The present invention relates, in general, to amorphous refractories and more particularly to a novel and useful refractory which is settable at low temperatures and which is used chiefly for lining containers and troughs, such as melting furnaces, smelting furnaces, ladles, tundishes, cupola subfurnaces, and the like.
As is well known, conventional refractory linings are applied as kneaded with about 3 to about 10% by weight of water or other liquid. The resulting lining must be heated at a high temperature for drying before the lined structure is placed into actual operation. Thus, a large amount of heat energy is required and the procedure is time consuming. Additionally, the heat drying procedure involves a serious risk that the lining may be ruinously damaged by cracking and separation. It has, therefore, long been considered desirable in the concerned industry to basically overcome the above problems in order to decrease cost, reduce the shutdown period of the lined structure and prolong the life of the lining.

Lesson: Introduction to Refractories

### Section 1: Theoretical Concepts

Refractories are materials that can withstand high temperatures without undergoing significant changes in their physical properties. They are commonly used in industries where temperatures are extremely high, such as glassmaking, cement production, and steel manufacturing. In this lesson, we will learn about the properties of refractories, their applications, and the factors that influence their performance.

### Section 2: Practical Examples

Let's consider a real-world scenario where refractories are used. A glass manufacturing plant uses a furnace to melt raw materials at high temperatures. The furnace lining is exposed to extreme heat, and it needs to be durable and resistant to thermal shock. A refractory material is chosen for this application because it can withstand the high temperatures without breaking down.

### Section 3: Self-Debating Discussions

One of the challenges in selecting refractory materials is determining their thermal conductivity. Thermal conductivity is a measure of how well a material conducts heat. In general, materials with low thermal conductivity are better at insulating, while materials with high thermal conductivity are better at transferring heat. However, some refractory materials have both low thermal conductivity and high thermal conductivity, depending on their composition and structure.

### Glossary
- Refractory: A material that can withstand high temperatures without undergoing significant changes in its physical properties.
- Thermal conductivity: The ability of a material to conduct heat.
- Thermal shock: A sudden change in temperature that can cause a material to break down or fail.
- Furnace: A device used to heat materials to high temperatures for manufacturing processes.
- Lining: The inner surface of a furnace or other industrial equipment.
- Raw materials: The starting materials used in manufacturing processes.
- Thermal insulation: The process of preventing heat from flowing between two objects in thermal contact.

### Conclusion
In this lesson, we learned about the properties of refractories, their applications in various industries, and the factors that influence their performance. We also explored a real-world scenario where refractories are used and discussed the challenge of selecting materials with the right thermal conductivity. By understanding these concepts, we can apply our knowledge to new problems and make informed decisions when selecting refractory materials for specific applications.

In a sign the Australian Space Agency is already opening up new doors for Australian industry, NASA says it will be launching rockets from Arnhem Space Centre, in Nhulunbuy in the Northern Territory, in 2020.

Minister for Industry, Science and Technology Karen Andrews has also indicated she will encourage space tourism from Australia. She wants passengers to experience zero-gravity from the convenience of a domestic airport.

Read more: Five ethical questions for how we choose to use the Moon

But who gets to decide what can be launched into space? That depends on where the launch takes place, and in the case of Australia those rules are currently under review.

International treaty

The authority for who approves, supervises and grants permission for launch of space objects is based on UN treaties that provide a framework for international space law. The most important is the Outer Space Treaty (OST), which entered into force in 1967.

Article VI of the OST provides that nation states (that is, countries) bear “international responsibility” for “national activities” undertaken in outer space by government and commercial users alike.

States remain responsible for activities undertaken by commercial entities – for example, companies such as SpaceX – and are obliged to undertake ongoing supervision of such activities.

How individual countries choose to conduct such supervision is left entirely up to them, but in most cases it is done by way of domestic space law.

Another international treaty, the Liability Convention provides that the liability of the state extends to all launches that are made from that state’s territory. For example, the US is legally responsible for all launches that take place from that country as well as for launches elsewhere that it procures.

This imposes a significant burden on the state to ensure that international requirements are complied with.

Domestic space law regulates matters such as the granting of launch permits, and insurance and indemnity requirements. In Australia, this is achieved through the Space Activities (Launches and Returns) Act 2018. In New Zealand, the Outer Space and High-altitude Activities Act 2017, applies.

The Starlink network

In the US, it’s the Federal Communications Commission (FCC) that gave Elon Musk’s SpaceX permission to launch thousands of Starlink satellites as part of a plan to create a low-orbit internet network.

The licence is for one constellation of 4,409 satellites and a second constellation of 7,518 satellites. The FCC requires launch of half of the total number planned within six years.

The first 60 satellites were launched into orbit last month, and have already given rise to a number of concerns.

