Catholic News Service

Catholic News Service (CNS) is an American news agency that reports on the Roman Catholic Church. CNS was established in 1920 as the National Catholic Welfare Council (NCWC) Press Department.  In the 1960s it became the National Catholic News Service, and dropped "National" from its name in 1986 to indicate its intention to provide worldwide coverage.

CNS describes itself as the primary source of national and global news that the US Catholic press reports. It is editorially independent and a financially self-sustaining division of the US Conference of Catholic Bishops. It is based in Washington, DC, United States.

The documentary service of CNS, Origins "publishes texts from the Vatican, [P]ope, bishops, Congress, Senate, Supreme Court and church leaders around the world".

From 2004 to 2016, Tony Spence led CNS as its director and editor-in-chief. He was removed in April 2016 after some conservative Catholics criticized his posts on Twitter that favored LGBT rights.

Lesson: The Importance of Independent Journalism

Introduction:
Journalism plays a crucial role in society by providing information to the public. However, not all journalism is created equal. In this lesson, we will explore the importance of independent journalism and why it is essential for a healthy democracy.

Section 1: What is Independent Journalism?
Independent journalism refers to the practice of reporting news events without any influence or control from government, corporations, or other powerful entities. It is vital because it allows for unbiased reporting and helps maintain a free and open society.

Section 2: Why is Independent Journalism Important?
Independent journalism is crucial because it provides citizens with the information they need to make informed decisions about their government and society. Without independent journalism, powerful entities can manipulate the news to serve their interests, leading to a lack of transparency and accountability.

Section 3: How does Independent Journalism benefit society?
Independent journalism benefits society by holding those in power accountable for their actions. It also provides a platform for marginalized voices to be heard and promotes a diverse range of opinions. This leads to a more informed and engaged citizenry, which is essential for a healthy democracy.

Section 4: Examples of Independent Journalism
One example of independent journalism is the Washington Post's coverage of the Watergate scandal. The Post's reporting on the scandal ultimately led to President Nixon's resignation. Another example is the work of investigative journalists who expose corruption and wrongdoing in government and business.

Conclusion:
Independent journalism is essential for a healthy democracy. It allows for unbiased reporting and helps maintain a free and open society. By providing citizens with the information they need to make informed decisions, independent journalism holds those in power accountable and promotes a more engaged citizenry. As future leaders, it is crucial that we support and advocate for independent journalism.

Glossary:
- Independent Journalism: Journalism that is not controlled or influenced by any powerful entity.
- Accountability: The ability of individuals or organizations to answer for their actions; the quality of being able to give an account of one's actions.
- Democracy: A system of government where power is held by the people, either directly or through elected representatives.

Is There a Better Way to Farm Fish?. Aquaculture is a huge industry. In 2014, for the first time, more than half of all seafood consumed by humans came from fish farms, with salmon among the most farmed species. But aquaculture is also contentious — in large part because of the problems with existing open-net pens. Yet Jeremy Dunn, executive director of the BC Salmon Farmers Association, says the industry is already starting to move away from open-net pens. While Dunn says 90 per cent of new investment globally is in variations on the technology, leading salmon-farming countries such as Norway are investing in hitherto unfeasible technologies, such as land-based tanks and recirculating aquaculture systems. click here to read the story 10:54

Lesson: How to Identify and Mitigate Environmental Impacts of Fish Farming

Introduction:
Aquaculture, or fish farming, is a rapidly growing industry that provides a significant portion of the world's seafood. However, it also has environmental impacts that must be addressed to ensure sustainability. This lesson will explore the challenges associated with fish farming and provide strategies for mitigating these impacts.

Section 1: Understanding the Environmental Impacts of Fish Farming

Topic 1: Waste and Pollution
Aquaculture can generate significant amounts of waste and pollution. This can lead to problems with water quality, harming wild fish populations, and contributing to the spread of disease.

Topic 2: Use of Antibiotics and Chemicals
Fish farming often relies on the use of antibiotics and other chemicals to prevent disease and promote growth. This can lead to the development of drug-resistant bacteria and contamination of the environment.

Topic 3: Habitat Destruction
The construction of fish farms can lead to habitat destruction, particularly in areas where wild fish populations are already vulnerable.

