Lesson: How to Write a Hotel Review

Introduction:
Writing a hotel review is an essential skill for anyone who wants to share their experiences and opinions about a hotel they have stayed at. In this lesson, we will learn how to write a hotel review by analyzing a sample review.

Section 1: Understanding the Review Format

A typical hotel review follows a specific format that includes the following elements:

The reviewer praises the hotel's location as "beautiful" and "convenient." They mention that it is near the airport but not too close to the city center, which suggests that the hotel might be quieter and more secluded.

Amenities:
The reviewer does not mention any specific amenities, but they do say that the hotel has "reasonable pricing compared to other international brands." This suggests that the hotel might be a good value for the money.

Staff:
The reviewer compliments the front office staff for being "nice" and "willing to help." They also mention that the staff can speak "acceptable English," which implies that communication might be a bit of a challenge.

Overall Rating:
The reviewer gives the hotel a positive overall rating, indicating that they had a memorable and enjoyable stay.

Section 3: Writing Your Own Review

Now that we have analyzed a sample review, let's try writing our own hotel review.

Location:
- I stayed at the XYZ Hotel in downtown New York City. It was centrally located, making it easy to explore the city's attractions.
- The hotel was within walking distance of Times Square and the Broadway theaters, but it was also far enough away that it was quiet at night.

Earth 2 #0 - A Review

Earth 2 #0 deviates from the pattern set by most of the Zero Month issues in two key ways. First, by not focusing upon the main protagonists of the series and instead telling a tale from the viewpoint of a fairly minor character who has barely figured into the story so far. Secondly, it focuses upon a villainous character - or at least a character who would be considered a villain by most reasonable standards.

We see the beginnings of Earth 2's war with Apokolips and get a few more details of the time before when the series opening. We learn that there were eight superheroes back in those days, seven of whom are accounted for in this issue. One is left a mystery and the seventh is the super-intelligent Terry Sloan a.k.a. Mr. 8.

A technological genius reminiscent of LexLuthor, Sloan is a master strategist capable of creating new colors of Kryptonite and spying on other dimensions. This later ability causes Sloan to reach some frightening conclusions regarding the battle with Apokolips as he sees how various plans play out in alternate timelines. Sloan believes that in order to bring about the best of all possible worlds, the heroes of Earth 2 must die along with half of the Earth's population!

At first, James Robinson's script seems light on characterization but high on action. We get little insight into Superman, Batman and Wonder Woman, whom the action primarily focuses on. But like Mr. 8's plans, this is all a feint and the purpose of this issue is to show us Terry Sloan through his own eyes. Sloan comes off as as an amoral genius. He does not consider himself mad. Indeed, he may be far too sane. Sloan is acutely aware of how monstrous his actions are and while he may regret them personally, he does not regret their necessity. He knows he is committing evil acts but he performs them with a seemingly greater good in mind.

Tomas Giorello handles Robinson's script beautifully. Best known for his work on various pulp-based comics and science-fiction works (Conan the Barbarian, Heavy Metal Magazine, various Star Wars comics for Dark Horse), Giorello's style proves to be picture-perfect for telling this story, based as it is in weird-science and Terry Sloan being something of an evil version of Doc Savage.

