Multi-criteria optimization of heat recovery unit in terms of the climatic factor [PDF]

Омский научный вестник: Серия "Авиационно-ракетное и энергетическое машиностроение"
The use of heat pumps in exhaust air heat recovery systems is an effective energy-saving technology. Due to the increase in the number of refrigerants with different characteristics, a problem arises with making a decision on the use of a specific ...

Thermoeconomic Analysis of Organic Rankine Cycle From Napier Grass Biomass

Acta 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.

Fluid intake at work in foresters working in different thermal conditions

Scientific Reports, 2023
AbstractThe primary aim of this study was to assess the impact of fluid intake on hydration status indices in men at work. The secondary aim was to determine the type of fluids drunk at work in different thermal conditions. Fifty-nine male foresters were examined before and after one working day during summer, autumn, and winter. Before and after work,

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

Journal 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.

Perioperative fluid therapy in adults and children: a narrative review

Frontiers in Medicine
Intravenous fluid administration is an important part of the management of the surgical patient. Fluid can be used to compensate for the normal turnover of fluid and electrolytes (maintenance), to replace losses, to expand the extracellular fluid space ...