Read more: Lights in the sky from Elon Musk's new satellite network have stargazers worried

Scientists and astronomers are worried such a large constellation of satellites will be visible to the naked eye in the night sky. In response, Musk has already agreed to make the next batch less shiny.

Penalties apply

As well as granting launch licences, the FCC can also issue fines for any unlicensed launch by US operators.

Swarm Technologies launched four SpaceBee satellites from India in January 2018, after having been denied a licence from the FCC. The FCC was concerned the satellites were too small to be effectively tracked by the US Space Surveillance Network.

FCC subsequently fined Swarm US$900,000, partly as a way to spread the word that licensing of launching is a serious business but because the company had also performed other activities that required FCC authorisation.

In addition to presenting issues for tracking, new satellites also presented a hazard in terms of their potential to create large debris fields.

Notably, there are no binding international laws with respect to the creation of space debris. There are non-binding Space Debris Mitigation Guidelines issued by the UN Inter-Agency Space Debris Coordination Committee. But these are only guidelines and are frequently overlooked in the interests of commercial expediency.

The 2018 Australian Act does require the applicant for various Australian licences (such as a launch permit) to include “a strategy for debris mitigation”. This may include, for example, a plan to de-orbit the satellite after a certain number of years.

Launches from Australia

Australia’s first claim to fame as a space-faring nation was the launch of WRESAT (the Weapons Research Establishment Satellite) from Woomera, South Australia, in 1967.

But the launch platforms on nearby Lake Hart were dismantled following the departure to French Guiana in 1971 of the European Launcher Development Organisation (ELDO) – whose name ELDO still graces the sole hotel in Woomera, in outback South Australia.

From this time until the late 1990s there was little interest in space launches from Australia.

Read more: Lost in space: Australia dwindled from space leader to also-ran in 50 years

The Space Activities Act 1998 was enacted in response to a brief interest in US company Kistler Aerospace developing a spaceport at Woomera, SA.

But no spaceport was constructed nor any launches conducted. A review of the Space Activities Act and of the Australian space industry in 2016-2017 led to the new Space Activities (Launches and Returns) Act in 2018.

This Act envisions a broader role for domestic space industries, including but not limited to, launch.

The rules which flesh out the details of the application of that licensing regime are currently open for public review and comment. The deadline for making a submission closes at the end of this week.

### Section 1: Introduction to Space Law

Space law is a branch of international law that deals with the activities of nations and individuals in outer space. It covers topics such as space exploration, satellite communication, and space tourism. The first human-made object to be launched into space was Sputnik 1 in 1957, which marked the beginning of the space age. Since then, space exploration has become an important field of study and human activity.

### Section 2: Key Principles of Space Law

Space law is based on several key principles, including:

1. The common heritage of mankind: This principle states that outer space and its resources are the property of all nations and should be used for the benefit of all.

2. Non-appropriation: Nations cannot claim ownership of any part of outer space or its resources.

3. Non-interference: Nations should not interfere with each other's space activities.

4. Safety and security: Nations must ensure the safety and security of their space activities and avoid harming others.

5. Liability: Nations are responsible for the damages caused by their space activities.

### Section 3: International Organizations and Space Law

Several international organizations play a crucial role in regulating space activities. The most important of these organizations is the United Nations (UN). The UN has established several treaties and conventions related to space law, including the Outer Space Treaty (OST) and the Rescue Agreement.

Another important organization is the International Telecommunication Union (ITU), which regulates satellite communication and spectrum management.

### Section 4: Challenges of Regulating Space Activities

Regulating space activities presents several challenges, including:

1. Jurisdiction: Determining which nation has jurisdiction over an incident or activity in space.

2. Resource exploitation: Balancing the benefits of resource exploitation with the common heritage of mankind principle.

3. Space debris: Managing the growing problem of space debris, which can pose a threat to space activities and satellites.

4. Space tourism: Ensuring the safety of space tourists and addressing liability issues.

### Glossary

- Space law: A branch of international law that deals with activities in outer space.
- Common heritage of mankind: The principle that outer space and its resources belong to all nations and should be used for their collective benefit.
- Non-appropriation: The principle that nations cannot claim ownership of any part of outer space or its resources.
- Non-interference: The principle that nations should not interfere with each other's space activities.
- Safety and security: The principle that nations must ensure the safety and security of their space activities and avoid harming others.

The technique, also called fracking, has been widely used in the last decade to unlock vast new fields of natural gas, but drillers only recently figured out how to release large quantities of oil, which flows less easily through rock than gas. As evidence mounts that fracking poses risks to water supplies, the federal government and regulators in various states are considering tighter regulations on it.

The oil industry says any environmental concerns are far outweighed by the economic benefits of pumping previously inaccessible oil from fields that could collectively hold two or three times as much oil as Prudhoe Bay, the Alaskan field that was the last great onshore discovery. The companies estimate that the boom will create more than two million new jobs, directly or indirectly, and bring tens of billions of dollars to the states where the fields are located, which include traditional oil sites like Texas and Oklahoma, industrial stalwarts like Ohio and Michigan and even farm states like Kansas.

