...Vitamin B12, the energy vitamin Vitamin B12 is a powerhouse. It helps make DNA, nerve and blood cells and is crucial for a healthy brain and immune system. B12 is only found in animal products like eggs, meat, shellfish, and dairy. It is estimated that up to 15% of people don't get enough of this essential nutrient Who's a risk of deficiency Vegans, vegetarians, along with people living with celiac disease or other digestion problems. Age Adults over 50 will also be a risk because as we age stomach acid production is reduced, resulting in one in 31 adults over 50 becoming deficient. Some people over 75 lose the ability to absorb vitamin B12 from food and must take supplements if the deficiency is severe may recommend oral drops or injections. Babies can get it too In infants, vitamin B12 deficiency is serious and can lead to anaemia, problems with movement, difficulty reaching developmental milestones, and failure to thrive. Low B12 levels are rare in infants but can happen if a breastfeeding Mother is a vegan who doesn't take vitamin B12 supplements, and breast milk is the only source of nutrition. Or if a baby is fed a strict diet free of any animal products. Digestive problems can cause it People who deal with digestive issues such as colitis, Crohn's disease, inflammatory bowel disease, are at a higher risk of a B12 shortage because digestive problems can make absorbing the nutrient more difficult. Celiac disease sufferers can also have problems with absorption. If...

...1. According to Mayo Clinic, it takes time for the body to develop antibodies towards the virus. No tests may be taken before this time period as blood samples etc. would return negative when individuals may actually have acquired HIV. 2. (a) There are approximately four main different lab tests that may be done to figure out if an individual has HIV; CD4 count, viral load, drug-resistance testing, and testing for STI’s. Others include blood cell count, kidney and liver function tests, blood glucose and blood fat levels, and hepatitis testing. o CD4 Count – The lower the CD4 count there is in a blood sample, the greater the risk there is for HIV already damaging the immune system. o Viral Load – Measure how much virus is in the bloodstream....

...Because when we input text, we do not look at contents except for input component. Accordingly, reducing the occlusion with the almost transparent keyboard will be feasible. 6.2 Orientation of keys Orientation of keys may change the learning cost of the QAZ Keyboard, thus is one of our future work. Note that this paper presents QAZ Keyboard with keys oriented to users, i.e., the letter on the top of a key is placed with the same orientation in both keyboards as shown in Figure 1 and 2. However, this arrangement destroys the orientation relationships between the entire keyboard and keys of the conventional QWERTY layout. While there are some alternatives with the orientation of the keys, we believe that one such feasible alternative is to rotate the keys by 90 degrees counterclockwise so that, for example, 'Q' is displayed as ' Q '. 7 CONCLUSION We have presented a QAZ Keyboard, a QWERTY keyboard with one-handed thumb for a large touchscreen. To design the keyboard, we rst conducted exper- iments to investigate pointing performance on a large mobile touchscreen using one-hand thumb. The results show that vertically long areas around the center of the touchscreen will be suitable to place a keyboard in terms of accuracy...

...Vitamin B12 is a water soluble vitamin commonly present in animal protein. It is important for DNA synthesis, synthesis of neurotransmitters, formation of myelin sheath and erythropoiesis [3]. Daily requirement of vitamin B12 is approximately 1 to 2 mcg [4]. Vitamin B12 deficiency commonly occurs due to insufficient dietary intake or poor absorption from gastrointestinal tract. Dietary deficiency is usually seen in vegans, alcoholics and elderly people,[5] whereas malabsorption may occurs in patients suffering from hypochlorhydria, decreased output of gastric intrinsic factor or disorders of small intestines[6]. Further the requirements of vitamin B12 are increased in case of pregnant and breast feeding women, patients with autoimmune disorders, or persons with HIV infection which puts them at high risk for...

...VITAMIN B12 DEFICIENCY Vitamin B12 is needed for many of the body's vital functions, including the production of red blood cells and cell metabolism. B12 deficiency can lead to anemia (anemia) and severe damage to the nervous system. The body can not produce vitamin B12 itself, so therefore we have to get us in the vitamin through food, primarily through eating meat, fish, eggs and dairy products. The need of B12 vary from person to person, partly due to gender and age, but the National Food Administration recommends a daily intake of 2.0 mcg for adults and 2.6 mcg for pregnant women. SYMPTOMS OF B12 DEFICIENCY B12 helps with the formation of new cells in the body and therefore a lack of B12 in principle produce symptoms of any organ. The first cells affected are usually the renewed frequently, such as red blood cells and the cells on the tongue in the mouth and intestine. It can lead to heavy burning, cracks in the mouth, nausea, lack of appetite and diarrhea. Anemia makes the body does not get enough oxygen and may initially lead to symptoms such as fatigue, weakness and dizziness. It is also common to feel short of breath and heart palpitations when you make an effort. Severe anemia may in some cases give angina and leg pain. Nervous system symptoms include loss of sensation and vibration sense, numbness and tingling in the hands and feet, impaired gait and balance, as well as psychological symptoms such as sadness, depression, memory problems and dementia. The symptoms...

...Exercise One Nt1310 Week 1 In: Computers and Technology Exercise One Nt1310 Week 1 NT1310:Week 1 Telecommunications By: Kenneth Martin You are an IT Network Specialist and are required to develop the design of the company’s telephone system for its new building which will begin construction in a few months. In order to get a background which will help when developing the new system, your supervisor asked you to research the current Plain Old Telephone Service (POTS) currently used by the company. You must research the system components and report back to your supervisor , the Telecommunications Manager, within a week. 1. Describe a local land line phone system based on the following Landline Telephone Components: a. Local Loop a local loop is the wired connection from a telephone company's central office in a locality to its customers' telephones at homes and businesses. This connection is usually on a pair of copper wires called twisted pair. The system was originally designed for voice transmission only using analog transmission technology on a single voice channel. Today, your computer's modem makes the conversion between analog signals and digital signals. With Integrated Services Digital Network (ISDN) or Digital Subscriber Line (DSL), the local loop can carry digital signals directly and at a much higher bandwidth than they do for voice only. b. Central Office In telephone communication in the United States, a central office (CO) is an office in a locality...

...NT1310 Unit 6 Exercise 1 Luz Garcia 7/22/14 Connector Installations Twisted-pair cable: Step 1: Measure the cable you want to put ends on and trim it to the proper length using the cable cutter. Step 2: Use the cable stripper to strip about 1.5" of the jacket from the end of the cable. Then, rotate the stripper around the cable twice. This will cut through the jacket. Step 3: Remove the stripper from the cable and pull the trimmed jacket from the cable, exposing the inner conductors. If a jacket slitting cord (usually a white thread) is present, separate it from the conductors and trim it back to the edge of the jacket. Step 4: Untwist all the inner conductor pairs and spread them apart so that you can see each individual conductor. Step 5: Line up the individual conductors so that the color code matches the color-coding standard you are using. Step 6: This step includes two points. First, trim the conductors so that the ends are even with each other, making sure that the jacket of the cable will be inside the connector. Second, the total length of exposed connectors after trimming should be no longer than 0.5" to 0.625". Step 7: Insert the conductors in the connector, ensuring that all conductors line up properly with the pins as they were in the previous step. If they don't line up, pull them out and line up. Do this carefully, as it's the last...
