Segment Based Indexing Technique for Video Data File

AbstractA video is an effective tool to exchange the information in the structure of showing the brief text message due to the advance developed technology. Video capturing is effortless process but the related video retrieval is the difficult process, for that process the videos must be indexed. Retrieval is the method that retrieved a video using a user query. The query will be image or texts depend upon the query result output system that returned a particular video or image based on that query. In this project we create a indexing for video file by using segment based indexing technique. Here video will be divided into a hierarchy which is in storyboards of film making. For instance, a hierarchical based video search is composed into multi stage abstraction for assist the users to locate the specific video segments/frames logically. This paper brings out the reduced bandwidth and reduced delays the video through the network of searching and reviewing. Experimental results verify this

Thermal comfort properties of single jersey fabrics made from recycled polyester and cotton blended yarns

Thermal comfort properties of single jersey fabrics made from recycled polyester and cotton blended yarns have been studied. Single jerseys knitted fabrics are prepared with different recycled polyester blend ratios, linear density and loop lengths. Box and Behnken, a three level three variable factorial design technique has been used to study the interaction effects of the variables on the characteristics of fabrics. The influence of these variables on thermal comfort properties of fabrics is studied, their response surface equations are derived and design variables are optimized. Fabric becomes thinner, lighter and more porous with the increase in recycled polyester in blend ratio and loop length, whereas thicker, heavier and less porous fabric is resulted with the increase in linear density. Similarly, the increase of linear density results in thicker, heavier and less porous fabric with higher thermal conductivity, lesser air permeability and thermal resistance and high relative water-vapor permeability at medium linear densities. Loose structure results in thinner, lighter and more porous fabric with higher thermal resistance, air permeability and relative water-vapor permeability, and lesser thermal conductivity

PROTECTIVE EFFECT OF THYMOQUINONE ON THE LIVER TISSUES OF 7, 12-DIMETHYLBENZ (A) ANTHRACENE INDUCED EXPERIMENTAL BREAST CANCER RATS

Objective: Thymoquinone (TQ), the main active ingredient of the volatile oil isolated from the Nigella sativa seeds has been shown to possess a widearray of pharmacological effects. Recently, we have reported the anticancer potential of TQ in 7, 12-dimethylbenz (a) anthracene (DMBA) inducedrats. DMBA acts as a potent site and organ-specific carcinogen by generating various reactive metabolic intermediates leading to oxidative stress. Thepresent study was hypothesized to explore the protective effect of TQ against DMBA induced liver injury in rats.Methods: DMBA was used to induce breast cancer in rats. Oral treatment of TQ (25 mg/kg body weight) to DMBA induced rats daily for 4 weeks wasfound to be effective against DMBA induced mammary gland carcinogenesis in female Wistar rats. The levels of nucleic acids, oxidative stress markand antioxidants were determined. The activities of Phase I and Phase II enzymes, tricarboxylic acid (TCA) cycle enzymes were assayed.Results: The increased levels of DNA and RNA were found to be decreased on treatment with TQ. The altered activities of Phase I and Phase IIbiotransformation enzymes were found to be regulated on treatment with thymoqionone. The hepatoprotective nature of TQ was assessed byanalyzing the markers of oxidative stress, and antioxidant competence in DMBA induced rats. Treatment with TQ revealed a significant decline in thelevels of lipid peroxides, and a significant improvement in the levels of enzymatic and non-enzymatic antioxidants in the liver tissue. In addition, TQmodulated the activities of TCA cycle enzymes.Conclusion: The results of the present study clearly indicate that TQ protects the tissues from oxidative stress-mediated damage which is evidentfrom improved antioxidant status.Keywords: 7, 12-dimethylbenz (a) anthracene, Thymoquinone, Oxidative stress, Liver tissues, Antioxidant potential

Microwave assisted enzymatic kinetic resolution of (±)-1-phenyl-2-propyn-1-ol in nonaqueous media

Kinetic resolution of 1-phenyl-2-propyn-1-ol, an important chiral synthon, was studied through trans-esterification with acyl acetate to investigate synergism between microwave irradiation and enzyme catalysis. Lipases from different microbial origins were employed for the kinetic resolution of (R/S)-1-phenyl-2-propyn-1-ol, among which Candida antarctica lipase B, immobilized on acrylic resin (Novozym 435), was found to be the best catalyst in n-hexane as solvent. Vinyl acetate was the most effective among different acyl esters studied. The effect of various parameters was studied in a systematic manner. Definite synergism between microwave and enzyme was observed. The initial rate was improved around 1.28 times under microwave irradiation than conventional heating. Under optimum conditions, maximum conversion (48.78%) and high enantiomeric excess (93.25%) were obtained in 2 h. From modeling studies, it is concluded that the reaction follows the Ping-Pong bi-bi mechanism with dead end alcohol inhibition. Kinetic parameters were obtained by using nonlinear regression. This process is green, clean, and easily scalable as compared to the chemical process

Magnetization reversal in a site-dependent anisotropic Heisenberg ferromagnet under electromagnetic wave propagation

Abstract Information density and switching of magnetization offers an interesting physical phenomenon which invoke magneto-optical techniques employed on the magnetic medium. In this paper, we explore the soliton assisted magnetization reversal in the nanosecond regime in the theoretical framework of the Landau–Lifshitz–Maxwell (LLM) model. Starting from the Landau–Lifshitz equation, we employ the reductive perturbation method to derive an inhomogeneous nonlinear Schrodinger equation, governing the nonlinear spin excitations of a site-dependent anisotropic ferromagnetic medium under the influence of electromagnetic (EM) field in the classical continuum limit. From the results, it is found that the soliton undergoes a flipping thereby indicating the occurrence of magnetization reversal behavior in the nanoscale regime due to the presence of inhomogeneity in the form of a linear function. Besides, the spin components of magnetization are also evolved as soliton spin excitations

Ispaghula Husk-Based Extended Release Tablets of Diclofenac Sodium: Formulation, Evaluation and In vitro Release Studies

Purpose: To formulate extended-release tablets of diclofenac sodium based on ispaghula huskMethods: Tablets with varying proportions of diclofenac sodium and ispaghula husk were formulated by wet granulation technique at a fixed compression force of 10 kN. The formulated tablets were evaluated for physicochemical parameters as well as by Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and x-ray diffraction (XRD).Results: Content uniformity, weight variation, thickness and friability of the formulated tablets were within acceptable limits. The hardness of the tablet decreased from 5.4 to 4.2 kg/cm2 with increasing quantity of ispaghula husk in the formulation. In contrast, disintegration time increased from 12 to 70 min with increasing amount of husk. Tablets formulated with 1:0.25 and 1:0.5 drug/husk ratio failed to extend drug release whereas tablets prepared with 1:0.75 and 1:1 ratio extended release up to 5 and 6 h, respectively. FTIR, DSC and XRD analysis of tablets revealed the absence of diclofenac–ispaghula interaction and crystalline nature of diclofenac sodium. Drug release data fitted well with Korsmeyar-Peppas and the n value of 0.98 indicate non-Fickian diffusion. The tablets were stable on storage and retained its physicochemical properties within acceptable limits.Conclusion: The results indicate the possibility of formulating extended-release tablets based on ispaghula husk. The tablets were stable during storage and free from drug-excipient interactions. However further studies are required to ascertain the safety of the husk and to optimize the release properties of the tablets.Keywords: Ispaghula husk, Extended release tablet, Diclofenac sodium, Release kinetics
