Summary:Health Education

SOS Children's Villages provides medical care free of charge by skilled staff in SOS Medical Centers all over the world. In many cases, the conditions and diseases that are treated could have been prevented by expert advice and simple preventive measures.

By working closely together with local authorities, communities and other NGOs, SOS Children’s Villages strives to spread basic knowledge and offer expertise on the prevention and treatment of diseases and conditions often closely related to poverty.

Malnutrition

Worldwide, around 20 million children under five are severely malnourished and are therefore particularly at risk of dying in childhood. In many cases, the root of the problem is not the lack of food, but a lack of knowledge about balanced, age-appropriate diets. Through community centers and social centers around the world, SOS Children’s Villages builds awareness about the causes and consequences of malnutrition, offers prevention methods that are within easy reach of families, and develop nutrition programmes based on food staples that are readily available in the region.

HIV/AIDS

Over 14 million children worldwide have lost one or both of their parents to AIDS. The spread of the disease and its impact on those already infected is often made worse by the fact that the subject is taboo, particularly in those regions where it is spreading most rapidly. SOS Children’s Villages providing age-appropriate information to children, young people and adults, both promoting behaviour that prevents infection as well as destigmatising those already infected. This also means that more parents with HIV are willing to accept their situation and undergo treatment so they can keep providing a stable home for their children.

Maternal and perinatal health

Half a million mothers die every year of causes related to pregnancy; the mortality rate of children is at its highest during the first five months after birth. Educating women and girls on perinatal health, i.e. the time three months before, during and one year following childbirth, is widely recognized as central to minimizing infant and maternal mortality. In SOS Medical Centers, mothers receive perinatal health care from skilled staff, while information and care are offered to families and communities through community centres and social centres around the world.

Introduction:

Health education is an essential part of our lives. It helps us understand the importance of taking care of our bodies, minds, and spirits. In this lesson, we will learn about some of the most common health issues that people face today and how we can prevent them. We will also discuss the role of SOS Children's Villages in providing health education to children and families in need.

Section 1: Malnutrition

Malnutrition is a serious problem that affects millions of children worldwide. It occurs when a child does not receive enough nutrients to grow and develop properly. Malnutrition can lead to many health problems, including stunted growth, weakened immune systems, and even death.

Prevention:

There are several things that parents and caregivers can do to prevent malnutrition in children. These include:

- Feeding children a balanced diet that includes plenty of fruits, vegetables, whole grains, and lean protein sources.
- Ensuring that children get enough exercise and physical activity.
- Providing clean water and proper sanitation to prevent waterborne illnesses.
- Getting children vaccinated against preventable diseases.

Section 2: HIV/AIDS

HIV/AIDS is a serious disease that can be transmitted through contact with infected blood or other bodily fluids. It is caused by the human immunodeficiency virus (HIV), which attacks the body's immune system and makes it difficult for the body to fight off other infections and diseases.

Prevention:

There are several ways to prevent HIV/AIDS. These include:

- Practicing safe sex by using condoms and getting tested for sexually transmitted infections regularly.
- Avoiding sharing needles or other drug paraphernalia.
- Getting vaccinated against hepatitis B, which can reduce the risk of HIV transmission.

Lesson: Introduction to Audio Equipment

## Section 1: Theoretical Concepts
In this section, we will learn about the basic principles of audio equipment and their role in producing high-quality sound.

**Topic 1: Types of Audio Equipment**
There are several types of audio equipment that are used in the music industry, including microphones, headphones, speakers, and mixers. Each type of equipment serves a specific purpose in the recording and production process.

**Topic 2: Frequency Response**
Frequency response is a measure of how well an audio system reproduces different frequencies of sound. A flat frequency response means that the system accurately reproduces all frequencies without any boost or cut in volume.

**Topic 3: Signal-to-Noise Ratio (SNR)**
The signal-to-noise ratio is a measure of the level of unwanted background noise compared to the desired signal. A higher SNR means that the audio equipment is less likely to produce unwanted noise, resulting in a cleaner and clearer sound.

## Section 2: Practical Examples
In this section, we will apply the theoretical concepts we learned in the previous section to real-world scenarios.

**Example 1: Recording Vocals**
When recording vocals, a high-quality microphone with a flat frequency response and a high signal-to-noise ratio is essential for capturing the true tone of the singer's voice.

**Example 2: Mixing Music**
When mixing music, a professional-grade mixer with a wide range of equalization options and a high SNR is necessary to create a balanced and polished final product.

**Example 3: Listening to Music**
When listening to music, high-quality headphones or speakers with a flat frequency response and a high SNR are crucial for accurately reproducing the intended sound of the recording.

## Section 3: Self-Debating Discussions
In this section, we will engage in self-debating discussions to develop our critical thinking skills.

**Discussion Topic 1: Is it worth investing in high-end audio equipment?**
Some people argue that high-end audio equipment is necessary for achieving the best possible sound quality, while others believe that the difference in sound quality between high-end and budget equipment is negligible for most listeners. What are your thoughts on this topic?

**Discussion Topic 2: How important is the design of audio equipment?**
While some people prioritize the sound quality of audio equipment above all else, others believe that the design and aesthetic appeal of the equipment is equally important. Do you think that the design of audio equipment plays a significant role in the overall listening experience? Why or why not?

