text: Wavelength and mass resolved resonance-enhanced two photon ionization (R2PI) excitation spectra of (R)-(+)-1-phenyl-1-propanol (P-R) and its complexes with some chiral esters, i.e. methyl lactates (L-R and L-S), methyl 3-hydroxybutyrates (H-R and H-S), and methyl 2-chloropropionates (C-R and C-S), have been recorded after a supersonic molecular beam expansion and interpreted in the light of DFT calculations. The spectral features of the selected complexes were found to depend on the nature of hydrogen-bond interactions within the diasteromeric complexes, whose intensity in turn depends upon the structure and the configuration of the estereal moiety. The study further confirms resonant two-photon ionization spectroscopy, coupled with time-of-flight mass resolution (R2PI-TOF), as an excellent tool for gathering valuable information on the interactive forces in molecular clusters and for the enantiodiscrimination of chiral molecules in the gas phase.

Lesson: Understanding Spectroscopy and its Application in Chiral Molecules Identification

Introduction:
Spectroscopy is a technique used to study the interaction of matter and electromagnetic radiation. In this lesson, we will learn about Resonance-Enhanced Two Photon Ionization (R2PI) spectroscopy and its application in identifying chiral molecules.

Section 1: Understanding R2PI Spectroscopy

Topic 1: What is R2PI Spectroscopy?
R2PI spectroscopy is a nonlinear spectroscopic technique that involves the excitation of molecules using two photons instead of one. This technique is particularly useful for studying chiral molecules, which are molecules that are mirror images of each other but have different properties.

Topic 2: How does R2PI work?
In R2PI spectroscopy, a molecule is first excited by a single photon, which causes it to enter an excited state. A second photon is then used to promote the molecule to a higher energy state, resulting in the ionization of the molecule. By analyzing the energy and momentum of the ionized molecule, scientists can gain valuable information about the molecule's structure and properties.

Topic 3: Why is R2PI useful for studying chiral molecules?
Chiral molecules often have very similar spectra, making it difficult to distinguish between them using traditional spectroscopic techniques. However, R2PI spectroscopy can provide unique spectral features that allow for the identification and differentiation of chiral molecules.

Section 2: Applying R2PI Spectroscopy to Chiral Molecules

Topic 1: What is the role of hydrogen bonding in chiral molecules?
Hydrogen bonding plays a crucial role in the structure and properties of chiral molecules. The strength and direction of hydrogen bonds can determine the configuration of a chiral molecule, which in turn affects its properties such as solubility, reactivity, and biological activity.

Topic 2: How do R2PI spectra vary depending on the nature of hydrogen bonding?
The spectral features of chiral molecules in R2PI spectra are influenced by the nature of hydrogen bonding within the molecule. For example, the intensity of the spectral features may depend on the strength and direction of hydrogen bonds, as well as the structure and configuration of the estereal moiety.

Topic 3: What information can be gathered from R2PI spectra of chiral molecules?
By analyzing R2PI spectra of chiral molecules, scientists can gain valuable information about the interactive forces in molecular clusters and the enantiodiscrimination of chiral molecules in the gas phase. This information can be used to better understand the structure and properties of chiral molecules and their potential applications in various fields such as pharmaceuticals, materials science, and environmental chemistry.

Conclusion:
In this lesson, we have learned about R2PI spectroscopy and its application in studying chiral molecules. We discussed the principles of R2PI spectroscopy, its advantages for studying chiral molecules, and how hydrogen bonding influences the spectral features of chiral molecules. By understanding these concepts, we can gain valuable insights into the structure and properties of chiral molecules and their potential applications in various fields.

In this lesson, we will learn about the sleep behaviors in adolescents and young adults with ASD and how they are associated with daytime behavior.

Section 1: Understanding Sleep Behaviors in Autistic Individuals

Topic 1: Sleep Problems in Autistic Individuals
- Autistic individuals often have difficulty falling asleep, staying asleep, and waking up too early.
- These sleep problems can lead to daytime behavior issues such as irritability, aggression, and social difficulties.

Topic 2: Types of Sleep Behaviors in Autistic Individuals
- Insomnia: Difficulty falling or staying asleep, even when there is enough time in bed.
- Sleep apnea: Breathing problems during sleep that can cause snoring, choking, or gasping for air.
- Restless legs syndrome: An urge to move one's legs due to uncomfortable sensations, often accompanied by creeping, crawling, or tingling feelings.
- Night terrors: Sudden, violent movements during sleep that can cause injury to oneself or others.

Topic 3: Causes of Sleep Behaviors in Autistic Individuals
- Sensory sensitivities: Over-responsivity or under-responsivity to sounds, lights, touch, and other sensory information can make it difficult for autistic individuals to fall asleep.
- Anxiety and stress: Autistic individuals may have heightened anxiety and stress levels, which can interfere with their ability to fall asleep.
- Medication side effects: Some medications used to treat ASD symptoms can interfere with sleep.

Section 2: Determining the Association Between Sleep and Daytime Behavior

Topic 1: How Sleep Affects Daytime Behavior
- Poor sleep can lead to irritability, mood swings, and difficulty concentrating during the day.
- Sleep deprivation can also exacerbate other ASD symptoms such as hyperactivity, impulsivity, and social difficulties.

Topic 2: Measuring Sleep Behaviors

Atlas, Facebook's advertising platform, is now open for business following an overhaul from the ground up.

First acquired from Microsoft last year by the social media giant, Atlas was reportedly in the middle of a revamp following Facebook's acquisition. However, it seems the platform has been completely rewritten for use on the social media website, according to a company blog post.

The company said Atlas has been rebuilt "from the ground up" to cater for today's marketing needs, such as "reaching people across devices and bridging the gap between online impressions and offline purchases."

"Atlas delivers people-based marketing, helping marketers reach real people across devices, platforms and publishers," Atlas says. "By doing this, marketers can easily solve the cross-device problem through targeting, serving and measuring across devices. And, Atlas can now connect online campaigns to actual offline sales, ultimately proving the real impact that digital campaigns have in driving incremental reach and new sales."

Advertisers often have to rely on cookies to track advert interactions, and as people spend more time than ever on their devices -- shopping, comparing and researching -- mobility had led to a shift in consumer behavior and purchase decisions. While 10 years ago you may have stayed local when shopping, for example, the Internet has led to increased competition and wider consumer choice.

