Lesson: Introduction to Polishing Granite

## Section 1: Theoretical Concepts
Polishing granite is the process of smoothing and shining the surface of the stone to make it look more attractive and durable. It involves the use of abrasives, which are materials that are harder than the stone but softer than diamonds, to remove small particles from the surface of the granite.

## Section 2: Practical Examples
One type of abrasive used for polishing granite is called Quasar. This abrasive is made from industrial diamonds and a highly resistant mechanical and thermic resin. The combination of these two materials allows for an excellent working removal capacity and low consumption of abrasives while polishing granite.

There are several different grades of Quasar abrasive available, ranging from 120 to 3000. The grade refers to the size of the abrasive particles, with lower numbers representing finer particles and higher numbers representing coarser particles. A common sequence of grades used when polishing granite is 120, 220, 320, 400, 600, 800, 1200, 1500, 2000, and 3000.

Another type of abrasive used for polishing granite is called Abra Iride. This abrasive is available in a variety of brushes for marble and granite, as well as DIAMOND IRINEX, which has diamond filaments. Abra Iride offers a wide range of brush sizes, including 24, 36, 46, 60, 80, 120, 180, 240, 320, 500, 600, 800, 1000.

## Section 3: Self-Debating Discussions
Using abrasives like Quasar and Abra Iride can help polish granite to a high gloss. The special composition of these abrasives ensures that the final polish is of the highest quality. However, there are other factors to consider when polishing granite, such as the type of granite being polished and the desired level of gloss.

In some cases, it may be necessary to use a series of different grades of abrasives to achieve the desired level of polish. For example, starting with a coarser grade of abrasive, such as 120 or 220, can help remove larger particles from the surface of the granite. Then, a finer grade of abrasive, such as 320 or 400, can be used to refine the surface and remove smaller particles. Finally, a very fine grade of abrasive, such as 600 or 800, can be used to achieve a high gloss polish.

## Glossary
- Abrasive: A material that is harder than the stone but softer than diamonds, used to remove small particles from the surface of the granite.
- Grade: A measure of the size of the abrasive particles, with lower numbers representing finer particles and higher numbers representing coarser particles.
- Polishing: The process of smoothing and shining the surface of the granite to make it look more attractive and durable.
- Resin: A substance used to bind the abrasive particles together in an abrasive product.

This lesson has provided you with the necessary knowledge to understand these business practices and apply them to real-world scenarios.


text: Hi Everyone,. Today I was happy to see the Red Sox's play again, especially I got to see Jason Varitek!!. He is so handsome! But I was sad to see how Dice K performed. What is up with that? I thought this year he would be more settled in, but as much as we hype him up, he always fails. I don't know what to think, we will just have to see how this year goes for him. I also felt sad because I could not talk to my mom about the Red Sox's. She loved watching them. Jimmy got her into many sports. She liked golf, and liked Tiger Woods, she liked the Patriots. I must say though she smiled the most talking about the Red Sox's. Last year she was so excited about the new pitcher Dice K. My Aunt Kay, my mothers sister called last week to see how we were all doing through her birthday. I told her we all did pretty good. She said she had a dream the other night of my mother. She was wearing all white. I knew what that meant. She then said to me, that means she is an Angel. I said you are right :). Take Care,. Janet

Lesson: Core Value - Dreams and Interpretation

Introduction:
Dreams have been a part of human culture for centuries. They are a reflection of our inner thoughts, emotions, and desires. In this lesson, we will explore the meaning behind dreams and how to interpret them.

Section 1: Understanding Dreams

Topic 1: What are dreams?
Dreams are a series of thoughts, images, sensations, or stories that occur during sleep. They are involuntary and can be influenced by our daily experiences, emotions, and memories.

Topic 2: Why do we dream?
The exact reason why we dream is still unknown, but there are several theories. Some scientists believe that dreams help us process emotions and consolidate memories. Others think that dreams are a way for our brain to communicate with us.

Topic 3: Types of dreams
There are two types of dreams: rapid eye movement (REM) sleep and non-REM sleep. REM sleep is when most dreaming occurs, while non-REM sleep is when we experience deeper sleep and feel restful.

Topic 4: Dream symbols
Dreams often contain symbols that can have different meanings depending on the context. For example, a dream about a snake can represent fear or temptation, while a dream about water can symbolize emotions or renewal.

