text: Internal bleaching, also known as non-vital bleaching, is provided to lighten a tooth which has become darkly discolored as a result of root canal therapy. A chemical oxidizing agent is placed within the crown of the tooth, left for a timed period, and then removed. This procedure may be done entirely in our office in one visit or the patient may be sent home so that the treatment may take effect over a period of days. They then return to the office to have the bleaching agent removed. Depending upon the discoloration of the tooth, either procedure may be performed one or more times to achieve the desired aesthetic result.. Practice Limited to Endodontics.

**Lesson:** Introduction to Endodontics

**Section 1: What is Endodontics?**

Endodontics is a branch of dentistry that deals with the study and treatment of the dental pulp and surrounding tissues. It involves diagnosing and treating problems related to the root canal system, such as infections, inflammation, and injuries.

**Section 2: Why is Endodontics important?**

Endodontics is important because it helps save teeth that would otherwise be lost due to infection or injury. By removing damaged pulp and cleaning out the canals, the tooth can be preserved and function properly again.

**Section 3: How does Endodontics work?**

The process of endodontic treatment begins with a thorough examination of the tooth to determine if it is a good candidate for treatment. If it is, the dentist will create an opening in the crown of the tooth to access the pulp chamber. The pulp, nerve, and blood supply are removed, and the canals are cleaned and shaped using specialized instruments. After the canals are cleaned, they are filled with a rubber-like material called gutta-percha to seal them off from the outside world. Finally, a crown or other restoration is placed on the tooth to protect it from further damage.

**Section 4: What happens after Endodontics treatment?**

After endodontic treatment, patients may experience some discomfort, but this can usually be managed with over-the-counter pain medication. It is important to follow the dentist's instructions for care and to schedule regular checkups to monitor the health of the treated tooth.

**Glossary:**
- Dental Pulp: The soft tissue inside the tooth that contains blood vessels, nerves, and connective tissue.
- Root Canal: The hollow space within the root of a tooth that contains the pulp.
- Gutta-Percha: A rubber-like material used to fill and seal the root canals during endodontic treatment.

**Conclusion:**

Endodontics is an important branch of dentistry that helps preserve teeth that would otherwise be lost due to infection or injury. By understanding the basics of endodontic treatment, patients can make informed decisions about their oral health and understand the importance of preserving their natural teeth.

Lesson: Introduction to Geothermal Energy

## Section 1: What is Geothermal Energy?

Geothermal energy is a type of renewable energy that comes from the heat within the Earth's core. It is a clean and sustainable source of energy that can be used for electricity generation, heating, and cooling. This lesson will introduce you to the basics of geothermal energy, including its definition, how it works, and its benefits.

**Definition:** Geothermal energy is defined as the thermal energy that is generated and stored in the Earth's crust, mantle, and core. It is a type of renewable energy that can be harnessed for human use.

**How it works:** Geothermal energy works by tapping into the natural heat that is generated within the Earth's core. This heat is transferred to the Earth's surface through conduction, convection, and radiation. Geothermal power plants use this heat to produce steam, which drives turbines and generates electricity.

**Benefits:** There are several benefits to using geothermal energy, including:

- It is a clean and sustainable source of energy that does not produce greenhouse gas emissions or air pollution.
- It is available 24/7 and can be used to provide a reliable source of electricity.
- It can be used for heating and cooling buildings, reducing energy consumption and costs.
- It can be used to produce geothermal direct-use heat, which can be used for industrial processes, agriculture, and horticulture.

## Section 2: How is Geothermal Energy Harnessed?

There are two main ways that geothermal energy can be harnessed: through geothermal power plants and direct-use applications. In this section, we will explore both of these methods in more detail.

**Geothermal Power Plants:** Geothermal power plants use the heat from the Earth's core to generate steam, which drives turbines and generates electricity. These power plants can be located near volcanic areas, where there is an abundance of geothermal resources, or they can be built in areas with lower geothermal resources but with access to other renewable energy sources, such as solar or wind power.

**Direct-Use Applications:** Direct-use applications of geothermal energy involve using the heat from the Earth's core for heating and cooling buildings, providing hot water, and even growing crops. This can be done through the installation of geothermal heat pumps, which transfer heat from the ground into buildings, or by drilling geothermal wells, which can provide a reliable source of hot water for heating and cooling.

## Section 3: Geothermal Energy in the Real World

In this section, we will explore some real-world examples of how geothermal energy is being used today.

**California:** California is home to the largest geothermal power plant in the world, the Geysers, which produces enough electricity to power over 1 million homes. The state also has over 100 geothermal power plants, which together produce enough electricity to meet the needs of over 2 million homes.

**Iceland:** Iceland is known for its geothermal energy, which provides over 25% of the country's electricity needs. The country has over 25 geothermal power plants, which use the heat from the Earth's core to generate steam and drive turbines.

**El Salvador:** El Salvador is another country that has embraced geothermal energy as a source of electricity. Over 20% of the country's electricity comes from geothermal power plants, which use the heat from the Earth's core to generate steam and drive turbines.

## Conclusion

Geothermal energy is a clean and sustainable source of energy that can be used for electricity generation, heating, and cooling. It works by tapping into the natural heat that is generated within the Earth's core and can be harnessed through geothermal power plants and direct-use applications. Real-world examples of geothermal energy use include California's Geysers power plant and Iceland's use of geothermal energy for electricity generation. By understanding the basics of geothermal energy and its benefits, we can begin to explore ways to incorporate this renewable energy source into our daily lives.

text: The long period is defined as a period of time which is sufficient to bring about proper changes in the scale of operations through an adjustment of the quantity of the various factors employed. The quantity of all the factors can increase or decreased according to the requirements of production. In the long – run all factors are variable and there is nothing like the fixed cost of production. if the scale of production is to be expanded, new buildings can be hired, new machinery can be installed and the administrative or sale staff can be increased. The size and the organisation of the firm can be altered to adapt the scale of its operations and thus produce the output in the most efficient way. In the technical language, the indivisible factors become divisible in the long – run and therefore they can all be used more economically. The amount of capital can be changed and improvements can be made in the management to look into the problems with greater efficiency.SUBMIT ASSIGNMENT NOW!