“It’s the one thing we have seen in our adult lives that could take us away from imported oil,” said Aubrey McClendon, chief executive of Chesapeake Energy, one of the most aggressive drillers. “What if we have found three of the world’s biggest oil fields in the last three years right here in the U.S.? How transformative could that be for the U.S. economy?”

textbook:
Lesson: Fracking and Its Economic Benefits

Introduction:
Fracking is a technique used to extract natural gas and oil from underground rock formations. It involves injecting high-pressure water, sand, and chemicals into the ground to crack open the rock and release the gas or oil trapped inside. This technique has been widely used in the last decade and has led to the discovery of vast new fields of natural gas and oil. In this lesson, we will explore the economic benefits of fracking and how it can create job opportunities and bring in revenue for states where the fields are located.

Section 1: Understanding Fracking
- What is fracking?
- How does fracking work?
- Why is fracking controversial?

Section 2: Economic Benefits of Fracking
- How does fracking create jobs?
- How does fracking bring in revenue for states?
- Which states benefit the most from fracking?

Section 3: Critical Thinking Questions
- Are the economic benefits of fracking worth the risk of environmental damage?
- Can fracking coexist with environmental protection?
- Should the government regulate fracking more strictly?

Glossary:
- Fracking: A technique used to extract natural gas and oil from underground rock formations.
- Natural Gas: A colorless, odorless gas that is used to heat homes, fuel engines, and generate electricity.
- Oil: A black or dark brown liquid that is formed from the remains of dead plants and animals and is used to make gasoline, diesel fuel, and many other products.

Conclusion:
Fracking has been a topic of debate for many years due to its potential environmental impact. However, it is undeniable that the economic benefits of fracking are significant. The extraction of natural gas and oil through fracking creates job opportunities and brings in revenue for states where the fields are located. As with any technology or process, there are pros and cons to consider. It is essential to weigh the economic benefits against the potential risks to the environment. By understanding the principles behind fracking and evaluating the evidence, we can make informed decisions about the future of energy production.

b. Project management
c. Public policy analysis
d. Environmental impact assessments

## Section 3: Real-World Examples

Let's consider an example of BCA in the context of a school district. The district is considering building a new school building to accommodate the growing student population. The cost of construction is estimated at $10 million, and the annual operating costs are expected to be $500,000. On the other hand, the district expects the new building to increase property values in the area, resulting in additional tax revenue.

1. What are the benefits of building the new school building?
a. Increased capacity for student enrollment
b. Improved learning environment
c. Increased property values
d. Additional tax revenue

2. What are the costs of building the new school building?
a. Construction costs ($10 million)
b. Annual operating costs ($500,000)
c. Opportunity cost of not investing in other projects

By conducting a BCA, the school district can determine whether the benefits of building the new school building outweigh the costs. If the net benefits are positive, the district may decide to proceed with the project. However, if the net benefits are negative, the district may choose to invest in other areas or explore alternative solutions.

## Glossary

- Benefit cost analysis (BCA): A method used to compare the benefits and costs of different options to determine the most cost-effective solution.
- Net benefits: The difference between the total benefits and total costs of an action or decision.
- Opportunity cost: The value of the next best alternative that is forgone when choosing one option over another.

## Conclusion

Benefit cost analysis is a valuable tool for making informed decisions. By comparing the benefits and costs of different options, individuals and organizations can identify the most cost-effective solution and maximize their return on investment. As we have seen in the real-world example, BCA can be applied in various settings, including investment decisions, project management, and public policy analysis. By understanding the basics of BCA and its applications, we can make better decisions and improve our overall well-being.

In this lesson, we will explore the basics of international relations, including the roles of different actors and the importance of agreements and treaties.

**Section 1: Actors in International Relations**

There are several actors involved in international relations, including:

1. States: States are the primary actors in international relations. They are sovereign entities that have the ability to make decisions and enter into agreements with other states.

2. International Organizations: International organizations are groups of countries that work together to achieve common goals. Examples include the United Nations, the World Bank, and the European Union.

3. Non-Governmental Organizations (NGOs): NGOs are groups that operate independently of government control. They often focus on specific issues such as human rights, environmental protection, or poverty alleviation.

4. Individuals: Individuals can also play a role in international relations through their actions and opinions. For example, people can influence their government's policies through protests and petitions.

**Section 2: Agreements and Treaties**

Agreements and treaties are important tools in international relations. They help countries work together to achieve common goals and resolve conflicts. Some common types of agreements include:

1. Trade Agreements: Trade agreements help countries trade goods and services with each other. They can also include rules for fair trade practices and environmental standards.

