Quote I have a dream that one day this nation will rise up and live out the true meaning of its creed: ‘We hold these truths to be self-evident, that all men are created equal.’

Monday, January 20, 2020, marks America’s 35th celebration of Martin Luther King, Jr., Day. Honoring King with the sacred status of a federal holiday—of which there are only 10, none other named for a 20th-century figure—is a testament to the unifying power of his legacy.

King’s most important work applied America’s Founding ideals to the cause of civil rights. The last best hope for true racial progress, King realized, was solidarity: For people to see and treat one another as equals, they had to feel the tugs of a bond far stronger than either race or politics.

For King, that bond was America.

After all, there are two words in the phrase “civil rights”—and King grasped that both are crucial. Civil rights are about the fair and equal participation of all citizens in the American community. For those rights to have any power, the bonds of that community must be close-knit and resilient.

Quote America's promise of freedom and justice has guided our people through adversity to prosperity. Dr. King's life and legacy stands as a testament to that promise, one rooted in the inalienable rights of mankind and a commitment to freedom from persecution.

King’s greatest legacy is helping secure those rights while strengthening our national idea, not undermining it. He understood that so much of our country’s racial history, from the Civil War to the Voting Rights Act of 1965, was not a rejection of American values. To the contrary, these episodes were parts of a long struggle to live up to our Founding ideals of equality, liberty, and democracy.

“I criticize America because I love her,” King said in a speech about the Vietnam War, “and because I want to see her to stand as the moral example of the world.”

For those reasons and more, King’s story is worth remembering. President Donald J. Trump wants to ensure that legacy lives on for generations of Americans. In January 2018, he signed H.R. 267 into law. Named the “Martin Luther King, Jr. National Historical Park Act,” the law redesignates a National Historic Site in Georgia—the state where King was born—as the Martin Luther King, Jr. National Historical Park.

President Donald J. Trump hands a pen to Isaac Newton Farris Jr., a nephew of slain Civil Rights leader Dr. Martin Luther King, Jr., after signing a proclamation in honor of Martin Luther King, Jr., Day.

This year, the President signed a proclamation on January 17 that officially designated the following Monday as the “Martin Luther King, Jr., Federal Holiday.”

Conservatives and liberals alike can learn from King’s example. “In the United States of America, every citizen should have the opportunity to build a better and brighter future,” President Trump’s proclamation from 2019 reads. “United as one American family, we will not rest — and we will never be satisfied — until the promise of this great Nation is accessible to each American in each new generation.”

The past few years have been especially important in our work to live up to Dr. King’s dream. As 2018 came to a close, President Trump signed the historic, bipartisan First Step Act into a law. First Step prepares inmates to successfully rejoin society, and it enacts commonsense reforms that will make our justice system fairer for all Americans.

In 2019, President Trump built on that success by promoting second-chance hiring—an opportunity for Americans to live with dignity and meaning after they serve their time. The President mobilized resources across his Administration and worked with the private and non-profit sectors to help give former prisoners a second chance at the American Dream.

The premise—and promise—of King’s dream is that we don’t need to replace or transform our Nation’s shared ideals to make our country a better place.

We simply need to live up to them.

Lesson: The Importance of Equality in America

### Overview

In this lesson, we will explore the concept of equality in America, as discussed by Martin Luther King Jr. We will analyze his famous quote, "I have a dream that one day this nation will rise up and live out the true meaning of its creed: 'We hold these truths to be self-evident, that all men are created equal.'" We will also examine how King's vision of equality has influenced America's civil rights movement.

### Section 1: Introduction

Equality is a fundamental principle of the United States. It means that all people are created equal, regardless of their race, gender, religion, or any other factor. This principle is enshrined in the Constitution and has been a guiding force in American society since the country's founding. In this lesson, we will explore the importance of equality in America, as discussed by Martin Luther King Jr.

### Section 2: The Concept of Equality

Equality is the idea that all people should be treated fairly and equally, regardless of their background or circumstances. This concept is central to the American Dream, which holds that anyone can achieve success through hard work and dedication. However, achieving equality is not always easy, as it often requires challenging entrenched social and economic systems that favor certain groups over others.

### Section 3: The Civil Rights Movement

The civil rights movement was a mass protest movement against the American South's policy of racial segregation in the 1950s and 1960s. The movement aimed to end the practice of "separate but equal" facilities for blacks and whites, and to ensure equal protection under the law for all citizens. Martin Luther King Jr. was a key leader in the civil rights movement, and his vision of equality played a crucial role in shaping its goals and strategies.

### Section 4: The Legacy of Martin Luther King Jr.

Martin Luther King Jr.'s vision of equality continues to inspire people around the world today. His famous quote, "I have a dream that one day this nation will rise up and live out the true meaning of its creed: 'We hold these truths to be self-evident, that all men are created equal,'" remains a powerful statement of America's founding principles. King's legacy reminds us of the importance of fighting for equality, even in the face of great opposition.

