text: A three-way catalyst containing an oxygen occludable material has conventionally been known as one of catalysts that are interposed in the exhaust systems of vehicles driven by the power of gasoline. A three-way catalyst simultaneously promotes reduction of oxygen nitride (NOx), oxidization of hydrocarbon (HnCm), and oxidization of carbon monoxide (CO) in an atmosphere close to the stoichiometric air-fuel ratio. An oxygen occludable material is a promotor having characteristics that adsorbs oxygen under a lean atmosphere, and releases the oxygen occluded during lean running under a rich atmosphere. Examples of an oxygen occludable material are Ceria (CeO2), Ceria-Zirconia composite (CeO2—ZrO2), Almina-Ceria-Zirconia composite (Al2O3—CeO2—ZrO2), and composites of the above materials and second or third element components. Including the above oxygen occludable material in a catalyst easily maintain the oxygen concentration around the active site of the catalyst to the concentration near the stoichiometric air-fuel ratio. This ensures the air-fuel ratio to obtain preferable catalytic activity, so that the ability of the catalyst for purifying exhaust gas can be enhanced. The oxygen occluded on the oxygen occludable material is used in oxidization of hydrocarbon, carbon monoxide, and hydrogen (see Patent Literature 1).

Lesson: Understanding Three-Way Catalysts

**Introduction**

Three-way catalysts are essential components in modern vehicles that help reduce pollution caused by emissions. They play a crucial role in controlling the levels of nitrogen oxides (NOx), hydrocarbons (HnCm), and carbon monoxide (CO) in the exhaust system. In this lesson, we will explore the working principles of three-way catalysts, their components, and their applications.

**Section 1: What is a Three-Way Catalyst?**

A three-way catalyst is a type of catalytic converter that contains an oxygen storage catalyst (OSC) material. It is designed to promote the reduction of NOx, oxidation of HnCm, and oxidation of CO in the exhaust gases. The catalyst operates under a stoichiometric air-fuel ratio, which means that it functions optimally when the air-to-fuel ratio is around 14.7:1.

**Section 2: Components of a Three-Way Catalyst**

The main components of a three-way catalyst are the active sites, which are made up of precious metals such as platinum, palladium, and rhodium. These metals promote the chemical reactions necessary for the reduction of NOx, oxidation of HnCm, and oxidation of CO. The other component is the oxygen storage catalyst (OSC) material, which is responsible for storing and releasing oxygen as needed. Examples of OSC materials include ceria (CeO2), ceria-zirconia composite (CeO2-ZrO2), alumina-ceria-zirconia composite (Al2O3-CeO2-ZrO2), and composites of these materials with second or third element components.

**Section 3: How does a Three-Way Catalyst work?**

The three-way catalyst works by promoting the following chemical reactions:

1. Reduction of NOx: The active sites on the catalyst reduce NOx to nitrogen (N2) and oxygen (O2).
2. Oxidation of HnCm: The active sites oxidize HnCm to carbon dioxide (CO2) and water (H2O).
3. Oxidation of CO: The active sites oxidize CO to carbon dioxide (CO2).

The OSC material plays a crucial role in this process by storing and releasing oxygen as needed. When the engine is running lean (with more air than fuel), the OSC material adsorbs oxygen. When the engine is running rich (with more fuel than air), the OSC material releases the adsorbed oxygen, creating an optimal environment for the chemical reactions to occur.

**Section 4: Applications**

Three-way catalysts are used in vehicles that run on gasoline. They are essential in reducing pollution caused by emissions and help vehicles meet emission standards set by governments. The use of three-way catalysts has led to a significant reduction in air pollution, making the air cleaner and healthier to breathe.

**Glossary**

- Oxygen storage catalyst (OSC) material: A material that can store and release oxygen as needed. Examples include ceria (CeO2), ceria-zirconia composite (CeO2-ZrO2), alumina-ceria-zirconia composite (Al2O3-CeO2-ZrO2), and composites of these materials with second or third element components.
- Active sites: The parts of the catalyst that promote chemical reactions. They are made up of precious metals such as platinum, palladium, and rhodium.
- Chemical reactions: Processes in which substances interact and change to form new substances. In the case of three-way catalysts, the reactions involve the reduction of NOx, oxidation of HnCm, and oxidation of CO.

**Conclusion**

In conclusion, three-way catalysts are essential components in vehicles that run on gasoline. They help reduce pollution caused by emissions by promoting the reduction of NOx, oxidation of HnCm, and oxidation of CO. The three-way catalyst contains an oxygen storage catalyst (OSC) material, which stores and releases oxygen as needed. This lesson has provided an overview of the working principles of three-way catalysts, their components, and their applications.

Lesson: Introduction to Roller Skates

## Section 1: Theoretical Concepts

Roller skates are a type of recreational vehicle that allows users to glide on surfaces using wheels. They consist of a frame, bearings, and wheels. In this lesson, we will explore the different parts of roller skates and how they work together to provide a smooth and enjoyable ride.

## Section 2: Questions and Answers

**Question:** What are the different parts of roller skates?

**Answer:** The different parts of roller skates include the frame, bearings, and wheels.

**Question:** How do roller skates work?

**Answer:** Roller skates work by using a combination of friction and momentum to move forward or backward. When you push off the ground with one foot, you are applying force to the wheel, which causes it to rotate and move forward. The bearings inside the wheels allow them to spin smoothly and easily, making your movement effortless.

## Section 3: Definitions of Purpose

**Definition:** Friction - The force that opposes motion between two surfaces in contact.

**Definition:** Momentum - The product of the mass and velocity of an object.

## Section 4: Practical Examples Using Mathematical Abstractions and Real-World Scenarios

Let's consider a roller skate with a mass of 20 kg and a velocity of 5 m/s. Using the formula for momentum, we can calculate the amount of force required to bring the skate to a stop:

F = (m * v) / t

Where F is the force, m is the mass, v is the velocity, and t is the time it takes to stop. If we assume it takes 1 second to stop, then:

F = (20 kg * 5 m/s) / 1 s = 100 N

This means that a force of 100 Newtons is required to bring the skate to a stop in one second.

## Section 5: Self-Debating Discussions

**Discussion:** Roller skates have been around for over 200 years. What changes have been made to their design since they were first invented?

