Thermoeconomic Analysis of Organic Rankine Cycle From Napier Grass Biomass

open access: yesActa Technologica Agriculturae, 2023
The organic Rankine cycle (ORC) power plant is derived from a centrifugal chiller air conditioning system as an alternative to a diesel replacement modular power plant due to its low cost compared to ORC’s manufacture.

Predicting the Need for Fluid Therapy—Does Fluid Responsiveness Work? [PDF]

open access: yesJournal of Intensive Care, 2017
Fluid overdose can be harmful in critically ill patients. Since central venous pressure (CVP) is currently considered to be an inappropriate indicator of preload, much attention is being given to predicting fluid responsiveness, i.e., the response of stroke volume (SV) or cardiac output (CO) to fluid challenge.
