Lesson: Introduction to Acid Rock Drainage (ARD)

## Section 1: What is Acid Rock Drainage (ARD)?
Acid Rock Drainage (ARD) is the outflow of acidic water from metal/coal mines or other areas where rocks containing sulfides are exposed to air and water. ARD occurs when sulfide minerals such as pyrite (FeS2) react with oxygen and water to form sulfuric acid (H2SO4) and dissolved metal ions. This process is known as acid generation.

## Section 2: Why is ARD a problem?
ARD is a significant environmental issue because it can contaminate surface waters and groundwater, harm aquatic life, and pose health risks to humans. ARD can also cause corrosion of pipes and infrastructure, leading to costly repairs.

## Section 3: How can ARD be prevented or mitigated?
There are several ways to prevent or mitigate ARD, including:
- Proper mine planning and design to minimize the exposure of sulfide minerals to air and water
- Use of liners and covers to reduce water infiltration and oxygen exposure
- Treatment of waste rock and tailings to remove sulfides before they are discharged into the environment
- Use of neutralization agents to raise the pH of acidic water before it is released
- Monitoring and maintenance of drainage systems to ensure they are functioning properly

## Section 4: What is the Global Acid Rock Drainage (GARD) Guide?
The GARD Guide is an online resource developed by the International Network for Acid Prevention (INAP) that provides information on the prevention and mitigation of ARD. The Guide includes best practices, case studies, and technical guidance on various aspects of ARD management.

## Section 5: Who can use the GARD Guide?
The GARD Guide is intended for anyone involved in the mining industry, including mine operators, engineers, geologists, and regulators. It is also useful for environmental professionals, researchers, and students interested in learning about ARD and its management.

## Conclusion:
In conclusion, understanding ARD and its management is crucial for protecting the environment and human health. The GARD Guide provides valuable information and resources for anyone involved in the mining industry or interested in learning about ARD. By applying the principles and techniques outlined in the Guide, we can work towards reducing the impacts of ARD and promoting sustainable mining practices.

Lesson: The Importance of Perseverance

Introduction:
Perseverance is the ability to persist in the face of challenges and setbacks. It is an essential quality for success in any field, including science, technology, engineering, and mathematics (STEM). In this lesson, we will explore the importance of perseverance in STEM fields and learn how to develop this quality in ourselves.

Section 1: The Importance of Perseverance in STEM Fields

Topic 1: Science
In science, perseverance is crucial because it allows scientists to keep experimenting until they find the answer they are looking for. Scientists often face many failures before they discover something new. For example, Thomas Edison failed thousands of times before he invented the lightbulb. If he had given up after his first few failures, we would not have the many benefits of electric light today.

Topic 2: Technology
In technology, perseverance is necessary for overcoming obstacles and finding solutions to complex problems. Engineers and computer scientists must be willing to work hard and try different approaches to create new technologies that solve real-world problems. For instance, creating a new software program requires patience and persistence as developers test and refine their code to make it work correctly.

Topic 3: Engineering
Engineers must persevere through challenges to design and build structures, machines, and systems that function safely and efficiently. They must be willing to revise their designs and try again if their initial attempts do not work. For example, building a bridge requires extensive testing and analysis to ensure it can withstand the forces it will experience.

Topic 4: Mathematics
Mathematicians also need perseverance to solve complex problems and prove theorems. They must be willing to think creatively and try different approaches to arrive at a solution. For example, solving a difficult equation may require multiple steps and a willingness to try different methods until the correct one is found.

Section 2: Developing Perseverance

Topic 1: Set Goals
To develop perseverance, it is essential to set clear and achievable goals. This provides a sense of direction and motivation to keep working towards them. For example, a student studying for an exam can set specific goals such as completing a certain number of practice problems each day.

Topic 2: Learn from Failure
Failing is a natural part of learning and growing. Instead of giving up after a setback, use it as an opportunity to learn and improve. For example, if a student fails a test, they can analyze their mistakes and develop strategies to avoid them in the future.

Topic 3: Practice Persistence
Persistence is a skill that can be developed through practice. Start with small tasks and gradually increase the difficulty. For example, a student can start with simple math problems and work their way up to more complex ones.

Section 3: Real-World Examples

Topic 1: The Space Race
The space race between the United States and the Soviet Union in the 1960s required immense perseverance from both sides. Despite setbacks and tragedies, such as the Apollo 1 fire and the Challenger explosion, both countries continued to work towards their goal of landing astronauts on the moon.

Topic 2: The Development of the Internet
The development of the internet required decades of perseverance from many individuals and organizations. Despite numerous technical challenges and setbacks, researchers and engineers continued to work together to create the global network we know today.

Conclusion:
In conclusion, perseverance is a crucial quality for success in STEM fields. By setting goals, learning from failure, and practicing persistence, we can develop this quality and apply it to our studies and careers. As we face challenges and setbacks, let us remember the examples of Edison, the space race, and the development of the internet, and keep pushing forward towards our goals.

