text: Manchester United winger Angel Di Maria is reportedly in ‘advanced talks’ with Paris St Germain.. The Argentine international has endured a below-par season at Old Trafford since his £59.7million move from Real Madrid, and is believed to have handed in a transfer request last week.. Paris has emerged as his most likely destination should he leave Old Trafford, and according to Le Parisien journalist Arnaud Hermant, the 27-year-old is in advanced negotiations with PSG.. The claim was made in a question-and-answer session on the French website, and fuels the speculation that the former Madrid man wants out of Manchester.. United are under no obligation to sell and would likely be reluctant to take a loss on Di Maria, but could find their hand forced should he really push for a transfer away..

Lesson: Transfer Negotiations in Football

Introduction:
In the world of football, transfer negotiations are a crucial part of the sport. Players move from one club to another in search of better opportunities, while clubs aim to strengthen their squads by signing new players. In this lesson, we will explore the process of transfer negotiations, including the roles of agents, clubs, and players.

Section 1: Understanding Transfer Negotiations

Topic 1: Roles of Agents
Agents play a significant role in transfer negotiations. They represent players and clubs in negotiating contracts, transfer fees, and other terms. Agents earn a commission based on the transfer fee, and they work to ensure that their clients get the best possible deal.

Topic 2: Roles of Clubs
Clubs are the primary parties involved in transfer negotiations. They have scouting teams that identify potential transfer targets, and they assess players' abilities, ages, and market values. Clubs also have financial constraints, which affect their ability to sign players.

Topic 3: Roles of Players
Players have a significant role in transfer negotiations. They can initiate discussions with clubs they want to join or request moves away from their current clubs. Players also have personal preferences, which can influence their decision-making during negotiations.

Section 2: Transfer Negotiations Process

Topic 1: Initial Discussions
Transfer negotiations often start with initial discussions between clubs and agents. These discussions may involve exploratory conversations about a player's availability, transfer fee demands, and contract terms.

Topic 2: Due Diligence
Clubs conduct due diligence on potential transfer targets to assess their abilities, fitness, and character. This process involves consulting with coaches, scouts, and medical staff.

Topic 3: Offer and Counteroffer
Once both clubs and agents have conducted their due diligence, they engage in offer and counteroffer negotiations. These negotiations can be lengthy and complex, involving multiple rounds of offers and counteroffers.

Topic 4: Agreement
If both parties reach an agreement on transfer fee and contract terms, they sign a contract that outlines the transfer details. The player then undergoes a medical examination and finalizes personal terms before completing the transfer.

Section 3: Real-World Examples

Topic 1: Angel Di Maria
Angel Di Maria is a prime example of a player whose transfer negotiations made headlines. Manchester United bought him for £59.7 million, but he struggled to adapt to the Premier League and wanted to leave the club. Paris St Germain emerged as his most likely destination, and he handed in a transfer request last week.

Topic 2: Gareth Bale
Gareth Bale's transfer negotiations have been ongoing for several years. Real Madrid signed him for £86 million in 2013, but his form has declined in recent seasons. Manchester United and other clubs have expressed interest in signing him, but Real Madrid wants to keep him.

Conclusion:
Transfer negotiations are a critical aspect of the football industry. Agents, clubs, and players all play essential roles in these negotiations, which involve initial discussions, due diligence, offer and counteroffer negotiations, and agreement signing. Real-world examples like Angel Di Maria and Gareth Bale illustrate the complexity of transfer negotiations. By understanding the process and its various components, we can better appreciate the intricacies of the football industry.

Lesson: Understanding International Political Economy

**Introduction**

International Political Economy (IPE) is a field of study that examines the interactions between politics and economics at the global level. It seeks to understand how countries interact with each other in the economic sphere and how political factors influence economic decisions. This lesson will provide an introduction to IPE, including its history, key concepts, and applications.

**History**

The study of IPE began in the late 19th century as economists and political scientists sought to understand the impact of globalization on their respective fields. In the 20th century, IPE became more prominent as countries increasingly engaged in international trade and investment. Today, IPE is an essential field of study for anyone interested in understanding how the global economy works.

**Key Concepts**

There are several key concepts in IPE that are essential for understanding the field. These include:

1. Globalization: The process by which countries become more interconnected economically, politically, and culturally.

Prevalence of food allergy in asthmatic patients.
This study was conducted to assess the role of clinical sensitivity to food on the pattern of bronchial asthma. A total of 1341 patients with asthma were included in the present study. The clinical sensitivity to food and its relation to respiratory symptoms were assessed cross-sectionally (using detailed questionnaires), and longitudinally during their regular visits to the asthma clinic using diet diary. Total IgE was determined for a subsample of the patients (No = 392). The prevalence of clinical sensitivity to food was 29%; about 2 thirds of the patients had high total IgE level. Asthmatic patients with clinical sensitivity to food present with some particular features which are considered risk factors that determine the occurrence and clinical pattern of asthma. In addition, some personal characteristics in the asthmatic patients make them at increased risk to have clinical sensitivity to food. From the clinical experience of asthma management in our clinic, the authors believe and emphasize that elimination of food items from the diet of an asthmatic patient should be considered after careful investigation and observation of the patient. In addition, some personal characteristics in the asthmatic patients make them at increased risk to have clinical sensitivity to food. Early detection of food allergy is an important preventive factor for food related respiratory symptoms. The natural course of food allergy is of resolution over time although this may differ between foodstuffs and may be variably affected by avoidance of the offending allergen.

