In it a alphanumeric key of 32 character is used with transposition and substitutions. These mutate the plain text by many ways before cipher text takes the shape. The encryption, decryption, key generation is explained with suitable example. The cipher is very strong as it is indicated by examining the cryptanalysis.

Enhanced hepatic differentiation of mesenchymal stem cells after pretreatment with injured liver tissue

Differentiation, 2011

Liver failure represents a serious challenge for cell based therapies. Mesenchymal stem cells (MS... more Liver failure represents a serious challenge for cell based therapies. Mesenchymal stem cells (MSCs) possess potential for regeneration of fibrotic liver; however, there is a dire need to improve their hepatic differentiation. This study examines a pretreatment strategy to augment the differentiation potential of MSCs towards hepatic lineage. MSCs were isolated from C57BL/6 wild type mice and were characterized by flow cytometry for CD44 (92.4%), CD90 (96.6%), CD105 (94.7%), CD45 (0.8%) and CD34 (1.4%) markers. To improve the differentiation potential of MSCs towards hepatic lineage, cells were pretreated with injured liver tissue in an in-vitro model, which resulted in high expression of albumin, cytokeratin 8, 18, TAT and HNF1α as compared to untreated MSCs. The efficacy of pretreated MSCs was evaluated by preparing in-vivo mouse model with liver fibrosis by intraperitoneal administration of CCl4. Pretreated MSCs were transplanted in the left lateral lobe of mice with liver fibros...

Quantitative Estimation of Cost Drivers for Intermediate COCOMO towards Traditional and Cloud Based Software Development

Proceedings of the 9th Annual ACM India Conference, 2016

Cost estimation models are used for calculating the associated amount required for developing the stakeholder's requirement within the defined time boundaries. Among several models available for the cost estimation of software projects, COCOMO is one of the well-known models which serve the field most. Resources applied for the given time will generate the rough estimates, but for more accurate values, various factors are analyzed. These factors are termed as cost drivers. Software estimation using COCOMO is performed by selecting values of cost drivers on a predefined scale. This approach solely depends on experience of a software analyst. However, there is a lack of a systematic approach available for the selection of values of these cost drivers. Our work suggests the quantification of cost drivers for intermediate COCOMO. Quantification will i...
