Oral Therapy for Experimental Coccidioidomycosis with R41 400 (Ketoconazole), a New Imidazole
The American Review of Respiratory Disease, 1978Abstract Oral treatment of mice with R41 400, ketoconazole, after intranasal challenge with arthrospores of Coccidioides immitis prevented death at doses of 40 mg per kg of body weight per day. Doses of 160 mg per kg of body weight per day during 50 to 100 days eradicated the fungus from the lungs, liver, spleen, and kidneys of ...

Abstract In this study, blend of CO2 with R41 is evaluated for application in three different systems including a refrigerated cabinet, an air-source heat pump water heater and a water-source heat pump water heater. The effects of CO2/R41 mixture as an azeotropy refrigerant on system performance are analyzed under various working conditions.

Abstract This study presents a comparative analysis of thermodynamic performance of cascade refrigeration systems (CRSs) for refrigerant couples R41/R404A and R23/R404A to discover whether R41 is a suitable substitute for R23. The discharge temperature, input power of the compressor, coefficient of performance (COP), exergy loss (X) and exergy ...

Investigation on the environmental impact of R32, R152a and R41 refrigerant blends
Engineering Research Express, 2023Abstract The improper usage of refrigerants has a drastic impact on the environment, which is contributing to global warming and ozone layer depletion. The refrigerants which are being used currently have a very high GWP (Global Warming Potential) value that signifies an adverse impact on global warming.

The performances of the transcritical Rankine cycles using R41 and CO2 as working fluids for power generation with lower temperature renewable energy are analyzed respectively and presented in this paper. The results show that the R41 cycle displays better comprehensive performance than that of the CO2 cycle.
