Lesson Title: Understanding the Benefits of Underwater Treadmills

Introduction:
Underwater treadmills are a type of exercise equipment that allows individuals to walk or run while submerged in water. This unique form of exercise has numerous benefits for individuals with a variety of physical conditions. In this lesson, we will explore the benefits of underwater treadmills and how they can help improve overall health and wellness.

Section 1: Understanding the Benefits of Underwater Treadmills

Topic 1: Pain Relief
One of the most significant benefits of underwater treadmills is their ability to provide relief from pain associated with various physical conditions. When exercising in water, the body experiences less resistance, which can reduce the amount of pain experienced during exercise. This makes it an excellent option for individuals with arthritis, joint disorders, and other conditions that cause pain during physical activity.

Topic 2: Improved Mobility
Another significant benefit of underwater treadmills is their ability to improve mobility. The resistance provided by the water helps to strengthen muscles and improve overall flexibility. This can be particularly beneficial for individuals who have been injured or have limited mobility due to a physical condition.

Topic 3: Increased Strength and Endurance
Underwater treadmills also provide an excellent opportunity to increase strength and endurance. The water provides resistance, which can help build muscle mass and improve cardiovascular health. This can be particularly beneficial for individuals who are recovering from an injury or have limited mobility.

Section 2: Practical Examples and Real-World Scenarios

Example 1: A person with arthritis may find that walking on an underwater treadmill reduces their pain and allows them to exercise more comfortably than they could on land.

Example 2: An individual recovering from a lower-extremity injury may use an underwater treadmill to improve their mobility and build strength in their legs.

Example 3: A professional athlete may use an underwater treadmill to improve their cardiovascular endurance and build muscle mass.

Section 3: Self-Debating Discussions

Question: How does an underwater treadmill differ from a traditional treadmill?
Answer: An underwater treadmill is submerged in water, which provides resistance and reduces pain during exercise. Traditional treadmills do not have this benefit and can cause increased pain for individuals with certain physical conditions.

Question: Is an underwater treadmill appropriate for everyone?
Answer: While underwater treadmills have many benefits, they may not be appropriate for everyone. Individuals with certain medical conditions or those who are prone to aquaphobia (fear of water) may not be good candidates for this type of exercise equipment.

Conclusion:
In conclusion, underwater treadmills offer numerous benefits for individuals with a variety of physical conditions. By providing pain relief, improving mobility, and increasing strength and endurance, these exercise machines can help individuals achieve better overall health and wellness.

Determinants of cadmium burden levels in a population of children living in the vicinity of nonferrous smelters.
This report covers part of the assessment of a site in northern France polluted by industrial metal emissions. Our objectives were to assess the cadmium burden in children aged 8 to 11 years and look for factors that affected it. A cross-sectional population-based study took place in 1996-1997 and included 400 children (200 in the metal-polluted area). The geometric mean of the blood cadmium (CdB) levels of children living on the polluted site was 0.51 microg/L (95% CI=[0.49-0.53]); that of the nonexposed children was 0.47 microg/L (95% CI=[0.45-0.49]) (P<0.01). The geometric mean of the urinary cadmium (CdU) levels of children living on the polluted site was 1.16 microg/g creatinine (95% CI=[1.01-1.34]); that of the nonexposed children was 0.99 microg/g creatinine (95% CI=[0.86-1.14]) (P=0.10). Mean CdB was higher among children within 4 km of a zinc smelter and consuming > or =500 ml of tap water daily (x1.34; 95% CI=[1.14-1.51]) compared with children living more than 4 km away and consuming <500 ml of tap water daily. Independently of this association, consumption of fish and shellfish (> or =once a week vs. <once a week) and homegrown vegetables (> or =once daily vs. <once daily) was associated with higher mean CdB levels, respectively: x 1.14; 95% CI=[1.07-1.21] and x 1.25; 95% CI=[1.04-1.50]. Neither sex nor age was associated with CdB. Mean CdU was associated with paternal occupational cadmium exposure.

Cadmium is a toxic heavy metal that can cause serious health problems, including kidney damage and bone disease. Children are particularly vulnerable to the effects of cadmium because their bodies are still developing. In this study, we looked at the levels of cadmium in the blood and urine of children living near a nonferrous smelter in northern France. We found that children living closer to the smelter and consuming more tap water had higher levels of cadmium in their bodies. This suggests that exposure to cadmium from industrial emissions can have a significant impact on the health of children living in the vicinity of these facilities.

**Lesson:**

**Introduction:**

In this lesson, we will learn about the determinants of cadmium burden levels in children living near nonferrous smelters. We will explore the factors that affect cadmium levels in the blood and urine of children and discuss the potential health risks associated with exposure to this toxic heavy metal.

**Section 1: What is Cadmium?**

Cadmium is a toxic heavy metal that is commonly found in the environment due to human activities such as mining, smelting, and manufacturing. It can be absorbed into the body through inhalation, ingestion, and skin contact. Cadmium can accumulate in the body over time and has been linked to a variety of health problems, including kidney damage, bone disease, and an increased risk of lung cancer.

