1,1-Difluoroethane, or DFE, is an organofluorine compound with the chemical formula C 2 H 4 F 2.This colorless gas is used as a refrigerant, where it is often listed as R-152a (refrigerant-152a) or HFC-152a (hydrofluorocarbon-152a).
The concept of 'man flu' has significant implications for healthcare, particularly in ensuring equitable access to medical treatment and dispelling misconceptions surrounding illness. Research indicates that men are less inclined to seek medical attention when unwell and may underreport symptoms when they do. [26]
It is a chlorofluorocarbon halomethane (CFC) used as a refrigerant and aerosol spray propellant. In compliance with the Montreal Protocol , its manufacture was banned in developed countries (non-article 5 countries) in 1996, and in developing countries (Article 5 countries) in 2010 out of concerns about its damaging effect on the ozone layer ...
A refrigerant is a working fluid used in cooling, heating or reverse cooling and heating of air conditioning systems and heat pumps where they undergo a repeated phase transition from a liquid to a gas and back again.
They are frequently used in air conditioning and as refrigerants; R-134a (1,1,1,2-tetrafluoroethane) is one of the most commonly used HFC refrigerants. In order to aid the recovery of the stratospheric ozone layer, HFCs were adopted to replace the more potent chlorofluorocarbons (CFCs), which were phased out from use by the Montreal Protocol ...
Sick building syndrome (SBS) is a condition in which people develop symptoms of illness or become infected with chronic disease from the building in which they work or reside. [1] In scientific literature, SBS is also known as building-related illness (BRI) , building-related symptoms (BRS) , or idiopathic environmental intolerance (IEI) .
While it may seem like a fortuitous turn of events, ethically and, in some cases, legally, financial errors made in your favor shouldn't be accepted and can, in fact, be considered theft.
When ingested, chloroform causes symptoms similar to those seen after inhalation. Serious illness has followed ingestion of 7.5 g (0.26 oz). The mean lethal oral dose in an adult is estimated at 45 g (1.6 oz). [37] The anesthetic use of chloroform has been discontinued, because it caused deaths from respiratory failure and cardiac arrhythmias.