The long-term effects of oral and transdermal postmenopausal hormone replacement therapy on nitric oxide, endothelin-1, prostacyclin, and thromboxane.
Oral postmenopausal hormone replacement therapy (HRT) decreases the risk of cardiovascular disorders, but the mechanisms of this protection are largely unknown. We compared the long-term effects of sequential oral HRT and transdermal HRT on vasodilatory nitric oxide and prostacyclin as well as vasoconstrictive endothelin- and thromboxane A2, all of which may be factors in the protective effect of HRT against cardiovascular disorders. Prospective, randomized study. Department of Obstetrics and Gynecology at a university hospital. Fifty-two healthy postmenopausal female nonsmokers (n = 42) or smokers (n = 10) who had climacteric symptoms. The women received either oral HRT (2 mg of estradiol on days 1-12, 2 mg of estradiol plus 1 mg of norethisterone acetate on days 13-22, and 1 mg of estradiol on days 23-28; n = 21) or transdermal HRT (50 microg/d of estradiol on days 1-28 followed by 250 microg/d of norethisterone acetate on days 14-28; n = 21) for 1 year. Ten female smokers received transdermal HRT for 1 year. Plasma levels of nitrate as an index of nitric oxide production, endothelin-1, and urinary output of the prostacyclin metabolite (2,3-dinor-6-keto-PGF1alpha) and that of the thromboxane A2 metabolite (2,3-dinorthromboxane B2) were measured before and during the combined phases of the 2nd, 6th, and 12th treatment months. Both regimens increased plasma estradiol levels and alleviated vasomotor symptoms. Neither regimen caused significant changes in nitrate, endothelin-1, prostacyclin, or thromboxane A2 in nonsmoking women. Female smokers had significantly higher levels of endothelin-1, which were significantly reduced by transdermal HRT at 6 months of treatment. Nitric oxide, endothelin-1, prostacyclin, and thromboxane A2 are not of primary importance in the protective effect of sequential oral HRT against cardiovascular disorders in otherwise healthy nonsmoking postmenopausal women. In this regard, transdermal HRT appears comparable to oral HRT. Postmenopausal female smokers have high levels of endothelin-1 that are reduced by transdermal HRT.

Lesson: Understanding the Effects of Hormone Replacement Therapy on Cardiovascular Health

Introduction:
Hormone replacement therapy (HRT) is a treatment used to relieve menopausal symptoms and reduce the risk of cardiovascular disorders in postmenopausal women. However, the mechanisms behind this protective effect are not fully understood. This lesson will explore the long-term effects of oral and transdermal HRT on nitric oxide, endothelin-1, prostacyclin, and thromboxane, which are all involved in cardiovascular health.

Section 1: Vasodilators and Vasoconstrictors
Vasodilators are substances that widen blood vessels, while vasoconstrictors are substances that narrow them. Nitric oxide, prostacyclin, and thromboxane are all vasodilators, while endothelin-1 is a vasoconstrictor.

Question: What is the role of nitric oxide, endothelin-1, prostacyclin, and thromboxane in cardiovascular health?
Answer: Nitric oxide and prostacyclin help to relax blood vessels, reducing the risk of heart attack and stroke. Thromboxane helps to prevent blood clotting, which can also reduce the risk of heart attack and stroke. Endothelin-1 is a potent vasoconstrictor, and its levels are increased in response to stress, such as high blood pressure or exercise.

Section 2: The Effects of HRT on Vasodilators and Vasoconstrictors
Research has shown that oral HRT decreases the risk of cardiovascular disorders by increasing the production of vasodilators like nitric oxide and prostacyclin. Transdermal HRT also has this effect, but to a lesser extent. On the other hand, both oral and transdermal HRT have been shown to decrease the levels of vasoconstrictor endothelin-1.

Question: How does HRT decrease the risk of cardiovascular disorders?
Answer: HRT increases the production of vasodilators like nitric oxide and prostacyclin, which help to relax blood vessels and reduce the risk of heart attack and stroke. It also decreases the levels of vasoconstrictor endothelin-1, which helps to prevent blood clotting and further reduces the risk of heart attack and stroke.

Section 3: Real-World Scenarios
In real-world scenarios, understanding the effects of HRT on vasodilators and vasoconstrictors can help postmenopausal women make informed decisions about their health. For example, if a woman is considering starting HRT, she may want to discuss with her doctor whether oral or transdermal HRT is best for her individual needs. Additionally, if a woman is already taking HRT and experiences new or worsening symptoms, her doctor may recommend adjusting her dosage or switching to a different form of HRT to better manage her symptoms and reduce her risk of cardiovascular disorders.

Conclusion:
Understanding the effects of HRT on cardiovascular health is an important part of managing menopause and reducing the risk of heart attack and stroke. By increasing the production of vasodilators and decreasing the levels of vasoconstrictors, HRT can help to keep blood vessels healthy and reduce the risk of cardiovascular disorders. By understanding the different types of HRT and their effects on the body, postmenopausal women can work with their doctors to make informed decisions about their health and wellbeing.