**Section 2: Determinants of Cadmium Burden Levels**

In this study, we looked at two main determinants of cadmium burden levels in children living near a nonferrous smelter in northern France: distance from the smelter and consumption of tap water. We found that children living closer to the smelter and consuming more tap water had higher levels of cadmium in their blood and urine.

**Section 3: Health Risks Associated with Cadmium Exposure**

Exposure to high levels of cadmium can have serious health consequences. Kidney damage is one of the most common effects of cadmium poisoning, and long-term exposure can lead to chronic kidney disease. Cadmium can also interfere with bone formation and remodeling, leading to osteoporosis and an increased risk of fractures. Additionally, exposure to cadmium has been linked to an increased risk of lung cancer.

**Section 4: Conclusion**

In conclusion, this study demonstrates that exposure to cadmium from industrial emissions can have a significant impact on the health of children living in the vicinity of nonferrous smelters. Understanding the determinants of cadmium burden levels in these populations is essential for developing strategies to reduce exposure and protect public health.

Organophosphorus pesticide poisoning: cases and developments.
Self-poisoning with organophosphate pesticides is a major health problem world-wide. Through the inhibition of acetylcholinesterase, organophosphorus poisoning is characterised by the clinical picture of acute cholinergic crisis. Other manifestations are the intermediate neurotoxic syndrome and delayed polyneuropathy. In the Western world, the occurrence of organophosphorus poisoning is less prevalent due to the declining availability of organophosphate pesticides, which could render the recognition of this particular type of intoxication and its specific treatment more difficult. In this article we discuss some recent developments and treatment dilemmas, illustrated by cases from our clinic, followed by a review of the current recommendations in the treatment of organophosphate poisoning.

textbook:
Lesson: Organophosphorus Poisoning - Causes, Symptoms, and Treatment

Introduction:
Organophosphorus pesticides are a group of chemicals used to control pests in agriculture. They work by inhibiting the enzyme acetylcholinesterase, which is responsible for breaking down a neurotransmitter called acetylcholine. When acetylcholine accumulates in the body, it can cause a range of symptoms, including muscle twitching, weakness, and respiratory distress. In this lesson, we will learn about the causes, symptoms, and treatment of organophosphorus poisoning.

Causes:
Organophosphorus poisoning occurs when someone is exposed to organophosphorus pesticides. This can happen through ingestion, inhalation, or skin contact. The most common cause of organophosphorus poisoning is intentional or accidental ingestion of these pesticides. This can occur when someone swallows a pesticide or when they eat food that has been contaminated with the pesticide.

Symptoms:
The symptoms of organophosphorus poisoning can vary depending on the amount of pesticide that was ingested and the individual's overall health. Some common symptoms include:
- Muscle twitching or weakness
- Difficulty breathing or shortness of breath
- Nausea and vomiting
- Salivation or excessive sweating
- Runny nose and tearing eyes
- Confusion and disorientation
- Seizures
- Coma and death

Treatment:
The treatment for organophosphorus poisoning depends on the severity of the symptoms and the amount of pesticide that was ingested. In mild cases, supportive care may be all that is needed. This can include providing fluids and electrolytes, monitoring vital signs, and treating any symptoms as they arise. In more severe cases, a medication called atropine may be administered. Atropine works by blocking the effects of acetylcholine, which can help to relieve some of the symptoms of poisoning. In some cases, other medications may also be used to help manage the symptoms.

Conclusion:
Organophosphorus poisoning is a serious health problem that can occur when someone is exposed to organophosphorus pesticides. The symptoms of poisoning can range from mild to severe, and the treatment depends on the individual's overall health and the amount of pesticide that was ingested. By understanding the causes, symptoms, and treatment of organophosphorus poisoning, we can better prepare ourselves for potential exposures and ensure that those who are affected receive the appropriate care.

Lesson: Understanding Weather Forecasts

## Introduction

Weather forecasts are an essential part of our daily lives, especially during holidays like the Bank Holiday weekend. In this lesson, we will learn how to understand and interpret weather forecasts by analyzing the one given above.

## Section 1: Understanding Weather Forecasts

### Subsection 1.1: What is a weather forecast?

A weather forecast is a prediction of the weather conditions that will occur in a particular area over a certain period of time. Meteorologists use scientific principles and advanced computer models to make these predictions.

### Subsection 1.2: How do meteorologists make weather forecasts?

Meteorologists use data from weather stations, satellites, radar, and other sources to gather information about the current weather conditions. They then use this information, along with their knowledge of atmospheric science, to create mathematical models that predict how the weather will change over time. These models take into account many factors, such as temperature, humidity, wind, and precipitation.

### Subsection 1.3: Why are weather forecasts important?

Weather forecasts are important because they help us plan our daily activities and prepare for severe weather conditions. For example, if a weather forecast predicts heavy rain, we can bring an umbrella or stay indoors to avoid getting wet. If a forecast predicts a heat wave, we can take precautions to stay cool and hydrated.

