text: .. Another interesting tidbit from this PTR update is the updated model of Sulfuras, which now has nicer textures and more polygons but still retains a healthy bit of the cool factor the original Sulfuras did. One thing is definitely for sure -- Blizzard wanted to make the new Sulfuras very reminiscent of the old Sulfuras but updated, keeping the weapon's heart and soul. To me, the new Sulfuras is a good metaphor for Cataclysm itself..

Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells. It can affect any part of the body and is one of the leading causes of death worldwide. There are many types of cancer, and they are classified based on the type of cell they form, the location in the body, and how quickly they grow.

**Section 2: Cancer Causes**

Cancer can be caused by various factors such as genetic mutations, exposure to radiation or chemicals, viruses, and certain lifestyle choices such as smoking and excessive alcohol consumption. These factors can damage DNA, which can lead to the formation of cancer cells.

**Section 3: Cancer Treatments**

There are several treatments for cancer, including surgery, radiation therapy, chemotherapy, immunotherapy, and hormone therapy. The choice of treatment depends on the type, stage, and location of the cancer. Some treatments aim to cure the cancer, while others may be used to control symptoms or slow the growth of the cancer.

**Section 4: Genetics and Personalized Treatments**

Genetic research has shown that some people have a higher risk of developing certain types of cancer due to inherited genetic mutations. This knowledge can be used to develop personalized treatments based on an individual's genetic makeup. For example, if a person has a mutation that makes them more susceptible to a specific type of cancer, doctors can use targeted therapies that specifically attack cancer cells with that mutation.

**Section 5: Conclusion**

Cancer research is an important field that has led to significant advancements in understanding the disease and developing effective treatments. By studying the genetic basis of cancer, researchers can develop personalized treatments that are more effective and have fewer side effects. As a result, cancer survival rates have improved, and patients have a better quality of life during treatment.

**Glossary:**
- Cancer: A group of diseases characterized by the uncontrolled growth and spread of abnormal cells.
- Genetic mutations: Changes in the DNA sequence that can lead to the formation of cancer cells.
- Targeted therapies: Treatments that specifically attack cancer cells with certain genetic mutations.

**Self-Debate:** How does smoking increase the risk of developing lung cancer?

- Smoking introduces carcinogens into the lungs, which can damage the DNA of lung cells.
- Over time, this damage can accumulate and lead to the formation of cancerous cells.
- Smoking also reduces the ability of the immune system to detect and eliminate cancer cells.

**Conclusion:** Understanding cancer research and its impact on human health is essential for developing effective treatments and improving patient outcomes. By studying the genetic basis of cancer, researchers can develop personalized treatments that are more effective and have fewer side effects.

By the end of this lesson, you will have a better understanding of the Ibizan housing market and be able to apply this knowledge to similar markets.

Section 1: Factors Influencing Property Prices

**Theoretical Concept:** Supply and demand are two key factors that determine the price of a property. When there is a high demand for properties in a certain area, the prices tend to increase. On the other hand, when there is an oversupply of properties, the prices tend to decrease.

**Practical Example:** Let's say there is a new nightclub that has opened up in Ibiza, and it is attracting a lot of tourists. This increases the demand for properties in the area around the nightclub. As a result, the prices of properties in that area may increase.

**Definitions:**
- Supply: The amount of a product or service that is available in the market.
- Demand: The desire for a product or service by consumers.

Section 2: Challenges Faced by Buyers and Sellers

**Theoretical Concept:** One of the main challenges faced by buyers and sellers in the housing market is finding the right price for a property. This is because the value of a property can vary depending on its location, condition, and other factors.

**Practical Example:** Let's say a seller wants to sell their property for €500,000, but the market value of the property is only €400,000. The property may not sell because potential buyers know that they can get a similar property for less money.

**Definitions:**
- Market value: The estimated value of a property based on its features and condition.

Section 3: The Role of Real Estate Agents

**Theoretical Concept:** Real estate agents play a crucial role in the housing market by helping buyers and sellers find the right property and facilitating transactions. They have access to a network of properties and can help negotiate prices and terms.

**Practical Example:** Let's say a buyer is interested in purchasing a property in Ibiza, but they do not speak Spanish. A real estate agent can help them communicate with the seller and navigate the legal and financial aspects of the transaction.

**Definitions:**
- Real estate agent: A professional who helps buyers and sellers find and purchase properties.

Conclusion:
In this lesson, we learned about the factors that influence property prices in Ibiza, the challenges faced by buyers and sellers, and the role of real estate agents in facilitating transactions. By understanding these concepts, we can apply them to other housing markets and make informed decisions when buying or selling a property.

Glossary:
- Supply: The amount of a product or service that is available in the market.
- Demand: The desire for a product or service by consumers.
- Market value: The estimated value of a property based on its features and condition.

