Wavelength- and amplitude-modulated photoacoustics: comparison of simulated and measured spectra of higher harmonics.
Photoacoustic (PA) spectra generated by current modulation of a distributed feedback diode laser (DFB-DL) were measured for the ammonia absorption line at 1.53 microm and calculated using absorption spectra taken from a database. The algorithm is based on a combined amplitude- and wavelength-modulation (AM-WM) scheme. The spectral characteristics of the DFB-DL were determined by comparing simulated spectra with Fourier transform infrared measurements. PA spectra were measured and simulated from the first to fourth harmonic and a variation of the modulation depth with modulation frequency was observed. It was found that combined AM-WM modulation may produce larger PA signals than separate AM or WM detection for the first harmonic.

Lesson: Introduction to Photoacoustic Spectroscopy

**Objective:** To introduce students to the concept of photoacoustic spectroscopy and its applications in chemistry and material science.

**Glossary:**
- Photoacoustic spectroscopy (PA): A technique used to study the absorption of light by molecules through the measurement of the sound waves produced when a sample is illuminated with light.
- Distributed feedback diode laser (DFB-DL): A type of laser that uses a grating to create a single mode of emission.
- Amplitude modulation (AM): A method of modulating the intensity of a signal.
- Wavelength modulation (WM): A method of modulating the wavelength of a signal.
- Fourier transform infrared (FTIR) spectroscopy: A technique used to identify the chemical composition of a sample by measuring the wavelengths of light absorbed by the sample.

**Introduction:** Photoacoustic spectroscopy is a powerful analytical technique used to study the absorption of light by molecules. It is based on the principle that when a sample is illuminated with light, it produces sound waves that can be measured and analyzed to determine the properties of the sample. In this lesson, we will explore the basics of photoacoustic spectroscopy and its applications in chemistry and material science.

**Section 1: Basic Principles of Photoacoustic Spectroscopy**

**Theory:** When a sample is illuminated with light, the energy from the photons is absorbed by the molecules in the sample. This absorption of energy causes the molecules to vibrate, producing sound waves. These sound waves can be detected and analyzed to determine the properties of the sample, such as its chemical composition and structure.

**Practice:** To demonstrate the basic principles of photoacoustic spectroscopy, we can perform an experiment using a simple setup consisting of a laser, a sample, and a microphone. First, we shine the laser onto the sample and record the sound waves produced. Then, we can analyze the sound waves to determine the properties of the sample.

**Questions:** What is the relationship between the energy of a photon and its wavelength? How does the absorption of a photon by a molecule affect the vibration of the molecule?

**Answers:** The energy of a photon is directly proportional to its frequency, which is inversely proportional to its wavelength. When a photon is absorbed by a molecule, it transfers its energy to the molecule, causing the molecule to vibrate. The vibration of the molecule produces sound waves that can be detected and analyzed.

**Section 2: Modulation Techniques in Photoacoustic Spectroscopy**

**Theory:** There are two main modulation techniques used in photoacoustic spectroscopy: amplitude modulation (AM) and wavelength modulation (WM). In AM, the intensity of the light source is modulated, while in WM, the wavelength of the light source is modulated. Combined AM-WM modulation involves both modulating the intensity and wavelength of the light source.

**Practice:** To demonstrate the difference between AM and WM modulation, we can perform an experiment using a DFB-DL and a sample. First, we modulate the intensity of the laser and record the PA signals produced. Then, we modulate the wavelength of the laser and repeat the experiment. Finally, we modulate both the intensity and wavelength of the laser and repeat the experiment.

**Questions:** What is the difference between AM and WM modulation? Which modulation technique is better for detecting lower frequency PA signals?

**Answers:** AM modulation involves modulating the intensity of the light source, while WM modulation involves modulating the wavelength of the light source. Combined AM-WM modulation involves both modulating the intensity and wavelength of the light source. AM modulation is better for detecting lower frequency PA signals.

**Section 3: Applications of Photoacoustic Spectroscopy**

**Theory:** Photoacoustic spectroscopy has a wide range of applications in chemistry and material science, including the identification of chemical compounds, the determination of molecular structures, and the study of surface properties.

**Practice:** To demonstrate the applications of photoacoustic spectroscopy, we can perform an experiment using FTIR spectroscopy and a sample. First, we obtain the FTIR spectrum of the sample and analyze it to determine its chemical composition. Then, we perform PA spectroscopy on the sample and compare the results to the FTIR spectrum.

**Questions:** How does the absorption of light by molecules relate to their chemical composition? Can PA spectroscopy be used to study the surface properties of a material?

**Answers:** The absorption of light by molecules is related to their chemical composition because different molecules absorb light at different wavelengths. PA spectroscopy can be used to study the surface properties of a material by analyzing the PA signals produced by the material's surface.

**Conclusion:** In this lesson, we have explored the basic principles of photoacoustic spectroscopy, modulation techniques, and applications in chemistry and material science. By understanding these concepts, students can apply their knowledge to new problems and contribute to the advancement of scientific research.

Lesson: Introduction to Algebra

### Section 1: What is Algebra?
Algebra is a branch of mathematics that uses symbols, letters, and operations to represent and solve problems involving quantities, relationships, and functions. It is used in many fields, including science, engineering, and finance.

### Section 2: Why Study Algebra?
Studying algebra helps develop critical thinking and problem-solving skills. It also provides a foundation for more advanced mathematics, such as calculus and trigonometry. Understanding algebra can help you make sense of the world around you by analyzing patterns, making predictions, and solving real-world problems.

### Section 3: How Does Algebra Work?
Algebra uses variables, which represent unknown values or quantities. Operations, such as addition, subtraction, multiplication, and division, are performed on these variables to solve equations. Equations are statements that two expressions are equal, and they can be used to solve for unknown values.

For example, consider the equation 2x + 5 = 10. In this equation, x represents an unknown value, and the goal is to find what x is. By isolating x on one side of the equation and simplifying, we get x = 5. This means that when we substitute x with 5, the equation becomes true.

### Section 4: Practical Examples
Let's say you have a recipe that calls for 2 cups of flour, but you only have 1 cup left in your pantry. How much more flour do you need to buy? Using algebra, we can set up an equation: 2x + 1 = 0, where x represents the amount of flour needed. Solving for x, we get x = -1/2. However, since we cannot have negative flour, we need to buy 2 cups of flour.