Lesson: Introduction to Food Allergies

**Objective:** To introduce students to the concept of food allergies and their prevalence among asthmatic patients.

**Background:** Food allergies are an immune system reaction that occurs when the body comes into contact with certain foods. These reactions can range from mild to severe and can even be life-threatening. In this lesson, we will learn about the prevalence of food allergies in asthmatic patients and how they are related to respiratory symptoms.

**Section 1: What are food allergies?**

Food allergies are an abnormal immune response to certain foods. When a person with a food allergy eats something they are allergic to, their body produces antibodies called Immunoglobulin E (IgE). This causes certain cells in the body to release chemicals such as histamine, which can cause symptoms such as itching, redness, and swelling.

**Section 2: Prevalence of food allergies in asthmatic patients**

A study was conducted to assess the role of clinical sensitivity to food on the pattern of bronchial asthma. Out of 1341 patients with asthma, 29% had clinical sensitivity to food. This means that almost one-third of asthmatic patients have an allergic reaction to certain foods.

**Section 3: How are food allergies related to respiratory symptoms?**

Asthmatic patients with clinical sensitivity to food present with some particular features which are considered risk factors that determine the occurrence and clinical pattern of asthma. These features include eosinophilia (a high level of eosinophils in the blood), high total IgE level, and a positive skin test result for specific allergens. These factors can contribute to the development or worsening of asthma symptoms.

**Section 4: Personal characteristics that increase the risk of food allergies**

Some personal characteristics in asthmatic patients make them at increased risk to have clinical sensitivity to food. These include a family history of allergies, a personal history of allergies, and a young age at the onset of asthma.

**Section 5: Conclusion**

In conclusion, food allergies are a common problem among asthmatic patients, with almost one-third of them having an allergic reaction to certain foods. Understanding the relationship between food allergies and respiratory symptoms can help asthmatics manage their condition better and avoid triggers that can worsen their symptoms. By being aware of personal characteristics that increase the risk of food allergies, individuals can take preventative measures to reduce their chances of developing an allergy.

**Glossary:**

- IgE: Immunoglobulin E, an antibody produced by the immune system in response to allergens.
- Eosinophils: A type of white blood cell involved in the body's immune response.
- Total IgE: A measure of the total amount of IgE antibodies in the blood.
- Allergens: Substances that can cause an allergic reaction in sensitive individuals.
- Asthma: A chronic respiratory condition characterized by inflammation of the airways, leading to difficulty breathing.

**Self-Debate Discussion:**

- Do you know anyone who has a food allergy? What are some common symptoms of a food allergy reaction?
- Why do you think some people develop food allergies while others do not?
- How can asthmatics manage their condition better if they have a food allergy?

DirectFB

DirectFB (Direct Frame Buffer) is a software library with a small memory footprint that provides graphics acceleration, input device handling and abstraction layer, and integrated windowing system with support for translucent windows and multiple display layers on top of the Linux framebuffer without requiring any kernel modifications. DirectFB is free and open-source software subject to the terms of the GNU Lesser General Public License (LGPL).

The library allows developers an alternative to a full X Window System (X11) server used in Unix-like operating systems. DirectFB allows applications to talk directly to video hardware through a direct API, speeding up and simplifying graphic operations.

It is often used by games and embedded systems developers to circumvent the overhead of a full X Window System server implementation.  In 2006, a version of DirectFB was included in the software stack for the CE Linux Forum's Audio/Video Graphics Specification V2.

DirectFB can host XDirectFB, a rootless X server implementation that uses DirectFB windows for X11 top-level windows. XDirectFB is an interface that mimics the X11 interface through the DirectFB API to simplify running applications written for X11 on DirectFB.

DirectFBGL is an OpenGL extension for DirectFB/XDirectFB that uses Direct Rendering Infrastructure (DRI) in the Mesa 3D library to support OpenGL hardware acceleration.

Among the products that use DirectFB are LinuxTV, Ben Nanonote, the unreleased Palm Foleo mobile companion, the webOS operating system, Panasonic Viera Connect TVs and the Philips TVs based on jointSPACE.

Lesson: Introduction to DirectFB

## Section 1: Theoretical Concepts

DirectFB is a software library that provides graphics acceleration, input device handling, and an abstraction layer for a windowing system. It runs on top of the Linux framebuffer without requiring any kernel modifications. This means that it can be used on any Linux distribution without the need for special patches or modifications.

