Lesson: How to Fabricate Composite Parts

Introduction:
Composite parts are made up of two or more materials, such as fiberglass and resin, which are combined to create a stronger and more durable material. These parts are commonly used in the aerospace, automotive, and construction industries. In this lesson, we will learn about the process of fabricating composite parts, including the steps involved and the tools required.

Section 1: Overview of Composite Fabrication

Topic 1.1: What is Composite Fabrication?
Composite fabrication is the process of creating composite parts by combining different materials, such as fiberglass, carbon fiber, and resin. These parts are lightweight, strong, and resistant to damage.

Topic 1.2: Why is Composite Fabrication Important?
Composite fabrication is important because it allows us to create parts that are stronger and lighter than traditional materials. This makes them ideal for use in aerospace, automotive, and construction applications where strength and weight are critical factors.

Section 2: Steps Involved in Composite Fabrication

Topic 2.1: Preparation of Materials
The first step in composite fabrication is preparing the materials. This involves cutting and shaping the fibers and resin to the desired shape and size.

Topic 2.2: Layup
The next step is laying up the fibers and resin onto a mold. This is done using a process called layup, where the fibers are woven together in a specific pattern to create the desired strength and flexibility.

Lesson Title: Introduction to Machine Learning Algorithms

### Overview
In this lesson, we will learn about the basics of machine learning algorithms, including their applications and how they work. We will focus on one specific algorithm, Kohonen's algorithm, and understand its role in pattern recognition.

### Objectives
By the end of this lesson, you will be able to:

1. Define machine learning algorithms and their applications.
2. Explain the role of Kohonen's algorithm in pattern recognition.
3. Understand the steps involved in Kohonen's algorithm.
4. Apply critical thinking skills to analyze and evaluate the effectiveness of machine learning algorithms.

### Section 1: Introduction to Machine Learning Algorithms

Machine learning algorithms are computer programs that can learn from data and make predictions or decisions without being explicitly programmed. They are used in a variety of applications, such as image recognition, speech recognition, and natural language processing.

One of the most popular machine learning algorithms is Kohonen's algorithm, which is used for pattern recognition. It works by fitting a k-dimensional grid of points to a set of points taken from a k-manifold in Rn, for k⩽n. This algorithm is inspired by a neural model and bears some of the marks of its ancestry.

### Section 2: Kohonen's Algorithm for Pattern Recognition

Kohonen's algorithm is a type of unsupervised learning algorithm that is used for clustering and classification tasks. It works by iteratively adjusting the weights of the neurons in a neural network to minimize the distance between the input data points and the output data points.

The steps involved in Kohonen's algorithm are as follows:

1. Initialize the weights of the neurons randomly.
2. Present an input data point to the neural network.
3. Calculate the error between the input data point and the output data point.
4. Adjust the weights of the neurons based on the error.
5. Repeat steps 2-4 until the error reaches a desired level.

Kohonen's algorithm is particularly useful for pattern recognition tasks because it can learn to recognize patterns even when they are partially hidden or distorted.

### Section 3: Applications of Machine Learning Algorithms

Machine learning algorithms have a wide range of applications in fields such as finance, healthcare, marketing, and transportation. Some of the most common applications include:

1. Image recognition: Machine learning algorithms can be trained to recognize objects in images or videos. For example, self-driving cars use machine learning algorithms to recognize traffic lights, pedestrians, and other vehicles.

2. Speech recognition: Machine learning algorithms can be used to transcribe spoken words into text. This technology is used in virtual assistants like Siri and Alexa.

3. Natural language processing: Machine learning algorithms can be used to analyze and understand human language. This technology is used in chatbots and language translation software.

4. Fraud detection: Machine learning algorithms can be used to detect fraudulent activities in financial transactions.

5. Medical diagnosis: Machine learning algorithms can be used to analyze medical data and help doctors make more accurate diagnoses.

### Section 4: Critical Thinking

As with any type of algorithm, machine learning algorithms have their limitations and assumptions. It is essential to critically evaluate the effectiveness of these algorithms and consider factors such as:

1. The quality and quantity of the data used to train the algorithm.
2. The representativeness of the data used to train the algorithm.
3. The generalizability of the algorithm to different types of data or situations.
4. The potential for errors or biases in the algorithm.

