Identification of novel single nucleotide polymorphism (SNP) in DPB1 gene in ethnic population from West Bengal

HLA-DP antigens present peptides to CD4+ T cells and play an important role in autoimmune diseases and parasitic infections. We have sequenced HLA-DPB1 exon-2 from the ethnic populations in West Bengal, India and report a novel single nucleotide polymorphism (SNP) - rs111221466. The rs111221466 SNP induced silent mutation from CGA (Arg) to TGA (Stop Codon) and showed a frequency of 83.24%. In conventional sense, the frequency of novel SNP is very high. We have sequenced HLA-DPB1 exon-2 from a Bengali Population in West Bengal, India.

A Novel Approach Based on Decreased Dimension and Reduced Gray Level Range Matrix Features for Stone Texture Classification

The human eye can easily identify the type of textures in flooring of the houses and in the digital images visually.  In this work, the stone textures are grouped into four categories. They are bricks, marble, granite and mosaic. A novel approach is developed for decreasing the dimension of stone image and for reducing the gray level range of the image without any loss of significant feature information. This model is named as “Decreased Dimension and Reduced Gray level Range Matrix (DDRGRM)” model. The DDRGRM model consists of 3 stages.  In stage 1, each 5×5 sub dimension of the stone image is reduced into 2×2 sub dimension without losing any important qualities, primitives, and any other local stuff.  In stage 2, the gray level of the image is reduced from 0-255 to 0-4 by using fuzzy concepts.  In stage 3, Co-occurrence Matrix (CM) features are derived from the DDRGRM model of the stone image for stone texture classification.  Based on the feature set values, a user defined algorithm is developed to classify the stone texture image into one of the 4 categories i.e. Marble, Brick, Granite and Mosaic. The proposed method is tested by using the K-Nearest Neighbor Classification algorithm with the derived texture features.  To prove the efficiency of the proposed method, it is tested on different stone texture image databases.  The proposed method resulted in high classification rate when compared with the other existing methods

Population structure and genetic differentiation among the substructured Vysya caste population in comparison to the other populations of Andhra Pradesh, India

The present paper focuses on the study of the patterns of genetic microdifferentiation among one of the substructured caste populations of Andhra Pradesh, namely Vysya, with reference to 17 other Telugu speaking populations from the same region of India. A total of 302 individuais from the three Vysya subgroups (101 of Arya Vysya, 100 from Kalinga Vysya and 101 from Thrivarnika) were typed in 17 blood groups and protein polymorphisms. Nei's gene diversity analysis, as well as neighbour-joining tree and UPGMA cluster diagrams, derived from standard genetic distances, R-matrix analysis and a regression model for investigating the patterns of external gene flow and genetic drift due to isolation under the island model, were done at two levels: (1) considering only the three Vysya populations and (2) considering common loci among 20 populations of Andhra Pradesh. Seven of the 17 systems investigated were found to be monomorphic among all the three Vysya groups. The UPGMA tree and bidimensional scaling of the D2 distances derived from R-matrix analysis show a very distinct cluster of Vysya populations. Application of the model of regression of average heterozygosity versus the distance of populations from the centroid shows the three Vysya populations placed as clear outliers above the theoretical regression line. Different approaches employed in this study give support to the hypothesis of different origin and/or demographic story for the three Vysya groups compared with other populations of Andhra Pradesh.Fil: Lakshmi, N..

Powerful Mechanism To Avoid Denial Of Service Attack For Providing Data Security Using Software Puzzle

Network is a gathering of hubs that interrelate with each other for switch over the data. This data is vital for that hub is saved secretly. Attacker in the framework may catch this private data and twisted. So security is the real issue. There are a few security Attacks in network. One of the real scares to web analyze is DDoS Attack. It is a vindictive push to suspending or suspends administrations to destination hub. – Denial of administrations (DOS) and Distributed Denial of administrations (DDoS) are the significant issue against network security and digital security that permit a customer to perform exceptionally costly and key operations, before the network administrations are given to the regarded customer. However An Attacker might have the capacity to control the DOS and DDOS or implicit illustrations preparing Unit (GPU) and have the capacity to crush customer perplexes. In this paper we concentrate how to safeguard DOS and DDOS Attacker for being controlling the puzzlesolving strategies. So now we present another customer riddle alluded to as Software Puzzle. It is not at all like past riddle, which produce their riddle calculations ahead of time, a riddle calculation in the present programming riddle plans is haphazardly created simply after a customer solicitation is gotten from the server side. t the Denial-of-administration and disseminated DoS Attack a customer riddle strategy is actualized. Keeping in mind the end goal to avert further Attack in network and to improve the security the solicitation that is given by the customer and the document sent by the server to customer is in scrambled structure. One downside of existing framework is if the assailant distinguishes the port, he can barge in or meddle in the correspondence and surge DOS Attack and can hack conveying information. The strategy utilized is clarified as takes after. To start with the customer needs to explain a riddle produced by the server. At that point the customer checks the inactivity of the document that must be gotten to from server database. The customer can test the inactivity of the server by inputting the comparing server IP address, number of bundles, and the length of information in bytes. In the wake of handling the inactivity checking parameters, ping measurements of the server and the rough round excursion the reality of the situation will become obvious eventually shown in the outcome. The customer then encodes the solicitation and sends the solicitation to server. AES Algorithm is utilized to play out the encryption and decoding. The server after getting the solicitation needs to unscramble the solicitation utilizing the customer port number and IP address. The server sends the asked for record by encoding the document. At last the customer gets the record, unscrambles the substance and read it. Subsequently it can be inferred that more solid correspondence can be performed amongst server and customers and dynamic interchanges stays unaffected even within the sight of DDoS Attacks