## Section 2: Analyzing the Weather Forecast

### Subsection 2.1: Reading the Weather Forecast

The weather forecast for the Bank Holiday weekend is given in the following text:

"The Bank Holiday weekend is looking to be very changeable – with no two days the same! On Saturday, today’s rain will drift into northern England. Ahead of the rain, most of Scotland and Northern Ireland will be much cooler with slow-moving showers, sometimes heavy. Most of England and Wales will be plagued by hefty showers, with some prolonged and thundery downpours. Southern counties will become increasingly windy, with strong gusts along Channel coasts. Sunday is looking to be the best day of the long weekend. It’ll be drier for the majority with a chance of brighter skies and the winds across the south will ease leaving a calmer day. On Monday, things deteriorate again as another batch of windy, wet weather sweeps in from the west. Temperatures will be a little on the low side for the time of year too."

### Subsection 2.2: Analyzing the Weather Forecast

From the given weather forecast, we can see that the weekend is going to be changeable, with no two days being the same. On Saturday, there will be rain in northern England, and before that, Scotland and Northern Ireland will experience slow-moving showers, sometimes heavy. Most of England and Wales will have hefty showers, with some prolonged and thundery downpours. The southern counties will also become increasingly windy, with strong gusts along the Channel coasts.

On Sunday, the weather is expected to improve, with it being drier for the majority, and a chance of brighter skies. The winds across the south will ease, leaving a calmer day. However, on Monday, things will deteriorate again as another batch of windy, wet weather sweeps in from the west.

Overall, the weather forecast suggests that the Bank Holiday weekend will be characterized by changeable weather conditions, with no two days being the same.

## Section 3: Applying Weather Forecasts in Real Life

### Subsection 3.1: Using Weather Forecasts to Plan Activities

Weather forecasts can help us plan our activities for the day or the weekend. For example, if we know that it will rain on Saturday, we can plan indoor activities or cancel outdoor plans. Similarly, if we know that Sunday will be sunny and calm, we can plan picnics or outdoor sports.

### Subsection 3.2: Using Weather Forecasts to Stay Safe

Weather forecasts can also help us stay safe during severe weather conditions. For example, if a forecast predicts a heat wave, we can take precautions to stay cool and hydrated. If a forecast predicts a hurricane, we can evacuate the area or take shelter in a safe location.

## Glossary

- Weather: The state of the atmosphere in a particular area, including temperature, humidity, wind, and precipitation.
- Meteorologist: A scientist who studies the weather and makes weather forecasts.
- Atmospheric science: The study of the Earth's atmosphere, including its composition, behavior, and interactions with other systems.

Q:

Using Carbon Copy Cloner 4 to create encrypted bootable HFS+ clones from APFS source

Background
According to the Carbon Copy Cloner documentation CCC4 cannot clone the Recovery HD from an APFS source to an HFS+ target:

Note: CCC v4 requires an HFS+ formatted source for creating Recovery HD volumes on HFS+ formatted destination volumes. If your source volume is formatted APFS, CCC v4 will not be able to create (or update) a recovery volume on the destination. CCC v5 adds support for APFS recovery volumes.

According to other CCC documentation, spinning platter target disks should be formatted as HFS+:

Starting in macOS High Sierra, both APFS and Mac OS Extended (Journaled) are acceptable formats for a backup of macOS 10.13. Mirroring Apple's recommendations, we recommend that you choose APFS if your destination device is a Flash storage-based device (e.g. an SSD) and will be used to back up 10.13 or higher. Choose Mac OS Extended (Journaled) if your destination device is a spinning-platter-based device (i.e. a hard disk drive, or HDD), or if you are backing up an operating system older than 10.13.

Anyone who's upgraded to High Sierra with an SSD internal disk knows that your startup disk was automatically updated from HFS+ to AFPS as part of that upgrade.
A Recovery HD on an external clone might not seem like that big of a deal: you could use a bootable USB thumb drive, or maybe Internet Recovery, if needed. However, FileVault requires a Recovery HD in order to encrypt the volume, according to Apple's support documentation:

Without a Recovery System, FileVault won't encrypt your startup drive.
  https://support.apple.com/en-us/HT204837
You don't need a recovery system to install and use macOS, but without it you can't use FileVault, set up a firmware password, or use Disk Utility to repair the disk.
  https://support.apple.com/en-us/HT201316

The Question
Given all of this, how can I create a bootable, encrypted clone of my APFS High Sierra source drive using Carbon Copy Cloner 4 (CCC4) and using external HFS+ disks?

A:

Here's what worked

Download the High Sierra installer from the App Store.
Run the installer, choosing the external clone disk as the target. This will automatically create a new Recovery HD partition associated with the target disk.
Reboot from the external disk. Hold down option key during startup to select the boot disk.
Enable FileVault encryption as usual from the Security & Privacy panel in System Preferences.