Section 2: Interpreting Dreams

Discolouration in potable water distribution systems: a review.
A large proportion of the customer contacts that drinking water supply companies receive stem from the occurrence of discoloured water. Currently, such complaints are dealt with in a reactive manner. However, water companies are being driven to implement planned activities to control discolouration prior to contacts occurring. Hence improved understanding of the dominant processes and predictive and management tools are needed. The material responsible for discolouration has a variety of origins and a range of processes and mechanisms may be associated with its accumulation within distribution systems. Irrespective of material origins, accumulation processes and mechanisms, discolouration events occur as a result of systems changes leading to mobilisation of the accumulations from within the network. Despite this conceptual understanding, there are very few published practicable tools and techniques available to aid water companies in the planned management and control of discolouration problems. Two recently developed and published, but different approaches to address this are reviewed here: the PODDS model which was developed to predict levels of turbidity as a result of change in hydraulic conditions, but which is semi-empirical and requires calibration; and the resuspension potential method which was developed to directly measure discolouration resulting from a controlled change in hydraulic conditions, providing a direct assessment of discolouration risk, although intrinsically requiring the limited generation of discoloured water within a live network. Both these methods support decision making on the need for maintenance operations. While risk evaluation and implementation of appropriate maintenance can be implemented to control discolouration risk, new material will continue to accumulate and hence an ongoing programme of maintenance is required. One sustainable measure to prevent such re-accumulation of material is the adoption of a self-cleaning threshold, an hydraulic force which a pipe experiences on a regular basis that effectively prevents the accumulation of material. This concept has been effectively employed for the design of new networks in the Netherlands. Alternatively, measures could be implemented to limit or prevent particles from entering or being generated within the network, such as by improving treatment or preventing the formation of corrosion by-products through lining or replacing ferrous pipes. The cost benefit of such capex investment or ongoing opex is uncertain as the quantification and relative significance of factors possibly leading to material accumulation are poorly understood. Hence, this is an area in need of significant further practical research and development.

Lesson: Discolouration in Potable Water Distribution Systems

**Introduction:**
Discolouration in potable water distribution systems is a common problem that many people face. It occurs when the water in the system becomes cloudy or has an unusual color. This can be caused by various factors, including the presence of minerals, organic matter, or other substances in the water. In this lesson, we will learn about the causes of discolouration, the processes involved, and the measures that can be taken to prevent and manage this issue.

**Section 1: Causes of Discolouration**
Discolouration in potable water distribution systems can be caused by several factors. These include:

1. Corrosion of pipes: When water sits in pipes for a long time, it can cause the pipes to corrode. This can lead to the release of metals such as iron and manganese into the water, causing it to become discolored.

2. Biofilm formation: Biofilms are communities of microorganisms that adhere to surfaces. They can form on the inside walls of pipes, and when they break off, they can cause the water to become discolored.

3. Sedimentation: Over time, sediment such as rust, sand, or dirt can accumulate in the bottom of pipes. When water flows through these pipes, the sediment can be stirred up and cause the water to become discolored.

4. Chemical reactions: Some chemicals used in water treatment can react with other substances in the water, causing discoloration.

**Section 2: Processes and Mechanisms Involved in Discolouration**
There are several processes and mechanisms involved in discolouration in potable water distribution systems. These include:

1. Mobilisation: This is the process by which accumulated material in the distribution system is released into the water. This can occur due to changes in water flow, pressure, or temperature.

2. Coagulation and flocculation: These are processes that involve the formation of larger particles from smaller ones. Coagulants and flocculants are often added to the water to promote these processes, which can help to reduce discolouration.

3. Sedimentation: This is the process by which particles settle out of the water over time. Sedimentation can help to remove some of the causes of discolouration from the water.

4. Filtration: Filtration involves the use of filters to remove particles from the water. This can help to reduce discolouration by removing some of the causes of the problem.

**Section 3: Preventing and Managing Discolouration**
There are several measures that can be taken to prevent and manage discolouration in potable water distribution systems. These include:

1. Regular flushing: Flushing the distribution system regularly can help to remove accumulated material and prevent discolouration.

2. Corrosion control: Adding chemicals to the water can help to control corrosion and reduce the release of metals into the water.

3. Biofilm control: Chemicals can be added to the water to control biofilm formation, reducing the risk of discolouration caused by broken-off biofilms.

