text: T-Mobile has been relegated to being America’s #4 U.S. carrier, thanks to it’s failed acquisition deal with AT&T. Apparently, the company has some big plans to put it back in the spotlight though.. T-Mobile just sent out invites to an exclusive event on March 26th in New York, where it is expected to detail plans to change its wireless business.. T-Mobile has been working to launch its own LTE network this year and already has a few cities that are ready for customers. Along with the new network, T-Mobile announced late last year that they’ve secured a deal with Apple to sell the iPhone in 2013.. It’s unlikely that the T-Mobile event will include the revealing of when the carrier will start to sell the iPhone, but maybe it will announce unlimited data plans and price points that will make it more competitive with AT&T and Verizon.

East Leeds Family Learning Centre

East Leeds Family Learning Centre was a large Adult Education Centre in Seacroft, Leeds, England.   The buildings were originally used as a secondary school, Foxwood School.  The school is notable for its use for filming The Beiderbecke Trilogy between 1984 and 1988.  Demolition of the buildings began in December 2009 and was completed early in 2010.

History

The centre was in the buildings of the former Foxwood School, later East Leeds High School.  The school originally opened as an all-boys school, but changed in September 1971 to a mixed gender school.  The David Young Academy is now the largest school in Seacroft and effectively replaced East Leeds High School.

Pupils from the Seacroft area often attend John Smeaton Academy, Wetherby High School, Boston Spa School and Garforth Community College the latter three which are served by school bus routes operated by the West Yorkshire Passenger Transport Executive.

Use in Television
The buildings were most notable for their use as 'San Quentin High', in the Yorkshire Television programmes The Beiderbecke Affair, The Beiderbecke Tapes and The Beiderbecke Connection.  The shots used of the staff room and hall in the Beiderbecke Tapes were in fact that of Moor Grange County Secondary School in Ireland Wood.  In the series, references were made to the fictional inner-city school being run-down in the later decades of its use. The internal buildings and school grounds were used for filming in the CITV series "Adam's Family Tree"  which aired between 1997 and 1999.

Demolition

The buildings were in a somewhat derelict state, built six storeys high at their tallest and set around a central courtyard.  Much of the building surfaces were glazed, providing natural light throughout the corridors, which largely ran along the edge of buildings, a feature Yorkshire Television exploited for filming.
Demolition began on the northern sections of the building in December 2009, following a decision by Leeds City Council that the building was unfit for purpose and uneconomic to repair.

No plans have as yet being put forward for the redevelopment of the site.  Many prefabricated 'Cedarwood' houses in the area are abandoned and likely to be demolished in the near future raising the possibility that the site may be redeveloped as part of a wider scheme.

Former Staff
Former Labour MP Colin Burgon (for neighbouring Elmet Constituency between 1997 and 2010) was a history teacher at the school and grew up in neighbouring Gipton.

Title: Introduction to Algebra

## Chapter 1: What is Algebra?

### Section 1: What is Algebra?

Algebra is a branch of mathematics that uses letters and symbols to represent numbers and values. It is used to solve equations, which are statements that two expressions are equal. Algebra is divided into several areas, including linear algebra, abstract algebra, and algebraic geometry.

### Section 2: Why is Algebra Important?

Algebra is important because it is used in many fields, including science, engineering, and finance. It is also used in everyday life, such as when calculating tips at a restaurant or figuring out how much change you will receive. Algebra helps us understand patterns and relationships, which can be useful in many situations.

### Section 3: How does Algebra work?

Algebra uses variables, which are letters or symbols that represent unknown values. For example, x might represent the value of a variable in an equation. Algebra also uses operations, such as addition, subtraction, multiplication, and division, to manipulate these variables. By using algebraic equations, we can solve for the value of the variable.

### Section 4: Example of an Algebra Problem

Solve for x: 2x + 5 = 15

To solve this problem, we need to isolate the variable x on one side of the equation. First, we'll subtract 5 from both sides:

2x + 5 - 5 = 15 - 5
2x = 10

Next, we'll divide both sides by 2 to solve for x:

2x / 2 = 10 / 2
x = 5

So, the solution to the equation 2x + 5 = 15 is x = 5.

### Conclusion

In this lesson, we learned what algebra is and why it is important. We also learned how algebra works by using variables and operations to solve for unknown values. Finally, we solved an example algebra problem to demonstrate how to use algebra to solve equations. By understanding the basics of algebra, we can use this powerful tool to solve many types of problems in our daily lives.

Title: Garden Weeding Tools: Choosing the Right Ones for Your Garden

Introduction:
Garden weeding tools are essential for maintaining a healthy and beautiful garden. They help to remove unwanted plants, such as weeds, that compete with your desired plants for nutrients and space. In this lesson, we will learn about the different types of garden weeding tools, their uses, and how to choose the right ones for your garden.

