Kinetic characterization of ATP diphosphohydrolase and 5'-nucleotidase activities in cells cultured from submandibular salivary glands of rats.
The participation of ecto-ATP diphosphohydrolase (CD39; ecto-NTPDase) and ecto-5'-nucleotidase (CD73) activities in the nucleotide hydrolysis by salivary gland cells from rats was evaluated. We investigated the biochemical characteristics of these ectoenzymes in cells cultured from submandibular salivary glands of rats. The V(max) for the hydrolysis of ATP, ADP and AMP were 2275+/-153 (mean+/-SEM, n = 4), 941+/-96 (mean+/-SEM, n = 5) and 175+/-5 (mean+/-SEM, n = 5) nmol Pi liberated per min per mg of protein, respectively. The K(m) values for ATP, ADP and AMP were 224+/-8 microM (mean+/-SEM, n = 4), 163+/-15 microM (mean+/-SEM, n = 5) and 117+/-5 microM (mean+/-SEM, n = 5), respectively. The competition plot showed that ATP and ADP were hydrolyzed at the same active site on the enzyme. It may be postulated that the physiological role for this ecto-enzyme cascade is to terminate the action of the co-transmitter ATP, generating adenosine.

Lesson: Enzyme Activity and Kinetics

Introduction:
Enzymes are biological catalysts that speed up chemical reactions in living organisms. They play a crucial role in various biological processes, including metabolism, growth, and development. In this lesson, we will learn about enzyme activity and kinetics, focusing on the example of ATP diphosphohydrolase and 5'-nucleotidase activities in cells cultured from submandibular salivary glands of rats.

Section 1: Enzyme Activity

Topic 1: What is enzyme activity?
Enzyme activity refers to the rate at which an enzyme catalyzes a specific reaction. The higher the enzyme activity, the faster the reaction rate.

Topic 2: How is enzyme activity measured?
Enzyme activity can be measured using various methods, such as spectrophotometry, radiography, or chromatography. However, the most common method is to measure the change in absorbance or fluorescence of a substrate or product over time.

Section 2: Enzyme Kinetics

Topic 1: What is enzyme kinetics?
Enzyme kinetics is the study of how enzyme activity changes with varying conditions, such as temperature, pH, or substrate concentration. It involves determining the enzyme's maximum rate (Vmax) and Michaelis-Menten constant (Km).

Topic 2: How does temperature affect enzyme kinetics?
Temperature affects enzyme kinetics because it influences the rate of both enzyme-catalyzed reactions and non-enzymatic reactions. As the temperature increases, the enzyme's activity generally increases until it reaches its optimal temperature, after which the enzyme's activity decreases due to denaturation.

Topic 3: How does pH affect enzyme kinetics?
pH affects enzyme kinetics because it influences the ionization state of amino acid residues in the enzyme's active site. If the pH is too low or too high, the enzyme may lose its structure and function. Each enzyme has an optimal pH range where it functions most efficiently.

Section 3: Practical Examples

Topic 1: Ecto-ATP diphosphohydrolase and ecto-5'-nucleotidase activities in salivary gland cells from rats
In this study, researchers investigated the biochemical characteristics of ecto-ATP diphosphohydrolase and ecto-5'-nucleotidase activities in cells cultured from submandibular salivary glands of rats. They found that the Vmax for the hydrolysis of ATP, ADP, and AMP were 2275+/-153, 941+/-96, and 175+/-5 nmol Pi liberated per min per mg of protein, respectively.

Conclusion:
In this lesson, we learned about enzyme activity and kinetics, focusing on the example of ATP diphosphohydrolase and 5'-nucleotidase activities in cells cultured from submandibular salivary glands of rats. We discussed the importance of measuring enzyme activity, the basics of enzyme kinetics, and how factors such as temperature and pH affect enzyme activity. Finally, we applied these concepts to a practical example from the study.

Glossary:
- Enzyme: a biological catalyst that speeds up chemical reactions in living organisms
- Activity: the rate at which an enzyme catalyzes a specific reaction
- Kinetics: the study of how enzyme activity changes with varying conditions
- Vmax: the maximum rate of an enzyme-catalyzed reaction
- Km: the Michaelis-Menten constant, which represents the substrate concentration at which the reaction rate is half of Vmax
- Denaturation: the process by which an enzyme loses its structure and function due to high temperatures or other factors

To succeed, Microsoft’s new app store will need developers to build apps. Microsoft execs tossed out their best pitch yesterday.

When Microsoft launches Windows 8, its completely revamped operating system, next year, it will follow in Apple’s wake and unleash a store that will sell apps to run on its PCs.

And Microsoft wants app developers to know that it will be a very good store indeed–one that, among other things, allows developers who sell large numbers of apps to keep more of the revenues than the Apple store.

To that end, Microsoft held a preview of the upcoming Windows Store in San Francisco on Tuesday, which seemed designed to hammer this point home. “This is the biggest and most signficant developer opportunity ever,” said Antoine Leblond, Microsoft’s corporate vice president for Windows Web Services.

The store will launch with a limited number of apps as part of the Windows 8 beta, which Leblond said will begin in late February. For the store to succeed, Microsoft needs to convince developers to take on the burden of building versions of their apps for Windows 8, in addition to the versions they create for the Apple and Android markets.

Leblond reeled off all the reasons developers should be excited about the Windows Store. First is the size of the ecosystem: 1.25 billion PCs in the world use Windows, Leblond said, and half a billion licenses for Windows’ latest operating system, Windows 7, have been sold so far. In comparison, only 247 million tablets and phones run Android, and only 152 million devices have the iOS (the iPhone and iPad) operating system.

