Q:

Check if given string matches one of set of prefixes, effectively

What algorithm to use to check if a given string matches one of set of prefixes, and which prefix from that set?
Other variation: given path and a set of directories, how to check if path is in one of set of directories (assuming that there are no symbolic links, or they do not matter)?
I'm interested in description or name of algorithm, or Perl module which solves this (or can be used to solve this).
Edit
Bonus points for solution which allow to effectively find 'is prefix of' relation between set of strings (set of directories)
For example, given set of directories: foo, foo/bar, foo/baz, quux, baz/quux, baz/quux/plugh the algorithm is to find that foo is prefix of foo/bar and foo/baz, and that baz/quux is prefix of baz/quux/plugh... hopefully without O(n^2) time.

A:

The efficient way to do this would be using a Trie:
http://en.wikipedia.org/wiki/Trie
There is a package for it on CPAN:
https://metacpan.org/pod/Tree::Trie
(never used that package myself though)
You need to consider your what operations need to be the most efficient. The lookup is very cheap in a Trie, but if you only build the trie for one lookup, it might not be the fastest way...

Lesson: Finding Prefixes in a Set of Strings

Introduction:
In computer science, finding prefixes in a set of strings is a common operation. A prefix is a substring that appears at the beginning of another string. In this lesson, we will learn how to efficiently find prefixes in a set of strings using a Trie.

Prerequisites:
- Knowledge of basic data structures like arrays, linked lists, and hash tables.
- Familiarity with the concept of a Trie.

Lesson Plan:
1. Theory
  1.1 What is a Trie?
  1.2 How does a Trie work?
  1.3 Advantages of using a Trie over other data structures.

2. Practice
  2.1 Implementing a Trie in code.
  2.2 Using a Trie to find prefixes in a set of strings.

3. Glossary
  3.1 Trie: A tree-like data structure where each node represents a character in the string.
  3.2 Prefix: A substring that appears at the beginning of another string.

Theory:
1.1 What is a Trie?
A Trie is a tree-like data structure where each node represents a character in the string. It is used to store a set of strings so that the strings can be searched quickly.

1.2 How does a Trie work?
A Trie works by creating a node for each character in the string. Each node has a boolean value indicating whether it is a prefix or not. When a new string is added to the Trie, it is compared to the existing strings in the Trie until a match is found. If no match is found, a new node is created for the last character in the string.

1.3 Advantages of using a Trie over other data structures.
The main advantage of using a Trie over other data structures like hash tables or binary search trees is that it allows for constant-time lookups. This is because the Trie can be traversed in a depth-first manner, allowing for the quick identification of prefixes.

Practice:
2.1 Implementing a Trie in code.
Here is an example implementation of a Trie in Python:
```python
class TrieNode:
    def __init__(self):
        self.value = None
        self.children = {}
        self.is_prefix = False
class Trie:
    def __init__(self):
        self.root = TrieNode()
    def insert(self, word):
        current = self.root
        for c in word:
            if c not in current.children:
                current.children[c] = TrieNode()
            current = current.children[c]
        current.value = word
        current.is_prefix = True
    def find_prefixes(self, word):
        current = self.root
        for c in word:
            if c not in current.children:
                return False
            current = current.children[c]
        return True
```

2.2 Using a Trie to find prefixes in a set of strings.
Here is an example of how to use the Trie to find prefixes in a set of strings:
```python
trie = Trie()
words = ['cat', 'car', 'cart', 'bat', 'bar', 'baz']
for word in words:
    trie.insert(word)
prefixes = trie.find_prefixes('cat')
print(prefixes) # Output: ['cat', 'car', 'cart']
```

Glossary:
3.1 Trie: A tree-like data structure where each node represents a character in the string.
3.2 Prefix: A substring that appears at the beginning of another string.

Conclusion:
In this lesson, we learned about the Trie data structure and how it can be used to efficiently find prefixes in a set of strings. We implemented a Trie in code and used it to find prefixes in a set of strings. We also defined the key terms related to this topic.

A role for serotonin in the elaboration of a differential pattern of activity in sympathetic nerves to kidney and skeletal muscle vasculature.
The role of serotonin (5-HT) in the elaboration of patterns of regional sympathetic discharge evoked from the ventral medulla was examined in cats under Saffan anesthesia. A differential response pattern consisting of an increase in renal sympathetic nerve activity simultaneous with no change in activity to skeletal muscle vasculature was evoked from a group of ventral medullary neurons by microinjection of D,L-homocysteic acid. Subsequent intrathecal administration of the 5-HT receptor antagonist methysergide (200 micrograms) attenuated or abolished the excitatory response to the kidney on restimulation of the medulla, without affecting sympathetic activity to muscle. Methysergide did not affect an excitatory response evoked in the outflow to both the kidney and skeletal muscle vasculature from an adjacent region of the ventral medulla. These results indicate a role for 5-HT in the elaboration of a specific differential pattern of sympathetic response evoked from medullary neurons.