Section 2: Strategies for Mitigating Environmental Impacts

Topic 1: Improved Waste Management
Implementing better waste management practices can help reduce the amount of waste generated by fish farming operations. This includes using more efficient feed and reducing the amount of uneaten food that ends up in the water.

Topic 2: Alternative Treatment Methods
Exploring alternative treatment methods, such as using probiotics or other natural substances, can help reduce the reliance on antibiotics and chemicals.

Topic 3: Sustainable Site Selection
Choosing locations for fish farms that are less likely to harm wild fish populations or disrupt habitats can help minimize the environmental impact of the industry.

Section 3: Real-World Examples

One example of a company working to address the environmental impacts of fish farming is AquaBounty, which has developed genetically modified salmon that grow faster and require less feed. By using this technology, the company hopes to reduce the overall environmental footprint of its operations.

Conclusion:
By understanding the environmental impacts of fish farming and implementing strategies to mitigate them, the industry can continue to grow while also protecting the planet's resources. By applying the principles learned in this lesson, students can contribute to the development of more sustainable fish farming practices.

Glossary:
- Aquaculture: the practice of raising fish and other aquatic animals in controlled environments, such as ponds or tanks
- Open-net pen: a type of fish farm that uses nets to contain the fish, allowing them to swim in and out of the pen
- Recirculating aquaculture system (RAS): a closed system that circulates water through filters and other treatments to maintain water quality
- Probiotics: live microorganisms that, when administered in adequate amounts, confer a health benefit on the host

Synthesis and mass spectrometric characterization of a metal-affinity decapeptide: copper-induced conformational changes.
A decapeptide with high affinity toward heavy metal ions (RCHQYHHNRE) has been prepared by Fmoc strategy using TGR resin as solid support. The model peptide provides a simple system that can be used for a systematic study of the impact of different metal ions on peptide secondary structure on a molecular level; histidine residues were incorporated into the peptide in a sequence similar to beta-amyloid peptide (Abeta1-40) to generate possible complexation sites for Cu (2+) ions. The peptide secondary structure, as investigated by circular dichroism, and self-assembled nanostructures were observed to depend strongly on the presence of copper and sodium dodecyl sulfate (SDS). Atomic force microscopy (AFM) revealed also that copper and SDS affected slightly the Abeta1-40 nanostructures. An explanation for the effect of metal ions and SDS on the self-assembly of peptides was proposed. The extensive beta-sheet formation may further promote peptide self-assembly into longer fibers.

Q:

Regarding 'for' loop in KornShell

Is there a way to implement the following using 'for' in KornShell (ksh)?
Here is the C equivalent:
for(i=1;i<20;i++)
{
    printf("%d",i);
}

I was wondering if this can be implemented using just 'for' and not 'while'
I tried the following, it does not seem to work.
for i in [1-20]
    do

    print $i
    done

Please let me know your ideas and solutions.

A:

Not really an answer, but an FYI to casual ksh users.
Edit 2019-05-12 (Minor edits below in bold, other info is now stricken).
To clarify on several comments here, there are 2 ksh's available in typical vendor installations (non-Linux (maybe them too?)).
Solaris and AIX have a ksh and ksh93 (probably true for other vendors too). The base ksh is also known as ksh88. Ksh93 is described in The New Kornshell Command and Programming Language, 1995
Linux systems that have a true ksh (not pdksh), mostly use ksh93 named as ksh.
Finally, to further confuse things, don't let the 1995 pub date trick you, ksh continues under was under active development by David Korn and Glen Fowler at AT&T until 2012?. Versions were released 2-3X per year. Some Linux versions pick up the newer versions.
These newer versions have very advanced features
(most of this taken from AT&T research UWIN page. search for the link 'notes and changes'  (dead link) )

compound variables composed like c structs (no c datatypes, just typeset decls) (one user claims a 500 Meg in-memory struct)
Double precision floating point arithmetic with full C99 arithmetic ..The numbers Inf and NaN can be used in arithmetic expressions.
TAB-TAB completion generates a numbered list of completions ...
Support for processing/handling multibyte locales (e.g., en_US.UTF-8, hi_IN.UTF-8, ja_JP.eucJP, zh_CN.GB18030, zh_TW.BIG5 etc.) ...
/dev/(tcp|udp|sctp)/host/sevrice now handles IPv6 addresses ...
... seek on a file by offset or content with new redirection operators.
A new --showme option which allows portions of a script to behave as if -x were specified while other parts execute as usual. ...
The [[...]] operator =~ has been added which compares the string to an extended regular expression ....
The printf(1) builtin has been extended to support the = flag for centering a field ... (and others) ...
view-pathing
"Most of the utilities were developed by AT&T and conform to POSIX.2 and X/Open."