### Section 5: Glossary
- Variable: A letter or symbol representing an unknown value or quantity.
- Operation: An arithmetic procedure that performs a specific task, such as addition, subtraction, multiplication, or division.
- Equation: A statement that two expressions are equal.
- Isolate: To separate a variable from other terms in an equation.
- Simplify: To make an expression or equation easier to understand or solve by removing unnecessary steps or terms.

### Conclusion
Understanding algebra is essential for developing critical thinking and problem-solving skills. By mastering algebraic concepts, you can solve real-world problems and make sense of patterns and relationships in the world around you.

For the first time, scientists have succeeded in triggering skeletal muscle contraction using pulses of light. This shows exciting promise in potential paralysis treatments. Recently, researchers from the University of Bonn have demonstrated the use of light to stimulate the opening [and closing] of a mouse’s voice box or larynx (download the short video here).

The method is based on a technique called optogenetics, where nerve cells are genetically modified to incorporate a gene that makes them respond to light . This allows scientists to mimic the effects of a nerve impulse by shining light on the modified cells. Optogenetics is currently used to study the transmission of signals in the nervous system, but this new approach highlights a potential medical use for the technology.

Philipp Sasse and his team at the University of Bonn have used optogenetics in muscle cells, and shown that muscle fibres isolated from their genetically modified mice contract when exposed to light . In the intact muscle, the light pulses caused sustained contraction and opening of the larynx (see the video below). The group also demonstrated the potential of this as a treatment by successfully transferring the necessary gene into the muscle of a normal mouse. This could be achieved in humans through existing gene therapy technology.

The researchers opted to study the larynx as they recognized that optogenetics held the potential to allow a treatment for laryngeal paralysis to be developed. This condition most commonly occurs due to nerve damage following injury, surgery or stroke, and can cause difficulty speaking, breathing and swallowing. Using light instead of electrical stimulation (which is already used to treat some forms of paralysis) allows much greater precision in the area to be stimulated. This is particularly important in areas like the larynx, where the muscles that control opening and closing are situated very close to each other.

Once the technique is refined, optogenetic muscle stimulation could be used to treat a range of disorders caused by a breakdown of communication from the nerves to the muscles. It also provides a new way of studying detailed features of muscle contraction, and so will be a useful tool in future research.

Lesson: Introduction to Optogenetics

### Section 1: Theoretical Concepts
Optogenetics is a technique used in molecular biology and neuroscience to study the function of neurons and other cell types. It involves the use of light to control the activity of specific cells in living organisms. The basic idea behind optogenetics is to genetically modify cells to make them sensitive to light, so that their activity can be controlled by shining light on them.

In this lesson, we will learn about the basic principles of optogenetics, how it works, and its potential applications in medicine.

### Section 2: Practical Examples
To understand how optogenetics works, let's consider an example. Suppose we want to study the activity of a particular group of neurons in the brain. We can genetically modify these neurons to make them sensitive to light. Once these neurons are modified, we can shine a light on them to activate them, and turn off the light to deactivate them. By controlling the activity of these neurons in this way, we can study their function and role in various brain processes.

Now, let's consider another example. Suppose we want to develop a treatment for paralysis. One approach could be to use optogenetics to stimulate the muscles of a paralyzed person. We can genetically modify the muscle cells to make them sensitive to light, and then shine light on them to cause them to contract. This could potentially help paralyzed people regain some movement in their muscles.

### Section 3: Self-Debating Discussions
One potential concern with using optogenetics in medicine is the risk of unintended side effects. For example, if we modify too many cells to be sensitive to light, it could potentially cause harm to the patient. Another concern is the potential for misuse of this technology. If we can control the activity of cells with light, it raises questions about the potential for abuse or manipulation.

On the other hand, there are also many potential benefits to using optogenetics in medicine. For example, it could potentially help us develop new treatments for paralysis, or help us better understand the function of certain cells in the body. Additionally, the technology has already been tested in animals and has shown promising results, suggesting that it could eventually be used safely and effectively in humans.

Glossary:
- Optogenetics: A technique used in molecular biology and neuroscience to study the function of neurons and other cell types by making them sensitive to light.
- Genetic modification: The process of altering an organism's genetic material to introduce new characteristics or traits.
- Light: A form of electromagnetic radiation that travels in waves and can be detected by the human eye.
- Muscle cells: Cells that are responsible for producing movement in the body.
- Larynx: A structure in the throat that contains the vocal cords and helps produce sound.

Conclusion:
In this lesson, we learned about the basics of optogenetics, how it works, and its potential applications in medicine. We also considered some of the potential risks and benefits of using this technology. By understanding the principles of optogenetics, we can better appreciate its potential to revolutionize our understanding of the brain and develop new treatments for various medical conditions.

Lesson: The Impact of Isolation on Mental Health

Introduction:
In today's fast-paced world, technology has made it easier for people to connect with each other. However, despite all these advancements, mental health issues like depression and anxiety are on the rise. One of the reasons for this could be the increase in isolation among individuals. In this lesson, we will explore the impact of isolation on mental health and learn ways to cope with it.

Section 1: Understanding Isolation

Topic 1: What is isolation?
Isolation refers to the state of being alone or cut off from others. It can be physical, emotional, or social isolation.

Topic 2: Why does isolation affect mental health?
Isolation can affect mental health because it deprives individuals of social interaction, which is essential for their well-being. Humans are social creatures, and they need socialization to feel connected and valued. When this need is not met, it can lead to feelings of loneliness, depression, and anxiety.

Topic 3: Who is more prone to isolation?
People who live alone, work alone, or have limited social interactions are more prone to isolation. Additionally, people with mental health issues, physical disabilities, or chronic illnesses may also experience isolation.

Section 2: Coping with Isolation

Topic 1: Ways to combat isolation
There are several ways to combat isolation, such as:
- Engaging in social activities, even if it's online
- Joining clubs or groups that share similar interests
- Reaching out to friends and family members
- Participating in community events
- Volunteering for a cause you care about

Topic 2: Self-care techniques
Self-care techniques like meditation, exercise, and journaling can also help combat isolation. These activities help individuals focus on themselves and improve their mental health.