### Section 5: Conclusion

Equality is a fundamental principle of the United States, and it is essential that we continue to work towards achieving it. As Martin Luther King Jr. said, "We must learn to live together as brothers or perish together as fools." By striving for equality, we can create a more just and equitable society for all Americans.

Lesson: Introduction to Patents

**Objective:** To understand the basics of patents and their importance in protecting intellectual property.

**Glossary:**
- Patent: A legal document granted by a government to an inventor or assignee for a new, useful, and non-obvious invention.
- Intellectual Property: Any creation of the mind, such as an idea, design, or invention, that can be legally protected.

**Lesson:**

**Section 1: What is a Patent?**

A patent is a legal document granted by a government to an inventor or assignee for a new, useful, and non-obvious invention. It provides the owner with exclusive rights to make, use, and sell the invention for a certain period of time, usually 20 years.

**Section 2: Why are Patents Important?**

Patents are important because they protect intellectual property from being copied or stolen by others. This encourages innovation and creativity, as inventors and businesses can profit from their ideas without fear of competition. Patents also provide a way for inventors to share their knowledge with the public, as the details of the invention must be disclosed in the patent application.

**Section 3: How do you get a Patent?**

To get a patent, an inventor must file a patent application with the relevant patent office. The application must include a detailed description of the invention, its advantages, and how it works. The patent office will then review the application to determine if the invention is new, useful, and non-obvious. If the application is approved, the inventor will be granted a patent.

**Section 4: Example**

Let's say you invented a new type of car engine that is more efficient and environmentally friendly than existing engines. You would file a patent application with the patent office, describing your invention in detail. Once approved, you would be granted a patent, giving you exclusive rights to make, use, and sell your invention for 20 years.

**Section 5: Conclusion**

Patents are an important tool for protecting intellectual property and encouraging innovation. By understanding the basics of patents, you can appreciate their significance in promoting creativity and entrepreneurship.

Lesson: Designing a Pedestrian Bridge

## Introduction
In this lesson, we will learn about designing a pedestrian bridge. We will explore the concept of a parkway extension and the materials used to construct it. We will also examine the location of the proposed bridge and its publicity. Finally, we will analyze the design completion and the benefits of such a structure.

## Section 1: Theoretical Concepts

**Purpose of a Pedestrian Bridge:** A pedestrian bridge is a structure built to provide safe passage for people walking or traveling on foot. It is often constructed over obstacles such as roads, rivers, or railways to connect two points that would otherwise be difficult to reach.

**Design Elements:** The design of a pedestrian bridge should consider several elements, including the following:

- **Safety:** The bridge must be designed with safety in mind. It should have a low risk of collapse, be stable, and have guardrails or other safety features to prevent falls.
- **Aesthetics:** The bridge should be visually appealing and blend in with the surrounding environment. It should also reflect the culture and history of the area where it is located.
- **Functionality:** The bridge should serve its intended purpose effectively. It should be able to handle the expected load and provide easy access for pedestrians.
- **Durability:** The bridge should be built to last and withstand the elements, including wind, rain, and temperature changes.

## Section 2: Practical Examples

**Loop Stitch Bridge:** The Loop Stitch Bridge was a proposal for a pedestrian bridge addition to a historical auto bridge in Pittsburgh. The original bridge was the 'end' bridge of a series that connected parkway systems along both sides of the main river. This pedestrian bridge addition 'stitched' together the park areas flanking the river, making a 'loop' to direct people back toward the city.

**Materials Used:** The Loop Stitch Bridge was made of steel, concrete, and fabric. These materials were chosen for their strength, durability, and ability to withstand the elements.

**Location:** The bridge was located in Pittsburgh, Pennsylvania, and spanned across the Allegheny River. It was designed to connect the North Shore trail system to the riverfront park system, creating a continuous loop for pedestrians and cyclists.

**Publicity:** The Loop Stitch Bridge was featured in the Riverlife Bridge Competition, which showcased innovative designs for bridges in Pittsburgh. The bridge also received funding from the Alcoa Foundation, which supported its construction and exhibition.

**Design Completion:** The Loop Stitch Bridge was completed in 2005, providing a safe and beautiful passage for pedestrians over the Allegheny River.

## Section 3: Self-Debating Discussions

**Benefits of Pedestrian Bridges:** Pedestrian bridges offer several benefits, including the following:

- **Promotion of Pedestrian Traffic:** By providing safe and convenient passage for pedestrians, bridges encourage people to walk instead of drive, reducing traffic congestion and air pollution.
- **Urban Fabric Metaphor:** Pedestrian bridges can serve as a metaphor for the urban fabric, connecting different parts of a city and promoting social interaction.
- **Extension of Urban Parkway Systems:** Pedestrian bridges can extend parkway systems, providing access to green spaces and recreational opportunities for people who may not otherwise have access to them.
- **Creation of Viewscapes:** Pedestrian bridges can create viewscapes, allowing people to appreciate the beauty of their surroundings while traversing the bridge.
- **Operable Shading Features:** Some pedestrian bridges have operable shading features that can be adjusted to provide shade or allow sunlight to pass through, depending on the weather conditions.