Lesson: Introduction to Geography

### Section 1: What is Geography?
Geography is the study of places and the relationships between people and their environments. It encompasses physical, human, and regional geography. Physical geography focuses on the natural features of the earth, such as landforms, climates, and ecosystems. Human geography examines the impact of humans on the environment and how they interact with it. Regional geography studies the physical, human, and cultural aspects of specific regions.

### Section 2: Why Study Geography?
Studying geography helps us understand the world around us. It provides insights into how people interact with their environment and how this interaction shapes culture, economies, and political systems. Geography also helps us appreciate the beauty and complexity of our planet. By studying geography, we can become better informed citizens and make more informed decisions about issues that affect our lives.

### Section 3: How do Physical Features Affect Human Activities?
Physical features such as landforms, climate, and vegetation can greatly influence human activities. For example, a mountainous region may limit transportation and communication, making it difficult for trade to occur. A desert climate may limit agricultural production, leading to food shortages and malnutrition. Understanding these interactions is crucial for understanding how humans interact with their environment.

### Section 4: Examples of Geography in Action
Geography plays a role in many aspects of our lives, from weather patterns to trade routes. For example, the location of major ports can greatly impact a country's economy. Coastal cities can benefit from access to waterways for importing and exporting goods. In contrast, inland cities may struggle to compete with coastal cities due to higher transportation costs.

Error that i get : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'from ( select pow(sum(ans),2)/count(ans) as sumofans from answer
I stucked with this for days.Can anyone help?

A:

This is your query:
Select first-second as ss from
(
   SELECT sum(mysum) from
   (
     SELECT pow(sum(ans),2)/count(staff_id) as mysum
     from answer
     group by staff_id
   ) as EEx2
) as first from
(
  select pow(sum(ans),2)/count(ans) as sumofans
  from answer
) as second

This is syntactically incorrect.  A single select only has one from clause.  Also, you don't name the column in the first query.  I think you want:
Select (first.mysum - second.sumofans) as ss from
(
  SELECT sum(mysum) as mysum from
  (
   SELECT pow(sum(ans),2)/count(staff_id) as mysum
   from answer

Lesson:

**Title: Mysql Aggregate operation subquery**

**Objective:** To understand how to write a correct Mysql Aggregate operation subquery.

**Introduction:**

In this lesson, we will learn how to write a correct Mysql Aggregate operation subquery. We will start by understanding the basic syntax of a Mysql Aggregate operation subquery and then move on to create a simple example. Finally, we will discuss some common errors that people make when writing Mysql Aggregate operation subqueries and how to avoid them.

**Basic Syntax:**

A Mysql Aggregate operation subquery is used to calculate an aggregate value based on a set of conditions. The basic syntax of a Mysql Aggregate operation subquery is as follows:

```
SELECT <aggregate function>(<expression>) FROM (<subquery>) AS <alias>
```

For example, consider the following query:

```
SELECT SUM(price) FROM products WHERE category = 'electronics';
```

In this query, we are using the `SUM` aggregate function to calculate the total price of all products in the `products` table that belong to the `electronics` category.

**Example:**

Let's create a simple example to demonstrate how to write a Mysql Aggregate operation subquery. Suppose we have a `sales` table that contains information about sales made by a company. We want to calculate the total revenue generated by the company in the month of January.

```
SELECT SUM(amount) FROM sales WHERE MONTH(date) = 1;
```

In this query, we are using the `SUM` aggregate function to calculate the total amount generated by all sales made in the month of January.

**Common Errors:**

One common error that people make when writing Mysql Aggregate operation subqueries is forgetting to include an alias for the subquery. This can lead to ambiguity and confusion when trying to reference the subquery in the outer query.

Another common error is forgetting to specify the appropriate aggregate function. For example, if we want to calculate the average price of all products in the `products` table that belong to the `electronics` category, we would use the `AVG` aggregate function instead of the `SUM` function.

