- Say if someone that has hep B and they cut them selves and the blood dries up how long will it take for the virus to die? I am just curious. Thanks for answering.
Answer by Bobo
The hepatitis B virus, or HBV, can still be infectious for up to a week outside the body. The hepatitis A virus, or HAV, is relatively hardy. In good conditions, it can survive outside the body for months. HAV can survive certain acids and some heat. For a period of time and under certain conditions, HAV can survive in sea water, dried feces and live oysters. The hepatitis C virus, or HCV, can live outside the body for up to 4 days. However, many experts think it usually survives up to 16 hours at room temperature. The HIV virus can only live outside of the human body for a few minutes, even in the best conditions.
- Suppose a ≥ 0 and b ≥ > 0 are rational. Show that √a + √b is rational if, and only if, √a and √b are rational. And that √a - √b is rational if, and only if, so are √a and √b.
Answer by Lake R
One direction is rather trivial. If √a = p/q and √b = r/s with p, q, r, s integers, then √a + √b = (sp + rq)/(sq) which is clearly rational. Now, suppose that a = i/j and b = k/l and suppose further that √a + √b = c/d. Then note that a = (√a + √b - √b)² ==> i/j = (c/d)² - 2(c/d)√(k/l) + k/l. If a = b = 0, then we are done. Otherwise, c/d ≠ 0 and we can write √b = √(k/l) = [k/l + c²/d² - i/j]/(2c/d) which is rational. A similar argument shows that √a is rational. The argument for √a - √b is similar. However, you have to add the hypothesis a ≠ b. Otherwise, you can come up with an obvious counter example such as a = b = 1/2. The √a and √b are not rational whereas √a - √b = 0 which is rational.
- A is a simple point support pushing up, and 8 feet away from that is point B, also a support pushing up. These points are parallel and support a twelve foot beam that starts at point A The beam is cantilevered four feet to the left of point be and at that four foot point is 1000 pounds pushing down. How do I find the moment around points A and B?
Answer by jmcp7227
im confused somewhat. is the 1000# directly over point B or 4' to the right of it.
Home insurance is something that every single home owner should have. I am not exaggerating when I say this. Disaster can strike at any minute, and with the growing unrest in the americas it is about time for everyone to open there eyes and realize that their house is in more danger than it has ever been. I mean not only do we have civil threats on our properties, but we still have the looming natural disasters over our head. Each and every year there are a seemingly greater amount of natural disasters sweeping across our nation and those that are not insured are paying a hefty fine, they are not getting the coverage they need so god forbid, when there house is destroyed there is noone to pay for it. If it is under a loan, you now owe money on a house that you don't even have. So be smart and get yourself some insurance, because even if it is not likely that something happen to your home, you do not want to be the person that loses everything because you were not proactive enough to do anything about it. So go ahead and get yourself some insurance. If it is only useful once in your life it has already paid for itself ten times over. Replacing a home is expensive and you should never have to do it if it can be avoided. Home insurance is not even really that much, sure it is not super cheap, but it is not really that much. If you need to have your home appraised so you can know what you should be paying for insurance, you should go ahead and do that. It is important to always know the value of your house anyways so I suggest that to anyone and everyone.Take A Peek
There are many ways to find internet providers in your area, the simplest of which is to go to that one place that we used to look at on a daily basis, that place is the phone book, the phone book will have an accurate depiction of who is selling internet in your area. The internet can give you a general idea, but it is nowhere near as accurate as the phone book,t he phone book pretty much tells you any business that has a phone number in your area, and if they have a phone number, that means they service at least part of your area, and that is all you really need to know to get the ball rolling in the right direction, once you have narrowed down your options to a few potentials, you can go in and talk to them to try to hash out a deal, or you can just call them. There is even a third option now, you can even start or extend a plan online, without ever interacting with another person. This option is my personal favorite, as it allows me to get a great deal without having to suffer through being transferred time and again. Even better than that is the fact that the internet often times has way better deals than they would otherwise offer you. You can get all sorts of great deals online, and it's all very simple. You just have to go to the various sites and check and see who is offering what deal at the moment, usually they offer good deals only for a yeal, then after that the rates go up, but if that is the case just cancel after a year and switch toa new, better offer at that time. It is a very simple process.Take A Peek
My passion has always been cars, but the thing I really love about cars is taking them apart and putting them back together. At a young age, my father let me watch while he worked on the family car and he even let me help in some instances. From this, I developed an interest in how cars work and how to fix them. I want to share my love of cars with other by opening up my own auto repair shop. Before opening a shop, I need motor trade insurance, and I've been looking at different rates on http://motortradeinsurance.tripod.co.uk.
Motor trade insurance is necessary for anyone who owns a repair shop, because it covers a shop owner in the event that something happens to a vehicle while they have it. I've gone through many years of professional training and automotive courses and have become very skilled in auto maintenance, but there is always a chance that while I or someone else in my shop is working on a car, it may have problems, thus the insurance kicks in.
