Lesson: Introduction to Figure Drawing

**Objective:** To introduce students to the basics of figure drawing, including proportion, perspective, and shading techniques.

**Glossary:**
- **Proportion:** The relative size of different parts of the body
- **Perspective:** The way objects appear to change in size, shape, and position as they recede into the distance
- **Shading:** The use of light and dark to create the illusion of depth and texture on a surface

**Section 1: Proportion**

Proportion is an essential element of figure drawing. It refers to the relative size of different parts of the body. For example, the head is typically one-seventh the size of the torso. Understanding these proportions helps artists accurately represent the human form on paper.

**Questions:**
- What is proportion in figure drawing?
- How does the size of the head relate to the rest of the body?
- Can you think of any other examples of proportion in the human body?

**Answer:**
- Proportion refers to the relative size of different parts of the body in figure drawing. The head is typically one-seventh the size of the torso. Other examples of proportion in the human body include the length of the arms compared to the height, and the width of the shoulders compared to the hips.

**Section 2: Perspective**

Perspective is another crucial aspect of figure drawing. It refers to the way objects appear to change in size, shape, and position as they recede into the distance. Understanding perspective helps artists create accurate representations of the human form on paper.

**Questions:**
- What is perspective in figure drawing?
- How does perspective affect the appearance of objects in the distance?
- Can you think of any other examples of perspective in everyday life?

**Answer:**
- Perspective refers to the way objects appear to change in size, shape, and position as they recede into the distance. For example, objects closer to the viewer appear larger and more detailed than objects further away. Other examples of perspective in everyday life include the way buildings and roads appear to converge on the horizon, and the way shadows change length as the sun moves across the sky.

**Section 3: Shading**

Shading is the use of light and dark to create the illusion of depth and texture on a surface. It is an essential technique for creating realistic figures in figure drawing.

**Questions:**
- What is shading in figure drawing?
- How does shading create the illusion of depth and texture?
- Can you think of any other examples of shading in everyday life?

**Answer:**
- Shading refers to the use of light and dark to create the illusion of depth and texture on a surface. By varying the intensity of the lines, artists can create the illusion of three-dimensional forms on a two-dimensional surface. Other examples of shading in everyday life include the way shadows cast by objects create the illusion of depth and texture, and the way light and shadow play on surfaces such as walls and clothing.

**Conclusion:**

Understanding proportion, perspective, and shading are essential for creating accurate and realistic figure drawings. By practicing these techniques, students can improve their figure drawing skills and create compelling representations of the human form on paper.

**Glossary:**
- **Proportion:** The relative size of different parts of the body
- **Perspective:** The way objects appear to change in size, shape, and position as they recede into the distance
- **Shading:** The use of light and dark to create the illusion of depth and texture on a surface

Drinkable gardens

Local and homegrown foods have been a fad in Boulder for so long they’ve become passé — they’re the fodder of restaurant menus across the city. But the local food movement isn’t confined to your entrees. It’s a drinkable movement, too, that’s found its way into juices, teas and adult beverages around the county.

Paul Wright is new to Boulder — only a few months of residency. He stands just under 6 feet tall with reddish-blond hair and speaks with the slight drawl of a former Southerner. Wright moved to Boulder intending to open a restaurant that used only organic and locally sourced foods.

He did just that, opening Juiced Organic Market and Juicery in mid-May.

Wright was not initially the organic aficionado that he is today. His desire to cook with organic food developed while he was a restaurant owner in his home state of Louisiana.

He came to Boulder to make food for people who he thought would appreciate it.

“I would explain it to my partners and they would say, ‘You’re doing what? You’re doing an organic juice bar? Why?’ ‘Because there are people out there that do care about that,’” Wright says.

It isn’t possible to have an entirely local smoothie bar in Colorado due to the state’s inability to produce important tropical fruits like pineapples and bananas, Wright points out, but he does attempt to use every local item that he can, like locally made Noosa yogurt.

“I can’t wait till the summertime when I’ve got all of the local melons,” Wright says. “We will do an apple-melon smoothie that is all local.”

Although Wright currently does not grow his own food, he says he has mulled over the idea of starting a garden to supplement his restaurant or producing his own almond milk.

“That would be so cool, wouldn’t it?” Wright says. “That’s what it’s about anyway — getting your food from as close to the source as you possibly can. It’s what I believe in.”

Fruits and vegetables are important to Wright’s homemade drinks, but herbs and flowers can be used just as easily in beverages — and some ingredients can be found in your own backyard.

Rebecca Luna, owner and founder of Rebecca’s Herbal Apothecary and Supply, gets quite a few of her supplies from nearby Colorado locales. She has agreements with local farmers, allowing her to gather plants that she can use in her store. Many of them become ingredients in herbal teas.

Luna says that she uses “Mints, chamomile, calendula (a member of the daisy family) … passion flower, monarda, feverfew” and other herbs for her herbal tea blends.

“With the herbal teas, we support our local farmers,” she says. “It’s a seasonal thing — the amount that we get.”

Luna advised those who would like to grow their own ingredients for herbal teas to just look in their surrounding areas.

“I would look and see what grows really well here,” Luna says. “What is growing wild in the alleys? Your lemon balm and your mints. What’s growing naturally here and what’s abundant?”

Boulder Distillery, the home of 303 Vodka, mixes local ingredients into interesting cocktails. Brandi Schafer, CFO of Boulder Distillery, says that although the process for creating their spirits may not be unique, the way that they create their infusions and cocktails is special.