Lesson: The Role of Serotonin in the Elaboration of Sympathetic Nerve Activity
Introduction:
Serotonin is a neurotransmitter that plays an important role in the regulation of various physiological processes. In this lesson, we will explore the role of serotonin in the elaboration of patterns of regional sympathetic discharge, particularly in relation to kidney and skeletal muscle vasculature.
Core Value:
The core value of this lesson is to understand the role of serotonin in the elaboration of patterns of regional sympathetic discharge and its implications in physiological processes.
Section 1: The Role of Serotonin in Sympathetic Nerve Activity
Serotonin is a neurotransmitter that is involved in the modulation of various physiological processes, including the regulation of blood pressure, heart rate, and body temperature. It is also involved in the regulation of the autonomic nervous system, which includes the sympathetic and parasympathetic branches.
In the context of sympathetic nerve activity, serotonin plays a crucial role in the elaboration of a differential pattern of activity in sympathetic nerves to kidney and skeletal muscle vasculature. This means that serotonin helps to modulate the activity of sympathetic nerves in such a way that it increases the activity to the kidney while leaving the activity to the skeletal muscle vasculature unchanged.
Section 2: Experimental Evidence
Experimental evidence suggests that serotonin is involved in the elaboration of patterns of regional sympathetic discharge evoked from the ventral medulla. In cats under Saffan anesthesia, a differential response pattern consisting of an increase in renal sympathetic nerve activity simultaneous with no change in activity to skeletal muscle vasculature was evoked from a group of ventral medullary neurons by microinjection of D,L-homocysteic acid.
Subsequent intrathecal administration of the 5-HT receptor antagonist methysergide (200 micrograms) attenuated or abolished the excitatory response to the kidney on restimulation of the medulla, without affecting sympathetic activity to muscle. Methysergide did not affect an excitatory response evoked in the outflow to both the kidney and skeletal muscle vasculature from an adjacent region of the ventral medulla.
Section 3: Implications and Applications
The findings from this experimental evidence have significant implications for our understanding of the role of serotonin in the regulation of physiological processes. Specifically, it highlights the importance of serotonin in the modulation of sympathetic nerve activity and its implications for the regulation of blood pressure, heart rate, and body temperature.
Furthermore, the findings from this study can be applied in the development of therapeutic interventions for conditions that involve dysregulation of sympathetic nerve activity. For example, drugs that target the 5-HT receptors could be used to modulate sympathetic nerve activity in patients with hypertension or other cardiovascular conditions.
Conclusion:
In conclusion, this lesson has explored the role of serotonin in the elaboration of patterns of regional sympathetic discharge and its implications for physiological processes. By understanding the role of serotonin in the modulation of sympathetic nerve activity, we can gain insights into the regulation of blood pressure, heart rate, and body temperature, and develop therapeutic interventions for conditions that involve dysregulation of sympathetic nerve activity.

Correlation between intravenously supplied energy level and zinc metabolism in laparotomized rats.
We investigated the relationship between intravenous energy loading and zinc status in laparotomized rats. One of three test solutions consisting of 3% amino acid, the same amount of electrolytes (excluding zinc) and different concentrations of glucose were infused through the jugular vein for 5 d. The total energy was 109, 191 and 273 kcal/kg/d, respectively. Significantly positive correlations were observed between infusion energy and rat body weight changes (% of initial value) and between infusion energy and cumulative nitrogen balance. Regarding the zinc status, a negative correlation was found between infusion energy and plasma zinc concentration, and a positive correlation was observed between infusion energy and urinary zinc excretion. There was no significant relationship between infusion energy and hepatic zinc content. These results indicate that the zinc requirement might be increased when infusion energy is elevated and the nutritional status is improved. Zinc supplementation in the post-operative period should be considered in light of not only catabolism but also anabolism. Anabolism may be more important than catabolism in regard to zinc metabolism under relatively mild stress.

Lesson: Correlation Analysis

Introduction:
In this lesson, we will learn about correlation analysis, a statistical method used to determine the relationship between two variables. We will explore the steps involved in conducting a correlation analysis, the different types of correlations, and how to interpret the results.

Step 1: Data Collection
The first step in conducting a correlation analysis is to collect data on the two variables you want to study. This data can be collected through surveys, experiments, or observations.

Step 2: Data Organization
Once you have collected your data, you need to organize it in a table or spreadsheet. This table should include the values for each variable, as well as the corresponding values for the other variable.

Step 3: Calculate the Correlation Coefficient
The next step is to calculate the correlation coefficient, which is a numerical value that represents the strength and direction of the relationship between the two variables. There are several different types of correlation coefficients, including Pearson's r, Spearman's rho, and Kendall's tau. Each of these measures the strength and direction of the relationship differently, so it's essential to choose the appropriate one for your specific research question.

Step 4: Interpret the Results
After calculating the correlation coefficient, you need to interpret the results. A positive correlation coefficient indicates a positive relationship between the two variables, meaning that as one variable increases, so does the other variable. A negative correlation coefficient indicates a negative relationship between the two variables, meaning that as one variable increases, the other variable decreases. A correlation coefficient of zero indicates no relationship between the two variables.

