Phagocytes recognize antigen on the surface of pathogens then engulfs and destroys the pathogens with digestive enzymes. *Lymphocytes have a large nucleus which contains many copies of genes for antibody protein production. They produce antibodies that help in the defence against disease. Lymphocytes include B cells and T cells. T cells in the thymus develop the ability to recognize and destroy body cells that are infected by microorganisms. Mature B and T cells move into the lymph and blood where they help fight infection.

The importance of:
• Hygienic food preparation - This is important in order to avoid illnesses and even death due to the viruses, bacteria and parasites found in the food, which may lead to food poisoning.
• Good personal hygiene – Keeping a good hygiene helps to prevent the development and spread of infections, illnesses and bad odours. The most important way of reducing the spread of infections is by hand washing. Not covering mouth and nose will cause the rapid spread of germs to other people resulting in infection.
• Waste disposal and sewage treatment – Sewage treatment is important to protect persons from waterborne diseases such as cholera, typhoid and others that may develop from contact with untreated sewage. It is also important to practice proper waste disposal techniques and to treat sewage so as to protect the natural environment, which includes the rivers, seas and coral reefs. With proper sewage treatment and waste disposal, the economic and eco system will thrive and so too will the risk of animal illnesses be greatly lessened.

...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...

...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...

...Question 1 The first step for the simulation before moving onto the K=100 is to simulate the auction for one whole season with different strategies. From there we are able to utilize a data table function where it will simulate the expected surplus and expected revenue for the K=100 sample size. Please refer to Appendix A - Table 1-1.1 for screenshots of the tables obtained for N=3 bidders. The extensive data table is calculated for one individual’s expected surplus B1(x). Our simulation is randomized as it relies on the personal valuation each bidder gives, which is found via the =rand() formula. For question one, the optimal bidding strategy to obtain high surplus is based on obtaining the average of expected surplus in each bidding strategy column. In other words, the question is focused on finding...

...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.

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.

Connector Installations

...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...