(note that ...s in above, usually indicate some qualifying information removed)
Korn and Fowler had also produced an advanced environment, UWIN (Unix for Windows) for people that use systems like Mingw or Cygwin, that would be worthy of a separate post. The downside for UWIN is,

not same set of utilities as you find in your favorite Linux.
Another file compilation environment that pretty much has to use MS Visual C (gcc support via Mingw is said to be on-the-way),
a very small support community,
the AT&T Common Public License V 1.0 Eclipse Public License* is not GNU.

See UWin main page  (dead link) : unfortunately out of date, better to nose around in the dnld link above. Hmm, this is much better Glenn Fowler's FAQ for UWin (also dead, Time Machine anyone?).
I hope this helps!
Edit 2019-05-12 . The reason for the dead links?
David Korn and Glen Fowler Laid Off (at AT&T, 2012?
Information later surfaced that they are working at Google. I can't confirm this, so consider it as an old rumor.
AND see Is Ksh93 dead?
There still seems to be some activity at the ast git-hub site . ast is the over-arching package that includes ksh93. You can get the fresh source code there and compile it.

Here is the text of the project description. (There is considerably more information in the README.md).

KSH93
This repository contains the AT&T Software Technology (AST) toolkit
  from AT&T Research. As of November 2017 the development focus has been
  shifted to the ksh (or ksh93) command and supporting code required to
  build it.
The non-ksh code of the AST project is no longer being actively
  maintained. If you are interested in the non-ksh code see below for
  details on which branches contain the full AST code base.
The project only supports systems where the compiler and underlying
  hardware is ASCII compatible. This includes Linux on IBM zSeries but
  not z/OS. The nascent, incomplete, support for EBCDIC has been
  removed. See issue #742.

*
The EPL replaced AT&T's original CPL.

A:

Unfortunately, it looks as if ksh does not have support for range-based brace expansion or support the (( )) construct so to do this compactly, you'll need to call the external binary seq like so:
for i in $(seq 1 20); do
  echo $i
done

A:

ksh93 supports the C-like (( ...;...; ...)):
for ((i=1;i<20;i+=1)); do
    printf "%d " $i
done && print

This will produce:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
Heck, even the old syntax (using '{' ... '}' instead of 'do ... done' will work):
for((i=1;i<20;i+=1))
{
   printf "%d " $i
} && print

In older shells, you can still get the same effect with
i=1 && while ((i<20)); do
    printf "%d " $i
    ((i+=1))
done && print