Windows offers “incredible, incredible reach,” Leblond told the developers in the audience. “That’s what you get to participate in by writing Metro-style apps.” (“Metro” is the name for apps written for the new Windows platform.)

advertisement

Microsoft says it will also allow developers to keep a bigger chunk of the pie. The Windows Store will use a 70/30 revenue split–the same as Apple and Android–but only up until the first $25,000 in sales. After than, Leblond said, Microsoft will reduce its share of the take to 20 percent and let developers keep the remaining 80 percent.

“We’re going to give you a bigger bite of the apple,” Leblond said, only slightly tongue-in-cheek.

The Windows Store will also save developers time by offering a “free trial” option that will allow customers to give apps a spin before deciding whether to buy.

That’s enormously attractive to app developers, Yash Bandla, a product manager for Sling Media, who was at the event, told Fast Company. It means developers will only have to build a single version of their apps. That capability doesn’t exist on iOS, so developers who want to give customers a taste of their apps have to build two versions: a free one and a paid one.

Leblond promised developers greater flexibility in managing in-app payments and in things like subscription management. The store will be global, available in 231 markets around the world and in 100 languages.

As for the approval process, Leblond said Microsoft will seek a happy medium between the Android free-for-all, which has led to problems with malware, and the Apple black box, which can take months to get approvals and leave developers in the dark when their apps are turned down.

advertisement

Leblond said the Windows Store will set a maximum app price of $999.99 (“because $1,000 is too much for an app”) and a minimum of $1.49.

Asked to explain the rationale for the minimum, Leblond told Fast Company that was due to calculations Microsoft had made about the minimum a developer would need to charge in order to break even on development costs.

“You can’t buy a song for 99 cents anymore,” he said. “$1.49 seemed like a reasonable price.”

This after Morente acted on the letter from Mines and Geosciences Bureau (MGB) regional director Edilberto Arreza over the issuance of cease and desist order against illegal small-scale miners operating in the area that is within the approved Mineral Production Sharing Agreement (MPSA) of Oro East.

“In this regard, provide necessary police assistance in carrying out the said order. Submit after activity report to reach this office after rendering assistance,” the regional police directive showed.

It was learned that the Oro East led by its operations manager Ruben Feliciano formally takes over the mining operations anytime Wednesday with the intervention of the Davao Oriental Provincial Police Office and the 10th Infantry Division under Brig. Gen. Ariel P. Bernardo.

Feliciano himself echoed a rejoinder letter addressed to Lorenzo A. Lomocso, the barangay captain of Tubaon, “to please assist the company in the implementation of the (cease and desist) order.”

In issuing its order, the MGB ordered stoppage of illegal small-scale gold mining activities in the area “for having no approved small-scale mining permit issued by the authorities concerned.”

This came after reports showed that illegal small-scale mining activities were very rampant in Barangay Tubaon to the detriment of the Oro East which was the sole mining company to have the approved permit to mine the area.

“But there is nothing to be alarmed of, especially to those small-scale miners, since we can reach into a win-win solution, that is, we will formulate mechanisms so that they cannot be dislocated and can still mine in the area and now legally,” Feliciano said.

He asked for their full cooperation as their company takes over because their presence is no longer a threat to their livelihood but a partner towards progress and development.

“My heart belongs to them. I know their sentiment. We are here to work together. We can sit down and discuss what we can drive at as long as we abide by the government’s policy on avoiding environmental degradation,” he said.

Feliciano said that for this purpose everybody involved in mining activities in the area can contribute to the growth of our economy since they can give taxes what are due for the government.

“You see, this is for the good of our economy and the government,” he said. (ASA)

text: To the editor:. Pennsylvania is one of only five states that have not passed measures to limit Joint and Several Liability.. Anyone in Pennsylvania who pays for liability insurance, whether it is automobile liability or business or personal liability, is paying more for this coverage because of the Joint and Several Liability Law.. The unfair doctrine of Joint and Several Liability can require a defendant who is found only 1 percent liable in a lawsuit to pay 100 percent of damages awarded. In other words those, who carry liability insurance or have the deep pockets may have to pay 100 percent of a person's injuries even though they were only 1 percent negligent. What is fair about this law?. Several months ago Gov. Ed Rendell vetoed Senate Bill 435 which would have reformed the Joint and Several Liability Law. What was he thinking?

Lesson: Understanding the Joint and Several Liability Law

## Introduction

In this lesson, we will explore the Joint and Several Liability Law in Pennsylvania. We will learn what this law is, why it exists, and how it affects people who carry liability insurance or have deep pockets. By the end of this lesson, you will be able to understand the importance of this law and how it impacts society.

## Section 1: What is the Joint and Several Liability Law?

The Joint and Several Liability Law is a legal principle that allows a plaintiff to recover damages from multiple defendants responsible for an injury. This means that if there are multiple parties responsible for an accident, the plaintiff can sue all of them and recover damages from any one of them. This law is designed to make it easier for plaintiffs to recover damages in cases where it is difficult to determine which defendant is responsible for the injury.

## Section 2: Why does the Joint and Several Liability Law exist?

The Joint and Several Liability Law exists to protect plaintiffs who have been injured due to the negligence of multiple defendants. It allows plaintiffs to recover damages from any one of the defendants responsible for their injury, regardless of the percentage of fault each defendant had. This law is intended to ensure that plaintiffs receive compensation for their injuries, even if it is difficult to determine which defendant is responsible.

## Section 3: How does the Joint and Several Liability Law affect people who carry liability insurance or have deep pockets?