“The process is more my dad’s style and design, but when it comes to our cocktails and infusions, we really believe that fresh juices and fresh essences and herbs are a lot better than syrups and artificial flavorings,” Schafer says. “We believe in natural fruits to provide a much better flavor in everything that we do.”

Like Luna and Wright, most of the ingredients used are found locally. Almost all of the produce is gathered by going to farmers’ markets, she says.

“We get a lot of our cucumbers from farmers’ markets — strawberries as well,” Schafer says. “Most of our drinks are very seasonal, so when there are peaches or nectarines, we try to get them from the local farms and farmers’ markets, rather than a local grocery store chain.”

Schafer says that they don’t rely on one farmers’ market. The company travels to various farms and farmers’ markets in Boulder County to acquire produce for their drinks.

Dealing with similar seasonal issues as Wright, Schafer noted that many of the ingredients that they use changes depending on the season and availability of produce.

“Mainly the infusions are seasonal, for cost purposes, however we do try to get creative and invite customer suggestions for our infusions and drink ideas,” Schafer says. “Somebody suggested a blueberry mint the other day. … We try to make it a little bit more fun, complex and creative with our infusions.”

The infusion process at the distillery takes about a week, and the results are sampled to customers over a three-day period.

Schafer described her favorite cocktail served at the distillery — the “Shark Bite” — as a combination of a fruit-infused vodka that they have in stock, orange, pineapple and grapefruit juices, finished with cranberry, lime and lemon.

In the summer, whether they are smoothies, teas or cocktails, it is becoming just as easy to drink local as it is to eat local.

Lesson: The Importance of Local Food Movement

Introduction:

The local food movement has gained popularity in recent years, and it is not limited to just restaurants. It has also found its way into juices, teas, and adult beverages in Boulder, Colorado. This movement is essential because it promotes sustainability, supports local farmers, and reduces the carbon footprint. In this lesson, we will explore the importance of the local food movement and its impact on our community.

Section 1: What is the Local Food Movement?

The local food movement is a social and economic phenomenon that involves the production, processing, distribution, and consumption of food within a geographically defined region. The goal of this movement is to promote healthy, sustainable, and locally produced food.

Section 2: Why is the Local Food Movement Important?

The local food movement is essential for several reasons:

1. Sustainability: Locally produced food requires fewer resources to transport and store, reducing the carbon footprint and promoting sustainability.
2. Support for Local Farmers: The local food movement supports local farmers by providing them with a market for their products, which helps them stay in business and preserve their land.
3. Healthier Communities: Locally produced food is often fresher and more nutritious than imported food, leading to healthier communities.
4. Economic Development: The local food movement stimulates economic development by creating jobs and supporting local businesses.

Section 3: Practical Examples

1. Juiced Organic Market and Juicery: Paul Wright opened this restaurant in Boulder, Colorado, where he serves only organic and locally sourced foods. His restaurant is an excellent example of the local food movement in action.
2. Community-Supported Agriculture (CSA): CSA programs allow consumers to buy shares in a local farm, ensuring that the farmer receives a stable income and the community has access to fresh, locally grown produce.
3. Farmers' Markets: These markets provide an opportunity for local farmers to sell their products directly to consumers, supporting both the local economy and sustainable agriculture.

Section 4: Critical Thinking Questions

1. How does the local food movement benefit the environment?
2. What challenges does the local food movement face, and how can they be overcome?
3. How can we encourage more people to participate in the local food movement?

Glossary:

Local Food Movement: A social and economic phenomenon that involves the production, processing, distribution, and consumption of food within a geographically defined region.

Sustainability: The ability to exist, develop, and function without depleting natural resources or causing severe harm to the environment.

Conclusion:

The local food movement is essential for promoting sustainability, supporting local farmers, and improving the health of our communities. By choosing to purchase locally produced food, we can make a significant impact on our environment and support our local economy.

Labile ruthenium(ii) complexes with extended phenyl-substituted terpyridyl ligands: synthesis, aquation and anticancer evaluation.
Ruthenium complexes have been considered as promising substitutes for cisplatin in cancer chemotherapy. However, novel ruthenium-based therapies are faced with some limitations, such as unimpressive cytotoxicity toward solid tumors. Herein, we designed and synthesized phenyl-substituted terpyridyl ruthenium(ii) complexes ([Ru(tpy)(bpy)Cl](+) (Ru1), [Ru(phtpy)(bpy)Cl](+) (Ru2) and [Ru(biphtpy)(bpy)Cl](+) (Ru3)) which exhibited distinctly different anticancer activity. Ru1-Ru3 all underwent moderate aquation in buffer solution and this process was significantly inhibited by high chloride concentration. Cancer cells were found to readily uptake the relatively hydrophobic Ru3, as quantified using inductively coupled plasma mass spectrometry (ICP-MS). Ru1 was found to be non-cytotoxic (IC50 > 100 μM) while Ru3 exhibited very promising cytotoxicity on both two-dimensional (2D) cancer cell monolayers and 3D MCTSs. An antiproliferative assay revealed that Ru3 significantly inhibited cellular DNA replication which ultimately induced apoptosis of cancer cells.

textbook:
Lesson: Introduction to Ruthenium Complexes

### Overview:
In this lesson, we will learn about ruthenium complexes and their potential use in cancer treatment. We will cover the following topics:

1. What are ruthenium complexes?
2. Why are ruthenium complexes used in cancer treatment?
3. How are ruthenium complexes synthesized?
4. What are the properties of ruthenium complexes?
5. How do ruthenium complexes work in cancer treatment?
6. What are the challenges in using ruthenium complexes for cancer treatment?
7. How can we overcome these challenges?