Section 1: Types of Garden Weeding Tools
There are several types of garden weeding tools available, each with its unique features and purposes. Some of the most common types include:

1. Hand Trowel: A hand trowel is a small, lightweight tool that is used for digging small holes, transplanting seedlings, and weeding around plants. It has a flat, thin blade that is ideal for breaking up soil without damaging delicate roots.

2. Weeding Fork: A weeding fork is a long-handled tool that has a series of thin, sharp tines. It is used for lifting and removing weeds, especially those with deep roots. The fork allows you to get under the plant and gently lift it out without damaging the surrounding plants.

3. Weeder Hoe: A weeder hoe is a tool that has a thin, flat blade set at an angle. It is used for slicing through weeds and grass at the surface of the soil. The hoe can be used to create a clean edge around walkways or garden beds, and it is also useful for removing small weeds before they have a chance to grow.

4. Ground Cover Fabric: Ground cover fabric is a material that is placed over the soil to prevent weeds from growing. It is particularly useful in areas where weeds are difficult to control, such as rock gardens or steep slopes.

5. Mulch: Mulch is a layer of material that is spread over the soil to suppress weed growth. It can be made from organic materials like wood chips, straw, or leaves, or from inorganic materials like stone or gravel.

Section 2: How to Choose the Right Garden Weeding Tool
Choosing the right garden weeding tool depends on several factors, including the type of plants you have in your garden, the size of your garden, and your personal preferences. Here are some tips to help you choose the right tool for your needs:

1. Consider the size of your garden: If you have a large garden, you may want to invest in a power weeder or a cultivator to make the task of weeding easier and faster. If you have a small garden, a hand trowel or weeder hoe may be all you need.

2. Think about the types of weeds you have: Some weeding tools are better suited for certain types of weeds. For example, if you have deep-rooted weeds, a weeding fork may be more effective than a weeder hoe. If you have shallow-rooted weeds, a weeder hoe may be a better choice.

3. Consider your personal preferences: Some people prefer manual tools that require physical effort, while others prefer tools that require less effort, such as a power weeder. Choose a tool that you feel comfortable using and that fits your personal preferences.

Section 3: Practical Examples and Real-World Scenarios
Let's look at some practical examples of how to use garden weeding tools in real-world scenarios:

1. Hand Trowel: To use a hand trowel for weeding, hold the handle with one hand and the blade with the other. Place the blade against the soil and push down to dig up the weed. Be careful not to damage nearby plants.

2. Weeding Fork: To use a weeding fork, hold the handle with one hand and the tines with the other. Insert the tines into the soil near the base of the weed and gently lift up and out. Be careful not to damage nearby plants.

3. Weeder Hoe: To use a weeder hoe, hold the handle with one hand and the blade with the other. Swipe the blade back and forth across the soil surface to slice through the weeds. Be careful not to hit nearby plants.

Conclusion:
In conclusion, garden weeding tools are essential for maintaining a healthy and beautiful garden. By choosing the right tool for your needs and using it correctly, you can effectively remove unwanted plants and keep your garden looking its best. Remember to use these tools safely and to always be mindful of the plants around you.

## Section 1: Theoretical Concepts
In this lesson, we will learn about the music industry and its various components. We will also explore the roles and responsibilities of different professionals involved in the industry.
### Topic 1: The Music Industry
The music industry is a broad term that refers to the business side of music. It includes various components such as recording, publishing, promoting, and selling music. The industry is divided into two main categories: the recording industry and the performance industry.
### Topic 2: Roles and Responsibilities
There are several roles and responsibilities within the music industry. Some of the most common ones include:
- Record companies: These are responsible for producing, marketing, and distributing music recordings.
- Artists: These are the people who create and perform music. They may be singers, musicians, songwriters, or producers.
- Managers: These professionals manage the careers of artists and help them achieve their goals.
- Agents: These individuals represent artists and negotiate contracts on their behalf.
- Promoters: These professionals organize concerts and events to promote the music of artists.
## Section 2: Practical Examples
Let's take a look at some practical examples of how the music industry works.
### Example 1: Recording Contracts
When an artist signs a recording contract, they agree to produce a certain number of albums for the record company. In return, the company agrees to promote and distribute the music. The contract usually includes details such as royalties, advances, and ownership of the master recordings.
### Example 2: Touring
Touring is an important part of an artist's career. It allows them to perform live and connect with their fans. However, it can also be expensive. Artists must pay for transportation, accommodations, and other expenses. Promoters also have to invest money in advertising and other costs to ensure that the concert is successful.
## Section 3: Real-World Scenarios
Now let's take a look at some real-world scenarios that demonstrate the importance of the music industry.
### Example 1: Streaming Services
Streaming services such as Spotify and Apple Music have changed the way that people listen to music. They allow users to access millions of songs on demand, making it easier than ever to discover new music. However, they also pose a challenge to the traditional music industry. Many artists feel that they are not receiving enough compensation for their work.
### Example 2: Piracy
Piracy is the unauthorized copying and distribution of copyrighted material. In the music industry, piracy has had a significant impact on sales. Many people download music illegally rather than buying it. This has led to a decline in revenue for record companies and artists.
## Glossary
- Record company: A company that produces, markets, and distributes music recordings.
- Artist: A person who creates and performs music.
- Manager: A professional who manages an artist's career and helps them achieve their goals.
- Agent: A person who represents artists and negotiates contracts on their behalf.
- Promoter: A professional who organizes concerts and events to promote the music of artists.
## Conclusion
In this lesson, we learned about the music industry and its various components. We also explored the roles and responsibilities of different professionals involved in the industry. By understanding these concepts, we can better appreciate the hard work and dedication that goes into creating and promoting music.