By considering these factors and applying critical thinking skills, we can better understand the strengths and weaknesses of machine learning algorithms and their applications.

Michigan should spend the billions of dollars required to improve its fresh and storm water infrastructure, along the way creating thousands of new jobs and other economic dividends, according to a report from the advocacy group Environmental Entrepreneurs.

While expensive, E2 said Michigan's water infrastructure is so underfunded — $90 per capita lower than the U.S. average, according to Business Leaders for Michigan — that it's an impediment to job creation and new or expanding businesses, the report argues.

The report said investing an additional $12.2 billion in Michigan's own water infrastructure needs on top of existing expenditures would over the next two decades help create nearly 90,000 direct job-years in multiple industries while generating about $441.3 million in additional earned income for state residents annually.

E2 calls itself a national, nonpartisan advocacy group of business leaders, investors, and professionals from every sector of the economy who advocate for policies that are good for the economy and good for the environment. It is an affiliate of the Natural Resources Defense Council.

Michigan Gov. Gretchen Whitmer has advocated for investing in better roads and bridges, but also water and sewer systems. Whitmer created a Clean Water Public Advocate office and her Rebuild Michigan Plan says the state underfunds its water and sewer systems by $800 million a year.

Whitmer also has called for expedited replacement of old lead water lines in cities across the state. She said funds need to be raised to clean up contaminated groundwater and long-term funding of improvements for water delivery and sewer systems through the Rebuild Michigan Bank.

In a telephone press conference with reporters, Sen. Sean McCann, D–Kalamazoo, said the state Legislature needs to do more to fund water and sewer improvements. He said last year the Legislature approved a $120 million supplemental for water infrastructure and compliance in response to the PFAS, or perfluoroalkyl substances, contamination.

"Fresh water is part of our identity" as Michiganders with lakes and streams driving tourism and recreation opportunities, said McCann, adding that the E2 report confirms what everyone already knows. "We are not doing enough to keep Michigan families safe (from lead poisoning and PFAS). Every day we wait, the end costs get higher."

Flint's water crisis in 2014 taught the lesson of how improperly treated drinking water can hurt a community. After the public water supply was switched from Lake Huron to the Flint River and chemicals to ensure safe water weren't added to save money, lead leached into the water supply. Children were exposed to high concentrations of lead, a severe health hazard for growing bodies. The public health crisis cost at least $600 million with other untold other effects.

Rhonda Grayer, managing partner with WT Stevens Construction in Flint, said her company was one that responded to the Flint water crisis. The company employs 55 people, many of whom were underemployed or unemployed. She advocated for greater funding to improve water and sewer systems.

The E2 study recommended that increased spending over 20 years could create each year up to 4,500 direct jobs, more than 300 indirect jobs and more than 2,900 induced jobs. Over 20 years, E2 estimated nearly 90,000 direct, full-time job-years could be enjoyed.

The job is immense. Detroit's water and sewer system covers 6,400 miles. The state system is even greater, covering 150,000 miles of sewer, 38,000 miles of storm sewer pipe, 1.6 million inlets and catch basins, 725,000 manholes, 1.3 million septic systems, 500,000 lead service lines and 35,000 regulated county storm water drains, said the E2's report, "How Investing in Michigan's Water Infrastructure Protects Our Economy, Creates Jobs and Drives Growth."

Dayne Bartscht of the Eastern Market Brew Co. in Detroit said the 25-employee company operates a tap room and bar in Detroit and will soon open a tap room in Ferndale, hiring another 25 workers.

"Without clean water, our industry would not exist," Bartscht said, adding many businesses outside of Detroit are jealous of the city's good drinking water. "Some of it is not good. We had to replace a sewer tap that was made out of wood."

The American Society of Civil Engineers gives low grades for various Michigan water system components: drinking water (D), stormwater (D-) and wastewater (C).

One reason why the grades are so low is the system's age: In Detroit, approximately 80 percent of the city's combined water system's transmission and distribution infrastructure was installed prior to 1940. Other Michigan water systems date back a century.