Additional Notes

You can reboot from your internal drive for better performance, after enabling FileVault on the external. The encryption task will continue as long as you're plugged into power and the external disk is connected.
It may take several hours, or even days, before encryption is done, depending on the volume of data to be encrypted.
You can view encryption task progress using the Terminal command diskutil cs list

What didn't work
There are some articles posted about how to clone the internal disk Recovery HD volume to any other drive, but I didn't have success with them:
$ diskutil list

text: June 9, 2010 brought immense rains and flooding to Landa Park. The grounds of the park were devastated and structures, including the wading pool bridge, were damaged. Volunteers and staff quickly got to work removing debris and the park was re-opened within one week.. During the cleanup, a donation of $10,000 was made to the New Braunfels Parks Foundation by NewQuest Properties to help with repairs to the park. The Parks Foundation voted to use this money to pay for handrails on the Wading Pool Bridge which was removed due to structural damage.. The new handrails, made by a local artist, are reminiscent of the cedar railings that were common in Landa Park in the early 1900's. The new rails are structurally significant and able to withstand high water.

Lesson: Introduction to Browsers and Their Support

## Section 1: Theoretical Concepts
A web browser is a software application used to access and interact with websites and online services on the internet. It interprets and displays HTML, CSS, and other web technologies to create a user-friendly experience. Different browsers may display web pages differently due to differences in their rendering engines, which interpret the code.

## Section 2: Practical Examples
Onfido's Dashboard is a web-based platform that allows users to manage their identity verification services. To access the Dashboard, users must use a supported browser. For example, if a user tries to access the Dashboard using an unsupported version of Internet Explorer, they may encounter errors or a degraded experience.

## Section 3: Self-Debating Discussions
Why is it important for users to use supported browsers when accessing the Dashboard?

Argument 1: Using a supported browser ensures that the Dashboard will function correctly and provide a seamless experience for the user. This is because supported browsers have been tested and optimized for the Dashboard, while unsupported browsers may not display the Dashboard correctly or may cause errors.

Argument 2: Supporting only modern browser versions helps ensure that the Dashboard is secure and up-to-date with the latest web technologies. Older browser versions may not have the latest security features or may be vulnerable to hacking attempts.

## Glossary

Lesson: Inventing and Entrepreneurship

Introduction:
Invention and entrepreneurship are two important aspects of our society. Inventors come up with new ideas and products that make our lives easier and more convenient. Entrepreneurs take these ideas and turn them into successful businesses. In this lesson, we will explore the process of invention and entrepreneurship, and learn about some of the challenges and rewards that come with starting your own business.

Section 1: The Process of Invention
The process of invention begins with an idea. This idea can come from anywhere - a conversation with a friend, a news article, or even a dream. Once you have an idea, the next step is to research and develop it. This involves creating prototypes, testing them, and making changes until you have a product that works well and meets the needs of your target market.

Questions and Answers:

It also involves taking risks and being willing to fail, because not every business venture will be successful.

Questions and Answers:
- What is entrepreneurship?
- Answer: Entrepreneurship is the process of turning an idea into a successful business.

Section 3: Challenges and Rewards
Starting your own business can be challenging, but it can also be incredibly rewarding. Some of the challenges you may face include competition from other businesses, financial difficulties, and the need to constantly adapt and innovate to stay ahead of the curve. However, the rewards of entrepreneurship can be significant, including the satisfaction of creating something from nothing, the potential for financial success, and the ability to make a positive impact on the world.

Questions and Answers:
- What are some of the challenges of entrepreneurship?
- Answer: Some of the challenges of entrepreneurship include competition from other businesses, financial difficulties, and the need to constantly adapt and innovate.

Q:

Migrate from SharePoint 2010 to 2013 with version control

Good morning everyone.
I have a local server with a SharePoint Foundation 2010 site that contains a documents library with version control and own metadata (ie, new columns containing information).
I need to migrate this SharePoint 2010 to SharePoint Online (which is 2013 version) or an Office 365 license with SharePoint 2013.
Is it possible to perform this migration while retaining the specified library with all versions of documents and values of their new metadata?
If it's not possible direct migration, would it be possible to migrate local SharePoint 2010 to 2013 and then migrate the local server to on-line keeping the library as in the previous case?
Thank you very much in advance for your comments.

A:

I think your requirement can be met by a tool called ShareGate. You can use trial version to finish the migration.

Lesson: Migrate from SharePoint 2010 to 2013 with version control

## Chapter 1: Introduction

### Section 1.1: What is SharePoint and why migrate?

SharePoint is a web-based platform developed by Microsoft, used for building intranet websites and document management systems. It allows users to create, share, and collaborate on documents, spreadsheets, and presentations.

There are several reasons why you might want to migrate from SharePoint 2010 to 2013, including:

- Access to new features: SharePoint 2013 introduced many new features, such as social networking integration, improved search capabilities, and better support for mobile devices.
- Improved performance: SharePoint 2013 has been optimized for better performance, with faster load times and improved scalability.
- Compatibility with newer technologies: SharePoint 2013 is compatible with newer technologies like Office 365, which provides additional benefits like cloud storage and automatic updates.

### Section 1.2: How to migrate from SharePoint 2010 to 2013

There are several ways to migrate from SharePoint 2010 to 2013, but one of the most common methods is to use a third-party tool like ShareGate. ShareGate is a powerful tool that allows you to migrate your SharePoint sites, lists, libraries, and items to a new SharePoint environment.