DirectFB allows developers to create applications that can talk directly to video hardware through a direct API. This speeds up and simplifies graphic operations, making it ideal for games and embedded systems development.

The library also includes an integrated windowing system with support for translucent windows and multiple display layers. This allows for more advanced graphical user interfaces (GUIs) that can be used in a variety of applications.

## Section 2: Practical Examples

To demonstrate the practical use of DirectFB, let's consider a simple example. Suppose we want to create a game that runs on Linux. We can use DirectFB to create a window for the game and handle input events such as keyboard presses and mouse clicks. We can also use the library's graphics acceleration to create smooth animations and special effects.

Here's some sample code to create a window using DirectFB:

```c
#include <dfb/dfb.h>

int main(int argc, char **argv) {
    DFB *dfb;
    DFBWindow *window;

    dfb = DFBInit();
    if (!dfb) {
        printf("DFBInit failed.\n");
        return 1;
    }

    window = DFBCreateWindow(dfb, &dfb_screen_config, 0, 0, 640, 480);
    if (!window) {
        printf("DFBCreateWindow failed.\n");
        return 1;
    }

    DFBSetWindowPosition(window, 100, 100);
    DFBSetWindowSize(window, 640, 480);

    DFBClose(window);
    DFBRelease(dfb);

    return 0;
}
```

This code creates a window with a size of 640x480 pixels at position (100, 100) on the screen. The window is then closed, and the DFB library is released.

## Section 3: Self-Debating Discussions

One advantage of using DirectFB over a full X Window System server implementation is that it has a smaller memory footprint. This means that it can be used on systems with limited resources, such as embedded systems or mobile devices.

However, one disadvantage of DirectFB is that it may not be as feature-rich as a full X11 implementation. For example, it does not support some advanced features such as Xinerama or RandR. Additionally, some applications may rely on specific X11 libraries or extensions that are not available in DirectFB.

In conclusion, DirectFB is a powerful tool for developers who need to create graphical applications that run on Linux. Its small memory footprint and direct API make it ideal for embedded systems and games development. However, its lack of some advanced X11 features may limit its usefulness for certain applications.

## Glossary
- DirectFB: A software library that provides graphics acceleration, input device handling, and an abstraction layer for a windowing system.
- Linux framebuffer: A device that provides access to the video memory of a computer system running the Linux operating system.

Lesson: Introduction to Single Port Surgeries

## Section 1: Theoretical Concepts
In this lesson, we will learn about single port surgeries, also known as SILS or scarless surgeries. These surgeries involve making a small incision in the umbilicus (navel) to perform the surgery. This technique is becoming increasingly popular due to its many benefits over traditional surgeries, which often require larger incisions and result in visible scars.

## Section 2: Practical Examples
Let's consider an example of a patient who needs to undergo a hernia repair. In the past, this surgery would require a large incision in the abdomen, resulting in a visible scar. However, with single port surgeries, the surgeon can make a small incision in the umbilicus and use a specialized camera and instruments to perform the surgery. The patient will have a small scar that is barely visible, if at all.

## Section 3: Real-World Scenarios
Single port surgeries are not only beneficial for medical reasons but also for cosmetic purposes. Many patients prefer to have minimal scarring after a surgery, as it can be embarrassing or uncomfortable to show off their body. In addition, single port surgeries can be performed using a SILS port, which is placed into the umbilicus and used to perform the surgery. This means that there is only one incision point, making the final scar in the umbilicus virtually invisible.

## Glossary
- Single port surgeries: A type of surgery where a single incision is made in a specific location on the body, usually the umbilicus, to perform the surgery.
- SILS port: A specialized camera and instruments used to perform single port surgeries.
- Umbilicus: The navel, or the area where the belly button is located.
- Hernia repair: A surgical procedure to fix a hernia, which is a bulge or tear in the muscle wall of the abdomen.

## Conclusion
In conclusion, single port surgeries offer many benefits over traditional surgeries, including minimal scarring and improved cosmetic appearance. By understanding the theoretical concepts, practical examples, and real-world scenarios of single port surgeries, we can better appreciate the importance of this innovative surgical technique.

Lesson Title: The Role of Boats in World War II

## Section 1: Introduction
In this lesson, we will learn about the role of boats in World War II, specifically the landing craft produced by Chris-Craft. We will explore how these boats were used in the war and how they contributed to the Allied forces' victory.

## Section 2: Theoretical Concepts
A landing craft is a small, shallow draft vessel used to transport soldiers and equipment from ships to shore. During World War II, these boats were essential for amphibious invasions, which involved attacking an enemy on both land and sea.

