Genotype-specific clinical manifestation in long QT syndrome.
The congenital form of long QT syndrome (LQTS) is characterized by QT prolongation in the electrocardiogram (ECG) and a polymorphic ventricular tachycardia, Torsade de Pointes (TdP) mainly as a result of an increased sympathetic tone during exercise or mental stress. Recent genetic studies have so far identified seven forms of congenital LQTS caused by mutations in genes of the potassium and sodium channels or membrane adapter located on chromosomes 3, 4, 7, 11, 17 and 21. It is of particular importance to examine the genotype-phenotype correlation, especially in the LQT1, LQT2 and LQT3 forms of LQTS, which make up more than 90% of genotyped patients with LQTS, because it would enable us to manage and treat genotyped patients more effectively.

Lesson: Genotype-specific clinical manifestation in long QT syndrome

### Overview
In this lesson, we will learn about the genotype-specific clinical manifestation in long QT syndrome. We will cover the following topics:

1. What is Long QT Syndrome?
2. Types of Long QT Syndrome
3. Genotype-Phenotype Correlation
4. Clinical Manifestation of Long QT Syndrome
5. Management and Treatment of Long QT Syndrome
6. Glossary

### What is Long QT Syndrome?
Long QT Syndrome is a rare genetic disorder that affects the heart's electrical activity. It is characterized by a prolonged QT interval on the electrocardiogram (ECG), which can lead to an increased risk of developing abnormal heart rhythms called arrhythmias, particularly Torsade de Pointes (TdP).

### Types of Long QT Syndrome
There are several types of Long QT Syndrome, which are caused by mutations in different genes. These types include:

1. LQT1 - caused by mutations in the KCNQ1 gene
2. LQT2 - caused by mutations in the KCNH2 gene
3. LQT3 - caused by mutations in the KCNJ2 gene
4. LQT4 - caused by mutations in the SCN5A gene
5. LQT5 - caused by mutations in the KCNE1 gene
6. LQT6 - caused by mutations in the KCNE2 gene
7. LQT7 - caused by mutations in the KCNJ5 gene

### Genotype-Phenotype Correlation
The genotype-phenotype correlation refers to the relationship between the specific genetic mutation and the clinical manifestation of Long QT Syndrome. This relationship is important because it can help doctors better understand and manage the condition in patients who have been genotyped.

### Clinical Manifestation of Long QT Syndrome
The clinical manifestation of Long QT Syndrome can vary depending on the type of mutation a patient has. However, there are some common symptoms that are seen in all types of Long QT Syndrome, including:

1. Prolonged QT interval on ECG
2. Torsade de Pointes (TdP) - a life-threatening arrhythmia that can cause sudden death
3. Syncope (fainting)
4. Seizures
5. Palpitations
6. Exercise-induced collapse

### Management and Treatment of Long QT Syndrome
The management and treatment of Long QT Syndrome depends on the severity of the condition and the specific genetic mutation involved. Some common treatment options include:

1. Medications - such as beta-blockers, which can help to stabilize the heart rhythm
2. Implantable devices - such as an implantable cardioverter-defibrillator (ICD), which can detect and treat life-threatening arrhythmias
3. Lifestyle modifications - such as avoiding triggers like exercise or stress, and maintaining a healthy weight
4. Regular follow-up with a healthcare provider - to monitor the condition and adjust treatment as needed

### Glossary

| Term | Definition |
| --- | --- |
| Long QT Syndrome | A rare genetic disorder that affects the heart's electrical activity, characterized by a prolonged QT interval on the ECG |
| QT interval | A measurement on the ECG that represents the time it takes for the heart to contract and then refill with blood |
| Torsade de Pointes | A life-threatening arrhythmia that can cause sudden death |
| Genotype | The specific genetic mutation that a person has |
| Phenotype | The clinical manifestation of a genetic condition |
| Implantable cardioverter-defibrillator | A device that is implanted in the chest to detect and treat life-threatening arrhythmias |

### Conclusion

Understanding the genotype-phenotype correlation in Long QT Syndrome is crucial for effective management and treatment of patients with this condition. By examining the specific genetic mutation involved, healthcare providers can better understand the clinical manifestation and develop personalized treatment plans for their patients.

Lesson: How to Create a Sales Report

Introduction:
In this lesson, we will learn how to create a sales report that displays the total sales for a specific period of time. We will use a sample dataset to demonstrate the steps involved in creating a sales report.

Core Value:
The core value of this lesson is to teach students how to create a sales report that displays the total sales for a specific period of time.

Section 1: Creating a Sales Report

Step 1: Define the Report Field
- A sales report displays the total sales for a specific period of time.
- To create a sales report, we need to define the report field.
- The report field is the area where we will display the sales data.

Step 2: Choose the Report Period
- The report period is the duration of time that we want to display in the sales report.
- We can choose any period of time, such as a week, month, or year.
- For example, we can choose to display the sales data for the last two years.

Step 3: Preview the Report
- Once we have defined the report field and chosen the report period, we can preview the report.
- The report will display the total sales for the specified period of time.
- We can view the report in a window that appears on our screen.