### Section 1: What are ruthenium complexes?
Ruthenium complexes are compounds that contain a ruthenium atom bonded to other atoms or molecules. They have unique electronic and chemical properties that make them attractive for use in cancer treatment.

### Section 2: Why are ruthenium complexes used in cancer treatment?
Ruthenium complexes have been shown to be effective in killing cancer cells without harming healthy cells. They work by binding to DNA and causing damage to the cancer cell's ability to replicate. This damage eventually leads to the death of the cancer cell.

### Section 3: How are ruthenium complexes synthesized?
Ruthenium complexes can be synthesized by reacting ruthenium metal with various ligands. These ligands are molecules that can bind to the ruthenium atom and help to control its properties. The specific ligands used can greatly affect the properties of the resulting complex.

### Section 4: What are the properties of ruthenium complexes?
Ruthenium complexes have several properties that make them attractive for use in cancer treatment. They are often highly stable and resistant to breakdown. They also have a high affinity for binding to DNA, which is essential for their ability to kill cancer cells. Additionally, ruthenium complexes can be designed to have varying levels of solubility, which can affect their ability to be taken up by cancer cells.

### Section 5: How do ruthenium complexes work in cancer treatment?
Ruthenium complexes work in cancer treatment by binding to DNA and causing damage to the cancer cell's ability to replicate. This damage eventually leads to the death of the cancer cell. The specific mechanism by which ruthenium complexes cause this damage is still being studied, but it is believed to involve the production of reactive oxygen species and the disruption of DNA repair pathways.

### Section 6: What are the challenges in using ruthenium complexes for cancer treatment?
One major challenge in using ruthenium complexes for cancer treatment is their lack of selectivity for cancer cells over healthy cells. This means that they may also harm healthy cells, leading to side effects and toxicity. Additionally, many ruthenium complexes are sensitive to changes in pH or redox conditions, which can limit their effectiveness in the body.

### Section 7: How can we overcome these challenges?
To overcome these challenges, researchers are working to develop new ruthenium complexes with improved selectivity for cancer cells and increased stability under physiological conditions. Additionally, ongoing research is exploring ways to improve the delivery of ruthenium complexes to cancer cells, such as through the use of nanoparticles or other drug delivery systems. By addressing these challenges, it may be possible to develop more effective and safer ruthenium-based cancer therapies.

Mentoring Objectives & Scope

What Students Can Expect From Me: First of all, I consider it an honor to be participating in this program. I have also been fortunate to have an interesting and enjoyable career. Hopefully my background and career experience can be of some help to the students that I work with.

Over the years I have found that each and every student that I have been fortunate to work with has had different needs, wants and expectations for the program. As such, my approach to mentoring is fairly unstructured. I like to listen and get to know the student then move our sessions into the direction that will be most beneficial to the student. I have found that after an initial group meeting with the student, we generally move into more personal one on one meeting that we conduct over coffee or lunch whatever is most convenient for the student.

Preffered Discussion Topics & Activities:I pretty much leave this up to the student and try to accommodate their specific interests.

Objectives:The greatest satisfaction that I get out this program is having the student feel like the program was helpful and in some small way made a difference in their life.

When and where do you hold meetings with your students?

I'm very flexible on this. Meeting at Seattle University would be fine as well.

Lesson: Employment History

Introduction: Employment history refers to the chronological list of the jobs an individual has held, including positions held, duration of employment, and achievements in each role. It is an essential part of a person's resume or CV and provides insight into their professional journey.

Section 1: Understanding Employment History

**Theoretical Concept:** Employment history is a record of an individual's work experience, which includes job titles, employers, dates of employment, and accomplishments.

**Practical Example:** Suppose John Smith has worked as a software engineer for five years at Microsoft Corporation. His employment history would include his job title, the name of his employer, the dates he worked there (from 2015 to 2020), and his achievements during his tenure, such as developing a successful mobile application.

**Real-World Scenario:** A job seeker applies for a position as a marketing manager at a company. The hiring manager reviews their resume and finds their employment history impressive because they have consistently risen through the ranks in marketing, demonstrating their expertise in the field.

Section 2: Creating an Effective Employment History

**Theoretical Concept:** An effective employment history is one that highlights your achievements, showcases your skills and experiences, and is organized chronologically.

**Practical Example:** If you have worked in different industries or roles, you should organize your employment history chronologically, starting with your most recent job. For each position, include your job title, the name of your employer, the dates you worked there, and your achievements.

**Real-World Scenario:** A job seeker creates an effective employment history by listing their previous positions, dates of employment, job titles, and accomplishments. They also ensure that their employment history reflects their skills and experiences, making them stand out from other applicants.

Section 3: Evaluating Employment History

**Theoretical Concept:** Evaluating employment history involves analyzing a person's work experience to understand their skills, achievements, and potential.

**Practical Example:** A recruiter evaluates a job seeker's employment history to determine if they have the necessary skills and experience for the position they are applying for. They look for relevant job titles, employers, and achievements that demonstrate the individual's expertise in the field.

**Real-World Scenario:** A hiring manager evaluates a candidate's employment history and finds that they have consistently risen through the ranks in marketing, indicating their dedication and expertise in the field.

Conclusion: Understanding employment history is essential when applying for jobs, as it provides insight into a person's professional journey. By creating an effective employment history and evaluating others' employment history, you can make informed decisions about your career path.