Finding motor trade insurance is very similar to a driver looking for car insurance. There are a lot of companies that offer competitive insurance rates for those in the motor trade industry, which doesn't only include repair shop owners. Some companies will over more coverage than others, and some will offer better prices than others. The best way to know which insurer to choose is to look carefully at each one. There is a good chance that someone has used a particular insurance company before, so if you look for reviews of their insurance policies and performance, them you'll be able to gain an idea of whether the company is good or not. The best companies will have more good reviews than bad ones.Take A Peek
Cheap dsl is a very hard thing to find these days, which is fairly strange considering that the price of internet has consistently been dropping over the years, but this thing alone has remained constant. Every once in awhile a new company will emerge and try to flip the world upside down by offering cheaper prices, but that generally comes to a cost to themselves. They almost always go out of business within the first year because it is literally at it's breaking point as it stands. Dsl companies barely profit, so they can not really lower the price or compete against eachother at all. So to find something that you would consider cheaper than the other is pretty much impossible, but do not give up on dsl, because it is all actually fairly cheap. I mean compared to normal internet, it is a little bit on the slow side. But it is entirely worth it, because the price is just that much better. If you do not plan on gaming on your computer than you really don't need blazing fast speeds anyways. You can live just fine with one mega byte per second if you just use the internet for email and perhaps even facebook. Aside from gaming you can do whatever you want with dsl, and you can even do some light gaming. Just remember that there is nothing that you really need thirty mega bytes per second for, so don't let them try to talk you into increasing your service. But if you want to game, you are going to need to pay up for at least fifteen mega bytes per second, which is still fairly cheap and you can also get that internet for fairly cheap. The decision is yours, just do not be afraid to shop around a bit.Take A Peek
I was going to Europe with my daughter and I did not want to carry a lot of cash on me because I was afraid that since it was just the two of us girls looking at the different sites together. I did not want to carry more than I had to, I was afraid that I would lose it. I have been known to lose a few things in my life time, especially my keys. I went online and looked at taxi moto a paris and found that there was a way for me to pay for the taxis with a credit card. I called my credit card company and told them that I was going to be out of the country for a few weeks and that I wanted them to know about this. They told me that it was a good thing that I called to tell them that I was going to be out of the country because they told me that they were possibly going to go and decline me, as they might see that as a flag.
I was told by my dad, who travels a lot, to call the credit card company every single time you even go out of the state to tell them that you are going away and that you are going to be in either certain states or certain countries. The best thing about the call was that the credit card company told me that I could go online and even do this from their web site. I was so happy that I could do this and it would save me a lot of time. I could do this when I was on the plane if I forgot at the last minute, it was a really great and perfect thing.Take A Peek
My wife has me helping her set up her new business all day. It is sort of a little day spa, but not so elaborate as a lot of those places. In actual fact she says that she is not going to let men in the place if she can work out how to do that legally. I told her that was fine with me and I would leave her massage tables and that other stuff out in the parking lot for her. Of course that was not going to work in my wildest dreams and I spent all day moving stuff in and then moving it around until she was happy about how it all fit together. Take A Peek
I am not sure how long I am going to be able to hold out, because I thought for sure that I would break down and pay for cable or satellite TV after football season started. Of course I live in the city and across the street from my apartment there is a place where they have a laundry mat that is also a bar and a restaurant of sorts. I know the guy who owns the place and every once in a while I will help him out. He helped me get a free netflix account in fact and I use it on this little thing you call a Roku or something like that. It is okay for that sort of thing, especially since you can use it on your TV and not have to worry too much about anything else. Of course I am on the Internet while I watch TV, so I do not really focus too much on much that is on my TV.
I was trying to set it up like this friend of mine. He has a different type of media player that he can hook up to his computer network. I can not figure out what I need to do to get this set up right to be honest. He does it so that the music and video on his computer hard drives can be played on both his stereo and on his big screen HD television. It looks and sounds great and I am a bit jealous of him and the set up that he has. I know that there is a way to do that with this box, but it seems to be pretty clunky and I can not quite figure out exactly how to make it work the way that it should.Take A Peek
With the internet we do not need to buy the encyclopedias that our parents grew up with. Buying a new set of encyclopedias every few years was important because the information inside of them may not have been as up to date as the time of the research. I was looking online and I found that there is wiki, while it may not be as fancy as a book, it has a lot of great information with people that the facts to make sure it is up to date. I looked up garcinia cambogia wiki and found that there was an entire page that was dedicated to the ingredient found in food. I found that there were a lot of links that were connected where I could click to go to another page if I was not familiar with a term or word that they were using. This is a great asset so people do not have to be confused if they do not have a clue as to what they are reading.