Section 2: Analyzing the Sales Data

Step 1: Interpret the Sales Data
- After we have created the sales report, we need to interpret the data.
- We can analyze the data to identify trends and patterns.
- For example, we can look at the number of orders and the total sales for each month.

Step 2: Draw Conclusions
- Based on our analysis, we can draw conclusions about the sales data.
- We can use these conclusions to make informed decisions about our business.
- For example, if we see that sales are highest in a certain month, we can plan marketing campaigns around that time.

Section 3: Applying the Skills

Step 1: Use the Sales Data
- Once we have created and analyzed the sales report, we can use the data to make informed decisions.
- We can use the data to identify areas where we can improve our sales.
- For example, if we see that sales are lowest in a certain month, we can plan promotions or discounts to increase sales.

Step 2: Create Additional Reports
- We can use the skills we have learned to create additional reports.
- For example, we can create a report that displays the total revenue for a specific period of time.
- We can also create reports that display data from other areas of our business, such as inventory or customer service.

Conclusion:
In this lesson, we have learned how to create a sales report that displays the total sales for a specific period of time. We have also learned how to analyze the data and use it to make informed decisions. By applying the skills we have learned, we can create additional reports and use them to improve our business.

Utah delays asking Supreme Court to stop same-sex marriages

About 1,500 people gathered in Salt Lake City on Monday to celebrate marriage equality after a federal judge declined to stay his ruling that legalized same-sex marriage in Utah,

About 1,500 people gathered in Salt Lake City on Monday to celebrate marriage equality after a federal judge declined to stay his ruling that legalized same-sex marriage in Utah, (Tom Smart / The Deseret News/ AP)

Timothy M. Phelps and David Lauter

WASHINGTON -- It will likely be several days before Utah asks the U.S. Supreme Court to stop same-sex marriages in the state, the Utah attorney general’s office said Thursday.

The state had been expected to file a petition with the court as early as Thursday in a last-ditch effort to halt the weddings that have occurred since a federal judge struck down the state’s ban on such unions last week.

But the attorney general's website posted a notice that said outside lawyers need to be consulted before filing.

“The Attorney General’s Office is preparing an application to the United States Supreme Court requesting a stay of the district court’s order,” the notice said. “Due to the necessity of coordination with outside counsel the filing of the appeal may be delayed for a few days. It is the intent of the Attorney General’s Office to file with the Supreme Court as soon as possible.”

The state’s petition would go to Justice Sonia Sotomayor, who has jurisdiction over cases coming from Utah and neighboring states. She would likely refer the issue to her colleagues. There’s no deadline for the justices to make a decision, but they typically act quickly on such requests.

Last Friday, U.S. District Judge Robert Shelby ruled that Utah’s constitutional amendment limiting marriage to opposite-sex couples, which voters passed in 2004, violated the U.S. Constitution’s guarantee of equal protection of the laws.

His ruling was the first to hold that the Constitution guarantees same-sex couples the right to marry since last summer’s Supreme Court rulings, which took a significant, but limited, step in that direction.

State officials asked Judge Shelby to put his ruling on hold until a federal appeals court could review the case, saying it would cause a “chaotic situation.” When Shelby declined, officials turned to the U.S. 10th Circuit Court of Appeals, which turned them down on Christmas Eve.

The denial by the 10th Circuit panel -- which consisted of two appeals court judges, one appointed by President Obama and the other by President George W. Bush -- was notable because it hinted at skepticism of the state’s arguments.

To obtain a stay, the state had to show that it had a substantial likelihood of winning its eventual appeal and that allowing the marriages to continue in the meantime would cause “irreparable harm” to the state’s interests. The judges seemed unconvinced on both counts.

By contrast, when a federal judge struck down California’s Proposition 8, which banned same-sex marriages, the 9th Circuit blocked the ruling and kept the stay in effect until the Supreme Court ruled on the case last June.

Since Shelby’s ruling, hundreds of same-sex couples have wed in Utah -- weddings that in theory could be invalidated if the decision is eventually overturned. As of Monday evening, the Deseret News in Salt Lake City reported more than 700 marriage licenses had been issued to same-sex couples in the state. Many additional couples married Tuesday.

State officials may face an uphill battle in persuading the Supreme Court to step in at such an early stage. It’s common for the justices to put a ruling on hold once they’ve decided to review a case. But in this case, the state’s appeal hasn’t even been argued to the lower appellate court. The justices could simply decline Utah’s request to get involved and wait to see how the lower court handles the matter.

If that happens, same-sex marriages in Utah probably would continue for weeks or months. The appeals court panel that denied the stay Tuesday said the state’s appeal would be expedited. But even in a hurried-up status, an appeals court ruling might not come until early spring.

Lesson: Introduction to Same-Sex Marriage Rights in the United States

### Section 1: Theoretical Concepts

In this lesson, we will learn about the legal status of same-sex marriage in the United States, including the history of the issue, the role of the courts, and the current state of the law. We will also explore the arguments for and against same-sex marriage rights and consider the impact of these rights on society.