Topic 3: Seeking professional help
If isolation is affecting your mental health, it's essential to seek professional help. A mental health professional can guide you through the process of overcoming isolation and provide you with tools to manage your mental health.

Section 3: Real-life examples

Example 1: John, a software engineer, works from home due to the pandemic. He feels isolated and struggles to connect with his colleagues virtually. To combat isolation, he joins an online book club and starts walking every day.

Example 2: Sarah, a college student, lives in a dormitory. She feels lonely and misses her family. To combat isolation, she calls her parents regularly and participates in campus events.

Conclusion:
Isolation can have a significant impact on mental health. However, there are ways to combat it. By engaging in social activities, practicing self-care, and seeking professional help, individuals can overcome isolation and improve their mental health. Remember, it's essential to prioritize your mental health and seek help when needed.

If I were running the Celtics, I'd face the fact that the team cannot contend for a title in the next 3-5 years the way things are going. Maybe there will be a one or two year window when Green and Jefferson hit their prime and Pierce is not yet too old, but that's being really optimistic. We're talking about a team that has already been in the lottery for two years, and will probably stay there a while longer.

A trade with the Bulls for #2 might be the best answer for them. How much cap space will the Bulls have to absorb salary? Without knowing that, it's hard to name a specific deal, but a possibility might be:

Pierce + LaFrentz for Duhon + Harrington + #2

New lineups might be:

Duhon
Szczerbiak/Green
Morrison
Jefferson/#7
Perkins

That's a team with some players that are lovable enough for Boston to show support to during their awful next two years, and they get the added bonus of a great ticket for the Oden lottery.

Bulls could be

Hinrich
Pierce/Gordon
Noccioni/Deng
Chandler/#16
LaFrentz

Or... the Celtics could continue to be a lottery team with Pierce, and maybe he'll play a mentoring role to the young guys. Who knows.

Lesson: Introduction to NBA Trade Analysis

## Chapter 1: What is an NBA Trade?
An NBA trade is a transaction between two teams in the National Basketball Association (NBA) where players, draft picks, and cash considerations are exchanged for each other. Trades can happen at any point during the season and can help teams improve their roster or acquire assets for future use.

## Chapter 2: Why do teams make trades?
Teams make trades for several reasons, including:

1. To improve their roster: A team may feel that they need to add certain players or draft picks to improve their chances of winning games.

2. To clear cap space: Teams may want to free up salary cap space to sign free agents or make trades with other teams.

3. To acquire draft picks: Teams may trade away players for future draft picks, which can help them build for the future.

4. To shed salary: Teams may trade away players to reduce their payroll and save money on luxury taxes.

## Chapter 3: How do trades work?
Trades in the NBA involve multiple parties, including the teams involved, the players, and the league office. Here's a step-by-step breakdown of how trades work:

1. Teams agree to a trade: Two teams must agree to a trade before it can be executed. This often involves negotiations between team executives and agents representing the players involved.

2. League approval: Once both teams agree to a trade, it must be approved by the league office. The league will review the trade to ensure that it complies with league rules and that all parties involved are eligible to be traded.

3. Player physicals: Once the league approves the trade, the players involved must undergo physical examinations to ensure that they are healthy and able to play.

4. Contracts: If the trade involves players with expiring contracts or players who are free agents, the new team must sign them to new contracts.

## Chapter 4: Analyzing an Example Trade
Let's take a look at an example trade:

Pierce + LaFrentz for Duhon + Harrington + #2

In this trade, the Boston Celtics would send Paul Pierce and Raef LaFrentz to the Chicago Bulls in exchange for Chris Duhon, Al Harrington, and the #2 overall pick in the upcoming NBA Draft.

Pros:
- The Celtics would be able to add a top-two pick in the draft, which could help them land a potential star player.
- The Bulls would be adding a veteran leader in Pierce, who could mentor their young players.

Cons:
- The Celtics would be giving up a lot of talent and experience in this trade.
- The Bulls would be taking on LaFrentz's contract, which is not insignificant.

Overall, this trade would be a significant move for both teams, and it would have long-term implications for their respective futures.

Lesson: Understanding High-Yield Otolaryngology Topics

Introduction:
Otolaryngology is a medical specialty that focuses on the diagnosis and treatment of ear, nose, and throat disorders. This lesson will cover high-yield otolaryngology topics, which are essential for understanding the basics of this field.

Section 1: Anatomy and Physiology

Topic 1: Ear Anatomy
The ear is divided into three parts: the outer ear, middle ear, and inner ear. The outer ear consists of the pinna (auricle) and the ear canal. The middle ear contains the eardrum and three small bones called the ossicles. The inner ear includes the cochlea and the vestibular system.

Topic 2: Nasal Anatomy
The nasal cavity is divided into two nostrils (anterior nares) and the rest of the cavity (posterior nares). The nasal septum separates the two nostrils. The nasal cavity contains the olfactory epithelium, which is responsible for the sense of smell.

Topic 3: Throat Anatomy
The throat is divided into the pharynx, larynx, and esophagus. The pharynx is a muscular tube that connects the mouth and nose to the larynx. The larynx contains the vocal cords and is responsible for voice production. The esophagus is a muscular tube that connects the mouth to the stomach.

Section 2: Common Disorders

Topic 1: Acute Otitis Media (AOM)
AOM is an infection of the middle ear that can cause pain, fever, and hearing loss. It is usually caused by bacteria and can be treated with antibiotics.

Topic 2: Sinusitis
Sinusitis is an inflammation of the sinuses, which can be caused by allergies, infections, or other factors. Symptoms include facial pain, headache, and congestion. Treatment may include medications, nasal sprays, or surgery.

Topic 3: Laryngitis
Laryngitis is an inflammation of the larynx, which can cause hoarseness, sore throat, and difficulty speaking. It can be caused by overuse of the voice, infections, or other factors. Treatment may include resting the voice, drinking fluids, and taking medications.

Section 3: Diagnosis and Treatment

Topic 1: Diagnostic Tests
Diagnostic tests for ear, nose, and throat disorders may include hearing tests, imaging studies, and endoscopic examinations. These tests help to identify the cause of symptoms and determine the best course of treatment.

Topic 2: Treatment Options
Treatment options for ear, nose, and throat disorders depend on the specific condition and its severity. They may include medications, surgery, or lifestyle changes. In some cases, no treatment is necessary, and symptoms will resolve on their own.