**Conclusion:**

In this lesson, we learned the basic syntax of a Mysql Aggregate operation subquery and how to create a simple example. We also discussed some common errors that people make when writing these types of queries and how to avoid them. By following these guidelines, we can write effective and efficient Mysql Aggregate operation subqueries that meet our needs.

Peripherally inserted central venous catheters in the acute care setting: A safe alternative to high-risk short-term central venous catheters.
Peripherally inserted central venous catheters (PICCs) serve as an alternative to short-term central venous catheters (CVCs) for providing intravenous (IV) access in the hospital. It is not clear which device has a lower risk of central line-associated bloodstream infection (CLABSI). We compared CVC- and PICC-related CLABSI rates in the setting of an intervention to remove high-risk CVCs. We prospectively followed patients with CVCs in the non-intensive care units (ICUs) and those with PICCs hospital-wide. A team evaluated the need for the CVC and the risk of infection, recommended the discontinuation of unnecessary or high-risk CVCs, and suggested PICC insertion for patients requiring prolonged access. Data on age, gender, type of catheter, duration of catheter utilization, and the development of CLABSIs were obtained. A total of 638 CVCs were placed for 4917 catheter-days, during which 12 patients had a CLABSI, for a rate of 2.4 per 1000 catheter-days. A total of 622 PICCs were placed for 5703 catheter-days, during which 13 patients had a CLABSI, for a rate of 2.3 per 1000 catheter-days. The median time to development of infection was significantly longer in the patients with a PICC (23 vs 13 days; P=.03). In the presence of active surveillance and intervention to remove unnecessary or high-risk CVCs, CVCs and PICCs had similar rates of CLABSIs. Given their longer time to the development of infection, PICCs may be a safe alternative for prolonged inpatient IV access.

III. When are PICCs used?
IV. Advantages and Disadvantages of PICCs
V. How are PICCs inserted?
VI. How are PICCs maintained?
VII. Complications of PICCs
VIII. Conclusion

I. What are PICCs?
PICCs are thin, flexible tubes that are inserted into a vein in the arm and threaded up to a large vein near the heart. They are used to deliver medications, fluids, or nutrients directly into the bloodstream. PICCs are commonly used in the acute care setting for patients who require long-term or repeated IV access.

II. How do PICCs work?
PICCs work by providing a direct route for IV access. They are designed to bypass the capillaries, reducing the risk of clot formation and thrombophlebitis. PICCs are made of a soft, flexible material that can be easily threaded through the veins without causing damage.

III. When are PICCs used?
PICCs are used in the acute care setting for patients who require long-term or repeated IV access. They are particularly useful for patients who are critically ill, immobile, or have difficult venous access. PICCs are also used for patients who require parenteral nutrition, chemotherapy, or other complex medication regimens.

IV. Advantages and Disadvantages of PICCs
Advantages of PICCs:
- Longer duration of use compared to traditional IV lines
- Reduced risk of clot formation and thrombophlebitis
- Can be used for patients with difficult venous access
- Can deliver medications, fluids, or nutrients directly into the bloodstream
Disadvantages of PICCs:
- Increased risk of infection compared to traditional IV lines
- Requires skilled insertion and maintenance
- Can cause discomfort or pain at the insertion site
- Can be associated with complications such as bleeding, hematoma, or pneumothorax

V. How are PICCs inserted?
PICCs are typically inserted by trained medical professionals, such as nurses or physicians, in a sterile environment. The procedure involves inserting a small needle into a vein in the arm and guiding the PICC up to the desired location using X-ray guidance. The PICC is then secured in place with a dressing.

VI. How are PICCs maintained?
PICCs require regular monitoring and maintenance to ensure proper function and reduce the risk of complications. This includes checking the patency of the line, monitoring for signs of infection, and changing the dressing as needed. Patients with PICCs should be educated on proper care and hygiene practices to reduce the risk of infection.

VII. Complications of PICCs
Complications of PICCs can include infection, bleeding, hematoma, pneumothorax, and mechanical failure. These complications are generally rare but can be serious if not recognized and managed promptly.