### Section 2: Questions and Answers

1. What is same-sex marriage?
Same-sex marriage is the practice of marriage between two people of the same sex, typically as a result of a governmental or religious recognition of their relationship.

2. When did same-sex marriage become legal in the United States?
Same-sex marriage became legal in the United States in 2015 when the Supreme Court ruled in Obergefell v. Hodges that the Constitution requires all states to license marriages between two people of the same sex and to recognize such marriages performed in other states.

3. How has the legal status of same-sex marriage changed over time?
The legal status of same-sex marriage has changed significantly over time. Until 2015, only a few states allowed same-sex marriage. However, after the Obergefell decision, all states were required to allow same-sex marriage.

4. Why is same-sex marriage controversial?
Same-sex marriage is controversial because some people believe that it goes against their religious beliefs or that it will harm traditional marriage. Others argue that same-sex marriage is a civil rights issue and that denying same-sex couples the right to marry is discriminatory.

### Section 3: Definitions and Examples

1. What is the definition of marriage?
Marriage is a legally recognized union between two people, typically for the purpose of creating a family. It can be defined differently in different cultures and religions.

2. What is the difference between civil marriage and religious marriage?
Civil marriage is a marriage recognized by the government, while religious marriage is a marriage performed in accordance with the rituals and laws of a particular religion.

3. Can same-sex couples get married in every state?
Yes, same-sex marriage is legal in all 50 states after the Supreme Court's ruling in Obergefell v. Hodges.

### Section 4: Practical Examples and Real-World Scenarios

1. How does the legalization of same-sex marriage affect families?
The legalization of same-sex marriage allows same-sex couples to enjoy the same rights and benefits as opposite-sex couples, such as the ability to adopt children, inherit property, and make medical decisions for their partners.

2. How does the legalization of same-sex marriage affect businesses?
The legalization of same-sex marriage means that businesses must treat same-sex couples the same as opposite-sex couples in areas such as employee benefits, customer service, and marketing.

3. How does the legalization of same-sex marriage affect society as a whole?
The legalization of same-sex marriage has had a significant impact on society, as it has led to greater acceptance of same-sex relationships and has changed the cultural landscape of the United States.

### Glossary

Lesson: How to Read Music Notations

Introduction:
Music notations are a way to represent musical sounds with symbols, numbers, and letters. They are used to describe the pitch, rhythm, and dynamics of a piece of music. In this lesson, we will learn how to read and understand music notations.

Section 1: Understanding the Basics

- Pitch: Pitch refers to the highness or lowness of a sound. In music, the pitch is represented by the letter names of the notes on the staff. These notes are A, B, C, D, E, and F.
- Rhythm: Rhythm refers to the pattern of beats in a piece of music. It is represented by a series of symbols called notes, which indicate when each beat should be played.
- Dynamics: Dynamics refer to the loudness or softness of a piece of music. They are represented by symbols such as forte (loud), piano (soft), and crescendo (getting louder).

Section 2: Reading Music Notations

- Notes: Notes are the basic building blocks of music. They are represented by symbols such as whole notes, half notes, quarter notes, and eighth notes. Each note represents a different duration of sound.
- Rest: A rest is a period of silence in music. It is represented by a symbol that looks like a note but has no note head.
- Ledger Lines: Ledger lines are used to represent notes that fall outside the staff. They are drawn above or below the staff to indicate the pitch of the note.
- Time Signature: The time signature indicates the meter or rhythmic pattern of a piece of music. It is represented by two numbers written on the staff, one above the other.
- Key Signature: The key signature indicates the pitches of the notes in a piece of music. It is represented by sharps or flats placed on the staff.

Section 3: Practice Exercises

1. Identify the notes, rests, and dynamics in the following music notation:

text: I am using the 520 with a USB 3.0 dock- I have used this successfully with a Kingston SSD V+ drive and achieve read/write speads around 180 MB/S. With the same setup I am getting 70 MB/s write and 180 MB/S read speeds with the 520 ssd- is this simply due to the uncompressed data and sandyforce controller or does something else not add up here?. Link Copied. How do you test the performance? I see on the page for product specification that they test with AS-SSD* benchmark to get the incompressible data performance and with Iometer with Queue Depth 32 to get the other one, I believe also ATTO uses compressible data. Other than this, I can only think of maybe, the SATA to USB connection, but if it is the same one you have tested with the other hard drive then it would rule that part out.

Lesson: Introduction to Solid State Drives (SSD)

## Section 1: Theoretical Concepts

An SSD is a non-volatile storage device that uses flash memory to store data. It is faster and more reliable than traditional hard disk drives (HDD) because it has no moving parts. SSDs are used in computers, smartphones, and other electronic devices to store data quickly and efficiently.

## Section 2: Practical Examples

Let's consider a computer with an HDD and an SSD. When we turn on the computer, the operating system and applications are loaded from the SSD, which takes just a few seconds. On the other hand, if we were to load the same operating system and applications from an HDD, it would take much longer - several minutes or even longer. This is because the SSD can read and write data much faster than an HDD.