The Joint and Several Liability Law can have a significant impact on people who carry liability insurance or have deep pockets. If a plaintiff sues multiple defendants and recovers damages, the insurance company or deep-pocketed individual may be responsible for paying 100% of the damages awarded, even if they were only 1% negligent. This means that insurance rates may increase for individuals who carry liability insurance, and deep-pocketed individuals may be at risk of losing a significant amount of money in lawsuits.

## Section 4: Debate Questions

1. Do you think the Joint and Several Liability Law is fair? Why or why not?
2. Should the law be changed to limit the amount of damages that can be recovered from deep-pocketed individuals or insurance companies?
3. How does the Joint and Several Liability Law impact the insurance industry?

## Conclusion

In conclusion, the Joint and Several Liability Law is an important legal principle that allows plaintiffs to recover damages from multiple defendants responsible for an injury. While this law may have some negative impacts on insurance rates and deep-pocketed individuals, it is essential in ensuring that plaintiffs receive compensation for their injuries. By understanding the importance of this law, we can better appreciate its impact on society.

Lesson: Understanding the Importance of Minimum Wage

Introduction:
Minimum wage is the lowest amount of money that employers are required by law to pay their employees per hour. It is designed to ensure that workers earn a fair wage for their labor and to prevent exploitation in the workplace. In this lesson, we will explore the importance of minimum wage and why it is essential for workers and society as a whole.

Section 1: Theoretical Concepts

Topic 1: What is minimum wage?
- Minimum wage is the lowest hourly wage that employers are required by law to pay their employees.
- It is designed to ensure that workers earn a fair wage for their labor and to prevent exploitation in the workplace.

Topic 2: Why do we have minimum wage?
- Minimum wage is intended to protect workers from being paid unfairly low wages.
- It helps to reduce income inequality and poverty by ensuring that workers earn enough to meet their basic needs.
- Minimum wage also helps to stimulate economic growth by putting more money into the hands of consumers who then spend more on goods and services.

Section 2: Practical Examples

Topic 1: How does minimum wage work in practice?
- Let's say you work at a fast food restaurant and your hourly wage is $7.50 per hour. If you work 40 hours per week, you would earn $300 before taxes. However, if the minimum wage is increased to $10 per hour, you would earn $400 per week. This increase in wages can help you pay for basic necessities like rent, food, and transportation.

Topic 2: Real-world scenario
- In 2018, the city of Seattle passed a law that gradually increased the minimum wage to $15 per hour by 2021. A study conducted by the University of Washington found that while the increase in minimum wage led to higher wages for low-income workers, it also led to job losses and reduced hours for some workers. This highlights the complexities of implementing minimum wage laws and the need for careful consideration when making changes to labor policies.

Section 3: Self-Debating Discussion

Topic 1: Should the minimum wage be increased?
- Yes, because it would help to reduce income inequality and poverty.
- No, because it could lead to job losses and reduced hours for some workers.
- Maybe, because it would depend on the specific circumstances and economic conditions of the region or country.

Glossary:
- Minimum wage: The lowest hourly wage that employers are required by law to pay their employees.
- Income inequality: The unequal distribution of income between individuals, households, or groups within a society.
- Poverty: The state of not having enough money to meet basic needs such as food, housing, and healthcare.

Conclusion:
In conclusion, minimum wage is an essential tool in the fight against income inequality and poverty. It ensures that workers are paid fairly for their labor and helps to stimulate economic growth. While there may be challenges and trade-offs associated with implementing minimum wage laws, the benefits generally outweigh the costs. By understanding the importance of minimum wage, we can advocate for fair labor practices and work towards a more just society.

Synthesis of three series of ruthenium tris-diimine complexes containing acridine-based π-extended ligands using an efficient "chemistry on the complex" approach.
The preparation and characterization of three series of novel ruthenium(ii) complexes are reported, each series differing by the nature of the ancillary ligands (2,2'-bipyridine - bpy, 1,10-phenanthroline - phen or 1,4,5,8-tetraazaphenanthrene - TAP). The third ligand was either the heptacyclic heterocycle dipyrido[3,2-a:2',3'-c]quinolino[3,2-h]phenazine (dpqp) substituted at position 12 by an hydroxyl (oxo), 2,2-dimethoxyethylamine (DMEA) or halogeno (Cl or Br) substituent, or the octacyclic dipyrido[3,2-a:2',3'-c]pyrido[2,3,4-de]quinolino[3,2-h]phenazine (dppqp), prepared by a multi-step "chemistry on the complex" strategy from [RuL2(oxo-dpqp)](PF6)2. The three steps, halogenation, substitution by a dimethoxyethylamino group and cyclization in trifluoroacetic acid, were performed in reasonable to high yields depending on the nature of the ancillary ligands. Isolation and purification processes were facilitated by the ability to switch the solubility of the complex from aqueous to organic solvents, depending on the counter-ion. All new complexes were fully characterized; in particular their absorption properties were compared by UV-vis spectroscopy. Finally, π-stacking properties induced by these extended ligands were studied by 1H NMR studies and quantum chemical calculations.

Introduction:
In this lesson, we will learn about the synthesis of ruthenium tris-diimine complexes containing acridine-based π-extended ligands. We will cover the preparation and characterization of these complexes, as well as the "chemistry on the complex" approach used to create them.

Section 1: Preparation and Characterization of Ruthenium Complexes

1.1 What are Ruthenium Complexes?
Ruthenium complexes are compounds that contain ruthenium ions bonded to other molecules. In this case, we will be focusing on ruthenium tris-diimine complexes containing acridine-based π-extended ligands.