Types of Correlations:
There are several different types of correlations, including:

1. Positive Correlation: This type of correlation occurs when both variables move in the same direction. For example, if one variable increases, the other variable also increases.

2. Negative Correlation: This type of correlation occurs when both variables move in opposite directions. For example, if one variable increases, the other variable decreases.

3. No Correlation: This type of correlation occurs when there is no relationship between the two variables. The correlation coefficient is equal to zero.

Conclusion:
In this lesson, we have learned about correlation analysis, a statistical method used to determine the relationship between two variables. We have explored the steps involved in conducting a correlation analysis, the different types of correlations, and how to interpret the results. By understanding these concepts, we can apply this knowledge to various scenarios and make informed decisions based on data.

At Lincoln Center’s Stanley Kaplan Penthouse, music drips through the air like wax from the candles on the tables scattered throughout the space. At late-night concerts, part of the annual Mostly Mozart Festival, concert-goers can listen to works by and influenced by Mozart while drinking wine and drinking in the view from the tenth floor.

This concert by England’s Tippett Quartet, their debut in Canada, was about time. The Quartet came together in 1998, the year of the passing of their namesake, Sir Michael Tippett. Their first musical offering of the afternoon was Tippett’s Fifth and final String Quartet (1991), with Anna Smith filling in for Jeremy Isaac on second violin.

Music fans love to get the whole picture. We consume box-sets, bootlegs, alternate takes, and artist interviews – all in the name of completeness. Some people say a good CD library should have at least three Eroicas and five Fifths to be complete, while music magazines might recommend more. Of course, live music venues have their own shot at completeness when they schedule a “cycle”.

It would be difficult indeed to imagine an evening of string quartet playing at once more diverse and more brilliant than this. Already one of the world’s finer quartets after only a few years in the public eye, the Quatuor Ebène are notable for their catholic tastes.

The renowned Chilingirian Quartet gave an electrifying performance of celebrated string quartets by Bartok, Haydn and Beethoven at London's Wigmore Hall.The concert began with an outstanding rendition of Bartok’s Fourth String Quartet (1928), which consists of five movements in a loose ‘arch’ form.

Lesson: Understanding Music Festivals

Introduction:
Music festivals are events where people come together to enjoy and appreciate music. These festivals can range from small, local gatherings to large, international events that attract thousands of people. In this lesson, we will explore the different aspects of music festivals, including their history, structure, and impact on society.

Section 1: History of Music Festivals

The first music festival was held in ancient Greece around 500 BCE. It was called the Panathenaic Games and included competitions in music, poetry, and athletics. Over time, music festivals have evolved and become more diverse. For example, the medieval European festival featured minstrels who traveled from town to town performing songs and stories. In the 20th century, jazz and rock music festivals became popular, and today, there are festivals for all genres of music, including electronic, hip-hop, and folk.

Section 2: Structure of Music Festivals

A typical music festival includes several stages where performers play music throughout the day and night. There are usually multiple stages so that different acts can perform simultaneously. In addition to the performances, there are often food vendors, merchandise stands, and other attractions. The festival's organizers must consider many factors when planning the event, such as the number of attendees, the lineup of performers, and safety measures.

Section 3: Impact of Music Festivals on Society

Music festivals have a significant impact on society. They bring people together from all walks of life to enjoy a common interest – music. Festivals also provide an opportunity for artists to showcase their talents and connect with new audiences. Furthermore, music festivals contribute to the economy by generating revenue for local businesses and creating jobs. However, some critics argue that music festivals can lead to environmental damage and negative social consequences, such as drug use and crime.

Conclusion:
In conclusion, music festivals are an essential part of our cultural heritage. They provide a platform for artists to express themselves and connect with fans while contributing to the economy and society. By understanding the history, structure, and impact of music festivals, we can appreciate their significance and enjoy them responsibly.

Lesson: Comparing Cities

Introduction: In this lesson, we will learn how to compare different cities using various metrics such as population, reviews, city data, and overall city score. We will use the example of Glendale Heights, IL, but the concepts can be applied to any other cities.

Section 1: Population

The first step in comparing cities is to look at their population. This gives us an idea of the size of the city and how many people live there. We can use the following formula to calculate the population density:

Population Density = (Total Population) / (Land Area)

For example, let's say that Glendale Heights has a total population of 30,000 and a land area of 10 square miles. We can calculate its population density as follows:

Population Density = (30,000) / (10) = 3,000 people per square mile

Questions:
- How does the population density of Glendale Heights compare to other cities in the same state?
- What is the average population density of cities in the United States?

Answer:
- To answer the first question, we would need to gather data on the population densities of other cities in Illinois. Once we have that data, we can compare Glendale Heights to those cities.
- The average population density of cities in the United States varies depending on the region. According to the US Census Bureau, the national average population density in 2019 was 337 people per square mile.

Section 2: Reviews

Another way to compare cities is by looking at online reviews. These can give us an idea of what it's like to live in or visit a particular city. We can use the following formula to calculate the average rating of a city:

Average Rating = (Number of Ratings) / (Number of Reviewers)

For example, let's say that Glendale Heights has 500 ratings and 100 reviewers. We can calculate its average rating as follows:

Average Rating = (500) / (100) = 5

Questions:
- How does the average rating of Glendale Heights compare to other cities in the same state?
- What factors contribute to a city having a high or low average rating?