Lesson: Investing Basics - Understanding Dividend Yields and Volatility
Introduction:
Investing can be a great way to grow your money and achieve financial goals. However, it can also be confusing, especially for beginners. One of the key concepts that every investor should understand is dividend yields and volatility. In this lesson, we will explore what these terms mean and how they can impact your investments.
Core Value:
The core value of this lesson is to teach students how to understand and analyze dividend yields and volatility when investing in stocks or ETFs.
Section 1: Understanding Dividend Yields
Dividend yields are the payments that investors receive from the companies they own stock in. These payments are usually made on a regular basis, such as quarterly or annually. The amount of the dividend is typically expressed as a percentage of the stock's price, known as the dividend yield. A higher dividend yield means that the company is paying out more of its earnings to shareholders.
Questions and Answers:
- What is a dividend?
- Why do companies pay dividends?
- How does a company determine the amount of its dividend?
- Can a company change its dividend payment?
Section 2: Understanding Volatility
Volatility refers to the fluctuation in the price of a security over time. In other words, it measures how much the price of a stock or ETF changes from day to day or week to week. A higher level of volatility means that the price of the security is changing more rapidly and unpredictably.
Questions and Answers:
- What is volatility?
- Why do securities have volatility?
- How can I reduce the volatility of my investment portfolio?
Section 3: Low Volatility and High Dividend Yields
Investors often seek out stocks or ETFs with high dividend yields and low volatility because they provide a combination of income and stability. However, achieving both high yields and low volatility can be challenging. In general, investments with high yields tend to have higher volatility, while those with low volatility tend to have lower yields.
Questions and Answers:
- What is the Invesco S&P 500 High Dividend Low Volatility ETF?
- How does the ETF achieve a balance between high yields and low volatility?
- What are the benefits of investing in a low-volatility ETF?
Conclusion:
Understanding dividend yields and volatility is essential for any investor. By learning about these concepts, you can make more informed decisions about your investments and potentially achieve greater returns. Remember to always do your research and consult with a financial advisor before making any investment decisions.
Glossary:
- Dividend Yield: The percentage of a stock's price that is paid out as a dividend.

Topic 1: Types of Land Acquisition Strategies
There are several types of land acquisition strategies that can be used depending on the project's goals and objectives. These include:

1. Speculative Acquisition: This strategy involves purchasing land with the hope that its value will increase over time. It is often used in areas where there is expected to be high economic growth and demand for land.

2. Strategic Acquisition: This strategy involves acquiring land that is necessary for a specific project or development. It may involve purchasing land that is already developed or undeveloped.

3. Tactical Acquisition: This strategy involves acquiring land that is immediately adjacent to a company's existing property. It may be used to expand the company's operations or to prevent competitors from acquiring the land.

Topic 2: How to Choose the Right Land Acquisition Strategy
To choose the right land acquisition strategy, several factors need to be considered, including:

1. Location: The location of the land is a crucial factor in determining the appropriate acquisition strategy. For example, land in an area with high economic growth potential may be better suited for speculative acquisition, while land needed for a specific project may be better suited for strategic acquisition.

2. Market Conditions: Market conditions, such as the availability of financing and the demand for land, can also impact which acquisition strategy is best. For example, if financing is readily available, speculative acquisition may be more feasible.

3. Company Goals and Objectives: The goals and objectives of the company must also be considered when choosing a land acquisition strategy. For example, if the company's goal is to expand its operations, strategic acquisition may be the best approach.

Section 2: Practical Examples of Land Acquisition Strategies
Topic 1: Speculative Acquisition
A real estate developer decides to purchase a plot of land in a rural area that is expected to experience high economic growth. The developer believes that the value of the land will increase over time as more people move into the area and demand for housing and commercial space increases.

Topic 2: Strategic Acquisition
A company that owns a manufacturing facility decides to purchase the land adjacent to its property. The company wants to expand its operations and needs additional space for warehousing and storage. By acquiring the adjacent land, the company can expand its operations without having to relocate.

Topic 3: Tactical Acquisition
A retail chain decides to purchase a plot of land directly across from one of its stores. The company wants to prevent competitors from building a store on the land and taking business away from its existing location. By acquiring the land, the company can ensure that it has a competitive advantage in the area.

Section 3: Conclusion
Land acquisition strategies are essential tools for companies and developers looking to expand their operations or invest in new projects. By understanding the different types of land acquisition strategies and considering factors such as location, market conditions, and company goals and objectives, companies can make informed decisions about how to acquire land.

Lesson: How to Choose the Right Insurance Policy
Introduction:
Insurance is an essential aspect of life that helps individuals protect themselves and their assets from financial losses due to unexpected events such as accidents, theft, or natural disasters. This lesson will teach you how to choose the right insurance policy based on your specific needs and circumstances.
Section 1: Understanding Insurance Policies
Topic 1: Types of Insurance Policies
- There are different types of insurance policies, including auto insurance, health insurance, life insurance, home insurance, and renters insurance.
- Auto insurance covers damages to your vehicle or other vehicles in case of an accident, as well as medical expenses and legal fees.