## Section 3: Practical Examples
Chris-Craft, a boat manufacturer based in Algonac, Michigan, played a significant role in producing landing craft for the war effort. Their factories were transformed into assembly lines, producing thousands of these boats each month. The landing craft produced by Chris-Craft were used in several major battles, including D-Day, the Battle of Iwo Jima, and the Battle of Okinawa.

## Section 4: Real-World Scenarios
The landing craft produced by Chris-Craft were instrumental in helping the Allied forces invade enemy-occupied territories. Soldiers would load onto the boats from larger ships and then disembark onto the shore. These boats were also used to transport equipment and supplies to the front lines.

## Section 5: Self-Debating Discussion
Why were landing craft so important during World War II?

Answer: Landing craft were crucial because they allowed the Allied forces to attack enemies on both land and sea. They provided a way for soldiers and equipment to be transported from ships to shore, which was necessary for amphibious invasions. Without these boats, it would have been much more difficult for the Allies to successfully invade enemy-occupied territories.

## Glossary
Landing Craft: A small, shallow draft vessel used to transport soldiers and equipment from ships to shore.

Concentration-dependent inhibitory effects of apolipoprotein E on Alzheimer's beta-amyloid fibril formation in vitro.
Recently, many research groups have examined the effect of apolipoprotein E (apoE) on beta-amyloid fibril (betaAf) formation in vitro. However, their data were somewhat controversial and no exact kinetic assessment of the role of apoE has thus far been available. We examined the effect of human apoE on betaAf formation in vitro, starting with various concentrations of freshly prepared beta-amyloid(1-40) (beta1-40) and using fluorescence spectroscopy with thioflavine T. When 50 microM of beta1-40 was incubated with a 1:1000 to 1:100 molar ratio of apoE, a dose-dependent inhibitory effect of apoE was observed. Both the nucleation and extension phases of betaAf formation in vitro were inhibited by apoE. On the other hand, when 300 microM of beta1-40 was incubated with a 1:100 molar ratio of apoE, the inhibitory effect of apoE was completely abolished. We then focused our study on the kinetics of the inhibitory effect of apoE on the extension phase of betaAf formation in vitro, utilizing the recently established first-order kinetic model of betaAf extension in vitro [Naiki, H., & Nakakuki, K. (1996) Lab. Invest. 74, 374-383]. The mathematical treatment of the data suggests that apoE inhibits the extension of betaAf in vitro, by making a complex with beta1-40, thus eliminating free beta1-40 from the reaction mixture. The equilibrium association constant with beta1-40 was practically the same among the three major recombinant apoE isoforms. These results indicate that the effects of apoE on betaAf formation in vitro is differential and could settle some of the controversy about beta-amyloid-apoE interaction in vitro.

Lesson: Introduction to Inhibition in Chemistry

**Objective:** To introduce the concept of inhibition in chemistry and its applications in understanding biological systems.

**Glossary:**
- Inhibition: A process in which the activity of an enzyme or a chemical reaction is reduced or stopped by a substance called an inhibitor.
- Enzyme: A protein that acts as a catalyst to speed up a chemical reaction in a biological system.
- Reaction rate: The speed at which a chemical reaction occurs.

**Section 1: Introduction to Inhibition**
In chemistry, inhibition refers to the process by which the activity of an enzyme or a chemical reaction is reduced or stopped by a substance called an inhibitor. In biological systems, inhibitors are often used to regulate the activity of enzymes and maintain a balance within the system. Understanding inhibition is essential for studying the functioning of biological systems and developing drugs to treat diseases.

**Section 2: Types of Inhibition**
There are two main types of inhibition: competitive and non-competitive. In competitive inhibition, the inhibitor competes with the substrate for the active site of the enzyme. This means that the inhibitor must bind to the enzyme before the substrate can bind, reducing the reaction rate. In non-competitive inhibition, the inhibitor binds to an allosteric site on the enzyme, changing its shape and reducing its ability to bind to the substrate.

**Section 3: Examples of Inhibition in Biological Systems**
One example of inhibition in biological systems is the regulation of blood clotting. In this process, an enzyme called thrombin is activated to convert a blood clotting factor called fibrinogen into fibrin. An inhibitor called antithrombin can bind to thrombin, slowing down the conversion of fibrinogen to fibrin and preventing excessive blood clotting.

**Section 4: Applications of Inhibition in Drug Development**
Understanding inhibition is crucial in drug development because it allows scientists to design drugs that target specific enzymes or reactions in the body. For example, drugs that inhibit the activity of an enzyme involved in the growth of cancer cells can be used to treat cancer.

**Conclusion:**
In this lesson, we introduced the concept of inhibition in chemistry and its applications in understanding biological systems. We discussed the two main types of inhibition and provided an example of inhibition in biological systems. Finally, we explored the importance of inhibition in drug development. By understanding inhibition, scientists can develop more effective drugs to treat diseases and improve human health.

Half-Life remake Black Mesa is ending its five-year stint in Early Access next week. The bulk of the game has been finished and playable for a long time, but with the arrival of the brand new Xen levels, some map tweaks and AI improvements, it's finally approaching that last development milestone.

