SILC-A Secured Internet Chat Protocol
ANINDITA SINHA,SAUGATA SINHA
International Journal of Advanced Research in Electrical, Electronics and Instrumentation Engineering , 2013,
Abstract: The Secure Internet Live Conferencing (SILC) protocol, a new generation chat protocol provides full featured conferencing services, compared to any other chat protocol. Its main interesting point is security which has been described all through the paper. We have studied how encryption and authentication of the messages in the network achieves security. The security has been the primary goal of the SILC protocol and the protocol has been designed from the day one security in mind. In this paper we have studied about different keys which have been used to achieve security in the SILC protocol. The main function of SILC is to achieve SECURITY which is most important in any chat protocol. We also have studied different command for communication in chat protocols.

Abstract: The present study is aimed at investigating the association between T833C/844ins68 polymorphism and MR. One hundred and ninety MR cases were recruited after psychometric evaluation. Hundred and thirty-eight control subjects, two hundred and sixty-seven parents of MR probands and thirty cardiovascular disorder (CVD) patients were included for comparison. Peripheral blood was collected after obtaining informed written consent. The T833C/844ins68 polymorphism was investigated by PCR amplification of genomic DNA and restriction fragment length polymorphism analysis, followed by statistical analysis.The genotypic distribution of the polymorphism was within the Hardy-Weinberg equilibrium. A slightly increased genotypic frequency was observed in the Indian control population as compared to other Asian populations. Both haplotype-based haplotype relative risk analysis and transmission disequilibrium test reveled lack of association of the T833C/844ins68 polymorphism with MR; nevertheless, the relative risk calculated was higher (>1) and in a limited number of informative MR families, preferential transmission of the double mutant from heterozygous mothers to the MR probands was noticed (χ2 = 4.00, P < 0.05).This is the first molecular genetic study of CBS gene dealing with T833C/844ins68 double mutation in MR subjects. Our preliminary data indicate lack of association between T833C/844ins68 polymorphism with MR. However, higher relative risk and biased transmission of the double mutation from heterozygous mothers to MR probands are indicative of a risk of association between this polymorphism with mental retardation.Cystathionine β-synthase (CBS) catalyzes the condensation of serine and homocysteine to form cystathionine and abnormality in CBS activity is manifested in two major clinical conditions, viz. hyperhomocysteinemia and homocystinuria. Insufficiency in CBS activity may lead to hyperhomocysteinemia [1], which is considered to be an independent risk factor for arteri

Abstract: Ionizing radiation is responsible for oxidative stress by generating reactive oxygen species (ROS), which alters the cellular redox potential. This change activates several redox sensitive enzymes which are crucial in activating signaling pathways at molecular level and can lead to oxidative stress induced inflammation. Therefore, the present study was intended to assess the anti-inflammatory role of ferulic acid (FA), a plant flavonoid, against radiation-induced oxidative stress with a novel mechanistic viewpoint. FA was administered (50 mg/kg body wt) to Swiss albino mice for five consecutive days prior to exposing them to a single dose of 10 Gy 60Co γ-irradiation. The dose of FA was optimized from the survival experiment and 50 mg/kg body wt dose showed optimum effect. FA significantly ameliorated the radiation induced inflammatory response such as phosphorylation of IKKα/β and IκBα and consequent nuclear translocation of nuclear factor kappa B (NF-κB). FA also prevented the increase of cycloxygenase-2 (Cox-2) protein, inducible nitric oxide synthase-2 (iNOS-2) gene expression, lipid peroxidation in liver and the increase of tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) in serum. It was observed that exposure to radiation results in decreased activity of superoxide dismutase (SOD), catalase (CAT) and the pool of reduced glutathione (GSH) content. However, FA treatment prior to irradiation increased the activities of the same endogenous antioxidants. Thus, pretreatment with FA offers protection against gamma radiation induced inflammation.