1.2 Synthesis of Ruthenium Complexes
The synthesis of ruthenium tris-diimine complexes was achieved using an efficient "chemistry on the complex" approach. This approach involved three steps:

1. Halogenation: The first step involved the addition of a halogen (such as chlorine or bromine) to the complex.
2. Substitution by a dimethoxyethylamino group: The second step involved the replacement of a hydrogen atom on the complex with a dimethoxyethylamino group.
3. Cyclization in trifluoroacetic acid: The final step involved the cyclization of the complex in the presence of trifluoroacetic acid.

1.3 Characterization of Ruthenium Complexes
The characterization of the ruthenium complexes was done using various analytical techniques such as NMR spectroscopy, mass spectrometry, and X-ray crystallography. These techniques allowed researchers to determine the structure and properties of the complexes, including their chemical composition, molecular weight, and coordination environment.

Section 2: "Chemistry on the Complex" Approach

2.1 What is "Chemistry on the Complex" Approach?
The "chemistry on the complex" approach is a method used to synthesize complex molecules by performing chemical reactions directly on the target molecule. This approach is particularly useful when dealing with sensitive or reactive compounds that cannot be easily isolated or manipulated.

2.2 Advantages of "Chemistry on the Complex" Approach
The "chemistry on the complex" approach has several advantages over traditional synthesis methods, including:

1. Reduced risk of side reactions or contamination.
2. Improved control over the reaction conditions.

Lesson: Understanding Tax Investigations

Introduction:
Tax investigations are a common occurrence in many countries around the world. They are carried out by government agencies to ensure that individuals and companies pay the right amount of taxes they owe. In this lesson, we will learn about tax investigations, their purpose, and how they work.

Section 1: What is a Tax Investigation?
A tax investigation is a process carried out by government agencies to examine the financial records of individuals or companies to determine if they have paid the correct amount of taxes they owe. Tax investigations can be initiated for various reasons, including suspected tax evasion, fraud, or errors in tax returns.

Section 2: Purpose of a Tax Investigation
The primary purpose of a tax investigation is to ensure that individuals and companies pay the right amount of taxes they owe. Tax investigations help governments collect the revenue needed to provide essential services such as education, healthcare, and infrastructure. They also help prevent tax evasion, which is the deliberate avoidance of paying taxes by individuals or companies.

Section 3: How does a Tax Investigation work?
A tax investigation typically begins with a letter from the tax authority informing the individual or company that they are being investigated. The tax authority then requests financial records, such as bank statements, invoices, and receipts, to verify the accuracy of the tax return. If discrepancies are found, the tax authority may ask for additional information or documents. If the investigation finds that taxes were underpaid, the individual or company may be required to pay back taxes, plus penalties and interest.

Section 4: Examples of Tax Investigations
Tax investigations can happen to anyone, regardless of their income level or social status. Here are some examples of tax investigations:

1. In 2016, British singer and songwriter Ed Sheeran was investigated by the UK tax authority for allegedly not paying enough taxes on his income.
2. In 2017, American President Donald Trump was investigated by the US House Ways and Means Committee for not releasing his tax returns.

Section 5: Conclusion
In conclusion, tax investigations are an essential part of the tax system. They help ensure that individuals and companies pay the right amount of taxes they owe, prevent tax evasion, and provide essential services to the public. By understanding the purpose and process of tax investigations, we can better appreciate their importance in society.

Glossary:
- Tax Investigation: A process carried out by government agencies to examine the financial records of individuals or companies to determine if they have paid the correct amount of taxes they owe.
- Tax Evasion: The deliberate avoidance of paying taxes by individuals or companies.
- Penalties: Additional fines imposed on individuals or companies that underpay their taxes.
- Interest: The additional charge imposed on individuals or companies that underpay their taxes.

Self-Debating Discussion:
1. Why do you think tax investigations are necessary?
2. Can you think of any reasons why someone might try to avoid paying taxes?
3. How do tax investigations benefit society?

Q:

Isomorphisms between $\mathbb{R}^3$ and $\left( \mathbb{R}^3\right)^*$

Consider the oriented euclidean space $\mathbb{R}^3$. Every vector $A \in \mathbb{R}^3$ determines a $1$-form $ω^1_A$ by $ω^1_A(ξ)=(A,ξ), ξ\in \mathbb{R}^3$ (scalar product) and a $2$-form $ω^2_A$ by
\begin{equation}
ω^2_A(A,ξ_1,ξ_2)=(A,ξ_1,ξ_2) \text{*triple scalar product*}
\end{equation}
Show that the maps $A \to ω^1_A$ and $A \to ω^2_A$ establish isomoprhisms of the linear space $\mathbb{R}^3$  of vectors $A$ with the linear spaces of $1$-forms on $\mathbb{R}^3$ and the $2$-forms on $\mathbb{R}^3$. Then choose an orthonormal oriented coordinate system $(x_1,x_2,x_3)$ on $\mathbb{R}^3$ and show that:
\begin{align}
& ω^1_Α=A_1 x_1+A_2 x_2+A_3 x_3 \\
& ω^2_A=A_1 x_2\wedge x_3+A_2 x_1\wedge x_3+A_3 x_1\wedge x_2
\end{align}
I do understand the last two relations, since it can be proved that the set of linear coordinates $\{x_1,...,x_n\}=B$ is a basis for $\left( \mathbb{R}^n \right)^*$, therefore every $1$-form can be written as a linear combination of the elements of the basis, and moreover, I have already proved that every $2$-form can be written as a linear combination of the exterior product of elements of $B$, therefore like a linear combination of $1$-forms , exactly like $ω^2=\sum_{i<j}^n α_{ij}x_i \wedge x_j$.
I am not able to prove the first part, concerning the isomorphisms, plus I cant really see why does it have to be an orthonormal coordinate system. I am guessing just orthogonality will do fine as far as linear independece is concerned.
How can I prove the first part? Thanks.