**Answer:** Over the years, roller skates have undergone several changes in their design. One of the most significant changes was the introduction of quad skates, which have two pairs of wheels arranged in a wide configuration. This design provided more stability and control, making it easier for beginners to learn how to skate. Additionally, modern roller skates are made from lightweight materials such as aluminum and plastic, making them lighter and easier to maneuver.

## Glossary

**Friction:** The force that opposes motion between two surfaces in contact.

**Momentum:** The product of the mass and velocity of an object.

**Newtons:** A unit of force in the International System of Units.

**Quad Skates:** Roller skates with two pairs of wheels arranged in a wide configuration.

## Conclusion

In this lesson, we explored the different parts of roller skates and how they work together to provide a smooth and enjoyable ride. We also looked at the physics behind roller skates and how momentum and friction play a role in stopping them. Finally, we discussed some of the changes that have been made to roller skate design over the years. By understanding these concepts, we can appreciate the science behind this popular recreational activity and apply our knowledge to other areas of physics.


text: Hey guys,. I have 30 files full of mac addresses. What do you think would be the best way to compare all these files and output the mac addresses that show up in all 30 files to a new file. Is there a compare function? Should I read them into arrays and compare them? Any ideas would help out, I am a newbie to C but understand the basics. Thanks

textbook:
To compare all the files and output the MAC addresses that appear in all 30 files to a new file, you can use the following steps:
1. Read all the files into arrays using `fread()` function in C.
2. Compare all the arrays using a loop to find the common MAC addresses.
3. Output the common MAC addresses to a new file.
Here's an example code snippet that demonstrates this approach:
```c
#include <stdio.h>
#include <stdlib.h>
int main() {
    // Step 1: Read all the files into arrays
    FILE *files[30];
    char *mac_addresses[30][6];
    int i;
    for (i = 0; i < 30; i++) {
        files[i] = fopen("file_"i".txt", "r");
        if (files[i] == NULL) {
            printf("Error: Cannot open file %d\n", i);
            exit(1);
        }
        fread(mac_addresses[i], 6, 1, files[i]);
    }
    // Step 2: Compare all the arrays
    int j;
    for (j = 0; j < 30; j++) {
        int k;
        for (k = 0; k < 30; k++) {
            if (strcmp(mac_addresses[j], mac_addresses[k]) == 0) {
                // Common MAC address found
                // Output to a new file
                break;
            }
        }
    }
    // Step 3: Close all the files
    for (i = 0; i < 30; i++) {
        fclose(files[i]);
    }
    return 0;
}
```
In this code, we first create an array of file pointers `files` and an array of strings `mac_addresses` to store the MAC addresses read from each file. We then loop through each file, read one MAC address at a time using `fread()`, and store it in the corresponding element of `mac_addresses`.
Next, we loop through each element of `mac_addresses` and compare it with all other elements to find the common MAC addresses. If a common MAC address is found, we output it to a new file.
Finally, we close all the files used in the program.
Note that this code assumes that each file contains only one MAC address on a separate line. If your files have multiple lines or are in a different format, you may need to modify the code accordingly.

fan control on evo n800v - Portable

This is a discussion on fan control on evo n800v - Portable ; Hello
I have a compaq evo n800v on which I want to use linux.
I have install Mandrake 10.1 and all seem working except the fan
control... Acpi seem ok and seeing the dmesg, the dsdt of my laptop is
...

So I'm looking for a way to stop fan at boot time : it's active even if
the temperature is 30 degrees... if I do simple think which dont use to
many processor time (just emacs for example), the temperature never
increase and the fan is always on...

Thank you in advance for your help and sorry for my english (I'm french)

Re: fan control on evo n800v

Hi Yayel,
I cannot help a lot just give some ideas. The fan is running everytime
during boot-up even with Windows-OS. This is because the ACPI is not
activate at this time and the bios starts with a "secure" means full
speed fan mode. Otherwise you will run in trouble if you use your Evo up
to the limit, shut it down and then restart it directly (e.g. a system
crash). During boot up the CPU will die because of the released heating.
This is the reason, that during boot up th fan run at full speed to be
sure everything goes fine. However, after starting ACPI it should detect
the CPU temperature and decrease the fan-speed.

I used a Suse-Live CD 9.2. and it works well with it (Evo 800w). Suse
announced better ACPI-support. You may give it a try.

on my compaq presario 2825ea (which uses the same bios as the evo n800v)
with Debian sarge I use a script /etc/init.d/fan-switchoff:

which is linked to /etc/rcS.d/S71fan-switchoff. I don't use ACPI
modules, all is compiled into the kernel. Otherwise you have to load the
"fan" and "thermal" module before running this script. Also the
directory names in /proc/acpi/fan/ may be something else.
For SuSE you place these code lines into the script /etc/init.d/boot.local.

source: minipile

textbook:
tly. The fan control is not activated until the system reaches a
certain temperature. So if you are running a light load on the system,
the fan may not kick in. However, once the temperature rises, the fan
will start to run at full speed to cool down the system.

To control the fan speed, you can use the BIOS or the ACPI driver. The
BIOS provides a basic fan control feature that allows you to set the
fan speed to low, medium, or high. The ACPI driver provides more
advanced fan control options that allow you to set the fan speed
manually or automatically based on the system temperature.

To set up the fan control using the BIOS, follow these steps:

1. Power on the computer and enter the BIOS setup by pressing the
   appropriate key during the boot process.
2. Navigate to the "Fan Control" menu and select the fan you want to
   control.
3. Set the fan speed to "Low", "Medium", or "High" depending on your
   preference.
4. Save and exit the BIOS setup.

To set up the fan control using the ACPI driver, follow these steps:

1. Open a terminal window and log in as root.
2. Install the ACPI driver using the following command:
   ```
   apt-get install acpi-fan-control
   ```
3. Configure the fan control using the following command:
   ```
   acpi_fan=on
   ```
4. Restart the system to apply the changes.

Once you have set up the fan control, you can monitor the system
temperature using the "lm_sensors" command. If the temperature
rises above a certain threshold, the fan will start to run at full
speed to cool down the system.

In conclusion, to control the fan speed on your evo n800v, you can use
the BIOS or the ACPI driver. The BIOS provides basic fan control options,
while the ACPI driver provides more advanced fan control options. You
can also monitor the system temperature using the "lm_sensors" command
to ensure that the fan is running when needed.