## Glossary
- **Parkway:** A landscaped roadway with open spaces on either side.
- **Urban Fabric:** The physical structure and organization of a city, including its buildings, streets, and public spaces.
- **Viewscapes:** Scenic views of natural or man-made landscapes.

## Conclusion
In conclusion, pedestrian bridges are an essential component of urban design, providing safe and convenient passage for people on foot. By promoting pedestrian traffic, serving as a metaphor for the urban fabric, extending parkway systems, creating viewscapes, and offering operable shading features, pedestrian bridges enhance the quality of life for city dwellers. By studying the design and implementation of the Loop Stitch Bridge, we can gain valuable insights into the process of designing a successful pedestrian bridge.

1. Technical Field
The present invention is directed to apparatus and methods for co-location and off-loading of web site traffic based on traffic pattern recognition. More specifically, the present invention is directed to apparatus and methods for profiling web sites, determining which web sites should be co-located and when offloading of web traffic to other servers should be performed.
2. Description of Related Art
With the increasing popularity of the Internet and its applications, the allocation of resources in order to provide a Quality of Service (QoS) has become more difficult. The complexity of the problem of resource allocation is exacerbated by the heterogeneity of the Internet infrastructure and applications as well as the user behaviors.
One approach to the resource allocation problem is to share resources, such as web servers, among multiple entities, such as web sites, so that peak load conditions for any given entity can be handled by borrowing resources from other entities. Such a mechanism is often referred to as co-location. An important problem in this paradigm is concerned with the clustering of the web sites for the resource sharing. That is, it is often difficult and imprecise manual process to identify which web sites should share resources.
Another approach, which is complementary to co-location, consists of offloading work for an entity to exogenous resources in a dynamic way. With offloading, web site traffic that is destined for a particular web server that is currently in an overloaded state is redirected to another server to handle the processing of the traffic. A key problem with offloading is determining where and when to offload the work. The known mechanisms for determining where and when to offload work typically fall into the area of load balancing where current state information is used to determine if the work load should be balanced by sending some of the work to other servers. Such work load balancing mechanisms are reactionary and do not make use of known patterns of traffic to begin offloading prior to the servers becoming overloaded.
Thus, it would be beneficial to have an improved apparatus and method for determining which web sites should be co-located and when traffic to web sites should be offloaded to other web servers.

text: Limited proteolysis of bacteriophage T7 primase/helicase with endoproteinase Glu-C produces several proteolytic fragments. One of these fragments, which is derived from the C-terminal region of the protein, was prepared and shown to retain helicase activity. This result supports a model in which the gene 4 proteins consist of functionally separable domains. Crystals of this C-terminal fragment of the protein have been obtained that are suitable for X-ray diffraction studies.

textbook:
Lesson: Protein Fragments and their Functions

**Introduction:** In this lesson, we will learn about protein fragments and their functions. We will use the example of bacteriophage T7 primase/helicase to understand how proteins can be broken down into smaller parts and still retain their functionality.

**Section 1: Protein Fragments**

A protein is made up of amino acids linked together by peptide bonds. Sometimes, scientists need to study a protein's structure or function, but working with the whole protein can be difficult. To overcome this challenge, they can break the protein down into smaller pieces called protein fragments. These fragments can still have the same function as the original protein, even though they are not whole proteins.

**Section 2: Bacteriophage T7 Primase/Helicase**

Bacteriophage T7 is a virus that infects bacteria. It has a protein called primase/helicase, which is essential for its life cycle. This protein has two functions: it helps replicate the viral DNA and also unwinds the DNA double helix.

**Section 3: Limited Proteolysis**

In a process called proteolysis, scientists use enzymes to break proteins down into smaller fragments. In the case of bacteriophage T7 primase/helicase, researchers used a specific enzyme called endoproteinase Glu-C to break the protein into smaller pieces.

**Section 4: Functional Domains**

When the researchers analyzed the smaller fragments produced by proteolysis, they found that one of them, derived from the C-terminal region of the protein, still had helicase activity. This means that this fragment could unwind DNA just like the original primase/helicase protein. This result supports the idea that proteins can have functionally separate domains.

**Section 5: Crystal Structures**

To learn more about the structure of the C-terminal fragment, scientists grew crystals of this protein fragment that were suitable for X-ray diffraction studies. By studying these crystals, they can learn more about the structure of this protein fragment and how it interacts with other molecules.