A:

There is no need for orientations or bases to show that the two given (linear!) maps
$$\nu_1:\ A\ \longmapsto\ \omega_A^1\qquad\text{ and }\qquad \nu_2:\ A\ \longmapsto\ \omega_A^2,$$
are isomorphisms. The spaces of $1$-forms and $2$-forms are of dimensions $\tbinom{3}{1}=3$ and $\tbinom{3}{2}=3$, respectively. So to show that $\nu_1$ and $\nu_2$ are isomorphisms, it suffices to show that they are injective.

If $A\in\ker\nu_1$ then $\omega_A^1=0$, so in particular
$$\langle A,A\rangle=\omega_A^1(A)=0,$$
which shows that $A=0$ and hence $\nu_1$ is injective.
If $A\in\ker\nu_2$ then $\omega_A^2=0$, so for all $\xi_1,\xi_2\in\Bbb{R}^2$
$$\det(A,\xi_1,\xi_2)=\omega_A^2(\xi_1,\xi_2)=0,$$
which shows that $A=0$ and hence $\nu_2$ is injective.

For the relations to hold you don't need $\Bbb{R}^3$ to be oriented and you don't need $(x_1,x_2,x_3)$ to be an orthonormal basis for $\Bbb{R}^3$. What you do need is for $(x_1,x_2,x_3)$ to be the dual basis to whatever basis $(e_1,e_2,e_3)$ you choose for $\Bbb{R}^n$: If for all $A\in\Bbb{R}^3$ you have
$$\omega_A^1=A_1x_1+A_2x_2+A_3x_3,$$
then in particular for $A=e_i$ you get $\omega_{e_i}^1=x_i$ where $\omega_{e_i}^1(\xi)=\langle e_i,\xi\rangle$ for all $\xi\in\Bbb{R}^3$. This means precisely that $(x_1,x_2,x_3)$ is the dual basis to $(e_1,e_2,e_3)$.
When $(x_1,x_2,x_3)$ is the dual basis to $(e_1,e_2,e_3)$ then verifying the two relations is a matter of checking that they hold on any basis for $\Bbb{R}^3$. This is easiest for $(e_1,e_2,e_3)$; for $A=e_1$ we get
\begin{eqnarray*}
A_1x_1(\xi)+A_2x_2(\xi)+A_3x_3(\xi)=x_1(\xi)
&=&\langle e_1,\xi\rangle=\omega_{e_1}^1(\xi).\\
&\ &\\
A_1x_2\wedge x_3(\xi_1,\xi_2)+A_2x_1\wedge x_3(\xi_1,\xi_2)+A_3x_1\wedge x_2(\xi_1,\xi_2)
&=&x_2\wedge x_3(\xi_1,\xi_2)\\
&=&\begin{vmatrix}x_2(\xi_1)&x_3(\xi_1)\\ x_2(\xi_2)&x_3(\xi_2)\end{vmatrix}\\
&=&\begin{vmatrix}
 1&0&0\\
 x_1(\xi_1)&x_2(\xi_1)&x_3(\xi_1)\\
 x_2(\xi_2)&x_2(\xi_2)&x_3(\xi_2)
\end{vmatrix}\\
&=&\omega_{e_1}^2(\xi_1,\xi_2),
\end{eqnarray*}
for all $\xi,\xi_1,\xi_2\in\Bbb{R}^3$, and the same argument works for $e_2$ and $e_3$, of course.

Lesson: Linear Algebra - Isomorphisms between $\mathbb{R}^3$ and $\left( \mathbb{R}^3\right)^*$

**Objective:** To understand the concept of isomorphisms and their application in linear algebra.

**Prerequisites:** Basic knowledge of linear algebra, including vectors, matrices, and linear transformations.

**Materials:** Paper, pencil, and a calculator.

**Introduction:** In this lesson, we will explore the concept of isomorphisms between two linear spaces. We will use the example of isomorphisms between $\mathbb{R}^3$ and $\left( \mathbb{R}^3\right)^*$.

**Section 1: What are isomorphisms?**

An isomorphism is a linear transformation that establishes a bijective correspondence between two linear spaces. In other words, it is a function that preserves the structure of the spaces while maintaining a one-to-one relationship between them.

**Section 2: Isomorphisms between $\mathbb{R}^3$ and $\left( \mathbb{R}^3\right)^*$**

Consider the oriented euclidean space $\mathbb{R}^3$. Every vector $A \in \mathbb{R}^3$ determines a $1$-form $ω^1_A$ by $ω^1_A(ξ)=(A,ξ), ξ\in \mathbb{R}^3$ (scalar product) and a $2$-form $ω^2_A$ by
\begin{equation}
ω^2_A(A,ξ_1,ξ_2)=(A,ξ_1,ξ_2) \text{*triple scalar product*}
\end{equation}
The maps $A \to ω^1_A$ and $A \to ω^2_A$ establish isomorphisms of the linear space $\mathbb{R}^3$ of vectors $A$ with the linear spaces of $1$-forms on $\mathbb{R}^3$ and the $2$-forms on $\mathbb{R}^3$.

**Section 3: Coordinate representation of the forms**

Now, let's choose an orthonormal oriented coordinate system $(x_1,x_2,x_3)$ on $\mathbb{R}^3$. Then we have:

\begin{align}
& ω^1_Α=A_1 x_1+A_2 x_2+A_3 x_3 \\
& ω^2_A=A_1 x_2\wedge x_3+A_2 x_1\wedge x_3+A_3 x_1\wedge x_2
\end{align}

These equations show that the coordinate representation of the forms is given by the linear combinations of the elements of the basis.