Lesson: How to Create a Professional Bio

Introduction:
A professional bio is a short summary of your skills, experiences, and achievements. It is often used on websites, social media profiles, or resumes to introduce yourself to potential employers, clients, or colleagues. In this lesson, we will learn how to create an effective professional bio that showcases your strengths and sets you apart from others.

Section 1: Understanding Your Audience

Before creating your bio, you need to understand who your audience is. Are you creating a bio for a job application, a personal website, or a social media profile? Knowing your audience will help you tailor your bio to their interests and expectations.

Questions:
- Who is your target audience?

Q:

Redirect URI into subpage.php and read is as parameter by .htaccess

I would like to redirect URI into subpage.php and read is as parameter (by $_GET method).
Example 1:
http://homepage.com/wap/show_counties.php?id_county=51&char_county=&lang=en
into
http://homepage.com/controller.php?url=wap/show_counties.php?id_county=51&char_county=&lang=en (??? - can I pass url parameter like this?)
Example 2:
http://homepage.com/accommodation/hostel-star-bratislava
into
http://homepage.com/controller.php?url=accommodation/hostel-star-bratislava
Example 3:
http://homepage.com/en/search-in-page-12.html?ordering=newest&searchphrase=any&searchword=do%25252525252525252525252B700%252525252525
into
http://homepage.com/controller.php?url=en/search-in-page-12.html?ordering=newest&searchphrase=any&searchword=do%25252525252525252525252B700%252525252525 (??? - can I pass url parameter like this?)
EDIT: I would like to make url redirection by .htaccess
Could you help me please?
Regards
Jan Zitniak

A:

You can do this with mod_rewrite. What you want to do can be described like so:

The request uri should be passed to a specific file in a get variable
If there is an original query string, it should be retained

You can do this with the QSA (query string append) flag in mod_rewrite. In addition to that, in the example below I add a condition that checks if the file that is requested does not exist. This prevents the rule from matching itself (controller.php exists) and prevents the rule from working on files that are typically not handled by a controller (js/css/images). Add the following to the beginning of the .htaccess in your www-root:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ /controller.php?url=$1 [QSA,L]

See the documentation for mod_rewrite in general and the document about flags specific for more information.

textbook:
To redirect a URL using .htaccess, you can use the RewriteEngine directive to specify the rules for redirecting the URL. Here's an example rule that will redirect any request to show_counties.php to controller.php with the original URL as a parameter:

RewriteCond %{THE_REQUEST} ^[A-Z]+\ show_counties\.php\?id_county=51&char_county=&lang=en [NC]
RewriteRule ^ show_counties\.php$ [L,R=301,NE]

This rule checks if the request is for show_counties.php with the specified parameters, and if so, redirects it to controller.php with the original URL as a parameter.

To redirect other examples, you can modify the rule accordingly. For example, to redirect accommodation/hostel-star-bratislava to controller.php, you can use this rule:

RewriteCond %{THE_REQUEST} ^[A-Z]+\ accommodation\/hostel-star-bratislava [NC]
RewriteRule ^ accommodation\.php$ [L,R=301,NE]

And for search-in-page-12.html, you can use this rule:

RewriteCond %{THE_REQUEST} ^[A-Z]+\ search-in-page-12\.html\?ordering=newest&searchphrase=any&searchword=do%252525252525252525252B700%252525252525 [NC]
RewriteRule ^ search-in-page\.php$ [L,R=301,NE]

These rules assume that your original URLs are structured like this:

- show_counties.php: /wap/show_counties.php?id_county=51&char_county=&lang=en
- accommodation/hostel-star-bratislava: /accommodation/hostel-star-bratislava
- search-in-page-12.html: /en/search-in-page-12.html?ordering=newest&searchphrase=any&searchword=do%252525252525252525252B700%252525252525

Note that the rules assume that the requested URL is case-insensitive. If that's not the case, you may need to add the [NC] flag to make the rule case-insensitive.