Conclusion:
Understanding high-yield otolaryngology topics is essential for anyone interested in learning about ear, nose, and throat disorders. By studying anatomy and physiology, common disorders, and diagnostic and treatment options, you can develop a strong foundation in this medical specialty.

text: A regime-switching approach to the study of speculative attacks: A focus on EMS crises. This paper implements a regime-switching framework to study speculative attacks against EMS currencies during 1979-1993. To identify speculative episodes, we model exchange rates, reserves, and interest rates as time series subject to discrete regime shifts between two possible states: "tranquil" and "speculative". We allow the probabilities of switching between states to be a function of fundamentals and expectations. The regime-switching framework improves the ability to identify speculative attacks vis-à-vis the indices of speculative pressure used in the literature. The results also indicate that fundamentals (particularly budget deficits) and expectations drive the probability of switching to a speculative: 299-334.

Lesson Title: Regime-Switching Approach to Economic Analysis

Introduction:
In this lesson, we will learn about a regime-switching approach to economic analysis. This approach is useful for studying economic events such as speculative attacks. We will use the example of the European Monetary System (EMS) crises to illustrate how this approach works.

Core Value:
The core value of this approach is that it allows us to identify speculative episodes by modeling exchange rates, reserves, and interest rates as time series subject to discrete regime shifts. This means that we can switch between two possible states - "tranquil" and "speculative" - and analyze how fundamentals and expectations drive the probability of switching.

Section 1: Theory and Concepts

Topic 1: Regime-Switching Models
- A regime-switching model is a type of econometric model that allows for the analysis of economic time series data subject to discrete regime shifts.
- These models are particularly useful for studying economic events such as speculative attacks, where there is a sudden shift in market behavior.
- In a regime-switching model, the probability of switching between states can be a function of fundamentals (such as budget deficits) and expectations.

Topic 2: Identifying Speculative Episodes
- Speculative episodes are periods of heightened volatility in financial markets, where investors engage in speculative behavior.
- Using a regime-switching approach, we can identify speculative episodes by modeling exchange rates, reserves, and interest rates as time series subject to discrete regime shifts.
- By doing so, we can improve our ability to identify speculative attacks vis-à-vis the indices of speculative pressure used in the literature.

Section 2: Practical Examples

Topic 1: The EMS Crises
- The EMS was a system of fixed exchange rates that existed in Europe from 1979 to 1993.
- During this time, there were several crises where the value of the EMS currencies came under attack from speculators.
- Using a regime-switching approach, we can study these speculative attacks by modeling exchange rates, reserves, and interest rates as time series subject to discrete regime shifts.

Topic 2: Applying the Regime-Switching Approach
- To apply the regime-switching approach, we need to first identify the key variables that we want to model.
- In the case of the EMS crises, we might choose to model exchange rates, reserves, and interest rates as our key variables.
- Next, we need to identify the possible states that these variables can switch between - in this case, we might choose "tranquil" and "speculative" as our two possible states.
- Finally, we need to estimate the probabilities of switching between these states based on fundamentals (such as budget deficits) and expectations.

Section 3: Self-Debating Discussions

Topic 1: The Importance of Fundamentals
- In the regime-switching approach, fundamentals play an important role in determining the probability of switching between states.
- For example, in the case of the EMS crises, high budget deficits may have increased the likelihood of speculative attacks.
- As a class, we can debate the importance of fundamentals in driving economic events such as speculative attacks.

Topic 2: The Role of Expectations
- In addition to fundamentals, expectations also play a role in determining the probability of switching between states in a regime-switching model.
- For instance, if investors expect a currency to devalue, they may engage in speculative behavior, driving up the probability of switching to a speculative state.
- As a class, we can discuss the importance of expectations in driving economic events and how they may interact with fundamentals.

Conclusion:
In this lesson, we have learned about a regime-switching approach to economic analysis. This approach is useful for studying economic events such as speculative attacks. We used the example of the EMS crises to illustrate how this approach works. By modeling exchange rates, reserves, and interest rates as time series subject to discrete regime shifts, we can identify speculative episodes and analyze how fundamentals and expectations drive the probability of switching. We also engaged in self-debating discussions on the importance of fundamentals and expectations in driving economic events. By applying this approach, we can gain a deeper understanding of economic events and apply our skills to new problems.

Phenanthrene derivatives for use in liquid-crystalline mixtures have already been disclosed in DE-A 19500768, WO 98/27043, WO 98/27035 or WO 99/24385.
However, since the development of liquid-crystal mixtures can in no way be regarded as complete, display manufacturers are interested in a wide variety of components for mixtures.
In particular, liquid-crystal mixtures are required which have a very broad operating temperature range, but also a very low threshold voltage, for example for use in automobiles, in which a temperature range from xe2x88x9240 to 100xc2x0 C. can easily occur, but also for portable devices such as mobile telephones and notebook PCs. Moreover, it appears that the tendency toward moving images can be realized with nematic liquid crystals only when the electrode separation of such LCDs is reduced, since the response times are inversely proportional to the square of the electrode separation. This in turn inevitably results in a reduction in brightness and contrast, unless liquid-crystal mixtures having a high optical anisotropy (delta n) value are used. However, materials having a high optical anisotropy usually have high viscosities as well and are thus unfavorable for the objective intended.
There is thus a need for novel, suitable liquid-crystal mixtures and mixture components for these which have a high clearing point and a high optical anisotropy and at the same time have a relatively low rotational viscosity.
It is therefore the object of the present invention to provide novel components for use in nematic or cholesteric liquid-crystal mixtures which have positive dielectric anisotropy values combined with a favorable viscosity/clearing point ratio. Moreover, the compounds should have a high light and UV stability and thermal stability. They should furthermore be suitable for realizing high voltage holding ratios (VHR). They should also be readily obtainable synthetically and thus potentially inexpensive.
It has now been found that these requirements are satisfied in a particular manner by compounds of the formula (I)
R1xe2x80x94Axe2x80x94Z1xe2x80x83xe2x80x83(I)
in which:
R1 is an alkyl radical having 1 to 8 carbon atoms or an alkenyl radical having 2 to 8 carbon atoms, where, in each case, one (nonterminal) xe2x80x94CH2xe2x80x94 group may also be replaced by xe2x80x94Oxe2x80x94 or xe2x80x94C(xe2x95x90O)Oxe2x80x94 and/or one or more H may be replaced by F
A is phenanthrene-2,7-diyl or 9,10-dihydrophenanthrene-2,7-diyl
Z1 is F, OCHxF3xe2x88x92x or CHxF3xe2x88x92x, where, in each case, x is 0, 1 or 2, OC2HzF5xe2x88x92z or C2HzF5xe2x88x92z, where, in each case, z is 0, 1, 2, 3 or 4, CHxe2x95x90CF2 or Cl,
with the proviso that 2-fluoro-7-methoxy-phenanthrene is excluded.
Preference is given to those compounds of the formula (I) in which
R1 is an alkyl radical having 2 to 7 carbon atoms or an alkenyl radical having 2 to 7 carbon atoms, where, in each case, one (nonterminal) xe2x80x94CH2xe2x80x94 group may also be replaced by xe2x80x94Oxe2x80x94 and/or one or more H may be replaced by F
A is phenanthrene-2,7-diyl or 9,10-dihydrophenanthrene-2,7-diyl
Z1 is F, OCF3, CF3, OCHF2, CHF2.
Particular preference is given to those compounds of the formula (I) in which
R1 is an alkyl radical having 2 to 7 carbon atoms or an alkenyl radical having 2 to 7 carbon atoms or an alkyloxy radical having 2 to 6 carbon atoms or an alkenyloxy radical having 2 to 6 carbon atoms

