What is the use of water vapour?
i believe the use of water vapor is (to help us breathe), rain and clouds to block the sun for shade where there are not many trees. also, it creates fog so some people can paint it. my main reson is the cloud one. when water vapour gathers together, it creates clouds. when it is hot, people playing tennis, footy, ect. want shade and there aren't any trees or shelters, they can rest in the shade that the cloud created.
How does Daylight Saving Time save energy?
Having more hours of daylight is supposed to reduce the number of hours lights are turned on each evening, but that saves no energy. It only wastes energy because Daylight Saving Time does not bring more daylight. People have to wake up to a darker sky and fiddle with electricity if they cannot see.actually daylight saving time was started during a war so there could be more light to battle in -UBERnoob1098 +++++ You are right in that it brings no more daylight. The "a war" was actually World War Two. Britain introduced what in fact we now call British Summer Time to help farmers particularly by making better use of the available daylight, but the belief grew that it made it harder for the Luftwaffe to bomb British cities. It didn't of course because the numbers of hours of light and dark do not change, only our clock reference with respect to longitude-determined solar noon. The bombers needed only to re-schedule their raids. Similarly with land and sea action - the effect of day or night on fighting was down to lengths of either, NOT to clock time. ' Its only practical use is in moving the working day so we can use the evenings more effectively, but it comes with a cost especially the further North you live. Each time the clock is moved forwards or backwards, our bodies' internal natural clocks are temporarily put out of sync with the daylight they need for normal calibration, and the clock changes are marked by a short spike in traffic and other accidents, and in heart attacks and strokes. Effectively we all suffer from something akin to "jet lag". Night-shift workers are similarly but more seriously affected. ' A peculiar myth common in Britain is that each change from GMT to BST or back gains or loses an hour in bed. It doesn't really, unless perhaps you change the clocks before going to bed, then set the alarm. If you let your body decide correctly, it will sleep and wake nocturnally and as and when physiology decides, but most of us now live to very artificial day/night arhythms that taken to sleep-deprivation extremes (common particularly among young people fixated on the Internet) are bad for us! The change is always set officially at 2am on a Sunday morning to cause the least disruption, but it's up to individuals to decide when they change their own time-pieces.
What are pre ductal saturations?
Pre-ductal saturations in a newborn are measured in the right hand and is a measurement of the arterial blood oxygen saturation after the blood leaves the heart and before it reaches the ductus arteriosus in the aorta. This is the blood that is perfusing the brain.
What does arterial mean as in arterial o2 saturations?
Arterial is a reference to the blood in the arteries, as opposed to blood in the veins.
What term describes the level of air saturations?
relative humidity Humidity is the term that describes the level of air saturation.
How do you monitor preductal saturations in a neonate?
With a pulse oximeter on the upper right extremity (i.e. right wrist/hand)
What is the dying result of Mixing polyester yarn with cotton yarn?
The yarns will absorb the dye at different rates and in different saturations, but you will have the same hue in the mix, so you can work them together. This assumes that you're starting with colourless yarns.
Why cerebral oximeter normal value is much less than pulse oximeter?
cerebral oxygen saturation are weighted venous samples (70% venous, 30% arterial) Pulse oximeter values are based on arterial oxygen saturations.
How long can humans survive with low oxygen saturation?
Depends on how low you are talking. Yes some people can survive with relatively low oxygen saturations, by compensating in other ways (ie increase the number of red blood cells).
What is a good oxygen blood level?
In terms of oxygen saturations, arterial blood should be around 97-100% and venous return should be at approximately 75%. These figures are only appropriate for altitudes close to sea level.
How do you stop yawing i have a big show coming up and i just cant stop yawing please help me im in a hurry?
Yawing is the bodies reaction to lower oxygen saturations in the blood and/or increasing carbon dioxide saturations. It occurs when a person is tired as their body is having to work harder, producing more CO2 or not as effectively gaining O2. Getting sleep is an obvious treatment. Other wise, cardiovascular activity will help as it helps to open the airways, and promote gas exchange. It also produces endorphins which can help to feel re-invigorated, and may override the yawn stimulus for a certain time.
What are all the colors of topaz?
Topaz actually has an exceptionally wide color range that, besides brown, includes various tones and saturations of blue, green, yellow, orange, red, pink, and purple. Colorless topaz is plentiful, and is often treated to give it a blue color.
What is normal saturation?
"Oxygen saturation" refers to the fraction of hemoglobin that is saturated by oxygen. It is related to the partial pressure of oxygen in the inspired air and, therefore, to altitude. Normal oxygen saturation in an otherwise healthy individual at sea level is > 95%. Low oxygen saturations can be found in a wide variety of lung diseases.
How much steam to make 1 ton of condensate?
1 ton of steam. how much steam is vague question. steam can be at different pressures and saturations. At 212°F, 14.7 psia, liquid water has a specific volume of 0.016716 ft3/lbm and steam has a specfic volume of 26.80 3/lbm, which is a volume ratio of ~1603 : 1 of steam:water.