**Section 4: Exercises**

1. Prove that the maps $A \to ω^1_A$ and $A \to ω^2_A$ establish isomorphisms of the linear space $\mathbb{R}^3$ of vectors $A$ with the linear spaces of $1$-forms on $\mathbb{R}^3$ and the $2$-forms on $\mathbb{R}^3$.

2. Show that the coordinate representation of the forms is given by the linear combinations of the elements of the basis.

3. Find the coordinate representation of the exterior product of elements.

**Conclusion:** In this lesson, we have explored the concept of isomorphisms between two linear spaces using the example of isomorphisms between $\mathbb{R}^3$ and $\left( \mathbb{R}^3\right)^*$. We have seen how these isomorphisms can be used to relate vectors and forms, and we have also looked at some practical examples. This knowledge can be applied in various fields of mathematics and science, where linear transformations and isomorphisms play a crucial role.

## Lesson: Four Things That Contribute to Success in Your Career

### Introduction
 In this lesson, we will explore the four things that contribute to success in your career as revealed by Martin Lewis, a British journalist and television presenter. We will cover the importance of self-awareness, the need to prioritize your well-being, the significance of focusing on your chosen path, and the value of hard work and dedication.

### Section 1: Self-Awareness
Self-awareness is the first step towards success in your career. It involves understanding your strengths, weaknesses, values, and interests. This knowledge helps you make informed decisions about your career and avoid pursuing paths that are not aligned with your goals. To develop self-awareness, you can take personality tests, seek feedback from others, and reflect on your experiences.

**Theoretical Concept:** Self-awareness is the ability to understand one's own emotions, strengths, weaknesses, values, and interests.

**Practical Example:** If you are considering a career in finance, taking a personality test that measures your aptitude for math and analytical thinking can help you determine if this path aligns with your strengths.

**Real-World Scenario:** A young professional realizes that she dislikes working long hours and prefers a more balanced lifestyle. She decides to focus on finding a job that offers flexible hours and a healthy work-life balance.

### Section 2: Well-Being
Your well-being is just as important as your career success. It includes your physical, mental, and emotional health. Prioritizing your well-being can lead to increased productivity, creativity, and resilience. To maintain your well-being, you should exercise regularly, eat healthily, get enough sleep, and practice stress-reducing activities such as meditation or yoga.

**Theoretical Concept:** Well-being refers to an individual's overall physical, mental, and emotional health.

**Practical Example:** If you work long hours, you can schedule regular breaks throughout the day to reduce stress and maintain focus.

**Real-World Scenario:** An executive realizes that her work-life balance has been negatively impacted by her demanding job. She decides to delegate tasks and set boundaries to ensure that she has time for her family and personal hobbies.

### Section 3: Focus and Dedication
To succeed in your career, you must choose a specific path and become an expert in that field. The narrower your focus, the better you will be at it. This specialization allows you to stand out from the competition and command higher salaries. To achieve this level of expertise, you must be dedicated to continuous learning and improvement.

**Theoretical Concept:** Focus refers to the act of directing your attention towards a specific goal or task.

**Practical Example:** If you want to become a data scientist, you should focus on developing your skills in statistics, programming, and machine learning.

**Real-World Scenario:** A marketing professional decides to specialize in social media advertising and spends several hours each week studying the latest trends and strategies in the field.

### Glossary
- **Self-awareness:** Understanding one's own emotions, strengths, weaknesses, values, and interests.
- **Well-being:** An individual's overall physical, mental, and emotional health.
- **Focus:** Directing one's attention towards a specific goal or task.

### Conclusion
In conclusion, success in your career requires self-awareness, prioritization of well-being, focus on a specific path, and dedication to continuous learning and improvement. By following these four principles, you can achieve excellence in your chosen field and lead a balanced life.

This invention relates in general to polyimide foam structures and, more particularly, to methods of reshaping polyimide foam sheets into self-supporting structures of desired shapes.
Polyimide and modified polyimide foams are manufactured by a number of different processes. Typical are those described in our prior U.S. Pat. Nos. 4,407,980 and our co-pending U.S. patent applications Ser. No. 678,992 filed Dec. 6, 1984 and Ser. No. 556,604, filed Feb. 14, 1985. Also typical are U.S. Pat. No. 4,315,076 filed Apr. 16, 1981, U.S. Pat. No. 4,361,453 filed May 11, 1981 assigned to International Harvester and Monsanto respectively.
In one method, polyimide precursors are prepared by reacting a tetracarboxylic acid dianhydride or its half ester with a diamine, then heating the precursor in a thermal over to cause the material to expand into a foam while forming the polyimide. A large block or bun of foam is produced.
Another method of preparing polyimide foams involves reacting an imidocaproic acid monomer with a diamine. The imidocaproic acid monomer is prepared by reacting a tetracarboxylic acid dianhydride with caprolactam in a ratio of dianhydride to caprolactam of less than about 1:1.5. The resulting polyimide powder is caused to foam by heating it to a temperature in the range of about 150.degree. to 320.degree. C. in a square mold. The resulting foam bun is then cut into slabs or sheets of desired thickness.
In some cases it is possible to directly foam the polyimide to the desired sheet thickness. However, in most cases the resulting sheet has an excessively irregular upper surface, so that it is usually preferred to slice sheets from a larger block to obtain highly uniform sheets of the selected thickness.
Polyimide foam sheets have a large number of applications which take advantage of their flexibility and flame resistance, such as seat cushions in aircraft. Other applications such as insulating air ducts in aircraft, spacecraft, naval ships, etc., which need the flame resistance and lack of toxic gases when exposed to flame for the protection of passengers and personnel require a variety of foam configurations. Wrapping ducts with sheets is often not satisfactory, since the elastic characteristics of the sheets cause them to come loose and they are difficult to bend around sharp corners. Such sheets also are not adaptable to requirements for varying thicknesses, often are moisture permeable and have low surface strength.
Attempts have been made to foam the polyimide in a mold, such as a half-pipe, having a desired final configuration. This has been, unfortunately, found to produce structures of greatly varying density and poor mold filling, especially with molds having relatively thin areas. The structures produced by this method have been found to have local weak areas and to not retain their final shapes well. It is very difficult to obtain a desired density and strength uniformity (or selected density and strength gradients) in structures made by this method.
Thus, there is continuing need for improved methods of re-shaping polyimide foam sheets into desired shapes. Improvements are needed in density and strength uniformity. The shapes should be easily made, using standard foam sheets as the starting material. The ability to produce structures which are strong and retain their molded shape out of the mold is needed. A method which permitted forming foam structures having areas of different thicknesses and selected densities would be particularly useful.