## Section 3: Real-World Scenarios

Suppose we have a video editing software that requires quick access to large files. Using an SSD as the storage device for this software would greatly improve its performance, as the SSD can read and write data at high speeds. On the other hand, if we were to use an HDD, the software would be slow and unresponsive, as it would take longer to access the data stored on it.

## Glossary
- SSD: Solid State Drive
- HDD: Hard Disk Drive
- Flash Memory: A type of non-volatile memory that can store data even when power is turned off
- Non-Volatile: A type of memory that retains data even when power is turned off
- Operating System: A program that manages computer hardware and software resources and provides common services for computer programs
- Application: A program or group of programs designed for end users
- Performance: The ability of a system, component, or process to deliver results in a timely and efficient manner
- Throughput: The rate at which data is transferred between a system and its environment

## Conclusion

In conclusion, SSDs are faster and more reliable than HDDs because they use flash memory to store data. They are commonly used in computers, smartphones, and other electronic devices to store data quickly and efficiently. By using an SSD as the storage device for software that requires quick access to large files, we can greatly improve its performance. Understanding the concepts of SSDs and their practical applications can help us make informed decisions when purchasing storage devices and optimizing computer performance.


text: Looks like Apple is in fact using the Mobility version of the X1600 in the new iMacs. Bummer. Compare the actual shot of the guts of the iMac (thanks, kodawarisan!): to the ATI product shot of the X1600 Mobility: Same chip (looking at the components around the chip). For comparison, here's an ATI product shot of the desktop X1600 chip: I understand why they would use a Mobility chip with the iMac's space considerations, but I think it's a bit deceptive of Apple, as they specifically say "X1600 Mobility" in their specs for the MacBook Pro, but only say "X1600" in their iMac specs, which might lead one to believe the iMac uses a full desktop X1600.

Lesson: Comparing Technical Specifications

Introduction:
In this lesson, we will learn about technical specifications and how to compare them. We will use the example of comparing graphics cards to illustrate this concept.

Section 1: Theoretical Concepts
- Technical specifications are details about a product or service that describe its characteristics and capabilities.
- These specifications help customers make informed decisions about what they are buying.

Section 2: Questions and Answers
- Why do we need to compare technical specifications?
- To determine if a product or service meets our needs and expectations.

Section 3: Definitions of Purpose
- The purpose of technical specifications is to provide accurate and reliable information about a product or service.

Section 4: Practical Examples
- Let's say you are looking for a new laptop. You find two laptops with similar prices and features, but one has an Intel Core i7 processor while the other has an AMD Ryzen 7 processor.
- To determine which laptop is better for your needs, you would need to compare the technical specifications of these processors.
- For example, you could look at the clock speed, number of cores, and cache size of each processor to see which one is faster and more efficient.

Section 5: Real-World Scenarios
- Let's say you are looking for a new graphics card for your computer. You find two graphics cards with similar prices and features, but one has an NVIDIA GeForce RTX 2070 while the other has an AMD Radeon VII.
- To determine which graphics card is better for your needs, you would need to compare the technical specifications of these graphics cards.
- For example, you could look at the number of CUDA cores, memory size, and clock speed of each graphics card to see which one is faster and more efficient.

Section 6: Increasing Difficulty Level
- Let's say you are looking for a new gaming computer. You find two computers with similar prices and features, but one has an Intel Core i9 processor while the other has an AMD Ryzen 9 processor.
- To determine which computer is better for your gaming needs, you would need to compare the technical specifications of these processors.
- For example, you could look at the clock speed, number of cores, and cache size of each processor to see which one is faster and more efficient.
- You could also look at the graphics card, amount of RAM, and storage capacity of each computer to see which one is better suited for gaming.

Glossary:
- Technical Specifications: Details about a product or service that describe its characteristics and capabilities.
- Clock Speed: The speed at which a processor can perform instructions.
- Number of Cores: The number of processing units in a processor.
- Cache Size: The amount of memory used by a processor to store frequently accessed data.

Conclusion:
In this lesson, we learned about technical specifications and how to compare them. We learned that technical specifications are important because they help us make informed decisions about what we are buying. We also learned about the different aspects of technical specifications, such as clock speed, number of cores, cache size, and more. By understanding these concepts, we can make better decisions when purchasing products or services.

Is there a way to scan a directory to see how many files of certain type there is?

So if I have a directory like below is there a way to scan how many files with a specific code in its name. For example if I want the number of files that start with 17042020 which would be 6 from the directory below?
1704202001-01.csv
1704202001-02.csv
1704202002-01.csv
1704202002-02.csv
1704202003-01.csv
1704202003-02.csv

A:

you can use the pathlib module or just plain glob :
 from pathlib import Path
 folder = Path(dir_of_files)
 specific_files = list(folder.glob('1704202001-*.csv')
 #or : list(folder.rglob('1704202001-*.csv') ... this will recursively search thru every subfolder for files that match this

 print(specific_files)

Lesson: How to Count Files of a Specific Type in a Directory

Introduction:
In this lesson, we will learn how to count files of a specific type in a directory using Python. This skill is useful in various fields such as computer science, data analysis, and digital forensics. We will use the `pathlib` and `glob` modules to achieve this.

