    Homology modeling involves taking a known sequence with an unknown structure and mapping it against a known structure of one or several similar (homologous) proteins. It would be expected that two proteins of similar origin and function would have reasonable structural similarity. Therefore it is possible to use the known structure as a template for modeling the structure of the unknown structure. Proteins that share the same function generally have similar structures. During alignment if two proteins show maximum sequence identity they also show a similar folding pattern. This principal has became the foundation of homology modeling. 
The Geminivirus taxonomic group of plant viruses is characterized by geminate particles and genomes consisting of single-stranded circular DNA molecules of about 2.5 to 2.8 kb in size. Agricultural plants are threatened by many diseases caused by whitefly-transmitted geminiviruses. Since these diseases are in a fast spreading phase, it is urgent to devise rapid diagnosis methods and to produce resistant plants.

    Layout Optimization of a repair facility using discrete event simulation

    Technological advancements in the field of simulation have enabled production managers to model and simulate their facilities under various scenarios, in order to optimize system performance. In particular the reconfiguration of factory layouts can be time consuming and expensive; Discrete Event Simulation (DES) can be used to model and assess various scenarios to assist production managers with layout planning. Significant benefits can be achieved through the use of DES for factory layout optimization including: decreased lead times, reduced manufacturing costs, efficient materials handling and increased profit. This paper presents the development of a DES model in WITNESS for the analysis and factory layout optimization of a repair facility. The aim of the model is to allow decision makers to assess various layouts and configurations with a view to optimize production. The model has been built with a link to an Excel spreadsheet to enable data input and the visualization of Key Performance Indicators (KPIs). Specific functions have been built into the simulation model to set and save new layouts within Excel to facilitate layout optimization. The model will be used to optimize the factory configuration

    We retrieved six protein sequences of Tomato leaf curl Joydebpur virus (ToLCJV) DNA-A [FJ345402] from GenBank-NCBI (ACJ03821, ACJ03822, ACJ03823, ACJ03824, ACJ03825 and ACJ03826) which were used for computational modeling structure prediction. Ramachandran plot of ACJ03826-AC4 had maximum 73.3% and ACJ03822-AV1 had 71% residues in core region therefore these models cannot be placed in a good quality category. ACJ03824-AC2 had only 18.6% residues in core and 13.6% residues in disallowed regions and therefore it was the least stable protein. Verify-3D graph profile scores for selected ToLCJV proteins were greater than zero. Therefore all the verify-3D graph corresponds to an acceptable environment for the model. Findings of the present study provide a base for docking and In-Silico anti-Begomoviral compound designing

    Let uϵC2(Ω‾)u\epsilon C^{2}\left(\overline{\Omega}\right)be a positive solution of the differential equation Δu+f(u)=0\Delta u+f\left(u\right)=0 in Ω\Omega with boundary condition u=0 on ∂Ω\partial\Omega where f is a C1^{1} function and Ω\Omega is a geodesic ball in the hyperbolic space Hn\mathbf{H}^{\mathbf{n}} (respectively sphere Sn)\left(\textrm{respectively}\:\textrm{sphere}\:\mathbf{S^{\mathbf{n}}}\right). Further in case of sphere we assume that Ω‾\overline{\Omega} is contained in a hemisphere. Then we prove that u is radially symmetric
