question:
There are various places you can go to for an HIV test, including: 1 sexual health or genitourinary medicine (GUM) clinics. 2 clinics run by charities like the Terrence Higgins Trust. 3 some GP surgeries. 4 some contraception and young people's clinics. 5 local drug dependency services. 6 an antenatal clinic, if you're pregnant. By six months after infection, most people will turn positive on an antibody test. Because of this, antibody testing isn't appropriate for people who are worried they may have been very recently exposed to HIV or herpes. If this is the case, talk to your doctor about what type of testing may be right for you. The human immunodeficiency virus -- HIV -- causes acquired immunodeficiency syndrome, or AIDS. You can be infected with HIV for many years and show few if any symptoms before the development of AIDS. However, people who are HIV-infected can transmit the virus to other people. Authors of a study published in 2005 in the Journal of Infectious Disease reported that the highest rate of HIV transmission occurs when an individual is newly infected but does not test positive for HIV. If your first test is done in a testing lab and it's positive, the lab will conduct the follow-up testing, usually on the same blood sample as the first test. Talk to your health care provider to see what type of HIV test is right for you. If you test negative on an HIV RNA test after two weeks of possibly being exposed, you are very likely HIV-negative. If you test negative on a 4th generation rapid test or lab assay that detects HIV antigens (part of the HIV virus) in addition to antibodies after three or four weeks after possibly being infected, you are very likely HIV-negative. And if you test negative on an antibody test taken 3 months or longer after your last possible risk of possible exposure to HIV, you are likely HIV-negative. The person who gives you your HIV test will have additional information about the test's window period.. For this reason, we recommend that people who are having sex get tested routinely every 3 months. Routine testing is painless and ensures that if you do get infected, you can start treatment right away. If a person has been exposed to HIV, there is a period by which an HIV test cannot deliver an accurate response known as the window period. If a person has been exposed to HIV, there is a period by which an HIV test cannot deliver an accurate response known as the window period. How long do HIV test results take? How are they reported? How long do results take? Rapid HIV tests can give results in 1560 minutes, or on the same day. 'Rapid' refers for the time taken for the results and not the time since exposure that a test can be used. If samples are being sent to another lab, results can take a few days or a few weeks. Rapid blood tests put a pin-prick of blood on a testing strip. This test takes about 15-20 minutes so you can get the results whilst you wait. Some rapid tests also work on oral samples rather than blood. Although they are sometimes called saliva tests this is not accurate. 20-45 days after infection, HIV antibodies can be detected by this type of test RNA tests show a positive result based on the presence of the virus. These tests are more expensive than antibody tests, so are not offered in as many places. An HIV test can show infection in most people within 3 months (average of 25 days to build HIV antibodies). A 3 month negative test may be repeated at the 6 month point to pick up on the rare situations in >. ... ...risky behavior and that you were not exposed to any HIV-infected fluids. The only way to know for sure whether you have been infected is to get tested. You should wait for 3 months after a possible exposure. Then get an HIVblood test (see Fact Sheet 102 ). You might feel that you have been exposed toHIV by sharing needles, an accident, or unsafe sexual activity. In these cases, talk to your health care provider immediately . Query: how long does it take hiv to show in blood test
answer:
It takes three or four weeks hiv to show in blood test.

question:
So you might as well redefine your question as How many Ships does the US navy have? IF you want to know the real answer to how many Aircraft Carriers?... you cannot redefine the question to mean something else. We have 10 Carriers. The Japanese Navy had 25 carriers of all types; 1 was laid up damaged, another beached and capsized, 20 were lost to enemy action. The French Navy, as noted above, had 1 carrier, converted to an aircraft transport in 1944. This count is for commissioned naval vessels designated as aircraft carriers only. Nimitz class aircraft carrier design. The more recent Nimitz Class carriers (CVN72-CVN76) have a displacement of 102,000t when fully loaded. They have a length of 317m and beam of 40.8m. The carrier reaches a maximum speed of over 30kt, and accommodates a complement of 3,184 personnel (with 203 officers); 2,800 aircrew (with 366 officers); and 70 flag (with 25 officers). Aircraft Rep. Paul Ryan (R-WI) on Wednesday defended his budget's call to increase military spending by complaining that the U.S. has only 10 aircraft carriers and that the U.S. Army is smaller than it was in 1945 and the U.S. Navy is smaller than it was during World War I. List of aircraft carriers in service. This is a list of aircraft carriers which are currently in service, reserve, under construction, or being rebuilt. An aircraft carrier is a warship with a full-length flight deck, hangar and facilities for arming, deploying, and recovering aircraft. The list only refers to the status of the ship, not availability or condition of an air wing. This includes helicopter carriers and amphibious assault ships, which are vessels whose primary purpose is to carry, arm, deploy, and recover aircraft. Statistically, one can take the numbers of carriers in action per month during the period and come up with a composite carrier's profile of operating numbers: Flights: 2755; action sorties 1043; combat losses: 61; combat operational losses: 26; non-combat related losses: 28; for a total of 115 aircraft lost in a 12 month period. In the United States Navy, these consist of ships commissioned with hull classification symbols CV (aircraft carrier), CVA (attack aircraft carrier), CVB (large aircraft carrier), CVL (light aircraft carrier), CVN (aircraft carrier (nuclear propulsion)) and CVAN (attack aircraft carrier (nuclear propulsion)). There are 11 aircraft carriers currently in service in the U.S. fleet USS Enterprise (CVN-65): 85,600 ton unique nuclear-powered supercarrier, commissioned 25 November 1961.