2. Security Agreements: Security agreements help countries protect themselves from threats such as terrorism or military attack. They can include mutual defense pacts or agreements to share intelligence information.

3. Human Rights Agreements: Human rights agreements aim to protect the basic rights of all people, regardless of their nationality or location. Examples include the Universal Declaration of Human Rights and the Convention on the Rights of the Child.

**Section 3: Practical Examples**

Let's look at a practical example of international relations in action. Suppose Country A and Country B have been having disagreements over a shared river. They decide to work together to find a solution.

1. First, they send representatives to meet and discuss the issue. These representatives may be from their government or from an international organization.

2. They may decide to enter into a trade agreement to promote economic cooperation and increase their dependence on each other.

3. They may also sign a security agreement to ensure that neither country attacks the other over the river dispute.

**Conclusion**

In conclusion, international relations involve complex interactions between many different actors. Agreements and treaties are essential tools for promoting cooperation and resolving conflicts. By understanding these concepts, we can better appreciate the importance of international relations and the challenges that arise in our globalized world.

Q:

Getting desired data from a CVPixelBuffer Reference

I have a program that views a camera input in real-time and gets the color value of the middle pixel.  I use a captureOutput: method to grab the CMSampleBuffer from an AVCaptureSession output (which happens to be read as a CVPixelBuffer) and then I grab the rgb values of a pixel using the following code:
// Get a CMSampleBuffer's Core Video image buffer for the media data
CVImageBufferRef imageBuffer = CMSampleBufferGetImageBuffer(sampleBuffer);
// Lock the base address of the pixel buffer
CVPixelBufferLockBaseAddress(imageBuffer, 0);

// Get the number of bytes per row for the pixel buffer
size_t bytesPerRow = CVPixelBufferGetBytesPerRow(imageBuffer);
// Get the pixel buffer width and height
size_t width = CVPixelBufferGetWidth(imageBuffer);
size_t height = CVPixelBufferGetHeight(imageBuffer);
unsigned char* pixel = (unsigned char *)CVPixelBufferGetBaseAddress(imageBuffer);

NSLog(@"Middle pixel: %hhu", pixel[((width*height)*4)/2]);
int red = pixel[(((width*height)*4)/2)+2];
int green = pixel[(((width*height)*4)/2)+1];
int blue = pixel[((width*height)*4)/2];
int alpha = 1;

UIColor *color = [UIColor colorWithRed:(red/255.0f) green:(green/255.0f) blue:(blue/255.0f) alpha:(alpha)];

I though that formula ((width*height)*4)/2 would get me the middle pixel, but it gives me the top middle pixel of the image.  I am wondering what formula I would need to use to access the pixel in the middle of the screen.  I'm kind of stuck because I don't really know the internal structure of these pixel buffers.
In the future I would like to grab the 4 middle pixels and average them for a more accurate color reading, but for now I would just like to get an idea how these things work.

A:

The main problem with your formula for locating the middle pixel is that it only works for an uneven number of scan lines. If you have an even number, it picks the first pixel on the scan line just below the middle. That's the middle left pixel. Since the iPhone video frames are rotated by 90 degree, this pixel is in reality the top middle pixel.
So a better formula for locating the middle pixel is:
(height / 2) * bytesPerRow + (width / 2) * 4

Lesson: Getting Desired Data from a CVPixelBuffer Reference

Introduction:

In this lesson, we will learn how to get desired data from a CVPixelBuffer Reference. We will cover the following topics:

1. What is a CVPixelBuffer?
2. How to get a CVPixelBuffer Reference?
3. How to lock the base address of the pixel buffer?
4. How to get the number of bytes per row for the pixel buffer?
5. How to get the pixel buffer width and height?
6. How to get the middle pixel value?
7. How to get RGB values of a pixel?
8. How to convert RGB values to UIColor?

What is a CVPixelBuffer?

A CVPixelBuffer is a class that represents a pixel buffer that can hold pixel data in various formats, such as grayscale or RGB. It is used to store and manipulate video frames.

How to get a CVPixelBuffer Reference?

To get a CVPixelBuffer Reference, you need to create an instance of AVAssetReader and set the asset to be read by the reader. Then, you can create a CMSampleBuffer by calling the readSampleBuffer method on the AVAssetReader. Finally, you can get the CVPixelBuffer from the CMSampleBuffer using the CMSampleBufferGetImageBuffer method.

How to lock the base address of the pixel buffer?

To lock the base address of the pixel buffer, you need to call the CVPixelBufferLockBaseAddress method with the CVPixelBufferLockBaseAddressFlags flag set to kCVPixelBufferLock_readOnly. This will return a pointer to the base address of the pixel buffer.

How to get the number of bytes per row for the pixel buffer?

To get the number of bytes per row for the pixel buffer, you need to call the CVPixelBufferGetBytesPerRow method. This will return the number of bytes per row for the pixel buffer.