The problem is closing the gap between devices and purchase decisions -- as cookies do not work well on mobile. As a result, demographics, data collection, advert targeting and measuring have all become less accurate than before. This leaves marketers at a disadvantage in a changing commercial world.

In order to solve this issue, Facebook wants to use what Atlas calls "people-based marketing." According to reports , the social media giant will be able to use Atlas' new code base to 'anonymously' track individuals across a range of devices. As an example, a purchase made on a PC could be traced back to an ad impression from a smartphone or tablet.

In addition, adverts generated from Atlas partners can be tailored across other websites depending on the data Facebook has on a group of users -- such as age, sex and location.

Atlas head Erik Johnson says:

"Atlas has been rebuilt on an entirely new code base, with a user interface designed for today’s busy media planners and traffickers. Targeting and measurement capabilities are built-in, and cross-device marketing is easy with new ways of evaluating media performance centered on people for reporting and measurement. This valuable data can lead to better optimization decisions to make your media budget even more effective."

The first company to sign up with Atlas is Omnicom. The company and Atlas will jointly develop integrative systems for Omnicom's clients, which include Intel and Pepsi, in order to test the new platform. Atlas says that other partners are swiftly coming on board, and Instagram -- as a publisher -- is now enabled with Atlas to both measure and verify ad impressions.

How To Create the LOVE LIFE You Truly Desire

How To Create the LOVE LIFE You Truly Desire

My insatiable desire to seek knowledge for the truth about life and love began in 2008. These questions I had lead me on a journey of self-discovery that opened my eyes to a whole new perspective on myself, men, relationships, love and life. After going through the highs and lows, and everywhere in between, I finally got to a place where I wanted to know how I could live a stress free life. I wanted to break the destructive behaviors/cycles that no longer served me especially when it came to relationships. With the help of empowerment books, seminars, webinars, love coaches, documentaries about universal energies of oneness, laws of attraction and countless hours of self-reflection in meditation, I finally started learning what it meant to love myself and others UNCONDITIONALLY.

In discovering this and my true purpose in life, I began to experience a new found freedom. I had a new appreciation for life and the world we live in. It all starts with learning to love yourself, as cliche as it sounds it’s true. Below are some of the realizations I crossed on my truth journey.

LEARNING TO LOVE YOURSELF

Most people only understand that on a surface level. I’m talking about loving yourself on a deeper, soulful level. Sadly, we are all a product of our pain and insecurities and as long as we allow those fearful emotions to consume us, and let them dictate our choices, we are not fully loving ourselves or others. When we continue to experience the same problems in relationships, or are stuck in a cycle of unhealthy behaviors there is something at a much deeper level that must be uncovered. You have to find the root that causes these destructive thinking patterns, then change your way of thinking.

RESPONDING VS. REACTING

Learning how to process emotions in a constructive manner vs. destructive can have a significant impact on the quality of your relationships. There is a big difference when you learn how to RESPOND VS. REACT in high stress situations.

Instead of complaining about your love life put that energy into learning how to do something entirely new and create the love life you’ve always desired. Most are fearful to tread these waters, but this is how you GROW!! Constructive thinking is a way of being mindful and getting to this place doesn’t just magically happen. It is a new way of thinking that has to be learned and practiced over time.

Achieving internal peace can be experienced if we can learn how to remain poised regardless of what life throws our way. Unfortunately we are not wired to be poised. We are quick to get upset when things don’t go our way. We instantly go into REACT MODE. We blame, criticize, judge, make negative assumptions and feel sorry for ourselves… ALL OF THIS STUFF creates a lot of internal disturbance. It interferes with your ability to see from a broader perspective which is what is necessary if you want to reach your full potential.

SHEDDING THE VICTIM MENTALITY

People are accustomed to being in a reactive mode. We tend to look externally at the person or situation that is “pushing our buttons”. When a negative emotion gets triggered it causes “the victim” chatter: “why me?”, “why is this happening?”, “why are they doing this to me?”, etc. Instead we need to learn how to get centered, look internally, and ask the RIGHT questions to find out why we have these buttons in the first place. This is the CREATOR mentality. Choosing not to fall prey to the victim mentality is part of the waking up process, and it is very liberating. There are tools you’ll need to help you achieve this mindset. Not only will these be helpful when you have conflict with your partner but co-workers, friends and family as well.

ACCEPTING RESPONSIBILITY FOR THE QUALITY OF YOUR LIFE

This is an important step in this journey. It’s a humbling experience, one everyone could benefit from. Fully understanding how and why the choices you make play a vital role in the creation of your life is powerful stuff. This is when you start to recognize you really are a co-creator in the story of your life. Your thoughts, beliefs, ideas and decisions create your reality. How healthy, loving and positive are they? Becoming aware of how much fear and negativity consumes you on a daily basis is an eye opener.

TAKING INVENTORY OF YOUR THOUGHTS

Start taking inventory of your thoughts, your intentions, the company you surround yourself with and your daily verbal and non-verbal interactions with people. Because the truth is they all play a part in creating your world. Your perception of the world (which YOU are creating every moment of everyday) becomes your truth. Let that soak in for minute. What kind of world have you created for yourself? Is it mostly peaceful and joyful or does life feel like a constant struggle? What are most of your relationships like…do they drain you and bring you down or lift and inspire you? Do you constantly judge and criticize yourself and others?

Ask yourself, “what areas in my life are creating the most stress?” This is where a mindfulness coach come in handy. I help you design a personal action plan to help you overcome the obstacles and challenges you are facing. I am sharing what I learned with others through my S.A.F.E. Self-Discovery steps. It’s difficult to go through this transformation alone, everyone needs help in life especially when you are making big changes.

Get the positive guidance and support you need to help you stay on track. Even though a support system is important, it’s ultimately up to you to MAKE THE CHOICE to want a better life for yourself. Learning how to “BE LOVE” is one of the greatest most significant gifts you can give yourself and to others. When you learn to come from a place of LOVE and COMPASSION you can live in a state of PEACE and HAPPINESS.

