Problem: Write an article based on this summary: Choose the right tunneling machine for the job. Get the machine into position. Erect tunnel supports as the machine bores through. Spray concrete on the excavated walls between the support rings.

Answer: Tunnel boring machines, called TBMs for short or “moles,” feature circular plates on the front called shields. Disc-shaped cutters on the shield tear through rock and dirt, which passes through openings in the shield onto a conveyor belt inside the TBM that deposit it behind the machine.  The types of TBM shields vary according to whether the mole is to dig into soft, wet ground or hard rock. Shield diameters range from Aker Wirth’s 26.3-foot (8.03 m) shield on its TBM used for Switzerland’s Linth-Limmern power stations to Hitachi Zosen’s “Big Bertha,” with its diameter of 57.5 feet (17.5 m).  Moles designed to dig tunnels below the water table also feature chambers at the front to pressurize the ground being dug through. For large jobs, multiple TBMs may be called for. The Channel Tunnel required 11. For a surface level tunnel, this is no problem. If the tunnel is to be bored deep underground, an access shaft, usually circular, is drilled and lined with concrete. The TBM is lowered into it, and the tunnel is excavated from that point.  For long tunnels, multiple access shafts are drilled. When the tunnel is finished, the access shafts may become ventilation shafts and/or emergency exits. If they are not so employed, they are left in place for the life of the tunnel. Segments of pre-cast concrete are erected behind the TBM to form a ring at pre-determined intervals. The sprayed concrete, or shotcrete, coats and stabilizes the tunnel walls. The shotcrete may include steel or polypropylene fibers to strengthen it, much the way steel rebar is used to strengthen cast concrete.  The shotcrete also contains an accelerant to help it stick to the tunnel walls and dry quickly.


Problem: Write an article based on this summary: Look for signs of fatigue. Be aware of persistent fever. Ask your child if they are experiencing bone pain. Look for easy bruising and bleeding. Feel for soft, small lumps under the skin. Watch out for a loss of appetite. Keep track of any weight loss.Chronic battle of the body against leukemia triggers a cascade of inflammatory cells. Be aware if your child is experiencing night sweats. Look for lumps in the groin, underarms, and neck. Identify any pains or aches on the left side of the abdomen.

Answer: Fatigue is the most common symptom. Paleness of the face and skin and difficult of breathing with mild exertion may accompany fatigue. These symptoms indicate that the red blood cells do not carry sufficient amounts of oxygen to the rest of the body. The lungs, other vital organs, and muscles compensate for less oxygen by working more diligently. This is a very taxing process to sustain and causes general feeling of fatigue. Fever actually protects the body from harmful processes within. The constant fighting of the body against leukemia cells trigger persistent fever. The bone marrow is the soft tissue core inside the bone. Bone pain is a result of the saturation of bone marrows with leukemia cells. Easy bruising , frequent bleeding of gums and nose, pinpoint red spots in the skin. These are symptoms of low amounts of normal platelet in the body. Soft, small lumps may be found in any part of the body. The lumps are by-products of leukemic cells seeping under the affected area. The spleen is the graveyard for dead blood cells. Leukemia increase the death rate of blood cells and congest the spleen. Consequently, the spleen becomes enlarged. The close proximity of the spleen to the stomach plays a role in loss of appetite. The enlarged spleen presses on the stomach to mimic a feeling of fullness. This explains the loss of appetite. One inflammatory cell is named tumor necrosis factor (cachectin). Cachectin is responsible for weight loss. Fever is a response of the body against harmful leukemia cells. Chronic fever alters the ability of the brain to regulate body temperature. The brain’s faulty regulatory process perceives the normal body temperature to be too hot and uses night sweating as a means of releasing heat. The lumps signify swelling of the lymph glands. The lymph glands are the policemen of the body. They detain unwanted bacteria, virus, and foreign substance such as cancer cells and prime them for removal. In this case, lymph glands trap leukemia cells and try to eliminate them. The spleen becomes too stretched and enlarged that pain is produced. This is often complained in the left side of the abdomen where the spleen is usually located.


Problem: Write an article based on this summary: Try quad pulls. Try downward facing dog. Stand in tree pose. Experiment with bow pose.

Answer: Bend your left knee and pull your left leg behind your body, using your left hand to support it. Reach your right arm toward the ceiling, as far as it will go. After your arm is lifted, raise up onto your right toes and balance there.  When you’ve got a good stretch on your left side, switch and do the same thing on your right side. Alternate back and forth. Do ten rounds on each side. From a standing position, fold your body over at the waist and allow your hands to touch the floor. Walk your hands forward until your body resembles that of an upside down letter V.  Your hands should be shoulder-width apart. Your fingers should be spread wide. Keep your feet hips-width distance apart. Try to touch your heels to the floor. Stand straight up with your feet together. Lift your right foot and tuck it into the space right above your left knee, with your right knee facing out. Put your palms together in front of your heart.  Stand in this position for ten seconds, then switch sides. When your feet are together, your big toes should be touching, and your heels should be slightly apart. Make sure your weight is evenly balanced. Don't let your foot rest on your knee, it can damage your joints. Lie on your stomach with your arms running beside your body – make sure to keep your palms face up. Bend your knees and grab your ankles with your hands.  When you breathe in, try to lift your knees and thighs even further away from the floor. Stay here for five seconds. Take a break, then try this pose two more times.


Problem: Write an article based on this summary: Discuss why this role turns you on. Set your limits. Establish a safe word.

Answer:
Once you have decided on the roles you want to play, it is important that you and your partner discuss exactly what it is about this scenario that turns you both on. This will help to ensure that the fantasy plays out the way you want. For instance, a lot of people may have a student/teacher fantasy, but some people may be into a punishment scenario that involves rulers and spankings, while other people might be into plaid skirts and forbidden affairs. Before you and your partner get lost in character, it is important that you both know what you are comfortable doing. This is especially true if you are playing with a punishment scenario. For example, you may find that a light spank turns you on, but choking is off the table. Alternatively, anal sex or certain sex toys may be off limits for you.  Have an open and honest conversation with your partner. If you are shy about discussing these details in person, you could establish the rules electronically via email or text. In order to ensure, that things don’t get carried away while role playing, you and your lover should establish a safe word prior to beginning. When this word is spoken it will bring the role play to a halt and signals that someone is uncomfortable with the situation. Choose a word that is not likely to come up naturally during the role play scenario.