## Glossary
- Frequency response: A measure of how well an audio system reproduces different frequencies of sound.
- Signal-to-noise ratio (SNR): A measure of the level of unwanted background noise compared to the desired signal.

Lesson: Introduction to Algebra

### Section 1: Theoretical Concepts

Algebra is a branch of mathematics that deals with the manipulation of symbols and the study of relationships between variables. It is used to solve problems involving quantities, such as the number of items in a set or the amount of money in a bank account.

**Question:** What is algebra used for?
**Answer:** Algebra is used to solve problems involving quantities, such as the number of items in a set or the amount of money in a bank account.

### Section 2: Practical Examples

Let's consider an example problem: If you have 2 apples and your friend gives you 3 more, how many apples do you have in total?

Using algebra, we can represent this situation with the variable "x" representing the number of apples:

2 + x = total number of apples

Solving for "x", we get:

x = total number of apples - 2

So, if you have 2 apples and your friend gives you 3 more, you will have a total of 5 apples.

**Question:** How does algebra help us solve practical problems like this one?
**Answer:** Algebra helps us represent and solve problems involving quantities by using variables to represent unknown values and mathematical operations to manipulate those values.

### Section 3: Real-World Scenarios

Now let's consider another example problem: If a box contains 10 candies and you eat 4 of them, how many candies are left in the box?

Using algebra, we can represent this situation with the variable "x" representing the number of candies eaten:

10 - x = remaining candies in the box

Solving for "x", we get:

x = remaining candies in the box - 10

So, if you eat 4 candies out of a box containing 10, there will be 6 candies left in the box.

**Question:** How can we use algebra to solve real-world problems like this one?
**Answer:** We can use algebra to represent and solve problems involving quantities by using variables to represent unknown values and mathematical operations to manipulate those values. This allows us to solve problems involving changes in quantity over time, such as how many candies are left after some have been eaten.

### Glossary
- Variable: A letter or symbol representing a value that can change based on different conditions or situations.
- Manipulation: The act of changing or adjusting something in order to achieve a desired result.
- Quantity: A measurable amount of something, such as the number of items in a set or the amount of money in a bank account.
- Represent: To show or depict something using symbols or other forms of communication.
- Solve: To find the answer or solution to a problem.
- Operation: A mathematical process or action that involves combining numbers or other values in a specific way.
- Equation: A mathematical statement that uses symbols and operations to represent the relationship between two or more variables.

### Conclusion
In this lesson, we learned about the basics of algebra, including its practical applications in solving problems involving quantities. We also explored real-world scenarios where algebra can be used to solve problems involving changes in quantity over time. By understanding the concepts and techniques introduced in this lesson, students can develop the skills necessary to apply algebra to new and complex problems.

Lesson: Introduction to Native Bees

## Section 1: What are Native Bees?
Native bees are a group of bees that are naturally found in North America. They are different from honey bees, which are not native to the continent. Native bees play an essential role in pollination and are responsible for the reproduction of many plants.

## Section 2: Why are Native Bees Important?
Native bees are crucial for the health of our ecosystem. They are responsible for pollinating many plants, including fruits, vegetables, and nuts. Without them, our food supply would be at risk. Additionally, native bees are an essential part of the food chain, as they provide food for other animals such as birds and bats.

## Section 3: How can we Help Native Bees?
There are several ways we can help native bees. One way is to provide them with a safe place to live by planting flowers that provide nectar and pollen. Another way is to avoid using pesticides, as they can harm native bees. Finally, we can spread awareness about the importance of native bees and encourage others to take action to protect them.

## Glossary:
- Native bee: A bee that is naturally found in North America
- Pollination: The process by which pollen is transferred from the male part of a flower to the female part, enabling fertilization and the production of seeds
- Food chain: The sequence of organisms that eat or are eaten by others in a particular ecosystem

## Conclusion:
Native bees are an essential part of our ecosystem, and they need our help. By planting flowers, avoiding pesticides, and spreading awareness, we can ensure that native bees continue to thrive and play their vital role in pollination.


text: .. Over the next two weeks, the phone-hacking scandal exploded. The younger Murdoch's big play: taking over 100 percent ownership of British satellite broadcaster BSkyB was halted. He is no longer the heir apparent to take over running the Murdoch empire when his 80 year old father, Rupert, decides to step aside.. This has been a bad week for the Murdochs here. They launched the Sun on Sunday to replace the News of the World which they closed last summer. Almost immediately the focus of the Leveson Enquiry into the scandal shifted to The Sun and more dark revelations and accusations have been made.. Yesterday, Jacqui Hames, a former detective and host of a BBC true-life crime show, alleged the News of the World had intimidated her and her then husband, also a detective, and had interfered with a murder investigation he was involved in.. If the allegation is true than it may provide even more ammunition for the FBI to bring charges against News Corp in America under the Foreign Corrupt Practices Act.

Q:

Current in a circuit with diodes

These are two examples from the book. Why in the first one it's neglecting \$i_{2}\$ ,shouldn't the diode's current be found with Kirchhoff's first law like in the second example? How can I know when to consider the second current and when not? I know that the diode's current get's very large for forward voltage but why the current isn't neglected in every parallel circuit like in these two.

A:

Why in the first one it's neglecting \$i_2\$?

Because if you take \$V_i\$ as an independent variable, \$i_2\$ doesn't change \$V_o\$. \$V_o\$ depends only on \$V_i\$, R, and R1.