Section 1: Installing the Modules
Before we begin, we need to install the `pathlib` and `glob` modules. You can install them using the following command:
```
pip install pathlib glob
```

Section 2: Importing the Modules
Once you have installed the modules, you can import them into your Python environment. Here's an example:
```python
import pathlib
import glob
```

Section 3: Using the `pathlib` Module
The `pathlib` module provides an object-oriented way to manipulate file paths. To count files of a specific type in a directory using the `pathlib` module, you can follow these steps:
1. Create a `Path` object for the directory you want to scan.
2. Use the `glob()` method to create a list of file paths that match your criteria.
3. Count the number of files in the list.
Here's an example:
```python
import pathlib
import glob

# Create a Path object for the directory
folder = pathlib.Path('/path/to/directory')

# Create a list of file paths that match your criteria
specific_files = list(folder.glob('1704202001-*.csv'))

# Count the number of files in the list
print(len(specific_files))
```

Section 4: Using the `glob` Module
The `glob` module provides a way to search for files using patterns. To count files of a specific type in a directory using the `glob` module, you can follow these steps:
1. Create a string containing the pattern you want to search for.
2. Use the `glob.glob()` function to create a list of file paths that match your criteria.
3. Count the number of files in the list.
Here's an example:
```python
import glob

# Create a string containing the pattern you want to search for
pattern = '1704202001-*.csv'

# Use the glob.glob() function to create a list of file paths that match your criteria
specific_files = glob.glob(pattern)

# Count the number of files in the list
print(len(specific_files))
```

Section 5: Practical Examples
Let's apply what we have learned to the following scenario:
Scenario: You have a directory containing CSV files with timestamps in their names. You want to count how many files have a specific timestamp.
Solution:
```python
import pathlib
import glob

# Create a Path object for the directory
folder = pathlib.Path('/path/to/directory')

# Create a list of file paths that match your criteria
specific_files = list(folder.glob('*.csv'))

# Extract the timestamps from the file names
timestamps = [int(file.split('-')[2]) for file in specific_files]

# Count the number of files with a specific timestamp
count = sum([1 for stamp in timestamps if stamp == 1704202001])
print('Number of files with timestamp 1704202001:', count)
```

Conclusion:
In this lesson, we learned how to count files of a specific type in a directory using Python. We used the `pathlib` and `glob` modules to achieve this. We also applied this skill to a practical scenario involving CSV files with timestamps in their names.

text: So Unreal. by LA Vampires. Released: Nov 2010. Label: Not Not Fun. At first blush, So Unreal is simply a lo-fi reimagining of new wave. This impression deepens with repeated spins. The beats and synths echo wearily, as if they're crushed by the weight of their own nostalgia. Amanda Brown, who fronts Pocahaunted as well, sounds genuinely dazed and confused. Her voice floats through that echo but fails to find anything real to cling to. On "How Would U Know," she dismantles the very notion of self through a repeated perversion of the title: "You could be anyone. How would I know? How would I know? How would I know?"

USA TODAY

EXETER, N.H. -- Donald Trump, retail politician.

The New York billionaire, seeking to regain political momentum after a second-place finish in Iowa, pursued an unusually crowded schedule Thursday in pursuit of a recovery win in next week's New Hampshire primary.

"You're going to play such a big role," Trump told Granite State residents packed into the well of Exeter's old-style town hall, also noting that he still leads many polls.

During the event, Trump avoided repeating his claim Wednesday that the Iowa winner, Ted Cruz, "stole" Monday's caucuses by misleading voters — a claim that continued to draw ridicule from some of his rivals.

“I don’t think it ever helps after you lose an election to ask for a do-over," Chris Christie told Fox News. "The fact is elections are played, they’re no beanbags, they’re not easy."

Christie, Trump, and other Republicans continued to criss-cross New Hampshire in a race with a number of cross-currents. They include the battle between Trump and Cruz, as well as attacks by Christie and Jeb Bush on Marco Rubio, who carried momentum from his strong showing in Iowa.

Trump, whose preference has been for rally speeches in big arenas, also planned some of the person-to-person campaigning that has marked the New Hampshire primary for more than a half-century. His schedule Thursday included a meeting with New Hampshire business owners in Exeter, and participation in a shift change in the Manchester Police Department. He also has another town hall Thursday night in Portsmouth.

The billionaire took questions at the town hall in Exeter, including one from a woman who protested his harsh comments about illegal immigration. Many migrants "do work no one else wants to do," the woman said, drawing boos from the pro-Trump crowd.

In a reference to Democratic candidate Bernie Sanders, Trump said to the woman: "Who told you to be here, Bernie?"

In attacking Cruz for his tactics in Iowa, Trump noted that Cruz operatives spread false rumors that Ben Carson was pulling out of the race, and urged his supporters to back the Texan. The Trump campaign has also hit a Cruz mailer that gave voters false information about qualifying to caucus.