POSITIVITY FUELS YOU

Energetically speaking, negativity eats up way more energy. Negativity depletes you and positivity FUELS YOU! The less energy you have the more susceptible your immune system becomes. Science has proven that a positive attitude is directly connected to human happiness and health. So for you “glass half empty” “Debbie downer” readers, do your mind and body good and learn how to flip the script. When you begin to do this inner reflection and self-work you feel more emotionally balanced.

LEARNING TO LET GO

Other principles that aide in maintaining emotional stability is learning to be honest with yourself and others, letting go of expectations, not assuming, not taking things personal… these are all things we do on a daily basis and all of them create mental, emotional and physical disturbance. Holding on to hurt, anger, sadness, resentment and guilt doesn’t serve you either. Learning to let it go and detach from it is part of learning about love.

GRATITUDE

Living life in this manner makes it easier to focus on gratefulness. Gratitude alone can change your life. We should look at “unexpected challenges/tragedies” in life as opportunities to learn something deeper about ourselves. We tend to only be grateful when life is going well, but when you can find gratitude even in the dark moments of life something beautiful starts to emerge from within. This awakening and transformation has been challenging (change always is), but it has also been very rewarding. If this blog has spoken to you, then maybe it’s time for a change. Like Ghandi said, “Be the change you want to see in the world.” It’s time you create a happier, brighter more peaceful world for yourself.

Lesson: How to Love Yourself Unconditionally

Introduction

Loving yourself unconditionally is one of the most important things you can do for your mental and emotional well-being. When you love yourself, you become confident, happy, and at peace with who you are. In this lesson, we will explore what it means to love yourself unconditionally, why it's important, and how you can start loving yourself today.

What does it mean to love yourself unconditionally?

Loving yourself unconditionally means accepting and appreciating yourself just the way you are, flaws and all. It means being kind to yourself, treating yourself with respect, and taking care of your physical, emotional, and mental needs. When you love yourself unconditionally, you don't judge yourself harshly or beat yourself up over mistakes. Instead, you learn from your mistakes and move forward with grace and compassion.

Why is it important to love yourself unconditionally?

Loving yourself unconditionally is important because it sets the foundation for all other relationships in your life. When you love yourself, you become confident and secure in your own skin. This confidence attracts healthy, positive people into your life and repels negative ones. Additionally, loving yourself unconditionally allows you to give and receive love more freely and authentically.

How can I start loving myself unconditionally?

1. Practice self-compassion: Start by being kind to yourself. Treat yourself the way you would treat a good friend. Be gentle with yourself and avoid self-criticism.

2. Accept yourself: Accept your flaws, quirks, and imperfections. Remember that everyone has them, and they are what make us unique.

3. Celebrate your accomplishments: Take time to celebrate your achievements, no matter how small they may seem. Recognize and appreciate your strengths and accomplishments.

4. Set boundaries: Learn to say "no" when you need to and set boundaries that protect your time, energy, and well-being.

5. Take care of yourself: Make time for self-care activities such as exercise, meditation, and relaxation. Eat healthily, get enough sleep, and engage in activities that bring you joy.

Conclusion

Loving yourself unconditionally is a journey, not a destination. It takes time, patience, and practice to develop a healthy sense of self-love. But the rewards are worth it - a happier, more fulfilling life filled with love, compassion, and understanding.

Lesson Title: The Science of Waves

Introduction:
Waves are everywhere. They are in the ocean, on land, and even in the air. In this lesson, we will learn about the science of waves, including what they are, how they travel, and how they can be measured. We will also explore the different types of waves and their properties.

Section 1: What are Waves?

A wave is a disturbance that transfers energy from one place to another without transferring matter. It is created when something vibrates or moves back and forth. Waves can travel through different materials, like air, water, and glass.

Activity: Try to create your own wave by clapping your hands. You can also try to create a wave in a puddle of water.

Section 2: How do Waves Travel?

Waves travel through a medium, like air or water. They move energy from one place to another without moving the matter itself. When a wave travels through a medium, it causes the particles in the medium to vibrate. This is called wave propagation.

Activity: Try to make a wave in a Slinky toy. You can also try to make a wave in a string.

Section 3: Measuring Waves

Waves can be measured in several ways. One way is to measure the distance between the crest (the top) and the trough (the bottom) of the wave. Another way is to measure the height of the wave from the still water level to the top of the wave.

Activity: Measure the height of a book with a ruler. How does this compare to the height of a wave?

Section 4: Types of Waves

There are two main types of waves: transverse waves and longitudinal waves. Transverse waves move perpendicular to the direction of the wave's energy transfer, while longitudinal waves move parallel to the direction of the wave's energy transfer.

Activity: Try to draw a picture of a transverse wave and a longitudinal wave.

Section 5: Properties of Waves

There are several properties of waves that scientists study. These include frequency, amplitude, wavelength, and speed. Frequency is the number of waves that pass a certain point in a given time period. Amplitude is the maximum displacement of a particle in a wave from its rest position. Wavelength is the distance between two consecutive points that are the same in the wave. Speed is how fast the wave travels.

Activity: Try to measure the frequency, amplitude, wavelength, and speed of a wave using a ruler and a stopwatch.

Conclusion:
In this lesson, we learned about the science of waves. We learned that waves are disturbances that transfer energy without transferring matter. We also learned that waves travel through a medium and cause the particles in the medium to vibrate. Finally, we explored the different types of waves and their properties. By understanding these concepts, we can better appreciate the power and beauty of waves in our world.

Lesson: Rocket Engines

## Section 1: Introduction

Rocket engines are used to propel rockets into space. They work by burning fuel and producing hot gas that pushes the rocket forward. In this lesson, we will learn about the different types of rocket engines, how they work, and their applications.

## Section 2: Types of Rocket Engines

There are two main types of rocket engines: liquid fuel engines and solid fuel engines.

1. Liquid fuel engines: These engines use liquid fuel and oxidizer (a substance that helps burn the fuel) to produce thrust. The most common type of liquid fuel engine is the kerosene-based rocket engine.

2. Solid fuel engines: These engines use solid fuel that is mixed with an oxidizer to produce thrust. The most common type of solid fuel engine is the solid rocket booster, which is used to launch spacecraft into orbit.

## Section 3: How Rocket Engines Work

Rocket engines work by burning fuel and producing hot gas that pushes the rocket forward. The basic principle behind a rocket engine is Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. This means that when a rocket engine produces thrust, it also propels itself forward.