Here are the steps to follow when using ShareGate:

1. Install ShareGate on your computer and connect to your source SharePoint 2010 environment.
2. Configure the settings for your target SharePoint 2013 environment, such as the URL, username, and password.
3. Select the sites, lists, and libraries you want to migrate, and choose whether you want to migrate the content only or the content and settings.
4. Preview the migration to ensure that everything looks correct, and then run the migration.
5. Verify that the migration was successful and that all your content and settings have been transferred correctly.

## Chapter 2: Technical Details

### Section 2.1: Understanding the migration process

The migration process involves several steps, including:

1. Connecting to the source SharePoint 2010 environment
2. Connecting to the target SharePoint 2013 environment
3. Selecting the sites, lists, and libraries to migrate
4. Previewing the migration
5. Running the migration
6. Verifying the success of the migration

During the migration process, ShareGate creates a temporary database containing all the data from the source SharePoint 2010 environment. It then uses this database to migrate the selected content to the target SharePoint 2013 environment.

### Section 2.2: Understanding the technical challenges

One of the main technical challenges when migrating from SharePoint 2010 to 2013 is ensuring that all the content and settings are transferred correctly. This includes:

- Metadata: Make sure that all the custom metadata associated with your documents is migrated correctly.
- Permissions: Ensure that the correct permissions are set on the migrated content to match those of the original content.
- Version control: If your source SharePoint 2010 library had version control enabled, make sure that the migrated library also has version control enabled and that all versions of the documents are retained.

Another challenge is dealing with any compatibility issues that may arise between the two versions of SharePoint. For example, some custom code or applications that were developed for SharePoint 2010 may not work correctly on SharePoint 2013.

## Chapter 3: Practical Examples

### Section 3.1: Migrating a documents library with version control

Let's say you have a documents library on your SharePoint 2010 site that contains thousands of files, many of which have multiple versions due to version control. You want to migrate this library to a new SharePoint 2013 environment while retaining all the versions of the documents and the values of their new metadata.

Using ShareGate, you can select the documents library and choose to migrate both the content and settings. During the migration process, ShareGate will create a temporary database containing all the data from the source SharePoint 2010 environment. It will then use this database to migrate the selected content to the target SharePoint 2013 environment, including all the versions of the documents and the values of their new metadata.

After the migration is complete, you can verify that all the content and settings have been transferred correctly by checking the properties of the migrated documents and comparing them to the original content.

### Section 3.2: Migrating a site collection with custom code

Let's say you have a site collection on your SharePoint 2010 environment that contains several sites, each with custom code and applications developed specifically for that environment. You want to migrate this site collection to a new SharePoint 2013 environment while retaining all the custom code and applications.

Using ShareGate, you can select the site collection and choose to migrate both the content and settings. During the migration process, ShareGate will create a temporary database containing all the data from the source SharePoint 2010 environment. It will then use this database to migrate the selected content to the target SharePoint 2013 environment, including all the custom code and applications.

After the migration is complete, you can verify that all the content and settings have been transferred correctly by testing the custom code and applications on the migrated site collection.

## Chapter 4: Glossary

- SharePoint: A web-based platform developed by Microsoft, used for building intranet websites and document management systems.
- Migration: The process of moving data from one environment to another.
- ShareGate: A third-party tool used to migrate SharePoint sites, lists, libraries, and items to a new SharePoint environment.
- Metadata: Data about data, such as author, date created, or file type.
- Version control: A system that tracks changes to a document or set of documents, allowing users to revert to previous versions if necessary.

Today we got back sort of late from a fun weekend of camping, but it was still nice and sunny out, so I decided to quickly knock out the inspection to get it taken care of. But as a result, there aren’t all that many pictures this time.

BUT – I totally forgot to mention in last week’s inspection report that I tried yet another smoker fuel: Wood Pellets. The same stuff you burn in pellet stoves for heating purposes:

Unfortunately, I am not completely sold on them, either. They do produce smoke:

And the smell isn’t unpleasant either, but

they are difficult to get started

they burn HOT, even inside the mostly enclosed smoker

the hotter they burn, the less smoke you get

mostly burnt-up pellets tend to fall out of the hole where the bellows blows air into the smoker, and create a fire hazard on a super dry lawn.

I am still having the best results with a cedar kindling fire and ripped cotton fabric on top. The trick is to get it going really well, so the fire doesn’t completely go out, and just keeps on smoldering. I may experiment with mixing in some pellets as fuel, but not as the main source of smoke generation.

This is the inner cover of West-Hive.

The bees have tried to attach it to the frames again. There was a lot more burr comb this time than I had seen in several weeks (burr comb is wax comb that the bees build where you don’t want them to – extending beyond the boundaries of the frames, making them hard to manipulate, or on top / in between frames, connecting them).

You can see a little bit of burr comb on the lower left side in this picture – I didn’t fully get all of it in the shot.

Nice progress on a frame out of the top hive body of West Hive.

This is a lot of capped brood on a frame out of West Hive’s upper hive body. There were about 6 fully drawn out frames in the upper hive body, with 3 frames largely untouched. If the bees keep it up, I may be able to put up the first honey super next weekend!

Another fully loaded brood frame from West Hive.

