AIR


air

(ār),
1. A mixture of odorless gases found in the atmosphere in the following approximate percentages by volume after water vapor has been removed: oxygen, 20.95; nitrogen, 78.08; argon 0.93; carbon dioxide, 0.03; other gases, 0.01. Formerly used to mean any respiratory gas, regardless of its composition.
2. Synonym(s): ventilate

AIR

Aerosolised Iloprost Randomised Study. A trial comparing functional changes caused by iloprost, a stable prostacyclin analogue, to placebo in patients with pulmonary hypertension.
Primary endpoint 10% increase in 6-minute walking distance and an improvement in the NYHA functional class.
Conclusion Iloprost was better than placebo. Combined clinical endpoint was met by 17% vs. 5% in the placebo group, distance walked in 6 minutes was 36 meters greater, functional class improved, dyspnoea decreased, quality of life increased, and fewer treated patients died or deteriorated. Syncope was similar in both groups.
Adverse events Tolerable flushing and jaw pain.

AIR

Abbreviation for 5-aminoimidazole ribose 5-phosphate; 5-aminoimidazole ribotide.

air

The mixture of gases forming the atmosphere of the earth. It consists of about 78% nitrogen, 21% oxygen, 0.1% argon, 0.03% carbon dioxide and smaller proportions of rare gases and ozone. A continuing adequate supply of oxygen is essential to life.

Patient discussion about air

Q. Are superbugs contagious through the air? Last week we visited my dad in the hospital, and we noticed that on the next room’s door there was a warning sign. After asking, we were told it was a denoting that the patient inside had a superbug (called klebsiella). On our way out we passed against this patient in the hallway – is it possible that I also carry this superbag? Is it dangerous?

A. Usually these bacteria are transmitted from person to person through direct contact, and less through the air. Moreover, these germs are dangerous in ill and debilitated patients, and not in normal healthy individuals.

Q. breating air that has tetrachloroethene in it how does it affect you if u have prostate cancer the air in my building has been determined to have Tetrachloroethylene in it i have just been diagnosed with prostate cancer

A. i found a research they did in Finland about tetrachloroethene, and they saw that amongst the people who were exposed to it over the years there was an increased amount of cancerous events. and even prostate cancer.

Q. where would i find list of all the "clean" cities and the rates of air pollution ...?

A. i don't know about a list of "good" cities, but i know a list of the worse cities for Asthmatic people!-

The capacity table has five inputs: unit combination ratio (number of active indoor units/number of active indoor units at rating conditions), outdoor air dry bulb temperature, indoor terminal unit air flow rate, terminal unit inlet dry bulb temperature and relative humidity and three outputs: terminal unit total capacity, sensible capacity and fan power consumption.
In trailing vehicle, significant thermal performance drop was observed in both single-lane and two-lane traffic conditions due to lower cold mass air flow rates. A significant temperature raise was observed in the constant heat rejection rate model when compared to the varied heat rejection rate model.

The cooling capacity needed by the HVAC system is dependent on the air flow rate and the temperature difference between the inlet and a discrete area weighted sum of the temperature at the outlet.
The high percentages for Zones A and B are a result of the low supply air flow rates that these zones receive; the actual interzonal flow rates are not particularly high.
The combination of the experimental results and numerical modeling showed that the most important parameters controlling the speed of the epoxy and coating thickness were the air flow rate and temperature, since they determine the shear forces on the epoxy layer and the rate at which the epoxy cures.
The water feed to the atomizer is a function of air flow rate which was controlled using a control valve.