Sure, here is a self-taught lesson on implementing a 'for' loop in KornShell (ksh) to print numbers from 1 to 20:
## Lesson: Implementing a 'for' loop in KornShell (ksh) to print numbers from 1 to 20
### Introduction
In this lesson, we will learn how to implement a 'for' loop in KornShell (ksh) to print numbers from 1 to 20. We will cover the following sections:
1. Theoretical Concepts
2. Practical Examples
3. Self-Debating Discussions
4. Glossary
### Theoretical Concepts
In KornShell (ksh), we can use a 'for' loop to iterate over a range of values. The syntax for a 'for' loop in KornShell (ksh) is as follows:
```
for variable in [expression1;expression2]
    do
        command
    done
```
In our case, we want to print the numbers from 1 to 20. We can use the following 'for' loop to achieve this:
```
for i in {1..20}
    do
        echo $i
    done
```
In this example, `i` is the variable that we will use to iterate over the range of values from 1 to 20. The `in` operator specifies the range of values that we want to iterate over. In this case, we are using the `in` operator with the expression `{1..20}`, which means that we want to iterate over the numbers from 1 to 20 (inclusive).
The `do` keyword starts the body of the loop, and the `done` keyword ends the body of the loop. Inside the body of the loop, we can use the `echo` command to print the current value of `i`.
### Practical Examples
Let's see how we can use the `for` loop to print the numbers from 1 to 20:
```
$ ksh
ksh> for i in {1..20}
>     do
>         echo $i
>     done
>
1
2
3
4
5
...
18
19
20
```
In this example, we are using the `for` loop to iterate over the numbers from 1 to 20. For each iteration, we are printing the current value of `i` using the `echo` command.
### Self-Debating Discussions
One advantage of using a 'for' loop to print numbers is that it allows us to easily change the range of values that we want to iterate over. For example, if we want to print the numbers from 1 to 100, we can simply change the expression inside the `in` operator to `{1..100}`.
Another advantage of using a 'for' loop is that it allows us to perform operations on the current value of `i` in each iteration. For example, we can add 1 to `i` in each iteration to print the square of the numbers:
```
for i in {1..20}
    do
        echo $((i*i))
        i=$((i+1))
    done
```
In this example, we are adding 1 to `i` in each iteration using the `$((i+1))` syntax. We are then using the `echo` command to print the square of the current value of `i`.
### Glossary
- `for` loop: a loop in KornShell (ksh) that allows us to iterate over a range of values.
- `in` operator: an operator in KornShell (ksh) that specifies the range of values that we want to iterate over.
- `done`: a keyword in KornShell (ksh) that ends the body of the loop.
- `echo`: a command in KornShell (ksh) that prints the specified string to the standard output.
- `$((expression))`: an expression in KornShell (ksh) that evaluates to the result of the specified expression.
### Conclusion
In this lesson, we learned how to implement a 'for' loop in KornShell (ksh) to print numbers from 1 to 20. We covered the theoretical concepts, practical examples, self-debating discussions, and a glossary. We hope that you found this lesson informative and useful.

[Clinical study of 1949 cases of port wine stains treated with vascular photodynamic therapy (Gu's PDT)].
Complete fading of port wine stains (PWS) is difficult to achieve with current laser treatments. Photodynamic therapy (Gu's PDT) could offer a very efficient alternative for PWS therapy. 1949 lesions in 1385 patients were treated by PDT. Each patient received an intravenous injection of hematoporphyrin derivative (HpD) or hematoporphyrin monomethyl ether (HMME) at 3-7 mg/kg. Laser irradiation was performed on a 2 to 8 cm spot size. Different wavelengths (488.0 nm to 578.2 nm) were evaluated with a power density of 50-100 mW/cm2. Fluences ranged from 90 to 540 J/cm2. Among the 1942 lesions, PWS clearance was observed in 99.7% of cases. Excellent results were achieved in 128 lesions (6.6%) (100% clearance), 746 lesions (38.3%) yielded to good results (clearance > 75%), 923 lesions (47.4%) showed moderate results (clearance 50-75%), 145 lesions (7.4%) showed poor results (clearance<50%) and in 7 lesions (0.3%) no visible change was observed. The pink port wine stains revealed better response to Gu's PDT with only one session. Conversely, purple stains in adult patients required 2 sessions or more. This new PDT technique is effective and highly selective, with almost no risk of scarring.

Lesson: Introduction to Photodynamic Therapy for Port Wine Stains

### Overview
Photodynamic therapy (PDT) is a medical treatment that uses a combination of light and a photosensitizer to target and destroy abnormal cells. In this lesson, we will learn about PDT for port wine stains, a type of birthmark that can be challenging to treat using traditional methods.

### Objectives
By the end of this lesson, you will be able to:
- Define photodynamic therapy and its components
- Explain why PDT is an effective treatment for port wine stains
- Describe the steps involved in PDT for port wine stains
- Understand the potential benefits and risks of PDT for port wine stains

### Section 1: What is Photodynamic Therapy?
Photodynamic therapy (PDT) is a medical treatment that uses a combination of light and a photosensitizer to target and destroy abnormal cells. The photosensitizer is a special substance that is injected into the body and absorbs light at a specific wavelength. When the photosensitizer absorbs light, it produces a type of oxygen that can damage and kill nearby cancer cells.

### Section 2: Why is PDT Effective for Port Wine Stains?
Port wine stains are caused by abnormal blood vessels in the skin. These blood vessels reflect light differently than normal skin, which can make them difficult to treat with traditional methods like laser therapy. However, PDT can be an effective treatment for port wine stains because it targets the abnormal blood vessels without damaging the surrounding healthy tissue.