Lesson: Real Estate Investment
Introduction:
Real estate investment is the process of purchasing property with the intention of earning a profit from its sale or rental. This can be done through various strategies such as flipping houses, renting out properties, or holding onto land for future development. In this lesson, we will explore the basics of real estate investment and how to identify profitable opportunities.
Section 1: Understanding Real Estate Investment
Topic 1: Types of Real Estate Investments
There are several types of real estate investments, including residential, commercial, industrial, and land. Each type has its own unique characteristics and risks.
Topic 2: How to Identify Profitable Opportunities
To identify profitable real estate investment opportunities, you need to consider several factors such as location, market demand, and potential returns. You also need to analyze the property's current market value and future potential.
Topic 3: Risk Management
Real estate investment involves risk, but there are ways to manage it. One way is to diversify your portfolio by investing in different types of properties and locations. Another way is to use leverage, which means borrowing money to invest in property. However, this also increases your risk if the property value decreases.
Section 2: Analyzing Real Estate Investment Opportunities
Topic 1: Calculating ROI
Return on investment (ROI) is a measure of how much profit you make on an investment. To calculate ROI, you need to subtract the initial cost of the investment from the final selling price and divide the difference by the initial cost.
Topic 2: Cash Flow Analysis
Cash flow analysis is a tool used to determine whether a property will generate positive cash flow, which means you will receive more income from the property than you spend on expenses. To perform a cash flow analysis, you need to know the property's projected income and expenses.
Topic 3: Comparative Market Analysis
A comparative market analysis (CMA) is a tool used to compare similar properties in the same area. It helps you determine the property's market value and potential returns. To perform a CMA, you need to gather data on similar properties and analyze their features, location, and price.
Section 3: Real Estate Investment Strategies
Topic 1: Flipping Houses
Flipping houses involves buying a property, renovating it, and selling it for a profit. To be successful at flipping houses, you need to have a good eye for property values, be able to estimate renovation costs accurately, and have a network of contacts in the construction industry.
Topic 2: Buy and Hold
Buy and hold is a strategy where you purchase a property and hold onto it for a long period of time, earning rental income and waiting for the property value to appreciate. To be successful at buy and hold, you need to have a long-term perspective, be able to manage tenants effectively, and have a solid understanding of the local rental market.
Topic 3: Land Banking
Land banking involves purchasing land and holding onto it until its value appreciates. To be successful at land banking, you need to have a good eye for land values, be able to identify up-and-coming areas, and have patience since land values can take a long time to appreciate.
Conclusion:
Real estate investment can be a lucrative way to build wealth, but it requires careful analysis, risk management, and a solid understanding of the market. By following the strategies outlined in this lesson, you can identify profitable opportunities and build a successful real estate investment portfolio.

Lesson: Introduction to Epidemiology and Control of Emerging Viral Infections in Swine

## Section 1: Theoretical Concepts
Epidemiology is the study of the distribution and control of diseases in populations. In swine production, emerging viral infections can cause significant economic losses and pose a threat to animal welfare. Understanding the factors that contribute to the spread of these infections is crucial for implementing effective control measures.

Control measures may include vaccination regimens, biosecurity protocols, and monitoring the movement of animals and personnel within and between farms. Vaccines are an essential tool in preventing the spread of infectious diseases, including those caused by emerging viruses. However, vaccination strategies must be tailored to the specific needs of each herd and may require adjustments as new viral strains emerge.

## Section 2: Practical Examples
Let's consider a hypothetical scenario where a new viral infection has been detected in a swine herd. The first step in controlling the spread of the disease would be to conduct an epidemiological investigation to determine the source of the infection and identify any risk factors. This may involve collecting data on the herd's management practices, veterinary history, and environmental conditions.

Once the potential sources of the infection have been identified, appropriate control measures can be implemented. For example, if the investigation reveals that the infection was introduced through the movement of personnel between farms, strict biosecurity protocols may be put in place to limit the movement of people and equipment. If the infection was linked to a particular feed supplement, the supplier may be asked to provide alternative feed sources until the issue is resolved.

## Section 3: Self-Debating Discussions
1. What are some common risk factors for the emergence of viral infections in swine herds?
2. How does the movement of animals and personnel contribute to the spread of infectious diseases?
3. What are some practical steps that can be taken to implement effective control measures against emerging viral infections in swine herds?

## Glossary
- Epidemiology: The study of the distribution and control of diseases in populations
- Biosecurity: Measures taken to prevent the introduction and spread of infectious diseases
- Vaccination: The process of administering a vaccine to an individual to stimulate their immune system to protect against a specific infectious disease
- Emerging viruses: New or recently discovered viruses that have the potential to cause disease in humans or animals

## Conclusion
Understanding the principles of epidemiology and control of emerging viral infections in swine herds is essential for maintaining animal health and productivity. By applying the concepts learned in this lesson, students will be better equipped to identify potential risks and implement effective control measures in real-world scenarios.

text:
BANJA LUKA, Bosnia and Herzegovina — Milorad Dodik would like to make two things clear at the outset: that he is the president of a legitimate state, rather than an ethnically cleansed territory in a country with internationally recognized borders; and that, at 58, he can still shoot hoops like a pro.

On basketball, he has a point. He plays regularly, and although he never played professionally outside the former Yugoslavia, once an international powerhouse in the sport, he showed good game on a court in St. Petersburg last summer when he joined a veterans’ team, led by the Russian former NBA star Andrei Kirilenko, against Moscow old-timers.