How to get the pixel buffer width and height?

To get the pixel buffer width and height, you need to call the CVPixelBufferGetWidth and CVPixelBufferGetHeight methods, respectively. These methods will return the width and height of the pixel buffer.

How to get the middle pixel value?

To get the middle pixel value, you need to calculate the index of the middle pixel based on the width and height of the pixel buffer. Then, you can use the lockBaseAddress method to get the base address of the pixel buffer, cast it to a pointer to unsigned char, and access the middle pixel value.

How to get RGB values of a pixel?

To get RGB values of a pixel, you need to calculate the index of the pixel based on the width and height of the pixel buffer. Then, you can use the lockBaseAddress method to get the base address of the pixel buffer, cast it to a pointer to unsigned char, and access the RGB values of the pixel.

How to convert RGB values to UIColor?

To convert RGB values to UIColor, you need to create an instance of UIColor and pass in the R, G, and B values as arguments to the init method. For example, if you have RGB values of (255, 0, 0), you can create an instance of UIColor as follows:

UIColor *color = [UIColor colorWithRed:255/255.0 green:0/255.0 blue:0/255.0 alpha:1.0];

Conclusion:

In this lesson, we learned how to get desired data from a CVPixelBuffer Reference. We covered topics such as what is a CVPixelBuffer, how to get a CVPixelBuffer Reference, how to lock the base address of the pixel buffer, how to get the number of bytes per row for the pixel buffer, how to get the pixel buffer width and height, how to get the middle pixel value, and how to get RGB values of a pixel. We also learned how to convert RGB values to UIColor.

Q:

Coloring edges based on node label (edges connecting similar and dissimilar colored differently)

I have an undirected network of 300 nodes built based on a binary adjacency matrix. 50 nodes are labeled as minority and the rest as majority. I want to set edge colors (and attributes) based on the nodes they connect: within.mino, within.majo, and between.minomajo.
I have seen ways of coloring edges based on one of the nodes like this but this is not my problem. I also have tried this solution but couldn't adapt it to my problem.
Here is a minimal reproducible example:
library(igraph)

# making the binary matrix
set.seed(10)
m.non_sym <- matrix(sample(0:1, 7, replace=TRUE), 10, 10)

# making it symmetrical
m.lower <- lower.tri(m.non_sym)*m.non_sym
m <- m.lower + t(m.lower)
diag(m) <- 0

# making the graph
g <- m %>% graph_from_adjacency_matrix(mode="undirected")

# assigning labels
V(g)$partition <- c(rep("minority", 4),
                    rep("majority", 6))

# plotting the graph
g %>% plot(vertex.size=10,
           vertex.color=c("skyblue", "pink")[1+(V(g)$partition=="majority")],
           edge.width = 3)

I want to assign the following labels on the edges, based on to which type of node they're connected to:

A:

You can use the %--% selector to find edges that meet your conditions and the set their color. Try out:
# select edges and set color
E(g)[V(g)[partition == "minority"] %--% V(g)[partition == "minority"]]$color <- "blue" # within.mino
E(g)[V(g)[partition == "minority"] %--% V(g)[partition == "majority"]]$color <- "red" # between.minomajo
E(g)[V(g)[partition == "majority"] %--% V(g)[partition == "majority"]]$color <- "yellow" # within.majo
# plot
g %>% plot(vertex.size = 10,
           vertex.color = c("skyblue", "pink")[1 + (V(g)$partition == "majority")],
           edge.width = 3)

Instead of color, you can also use the label if you want:
E(g)[V(g)[partition == "minority"] %--% V(g)[partition == "minority"]]$label <- "within.mino"
E(g)[V(g)[partition == "minority"] %--% V(g)[partition == "majority"]]$label <- "between.minomajo"
E(g)[V(g)[partition == "majority"] %--% V(g)[partition == "majority"]]$label <- "within.majo"

g %>% plot(vertex.size = 10,
           vertex.color = c("skyblue", "pink")[1 + (V(g)$partition == "majority")],
           edge.width = 3)

Lesson: Coloring Edges Based on Node Labels

Introduction:
In this lesson, we will learn how to color edges based on the labels of the nodes they connect. We will use the igraph package in R to create a network and assign node labels. Then, we will use these labels to color the edges connecting similar and dissimilar labeled nodes differently.

Pre-Requisites:
- Basic knowledge of graph theory
- Familiarity with the igraph package in R

Materials:
- A computer with R installed
- The igraph package in R

Objectives:
- Understand the concept of coloring edges based on node labels
- Learn how to create a network using the igraph package in R
- Learn how to assign node labels to a network
- Learn how to color edges based on the labels of the nodes they connect

Lesson Plan:
1. Introduction
2. Creating a Network using the igraph Package
3. Assigning Node Labels
4. Coloring Edges Based on Node Labels
5. Practical Examples
6. Conclusion

Lesson 1: Introduction
In this lesson, we will learn about the concept of coloring edges based on node labels. We will use the igraph package in R to create a network and assign node labels. Then, we will use these labels to color the edges connecting similar and dissimilar labeled nodes differently.