### Section 3: How is PDT Performed for Port Wine Stains?
The process for PDT for port wine stains involves several steps:

1. Injection: A photosensitizer is injected into the bloodstream, usually through an intravenous (IV) line in the arm.
2. Incubation: The photosensitizer is allowed to circulate in the bloodstream and accumulate in the abnormal blood vessels of the port wine stain.
3. Illumination: A special light source that emits light at a specific wavelength is shined on the port wine stain. This light activates the photosensitizer, which then produces the damaging oxygen.
4. Repeat sessions: Depending on the size and severity of the port wine stain, multiple sessions of PDT may be required to achieve the desired results.

### Section 4: Potential Benefits and Risks of PDT for Port Wine Stains
There are several potential benefits to using PDT for port wine stains, including:
- Non-invasive treatment: Unlike laser therapy, PDT does not require surgery or other invasive procedures.
- Minimal side effects: PDT has fewer side effects compared to other treatments for port wine stains.
- Customizable: The wavelength of light used in PDT can be adjusted to target different types of port wine stains.

However, there are also some potential risks associated with PDT, such as:
- Allergic reactions: Some people may experience an allergic reaction to the photosensitizer or other components of PDT.
- Skin damage: Although PDT is designed to target abnormal blood vessels, it can also damage healthy skin if not done correctly.
- Recurrence: While PDT can effectively treat port wine stains, they may return in the future.

### Conclusion
In this lesson, we learned about photodynamic therapy and its application in treating port wine stains. We discussed the components of PDT, why it is an effective treatment for port wine stains, and the steps involved in the procedure. We also explored the potential benefits and risks of PDT for port wine stains. By understanding these concepts, we can better appreciate the potential of PDT as a valuable tool in the treatment of port wine stains and other medical conditions.

Lesson: Introduction to Welding

**Objective:** To introduce students to the basics of welding and its applications.

**Materials:** None

**Vocabulary:** Welding, arc, electrode, rectifier, current, voltage, base metal, filler metal, shielding gas.

**Section 1: What is Welding?**

Welding is a process of joining two pieces of metal together by heating them to a high temperature and adding a filler metal. This process creates a strong bond between the two pieces of metal, making them one piece.

**Section 2: Types of Welding**

There are several types of welding, including:

1. Shielded Metal Arc Welding (SMAW) - also known as stick welding, this method uses a consumable electrode coated with a flux that produces a shielding gas.
2. Gas Metal Arc Welding (GMAW) - also known as MIG welding, this method uses a continuous wire electrode fed through a welding gun.
3. Flux Cored Arc Welding (FCAW) - similar to GMAW, but uses a continuous wire electrode contained within a cored wire.
4. Tungsten Inert Gas (TIG) Welding - also known as Gas Tungsten Arc Welding (GTAW), this method uses a non-consumable tungsten electrode and a separate shielding gas.
5. Plasma Arc Welding (PAW) - uses a plasma torch to heat the base metal and a consumable electrode.

**Section 3: How Does Welding Work?**

Welding works by creating an electric arc between the base metal and a filler metal. This electric arc generates enough heat to melt both metals, creating a pool of molten metal. As the base metal and filler metal mix, they form a strong bond.

**Section 4: Applications of Welding**

Welding has many applications, including:

1. Construction - building bridges, highways, and buildings.
2. Manufacturing - creating products such as cars, appliances, and tools.
3. Repair - fixing broken machines and structures.

### Section 3: Wire Wrapping
Wire wrapping is a popular technique used in jewelry making. It involves taking a piece of wire and bending it into a shape that will hold a gemstone or other object. This can be done using round, square, or triangular wire. To begin, you will need to cut a piece of wire about twice the length of your desired finished size. Then, use round nose pliers to create loops and twists in the wire until you have formed a secure cage around your gemstone.

### Section 4: Riveting
Riveting is another technique used in jewelry making. It involves using a rivet gun to join two pieces of metal together. To begin, you will need to choose a rivet that is the appropriate size for your project. Then, place the rivet in the hole of one of the pieces of metal and use the rivet gun to drive it through both pieces of metal and create a secure connection.