Developer Crowbar Collective announced the launch update in January, and now we've got a release date: March 5. Studio boss Adam Engles revealed the date in a post looking back at the game's long development, a process he joined in 2006 when it was still an unofficial Half-Life mod. From there, he became the art lead, project lead and now owns the company.

"Through luck, hard work, and maybe a bit of ignorance we didn’t shy away from our goal of bringing this game to completion," he writes. "We are proud of what we built. We think this upcoming 1.0 release is the best, most polished, and most fun version of the game yet. The anticipation and excitement around our project is beyond flattering."

Engles emphasises, however, that development is not over. With 1.0 ready, there will still be bugs to fix, and he wants to manage expectations.

"This is not to downplay, or make excuses, but as the person who drafts most of these media posts, I think it is important to break away from the marketing and the 'hype.' Before Astroneer launched, they made a blog post about managing expectations for their game, and it really resonated with me, and inspired me to someday write a post like this one. We are super excited to have Black Mesa be 'complete,' but acknowledge it is not perfect and won’t ever be perfect."

If the itch is too great and you can't wait for March 5, the whole game is already playable from start to finish, and is much larger than the team had planned. The meatiest addition is probably Xen, the alien world we hardly spend any time exploring in the original game. Crowbar Collective has fleshed this section out with what's effectively an expansion, and one full of wholly original levels and mechanics.

There's still quite a lot coming with the 1.0 patch, however, and you can check out the changes in last month's developer preview.

Confronting the rapidly growing Iranian nuclear threat

Audrey Jacobs

The United States and our close allies, including Israel, Britain, Canada and other Western countries, are confronting today the greatest threat we’ve faced in decades. As confirmed by the recent report by the International Atomic Energy Agency, the Islamic Republic of Iran is continuing its headlong march toward acquiring a weaponized nuclear capability. The United States and our allies must continue to explore the full range of options available and to coordinate a strong, multilateral approach to make sure that Iran does not succeed in developing nuclear weapons.

Last month’s report by the International Atomic Energy Agency expressed “serious concerns regarding possible military dimensions to Iran’s nuclear program.” Specifically, the IAEA found, “Iran has developed the capability to enrich uranium to a level of up to 20 percent U-235,” more consistent with acquiring a weapon than, as Tehran speciously contends, with producing nuclear energy peacefully. The agency further found that “the product of this program would be converted into metal for use in the new warhead which was the subject of the missile re-entry vehicle studies.”

While much of the technology employed in developing a nuclear capability qualifies as “dual-use” – i.e., possessing both civilian and military applications – even the generally conservative and conciliatory IAEA has now determined that the overwhelming majority of Iran’s work is “highly relevant to a nuclear weapon program” – the measured, diplo-speak equivalent of a red alert.

In short, the report confirms that a nuclear-armed Iran is the most severe national security threat currently facing the United States, Israel and many Western countries. Reuters recently reported that a senior U.S. military official acknowledged “the biggest threat to the United States and to our interests and to our friends ... has come into focus, and it’s Iran.” The IAEA report dovetails with recent allegations that Iranian intelligence planned a high-profile assassination campaign on American soil.

Iran’s leaders openly validate these fears in affirming their genocidal aims. Ali Khamenei, Iran’s Supreme Leader, has repeatedly called for “death to America,” while Mahmoud Ahmadinejad, the country’s president, has vowed to “wipe Israel off the map.” In addition, Iran takes continual action in support of these goals, arming and supporting terrorist organizations like Hezbollah in Lebanon, Hamas and Islamic Jihad in Gaza, and others to commit ongoing attacks against citizens of Israel, the United States and other Western countries.

So how should the West respond to the latest news?

We must impose ever-intensifying economic sanctions on the Iranian regime. The recent measures announced by President Barack Obama and the leaders of Britain and Canada send a strong and clear message to Iran that their nuclear weapons program will not be permitted. Steps like these “represent a significant ratcheting up of pressure on Iran, its sources of income and its illegal activities,” Secretary of State Hillary Clinton stated.

Important as these steps are, it is likely that they will not be sufficient. They should be followed as needed by more powerful sanctions. Specifically, the president has already identified “the entire Iranian banking sector – including the Central Bank of Iran – as a threat to governments or financial institutions that do business with Iranian banks.” Britain has already included the Central Bank of Iran amongst its sanctions targets. At the right time, the United States should follow suit, and begin the process of formally sanctioning the Central Bank of Iran in order to cripple Iran’s ability to finance its nuclear activities.

Some Iran experts have also proposed directly targeting Tehran’s oil exports, which account for anywhere from 50 to 75 percent of the country’s budget, specifically by sanctioning the National Iranian Oil Company.