Lesson 2: Creating a Network using the igraph Package
To create a network using the igraph package in R, we can use the following code:

```R
library(igraph)
# making the binary matrix
set.seed(10)
m.non_sym <- matrix(sample(0:1, 7, replace=TRUE), 10, 10)
# making it symmetrical
m.lower <- lower.tri(m.non_sym)*m.non_sym
m <- m.lower + t(m.lower)
diag(m) <- 0
# making the graph
g <- m %>% graph_from_adjacency_matrix(mode="undirected")
```

This code creates a 10x10 binary matrix, makes it symmetrical, and then creates a graph from the adjacency matrix using the `graph_from_adjacency_matrix()` function from the igraph package.

Lesson 3: Assigning Node Labels
To assign node labels to a network, we can use the `V()` function in the igraph package. This function returns a vector containing the vertices of the graph. We can then assign labels to each vertex using the `partition` variable.

```R
# assigning labels
V(g)$partition <- c(rep("minority", 4),
                    rep("majority", 6))
```

In this code, we assign the labels "minority" and "majority" to the first four and last six vertices of the graph, respectively.

Lesson 4: Coloring Edges Based on Node Labels
To color edges based on the labels of the nodes they connect, we can use the `edge_colors()` function in the igraph package. This function takes a vector of colors as an argument and assigns those colors to the edges of the graph.

```R
# coloring edges based on node labels
g <- g %>% add_edges(from=V(g)[V(g)$partition=="minority", ],
                     to=V(g)[V(g)$partition=="majority", ],
                     color=c("#FF0000", "#00FF00"))
```

In this code, we create a new graph by adding edges between the minority and majority vertices. We assign the colors red and green to the edges based on the labels of the nodes they connect.

Lesson 5: Practical Examples
We can use the following practical example to understand the concept of coloring edges based on node labels:

Suppose we have a network of 100 nodes, with 50 nodes labeled as minority and the rest as majority. We want to color the edges connecting the minority and majority nodes differently. We can use the `edge_colors()` function in the igraph package to achieve this.

```R
# making the binary matrix
set.seed(10)
m.non_sym <- matrix(sample(0:1, 100, replace=TRUE), 100, 100)
# making it symmetrical
m.lower <- lower.tri(m.non_sym)*m.non_sym
m <- m.lower + t(m.lower)
diag(m) <- 0
# making the graph
g <- m %>% graph_from_adjacency_matrix(mode="undirected")
# assigning labels
V(g)$partition <- c(rep("minority", 50),
                    rep("majority", 50))
# coloring edges based on node labels
g <- g %>% add_edges(from=V(g)[V(g)$partition=="minority", ],
                     to=V(g)[V(g)$partition=="majority", ],
                     color=c("#FF0000", "#00FF00"))
```

In this code, we create a network with 100 nodes, 50 labeled as minority and the rest as majority. We then assign the labels to the vertices using the `partition` variable. Finally, we color the edges connecting the minority and majority nodes differently using the `edge_colors()` function.

Lesson 6: Conclusion
In this lesson, we learned how to color edges based on the labels of the nodes they connect using the igraph package in R. We covered the basics of creating a network, assigning node labels, and coloring edges based on node labels. We also provided a practical example to demonstrate the concept. By the end of this lesson, you should be able to apply the skills gained to new problems involving edge coloring based on node labels.

Lesson: Introduction to Decision Support Systems in Forest Management

## Section 1: Theoretical Concepts

A decision support system (DSS) is a computer-based tool that helps decision makers to choose the best possible solution from multiple alternatives. In the context of forest management, DSS can be used to optimize resource allocation, minimize environmental impacts, and maximize economic returns.

## Section 2: Practical Examples

Let's consider a hypothetical forest management scenario. A forest owner wants to determine the best time to harvest timber from a plot of land. The owner has two options: either they harvest the timber in the spring or in the fall. The owner must take into account factors such as weather conditions, market demand, and transportation costs. A DSS can help the owner to analyze these factors and make an informed decision about the optimal time to harvest the timber.

## Section 3: Real-World Scenarios

In the real world, DSS are used by forest managers to make complex decisions related to forest planning, conservation, and sustainability. For example, a forest manager may use a DSS to determine the most efficient way to allocate resources for forest fire prevention. The DSS can analyze data on weather patterns, topography, and vegetation density to identify areas that are most at risk for forest fires. Based on this information, the manager can allocate resources such as firefighters, equipment, and funding to the areas that need it most.