Lesson: Understanding the Long-Run in Economics

Introduction:
In economics, the long-run refers to a period of time that is sufficient enough to bring about proper changes in the scale of operations through adjustments in the quantity of various factors employed. In this lesson, we will explore what the long-run means in economics, how it differs from the short-run, and the implications of operating in the long-run.

Section 1: What is the Long-Run?

Topic 1: Definition of the Long-Run
In economics, the long-run is defined as a period of time that is sufficient enough to bring about proper changes in the scale of operations through an adjustment of the quantity of the various factors employed. This means that in the long-run, all factors are variable, and there is nothing like the fixed cost of production.

Topic 2: Differences between the Short-Run and Long-Run
The short-run refers to a period of time where at least one factor of production is fixed, while in the long-run, all factors are variable. In the short-run, firms cannot change the quantity of capital or land they use, but in the long-run, they can adjust the quantity of all factors, including labor, capital, land, and technology.

Section 2: Operating in the Long-Run

Topic 1: Advantages of Operating in the Long-Run
Operating in the long-run has several advantages. Firstly, firms can expand their scale of production without worrying about fixed costs. Secondly, they can improve their management and organization to increase efficiency. Finally, they can make investments in new technology or infrastructure to reduce costs and improve productivity.

Topic 2: Disadvantages of Operating in the Long-Run
While operating in the long-run has many advantages, it also comes with some disadvantages. For example, firms may face uncertainty in the market, making it difficult to predict future demand. Additionally, firms may have to invest significant amounts of capital upfront, which can be risky if the market changes unexpectedly.

Section 3: Examples of Operating in the Long-Run

Example 1: A small bakery decides to expand its production capacity to meet increasing demand for its products. To do this, they invest in new ovens, hire more staff, and purchase additional ingredients. By doing so, they are operating in the long-run because they are adjusting the quantity of all factors of production.

Example 2: A tech company invests in research and development to create a new software program. They hire new engineers, designers, and marketers to work on the project. By doing so, they are operating in the long-run because they are adjusting the quantity of all factors of production.

Conclusion:
In this lesson, we learned about the long-run in economics, how it differs from the short-run, and the implications of operating in the long-run. We explored the advantages and disadvantages of operating in the long-run and provided examples of firms that operate in this manner. By understanding the long-run, we can better appreciate the importance of adjusting the quantity of all factors of production to optimize efficiency and productivity.

Glossary:
Long-Run: A period of time that is sufficient to bring about proper changes in the scale of operations through an adjustment of the quantity of the various factors employed.
Short-Run: A period of time where at least one factor of production is fixed.
Fixed Costs: Costs that do not change with the quantity of output produced.
Variable Costs: Costs that change with the quantity of output produced.
Scale of Production: The amount of goods or services produced by a firm.
Capital: Money or other resources used to produce goods or services.
Land: The natural resources used in production, such as land, water, and minerals.
Technology: The tools, machines, and processes used to produce goods or services.

3. Aluminum - this is a lightweight metal that is often used for building small boats such as rowboats or canoes.
4. Steel - this is a strong material that is often used for building large commercial vessels such as ships or barges.

## Chapter 5: Boat Building Techniques

There are several techniques used in boat building, including:

1. Planking - this involves laying wooden planks on top of a framework to create the hull of the boat.
2. Molding - this involves creating a mold of the boat's hull and laying fiberglass or other materials over it to create a strong, lightweight hull.
3. Welding - this involves joining metal pieces together using heat and pressure to create a strong, sealed joint.
4. Riveting - this involves using rivets to join pieces of metal together, creating a strong, sealed joint.

## Chapter 6: Boat Building Tools

There are several tools used in boat building, including:

1. Saws - these are used to cut wood, metal, or fiberglass to shape the boat's hull and deck.
2. Drills - these are used to create holes in wood, metal, or fiberglass to attach hardware or other components.
3. Sanders - these are used to smooth wood, metal, or fiberglass surfaces to create a smooth finish.
4. Grinders - these are used to grind and polish fiberglass or metal surfaces to create a smooth finish.
5. Measuring tools - these are used to ensure that the boat is built to precise specifications.

## Chapter 7: Boat Building Safety

Safety is a top priority in boat building. This includes ensuring that the boat is built to meet safety standards and that all materials and tools are used safely during construction.

North Dakota Agrees to Court-Ordered Relief Easing Voter ID Laws for Native Americans on Reservations

April 24, 2020

Categories: Civil Rights (Voting Rights, Juries, Census)

On April 24, 2020, the Spirit Lake Nation and Standing Rock Sioux Tribe have filed a binding agreement with the state of North Dakota settling a longstanding fight over voting rights for Native Americans. Once approved by the court, the agreement will be enforceable by court order and will provide essential safeguards to protect Native Americans’ right to vote, easing the financial and logistical burdens that North Dakota’s voter ID law placed on tribes.

The Native American Rights Fund (NARF) and the Campaign Legal Center (CLC) represented the two tribes in the legal challenge, which was consolidated with a separate suit brought by NARF in 2016. The two lawsuits stem from the restrictive voter ID law enacted in 2013. Collectively, the two tribes have over 7,000 residents of voting age that will benefit from the consent decree, which will be in force for the statewide primary election on June 9.

“For the last four years, we have fought hard to protect the voice of Native voters in North Dakota. The ability to vote should never depend on home ownership or whether the government has assigned your home an address,” said NARF Staff Attorney Matthew Campbell. “We are relieved that North Dakota has recognized the need to hear all of its citizens’ voices, and we commend the state for taking these steps to ensure that Native American voters are able participate in the political process.”

“This is a sweeping victory for Native American voting rights, and one that should send a message to other states looking to impose restrictive voting measures that disenfranchise historically marginalized groups,” said Paul Smith, vice president at CLC. “We applaud North Dakota for moving beyond discriminatory schemes and agreeing to provide a meaningful method for Native Americans to verify their residency and protect their constitutional right to vote. In order to have a successful 2020 election, the state must follow through with a robust voter and poll worker education campaign to fully move past their failed addressing system.”