Getting down to business at 2016 BETA conference

“The Bottom Line” was the theme of this year’s British Equestrian Trade Association Conference, held for the first time at the Woodland Grange Hotel, near Coventry, on Monday 7 November. Delegates from across the UK gathered to network with colleagues and listen to expert advice and handy tips from a panel of top-flight business professionals.

Vale Brothers' managing director, Peter Wilkes, was first to take the podium, speaking about his self-imposed challenge to jump a 70cm fence after only 10 riding lessons. His ambitious quest was inspired by a presentation on rider participation at last year's conference. The self-confessed adrenaline junky said that the achievement had left him looking for another equestrian adventure.

Ray Armes, founder of creative agency Touch of Mojo, explored the concept of building a brand and urged delegates to use theirs as a lighthouse to reveal their views about the world, rather than focusing solely on the products they offer.

Solicitor Nellie Jackson, of Birketts, talked about protecting a brand in terms of intellectual property rights and provided a set of practical tips to help avoid problems in this complex area.

Political commentator John Arnold, of Tweetminster, put Brexit and Article 50 under the conference spotlight in a frank discussion on the political climate as the UK faces separation from the European Union.

Danielle Olding, a leadership consultant and coach at From the Neck Up, provided advice to managers on the importance of keeping their staff motivated to ensure a thriving, successful business.

Accountant Matthew Osbourne, of Armstrong Watson, put profit and cash flow under the spotlight and dished out some helpful tips on improving them, while SEIB’s Caroline Garrow raised the worrying issue of cyber crime and highlighted that last year alone saw 75 per cent of small businesses affected by this growing problem.

“‘The Bottom Line' theme has certainly proved extremely popular among delegates,” said BETA executive director Claire Williams. ”Our speakers provided some extremely informative – and entertaining – presentations that were spot on and we've been really pleased with the feedback to date.”

Topic 1: Clear Vision, Mission, and Values
- A brand is more than just a logo or a slogan. It represents the essence of a company and what it stands for.
- A clear vision, mission, and values are essential to building a strong brand. They provide direction and purpose for the company and help to guide decision-making.
- A company's vision, mission, and values should be communicated to employees, customers, and stakeholders to create a sense of unity and purpose.

Topic 2: Differentiation and Positioning
- Building a brand helps to differentiate a company from its competitors and create a unique identity in the market.
- A brand's positioning refers to how it is perceived by its target audience relative to its competitors.
- A well-positioned brand can attract customers and create a loyal following.

Section 2: The Role of Branding in Business

Topic 1: Attracting Customers
- Branding plays a crucial role in attracting customers and creating a positive image of the company.
- A strong brand can create trust and credibility, which can lead to increased customer loyalty and repeat business.
- Customers are more likely to choose a brand they recognize and trust over a competitor.

Topic 2: Increasing Revenue
- A strong brand can increase revenue by attracting more customers and charging higher prices.
- A well-known brand can command a premium price, as customers are willing to pay more for a product or service that they perceive as being of higher quality.
- Branding can also help to increase sales by creating a sense of urgency and scarcity, which can drive customers to buy products or services before they become unavailable.

Section 3: Building a Strong Brand

Topic 1: Consistency

A photophoretic-trap volumetric display.
Free-space volumetric displays, or displays that create luminous image points in space, are the technology that most closely resembles the three-dimensional displays of popular fiction. Such displays are capable of producing images in 'thin air' that are visible from almost any direction and are not subject to clipping. Clipping restricts the utility of all three-dimensional displays that modulate light at a two-dimensional surface with an edge boundary; these include holographic displays, nanophotonic arrays, plasmonic displays, lenticular or lenslet displays and all technologies in which the light scattering surface and the image point are physically separate. Here we present a free-space volumetric display based on photophoretic optical trapping that produces full-colour graphics in free space with ten-micrometre image points using persistence of vision. This display works by first isolating a cellulose particle in a photophoretic trap created by spherical and astigmatic aberrations. The trap and particle are then scanned through a display volume while being illuminated with red, green and blue light. The result is a three-dimensional image in free space with a large colour gamut, fine detail and low apparent speckle. This platform, named the Optical Trap Display, is capable of producing image geometries that are currently unobtainable with holographic and light-field technologies, such as long-throw projections, tall sandtables and 'wrap-around' displays.

Lesson: Introduction to Photophoretic-Trap Volumetric Display

### Section 1: What is a Photophoretic-Trap Volumetric Display?

A photophoretic-trap volumetric display is a type of display that creates luminous image points in space, allowing them to be visible from almost any direction. These displays are capable of producing three-dimensional images without the need for physical boundaries or edges, making them different from other types of volumetric displays.