## Glossary
- Decision Support System (DSS): A computer-based tool that helps decision makers to choose the best possible solution from multiple alternatives.
- Forest Management: The practice of managing forests for multiple purposes, including timber production, conservation, and sustainability.
- Optimization: The process of finding the best solution from among all possible solutions.

## Conclusion

In conclusion, DSS are powerful tools that can help forest managers to make informed decisions that optimize resource allocation, minimize environmental impacts, and maximize economic returns. By understanding the theoretical concepts, analyzing practical examples, and applying real-world scenarios, students can gain a deeper understanding of how DSS can be used to improve forest management practices.

Solid-state characterization and dissolution properties of Fluvastatin sodium salt hydrates.
The present study reports the solid-state properties of Fluvastatin sodium salt crystallized from different solvents for comparison with crystalline forms of the commercially available raw material and United States Pharmacopeia (USP) reference standard. Fluvastatin (FLV) samples were characterized by several techniques; such as X-ray powder diffractometry, differential scanning calorimetry, thermogravimetry, liquid and solid-state nuclear magnetic resonance spectroscopy, diffuse reflectance infrared Fourier transform spectroscopy, and scanning electron microscopy. In addition, intrinsic dissolution rate (IDR) of samples was performed in order to study the influence of crystalline form and other factors on rate and extent of dissolution. Three different forms were found. The commercial raw material and Fluvastatin-Acetonitrile (ACN) were identified as "form I" hydrate, the USP reference standard as "form II" hydrate and an ethanol solvate which presented a mixture of phases. Form I, with water content of 4%, was identified as monohydrate.

365 by Whole Foods, the new grocery store concept with a focus on lower prices, opened in Los Angeles’ Silver Lake neighborhood in May 2016. While many would assume that the shopping experience at 365 is comparable to that at Whole Foods, just one visit will prove that isn’t the case.

So, why did Whole Foods do something so radical and create a new grocery store for younger adults?

The 28,000-square-foot Silver Lake flagship store is designed with Millennials in mind, complete with low prices, high-tech amenities and the very notable absence of customer service. Inside the store, customers can sip on a cup of tea from the hot tea-dispensing TeaBOT machine (yes, young folks are into tea), food orders can be placed on a smartphone application, and booze can be identified and properly paired with fresh food on a tablet. So, why did Whole Foods do something so radical and create a new grocery store for younger adults? The answer is simple: young people haven’t learned to care about Whole Foods yet. As a Shook Kelley Los Angeles college intern, I am still figuring out the grocery stores I like best and waiting to see who might win me over. Before my trip to 365, Whole Foods wasn’t even in the running. Now it is, not just because of the quality of their product, but because of their excellence in delivering a quality shopping experience.

365 responds to Millennials with tighter budgets, because young adults are just starting their careers and many are saddled with student loan debt. Meanwhile, the cost of living, especially in the major urban areas that Millennials find most appealing, like Los Angeles, are outpacing any visible rise in income. To a certain degree, this has always been a predicament for younger adults just starting out. But one other difference today is the competitive environment for food retailers. Whereas in the past, traditional grocery stores could make their appeal to younger adults and their young families, today there is a bigger variety of store options, not to mention QSR, food-to-go and online services. The idea of Whole Foods is compelling, but brands like Trader Joe’s and Aldi are far less expensive; while they don’t offer the same quality in produce or the same variety in organic goods, they more than make up for it in international discoveries, easy to prep meals and food culture exploration. In order to fight the “Whole Paycheck” perception, whether true or not, Whole Foods has decided to simply start an entirely new food destination brand (which could have more fittingly been called “Half Paycheck”).

Almost exclusively selling the Whole Foods 365 private label products, the company has taken a minimalistic approach in order to keep prices down.

Walking through the automatic sliding doors at the 365 prototype store in Silver Lake, it’s clear that Whole Foods is trying to connect with a younger audience. From signs encouraging headphone-wearing youth to “rock out with us on Spotify,” to the bright orange “Come On In” sign that leads you into a controlled temperature room that’s perfect for storing fresh produce, tremendous efforts have been made to have 365 stand alone and be completely different from the standard Whole Foods store—or any other food retailer, for that matter. Almost exclusively selling the Whole Foods 365 private label products, the company has taken a minimalistic approach in order to keep prices down.

Whole Foods’ decision to mostly sell their private label food products was strategic, and timely. In most grocery stores, the most “desired” product tends to be the national name brands, and it takes removing that choice to realize that sometimes the private label brand is just as good, if not better. 365’s colorful logo for their private label seems to be plastered across just about every can or bag in the marketplace. From colorful blue corn tortilla chips to organic guacamole, it’s clear that Whole Foods did not sacrifice their reputation for flavor or culture in the making of their private label products. According to Mintel’s 2015 “Private Label Goods: What’s Driving Purchase?” report, 42 percent of Millennials (age 19-37) actually consider store brand food products more innovative than name brand CPG products. In addition, more than one third (37%) of United States shoppers today are preferring to buy store brand products over name brand products. The approach at 365 mimics the success of other smaller format stores like Trader Joe’s, almost solely focused on offering private label products in order to build the retailer’s brand.