1. Intake of air: As the rocket engine accelerates, it needs more oxygen to burn the fuel. So, it takes in air from the surrounding atmosphere or from a supply on board the rocket.

2. Combustion: The fuel and oxidizer are mixed together in the combustion chamber, where they are ignited. This produces hot gas, which is forced out of the back of the engine.

3. Exhaust: The hot gas produced in the combustion chamber is expelled out of the back of the engine, creating thrust. This thrust propels the rocket forward.

4. Thrust: The force generated by the exhaust gases pushing against the air is what propels the rocket forward. This force is called thrust, and it is measured in pounds or newtons.

## Section 4: Applications of Rocket Engines

Rocket engines are used in a variety of applications, including launching satellites into orbit, sending astronauts to the International Space Station, and exploring other planets in our solar system. Here are some examples of how rocket engines are used:

1. Launch vehicles: Rocket engines are used to launch satellites and spacecraft into orbit. The most famous example of this is the Space Shuttle, which used solid rocket boosters to lift off from the launch pad.

2. Manned spacecraft: Rocket engines are also used to power manned spacecraft, such as the Soyuz spacecraft used to send astronauts to the International Space Station.

3. Unmanned spacecraft: Rocket engines are used to power unmanned spacecraft, such as the Mars rovers and the Voyager probes that have explored the outer planets.

4. Satellites: Rocket engines are used to launch communication satellites, weather satellites, and other types of satellites into orbit around the Earth.

## Section 5: Conclusion

In this lesson, we learned about the different types of rocket engines, how they work, and their applications. Rocket engines are essential for space exploration and travel, and they have allowed us to explore the far reaches of our solar system and beyond. By understanding the principles behind rocket engines, we can continue to push the boundaries of what is possible in space exploration and travel.

Treatment of HNSCC cell lines with the EGFR-specific inhibitor cetuximab (Erbitux) results in paradox phosphorylation of tyrosine 1173 in the receptor.
Overexpression of the epidermal growth factor receptor (EGFR, ErbB1, HER1) is frequent in head and neck squamous cell carcinomas (HNSCCs) and correlates with disease progression. Inhibition of EGFR with the kinase inhibitor AG1478 abolished receptor phosphorylation and reduced cell proliferation. However, treatment of HNSCC cells with cetuximab (Erbitux), a monoclonal antibody designed to block the EGFR ligand binding site, led to paradox EGFR activation due to hyperphosphorylation of tyrosine 1173, however, with a concomitant reduction in Erk1/2 phosphorylation levels. No pronounced influence on cell proliferation levels could be observed after treatment with this antibody. Since cetuximab appears able to activate EGFR in HNSCC cell lines, it is necessary to rethink the exact mechanisms by which cetuximab that recently was approved for the treatment of advanced head and neck cancer, inhibits tumor growth.

Lesson: Understanding EGFR Signaling Pathway in Cancer Cells

Introduction:
The epidermal growth factor receptor (EGFR) is a protein that plays a crucial role in cell growth and division. Abnormal activation of the EGFR signaling pathway has been implicated in various types of cancer, including head and neck squamous cell carcinomas (HNSCCs). In this lesson, we will explore the EGFR signaling pathway and its role in cancer cells.

Section 1: EGFR Signaling Pathway

The EGFR signaling pathway is a series of molecular events that lead to the activation of the EGFR protein. When the EGFR binds to its ligand (a signaling molecule), it triggers a cascade of events that ultimately leads to the activation of other proteins, such as the mitogen-activated protein kinase (MAPK) pathway. This activation can result in increased cell growth and division.

Questions:
1. What is the EGFR signaling pathway?
2. How does the activation of the EGFR signaling pathway contribute to cancer cell growth?

Section 2: Targeting the EGFR in Cancer Treatment

One approach to treating cancer is to target the proteins or pathways that are involved in cancer cell growth. One such target is the EGFR. Several drugs have been developed to specifically block the activation of the EGFR, such as the tyrosine kinase inhibitors (TKIs) gefitinib and erlotinib. Another approach is to use monoclonal antibodies, such as cetuximab, which bind to the extracellular domain of the EGFR and prevent it from interacting with its ligand.

Questions:
3. Why is targeting the EGFR an effective strategy for cancer treatment?
4. What are some examples of drugs that target the EGFR?

Section 3: Paradox Phosphorylation and Cetuximab

Recent studies have shown that treatment of HNSCC cells with cetuximab can lead to paradox EGFR activation due to hyperphosphorylation of tyrosine 1173. This activation occurs despite the presence of the cetuximab molecule, which should block the ligand binding site. This phenomenon, known as paradox phosphorylation, has been observed in other cancer cell types as well.

Questions:
5. What is paradox phosphorylation?
6. Why does cetuximab appear to activate EGFR in some cancer cells?

Conclusion:
Understanding the EGFR signaling pathway and its role in cancer cell growth is essential for developing targeted therapies. While targeting the EGFR has shown promise in treating certain types of cancer, the paradox phosphorylation observed in some cancer cells highlights the complexity of this pathway. Further research is needed to fully understand the mechanisms behind cetuximab-induced EGFR activation and to develop more effective cancer treatments.

Q:

How to set the corner radius of a UIContextualAction?

I haven't found anything on how to do this so I am asking a question.
I made a cell with three actions:

A check action,
an edit action,
and a delete action.

The only problem is that my cell has a corner radius to it and I want my actions to also have a corner radius. How do I set the corner radius of a UIContextualAction?
Is this even possible?

A:

Because UIContextualAction inherits from NSObject, there's no layer to draw or adjust. You'll have to build your own utility underlay view and swipe gesture, or use something like SwipeCellKit which supports custom styled contextual actions.

textbook:
Lesson: How to Set the Corner Radius of a UIContextualAction

Introduction:
In this lesson, we will learn how to set the corner radius of a UIContextualAction. We will start by understanding what UIContextualAction is and why it is used. Then, we will explore different ways to achieve the desired corner radius effect. Finally, we will conclude by applying the learned skills to new problems.

What is UIContextualAction?
UIContextualAction is a class that provides a way to display contextual actions in an iOS application. It is usually used to show actions when the user long-presses or right-clicks on an element in the app.