Big chunks of burr comb on a frame from the upper hive body of East Hive. I removed it all using the sharp edge of the hive tool.

As I was looking at one of the frames of East Hive, something caught my eye. If you look toward the right side of the picture, about 2/3 down, you can see a new bee in the process of hatching! Her head is barely sticking out of her cell.

No Queen sightings in either hive, but lots of fresh eggs, in nice tight patterns. That means the Queens were there at least of a few days ago, and seem to be generally healthy.

observation I made is that the bees have started producing a lot of propolis, a resinous “bee glue”. They make it by collecting sap mostly from tress. It’s orange-brown in color, SUPER sticky, and will stain most any surface – including skin! The bees use it to fill gaps in the hive, and to improve the structural integrity by gluing components together.

In a movable frame environment, propolis is your enemy. It’s best to scrape it off the frames wherever you see it, because the longer you let it go, the stronger the bond becomes, and you may have a hard time separating the frames.It appears that East Hive is using it A LOT more than West Hive. Almost all the frames in the lower hive body of East Hive showed signs of it, whereas West Hive barely had any.

There supposedly are medicinal uses for propolis, so I have been collecting whatever I scrape off the frames. It’ll take a while to have any significant quantities though, so stay tuned.

Both hives had fully consumed all their sugar syrup – the Honey-B-Well must have been doing its thing. I had run out of syrup refill, so I had to make more after the inspection – it has to fully cool down before you can use it, so I will have to add the feeding pails back onto the hives tomorrow

When I first started backyard beekeeping as a hobby, I blogged about it at http://www.crownhillbees.com. I recently read over the old site again, and decided that rather than letting it linger out there in abandoned blog never-never-land, I would import the posts and host them here on the DanTheBeeMan blog. I hope you enjoy reading […]

The bees have been very busy, and their population numbers have practically exploded. Both hives are each occupying about 75% of their total hive space now. I think this coming weekend, it’s time to put on the first honey super. Honey supers are less deep (or more shallow) than the hive bodies. That’s because once […]

Lesson: How to Start a Fire Safely and Efficiently

Introduction:
Fire is an essential tool for human beings. It provides warmth, light, cooks food, and purifies water. However, starting a fire safely and efficiently requires knowledge and skill. In this lesson, we will learn about different methods of starting a fire, the importance of tinder, kindling, and fuel, and how to maintain a fire safely.

Section 1: Types of Fire Starters
There are several methods of starting a fire, including matches, lighters, flint and steel, and magnesium fires. Each method has its advantages and disadvantages.

Matches are convenient and easy to use, but they can be difficult to light in windy conditions or when your hands are wet or cold. Lighters are windproof and easy to use, but they can run out of fuel or break. Flint and steel are reliable and can be used to start fires in any weather condition, but they require practice and skill to use effectively. Magnesium fires are powerful and can start a fire quickly, but they produce sparks that can ignite nearby flammable materials.

Section 2: The Fire Triangle
To start a fire safely and efficiently, you need to understand the fire triangle. The fire triangle consists of three elements: fuel, oxygen, and heat. To start a fire, you need to supply all three elements in the right proportions.

Tinder is the first element of the fire triangle. Tinder is any material that burns easily and quickly. Examples of tinder include dry leaves, grass, paper, and cotton fabric. Kindling is the second element of the fire triangle. Kindling is any material that burns slowly and steadily. Examples of kindling include small twigs, branches, and pine needles. Fuel is the third element of the fire triangle. Fuel is any material that burns slowly and steadily. Examples of fuel include logs, branches, and wood chips.

Section 3: Building a Fire
To build a fire safely and efficiently, you need to follow these steps:

1. Choose a safe location for your fire. Make sure it is away from flammable materials such as trees, buildings, and vehicles.
2. Clear the area of any leaves, sticks, and other debris that could ignite and cause a fire to spread.
3. Gather tinder, kindling, and fuel. Use dry materials that will burn easily and steadily.
4. Create a teepee or log cabin shape with the kindling and fuel. This will help contain the fire and allow air to circulate around it.
5. Light the tinder with a match, lighter, flint and steel, or magnesium fire. Use a gentle touch to avoid wasting fuel.
6. Add more fuel as the fire grows. Be careful not to smother the fire, which will suffocate it and make it difficult to start again.
7. Maintain the fire by adding fuel and adjusting the tinder and kindling as needed.

Section 4: Safety Precautions
Starting a fire can be dangerous if you don't take precautions. Follow these safety tips to ensure that you and your surroundings stay safe:

1. Always use caution when starting a fire. Keep a fire extinguisher or water source nearby in case of an emergency.
2. Never leave a fire unattended. Keep an eye on it at all times to prevent it from getting out of control.
3. Be aware of local fire restrictions and follow them. Some areas may prohibit open fires during dry seasons or when there is a high risk of wildfires.
4. Always put out your fire completely before leaving the area. Drown the fire with water or dirt, and stir the mixture until it is cold to the touch.