Glossary:
- Employment history: A record of an individual's work experience, including job titles, employers, dates of employment, and accomplishments.

Effect of some plant growth regulators on lindane and alpha-endosulfan toxicity to Brassica chinensis.
The effect of indolebutyric acid (IBA) and gibberellic acid (GA3), to alleviate the organochlorine phytotoxicity were studied in Brassica chinensis. Presence of organochlorine decreased Brassica chinensis seedlings growth in contaminated alkaline soil. One mg l(-1) IBA could enhance 14 and 26% shoot and root length of B. chinensis seedlings grown at 40 mg kg(-1) lindane contaminated soil, respectively. Ten mg l(-1) IBA also increased 80 and 40% root fresh weight of seedling grown in 40 mg kg(-1) lindane and alpha-endosulfan contaminated soils, respectively. However, IBAhad no effect on shoot and root length of seedlings grown in endosulfan contaminated soil. On the other hand, 10 mg l(-1) GA3 only increased 80% of shoot and root fresh weigh of B. chinensisin 40 mg kg(-1) endosulfan contaminated soil. External auxin addition could increase B. chinensis growth in lindane more than endosulfan contaminated soil. External gibberellin was less effective than external auxin to increase B. chinensis growth in organochlorine contaminated soil. There is possibility that auxin could decrease organochlorine phytotoxicity in plants and hence can be useful for organochlorine phytoremediation.

textbook:
Lesson: Effect of Plant Growth Regulators on Organochlorine Phytotoxicity

Introduction:
Plant growth regulators (PGRs) are chemicals that help plants grow and develop properly. They can be used to control plant growth, improve crop yields, and protect plants from pests and diseases. In this lesson, we will learn about the effects of two PGRs, indolebutyric acid (IBA) and gibberellic acid (GA3), on the growth of Brassica chinensis seedlings in contaminated soil.

Objectives:
1. Understand the effects of IBA and GA3 on Brassica chinensis seedlings grown in contaminated soil.
2. Learn about the role of PGRs in improving plant growth and development.
3. Apply the knowledge gained to understand the effects of PGRs on other plants and crops.

Section 1: Introduction to Plant Growth Regulators

Plant growth regulators (PGRs) are chemicals that help regulate plant growth and development. They are classified into three main groups: auxins, cytokinins, and gibberellins. Auxins are responsible for cell elongation, while cytokinins promote cell division. Gibberellins help seeds germinate and promote stem elongation.

Section 2: Effect of IBA and GA3 on Brassica chinensis Seedlings

A study was conducted to determine the effects of IBA and GA3 on Brassica chinensis seedlings grown in contaminated soil. The results showed that:

- One mg l(-1) IBA could enhance 14 and 26% shoot and root length of B. chinensis seedlings grown at 40 mg kg(-1) lindane contaminated soil, respectively.
- Ten mg l(-1) IBA also increased 80 and 40% root fresh weight of seedling grown in 40 mg kg(-1) lindane and alpha-endosulfan contaminated soils, respectively.
- However, IBA had no effect on shoot and root length of seedlings grown in endosulfan contaminated soil.
- On the other hand, 10 mg l(-1) GA3 only increased 80% of shoot and root fresh weigh of B. chinensis in 40 mg kg(-1) endosulfan contaminated soil.
- External auxin addition could increase B. chinensis growth in lindane more than endosulfan contaminated soil.
- External gibberellin was less effective than external auxin to increase B. chinensis growth in organochlorine contaminated soil.

Section 3: Role of Plant Growth Regulators in Plant Growth and Development

PGRs play a crucial role in plant growth and development by regulating various physiological processes such as cell division, elongation, and differentiation. They help plants adapt to environmental changes, respond to stress, and improve crop yields.

Section 4: Applying Knowledge to Other Plants and Crops

The effects of PGRs on plant growth can be applied to other plants and crops. For example, farmers can use PGRs to improve crop yields, protect plants from pests and diseases, and control plant growth.

Conclusion:

In conclusion, the study showed that IBA and GA3 can help improve the growth of Brassica chinensis seedlings in contaminated soil. This knowledge can be applied to other plants and crops to improve their growth and development. Understanding the effects of PGRs on plant growth and development is essential for agriculture and horticulture.

When you decide to switch, and have got the ball rolling with your new supplier, you should settle any outstanding debts. If you have bills that are more than 28 days old, you might find that you can’t change supplier until you’ve paid them. But there are some exceptions to the 28 days – for example, if you are less than £200 in debt, then your switch could still go ahead as normal
Utility companies are responsible for transmission and delivery of electricity even in energy deregulated parts of Texas and should be contacted in the event of a power outage. Your retail energy supplier may provide you competitive electric rates or exceptional customer service, but they cannot repair power lines or restore your service. In the case of an emergency, contact:
Keeping track of the trends and price fluctuations in the energy market is key if you want to find cheap electricity in Stafford. SaveOnEnergy.com® can help you monitor Stafford electricity rates so you can buy when the time is right. We partner with a number of electricity companies in Stafford to bring you up-to-date information on rates and plan options. Using our tools, you can compare electricity rates until you find a plan that works for your needs. Just enter your ZIP code now to get started.
The freedom to choose your energy rates in Maryland is not only available in homes but also to commercial customers. In fact, more than 90% of large businesses in the state have enrolled with alternative suppliers. This competition between energy suppliers to provide lower prices for businesses could be why commercial electric prices in Maryland are lower than the national average this year. If the same competition between suppliers existed for residential customers, prices might also decrease. However, without participation in energy choice, suppliers are not forced to compete for your business. Want to see the available rates? Enter your ZIP code above.
In finding you the best Texas electric rates, we only list electric companies that have great business stability, excellent service, environmental awareness, and transparent pricing. This protects you from providers that could soon go out of business, are unattentive to customers, are environmentally unsound, or may end up charging you a higher rate than advertised.
Price, of course. Prices are expressed in cents/kilowatt hour. Plan types include fixed rates and variable rates. Fixed rates offer consistency throughout the plan term, which can run from six to 36 months. Variable rates can change monthly - they're great when prices go down, but not-so-great when they don't. Finally, if you care about your carbon footprint, you may choose a plan sourced by solar or wind energy.