Answer:
- To answer the first question, we would need to gather data on the average ratings of other cities in Illinois. Once we have that data, we can compare Glendale Heights to those cities.
- Factors that contribute to a city having a high or low average rating include the quality of schools, crime rates, job opportunities, cost of living, and amenities available in the city.

Section 3: City Data

City data can also provide valuable information when comparing cities. We can use the following formula to calculate the median household income:

Median Household Income = (Total Household Income) / (Number of Households)

For example, let's say that Glendale Heights has a total household income of $1 billion and 10,000 households. We can calculate its median household income as follows:

Median Household Income = ($1,000,000,000) / (10,000) = $100,000

Questions:
- How does the median household income of Glendale Heights compare to other cities in the same state?
- What factors contribute to a city having a high or low median household income?

Answer:
- To answer the first question, we would need to gather data on the median household incomes of other cities in Illinois. Once we have that data, we can compare Glendale Heights to those cities.
- Factors that contribute to a city having a high or low median household income include the availability of high-paying jobs, cost of living, and the education level of the workforce.

Conclusion:

By using the population density, average rating, and median household income, we can compare Glendale Heights to other cities. However, these are just a few examples of the many metrics that can be used to compare cities. As we continue to explore different metrics, we will gain a deeper understanding of what makes each city unique.

Lesson: Understanding the Impact of Diet on Neurogenesis

Introduction:
Neurogenesis is the process of creating new neurons in the brain. It is an essential part of brain function and development. In this lesson, we will explore how diet can impact neurogenesis, specifically in females.

Core Value:
The core value of this lesson is that diet plays a significant role in neurogenesis, and females are more susceptible to the negative effects of a high-fat diet on brain health.

Section 1: Understanding Neurogenesis

Topic 1: What is neurogenesis?
Neurogenesis is the process by which new neurons are created in the brain. It occurs throughout an individual's life, but the rate of neurogenesis decreases as we age.

Topic 2: How does diet impact neurogenesis?
Diet can have a significant impact on neurogenesis. A balanced diet that includes healthy fats, proteins, and carbohydrates is essential for optimal brain function. On the other hand, a high-fat diet can impair neurogenesis and lead to negative health outcomes.

Section 2: The Impact of High-Fat Diets on Female Mice

Topic 1: What did the study find?
Robison et al. conducted a study in which they fed one group of mice a high-fat diet and another group a normal diet for 18 weeks. They found that only female mice on the high-fat diet experienced impaired neurogenesis in the hippocampus.

Topic 2: Why were female mice more affected by the high-fat diet?
The study found that female mice on the high-fat diet had fewer newborn and developing neurons than male mice on the same diet. This suggests that females are more susceptible to the negative effects of a high-fat diet on brain health.

Section 3: Applying the Findings to Real-World Scenarios

Topic 1: How can we apply this knowledge to our lives?
Understanding the impact of diet on neurogenesis can help us make more informed decisions about what we eat. Consuming a balanced diet that includes healthy fats, proteins, and carbohydrates is essential for optimal brain function.

Topic 2: What are some examples of high-fat foods?
Some examples of high-fat foods include fast food, processed snacks, and sugary drinks. While these foods may taste good, they can have negative effects on our brain health if consumed in excess.

Conclusion:
In conclusion, understanding the impact of diet on neurogenesis is essential for maintaining optimal brain health. This lesson has explored how a high-fat diet can impair neurogenesis in female mice and why females are more susceptible to the negative effects of such a diet. By applying this knowledge to our lives, we can make more informed decisions about what we eat and prioritize a balanced diet that supports neurogenesis.

Q:

The last & the first day of a month in Google Spreadsheets

What is the way to get the first and last day of the previous month in Google Spreadsheet? I tried several ways to solve this issue with no success.

A:

If you had your base date in A1,
the following formula would be good for the first day of the previous month:
=date(year(A1),month(A1)-1,1)

It's even simpler to find the last day of the previous month:
=eomonth(A1,-1)

A:

for the last day of the previous month  (international)
=eomonth(now();-1)

for the last day of the previous month  (USA)
 =eomonth(now(),-1)

for the first day of the previous month (international)
=eomonth(now();-2)+1

for the first day of the previous month (USA)
    =eomonth(now(),-2)+1

Lesson: Using Google Spreadsheets to Find First and Last Day of Previous Month

**Introduction**

In this self-taught lesson, we will learn how to use Google Spreadsheets to find the first and last day of the previous month. This skill is useful in many fields, such as finance, project management, and time tracking.

**Section 1: Theoretical Concepts**

- A cell in Google Spreadsheets can contain a date, which is represented by a serial number.
- The `DATE` function converts a year and month into a date.
- The `EOMONTH` function returns the serial number of the last day of a given month.

**Section 2: Practical Examples**

Let's say our base date is January 1, 2022 (A1). We want to find the first day of the previous month.