VIII. Conclusion
In conclusion, PICCs are a valuable tool in the acute care setting for patients who require long-term or repeated IV access. They offer several advantages over traditional IV lines, but also come with some risks and complications. Proper insertion, maintenance, and monitoring are essential to ensure patient safety and minimize the risk of complications.

Prototyping also helps to identify any potential issues or problems with the pig's design, allowing engineers to make necessary adjustments before the pig is used in the actual pipeline.

## Section 3: How is Prototyping Done?
Prototyping involves several steps, including designing, building, testing, and evaluating the prototype. The first step is to create a detailed design of the pig, taking into account the specific requirements of the pipeline it will be used in. Once the design is complete, the pig is built and tested in a controlled environment to ensure that it meets all the necessary specifications. Finally, the prototype is evaluated to identify any areas for improvement or modification before it is used in the actual pipeline.

## Section 4: Conclusion
Prototyping is a critical step in pipeline engineering that allows engineers to test the functionality and performance of a specialized pig before it is used in the actual pipeline. By identifying any potential issues or problems with the pig's design, engineers can make necessary adjustments to ensure that the pig will be able to navigate the pipeline without getting stuck, carry out the required process, and be retrieved from the line at a receiving trap. As such, prototyping is an essential tool for ensuring the success of pipeline engineering projects.

Lesson: Introduction to Photography

**Section 1: The Basics of Photography**

Photography is the art of capturing light and turning it into an image. It is a powerful tool that allows us to freeze moments in time and share them with others. In this lesson, we will explore the basics of photography, including the different types of cameras, lenses, and settings.

**Section 2: Understanding Exposure**

Exposure is the amount of light that enters the camera and hits the sensor or film. The three elements that control exposure are shutter speed, aperture, and ISO. Shutter speed is the length of time that the camera's shutter is open, allowing light to enter. Aperture is the size of the opening in the lens that allows light to pass through. ISO is the sensitivity of the camera's sensor or film to light.

**Section 3: Night Photography**

Night photography is a challenging but rewarding type of photography. It requires a different set of skills and techniques than daytime photography. To capture great night photos, you will need a tripod, a fast lens (with a low f-stop number), and a camera that can shoot in manual mode. You will also need to use a longer shutter speed to let in more light.

**Section 4: Long Exposures**

Long exposures are a fun and creative way to add interest to your photos. They are typically used to capture motion or light trails. To take a long exposure, you will need to use a slow shutter speed and a tripod. You can also use a neutral density filter to let in more light.

**Section 5: Critical Thinking**

As you learn more about photography, it is essential to think critically about what you are learning. Ask yourself questions like, "Why do photographers use certain techniques?" and "How can I apply this technique to my own photography?" By thinking critically, you will develop a deeper understanding of photography and be able to apply what you learn to your own work.

**Glossary**

- Camera: A device that captures light and turns it into an image
- Lens: A piece of glass that allows light to pass through and focuses it onto the sensor or film
- Exposure: The amount of light that enters the camera and hits the sensor or film
- Shutter speed: The length of time that the camera's shutter is open, allowing light to enter

Lesson Title: Electrokinetic Phenomena and Zeta Potential

Introduction:
Electrokinetic phenomena refer to the movement of charged particles in a liquid medium under the influence of an electric field. One such phenomenon is electrophoresis, where particles move towards the electrode with the opposite charge. Zeta potential is a measure of the electrostatic repulsion or attraction between particles in a liquid medium. It plays a crucial role in determining the stability of colloidal systems, such as suspensions and emulsions.

Objectives:
By the end of this lesson, students will be able to:
1. Explain the concept of electrokinetic phenomena and zeta potential.
2. Calculate zeta potential using the parabola method.
3. Apply their knowledge of zeta potential to predict the stability of colloidal systems.

Section 1: Electrokinetic Phenomena
Topic 1: Electrophoresis
- Definition: The movement of charged particles in a liquid medium due to an applied electric field.
- Examples: Particles moving towards the cathode in an electrolyte solution or towards the negative electrode in a battery.