## Lesson: Finding the Best Deal on a New Car
### Section 1: Introduction
In this lesson, we will learn how to find the best deal on a new car. We will cover the following topics:
- Understanding the car buying process
- Researching different makes and models
- Negotiating with dealerships
### Section 2: Understanding the Car Buying Process
The car buying process can be overwhelming, but by breaking it down into smaller steps, it becomes much easier. Here are the steps involved in buying a new car:
1. Determine your needs: Before you start shopping for a new car, you need to determine what you need. Do you need a car with a lot of space, or do you prefer a smaller, more fuel-efficient vehicle?
2. Research different makes and models: Once you know what you need, you can start researching different makes and models that fit your needs. You can use online resources like Consumer Reports or Edmunds to compare different cars.
3. Find local dealerships: Once you have narrowed down your choices, you can start looking for local dealerships that carry the cars you are interested in.
4. Test drive the cars: Once you have found a few dealerships that carry the cars you are interested in, you can schedule test drives to see how each car feels.
5. Negotiate the price: After you have test driven the cars, you can start negotiating the price with the dealerships.
### Section 3: Negotiating with Dealerships
Negotiating with dealerships can be tricky, but there are some tips that can help you get the best deal possible. Here are some tips for negotiating with dealerships:
1. Know your budget: Before you start negotiating, you need to know how much you can afford to spend. This will help you avoid wasting time with dealerships that don't have cars within your price range.
2. Be prepared to walk away: If the dealership isn't willing to meet your price, be prepared to walk away. There are plenty of other dealerships out there, so you don't have to settle for a bad deal.
3. Get pre-approved for financing: If you already have financing in place, you can negotiate with the dealership from a position of strength. This means that you won't have to take the dealership's financing, which could come with higher interest rates.
### Section 4: Conclusion
By following these steps, you can find the best deal on a new car. Remember to be patient, do your research, and be prepared to walk away if the dealership isn't willing to meet your needs. With a little patience and effort, you can get the car you want at a price you can afford.

Dissection of sigma(E)-dependent cell lysis in Escherichia coli: roles of RpoE regulators RseA, RseB and periplasmic folding catalyst PpiD.
To understand the mechanism of sigma(E)-dependent cell lysis, we examined the consequences of deletion derivatives of rpoE regulators rseA, rseB and rseC on sigma(E) transcription, on levels of free versus membrane-bound sigma(E) and on OMP-biogenesis limiting factor(s) that could impact cell lysis. RT-PCR showed that individual nonpolar DeltarseA and DeltarseB increased the rpoE expression to varying extents, with pronounced induction in DeltarseA. Significantly the ratio of soluble (free) versus membrane-bound form of RpoE increased in DeltarseA, however without increase of its total amount, unraveling furthermore complexity in RpoE regulation. Significant characteristics of cell lysis, accompanied by a severe reduction in the levels of periplasmic OMP-folding factor (PpiD), were observed in DeltarseA. The cell-lysis phenotype of DeltarseA was suppressed by either rseA or ppiD plasmids, but neither by rseB nor by rseC clones. However, the cell lysis of the wild-type strain was almost completely repressed not only by the rseA clone but also by the rseB clone, suggesting RseB might be limiting in vivo. Thus, increase in the ratio of free sigma(E) in rseA mutants with a concomitant reduction in PpiD levels can account for sigma(E)-dependent lysis in concert with a potential role of small RNAs on the lysis process.

Lesson: Understanding the Mechanism of Cell Lysis in Bacteria

Introduction:
Cell lysis is the process by which bacteria break open other cells, often as part of their natural defense mechanisms. In this lesson, we will explore the mechanism of sigma(E)-dependent cell lysis in Escherichia coli and the roles of RpoE regulators RseA, RseB, and periplasmic folding catalyst PpiD.

Section 1: Understanding Sigma(E) Transcription

Sigma(E) is a protein that plays a crucial role in the regulation of gene expression in bacteria. It is responsible for the transcription of genes involved in the response to environmental stress. In E. coli, sigma(E) is activated by the RpoE protein, which binds to DNA and recruits sigma(E) to the promoter region of target genes.

Question: What is sigma(E) and what is its role in gene expression?
Answer: Sigma(E) is a protein that regulates gene expression in bacteria during times of environmental stress. It is responsible for the transcription of genes that help the bacteria adapt to the stress.

Question: How does RpoE activate sigma(E)?
Answer: RpoE binds to DNA and recruits sigma(E) to the promoter region of target genes, allowing them to be transcribed.

Section 2: The Role of RpoE Regulators RseA, RseB, and RseC

RseA, RseB, and RseC are proteins that regulate the activity of sigma(E). They help control when and where sigma(E) is active, ensuring that the right genes are expressed at the right time.

Question: What is the role of RseA, RseB, and RseC in the regulation of sigma(E)?
Answer: RseA, RseB, and RseC are proteins that help control the activity of sigma(E), ensuring that the right genes are expressed at the right time.

Question: How do RseA, RseB, and RseC regulate sigma(E)?
Answer: RseA, RseB, and RseC interact with RpoE, either stabilizing or destabilizing it, depending on the conditions. This affects the activity of sigma(E), allowing it to be active or inactive as needed.

Section 3: The Role of Periplasmic Folding Catalyst PpiD

PpiD is a protein that helps fold other proteins in the periplasmic space of the cell. It is essential for proper cell function and survival. In E. coli, PpiD is involved in the folding of outer membrane proteins (OMPs), which are necessary for maintaining the integrity of the cell membrane.

Question: What is the role of PpiD in cell function and survival?
Answer: PpiD is a protein that helps fold other proteins in the periplasmic space of the cell. It is essential for proper cell function and survival, particularly in the folding of outer membrane proteins (OMPs).

Question: How does PpiD contribute to cell lysis in E. coli?
Answer: When there is a significant reduction in the levels of PpiD, as seen in DeltarseA, the folding of OMPs is disrupted, leading to cell lysis.

Conclusion:
In this lesson, we explored the mechanism of sigma(E)-dependent cell lysis in E. coli and the roles of RpoE regulators RseA, RseB, and periplasmic folding catalyst PpiD. We learned about the importance of sigma(E) in gene expression and the role of RseA, RseB, and RseC in regulating its activity. Finally, we discussed the role of PpiD in cell function and survival and how its absence can lead to cell lysis.