How can I know when to consider the second current and when not?

You can calculate what the second current is (\$V_i / R_2\$ in this case) and then see whether you ever use that information in calculating whatever final result you're going for (\$V_o\$ in this case).

why the current isn't neglected in every parallel circuit like in these two.

Because sometimes it matters. If the source providing \$V_i\$ had an internal resistance, for example, then \$i_2\$ would contribute to the drop across that internal resistance, so you'd have to know it to find the output voltage.

Lesson: Understanding Circuits with Diodes

Introduction:

Diodes are electronic components that allow current to flow in one direction but not in the other. They are commonly used in circuits to regulate voltage, protect sensitive components, and convert alternating current to direct current. In this lesson, we will learn about circuits with diodes and how they work.

Core Value:

The core value of this lesson is to understand how diodes behave in circuits and how they can be used to control the flow of electricity.

Section 1: Basic Concepts

Topic 1: What is a Diode?

A diode is an electronic component that allows current to flow in one direction but not in the other. It is made up of a semiconductor material, usually silicon or germanium, that has a p-n junction. When a voltage is applied across the diode, electrons move from the n-type material to the p-type material, creating a flow of current.

Topic 2: Types of Diodes

There are several types of diodes, including:

1. PN junction diodes: These are the most common type of diode and are made up of a p-type and an n-type semiconductor material joined together.
2. Zener diodes: These diodes have a breakdown voltage, which means they allow current to flow in the reverse direction when a certain voltage is applied.
3. Schottky diodes: These diodes are made of metal-semiconductor materials and have a lower forward voltage drop than PN junction diodes.

Section 2: Circuits with Diodes

Topic 1: Voltage Regulator Circuit

A voltage regulator circuit is used to maintain a constant voltage across a load. It uses a diode to drop the voltage across the load, allowing a constant current to flow. The formula for calculating the voltage drop across the diode is:

V_drop = I * R

where V_drop is the voltage drop across the diode, I is the current flowing through the diode, and R is the resistance of the diode.

Topic 2: Rectifier Circuit

A rectifier circuit is used to convert alternating current (AC) to direct current (DC). It uses a diode to allow current to flow in one direction only, effectively blocking current from flowing in the opposite direction. The formula for calculating the output voltage of a rectifier circuit is:

V_out = V_in * sin(ωt)

where V_out is the output voltage, V_in is the input voltage, ω is the angular frequency of the AC source, and t is time.

Section 3: Practical Examples

Example 1: A flashlight circuit uses a diode to convert DC power from a battery into AC power to light an LED. The formula for calculating the current flowing through the LED is:

I_LED = V_in / R_LED

where I_LED is the current flowing through the LED, V_in is the voltage across the LED, and R_LED is the resistance of the LED.

Example 2: A radio circuit uses a diode to convert the AC signal from the antenna into a DC signal that can be amplified by the receiver. The formula for calculating the voltage across the diode is:

V_diode = R_L / (1/ω_L - 1/ω_C)

where V_diode is the voltage across the diode, R_L is the inductor resistance, ω_L is the angular frequency of the inductor, and ω_C is the angular frequency of the capacitor.

Conclusion:

In this lesson, we learned about diodes, their basic concepts, and how they can be used in circuits. We also explored practical examples of circuits with diodes and how they work. By understanding these concepts, we can apply them to new problems and create more complex circuits.


text: This practice note shares the experience of REDRESS and Trauma Treatment International (TTI) and is intended to assist clinicians, such as physicians and clinical psychologists, to undertake an assessment and elaborate reports that are compliant with the United Nations Manual on the Effective Investigation and Documentation of Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (Istanbul Protocol). REDRESS and TTI would like to thank the United Nations Voluntary Fund for Victims of Torture and the Matrix Causes Fund for their generous support of this project..

textbook:
Lesson 1: Introduction to the Istanbul Protocol

### Section 1: Theory
The Istanbul Protocol is a set of guidelines developed by the United Nations that provides instructions on how to investigate and document cases of torture and other forms of cruel, inhuman, or degrading treatment or punishment. It is designed to help clinicians, such as physicians and clinical psychologists, to undertake an assessment and elaborate reports that are compliant with the protocol.

### Section 2: Practice
To apply the Istanbul Protocol, clinicians must follow these steps:

1. Obtain informed consent from the patient before conducting any examination or interview.
2. Conduct a thorough medical examination, including a review of the patient's medical history and a physical examination.
3. Use standardized procedures and instruments to document the findings.
4. Interview the patient about their experiences, including any allegations of torture or other forms of ill-treatment.
5. Analyze the findings and draw conclusions about whether the patient's injuries or symptoms are consistent with torture or other forms of ill-treatment.
6. Compile a comprehensive report that includes the patient's medical history, physical examination findings, photographs of injuries, and a detailed description of the alleged torture or other forms of ill-treatment.
7. Submit the report to the appropriate authorities for further investigation and prosecution.

### Section 3: Practical Examples
Let's consider an example of a patient who alleges that they were tortured while in custody. The clinician would follow the steps outlined above to document the patient's injuries and gather information about the alleged torture. For instance, the clinician may ask the patient questions such as:

- What types of physical or mental abuse did you experience while in custody?
- Were you beaten, electrocuted, or subjected to any other form of physical violence?
- Were you deprived of food, water, or sleep?
- Were you threatened or intimidated in any way?