Lesson: The History and Significance of Hand Signals in Baseball

Introduction:
Baseball is one of the most popular sports in the United States, with a rich history dating back to the 18th century. One of the most interesting aspects of baseball is the use of hand signals, which has been an integral part of the game since the late 19th century. In this lesson, we will explore the history and significance of hand signals in baseball, including their origins, development, and impact on the game.

Section 1: Origins of Hand Signals in Baseball

The use of hand signals in baseball can be traced back to the 1890s when a deaf ballplayer's coach started using hand signals to communicate with him during the game. This innovation allowed the player to know whether the previous pitch was a strike or a ball without relying on verbal communication. Over time, this practice became more widespread, and hand signals became an essential part of baseball strategy.

Question: Why were hand signals introduced in baseball?
Answer: Hand signals were introduced in baseball to help a deaf ballplayer understand the game better.

Section 2: Development of Hand Signals in Baseball

As baseball evolved over the years, so did the use of hand signals. Coaches and players began using hand signals to communicate with each other on the field, signaling plays, and strategies. This led to the development of a complex system of hand signals that is still used today. For example, some teams use hand signals to indicate whether a player should steal a base or not, depending on the situation.

Question: How has the use of hand signals changed over time?
Answer: The use of hand signals in baseball has evolved significantly over time, becoming more complex and sophisticated as the game has developed.

Section 3: Impact of Hand Signals on Baseball

Hand signals have had a significant impact on the game of baseball. They have become an essential part of baseball strategy, allowing players and coaches to communicate effectively on the field. Additionally, hand signals have played a role in some of the most famous moments in baseball history, such as the "Shot Heard Round the World" in 1951.

Question: What is the significance of hand signals in baseball?
Answer: Hand signals are significant in baseball because they allow for effective communication on the field and have played a role in some of the most iconic moments in baseball history.

Q:

Galois theory and the connection to prime numbers

Let $F \subseteq E $ be a finite Galois extension with $G =\operatorname{ gal}( E : F )$. If $p$ is a prime integer and $p \mid [ E : F ] $, show that there exists an intermediate field extension $F \subseteq K \subseteq E$ such that $[E:K] = p$.

A:

One has $|G|=[E:F]$, hence using Cauchy's theorem, there exists $H\leqslant G$ of cardinality $p$. Therefore, using Galois' correspondence, there exists an intermediate field $K(=E^H)$ such that $[E:K]=|H|$.

Lesson: Introduction to Galois Theory and its Connection to Prime Numbers

### Section 1: Introduction

Galois theory is a branch of mathematics that deals with the study of field extensions and their properties. It was first introduced by Évariste Galois in the early 19th century. One of the most important results in Galois theory is the Fundamental Theorem of Galois, which states that every finite field extension can be uniquely decomposed into a product of smaller field extensions, each of which is a cyclic extension generated by an element of the Galois group.

In this lesson, we will explore the connection between Galois theory and prime numbers. We will see that if a field extension has a prime number of elements, then there exists an intermediate field extension with the same number of elements.

### Section 2: The Fundamental Theorem of Galois

The Fundamental Theorem of Galois states that every finite field extension $E$ over a base field $F$ can be uniquely decomposed into a product of smaller field extensions, each of which is a cyclic extension generated by an element of the Galois group $G$. In other words, we have:

$E \cong F \times_F K_1 \times_F K_2 \times_F \cdots \times_F K_n$

where $K_i$ are distinct field extensions of $F$, and $n$ is the number of distinct intermediate fields.

Now, let's consider the case where the field extension $E$ has a prime number of elements, i.e., $[E:F] = p$ for some prime number $p$. According to the Fundamental Theorem of Galois, we can write:

$E \cong F \times_F K_1 \times_F K_2 \times_F \cdots \times_F K_n$

with $[E:F] = p$. Since $p$ is prime, the only divisors of $p$ are $1$ and $p$ itself. Thus, we have two possibilities:

1. $n = 1$, which means that $E \cong F \times K_1$, and $[E:F] = [K_1:F]$. In this case, $K_1$ is a cyclic extension of $F$ generated by an element of order $p$.