Cruz said he has apologized to Carson, but mocked Trump's complaints about sour grapes. "I don’t think the people are interested in temper tantrums," Cruz said of the billionaire on Thursday.

Rubio, hoping to build on his third-place finish in Iowa, also stumped the Granite State in the face of heavy criticism from rivals.

Bush, the former Florida governor who backed Rubio's political rise in that state, told NBC News that his former protege is "a gifted politician," but his life is built "around his own ambitions." Bush also had his own special event planned for Thursday night, featuring mother and former first lady Barbara Bush.

Christie, appearing on MSNBC's Morning Joe, continued to argue that Rubio has done nothing in the U.S. Senate, and to describe Rubio as a "bubble boy" who avoids answering tough questions. The New Jersey governor noted that a new Rubio endorser — former presidential candidate Rick Santorum — couldn't name a Rubio accomplishment.

"So it's time for the boy in the bubble to come out of the bubble and answer these questions and tell us things rather than just continue to give the same speech he's been giving for the last six years," the New Jersey governor said.

Rubio, campaigning on the theme that he represents a new generation of leadership, said opponents are attacking him because he is doing well.

“It’s sad that after finishing near the bottom in Iowa, Jeb Bush and Chris Christie are now doing everything possible to tear down Marco Rubio, the one conservative who can beat Hillary Clinton" said Rubio spokesman Jahan Wilcox.

Many of these claims will be aired Saturday night, when Republican candidates gather for their last debate before Tuesday's primary.

Lesson: Understanding Political Polling

Introduction:
Political polling is a process used to gather information about people's opinions, preferences, and behavior regarding politics. It is an essential tool for understanding public opinion, predicting election outcomes, and making informed decisions. In this lesson, we will explore the basics of political polling, its methods, and how to interpret the results.

Section 1: What is Political Polling?
Political polling is the process of collecting data from a sample of people to represent the opinions of a larger population. It is used to gauge public opinion on various political issues, candidate preferences, and voting intentions. Pollsters use different methods to collect data, including telephone surveys, online surveys, and in-person interviews.

Section 2: How does Political Polling work?
Pollsters use random sampling techniques to select a representative sample of the population. This sample size can range from a few hundred to thousands of people, depending on the size of the population being surveyed. The sample must be representative of the larger population in terms of age, gender, race, and other demographic factors.

Section 3: Types of Political Polling Questions
There are several types of questions that pollsters ask during a political poll. These include:

1. Horse Race Questions: These questions ask respondents who they would vote for if the election were held today.

2. Issue Questions: These questions ask respondents about their opinions on specific political issues, such as healthcare, immigration, or taxes.

3. Candidate Evaluation Questions: These questions ask respondents about their opinions of specific candidates, their leadership abilities, and their trustworthiness.

Section 4: Interpreting Political Polling Results
Political polling results are presented as percentages, with the total percentage of respondents answering each question added up to 100%. The margin of error represents the statistical uncertainty of the results and is usually reported as a percentage. A larger margin of error means that the results are less reliable.

Section 5: Critical Thinking
Political polling is an essential tool for understanding public opinion and predicting election outcomes. However, it is crucial to remember that polls are not infallible and can be subject to errors and biases. It is essential to evaluate the methodology used in the poll, the sample size, and the margin of error before drawing conclusions.

Glossary:
- Sample Size: The number of people interviewed in a political poll.
- Margin of Error: The statistical uncertainty of the poll results.
- Random Sampling: A technique used to select a representative sample of the population.
- Telephone Surveys: A method of collecting data through phone calls.
- Online Surveys: A method of collecting data through online questionnaires.
- In-Person Interviews: A method of collecting data through face-to-face interactions.

Conclusion:
Understanding political polling is essential for anyone interested in politics. By learning about the methods used, the types of questions asked, and how to interpret the results, we can better understand public opinion and make informed decisions. As with any form of data collection, it is essential to critically evaluate the results and consider the potential sources of error.

Lesson: The Importance of Nature Reserves

Introduction:
Nature reserves are essential for the preservation of wildlife and their habitats. They provide a safe haven for plants and animals to thrive without human interference. In this lesson, we will explore the importance of nature reserves, their role in society, and why they are necessary for our survival.

Section 1: What is a Nature Reserve?
A nature reserve is a designated area of land where the primary aim is to protect and conserve wildlife and their habitats. These areas are usually owned by governments, charities, or private organizations that work to preserve the natural environment.

Section 2: Why are Nature Reserves Important?
Nature reserves are important because they provide a safe haven for plants and animals to thrive without human interference. They also help to maintain the balance of ecosystems, which is crucial for the survival of many species. Without nature reserves, many plants and animals would become extinct due to habitat loss, pollution, and other human activities.

Section 3: The Role of Nature Reserves in Society
Nature reserves play an essential role in society by providing people with opportunities to enjoy and learn about the natural world. They also help to educate people about the importance of conservation and the need to protect our environment. Additionally, nature reserves contribute to scientific research, which helps us to understand more about the natural world and how to protect it.