1. Enter the formula `=DATE(YEAR(A1),MONTH(A1)-1,1)` in a new cell. Press enter. The result should be December 1, 2021.

2. Enter the formula `=EOMONTH(A1,-1)` in a new cell. Press enter. The result should be December 1, 2021.

Now let's find the last day of the previous month.

1. Enter the formula `=EOMONTH(A1,-1)` in a new cell. Press enter. The result should be November 30, 2021.

2. Enter the formula `=EOMONTH(NOW();-1)` in a new cell. Press enter. The result should be November 30, 2021.

**Section 3: Self-Debating Discussions**

Why do we need to adjust the month parameter in `EOMONTH` by -1 instead of -2?

- The `EOMONTH` function returns the serial number of the last day of a given month. If we subtract -2 from the current month, we will get the last day of the previous month, which is not what we want. Instead, we need to subtract -1 to get the first day of the previous month.

**Glossary**

- **Serial Number**: A unique identifier assigned to each cell in Google Spreadsheets that represents the position of the cell within its range.
- **Date Function**: A function that converts a year and month into a date.
- **EOMONTH Function**: A function that returns the serial number of the last day of a given month.

**Conclusion**

In this lesson, we learned how to use Google Spreadsheets to find the first and last day of the previous month. We covered theoretical concepts, practical examples, and self-debating discussions. By applying these skills to new problems, we can easily determine the first and last day of any previous month.


text: Sub title: Lessons for Our Times. Edited By: Tara Sethia, Anjana Narayan. This inspiring volume presents unique insights from leading international scholars, activists, educators and thought leaders on the contemporary relevance of Gandhi’s ideas and actions. The essays here reveal that for Gandhi legitimate coercion by the state in certain cases was compatible with ahimsa; a balance between spiritual and material values was essential for a true civilization, and swaraj anchored in self-discipline and self-restraint was an imperative for sustainable ways of life. The essays also illustrate how Gandhi has been instructive for ethical business leadership, socially responsible investing and entrepreneurship, transformative education and caring for nature. This book compellingly reaffirms the continuing significance of Gandhi’s wisdom for a just and peaceful world.

**Lesson 1: Ahimsa and Non-Violence**

**Introduction:** In this lesson, we will learn about the concept of ahimsa and non-violence as advocated by Mahatma Gandhi. We will explore how these principles can be applied in our daily lives and how they can help us become better individuals.

**Theoretical Concept:** Ahimsa is a principle of non-violence that emphasizes respect for all living beings. It is based on the belief that violence only begets more violence and that peaceful means are more effective in achieving desired outcomes.

**Practical Example:** Imagine you are walking down the street and see someone drop their wallet. You have two options: you can either pick up the wallet and return it to the owner, or you can take the money and walk away. If you choose the first option, you are practicing ahimsa because you are not causing harm to anyone. However, if you choose the second option, you are violating the principle of ahimsa because you are causing harm to the person who lost their wallet.

**Real-World Scenario:** Non-violence and ahimsa are not just theoretical concepts, they are also practical tools that can be used to bring about positive change in the world. For example, during the Indian independence movement, Gandhi advocated for non-violent protests and civil disobedience as a way to fight against British colonialism. These tactics were successful in bringing about change without resorting to violence.

**Questions and Answers:**

Q: How can I practice ahimsa in my daily life?
A: There are many ways to practice ahimsa in your daily life. Some examples include being kind to animals, avoiding meat and dairy products, practicing patience and tolerance, and treating everyone with respect and compassion.

Q: Isn't it naive to believe that non-violence can solve all problems?
A: While it may seem naive, the principle of non-violence has been proven to be effective in many situations. It requires creativity, courage, and determination to find peaceful solutions to problems, but it is possible.

**Conclusion:** In conclusion, the principle of ahimsa and non-violence is an important tool for creating a more just and peaceful world. By practicing non-violence in our daily lives, we can become better individuals and contribute to a more positive society.

**Glossary:**
- Ahimsa: A principle of non-violence that emphasizes respect for all living beings.
- Non-violence: The practice of avoiding harm to others and resolving conflicts without resorting to violence.
- Civil disobedience: A form of political activism in which individuals refuse to obey certain laws or government demands as a way of protesting against injustice.

Lesson: The Importance of Quality Service in Automotive Repairs

**Introduction:**

In this lesson, we will explore the importance of quality service in automotive repairs. We will learn about the benefits of choosing a reputable mechanic who is trained by the manufacturer and understands the intricacies of your vehicle. By the end of this lesson, you will be able to identify the key factors that contribute to quality service and make an informed decision when choosing a mechanic for your car.

**Section 1: Understanding Quality Service**

Quality service refers to the level of service you receive when you take your car for repairs or maintenance. It encompasses several factors, including the technical knowledge of the mechanic, the quality of the parts used, and the efficiency of the repair process. Quality service is important because it ensures that your car is repaired correctly and safely, and that you are not overcharged for unnecessary repairs.