Why do we need to set the corner radius of a UIContextualAction?
The corner radius of a UIContextualAction is important because it adds a rounded border to the action, making it look more visually appealing and professional. It also helps to differentiate the action from other elements in the app.

How can we set the corner radius of a UIContextualAction?
There are several ways to set the corner radius of a UIContextualAction:

1. Using the `UIBezierPath` class: You can create a `UIBezierPath` object and add a rounded rectangle to it. Then, you can set the `path` property of the UIContextualAction to the `UIBezierPath` object.
2. Using CALayer: You can create a `CAShapeLayer` object and add a rectangle to it. Then, you can set the `cornerRadius` property of the `CAShapeLayer` object to the desired value. Finally, you can add the `CAShapeLayer` object to the `layer` property of the UIContextualAction.
3. Using third-party libraries: There are several third-party libraries available that provide pre-built UIContextualAction classes with built-in corner radius support. Some popular libraries include SnapKit, Kingfisher, and RxSwift.

Conclusion:
In this lesson, we learned how to set the corner radius of a UIContextualAction using different methods. We also explored why it is important and how it can be achieved using various techniques. By understanding these concepts, we can apply them to new problems and create visually appealing and professional UIContextualActions.

Lesson: Introduction to WebSockets

## Section 1: What are WebSockets?
WebSockets are a type of network protocol that allows for real-time, bi-directional communication between a client and a server. They are useful for applications that require a persistent connection between the user and the server, such as online games, chat rooms, and real-time analytics.

## Section 2: How do WebSockets work?
WebSockets work by establishing a persistent connection between a client and a server. When a client sends a message to the server, the server responds immediately without the need for the client to send another request. This makes WebSockets more efficient than other methods of communication, such as polling or long-polling, which require the client to send multiple requests to the server.

## Section 3: Why use WebSockets?
WebSockets are useful for real-time applications because they allow for fast, reliable communication between the client and the server. They also reduce the amount of traffic on the network, making them more efficient than other methods of communication.

## Section 4: Examples of WebSocket usage
WebSockets can be used in a variety of applications, including:
- Online games: WebSockets allow for real-time game updates and player interactions.
- Chat rooms: WebSockets enable users to send and receive messages instantly, without the need for multiple requests.
- Real-time analytics: WebSockets provide real-time data updates, allowing users to make informed decisions based on current information.

## Conclusion
WebSockets are an important tool for real-time communication between clients and servers. By establishing a persistent connection, WebSockets allow for fast, reliable communication that is essential for many modern applications. By understanding how WebSockets work and why they are useful, developers can create more efficient and effective real-time applications.

Lesson: Understanding Craft Beer Industry Growth

Introduction:
Craft beer has been growing in popularity over the past few years. In this lesson, we will explore the factors driving this growth and how it compares to the larger beer industry. We will also look at some of the challenges that craft brewers face and how they are overcoming them.

Section 1: Understanding the Craft Beer Industry

Topic 1: What is Craft Beer?
Craft beer is a type of beer that is produced by small, independent brewers. These brewers use traditional brewing methods and often focus on creating unique flavors and styles of beer. Craft beer is typically made in small batches and is often sold in draft form.

Topic 2: Growth of the Craft Beer Industry
The craft beer industry has been growing rapidly over the past few years. In 2012, craft beer sales grew by 12%, compared to just 2% growth for the overall beer industry. This growth is due to several factors, including an increased interest in unique and flavorful beers, a desire for locally-made products, and a shift away from mass-produced, generic beers.

Section 2: Comparing Craft Beer to the Overall Beer Industry

Topic 1: Market Share
Unlike the overall beer industry, which is dominated by a few large companies like Anheuser-Busch and MillerCoors, craft beer is much more fragmented. More than three-quarters of the craft beer segment is split among 2,000 smaller rivals. This means that there are many more players in the craft beer industry, but each one has a much smaller share of the market.

Topic 2: Shipment Trends
While the overall beer industry has seen declining shipments in recent years, craft beer has been experiencing significant growth. In 2011, craft beer shipments grew by 13%, while overall beer shipments fell by 1%. This trend continued in 2012, with craft beer shipments increasing by 12%, while overall beer shipments fell by 2%.

Section 3: Challenges and Opportunities for Craft Brewers

Topic 1: Distribution
One of the biggest challenges that craft brewers face is distribution. Unlike larger brewers, who can afford to invest in expensive distribution networks, craft brewers often have to rely on smaller distributors who may not be able to reach as many customers. This means that craft brewers may have difficulty getting their beer into stores and restaurants, which can limit their growth potential.

Topic 2: Marketing
Another challenge that craft brewers face is marketing. While larger brewers have massive budgets to spend on advertising, craft brewers often have to rely on word-of-mouth and social media to promote their products. However, this also presents an opportunity for craft brewers to connect with their customers on a personal level and create a strong brand identity.

Conclusion:
In conclusion, the craft beer industry has been experiencing significant growth in recent years, due in part to an increased interest in unique and flavorful beers, a desire for locally-made products, and a shift away from mass-produced, generic beers. While the overall beer industry is dominated by a few large companies, the craft beer industry is much more fragmented, with many smaller brewers vying for market share. However, craft brewers still face challenges such as distribution and marketing. By focusing on building strong relationships with customers and creating unique, high-quality products, craft brewers can continue to thrive in a competitive industry.

Hypertension in Thai children: a report from a hospital in suburban area.
Hypertension in children is the major risk for cardiovascular disease in adult. Limited data are available for hypertension in children in Southeast Asia. To determine the cause, treatment, and long-term outcome of hypertension in Thai Children, the authors retrospectively studied 62 patients (age <15 years) diagnosed with hypertension at Thammasat University hospital, from December 01, 2004 through November 30, 2009. The mean age was 9.2 +/- 4.2 years; median follow-up 8 months. Fifty five (88.7%) patients had secondary hypertension. Patients presented with stage 2 hypertension (67.7%), and hypertensive emergency (9.7%). Renal parenchymal disease caused 67.3% of secondary hypertension. End organ damage included left ventricular hypertrophy (11.3%) and hypertensive retinopathy (6.4%). Hypertensive emergency was caused mostly by acute poststreptococcal glmoerulnephritis (APSGN, 66.7%). Intravenous diuretic coupled with oral antihypertensive drugs gave uncontrolled blood pressure in APSGN with hypertensive emergency. Seventy percents of patients with essential hypertension had obesity. Majority of the patients had controlled hypertension without medication. Acute poststreptococcal glomerulonephritis remained the common cause of transient hypertension and hypertensive emergency in Thai children. The high incidence of obesity among essential hypertension in children demonstrated in the present study should alert Thai pediatrician to measure blood pressure in every obese child. Treatment of childhood hypertension was associated with good long-term outcome.

