Document Summary

Anemia a group of disorders characterized by a deficit of red blood cells. Relative anemia normal total red cell mass with disturbances in regulation of plasma volume. Absolute anemia actual decrease in numbers of red cells. Chronic: in -creased destruction (hemolytic, de -creased production. * a good definition would be a decrease in oxygen carrying capacity , rather than just a decrease in red blood cells, because you need to have enough blood cells that function , and not just enough blood cells. Causes of decreased production of rbc"s working to full capacity, not enough rbc"s are made. Bone marrow is the factory for rbc"s if the factory is broken or not. The kidneys produce erythropoietin , which stimulates the manufacture and maturation of rbc"s in the bone marrow. They send orders to the bone marrow factory. Without orders the factory cannot produce its product. the factory to make its product. Iron, b12, and folate are building materials required by.

John, a healthy twenty-eight year old electrical engineer, was driving home from work one evening when he experienced sudden stabbing pain in his right pectoral and right lateral axillary regions. He began to feel out of breath and both his respiratory rate and heart rate increased dramatically. As luck would have it, John passed a hospital each day on his way home and was able to get himself to the hospital’s emergency room.

The emergency room physician listened to John's breathing with a stethoscope and requested blood gas analysis and a chest x-ray. John answered a few of the doctor's questions. The doctor noted that John had no history of respiratory problems but was a heavy smoker.

After viewing the chest radiograph, the doctor informed John that he had experienced a spontaneous pneumothorax, or what is commonly called a collapsed lung. The doctor explained that a hole had opened in John's right lung and that this hole had allowed air to leak into the cavity surrounding the lung.

Then, as a result of the lung's own elastic nature, the lung had collapsed. The doctor said he could not be certain of the cause of the pneumothorax, but smoking cigarettes had certainly increased the likelihood of it happening. He told John he was fortunate the pneumothorax was small, which meant that relatively little air had escaped from the lung into the surrounding cavity, and it should heal on its own.

He instructed John to quit smoking, avoid high altitudes, flying in non-pressurized aircraft, and scuba diving. He also had John make an appointment for a re-check and another chest x-ray.

Case Background

The pneumothorax decreases the efficiency of the respiratory system, which in turn results in decreased blood oxygen concentration, increased respiratory rate, and increased heart rate. If the pneumothorax is small, the air that escapes into the pleural cavity can be reabsorbed into the lung once the opening has sealed shut. If the pneumothorax is large, a needle or chest tube may have to be inserted into the pleural cavity to draw the air out and allow for the re-expansion of the lung.

Questions

1. Define the following terms and explain how they may have been affected by John’s spontaneous pneumothorax.

a. Visceral pleura

b. Parietal pleura

c. Pleural cavity

2. As a result of a pneumothorax, the lung tissues recoil, and the lung collapses. Explain how recoil and collapse are prevented in a healthy lung?

3. How does elastic recoil function in breathing?

4. Why was John instructed to avoid high altitudes and flying in non-pressurized aircraft?

A Client may have 1 or more Accounts. An Account is characterized by:
• Account number: character on 10 positions,
• Balance: Numerical with 3 positions after the comma,
• Flow rate threshold: Numeric with 3 positions after the decimal point,
• Balance date: Date.

• Expiration date: Date

QUESTIONS :
1. Give the class diagram.
2. Give the different tables indicating the relationships between the different Tables.
3. Write a Withdraw function in PL/SQL that takes an account number as an argument and a withdrawal amount then performs the withdrawal operation by modifying the balance in the Account table. Note the withdrawal can only be made if balance – amount > threshold. The function returns the new balance after the withdrawal.
4. Write a Payment function in PL/SQL that takes as argument a number of the account and an amount then updates the balance in the Account table. The function returns the new balance after withdrawal.
5. Write a trigger to raise an exception in the event of a decrease in the balance of an account whose status is “blocked”.
6. To archive the history of Account table update operations, create a History table (NumCpt, operation_date, operation_type). Write a trigger allowing, after the execution of each operation on Account, to add a tuple regarding this operation to the History table.
7. Write a Withdrawal_Card function in PL/SQL which takes as argument a card number card and an amount then updates the balance in the Account table. Function returns the new balance after the withdrawal. The withdrawal can only be made if the balance allows him and the ceiling.
8. Write a trigger allowing to raise an exception in the case of an expiration of the date of a card.
9. Write a procedure that allows each Bank to display the branch code, wording of the Agency, name and balance of the Client having the largest balance in this Agency.
10. Write a PL/SQL procedure to display for all Agencies the three first highest Account balances, if there is not only one balance then display for the second and third, the same value as the first; and if he only two different balances exist, so display the same value for the third than the second.

Why Adjustable Height Workstations are a healthy alternative?

Embracing the new adjustable height desks will be beneficial for employees of all heights. These desks are essential for proper ergonomics and can help alleviate back pain, neck pain, and eyestrain. The adjustable workstations allow users to stand or sit at their desks. This increases productivity by reducing fatigue and time wasted on breaks. The best part is that they are affordable too!

Adjustable height workstations are the most sensible choice for any office with mixed heights of employees. These workstations can be adjusted to suit our needs which increases productivity, alleviates back pain, neck pain, and eyestrain. Adjustable height desks are a great way for people of different heights to work comfortably. They allow the user to adjust the height of their work area by using a crank or a hydraulic piston. The desk can go from sitting down to standing up and many desks have a mobile base that can be moved as needed.

An Adjustable computer desk is an investment that will last for years and will give you the comfort you need to work productively. Adjustable height workstations are the way to go. They allow users of different heights to work comfortably, and they can be used by people who have limited mobility. An adjustable height desk will increase your productivity because you'll be able to work comfortably in an ergonomic position. With this desk, you can switch positions often without worrying about aches and pains from sitting for too long in a single position.

Adjustable computer desk are a great solution if you're experiencing pain in your lower back or neck from working in a standard seated position all day long. Sitting at the same level as your computer screen will decrease the strain on these areas and help prevent future injuries. Adjustable height workstations are great for those who are looking to optimize their workspace. To accommodate different heights, simply adjust the height of the desk.

The best adjustable height desks allow you to adjust the height of your desk’s top surface and keyboard platform independently, giving you more ergonomic positioning options than ever before. Some people like to make their desks lower to make it easier for them to stand up and take a break now and then. Other people prefer higher desks so they can sit more comfortably while they work on things like spreadsheets.