He is wrong on the presidency, though. Despite his determination to break from the Muslim-Croat part of Bosnia and Herzegovina, Mr. Dodik remains the president of the Serb autonomous region, a slice of territory nearly the size of Belgium. The region likes to call itself the Republika Srpska — a name given to the blood-soaked land by Mr. Dodik’s predecessor, Radovan Karadzic, the convicted war criminal serving a 40-year sentence for genocide against Bosnia’s Muslims.

During his two terms as president of the Republika Srpska — and two more as prime minister — Mr. Dodik has ruffled more than a few feathers. Despite warnings from the international community, and in violation of a ruling from Bosnia’s highest court, he pressed for a referendum in 2016 on whether to celebrate Jan 9 as a national holiday, the day in 1992 Mr. Karadzic declared a Serb-only state in Bosnia, unleashing a genocidal war.

Lesson: The Importance of Critical Thinking in Understanding Complex Situations

Introduction:
In today's fast-paced world, it is essential to develop critical thinking skills to understand complex situations. Critical thinking involves analyzing information, evaluating arguments, and making informed decisions based on evidence. This lesson will teach you how to apply critical thinking skills to a real-world scenario.

Section 1: Understanding the Situation
The scenario we will analyze is the political situation in Bosnia and Herzegovina. We will focus on the Serb autonomous region, which is trying to break away from the rest of the country.

Question: Why does Milorad Dodik want to break away from the Muslim-Croat part of Bosnia and Herzegovina?

Answer: Mr. Dodik wants to create a separate state called the Republika Srpska, which was the name given to the blood-soaked land by his predecessor, Radovan Karadzic, who is serving a 40-year sentence for genocide against Bosnia's Muslims.

Section 2: Analyzing the Information
We know that Mr. Dodik plays basketball regularly and is proud of his skills. However, he also claims that the Republika Srpska is a legitimate state, not just a part of Bosnia and Herzegovina.

Question: How can we evaluate Mr. Dodik's claims?

Answer: To evaluate Mr. Dodik's claims, we need to look at the historical and legal context of the situation. The Republika Srpska was created during the Bosnian War in the 1990s, and its creation was not recognized by the international community. Additionally, Mr. Dodik's predecessor, Radovan Karadzic, was convicted of genocide against Bosnia's Muslims, which casts doubt on the legitimacy of the Republika Srpska.

Section 3: Evaluating the Arguments
Now that we have analyzed the information, we can evaluate Mr. Dodik's arguments.

Question: Are Mr. Dodik's claims about the Republika Srpska legitimate?

Answer: Based on the historical and legal context, it is difficult to consider the Republika Srpska a legitimate state. The international community did not recognize its creation, and its leader, Radovan Karadzic, was convicted of genocide against Bosnia's Muslims. Therefore, Mr. Dodik's claims lack credibility.

Conclusion:
This lesson demonstrates the importance of critical thinking in understanding complex situations. By analyzing information, evaluating arguments, and making informed decisions based on evidence, we can reach conclusions that are grounded in reality. As you continue to learn and grow, remember to apply critical thinking skills to all aspects of your life.

Glossary:
- Critical thinking: the process of analyzing information, evaluating arguments, and making informed decisions based on evidence
- Legitimate: having a right to exist or be considered valid
- Genocide: the deliberate and systematic destruction of a group of people based on their race, religion, or nationality.

Lesson: The Science of Transplantation

Introduction:
Transplantation is the process of transferring an organ or tissue from one body to another. This medical procedure has been used for centuries to treat various diseases and injuries. In this lesson, we will explore the science behind transplantation, including the history, techniques, and challenges associated with this field.

Section 1: History of Transplantation

The concept of transplantation dates back to ancient times when physicians attempted to replace damaged or diseased organs with healthy ones. However, it was not until the 20th century that significant advancements were made in this field.

In 1954, Dr. Joseph Murray performed the first successful kidney transplant in the United States. Since then, numerous transplantations have been performed worldwide, including heart, liver, lung, and pancreas transplants.

Section 2: Techniques of Transplantation

There are two primary techniques used in transplantation: homograft and allograft. Homografts involve using tissue or organs from the same individual, while allografts involve using tissue or organs from a different individual.

Homografts are typically used in cases where the recipient's own tissue is damaged or diseased, such as in reconstructive surgery. Allografts are more commonly used in organ transplantation, where a donor's tissue or organ is transplanted into a recipient's body.

Section 3: Challenges of Transplantation

Despite advancements in transplantation, there are still several challenges that need to be addressed. These include:

1. Immune rejection: When a foreign organ or tissue is introduced into the body, the immune system may attack it as a threat. To prevent this, patients are often given immunosuppressant drugs to reduce the immune response.

2. Compatibility issues: There may be compatibility issues between the donor's tissue and the recipient's body. For example, if the blood types do not match, there may be complications during the transplantation process.

3. Infection risk: There is always a risk of infection when introducing foreign tissue into the body. Antibiotics and other medications are often used to reduce this risk.

Section 4: Self-Debate Discussion

Debate: Should animals be used for organ transplantation research?