A is 9,10-dihydrophenanthrene-2,7-diyl
Z1 is F, OCF3, CF3.
Special preference is given to
2-ethyl-7-fluoro-phenanthrene
2-fluoro-7-propyl-phenanthrene
2-butyl-7-fluoro-phenanthrene
2-fluoro-7-pentyl-phenanthrene
2-fluoro-7-hexyl-phenanthrene.
Special preference is likewise given to
2-ethyl-7-fluoro-9,10-dihydrophenanthrene

Liquid crystals are used in a wide range of applications, including display technologies such as LCD screens, sensors for detecting changes in temperature or pressure, and optical devices such as lenses and filters.

Section 2: Liquid Crystals in Display Technologies

2.1 How do liquid crystals work in display technologies?
Liquid crystals are used in display technologies such as LCD screens to create images. When an electric field is applied to the liquid crystal, it changes shape and blocks the light passing through it. By controlling the electric field, the amount of light that passes through the liquid crystal can be controlled, creating different shades of gray or colors on the screen.

2.2 What challenges are faced in developing new liquid crystal materials for display technologies?
Developing new liquid crystal materials for display technologies is a challenging task. Scientists need to find materials that have a high optical anisotropy (delta n) value, which means they can reflect light efficiently, and also have low viscosities so that they can respond quickly to changes in the electric field. Additionally, these materials must have a wide operating temperature range and a low threshold voltage.

Section 3: Self-Debating Discussion

3.1 How important are liquid crystals in our daily lives?
Liquid crystals are essential in our daily lives, as they are used in display technologies such as smartphones, tablets, and televisions. They are also used in sensors and optical devices that help us navigate the world around us.

3.2 How can we encourage scientists to continue researching and developing new liquid crystal materials?
To encourage scientists to continue researching and developing new liquid crystal materials, we can support their work through funding and resources, and promote the importance of their research in improving our daily lives. We can also educate the public about the importance of liquid crystals and their applications, which may increase demand for new technologies and materials.

Conclusion:
In conclusion, liquid crystals are unique materials with properties between those of conventional liquids and solid crystals. They have many applications, including display technologies, sensors, and optical devices. Developing new liquid crystal materials for display technologies is a challenging task, but it is essential for advancing our technological capabilities. By understanding the properties of liquid crystals and their applications, we can appreciate the importance of their research and development.

Wards Airfield

Wards Airfield is a former World War II airfield near Port Moresby, Papua New Guinea. The airfield was abandoned after the war and was developed into the Waigani area of Port Moresby.

The airfield was named in honor of Australian Lt. Col. K. H. Ward, who was involved with its construction and was KIA on 27 August 1942, during the fighting at Isurava on the Kokoda Trail. It was also known as "5-Mile or 5-Mile Drome" by Americans, for its distance from Port Moresby.

History
Wards Airfield (Ward's Strip) was built for heavy bombers and transport planes. By 1943, it was the busiest aerodrome in the southern hemisphere. Mainly used for cargo aircraft and larger planes, Ward's was nearest to Jackson Airfield (7 Mile Drome), and at its height, its taxiways actually connected with those of 7-mile.

The major operational organization at Wards Airfield was the Headquarters, 54th Troop Carrier Wing (3 May 1943 – 18 April 1944).  Operational C-47 Skytrain groups and squadrons assigned to the airfield were:

 317th Troop Carrier Group            (30 September 1943 – April 1944)
 374th Troop Carrier Wing (December 1942-7 October 1943)
 375th Troop Carrier Group             (December 1942 – 7 October 1943)
 6th Troop Carrier Squadron, 13 October 1942 – 2 October 1943
 21st Troop Carrier Squadron, 18 February-28 September 1943
 22d Troop Carrier Squadron, 24 January-4 October 1943
 33d Troop Carrier Squadron, 28 December 1942 – 5 October 1943

Several Reconnaissance groups were assigned to Wards to support Fifth Air Force operations:

 6th Reconnaissance Group  (10 December 1943 – 17 February 1944)
 71st Reconnaissance Group      (7 November 1943 – 20 January 1944)

In addition the 90th Bombardment Group also based two B-24 Liberator squadrons at the airfield.

 320th Bombardment Squadron, 10 February – December 1943
 321st Bombardment Squadron, 10 February – December 1943

Royal Australian Air Force units stationed at the airfield were the 9th Group, 22nd Squadron (A-20) and 30th Squadron (Beaufighter).

General Kenney's Headquarters, V Fighter Command was located at the airfield between December–January 1942.  Reportedly, its cement slab foundations still remain today, located on a hill behind the airfield. A large 5th Air Force insignia and USAAF star, drawn into the concrete.   Concrete steps, a garden and path that went up the ridge towards the HQ. In the 1980s traces of the paint still remained.  Today, both the 5th AF logo and USAAF are partially broken, and the area is overgrown, but it still offers commanding views and an impressive remnant of the American era at the airfield.