2. $n > 1$, which means that $E$ has more than one distinct intermediate field. In this case, there exists an intermediate field $K$ such that $[E:K] = p$.

Now, let's prove the second statement using Galois' correspondence.

### Section 3: Galois' Correspondence

Galois' correspondence is a powerful tool in Galois theory that relates the structure of a field extension to the structure of its Galois group. It states that there is a one-to-one correspondence between the subgroups of $G$ and the intermediate field extensions of $E$ over $F$. In other words, if $H$ is a subgroup of $G$, then $K(H) = E^H$ is an intermediate field extension of $E$ over $F$ with $[E:K(H)] = |H|$.

Now, let $p$ be a prime number dividing $[E:F]$. By the Fundamental Theorem of Galois, there exists an intermediate field extension $E \cong F \times_F K_1 \times_F K_2 \times_F \cdots \times_F K_n$ with $[E:F] = p$. Let $H \leqslant G$ be a subgroup of order $p$. By Galois' correspondence, there exists an intermediate field $K(H) = E^H$ such that $[E:K(H)] = |H| = p$.

Thus, we have shown that if a field extension has a prime number of elements, then there exists an intermediate field extension with the same number of elements.

### Conclusion

In this lesson, we have introduced the fundamental theorem of Galois and its connection to prime numbers. We have seen that if a field extension has a prime number of elements, then there exists an intermediate field extension with the same number of elements. This result has important applications in number theory, algebraic geometry, and cryptography.

Lesson: The Silk Roads

Introduction:
The Silk Roads were a network of trade routes that connected China with the Mediterranean world. They were used for centuries to transport goods, ideas, and people between different cultures. In this lesson, we will learn about the history of the Silk Roads, the goods that were traded, and the impact they had on the world.

Section 1: History of the Silk Roads

The Silk Roads were first established during the Han dynasty (206 BCE - 220 CE) in China. They were used to transport silk, a luxury fabric that was highly valued in the Mediterranean world. The routes expanded during the Tang dynasty (618 - 907 CE), when China experienced a period of prosperity and cultural exchange.

The Silk Roads were not just used for trade. They also facilitated the spread of ideas, religions, and technologies between different cultures. Buddhism, for example, was introduced to China via the Silk Roads.

Section 2: Goods Traded on the Silk Roads

The Silk Roads were used to transport a wide variety of goods, including silk, tea, spices, gold, and jade. These goods were often traded for other valuable items, such as precious metals, gems, and ivory.

Silk was the most famous good traded on the Silk Roads. It was produced in China and was highly valued in the Mediterranean world for its softness, durability, and beauty. Other important goods included tea, which was popular in both China and the Middle East, and spices, which were used for cooking and medicine.

Section 3: Impact of the Silk Roads

The Silk Roads had a significant impact on the world. They helped to connect different cultures and promote trade and economic growth. They also facilitated the spread of ideas, religions, and technologies between different regions.

One of the most significant impacts of the Silk Roads was the spread of Buddhism. Buddhist monks traveled along the routes to spread their religion, and many Chinese people embraced Buddhism as a result. The Silk Roads also helped to spread other religions, such as Christianity and Islam, between different regions.

Conclusion:
The Silk Roads were an important network of trade routes that connected China with the Mediterranean world. They played a significant role in promoting trade, economic growth, and cultural exchange between different cultures. By learning about the history of the Silk Roads, we can gain a better understanding of the world's interconnectedness and the importance of cultural exchange.

Simple test may help spot autism in infants: study

CHICAGO (Reuters) - A five-minute screening test could help detect autism in babies at 12 months of age, giving parents and doctors far more time to intervene, U.S. researchers said Thursday.

The study is the first to show that a simple screening tool could be used to detect autism in infants, said Dr. Lisa Gilotty, who heads the autism program at the National Institute of Mental Health, which funded the study.

"The benefit of this study is children get into treatment much earlier than they would otherwise," Karen Pierce of the University of California, San Diego, whose study will appear in the Journal of Pediatrics, said in a telephone interview.

Autism, a complex and mysterious brain disorder, strikes one in 110 children in the United States and affects four times as many boys as girls.

The disorder is characterized by difficulties in social interaction, communication and understanding other people's emotions and behavior.