Pro: Animals are often used in transplantation research because they provide valuable insights into the human body and can help improve transplantation techniques.

Con: Using animals for research can be cruel and unnecessary, as there are alternative methods available, such as using human cells in a lab setting.

Section 5: Glossary

- Homograft: Tissue or organs taken from the same individual
- Allograft: Tissue or organs taken from a different individual
- Immune rejection: When the immune system attacks a foreign organ or tissue
- Compatibility issues: Issues that may arise when the donor's tissue does not match the recipient's body
- Infection risk: The risk of infection when introducing foreign tissue into the body

Conclusion:

Transplantation is a complex medical procedure that requires careful consideration of various factors. By understanding the history, techniques, and challenges associated with transplantation, we can better appreciate the importance of this field and its potential to save lives. As new technologies and techniques continue to emerge, it is essential to critically evaluate their impact on the field of transplantation and ensure that they are used responsibly and ethically.

**Introduction**

Graphic art is a form of visual communication that uses images and words to convey ideas and messages. It can be used in various fields such as advertising, packaging, publishing, and web design. In this lesson, we will learn about the history of graphic art, its different types, and how it can be used to create effective visual communications.

**Section 1: History of Graphic Art**

Graphic art has a long history that dates back to ancient civilizations. The first known examples of graphic art were cave paintings created by early humans. Over time, graphic art evolved to include other forms of visual communication such as hieroglyphics, pictographs, and logograms. In the Middle Ages, graphic art was used to create illuminated manuscripts, which were handwritten books that included decorative illustrations. During the Renaissance, graphic art became more advanced with the use of perspective, shading, and other techniques. In the 19th century, graphic art was revolutionized by the invention of lithography, which allowed for mass production of images. Today, graphic art is used in various forms of media, including books, magazines, newspapers, and digital media.

**Section 2: Types of Graphic Art**

There are several types of graphic art, each with its own unique characteristics and purposes. Some of the most common types include:

1. Advertising - This type of graphic art is used to promote products or services. It often includes catchy slogans, colorful images, and bold fonts to grab the viewer's attention.

2. Packaging - Graphic art is used to create attractive packaging for products. This type of art must be visually appealing and convey information about the product.

3. Editorial - This type of graphic art is used in magazines, newspapers, and other publications to illustrate stories and convey information. Editorial art may include photographs, illustrations, and other visual elements.

4. Book design - Graphic art is used to create visually appealing covers and interiors for books. Book design must be consistent with the theme of the book and attract readers' attention.

**Section 3: Creating Effective Visual Communications**

To create effective visual communications, graphic artists must consider several factors. These include:

1. Target audience - The intended audience for the graphic art must be considered when creating the design. The style, tone, and message must appeal to the target audience.

2. Color - Color plays a significant role in graphic art. The choice of colors must be appropriate for the intended message and audience.

3. Typography - The selection of fonts and their arrangement is crucial in graphic art. Typography must be legible, consistent, and appropriate for the intended message.

4. Layout - The arrangement of elements on the page is essential in graphic art. Elements must be placed in a way that is visually pleasing and conveys the intended message.

**Conclusion**

Graphic art is a powerful tool for visual communication. By understanding its history, types, and best practices, graphic artists can create effective visual communications that convey messages and ideas to audiences. Whether you are creating advertisements, packaging, editorial art, or book designs, the principles of graphic art can help you create compelling visual communications that resonate with your audience.

The DA believes that the latest Eskom expose could be one of the reasons why its board has been reluctant to release the Dentons report.

The party was reacting to a Sunday Times article that alleges Eskom CEO Matshela Koko’s stepdaughter, Koketso Choma, 26, scored contracts worth R1 billion for her company from the parastatal.

DA MP Natasha Mazzone said the party would be writing to Public Protector Busisiwe Mkhwebane, requesting that she launch an investigation into Koko.

“Koko’s reported actions could show that he is compromised and unfit to be the head of Eskom,” Mazzone said.

“By claiming that he was not aware that his daughter was involved with Impulse International, Koko inadvertently admits that he failed in his role as the Chief Accounting officer to conduct due diligence on the company profile of a potential Eskom service provider.”

Impulse International, of which Choma was a director until recently, was awarded eight contracts by Eskom’s generation unit during Koko’s tenure as the unit’s group executive.

“This potentially means that Eskom violated State Procurement guidelines set out by Treasury to guide the acquisition of services by State Owned Enterprises under Koko’s stewardship.”

She said it was not acceptable that, while Eskom was struggling to raise capital for some of its power generation projects needed to grow the economy, its managers could be busy “siphoning cash to benefit family members”.

The long-awaited Dentons report on Eskom sheds light on shocking financial abuses.

News24 used a Promotion of Access to Information Act (PAIA) application to obtain a copy of the report, which was commissioned by the Eskom board in 2015.

Dentons, the law firm appointed to conduct an audit into “the status of the business and challenges experienced by Eskom,” identified serious cause for concern regarding the manner in which Eskom awarded contracts for the supply of diesel and coal, among other shortcomings.

According to the report, some of the contractors – who benefitted from the nearly R30 billion that Eskom spent on diesel for its open cycle gas turbines between 2013 and 2015 – were companies that had no footprint in the industry and that may have been set up by Eskom employees themselves, News24 reported.