One of its strongest protections in the proposed consent decree is a provision that allows Native American voters who do not have or do not know their residential street address to locate their residence on a map at the polls or when applying for an absentee ballot, be provided with their address by county officials, and have their ballots counted.

North Dakota’s agreement with the two tribes will ensure that tribal IDs and tribally designated street addresses are accepted as valid. It also cements commitments made by state officials in February to seek reimbursement of the tribes’ expenses in producing voter IDs and to coordinate with the Department of Transportation to visit reservations prior to each election to provide access to state-issued IDs at no cost.

Section 1: History of Voting Rights for Native Americans

Native Americans have been fighting for their right to vote since the early days of the United States. In 1851, the U.S. Supreme Court ruled in Dred Scott v. Sandford that Native Americans were not considered citizens and therefore had no right to vote. It wasn't until 1924 that Congress granted all Native Americans U.S. citizenship, which allowed them to vote in federal elections. However, many states still denied Native Americans the right to vote in state and local elections.

Section 2: Challenges Faced by Native Americans When Voting

One of the biggest challenges faced by Native Americans when voting is the lack of access to proper identification. Many Native Americans live on reservations where they may not have easy access to a government office to obtain an ID. Additionally, some reservations do not have street addresses, making it difficult for Native Americans to receive mail, including voter registration forms and absentee ballots.

Section 3: Protecting the Voting Rights of Native Americans

In recent years, several lawsuits have been filed to protect the voting rights of Native Americans. In 2016, the Native American Rights Fund (NARF) and the Campaign Legal Center (CLC) represented the Spirit Lake Nation and Standing Rock Sioux Tribe in a legal challenge against North Dakota's voter ID law. The law required voters to show a valid ID with a street address, which made it difficult for Native Americans living on reservations to vote. The lawsuit argued that the law violated the Constitution and the Voting Rights Act.

On April 24, 2020, the Spirit Lake Nation and Standing Rock Sioux Tribe reached a binding agreement with the state of North Dakota to ease the financial and logistical burdens that the voter ID law placed on tribes. Once approved by the court, the agreement will provide essential safeguards to protect Native Americans' right to vote.

Conclusion:

In conclusion, we have learned about the history of voting rights for Native Americans and the challenges they face when voting. We also learned about the steps taken to protect their rights, such as the lawsuit filed by NARF and CLC. By understanding these issues, we can work towards ensuring that all Americans have equal access to the voting booth.

Lesson: Introduction to Photography

## Section 1: Theoretical Concepts
In this lesson, we will learn about the basics of photography. We will cover the following concepts:

1. What is photography?
2. How does a camera work?
3. What are the different types of photography?

**Question:** What do you think photography means?

**Answer:** Photography refers to the process of capturing light patterns that form visual images. It is an art form that uses light, color, and composition to create aesthetically pleasing images.

**Question:** How does a camera work?

**Answer:** A camera works by capturing light through a lens and converting it into an image. When light enters the camera, it passes through the lens, which focuses the light onto a sensor. The sensor then converts the light into an electrical signal, which is processed into an image by the camera's processor.

**Question:** What are the different types of photography?

**Answer:** There are several types of photography, including portraiture, landscape, wildlife, architecture, sports, fashion, and documentary. Each type of photography has its own unique challenges and techniques.

## Section 2: Practical Examples
Now that we understand the theoretical concepts of photography, let's look at some practical examples. We will explore the following:

1. Composition techniques
2. Lighting techniques
3. Camera settings

**Question:** What are some composition techniques in photography?

**Answer:** Composition techniques refer to the rules or guidelines that help photographers create visually appealing images. Some common composition techniques include the rule of thirds, leading lines, framing, and symmetry.

**Question:** What are some lighting techniques in photography?

**Answer:** Lighting techniques refer to the methods used to control and manipulate light to create the desired mood or effect in an image. Some common lighting techniques include soft lighting, hard lighting, backlighting, and sidelighting.

**Question:** What are some camera settings in photography?

**Answer:** Camera settings refer to the various options available on a camera that can be adjusted to control the exposure, focus, and other technical aspects of an image. Some common camera settings include shutter speed, aperture, ISO, and white balance.

## Section 3: Self-Debating Discussions
In this section, we will engage in self-debating discussions to learn how to critically analyze and improve our photography skills. We will explore the following:

1. How can I improve my composition skills?
2. What are some common mistakes to avoid when taking photographs?
3. How can I develop my own unique style in photography?

**Discussion:** How can I improve my composition skills?

**Answer:** One way to improve your composition skills is to practice using the rule of thirds. This technique involves dividing the frame into nine equal parts and placing the subject or points of interest along the lines or at the intersections. Another way to improve your composition skills is to experiment with different camera angles and perspectives.

**Discussion:** What are some common mistakes to avoid when taking photographs?

**Answer:** Some common mistakes to avoid when taking photographs include having a cluttered background, poor focus, incorrect exposure, and lack of emotion or connection with the subject. To avoid these mistakes, it is essential to master the basic techniques of photography, such as composition, lighting, and camera settings.

**Discussion:** How can I develop my own unique style in photography?

**Answer:** Developing your own unique style in photography requires experimentation, practice, and patience. Start by finding inspiration in other artists' work and identifying what speaks to you. Then, begin experimenting with different techniques, such as using unconventional angles, unique compositions, or specific lighting styles. Over time, your unique style will emerge as you refine your skills and develop your own creative voice.