Texas deregulated most of the state's electricity markets in 2002, a move aimed at lowering electricity costs by letting consumers choose their own electric power providers and their own plans. Some parts of Texas continued to be regulated, including those whose power is proved by municipally-owned utilities, electric cooperatives and investor-owned utilities that operate outside the state's primary power grid.

Then, in 2002, Texas deregulated the electricity market and everybody cheered! Except that, sure, deregulation opened up the market to competition that may (or may not) have resulted in lower rates, but it introduced a whole host of other issues.

Lesson: Understanding Energy Deregulation and Switching Suppliers

Introduction:
In this lesson, we will learn about energy deregulation and switching suppliers. We will cover the basics of how energy markets work, what utility companies do, and how to switch suppliers to get the best deal on your electricity bill. By the end of this lesson, you will be able to understand the energy market, make informed decisions about your energy consumption, and save money on your electricity bills.

Section 1: Understanding Energy Deregulation

Topic 1: What is Energy Deregulation?
Energy deregulation refers to the process of separating the generation and distribution of electricity from the utilities that sell it to consumers. This means that different companies can compete to generate electricity, and consumers can choose which company they want to buy their electricity from.

Topic 2: How does Energy Deregulation Work?
In an energy deregulated market, there are two types of companies involved in the production and distribution of electricity: Generation Companies (GENCOs) and Distribution Companies (DISCOs). GENCOs generate electricity, while DISCOs distribute it to consumers. Consumers can choose which GENCO to buy their electricity from, and this choice determines the rate they pay for their electricity.

Topic 3: Why was Energy Deregulation Introduced?
Energy deregulation was introduced to promote competition in the electricity market, which would lead to lower prices and better service for consumers. Before deregulation, utilities had a monopoly over the generation, transmission, and distribution of electricity, which meant that they had little incentive to innovate or improve their services.

Section 2: Switching Suppliers

Topic 1: How to Switch Suppliers
To switch suppliers, you need to follow these steps:
1. Research different suppliers and compare their rates to find the best deal.
2. Contact your current supplier to let them know you want to switch.
3. Contact your new supplier to set up your account.
4. Wait for your new supplier to transfer your service.

Topic 2: What to Look for When Switching Suppliers
When switching suppliers, look for the following:
1. Rates: Make sure the rate you are being offered is competitive and lower than your current rate.
2. Contract Length: Some suppliers require you to sign a contract for a certain period of time, so make sure you are comfortable with the length of the contract.
3. Customer Service: Read reviews and ratings from other customers to see how well the supplier handles customer service issues.
4. Fees: Some suppliers charge fees for early termination or late payments, so make sure you understand all the fees before signing up.

Section 3: Conclusion

In conclusion, energy deregulation has opened up the electricity market, allowing consumers to choose which company they want to buy their electricity from. By researching different suppliers and understanding the terms of their contracts, you can switch suppliers to get the best deal on your electricity bill. Remember to consider factors such as rates, contract length, customer service, and fees when making your decision.

Q:

Prove $\sum_{k=1}^n \frac{1}{(2k-1)(2k+1)}=\frac{n}{2n+1}$

I have attached an image of a kind of mathematical induction question that i have never seen before. I attached it because i don't know how to type all the symbols out properly, i'm sorry again would really appreciate any help :)

Prove that $$\sum_{k=1}^n \frac{1}{(2k-1)(2k+1)}=\frac{n}{2n+1}$$
Use this to evaluate $$\sum_{k=13}^{37} \frac{1}{4k^2-1}$$

A:

Let me address your problem one-by one:

The "sigma" denoted by $\sum$ actually means summation, if you already did not know it. Using this sign or operator as you wish to call it, we can rewrite $a_1+a_2+a_3+\ldots +a_n$ as$\sum_{k=1}^n a_k$.
The induction comes up easily:

In this case, the mathematical statement $$P(n) : \sum_{k=1}^n \frac{1}{(2k-1)(2k+1)}=\frac{n}{2n+1}$$
First of all, as given, we have that L.H.S.$=\sum_{k=1}^1 \frac{1}{(2k-1)(2k+1)}=\frac{1}{(2-1)(2+1)}=\frac{1}{2+1}=$R.H.S.
So $P(1)$ is true.
Now, using induction, assume that $P(m)$ is true i.e. $$\sum_{k=1}^m \frac{1}{(2k-1)(2k+1)}=\frac{m}{2m+1}$$

Thus, we can say that $$\begin{align} & \sum_{k=1}^{m+1}
  \frac{1}{(2k-1)(2k+1)} \\ & =\sum_{k=1}^m \frac{1}{(2k-1)(2k+1)} +
 \frac{1}{[2(m+1)-1][2(m+1)+1]} \\ & =\frac{m}{2m+1} +
 \frac{1}{(2m+1)(2m+3)} \\ & =\frac{m(2m+3)+1}{(2m+1)(2m+3)} \\ &
 =\frac{2m^2+3m+1}{(2m+1)(2m+3)} \\ & =\frac{(2m+1)(m+1)}{(2m+1)(2m+3)} \\ &     =\frac{(m+1)}{2(m+1)+1}\end{align}$$

So $P(m+1)$ is true.
Hence, the truth of $P(m) \Rightarrow P(m+1)$ is true and the statement given is proved to be true by principle of mathematical induction.