Lesson: Introduction to Airstream Trailers

### Overview

In this lesson, we will learn about Airstream trailers, their history, and how they have evolved over time. We will also explore the role that Wally Byam and Neil Vanderbilt played in the creation of these iconic travel trailers.

### Section 1: History of Airstream Trailers

Airstream trailers were first introduced in 1929 by Wally Byam, a man who loved to travel and camp. He wanted to create a travel trailer that was lightweight, easy to tow, and comfortable to live in. The first Airstream trailers were made of aluminum, which made them lightweight and durable. They were also designed with a unique shape that allowed them to slide through the air like a stream of air.

In the early 1930s, Airstream trailers became popular among families who loved to camp. However, during World War II, production of Airstream trailers was halted due to the war effort. After the war, Airstream trailers were produced again, and they became even more popular.

In 1948, Wally Byam met Neil Vanderbilt, Jr., a writer and filmmaker. The two men decided to tour Europe together in an Airstream trailer. Vanderbilt documented their trip through his writing and filmmaking, which helped to spread the word about Airstream trailers.

### Section 2: The Commodore and Its Design

In 1952, Wally Byam and Neil Vanderbilt designed a new Airstream trailer called the Commodore. This trailer was state-of-the-art and featured many new innovations, such as a new aluminum skin that made the trailer lighter and stronger. The Commodore also had a new interior design that was more luxurious than previous Airstream models.

The Commodore was unveiled at the Chicago Auto Show in 1952. It was an instant hit and received a lot of attention from the media. The trailer was so popular that it sold for $10,000, which was a lot of money at the time.

### Section 3: The Impact of the Commodore

The success of the Commodore helped to solidify Airstream's reputation as a leader in the travel trailer industry. The trailer's unique design and innovative features set it apart from other travel trailers on the market.

The Commodore also helped to introduce Airstream trailers to a wider audience. Before the Commodore, Airstream trailers were primarily used by families for camping trips. However, the Commodore's luxurious design made it appealing to a wider range of people, including those who wanted a luxury RV for traveling.

### Glossary

- Airstream: A brand of travel trailers that are known for their aluminum construction and unique shape.
- Aluminum: A lightweight metal that is often used in the construction of Airstream trailers.
- RV: An acronym that stands for "recreational vehicle," which is a type of vehicle that can be used for both transportation and living quarters.
- Luxury: A term used to describe items or experiences that are considered to be of high quality and expensive.

### Conclusion

In conclusion, Airstream trailers have a rich history that dates back to the 1920s. The company has evolved over time, introducing new models and features that have helped to solidify its reputation as a leader in the travel trailer industry. The Commodore, in particular, was a groundbreaking model that helped to introduce Airstream trailers to a wider audience. By learning about the history of Airstream trailers and the impact of the Commodore, we can gain a deeper appreciation for the innovation and creativity that went into their design.

Michu: Not for sale at any price

The Gunners have so far been frustrated in their efforts to bring in Luis Suarez from Liverpool and are reportedly considering alternatives as Arsene Wenger looks to bolster his forward options.

Michu is thought to be one of those alternatives after the 27-year-old Spaniard enjoyed a stunning first season in English football with the Swans, scoring 22 goals after his £2.2million move from Rayo Vallecano.

Michu signed a four-year contract with the Swans in January, and Laudrup has previously stated he values the forward at least £30million.

And the Dane has told Arsenal there is no way Swansea will sell a key player when they would themselves be left with so little time to replace him.

"I think economically the club is very good," said Laudrup. "I know if they (Arsenal) came in with a very late bid, I know that the reaction from the board and chairman will be 'No', even if the money is ridiculous, as we will not have time enough to find a replacement who is near enough to the same standard.

"You can say we would get a lot of money but why be the richest club in the championship? What is that worth?

"I spoke to Michu last year and he extended his contract and asked me about mine and I said 'I am going to stay here', and he said, 'So am I'."

Laudrup has looked to ease the burden on Michu this season with the signing of Wilfried Bony for a club-record fee of £12million from Vitesse Arnhem.

Bony's arrival has allowed Michu to move back into his preferred attacking midfield role, and Laudrup expects him to weigh in with another healthy goalscoring tally this season.

He said: "Michu is an offensive midfielder who can play centre-forward but he will be a goalscorer wherever he plays.

"He is not only a goalscorer who is up there, waiting. When he plays in midfield he is working very hard and physically he has a presence and fills a lot of space as well.

"I see him more as an offensive midfielder. He can come in from that second line where he is so gifted.

"Of his 22 goals last season, I think 20 of his goals were first touch which shows how effective he is."