It is usually first diagnosed in early childhood, around the age of 3, and recent studies have shown that the earlier that children are diagnosed and treated, the better they do.

"There is extensive evidence that early therapy can have a positive impact on the developing brain," Pierce said in a statement.

"The opportunity to diagnose and thus begin treatment for autism around a child's first birthday has enormous potential to change outcomes for children affected with the disorder."

For the study, Pierce and colleagues put together a network of 137 pediatricians in the San Diego area, who systematically started screening all babies at their one-year check up.

As part of the screening program, parents answered a survey, rating their babies on questions such as "When your child plays with toys, does he/she look at you to see if you are watching?" or "Does your child smile or laugh while looking at you?"

Any baby who failed the screening was referred to university's autism center for more testing. These children were re-tested every six months until age 3, when they were likely to show signs of autism.

Of the more than 10,000 infants, 184 failed the initial screening, and 75 percent of these children ended up with some problem. Of the total, 32 of the children have received an autism diagnosis, 56 had a language delay, nine were developmentally delayed and 36 were categorized as having some other issue.

After the screening program, all toddlers diagnosed with autism or developmental delay, and 89 percent of those with language delay were referred for behavioral therapy around the age 17 months. On average, these children began receiving treatment at 19 months.

"Those kids were getting treatment who otherwise may not have been seen for treatment until age 3 or later," Gilotty said in a telephone interview.

Dr. Chrystal de Freitas, a pediatrician who participated in the study, said parents who got the screening paid more attention to their child's development, and it helped prepare some for potentially bad news.

"In addition to giving me the opportunity to do a more thorough evaluation, it allowed parents time to process the information that their child might have a development delay or autism -- a message no parent wants to hear," she said in a statement.

Pierce said surveys of the doctors before the program showed that most had not been screening infants in any systematic way for autism. But after the study, 96 percent said they have continued using the screening tool.

Gilotty said the screening test still needs to be confirmed through other studies, but it proves that it is possible to systematically screen babies for autism in a way that does not put too much of a burden on pediatricians.

Republican Jeff Flake faced off with his Planned Parenthood opponents in a town hall meeting. He wasn't expecting to engage in an epic showdown with a teen.

President Trump signed a bill on Thursday that will deny health clinics that perform abortions from receiving Title X family-planning funds. Democrats and women's health advocates believe the signing of the bill will adversely impact low-income women to get the proper health care they need, including birth control and cancer screenings.

Before leaving office, Obama made sure to put into effect a rule that prevented states from discriminating against Planned Parenthood when it distributes funds for family planning services.

Now, Trump just reversed that rule.

So when privileged white men in positions of power make important decisions on behalf of women everywhere, it's a serious point of contention. And the GOP senator from Arizona was about to get an earful.

Foxx started off by making a clear distinction between herself and Flake. "I just want to state some facts,” she began. “I’m a young woman; you’re
a middle-aged man. I’m a person of color, and you’re white."

Lesson: The Importance of Reproductive Health Care

Introduction:
Reproductive health care is a fundamental human right that should be accessible to all individuals, regardless of their gender, age, or socioeconomic status. In this lesson, we will explore the importance of reproductive health care and the challenges faced by marginalized communities in accessing quality health services. We will also discuss the role of government policies in shaping access to reproductive health care and the potential consequences of these policies on individuals and society as a whole.

Section 1: Understanding Reproductive Health Care

Reproductive health care refers to the services that individuals need to maintain their reproductive health, including family planning, contraception, and prevention and treatment of sexually transmitted infections (STIs), among others. Reproductive health care is essential for several reasons:

1. It enables individuals to plan their families and have the number of children they desire.
2. It empowers individuals to take control over their reproductive lives and make informed decisions about their health.
3. It reduces maternal and infant mortality rates by ensuring access to quality prenatal care and delivery services.
4. It prevents the spread of STIs, including HIV, which can lead to severe health complications if left untreated.
5. It promotes gender equality by enabling individuals to participate equally in social, economic, and political spheres.