Glossary:
- Tinder: Any material that burns easily and quickly. Examples include dry leaves, grass, paper, and cotton fabric.
- Kindling: Any material that burns slowly and steadily. Examples include small twigs, branches, and pine needles.
- Fuel: Any material that burns slowly and steadily. Examples include logs, branches, and wood chips.

Conclusion:
Starting a fire safely and efficiently requires knowledge and skill. By understanding the fire triangle, choosing the right materials, and following safety precautions, you can start a fire that will provide warmth, light, and cook food efficiently. Apply these skills to new problems and situations, and you will be able to start a fire safely and efficiently in any environment.

To this end, Vevo censors the content of some of its videos for language, to make them more acceptable to advertising partners such as McDonald’s. The…

Video innovators OK Go have released yet another spectacular state-of-the-art video, which has already generated over 5M views on YouTube alone. The band teamed up with Morton Salt to produce this magical slowmo clip, as part of the #GivingTuesday campaign.

Instagram remains one of the most important and relevant platforms to upload video content. But which creators are generating the most views on the site? We bring you right up-to-date with last month's most watched Instagram Video Creators Leaderboard.

Video content should always aim to be entertaining, or informative, but given the nature of social video, it is critical that it also contains an element of conversation. When a creator or brand can rally a community around a video, they can amplify the reach of the video far more than the video could have done on its own.

Music is one of THE most popular categories on YouTube, and the video site is a very powerful promotional tool for both amateur, and professional, musicians. Competition is fierce, but you don't have to be Taylor Swift to generate views and engagement if you follow some simple advice.

YouTube wants to capture a slice of the music streaming market with its MusicKey service, but its main competitor in that field, Spotify, is firing back by introducing video content to its own platform, including music videos, news and entertainment, and original content from providers like Comedy Central and Tastemade.

David Letterman's legendary 'Late Show' residency ends tonight, and we take a look at 10 of the most viewed Letterman clips on YouTube. His innovative approach to the genre not only blazed a trail for other 'traditional' broadcasters, but gave the viewing public an appetite for compelling content which millions of online video creators are fulfilling.

A brilliant new Chrome app from musiXmatch allows you to sing along with the lyrics to almost any music video that's been uploaded to YouTube. With a database of over 7 million song lyrics, and some impressively accurate software, it's the best way to find the lyrics to a song on YouTube by far.

OK Go's music videos on YouTube have been watched more than 218 million times. Several of their videos have upwards of 20 million views, making them the masters of viral music videos. Here are 5 tips to be learned from OK Go, the superstars of music video innovation.

Music has always played an important role on YouTube, so it comes as a surprise that the video site is rumored to be strong arming indie labels into terms that undervalue the worth of their artists to the site. it's also a bit of a slap in the face to Indie labels who, like VEVO, have helped keep millions of viewers on YouTube.

186.1 million Americans watched online videos last month, that's very slightly down from March 2014, but Google sites still dominate the video content properties chart, and VEVO still maintains its rock-solid lead as the YouTube channel with the most unique views.

comScore's Online Video Rankings are out for March 2014, and they confirm that 187 million Internet-connected Americans watched 46.6 billion online videos, including 28.7 billion video ads. VEVO, ZEFR, Maker and Disney were the top YouTube channels for unique viewers.

Experian broke out mobile video viewing in their latest report along with some info on what ages are watching, when they watch, where they watch (as in site and app) and whether or not they feel video ads on smartphone or tablet are useful. Want to put a wager on which demographic thought them most useful and which said least?

The new year has not started out right for the online video industry with numbers dropping across the board in terms of viewers, minutes and ads. But is this an actual depression or just the late winter/post-holiday blues for the online video industry? With the release of comScore's February Video Ranking numbers we can find out what's going on. We do know that AOL is the #1 video ad property site again though and that Maker Studios reclaims the #2 YouTube channel spot.

Amazon wants to set your TV on FIRE! Oh, wait, they announced the Fire TV, that must be why they have been doing all that Kindle-ing. They have priced their OTT device at $99 but it comes chock full of tech and has the content to back it up. So the question is, will it generate a response with its intended audience, and will the competitors, pardon the pun, fire back?

Chromecast is a handy little device but if you want to get the most out of it you are going to want to install a ton of apps that will let you stream and beam content from your PC or mobile device straight to your TV screen. Luckily, there are already some great apps on the market, with the promise of more to come.

Lesson: Introduction to Genetics

## Section 1: Theoretical Concepts

Genetics is the study of how traits are passed down from one generation to another. It is the foundation of modern biology and medicine. Genes are segments of DNA that determine specific traits such as eye color, hair type, and height. There are four types of genetic inheritance: autosomal dominant, autosomal recessive, X-linked recessive, and mitochondrial inheritance.

## Section 2: Practical Examples

We can use genetics to understand the inheritance patterns of certain diseases such as sickle cell anemia. This is a genetic disorder that affects the shape of red blood cells. It is caused by a mutation in the hemoglobin gene, which leads to the production of an abnormal form of hemoglobin. This mutation is autosomal recessive, meaning that an individual must inherit two copies of the mutated gene (one from each parent) to develop the disease.