Vertical root fracture in endodontically versus nonendodontically treated teeth: a survey of 315 cases in Chinese patients.
The purpose of this study was to compare endodontically versus nonendodontically treated teeth with respect to clinical features, including patient age and gender and tooth types of vertical root fractures. A total of 315 consecutive cases of vertical root fracture occurring in 274 Chinese patients during a 1 3-year period were reviewed. Age and gender, as well as tooth type and root distribution of vertical root fractures, were presented and compared in endodontically versus nonendodontically treated teeth. Most patients (87%) had 1 fractured tooth; the others had 2 or 3 fractured teeth. Of all vertical root fractures, 40% occurred in nonendodontically treated teeth. In comparison with those in endodontically treated teeth, vertical root fractures in nonendodontically treated teeth tended to occur in patients with a higher mean age (55 years vs. 51 years) and were more frequent in male patients (78% vs. 58%). Vertical root fractures occurred in nonendodontically treated teeth more often in molars (84% vs. 53%), less often in premolars (16% vs. 33%), and seldom in anteriors (1 tooth vs. 27 teeth). Vertical root fractures in nonendodontically treated teeth are not uncommon and comprise a large proportion of such fractures in Chinese patients. Differences between endodontically and nonendodontically treated teeth in patient age and gender, as well as in tooth types of vertical root fractures, were demonstrated.

textbook:
Lesson: Understanding Vertical Root Fractures in Teeth

Introduction:
In dentistry, a vertical root fracture is a crack that extends from the root apex towards the crown of the tooth. This type of fracture is often caused by excessive force on the tooth, such as during a fall or sports injury. In this lesson, we will explore the differences between vertical root fractures in endodontically and non-endodontically treated teeth, and discuss the clinical features and treatment options for these conditions.

Section 1: Understanding Endodontic Treatment
Endodontic treatment, also known as root canal therapy, is a procedure used to save teeth that have been damaged by decay or injury. During this treatment, the pulp (the soft tissue inside the root canal) is removed, and the canal is cleaned and sealed to prevent further infection.

Questions:
- What is endodontic treatment?
- How does endodontic treatment prevent further damage to the tooth?

Answer:
Endodontic treatment is a procedure that involves removing the pulp and cleaning and sealing the root canal to prevent further infection. This treatment can save teeth that would otherwise need to be extracted.

Section 2: Comparing Vertical Root Fractures in Endodontically and Non-Endodontically Treated Teeth
A study conducted on 315 cases of vertical root fracture in Chinese patients found that 40% of these fractures occurred in non-endodontically treated teeth. The study also found that patients with non-endodontically treated teeth tended to be older than those with endodontically treated teeth.

Questions:
- What percentage of vertical root fractures occur in non-endodontically treated teeth?
- How does the age of the patient affect the likelihood of developing a vertical root fracture?

Answer:
According to the study mentioned above, 40% of vertical root fractures occurred in non-endodontically treated teeth. Additionally, patients with non-endodontically treated teeth tended to be older than those with endodontically treated teeth.

Section 3: Clinical Features and Treatment Options
The clinical features of vertical root fractures can vary depending on whether the tooth has undergone endodontic treatment or not. In general, however, the following features are common in both cases:

- Pain upon chewing or biting
- Sensitivity to temperature changes
- Discoloration of the tooth
- Swelling and inflammation around the tooth

Treatment options for vertical root fractures include:

1. Root canal therapy: If the tooth has not yet experienced trauma, root canal therapy may be performed to strengthen the tooth and prevent further damage.

2. Extraction: If the tooth is severely damaged or the patient is experiencing significant pain, extraction may be the best course of action.

3. Surgical intervention: In some cases, surgery may be necessary to repair the fracture and save the tooth.

Questions:
- What are the clinical features of vertical root fractures?
- What are the treatment options for vertical root fractures?

Answer:
The clinical features of vertical root fractures include pain upon chewing or biting, sensitivity to temperature changes, discoloration of the tooth, and swelling and inflammation around the tooth. Treatment options include root canal therapy, extraction, and surgical intervention.

Glossary:
- Endodontic treatment: A procedure that involves removing the pulp and cleaning and sealing the root canal to prevent further infection.
- Vertical root fracture: A crack that extends from the root apex towards the crown of the tooth.
- Root canal: The hollow space within the root of a tooth that contains the pulp.

Conclusion:
Understanding the differences between vertical root fractures in endodontically and non-endodontically treated teeth is essential for dentists to provide appropriate treatment options for their patients. By examining the clinical features and treatment options for these conditions, dentists can help prevent further damage to the tooth and improve the patient's quality of life.

Is that possible to block traffics based on Source and destination in Cisco IPS 4200 series sensor.. IPS is installed in promiscous mode.. regars. Rajesh. Does anyone have answer to my query. yes, you can "shun" to a cisco firewall (PIX or ASA) or a cisco router. In both cases the IDS sensor will populate an ACL to block your attacker. You need to have some signatures action set to "shun" and of course enter the router/firewall information (IP, username, password) into your sensor.. Could you explain me.. Here's a good configuration guide to shunning with a 4200 series IPS sensor and a router.. Here are some other useful IPS config guides:

## Lesson: Introduction to Cisco IPS 4200 Series Sensor
### Section 1: What is Cisco IPS 4200 Series Sensor?
Cisco IPS 4200 Series Sensor is an intrusion prevention system that helps protect networks from attacks by monitoring network traffic for malicious activity and blocking those attacks in real-time. It is designed to detect and prevent attacks such as viruses, worms, Trojans, and other malware that could harm your network or steal sensitive data.
### Section 2: How does Cisco IPS 4200 Series Sensor work?
The Cisco IPS 4200 Series Sensor works by analyzing network traffic using a set of rules or signatures that are designed to identify malicious activity. These rules are based on known attack patterns and are constantly updated to keep up with the latest threats. When the sensor detects a potential attack, it generates an alert and takes action to prevent the attack from succeeding. This action can include blocking the attacker's IP address, shutting down the affected device, or notifying security personnel.
### Section 3: How to configure Cisco IPS 4200 Series Sensor?
To configure the Cisco IPS 4200 Series Sensor, you will need to follow these steps:
1. Connect the sensor to your network and power it on.
2. Configure the sensor's management interface by entering the IP address, username, and password.
3. Configure the sensor's detection engine by selecting the appropriate rule sets and signatures.
4. Configure the sensor's action policies to determine how the sensor will respond to detected attacks.
5. Test the sensor to ensure that it is properly detecting and blocking attacks.
### Section 4: Practical Examples
Let's consider a few practical examples to understand how Cisco IPS 4200 Series Sensor works in real-world scenarios.
Example 1: A user tries to access a website that contains malware. The Cisco IPS 4200 Series Sensor detects the malware and blocks the user's access to the website, preventing the malware from infecting the user's computer.
Example 2: An attacker attempts to exploit a vulnerability in a web application by sending a malicious HTTP request. The Cisco IPS 4200 Series Sensor detects the vulnerability and blocks the attacker's IP address, preventing them from launching further attacks.
Example 3: A user downloads a file from a website that contains a virus. The Cisco IPS 4200 Series Sensor detects the virus and quarantines the file, preventing it from spreading to other computers on the network.
### Section 5: Glossary
- Rule Set: A collection of rules or signatures that are used to detect attacks.
- Signature: A unique pattern or fingerprint that is associated with a particular attack or malware.
- Action Policy: A set of rules that determines how the Cisco IPS 4200 Series Sensor will respond to detected attacks.
- Quarantine: The process of isolating a infected or suspicious file to prevent it from causing further damage.
### Conclusion
In this lesson, we have learned about the Cisco IPS 4200 Series Sensor, how it works, and how to configure it. We have also considered practical examples to demonstrate how the sensor can be used to protect against attacks. By understanding the principles behind intrusion prevention systems, we can better protect our networks and data from malicious activity.

**Title: Introduction to OpenStreetMap**

**Section 1: What is OpenStreetMap?**
OpenStreetMap (OSM) is a collaborative project to create a free editable map of the world. It is built by people like you who contribute their time and effort to create and maintain the map. OSM is available under an open license, which means that anyone can use, share, or modify the map for any purpose.

**Section 2: How does OpenStreetMap work?**
OSM works by allowing users to add and edit map data. This data includes everything from roads and buildings to parks and natural features. Users can add this data by walking around with a GPS device or by using aerial imagery. Once the data is collected, it is uploaded to the OSM server, where other users can review and edit it. This process is called "tagging" and involves assigning attributes to different features on the map.

**Section 3: Why use OpenStreetMap?**
There are many reasons why someone might want to use OSM. For example, if you are planning a trip, OSM can help you find your way around an unfamiliar city. If you are a developer, you can use OSM data to create maps or other applications. And if you are a researcher, you can use OSM data to study how urban areas are changing over time.

**Section 4: Practical Examples**
Let's say you want to add a new road to OSM. You would use a GPS device to collect the data and then upload it to the OSM server. Once the data is there, other users can review it and make suggestions for improvements. If you accept their suggestions, the road will be added to the map.

**Section 5: Conclusion**
In conclusion, OpenStreetMap is a powerful tool for creating and sharing map data. By contributing your time and effort, you can help improve the map and make it more useful for everyone. Whether you are a tourist, a developer, or a researcher, OSM has something to offer. So get out there and start mapping!

**Glossary**
- GPS: Global Positioning System
- Tagging: Assigning attributes to features on the map
- Aerial imagery: High-altitude photographs of the Earth's surface
- Attributes: Characteristics of a feature on the map

**Conclusion**
In this lesson, we learned about OpenStreetMap, how it works, and why it is useful. We also looked at some practical examples of how to contribute data to the map. By understanding the basics of OSM, you can become a valuable contributor to this global project.

Looking back on St. Paul's Ford plant

The St. Paul Ford plant has a long and rich history. Recent attempts to keep the sprawling plant from closing next year have failed.

State and city officials asked Ford to reconsider the decision to close down the plant for good, offering various incentives to keep the facility and its jobs in St. Paul. Ford declined the offers.

Morning Edition's Cathy Wurzer talked with history professor Annette Atkins about the plant and its place in St. Paul history. Atkins teaches history at St. John's University and the College of St. Benedict in central Minnesota.