4. Sedimentation control: Implementing measures to reduce sedimentation, such as regular cleaning of pipes, can help to prevent discolouration caused by stirred-up sediment.

5. Monitoring and testing: Regular monitoring and testing of the water quality can help to identify potential issues and take corrective action before discolouration occurs.

**Conclusion:**
In conclusion, discolouration in potable water distribution systems can be caused by various factors and involves several processes and mechanisms. By understanding these factors and processes, water companies can implement preventative measures and manage discolouration events more effectively. This will help to improve the quality of the water supplied to customers and reduce the number of customer complaints related to discoloured water.

Q:

Curiosity about a simple identity

Consider the well known formula
$$1^3 + 2^3 +\cdots+ n^3 = (1+\cdots+n)^2  , n \in N$$
Now suppose that for all $n \in N$ the identity is true :
$$1^k + 2^k +\cdots+ n^k = (1+\cdots+n)^{k-1}  $$
with $k \in N$ fixed. Which is the possible values of $k$ ?
Someone could point me a reference?
Sorry for my english, it is not good
Thanks in advance

A:

The dominant term of the left hand side is  $$ \frac{1}{k+1} n^{k+1}.  $$
The right hand side is $$  \left( \frac{n^2 + n}{2} \right)^{k-1},  $$ dominant term
$$ \frac{2}{2^k} n^{2k - 2}.  $$
So $$  k+1 = 2k - 2 $$ and
$$  3 = k $$

Lesson: Finding the Perfect Cubes

**Introduction**

In this lesson, we will learn about finding perfect cubes. A perfect cube is a number that can be expressed as the cube of an integer. We will use mathematical abstractions and real-world scenarios to understand the concept of perfect cubes.

**Section 1: Theoretical Concepts**

A cube is a number that is raised to the power of 3. For example, 8 is a cube because 8^3 = 512. A perfect cube is a number that can be expressed as the cube of an integer. For example, 16 is a perfect cube because 16^3 = 4096, which is the cube of 12.

**Section 2: Practical Examples**

We can use the formula for finding perfect cubes to solve problems. For example, if we want to find the smallest number that is not a perfect cube, we can subtract 1 from the largest possible cube and check if it is divisible by 3. If it is not, then the smallest number that is not a perfect cube is the next whole number.

**Section 3: Real-World Scenarios**

Perfect cubes are used in many real-world scenarios, such as in sports where the distance traveled is measured in meters, centimeters, or millimeters. In finance, perfect cubes are used to calculate interest on loans. In computer science, perfect cubes are used to optimize algorithms.

Q:

How to use 'debugger' and 'pry' when developing a gem? (Ruby)

I'm developing a gem, and my Gemfile looks like this:
source :rubygems

gemspec

group :development, :test do
  gem "pry"
  gem "debugger"
  gem "rake"
end

However, I don't want people to have to install pry and debugger when running tests, but I also want to be able to require them in my tests (because I'm running tests prefixed with bundle exec, and I cannot get it them in my load path if they're not in the Gemfile). How do I achieve this?
Also, when to put gems that I use for development in the gemspec, and when to put them in the Gemfile? I really don't know the difference.

A:

You can add gems to your gemspec as a development dependency, like this:
Gem::Specification.new do |s|
  # ...
  s.add_development_dependency 'pry'
  s.add_development_dependency 'debugger'
  s.add_development_dependency 'rake'
end

These will only be installed when working on the gem and not when installing the gem itself.

A:

Just as @andrew-vit said, you can add it to your gem specifications as a development dependency
Gem::Specification.new do |spec|
   #...
   spec.add_development_dependency "pry"
   spec.add_development_dependency "debugger"
   #...
end

Since this will be a development dependency, you don't want to add require 'pry' into your main gem app, so just add it into your spec_helper.rb or whatever your test setup file is.
require 'rspec'
require 'vcr'
require 'pry'
#...

Then when you run your specs, you can still add your binding.pry into the code for your sandbox. Make sure your specs run before pushing your code. That way if it breaks, you'll see you forgot a breakpoint in your code.

Lesson: How to Use CakePHP to Filter Data Based on Selected Field Values

Introduction:
In this lesson, we will learn how to use CakePHP to filter data based on selected field values. We will use the example provided in the input question to demonstrate this concept.

Section 1: Understanding the Problem
The problem we are trying to solve is how to get all the values in a row when a specific checkbox is selected. We want to achieve this without sending all the data through AJAX.

