Why do doctors wear green masks while conducting an operation?

Green is easier on the eyes and also makes sharp contrast with blood. You can also see white or light blue clothes in some cases.





The fact that they need to wear a mask is almost obvious I think. Imagine sneezing into a patients brain or heart for example. Not fun...





As a matter of fact, surgeons are even encouraged to shave regularly, because Staphylococcus can colonize beards and contaminate surgical wounds.Why do doctors wear green masks while conducting an operation?
So they don't spread there germs.Why do doctors wear green masks while conducting an operation?
Because otherwise they would seem like a butcher...
The masks arent only green. They are just masks to keep them from getting infected, and to keep them from spitting or infecting their patient in a sterile enviroment.
To prevent anything from entering their mouth (fluid, blood, etc.) and also to prevent any illness/ bacteria from getting on the person being operated. This is because they are opening up the person and exposing the internal organs and there is no line of defense for the body at this point.
because of germs
They keep airborne germs from being inhaled.
previously it was used green, but no matter now they r using blue, white etc. as s symbolically it shows clean %26amp; green,actually masks are used to protect themselfs from infections.

How do i identify IP addresses (IPv4, IPv6) and their default subnet masks?

I do not know how well you understand computers, so all i would say is, don't worry about IPv6, it's a tech for the future and does not have any real use yet.





In case of IPv4, the default subnet depends on the class of IP address used. For instance, if you use an ideal home router setup, the IP looks something like ';192.1xx.xxx.xxx'; This is a class C address and so it's default subnet will be 255.255.255.0





If you expected something more in detail, follow up and let me know how much you already know! :)

Well, the above 2 answers are excellent! Kudos guy's! saw them after i posted this one!!





I had refrained from boggling you with the above details!How do i identify IP addresses (IPv4, IPv6) and their default subnet masks?
For what do you need to determine an IP address and using which operating system? Provide some more information to get a real answer!How do i identify IP addresses (IPv4, IPv6) and their default subnet masks?
You can check it through some sites.





examples are

Another article I did to compare IPV4 and IPV6.





Ipv4 vs. Ipv6





Ipv4 is the fourth version of Internet protocol, but the first one to be widely deployed. It uses a 32 bit addressing and allows for 4,294,967,296 unique addresses. Ipv4 has four different class types, the class types are A, B, C, and D. An example of Ipv4 is 207. 142. 131. 235. The ipv4 uses a subnet mask because of the large numbers of computers used today.





The subnet mask helps reduce the number of unique IP given to companies, corporations and so on. An example of a subnet mask is a company. A architectural company is given one ip address to use in their company. The IP that they are given is the class C addresses, 192. 182. 162. 0. However, the employees want to send information about the plan to a fellow employee. The default subnet mask is 255. 255. 255. 0 this default is used so that people can send instant messages to each other without downloading programs such as MSN messenger. The 0 in the subnet mask allows you to have 16 different networks having 14 computers per network allowing you to have a total of 224 computers in the company. You can create these networks by modifying the 0 the only number you can modify in the network. In the binary version of the 0 of the subnet mask it looks like this 0000. You can modify the numbers from 0000 鈥?1111. Those numbers will represent your network, you will then need numbers for your computer. When adding the numbers for the computer your IP would look like this in tens. 255.255.255.0-0 the zero after the dash represents your computer number. The way you can modify the number is the same as the network number, the difference is that you can only the numbers 0001-1110 in other words you cannot have all ones or all zeros. For further reference there is a diagram in the next page.





Ipv6 is the next in the advancement of IP鈥檚. Although it is version 6 it will probably be the next widely deployed Internet protocol. Compared to the Ipv4 which allows for only 4,294,967,296 unique addresses, the Ipv6 that uses a 128-bit system will hold 340-undecillion (34, 000, 000, 000, 000, 000, 000, 000, 000, 000, 000, 000, 000) this number is so vast that there are more unique ip addresses than stars in the universe, as we know it. However, the Ipv6 will not come out till at least 2025 in because they need time to fix the bugs in the protocol. An example of Ipv6 is:


207. 142. 131. 235. 207. 142. 131. 235. 207. 142. 131. 235. 207. 142. 131. 235.