Lesson: Introduction to Hypertension in Children
Hypertension, or high blood pressure, is a serious medical condition that can lead to severe health complications if left untreated. In this lesson, we will learn about hypertension in children, including its causes, symptoms, and treatment options.
Section 1: What is Hypertension?
Hypertension is a medical condition characterized by abnormally high blood pressure. It is usually measured in millimeters of mercury (mmHg) and is recorded as two numbers, such as 120/80 mmHg. The first number represents the systolic blood pressure, which is the pressure in the arteries when the heart beats, while the second number represents the diastolic blood pressure, which is the pressure in the arteries when the heart is at rest.
Section 2: Causes of Hypertension in Children
There are several factors that can contribute to hypertension in children, including genetic factors, lifestyle choices, and underlying medical conditions. Some common causes of hypertension in children include:
- Genetic factors: Hypertension can run in families, and children who have parents or siblings with high blood pressure are at a higher risk of developing the condition.
- Lifestyle choices: A sedentary lifestyle, poor diet, and lack of physical activity can all contribute to hypertension in children.
- Underlying medical conditions: Some medical conditions, such as kidney disease or hormonal imbalances, can cause hypertension in children.
Section 3: Symptoms of Hypertension in Children
In many cases, hypertension in children does not cause any noticeable symptoms. However, when symptoms do occur, they may include:
- Headaches
- Dizziness
- Nausea
- Fatigue
- Irritability
- Frequent urination
Section 4: Treatment Options for Hypertension in Children
Treatment for hypertension in children depends on the underlying cause and severity of the condition. Some common treatment options include:
- Lifestyle changes: A healthy diet, regular exercise, and reducing salt intake can help lower blood pressure in children with hypertension.
- Medication: In some cases, children with hypertension may need to take medication to help control their blood pressure.
- Monitoring: Regular check-ups with a healthcare provider are important for monitoring blood pressure and adjusting treatment as needed.
Section 5: Conclusion
Hypertension in children is a serious medical condition that requires prompt attention and treatment. By understanding the causes, symptoms, and treatment options for hypertension in children, we can help ensure that children receive the care they need to manage their condition and lead healthy lives.

text: Some”. Benefits. Every programmer’s goal is to maximise productivity while minimising the amount of effort expended.. Without diving into the history of bash and Z shell, let’s talk about some wins I have experienced in my workflow:. cd tab autocomplete. For bash, the tab autocomplete shows a list of directories matching the current word, while Z shell allows me to cycle through the directory list with a double tab.. It is not a big deal when there is only one directory that matches the current word, but can save a tiny bit of time when there are multiple matches and the names are long.

Lesson: Using Tab Completion in Command Line Interfaces (CLI)

## Introduction
In this lesson, we will learn about the benefits of using tab completion in command line interfaces (CLI). We will explore the differences between bash and Z shell and their respective tab completion features. Finally, we will discuss how to use tab completion to improve productivity and efficiency in our coding workflow.

## Section 1: Theory
- Tab completion is a feature in many command line interfaces (CLI) that allows users to complete commands by typing part of the command and then pressing the tab key to automatically complete the rest of the command.
- Bash is a widely used command line shell that provides tab completion for directories and filenames.
- Z shell is another popular command line shell that provides more advanced tab completion features, including cycling through directory listings with a double tap of the tab key.

## Section 2: Practice
- Open your terminal or command prompt and navigate to a directory with multiple files or subdirectories.
- Start typing the name of a file or directory and then press the tab key to see how the autocompletion works.
- Try using the up and down arrow keys to move through the list of suggestions.
- Use the double tap of the tab key to cycle through the directory listings in Z shell.

## Section 3: Examples
- Let's say you are working on a project with multiple files and directories. You want to switch to a specific directory, but you don't want to type out the full path every time. With tab completion, you can simply start typing the name of the directory and press tab to automatically complete the rest of the path.
- Similarly, if you are running a command that requires a file or directory, you can start typing the name and press tab to automatically complete the command. This saves time and reduces the likelihood of typos or errors.

## Glossary
- CLI: Command Line Interface
- Shell: A program that provides an interface for users to interact with an operating system
- Bash: A widely used command line shell
- Z shell: Another popular command line shell with advanced tab completion features

## Conclusion
Using tab completion in CLI can greatly improve productivity and efficiency in our coding workflow. By automating the completion of commands, we can save time and reduce the likelihood of errors or typos. In this lesson, we explored the benefits of using tab completion, the differences between bash and Z shell, and how to use tab completion in practice. We also provided examples of how tab completion can be used to improve our workflow.

Lesson:
Introduction:
In this lesson, we will learn about the importance of privacy and the legal consequences of invading someone's privacy. We will focus on the case of the Duke and Duchess of Cambridge, also known as William and Kate, and their experience with a French celebrity magazine called Closer.
Section 1: Understanding Privacy
Privacy is an essential aspect of human life. It refers to the right of individuals to keep certain aspects of their lives hidden from public view. Privacy is important because it allows people to maintain their dignity and autonomy. Without privacy, people would not feel safe sharing personal information or expressing themselves freely.
Section 2: The Case of William and Kate
In September 2012, William and Kate were pictured relaxing on the terrace of a chateau belonging to the Earl of Snowdon in the southern region of Provence. The photographer used long-lense cameras to capture Kate displaying her breasts while only wearing a skimpy pair of bikini bottoms. Another intimate picture showed William rubbing suncream into his wife's skin.
The publication of these pictures caused a lot of upset and embarrassment to the couple. They considered £1.4million from French Closer magazine appropriate compensation for the damage caused. They also wanted the equivalent of £42,000 from the local newspaper La Provence, which had also published the pictures.
Section 3: Legal Consequences of Invading Privacy
Invading someone's privacy is a serious offense that can have legal consequences. In this case, the French celebrity magazine Closer was ordered to pay £92,000 in damages to the Duke and Duchess of Cambridge for publishing topless photos of Kate Middleton.
In many countries, there are laws that protect people's privacy. These laws prohibit the publication of private information without consent. In some cases, the publication of private information can result in criminal charges.
Section 4: Conclusion
In conclusion, we have learned about the importance of privacy and the legal consequences of invading someone's privacy. We have also looked at the case of William and Kate and the damage caused by the publication of their private pictures. We hope that this lesson has been informative and that you will remember the importance of respecting people's privacy.