Section 2: Setting up the View
In our view, we will create a form with checkboxes for each program. We will also add a button to submit the form.

```html
<form>
    <?php foreach ($programs as $program): ?>
        <input type="checkbox" name="<?php echo $program['t_fm_program_id']; ?>" value="<?php echo $program['number_of_time']; ?>">
    <?php endforeach; ?>
    <button type="submit">Submit</button>
</form>
```

Section 3: Writing the Controller Function
In our controller function, we will check if the form has been submitted. If it has, we will loop through each program and check if its corresponding checkbox is selected. If it is, we will output all the values in that row.

```php
public function filterData() {
    if ($this->request->is('post')) {
        $selectedPrograms = $this->request->data();
        foreach ($selectedPrograms as $programId => $selected) {
            if ($selected) {
                $program = $this->Programs->find('first', ['conditions' => ['t_fm_program_id = ' . $programId]]);
                echo $program['number_of_time'] . '<br>';
            }
        }
    }
}
```

Section 4: Adding the Function to the Router
We will add the `filterData()` function to the router so that it can be accessed via a URL.

```php
$this->RouteRegex->connect('/filter-data/*', ['controller' => 'programs', 'action' => 'filterData']);
```

Section 5: Testing the Function
Now that we have set up the view, controller, and router, we can test the function by submitting the form. When we select the checkbox for program ID 42, we should see the number of times it appears in the output.

Conclusion:
In this lesson, we learned how to use CakePHP to filter data based on selected field values. We created a form with checkboxes for each program, wrote a controller function to check if the form had been submitted and loop through each program, and added the function to the router so that it could be accessed via a URL. Finally, we tested the function by selecting the checkbox for program ID 42 and saw the number of times it appeared in the output.

2011 Chatham Cup

The 2011 ASB Chatham Cup is New Zealand's 84th knockout football competition.

The 2011 competition had a preliminary round, a qualification round, and four rounds proper before quarter-finals, semi-finals, and a final. Competition was run in three regions (northern, central, southern) until the quarter-finals, from which stage the draw was open. In all, 120 teams entered the competition.

The 2011 final
With both finalists coming from the lower North Island, it was decided by NZF to hold the final at a neutral venue in the same part of the country. As such, Palmerston North's Memorial Park played host to the final for the first time.

The final was played in front of a crowd of some 3,000 spectators. Underdogs Wairarapa won the final largely through their Pacific Island combination of Seule Soromon and Pita Rabo. They took the lead in the 24th minute after a period of pressure,  when striker Soromon latched onto a cross from right winger Dale Higham, heading the ball past Hawke's Bay goalkeeper Shaun Peta. Early in the second half, Wairarapa failed to double the lead, when a penalty taken by their captain Adam Cowan hit the woodwork. Napier came back strongly, scoring an equaliser through Fergus Neil in the 67th minute. From this point, however, the game was largely under Wairarapa's control, and a late goal from Rabo secured the win.

The Jack Batty Memorial Cup for the final's most valuable player was awarded to Wairarapa's Scott Robinson.

Lesson: Understanding Semiconductor Lasers

Introduction:
Semiconductor lasers are devices that emit light when electrical current passes through a semiconductor material. They are used in various applications such as optical communication systems, barcode readers, and medical equipment. In this lesson, we will learn about the basic principles of semiconductor lasers and their frequency stabilization.

Section 1: Basic Principles of Semiconductor Lasers

Topic 1: What is a Semiconductor Laser?
A semiconductor laser is a type of laser that uses a semiconductor material as its gain medium. The most common semiconductor materials are gallium arsenide (GaAs) and indium phosphide (InP). These materials have unique properties that allow them to emit light when an electric current passes through them.

Topic 2: How does a Semiconductor Laser Work?
When an electric current passes through a semiconductor material, it excites the electrons in the material. These excited electrons then recombine with holes in the material, releasing energy in the form of photons. The photons travel through the material and are emitted as a coherent beam of light. This process is called stimulated emission, and it is the basis for how all lasers work.

Topic 3: Types of Semiconductor Lasers
There are two main types of semiconductor lasers: direct bandgap and indirect bandgap. Direct bandgap lasers have a bandgap that allows them to emit light at room temperature, while indirect bandgap lasers require a higher energy to emit light. The most common type of semiconductor laser is the direct bandgap laser.