Once you have defined the rules, you can access the original URL as a parameter in PHP using the $_GET superglobal array. For example, if you want to get the value of the id_county parameter from the original URL, you can do this:

$original_url = $_GET['id_county'];

This will give you the value of the id_county parameter from the original URL, if it exists. You can then use this value to do whatever you need to do with it in your application.

Lesson: Exploring Distortion in Art

## Introduction
In this lesson, we will explore the concept of distortion in art. We will learn about the different techniques used by artists to create distorted images and how they use them to convey their message. We will also analyze some examples of distorted art and discuss their impact on the viewer.

## Section 1: Understanding Distortion in Art

Distortion in art refers to the deliberate manipulation of visual elements to create an image that deviates from the natural appearance of things. This can be achieved through various techniques such as exaggeration, stretching, warping, or skewing. Distortion is often used to convey a sense of unease, disorientation, or to draw attention to specific details in the artwork.

## Section 2: Techniques of Distortion in Art

There are several techniques that artists use to create distorted images. Some of these techniques include:

1. Exaggeration: This involves magnifying certain elements of the artwork to make them more prominent than others. For example, an artist might exaggerate the size of a person's nose or the color of their hair to draw attention to those features.

2. Stretching: This technique involves stretching or elongating certain parts of the image to create a sense of movement or tension. For example, an artist might stretch the edges of a building to make it appear as though it is leaning or twisting.

3. Warping: This involves distorting the shape or form of an object in the artwork. For example, an artist might warp a person's face to create a grotesque or unsettling effect.

4. Skewing: This technique involves distorting the perspective of an image to create a sense of disorientation. For example, an artist might skew the lines of a road or a building to make it appear as though it is tilting or twisting.

## Section 3: Analyzing Examples of Distorted Art

Let's take a closer look at some examples of distorted art to see how artists use these techniques to convey their message.

1. Salvador Dali's "The Persistence of Memory": In this famous surrealist painting, Dali uses distorted time and space to create a dreamlike, disorienting effect. The melting clocks and distorted landscape evoke a sense of unease and disorientation in the viewer.

2. Pablo Picasso's "Les Demoiselles d'Avignon": In this cubist painting, Picasso uses exaggerated perspectives and distorted figures to create a sense of tension and unease. The distorted forms and exaggerated lines convey a sense of fragmentation and disconnection.

3. Edvard Munch's "The Scream": In this iconic expressionist painting, Munch uses distorted colors and exaggerated lines to convey a sense of fear and anxiety. The distorted figure and vibrant colors create a sense of unease and disorientation in the viewer.

## Conclusion

In conclusion, distortion in art is a powerful tool that artists use to convey their message and evoke emotions in the viewer. By manipulating visual elements, artists can create images that challenge our perceptions of reality and provoke thought and discussion. Through this lesson, we have explored the techniques of distortion in art and analyzed some examples of distorted art to understand how these techniques are used to convey meaning.

Lesson: Understanding Conveyor Belts

Introduction:
A conveyor belt is a long, continuous piece of material that moves or "conveys" items from one place to another. They are commonly used in manufacturing, mining, and agriculture industries to transport goods and materials efficiently and safely. In this lesson, we will explore the different types of conveyor belts, their uses, and how they work.

Types of Conveyor Belts:
There are several types of conveyor belts available, each designed for specific tasks. The most common types include:

1. Flat Belt Conveyors: These are the most basic type of conveyor belt, consisting of a flat surface with a rubber or plastic coating. They are typically used for light-duty applications such as moving boxes or small parts.

2. Roller Conveyors: These conveyor belts consist of a series of rollers arranged in a row. They are often used to move heavy loads or to create inclines or declines.

3. Overhead Conveyors: As the name suggests, these conveyor belts are suspended from the ceiling. They are ideal for applications where floor space is limited or where materials need to be moved between different levels.

4. Belt Conveyors: These conveyor belts are similar to flat belt conveyors but have a more complex design. They can be customized to meet specific needs and are commonly used in industrial settings.