The second part of your answer comes up from the above result:

$$\begin{align} & \sum_{k=13}^{37} \frac{1}{4k^2-1} \\ &
 =\sum_{k=1}^{37} \frac{1}{4k^2-1}-\sum_{k=1}^{12} \frac{1}{4k^2-1} \\ & =\sum_{k=1}^{37} \frac{1}{(2k-1)(2k+1)}-\sum_{k=1}^{12}
 \frac{1}{(2k-1)(2k+1)} \\ &
 =\frac{37}{74+1}-\frac{12}{24+1}\end{align}$$

I hope you now understand.

A:

Hints: As your know first you need check the first identity for $n=1$. After presume that for $n$ the identity holds. Then you need to show $n\implies n+1$, write the details that why we need to show
$$\frac{n}{2n+1}+\frac{1}{(2(n+1)-1)(2(n+1)+1)}=\frac{(n+1)}{2(n+1)+1}.$$
You need to divide polynomials or relate $(n+1)(2n+1)=2n^2+3n+1$ with previous computation. The second question is an specialization of the first identity, since we know the remarkable identity involving the quotients. Welcome to this site, also try next time show your effort and write in TEX, is easy with this Tutorial

A:

This is a solution without induction, if you're interested in another method working in such cases (to do induction, you have to know the result, while telescoping sum works without it).
Observe that
$$
\frac{1}{(2k-1)(2k+1)}=\frac{1}{2}\left(\frac{1}{2k-1}-\frac{1}{2k+1}\right)
$$
Hence your sum telescopes:
$$
\sum_{k=1}^{n}\frac{1}{(2k-1)(2k+1)}=\frac{1}{2}\left(\frac{1}{2\cdot 1-1}-\frac{1}{2\cdot n+1}\right)=\frac{n}{2n+1}
$$
(only first and last term are not cancelled)

Lesson: Proving a Mathematical Induction Statement

Introduction:
In this lesson, we will learn how to prove a mathematical induction statement using the given formula. We will start with an overview of what mathematical induction is and then move on to the steps involved in proving such a statement. Finally, we will apply this knowledge to solve a related problem.

What is Mathematical Induction?
Mathematical induction is a method used to prove statements or theorems in mathematics. It involves proving a statement for a base case (usually n=1) and then assuming the statement is true for some arbitrary n and using this assumption to prove it is true for n+1.

Steps in Proving a Mathematical Induction Statement
1. State the statement to be proven (in this case, the formula).
2. Prove the statement for the base case (n=1).
3. Assume the statement is true for some arbitrary n.
4. Use this assumption to prove that the statement is true for n+1.

Proof of the Formula
Using the formula given in the question, we want to prove that $$\sum_{k=1}^n \frac{1}{(2k-1)(2k+1)}=\frac{n}{2n+1}$$

Step 1: State the statement to be proven
$$\sum_{k=1}^n \frac{1}{(2k-1)(2k+1)}=\frac{n}{2n+1}$$

Step 2: Prove the statement for the base case (n=1)
When n=1, the left side of the equation becomes:
$$\sum_{k=1}^1 \frac{1}{(2k-1)(2k+1)}=\frac{1}{(2-1)(2+1)}=\frac{1}{2+1}=1$$
And the right side becomes:
$$\frac{1}{2\cdot1+1}=\frac{1}{3}$$
Both sides are equal, so the statement holds for n=1.

Step 3: Assume the statement is true for some arbitrary n
We assume that the statement is true for some arbitrary n, i.e.,
$$\sum_{k=1}^n \frac{1}{(2k-1)(2k+1)}=\frac{n}{2n+1}$$

Step 4: Use this assumption to prove that the statement is true for n+1
Now, we want to prove that the statement is true for n+1, i.e.,
$$\sum_{k=1}^{n+1} \frac{1}{(2k-1)(2k+1)}=\frac{(n+1)}{2(n+1)+1}$$

Notice that when n=1, we have:
$$\sum_{k=1}^{1} \frac{1}{(2k-1)(2k+1)}=\frac{1}{(2-1)(2+1)}=\frac{1}{2+1}=1$$
And:
$$\frac{(1)+1}{2(1)+1}=\frac{2}{5}$$

Similarly, when n=2, we have:
$$\sum_{k=1}^{2} \frac{1}{(2k-1)(2k+1)}=\frac{2}{3}$$
And:
$$\frac{(2)+1}{2(2)+1}=\frac{3}{7}$$

In general, we can see that:
$$\sum_{k=1}^n \frac{1}{(2k-1)(2k+1)}=\frac{n}{2n+1}$$
$$\sum_{k=1}^{n+1} \frac{1}{(2k-1)(2k+1)}=\frac{(n+1)}{2(n+1)+1}$$

Comparing the two expressions, we can see that they are equivalent, and thus the statement is true for n+1.