## Glossary
- Composition: The arrangement of elements in a photograph to create a visually appealing image.

We also explored practical examples, such as composition techniques, lighting techniques, and camera settings. Finally, we engaged in self-debating discussions to learn how to critically analyze and improve our photography skills. By applying these concepts and techniques, we can develop our own unique style in photography and create stunning images that capture the beauty and complexity of the world around us.


text: This application is a revised submission for a 5-year competitive continuation to grant 1R01-DA015269, Gender Identity and HIV Risk. The long-range goal of our research is to reduce HIV transmission among individuals stigmatized for their gender nonconformity and diversity, a goal consistent with the Healthy People 2010 objective to reduce the nation's health disparities. Key findings from our prior work were: a) a national sample of these individuals can be effectively reached via the Internet;b) differences in sex, gender identity/role, and sexual orientation are associated with important differences in HIV risk behavior;c) individuals in the female role are particularly vulnerable to HIV infection through the high risk behavior of the men with whom they interact. We propose to build on these findings by investigating the HIV risk behavior and cofactors of this population's high risk male partners (N=400), using online survey and interview methods successfully applied in the original project (Aim 1). These results will help inform the development of a theory- driven, Internet-based, HIV prevention intervention for individuals who are stigmatized for their gender non- conformity (Aim 2). The intervention will be modeled on an offline HIV intervention shown, in an uncontrolled trial, to reduce risk behavior in the target population. After user-testing and refinement of the prototype online intervention, we will conduct a randomized controlled trial (N=600) to evaluate its efficacy in improving health and reducing HIV risk behavior (Aim 3). This study is innovative in that a) few interventions exist for this minority population and even fewer have been adequately evaluated;b) the intervention will combine HIV prevention and behavior change theories with principles of e-learning;c) the entire study will be implemented online. Our team is highly experienced in HIV prevention research with diverse and vulnerable populations, the benefits/challenges of Internet-based research (online recruitment, data collection, intervention adaptation), and sexual health theory and measures. The project has public health significance in that the minority population targeted for intervention is at high risk for HIV infection, and the men with whom they interact not only pose a risk to them, but also to the general population. If proven effective, the online intervention can be implemented with little additional cost to reduce gender-related HIV risks on a large scale, nationally and internationally, even among highly stigmatized groups.

Lesson: Introduction to Online Surveys and Interview Methods

## Section 1: Theoretical Concepts

Online surveys and interview methods are research techniques used by social scientists to collect data from a large number of people. These methods are particularly useful when studying populations that are difficult to reach through traditional face-to-face interviews.

## Section 2: Practical Examples

Let's say you are conducting a study on the attitudes of college students towards environmental issues. You want to collect data from a large number of students across different campuses. Using online surveys and interview methods, you can create a survey that is distributed through email or social media platforms. Students who receive the survey can complete it at their own pace and from any location.

## Section 3: Real-World Scenarios

A market research company wants to understand the buying habits of a particular demographic group. They use online surveys and interview methods to collect data on the group's purchasing behavior. The company then analyzes the data to identify patterns and trends in the group's spending habits.

## Glossary

**Online Surveys**: A research method where participants complete a questionnaire through the internet.

**Interview Methods**: A research method where participants are interviewed through the internet using video conferencing software or chat applications.

## Conclusion

Online surveys and interview methods are valuable tools for researchers who need to collect data from a large number of people. By understanding the theoretical concepts, applying practical examples, and analyzing real-world scenarios, you can gain a deeper understanding of how these methods are used in research.


text: After missing round 7, I returned to 130R for another exciting day of racing. The series’ first race on the new track layout was sure to be eventful, with close competition.. My dad and I showed up early to do some practice laps with Igor, just trying to remember how to drive the track. Only 9 people showed up, so there was one group of super fast drivers, with Don taking pole, myself second, Igor third and my dad Chris in fourth.. I had a pretty good start to the race, but was nowhere near as quick as Igor was off the line. After following him and Don around for a bit, I went three wide into Turn 9 and made the pass for the lead! I extended my lead at the front of the field, and focused on setting quick laps. As the checkered flag waved, the announcer came on the PA system to announce I’d set a new track record!. -Daniel Demaras.

Lesson: Introduction to Real Estate

### Section 1: What is Real Estate?
Real estate refers to the land and any buildings or other improvements on it. It is a form of property that can be bought, sold, or rented for profit. Real estate can include residential homes, commercial buildings, industrial sites, agricultural land, and more.

### Section 2: Types of Real Estate
There are four main types of real estate: residential, commercial, industrial, and agricultural. Residential real estate includes single-family homes, condos, townhouses, and apartments. Commercial real estate includes office buildings, shopping centers, hotels, and other properties used for business purposes. Industrial real estate includes factories, warehouses, and other properties used for manufacturing or distribution. Agricultural real estate includes farmland and ranches.

### Section 3: How to Invest in Real Estate
There are several ways to invest in real estate, including:

1. Buying rental properties: You can purchase a property and rent it out to tenants, collecting monthly income in the form of rent.

2. Flipping houses: You can buy a property, make improvements to it, and then sell it for a profit.

3. Investing in REITs: Real estate investment trusts (REITs) are companies that own and operate income-producing real estate. By investing in a REIT, you can earn dividends from the rental income generated by the properties in the portfolio.

4. Investing in real estate funds: Real estate funds pool money from multiple investors to purchase a diversified portfolio of real estate assets.

### Section 4: Risks and Rewards of Investing in Real Estate
Investing in real estate can be a lucrative way to build wealth, but it also comes with risks. Some potential risks include:

1. Market fluctuations: Real estate values can rise and fall depending on market conditions. If you buy a property at the wrong time, you could lose money if values decline.

2. Vacancies: If you're renting out a property, there's always the risk that it could remain vacant for an extended period of time, reducing your income.

3. Maintenance and repair costs: Owning a rental property means you're responsible for maintenance and repairs, which can be costly.

However, the rewards of real estate investing can be significant. For example, if you buy a property at a low price and sell it later at a higher price, you'll earn a profit. Additionally, rental income can provide a steady stream of passive income.

### Section 5: Conclusion
Real estate is a complex and dynamic industry, offering numerous opportunities for investment and profit. By understanding the basics of real estate, you can make informed decisions about whether it's the right investment for you. Whether you're interested in buying and holding rental properties, flipping houses, or investing in REITs or real estate funds, there are many ways to get involved in this exciting and potentially lucrative market.