Mixed Convection at a Vertical Plate in a Porous Medium with Magnetic Field and Variable Viscosity

A numerical study of a mixed convection boundary layer flow on a vertical plate in a porous medium with magnetic field, variable wall temperature and variable viscosity is made in this paper using the Darcy model. A free stream that varies as a power function of distance along the plate is assumed to flow parallel to the plate. Similarity solutions are obtained for the problem for both assisting flow and opposing flow. In the opposing flow case dual solutions are obtained for certain values of the parameters, and occurrence of boundary layer separation is also observed. Significant differences are observed between the behaviors of the two solutions of the dual solution case. Critical values of the mixed convection parameter are also obtained beyond which there exists no solution for the problem. Some of the observations of the analysis are - the range of values of the mixed convection parameter over which solutions exist for the problem is more in the presence of magnetic field than in its absence and also in the variable wall temperature case than in the isothermal case. Both local drag coefficient and heat transfer coefficient assume only positive values in the isothermal case while they assume both positive and negative values in the varying wall temperature case. Drag is less in the presence of magnetic field than in its absence and also in the isothermal case than in the varying wall temperature case. Heat transfer coefficient diminishes in the absence of magnetic field than in the presence of magnetic field

Sexual Risk Behaviour among Migrant Tribals Living in Urban Slums of an Eastern Indian City: Implications on the Spread of HIV

This paper reports the sexual risk behaviour among migrant tribal community living in an eastern Indian city. The age at marriage is very low in this community and 54% of women had first intercourse before the age of 15 years with the mean of 15.8 years and it is 19.5 years for men. Pre and extramarital relations, including multi-partnered sex is prevalent. Safe sexual practices are not reported and the risk perception is very low. High prevalence of behavioral risk factors leaves a potential risk for rapid spread of human immunodeficiency virus (HIV) both in slums as well as in remote tribal areas

Opportunity for natural selection among three endogamous subpopulations of Andhra Pradesh

The Crow′s index of opportunity for natural selection has been calculated for three endogamous subpopulations namely Arya Vysya, Thrivarnika and Kalinga Vysya of North Coastal Andhra Pradesh. The total index is in the order Arya Vysya > Thrivarnika > Kalinga Vysya. However, the mortality component is more in Kalinga Vysya, reflecting the poor medical facilities available to them due to their low socio- economic profile compared to other two populations. The results of the present study are compared with those among the other caste populations of Andhra Pradesh

Association of Alcohol Consumption and Blood Pressure in Some Low Socioeconomic Groups from Andhra Pradesh, India

The present paper examines the relationship of alcohol consumption with blood pressure (BP) levels and hypertension prevalence. Data on BP, alcohol consumption and anthropometry were obtained from a cross sectional sample of 1316 adult men and women of six low socioeconomic groups belonging to four different ethnic groups from Visakhapatnam district of Andhra Pradesh, India. Considerable proportions of respondents reported the consumption of alcohol. Some groups recorded higher levels of systolic and diastolic BP among alcohol drinkers than non-drinkers, and in others it was reverse. There was no uniform association between alcohol consumption and hypertension prevalence, though the combined data revealed a higher prevalence of hypertension among non-drinker men and drinker women. The present study population was a heterogeneous group in terms of alcohol consumption, and many of them were occasional drinkers. The study revealed no consistent association of alcohol consumption with blood pressure. The study opines that it is necessary to take measures to reduce the prevalence of alcohol consumption, as it was an underlying social problem and, though not directly associated with blood pressure; and alcohol consumption has been demonstrated as a major risk factor for cardiovascular diseases
