Semiconductor nanoparticles with very small size of 2-20 nm (quantum dots) are very much attractive for their excellent photoluminescence property. Therefore, this recent study portrays the green synthesis of highly...
Software testing is a valuable and time-consuming activity that aims to improve the software quality. Due to its significance, combinatorial testing focuses on fault identification by the interaction of small amount of input factors. But, deep testing is not sufficient due to time or resources availability. To select the optimal test cases with least computation time, Hybrid Multi Criteria Particle Swarm and Ranked Firefly Metaheuristic Optimization(HMCPW-RFMO) technique are introduced. Initially, the population of the test cases is randomly initialized. Then the fitness is calculated by the pairwise coverage, execution cost, fault detection capability and average execution frequency. RFM approach starts with ‘n’ fireflies. The light intensity of each firefly gets initialized.If the light intensity of one firefly is minor than the other one, it moves near the brighter one. Next, the rank is given to the firefly based on their light intensity. Lastly, the high ranked firefly is chosen as a global best solution.The result reveals that HMCPW-RFMO technique improves the software quality.
A total of 193 sera samples, along with tissues (lung, heart, and brain) collected from 136 sheep and 57 goats from the Corporation slaughter house, Madras Veterinary College teaching hospital, and private mutton shops from Chennai were tested for Toxoplasma gondii.All the sera samples were tested using modified direct agglutination test. Of the 193 sera samples, 57 (29.5 %) had a minimum titre of 1:20, with 30.14 % (41/136) of sheep and 28.07 % (16/57) of goats being seropositive. Tissue samples from all 193 animals, when subjected to B1 based PCR to detect T. gondii DNA, showed 3.67 and 3.50 % to be positive in sheep and goats, respectively. In the present investigation B1 based PCR detected T. gondii in low numbers, possibly due to limitation of the sample size. The presence of T. gondii in tissues of sheep and goats slaughtered for human consumption in Chennai indicates the role of these food animals as potential sources of infection to human.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