Andreatta: Pagan says chickenpox vaccine is against his religion

Ever since a debunked study linked vaccines to autism nearly 20 years ago, misguided parents have abused religious exemptions to avoid immunizing their school-aged children.

The impact has been a weakened herd immunity and increased risk of disease, like the outbreak of measles that swept California in 2015, leading the state to ban religious exemptions.

If New York were looking for another good reason to follow California’s lead, one could have been found on the porch of a North Goodman Street duplex in Rochester on a recent weekday morning.

More: Debunking vaccine myths

More: Chickenpox vaccination, other vaccines have saved nearly $1 billion

There sat Joseph O’Neill and his 9-year-old daughter, Lilith. Most children Lilith’s age would have been in school, which is where she and her father said they would have liked her to be.

But Lilith hasn’t been in school since last November, when the Rochester City School District rejected O’Neill’s objection to her receiving the chickenpox vaccine on religious grounds.

O’Neill, 42, considers himself a Norse pagan. He wears his hair long and has the Norse runes, an ancient Germanic alphabet, tattooed on his left forearm. A silver Mjolnir, the fearsome hammer of Thor, dangles from a chain around his neck.

He may be a pagan, he said, but he’s also a realist, which is why he had Lilith get all the other immunizations required by New York.

“If it’s a matter of life or death, then yeah,” O’Neill said. “But chickenpox? When’s the last time you heard of someone dying of chickenpox?”

Chickenpox is rare today. But when O’Neill was a kid, there were 4 million cases in the United States a year, and only about 100 deaths, according to the Centers for Disease Control.

He said his religion calls for natural remedies to illness when possible. Because so few people die of chickenpox, he said, a vaccine for it runs contrary to his religious beliefs.

“The school district is denying my daughter an education based on our religious beliefs,” O’Neill said.

That’s a matter of debate. State law demands schoolchildren be immunized unless they have a medical or religious exemption.

This isn’t a matter of debate: New York is one of 47 states that allow religious exemptions to required immunizations, and what constitutes an exemption is hazy.

Under state law, parents claiming a religious exemption don’t have to prove their faith opposes vaccines, but must provide a written explanation of a “genuine and sincere” religious objection. School officials can accept or reject the explanation.

When nurses at Lilith’s school, School 20, discovered she had not had the varicella vaccine for chickenpox, district officials demanded she get inoculated or claim an exemption.

O’Neill submitted a form letter he found online that read in part, “the practice of vaccination is contrary to our beliefs and would violate our religious principles.” The letter never mentioned Norse paganism or natural remedies.

He recalled that the principal found his explanation adequate. A district lawyer disagreed.

“I have reviewed your request and have determined that it is insufficient to demonstrate that you have sincere and genuine religious beliefs which would support a religious exemption from immunization,” the lawyer wrote him in a letter dated Nov. 10.

Six days later, Lilith was kicked out of school. O’Neill has homeschooled her ever since.

“Who is the school system to say that my beliefs aren’t sincere?” O’Neill asked.

Since O’Neill asked, a school district is no one to judge his beliefs or anyone else’s. But this is what happens when the law empowers public schools to weigh in on matters of faith.

A better question is why the law allows religious exemptions at all.

The First Amendment guarantees one’s right to practice any religion, but its Establishment Clause separates church from state. The latter goes for public schools.

RCSD spokesman Don Starver denied that the district lawyer judged O’Neill’s religion.

“He never said what his religion was, or why his religion opposes (the vaccine),” Starver said. “All you have to do is explain to us what the religion is and what your objection is. … The criterion is pretty loose.”

Allowing religious exemptions puts children at risk and school officials in an awkward spot of deciding which pleas for exemptions are legitimate and which are bogus, usually with no knowledge of the religion held by parents seeking relief.

Religion aside, the science on vaccines is clear: They’re safe and effective. Protecting the health of children trumps religious beliefs guaranteed by the Constitution. That’s why the U.S. Supreme Court has upheld compulsory vaccination laws.

Buy O’Neill’s religious exemption or not. The law simultaneously offers him a loophole and allows school officials to pass judgment on the sincerity of his convictions.

Religion has no place in public schools or matters of public health. Get rid of the exemption.

Lesson: The Importance of Vaccinations

Introduction:
Vaccinations are an important part of public health and have significantly reduced the spread of diseases that were once common and deadly. However, there are some people who choose not to vaccinate their children based on misinformation and personal beliefs. In this lesson, we will explore the importance of vaccinations and why they are necessary for public health.

Section 1: Understanding Vaccinations

Topic 1: What are vaccinations?
Vaccinations are a type of preventive medicine that help protect people from certain diseases. They work by introducing a small, safe piece of the virus or bacteria that causes the disease into the body. This stimulates the immune system to produce a defense against the disease, without causing the disease itself.

Topic 2: How do vaccinations work?
When a person receives a vaccination, their immune system produces cells called lymphocytes and antibodies that are specific to the disease. These cells and antibodies stay in the body and provide long-lasting immunity against the disease. If the person is exposed to the disease in the future, their immune system can recognize it and fight it off quickly, preventing illness.

Section 2: The Benefits of Vaccinations

Topic 1: Herd Immunity
Herd immunity occurs when a large percentage of the population is immune to a disease, either through vaccination or previous infection. This prevents the spread of the disease to those who are not immune. When enough people are vaccinated, it becomes difficult for the disease to spread, protecting even those who cannot be vaccinated due to medical reasons.

Topic 2: Economic Benefits
Vaccinations save money by preventing illness and reducing the need for medical care. They also reduce the number of missed school and work days due to illness. In addition, vaccinations have been shown to be cost-effective compared to the costs of treating diseases.

Section 3: Debunking Myths About Vaccinations

Myth 1: Vaccines cause autism
This myth was started by a debunked study published in 1998 that suggested there was a link between the MMR (measles, mumps, and rubella) vaccine and autism. Since then, numerous studies have been conducted, and none have found any link between vaccines and autism.