Stability of transgenes in long-term micropropagation of plants of transgenic birch (Betula platyphylla).
The stability of integration and expression level of transgenes in long-term micropropagation clones of transgenic birch (Betula platyphylla Suk.) was examined. Multiplexed PCR and reverse primer PCR demonstrated stable integration of transgenes into regenerated plants. Expression levels of the bgt and gus genes among shoot plantlets, subcultured 4, 7, 9 and 15 times, were significantly different. The transcriptional expression level of extraneous genes in regenerated plants decreased with increasing subculture number. Transcriptional gene silencing (TGS) occured in regenerated transgenic lines. The silencing rate of GUS in the 5th subculture plants was 22-65%. TGS in regenerated plants could be reactivated with 5-azacytidine (Azac) at 50-200 microM. GUS and BGT protein expression was reactivated in the micropropagated transgenic birch plants when treated with Azac. A decrease in expression level with increasing number of subcultures is thus associated with DNA methylation.

Lesson: Stability of Transgenes in Long-Term Micropropagation of Plants
Introduction:
Transgenic plants are those that have been genetically modified to contain genes from other organisms. These genes can be used to improve crop yield, resistance to pests, and other traits. However, the stability of these transgenes in long-term micropropagation is an important concern.
Core Value:
The stability of integration and expression level of transgenes in long-term micropropagation clones of transgenic birch (Betula platyphylla Suk.) was examined.
Lesson Plan:
I. What is micropropagation?
- Micropropagation is a process of growing plant cells, tissues, or organs under sterile conditions in a nutrient medium.
- It is used to produce large numbers of genetically identical plants quickly and efficiently.
- Micropropagation is used in agriculture, horticulture, and forestry to produce disease-free, high-quality plants.
II. What are transgenes?
- Transgenes are genes that have been transferred from one organism to another.
- They can be used to improve crop yield, resistance to pests, and other traits.
- Transgenes can be inserted into plants using various techniques, such as Agrobacterium-mediated transformation or biolistic methods.
III. How are transgenes stabilized in long-term micropropagation?
- Multiplexed PCR and reverse primer PCR demonstrate stable integration of transgenes into regenerated plants.
- Expression levels of the bgt and gus genes among shoot plantlets, subcultured 4, 7, 9 and 15 times, were significantly different.
- Transcriptional gene silencing (TGS) occurred in regenerated transgenic lines.
- The silencing rate of GUS in the 5th subculture plants was 22-65%.
- TGS in regenerated plants could be reactivated with 5-azacytidine (Azac) at 50-200 microM.
- GUS and BGT protein expression was reactivated in the micropropagated transgenic birch plants when treated with Azac.
IV. Why is stability of transgenes important?
- Stability of transgenes is important because it ensures that the desired traits will be passed on to future generations of plants.
- If transgenes are not stable, then the benefits of genetic modification may not be realized.
V. Conclusion:
- In conclusion, the stability of integration and expression level of transgenes in long-term micropropagation clones of transgenic birch (Betula platyphylla Suk.) was examined.
- Multiplexed PCR and reverse primer PCR demonstrated stable integration of transgenes into regenerated plants.
- Expression levels of the bgt and gus genes among shoot plantlets, subcultured 4, 7, 9 and 15 times, were significantly different.
- Transcriptional gene silencing (TGS) occurred in regenerated transgenic lines.
- The silencing rate of GUS in the 5th subculture plants was 22-65%.
- TGS in regenerated plants could be reactivated with 5-azacytidine (Azac) at 50-200 microM.
- GUS and BGT protein expression was reactivated in the micropropagated transgenic birch plants when treated with Azac.
VI. Glossary:
- Micropropagation: the process of growing plant cells, tissues, or organs under sterile conditions in a nutrient medium to produce large numbers of genetically identical plants quickly and efficiently.
- Transgenes: genes that have been transferred from one organism to another.
- Agrobacterium-mediated transformation: a technique used to insert transgenes into plants using Agrobacterium tumefaciens, which transfers the desired gene to the plant's genome.
- Biolistic methods: a technique used to insert transgenes into plants by using a gene gun or a helium-based system to shoot DNA particles into plant cells.
- Transcriptional gene silencing (TGS): a process where the expression of extraneous genes in regenerated plants decreases with increasing subculture number.
- 5-azacytidine (Azac): a drug that can reactivate TGS in regenerated transgenic lines.
VII. Self-Debate:
- Is it safe to consume genetically modified foods?
- Some people argue that genetically modified foods are safe, while others argue that they may cause health problems.
- Do the potential benefits of genetically modified foods outweigh the risks?
VIII. Practical Examples:
- A farmer wants to grow a crop that is resistant to a specific pest. They decide to use a transgene that produces a protein toxic to the pest but harmless to humans and other animals.
- The farmer uses micropropagation to produce large numbers of genetically identical plants containing the transgene.
- Over time, the expression of the transgene decreases, and the pest becomes resistant to the toxic protein.
- The farmer must use additional methods, such as insecticides, to control the pest population.
IX. Real-World Scenarios:
- A company wants to produce a genetically modified plant that produces a specific protein used in medicine.
- They use micropropagation to produce large numbers of genetically identical plants containing the desired transgene.
- The company must ensure that the transgene is stable over time to ensure the desired protein is produced consistently.
X. Conclusion:
- In conclusion, the stability of transgenes in long-term micropropagation of plants is an important concern.
- The core value of this study is the stability of integration and expression level of transgenes in long-term micropropagation clones of transgenic birch (Betula platyphylla Suk.).
- Multiplexed PCR and reverse primer PCR demonstrated stable integration of transgenes into regenerated plants.