This marking overlooks the Chinese Embassy. To visit the slab, drive down Sir John Guise Drive, cross the intersection with Independence Way and Godwit Street and keep going in the direction of the golf club.  When that road begins to make a left turn, there is a hill on your right.

Wards Airfield was also the home of the USAAF 27th Air Depot. This group was responsible for assembling crated aircraft delivered by ship docked in Fairfax Harbor from the United States.  Brand new aircraft were delivered to Port Moresby assembled and then flown to other bases. Ships continued to dock at Port Moresby until mid-1945 when transports switched to Manila Bay.  For pilots wishing to pick up a brand new plane, they would have to go all the way back to Port Moresby

Current status
One can still drive along the main runway. In the post war years, most of its aircraft revetments were bulldozed flat, and a scrap dealer operated there, melting down aluminum from aircraft remains. Locals would siphon gasoline from the aircraft fuel tanks for their own use well into the 1950s.

Lesson: World War II Airfields in Papua New Guinea

Introduction
During World War II, many airfields were built in Papua New Guinea to support the Allied forces in their fight against the Axis powers. One such airfield was Wards Airfield, which was named after an Australian soldier who was killed in action during the fighting on the Kokoda Trail. In this lesson, we will learn about the history and significance of Wards Airfield and other airfields in Papua New Guinea during World War II.

Section 1: History of Wards Airfield

Wards Airfield was built during World War II as a base for heavy bombers and transport planes. It was located near Port Moresby and was named after Australian Lt. Col. K. H. Ward, who was involved with its construction and was killed in action during the fighting on the Kokoda Trail. The airfield was also known as "5-Mile or 5-Mile Drome" by Americans due to its distance from Port Moresby.

By 1943, Wards Airfield had become the busiest aerodrome in the southern hemisphere, mainly used for cargo aircraft and larger planes. Its taxiways even connected with those of 7-mile, making it the nearest airfield to Jackson Airfield. The major operational organization at Wards Airfield was the Headquarters, 54th Troop Carrier Wing.

Operational C-47 Skytrain groups and squadrons assigned to the airfield included the 317th Troop Carrier Group, 374th Troop Carrier Wing, and 375th Troop Carrier Group. These groups and squadrons were responsible for transporting troops and supplies during the war.

Section 2: Other Airfields in Papua New Guinea

In addition to Wards Airfield, there were several other airfields in Papua New Guinea during World War II. These included:

1. Jackson Airfield (7 Mile Drome) - This airfield was used primarily by fighter planes and was located just outside of Port Moresby.
2. Lae Airfield - This airfield was built in 1942 and was used by both Japanese and Allied forces during the war.
3. Milne Bay Airfield - Located on the eastern tip of Papua New Guinea, this airfield was used by the Allies to support their campaigns in the region.
4. Nadzab Airfield - This airfield was captured by Australian forces in 1943 and was used as a base for transport planes.

Section 3: Significance of Wards Airfield and Other Airfields in Papua New Guinea

The airfields in Papua New Guinea played a crucial role in the Allied victory during World War II. They allowed for the transport of troops and supplies to the front lines, as well as the provision of air support for ground operations. Additionally, the capture of these airfields by Allied forces was instrumental in disrupting Japanese supply lines and weakening their ability to defend the region.

Conclusion
In this lesson, we have learned about the history and significance of Wards Airfield and other airfields in Papua New Guinea during World War II. We have discussed the role that these airfields played in supporting Allied forces and the importance of their capture in the overall strategy of the war. By understanding the history of these airfields, we can better appreciate the sacrifices made by those who fought and died for our freedom.

text: What is maintenance?.. Maintenance for spouses/civil partners. A spouse/civil partner applying to the court for maintenance must establish that the other spouse/civil partner has failed to provide such maintenance as is proper in the circumstances. The court decides what maintenance is proper in the circumstances of each individual case.. Maintenance for cohabitating couples’.. Maintenance of children.. Who can apply for maintenance?.. Age limits. A dependant child is a child under eighteen years of age, or a child under 23 who is in full time education, or a child of any age who is dependant on its parents due to disability.<<

textbook:
**Maintenance and Support**

Maintenance refers to financial support provided by one spouse/civil partner to another after the breakdown of a marriage or civil partnership. This support is intended to help the receiving spouse/civil partner maintain their standard of living and meet their needs. In this lesson, we will explore the different types of maintenance, who can apply for maintenance, and how the court determines the amount of maintenance to be paid.

**Types of Maintenance**

There are two types of maintenance: temporary and permanent.

1. Temporary Maintenance: This type of maintenance is paid during the divorce or separation process. It is intended to provide financial support to the receiving spouse/civil partner until a final maintenance order is made by the court.

2. Permanent Maintenance: This type of maintenance is paid after the divorce or separation is finalized. It is intended to provide long-term financial support to the receiving spouse/civil partner.

**Who can apply for Maintenance?**

Either spouse/civil partner can apply for maintenance. However, the court will only grant maintenance if the applicant can show that they require financial support and that the other spouse/civil partner has the ability to pay.

**Age Limits**

The age limit for a dependant child is eighteen years old. However, if the child is still in full-time education, the age limit is twenty-three. Additionally, a child of any age can be considered dependant on their parents due to disability.

**How is Maintenance Determined?**

The court will consider several factors when determining the amount of maintenance to be paid. These factors include:

1. The income and earning capacity of both spouses/civil partners.
2. The financial resources and needs of both spouses/civil partners.
3. The age and health of both spouses/civil partners.
4. The standard of living enjoyed by the family during the marriage or civil partnership.
5. The contribution made by each spouse/civil partner to the family's welfare.

**Practical Examples**

Example 1: John and Sarah have been married for ten years. Sarah stayed at home to raise their two children while John worked. Now that they are getting divorced, Sarah needs financial support to pay for her living expenses. The court orders John to pay temporary maintenance of $500 per month until a final maintenance order is made.

Example 2: Tom and Lisa have been married for twenty-five years. Lisa gave up her career to take care of their three children. Now that they are getting divorced, Tom is ordered to pay permanent maintenance of $2000 per month to Lisa to help her maintain her standard of living.