Conclusion:
We have successfully proved the given formula using mathematical induction. Now, let's use this knowledge to solve a related problem.

Problem: Evaluate $$\sum_{k=13}^{37} \frac{1}{4k^2-1}$$

Solution:
Since we have proved the given formula, we can use it to evaluate the problem. First, we need to find a way to relate the given expression to the one in the problem. Notice that:
$$\frac{1}{(2k-1)(2k+1)}=\frac{1}{(2(k-1)+1)(2k+1)}$$
And:
$$\frac{1}{4k^2-1}=\frac{1}{(2k-1)^2}$$

Multiplying both sides of the second equation by 4, we get:
$$\frac{1}{4k^2-1}=\frac{1}{(2k-1)^2}=\frac{1}{(2(k-1)+1)^2}$$

Now, we can rewrite the given expression as:
$$\sum_{k=1}^n \frac{1}{(2k-1)^2}=\frac{n}{2n+1}$$

Substituting n=37 in the above equation, we get:
$$\sum_{k=1}^{37} \frac{1}{(2k-1)^2}=\frac{37}{2(37)+1}$$

Simplifying, we get:
$$\sum_{k=1}^{37} \frac{1}{(2k-1)^2}=\frac{37}{74}$$

Thus, the value of the given expression is $\frac{37}{74}$.

Lesson: The Importance of Regular Maintenance for Air Conditioning Systems

**Introduction**

Air conditioning systems are essential for maintaining a comfortable indoor environment, especially during hot summer months. Regular maintenance of these systems is crucial to ensure their optimal functioning and longevity. In this lesson, we will learn about the importance of regular maintenance for air conditioning systems and how it can save you money and prevent costly repairs.

**Section 1: Theoretical Concepts**

What is an air conditioning system?
An air conditioning system is a machine that cools and dehumidifies indoor air by removing heat and moisture. It consists of two main components: the condenser and the evaporator.

Why is regular maintenance important for air conditioning systems?
Regular maintenance of air conditioning systems is important because it helps to prevent breakdowns, prolong the life of the system, and reduce energy consumption. It also ensures that the system is operating at peak efficiency, which can save you money on your energy bills.

**Section 2: Practical Examples**

Let's consider a real-world scenario where regular maintenance could have prevented a costly repair. Suppose you have a central air conditioning system installed in your home. Over time, the air filter becomes clogged with dust and dirt, reducing the airflow and causing the system to work harder than necessary. As a result, your energy bills increase, and the system's lifespan shortens. If you had performed regular maintenance on your system, such as changing the air filter every three months, you could have avoided this problem and saved money on your energy bills.

**Section 3: Self-Debating Discussions**

Topic: How often should I perform maintenance on my air conditioning system?
Argument 1: Regular maintenance should be performed once a year before the start of the cooling season. This will ensure that the system is ready for use and will operate efficiently throughout the summer months.
Argument 2: Depending on the usage and conditions of the system, it may be necessary to perform maintenance more frequently, such as twice a year or even quarterly.

**Glossary**

- Condenser: A component of an air conditioning system that is located outside the building and removes heat from the refrigerant.
- Evaporator: A component of an air conditioning system that is located inside the building and absorbs heat from the indoor air.
- Blower: A fan that circulates air over the evaporator coil and into the room.

**Conclusion**

Regular maintenance of air conditioning systems is essential for ensuring their optimal functioning and longevity. By performing routine tasks such as changing air filters and cleaning condenser units, you can prevent costly repairs and save money on your energy bills. Remember to consult with a professional HVAC technician to determine the appropriate maintenance schedule for your specific system.

Lesson: Introduction to Email Filters and PLSA

## Section 1: Introduction
In this lesson, we will learn about email filters and PLSA (Per-List Subscription Addresses). We will cover the following topics:

- What are email filters and PLSA?
- Why use PLSA instead of email filters?
- How do you set up PLSA?

## Section 2: What are email filters and PLSA?
Email filters are rules that sort incoming emails into specific folders based on certain criteria. For example, you can filter emails from a specific sender to go directly to your trash folder. PLSA (Per-List Subscription Addresses) are email addresses that are used to subscribe to mailing lists.

## Section 3: Why use PLSA instead of email filters?
Using PLSA instead of email filters has several advantages:

- It is more reliable because it eliminates the need for complex filtering rules.
- It is less fragile because it does not depend on email providers' filtering systems.
- It is cheaper because it requires fewer resources to manage.

Q:

Calculate the number of records for each day

I have user sign up. I want to display a graph for the last 7 days with the number of sign ups on each day based on the created_at record
Can i use active record query to achieve this with some kind of grouping and count instead of calculating it manually through iteration?

A:

Use to_date which will get rid of all time information, effectively leaving you with just the days.
User.where('created_at >= ?', 1.week.ago).group_by { |u| u.created_at.to_date }.map { |_,v| [_, v.length]}.to_h
OR, if you don't care about the time portion, you could use this:
User.where('created_at >= ?', 1.week.ago).group(:created_at).count
This will get you a  hash with the created_at and count.

Lesson: How to Count Records for Each Day Using Active Record Query

**Introduction**

In this lesson, we will learn how to use Active Record queries to count records for each day. We will use the "created_at" column to group records by day and count the number of records for each day. This technique can be applied to other scenarios where you need to group records by day or any other time period.

**Section 1: Theory**

Active Record is a powerful tool for querying databases in Ruby on Rails applications. One common task is to count records for each day within a given time period. To achieve this, we can use the "group" method to group records by day and the "count" method to count the number of records for each day.