The reason we may need to switch from Ipv4 to Ipv6 is because of the population of the world. The rate at which the world鈥檚 population is growing is nothing to look down at. Also in the future all vehicles will probably be networked in order to use Onstar or other navigational devices and those need IP鈥檚 too. So eventually we would need more unique IP鈥檚 than the number we have now.
Try to identify information's about your IP address and PC on:





http://www.ipaddresslocation.org


http://www.find-ip-address.org
To do this, we need to convert the first octet to binary, and look for the position of the first zero.





Class A: 0xxx xxxx 0-127


Class B: 10xx xxxx 128-191


Class C: 110x xxxx 192-223


Class D: 1110 xxxx 224-239 - Multicast


Class E: 1111 xxxx 240-255 - reserved





The word normally used instead of default is natural mask,

Eggs:D


They help tone and make your skin firmer and softer.


Michelle Phan has a video on it.


You separate the egg white and egg yolk, beat the egg white till it is nice and foamy/frothy, and apply on skin, then it will be ready once you can't smile(try to smile and if you can't it's done) rinse off with warm water, then this step is optional but take a tiny bit of the egg yolk and apply to skin, it is a natural moisturizer, then do the smile test again, rinse off, pat face dry with a towel and apply your moisturizer(not egg yolk).


And you are done!

Do clay based face masks work?

I use clay based face masks once a week and well are they actually any good??





when is the best time to use then, morning or night??





Do clay based face masks work?
yes i believe that they are very good. I personally use them at night and afterwards use a natural organic facial exfoliator with very little mico beads. they work although i use them once a month.. hope this helps





=]Do clay based face masks work?
It depends on your skin type and what you are hoping the mask to achieve.





Generally mud-based masks tend to try out your skin, so they're good if you have quite greasy skin and/or are prone to spots as they suck out the impurities.





I have very dry skin and so the mud masks tend to just make my skin feel uncomfortably dry and flaky.





The most important thing to remember is to remove all of the mask - if you leave a trace of it, it may continue to dry out your skin - and then apply a good moisturiser afterwards.





Also, I would advise exfoliating before you apply the clay mask so the mask can act more deeply.
i have no idea,





BUT clay is fun if you like making pots (wouldn't recommend eating it, seriously)





i would make a pot in the afternoon, that way i am awake

Flight attendants indicate that bags attached to the emergency oxigen masks may or may not inflate. Why?

They tell you that so that if you need them you won't panic when the bags don't inflate.Flight attendants indicate that bags attached to the emergency oxigen masks may or may not inflate. Why?
A classic corporate CYA.

  • Has Sleep Apnea but is terrified of oxygen and gas masks!!!?

    My friend has really bad sleep apnea, and she wants to do something about it, but she is absolutely terrified of oxygen masks, or anything of that sort. what can she do?Has Sleep Apnea but is terrified of oxygen and gas masks!!!?
    There are some that are very small - just tubes up the nose. Frankly, I think these would be more uncomfortable than the full nose mask ones, but if she has a phobia about something covering her face, maybe this would be better for her.





    Apnea is really hard on your heart. Left untreated, it can take like 20-30 years off of her life. Maybe these facts will influence her to make an effort to overcome her fears?Has Sleep Apnea but is terrified of oxygen and gas masks!!!?
    I am clausterphobic and have sleep apnea. I spent a lot of time with the RRT. I sat up and watched TV with the mask close to my face at a low setting. We worked really slow. I have tried all kinds of masks. Some people like the nasal programs. They also make an oral mask. They make dental devices that work for some people.

    Best wishes.
    Ask the Respiratory Therapist who set it up for her. I'm sure he/she's dealt with that problem before. Just call the company who delivered it and ask for the RT to come by and teach you how to use it.Most of the companies have RT's on the staff just for that purpose. He/she can show you what your options are.
