TL;DR: In this article, the authors studied an enhancement of heat transfer in an unsteady rotating flow for the aqueous suspensions of single wall nanotubes under nonlinear thermal radiation.
Abstract: The main objective of the present analysis is to study an enhancement of heat transfer in an unsteady rotating flow for the aqueous suspensions of single wall nanotubes under nonlinear thermal radiation. Appropriate transformations are implemented for the conversion of partial differential systems into a set of ordinary differential equations. The transformed expressions have been scrutinized through RKF-45 order method along with shooting technique. The impact of various pertinent parameters for the velocity and temperature fields are analyzed through graphs in detail. Also, the role of substantial parameters on the fiction factor and mass transportation rates is determined and conferred in depth through graphs. Our simulations established that the higher value of rotation rate parameter reduces the thickness of the momentum boundary layer thickness. Further, an unsteadiness parameter increases velocity and temperature profile decreases.

TL;DR: In this article, the activity concentration of natural primordial radionuclides, namely 226Ra, 232Th, and 40K in different rock samples of Ramanagara and Tumkur districts, and has been studied by using gamma ray spectrometry.
Abstract: The present study deals with the activity concentration of natural primordial radionuclides, namely 226Ra, 232Th, and 40K in different rock samples of Ramanagara and Tumkur districts, and has been studied by using gamma ray spectrometry. The average activity concentration of 226Ra, 232Th, and 40K in the collected rock samples was found to be 41.08 ± 2.12, 86.26 ± 2.94, and 869.29 ± 3.78 Bq.kg−1, respectively. The average radium equivalent activity (Raeq) was found as 225.29 Bq.kg−1 and these values are well within the recommended limit prescribed for dwellings as 370 Bq.kg−1. The external (H ex) and internal hazard index (H in) values are also less than unity. The mean value of absorbed dose rate in rock samples was found as 107.33 nGy.h−1, respectively, and is slightly higher than the worldwide average value. The average indoor and outdoor annual effective dose values for rock samples are 0.526 mSv.y−1 and 0.131 mSv.y−1, respectively. These values are lower than the average world recommended value of 1 mSv.y−1.

TL;DR: The potent antioxidant and its correlative hepatoprotective activity of the methanolic extract and isolated constituent dehydroabietylamine is attributed to its antioxidant and free radical scavenging activities.
Abstract: Background: The present investigation evaluates the hepatoprotective and in vitro antioxidant effect of methanolic extract and its isolated constituent, dehydroabietylamine, in Carthamus tinctorious L, var Annigeri-2-, an oil yielding crop. Materials and Methods: The hepatoprotective effects were estimated for the parameters viz, total bilirubin, total protein, serum alanine amino transaminase (ALT) and serum aspartate aminotransferase (AST) and alkaline phosphatase (ALP) and along with the pathological findings of hepatotoxicity. The in vitro antioxidant activity was evaluated by using free radical scavenging assays: DPPH, nitric oxide radical scavenging, hydroxyl radical, reducing power, ferrous ion chelating ability and total antioxidant capacity. Results: Both the methanolic extract (at 150 and 300 mg/kg bw) and dehydroabietylamine (at 50 mg/kg bw) showed significant liver protection against CCl 4 -induced liver damage that was comparable with the standard drug, silymarin (100 mg/kg bw), in reducing the elevated serum enzyme markers. The liver sections of the animals treated with dehydroabietylamine elicit a significant liver protection compared with the methanolic extract against CCl 4 -induced liver damage. Further, both the methanolic extract and dehydroabietylamine exhibited a considerable and dose-dependent scavenging activity of DPPH, nitric oxide and hydroxyl radical. Similarly, in the reducing power assay, the results were very persuasive. In addition, the Fe 2+ chelating activity and the total antioxidant assay established the antioxidant property of the methanolic extract and its isolated constituent. Among the two experimental samples, dehydroabietylamine proved to be more effective for the said parameters. Conclusion: The potent antioxidant and its correlative hepatoprotective activity of the methanolic extract and isolated constituent dehydroabietylamine is therefore attributed to its antioxidant and free radical scavenging activities.