- Home insurance covers damages to your home and belongings due to events such as fire, flood, or theft.
- Renters insurance covers damages to your possessions and provides liability coverage if someone is injured in your rental property.
Topic 2: Insurance Policies and Coverage
- An insurance policy is a contract between the policyholder and the insurance company that outlines the terms and conditions of the coverage.
- Coverage refers to the amount of financial protection provided by the insurance policy.
- Deductibles are the amount of money the policyholder must pay out of pocket before the insurance company starts covering expenses.
- Premiums are the monthly or annual payments made by the policyholder for the insurance coverage.
Section 2: How to Choose the Right Insurance Policy
Topic 1: Assess Your Needs
- Determine what types of risks you need to insure against based on your personal circumstances, such as your age, health status, income, and assets.
- Consider the potential financial losses you could face in case of an unexpected event and determine how much coverage you need.
Topic 2: Compare Insurance Policies
- Research different insurance companies and policies to find one that meets your needs and budget.
- Look for policies that offer comprehensive coverage, competitive premiums, and low deductibles.
- Read the fine print carefully to understand the exclusions and limitations of the policy.
- Compare quotes from multiple insurers to ensure you're getting the best deal.
Topic 3: Evaluate the Insurance Company
- Check the insurance company's financial stability and reputation through ratings from organizations such as AM Best, Standard & Poor's, and Moody's.
- Look for customer reviews and feedback to get an idea of the company's customer service and claim processing times.
- Choose an insurance company that has a strong track record of providing quality coverage and excellent service.
Conclusion:
Choosing the right insurance policy is an important decision that requires careful consideration of your needs, budget, and the policies available in the market. By understanding the different types of insurance policies and their coverage, comparing policies, and evaluating insurance companies, you can make an informed decision and choose a policy that provides the protection you need at a price you can afford.

Lesson: Using Nested IF Statements in Excel

**Introduction:**
In this lesson, we will learn about nested IF statements in Excel. Nested IF statements allow us to evaluate multiple conditions in a single formula. This is useful when we need to make decisions based on multiple criteria.

**Theoretical Concepts:**
- Nested IF statements are used to evaluate multiple conditions in a single formula.
- The nested IF statement consists of an outer IF statement that evaluates a condition, followed by one or more inner IF statements that evaluate additional conditions.
- Each inner IF statement returns a value if the corresponding condition is true, and the nested IF statement returns the value returned by the last inner IF statement that is true.

**Practical Examples:**
1. Suppose we have a dataset that contains the names of employees and their respective departments. We want to create a column that indicates whether an employee is eligible for a bonus based on their department and years of service.
2. We can use a nested IF statement to achieve this. The formula would look like this: =IF(AND(B2="Sales",C2>=5),"Eligible","Not Eligible")
3. In this example, the outer IF statement checks if the employee's department is Sales, and the inner IF statement checks if the employee has been with the company for at least 5 years. If both conditions are true, the employee is eligible for a bonus.

**Definitions:**
- AND: A logical operator that returns TRUE if all conditions are true, and FALSE if any condition is false.
- OR: A logical operator that returns TRUE if at least one condition is true, and FALSE if all conditions are false.

**Conclusion:**
Nested IF statements are a powerful tool in Excel that allows us to evaluate multiple conditions in a single formula. By using nested IF statements, we can make complex decisions based on multiple criteria. This skill is valuable in many fields, including finance, data analysis, and project management.

Q:

C#/WPF/Math Orienting a 3D model relative to the camera

I am working with a WPF Viewport3d.  The viewpoint is from an aircraft (call it AC1) that is constantly changing position and orientation.  In this viewport I need to draw another aircraft (call it Model2) that also changes position and orientation.  I am given the following as inputs:

AC1's Lat/Lon/Alt, Heading/Pitch/Roll
Model2's Lat/Lon/Alt, Heading/Pitch/Roll, and Azimuth/Elevation/Range relative to AC1

To position Model2 is not difficult provided I don't rotate/reposition my Perspective camera.  The camera looks in the direction (0,0,-1) and up is (0,1,0).  With that setup I can get
double X = range * Math.Cos(ConvertDegreesToRadians(elevation)) * Math.Sin(ConvertDegreesToRadians(mSATAzimDeg));
double Y = range * Math.Sin(ConvertDegreesToRadians(elevation));
double Z = range * Math.Cos(ConvertDegreesToRadians(elevation)) * Math.Cos(ConvertDegreesToRadians(azimuth));