**Conclusion**

In conclusion, maintenance is an important aspect of divorce or separation proceedings. It is intended to provide financial support to the spouse/civil partner who needs it. The court will consider several factors when determining the amount of maintenance to be paid. By understanding the different types of maintenance, age limits, and how maintenance is determined, you can better navigate the legal process.

Lesson Title: Symptom Clustering Algorithm for Efficient Diagnosis of Multiple Disorders

Introduction:
In this lesson, we will learn about a new representation and algorithm called symptom clustering, which is used to diagnose multiple disorders efficiently. We will understand how this approach differs from the existing candidate generation approach and how it achieves efficiency by generating aggregates of candidates rather than individual candidates.

Section 1: Understanding Symptom Clustering

Topic 1: Representation and Algorithm
- Symptom clustering is a representation and algorithm used to diagnose multiple disorders efficiently.
- It partitions symptoms into causal groups, in contrast to the existing candidate generation approach, which assembles disorders or candidates.
- Symptom clustering achieves efficiency by generating aggregates of candidates rather than individual candidates and by representing them implicitly in a Cartesian product form.
- Search criteria of parsimony, subsumption, and spanning narrow the symptom clustering search space, and a problem-reduction search algorithm explores this space efficiently.

Topic 2: Symptom Clustering vs. Candidate Generation
- Symptom clustering partitions symptoms into causal groups, while candidate generation assembles disorders or candidates.
- Symptom clustering generates aggregates of candidates rather than individual candidates and represents them implicitly in a Cartesian product form.
- Candidate generation assembles disorders or candidates explicitly, which leads to a larger search space.
- Symptom clustering narrows the search space using search criteria such as parsimony, subsumption, and spanning.

Section 2: Practical Examples Using Symptom Clustering

Topic 1: Diagnosing Multiple Disorders
- Symptom clustering can be used to diagnose multiple disorders efficiently.
- For example, if a patient has symptoms such as fever, cough, and body aches, symptom clustering can group these symptoms into a respiratory infection.
- This allows doctors to quickly identify the cause of the symptoms and provide appropriate treatment.

Topic 2: Real-World Scenarios
- Symptom clustering can be applied to various real-world scenarios, such as fraud detection, customer segmentation, and image recognition.
- In fraud detection, symptom clustering can group similar transactions together to identify patterns of fraudulent behavior.
- In customer segmentation, symptom clustering can group customers with similar characteristics to target marketing campaigns more effectively.
- In image recognition, symptom clustering can group objects with similar features together to improve object detection accuracy.

Section 3: Self-Debating Discussions

Topic 1: Critical Thinking
- Symptom clustering requires critical thinking to identify the root cause of symptoms and group them into causal groups.
- Doctors must consider various factors such as medical history, family history, and environmental factors to accurately diagnose multiple disorders.
- Similarly, in other scenarios, individuals must use critical thinking to identify patterns and group similar items together.

Topic 2: Problem Solving
- Symptom clustering involves problem-solving to explore the search space efficiently and identify the most likely cause of symptoms.
- Doctors must use problem-solving skills to determine the most effective treatment plan based on the diagnosis.
- Similarly, in other scenarios, individuals must use problem-solving skills to identify the best solution to a problem.

Glossary:
- Causal group: A group of symptoms that share a common cause.
- Cartesian product: A mathematical operation that takes the product of two sets, where each element of the first set is combined with every element of the second set.
- Candidate generation: An approach that assembles disorders or candidates explicitly.
- Parsimony: The principle of selecting the simplest explanation that fits the data.
- Subsumption: The principle of including specific cases under general cases.
- Spanning: The principle of covering all possible cases.

Conclusion:
Symptom clustering is an efficient approach to diagnose multiple disorders by grouping symptoms into causal groups. It achieves efficiency by generating aggregates of candidates rather than individual candidates and by representing them implicitly in a Cartesian product form. By understanding the principles of symptom clustering, we can apply these skills to various real-world scenarios, such as fraud detection, customer segmentation, and image recognition.


text: X-chromosome polysomy in the male. Summary. A review of 569 male patients with X-chromosome polysomies (544 Klinefelter and 25 patients with other types of X-chromosome polysomy) is presented here. These patients were detected among the 77000 persons karyotyped in the Leuven cytogenetic center between the years 1966 and 1987. In the group of 544 Klinefelter patients special attention was paid to (1) the age at diagnosis, (2) social and marital status of the postpubertal males, (3) physical and intellectual abilities of the prepubertal boys, (4) delineation of the concurrence of Klinefelter syndrome and fragile X syndrome, and (5) the frequency of malignancies. In 25 patients with other X-chromosome polysomies (2 n≥48 chromosomes) genotype/phenotype correlation is reviewed, especially for the patients with 48,XXYY and 49,XXXXY karyotypes. Finally, double aneuploidy and rare structural X-chromosome aberrations are briefly discussed.

Lesson: Understanding Chromosomes and Genetic Disorders

Introduction:
Chromosomes are structures found in the nucleus of cells that contain genetic information. Genetic disorders occur when there are changes or mutations in the chromosomes that affect normal development and functioning of the body. In this lesson, we will learn about chromosomes and genetic disorders, including X-chromosome polysomy in males.

Section 1: Understanding Chromosomes

Topic 1: What are chromosomes?
Chromosomes are structures found in the nucleus of cells that contain genetic information. They are composed of DNA and proteins called histones. Humans have 46 chromosomes, which are arranged in pairs. One chromosome in each pair is inherited from the mother, and the other is inherited from the father.

Topic 2: How do chromosomes carry genetic information?
Chromosomes carry genetic information in the form of genes. Genes are segments of DNA that code for specific traits, such as hair color or eye shape. There are thousands of genes on each chromosome, and they are arranged in a specific order.

Topic 3: What happens when there are changes in chromosomes?
Changes or mutations in chromosomes can lead to genetic disorders. These changes can occur during cell division, when errors are made in the copying of DNA. Some genetic disorders are caused by missing or extra parts of chromosomes, while others are caused by changes in the genes themselves.

Section 2: X-chromosome Polysomy in Males

Topic 1: What is X-chromosome polysomy?
X-chromosome polysomy is a condition in which a male has more than one X chromosome. This can occur in two main forms: Klinefelter syndrome and other types of X-chromosome polysomy.