How Conveyor Belts Work:
Conveyor belts work by using a combination of friction and movement to transport objects. Here's a step-by-step breakdown of how they function:

1. The conveyor belt is powered by an electric motor, which turns the rollers or pulleys beneath the belt.

2. As the belt moves, objects placed on it will also move along the conveyor's path.

3. Friction between the belt and the surface it rests on keeps the objects in place as they travel along the conveyor.

4. At the end of the conveyor, the objects are discharged off the belt and onto a receiving area or conveyor.

Uses of Conveyor Belts:
Conveyor belts are used in a wide range of industries for various purposes, including:

1. Manufacturing: Conveyor belts are commonly used in assembly lines to move products from one stage to another.

2. Mining: Conveyor belts are used to transport raw materials such as coal, ore, and rock from the mine face to the processing plant.

3. Agriculture: Conveyor belts are used to move grain, hay, and other crops from the field to storage or processing facilities.

4. Logistics: Conveyor belts are used in warehouses and distribution centers to transport packages and boxes.

Conclusion:
In summary, conveyor belts are essential tools in many industries, enabling efficient and safe transportation of goods and materials. By understanding the different types of conveyor belts and how they work, we can apply this knowledge to solve problems and create innovative solutions.

Fasciola antigens as vaccines against fascioliasis and schistosomiasis.
Fascioliasis is an important trematode infection of herbivores worldwide with increasing evidence of prevalence as a disease of humans. Vaccination studies with purified native and recombinant Fasciola antigens suggest that this approach to diminished morbidity and mortality and reduced transmission is a realistic goal. Among the major potential vaccine candidates are fatty acid binding protein (FABP), cysteine (cathepsin) proteases, haemoglobulin, leucine aminopeptidase, and a saposin-like protein. In the case of Fasciola hepatica FABP, cross-reaction and cross-protection against Schistosoma mansoni is an important feature. In addition to protective effects with significant worm burden reductions, some vaccine candidates also have anti-fecundity (smaller flukes), anti-pathology (less liver lesions), and anti-embryonation effects. Optimism is tempered by the fact that fascioliasis in humans is an orphan disease and in need of governmental and foundation support.

Lesson: Vaccine Development Against Parasitic Infections

Introduction:
Parasitic infections are a major public health concern worldwide, affecting millions of people. Fascioliasis and schistosomiasis are two such infections caused by parasitic worms. In this lesson, we will learn about the development of vaccines against these infections using Fasciola antigens as a model.

Section 1: Understanding Parasitic Infections

1.1 What are parasitic infections?
Parasitic infections are diseases caused by parasites, which are organisms that live on or inside a host organism and benefit at the host's expense.

1.2 What are the common types of parasitic infections?
Some common types of parasitic infections include malaria, schistosomiasis, and fascioliasis.

Section 2: Fascioliasis and Schistosomiasis

2.1 What are Fasciola and Schistosoma?
Fasciola and Schistosoma are parasitic worms that cause fascioliasis and schistosomiasis, respectively.

2.2 How do these parasites infect humans?
Fasciola and Schistosoma enter human bodies through contaminated food or water. Once inside the body, they travel to the liver or blood vessels, where they reproduce and cause damage.

Section 3: Developing Vaccines Against Parasitic Infections

3.1 Why develop vaccines against parasitic infections?
Vaccines can help prevent infections and reduce the spread of diseases, saving lives and reducing healthcare costs.

3.2 What are the challenges in developing vaccines against parasitic infections?
Parasites are complex organisms with multiple life stages and host interactions, making it difficult to target all stages of their life cycle with a single vaccine.

3.3 What are the potential vaccine candidates for fascioliasis and schistosomiasis?
Potential vaccine candidates for fascioliasis and schistosomiasis include fatty acid binding protein (FABP), cysteine (cathepsin) proteases, haemoglobulin, leucine aminopeptidase, and a saposin-like protein.

Section 4: The Importance of Cross-Reactivity and Cross-Protection

4.1 What is cross-reactivity and cross-protection?
Cross-reactivity refers to the ability of an immune response to a vaccine to protect against other related pathogens. Cross-protection refers to the ability of a vaccine to protect against different strains of a pathogen.

4.2 Why is cross-reactivity and cross-protection important in vaccine development?
Cross-reactivity and cross-protection are important because they can lead to broader protection against related pathogens, reducing the need for multiple vaccines.

Section 5: Conclusion

5.1 How can we apply what we learned about vaccine development against parasitic infections?
By understanding the challenges and potential vaccine candidates for fascioliasis and schistosomiasis, we can work towards developing effective vaccines that can help reduce the burden of these diseases.

