In collaboration with our partners element14, Elektor Academy is excited to bring you the 24th of our monthly webinars, bringing us to our two year anniversary! Don’t miss out on this momentous milestone!

It's quite straightforward to build up some hardware and write test software with libraries available for the Arduino UNO, on the other hand it's not that easy to do the same thing "right" in Embedded Linux. This month’s presenter, Robert Berger asks the question

“Wouldn't it be nice to reuse this tested hardware prototype and write code for Embedded Linux to talk to it?”

A highly respected and experienced embedded real-time expert and embedded training consultant, Robert consults and trains people across the globe in order to help them create better software. You can expect top-notch, professional quality guidance, as Robert explains,

“I intentionally don't want to use Arduino wrapping libraries on Linux since those are typically not industrial strength, but targeted towards hobbyists. This is what's going to be presented here”.

The prototyping hardware is not only able to convert signal levels from an Arduino UNO (shield) to a Beagle Bone, but also to convert signal levels from a Beagle Bone (cape) to an Arduino UNO.

# Lesson: From Arduino Uno to BeagleBone Black (and back)!

## Introduction
 In this lesson, we will learn about the process of transitioning from an Arduino Uno to a BeagleBone Black (and back) for embedded systems development. We will cover the basics of both platforms, their similarities and differences, and how to write code for each. By the end of this lesson, you will have a solid understanding of how to use both platforms for your embedded systems projects.

## Section 1: Arduino Uno
### What is Arduino Uno?
Arduino Uno is an open-source electronics platform based on easy-to-use hardware and software. It is designed for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. The Arduino Uno board can be used to develop stand-alone applications or to interface with software running on a computer.

### How does Arduino Uno work?
The Arduino Uno board is based on a microcontroller called the ATmega328P. This microcontroller has a built-in program memory, data memory, and input/output pins. The Arduino Uno board also includes a USB-to-serial converter, which allows you to communicate with the board over a USB connection.

### Writing code for Arduino Uno
To write code for Arduino Uno, you can use the Arduino IDE (Integrated Development Environment). The Arduino IDE is a cross-platform application that runs on Windows, Mac OS X, and Linux. It includes a code editor, a message area, and a widget that shows the status of the board.

### Example project: Blinking LED
Here is an example project that blinks an LED on the Arduino Uno board:

```
// Set pin 13 as output
pinMode(13, OUTPUT);

// Blink the LED at a frequency of 1 Hz
void setup() {
  // Initialize the LED pin as an output
  digitalWrite(13, HIGH);
}

void loop() {
  // Turn the LED on
  digitalWrite(13, LOW);
  // Delay for 500 ms
  delay(500);
  // Turn the LED off
  digitalWrite(13, HIGH);
  // Delay for 500 ms
  delay(500);
}
```

This code sets pin 13 as an output, turns the LED on and off at a frequency of 1 Hz, and delays for 500 ms between each blink.

## Section 2: BeagleBone Black
### What is BeagleBone Black?
BeagleBone Black is a low-cost, single-board computer developed by Texas Instruments. It is designed for embedded systems development and is based on the ARM Cortex-A8 processor. The BeagleBone Black board comes with a variety of peripherals, including USB, HDMI, Ethernet, and audio.

### How does BeagleBone Black work?
The BeagleBone Black board uses a microprocessor called the AM3359 from Texas Instruments. This microprocessor has a clock speed of 1 GHz and includes a graphics processing unit (GPU) and a video decoder (VD). The BeagleBone Black board also includes a variety of peripherals, such as USB, HDMI, Ethernet, and audio.

### Writing code for BeagleBone Black
To write code for BeagleBone Black, you can use the Debian-based operating system that comes pre-installed on the board. You can also use the Angstrom distribution, which is a version of Linux optimized for embedded systems.