**Section 2: The Benefits of Choosing a Reputable Mechanic**

Choosing a reputable mechanic who is trained by the manufacturer and understands the intricacies of your vehicle has several benefits. Firstly, such mechanics are familiar with the latest technology and software used in modern cars, which means they can diagnose and fix problems more accurately and efficiently. Secondly, they have access to genuine parts and tools, which ensures that your car is repaired with high-quality components. Finally, reputable mechanics are more likely to stand behind their work with warranties and guarantees, giving you peace of mind that your car is in good hands.

4. Clear communication: A good mechanic should communicate clearly and transparently about the problems with your car, the proposed solutions, and the costs involved.
5. Warranty and guarantee: A reputable mechanic should stand behind their work with a warranty or guarantee, giving you confidence in the quality of the repairs.

**Section 4: Practical Examples**

Let's consider a practical example to illustrate the importance of quality service in automotive repairs. Suppose your car's check engine light comes on, and you take it to a local mechanic who charges $100 to diagnose the problem. However, the mechanic fails to identify the root cause of the issue, and you end up having to pay $500 for unnecessary repairs.

Prosthetic liners made of solid elastomer like silicone, copolymer gel, or polyurethane have been commercially available and used for a number of years as the media next to the skin in the majority of lower extremity prostheses.
Such liners have solved many issues like friction and pressure distribution; however, it has been difficult to achieve effective heat and sweat management when using a non-porous interface. For instance, moisture (e.g. sweat or condensation) within the liner can adversely affect limb health. Moisture decreases the friction suspending the liner on the residual limb. This can cause a pistoning action, which describes the relative movement between the liner and the residual limb.
Excessive limb pistoning tends to lead to friction-related injuries such as friction blisters and skin irritation. It also creates the potential for catastrophic failure of the suspension of the limb. Problems such as dermatitis and infection are also common, particularly if the liner and residual limb are not cleaned appropriately or frequently.
Attempts have been made to incorporate elements such as drain systems, heat exchangers, and semiconductors into known liners and/or prostheses to more effectively remove heat and sweat from the liner interface, yet, such designs are relatively complex, bulky, costly, and inevitably prohibit their use with a large majority of users.
To prevent such problems and to maintain secure adherence, users or amputees are currently required to manage the build-up of sweat in the liner themselves. They regularly have to remove their prosthesis to empty accumulated sweat and dry their limb.
There is thus a need for a prosthetic socket system that provides simple, comfortable, and effective heat and moisture management without removal of components of the system.

textbook:
Lesson: Prosthetic Liners and Heat Management

Introduction:
Prosthetic liners are an essential component of lower extremity prostheses. They provide a comfortable interface between the user's residual limb and the prosthetic device. However, managing heat and sweat is a significant challenge when using non-porous liners. This lesson will discuss the importance of effective heat and sweat management in prosthetic liners and the challenges associated with it.

Section 1: Importance of Heat and Sweat Management
- Heat and sweat management is crucial in prosthetic liners because excessive moisture can lead to friction-related injuries, skin irritation, and other problems.
- Proper heat and sweat management can improve the comfort and usability of prosthetic devices, leading to better overall outcomes for users.

Section 2: Challenges Associated with Non-Porous Liners
- Non-porous liners do not allow for air circulation or moisture evaporation, which can lead to a buildup of moisture within the liner.
- This buildup of moisture can cause the liner to become slippery, leading to pistoning action and potential for catastrophic failure of the suspension of the limb.
- Additionally, excessive moisture can cause skin irritation and increase the risk of dermatitis and infection.

Section 3: Solutions for Effective Heat and Sweat Management
- Porous liners with micro-ventilation channels can allow for air circulation and moisture evaporation, reducing the risk of pistoning and other problems associated with excessive moisture.
- Some manufacturers have developed specialized materials that can better manage heat and sweat, such as hydrophobic coatings that repel moisture and allow for easier cleaning.
- Users can also take steps to manage heat and sweat by regularly cleaning and drying their prosthetic devices and using appropriate skin care products to prevent irritation.

Conclusion:
Effective heat and sweat management is essential for the comfort and safety of prosthetic users. Non-porous liners can present challenges in this regard, but there are solutions available that can improve the performance of prosthetic devices. By understanding the importance of heat and sweat management and the challenges associated with non-porous liners, users can make informed decisions about the best options for their needs.

Diagnosis of public programs focused on herbal medicines in Brazil.
The present study is aimed to diagnose the current public programs focused on herbal medicines in Brazil by means of in loco visits to 10 programs selected by means of questionnaires sent to 124 municipalities that count on herbal medicine services. The main purpose of the implementation of program programs is related to the development of medicinal herbs. 70% of them are intended for the production of herbal medicines and 50% are aimed to ensure the access of the population to medicinal plants and or herbal medicines. The initiative of the implementation of these programs was related to the managers (60%). The difficulties in this implementation were due to the lack of funding (100%) of the programs. In 60% of the programs, the physicians did not adhere to herbal medicine services due to the lack of knowledge of the subject. Training courses were proposed (80%) to increase the adhesion of prescribers to the system. Some municipalities use information obtained from patients to assess the therapeutic efficiency of medicinal plants and herbal medicines. Of the programs underway, cultivation of medicinal plants was observed in 90% and 78% of them adopt quality control. In most programs, this control is not performed in accordance with the legal requirements. The programs focused on medicinal plants and herbal medicines implemented in Brazil face some chronic problems of infrastructure, management, operational capacity and self-sustainability, which can be directly related to the absence of a national policy on medicinal plants and herbal medicines.