Glossary:
- Sigma(E): a protein that regulates gene expression in bacteria during times of environmental stress
- RpoE: a protein that activates sigma(E) and binds to DNA
- RseA, RseB, and RseC: proteins that regulate the activity of sigma(E)
- Periplasmic space: the space between the cell membrane and the cytoplasm
- Outer membrane proteins (OMPs): proteins that are embedded in the outer membrane of the cell

Latest Developments, July 22

A new Médecins Sans Frontières report suggests a number of major pharmaceutical companies will no longer provide antiretrovirals at discounted prices to middle-income countries, including ones with large numbers of people living with HIV, such India, Brazil and Thailand. And while Health Global Access Project’s Brook Baker praises Gilead Sciences for recently becoming the first drug-maker to join the Medicines Patent Pool (MPP) that aims to improve access to affordable HIV/AIDS treatments in poor countries, he argues the move may not have been as philanthropic as it might seem. The agreement excludes many “middle-income countries with a high HIV-burden” and “of the 111 countries included in the geographical scope of the tenofovir MPP license, Gilead has patent applications pending or granted in only 2 of the licensed countries, India and Indonesia.”

In other patent news, World Intellectual Property Organization delegates have wrapped up a week of meetings without completing drafts of treaties to protect genetic resources, traditional knowledge and folklore. A representative of indigenous peoples expressed concern that their voices were not being sufficiently heard.

Britain’s Macmillan Publishers has agreed to a hefty fine for bribes its education division paid in Africa in the hopes of securing contracts. And a confidential government memo dating from 2008 has revealed Canada’s asbestos industry, which critics say endangers the health and lives of people in the handful of poor countries which still import the substance, may be on its last legs due to dwindling reserves.

Somalia’s Al-Shabab militants, who control much of the country, are still blocking a number of aid agencies despite a recent announcement to the contrary and have called the UN’s declaration of famine “pure propaganda” even though the international organization has laid out the specific criteria it uses to make such assessments. The UN secretary general has written a plea for the world community to help the Somali famine’s victims, “the vast majority of them women and children.” Indeed, the photo accompanying the LA Times piece notwithstanding, more than 80 percent of those fleeing Somalia are women and children. This fact has prompted Al Jazeera to ask where the men are, with some suggesting they are being forced to fight in the country’s civil war. Meanwhile, the Guardian’s John Vidal blames the famine, in part, on what he calls an “insidious war” against pastoralists who “produce more and better quality meat and generate more cash per hectare than “modern” Australian and US ranches” but are being squeezed out “by large-scale farming, the expansion of national parks, and game reserves and conservation.”

Al Jazeera also asks if this week’s UN Security Council statement on the threat to global security posed by climate change is “a real opportunity to achieve significant results or an attempt to divert attention from the root causes of the problem and away from the countries that cause global warming and distribute the burden evenly on world nations.”

Council on Foreign Relations president Richard Haass proposes a so-called “restoration” doctrine, by which he means “a U.S. foreign policy based on restoring this country’s strength and replenishing its resources—economic, human and physical.” He says the idea is very different from isolationism in that it involves carrying out an “active foreign policy.” But restoration would mean engaging in “fewer wars of choice” abroad, such as those fought in Vietnam, Iraq and Libya, and making smart cuts to discretionary spending at home. Haass sees restoration as a short-term objective that could lay the groundwork for what he believes should be America’s real foreign policy goal: “integration, which aims to develop rules and institutions to govern international relations and persuade other major powers to see that these rules are followed.”

Reflecting on a new report entitled “Resource Scarcity, Fair Shares and Development,” Oxfam’s Duncan Green argues that both the left and the right argue away the idea of resource limits in their own way. He also says there is an important distinction between the “new scarcity” of planetary capacity and the largely local and socially determined ‘old scarcity’ that has always left poor people on the outside looking in. In his view, most of the scarcities are primarily local and, as a result, “we should be careful about lumping them all together or going too global, especially when it comes to solutions.”

Lesson: The Importance of Access to Affordable Medicines

Introduction:
Access to affordable medicines is a fundamental right for everyone, regardless of their socioeconomic status. However, in reality, this is not always the case. Many people, particularly those living in low-income countries, struggle to obtain the medicines they need to treat their illnesses. In this lesson, we will explore the importance of access to affordable medicines and discuss the challenges that people face in obtaining them.

Core Value:
The core value of this lesson is the importance of access to affordable medicines for all people. We will discuss why this is a fundamental right and how it can impact people's lives.

Section 1: Introduction to Access to Affordable Medicines

Topic 1: Why is access to affordable medicines important?
Access to affordable medicines is a fundamental right for everyone. It is essential for promoting health and well-being, reducing health disparities, and improving overall quality of life. Medicines are necessary for treating illnesses, managing chronic conditions, and preventing disease. When medicines are unaffordable, people may forgo treatment, which can lead to severe health complications or even death.

Topic 2: Challenges in obtaining access to affordable medicines
There are several challenges that people face in obtaining access to affordable medicines. These include:

1. High costs of medicines: Many medicines are expensive, making them unaffordable for people in low-income countries.
2. Lack of insurance coverage: Many people do not have health insurance coverage, which means they must pay for their medicines out of pocket.
3. Limited availability: Some medicines may not be available in certain regions or countries, making it difficult for people to obtain them.
4. Patent laws: Pharmaceutical companies hold patents on many medicines, which means they can set high prices and restrict access to competitors.
5. Trade agreements: Some trade agreements may limit the ability of governments to regulate the price of medicines or import cheaper versions from other countries.

Section 2: The Importance of Access to Affordable Medicines

Topic 1: Impact on health outcomes
Access to affordable medicines is essential for promoting health and well-being. When people can afford the medicines they need, they are more likely to adhere to their treatment plans, leading to better health outcomes. Conversely, when medicines are unaffordable, people may forgo treatment, which can lead to severe health complications or even death.

Topic 2: Impact on health disparities
Health disparities exist when there are differences in health outcomes between different groups of people. Access to affordable medicines can help reduce these disparities by ensuring that everyone has access to the medicines they need, regardless of their socioeconomic status.

Topic 3: Impact on overall quality of life
Access to affordable medicines is also important for improving overall quality of life. When people can manage their illnesses effectively, they are more likely to participate in daily activities and achieve their goals.

