Arginine/Ornithine To investigate the learning curve of percutaneous nephrolithotomy under total ultrasound guidance.One hundred and twenty consecutive PCNL operations under total ultrasound guidance performed by a novice surgeon in a tertiary referral center were studied.Operations were analyzed in cohorts of 15 to determine when a plateau was rea
One hundred and seventy four accessions of sunflower were evaluated in a randomized block design with two replications during Kharif 2010-11 at Regional Agricultural Research Station, Nandyal, Andhra Pradesh to investigate the extent of genetic variability and genetic diversity.The Analysis of variance revealed significant differences among the gen
Increasing concern about the impacts of climate change on ecosystems is prompting ecologists and ecosystem managers to seek reliable projections of physical drivers of change.The use of global climate models in ecology is growing, although drawing ecologically meaningful conclusions can be problematic.The expertise required to access and interpret
The detection of non-polypoid superficial neoplastic lesions using current standard of white light endoscopy surveillance and random biopsy is associated with high miss rate.The subtle changes in mucosa caused by the flat and depressed neoplasms often go undetected and do not qualify for further investigation, e.g., biopsy and resection, thus incre
In this paper we apply transformation optics theory to thermodynamics and design thermal cloaks and concentrators with arbitrarily shaped non-conformal objects and coatings.Expressions of the required material parameters are derived analytically and then validated by numerical simulations.We apply this method to design a thermal cloak which can gui