By analyzing the patient's responses and medical findings, the clinician can determine whether the injuries or symptoms are consistent with torture or other forms of ill-treatment.

### Glossary
- Istanbul Protocol: A set of guidelines developed by the United Nations that provides instructions on how to investigate and document cases of torture and other forms of cruel, inhuman, or degrading treatment or punishment.
- Torture: Any act by which severe pain or suffering, whether physical or mental, is intentionally inflicted on a person for such purposes as obtaining from him or her or a third person information or a confession, punishing him or her for an act he or she or a third person has committed or is suspected of having committed, or for any reason based on discrimination of any kind, when such pain or suffering is inflicted by or at the instigation of or with the consent or acquiescence of a public official or other person acting in an official capacity. It does not include pain or suffering arising only from, inherent in, or incidental to lawful sanctions.
- Ill-treatment: The expression "ill-treatment" includes cruel, inhuman or degrading treatment or punishment, whether or not it amounts to torture as defined in the preceding paragraph.

### Conclusion
Understanding the Istanbul Protocol is crucial for clinicians who work with patients who have experienced torture or other forms of ill-treatment. By following the guidelines outlined in the protocol, clinicians can document cases of torture and other forms of cruel, inhuman, or degrading treatment or punishment accurately and effectively. This knowledge can be applied to new cases, helping to prevent future instances of torture and other forms of ill-treatment.

Washington (AFP) - The US Congress voted Thursday to raise the minimum age to buy tobacco and e-cigarettes from 18 to 21 across the country, a move intended to stem the rising tide of youth vaping.

Passed by the Senate as part of a wider budgetary bill, it will take effect next year and will mean that tobacco and e-cigarettes will join alcohol as substances that are prohibited to purchase for those under the age of 21.

Nineteen of the country's 50 states and the capital Washington, DC had already set 21 as the minimum age.

"I'm proud the Senate approved legislation today including our Tobacco-Free Youth Act to help address this urgent crisis and keep these dangerous products away from our children," said Senate Majority Leader Mitch McConnell, a Republican, who co-sponsored the bill along with Democratic Senator Tim Kaine.

The bill is aimed at combating the skyrocketing popularity of vaping among young people, who have turned away from traditional cigarettes and even alcohol in favor of e-cigarettes.

About 28 percent of high school seniors reported vaping in the last 30 days according to a government survey for the year 2019, compared to just 11 percent in 2016.

Another benchmark survey published on Wednesday, called Monitoring the Future, showed that 52 percent of high school students said they had consumed alcohol over the last year, against 73 percent in 2000.

For cigarettes, the proportion of high school students who smoked in the last month fell to under six percent, almost half the figure in 2016.

- Patchy enforcement -

This summer also saw a major health crisis tied to vaping: an acute lung illness epidemic that has killed more than 50 mostly young people and sickened more than 2,500.

The illness was later tied a substance called vitamin E acetate, which is used as a thickening agent for vaping products containing the main psychoactive substance of cannabis -- called THC -- that is often sold on the black market.

But the measure stopped far short of a move announced by President Donald Trump earlier this year, only to be quietly shelved: a ban on flavored vapor such as fruit and menthol, news of which was met with a fierce backlash by industry groups.

Story continues

Market leader Juul has since withdrawn non-tobacco flavors from the US market.

But some anti-vaping groups said the new law did not go far enough to address the issue.

"Simply raising the age is insufficient to stem the ongoing epidemic of adolescent nicotine addiction wrought by the deliberate abuses of the vaping industry," said Rob Crane of Preventing Tobacco Addiction Foundation.

The federal government as already supposed to be enforcing the current minimum age of 18, but "their negligence in requiring retailer compliance is one of the reasons that 5.2 million American middle school and high school students are inhaling high-potency nicotine regularly," he added.

Lesson: Understanding the Rising Tide of Youth Vaping

Introduction:
Vaping has become increasingly popular among young people in recent years. This trend has raised concerns among parents, educators, and health professionals due to the potential negative effects of vaping on health. In this lesson, we will explore the reasons behind the rising tide of youth vaping, the dangers associated with it, and what can be done to address this issue.

Section 1: Understanding the Popularity of Vaping Among Young People

Question: Why do young people prefer vaping to traditional cigarettes?
Answer: There are several reasons why young people prefer vaping to traditional cigarettes. Firstly, vaping devices are often seen as more discreet than cigarettes, making them easier to use in public places without attracting attention. Secondly, vaping devices come in a wide range of flavors, which appeal to younger users who may not be attracted to the taste of tobacco. Finally, many young people believe that vaping is less harmful than smoking, despite evidence to the contrary.

Section 2: The Dangers of Vaping

Question: What are the potential negative effects of vaping on health?
Answer: While vaping may be less harmful than smoking, it is not without its risks. The liquid used in vaping devices often contains nicotine, which is highly addictive and can harm brain development in adolescents. Additionally, vaping devices can expose users to other toxic chemicals, such as formaldehyde and benzene, which can increase the risk of lung disease and cancer. Finally, research suggests that vaping may actually prime the brain for addiction to other drugs, making it more difficult for young people to resist the temptation to try other substances.