Section 3: Examples of Access to Affordable Medicines in Practice

Topic 1: The success of the Global Fund
The Global Fund is an international organization that works to fight AIDS, tuberculosis, and malaria. One of its main goals is to increase access to affordable medicines in low-income countries. Through its efforts, the Global Fund has helped to provide millions of people with access to life-saving medicines.

Topic 2: The role of generic medicines
Generic medicines are copies of brand-name medicines that have lost their patent protection. They are typically much cheaper than brand-name medicines, making them more affordable for people in low-income countries. The use of generic medicines has helped to increase access to affordable medicines worldwide.

Conclusion:
In conclusion, access to affordable medicines is a fundamental right for everyone. It is essential for promoting health and well-being, reducing health disparities, and improving overall quality of life. There are several challenges that people face in obtaining access to affordable medicines, including high costs, lack of insurance coverage, limited availability, patent laws, and trade agreements. However, through organizations like the Global Fund and the use of generic medicines, progress is being made in increasing access to affordable medicines worldwide.

Q:

Is it possible to get a "track length list" from Audacity?

I have an Audacity project (well, actually several), and I want to use it with a set of slides to create a video.  To progress the slides at the appropriate time, I need to know the exact length of each track.
I know Audacity has this information, and I can get it out by manually highlighting each track, looking at the bottom (after changing the drop-down to "Start and Length of Selection"), and then typing that into another file ... but surely there's an easier way?

A:

It would appear (sadly) that there is no way to extract the length of each track from an Audacity project.  Hopefully the Audacity team will remedy this someday, and then I can change the accepted answer to this question.

textbook:
Lesson: How to Find the Length of Each Track in an Audacity Project

## Section 1: Introduction

In this lesson, we will learn how to find the length of each track in an Audacity project. Audacity is a free, open-source audio editing software that allows users to record, edit, and mix audio files. It is a powerful tool for creating podcasts, music, and other audio projects. However, finding the length of each track in an Audacity project can be challenging. In this lesson, we will explore different methods for finding the length of each track in an Audacity project.

## Section 2: Theoretical Concepts

- Track: A track is an individual audio recording in an Audacity project. Each track contains a separate recording that can be edited independently from other tracks.
- Length: The length of a track is the duration of the recording. It is measured in seconds or minutes.

## Section 3: Practical Examples

1. Open Audacity and create a new project.
2. Import an audio file or record a new audio track.
3. Repeat steps 1 and 2 to create multiple tracks.
4. Select one of the tracks by clicking on it.
5. Look at the bottom of the Audacity window.
6. Change the drop-down menu to "Start and Length of Selection".
7. The length of the selected track will be displayed in the bottom left corner of the window.
8. Repeat steps 5-7 for each track in the project.
9. Write down or save the length of each track.

## Section 4: Self-Debating Discussions

Why is it important to know the length of each track in an Audacity project?
- Knowing the length of each track allows you to accurately synchronize your audio with visual elements such as slideshows or videos.
- If you are creating a podcast or radio show, knowing the length of each track can help you ensure that your show stays within the desired time frame.
- If you are editing a piece of music, knowing the length of each track can help you ensure that the final product is the desired length.

## Glossary

- Track: An individual audio recording in an Audacity project.
- Length: The duration of a track, measured in seconds or minutes.

## Conclusion

In this lesson, we learned how to find the length of each track in an Audacity project. We explored the theoretical concepts of tracks and length, and then applied these concepts to practical examples. We also engaged in self-debating discussions to understand the importance of knowing the length of each track in an Audacity project. By following the steps outlined in this lesson, you will be able to accurately measure the length of each track in your Audacity projects.

Children and adults who don't participate in sport or physical recreation have been of growing concern in recent times. The Australian Medical Association has recently stated that obesity is now an epidemic in Australia (End Note 1). The OECD found that the obesity rate in Australia is high compared with most countries and is projected to rise by a further 15% over the next 10 years (End Note 2). The Better Health Initiative by the Victorian Government acknowledges that inactivity, or a sedentary lifestyle, is one of the main causes of Australians gaining weight (End Note 3), making inactivity a primary area of interest.

In the following article, non-participants include adults and children who had no involvement in sport or physical recreation in either a playing or non-playing role (such as a volunteer) within the survey period, 2009-10.

Since the previous survey conducted in 2005-06, the following changes were observed:

The non-participation rates of men and women aged 25 to 34 years old have increased

The non-participation rate of men aged 15 to 17 years old has decreased

The percentage of women in one parent families who had not participated in sport or physical recreation has increased

Lone persons had the highest non-participation rate in sport and physical recreation in 2005-06, while in 2009-10 people from one parent households with dependent children had the highest non-participation rate

The non-participation rate for men who had completed Year 11 as their highest level of educational attainment has decreased.

ADULTS

Age

Women were less likely to participate in sport and physical recreation than men in all age groups. An exception was found in the 55 to 64 year age group, where men had a significantly higher non-participation rate (38%) than women (33%). The non-participation rate in sport and physical recreation was significantly higher in women aged 15 to 17 years (26%) than men of the same age (13%).

ADULT NON-PARTICIPANTS, Sport and physical recreation - By age and sex - 2009-10

State or Territory of Usual Residence

The highest non-participation rate in sport and physical recreation for women was in South Australia (37%). Men who lived in the Australian Capital Territory had a lower non-participation rate (19%) than men who lived in the other states.

ADULT NON-PARTICIPANTS, Sport and physical recreation - By state and sex - 2009-10

Country of Birth

People who were born in overseas countries had a higher non-participation rate in sport and physical recreation (40%) than people who were born in Australia (30%).

While differences in rates of non-participation between males and females for those born overseas were not significant at a national level, there were significant differences at a state level. Women had higher non-participation rates in sport and physical recreation than men in both New South Wales (44% compared with 36%) and Victoria (47% compared with 39%).

Comparing men and women who were born in non main English-speaking countries, the non-participation rate for women was significantly higher than for men in New South Wales (52% compared with 39%).

ADULT NON-PARTICIPANTS, Sport and physical recreation - By country of birth by sex - 2009-10

Labour Force

People who were not in the labour force had a significantly higher non-participation rate in sport and physical recreation (44%) than people who were employed (27%) or unemployed (31%). When comparing men and women who were not in the labour force, women had a higher non-participation rate than men (46% and 42% respectively).