**Conclusion:** In this lesson, we learned about protein fragments and how they can still have the same function as the original protein. We used the example of bacteriophage T7 primase/helicase to show how limited proteolysis can help scientists study proteins and their functions. By analyzing the smaller fragments produced by proteolysis, researchers can gain insights into the structure and function of proteins, which can ultimately lead to new discoveries and applications in fields such as medicine and biotechnology.

Making seemingly-unrelated changes (e.g. changing the _::_ pattern to _) allows it to be type checked successfully. Asking merlin for the type of [x] and then adding that, as [let f (x:[ `A ] Element.t) = ...], also allows it to pass.

the GADT code is triggered even for ordinary constructors. The pull request notes:

(* There are various things that we need to do in presence of GADT constructors
that aren't required if there are none.
However, because of disambiguation, we can't know for sure whether the
patterns contain some GADT constructors. So we conservatively assume that
any constructor might be a GADT constructor. *)

So it looks like there's a longstanding bug in the GADT path (since code accepted with -principal should usually also be accepted without -principal), and in 4.07.0 the GADT path is now taken more frequently, causing new failures in existing code.

Lesson: Understanding Type Checking in Programming Languages

Introduction:
Type checking is an essential part of programming languages that helps ensure that the code written by programmers is correct and error-free. It involves checking the types of values and variables used in a program to ensure that they match. In this lesson, we will learn about type checking, its importance, and how it works in different programming languages.

Section 1: What is Type Checking?
Type checking is the process of verifying that the types of expressions in a program are correct. It is an essential part of programming languages because it helps catch errors before they become significant problems. Type checking ensures that values and variables used in a program are of the correct data type, preventing unexpected behavior and crashes.

Section 2: Importance of Type Checking
Type checking is crucial for several reasons:

1. Error Prevention: Type checking helps catch errors before they become significant problems, saving time and effort in debugging.

2. Readability: Type checking makes code more readable and understandable, as developers can easily see the data types of values and variables.

3. Security: Type checking helps prevent security vulnerabilities by ensuring that values and variables are of the correct data type, preventing attacks such as buffer overflows and type confusion errors.

4. Performance: Type checking helps optimize performance by ensuring that values and variables are of the correct data type, preventing runtime errors and crashes.

Section 3: How Type Checking Works
Type checking works differently in various programming languages, but the general idea remains the same: check the types of values and variables used in a program to ensure that they match. Here are some ways type checking works in different programming languages:

1. Static Typing: In statically typed languages like C, Java, and C++, type checking occurs at compile-time, where the compiler checks the types of values and variables used in a program and issues an error if they don't match.

2. Dynamically Typed: In dynamically typed languages like Python and JavaScript, type checking occurs at runtime, where the interpreter checks the types of values and variables used in a program as the code runs.

3. Gradually Typed: In gradually typed languages like TypeScript, type checking is a combination of static and dynamic typing, where the type checker tries to infer the types of values and variables at compile-time but allows for some type errors at runtime.

Section 4: Practical Examples
Let's look at some practical examples of type checking in action:

Example 1: In the following code snippet, the variable "age" is assigned an integer value, but it is used in a string context, leading to a TypeError:

```python
age = 25
name = "John"
print("The age of", name, "is", age)
```

In this example, the type checker detects that the value of "age" is an integer, while the context requires a string. Therefore, a TypeError is raised when the program is executed.

Example 2: In the following code snippet, the variable "num" is assigned a float value, but it is used in an integer context, leading to an OverflowError:

```python
num = 10.5
for i in range(num):
    print(i)
```

In this example, the type checker detects that the value of "num" is a float, while the context requires an integer. Therefore, an OverflowError is raised when the program is executed.

Conclusion:
In this lesson, we learned about type checking, its importance, and how it works in different programming languages. We also looked at some practical examples of type checking in action. By understanding type checking, we can write more robust and error-free code, ensuring that our programs run smoothly and efficiently.

The control of undesired vegetation is extremely important in achieving high crop efficiency. Achievement of selective control of the growth of weeds especially in such useful crops as rice, soybeans, sugar beets, corn, potatoes, wheat, barley, tomatoes and plantation crops among others is very desirable. Unchecked weed growth in such useful crops can cause significant reduction in productivity and thereby result in increased costs to the consumers. The control of undesired vegetation in noncrop areas is also important. The need for finding products that achieve such results continues to be commercially important.
U.S. Pat. No. 5,090,993 discloses triflusulfuron methyl and describes its utility for selective weed control in sugar beets. U.S. Pat. Nos. 4,315,765 and 4,405,531 disclose herbicidal salts of glyphosate. WIPO publications WO 92/00377, WO 92/04449, WO 92/06201 and WO 92/19719 and U.S. Pat. Nos. 4,940,835, 4,971,908, 5,188,642 and 5,310,667 disclose methods for genetically transforming sugar beets to make them resistant to glyphosate. None of these references disclose the mixtures of this invention.