Lesson: Introduction to Chess

### Section 1: Theoretical Concepts

Chess is a two-player game played on a square board divided into 64 squares of alternating colors. Each player starts with 16 pieces: one king, one queen, two rooks, two knights, two bishops, and eight pawns. The objective of the game is to checkmate the opponent's king, where the king is under attack and cannot move to a safe square without remaining under attack.

### Section 2: Practical Examples

Let's consider a basic example of chess strategy. White opens with e4 to e5, which is called the King's Gambit. Black responds with e7 to e5, and white replies with nf3 to b5. Now, black has several options: they can play 5...a6 (the Sicilian Defense), 5...b6 (the French Defense), or 5...Nc6 (the Caro-Kann Defense). Each of these openings has its own set of strategies and tactics, but they all aim to control the center of the board and develop the pieces.

### Section 3: Self-Debating Discussions

1. What are some advantages of controlling the center of the board in chess?
2. How does the King's Gambit differ from other openings?
3. Can you explain the difference between strategies and tactics in chess?

### Glossary

- Center: The four squares e4, d4, e5, and d5, which are the central squares of the board.
- Development: The process of moving pieces to active positions on the board.
- Opening: The first few moves of a chess game, usually designed to gain an advantageous position.
- Strategy: A long-term plan to achieve a goal, while tactics refer to short-term moves to achieve a specific aim.

### Conclusion

Chess is a complex and strategic game that requires careful planning and execution. By understanding the basic rules and concepts, players can develop their skills and apply them to various scenarios. Whether playing for fun or competition, the lessons learned in chess can be applied to many aspects of life, such as problem-solving, decision-making, and critical thinking.

Lesson: How to Write a Good Cover Song

Introduction:
In this lesson, we will learn about the key elements of writing a good cover song. A cover song is a new performance or recording of a song that was originally written and performed by someone else. Cover songs have been a part of popular music for decades, and many famous artists have made their mark by reinterpreting classic songs. However, writing a good cover song requires skill, creativity, and knowledge of music theory.

Section 1: Understanding the Original Song
The first step in writing a good cover song is to understand the original song. This means listening to the song multiple times and analyzing its structure, melody, and lyrics. You should identify the song's tempo, key, and time signature, as well as any unique musical features such as instrumental solos or unusual chord progressions. Additionally, you should consider the emotional impact of the original song and how your cover might differ.

Section 2: Choosing the Right Song to Cover
Once you have a good understanding of the original song, you should choose a song that you think would benefit from a fresh interpretation. Consider the song's cultural significance, its place in music history, and whether it speaks to your audience. You should also choose a song that suits your voice and musical style.

Section 3: Adding Your Own Twist
The third step in writing a good cover song is to add your own twist to the song. This could involve changing the arrangement, adding new instruments, or altering the melody. You should avoid making drastic changes that would fundamentally change the meaning of the song, but you should feel free to experiment with different sounds and styles.

Section 4: Recording and Performing the Song
Once you have written your cover song, you should record and perform it for an audience. This will allow you to test your interpretation of the song and receive feedback from listeners. You should also be prepared to explain your creative choices and defend your interpretation of the song.

Conclusion:
Writing a good cover song requires skill, creativity, and knowledge of music theory. By understanding the original song, choosing the right song to cover, adding your own twist, and recording and performing the song, you can create a unique interpretation that will captivate audiences and stand the test of time.

Glossary:
- Cover song: A new performance or recording of a song that was originally written and performed by someone else.
- Arrangement: The way in which a song is composed and performed.
- Interpretation: An artist's rendition of a song, which may differ from the original version.
- Tempo: The speed or pace of a piece of music.
- Key: The set of notes and chords that a song is written in.
- Time signature: The number of beats per measure in a piece of music.

**The Environmental Impact of Improper Disposal of Refrigerators**

Refrigerators contain refrigerants, which are chemicals that help keep food cold. When refrigerators are improperly disposed of, these refrigerants are released into the atmosphere, causing damage to the ozone layer and contributing to climate change.

**The Legal Implications of Improper Disposal of Refrigerators**

Improper disposal of refrigerators is not only bad for the environment, but it is also against the law. In many countries, there are laws and regulations in place to ensure that refrigerators are disposed of properly. These laws are designed to protect the environment and human health.

**The Steps Involved in Properly Disposing of Refrigerators**

1. Recycle: Refrigerators can be recycled, which means that the materials used to make them can be reused. This helps to reduce waste and conserve natural resources.

2. Retire: If your refrigerator is still in good condition, you may be able to donate it to a local charity or organization. This helps those in need while also reducing waste.

3. Dispose of properly: If your refrigerator is no longer usable, it must be disposed of properly. This means taking it to a designated waste facility where it can be handled safely and responsibly.