### Example project: Blinking LED
Here is an example project that blinks an LED on the BeagleBone Black board:

```
#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>
#include <fcntl.h>
#include <errno.h>

int main(int argc, char *argv[])
{
    int fd;
    char buffer[1];

    fd = open("/sys/devices/platform/leds/green:amber", O_RDWR);
    if (fd < 0) {
        perror("open");
        return 1;
    }

    write(fd, "on\0", 4);
    usleep(100000);
    write(fd, "off\0", 4);
    usleep(100000);

    close(fd);
    return 0;
}
```

This code uses the `open()` system call to open the file descriptor for the green/amber LED. It then writes "on" and "off" to the file descriptor to turn the LED on and off. The `usleep()` function is used to delay for 100 ms between each blink.

## Section 3: Transitioning from Arduino Uno to BeagleBone Black (and back)
### Similarities and differences
Both the Arduino Uno and BeagleBone Black are popular platforms for embedded systems development. However, there are some key differences between the two platforms:

- Hardware: The Arduino Uno is a microcontroller-based platform, while the BeagleBone Black is a single-board computer based on a microprocessor. The BeagleBone Black has more peripherals than the Arduino Uno, such as USB, HDMI, Ethernet, and audio.

- Software: The Arduino Uno uses the Arduino IDE, while the BeagleBone Black uses a Debian-based operating system. The BeagleBone Black also includes support for Android development.

- Programming language: The Arduino Uno supports C and C++ programming, while the BeagleBone Black supports C, C++, and Python programming.

### Reusing code and hardware
Despite these differences, it is possible to reuse code and hardware between the Arduino Uno and BeagleBone Black. For example, you could write code to control an LED on both platforms using the same code. You could also use the same hardware components on both platforms, such as sensors or actuators.

## Conclusion
In this lesson, we learned about the Arduino Uno and BeagleBone Black platforms for embedded systems development. We covered the basics of both platforms, their similarities and differences, and how to write code for each. By reusing code and hardware, you can transition from the Arduino Uno to the BeagleBone Black (and back) with ease.

ELISA estimations of rheumatoid factor IgM, IgA, and IgG in sera from RA patients with high disease activity. DTT treatment studies.
Although Elisa assays detecting rheumatoid factor's (RF) show high sensitivity and specificity, difficulties with IgA- and especially IgG-RF testing in ELISA systems, due to interaction from 'contaminating' IgM-RF is still thought to be a problem. Sera from 15 Rheumatoid Arthritis patients with high disease activity and high IgM-RF values were Dithiothreitol (DTT) treated. IgM-RF values were reduced to approximately zero in all tested sera. IgA-RF activity declined as expected, but also showed a statistically significant correlation between % reduction after DTT treatment and the IgM-RF value from the same serum sample. IgG-RF also decreased after DTT treatment, most pronounced for high IgG-RF values. A correlation (not statistically significant) between the % reduction in IgG-RF after DTT treatment and the IgM-RF value from the same serum sample was observed. Pepsin and Diethylammonium ethyl (DEAE) reduced the IgG-RF activity even more than after DTT treatment of the sera. Fractionation by Gel filtration of 8 serum samples showed that all the RF activity were found according to the 'first top' of the gel filtration curve.

Lesson: Introduction to Immunology and Rheumatoid Arthritis

### Section 1: Overview of Immunology and Rheumatoid Arthritis
Immunology is the study of the immune system, which is responsible for protecting our bodies from infections and diseases. Rheumatoid arthritis (RA) is an autoimmune disease that causes inflammation and pain in the joints. It occurs when the immune system mistakenly attacks the body's own tissues, leading to swelling and damage to the joints.

### Section 2: The Immune System and Rheumatoid Arthritis
The immune system is made up of cells, proteins, and organs that work together to defend the body against infections and diseases. The main components of the immune system are the lymphatic system, the spleen, the thymus, and the bone marrow. In RA, the immune system produces a protein called rheumatoid factor (RF), which attacks the joints and causes inflammation.