Iran’s determination to obtain and exploit nuclear weapons capabilities poses a major strategic threat to the United States, Israel and our other allies in 2012 and beyond. It is crucial that our government and the governments of our allies hear from as many of their citizens as possible that we support their immediate intensification of all possible measures to counter this potentially devastating threat and to ensure continued security and freedom for all.

Lesson: Confronting the rapidly growing Iranian nuclear threat

Introduction

The United States and our close allies, including Israel, Britain, Canada, and other Western countries, are confronting today the greatest threat we’ve faced in decades. As confirmed by the recent report by the International Atomic Energy Agency (IAEA), the Islamic Republic of Iran is continuing its headlong march toward acquiring a weaponized nuclear capability. In this lesson, we will explore the reasons behind this threat, the actions taken by the international community to address it, and the potential consequences of a nuclear-armed Iran.

Section 1: Understanding the Threat

**Why is Iran's nuclear program a threat?**

Iran's nuclear program poses a significant threat to international security because it could potentially lead to the development of nuclear weapons. A nuclear-armed Iran would destabilize the region, increase the risk of nuclear proliferation, and undermine global non-proliferation efforts. Additionally, Iran's leadership has made threats against Israel, raising concerns that they may use nuclear weapons to carry out those threats.

**What has the international community done to address the threat?**

The international community, led by the United States and our close allies, has taken several steps to address the growing Iranian nuclear threat. These include:

1. Imposing economic sanctions on Iran to limit its ability to finance its nuclear program.
2. Working with the IAEA to monitor and verify Iran's compliance with its nuclear obligations.
3. Engaging in diplomatic negotiations with Iran to persuade them to abandon their nuclear ambitions.
4. Coordinating with regional partners to enhance security and deter potential aggression from Iran.

Section 2: Analyzing the Options

**What options does the international community have to address the Iranian nuclear threat?**

The international community has several options to address the growing Iranian nuclear threat, including:

1. Diplomacy: Continuing diplomatic engagement with Iran to persuade them to abandon their nuclear program and agree to a verifiable and enforceable deal.
2. Economic sanctions: Strengthening and expanding economic sanctions to further isolate Iran and limit its ability to fund its nuclear program.
3. Military action: Considering the use of military force to destroy Iran's nuclear facilities, should diplomacy and economic sanctions fail.
4. Accepting a nuclear-armed Iran: Some argue that the international community should accept a nuclear-armed Iran as a reality and focus on managing the consequences.

Section 3: Evaluating the Consequences

**What are the potential consequences of a nuclear-armed Iran?**

The potential consequences of a nuclear-armed Iran are significant and far-reaching, including:

1. Regional instability: A nuclear-armed Iran would likely lead to an arms race in the Middle East, as other countries seek to match Iran's capabilities.
2. Nuclear proliferation: Iran's acquisition of nuclear weapons could encourage other states, such as Saudi Arabia or Egypt, to pursue their own nuclear programs.
3. Undermining non-proliferation efforts: Iran's possession of nuclear weapons would undermine global non-proliferation efforts and make it harder to prevent other countries from acquiring nuclear capabilities.
4. Threats to Israel: A nuclear-armed Iran could embolden its leaders to make good on their threats to attack Israel, potentially leading to a devastating conflict.

Conclusion

In conclusion, the growing Iranian nuclear threat is a serious concern for the international community. While there are several options available to address this threat, each comes with its own set of risks and consequences. Ultimately, it is up to the international community to work together to find a solution that ensures the safety and security of all nations. By understanding the threat, analyzing the options, and evaluating the consequences, we can make informed decisions about how to confront this challenge and protect our interests.

Stargazing: Getting Started

Making the Brightest, Rarest Galaxies

Some of the universe’s most luminous galaxies are also the most mysterious. New simulations shed light on how these galaxies formed.

This simulation snapshot shows gas and light around a bright central galaxy (white). Ambient gas (blue-green) was long ago expelled by the central galaxy, as well as the large spiral to its left and numerous smaller galaxies. Now the gas gravitates toward the central galaxy and fuels its prodigious star formation. Robert Thompson (NCSA)

When the universe was less than 3 billion years old, it was a markedly different place. It was much smaller and more crowded, teeming with young galaxies. So it’s no surprise that astronomers long thought that galaxy mergers were responsible for submillimeter galaxies, rare and brilliant stellar metropolises that radiate powerfully at wavelengths slightly shorter than microwaves.

Seen only in the distant universe, these bright, churning masses of star formation are unlike anything around today. But they evaded detection until only recently, their stellar construction sites hidden behind clouds of dust. Their discovery comes thanks to submillimeter surveys — dust absorbs visible light but it glows at longer infrared wavelengths, which in turn stretch out as they pass through the expanding universe. Telescopes such as ALMA are now finding these rare gems in greater numbers.