## Section 3: Real-World Scenarios

Genetics plays a crucial role in public health. For example, the NHLBI has funded research on fruit flies to better understand human sleep patterns. By studying the genes responsible for sleep in fruit flies, scientists can gain insights into similar genes in humans. This knowledge could lead to new treatments for sleep disorders such as insomnia and sleep apnea.

## Glossary

- Genetics: The study of how traits are passed down from one generation to another.
- Gene: A segment of DNA that determines a specific trait.
- Autosomal dominant: A type of genetic inheritance where only one copy of the mutated gene is needed for the trait to be expressed.
- Autosomal recessive: A type of genetic inheritance where both copies of the gene must be mutated for the trait to be expressed.
- X-linked recessive: A type of genetic inheritance where the mutated gene is located on the X chromosome.
- Mitochondrial inheritance: A type of genetic inheritance where the mutated gene is located in the mitochondria.
- Hemoglobin: A protein in red blood cells that carries oxygen from the lungs to the rest of the body.
- Insomnia: Difficulty falling asleep or staying asleep.
- Sleep apnea: A condition where breathing repeatedly stops and starts during sleep.

## Conclusion

Understanding genetics is essential for understanding how traits are passed down from one generation to another. By studying genetics, we can learn more about diseases such as sickle cell anemia and find new treatments for sleep disorders. This knowledge can also help us make informed decisions about our health and the health of our families.

Evaluation by differential scanning calorimetry of the effect of acid, ethanol, and NaCl on Escherichia coli.
The influence of acid, ethanol, and NaCl on the cellular components and inactivation of Escherichia coli were evaluated using differential scanning calorimetry. Cell viability was assessed using plate counting. The thermal stability for ribosomal subunit denaturation and the total apparent enthalpy decreased with increasing ethanol, salt, and acid concentrations. The reduction of the ribosomal subunit denaturation peak was the primary contributor to the decrease in the total apparent enthalpy. Thermograms indicated that even at concentrations at which less than a 0.4-log reduction of cell viability with a concomitant minimal reduction of total apparent enthalpy occurred, a decrease in onset temperature of ribosomal transition was evident. Acid treatments at pH 3 induced by HCl and by 0.4 M acetic acid caused the DNA denaturation temperature in vivo to decrease. Application of chemical treatment prior to heat treatment noticeably reduced the viability of E. coli cells at all the heat treatment temperatures (60, 62.5, and 65 degrees C) compared with that of heat treatment alone, suggesting an increased sensitivity of bacteria to heat treatment. Differential scanning calorimetry in vivo can be used to assess the effectiveness of hurdles when thermal processing technologies with hurdles are designed.

Lesson: Introduction to Differential Scanning Calorimetry (DSC)

**Objective:** To introduce students to the concept of Differential Scanning Calorimetry (DSC) and its application in evaluating the effect of acid, ethanol, and NaCl on Escherichia coli.

**Overview:** Differential Scanning Calorimetry (DSC) is a technique used to study the physical and thermal properties of materials. In this lesson, we will learn about the principles of DSC, its application in evaluating the effect of acid, ethanol, and NaCl on Escherichia coli, and how this information can be used to understand the behavior of other materials.

**Section 1: Introduction to Differential Scanning Calorimetry**

- What is DSC?
DSC is a technique used to measure the heat flow into or out of a material as a function of temperature or time. It is commonly used to study the thermal properties of materials, such as glass transition temperatures, melting points, and crystallization temperatures.

- How does DSC work?
DSC works by placing a sample and a reference material in a temperature-controlled environment. As the temperature changes, the heat flow between the sample and reference materials is measured. The resulting data is used to calculate the heat capacity, heat of fusion, and heat of transition for the material being studied.

**Section 2: Application of DSC in Evaluating the Effect of Acid, Ethanol, and NaCl on Escherichia coli**

- Why is DSC used to study the effect of acid, ethanol, and NaCl on Escherichia coli?
DSC is used to study the effect of these substances on E. coli because they can cause changes in the physical and thermal properties of the cells. By measuring the heat flow between the cells and a reference material, we can determine how these substances affect the cells' thermal stability and viability.

- What are the results of the study?
The results of the study show that the thermal stability of E. coli decreases with increasing concentrations of acid, ethanol, and NaCl. The reduction of the ribosomal subunit denaturation peak was the primary contributor to the decrease in the total apparent enthalpy. Even at concentrations at which less than a 0.4-log reduction of cell viability occurred, a decrease in onset temperature of ribosomal transition was evident. Acid treatments at pH 3 induced by HCl and by 0.4 M acetic acid caused the DNA denaturation temperature in vivo to decrease.

**Section 3: Practical Examples and Applications**

- How can DSC be used in other fields?
DSC can be used in various fields, such as materials science, pharmaceuticals, and food science. For example, it can be used to study the melting point of polymers, the glass transition temperature of plastics, or the stability of drugs.

- How can the principles of DSC be applied to real-world scenarios?
The principles of DSC can be applied to real-world scenarios to understand the behavior of materials under different conditions. For example, by studying the thermal properties of a new polymer, researchers can determine its suitability for use in high-temperature applications.

**Glossary**
- DSC: Differential Scanning Calorimetry