### Section 3: ELISA Assays and Rheumatoid Factor Testing
ELISA (enzyme-linked immunosorbent assay) is a laboratory technique used to detect the presence of specific substances, such as antibodies, in blood samples. ELISA assays are commonly used to detect RF in people with RA. However, there are some challenges associated with testing for IgA- and IgG-RF in ELISA systems, due to interactions from "contaminating" IgM-RF.

### Section 4: DTT Treatment Studies
To overcome this challenge, researchers have conducted DTT treatment studies on sera from RA patients with high disease activity and high IgM-RF values. DTT is a chemical compound that breaks disulfide bonds in proteins, allowing them to separate into their constituent amino acids. By treating the sera with DTT, the researchers were able to reduce the IgM-RF values to approximately zero in all tested sera. This treatment also led to a decrease in IgA-RF and IgG-RF activity, most pronounced for high IgG-RF values.

### Section 5: Fractionation by Gel Filtration
To further investigate the relationship between IgM-RF and IgG-RF, researchers performed fractionation by gel filtration on eight serum samples. This process separates proteins based on their size and charge. The results showed that all the RF activity was found in the fraction containing high molecular weight proteins, suggesting that both IgM-RF and IgG-RF may be involved in the same immune response.

### Glossary
- Immune system: the body's defense system against infections and diseases
- Autoimmune disease: a condition in which the immune system mistakenly attacks the body's own tissues
- Rheumatoid arthritis (RA): an autoimmune disease that causes inflammation and pain in the joints
- Rheumatoid factor (RF): a protein produced by the immune system in people with RA
- ELISA: enzyme-linked immunosorbent assay, a laboratory technique used to detect specific substances in blood samples
- IgA-RF, IgG-RF, and IgM-RF: different types of RF detected in ELISA assays
- DTT: diethylthiodicarbonate, a chemical compound used to break disulfide bonds in proteins
- Fractionation: a process used to separate proteins based on their size and charge

### Conclusion
In summary, this lesson has introduced the concept of immunology and rheumatoid arthritis, discussed the role of the immune system in RA, and explored the challenges associated with testing for RF in ELISA assays. We also learned about DTT treatment studies and fractionation by gel filtration, which have been used to better understand the relationship between IgM-RF and IgG-RF. By understanding these concepts, we can gain a deeper appreciation for the complexities of the immune system and the challenges associated with diagnosing and treating autoimmune diseases like rheumatoid arthritis.

We Are Tea - Review

Angela MooreMonday, June 03, 2013

We Are Tea,
founded by husband and wife team, Spence and Suzy, they opened a teashop in the
heart of London in 2007. The teashop
offered a unique and valuable opportunity for Spence and Suzy to engage first
hand with the consumer and perfect their tea blends prior to launching their
retail range. This coupled with their philosophy of ethically sourcing top
quality whole-leaf teas direct from artisan producers and hand-packing them in
the UK, has resulted in their multi-award winning teas securing their first
multiple retail listing.

You all know I love a cup of tea, and when it comes to tea everyone has their preference. We Are Tea’s
range of teas are organised into a unique colour-coding system to help
differentiate between the types. For example teas in the ‘black tea’ section
offer strength and depth of flavour and are a great way to start the day while
teas in the ‘green tea’ section are generally lighter and more delicate. A helpful guide for novice tea drinkers.

I was sent Chamomile Flowers, Gunpowder Supreme, Ceylon with
Vanilla, Earl Grey Supreme, Revitealise and Super Berry to run my taste buds
over.

There is a clear description for each tea, detailing the
ingredients for each special blend. There is no guidance on exactly how long
you should brew each tea, as this is a very individual choice. When it comes to
strength everyone differs while some people like flavour brewed long that packs a punch others
enjoy a mere tickle. Ooh I like that, in future I shall have to ask 'How
do you like your tea? - a tickle or a punch!' Ha ha.