Q:

multiple (my and 3rd-party) native libraries in Android NDK

I have to use two native libraries: one is my own and the other one is 3rd-party. As long as I used them in separate projects, everything was ok. But now I'm getting the Exception Ljava/lang/UnsatisfiedLinkError.
I'm using Eclipse.
I found out that if I place the existing library in libs/armeabi, Eclipse begins compilation of the native code and it fails. If I rebuild the JNI part from the command line, compilation succeeds but the 3rd party library disappears. Really stupid.
So how do I tell Eclipse to use an existing .so library along with a library that must be built? The libraries are independent.

A:

The NDK allows for linking with prebuilt user libraries, using the PREBUILT_SHARED_LIBRARY variable.
Assuming that the library you need to link is librandom.so, create a libs folder in jni subfolder of the project folder:
mkdir -p jni/libs
cp librandom.so jni/libs

Then, just create a jni/libs/Android.mk file:
LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE := random
LOCAL_SRC_FILES := librandom.so
include $(PREBUILT_SHARED_LIBRARY)

You can create a section for each prebuilt library, all placed in jni/libs.
Next, you just need to include the above file into your jni/Android.mk to get things to work. In the NDK docs, it is recommended that this be done at the end of the Android.mk, rather than the middle:
include $(LOCAL_PATH)/libs/Android.mk

However, you'll need to do this before the module that requires this library.
For linking, you'll need to add the following into the module section that links to the prebuilt library.
LOCAL_SHARED_LIBRARIES := random

Then when you do ndk-build, it will copy this library into libs/armeabi/ before building the module, and you're good to go.
Note: This does not solve problems with required headers. You'll still need to add the location of the headers for the library into the variable LOCAL_C_INCLUDES in the module that requires it.

A:

This is what I have done for the moment. I will not accept (in stackoverflow sense) my own (this) answer beause it is unsatisfactory.
I have created a new project and copied all java files there. Then, I copied the .so library from the old project and the 3rd party library into libs/armeabi.
That's monstrous. But it works. For the moment. The worst thing is that the version control is torpedoed.

Lesson: Building Native Libraries with the NDK

## Section 1: Introduction

In this lesson, we will learn about building native libraries with the NDK. We will cover the basics of setting up a project, creating a library, and linking it with other libraries. By the end of this lesson, you will be able to build your own native libraries and use them in your Android applications.

## Section 2: Setting Up a Project

The first step in building a native library with the NDK is to set up a project. You can do this by creating a new project in Eclipse or using the command line. Once you have created your project, you will need to add the necessary NDK components to your build.gradle file.

```groovy
dependencies {
    implementation 'com.android.tools.build:gradle:4.1.0'
    implementation "com.github.dcendents:android-maven-gradle-plugin:2.0"
    implementation 'com.google.code.gson:gson:2.8.5'
    implementation 'com.squareup.okhttp3:logging-interceptor:4.9.0'
    implementation 'org.glassfish.jersey:jersey-client:2.27'
    implementation 'org.glassfish.jersey:jersey-common:2.27'
    implementation 'org.glassfish.jersey:jersey-server:2.27'
    implementation 'org.glassfish.jersey:jersey-media-multipart:2.27'
    implementation 'org.glassfish.jersey:jersey-media-moxy:2.27'
    implementation 'org.glassfish.jersey:jersey-client:2.27'
    implementation 'org.glassfish.jersey:jersey-common:2.27'
    implementation 'org.glassfish.jersey:jersey-server:2.27'
    implementation 'org.glassfish.jersey:jersey-media-multipart:2.27'
    implementation 'org.glassfish.jersey:jersey-media-moxy:2.27'
    implementation 'org.glassfish.jersey:jersey-client:2.27'
    implementation 'org.glassfish.jersey:jersey-common:2.27'
    implementation 'org.glassfish.jersey:jersey-server:2.27'
    implementation 'org.glassfish.jersey:jersey-media-multipart:2.27'
    implementation 'org.glassfish.jersey:jersey-media-moxy:2.27'
    implementation 'org.glassfish.jersey:jersey-client:2.27'
    implementation 'org.glassfish.jersey:jersey-common:2.27'
    implementation 'org.glassfish.jersey:jersey-server:2.27'
    implementation 'org.glassfish.jersey:jersey-media-multipart:2.27'
    implementation 'org.glassfish.jersey:jersey-media-moxy:2.27'
}
```

Once you have added the necessary dependencies, you can build your project using the command line or by clicking on "Build Project" in Eclipse.

## Section 3: Creating a Library

The next step in building a native library with the NDK is to create the library itself. You can do this by using the ndk-build command in the jni/libs folder of your project.

```
cd jni/libs
ndk-build
```

This will generate a .so file in the libs/armeabi-v7a folder.

## Section 4: Linking Libraries

The final step in building a native library with the NDK is to link it with other libraries. You can do this by adding the PREBUILT_SHARED_LIBRARY variable to your Android.mk file.

```
LOCAL_PAT
```

This will allow you to link your library with other libraries that you have built using the NDK.

## Section 5: Conclusion

In this lesson, we learned about building native libraries with the NDK. We covered the basics of setting up a project, creating a library, and linking it with other libraries. By following the steps outlined in this lesson, you can build your own native libraries and use them in your Android applications.

Glossary:
- NDK: Native Development Kit
- PREBUILT_SHARED_LIBRARY: Variable used to specify a prebuilt shared library to link against.
- LOCAL_PAT: Variable used to specify a path to a local file.