Even as observational astronomers are unveiling a new view of galaxy evolution, theorists are having a heck of a time recreating it. Under the merger scenario, two big galaxies merge into a single giant, stirring up gas and setting off a flash of star formation that fades away after a few tens of millions of years. But theorists applying this scenario haven’t been able to match observations

Now a new simulation published in the September 24 Nature has done just that using an ingredient missing in previous calculations: stars.

More specifically, the key component Desika Narayanan (Haverford College) and colleagues incorporated in their recipe was stellar feedback. Aging and exploding stars drive gas outward, then the massive galaxy’s pull brings it raining back down, akin to a galactic-scale water cycle.

Stars Beget Stars

You might think accounting for stars would be obvious, considering these galaxies are bursting with them —submillimeter galaxies create 500 to 1,000 Suns’ worth of stellar mass every year, up to 1,000 times the Milky Way’s current output. But in cosmological simulations, where computers calculate the effects of gravity on scales on the order of 100 million light-years, making out details on the light-year scale proves all but impossible.

Narayanan and colleagues separate the big picture from the finer details into two stages. First, they simulate a cube of space 16 million light-years on a side at low resolution. As is typical in cosmological simulations, this first calculation only accounts for gravity’s effect on dark matter particles. It ignores the regular matter that makes up stars, assuming dark matter’s pull will draw it in to form galaxies and clusters of galaxies within each dark clump. Once the team identified clumps that would become a submillimeter galaxy, they re-simulated a close-up, high-resolution view, this time including the effects of stars and their winds.

Tracking galaxies’ growth over about 2 billion years, the team found that the starburst (and submillimeter-emitting) phase isn’t a short, merger-inspired flash. It’s a prolonged luminous chapter that lasts roughly 750 million years.

This rotating view drawn from the simulation shows 3D detail of a submillimeter galaxy and its neighbors:

Although the galaxy might well experience mergers during this time frame, those galactic encounters wouldn’t support such intense star formation over such a long period of time. Instead, it’s the stellar feedback that’s maintaining and stirring up a reservoir of gas for future stars.

Mergers vs. Feedback

This study is the latest to question the role of mergers in galaxy evolution — see the September issue of Sky & Telescope for an in-depth look at this sea change.

“It’s an interesting set of results,” agrees Andrew Blain (University of Leicester). But he cautions that the details of stellar feedback are “very substantially more complex” than the simulations included in this work.

The study also doesn’t include feedback from gorging supermassive black holes, which should affect the early evolution of large galaxies, but that’s only a matter of time. Coauthor Philip Hopkins (Caltech) says they’ve already started running similar simulations that include black holes.

“The biggest question is whether the regions described in the paper actually do match the properties [of observed submillimeter galaxies],” Blain adds. Ongoing ALMA observations (such as that of SDP.81 and others) will put this new idea to the test.

Lesson: Stargazing - Understanding the Formation of Bright and Mysterious Galaxies

Introduction:
In this lesson, we will learn about the formation of bright and mysterious galaxies, known as submillimeter galaxies. These galaxies are some of the most luminous in the universe and have fascinated astronomers for years. We will explore how they formed, what makes them so unique, and how simulations can help us understand their properties.

I. Theoretical Concepts:

A. What are submillimeter galaxies?
Submillimeter galaxies are a type of galaxy that emit most of their radiation at submillimeter wavelengths. They are typically found in the early universe, which is less than 3 billion years old.

B. How do these galaxies form?
Scientists believe that submillimeter galaxies form when two or more galaxies merge together. This process is called hierarchical clustering. The merging of galaxies can cause a lot of gas and dust to be expelled from the system, leaving behind only the brightest and most massive stars.

C. Why are they so mysterious?
Submillimeter galaxies are mysterious because they are very rare and bright. They also contain a lot of gas and dust, which is necessary for creating new stars. However, the gas and dust in these galaxies seems to be missing, leading scientists to wonder where it has gone and how the galaxies continue to shine so brightly.

II. Practical Examples:

A. Simulations and Observations
To better understand submillimeter galaxies, scientists use computer simulations to model their formation and behavior. They also observe these galaxies using powerful telescopes that can detect submillimeter radiation.

B. Gas and Light Around Galaxies
Simulation snapshots show gas and light around bright central galaxies. The gas is blue-green, indicating that it was expelled by the central galaxy long ago. The large spiral to its left and numerous smaller galaxies also expelled gas, which now gravitates towards the central galaxy and fuels its prodigious star formation.

III. Critical Thinking:

A. What role do simulations play in our understanding of submillimeter galaxies?
Simulations are crucial for understanding the properties of submillimeter galaxies because they allow scientists to test different theories and models about how these galaxies form and evolve over time.

B. How do we know if our theories about submillimeter galaxies are correct?
We can test our theories by comparing them to observational data collected by telescopes. If our theories match the data, we can be more confident in their accuracy. However, if the data does not match our theories, we must revise our ideas and come up with new explanations.

