Evolutionary Synthesis of HVAC System Configurations: Algorithm Development. [PDF]

open access: yes, 2008
This paper describes the development of an optimization procedure for the synthesis of novel heating, ventilating, and air-conditioning (HVAC) system configurations. Novel HVAC system designs can be synthesized using model-based optimization methods. The

Impact of leaks and ventilation parameters on the efficacy of humidifiers during home ventilation for tracheostomized patients: a bench study

open access: yesBMC Pulmonary Medicine, 2019
Background During invasive ventilation, the upper airway is bypassed and no longer participates in humidification of inspired gases, which is essential to avoid harmful consequences such as endotracheal tube occlusion.

Assessing Inhalation Exposures Associated with Contamination Events in Water Distribution Systems. [PDF]

open access: yesPLoS ONE, 2016
When a water distribution system (WDS) is contaminated, short-term inhalation exposures to airborne contaminants could occur as the result of domestic water use. The most important domestic sources of such exposures are likely to be showering and the use

Perceived dryness in houses and adverse health effects during winter in Japan [PDF]

open access: yesE3S Web of Conferences, 2023
In recent years, as houses have become more insulated and airtight, indoor environments in Japan have tended to become low-humidity in winter, making dryness a problem. The relationship between the perception of dryness indoors and low indoor humidity is

Analysis of Surrogate Models for Vapour Transport and Distribution in a Hollow Fibre Membrane Humidifier

open access: yesEnergies, 2023
To achieve high efficiency and low degradation of a polymer electrolyte fuel cell (PEMFC), it is necessary to maintain an appropriate level of humidification in the fuel cell membrane.

Severe neonatal legionellosis associated with use of home humidifiers – A case report

open access: yesClinical Infection in Practice, 2020
Neonatal Legionella pneumophila infection is rare and mortality is high. There has been limited success with the use of extracorporeal membrane oxygenation, with reported mortality in infants of 88%.

The Microbial Colonization Profile of Respiratory Devices and the Significance of the Role of Disinfection: A Blinded Study [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2013
Introduction: Approximately 10-40% of all the nosocomial infections are pulmonary, which lead to grave complications. Elderly, debilitated, or critically ill patients are at a high risk.

Demographic differences in use of household tap water in a representative sample of US adults, FallStyles 2019

open access: yesJournal of Water and Health, 2021
Tap water that is safe to consume may cause respiratory illness (e.g., Legionnaires’ disease) when water conditions allow for proliferation and aerosolization of biofilm-associated pathogens.