It’s clear that Whole Foods set out to create a new kind of grocery store that, like Millennials, is on-the-go and quick to adapt.

While 365 lacks the high-end grocery store vibe of a traditional Whole Foods marketplace, it has a colorful, open design that is sure to make everyone’s shopping experience a pleasure. Despite the lack of customer service (a strategic move that not only cuts cost out of the operation, but is acceptable in an era of Millennials’ technology dependency), the store feels easy to navigate and fun to shop at. It’s clear that Whole Foods set out to create a new kind of grocery store that, like Millennials, is on-the-go and quick to adapt. The store itself is proof that while retail and how we shop changes with time, the need to convene remains the same. All 365 needs now is a barber to trim those hipster bears and a modest vinyl record selection at the front of the store, and the kids will never want to shop anywhere else.

Functional interaction of dopamine and glutamate in the nucleus accumbens in the regulation of locomotion.
The interaction of dopamine and glutamate in the nucleus accumbens in the regulation of locomotion was investigated. Microinjection of N-methyl-D-aspartic acid (NMDA, a glutamatergic NMDA receptor agonist) or alpha-amino-3-hydroxy-5-methylisoxazole-4-propionate (AMPA, a quisqualic receptor agonist which is a glutamatergic non-NMDA receptor agonist) into the nucleus accumbens caused a substantial increase in locomotor activity. This increase in locomotor activity was significantly reduced by prior administration of the dopamine D2 agonist quinpirole, but not the D1 agonist, SKF 38393, into the same brain sites. The reduction in locomotion produced by quinpirole was dose dependent. Eight days after the ventral tegmental area was lesioned with 6-hydroxydopamine to destroy the dopamine projection and the axon terminals of the mesolimbic dopamine neurons in nucleus accumbens, the hyperkinetic effects produced by injections of NMDA and AMPA into the nucleus accumbens were substantially reduced. These results suggested that the glutamate agonist induced locomotion is mediated by dopamine. Thus, it appears that NMDA- or AMPA-induced locomotion is due to the activation of glutamate receptors on the mesolimbic dopamine terminals in the nucleus accumbens which release dopamine and subsequently increase locomotion.

Lesson: The Interaction of Dopamine and Glutamate in the Regulation of Locomotion

Introduction:
In this lesson, we will explore the functional interaction of dopamine and glutamate in the regulation of locomotion. We will investigate the role of these neurotransmitters in the nucleus accumbens and how they contribute to movement.

Section 1: The Nucleus Accumbens

The nucleus accumbens is a part of the brain that plays a crucial role in reward, motivation, and addiction. It is located in the basal ganglia and is involved in the regulation of movement.

Section 2: The Interaction of Dopamine and Glutamate

Microinjection of N-methyl-D-aspartic acid (NMDA) or alpha-amino-3-hydroxy-5-methylisoxazole-4-propionate (AMPA) into the nucleus accumbens increases locomotor activity. However, this increase is significantly reduced by prior administration of the dopamine D2 agonist quinpirole. This suggests that dopamine plays a role in the regulation of locomotion in the nucleus accumbens.

Section 3: The Role of Dopamine and Glutamate in Locomotion

Dopamine and glutamate interact in the nucleus accumbens to regulate locomotion. Dopamine is released by neurons in the ventral tegmental area (VTA) and projects to the nucleus accumbens. Glutamate is released by neurons in the nucleus accumbens itself. These neurotransmitters work together to modulate movement.

Section 4: The Importance of Dopamine and Glutamate in Locomotion

Understanding the interaction of dopamine and glutamate in the nucleus accumbens is essential for understanding the neural basis of movement. This knowledge can help us develop treatments for movement disorders such as Parkinson's disease, which is characterized by a lack of dopamine in the VTA.

Conclusion:
In this lesson, we have explored the interaction of dopamine and glutamate in the regulation of locomotion in the nucleus accumbens. We have learned about the role of these neurotransmitters in movement and their importance in understanding the neural basis of movement. By understanding the interaction of dopamine and glutamate in the nucleus accumbens, we can develop treatments for movement disorders and improve our understanding of the brain's role in movement.

It is a slice of life that proves that even in the 2nd century AD, language learning involved pointless sentences that nobody ever used – sort of a Graeco-Roman Egyptian version of “La plume de ma tante est jaune,” or (one that has stuck in my mind all these many years after first learning German), “Das aufschnieden des Stieffels ist zu vermeiden.” (“The cutting off of boots is to be avoided.)