The number of Australian children who are overweight or obese has risen in recent years. The ABS 2007-2008 National Health Survey (cat. no. 4364.0) found that the total proportion of overweight and obese children in Australia aged 5 to 17 years in 1995 was 21% and by 2007-2008 this figure had increased to 25%. Studies have shown that once children become obese they are more likely to stay obese into adulthood and have an increased risk of developing diseases associated with obesity (End Note 4). The absence of adequate physical activity for children is of concern.

From a one parent family where the single parent of the child was not employed

Born in non main English-speaking country.

Since the previous survey conducted in 2006, the following changes were found:

Girls in New South Wales have become less active, as their non-participation rate increased significantly from 42% in 2006 to 50% in 2009

Conversely, girls living in Victoria have become more active, with their non-participation rate having decreased from 44% in 2006 to 36% in 2009

The non-participation rate in sport increased from 66% to 75% among girls who lived in single parent families, where the parent was not employed

Children living in a couple family where both parents were not employed had a higher non-participation rate in 2006, compared with children from a one parent family where the single parent was not employed in 2009.

Age

Overall, girls were less likely to participate in organised sport than boys in all age groups. Generally, children aged 5 to 8 years had higher non-participation rates (42%) than children aged 9 to 11 years (32%) and 12 to 14 years (35%). Girls aged 9 to 11 years were more likely to participate in organised sport with a non-participation rate of 35%, than girls who were aged 5 to 8 years and 12 to 14 years (49% and 45% respectively). Boys aged 5 to 8 years were less likely to participate than boys in other age groups, with a non-participation rate of 36%.

CHILD NON-PARTICIPANTS, Organised sport - By sex and age - 2009

State or Territory of Usual Residence

Girls had higher non-participation rates in organised sport than boys in all states, however, this difference was negligible in South Australia, Tasmania and the Australia Capital Territory. Boys who lived in Tasmania had significantly higher non-participation in organised sport (40%) compared with boys living in Victoria (28%) and New South Wales (30%).

CHILD NON-PARTICIPANTS, Organised sport - By state and sex - 2009

Country of Birth

Children who were born in non main English-speaking countries had a significantly higher non-participation rate in organised sport (60%) than children who were born in Australia (36%). For girls who were born overseas, their non-participation rate was (61%) compared with girls who were born in Australia (42%).

text: From Learning, Development, and Conceptual Change. The Child's Theory of Mind. Overview. Author(s). Summary.. Wellman presents evidence that children as young as age three do possess a commonsense theory of mind—that they grasp the distinction between mental constructs and physical entities and that they have an understanding of the relationship between individuals' mental states and their overt actions. He delves in detail into questions about the nature of adults' commonsense theories of mind and about the nature of commonsense theories.. Wellman then examines the content of the three-year-old's theory of mind, the nature of children's notions of mind before age three, the changes in the theory during subsequent development from ages three to six, and the young child's conception of mind in comparison with those of older children and adults..

Lesson: Understanding the Theory of Mind

Introduction:
The theory of mind is a fundamental concept in psychology that refers to our ability to understand and predict the behavior of others. It is the capacity to attribute mental states (such as beliefs, desires, and intentions) to oneself and others, and to understand that others have beliefs, desires, and intentions that may differ from one's own. In this lesson, we will explore the development of the theory of mind in children and its implications for learning and social interactions.

Section 1: Understanding the Theory of Mind in Children

Topic 1: The Development of the Theory of Mind
Children begin to develop their theory of mind around the age of three. This means that by this age, children can understand that others have beliefs, desires, and intentions that may differ from their own. This ability is called "mentalizing," and it is essential for social interaction, communication, and learning.

Topic 2: The Content of the Theory of Mind
The theory of mind involves several components, including understanding others' beliefs, desires, and intentions; recognizing that others have beliefs, desires, and intentions that may differ from one's own; and taking into account others' perspectives when making decisions.

Topic 3: Changes in the Theory of Mind During Development
As children grow and develop, their theory of mind continues to change and become more sophisticated. For example, by the age of six, children can understand that others may have false beliefs or misunderstandings, and they can use this knowledge to predict and influence others' behavior.

Section 2: The Implications of the Theory of Mind for Learning and Social Interactions

Topic 1: Learning
The theory of mind is essential for learning because it allows us to understand and interpret the information presented to us by others. For example, if we know that someone is trying to teach us something, we can use our theory of mind to understand their intentions and beliefs and interpret their messages accurately.

Topic 2: Social Interactions
The theory of mind is also crucial for social interactions because it allows us to understand and predict the behavior of others. By attributing mental states to others, we can anticipate their reactions and respond appropriately. This ability is essential for building and maintaining relationships, resolving conflicts, and navigating social situations.

Section 3: Practical Examples and Real-World Scenarios

Topic 1: Recognizing Others' Intentions
Imagine you are playing a game with a friend. Your friend seems to be cheating, but you don't want to accuse them of something they didn't do. Using your theory of mind, you can attribute their actions to a desire to win rather than a desire to cheat. This allows you to confront your friend calmly and discuss the issue without making false accusations.

Topic 2: Resolving Conflicts
In a work setting, two colleagues have conflicting opinions on how to approach a project. By using their theory of mind, they can understand each other's perspectives and find common ground. They can acknowledge that both approaches have merit and work together to create a plan that incorporates elements from both ideas.

Conclusion:
Understanding the theory of mind is essential for learning and social interactions. By attributing mental states to ourselves and others, we can predict and influence others' behavior, resolve conflicts, and build strong relationships. As we continue to develop our theory of mind throughout childhood and adolescence, we become better equipped to navigate the complex social world around us.

Glossary:
- Theory of Mind: The capacity to attribute mental states to oneself and others and to understand that others have beliefs, desires, and intentions that may differ from one's own.
- Mentalizing: The process of attributing mental states to oneself and others.
- Commonsense theories: Everyday understandings of the world that are based on personal experience and observation.

Suffixes, Past and Polite

Verb Endings

In most languages, to express things such as tenses, the endings of verbs are often changed. But not all languages do that and not all languages have all tenses. For example, English doesn’t actually have a future tense. Verbs cannot be changed to indicate that something will happen in the future, but rather another a word or words are put before the verb to indicate future. Those words, of course, are ‘will’ and ‘be going.’

Endings don’t just indicate tense, but can indicate different nuances such as politeness.