Glossary:
- Submillimeter: A unit of length equal to one thousandth of a millimeter, or one millionth of a meter.
- Galaxy: A massive object composed of stars, gas, and dust, held together by gravity.
- Hierarchical Clustering: A process by which smaller structures merge together to form larger structures over time.
- Radiation: Energy that travels through space in the form of waves or particles.
- Telescope: An instrument used to observe objects in space by collecting and focusing light from those objects.

Conclusion:
In this lesson, we learned about the formation of bright and mysterious galaxies known as submillimeter galaxies. We explored how simulations can help us understand their properties and how observations can confirm or refute our theories. By understanding the formation and evolution of these unique galaxies, we can gain valuable insights into the history and structure of the universe.

# Lesson 1: Introduction to Financing and Marketing Merchant Power
## Section 1: Overview
In this lesson, we will learn about financing and marketing merchant power. We will cover the following topics:
- What is merchant power?
- Why is it important?
- How does it work?
## Section 2: What is Merchant Power?
Merchant power refers to the ability of merchants to negotiate better deals with suppliers and manufacturers. It allows them to buy products at lower prices and sell them at higher prices, thereby increasing their profits. This is important because it helps small businesses compete with larger ones.
## Section 3: Why is Merchant Power Important?
Merchant power is important because it allows small businesses to compete with larger ones. It also helps them to negotiate better deals with suppliers and manufacturers, which can lead to lower costs and higher profits. Additionally, it enables merchants to offer unique products that are not available elsewhere, which can attract more customers and increase sales.
## Section 4: How Does Merchant Power Work?
Merchant power works by allowing merchants to buy products at lower prices and sell them at higher prices. This is achieved through negotiations with suppliers and manufacturers. Merchants can also use their buying power to influence the design and production of products, which can help them to differentiate themselves from competitors.
## Section 5: Practical Examples
One example of merchant power in action is the way that Walmart uses its buying power to negotiate better deals with suppliers. By purchasing large quantities of products, Walmart can demand lower prices from suppliers, which allows them to offer lower prices to customers. Another example is how Amazon uses its merchant power to negotiate better deals with publishers and authors, which allows them to offer a wider selection of books at lower prices.
## Section 6: Conclusion
In conclusion, merchant power is an important tool for small businesses to compete with larger ones. By negotiating better deals with suppliers and manufacturers, merchants can offer unique products at lower prices, which can attract more customers and increase sales. Understanding how merchant power works can help small business owners to make informed decisions about their purchasing and pricing strategies.

Lesson: Acquiring Companies and their Financial Terms

**Introduction:** In this lesson, we will learn about acquiring companies and their financial terms. We will start by understanding what it means for a company to acquire another company and then move on to understanding the financial terms involved in such transactions.

**Section 1: What does it mean for a company to acquire another company?**

When one company takes over another company, it is called an acquisition. The acquiring company buys the target company and takes control of its operations. This can happen for many reasons, such as expanding the business, gaining access to new markets, or improving the company's products or services.

**Section 2: Financial Terms**

There are several financial terms that are commonly used when discussing acquisitions. Let's take a look at some of them:

- **Purchase Price:** This is the amount of money that the acquiring company pays to the target company. It can be paid in cash, stocks, or a combination of both.
- **Earnout:** This is a payment that the seller of the company may receive after the acquisition has been completed. It is based on the future performance of the company.
- **Stock Purchase:** In this type of acquisition, the acquiring company buys the shares of the target company from its shareholders.
- **Asset Purchase:** In this case, the acquiring company buys only specific assets of the target company, rather than the entire company.
- **Debt Purchase:** This is when the acquiring company takes over the debt of the target company.

**Section 3: Example**

Let's say that Company A wants to acquire Company B. Company A offers $10 million in cash and $5 million in stocks to Company B's shareholders. Company B agrees to the offer, and the deal is closed. In this example, the purchase price was a combination of cash and stocks.

It is known to provide an EOAT to grip objects for robots. The common EOAT gripper has a linkage which is pivotally connected to a hydraulic or pneumatic actuator. Prior to the present invention, a change in the gripping force exerted by the gripper required a change in the force exerted by the actuator. The above mandates that the pneumatic or hydraulic system used for powering the actuator have a variable pressure system, therefore requiring a pressure regulator to give the desired actuator pressure. It is desirable to provide an EOAT gripper whose gripping force may be modified without changing the actuator force.
Another characteristic of EOAT grippers before the present invention is that most grippers are ideally suited to handle workpieces with regular polygonal cross sectional areas within a rather limited dimensional range. When changing dimensional sizes or changing workpiece shape, it is usually required to design another EOAT gripper. Therefore, the robot must be supplied with the separate EOAT gripper whenever the workpiece is dimensionally changed. It is desirable to provide an EOAT gripper which can easily be adjusted to handle workpieces in a wider dimensional range. It is also desirable to provide an EOAT gripper which can be used on workpieces having various cross sectional shapes, many of which do not have a regular polygonal cross sectional area.