Lesson: Introduction to Herbicides

## Section 1: Theoretical Concepts

Herbicides are chemicals used to control undesired vegetation. They are essential in agriculture to increase crop yield and quality. There are two main types of herbicides: selective and non-selective. Selective herbicides target specific plants, while non-selective herbicides affect all plants.

## Section 2: Practical Examples

One example of a selective herbicide is glyphosate, which is used to control weeds in crops like sugar beets, soybeans, and corn. It works by inhibiting the enzyme that produces amino acids in the plant, leading to its death. Another example is 2,4-D, which selectively controls broadleaf weeds in lawns and pastures without affecting grasses.

## Section 3: Real-World Scenarios

Non-selective herbicides like Roundup are used to control weeds in non-crop areas like roadsides, parks, and golf courses. They work by killing both desired and undesired plants. However, they can also harm beneficial plants and animals, so they must be used carefully.

## Glossary

- Herbicide: A chemical used to control undesired vegetation
- Selective herbicide: A herbicide that targets specific plants
- Non-selective herbicide: A herbicide that affects all plants
- Glyphosate: A selective herbicide used in crops like sugar beets, soybeans, and corn
- 2,4-D: A selective herbicide used to control broadleaf weeds
- Roundup: A non-selective herbicide used in non-crop areas

## Conclusion

Herbicides are essential in agriculture to increase crop yield and quality. Selective herbicides target specific plants, while non-selective herbicides affect all plants. It is crucial to use herbicides carefully to avoid harming beneficial plants and animals. Understanding the different types of herbicides and their uses is essential for anyone interested in agriculture or horticulture.

Lesson: Introduction to Contemporary Craft

## Section 1: What is Contemporary Craft?

Contemporary craft refers to the creation of artistic objects that are handmade or machine-made using traditional craft techniques such as weaving, knitting, pottery, and woodworking. It encompasses a wide range of materials and techniques, including both functional and non-functional objects.

### Questions and Answers:

**Question:** What is the difference between contemporary craft and fine art?
**Answer:** Contemporary craft and fine art are two separate but related fields. While fine art often focuses on creating unique, one-of-a-kind pieces that are meant to be displayed in a gallery, contemporary craft often involves the use of traditional techniques to create functional objects.

A statement on the deal released Friday said “the agreement entails the sale of the cable TV and broadband internet assets and subscribers of DCI, SBC, and UNI to SKY.”

“The pay TV and broadband markets require continuous significant investments, if we are to keep up with our major competitors, particularly the direct-to-home satellite (DTH) and telco companies,” said David Lim, president of DCI, SBC, and UNI.

Lim said the agreement was reached order to give their Destiny Cable and MyDestiny broadband subscribers “the best products and services possible.”

To do this, Lim said they “realized that this will entail resources, for digitizing our cable network and expanding our broadband services, that we do not have.”

“We believe our agreement with SKY will allow subscribers to enjoy the benefits of the latest technologies," Lim said.

He said SKY “will take extra care not to disrupt the existing services of the current subscribers – they will continue to pay same monthly fees for their subscribed plans, at the same payment centers, and can continue to reach Customer Service at the same numbers. We will make announcements on new services to be made available, at the appropriate time.”

Lim said the deal will allow their holding company, Solid Group Inc., to focus on selling its mobile phone brand, MyPhone.

“Our tie up with SKY came at an opportune time as it allows us to focus on our other core businesses. Our holding company Solid Group Inc (SGI), markets and distributes the leading Filipino mobile phone brand MyPhone," he said.

ABS-CBN Corp.'s Sky Cable is the Philippines’ largest cable television service provider with around 500,000 upscale subscribers in Metro Manila and key urban areas nationwide.

MANILA, Philippines - Sky Cable Corp. on Monday said it would borrow money to finance the acquisition of Destiny Cable Inc. and its two affiliates.

In a disclosure to the Philippine Stock Exchange, ABS-CBN Corp., the parent company of Sky Cable, said it will use both equity and borrowed funds to finance the purchase of the assets of Destiny Cable, Solid Broadband Corp. and Uni-Cable TV Inc. for P3.5 billion.

Under the asset purchase agreement, Sky Cable, a subsidiary of Sky Vision Corp., will purchase all Destiny Cable assets for P2.4 billion.

The Lopez-owned Sky Cable also will acquire Solid Broadband for P1 billion and Uni-Cable for P93.6 million.

In a separate disclosure, Solid Group Inc. said the sale of its cable TV and broadband Internet assets would allow the company to focus on its evolving new businesses in the fields of wireless digital devices and technologies and other projects. The Solid Group also manufacturers and markets the myPhone brand of mobile phones.

Now that Sky buys Global Destiny, is there a possibility to that GNN will be ceased it's broadcast and replace it with ANC to all Global Destiny Subscribers?
And since Global Destiny has it's own Satellite service G-Sat, Is there a possibility that SkyCable will also make business in the Satellite Industry?