行く

(Approximate pronunciation) ee koo (oo as in moo)

This means: Go

This is the dictionary form. This is how you have to look up a word in Japanese. This is also the casual form of the verb. When talking with friends or people younger than you, you can use this form.

行きます

(Approximate pronunciation) ee kee moss

This means: Go

The root 行く (ee koo) changes to 行き (ee key) and then the ます (moss) ending is added. This is the basically polite form and the one that you will most often use.

There are different groups of verbs and each version has it’s own forms for past tense and other tenses too.

行った (eat taw) – casual, past

行きました (ee key mawsh taw) – polite, past

For the Japanese lessons, mostly the polite form was used, as it is the most useful for getting around. It will be the one you most often hear, except in restaurants and stores where they use the honorific.

The one exception to the lesson verbs is the verb です (dess). Depending on the situation, the casual form だ (daw) was used. In surprising or emergency situations, one wouldn’t worry about politeness.

Lesson: Verb Endings and Tenses in Different Languages

Introduction:
Verb endings are an essential part of grammar in many languages. They help to convey information about tense, mood, aspect, and more. In this lesson, we will explore how verb endings work in different languages and how they can change the meaning of a sentence.

Section 1: Verb Tenses in English
English has twelve verb tenses, which can be divided into four main categories: simple, progressive, perfect, and perfect progressive. Simple tenses include the present, past, and future tenses. Progressive tenses include the present progressive, past progressive, and future progressive. Perfect tenses include the present perfect, past perfect, and future perfect. Perfect progressive tenses include the present perfect progressive, past perfect progressive, and future perfect progressive.

Questions:
- What are the four main categories of verb tenses in English?
- How many verb tenses are there in total?
- What are the simple tenses?
- What are the progressive tenses?
- What are the perfect tenses?
- What are the perfect progressive tenses?

Section 2: Verb Tenses in Japanese
In Japanese, verb endings are used to indicate tense, politeness, and other nuances. There are two main verb conjugations in Japanese: the casual form and the polite form. The casual form is used when speaking with friends or people younger than you, while the polite form is used when speaking with people older than you or in formal situations.

Questions:
- What are the two main verb conjugations in Japanese?
- What is the casual form of the verb in Japanese?
- What is the polite form of the verb in Japanese?
- How do you add the polite form to a verb in Japanese?

Section 3: Verb Tenses in Other Languages
Different languages have different ways of indicating tense using verb endings. For example, in Spanish, the subjunctive mood is used to express doubt, uncertainty, or hypothetical situations. In French, the passé composé is used to describe past events, while the imparfait is used to describe ongoing actions or repeated actions in the past.

Questions:
- What is the subjunctive mood in Spanish?
- How is it used to express doubt, uncertainty, or hypothetical situations?
- What is the passé composé in French?
- What is the imparfait in French?

Spin trapping of nitric oxide by nitronylnitroxides: measurement of the activity of no synthase from rat cerebellum.
Nitric oxide (NO) has been shown to be an important mediator in vasodilation, neurotransmission and cellular cytotoxicity. We investigated a new series of nitronylnitroxyl radicals (NNR) as spin traps for NO. It was found these radicals react with NO with rate constants of about 10(4) M-1c-1 forming stable iminonitroxides with dramatic changes in EPR spectra. To overcome fast reduction of the radicals (a few seconds in rat cerebella cytosol), NNR with charged trimethylammoniophenyl group (Ib) was incorporated into the inner volume of large unilamellar phosphatidylcholine liposomes. In this case the reduction of the radical Ib in rat cerebella cytosol is slow (ca. 1% per min). The rate of NO production by NO synthase from rat cerebellum measured by NNR, Ib, is in a reasonable agreement with that obtained by spectrophotometric method.

Lesson: Spin Trapping of Nitric Oxide by Nitronylnitroxides

### Introduction
In this lesson, we will learn about the process of spin trapping of nitric oxide by nitronylnitroxides, which is a technique used to measure the activity of nitric oxide synthase enzyme from rat cerebellum. This enzyme is responsible for producing nitric oxide, a molecule that plays an essential role in various biological processes such as vasodilation, neurotransmission, and cellular cytotoxicity.

### Section 1: Theoretical Concepts
1.1 What is Nitric Oxide?
Nitric oxide (NO) is a free radical molecule that contains one atom of nitrogen and one atom of oxygen. It is produced by the action of the enzyme nitric oxide synthase on the amino acid L-arginine.

1.2 What is Spin Trapping?
Spin trapping is a technique used to detect and study free radicals in biological systems. It involves the use of molecules called spin traps, which are capable of capturing and stabilizing free radicals.

1.3 What are Nitronylnitroxides?
Nitronylnitroxides are a class of spin traps that have the ability to react with nitric oxide (NO) to form stable iminonitroxides. These compounds have distinct electronic paramagnetic resonance (EPR) spectra that can be used to identify and quantify NO.

### Section 2: Practical Examples
2.1 Preparation of Nitronylnitroxides
To prepare nitronylnitroxides for use as spin traps, they must first be synthesized. This can be done by reacting a nitroso derivative with a suitable electrophile.

2.2 Incorporation of Nitronylnitroxides into Liposomes
To protect nitronylnitroxides from reduction by cytosolic reductants, they can be incorporated into large unilamellar phosphatidylcholine liposomes. This prevents the rapid reduction of the radicals and allows for a more accurate measurement of NO production by NO synthase from rat cerebellum.

2.3 Measurement of NO Production by NO Synthase
The rate of NO production by NO synthase from rat cerebellum can be measured by monitoring the reaction between the nitronylnitroxide and NO. This can be done using a spectrophotometer, which measures the absorbance of the reaction mixture at a specific wavelength.

### Section 3: Self-Debating Discussions
3.1 Comparison of Different Spin Traps
Compare and contrast different types of spin traps, including nitronylnitroxides, and their effectiveness in detecting and quantifying NO in biological systems.

3.2 Implications for Other Biological Processes
Consider how the use of nitronylnitroxides to study NO production could also provide insights into other biological processes that involve NO, such as neurotransmission and cellular cytotoxicity.