**Section 2: Practice**

Let's say we have a User model with a "created_at" column that stores the date and time when the user signed up. We want to display a graph for the last 7 days with the number of signups on each day.

Here's an example Active Record query that achieves this:

```ruby
User.where('created_at >= ?', 1.week.ago).group_by { |u| u.created_at.to_date }.map { |_, v| [_, v.length]}.to_h
```

This query groups records by day using the "created_at.to_date" method, which gets rid of the time information, effectively leaving us with just the days. It then maps the grouped records to a hash where the keys are the dates and the values are the number of records for each day.

Alternatively, if we don't care about the time portion of the "created_at" column, we can use the following query:

```ruby
User.where('created_at >= ?', 1.week.ago).group(:created_at).count
```

This query groups records by the "created_at" column and counts the number of records for each group.

**Section 3: Practical Examples**

Let's say we have the following data in our database:

| id | name | created_at           |
|----|------|----------------------|
| 1  | John | 2021-09-01 10:00:00 |
| 2  | Jane | 2021-09-01 11:00:00 |
| 3  | Bob  | 2021-09-02 10:00:00 |
| 4  | Alice| 2021-09-02 11:00:00 |
| 5  | Eve  | 2021-09-03 10:00:00 |
| 6  | Adam | 2021-09-03 11:00:00 |

Using the first query above, we would get the following hash:

```ruby
{
  "2021-09-01" => 2,
  "2021-09-02" => 2,
  "2021-09-03" => 2
}
```

Using the second query above, we would get the following hash:

```ruby
{
  "2021-09-01 10:00:00" => 1,
  "2021-09-01 11:00:00" => 1,
  "2021-09-02 10:00:00" => 1,
  "2021-09-02 11:00:00" => 1,
  "2021-09-03 10:00:00" => 1,
  "2021-09-03 11:00:00" => 1
}
```

**Glossary**

- Active Record: A powerful tool for querying databases in Ruby on Rails applications.
- Group: Groups records by a specified attribute.
- Count: Counts the number of records for each group.
- To_date: Converts a datetime or timestamp to a date without time zone information.
- Hash: A data structure that stores key-value pairs.

**Conclusion**

In this lesson, we learned how to use Active Record queries to count records for each day. We covered the theory behind the technique, practiced with examples, and defined key terms. This skill can be applied to other scenarios where you need to group records by day or any other time period.

Characteristics of children under 2 years of age undergoing tonsillectomy for upper airway obstruction.
To study characteristics of children less than 2 years who underwent a tonsillectomy for sleep disordered breathing (SDB) or obstructive sleep apnea (OSA) to assess for factors associated with requesting a preoperative polysomnogram (PSG) and to identify predictors of upper airway obstruction in this group. A retrospective chart review of children under 2 years who underwent a tonsillectomy over a 7-year period at a tertiary care pediatric hospital was undertaken. Patient demographics, characteristics and polysomnography results, when applicable, were collected. In order to determine if the gathered demographics of our cohort differed from the non-surgical population, we compared our data with available Colorado data for each variable. Children were stratified by OSA severity using their obstructive apnea-hypopnea index (OAHI). 197 (2.2%) of 9038 patients who underwent tonsillectomy for SDB or OSA were ≤ 24 months. The proportions of male, African-American, Hispanic, obese, underweight, premature, syndromic and daycare patients in our cohort were significantly different than in the general population. In a multivariate model, the odds of African-Americans having severe OSA were 12.5 times greater than the odds of Caucasians. The odds of patients with syndromes or craniofacial anomalies were 11 times greater (p < 0.0001), and the odds of patients in daycare were 2.2 times lower (p = 0.04) of undergoing a PSG before tonsillectomy. Weight did not influence polysomnogram requests. In children under 2 years, ethnicity seems to be a predictor of OSA severity. African-American, prematurity, daycare and Down syndrome patients were significantly more represented in our study population. PSG is more likely to be requested for syndromic children.

Light can also damage collection materials, particularly those that are sensitive to light, such as photographs, prints, and manuscripts. Prolonged exposure to light can cause fading, discoloration, and other forms of damage.

Question: How can you protect collection materials from light damage?
Answer: You can protect collection materials from light damage by storing them in dark enclosures, such as boxes or folders made of acid-free materials, and by using window shades or curtains to block out natural light.

Section 2: Types of Monitoring Devices

Topic 1: Data Loggers
Data loggers are electronic devices that record environmental conditions over time. They can be used to monitor temperature, humidity, and light levels, among other factors.

Question: What are some common types of data loggers used in libraries and archives?
Answer: Some common types of data loggers used in libraries and archives include thermometers, hygrometers, and light meters.

Topic 2: Thermochromic Ink
Thermochromic ink is a type of ink that changes color in response to temperature changes. It can be used to monitor temperature fluctuations in collection materials.

Question: How does thermochromic ink work?
Answer: Thermochromic ink works by changing color in response to temperature changes. When the temperature rises above a certain point, the ink changes from one color to another, indicating that the temperature is too high.

Section 3: Interpreting Monitoring Data

Topic 1: Trend Analysis
Trend analysis involves analyzing the data collected by monitoring devices over time to identify patterns and trends. This can help you identify potential problems before they become serious.

Question: How often should you check your monitoring devices?
Answer: You should check your monitoring devices at least once a month to ensure that environmental conditions are within the recommended ranges.
