Secure Data Sharing Model for Cloud Computing (SSCC) is a new cryptosystem model that aims to store user's data files in a secure manner to keep it away from the unauthorized access. We have developed a new cryptosystem model that based on the Original Hill cipher algorithm using matrices manipulation and symmetric key cryptography. It gave a good impression by comparing it with previous ways where the comparing results between SSCC and Hill Cipher 6.86% improvement in the encryption time. While when we compare SSCC and Advance Encryption Standard (AES) the difference was 3.94% for AES which means that the proposed model has a chance to compete with AES model. Another comparison is done to cover the two cases: SSCC1 and SSCC2, the SSCC1 with and without compression decreasing the encryption time in a percentage of 96.287%.

Reinforced concrete frames structures with unreinforced masonry infill walls are prevailing in developing countries like India with regions of high seismicity. The aim of this study is to compare different response parameter on the effect of different masonry infill materials for reinforced concrete frames . For this purpose G+14 RC framed building were model with different infill materials and Response spectrum method has been executed for the analysis as per IS1893:2002 using Etabs software. The variation of base shear, storey drift, and displacement were obtained by the analysis of three RC frame models viz. bare frame, in-filled frame and open first storey frames were carried out. For modelling of infill wall, Equivalent diagonal strut method is used to find out the width of strut using FEMA approach. The results are compared and shown in the form of graphs. The results show that with addition to opening, hollow concrete block and fly ash brick frame in-filled models exhibit superior seismic behaviour.

Simple chemical bonding method to synthesize cyclodextrin–chitosan/nano graphene oxide (CCGO) was reported. The adsorption behaviors of Cu(II) in aqueous solution on CCGO were systematically investigated. The procedure is based on the selective formation of Cu(II) at optimum pH by elution with organic eluents and determination by flame atomic absorption spectrometry. The method is based on complex formation on the surface of the ENVI-18 DISKTM disks modified cyclodextrin–chitosan/nano graphene oxide (CCGO) followed by stripping of the retained species by minimum amounts of appropriate organic solvents. The elution is efficient and quantitative. The effect of potential interfering ions, pH, CCGO amount, stripping solvent, and sample flow rate were also investigated. Under the optimal experimental conditions, the break-through volume was found to about 1000mL providing a preconcentration factor of 600. The maximum capacity of the disks was found to be 398± 3 µg for Cu2+.The limit of detection of the proposed method is 5ng per 1000mL.The method was applied to the extraction and recovery of copper in different water samples.

In this article we apply Moore- Penrose generalised inverse method to solve a fully fuzzy linear system. By this method we obtain the solution of fully fuzzy linear system of equations in the case of Trapezoidal fuzzy number matrices. A numerical example is also given.

Let G (V, E) be a graph with vertex set V= V(G) and edge set E= E(G) of order p and size q. 0 –edge magic labeling[4], 1-edge magic labeling[7] and n-edge magic was introduced and extended by [6, 9,10].This article discussed and found generalisation of order and size n- edge magic labeling of special graphs such as caterpillar graph, MÖubius- Kantor graph, Hypercube graph, etc,.

Spermatocytic seminoma (SS) is a distinct testicular germ cell tumor, representing less than 1% of testicular cancers. The clinical features that distinguish (SS) from classical seminoma (CS) are an older age at presentation and a reduced propensity to metastasize. Currently, the management (SS) has changed to the increased use of surveillance, provided that there are no risk factors which may predict recurrence. Here, we report an additional case of SS and present a comprehensive relevant literature review concerning current clinical, histopathological, and therapeutic features.

Let denote the set of all complex matrices .By the star partial ordering .So means that and . We find several characterizations for in the case of s-k normal matrices. As an applications, we study how relates to . The results can be extended to study how relates to , where is an integer.

Almost every high educational system or university offers variety type of co-curriculum activities such academic clubs, music and entertainment, recreation and sports. These activities offer opportunities for students to learn the values of individual and group responsibility teamwork, physical strength and endurance, a sense of culture and community competition. After all, every high educational system or university should be seen as a transformative experience which students can prepare themselves to succeed in varied roles they will undertake in future life. Co-curriculum was constructed by the student as a central focus. Co-curriculum may be referred to as a planned or organised guild base to execute or carryout teaching and learning process, it relate to the entire process of educational system, school and society. Co-curriculum activities provide a channel for reinforcing the lessons learned not only in the classroom, at the same time student have the ability to apply academic skills in a real-world context, and thus considered part of a well-rounded education.

Present communication deals with some biochemical parameters i.e. glycogen, proteins and lipids were estimated in normal, infected intestine and their relevant four species of pseudophyllidean tapeworm Senga Dollfus, 1934 viz. S. satarensis Bhure et. al., 2011, S. madhavae Bhure et.al., 2011, S. mangalbai Bhure et.al., 2011 and S.microrostellata Bhure et.al., 2013. The non-infected intestine contains more glycogen, protein and lipids as compared to infected intestine, whereas low biochemical content in all the species of the genus Senga. The intestinal parasites were capable of extracting nutritious materials from their host and thus represented a high level in glycogen, protein and lipid.

The mixed-ligand complex of [Cu(bipy)2S8(ClO4)2 was synthesized and characterized by employing elemental analyses, metal analyses, infrared and UV-Vis spectroscopy, room temperature magnetic susceptibility measurements, conductivity measurements and theoretical studies. The elemental and metal analyses show good agreement which support the formulation for the complex. The Cu-S band in the infrared spectrum at 465 cm -1, indicate the formation of the complex. The UV-Vis spectra shows different intraligand transitions at 49,505 cm-1 , 33,445 cm-1, 32,467 cm-1 and the bands at 13,661 cm-1 with a shoulder at 11,820 cm-1 in the visible region supported the CHN data for the formation of the five-coordinate complex. The magnetic moment value at 1.40 B.M indicates the presence of a strong antiferromagnetic properties of the complex. A 1:2 electrolyte nature of the complex was revealed in the conductivity value of 179 mho cm2 mol-1. The theoretical calculations predicted a distorted square pyramidal with S8 in the apical position for the complex with Cu(II)-S bond distance calculated to be 2.874 Å and 2.199 Å for PM3 and DFT methods respectively. The low negative value of S.E (–1.58 kcal/mol) calculated for [Cu(bipy)2S8 ]2+ ion suggested that the complex is more likely to exist either in solution or as an amorphous compound.