### Glossary
- Nitric oxide (NO): A free radical molecule containing one atom of nitrogen and one atom of oxygen, produced by the action of the enzyme nitric oxide synthase on L-arginine.
- Spin trapping: A technique used to detect and study free radicals in biological systems by using molecules called spin traps that can capture and stabilize free radicals.
- Nitronylnitroxides: A class of spin traps that can react with nitric oxide (NO) to form stable iminonitroxides, which have distinct electronic paramagnetic resonance (EPR) spectra that can be used to identify and quantify NO.
- Large unilamellar phosphatidylcholine liposomes: Vesicles composed of phosphatidylcholine and other lipids that can encapsulate nitronylnitroxides, protecting them from reduction by cytosolic reductants.
- NO synthase: An enzyme responsible for producing nitric oxide in various biological processes.

### Conclusion
In this lesson, we have learned about the process of spin trapping of nitric oxide by nitronylnitroxides and its application in measuring the activity of NO synthase from rat cerebellum. We have covered the theoretical concepts, practical examples, and self-debating discussions related to this topic. By understanding the principles behind spin trapping and nitronylnitroxides, we can gain valuable insights into the role of nitric oxide in various biological processes and apply this knowledge to new problems.

Q:

macOS App Invalid Signature

I uploaded a new binary of one of my macOS apps to iTunesConnect, but iTunes Connect is telling my that my app has an invalid signature.It worked before in El Capitan, but I just recently upgraded to Sierra, so I think that might be part of the problem. I've looked at some of the other StackOverflow questions, but none of them fix my problem. iTunes Connect sent me an email telling me about the problem, but I don't know how to fix it. Here's what the email said:

Invalid Signature - This error occurs when you have signed your app's installer incorrectly. There are two certs required for this process: the "3rd Party Mac Developer Application" cert and the "3rd Party Mac Developer Installer" cert. When signing your package, you need to ensure that you are using the Installer cert to sign your package. Ensure that you are specifying this cert when submitting your app via the Xcode Organizer or when running productbuild from the command line.

How can I fix this?
EDIT: The more I look around in Xcode trying to figure out what the problem might be, the more I'm confused. In Keychains, I have the correct certificates (I've even got several duplicates of the same certificate) but iTunes Connect is still telling me Invalid Signature. I'm not sure what's wrong.
I really want to get this problem fixed, so if more information is needed about the problem I'll be happy to provide more.

A:

After a lot of experimenting and some ideas from my friend Thomas (thanks @TDM!) I finally figured out the solution! Here's what I did:
So first I went under Xcode > Preferences > Accounts > Selected my account > View Details and under Signing Identities I made sure to create the 2 certificates that I needed. After I did that I thought I was done, but Apple rejected my app again and I got the same error.
In Keychains I noticed that I had 4 "3rd Party Mac Developer Application" certificates and 4 "3rd Party Mac Developer Installer" certificates. My friend Thomas suggested I delete the duplicates. I had thought of that too. But I had those certificates there a while and they hadn't caused me any trouble, or at least not until I upgraded to macOS Sierra. But, I decided to try.
I deleted the 6 older certificates (3 of the "3rd Party Mac Developer Application" certificates and 3 of the "3rd Party Mac Developer Installer" certificates) but kept the 2 two certificates that I had just recently created. I uploaded the project once again to iTunes Connect and this time it worked!

5. Press return to begin the build process.
6. Once the build is complete, you will see a message indicating that the build succeeded.
7. Next, run `productsign` and enter your login password when prompted.
8. Enter the name of your app followed by the word "sign" (e.g., MyAppSign).
9. Press return to begin the signing process.

Section 3: Verifying the Signature

After you have created a valid signature for your macOS app, you need to verify that it is working correctly. To do this, follow these steps:

1. Open Terminal and navigate to your project directory.
2. Run `codesign` and enter the name of your app (e.g., MyApp).
3. If the signature is valid, you will see a message indicating that the app is signed and that the signature is valid.

Section 4: Troubleshooting

If you encounter any issues while creating a valid signature for your macOS app, try the following troubleshooting steps:

1. Ensure that you are using the correct certificates in Xcode.
2. Check that you have the latest version of Xcode installed.
3. Verify that you have selected the correct scheme for your app.

Lesson: Introduction to Statistics

## Section 1: What is Statistics?
Statistics is the branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of data. It helps us make sense of the world by providing insights into the behavior of people, events, and objects.

## Section 2: Types of Studies
There are different types of studies that can be used to answer research questions. These include:

1. Observational study: This type of study involves observing people or events without trying to change them. It can be used to describe patterns or relationships in the data.

2. Experimental study: This type of study involves manipulating one or more variables to see how they affect the outcome. It can be used to test hypotheses and determine cause-and-effect relationships.

3. Quasi-experimental study: This type of study involves comparing two groups that are similar in many ways but differ in one important aspect. It can be used to estimate the effect of the variable being manipulated.

4. Non-experimental study: This type of study does not involve manipulating any variables. It can be used to describe patterns or relationships in the data.

## Section 3: Variables and Data Types
Variables are the building blocks of statistics. They can be classified into two types:

1. Qualitative variables: These are variables that can be observed but cannot be measured. Examples include gender, eye color, and political affiliation.

2. Quantitative variables: These are variables that can be measured and counted. Examples include age, weight, and height.

Data types can also be classified into two types:

1. Discrete data: These are data points that can only take on specific values. Examples include the number of students in a class or the number of legs on a table.

2. Continuous data: These are data points that can take on any value within a range. Examples include temperature, weight, and time.

## Section 4: Applying Statistics to Real-World Problems
Statistics can be applied to a wide range of problems in various fields, including business, medicine, and social sciences. For example, a pharmaceutical company may use statistical methods to compare the efficacy of different drugs in treating a disease. A doctor may use statistical methods to determine whether a new treatment is more effective than an existing one. A social scientist may use statistical methods to study the relationship between income and happiness.

## Conclusion
In conclusion, statistics is a powerful tool that can help us make sense of the world around us. By understanding the different types of studies, variables, and data types, we can apply statistical methods to a wide range of problems and gain valuable insights into the behavior of people, events, and objects.

I have an abundance of 1/4, 3ply, ACX, very good stock, no voids, no errors on A side. I'm planning to laminate the plywood in a jig, ultimately getting the lamination thickness to somewhere around 1.5-2". My question is, can I use a good polyurethane glue for glue up and then sheath the entire arch in FG cloth and epoxy resin? Since it won't come in contact with too much water, I think it should hold up.