My family and friends also told me that they like to use wiki to look up information and they will even tell their kids to use the site if they do not know the answer to something. I found my parents old volumes of encyclopedias and I could not believe how out dated the information in them was. It was fun to see how they still listed East and West Germany as separate countries instead of one unified Germany. My daughter did not even know that there was a wall in between the two countries that separated them. Many people that live there that are older are still stuck in the mindset that they are living in two different countries with different political ideologies and its very interesting.Take A Peek
Mary Anne and I just got home after a long trip to Blowing Rock, up in North Carolina. I was able to rent us a nice place up there for a couple of weeks and we spent some time hiking and going around to all of the tourist type places up there. We had thought about going to Dollywood, but it is not really our sort of thing to be honest. I am grateful that I did not have the cheapest car insurance that I could have, because we did run into a bit of a problem while we were up there near the state line. It was one of those things that some times happens up there. We just came around a bend in Interstate 40 and we ran into a parking lot. There had been a small rock slide up ahead and it had blocked one of the lanes. Of course if you were careful you could drive around it, but some of the people were afraid to drive through it all, perhaps fearful of more rocks coming down.
We stopped in time, but this left us in a pretty exposed position obviously. These people are driving 75 and 80 mph, while hardly expecting that you are sitting there at a dead stop just around a corner. The accident began just moments after we stopped and in the end we were pretty much the luckier ones. A lot of cars got hit harder than we did and it does not make much sense. We got tapped forward into another car and that thing seemed to be made out of glass to be honest. The big thing was what do you do next. I was not about to get out of my car and stand there waiting for the next car to smash into us.Take A Peek
Finding a reliable, trust worthy doctor is not an easy task these days. It is hard to enough to find friends that we can trust but to find someone who is going to help advice you on your health is a completely different matter that we have to worry ourselves over. Before I see a doctor, I spend some time on Google researching them by checking out some of the reviews that you can find on the web or even trying to find a blog by them, such as the blog of dr alex simring, who was going to be the next doctor that I went to visit after a recommendation from a friend. I hadn't been feeling so well thanks to a drastic change in diet (due to diabetes), which apparently is something Dr. Simring is very familiar with (nutrition, not diabetes). Being forced to change my diet because of diabetes has been one of the hardest things that I've ever had to do.
Diabetes, apparently, runs in the family; I wish I had known beforehand so I could have watched my diet more carefully! Now I definitely have to watched my diet much more carefully since going outside the recommended foods that I should be eating could certainly kill me. I can't even drink beer safely anymore without fear of having some sort of diabetic attack - not to mention the crazy mood swings that accompany it. That's how we discovered it in the first place. I was having incredible episodes of anger that filled me with intense rage. After one particular potent episode, I began to vomit and shake; which resulted to a trip to the hospital! A year later I am still trying to adjust to diabetes. My whole life has been completely altered around this disease.
One of the things that I really enjoy about being able to spend time with my wife, is that we have similar taste. Neither of us are really wrapped up in complicated things. We want our life to be simple. We like to be able to sit back and do things like watch movies online. In fact, for us watching movies has been a major part of our life.
I clearly remember our very first anniversary. We were ,like most couples our age very poor. We barely had enough money to do nice things. So what we decided to do is take the money that we had, and go to the theater and watch multiple movies. Thankfully, our anniversary fell on a day where the movie theater was giving movies at a 2-for-1 price. So, we watched three movies and only paid in the equivalent of 1 ½ movie tickets fare. It was a great day. After that, we went out to eat at an inexpensive restaurant.
Over the years we have become more financially stable. We are not rich by any means. However we have had enough money to be able to do some more complicated things for our wedding anniversary. However, every single year we have continued with our tradition. Every single year for the past decade on our wedding anniversary we have gone to watch at least one movie.
My wife and I decided that we did not need cable television. The reason why we made this decision is because with the wide range of movies available online, anything that we want to watch we can watch for free online. I think that sooner or later more and more people are going to choose to get rid of cable and instead just use the Internet for all of their entertainment needs.Take A Peek
So every day I get asked the same question at least once. Someone always comes up to me and asks me what a payday engine is. Now sure this is an obscure term but a simple google search will tell you that a payday engine is just a cash advance place that specializes in payday loans. There are tons of these out there and finding the right one for you is pretty easy. You just need to factor in the different rates and penalties and find out what is perfect for you. Sure this mount sound time consuming but it really is not. You can go to one of many free sites and it will give you a nice easy to read list of all of the different rates that the different companies would offer you and the other details you need to know like loan amount and penalties. Some have really harsh penalties while others have more lenient policies because they really are there to help. I prefer to go to the companies that are more lenient even if they do have a higher rate. Because if I ever do happen to miss a payment I know that I am not going to end up owing them thousands of dollars for no apparent reason. You should factor things like this in before you commit to any one company. If you are always punctual than this is probably not a factor to you, but my life is pretty scattered and things like punctuality are pretty hard to accomplish. I occassionally forget to pay something and would really hate to see myself get screwed into owing thousands of dollars for being two days late on a payday loan. So I only take these loans when I really need them, otherwise I just pay the bills late fee.Take A Peek