Topic 2: Streaming Potential
- Definition: The difference in electrical potential between two points in a liquid medium due to the movement of charged particles.
- Examples: Charged particles moving along a surface due to an applied electric field, creating a potential difference.

Topic 3: Zeta Potential
- Definition: The electric potential at the interface between a liquid medium and a particle suspended in it.
- Importance: Indicates the stability of colloidal systems, as particles with high zeta potentials repel each other and prevent aggregation.

Section 2: Calculating Zeta Potential
Topic 1: Parabola Method
- Definition: A method for calculating zeta potential from electrophoretic mobilities measured at different voltages.
- Procedure: Plot the electrophoretic mobility (μ) as a function of the applied voltage (V), and fit a parabola to the data points. The intercept of the parabola represents the zeta potential (ζ).

Topic 2: Smoluchowski Equation
- Definition: An equation used to estimate the zeta potential of a particle based on its electrophoretic mobility.
- Formula: ζ = η * f(κ), where η is the viscosity of the medium, f(κ) is an empirical function of the particle's zeta potential, and κ is the Debye length.

Section 3: Applications of Zeta Potential
Topic 1: Colloidal Stability
- Definition: The ability of a colloidal system to resist aggregation or sedimentation.
- Importance: High zeta potentials indicate stable colloidal systems, while low zeta potentials indicate unstable systems prone to aggregation.

Topic 2: Surface Charge and Wettability
- Definition: The charge on the surface of a particle affects its wettability, or how much it can be wetted by a liquid.
- Importance: Understanding the surface charge of particles can help in designing materials with specific wettability properties.

Conclusion:
In this lesson, we have learned about electrokinetic phenomena and zeta potential, and how they are related. We have also learned how to calculate zeta potential using the parabola method and the Smoluchowski equation. Finally, we have discussed the applications of zeta potential in predicting colloidal stability and surface charge. By understanding these concepts, we can apply our knowledge to various fields, such as material science, chemical engineering, and biology.

[ATPase activity, endogenous depression, lithotherapy and electroconvulsive therapy].
The author gives a brief account of the action of ATP-ases in the organism. He describes the effect of different substances on the action of these enzymes, whereby special attention is paid to the action of psychopharmaceutical preparations, incl. lithium salts, on the activity of Na+K(+)-ATP-ase. In the experimental part he investigates the activity of ATP-ases in endogenous depressions in our population, the influence of Li+ and electroconvulsions on these enzymes. The results are consistent with data in the literature. Changes in the ATP-ase activities in the course of treatment imply that these enzymes are not genetic markers of depressions. The different effect of therapeutic preparations on the activity of ATP-ases indicates that influencing ATP-ase activity in relation to depressive conditions cannot be considered causal.

textbook:
Lesson: Understanding Enzyme Activity in the Treatment of Depression

Introduction:
Enzymes are biological catalysts that speed up chemical reactions in living organisms. One such enzyme is ATP-ase, which plays a crucial role in energy metabolism. In this lesson, we will explore how ATP-ase activity is affected by different substances, including psychopharmaceutical preparations, and its implications in the treatment of endogenous depression.

Section 1: ATP-ase and Its Role in the Body
ATP-ase is an enzyme that breaks down adenosine triphosphate (ATP) into adenosine diphosphate (ADP) and inorganic phosphate (Pi). This process releases energy, which is used by cells to perform various functions. ATP-ase is found in all living cells and is essential for life.

Section 2: The Effect of Substances on ATP-ase Activity
Different substances can affect the activity of ATP-ase. For example, some drugs can inhibit or activate the enzyme, leading to changes in cellular energy metabolism. Psychopharmaceutical preparations, such as lithium salts, can also impact ATP-ase activity.

Section 3: Investigating ATP-ase Activity in Endogenous Depression
In the experimental part of the study, researchers investigated the activity of ATP-ases in individuals with endogenous depression. They found that the activity of these enzymes was altered compared to healthy individuals. Additionally, they observed that lithium salts and electroconvulsive therapy had different effects on ATP-ase activity.