I can then use that X/Y/Z to make a TranslateTransform3D and move the model to that position.
Where I'm running into major problems is orienting the model.  I've tried converting the Lat/Lon/Alts to ECEF space and then calculating the orientation in that space, but that messes up the position and the orientation.  I've also tried rotating the axes of the viewpoint, and then rotating Model2 around those new axes, but that isn't working either.
Does anyone have a simple algorithm to orient Model2 appropriately?  Ideally we wouldn't be rotating the camera, but rather calculate how Model2 should be oriented relative to the viewpoint.  If it seems weird that I don't want to move the camera it is because the WPF Viewport3d is acting as an overlay on top of an OpenGL window, so really I just need Model2 to be positioned and oriented relative to the WPF Viewport and don't need to move the viewpoint at all (but I can if that is easier).
Hopefully that makes sense.  If not I will try to elaborate.  Thanks for any help you can provide.

A:

So I ended up making it work, just not quite the way I wanted to...in xaml I set up this rotation for the camera
<Transform3DGroup x:Name="CameraTransformGroup">
  <RotateTransform3D>
    <RotateTransform3D.Rotation>
      <AxisAngleRotation3D Axis="0,0,1" Angle="{Binding AC1Roll, ElementName=UserControl}" />
    </RotateTransform3D.Rotation>
  </RotateTransform3D>
  <RotateTransform3D>
    <RotateTransform3D.Rotation>
      <AxisAngleRotation3D Axis="1,0,0" Angle="{Binding AC1Pitch, ElementName=UserControl}" />
     </RotateTransform3D.Rotation>
   </RotateTransform3D>
   <RotateTransform3D>
     <RotateTransform3D.Rotation>
       <AxisAngleRotation3D Axis="0,-1,0" Angle="{Binding AC1Heading, ElementName=UserControl}" />
     </RotateTransform3D.Rotation>
   </RotateTransform3D>
 </Transform3DGroup>

And for Model2 I did this rotation
<Transform3DGroup>
  <RotateTransform3D>
    <RotateTransform3D.Rotation>
      <AxisAngleRotation3D Axis="0,0,-1" Angle="{Binding Roll, ElementName=UserControl, Converter={StaticResource RadToDegConverter}}" />
    </RotateTransform3D.Rotation>
  </RotateTransform3D>
  <RotateTransform3D>
    <RotateTransform3D.Rotation>
      <AxisAngleRotation3D Axis="1,0,0" Angle="{Binding Pitch, ElementName=UserControl, Converter={StaticResource RadToDegConverter}}" />
    </RotateTransform3D.Rotation>
  </RotateTransform3D>
  <RotateTransform3D>
    <RotateTransform3D.Rotation>
      <AxisAngleRotation3D Axis="0,-1,0" Angle="{Binding Heading, ElementName=UserControl, Converter={StaticResource RadToDegConverter}}" />
    </RotateTransform3D.Rotation>
  </RotateTransform3D>
  <TranslateTransform3D OffsetZ="{Binding RelativeOffsetZ, ElementName=UserControl}"
                        OffsetX="{Binding RelativeOffsetX, ElementName=UserControl}"
                        OffsetY="{Binding RelativeOffsetY, ElementName=UserControl}" />
</Transform3DGroup>

Then in the code behind RelativeOffsetX/Y/Z are calculated by
double wXOffset = mRng * Math.Cos(mElevation * GeoConstants.DEG2RAD) * Math.Sin(mAzimuth * GeoConstants.DEG2RAD);
double wYOffset = mRng * Math.Sin(mElevation * GeoConstants.DEG2RAD);
double wZOffset = mRng * Math.Cos(mElevation * GeoConstants.DEG2RAD) * Math.Cos(mAzimuth * GeoConstants.DEG2RAD);

Matrix3D wCameraRotation = CameraTransformGroup.Value;

Vector3D wNewXyz = Vector3D.Multiply(new Vector3D(wXOffset, wYOffset, wZOffset, wCameraRotation);
this.RelativeOffsetX = wNewXyz.X;
this.RelativeOffsetY = wNewXyz.Y;
this.RelativeOffsetZ = wNewXyz.Z;

I didn't work out how to do it without rotating the camera, but by rotating the camera and the model and then running the calculated point through the rotation matrix CameraTransformGroup.Value and vector multiplication you can calculate a new offset relative to the direction the camera is facing, thus properly positioning and orienting Model2.

Lesson: Orienteering a 3D Model in C#/WPF

Introduction:
In this lesson, we will learn how to orient a 3D model relative to a camera in C#/WPF. We will use mathematical abstractions and real-world scenarios to understand the concepts involved in this process.

Section 1: Understanding the Problem
The problem we are trying to solve is to orient a 3D model (Model2) relative to another aircraft (AC1) that is constantly changing position and orientation. We are given the inputs for AC1's position and orientation, as well as Model2's position and orientation, and we need to position and orient Model2 correctly relative to AC1.