Lesson: Acquisition and Merger in Business

Introduction:
In business, acquisition and merger are common strategies used by companies to expand their reach, increase their revenue, and improve their services. In this lesson, we will learn about the process of acquisition and merger, the reasons behind them, and the impact on the customers and employees of the involved companies.

Section 1: What is Acquisition and Merger?
Acquisition and merger are two ways that companies can combine their operations to create a more efficient and profitable business. Acquisition refers to the purchase of one company by another, while merger refers to the combination of two or more companies into a single entity.

Section 2: Reasons for Acquisition and Merger
There are several reasons why companies choose to acquire or merge with another company. These reasons include:

1. Expansion: Companies may want to expand their reach and offerings by acquiring or merging with another company that has complementary products or services.

2. Cost savings: By combining operations, companies can reduce costs and improve efficiency, leading to increased profitability.

3. Synergy: Acquiring or merging with another company can create synergies, where the combined entity is worth more than the sum of its parts.

4. Strategic fit: Companies may want to acquire or merge with another company to gain access to new markets, technologies, or expertise.

Section 3: Impact on Customers and Employees
When two companies merge or one company acquires another, there can be significant changes for both customers and employees.

1. Customers: Customers may experience changes in products, services, pricing, and customer service. They may also need to adapt to new systems or processes.

2. Employees: Employees may experience changes in their job responsibilities, work environment, and management structure. Some employees may be laid off or offered new positions, while others may stay with the company but see changes in their job duties.

Section 4: Conclusion
Acquisition and merger are important strategies for companies looking to grow and improve their business. While these transactions can have significant impacts on customers and employees, they can also lead to increased efficiency, cost savings, and new opportunities. By understanding the reasons behind these transactions and the changes that may occur, customers and employees can navigate the transition more effectively.

Glossary:
- Acquisition: The purchase of one company by another
- Merger: The combination of two or more companies into a single entity
- Synergy: The combined value of two or more entities working together
- Strategic fit: The alignment of two companies' products, services, or expertise

Self-Debating Discussion:
1. Why do you think companies choose to acquire or merge with another company?
2. How do you think customers and employees are affected by acquisition and merger?
3. Can you think of any examples of successful acquisitions or mergers in recent years? Why do you think they were successful?


text: Graduate Financial Aid. Financial aid programs were developed by the federal and state governments as well as by institutions of higher education to assist students from families with limited resources to meet educational expenses. The primary purpose of financial aid is to ensure that no one is denied the opportunity of a college education because of financial need.. When applying for financial aid at The University of Akron, the Office of Student Financial Aid determines a budget that best suits the needs of the student. The budget includes direct costs that must be paid to the University (i.e., instructional and general fees and room and board in the residence halls) and variable expenses such as transportation and personal expenses.

Lesson: Understanding Financial Aid

**Introduction:** Financial aid is an essential aspect of higher education, providing students with the necessary funds to pursue their dreams of obtaining a college degree. This lesson will provide a comprehensive understanding of financial aid, its purpose, and how it works.

**Section 1: What is Financial Aid?**

Financial aid refers to any form of funding that helps students pay for their education. It can come in the form of grants, scholarships, loans, or work-study programs. The primary purpose of financial aid is to ensure that no one is denied the opportunity of a college education because of financial need.

**Section 2: Types of Financial Aid**

There are several types of financial aid available to students, including:

1. Grants: Grants are a type of gift aid that does not have to be repaid. They are usually awarded based on financial need.

2. Scholarships: Scholarships are also a type of gift aid that does not have to be repaid. They are usually awarded based on merit, such as academic achievement or talent in a particular area.

3. Loans: Loans are a type of financial aid that must be repaid, along with interest. There are two types of loans: subsidized and unsubsidized. Subsidized loans are based on financial need and do not accrue interest while the student is in school. Unsubsidized loans accrue interest from the day they are disbursed.

4. Work-Study Programs: Work-study programs provide students with part-time employment opportunities to help them pay for their education. The amount earned through these programs does not have to be repaid.

**Section 3: How to Apply for Financial Aid**

To apply for financial aid, students must complete the Free Application for Federal Student Aid (FAFSA). The FAFSA is used to determine a student's financial need and eligibility for financial aid. It is recommended that students submit their FAFSA as early as possible to maximize their chances of receiving financial aid.

**Section 4: Budgeting for Financial Aid**

When applying for financial aid at The University of Akron, the Office of Student Financial Aid determines a budget that best suits the needs of the student. The budget includes direct costs that must be paid to the University (i.e., instructional and general fees and room and board in the residence halls) and variable expenses such as transportation and personal expenses.

**Section 5: Conclusion**

Financial aid plays a crucial role in ensuring that higher education is accessible to all students, regardless of their financial situation. By understanding the different types of financial aid, how to apply for financial aid, and how to budget for financial aid, students can make informed decisions about their education and future.