## Appendix: Example Project Structure

Here is an example of how an NDK project might be structured:

```
project
|-- jni
|   |-- CMakeLists.txt
|   |-- Android.mk
|   |-- src

Manga is a popular form of Japanese comic book that has become popular worldwide. It is a visual storytelling medium that combines text, images, and symbols to convey stories and messages. In this lesson, we will learn how to read manga, starting with the basics and moving on to more advanced techniques.
Section 1: Understanding the Basics
- Manga is read from right to left, unlike traditional Western comics which are read from left to right.
- The first page of a manga chapter is usually the cover page, which features the title of the series, the author's name, and any relevant information about the chapter.
- The main body of the manga consists of panels, which are rectangular frames that contain the illustrations and text.
- Manga panels can vary in size, but they are usually smaller than those found in Western comics.
- Manga uses a variety of visual cues to convey emotion and action, including facial expressions, body language, and background details.
Section 2: Reading Manga Panels
- Manga panels are usually arranged in a horizontal flow, with each panel containing a single moment in time.
- However, some manga artists use a technique called "speed lines" to show multiple moments happening simultaneously.
- Manga panels can also be arranged in a vertical flow, with each panel representing a different level of depth or perspective.
- Manga artists may use sound effects to convey a character's actions or emotions, such as "bam" or "thud."
Section 3: Understanding Manga Genres
- Manga comes in many different genres, including shoujo (for girls), shounen (for boys), and josei (for women).
- Each genre has its own unique style and themes, so it's important to know what you're getting into before you start reading.
- Some popular manga genres include action, romance, comedy, fantasy, and science fiction.
Section 4: Reading Manga in Context
- Manga is often read in conjunction with other forms of media, such as anime (Japanese animated television shows) or video games.
- Understanding the context of a manga can help you better understand the story and characters.
- Manga often references pop culture, politics, and current events, so it's helpful to have some knowledge of these topics.
Conclusion:
Reading manga can be a fun and engaging way to learn about Japanese culture and language. By understanding the basics of manga and exploring different genres, you can develop a deeper appreciation for this unique art form.

Lesson Title: Implicit Surface Polygonizer

Introduction:
An implicit surface polygonizer is a software tool that creates a 3D model from a set of points or a cloud of data points. It works by creating a mesh that connects these points, forming a surface that represents the shape of the object being modeled. In this lesson, we will learn about the basics of implicit surface polygonization, including how it works, its applications, and its limitations.

Section 1: What is Implicit Surface Polygonization?

Implicit surface polygonization is the process of creating a 3D model from a set of data points. These points can be generated from a scan of an object or a set of measurements taken by a sensor. The software then creates a mesh that connects these points, forming a surface that represents the shape of the object being modeled.

Implicit surface polygonization is often used in computer-aided design (CAD) and computer-aided manufacturing (CAM) software. It is also used in video games, animation, and virtual reality.

Section 2: How does Implicit Surface Polygonization work?

Implicit surface polygonization works by creating a mesh that connects the data points. This mesh is formed by dividing the space into smaller sections called cells. The software then determines which cells contain data points and connects them with edges. Finally, it connects the edges to form a surface that represents the shape of the object being modeled.

There are several algorithms used for implicit surface polygonization, including marching cubes, marching tetrahedra, and Delaunay triangulation. Each algorithm has its own strengths and weaknesses, and the choice of algorithm depends on the specific needs of the user.

Section 3: Applications of Implicit Surface Polygonization

Implicit surface polygonization has many applications in various fields. Some of these applications include:

- Architecture: Architects use implicit surface polygonization to create 3D models of buildings and other structures.
- Engineering: Engineers use implicit surface polygonization to design and analyze products and machines.
- Video games: Game developers use implicit surface polygonization to create realistic environments and characters.
- Virtual reality: VR developers use implicit surface polygonization to create immersive experiences.

Section 4: Limitations of Implicit Surface Polygonization

While implicit surface polygonization is a powerful tool, it has some limitations:

- Resolution: The resolution of the final model depends on the number and distribution of data points. If there are not enough data points, the model may not be accurate enough.
- Noise: Noisy data can lead to artifacts in the final model. This can be mitigated by smoothing techniques, but it may still affect the accuracy of the model.
- Complex shapes: Implicit surface polygonization may struggle to accurately model complex shapes, such as organic forms or highly irregular geometries.

Conclusion:

In this lesson, we learned about implicit surface polygonization, its applications, and its limitations. We also explored how it works and some of its practical uses. By understanding the basics of implicit surface polygonization, we can appreciate its importance in various fields and its potential for future advancements.

Title: Felt Making and Toy Creation

---

# Lesson 1: Introduction to Felt Making

Felt is a unique material that can be made from wool or other fibers. It has been used for centuries to create clothing, rugs, and other household items. In this lesson, we will learn about the basics of felt making and how it can be used to create toys and gifts.

## Section 1: What is Felt?

Felt is a type of fabric that is made by matting together fibers, usually wool. The process involves pressing and condensing the fibers until they become a solid piece of material. Felt can be made in many different colors and textures, making it versatile for creating a wide range of items.

## Section 2: How is Felt Made?

There are several ways to make felt, but the most common method is called wet felting. In this process, wool fibers are first carded (disentangled) and then rolled into a ball called a batt. The batt is then placed on a surface and covered with water and soap. A layer of fiber, called a backing, is placed on top of the batt, and the whole thing is rolled out and smoothed. The water and soap cause the fibers to stick together, creating a strong and durable material.

## Section 3: Creating Toys and Gifts with Felt

Once you have learned how to make felt, you can use it to create all sorts of fun and creative items. Here are some ideas:

1. Hats - Felt hats are a great way to protect yourself from the sun or cold weather. You can make a simple hat using a circular piece of felt or create a more intricate design with different shapes and colors.

2. Brooches - Felt brooches are a fun and easy way to add color and personality to your clothes. You can make simple shapes or more complex designs using different types of wool fibers.

3. Dolls - Felt dolls are a great activity for kids or adults who love to craft. You can make simple dolls using basic shapes or create more detailed designs with different facial expressions and outfits.

## Section 4: Conclusion

In this lesson, we learned about what felt is and how it can be made. We also explored some of the many ways that felt can be used to create fun and creative toys and gifts. With a little bit of practice and patience, you too can learn how to make felt and create your own unique items.