**Conclusion**

Proper disposal of refrigerators is important for both the environment and human health. By following the steps outlined above, we can ensure that our old refrigerators are disposed of in a way that is safe and responsible. By doing so, we can help to protect the planet and future generations.

Lesson: Common Fixed Points in Complex Valued Metric Spaces

Introduction:
In mathematics, a common fixed point is a point that is fixed by two or more mappings. In this lesson, we will study common fixed points in complex valued metric spaces and obtain sufficient conditions for their existence.

Section 1: Theoretical Concepts

1.1 What is a common fixed point?
A common fixed point is a point x* that satisfies the equations x* = T(x*) and x* = S(x*), where T and S are mappings from a set X to itself.

1.2 What is a complex valued metric space?
A complex valued metric space is a pair (X, d), where X is a set of elements and d is a function that measures the distance between any two elements in X.

1.3 What is a contractive type mapping?
A contractive type mapping is a mapping that satisfies the contraction condition, which means that there exists a constant M such that for any two distinct points x and y in X, the distance between their images under the mapping is less than the distance between them, i.e., d(T(x), T(y)) < d(x, y) - M.

Section 2: Practical Examples

2.1 Let's consider a complex valued metric space X = {a, b} with the metric d(x, y) = |x - y|. Let T(x) = x + 1 and S(x) = x + 2. Find the common fixed point of T and S.

Solution:
Substituting x* into the equations, we get:
x* = T(x*) + 1 and x* = S(x*) + 2

Adding the two equations, we get:
2x* = x* + 3

Rearranging the equation, we get:
x* = 3

Since there is no complex valued metric space with two elements and the given mappings, we cannot find a common fixed point in this case.

Section 3: Self-Debating Discussions

3.1 Why is the concept of common fixed points important in mathematics?
The concept of common fixed points is important in mathematics because it is used to solve a variety of problems in different fields, such as economics, game theory, and optimization.

3.2 How does the contraction condition relate to the existence of common fixed points?
The contraction condition is a necessary and sufficient condition for the existence of a common fixed point for a pair of mappings. If a mapping satisfies the contraction condition, then it has a unique common fixed point, which can be found using Banach's theorem.

Conclusion:
In this lesson, we studied common fixed points in complex valued metric spaces and obtained sufficient conditions for their existence. We also saw how the contraction condition relates to the existence of common fixed points and applied the concept to a practical example. By understanding the concepts and techniques presented in this lesson, students can apply them to new problems and gain a deeper understanding of mathematics.

Glossary:
- Common fixed point: A point that is fixed by two or more mappings.
- Complex valued metric space: A pair (X, d) where X is a set of elements and d is a function that measures the distance between any two elements in X.
- Contractive type mapping: A mapping that satisfies the contraction condition, which means that there exists a constant M such that for any two distinct points x and y in X, the distance between their images under the mapping is less than the distance between them.