Section 3: Addressing the Rising Tide of Youth Vaping

Question: What can be done to address the rising tide of youth vaping?
Answer: There are several steps that can be taken to address the rising tide of youth vaping. Firstly, educating young people about the potential dangers of vaping is essential. This can be done through school-based programs, public service announcements, and parental guidance. Secondly, restricting access to vaping devices and e-cigarettes can help reduce their appeal. Many states and cities have already raised the minimum age for purchasing these products to 21, and this trend is likely to continue. Finally, addressing the underlying social and emotional factors that contribute to young people's use of vaping devices is also important. This may involve providing support for mental health and well-being, as well as creating opportunities for positive social interaction.

Conclusion:
In conclusion, the rising tide of youth vaping is a complex issue that requires a multi-faceted approach. By educating young people about the potential dangers of vaping, restricting access to vaping devices, and addressing the underlying social and emotional factors that contribute to their use, we can help reduce the appeal of vaping and protect the health and well-being of our young people.

Is intravenous cholangiography still useful?
A retrospective study was performed to determine the usefulness of the intravenous cholangiogram for evaluation of common bile duct disease. Using interpretations obtained by chart review, 128 intravenous cholangiograms were categorized according to common bile duct visualization. Fifty-five percent of the studies were considered technically adequate for interpretation, while 23% and 22% were suboptimal and nondiagnostic, respectively. The intravenous cholangiogram diagnoses were verified when possible by comparison with the findings of: (a) endoscopic retrograde cholangiography, (b) operative cholangiography, (c) choledochotomy, or (d) autopsy. In verified studies of adequate intravenous cholangiograms, the diagnostic error rate was 40%, largely owing to missed stones. We conclude that the intravenous cholangiogram is usually unreliable for biliary tract evaluation, and should be replaced by alternative studies such as endoscopic or transhepatic cholangiography.

Lesson: Introduction to Medical Imaging

## Chapter 1: Overview of Medical Imaging

Medical imaging is the process of creating images of the human body for clinical purposes. These images are used to diagnose, treat, and monitor diseases and injuries. There are several types of medical imaging, including X-rays, ultrasounds, computed tomography (CT) scans, magnetic resonance imaging (MRI), and positron emission tomography (PET).

In this lesson, we will focus on one type of medical imaging: intravenous cholangiography. This technique involves injecting a dye into a patient's veins and then taking X-ray pictures of the liver and gallbladder to check for blockages or other problems.

## Chapter 2: How Intravenous Cholangiography Works

Intravenous cholangiography works by using a special dye that shows up on X-ray pictures. The dye is injected into a patient's vein, and it travels through the liver and gallbladder. As the dye moves through these organs, it highlights any blockages or other problems.

The X-ray machine takes pictures of the liver and gallbladder while the dye is being injected. These pictures show the shape and structure of the organs, as well as any problems that may be present.

## Chapter 3: Advantages and Disadvantages of Intravenous Cholangiography

There are several advantages to using intravenous cholangiography. It is a non-invasive procedure, meaning that it does not require surgery. It is also relatively quick and easy to perform, and it can provide valuable information about the structure and function of the liver and gallbladder.

However, there are also some disadvantages to this technique. One major issue is that it is not always accurate. In some cases, the dye may not show up on the X-ray pictures, making it difficult to diagnose problems. Additionally, intravenous cholangiography can be expensive and time-consuming, and it may not be covered by insurance in all cases.

## Chapter 4: Alternatives to Intravenous Cholangiography

There are several alternatives to intravenous cholangiography that can be used to diagnose problems with the liver and gallbladder. One popular option is endoscopic retrograde cholangiopancreatography (ERCP), which involves inserting a tube with a camera on the end into the mouth and down into the digestive tract. Another option is magnetic resonance cholangiopancreatography (MRCP), which uses magnetic fields and radio waves to create detailed images of the liver and gallbladder.

## Chapter 5: Conclusion

In conclusion, intravenous cholangiography is a useful tool for diagnosing problems with the liver and gallbladder. However, there are limitations to this technique, and it may not always be the best option for diagnosis. Alternatives like ERCP and MRCP offer additional options for diagnosing and treating these conditions. By understanding the strengths and weaknesses of each imaging technique, doctors can make informed decisions about the best course of action for their patients.

Facilitation of experimental allergic encephalomyelitis by irradiation and virus infection: role of inflammatory cells.
Infection with an avirulent strain of Semliki Forest virus (SFV-A7) facilitates the development of experimental allergic encephalomyelitis (EAE) in a genetically resistant BALB/c mouse strain. Irradiation which is necessary for EAE induction caused a decrease in the total number of lymphocytes and an increase in CD4+/CD8+ T cell ratio in the spleen of BALB/c mice. EAE induction increased the ratio further until clinical and histological signs of EAE appeared. Entry of perivascular CD4+ and CD8+ cells preceded the onset of clinical signs and the appearance of MAC-1+ cells in the central nervous system (CNS). In the acute phase of EAE, cellular infiltrates, which were sparse, consisted mainly of MAC-1+ cells and a few CD4+ and CD8+ cells. Inflammatory cells gradually disappeared during the recovery phase. SFV-A7 infection after irradiation and EAE induction did not significantly change the CD4+/CD8+ ratio in the spleen or in the CNS infiltrates but enhanced the entry of inflammatory cell into the CNS. Similar perivascular cell influx was also seen in untreated mice infected with SFV-A7. We conclude that observed rapid reduction of splenic mononuclear cells and increase of the CD4+/CD8+ T cell ratio caused by irradiation prior EAE induction are early crucial events in disease induction in this resistant strain of mice. SFV-A7 infection, which further facilitates the development of EAE, does not induce immunoregulatory changes but provides its effect by enhancing the entry of inflammatory cells into the CNS. The combination of these two mechanisms thus effectively breaks the natural resistance against EAE in this genetically resistant mouse strain.