### Section 2: How does a Photophoretic-Trap Volumetric Display work?

A photophoretic-trap volumetric display works by using photophoretic optical trapping to suspend a cellulose particle in mid-air. This is achieved by creating a trap using spherical and astigmatic aberrations, which cause the particle to be attracted to a specific point in space. The trap and particle are then scanned through a display volume while being illuminated with red, green, and blue light. The result is a three-dimensional image that appears to float in mid-air.

### Section 3: Applications of Photophoretic-Trap Volumetric Display

Photophoretic-trap volumetric displays have many potential applications, including:

1. Advertising: Companies could use these displays to create eye-catching advertisements that appear to float in mid-air.
2. Entertainment: Movie theaters could use these displays to create immersive experiences for their customers.
3. Education: Teachers could use these displays to create interactive and engaging lessons for their students.
4. Art: Artists could use these displays to create stunning visual art pieces that appear to defy gravity.

### Glossary:
- Photophoresis: The process by which particles are attracted to a light source due to the radiation pressure exerted on them.
- Optical trap: A device that uses light to trap particles in mid-air.
- Volumetric display: A display that creates luminous image points in three-dimensional space.
- Persistence of vision: The phenomenon where an image continues to be perceived after the source of light has been removed or the observer has ceased looking at it.
- Aberration: A deviation from the ideal shape of a lens or mirror, causing distortion in the image produced.

### Conclusion:
In this lesson, we learned about photophoretic-trap volumetric displays and how they work. We also explored some potential applications for this technology and discussed some key terms related to it. By understanding the principles behind these displays, we can begin to imagine new ways to use them and push the boundaries of what is possible with three-dimensional displays.

Q:

Use statement For to write in a Tuple

I use this code to send midi sysEx. It s perfect for sending "fix" data but now i need to send data with different size.
            var midiPacket:MIDIPacket = MIDIPacket()
            midiPacket.length = 6
            midiPacket.data.0 = data[0]
            midiPacket.data.1 = data[1]
            midiPacket.data.2 = data[2]
            midiPacket.data.3 = data[3]
            midiPacket.data.4 = data[4]
            midiPacket.data.5 = data[5]
            //...
            //MIDISend...

Now imagine i have a String name "TROLL" but the name can change.
I need something like this :
            var name:String = "TOTO"
            var nameSplit = name.components(separatedBy: "")
            var size:Int = name.count

            midiPacket.length = UInt16(size)

            for i in 0...size{
                midiPacket.data.i = nameSplit[i]
            }
            //...
            //MIDISend...

But this code don t work because i can t use "i" like this with a tuple.
If someone knows how to do that.
Thanks in advance.
KasaiJo

A:

C arrays are imported to Swift as tuples. But the Swift compiler
preserves the memory layout of imported C structures (source), therefore you can rebind a pointer to the tuple
to an pointer to UInt8:
withUnsafeMutablePointer(to: &midiPacket.data) {
    $0.withMemoryRebound(to: UInt8.self, capacity: MemoryLayout.size(ofValue: midiPacket.data)) {
        dataPtr in // `dataPtr` is an `UnsafeMutablePointer<UInt8>`

        for i in 0..<size {
            dataPtr[i] = ...
        }
    }
}

Lesson: How to Use Tuples in Swift

Introduction:
In this lesson, we will learn about tuples in Swift. A tuple is a data structure that contains multiple values of different types. We can use tuples to store and pass around data in our programs.

Core Value:
The core value of this lesson is to understand how to use tuples in Swift.

Section 1: What are Tuples?
Tuples are a data structure in Swift that allow us to store multiple values of different types in a single variable. Tuples are useful when we want to store and pass around data in our programs without having to declare separate variables for each value.

Section 2: Creating Tuples
We can create tuples by enclosing multiple values in parentheses and separating them by commas. Here's an example:
```
let myTuple = (1, "Hello", true)
```
In this example, `myTuple` is a tuple containing the values `1`, `"Hello"`, and `true`.

Section 3: Accessing Values in Tuples
To access values in tuples, we use the `getter` method on the tuple. Here's an example:
```
let myTuple = (1, "Hello", true)
if let firstValue = myTuple.0 {
    print("The first value is \(firstValue)")
}
if let secondValue = myTuple.1 {
    print("The second value is \(secondValue)")
}
if let thirdValue = myTuple.2 {
    print("The third value is \(thirdValue)")
}
```
In this example, we use the `getter` method on `myTuple` to access the values inside the tuple.

Section 4: Using Tuples in Functions
We can use tuples to return multiple values from a function. Here's an example:
```
func calculateAreaAndPerimeter(width: Double, height: Double) -> (Double, Double) {
    let area = width * height
    let perimeter = 2 * (width + height)
    return (area, perimeter)
}
```
In this example, `calculateAreaAndPerimeter` returns a tuple containing the area and perimeter of a rectangle.

Section 5: Practice
1. Create a tuple containing the values `3.14`, `"pi"`, and `true`.
2. Access the first value in the tuple created in practice 1.
3. Define a function that takes two integers as arguments and returns a tuple containing their sum and product.

Conclusion:
In this lesson, we learned about tuples in Swift and how to use them to store and pass around data. We covered creating tuples, accessing values in tuples, using tuples in functions, and practiced with some examples. By applying these concepts, we can write more efficient and organized code.

Glossary:
- Tuple: A data structure in Swift that contains multiple values of different types.
- Getter: A method used to access values in tuples.
- Function: A block of code that performs a specific task.