### Section 5: Casting
Casting is a technique used in jewelry making to create objects by pouring molten metal into a mold. To begin, you will need to create a wax model of your desired object. Then, use investment material to create a mold around the wax model. Finally, pour molten metal into the mold and allow it to cool and solidify. Once the metal has cooled, break apart the mold and reveal your cast object.

### Section 6: Stone Setting
Stone setting is a technique used in jewelry making to securely attach a gemstone to a piece of jewelry. There are several different types of stone settings, including prong settings, channel settings, and bezel settings. To begin, choose the appropriate stone setting for your gemstone and create a hole in your jewelry piece large enough to accommodate the gemstone.

Disgraced former MP Eric Joyce has insisted he’s not to blame for, well, everything that’s happened in British politics since he started a brawl in a House of Commons bar.

The butterfly effect theory runs that if Joyce had not kicked off in Stranger’s Bar one night in 2012, then the nation would look very different indeed.

The fracas, in which Joyce headbutted Tory Stuart Andrew and lamped his own party whip Phil Wilson, led to him giving up his Falkirk seat and quitting the Labour party.

That led to the infamous Falkirk selection fight which saw accusations that the contest was rigged by the unions and the Labour left.

As a result Ed Miliband drew up new rules for Labour membership, which included the option of paying just a few pounds to join and vote in leadership elections.

That allowed thousands to get involved in the 2015 leadership election and make Jeremy Corbyn leader. Corbyn’s ineffective campaigning and failure to deliver the Labour vote at the Brexit referendum is blamed by some for the Leave victory. And as a result of that Nicola Sturgeon is champing at the bit for another independence referendum and this week Theresa May called an early general election to essentially set up a five-year Brexit parliament.

“It’s quite a nice theory,” admits Joyce. “And on one level it’s factually true. But much as I like to self-aggrandise myself, if it hadn’t been Falkirk it would have been somewhere else.

“People were saying to me that the left were making a big push in Paisley to get rid of Douglas Alexander, then my thing came along and they made their stand in Falkirk rather than Paisley.

“Until that point I’d had running battles with the left, but I battered them down every year.”

After Joyce left Labour, Karie Murphy, now a key figure in Corbyn’s office and inner circle and close to Unite boss Len McCluskey, tried to win the nomination to replace him. But questions were raised about the role of Unite in the process and it was claimed that locals had been signed up to the party without their consent. As the scandal grew, then-Labour leader Miliband announced his fateful reforms to party membership in an effort to draw a line under it. (Labour later cleared Unite of any wrongdoing).

Joyce told me: “Ed was very weak with the left and he had this terrible gullibility. If it hadn’t had been Falkirk the same issues would have surfaced somewhere else.”

He has largely kept his head down since stepping down from Parliament two years ago, other than the occasional blog on the state of the Labour party or the issue of Scottish independence – which he now supports. He’s canned plans for an autobiography but claims he’s adapted some episodes from his life for a thriller instead.

However, in this rare intervention he’s scathing about Corbyn and also about the moderate Labour MPs who oppose him.

He said: “Jeremy Corbyn’s politics are quite literally bonkers.

“When I was an MP I took a lot of interest in Africa. I used to do quite a lot of stuff with Jeremy, he was really engaged and he just stayed behind the scenes focusing on his constituency and his issues. Then occasionally he’d make these bonkers speeches and I’d stay away.”

But he claims the current crop of MPs don’t have the skills to deal with the Corbynista tide.

The former soldier explained: “When I got selected I treated it like a campaign, I located in the constituency, contacted everyone, eventually I got selected, and when the left put their head above the parapet I knocked them down.

“A lot of current MPs got where they are by patronage, they’ve not had to fight battles, they’ve been special advisers. And when it came to Corbyn they weren’t able to carry their local party.

“Politics is all about numbers and organising. And while the Blairite bits of Labour write articles for Progress and tweet, the left just go and get the numbers.”

No longer a member, but describing himself as a Labour supporter, Joyce, an MP for 15 years from 2000, is gloomy about his former party’s prospects.

“It’s hard to see Labour in power before 2025, if ever," he said. "There was no coup, Labour had a nervous breakdown.”

Q:

Why multiply by $3^x/3^x$?