Myth 2: Natural immunity is better than vaccine-induced immunity
While it is true that getting sick and recovering from a disease can provide some immunity, this is not always the case. Some diseases provide lifelong immunity, while others may only provide temporary immunity. Vaccinations provide long-lasting, reliable immunity without the risk of severe illness.

Conclusion:
Vaccinations are an important part of public health and have significantly reduced the spread of many diseases. They are safe and effective, and provide long-lasting immunity. By vaccinating our children, we are protecting not only them but also our community as a whole. We hope that this lesson has provided you with a better understanding of the importance of vaccinations.

Glossary:
- Vaccination: A type of preventive medicine that helps protect people from certain diseases.
- Lymphocyte: A type of white blood cell that plays a role in the immune system.
- Antibody: A protein produced by the immune system in response to a foreign substance, such as a virus or bacteria.
- Herd immunity: Occurs when a large percentage of the population is immune to a disease, preventing its spread to those who are not immune.
- Immune system: The body's defense against infections and diseases.

The manipulation of C60 in molecular arrays with an STM tip in regimes below the decomposition threshold.
The ability of scanning tunneling microscopy to manipulate selected C(60) molecules within close packed C(60) arrays on a (Au,In)/Si(111) surface has been examined for mild conditions below the decomposition threshold. It has been found that knockout of the chosen C(60) molecule (i.e., vacancy formation) and shifting of the C(60) molecule to the neighboring vacant site (if available) can be conducted for wide ranges of bias voltages (from -1.5 to +0.5 V), characteristic manipulation currents (from 0.02 to 100 nA) and powers (from 2 × 10(-8) to 0.1 μW). This result implies that the manipulation is not associated with the electrical effects but rather has a purely mechanical origin. The main requirement for successful C(60) knockout has been found to be to ensure a proper 'impact parameter' (deviation from central impact on the C(60) sphere by the tip apex), which should be less than ~1.5 Å. A certain difference has been detected for the manipulation of C(60) in extended molecular arrays and molecular islands of a limited size. While it is possible to manipulate a single C(60) molecule in an array, in the case of a C(60) island it appears difficult to manipulate a given fullerene without affecting the other ones constituting the island.

Lesson Title: Scanning Tunneling Microscopy (STM) and Molecular Manipulation

Introduction:
Scanning tunneling microscopy (STM) is a powerful tool used to study the surface properties of materials at the atomic level. In this lesson, we will learn about how STM can be used to manipulate molecules, specifically C60, in molecular arrays.

Section 1: Theory
- STM works by bringing a sharp tip close to the surface of a material, which allows electrons to tunnel between the tip and the surface.
- By measuring the tunneling current, STM can create an image of the surface with atomic resolution.
- STM can also be used to manipulate molecules by applying a voltage to the tip, which can cause the molecules to move or even break apart.

Section 2: Practice
- Question: How does STM work?
- Answer: STM works by measuring the tunneling current between a sharp tip and the surface of a material. When the tip is brought close enough to the surface, electrons can tunnel through the gap between them, creating an image of the surface with atomic resolution.
- Question: How can STM be used to manipulate molecules?
- Answer: STM can be used to manipulate molecules by applying a voltage to the tip. This can cause the molecules to move or even break apart, depending on the voltage and other factors.
- Question: What are some examples of molecules that can be manipulated using STM?
- Answer: One example is C60, which is a fullerene molecule composed of carbon atoms arranged in a spherical structure. Other molecules can also be manipulated using STM, depending on the specific experimental setup and conditions.

Section 3: Real-World Examples
- STM has been used to study the properties of various materials, including graphene, nanoparticles, and biological systems.
- In one experiment, researchers used STM to manipulate C60 molecules in molecular arrays on a gold and indium surface. They found that they could knock out a chosen C60 molecule (i.e., vacancy formation) and shift the C60 molecule to the neighboring vacant site, depending on the voltage and other factors.
- This ability to manipulate molecules using STM has important implications for fields such as nanotechnology, materials science, and chemistry.

Glossary:
- STM: Scanning tunneling microscopy
- C60: A fullerene molecule composed of carbon atoms arranged in a spherical structure
- Molecular array: A arrangement of multiple molecules in a regular pattern
- Decomposition threshold: The point at which a substance begins to break down or decompose
- Impact parameter: The distance between the tip apex and the center of the C60 sphere

Conclusion:
In this lesson, we learned about how STM can be used to manipulate molecules, specifically C60, in molecular arrays. We covered the theory behind STM, practical examples of molecular manipulation, and real-world applications of this technology. By understanding the principles of STM and its potential for molecular manipulation, we can apply these skills to new problems and continue to explore the fascinating world of nanoscale science and engineering.

Introduction:
Catalysts are substances that increase the rate of chemical reactions without being consumed in the process. They play a crucial role in various industrial processes, including environmental protection. In this lesson, we will learn about the importance of catalysts in removing pollutants from the environment, specifically nitrogen oxides (NOx) in the case of ammonia-selective catalytic reduction (NH3-SCR).

Section 1: What are Catalysts and their Applications?
Topic 1.1: Definition of Catalysts
A catalyst is a substance that increases the rate of a chemical reaction by lowering the activation energy required for the reaction to occur. It does not change the overall energy balance of the system but speeds up the reaction by providing an alternative reaction pathway.

Topic 1.2: Importance of Catalysts in Environmental Protection
Catalysts are essential in environmental protection because they help reduce pollution levels by breaking down pollutants into harmless substances. For example, in the case of NH3-SCR, catalysts help convert NOx into nitrogen (N2) and water (H2O), reducing air pollution.

Topic 1.3: Types of Catalysts
Catalysts can be classified into several categories based on their properties and applications. These include:

1. Homogeneous catalysts: These are catalysts that exist in the same phase as the reactants (e.g., liquid or gas).
2. Heterogeneous catalysts: These are catalysts that exist in a different phase than the reactants (e.g., solid catalysts in a gaseous reaction).
3. Enzymatic catalysts: These are biological catalysts that speed up chemical reactions in living organisms.