This absence of sufficient seapower sets the stage for trouble reaching far beyond the region, raising the larger question of how the U.S. is planning future naval forces. Aircraft carriers are an instructive example. In the 2007 Defense Authorization bill, Congress wrote into law that we must not go below eleven. Since December 2012, this has been lowered to ten so that USS Enterprise could be retired before USS Ford's 2016 commissioning. Query: how many aircraft carriers usa have
answer:
The United States has currently 11 aircraft carriers in service.

question:
A net energy meter keeps track of the all the power your solar system produces. Any solar energy that you do not use simultaneous with production will go back into the electrical grid through the meter. At night or on cloudy days, when your system is not producing more than your building needs, you will consume electricity from the grid as normal. Touted as a promising alternative energy source for decades, solar panels crown rooftops and roadside signs, and help keep spacecraft powered. But how do solar panels work? Simply put, a solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity. Solar panels actually comprise many, smaller units called photovoltaic cells. (Photovoltaic simply means they convert sunlight into electricity.) Many cells linked together make up a solar panel. Each photovoltaic cell is basically a sandwich made up of two slices of semi-conducting material, usually silicon the same stuff used in microelectronics. To work, photovoltaic cells need to establish an electric field. In addition, the nation's solar capacity by the end of 2016 is projected to be double what it was at the beginning of 2015, while costs continue to decline and panel efficiencies increase. The question many people have is: How exactly do those panels work? The diagram above illustrates the operation of a basic photovoltaic cell, also called a solar cell. Solar cells are made of the same kinds of semiconductor materials, such as silicon, used in the microelectronics industry. For solar cells, a thin semiconductor wafer is specially treated to form an electric field, positive on one side and negative on the other. When light energy strikes the solar cell, electrons are knocked loose from the atoms in the semiconductor material. What's the biggest difference between how a plant captures light energy and how we do it with solar cells? We wish we could do what plants do because plants absorb the light, and [they use] that electron to change a chemical bond inside the plant to actually make fuel. Could you do artificial photosynthesis and emulate a plant? We would love to be able to make a solar cell that instead of making electricity makes fuel. That would be a very big advance. Solar panel conversion efficiency, typically in the 20% range, is reduced by dust, grime, pollen, and other particulates that accumulate on the solar panel. Solar photovoltaic (PV) panels are based on a high-tech but remarkably simple technology that converts sunlight directly to electricity < PREVIOUS: The Solar Resource | NEXT: Rooftop Solar Panels > It's an idea that has been around for well over a century. Sun Activation. 1 Photons bombard and penetrate the cell. 2 They activate electrons, knocking them loose in both silicon layers. 3 Some electrons in the bottom layer sling-shot to the top of the cell. 4 These electrons flow into metal contacts as electricity, moving into a circuit throughout a 60-cell module. How Solar Panels Work How a PV cell makes electricity Under the sun, a photovoltaic cell acts as a photosensitive diode that instantaneously converts light but not heat into electricity. Basic Steps in Solar Energy Generation and Transmission. 1 Sunlight hits the solar panels, and creates an electric field. 2 The electricity generated flows to the edge of the panel, and into a conductive wire. 3 The conductive wire brings the electricity to the inverter, where it is transformed from DC electricity to AC, which is used to power buildings. Query: how does solar panel work
answer:
A solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity.
