Visual Cryptography is a secret-sharing scheme that uses human visual system to perform complex computations. In this paper, first the background with the Visual Cryptography Scheme (VCS) has been established and the fundamental concepts have been explained. Then, a VCS algorithm has been presented to encode a grayscale image which uses a different approach from the traditional ones.

A Mobile Ad-Hoc Network (MANET) is a self-configuring network of mobile nodes connected by wireless links to form an arbitrary topology without the use of existing infrastructure. Since MANETs are not currently deployed on a large scale, research in this area is mostly simulation based. Among other simulation parameters, the mobility model plays a very important role in determining the protocol performance in MANET. Thus, it is essential to study and analyze various mobility models and their effect on MANET protocols. In this paper, we study different mobility models proposed in the recent research literature and their performance of routing protocols Bellman Ford, Dynamic Source Routing (DSR), WRP and Location Aided Routing (LAR1). In this study we have considered three mobility scenarios: Random Waypoint, Group Mobility and Freeway Models. These three Mobility Models are selected to represent possibility of practical application in future.Keywords

PURPOSE- To evaluate the causative etiology of pelvic adnexal masses by laparoscopy and to study correlation of findings on clinical examination with that of ultrasound and compare it with findings of diagnostic laparoscopy in patients with pelvic adnexal masses.
METHODOLOGY- The present study was conducted in department of Obstetrics and Gynaecology in Kasturba Hospital, Delhi over a period of 2 years (2012-2014). 50 patients with any gynaecological complaint and with suspected pelvic adnexal mass (group 1) and 50 asymptomatic patients with normal pelvic examination (Group 2) coming for laparoscopic sterilization were taken up for the study. Pelvic examination, ultrasonography and laparoscopy were done in all patients.
RESULTS: On diagnostic laparoscopy, 48(96%) patients had abnormal findings. In group 1, majority of adnexal masses 14 cases (28%) were found to be ovarian cyst. Polycystic ovaries were found in 10 (20%) cases. Endometriotic cyst was detected in 7 cases. Chronic pelvic inflammatory disease (6 cases of tuboovarian mass and 5 cases of hydrosalpinx) was found in 11 cases (22%). No abnormality was found in 2 (4%) cases. 23(46%) cases had adnexal mass on clinical examination and 36 (72%) had positive USG findings in group1. All the cases which had normal laparoscopic findings were also found to have normal clinical and ultrasound findings. In group 2 all 50 patients had normal clinical and ultrasound examination, but only 5(10%) cases had abnormal findings on laparoscopy). The sensitivity of pelvic examination, diagnose the pelvic adnexal mass was 43.34% and that of ultrasonography was 67.9%.
CONCLUSION: Laparoscopy triumphs in detecting many pelvic adnexal masses which clinical methods and USG sometimes fail to identify. This enforces position of laparoscopy as a gold standard for the evaluation of patients with pelvic adnexal masses.

Densities(ρ), Viscosities(η) and ultrasonic velocities(u) of binary mixtures of Benzonitrile with 1-propanol were determined using bicapillary pyknometer, Ostwald's Viscometer and ultrasonic interferometer respectively in temperature range of 298.15 to 318.15 K at intervals of 10K. The excess molar volume (VE), excess viscosities (ηE), excess Gibbs free energy of activation of viscous flow (G*E), excess isentropic compressibility (KSE), excess internal pressure (πiE) and excess enthalpy (HE) have been calculated from the experimental values of ρ, η and u. The results are discussed to explain the strength of interactions between component molecules in the binary mixture taken for study. The data was correlated by using Redlich-Kister polynomial equation stating their dependence on temperature and composition of the mixtures. These properties are used to illustrate the nature of interaction between component molecules.Full Text

Rapid industrialization and urbanization have increased air pollution, which poses a serious threat to human life. In megacities, the number of patients suffering from cardiovascular and respiratory diseases have increased rapidly. Face mask can be used for protection from outdoor air pollution, but indoor air quality can only be maintained through expensive, energy-inefficient air filtration devices. In the present study, nanofibrous polyacrylonitrile (PAN) filters encapsulated with titanium dioxide (TiO2) nanoparticles were developed using the electrospinning technique. The filters are porous and nearly transparent and therefore do not resist sunlight and airflow. Field testing of the PAN : TiO2 filters was done against the real aerosol particles and laboratory testing was done against ammonium sulphate particles. The field test results showed efficiency of about ~81% against total suspended aerosol particles (TSPM) and ~75% against laboratory generated particles. The TiO2 nanoparticles have been reported to kill the influenza virus and may help minimize an individual’s exposure to many harmful microbes due to their antimicrobial propertiesKeywords