Section 2: Analyzing the Inputs
We are given the following inputs:
- AC1's Lat/Lon/Alt, Heading/Pitch/Roll
- Model2's Lat/Lon/Alt, Heading/Pitch/Roll, and Azimuth/Elevation/Range relative to AC1

We can convert these inputs into the following variables:
- AC1's Position: (lat1, lon1, alt1), (pitch1, roll1, heading1)
- Model2's Position: (lat2, lon2, alt2), (pitch2, roll2, heading2)
- Relative Position: (range, azimuth, elevation)

Section 3: Calculating the Orientation
Once we have the inputs, we can calculate the orientation of Model2 relative to AC1 using the following steps:

1. Convert the inputs to radians:
   - azimuth: ConvertDegreesToRadians(azimuth)
   - elevation: ConvertDegreesToRadians(elevation)
   - heading: ConvertDegreesToRadians(heading)

2. Calculate the angle between the relative position vector and the z-axis:
   - Use the cross product of the position vector and the z-axis to get the angle.

3. Calculate the angle between the relative position vector and the x-axis:
   - Use the cross product of the position vector and the x-axis to get the angle.

4. Calculate the angle between the relative position vector and the y-axis:
   - Use the cross product of the position vector and the y-axis to get the angle.

5. Calculate the angle between the relative position vector and the z-axis:
   - Use the dot product of the position vector and the z-axis to get the angle.

6. Calculate the angle between the relative position vector and the x-axis:
   - Use the dot product of the position vector and the x-axis to get the angle.

7. Calculate the angle between the relative position vector and the y-axis:
   - Use the dot product of the position vector and the y-axis to get the angle.

8. Calculate the angle between the relative position vector and the z-axis:
   - Use the dot product of the position vector and the z-axis to get the angle.

9. Calculate the angle between the relative position vector and the x-axis:
   - Use the dot product of the position vector and the x-axis to get the angle.

10. Calculate the angle between the relative position vector and the y-axis:
   - Use the dot product of the position vector and the y-axis to get the angle.

11. Calculate the angle between the relative position vector and the z-axis:
   - Use the dot product of the position vector and the z-axis to get the angle.

Section 4: Applying the Orientation
Once we have calculated the orientation, we can apply it to Model2 using the following steps:

1. Convert the calculated angles to radians:
   - azimuth: ConvertRadiansToDegrees(angle)
   - elevation: ConvertRadiansToDegrees(angle)
   - heading: ConvertRadiansToDegrees(angle)

2. Apply the orientation to Model2 using a RotateTransform3D with the calculated angles.

Section 5: Practical Examples
Let's consider some practical examples to illustrate the concepts learned in this lesson:

Example 1:
- Inputs:
  - AC1's Lat/Lon/Alt: (40.7128, -74.0060, 0), (0, 0, 90)
  - Model2's Lat/Lon/Alt: (40.7128, -74.0060, 10000), (0, 0, 0)
  - Relative Position: (500, 180, 0.5)

Output:
- Model2's Orientation: (90, 180, 0)

Example 2:
- Inputs:
  - AC1's Lat/Lon/Alt: (40.7128, -74.0060, 0), (0, 0, 90)
  - Model2's Lat/Lon/Alt: (40.7128, -74.0060, 10000), (0, 0, 90)
  - Relative Position: (500, 0, 0.5)

Output:
- Model2's Orientation: (90, 0, 0)

Conclusion:
In this lesson, we have learned how to orient a 3D model relative to a camera in C#/WPF. We have covered the problem statement, analyzed the inputs, calculated the orientation, applied the orientation, and considered practical examples. By following the steps outlined in this lesson, we can successfully orient a 3D model relative to a camera in various scenarios.

Changes in serum ferritin and other factors associated with iron metabolism during chronic hyperbaric exposure.
Factors related to iron metabolism were determined in 20 United States Navy divers during 8 d of air saturation-excursion hyperbaric exposures. During these simulated dives progressive and correlated increases in serum ferritin and iron occurred. No significant changes were observed in bilirubin, hemoglobin, ceruloplasmin, transferrin, copper, or total iron binding capacity. The significance of the increased serum ferritin is discussed in relation to bone marrow damage and early detection of aseptic bone necrosis.

Lesson: Understanding Iron Metabolism

Introduction:
Iron is an essential mineral that plays a crucial role in our body. It helps in the production of hemoglobin, which carries oxygen from the lungs to the rest of the body. Iron also plays a vital role in the production of energy, proper immune function, and the maintenance of cellular functions. However, too much or too little iron in the body can lead to health problems. In this lesson, we will learn about iron metabolism, its importance, and how it is regulated in the body.

Section 1: Iron Metabolism Overview

Iron metabolism refers to the processes by which the body regulates the amount of iron it needs. These processes include the absorption of iron from food, storage of iron in the body, and the release of iron when needed. The main organs responsible for iron metabolism are the liver, spleen, and bone marrow.

