Research ArticleOpen accessIn the author namesModified Hill Cipher with Key Dependent Permutation and Circular RotationV.U.K. Sastry, V. JanakiIn this study, we have modified the Hill cipher, by including a permutation and circular rotation into the cipher. Here both the permutation and the rotation depend upon the key. From the cryptanalysis and the avalanche effect, discussed in this study, we notice that the strength of the cipher is significant. …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 6,518 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Block Cipher Using Linear CongruencesV. U.K. Sastry, V. JanakiWe have developed a block cipher by using modular arithmetic inverse and linear congruences. The cipher contains a key matrix called the outer key. It also includes another key, which contains a set of constants involved in the linear congruences. This key is called as inner key. The cryptanalysis carried out in this paper indicates that the cipher cannot be … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 7,013 accessesView PDFCite
Research ArticleOpen accessIn the author namesAntisporulant Activity of Watery Extracts of Plants against Sclerospora graminicola Causing Downy Mildew Disease of Pearl MilletS.A. Deepak, G. Oros, S. G. Sathyanarayana et al.Watery extracts of forty plant species commonly growing in across India have been screened for antisporulant activity against Sclerospora graminicola (Sacc.) Schroet., the causative agent of pearl millet downy mildew. The collection represented 38 genera of 30 families. The extracts of thirteen species did not show any effect, whereas the activity of extracts of Allium sativum, Clematis gouriana, Evolvulus alsinoides, … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 1 · 31 Mar 2007 · 7,928 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Large Block Cipher Using Modular Arithmetic Inverse of a Key Matrix and Mixing of the Key Matrix and the PlaintextV. U.K. Sastry, S. Udaya Kumar, A. Vinaya babuIn this paper, we have developed a block cipher by applying an iterative method. In the process of encryption, we have used a key matrix (K) in which all the elements are binary bits. In the process of decryption, we have utilized the modular arithmetic inverse (K-1). In the process of encryption, the elements of the plaintext and the elements … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 6,796 accessesView PDFCite
Research ArticleOpen accessIn the author namesMethylenetetrahydrofolate Reductase (MTHFR) from Mediterranean to Sub-Saharan AreasRosa Chillemi, Andrea Angius, Ivana Persico et al.There are differences in the allele frequency of MTHFR polymorphism between Western and African population. The aim of this study is to determinate the prevalence of MTHFR C677T and A1298C polymorphisms in young and old people living in different areas from Mediterranean to sub-Saharan areas. The observed vs expected genotype frequencies of 677T were in Hardy Weinberg equilibrium, with the … …OnLine Journal of Biological Sciences, Vol. 6, Issue 1 · 30 Jun 2006 · 7,590 accessesView PDFCite
Research ArticleOpen accessIn the author namesThe Effects of Transcutaneous Electrical Stimulation on the Healing of Radial Fracture in RabbitD. Sharifi, P. Yunessi, F. Sasani, S. MohitmafiThe study was performed on 10 New Zealand white rabbits 6 months old and weighing 3.0 to 4. 5 kg so as to evaluate the effects of Transcutaneous Electrical Stimulation (TES) on the right radial fracture healing. A piece of 0. 5 cm full thickness of right midshaft of radial bone was removed in all rabbits under general anesthesia. They … …American Journal of Animal and Veterinary Sciences, Vol. 1, Issue 2 · 30 Jun 2006 · 6,937 accessesView PDFCite
Research ArticleOpen accessIn the author namesManpower Consideration to Reduce Development Time for New Model in Automotive IndustryN. M.Z.N. Mohamed, H. Y. Sastra, S. M. Sapuan et al.A study of manpower consideration to reduce development time for new model in automotive industry is presented in this study. The approach taken are by studying the existing practice in car development and suggesting various ways for manpower improvement such as through early involvement and input from manufacturing personnel, the proper job scope structure, proper training to the new staffs … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,976 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn-Farm Phenotypic Characterization of Sheep Breeds in BotswanaKaelo Pelotshweu, Monosi Andries Bolowe, Nicodemus Pungi Mosweu et al.Phenotypic characterization data serve as a baseline for the evaluation of the effectiveness of selection programs and the development of conservation strategies. Therefore, this study aimed to phenotypically characterize Tswana, Dorper, Damara, Meat-master, and Karakul sheep breeds in Botswana under a ranch management system. Qualitative and quantitative data was collected from 595 adult sheep (one year and above). Data on … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 1 · 1 Mar 2025 · 7,311 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Use of Management and Hormonal Oestrous Synchronisation on Indigenous Sheep Reared ExtensivelyAyanda Maqhashu, Jabulani Nkululeko Ngcobo, Hester Adri O'Neill et al.As the global population increases, demand for animal products will result in increased livestock-related greenhouse gas emissions that contribute to climate change. One of the strategies for reducing this impact would be the improvement of indigenous livestock reproductive efficiency that are hardy and well adapted to harsh environmental regions. The use of reproductive technologies increases efficiency of animals necessary for … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 29 Aug 2024 · 4,778 accessesView PDFCite