Topic 2: What causes X-chromosome polysomy in males?
X-chromosome polysomy in males is usually caused by errors in cell division during the formation of sperm cells. These errors result in sperm cells with an abnormal number of X chromosomes, which can then fertilize an egg cell.

Topic 3: What are the symptoms of X-chromosome polysomy in males?
Symptoms of X-chromosome polysomy in males vary depending on the type of polysomy and the severity of the condition. Some common symptoms include infertility, learning difficulties, and physical abnormalities such as tall stature and gynecomastia (enlarged breast tissue).

Section 3: Genotype/Phenotype Correlation

Topic 1: What is genotype/phenotype correlation?
Genotype/phenotype correlation refers to the relationship between a person's genetic makeup (genotype) and their observable characteristics or traits (phenotype). By studying this relationship, scientists can better understand how genetic disorders develop and how they may be treated.

Topic 2: How is genotype/phenotype correlation studied?
Genotype/phenotype correlation is studied through a combination of laboratory research and clinical observation. Scientists may use techniques such as DNA sequencing and gene expression analysis to study the genetic basis of a disorder, while clinicians observe and document the physical and behavioral traits of patients.

Conclusion:
In this lesson, we have learned about chromosomes and genetic disorders, including X-chromosome polysomy in males. We have explored the basics of chromosomes, genetic information, and genetic disorders, as well as the specifics of X-chromosome polysomy in males and genotype/phenotype correlation. By understanding these concepts, we can better appreciate the complexity of genetic disorders and the importance of continued research in this field.

text: I've been studying the defences of poetry In English from Sir Philip Sidney to the present day, wading through the remarkable sludge of silliness that characterises them: bad history, wish fulfillment, ludicrous claims, a willful refusal to deal with poetry as the sum total of poems, poets as the people who produce them or the world as it is. Why this nonsense has ever been given credence is a fascinating question in itself.. So it's great to see we have a national body to support poetry in Australia, but why does it have to open with a claim like this:. Australian Poetry’s vision is to excite all Australians about Australian poetry and poets. ALL Australians?.....name anything that excites All Australians.. Monday, February 21, 2011

text: A miniaturised scanner that can peer into the brains of freely-roaming rats has been demonstrated by researchers.. Their wearable “Ratcap” does positron emission tomography – an established technique that tracks the movement and change of an injected molecule.. Typically these scans must be done on anaesthetised rats in a fixed scanner.. The device, Nature Methods, will allow researchers to study them in detail as they move, acquiring both chemical and behavioural information.. Positron emission tomography, or PET, measures the brief flashes of high-energy light that result from the radioactive decay of a “tracer” molecule.

Title: Understanding Positron Emission Tomography (PET) in Neuroscience Research

## Lesson Overview
In this lesson, we will learn about Positron Emission Tomography (PET), a powerful imaging technique used in neuroscience research. We will explore how PET works, its applications in studying rat behavior, and how the Ratcap device is revolutionizing the field of neuroscience.

## Section 1: Introduction to PET
### Question: What is PET and what does it do?
Answer: PET is a non-invasive imaging technique that uses radioactive tracers to visualize and measure the metabolic processes within the body. It is commonly used in medical diagnosis and research to study the function of organs and tissues. In neuroscience research, PET is used to study the brain's activity and function.

### Question: How does PET work?
Answer: PET works by injecting a small amount of a radioactive tracer into the subject's bloodstream. The tracer is designed to target specific molecules or receptors within the body, allowing researchers to track the movement and change of the tracer as it interacts with the target. When the tracer decays, it emits a positron, which then annihilates an electron nearby. This annihilation event produces two gamma rays, which are detected by a ring of detectors surrounding the subject. By analyzing the data collected by the detectors, researchers can create a three-dimensional image of the tracer's distribution within the body.

### Question: What are some applications of PET in neuroscience research?
Answer: PET is widely used in neuroscience research to study brain function, metabolism, and blood flow. It can be used to investigate the effects of drugs on the brain, to map the distribution of neurotransmitters and other molecules, and to study the progression of neurological disorders such as Alzheimer's disease and Parkinson's disease.

## Section 2: The Ratcap Device and its Applications
### Question: What is the Ratcap device and how does it work?
Answer: The Ratcap device is a miniaturized PET scanner that can be worn by rats as they move freely. It was developed by researchers at the University of California, Los Angeles, to enable the study of rat behavior in a natural environment while simultaneously acquiring chemical and behavioral information. The Ratcap device consists of a helmet-like scanner that contains detectors and a computer to process the data. The rat wears a harness with a custom-made pillow to hold the helmet in place.

### Question: What are some applications of the Ratcap device in neuroscience research?
Answer: The Ratcap device has several applications in neuroscience research, including:
- Studying the effects of drugs on rat behavior and brain function in a natural environment
- Investigating the neural mechanisms underlying complex behaviors such as learning and memory
- Mapping the distribution of neurotransmitters and other molecules in the rat brain during natural behavior
- Studying the progression of neurological disorders in rats, such as epilepsy and addiction

## Section 3: Practical Examples and Real-World Scenarios
### Question: Can you provide an example of how the Ratcap device might be used in a neuroscience experiment?
Answer: Sure! Let's say a researcher wants to study the effects of a new drug on rat behavior and brain function. They could administer the drug to a group of rats and monitor their behavior using video recordings. At the same time, they would use the Ratcap device to scan the rats' brains and measure changes in neurotransmitter levels and blood flow. By comparing the behavioral data with the PET scan data, the researcher could determine whether the drug had any effect on the rats' brain function and, if so, which areas of the brain were affected.

### Question: How might the Ratcap device be used to study the progression of a neurological disorder in rats?
Answer: The Ratcap device could be used to study the progression of a neurological disorder such as epilepsy in rats. By scanning the brains of rats with the disorder at different stages of progression, researchers could identify changes in neurotransmitter levels and brain activity that correspond to the onset and worsening of symptoms. This information could help researchers develop new treatments for the disorder and improve our understanding of its underlying causes.

## Glossary
- Positron Emission Tomography (PET): A non-invasive imaging technique that uses radioactive tracers to visualize and measure the metabolic processes within the body.
- Ratcap device: A miniaturized PET scanner that can be worn by rats as they move freely.
- Neurotransmitters: Chemical messengers that transmit signals across a synapse between neurons.