Section 2: Frequency Stabilization of Semiconductor Lasers

Topic 1: Why is Frequency Stabilization Important?
Frequency stabilization is important because it ensures that the laser emits light at a consistent wavelength. This is necessary for many applications, such as optical communication systems, where precise timing and wavelength control are required.

Topic 2: How is Frequency Stabilization Achieved?
Frequency stabilization can be achieved by locking the laser's frequency to an external reference source, such as an atomic clock or a cavity. This is done by comparing the laser's frequency to the reference source and adjusting the laser's current until the frequencies match.

Topic 3: Example of Frequency Stabilization
An example of frequency stabilization is the locking of a single-mode GaAlAs semiconductor laser operating at around 830 nm to the center of an absorption line of molecular iodine vapor. A relative frequency stability of better than 10^-9 was obtained for time periods longer than 1 s.

Conclusion:
In this lesson, we learned about the basic principles of semiconductor lasers and their frequency stabilization. We discussed what a semiconductor laser is, how it works, and the importance of frequency stabilization. We also explored the different types of semiconductor lasers and how frequency stabilization is achieved. By understanding these concepts, we can apply our knowledge to other areas of physics and engineering.

Glossary:
- Chemical elements: The fundamental building blocks of matter that cannot be broken down using chemical means.
- Semiconductor lasers: Lasers that use a semiconductor material as their gain medium.
- Absorption line: A spectral line that results from the absorption of light by a substance.
- Wavelength: The distance between two points on a wave that are in phase.
- Frequency: The number of oscillations of a wave per unit time.

Lesson: Understanding Genuine Parts and Consumables

Introduction:
In today's world, we rely on various machines and appliances to make our lives easier. These machines need maintenance and repair from time to time to ensure they function correctly. One way to ensure that our machines function correctly is by using genuine parts and consumables. In this lesson, we will learn about what genuine parts and consumables are, why they are essential, and how to identify them.

Section 1: What are Genuine Parts and Consumables?
Genuine parts and consumables refer to components or materials that are specifically designed and manufactured for a particular machine or appliance. These parts and consumables are made to meet the exact specifications of the machine, ensuring optimal performance and safety.

Why are Genuine Parts and Consumables Important?
Using genuine parts and consumables is crucial because they are specifically designed to work with your machine or appliance. They are made to fit perfectly, ensuring that your machine operates smoothly and efficiently. Additionally, genuine parts and consumables are made from high-quality materials that can withstand the rigors of daily use. Using non-genuine parts and consumables may result in poor performance, damage to your machine, or even injury.

Section 2: Identifying Genuine Parts and Consumables
Identifying genuine parts and consumables can be challenging, especially when shopping online or at a store where you don't know the products. However, there are some ways to identify genuine parts and consumables:

1. Look for the manufacturer's logo or brand name on the packaging or product.
2. Check the product's description for information about its compatibility with your machine or appliance.
3. Compare the price of the product to similar products. If the price seems too good to be true, it may be a counterfeit product.
4. Read reviews from other customers who have purchased the product. If many customers report issues with the product, it may not be genuine.

Section 3: Real-World Examples
Let's consider a few examples to see how genuine parts and consumables play a role in maintaining our machines and appliances:

Example 1: Coffee Maker
If you own a DeLonghi coffee maker, using genuine parts and consumables is essential to ensure that your coffee maker functions correctly. For instance, if the pump in your coffee maker breaks down, you need to replace it with a genuine DeLonghi pump to ensure that it fits correctly and works efficiently.

Example 2: Iron
Suppose you have a DeLonghi iron, and you notice that the steam output has decreased significantly. In that case, it could be due to a clogged resin filter. Instead of trying to fix the issue yourself, you should replace the filter with a genuine DeLonghi anti-scale resin filter to ensure that the problem is resolved effectively.

Conclusion:
In conclusion, using genuine parts and consumables is crucial for maintaining the functionality and safety of our machines and appliances. By identifying genuine parts and consumables and using them in our machines, we can ensure that they operate correctly and last longer. We hope that this lesson has been helpful in teaching you about genuine parts and consumables and how to identify them.

Glossary:
- Genuine Parts: Components or materials specifically designed and manufactured for a particular machine or appliance.
- Consumables: Materials or supplies used up or depleted during the operation of a machine or appliance.
- Counterfeit Product: A product that is imitation or fake, often created to look like the genuine article.