The absorption of iron occurs in the small intestine, where it binds to a protein called transferrin. Transferrin carries iron through the bloodstream to the liver, where it is stored as ferritin. When the body needs more iron, the liver releases it into the bloodstream.

Section 2: Factors Affecting Iron Metabolism

Several factors can affect iron metabolism, including diet, age, gender, and health conditions. For example, people who consume a lot of meat and fish are more likely to have higher iron levels than vegetarians. Women tend to have lower iron levels than men due to monthly menstruation. People with certain health conditions, such as anemia or hemochromatosis, may have abnormal iron levels.

Section 3: Regulation of Iron Metabolism

The body regulates iron metabolism through several mechanisms, including:

1. Hemodilution: When the body has too much iron, it can increase the volume of blood circulating in the body, reducing the concentration of iron in the bloodstream.

2. Iron excretion: The body can excrete excess iron through sweat, tears, and feces.

3. Ferritin: The liver stores iron as ferritin, which helps regulate iron levels in the body. When iron levels are low, the liver releases ferritin into the bloodstream, releasing iron for use by the body.

Section 4: Conclusion

Understanding iron metabolism is essential for maintaining good health. By learning about the processes that regulate iron levels in the body, we can make informed decisions about our diet and lifestyle choices. This knowledge can help us avoid health problems related to too much or too little iron in the body.

Glossary:
- Iron: A mineral that plays a crucial role in the production of hemoglobin, energy production, and immune function.
- Hemoglobin: A protein in red blood cells that carries oxygen from the lungs to the rest of the body.
- Ferritin: A protein that stores iron in the liver.
- Transferrin: A protein that binds to iron in the small intestine and carries it through the bloodstream.
- Anemia: A condition characterized by a deficiency of hemoglobin or red blood cells.
- Hemochromatosis: A condition characterized by excessive absorption of iron from the diet, leading to high levels of iron in the body.

In summary, this lesson covered the basics of iron metabolism, including its importance, the organs involved, and the factors that affect it. We also learned about the mechanisms that regulate iron metabolism and the potential consequences of too much or too little iron in the body. By understanding these concepts, we can make informed decisions about our diet and lifestyle choices to maintain good health.

Diastereopure Fe(II) and Zn(II) complexes derived from a tridentate N,N',N-bis(methyl-L-prolinate)-substituted pyridine ligand.
A series of mononuclear iron(II) and zinc(II) complexes of the new chiral Py(ProMe)2 ligand (Py(ProMe)2 = 2,6-bis[[(S)-2-(methyloxycarbonyl)-1-pyrrolidinyl]methyl]pyridine) have been prepared. The molecular geometry in the solid state (X-ray crystal structures) of the complexes [FeCl2(Py(ProMe)2)] (1), [ZnCl2(Py(ProMe)2)] (2), [Fe(OTf)2(Py(ProMe)2)] (3), [Fe(Py(ProMe)2)(OH2)2](OTf)2 (4), and [Zn(OTf)(Py(ProMe)2)](OTf) (5) are reported. They all show a meridional NN'N coordination of the Py(ProMe)2 ligand. The bis-chloride derivatives 1 and 2 represent neutral isostructural five-coordinated complexes with a distorted geometry around the metal center. Unusual seven-coordinate iron(II) complexes 3 and 4 having a pentagonal bipyramidal geometry were obtained using weakly coordinating triflate anions. The reaction of Zn(OTf)2 with the Py(ProMe)2 ligand afforded complex 5 with a distorted octahedral geometry around the zinc center. All complexes were formed as single diastereoisomers. In the case of complexes 3-5, the oxygen atoms of both carbonyl groups of the ligand are also coordinated to the metal. The stereochemistry of the coordinated tertiary amine donors in complexes 3-5 is of opposite configuration as in complexes 1 and 2 as a result of the planar penta-coordination of the ligand Py(ProMe)2. Complexes 1, 2, and 5 have an overall -configuration at their metal center, while the Fe(II) ion in complexes 3 and 4 has the opposite delta-configuration (crystal structures and CD measurements). The magnetic moments of iron complexes 1, 3, and 4 correspond to that of high-spin d6 Fe(II) complexes. The solution structures of complexes 1-5 were characterized by means of UV-vis, IR, conductivity, and CD measurements and their electrochemical behavior. These studies showed that the coordination environment of 1 and 2 observed in the solid state is maintained in solution. In coordinating solvents, the triflate anion (3, 5) or water (4) co-ligands of complexes 3-5 are replaced by solvent molecules with retention of the original pentagonal bipyramidal and octahedral geometry, respectively.

Lesson: Understanding Coordination Chemistry

Introduction:
Coordination chemistry is the study of compounds formed between metal ions and other molecules or ions. These compounds are called coordination complexes. In this lesson, we will learn about the basics of coordination chemistry, including the types of complexes, their structures, and their properties.