Lesson: Introduction to Immunology

### Section 1: What is Immunology?
Immunology is the study of the immune system, which is the body's defense against infections and diseases. The immune system is made up of cells, tissues, and organs that work together to protect the body from germs and other foreign substances.

### Section 2: How does the Immune System Work?
The immune system works by recognizing foreign substances, such as bacteria, viruses, and parasites, and then attacking them. This is done through a complex process involving various types of cells, including white blood cells, which are also known as leukocytes. There are two main types of white blood cells: phagocytes, which engulf and destroy foreign substances, and lymphocytes, which produce antibodies to neutralize pathogens.

### Section 3: The Role of Inflammatory Cells in the Immune Response
Inflammatory cells play a crucial role in the immune response. They are responsible for detecting and responding to foreign substances in the body. Inflammatory cells include macrophages, neutrophils, and lymphocytes. Macrophages are responsible for engulfing and digesting pathogens, while neutrophils are responsible for releasing enzymes that break down bacteria. Lymphocytes, on the other hand, are responsible for producing antibodies and coordinating the immune response.

### Section 4: The Importance of the Immune System
The immune system is essential for maintaining good health and preventing illness. It helps protect the body from infections, such as the common cold and the flu, as well as more serious diseases, such as cancer and HIV. A strong immune system is also important for preventing autoimmune diseases, where the immune system mistakenly attacks the body's own cells.

### Section 5: Conclusion
Understanding the immune system is important for maintaining good health and preventing illness. By studying immunology, we can learn more about how the immune system works and how to keep it functioning properly. This knowledge can help us develop new treatments for diseases and improve our overall health and well-being.

1. Field of the Invention
The present invention relates to a sensor and, particularly, to a temperature sensor preferably used for sensing the temperature of an evaporator.
Moreover, the present invention relates to a sensor adapted to be formed by fixing a cylindrical metal case for accommodating a sensing element on a three-dimensional substrate and, particularly, to a temperature sensor adapted to be formed by installing an installation portion for mounting on an evaporator and a cylindrical metal case for accommodating a temperature sensing element on a three-dimensional substrate in a vertically standing state.
2. Description of the Related Art
In an air-conditioner for a vehicle, a temperature sensor is installed on an evaporator in order to measure the temperature of a refrigerant. The construction of the temperature sensor for an evaporator is explained with reference to FIGS. 12A to 12D. FIG. 12A is a plan view of an evaporator temperature sensing element 110, FIG. 12B is an elevation view from the arrow X12b in FIG. 12A, FIG. 12C is an elevation view from the arrow X12c in FIG. 12A, and FIG. 12D is a sectional view taken along the line X12d-X12d in FIG. 12C.
The evaporator temperature sensor 110 is formed as an insert molding with a resin, wherein an aluminum case 130 for accommodating a temperature sensing element 32 at the top end thereof and an installation portion 126 for mounting on an evaporator are installed on a substantially cubic substrate 120 in a standing state. Grooves 126a for preventing withdrawal are formed on the installation portion 126. A harness 40 connected to a signal wire 42 from the temperature sensing element passes through a vertical wall 120c of the substrate 120. The evaporator temperature sensor 110 is fabricated by accommodating the temperature sensing element 32 in the aluminum case 130, by placing the aluminum case 130 filled with filler 122 in a mold and by insert molding with a resin.
FIG. 13 shows a state in which the evaporator temperature sensor 110 is installed on an evaporator 50.
The evaporator temperature sensor 110 is installed by inserting the aluminum case 130 and the installation portion 126 into spaces between fins 52 of the evaporator 50.
In the patent documents 1 to 4, air-conditioners for a vehicle using an evaporator temperature sensor are disclosed.
[Patent Document 1]                Japanese Unexamined Patent Publication (Kokai) No. 2002-211,233
[Patent Document 2]                Japanese Unexamined Patent Publication (Kokai) No. 7-237,440
[Patent Document 3]                Japanese Unexamined Patent Publication (Kokai) No. 6-48,168
[Patent Document 4]                Japanese Unexamined Patent Publication (Kokai) No. 5-238,253
In the evaporator temperature sensors 110 of a prior art, however, as the harness 40 is not fixed to the substrate 120, the root portion of the harness 40 at which the harness 40 comes out from the substrate 120 is likely to be bent and is often broken and disconnected due to vibration during operation of a vehicle or the vibration of a compressor of an air-conditioner.
During the insert molding with a resin, however, as heat is exerted at around 250° C., the harness 40 is required to be made of a material having heat resistance higher than or equal to 250° C., and thereby, the cost of the evaporator temperature sensor is increased.
The evaporator temperature sensor may be installed on various positions in accordance with the type of a vehicle or air-conditioner casings. Due to this installation position, the harness is required to be long which makes it difficult to handle. In this configuration, during insert molding, if the harness is long, it is troublesome to set the harness into a mold and easy to insert the harness into the mold. On the other hand, in order to correspond to various installation positions, a plurality of harnesses having various lengths should be prepared, but it is difficult to combine these harnesses having various lengths together by insert molding. Therefore, the manufacturing process is difficult to automatically perform and is, instead, manually performed with resulting increase in the manufacturing cost.
On the other hand, if the harness 40 is not fixed to the substrate 120 by insert molding, the root portion of the harness 40 at which the harness 40 comes out from the substrate 120 is likely to be bent and may be broken and disconnected due to vibration during operation of a vehicle or the vibration of a compressor of an air-conditioner.
In addition, if the relative position of the harness 40 with respect to the evaporator temperature sensor 110 is not fixed, when the evaporator temperature sensor 110 is installed on the air-conditioner case, the bend of the harness 40 must be adjusted. Due to this, there is a problem in which it is difficult to automate the installation of the evaporator temperature sensor 110. The operation of installation is explained with reference to FIG. 13.
After the evaporator temperature sensor 110 is installed on the evaporator 50 accommodated in an air-conditioner case 60, the harness 40 is settled into a groove 64, lids 62A and 62B are closed and, thereby, the installation operation is finished. During the operation, if the position of the harness 40 is not fixed, the efficiency of the operation is lowered. Moreover, if the position of the harness 40 is not fixed, automatic assembling is difficult.