Abstract:

The Hydrochemical study was carried out in Dwarakeswar watershed area, Bankura and Purulia districts, West Bengal, India, with an objective of understanding the suitability of local groundwater quality for domestic and irrigation purposes. Groundwater samples have been collected from different villages within Dwarakeswar watershed area. The samples have been analysed to determine physical parameters like pH, EC, TDS and Hardness, the chemical parameters like Na, K, Ca, Fe, HCO3, SO4 and Cl. From the analysed data, some parameters like Sodium Absorption Ratio (SAR), Soluble Sodium Percentage (SSP), Residual Sodium Carbonate (RSC), Total Hardness (TH), Magnesium Absorption Ration (MAR) and Kelly’s Ratio (KR) have also been determined. The distribution pattern of TDS and chlorides, which are the general indicators of groundwater quality reveals that on an average the ground water is fresh and potable except the ground water in and around Teghari, Gara and Satyatan Primary school where the groundwater is not potable and may affect the health of local population because concentration of TDS exceeds the desirable limits of 500 mg/L. The aerial distribution of Total Dissolved Solids (TDS) reveals that highest concentration is recorded at Gara and Teghri and the lowest concentrations is noted in Suburdih and Kalabani. SAR values were ranged between 0.09 - 0.54 meq/L in pre monsoon and 0.01 - 0.24 meq/L in post-monsoon. It is evident from the whole sample set that the SAR value is excellent in all the samples. Hence, our findings strongly suggest that all the abstracted groundwater samples from the study area were suitable for irrigation. Results of analyses for physical and chemical parameters of groundwater in this area was found to be within the desirable Bureau of Indian Standards and World Health Organisation limits for drinking water.

Abstract: In the middle age, adjustment to developmental tasks will affect marital relationship. This study aimed to determine the cohesiveness of husband and wife who have entered middle adulthood, covering aspects of solidarity, marital satisfaction, interest, and affiliates and also the factors that affect the cohesiveness of husband and wife when the marriage age of 20 years or more. Subjects are three pairs of husband and wife who are legally married for over 20 years and each individual’s age between 40-60 years old. This qualitative research used the case study approach and collected data by semi-structured interviews and nonparticipant observation. The results showed that the cohesiveness of husband and wife owned in middle age is different in each pair. In the first couple showed low cohesion, high on the second couple, and medium for the third couple. In the third couple, there is a change before the peak of the conflict in mid-2011 by now. Factors that affect the cohesiveness of husband and wife in middle age is a social perception, social support, emotional regulation, a period of quiet in the middle ages, the intensity of togetherness, understanding of gender, temperament, and love.
Cryptic successors unrevealed even by network analysis: A comparative study of two paper wasp species

Abstract: Understanding queen succession could be a key contribution to the better understanding of the origins and evolution of eusociality. In order to investigate the nature of organizational changes during queen succession, we analyzed two closely related paper wasp species (Ropalidia cyathiformis and Ropalidia marginata). We compared the effects of in vivo and in silico queen removal on the structure of their interaction networks (the former resulting in queenless colonies with potential queens). We studied several structural measures. There is no major structural difference between full (queenright) and in silico queen-removed colonies but there are major differences between queenless and in silico queen-removed ones. This suggests that queen succession is accompanied by a major reorganization of the society, in Rm but not so much in Rc. We also analysed the centrality ranks of potential queens and found that their positional importance changes a lot during queen succession in R. marginata, as they are processed in the colony. In the queenright colonies of R. marginata, the direction of links is a better predictor of the identity of the potential queen than the strength of links.

Abstract: A clear protocol for synthesis of sequential reversible circuits from any particular gate library has been provided. Using that protocol, reversible circuits for SR latch, D latch, JK latch and T latch are designed from NCT gate library. All the circuits have been optimized with the help of existing local optimization algorithms (e.g. template matching, moving rule and deletion rule). It has been shown that the present proposals have lower gate complexities, lower number of garbage bits, lower quantum cost and lower number of feedback loops compared to the earlier proposals. For a fair comparison, the optimized sequential circuits have been compared with the earlier proposals for the same after converting the earlier proposed circuits into equivalent NCT circuits. Further, we have shown that the advantage in gate count obtained in some of the earlier proposals by introduction of New gates is an artifact and if it is allowed then every reversible circuit block can be reduced to a single gate. In this context, some important conceptual issues related to the designing and optimization of sequential reversible circuits have been addressed. A protocol for minimization of quantum cost of reversible circuit has also been proposed here.
