Based on the security concern, plenty of crypto system constructed and applied on discrete applications to avoid the illegal process on ciphers. Let’s reminding the ethics of illegal technicians, it reflects a very big issue. To avoid these problems the padding on security mechanisms is needed to safe secrets. The proposed work entirely pointed out newly designed symmetric block cipher based crypto system to protect sensitive text documents. For preserving, prime numerals method is represented as P-3000 with multiple languages are implemented on the sensitive documents. Encrypted text appears as combination of international languages that would be polyphonic encoding. So that, polyphonic encoding chipper text is not considered as encrypted text by the intruder. Through this novel method, effective documents are transferred in a safety manner. The constructed outcome proved that provides strong security by the use of key generation by large prime numbers. Time analysis shows that the mechanism works as fast then the existing one.

Objective: The objective of this study is to know the diversity of arbuscular mycorrhizal fungi in the soil sites adjacent to Khouribga phosphate mines (Morocco)\nMethods: Soil samples were collected from two localities, Hattaneand Merah Lahrach, in Khouribga Region (Morocco) nearby two operated sites of phosphates extraction. Five samples were randomly taken from the surface horizon (0-20 cm) for each locality and a composite soil sample of 2 Kg was made for each site. Physicochemical soil analyzes were realized and the wet sieving method was used to highlight spores. The identification of the arbuscular mycorrhizal fungi was based on the morphological characters of the isolated spores from soil.\nResults: This study revealed the presence of a variety of endomycorrhizal fungi at sites adjacent to Khouribga phosphate mines (Morocco). 70 species of endomycorrhizal fungi belonging to 8 families (Glomaceae, Gigasporaceae, and Acaulosporaceae, Diversisporaceae, Pacisporaceae, Dentiscutataceae, Scutellosporaceae, Entrophosporaceae) and 3 orders (Glomerales, Gigasporales, Diversisporales) were found at the sites of Hattane and Merah Lahrach. The spore density is respectively 100 and 40 spores / 100 g of soil. Glomus, Acaulospora, and Gigaspora are the most dominant genera, while Scutellospora, Entrophospora, Funneliformis, Pacispora, Dentiscutata and Rhizophagus are the least represented genera.\nConclusion: This study has shown the richness of soils adjacent to mining sites on endomycorrhizal fungi. It would be interesting to exploit them in the development of a composite endomycorrhizal inoculum to be incorporated into a phospho-compost based on phosphate wastes and organic residues.

In recent environment web mining is an interactive medium to transfer information. Clustering plays vital role in data mining techniques. Data mining techniques could use to solve the information overload problems directly or indirectly. Biclique enumeration technique is used to be proven, scalable for processing large scale data in a reasonable amount of time. The experiment shows that the algorithm is scalable and efficient. The main disadvantage of relaxed biclique is time delay during the transfer of information. To overcome the above disadvantage, this paper proposed an inventive approach called effective biclique enumeration algorithm in web mining. The new approach of effective biclique enumeration improves the data transfer in a less time and in a high speed. Web mining is used to extract the exact information from the web which includes web pages [1], web links and web logs, etc. To provide faster retrieve and avoid overloading issue, this research paper has proposed a new approach using Effective Biclique Enumeration Algorithm (EBEA). The proposed research work is implemented in Weka tool with R-Programming Language and it is compared with Relaxed Biclique Enumeration Algorithm (RBEA).

The article presents a comprehensive analysis of the current state of the Russian Federation’s regions in terms of the created conditions for cooperation between research teams and the commercialization of scientists’ results of intellectual activity. The authors made an analysis of the estimated indicators, as well as the calculation of the integral index characterizing the given indicators. Case studies of the most developed regions are presented. The resulting conclusions can be the basis for the development of a regional environment that promotes scientific activity.

In this work, time-dependent diffusion equation is analyzed in two dimensions to calculate crosswind integrated normalized concentration of pollutants by using Laplace technique. Gaussian quadrature scheme is used to estimate the concentration by numerically inverting it when eddy diffusivity is varied in terms of convective scaling parameters in unstable case. Also a new model was proposed by using separation of variables to solve the diffusion equation in three dimensions, considering that the eddy diffusivity depends on the vertical height. Comparing between outcomes values with observed data of Sulfur hexafluoride (Sf6) on Copenhagen in Denmark (Gryning, 1984) in two dimensions are estimated. Comparisons between calculated, observed and previous work in three dimensions through neutral and stable conditions were carried out.

The subject of the study is the urban space of Togliatti – a large industrial center, the Soviet \"city of the future\", which was created in the last third of the 20th century as a single project. The article analyzes the concept of the Soviet \"city of the future\" from the point of view of modern provisions of environmental design. Creation features of \"city of the future\" Togliatti discusses in a period of ambitious construction projects in the USSR. The article analyzes the design installations for the formation of a comfortable environment, identifies ideas-resources that are incorporated in the concept of the Soviet industrial city for further modernization. Design tasks of formation of comfortable city environment are revealed of that time. These tasks are relevant in our time. The results of the study were the conclusions that demonstrate the promising urban ideas of the Soviet \"city of the future\" for the design of modern open urban spaces. For the first time the article substantiates the position that the industrial city in the style of Soviet architectural modernism was created as a single well-designed project.

In recent years, shooting games and VR contents have been increasing, which needs to simulate as real as possible that certainly can boost immersion. The latest FPS genre offers a variety of guns and bullets. However the gunshot wounds in graphics seem less realistic because they use stereotyped images of guns. The marks of the target\'s bullet should be differently observed and represented according to the features of the rifles and bullets. Therefore, we propose a method to synthesize a 3D bullet shape, based on terminal ballistic technology that considers wound ballistics rather than stereotyped images of a gun and bullet. To solve this, we design the cavity featured by ballistic coefficients using modified Bresenham’s line algorithm and 3d spline.

Let TPER be the tree corresponding to the weighted permutation graph G = (V,E). The eccentricity e(v) of the vertex v is defined as the sum of the weights of the vertices from v to the vertex farthest from v ∈ TPER. A vertex with minimum eccentricity in the tree TPER is called the 1-center of that tree. In an inverse 1-center location problem the parameter of the tree TPER corresponding to the weighted permutation graph G = (V,E), like vertex weights have to be modified at minimum total cost such that a pre-specified vertex s ∈ V becomes the 1-center of the permutation graph G. In this paper, we present an optimal algorithm to find an inverse 1-center location on the tree TPER corresponding to the permutation graph G = (V,E), where the vertex weights can be changed within certain bounds. The time complexity of our proposed algorithm is O(n), where n is the number of vertices of the weighted permutation graph G.

Advection-diffusion equation in two dimensions was estimated using the separation technique. This solution was calculated using different dispersion parameters (Brigg’s and Power law) to get the non-Gaussian crosswind integrated concentrations. The results of predicted model were compared with measuring observed data of Sulfur Hexafluoride SF6 on Copenhagen in Denmark.