The basic method in common use involves chemically collapsing a filter made of cellulose ester membrane onto a glass microscope slide to provide a clear background aginst which to count the individual fibers with the aid of an optical microscope. Until recently, a method recommended by National Institute of Occupational Safety and Health (NIOSH) for accomplishing the filter clearing is to use a stream of acetone vapor which is produced by heating liquid acetone to a temperature of about 56.degree. C. The stream of acetone vapor used for clearing must be capable of rapidly collapsing the filter structure without distorting the filter or displacing the dust on the filter. Fire hazards associated with the use of acetone vapor are substantial and have restricted general use of this clearing technique without specialized equipment designed to reduce the likelihood of fire.
In the aforementioned procedure a flask of acetone is heated to cause vapor formation by continuous boiling. Ducting a vapor stream in a downward direction allows a sampling of cellulose ester filter to be positioned under the vapor stream to effect the clearing procedure. This technique makes inefficient use of acetone and poses a substantial fire hazard thus limiting its use to a ventilated fume hood.
Based on an improvement of the above method, two acetone vaporizers designed for asbestos air sample preparations have been marketed by BGI Incorporated of Waltham, MA and ETC of Monroeville, PA. These vaporizers are stated to be usable in unventilated areas and one is accompanied by an auxiliary heater that is in a separate housing. The heater has surfaces heated to about 50.degree. C. on which a slide can be placed to complete the clearing process if necessary.
In a Revision #2 of the NIOSH Method #7400 dated Aug. 15, 1987, an aluminum "hot block" technique was recommended. This apparatus is shown in FIG. 1 of the drawings and is described in a article entitled "An Asbestos Sample Filter Clearing Procedure", by Baron, et al.
In this prior art procedure, a portion of the circular filter, usually 90.degree. segment, has been cut and placed on a glass slide. Acetone vapors directed to the filter segment cause the cellulose ester material to clear and become essentially invisible in a period of about 5 seconds. The vapors are directed as a plume rather than as a point source so condensation occurs over the entire surface of the filter, thereby minimizing shrinkage and distortion. As in the earlier NIOSH Method #7400, one or two drops of triacetin are placed on the treated filter wedge. A glass cover slide is put over it and the edges are sealed with lacquer or nail polish to create a permanent mount.
With the FIG. 1 equipment, flash vaporization of acetone is made possible and thus the need no longer exists for continuous boiling of a quantity of acetone in a flask which was an earlier prior practice. A unitary block 10 of aluminum is heated by a suitable means such as heating pads on opposite side walls to a temperature of about 70.degree. C. as detected by a surface thermometer 12. A blind hole 14 having a diameter of about 2.5 cm is drilled from an upper surface 16, which serves as a flash vaporization chamber, and a similar blind hole 18 is drilled from the bottom or lower surface 20 which serves as a condensation chamber 18. A horizontal connecting channel 22 is drilled from a side face 23 to interconnect the holes 14 and 18. Hole 22 is plugged as by a threaded set screw 24 to prevent vapor escape. A recess having walls 26 is machined across the bottom surface 20 to provide a notch to allow a slide 28 to be inserted over the upper surface of an unheated ceramic base 29. The filter segment is intended to be centrally located under the hole 18.
An insulating plug 30 of a synthetic resin material such as Teflon a polytetrafluoroethylene, with a small passageway 32 allows the insertion of the tip of an adjustable micropipette. Acetone liquid at ambient temperature is injected into the flash vaporization chamber 14 directly below plug 30. Acetone vapor is directed along horizontal channel 22 to hole 18 where it is directed downwardly to condense on the filter and slide surfaces. The ducting has no direct path for liquid to reach the filter. The vapor is allowed to expand and diffuse along duct 22 so that the filter is exposed to a uniform plume of acetone vapor.
In operation, the metal block 10 is placed on a smooth surface 29 usually of ceramic where the block 10 remains during the time when a number of filter segments that have been placed on separate glass slides 28 are sequentially inserted under the condensation chamber 18 where the vapor is directed downwardly. Upon removal of each slide, a drop of triacetin is applied to the center of the cleared filter and a glass coverslip is applied. Complete clearing of the filter sometimes requires an additional time which may be reduced to 15 minutes or less if placed on a surface heated to no more than about 50.degree. C.
One problem with using the FIG. 1 device is that the filter material is very light and when placed on a glass slide 28 is influenced by electrostatic forces. Moving the slide 28 along the surface of ceramic base 29 into the slot having walls 26 under the heated block 10 is frequently accompanied by a displacement of the filter from the desired position in the center of the chamber 18. Visual observation of the final position of the filter on slide 28 is not possible.
Another problem is that over prolonged period of operation, latent heat builds up in that portion of ceramic base 29 that underlies block 10 which decreases the rate of condensation of acetone and hence the uniformity of the action of the vapor to clear the cellulose ester filter material.

Lesson: How to Clear a Filter for Microscopy

### Introduction

Microscopy is a technique used to examine small objects or materials that cannot be seen with the naked eye. One of the most common methods of clearing a filter for microscopy is using acetone vapor. This method is simple, fast, and effective, but it comes with some risks, such as fire hazards. In this lesson, we will learn how to clear a filter for microscopy using acetone vapor safely and effectively.

### Section 1: Theory

1.1 What is microscopy?
Microscopy is a technique used to examine small objects or materials that cannot be seen with the naked eye. It uses magnifying glasses, lenses, or cameras to enlarge images of objects.

1.2 Why do we need to clear a filter for microscopy?
Filters are used to separate particles from air samples. When we want to examine these particles under a microscope, we need to clear the filter so that we can see the individual fibers clearly.

1.3 How does acetone vapor clear a filter?
Acetone is a solvent that dissolves cellulose ester, which is the material used to make filters. When we heat acetone to a certain temperature, it produces vapor that can collapse the filter structure, allowing us to see the individual fibers clearly.

### Section 2: Practice

2.1 How to clear a filter using acetone vapor
1. Place a filter on a glass microscope slide.
2. Heat acetone to a temperature of about 56°C.
3. Direct a stream of acetone vapor at the filter.
4. Observe the filter under a microscope to ensure that it is cleared.

2.2 Safety precautions
1. Use a fume hood when working with acetone vapor to avoid inhalation of toxic fumes.
2. Do not use an open flame to heat the acetone, as it is highly flammable.
3. Wear gloves and safety goggles to protect your skin and eyes from the acetone.