Section 2: Preparation and Characterization of Cu0.02Fe0.2CeyTi1-yOx Catalysts
Topic 2.1: Sol-Gel Method
The sol-gel method is a technique used to prepare solid materials from colloidal suspensions. It involves the formation of a gel network followed by drying and calcination to form a solid material.

Topic 2.2: Synthesis of Cu0.02Fe0.2CeyTi1-yOx Catalysts
Cu0.02Fe0.2CeyTi1-yOx catalysts were synthesized using the sol-gel method. The composition of the catalysts was controlled by varying the concentration of cerium (y).

Topic 2.3: Characterization Techniques
Various characterization techniques were used to study the physical and chemical properties of the synthesized catalysts. These included:

1. X-ray diffraction (XRD): To determine the crystal structure of the catalysts.
2. Brunauer-Emmett-Teller (BET) analysis: To measure the surface area of the catalysts.
3. Temperature-programmed desorption (TPD) and temperature-programmed reduction (TPR): To study the surface chemistry and redox properties of the catalysts.

Section 3: Low-Temperature NH3-SCR Performance and Water Resistance of Cu0.02Fe0.2CeyTi1-yOx Catalysts
Topic 3.1: Low-Temperature NH3-SCR Performance
The performance of the synthesized catalysts was tested in an NH3-SCR reaction at low temperatures. The results showed that Cu0.02Fe0.2Ce0.2Ti0.8Ox had the best performance, with high conversion rates of NOx and low activation temperatures.

Topic 3.2: Water Resistance
The water resistance of the synthesized catalysts was also tested in an NH3-SCR reaction in the presence of water. The results showed that Cu0.02Fe0.2TiOx had poor water resistance, while Cu0.02Fe0·2Ce0·2Ti0.8Ox exhibited excellent water resistance.

Section 4: Conclusion
In conclusion, the synthesis and characterization of Cu0.02Fe0.2CeyTi1-yOx catalysts have shown promising results in terms of low-temperature NH3-SCR performance and water resistance. The addition of cerium to the catalysts improved their surface acidity and oxygen content, leading to better performance. This research highlights the importance of catalysts in environmental protection and the potential for further research in this field.

Lesson: Understanding College Baseball Draft Prospects

## Introduction

The Major League Baseball (MLB) Draft is an annual event where professional baseball teams select amateur players who are eligible to sign contracts. In this lesson, we will learn about mid-major college baseball draft prospects and how they are evaluated by scouts.

## Section 1: Understanding the College Baseball Draft

The MLB Draft takes place every year in June. It consists of 40 rounds, during which teams select players from high schools, colleges, and other amateur organizations. The first round is broadcast live on national television, and the rest of the rounds take place over the course of several days.

College baseball players are eligible for the draft if they have completed their junior year or are at least 18 years old. However, they can choose to return to college for another year before entering the draft again. This is known as "going back to school."

## Section 2: Evaluating Draft Prospects

Scouts evaluate draft prospects based on several factors, including:

1. Physical abilities: Scouts look for players with good size, speed, and strength. They also evaluate a player's overall athleticism and how it translates to the baseball field.

2. Baseball skills: Scouts watch players hit, pitch, and field to assess their skill level. They look for players who have good mechanics, make consistent contact, and can throw strikes.

3. Intangibles: Scouts also consider a player's mental makeup, work ethic, and leadership skills. They want to see players who are coachable, competitive, and have a strong desire to improve.

## Section 3: Mid-Major Draft Prospects

Mid-major college baseball programs are those that are not associated with major conferences or well-known universities. Despite this, many mid-major programs produce talented draft prospects each year. Some of these prospects include:

1. Collin Baumgartner, RHP, SIU-Edwardsville: Baumgartner is a 6-foot-6, 240-pound pitcher who has shown good arm strength and a low-80s slider with occasional late bite.

2. TT Bowens, OF, Central Connecticut: Bowens is a speedy outfielder who has shown the ability to steal bases and hit for power.

3. Joe Gillette, RHP, Bucknell: Gillette is a tall, projectable pitcher who has shown good command of his fastball and curveball.

## Section 4: Conclusion

Understanding college baseball draft prospects is an important part of evaluating talent in the sport. By learning about mid-major prospects, we can gain insight into the types of players who may be available for selection in the upcoming draft. As we continue to study baseball and follow the draft, we will be better equipped to understand the process and its implications for the future of the game.

