is seen in the streets. The street songs are intertwined with the roar music. This article brings out the hidden lamenting songs of street artists. In addition, we see that the relationship between the artists and the context of the story is revealed through comparison. Also, dictionary description of lamenting, lamenting in literature, structure of street songs is described in this article

    Backward whirl in a simple rotor supported on hydrodynamic bearings

    Get PDF
    The asymmetric nature of the fluid film stiffness and damping properties in rotors supported on fluid film bearings causes a forward or a backward whirl depending on the bearing parameters and the speed of the rotor. A rotor was designed to exhibit backward synchronous whirl. The rotor-bearing system exhibited split criticals, and a backward whirl was observed between the split criticals. The orbital diagrams show the whirl pattern

    Forecasting milk production in Tamilnadu

    Tamilnadu, with a daily milk production of 145.88 lakh litres, is one of the leading states in milk production in India. And the Tamilnadu milk cooperatives play a major role in the development dairy within the state. This study aims at forecasting milk production in Tamilnadu, based on data on milk production during the years from 1978 to 2008. The study considered Autoregressive (AR), Moving Average (MA) and Autoregressive Integrated Moving Average (ARIMA) processes to select the appropriate stochastic model for forecasting milk production in Tamilnadu. Based on ARIMA (p, d, q) and its components ACF, PACF, Normalized BIC, Box-Ljung Q statistics and residuals estimated, ARIMA (1, 1, 0) was selected. Based on the chosen model, it could be predicted that the milk production would increase to 7.15 million tons in 2015 from 5.96 million tons in 2008 in Tamilnadu

    Turbulence in non-integer dimensions by fractal Fourier decimation

    Full text link
    Fractal decimation reduces the effective dimensionality of a flow by keeping only a (randomly chosen) set of Fourier modes whose number in a ball of radius kk is proportional to kDk^D for large kk. At the critical dimension D=4/3 there is an equilibrium Gibbs state with a k5/3k^{-5/3} spectrum, as in [V. L'vov {\it et al.}, Phys. Rev. Lett. {\bf 89}, 064501 (2002)]. Spectral simulations of fractally decimated two-dimensional turbulence show that the inverse cascade persists below D=2 with a rapidly rising Kolmogorov constant, likely to diverge as (D4/3)2/3(D-4/3)^{-2/3}.Comment: Submitted to Phys. Rev. Lett. 4 pages, 3 figure

    Travel Package Recommendation

    Get PDF
    Location Based SocialNetworks (LBSN) benefit the users by allowing them to share their locations and life moments with their friends. The users can also review the locations they have visited. Classical recommender systems provide users a ranked list of single items. This is not suitable for applications like trip planning,where the recommendations should contain multiple items in an appropriate sequence. The problem of generating such recommendations is challenging due to various critical aspects, which includes user interest, budget constraints and high sparsity in the available data used to solve the problem. In this paper, we propose a graph based approach to recommend a set of personalized travel packages. Each recommended package comprises of a sequence of multiple Point of Interests (POIs). Given the current location and spatio-temporal constraints, our goal is to recommend a package which satisfies the constraints. This approach utilizes the data collected fromLBSNs to learn user preferences and also models the location popularity

    Jason T Lerner1, Noriko Salamon2, Raman Sankar1,31Departments of Pediatrics, 2Radiological Sciences, 3Neurology, David Geffen School of Medicine, University of California Los Angeles and Mattel Children’s Hospital at UCLA, Los Angeles, CA, USAAbstract: Vigabatrin, the first therapeutic agent to be approved by the Food and Drug Administration for the treatment of infantile spasms, as well as for adjunctive use in the treatment of refractory complex partial epilepsy, represents an important advance for patients with difficult-to-manage epilepsy. This review summarizes the complex history, chemistry, and pharmacology, as well as the clinical data leading to the approval of vigabatrin for infantile spasms in the US. The long path to its approval reflects the visual system and white matter toxicity concerns with this agent. This review provides a brief description of these concerns, and the regulatory safety monitoring and mitigation systems that have been put in place to enhance benefit over risk.Keywords: vigabatrin, infantile spasms, monotherap

    Existence of global and explosive mild solutions of fractional reaction-diffusion system of semilinear SPDEs with fractional noise

    Full text link
    In this paper, we investigate the existence and finite-time blow-up for the solution of a reaction-diffusion system of semilinear stochastic partial differential equations (SPDEs) subjected to a two-dimensional fractional Brownian motion given by {du1(t,x)=[Δαu1(t,x)+γ1u1(t,x)+u21+β1(t,x)]dt+k11u1(t,x)dB1H(t)+k12u1(t,x)dB2H(t),du2(t,x)=[Δαu2(t,x)+γ2u2(t,x)+u11+β2(t,x)]dt+k21u2(t,x)dB1H(t)+k22u2(t,x)dB2H(t),\left\{\begin{aligned} du_{1}(t,x)&=\left[ \Delta_{\alpha}u_{1}(t,x)+\gamma_{1}u_{1}(t,x)+u^{1+\beta_{1}}_{2}(t,x) \right]dt +k_{11}u_{1}(t,x)dB^{H}_{1}(t)+k_{12}u_{1}(t,x)dB^{H}_{2}(t), \\ du_{2}(t,x)&=\left[ \Delta_{\alpha}u_{2}(t,x)+\gamma_{2}u_{2}(t,x)+u^{1+\beta_{2}}_{1}(t,x) \right]dt+k_{21}u_{2}(t,x)dB^{H}_{1}(t)+k_{22}u_{2}(t,x)dB^{H}_{2}(t), \\ \end{aligned}\right. for xRd, t0x \in \mathbb{R}^{d},\ t \geq 0, along with ui(0,x)=fi(x),xRd,\begin{array}{ll} u_{i}(0,x)=f_{i}(x), &x \in \mathbb{R}^{d}, \nonumber\\ \end{array} where Δα\Delta_{\alpha} is the fractional power (Δ)α2-(-\Delta)^{\frac{\alpha}{2}} of the Laplacian, 0<α20<\alpha \leq 2 and βi>0, γi>0\beta_{i}>0,\ \gamma_{i}>0 and kij0,i,j=1,2k_{ij}\neq 0, i,j=1,2 are constants. We provide sufficient conditions for the existence of a global weak solution. Under the assumption that β1β2>0\beta_{1}\geq \beta_{2}>0 with Hurst index 1/2H<1, 1/2 \leq H < 1, we obtain the blow-up times for an associated system of random partial differential equations in terms of an integral representation of exponential functions of Brownian motions. Moreover, we provide lower and upper bounds for the finite-time blow-up of the above system of SPDEs and obtain the lower and upper bounds for the probability of non-explosive solutions to our considered system