I was wondering is there a way to know what to multiply by? I just don't understand where $3^x/3^x$ came from. How did my teacher know that that's what we're supposed to multiply by? I understand how to do after that but that one part has stumped me. It was given as a hint.

A:

Actually your teacher explained it pretty well.
It is a trick that makes integral calculation easier. Your teacher is trying to match $e^{-3y}$ to $3^xy^x=(3y)^x$ in order to use the substitution method $u=3y$
Because $\frac{3^x}{3^x}=1$, multiplying this term to the whole integral will not change the result.
If you have something like $e^{-6y}$ instead in your integral, you will probably be doing $\frac{6^x}{6^x}$

A:

You can skip that step and instead just substitute $u=3y$ immediately into $$\frac{2^x}{x!}\int_0^\infty e^{-3y}y^xdy$$ to get $$\frac{2^x}{x!}\int_0^\infty e^{-u}(u/3)^x\frac{du}{3}=\frac{2^x}{x!}\int_0^\infty \frac{e^{-u}u^xdu}{3^x\cdot 3}=\frac{2^x}{x!3^{x+1}}\int_0^\infty e^{-u}u^xdu.$$
This of course gives the same result, but doesn't require you to magically come up with multiplying by $3^x/3^x$.  If you already knew this is how it was going to work out, you could see that you could factor out the $3^x$ before making the substitution.  This is what your teacher presumably did.

A:

As you mention, tricks are often clear in retrospect and not always easy to see immediately. Practice surely helps! The more problems you solve the easier it will be to see a few steps ahead.
In this case, notice that the integrand in last equation on the first line is $e^{-3y}y^x$. This equation sort of looks like the pdf of a gamma distribution. What the professor did is, essentially, add the missing pieces so that you end up with exactly a gamma distribution. Then, you can use the fact that a pdf always integrates to $1$ (if you integrate over all possible values) to get the solution you want. Of course, you can't just multiply by something in order to get the equation you want, you also have to divide by it (to keep your expression valid).

## Lesson: Understanding Substitution Method in Integration
### Introduction
The substitution method is a technique used in integration to simplify complex integrals by changing the variable. In this lesson, we will learn how to apply the substitution method in integration and understand why we multiply by $3^x/3^x$.
### Section 1: The Substitution Method
The substitution method involves finding a function that simplifies the integral. We start by finding a function that maps the original variable to a simpler one. We then take the derivative of this function with respect to the new variable and use it to evaluate the integral. Finally, we substitute the original variable back into the expression to get the simplified integral.
### Section 2: Example
Consider the integral $$\int_0^\infty e^{-3y}y^xdy$$
We want to find an expression for this integral that does not involve $y$ or $x$. Let's try substituting $u=3y$. Then, we have $$du=3dy$$ and $$y=u/3$$
Taking the derivative with respect to $u$, we get $$dy=-du/3$$
Substituting these expressions into the integral, we get $$-\frac{2^x}{x!}\int_0^\infty \frac{e^{-u}u^xdu}{3^x\cdot 3}=\frac{2^x}{x!}\int_0^\infty \frac{e^{-u}u^xdu}{3^x\cdot 3}$$
Simplifying the expression, we get $$\frac{2^x}{x!}\int_0^\infty \frac{e^{-u}u^xdu}{3^x\cdot 3}=\frac{2^x}{x!}\int_0^\infty \frac{e^{-u}u^xdu}{3^x\cdot 3}$$
This is the same integral as before, but with a factor of $3^x/3^x$ on the left side. This factor does not affect the value of the integral, so we can ignore it.
### Section 3: Why Multiply by $3^x/3^x$?
Now that we understand the substitution method and how it applies to integration, let's go back to our original question. Why do we multiply by $3^x/3^x$?
As we saw in the example, this factor does not affect the value of the integral. However, it is useful when we are trying to match two different expressions. By multiplying by $3^x/3^x$, we are essentially canceling out the $3^x$ terms in both expressions. This allows us to use the substitution method to match two expressions that would otherwise be difficult to compare.
### Conclusion
In this lesson, we learned about the substitution method in integration and why we multiply by $3^x/3^x$. We also saw an example of how this method can be applied to simplify a complex integral. By understanding this concept, we can apply it to other integrals and improve our problem-solving skills.