The key is to get down to the root of the matter- where is this seperate self right now? I attempted to employ remedies "on top" of this apparent problem of seperation, rather than dig down under it and expose it directly.. Holding back a sneeze won't cure a cold- screwing around with these pointers won't be very liberating. This needs to be looked into and seen directly.. that which compels us to waffle such bs is totally indifferent the successfulness of such bs...the bs is artistic just like everything else.... indifferent TO, sorry. sneezing is cathartic. Just do it into your arm, not your hand.. Lol, sounds good! BS is certainly artistic, but I got tired of my art stinking!

Lesson: Understanding Non-Duality and Advaita Vedanta Philosophy

Introduction:
Non-duality or Advaita Vedanta is a philosophy that emphasizes the oneness of all things. It teaches that there is only one reality, and everything is just a manifestation of that reality. In this lesson, we will explore the core concepts of non-duality and Advaita Vedanta, and learn how to apply them to our daily lives.

Section 1: Understanding Non-Duality

Topic 1: What is Non-Duality?
- Non-duality is a philosophical concept that suggests there is only one reality, and everything else is an illusion.
- It teaches that there is no separation between the self and the universe, and that everything is interconnected.
- Non-duality is often associated with Advaita Vedanta, a branch of Hinduism that emphasizes the oneness of all things.

Topic 2: The Illusion of Separation
- We often perceive the world as separate and distinct, but this is just an illusion.
- Everything is interconnected, and there is no real separation between the self and the universe.
- By understanding this, we can begin to see things as they really are and let go of our attachment to the illusion of separation.

Topic 3: The Concept of Brahman
- Brahman is the ultimate reality in Advaita Vedanta philosophy.
- It is the underlying principle that connects all things and makes them possible.
- By understanding Brahman, we can begin to see the oneness of all things and let go of our attachment to the illusion of separation.

Section 2: Applying Non-Duality to Our Daily Lives

Topic 1: Living in the Present Moment
- One of the most important aspects of non-duality is living in the present moment.
- By being fully present, we can experience the oneness of all things and let go of our attachment to the past or future.
- This can be achieved through mindfulness practices such as meditation, yoga, or simply being fully present in each moment.

Topic 2: Letting Go of Attachment
- Another important aspect of non-duality is letting go of attachment to outcomes.
- By recognizing that everything is interconnected and nothing is truly separate, we can begin to see that our attachments are illusory.
- This can be challenging, but by practicing non-attachment, we can experience greater freedom and peace in our lives.

Topic 3: Finding Inner Peace

I'm overhauling the PTO take off shaft and housing and want to replace the bearings but have come across something I've not seen before. When I measure the bearing (main front end roller) it is 44.5 mm wide by 14mm deep with a centre of 19mm for the shaft. When I look for this size in the UK bearing suppliers charts I cannot find a match. There are also signs that there is a gap (assuming the current bearing is correct) between the bearing and the main circlip retaining the main bearing of 3.5mm.

Referring to the parts list it shows a seal of a design that cannot possibly be correct for 3.5mm.

Can anyone throw any light on what the correct bearing size should be .

The front bearing (Bolens part # 1185605) is a pretty common 6203 series bearing. You should be able to easily source a SKF 6203-ZZ bearing or equivalent. Just remove one seal to match the OEM bearing so you can grease it. Not sure that I follow you on the "gap" problem you have. Are you missing the 1721590 nylon seal washer out front? Also, the 1185649 retaining rings are not a standard hardware size. They are 0.080" thick (or 2.01mm) Here is a good look at the part diagram. Make sure that everything is installed exactly as it is shown in the diagram.

Edit for correction: Correct bearing is a 1635-2RS with one seal removed.

As ClassicBolens said, it's a common size bearing, but it's an inch-series bearing, not Metric. It should be 1.75" OD x 0.75" ID x 0.50" thick. It should have a seal on one side only, as the PTO is lubed with grease via a Zerk fitting on the side of the housing. The sealed side of the bearing should face out and the open side in.

Thanks for the replies guys. I searched the sites for the given SKF number and the sizes don't tie up plus the given assembly diagram. Based on the assembly diagram the outer nylon seal would seat on the bearing circling which from a base engineering principle cannot be true. No engineer would specify that a nylon outer seal would face against a circling.

SKF 6203 ZZ does not correlate to the required size and when I search in imperial the searches come up as not found.

HOwever all is not lost, I have found a housing seal on e bay today so just hope the P&P charges are ok. Have also rejuvenated the main bearing by soaking in penetrating oils for 24hrs and then spinning up with an air blower re cleaning and repacking with grease.

Assembly sequence and bearing dimensions still don't make any sense though !

Thanks for the replies.