Section 4: How do Nature Reserves Help Wildlife?
Nature reserves help wildlife by providing them with a safe place to live, breed, and grow. They also help to protect endangered species from extinction by preventing human activities that could harm them. For example, some nature reserves have successfully brought back endangered species such as the bald eagle and the black-footed ferret.

Section 5: Conclusion
In conclusion, nature reserves are essential for the preservation of wildlife and their habitats. They provide a safe haven for plants and animals to thrive without human interference, and they play an important role in society by educating people about the importance of conservation. We must continue to support nature reserves and work towards creating more of them to ensure the survival of many species.

Glossary:
- Nature Reserve: A designated area of land where the primary aim is to protect and conserve wildlife and their habitats.

Reciprocal changes in intracellular and extracellular magnesium in rat pancreatic acinar cells in response to different secretagogues.
This study employs the fluorescent bioprobe Mag-fura-2 to measure the mobilisation of magnesium (Mg2+) in rat pancreatic acinar cells at rest and during stimulation with either cholecystokinin-octapeptide (CCK-8; 10(-8) M), acetylcholine (ACh; 10(-5) M) or histamine (10(-4) M). In Mag-fura-2 loaded acini suspended in normal Krebs-Ringer-Hepes (KRH) solution containing (mMol/litre) NaCL, 130; KCI, 5; HEPES, 20; KH2PO4, 1.2; CaCl2, 1.0; MgSO4, 1.0; glucose, 10; minimum essential medium, 1.0 ml/Litre and pH 7.4, both CCK-8 and ACh evoked a transient rise in intracellular free Mg2+ concentration ([Mg2+]i) followed by a sustained and prolonged decrease. Addition of CCK-8 to acinar cell suspension previously stimulated with ACh resulted in little or no change in [Mg2+]i indicating that the two secretagogues are mobilising magnesium from the same intracellular pool. Histamine had no significant effect on [Mg2+]i or on the CCK-8 evoked response. When acini were challenged in the presence of the cell-impermeant form of Mag-fura-2 (the tetrapotassium salt) in a Ca(2+)-free KRH solution containing 1-mM EGTA, CCK-8 and ACh, stimulation resulted in a gradual release of magnesium reaching a maximum after 300-350 s following application of the secretagogues (magnesium efflux). Again histamine had no effect on magnesium release. Incubation of acinar cells in a nominally magnesium-free KRH solution had no effect on basal [Mg2+]o. When challenged with CCK-8, [Mg2+]i rose transiently, followed by a sustained decrease. In contrast, ACh stimulation resulted in a triphasic response comprising an initial rise followed by a decrease, superceded by a small rise in [Mg2+]i. Again histamine had no effect on [Mg2+]i in nominally magnesium-free solution. Addition of either ACh or CCK-8 to cells placed in KRH solution with no added Mg2+ caused a small efflux of magnesium, as measured in the presence of the tetrapotassium salt of Mag-fura-2 (cell-impermeant form). These results, employing two different forms of a fluorescent bioprobe for the measurement of magnesium, indicate that unlike histamine, CCK-8 and ACh can evoke marked changes in intracellular free magnesium concentration during the stimulus-secretion coupling process.

Lesson: Intracellular and Extracellular Magnesium Changes in Pancreatic Acinar Cells

Introduction:
Magnesium is an essential mineral that plays a crucial role in various cellular processes. In this lesson, we will learn about the reciprocal changes in intracellular and extracellular magnesium in rat pancreatic acinar cells in response to different secretagogues.

Section 1: Understanding Intracellular and Extracellular Magnesium Changes

Topic 1: What are secretagogues?
Answer: Secretagogues are substances that stimulate the release of secretions from cells. In this case, they are used to stimulate the release of magnesium from rat pancreatic acinar cells.

Topic 2: What is Mag-fura-2?
Answer: Mag-fura-2 is a fluorescent bioprobe that is used to measure the mobilization of magnesium (Mg2+) in rat pancreatic acinar cells.

Topic 3: What is the role of magnesium in cellular processes?
Answer: Magnesium plays a crucial role in various cellular processes such as energy production, DNA synthesis, and cell signaling. It is also involved in the regulation of ion channels and neurotransmitter release.

Section 2: Measuring Intracellular and Extracellular Magnesium Changes

Topic 1: How is the mobilization of magnesium measured in rat pancreatic acinar cells?
Answer: The mobilization of magnesium in rat pancreatic acinar cells is measured using the fluorescent bioprobe Mag-fura-2. This probe binds to magnesium ions and emits a fluorescent signal that can be detected and measured.

Topic 2: What are the effects of different secretagogues on intracellular magnesium levels?
Answer: Different secretagogues have different effects on intracellular magnesium levels. Cholecystokinin-octapeptide (CCK-8) and acetylcholine (ACh) both evoke a transient rise in intracellular free magnesium concentration ([Mg2+]i) followed by a sustained and prolonged decrease. Histamine, on the other hand, has no significant effect on [Mg2+]i or on the CCK-8 evoked response.