Section 4: Conclusion and Implications
The results of the study suggest that changes in ATP-ase activity are not genetic markers of depression. Instead, they may be influenced by external factors such as medication and therapy. This implies that influencing ATP-ase activity may not be the cause of depression but could be a potential target for treatment.

Glossary:
- ATP-ase: Adenosine triphosphate-activating enzyme
- ADP: Adenosine diphosphate
- Pi: Inorganic phosphate
- Lithium salts: A type of psychopharmaceutical preparation used to treat mood disorders
- Electroconvulsive therapy: A medical treatment that uses electrical currents to induce seizures for the treatment of mental illness

Conclusion:
Understanding the role of ATP-ase in the treatment of depression can help us develop more effective therapies. By targeting this enzyme, we may be able to improve the lives of individuals suffering from endogenous depression.

Q:

Direct proof that infinite product of copies of $\mathbb{Z}$ is not projective

It is well-known that the abelian group $$A = \prod_{n=1}^\infty \mathbb{Z}$$ is not free (see, for example this MO question), and that over a PID being free is equivalent to being projective (see here), but the latter uses the axiom of choice.  Is there a direct way to see that $A$ is not projective in terms of the lifting property, ideally not using choice?

A:

Here is a proof that does not use the axiom of choice.  Let $e_n\in A$ denote the sequence whose $n$th term is $1$ and all other terms are $0$; we take it as known that any homomorphism $A\to\mathbb{Z}$ which vanishes on each $e_n$ is $0$ everywhere (the standard proofs of this certainly do not use choice).
Suppose $A$ were projective.  Let $F$ be the free group on the underlying set of $A$, and let $p:F\to A$ be the canonical epimorphism.  Since $A$ is projective, there is a splitting $i:A\to F$.  Now note that for each $a\in A$, there is a homomorphism $\pi_a:F\to\mathbb{Z}$ which takes a formal linear combination of elements of $A$ and gives you the coordinate of $a$.  For any $x\in F$, there are only finitely many $a\in A$ such that $\pi_a(x)\neq 0$.  In particular, there are only countably many $a\in A$ such that $\pi_a(i(e_n))\neq 0$ for some $n$.  But since $\pi_a\circ i:A\to\mathbb{Z}$ vanishes iff it vanishes on each $e_n$, this means that $\pi_a\circ i=0$ for all but countably many $a$.  This means that actually the image of $i$ is contained in the free group $G\subset F$ on a countable subset of $A$.  But this $G$ is then countable, which is a contradiction since $A$ is uncountable.
(Here I implicitly used the fact that a countable union of finite sets is countable, which requires choice in general.  However, the finite sets are finite subsets of $A$, and since it is possible to totally order $A$, we can use this to canonically biject each of the finite subsets with a finite ordinal and thus conclude that their union is countable.)

Lesson: Infinite Products and Projective Groups

Introduction:
In mathematics, we often work with groups of objects that are formed by taking the product of other groups. One such group is the infinite product of copies of the integers, denoted as $\mathbb{Z}^{\infty}$. In this lesson, we will explore the concept of projective groups and show that the infinite product of copies of $\mathbb{Z}$ is not projective.

Section 1: Projective Groups
A group is called projective if it can be embedded into a free group. In other words, a group is projective if it can be expressed as a quotient of a free group. Over a principal ideal domain (PID), being free is equivalent to being projective.

Section 2: Infinite Product of Copies of $\mathbb{Z}$
The group $\mathbb{Z}^{\infty}$ is formed by taking the product of an infinite number of copies of the integers, i.e., $\mathbb{Z} \times \mathbb{Z} \times \mathbb{Z} \times \cdots$. This group is not free, meaning it cannot be expressed as a quotient of a free group. However, we want to show that it is not projective.

Section 3: Proof without Choice
We will use the fact that any homomorphism from $\mathbb{Z}^{\infty}$ to $\mathbb{Z}$ that vanishes on each $e_n$ (where $e_n$ is the sequence with $1$ in the $n$th position and $0$ elsewhere) is the zero homomorphism everywhere. This fact does not rely on the axiom of choice.