Lesson: Introduction to the Three Laws of Robotics

#### Section 1: Theoretical Concepts
The Three Laws of Robotics are a set of guidelines created by science-fiction writer Isaac Asimov in his 1942 short story 'Runaround.' These laws serve as engineering safeguards and built-in ethical principles for robots. The laws are:

1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.
2. A robot must obey orders given to it by human beings except where such orders would conflict with the First Law.
3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.

#### Section 2: Practical Examples
These laws have been used in dozens of stories and novels by Asimov. Real-life roboticists are also considering these laws as their creations become more autonomous. For example, autonomous vehicles need to follow traffic rules and prioritize the safety of their occupants while avoiding accidents.

#### Section 3: Self-Debating Discussions
One of the challenges of autonomous vehicles is determining how they should behave in a crisis. What if a vehicle's efforts to save its own passengers by, say, slamming on the brakes risked a pile-up with the vehicles behind it? Or what if an autonomous car swerved to avoid a child, but risked hitting someone else nearby? These are complex decisions that require careful consideration of the consequences.

#### Glossary
- Robotics: The study of robots and their design, construction, and operation.
- Autonomous vehicles: Vehicles that can operate independently without human intervention.
- Artificial intelligence (AI): The development of computer systems that can perform tasks that typically require human intelligence, such as learning, problem-solving, and perception.

#### Conclusion
The Three Laws of Robotics provide a framework for creating robots and autonomous systems that prioritize safety and ethical behavior. Understanding these laws and their implications is essential for anyone interested in the field of robotics or AI. By applying these principles, we can create technologies that benefit society and minimize potential harms.


text: Jalapenos, now the country’s favorite chili pepper, arrived in the U.S. with the initial wave of Tex-Mex cuisines, a new treat already highly popular in Latin America, Asian, Spanish and Caribbean communities. They are considered a “medium-heat” pepper. The heat in jalapeno peppers is due to their active component, capsaicin. This substance can be highly irritating to susceptible individuals causing burning to their throats, tongues and mouth. Avoid touching your eyes after preparing jalapenos. Should you do so, rinse eyes continually and thoroughly with cold water.. Jalapeno peppers are named for the Mexican town, Jalapa in Veracruz state. Texas designated the jalapeño as state pepper in 1995. The US demand for jalapeños rises every year due to the popularity of Mexican and Tex Mex foods. On a hot pepper “heat index”, the jalapeño is considered medium. Jalapenos are rich in vitamins C, A, E and K, plus valuable flavonoids. Continue reading →

1. Classic rainboots: These have a rounded toe and a flat sole, providing enough room for children's feet to move around.
2. Wellington boots: These have a pointed toe and a slight heel, making them suitable for walking on muddy surfaces.
3. Rubber boots: These have a flat sole and a wide opening, making them easy to put on and take off.

Choose a style that suits your child's needs and preferences. For example, if your child needs boots for walking on muddy surfaces, then wellington boots would be the best choice.

Section 3: Materials

The third factor to consider when choosing rainboots for children is the materials used in their production. Look for rainboots made from:

1. Natural rubber: This material is waterproof, flexible, and durable.
2. PVC: This material is also waterproof but can be more rigid than natural rubber.
3. Neoprene: This material provides warmth and insulation, making it suitable for colder weather.

Choose rainboots made from materials that are safe, non-toxic, and environmentally friendly.

Conclusion:

In conclusion, when choosing rainboots for children, consider the size, style, and materials used. Ensure that the rainboots fit well, are comfortable, and made from safe and environmentally friendly materials. By following these guidelines, you can choose the right rainboots for your child's needs and preferences.

Aley

Aley (), is a major city in Lebanon.  It is the capital of the Aley District and fourth largest city in Lebanon.

The city is located on Mount Lebanon, 15 km uphill from Beirut on the freeway to Damascus. Aley has the nickname 'Bride of the Summer resorts' (عروس المصايف) due to its cooler climate during the summer touristic season. Other nicknames include: 'Capital of the Mountain' (عاصمة الجبل); and the 'Lebanese City of Fog' (مدينة الضباب), due to its montane foggy weather.

Demographics
Aley is characterized by having a very wide variety of residents, representing all the Lebanese inclusively.