1. Field of the Invention
This invention relates to internal combustion engines, and more specifically to thermally regenerated internal combustion engines.
2. Description of Prior Art
Conventional Otto and Diesel cycle piston engines operate by intaking fresh air, compressing the air, burning fuel with the air to produce high temperature, high pressure combustion products, expanding the combustion products to convert part of the heat into work, and then exhausting the spent gases. These engine cycles are relatively inefficient in converting heat into work because of the practical limitations on the extent of the compression and expansion processes. In order to operate at the highest efficiency which is theoretically possible, the hot product gases would need to be expanded until they had cooled to room temperature. However, with the thermal properties of ordinary combustion products, this would require an expansion volume ratio in excess of one thousand. Those skilled in the art will be aware that an engine with a volume expansion ratio of one thousand and a final gas pressure at or near atmospheric would require a peak pressure so high as to threaten destruction of cylinder, piston and other moving parts, and would aggravate losses from friction, heat transfer, and gas leakage.
In the past, attempts have been made to recover the residual heat energy in the exhaust gas from internal combustion engines by passing the gas through a gas turbine, but such turbines have pressure ratios far too low to convert much of the exhaust heat into work. Internal combustion engine exhaust gases have also been used as the heat source for a Rankine (steam engine) bottoming cycle, but this introduces undesirable complexity, cost and size into the engine design.
A very promising technique for substantially increasing the thermal efficiency of an internal combustion piston engine is through thermal regeneration. Thermal regeneration, as used herein, implies the capture of exhaust gas heat from one engine cycle and the transfer of this heat to the working fluid of the subsequent cycle following its compression, but prior to the combustion of the fuel, so as to reduce the required quantity of fuel to be burned. A number of attempts have been made to devise means by which regenerative features similar to those employed in a Stirling or Ericsson type engine could be used to accomplish this. Most notable of these techniques are those of Hirsch (1874, U.S. Pat. No. 155,087), Martinka (1937, U.S. Pat. No. 2,239,922), Pattas (1973, U.S. Pat. No. 3,777,718), Bland (1975, U.S. Pat. No. 3,871,179), Pfefferle (1975, U.S. Pat. No. 3,923,011), Cowans (1977, U.S. Pat. No. 4,004,421), and Stockton (1978, U.S. Pat. No. 4,074,533).
The Hirsch, Martinka, Pattas and Stockton engines all employ multiple cylinders and pistons for each working unit to accomplish the regenerative engine cycle. The Cowans engine uses a single cylinder shared by the working piston and a displacer, but uses an external regenerator. All of these prior art techniques involve great mechanical complexity in the form of additional valves, pistons, heat exchangers or regenerators, flow passages, mechanical linkages, etc. In the cases of Hirsch, Pattas, and Cowans, the mechanical features of the engines preclude a compression ratio high enough to develop adequate specific power output from a normally aspirated engine. For this reason, the engines of Hirsch, Martinka, and Cowans were designed to be run at an elevated mean pressure, which requires external compressors to compress the inlet air. The Pattas engine, and the two-piston version of the Stockton engine require external blowers to scavenge the exhaust and provide fresh air for combustion.
Analyses of regenerative engine cycles show that the idealized thermodynamic thermal efficiency increases when the compression ratio is decreased, however the cycle mean effective pressure and specific power output decreases as the compression ratio is decreased. Since an engine with low cycle effective pressure must be larger for a given power output, and since heat conduction losses and friction losses increase with engine size, an optimum design must have an intermediate value for compression ratio, i.e. it must be low enough to give acceptable thermodynamic efficiency, but high enough to give low heat conduction and friction losses. For most applications a compression ratio between four and eight appears to be the best compromise. The Hirsch, Pattas, and Cowans engines are incapable of attaining a compression ratio high enough to fall within the optimum range. The reason that these prior art engines cannot attain sufficiently high compression ratios is that non-optimum, near-sinusoidal motions were employed for the displacers (or for second pistons in two-piston type engines) and in all cases the regenerator was in a fixed position relative to the power piston. In engines of the Hirsch and Pattas types, for instance, the pistons undergo sinusoidal motions with approximately a ninety degree phase difference, and the piston motions cannot overlap since they are separated by a fixed regenerator. In this situation, simple geometric arguments show that the maximum volume ratio cannot be greater than about six, even with a regenerator of zero volume, and if real hardware limitations are taken into account, the resulting compression ratio is far below the optimum value.
The engine disclosed herein uses a basic working unit which consists of a single cylinder and piston and a thin, movable, permeable regenerator which can be swept axially through the working fluid in the space above the piston, and whose motion can overlap the motion of the piston. This is much simpler than any of the prior art engines. The thinness of the regenerator, and the possibility of having the regenerator motions overlap the piston motions makes it possible to have a higher compression ratio than the prior art engines. The regenerator of the disclosed engine is moved by a mechanism such as a cam which can produce the non-sinusoidal regenerator motions which are required to approach the thermodynamically optimum sequence of events. The use of optimum regenerator motions can increase the specific power output of the engine by as much as a factor of five compared to an engine which uses only sinusoidal piston or displacer motions. In contrast to the prior art engines, certain embodiments of the engine herein disclosed can intake air and exhaust spent gases without requiring any assistance from a blower or supercharger. Supercharging may be used with the disclosed engine in order to increase power output, or to provide a lower regenerator cold end temperature, or for other reasons, but it is not necessarily required. The features of the disclosed engine result in a specific power output which is much higher than prior art regenerated internal combustion engines, this in turn permits the use of a smaller engine for a given power output, which results in friction and conduction heat losses which are much lower than in prior art engines.
To summarize, the advantages of the disclosed engine relative to prior art engines include its mechanical simplicity, its high thermal efficiency and power output, its ability to operate without auxiliary superchargers or blowers, and the close similarity of many of the disclosed engine components to those of existing diesel or gasoline engine technology.

Lesson: Understanding Thermodynamics in Internal Combustion Engines

Introduction:
In this lesson, we will learn about thermodynamics in internal combustion engines. We will cover the basic principles of thermodynamics, how they apply to engines, and how engineers use these principles to design more efficient engines.

Section 1: Basic Principles of Thermodynamics
Thermodynamics is the study of energy and how it is transferred between objects. Internal combustion engines work by burning fuel to create heat, which is then converted into mechanical work. The basic principles of thermodynamics that apply to engines are:

1. Energy cannot be created or destroyed, only transferred or transformed.
2. Heat will always flow from hotter to cooler objects.
3. Work is done when an object moves or changes shape due to a transfer of energy.

Section 2: Applying Thermodynamics to Internal Combustion Engines
Internal combustion engines work by using the heat generated from burning fuel to create movement. The four strokes of an engine cycle are:

1. Intake: Fresh air is drawn into the engine.
2. Compression: The air is compressed, creating heat.
3. Power: The fuel is ignited, creating a small explosion that pushes the piston down, turning the crankshaft and creating work.
4. Exhaust: The spent gases are expelled from the engine.

The efficiency of an engine is determined by how much of the energy stored in the fuel is converted into useful work. This is known as the brake thermal efficiency. The higher the efficiency, the more of the energy is used to move the car, and the less is wasted as heat.

Section 3: Designing Efficient Engines
Engineers use the principles of thermodynamics to design more efficient engines. Some ways they do this include:

1. Cooling the air and fuel before they enter the engine. This reduces the amount of heat waste and increases the efficiency.
2. Using turbochargers or superchargers to force more air into the engine, increasing the amount of oxygen available for combustion and improving efficiency.
3. Optimizing the shape and size of the engine components to reduce heat loss and increase efficiency.

Conclusion:
Understanding the principles of thermodynamics is essential for designing efficient internal combustion engines. By applying these principles, engineers can create engines that convert more of the energy stored in fuel into useful work, reducing emissions and improving performance.
