What is the level of measurement for allergies?
Skin prick tests are measured in millimeters (mm). Blood test check levels of Immunoglobulin E.
What are the chances of a light skinned woman and a dark skinned man to have a light skinned baby?
its about 50/50, but mostly depending on the skin to of the grand parents
What does bleeding time reflect?
Bleeding time reflects the integrity of the vascular system and platelet function in the body. It measures how long it takes for bleeding to stop after a standardized skin puncture, indicating the efficiency of platelet adhesion, aggregation, and the function of the blood vessels. Prolonged bleeding time may suggest platelet disorders, vascular abnormalities, or the effects of certain medications. However, it is not a comprehensive test for all clotting disorders.
What happens to body when spo2 is around 52 percent?
When blood oxygen saturation (SpO2) levels drop to around 52 percent, the body experiences severe hypoxemia, which can lead to significant organ dysfunction due to inadequate oxygen supply. Symptoms may include confusion, extreme fatigue, shortness of breath, and cyanosis (bluish discoloration of the skin). Prolonged exposure to such low oxygen levels can result in critical conditions such as respiratory failure, cardiac arrest, and potentially death if not treated promptly. Immediate medical intervention is necessary to restore adequate oxygen levels.
How statistics can be misused?
There are too many ways to list, really, but here are a few common ones. First, and probably most common, is to assume that a statistical relationship equals a cause and effect one. You can, for example, quite accurately predict the damage a fire will do by counting the number of firefighters who show up to put it out. But that does not mean that firefighters cause fire damage. Other examples of this abuse can be seen everywhere in advertising. Just because kids who eat a healthy breakfast do better in school, that does not mean that the breakfast caused it or that if you suddenly start eating better your grades will improve. More likely, parents who have the sense and caring to prepare a healthy breakfast caused the kids to do better in school. Second, you can ignore other contributing variables. The classic example here is the fact that predominantly non-white neighborhoods have higher crime rates. For years, this statistic was touted as proof that non-whites are inherently violent and criminal-minded. Yet when you also consider the economics of a neighborhood, it turns out that poverty leads to higher crime, not skin color. Lastly, and this one is thankfully rare but also the most devious, you can intentionally delete cases or otherwise manipulate data to achieve the results you want. (Despite claims to the contrary, this rarely happens in legitimate science). But in general, a misuse of statistics has occurred any time that you rely too heavily on the numbers and forget that they are just numbers. If there is no practical connection between the numbers and what they represent, no common sense analysis of what the numbers mean and what could have been missed, then statistics is nothing more than just fancy math and fodder for sound bites on the evening news.
The decrease in effective conductor cross section at high frequencies?
Is called skin effect. The higher the frequency, the worse the issue.
Why is speaker wire stranded not solid?
high frequencies utilize the skin effect, running on the exterior of the conductor, with low frequencies utilizing the core of the conductor. Stranded wire has more skin area and would enhance higher frequencies, while solid wire would enhance lower frequencies. stranded is more flexible
Does rubber conduct electricity at very high frequencies?
Rubber doesn't conduct electricity well at any frequency. But to the extent that it does conduct, it's better at low frequencies than high, because of the skin effect.
What is meant by skin effect?
The skin effect occurs in conductors carrying alternating currents, where the tendency is for the current to flow towards the surface of the conductor. The effect increases with frequency. At radio frequencies, the skin effect is so pronounced, that there is little point in using solid conductors, so tubes are used instead.The skin effect is responsible for the so-called 'AC resistance'. This is because the skin effect acts to reduce the effective cross-sectional area of a conductor, thus increasing its resistance compared to when a DC current passes through the conductor.
Why does the skin effect in radio frequency caused?
Skin effect is the tendency of an alternating electric current (AC) to distribute itself within a conductor so that the current density near the surface of the conductor is greater than that at its core. That is, the electric current tends to flow at the "skin" of the conductor, at an average depth called the skin depth. The skin effect causes the effective resistance of the conductor to increase with the frequency of the current because much of the conductor does little. Skin effect is due to eddy currents set up by the AC current. At 60 Hz in copper, skin depth is about a centimetre. At high frequencies skin depth is much smaller.
Why twisted conductors instead of solid are used?
I suppose you mean cables, made out of many threads. Those are easier to bend, and thus to install. Also, it may help reduce the skin effect - this is especially relevant at high frequencies.
What is a medium frequency current?
A medium frequency current refers to an alternating current with a frequency typically between 1 kHz and 100 kHz. It is used in various electrical applications including industrial processes, medical treatments, and welding. The medium frequency range offers a balance between the skin effect of high frequencies and the power transmission efficiency of low frequencies.
What is difference between skin effect and franty effect?
skin effect that happen because the current pass at the edge of the cable in the ac current because of the frequency but in the dc the current pass throw the whole conductor the franty effect the stray capacitor increase the voltage on the line due to light load and the
Does electric current flow only on the surface of the copper conductor?
The AC current tend to flow on the surface of the conductor. The higher the frequency, the thinner the skin. This is known as the skin effect. So DC current flow throught the entire conductor but when the signal varies (AC) there is the formation of eddy current in the conductor itself and that pushes the electrons at the surface of the conductor. You can get more information on the skin effect and skin depth on wikipedia : http://en.wikipedia.org/wiki/Skin_effect http://en.wikipedia.org/wiki/Skin_depth
The cooling effect of perspiration as it evaporates from the skin is the result of high of water?
The cooling effect of perspiration is due to the high heat capacity of water. As sweat evaporates from the skin, it absorbs heat energy from the body in order to change from a liquid to a gas, resulting in a cooling effect.
What reaction occurs when rubbing alcohol is placed on the arm?
When rubbing alcohol is placed on the arm, it evaporates quickly due to its high volatility. This evaporation causes a cooling sensation on the skin due to the extraction of heat energy during the process.
What is the reason ofskin effect?
Skin effect is the behavior of electron current flow to mostly be on the surface, or "skin", of the conductor. This is due to the fact that like charges repel one another, so the electrons migrate away from each other to the skin of the conductor. This effect is particularly noticable with high voltage circuits. The impact of skin effect is that the inner parts of the conductor are not really participating in supporting the current flow, so the conductor must be made larger than expected in order to carry the current flow. In fact, many high voltage transmission conductors have a light weight non-conductive core that is used for tensile strength rather than for current carrying capacity. Skin effect is also related to the system frequency. At higher and higher frequencies, electrons tend to migrate even more to the outer surface of the conductor. In low frequency systems it is not so much a factor because it is negligible, unless high voltage such as in long distance power transmission systems in involved