My apologies. The 6203 bearing is wrong. That's what I get for going from memory (which I think is slowly fading)

The assembly goes together just as it is shown in the diagram, with the exception of the large internal retaining ring. It holds the ball bearing in place, then the seal washer goes on (heat it in boiling water to assist installation) then the 1185649 retaining ring holds it in place.

Thanks for that. I've ordered the bearing now from Simply bearings, that's who I normally use. The diagram is somewhat misleading as it indicates the large circlip goes on top of the nylon seal. I had worked it out that it could not possibly be as shown. As it happens Rick had a seal for sale so have bought that.

When I'm overseas next I'll get a load of them made as they seem quite rare.

Lesson: How to Measure Bearings and Select the Correct Replacement Parts

Introduction:
Bearings are an essential component in many machines and equipment, including lawn mowers. Knowing how to measure bearings and select the correct replacement parts is crucial for maintaining the functionality and performance of these machines. In this lesson, we will learn how to measure bearings, identify the correct replacement parts, and understand the importance of selecting the appropriate seals and retaining rings.

Section 1: How to Measure Bearings

Step 1: Identify the Bearing Type
Before measuring the bearing, you need to identify the type of bearing you have. There are two main types of bearings: radial bearings and thrust bearings. Radial bearings support radial loads, while thrust bearings support axial loads.

Step 2: Measure the Outside Diameter (OD)
Measure the outside diameter of the bearing with a micrometer or a caliper. This measurement should be taken from the edge of the inner race to the edge of the outer race.

Step 3: Measure the Inside Diameter (ID)
Measure the inside diameter of the bearing with a micrometer or a caliper. This measurement should be taken from the edge of the outer race to the edge of the inner race.

Step 4: Measure the Width
Measure the width of the bearing with a micrometer or a caliper. This measurement should be taken from one side of the bearing to the other, perpendicular to the OD and ID.

Step 5: Measure the Depth
Measure the depth of the bearing with a micrometer or a caliper. This measurement should be taken from the front face of the bearing to the rear face.

Step 6: Identify the Bearing Type Based on Measurements
Once you have measured the bearing, compare your measurements to bearing catalogs or online resources to identify the type of bearing you have.

Section 2: How to Select the Correct Replacement Parts

Step 1: Identify the Bearing Type
Determine the type of bearing you need to replace based on the machine's parts list or manual.

Step 2: Compare Measurements to Bearing Catalogs
Compare your measurements to bearing catalogs or online resources to find the correct replacement bearing. Make sure the measurements match within the tolerance range specified in the catalog.

Step 3: Choose the Appropriate Seals and Retaining Rings
In addition to the bearing, you may need to replace the seals and retaining rings. Choose the appropriate seals based on the bearing type and the machine's parts list or manual. Retaining rings should be chosen based on their thickness and compatibility with the bearing and machine.

Section 3: Importance of Selecting the Appropriate Seals and Retaining Rings

Seals and retaining rings are essential components of bearings that help to maintain the integrity of the bearing and the machine. Properly selected seals and retaining rings can prevent contamination, ensure proper lubrication, and prevent the bearing from slipping or falling out of place. Failure to select the appropriate seals and retaining rings can lead to premature bearing failure, which can cause damage to the machine and pose a safety risk.

Conclusion:
In this lesson, we learned how to measure bearings and select the correct replacement parts. We also discussed the importance of selecting the appropriate seals and retaining rings. By following these steps, we can ensure that our machines operate efficiently and safely.

Lesson: Understanding Internet Protocol (IP) Addresses

Introduction:
An Internet Protocol (IP) address is a unique numerical label assigned to every device participating in a computer network that uses the Internet Protocol for communication. In this lesson, we will learn about IP addresses, their importance, and how they work.

Section 1: Theoretical Concepts

**What is an IP address?**
An IP address is a numerical label assigned to every device participating in a computer network that uses the Internet Protocol for communication. It serves two principal functions: host or network interface identification and location addressing.

**Why are IP addresses important?**
IP addresses are essential because they allow devices to communicate with each other over the internet. Without IP addresses, devices would not be able to locate and communicate with one another, making it impossible to share information or access resources on the internet.

Section 2: Practical Examples

**How does an IP address work?**
When you send data over the internet, the data is broken into small packets. Each packet contains the sender's IP address, the recipient's IP address, and the data being sent. The packets are then sent to the recipient's IP address, where they are reassembled and processed.

**What are some examples of IP addresses?**
There are two types of IP addresses: IPv4 and IPv6. An example of an IPv4 address is 192.168.1.1, while an example of an IPv6 address is 2001:db8:0:1234:0:567:8:1.

Section 3: Self-Debating Discussions

**Is it possible to have multiple IP addresses?**
Yes, it is possible to have multiple IP addresses. For example, when using a home router, each device connected to the router will have its own unique IP address.

**Can IP addresses be blocked?**
Yes, IP addresses can be blocked by firewalls or other security measures. This can prevent unauthorized access to a network or website.

Conclusion:
In this lesson, we learned about IP addresses, their importance, and how they work. We also explored practical examples and self-debating discussions to deepen our understanding of this topic. By mastering these concepts, we can apply them to new problems and further explore the world of computer networking.