Section 2: Barriers to Accessing Reproductive Health Care

Despite the importance of reproductive health care, marginalized communities continue to face several barriers in accessing quality health services. These barriers include:

1. Lack of awareness and knowledge about reproductive health care services and their benefits.
2. Limited availability of health facilities and providers in rural and low-income areas.
3. High costs associated with seeking health care, including transportation, consultation fees, and medication costs.
4. Social stigma and cultural taboos surrounding reproductive health issues, which prevent individuals from seeking care.
5. Restrictive government policies that limit access to contraception and other reproductive health services.

Section 3: Government Policies and Their Impact on Reproductive Health Care

Governments play a crucial role in shaping access to reproductive health care through their policies and programs. Some governments have implemented policies that promote access to reproductive health care, while others have implemented policies that restrict access to these services. For example:

1. In the United States, the Affordable Care Act (ACA) requires insurance companies to cover contraception without any out-of-pocket costs to patients. However, the Trump administration has issued rules that allow employers to deny coverage for contraception based on religious or moral objections.
2. In Brazil, the government has implemented policies that promote access to contraception and other reproductive health services, leading to a significant reduction in maternal and infant mortality rates.
3. In some African countries, governments have implemented policies that restrict access to contraception and abortion, leading to high rates of unintended pregnancies and unsafe abortions.

Section 4: Critical Thinking Questions

1. How do social and economic factors influence access to reproductive health care?
2. What are the potential consequences of restrictive government policies on reproductive health care?
3. How can governments promote access to reproductive health care while respecting individuals' religious and moral beliefs?

Conclusion:
Reproductive health care is a fundamental human right that should be accessible to all individuals. Governments have a responsibility to implement policies that promote access to quality health services, while respecting individuals' rights and beliefs. By understanding the importance of reproductive health care and the barriers faced by marginalized communities, we can work towards a more equitable and just society.

1. Field of the Invention:
The present invention relates to an inverter used for driving a backlight of a liquid crystal display (LCD). More particularly, the present invention relates to a balance coil and an inverter for driving a plurality of Cold Cathode Fluorescent Lamps (CCFL) in parallel.
2. Description of the Related Art:
Current LCD displays require a backlight unit that is small in size and efficient. Consequently, CCFL is widely used as a light source of backlight unit. However, a single back light unit equipped with only one lamp is not sufficient for use in a wide-bodied display. Instead, multiple backlight units using a plurality of lamps are used because they better satisfy the requirements of a wide-bodied display.
In order to minimize cost and simplify structure, multiple backlight units drive the plurality of lamps in parallel. A conventional parallel driving circuit utilizes a balance coil for balancing currents in each lamp.
FIG. 1 is a schematic representation illustrating an inverter for driving a multiple backlight disposed with a balance coil, and FIG. 2 is a schematic representation illustrating a structure of a conventional balance coil.
Referring to FIGS. 1 and 2, an inverter includes a driving circuit 1, a transformer 2 for driving two fluorescent lamps LP1 and LP2, and a feedback control circuit 3.
Furthermore, the inverter includes balance coils 4 and 4′, respectively, connected to a lamp for balancing current flowing through a first lamp LP1 and a second lamp LP2. Ballast capacitors C1 and C2 are used for preventing the current flowing through each lamp LP1 and LP2 from increasing, and are connected in series to each lamp LP1 and LP2.
Referring to FIG. 2, the balance coils 4 and 4′ include a bobbin 11, a core 12 inserted into a groove 11a of the bobbin 11 and a coil 13 wrapped at an external side of the bobbin 11.
The current flowing through each lamp LP1 and LP2 is balanced between each lamp by the coils 4 and 4′. Thereby, the backlight unit is stably maintained without any luminance difference between the lamps.
However, in the conventional inverter, one balance coil 4 and ‘4’ is connected to each lamp LP1 and LP2, thus requiring a large number of balance coils. Therefore, because of the large number of balance coils used the conventional inverter is uneconomical and is large in size.
Furthermore, the conventional inverter uses ballast capacitors C1 and C2 to prevent a current increase in each lamp, and if the ballast capacitors are used, a high voltage is applied to both ends of the transformer 2 to the detriment of the transformer. Consequently, the use of ballast capacitors reduces the stability of the transformer.
Meanwhile, the conventional balance coils 4 and 4′ have a limitation in that by structurally increasing the size of the core 12 there is a high possibility of creating an inferior quality of goods due to core saturation.
Accordingly, there is a need for an improved inverter used for driving a backlight of a liquid crystal display (LCD) that is both small in size and economical.