Would have been nice if the ordering site mentioned this (but then no other site selling U Bolts makes that distinction either).. Richard Hubert –

textbook:
Lesson: Introduction to U-Bolts

## Section 1: Theoretical Concepts
A U-bolt is a type of bolt with a looped shape that is commonly used in construction and engineering applications. It is designed to provide a strong and secure connection between two objects, such as beams or columns. In this lesson, we will learn about the different types of U-bolts, their properties, and how they are used in various industries.

## Section 2: Practical Examples
U-bolts come in different sizes and shapes, depending on their intended use. For example, a 5/8-inch diameter semi-round U-bolt is typically used in automotive applications to connect the frame to the body or suspension components. These bolts have a curved shape that allows them to fit snugly against the surface of the object they are connecting.

To understand how U-bolts work, let's consider a simple example. Suppose you need to attach a beam to a column in a building. You would use a U-bolt to connect the two objects. The loop of the U-bolt would fit around the column, and the bolt would be tightened to create a secure connection. This type of connection is known as a "lift" connection because it lifts the beam off the ground, allowing for free movement.

## Section 3: Real-World Scenarios
Now let's consider a more complex scenario. Imagine you are working on a construction site and need to connect a large piece of machinery to a concrete foundation. You would use a heavy-duty U-bolt to secure the machine in place. These bolts are made of strong materials like steel and can support a lot of weight.

To determine the right size and type of U-bolt for your application, you would need to consider several factors, including the weight of the object being connected, the material of the objects, and the environmental conditions. For example, if you were connecting a metal object in a humid environment, you would need to choose a U-bolt that resists corrosion.

## Conclusion
In this lesson, we have learned about U-bolts, their properties, and how they are used in various industries. We have also considered real-world scenarios where U-bolts are used to secure objects in place. By understanding the principles behind U-bolts, we can apply this knowledge to new problems and find innovative solutions.

CSF neurofilament and soluble TNF receptor 1 levels in subacute sclerosing panencephalitis.
Neurofilament (NF) is one of the major cytoskeleton proteins of neurons and sTNFR1 is thought to reflect the true biological activity of TNF-alpha. To evaluate the levels of the heavy subunit of neurofilament (NF-H) and soluble TNF receptor 1 (sTNFR1) in cerebrospinal fluid (CSF) as biomarkers of clinical severity of subacute sclerosing panencephalitis (SSPE), concentrations of NF-H and sTNFR1 in CSF of 34 patients with SSPE and in control subjects were measured by ELISA. The CSF NF-H levels were significantly higher in patients with SSPE than in controls (p<0.0001), and those in patients in Jabbour stage III were significantly higher than in patients in stage II (p=0.015). The CSF sTNFR1 levels in SSPE patients were significantly higher than those in controls (p=0.004), but there were no significant differences in CSF sTNFR1 levels between patients in Jabbour stages II and III. There was a significant correlation between CSF NF-H and sTNFR1 levels in patients with SSPE (p=0.011). We suggest that CSF NF-H levels can be used as a marker of development of neuronal degeneration in SSPE, and that TNF-alpha modifies the neurodestructive pathogenesis in SSPE.

Lesson Title: Introduction to Neurofilament and Soluble TNF Receptor 1 in Subacute Sclerosing Panencephalitis

Level: Primary through High School

Overview: In this lesson, we will learn about neurofilament and soluble TNF receptor 1, two proteins that are important in understanding subacute sclerosing panencephalitis (SSPE). We will explore their roles in the body, how they are measured in cerebrospinal fluid (CSF), and their significance as biomarkers for clinical severity of SSPE.

Section 1: Introduction to Neurofilament and Soluble TNF Receptor 1

Neurofilament is a type of protein that is found in the nervous system. It is one of the major components of the cytoskeleton, which is a network of fibers that help maintain the shape and structure of neurons. Soluble TNF receptor 1, or sTNFR1, is a protein that is thought to reflect the true biological activity of TNF-alpha, an inflammatory cytokine that is involved in various immune responses.

Section 2: Roles of Neurofilament and Soluble TNF Receptor 1 in the Body

Neurofilament plays a crucial role in the structural integrity of neurons. It helps maintain the shape and structure of these cells, which is essential for proper communication within the nervous system. On the other hand, sTNFR1 is involved in regulating the effects of TNF-alpha in the body. It can bind to TNF-alpha and prevent it from binding to its receptor, thus reducing inflammation and other immune responses.

Section 3: Measurement of Neurofilament and Soluble TNF Receptor 1 in Cerebrospinal Fluid

Researchers have found that levels of neurofilament and soluble TNF receptor 1 can be measured in cerebrospinal fluid (CSF). CSF is a fluid that surrounds the brain and spinal cord, and it contains cells and other substances that are important for maintaining the health of the nervous system. By measuring the levels of neurofilament and sTNFR1 in CSF, researchers can gain insights into the severity of SSPE and other neurological disorders.