Section 1: Types of Coordination Complexes

1.1 What are coordination complexes?
Coordination complexes are compounds that consist of a central metal ion surrounded by molecules or ions called ligands. These ligands can be anions, neutral molecules, or even other metal ions. The ligands and the central metal ion are held together by strong electrostatic forces called coordination bonds.

1.2 How many types of coordination complexes are there?
There are two main types of coordination complexes: covalent and ionic.

1.2.1 Covalent complexes: In these complexes, the central metal ion shares electrons with the ligands. This type of bonding is usually stronger than ionic bonding, which means that covalent complexes tend to be more stable than ionic ones.

1.2.2 Ionic complexes: In these complexes, the central metal ion accepts electrons from the ligands. This type of bonding is usually weaker than covalent bonding, which means that ionic complexes tend to be less stable than covalent ones.

Section 2: Structures of Coordination Complexes

2.1 What determines the structure of a coordination complex?
The structure of a coordination complex depends on several factors, including the type of ligands, the oxidation state of the central metal ion, and the coordination number (the number of ligands surrounding the central metal ion).

2.2 What is the coordination number?
The coordination number refers to the number of ligands surrounding the central metal ion in a coordination complex. Common coordination numbers include 2, 4, and 6, but higher coordination numbers are also possible.

2.3 What is the geometry of a coordination complex?
The geometry of a coordination complex refers to the arrangement of the ligands around the central metal ion. Common geometries include linear, trigonal planar, tetrahedral, square planar, trigonal bipyramidal, octahedral, and square antiprismatic.

Section 3: Properties of Coordination Complexes

3.1 What are some common properties of coordination complexes?
Some common properties of coordination complexes include their color, solubility, and magnetic properties. These properties depend on the nature of the ligands and the central metal ion, as well as the geometry of the complex.

3.2 Why do coordination complexes have color?
Coordination complexes often have color because the energy gap between the d-orbitals of the central metal ion changes when ligands are present. This change in energy causes the absorption of light at specific wavelengths, which corresponds to the color of the complex.

3.3 Are coordination complexes paramagnetic or diamagnetic?
Coordination complexes can be either paramagnetic or diamagnetic depending on the number of unpaired electrons in the central metal ion and the nature of the ligands. Paramagnetic complexes have unpaired electrons and are attracted to magnetic fields, while diamagnetic complexes have no unpaired electrons and are repelled by magnetic fields.

Conclusion:
In this lesson, we learned about the basics of coordination chemistry, including the types of coordination complexes, their structures, and their properties. By understanding these concepts, we can better appreciate the importance of coordination chemistry in our daily lives, from the medicines we take to the electronics we use.

The 2018 mid-term elections are still more than a year and a half away, but the outlook does not look very promising for the Democratic Party. There is a laundry list of reasons the Democratic Party is in trouble. To start, there is a shortage of 2018 Senate races in states where the Democrats have a chance to win a new seat. The American left is also deeply divided. Many progressives still do not forgive the Democratic Party establishment for its treatment of Bernie Sanders in the 2016 primary. There are also a number of Senate Democrat incumbents whose seats could be in serious danger. To say the Democratic Party should be worried is a gross understatement.

According to The Hill, Claire McCaskill, a Democratic senator from Missouri, is already voicing concerns that she could face a primary election challenge by a progressive running on the idea that McCaskill has been too unwilling to take a stand against Donald Trump’s cabinet appointments.

“Many of those people are very impatient with me because they don’t think I’m pure. For example, they think I should be voting against all of Trump’s nominees and of course I’m judging each nominee on its own merit,” McCaskill said.

McCaskill could very well be right. Many Bernie Sanders supporters are wholly disgusted with the Democratic Party establishment of which McCaskill can be counted as a member in good standing. These progressives and others on the left want Democrats who are willing to take a bold stand for things like single-payer healthcare, getting corporate money out of politics, and ending what many see as out-of-control military interventionism. The left-wing of the party, and many who have “Demexited” for the Green Party or to become independents, do not have faith in Democrat senators like McCaskill, Joe Manchin of West Virginia, Heidi Heitkamp of North Dakota, and Joe Donnelly of Indiana, all of whom are from red states that voted for Donald Trump in the 2016 election. It’s hard to imagine these folks beating Republicans without a broad coalition of voters that includes anti-establishment types on the left. And if progressives mount heated primary challenges, as McCaskill predicts, it could spell doom for their chances to retain their seats.

Even Democrats once thought to be fairly secure in their jobs have reason to be concerned. Take Elizabeth Warren of Massachusetts, for example. According to Boston Globe, a January poll found that 46 percent of Massachusetts voters thought it was time to “give someone else a chance” in the 2018 election, while only 44 percent want Warren to win reelection. Her top potential contender, current Massachusetts Governor Charlie Baker, scored a 56 percent approval rating in the same poll. Warren’s approval rating was 51 percent in the poll.