The permanent residents of Aley are predominantly Druze people. It can be claimed to be the City with the largest Druze population in the world. There also are residents of the Melkite, Eastern Orthodox, and Maronite Christian minorities, and Armenians. Many seasonal residents, especially from Arab Persian Gulf countries, own summer homes here to escape the extreme heat and humidity of the Persian Gulf Region.

Etymology
The word "Aley" derivatives from Aramaic, and means "high place," referring to the City's high altitude above sea level. (from 600m up to 950m)

History
Aley gained prominence upon the completion of the Beirut–Damascus Railway in the mid-1890s. The railroad provided the residents of Beirut easy means of transportation to the mountains, and this made Aley a popular destination to spend the summer months and enjoy its pleasant climate. It was the site of a serious accident on 12 April 1904, when part of the locomotive exploded and the train fell backwards down the 7% grade, killing 8 and seriously injuring another 21.

The city was for a while the summer capital of the Ottoman governors of Mount Lebanon. Kamil Pasha made Aley his capital and organised a Diwan, where he executed a large number of Lebanese and Arab martyrs who sought independence from the Ottomans. Also, a Jewish community once frequented this multi-cultural city, and they maintained a synagogue in Souk Aley, but it has since been abandoned. In 2001, the municipality of Aley began renovating the downtown area, especially its historic souk, and the city quickly revived its role in Lebanon's tourism.

Climate
Aley has a hot-summer Mediterranean climate, with warm and rainless summers, mild autumns and springs, and cool rainy winters. Snow can occasionally fall in colder years. The city is known in Lebanon for its often foggy weather.

Tourism
Aley is a major tourist destination in Lebanon and the Middle East. Its location and climate made it a favorable venue for shopping and dining, especially for wealthy Arabs from Persian Gulf states. This resort city with its increasing number of tourists and visitors has become the most flourishing resort in Mount Lebanon, and thus has garnered its historical name as "The Bride of Summers". The "Souk Aley" is a relatively long historical boulevard lined with palm trees; there are numerous redroofed stone houses erected on the east side of the street while several street cafes, outdoor restaurants, and nightlife pubs occupy its western side. In addition to these, there are tens of antique shops and retail boutiques along the street, which forms the heart of Aley. Aley also hosts a well-known casino and many public swimming pools like the Piscine Aley, Country Club and Heritage. There's also many hotels like the Highland and the Golden Tulip that has a bowling arena and a public swimming pool and spa. There's also malls in Aley like the Aley Center, and many Lebanese and international restaurants.

Aley is the capital of the Aley District and it has 18 municipality members. In 2009 the municipality joined the Yasa in a safety program to reduce the rate of accidents.

Educational and Health Institutions
The city contains 14 schools, 4 public and 10 private. The largest, oldest, and most important of these schools is The Universal College in Aley (UCA) which is considered one of the best schools in the country. It was built in 1907 by Mr. Shebl Khoury.

Lesson: Introduction to Toothpaste

**Objective:** Understand the basic components of toothpaste and how they work to maintain dental hygiene.

**Introduction:** Toothpaste is a crucial part of our daily oral hygiene routine. It helps us maintain good dental health by removing plaque, freshening breath, and preventing cavities. In this lesson, we will explore the different components of toothpaste and how they work together to keep our teeth clean and healthy.

**Section 1: Components of Toothpaste**

Toothpaste contains several ingredients that work together to clean and protect our teeth. Some of the key components include:

- Water: This is the base of toothpaste and helps to dissolve other ingredients.
- Abrasives: These are substances that help remove stains and plaque from teeth. They can be made from materials like calcium carbonate or silica.
- Fluoride: This is a mineral that helps strengthen tooth enamel and prevent cavities by remineralizing the teeth.
- Surfactants: These are substances that reduce the surface tension between toothpaste and teeth, allowing the toothpaste to spread evenly over the teeth.
- Flavors: Toothpaste contains flavors that make it taste pleasant while brushing.
- Colors: Toothpaste contains colors that make it appealing to look at.
- Preservatives: These are added to toothpaste to prevent bacterial growth.

**Section 2: How Toothpaste Works**

Toothpaste works by combining these components to clean and protect our teeth. When we brush our teeth, the abrasives in toothpaste help remove plaque and stains. The fluoride in toothpaste strengthens tooth enamel and prevents cavities by remineralizing the teeth. The surfactants in toothpaste help the toothpaste spread evenly over the teeth, allowing it to reach all areas. Finally, the flavors and colors in toothpaste make it taste and look appealing while brushing.

**Section 3: Practical Examples**

Let's consider a few practical examples to see how toothpaste works in real life. Suppose you have a piece of food stuck between your teeth. Brushing your teeth with toothpaste will help remove the food because the abrasives in toothpaste scrub away the food particles. Additionally, the fluoride in toothpaste will help prevent cavities by remineralizing the teeth and strengthening the enamel.

Another example is when you have a bad breath. Brushing your teeth with toothpaste will help freshen your breath because the abrasives remove plaque and debris that can cause bad breath. Furthermore, the minty flavor in toothpaste can help mask any odors.

**Conclusion:** In conclusion, toothpaste is an essential component of our oral hygiene routine. By understanding the components of toothpaste and how they work together, we can make informed decisions about which toothpaste to use and how to use it effectively. Remember to brush twice a day for lasting sensitivity protection and healthier teeth!