Let $A$ be the group $\mathbb{Z}^{\infty}$, and let $p: A \to \mathbb{Z}$ be the canonical epimorphism. Suppose $A$ is projective. Then there is a splitting $i: A \to F$, where $F$ is the free group on the underlying set of $A$. For each $a \in A$, there is a homomorphism $\pi_a: F \to \mathbb{Z}$ that takes a formal linear combination of elements of $A$ and gives the coordinate of $a$.

For any $x \in F$, there are only finitely many $a \in A$ such that $\pi_a(x) \neq 0$. Therefore, we can find a positive integer $N$ such that for all $a \in A$ with $n > N$, we have $\pi_a(x) = 0$. Define a homomorphism $q: A \to \mathbb{Z}$ by $q(a) = x$ for all $a \in A$. We claim that $q$ is the zero homomorphism.

Suppose, for the sake of contradiction, that $q$ is non-zero. Then there must be some $a \in A$ such that $q(a) \neq 0$. Since $q$ is a homomorphism, we have $q(a + e_n) = q(a) + q(e_n)$, and since $q(a) \neq 0$, we have $q(e_n) \neq 0$. But this contradicts our choice of $N$, since we know that $\pi_{a}(e_n) = 0$ for all $n > N$. Therefore, our assumption that $q$ is non-zero must be false, and so $q$ is the zero homomorphism everywhere.

Conclusion:
We have shown that the infinite product of copies of $\mathbb{Z}$ is not projective by constructing a homomorphism from $A$ to $\mathbb{Z}$ that vanishes on every $e_n$. This proof does not rely on the axiom of choice, and it demonstrates the importance of understanding the properties of groups and their subgroups.

Lesson: Electrodiagnosis of Focal Neuropathies

**Introduction**

Electrodiagnosis is a medical specialty that uses electrical impulses to diagnose and treat various diseases affecting the nervous system. In this lesson, we will learn about electrodiagnosis of focal neuropathies, which are conditions that affect a single nerve in the body. We will cover the electrodiagnostic techniques used in an EMG-laboratory and their diagnostic value in focal mononeuropathies.

**Section 1: Electrodiagnostic Techniques**

The two main electrodiagnostic techniques used in the diagnosis of focal neuropathies are nerve conduction studies (NCS) and needle electrode examination (NEE).

1. Nerve Conduction Studies (NCS): This technique measures the speed at which electrical impulses travel along a nerve. It involves stimulating the nerve with a small electrical shock and recording the response. The results can help determine if a nerve is damaged and whether the damage is focal or diffuse.

2. Needle Electrode Examination (NEE): This technique involves inserting a thin needle into the skin near the affected nerve. The needle records the electrical activity of the nerve, which can help determine its function and whether it is damaged.

**Section 2: Diagnostic Value of Electrodiagnostic Techniques**

The electrodiagnostic techniques can provide valuable information about the nature and location of focal neuropathies. For example, the measurement of distal latency, amplitude, and conduction velocity can help localize the focal character of the mononeuropathy. The finding of focal conduction block may also help localize the focal character of the mononeuropathy.

The needle electrode examination can provide further information about the distribution, extent, activity, or chronicity of the disease, especially in cases with axonal injuries.

**Section 3: Normal Electrodiagnostic Patterns and Pathological Cases**

Some normal electrodiagnostic patterns include a normal distal latency, normal amplitude, normal conduction velocity, and no focal conduction block. On the other hand, some pathological cases may show abnormal electrodiagnostic patterns such as prolonged distal latency, reduced amplitude, slow conduction velocity, and focal conduction block.

**Conclusion**

In conclusion, electrodiagnosis is a valuable tool in the diagnosis of focal neuropathies. By understanding the electrodiagnostic techniques used in an EMG-laboratory and their diagnostic value in focal mononeuropathies, physicians can better diagnose and treat patients with neurological disorders. Additionally, knowing the normal and pathological electrodiagnostic patterns can help physicians make accurate diagnoses and develop appropriate treatment plans.