Warren was once adored by the left wing of the Democratic Party, but her unwillingness to endorse Bernie Sanders in the 2016 election lost her a fair amount of support. She is now viewed by some on the left as someone willing to make bold statements but not put herself on the line when push comes to shove. A primary challenge, or perhaps even a bid for her Senate seat by Jill Stein of the Green Party, could be the nail in the coffin for her Senate career. And if the DNC is forced to spend tons of money to try and keep her seat, that will mean less funds allocated to other Senate and House elections across the country in 2018.

According to Roll Call, there are 33 Senate races in 2018. Of those races, 25 feature Democrat incumbents hoping to win another term, leaving only eight Republican incumbents whose seats are up for grabs. Of those 25 Democrat incumbents, 10 are from states won by Donald Trump in the 2016 election.

Bill Nelson of Florida

Jo Donnelly of Indiana

Debbi Stabenow of Michigan

Claire McCaskill of Missouri

John Tester of Montana

Heidi Heitkamp of North Dakota

Sherrod Brown of Ohio

Robert Casey of Pennsylvania

Joe Manchin of West Virginia

Tammy Baldwin of Wisconsin

Aside from these 10, as with the example of Elizabeth Warren above, the other 15 incumbent Democrats can not just rest on their laurels and assume a cakewalk back into their Senate seats in 2019 given divisions on the left and the apparent rightward momentum of the electorate. The House doesn’t look much better. All 435 House seats are up for re-election in 2018. According to the official House website, that means 239 Republicans and 193 Democrats will be fighting for their seats. It’s reasonable to think a fair amount of those 193 Democrats will first have to contend with primary challengers from the left before they face challengers from the right. It remains to be seen how effective the coalition of independents, Greens, and progressive Democrat Bernie supporters will be in unseating incumbent Democrats and winning primaries to go against Republican incumbents.

Despite this harsh reality, the Democratic Party establishment seems to be content with moving forward under the assumption that Donald Trump will be so awful that they’ll be able to continue business as usual and coast to victory simply because they’re not the right. This strategy has failed for years now, so it’s not really clear why it’s being tried again. The party has only worked to further ostracize people who already felt shunned by the party establishment. Perhaps the outcome will be a wholesale failure of the Democratic Party in 2018 elections so the progressive Bernie supporters, left independents, and Green coalition continues to grow, though it’s probably not the kind of “resistance” the Democratic Party is hoping for.

Lesson: Understanding Political Polarization in the United States

Introduction:
Political polarization refers to the situation where members of a society or group hold extreme and opposing views on political issues. In the United States, political polarization has been on the rise, making it difficult for the government to pass legislation and address pressing issues. This lesson will explore the causes of political polarization in the United States, its effects, and possible solutions.

Section 1: Causes of Political Polarization in the United States

1.1. Theoretical Explanations
One of the leading theories explaining political polarization is the "sorting" theory. This theory suggests that people tend to sort themselves into like-minded groups based on their social, economic, and cultural backgrounds. As a result, individuals end up living in areas where they share similar political views with their neighbors.

1.2. Practical Explanations
Another cause of political polarization is the way political parties are organized. In the United States, political parties are responsible for selecting candidates for elected offices. As a result, candidates tend to align themselves with their party's ideology to secure the nomination. This leads to a situation where politicians become more extreme in their views to appeal to their party's base.

Section 2: Effects of Political Polarization

2.1. Legislative Gridlock
Political polarization makes it difficult for the government to pass legislation. When politicians hold extreme views, they tend to disagree on most issues, making it challenging to find common ground.

2.2. Lack of Compromise
Polarized politicians find it hard to compromise on issues. They tend to see things in black and white terms, making it difficult to find middle ground.

2.3. Increased Partisanship
Polarization leads to increased partisanship among politicians and voters. People tend to support their party regardless of the issue at hand, making it challenging to find solutions to problems.

Section 3: Possible Solutions

3.1. Redistricting Reform
Redistricting reform aims to reduce the impact of gerrymandering, where politicians draw electoral boundaries to favor their party. By doing so, it would make it harder for politicians to sort themselves into like-minded groups.

3.2. Ranked Choice Voting
Ranked choice voting allows voters to rank candidates in order of preference. If no candidate gets a majority of the votes, the candidate with the least number of votes is eliminated, and their votes are redistributed to the remaining candidates. This system encourages politicians to reach across the aisle and appeal to voters from different parties.

Conclusion:
Political polarization is a significant problem in the United States. It makes it challenging for the government to address pressing issues and leads to increased partisanship. However, there are possible solutions that could help reduce polarization and encourage politicians to work together. By understanding the causes and effects of political polarization, we can work towards finding solutions that promote compromise and cooperation.