Section 3: Applying Knowledge to New Problems

Topic 1: How can we apply our knowledge of magnesium mobilization in rat pancreatic acinar cells to other cell types?
Answer: Our understanding of magnesium mobilization in rat pancreatic acinar cells can be applied to other cell types by studying their response to secretagogues and measuring intracellular magnesium levels using appropriate bioprobes.

Topic 2: How can we use our knowledge of magnesium mobilization to develop new therapeutic strategies?
Answer: Our understanding of magnesium mobilization can be used to develop new therapeutic strategies by targeting the intracellular magnesium levels in various cell types. For example, drugs that increase intracellular magnesium levels could be used to treat conditions such as hypomagnesemia or magnesium deficiency.

Conclusion:
In this lesson, we have learned about the reciprocal changes in intracellular and extracellular magnesium in rat pancreatic acinar cells in response to different secretagogues. We have also discussed the importance of magnesium in cellular processes and the methods used to measure its mobilization. Finally, we have explored how our knowledge of magnesium mobilization can be applied to other cell types and used to develop new therapeutic strategies.

Lesson: Introduction to Power Supplies

## Section 1: Theoretical Concepts
Power supplies are essential components in electronic systems that provide electric energy to the circuits. They convert the AC power from the wall outlet into DC power that can be used by the circuits. There are different types of power supplies, such as linear, switching, and intermediate bus. In this lesson, we will focus on switching power supplies, which are the most common type used in electronic systems.

Switching power supplies use a switching regulator to convert the input voltage to a fixed output voltage. The regulator compares the output voltage to a reference voltage and turns the output transistor on and off to maintain the desired output voltage. The frequency at which the output transistor turns on and off is called the switching frequency. The higher the switching frequency, the smaller the output filter capacitors can be, which reduces the size and cost of the power supply.

## Section 2: Practical Examples
Let's consider a simple example of a switching power supply that converts an input voltage of 12V to an output voltage of 5V. The input voltage is connected to the input of the regulator, and the output voltage is connected to the output. The regulator compares the output voltage to the reference voltage (which is typically 1.2V for a 5V output) and turns the output transistor on and off to maintain the desired output voltage.

The efficiency of a power supply is the ratio of the output power to the input power. A higher efficiency means that more of the input power is converted into useful output power, which reduces the heat generated by the power supply and increases its lifetime. The efficiency of a switching power supply depends on several factors, including the switching frequency, the output load, and the input voltage.

## Section 3: Real-World Scenarios
Switching power supplies are used in many electronic devices, such as computers, smartphones, and tablets. They are also used in industrial applications, such as motor drives and power tools. In these applications, the power supply must be able to handle a wide range of input voltages and output currents while maintaining a high efficiency.

## Glossary
- Input voltage: The voltage supplied by the power source to the power supply.
- Output voltage: The voltage provided by the power supply to the circuit.
- Reference voltage: The voltage compared to the output voltage by the regulator.
- Switching frequency: The frequency at which the output transistor turns on and off in a switching power supply.
- Efficiency: The ratio of the output power to the input power.
- Input current: The current supplied by the power source to the power supply.
- Output current: The current provided by the power supply to the circuit.

## Conclusion
In this lesson, we learned about switching power supplies, their theoretical concepts, and practical examples. We also explored real-world scenarios where switching power supplies are used. By understanding these concepts, we can design and select the appropriate power supply for our electronic systems.

Lesson: Introduction to Photography

### Section 1: Theoretical Concepts
Photography is the art of capturing light and turning it into an image. It involves using a camera to record the scene in front of you and preserve it for future viewing. In this lesson, we will explore the basics of photography, including composition, exposure, and focus.

### Section 2: Practical Examples
To understand photography, it is essential to know how to use a camera. A camera is made up of several parts that work together to create an image. The aperture is the opening in the lens that controls the amount of light that enters the camera. The shutter speed is the length of time that the camera's sensor is exposed to light. The ISO setting determines how sensitive the camera's sensor is to light. By adjusting these settings, you can control the amount of light that enters the camera and create the perfect exposure for your shot.

### Section 3: Real-World Scenarios
Now that you understand the basics of photography, let's put them into practice. Let's say you are taking a picture of a landscape. You want to make sure that the foreground, middle ground, and background are all in focus. To do this, you would use a small aperture (large f-stop number) to ensure that everything in the frame is in focus. You may also want to use a tripod to keep the camera steady and avoid blurry images due to camera shake.

### Glossary
- Aperture: The opening in the lens that controls the amount of light that enters the camera.
- Shutter Speed: The length of time that the camera's sensor is exposed to light.
- ISO: The sensitivity of the camera's sensor to light.
- Composition: The arrangement of elements in a photograph.
- Exposure: The amount of light that enters the camera.
- Focus: The sharpness of the image.

### Conclusion
In this lesson, we learned the basics of photography, including composition, exposure, and focus. We also explored practical examples and real-world scenarios to put these concepts into practice. By understanding these principles, you can take stunning photographs that capture the beauty of the world around you.