Photoinactivation of microorganisms with sub-micromolar concentrations of imidazolium metallophthalocyanine salts.
The increasingly limited therapeutic options for the treatment of infections caused by multi-resistant Gram-negative bacteria due to the alarming increase in bacteria resistance, renewed interest in photodynamic inactivation (PDI) of bacteria. We address PDI of multi-resistant bacteria with a new family of cationic tetra-imidazolyl phthalocyanines bearing a diversity of cationizing alkylic chain sizes, degrees of cationization and coordinating metals. The antimicrobial activities of the phthalocyanines under white light against Gram-positive and Gram-negative bacteria have remarkable differences in efficacy. We relate their spectroscopic and photophysical properties with the generation of reactive oxygen species (ROS), biological performance and structural features. We show that sub-micromolar concentrations of a Zn(II) tetra-ethyl cationic phthalocyanine reduce colonies of Gram-negative bacteria (E. coli, P. aeruginosa) and C. albicans by 7 log units while leaving mammalian cells unharmed. This is a new lead to address hard-to-treat localized infections.

Lesson: Introduction to Formwork

### Section 1: Theoretical Concepts
Formwork is a temporary structure used to support and shape concrete while it is being poured. It must be strong enough to hold the weight of the concrete and withstand the pressure generated during the pouring process. High ribbed formwork is a type of formwork that has a ribbed surface, which provides additional strength and support to the concrete.

### Section 2: Practical Examples
High ribbed formwork is commonly used in construction projects where the concrete needs to have a smooth finish. It is also useful in situations where the concrete will be subjected to heavy loads or where there are complex shapes involved. For example, in the construction of a bridge, high ribbed formwork can be used to create the arches that support the weight of the bridge deck.

### Section 3: Real-World Scenarios
One real-world scenario where high ribbed formwork might be used is in the construction of a retaining wall. A retaining wall is a structure that holds back soil or other materials so that they don't slide down a slope. High ribbed formwork can be used to create the shape of the retaining wall, and then the concrete can be poured into the formwork to create a strong, durable structure.

### Glossary
- Formwork: A temporary structure used to support and shape concrete while it is being poured.

Targeting therapeutics to bone by conjugation with bisphosphonates.
Bisphosphonates target and bind avidly to the mineral (hydroxyapatite) found in bone. This targeting ability has been exploited to design and prepare bisphosphonate conjugate prodrugs to deliver a wide variety of drug molecules selectively to bones. It is important that conjugates be stable in the blood stream and that conjugate that is not taken up by bone is eliminated rapidly. The prodrugs should release active drug at a rate appropriate so as to provide efficacy. Radiolabelling is the best method to quantify and evaluate pharmacokinetics, tissue distribution, bone uptake and release of the active drug(s). Recent reports have described bisphosphonate conjugates derived from the antiresorptive drug, alendronic acid and anabolic prostanoid drugs that effectively deliver prostaglandins and prostaglandin EP4 receptor agonists to bone and show enhanced anabolic efficacy and tolerability compared to the drugs alone. These conjugate drugs can be dosed infrequently (weekly or bimonthly) whereas the free drugs must be dosed daily.

textbook:
Lesson Title: Targeting Therapeutics to Bone Using Bisphosphonates

Introduction:
Bisphosphonates are a class of drugs that are used to treat bone diseases such as osteoporosis, Paget's disease, and bone metastases from cancer. They work by inhibiting the activity of osteoclasts, which are cells that break down bone tissue. This helps to slow down bone loss and increase bone density. In this lesson, we will learn about how bisphosphonates can be conjugated with other therapeutic molecules to target them specifically to bone tissue.

Core Value:
The core value of this lesson is that bisphosphonates can be used as a delivery system for other therapeutic molecules, allowing them to be targeted specifically to bone tissue. This is important because it can help to improve the effectiveness of the treatment while reducing side effects.