Section 4: Significance of Neurofilament and Soluble TNF Receptor 1 as Biomarkers for Clinical Severity of SSPE

Studies have shown that levels of neurofilament and soluble TNF receptor 1 in CSF are significantly higher in patients with SSPE than in healthy controls. This suggests that these proteins may be useful as biomarkers for diagnosing and monitoring the severity of SSPE. In particular, high levels of NF-H in CSF have been associated with more severe cases of SSPE, while high levels of sTNFR1 have been linked to increased inflammation and immune response in the brain.

Section 5: Conclusion

In this lesson, we have learned about neurofilament and soluble TNF receptor 1, two proteins that are important in understanding subacute sclerosing panencephalitis (SSPE). We explored their roles in the body, how they are measured in cerebrospinal fluid (CSF), and their significance as biomarkers for clinical severity of SSPE. By understanding these proteins and their functions, we can gain valuable insights into the diagnosis and treatment of SSPE and other neurological disorders.

Lesson: Introduction to Medicinal Chemistry

### Section 1: Theoretical Concepts

Medicinal chemistry is the branch of chemistry that deals with the design, synthesis, and development of new drugs and their mechanisms of action. In this lesson, we will learn about the synthesis and biological evaluation of a new library of 4-(1,2-diarylbut-1-en-1-yl)isobutyranilides as potential inhibitors of topoisomerase II.

Topoisomerase II is an enzyme that plays a crucial role in DNA replication and transcription. It helps to unwind the double helix of DNA so that other enzymes can access the genetic material and carry out their functions. Inhibition of topoisomerase II can lead to the formation of DNA breaks, which can cause cell death. Therefore, inhibitors of topoisomerase II are potential candidates for cancer therapy.

### Section 2: Practical Examples

To synthesize the new library of 4-(1,2-diarylbut-1-en-1-yl)isobutyranilides, the researchers started with the corresponding 4-(1,2-diarylbut-1-en-1-yl)acids and then converted them to the desired isobutyramides by a one-pot, three-component coupling reaction. The new compounds were then tested for cytotoxicity in four different human tumor cell lines. The most active compound, 6g, was found to induce apoptosis and was suggested to interact with topoisomerase II.

Docking studies were performed to demonstrate the relevance of the interaction between the most active compound and topoisomerase II. These studies showed that the compound binds to the active site of the enzyme, preventing it from unwinding the DNA and causing cell death.

### Section 3: Real-World Scenarios

In this lesson, we have learned about the synthesis and biological evaluation of a new library of 4-(1,2-diarylbut-1-en-1-yl)isobutyranilides as potential inhibitors of topoisomerase II. We have also discussed the importance of this enzyme in DNA replication and transcription and how its inhibition can lead to cell death. By understanding the mechanisms of action of these compounds, researchers can design more effective drugs to treat cancer and other diseases.

### Glossary:
- Topoisomerase II: an enzyme that helps to unwind the double helix of DNA
- Cytotoxic: capable of causing cell death
- Apoptosis: a form of cell death that occurs naturally and is characterized by the shrinking of the cell and its contents
- Library: a collection of related things, in this case, a collection of chemical compounds
- Coupling reaction: a chemical reaction in which two or more molecules combine to form a larger molecule
- Active site: the part of an enzyme where the substrate binds and the chemical reaction takes place
- Docking studies: computer simulations that predict the interaction between a molecule and its target

### Conclusion:
In this lesson, we have learned about the synthesis and biological evaluation of a new library of 4-(1,2-diarylbut-1-en-1-yl)isobutyranilides as potential inhibitors of topoisomerase II. We have also discussed the importance of this enzyme in DNA replication and transcription and how its inhibition can lead to cell death. By understanding the mechanisms of action of these compounds, researchers can design more effective drugs to treat cancer and other diseases.

[T-cell responsiveness to specific group A streptococcus antigens in patients with primary erysipelas].
Peripheral blood leukocytic migratory activity (LMA) was studied in 63 patients with primary erysipelas. To reveal LMA, a screening cell migration test (SCMT) was used as an indicator of the cooperation of T- and B-lymphocytes and macrophages in the stimulation with polysaccharide A, surface proteins, L-antigen, hyaluronidase, streptolysin O, a complete S. pyogenes antigen complex after Grasse. The prognostic value of MAL parameters was established at week 1 after the onset of erysipelas. A rapid transition of LMA from the phase of acceleration to that of inhibition was shown to characterize the formation of an adequate response, to correspond to the good course of the disease, and to be followed by the low likelihood of recurrences. The probability of a subsequent recurrence is much higher than that when LMA tends to transit from suppression to acceleration and when LMA parameters are constant in the phase of suppression or acceleration. No transition of LMA to the phase of suppression in early convalescence suggests that the formation of an immune response to streptococcus is delayed.