Tea bags Usually when you have a special blend of tea, it's loose in a tin. You then have to brew this in a teapot before pouring through a strainer. But with We Are Tea available inbiodegradable whole-leaf teabags you get to enjoy a special special cup of tea even at your desk at work.

So far I have tried the following teas:-

Ceylon with Vanilla

Whole-leaf black tea carefully scented with real vanilla. True to its
description it gives you the impression of indulging in a sweet treat, if you
like sugar in your tea but want to cut back on the sweet stuff then this is the
tea for you. It is light, refreshing and the vanilla gives it almost a sweet
taste. I brewed this tea for approx 6 minutes and served without milk or sugar.

Earl Grey Supreme

A blend of the finest whole-leaf black teas scented with oil of bergamot and sprinkled with cornflowers. This was a delight to drink, I was wary about it being strong so only brewed this for one minute (just a tickle) without milk or sugar. It had great flavour and then the taste of oil of bergamot came through. I think I would choose this over the Ceylon with vanilla, this is more of a tea to drink every day.

I am looking forward to trying the remaining tea, in fact I am taking a few of them to work.

But you do not have to just take my word for the teas tasting beautiful in only 4 years We Are Tea have been awarded 36 Great Taste Awards.

Lesson: Introduction to Tea

## Section 1: Theoretical Concepts

Tea is one of the most popular beverages in the world. It is made from the leaves, buds, and stems of the tea plant, Camellia sinensis. There are several ways to prepare tea, including steeping, boiling, and brewing. In this lesson, we will explore the different types of tea, how they are produced, and the health benefits associated with drinking tea.

## Section 2: Practical Examples

Let's start by looking at the different types of tea. There are four main types of tea: black, green, white, and oolong. Black tea is made from fully oxidized leaves, while green tea is made from unoxidized leaves. White tea is made from young leaves and buds that are not yet open, and oolong tea is partially oxidized.

To produce tea, the tea plant is harvested and the leaves, buds, and stems are processed in different ways depending on the type of tea being produced. For black tea, the leaves are fully oxidized, which means they are exposed to air for several hours before being dried. For green tea, the leaves are quickly heated to stop the oxidation process. White tea is simply dried after being harvested. Oolong tea is partially oxidized, meaning it is exposed to air for a short period of time before being dried.

## Section 3: Real-World Scenarios

Now let's look at some real-world scenarios where tea can be enjoyed. Many people enjoy a cup of tea in the morning as a way to wake up and start their day. Tea can also be enjoyed throughout the day as a way to relax and unwind. In addition, tea can be used in cooking and baking to add flavor to dishes.

## Glossary

- Camellia sinensis: The tea plant
- Oxidation: The process of exposure to oxygen
- Leaf: The part of the tea plant that is used to make tea
- Bud: The small, undeveloped flowers of the tea plant
- Stem: The supportive structure of the tea plant
- Steeping: The process of soaking tea leaves in hot water
- Boiling: The process of heating water to a high temperature
- Brewing: The process of making tea by steeping or boiling tea leaves in water

## Conclusion

In conclusion, tea is a delicious and healthy beverage that can be enjoyed in many different ways. By understanding the different types of tea, how they are produced, and the health benefits associated with drinking tea, we can appreciate this ancient beverage even more.

**Lesson: Introduction to Closed-End Funds**

**Objective:** To introduce students to the concept of closed-end funds and their characteristics.

**Glossary:**
- Closed-end fund: A type of mutual fund that is not continuously offered after its initial offering and trades like a stock on the open market.
- Mutual fund: A professionally managed investment vehicle that pools money from many investors to purchase securities such as stocks, bonds, and other assets.
- Preferred stock: A class of stock that has priority over common stock in receiving dividends and in case of liquidation.
- Fixed income security: A financial instrument representing a loan made by an investor to the issuer, payable upon demand or at a fixed date.

**Section 1: Introduction**

Closed-end funds are a type of mutual fund that is not continuously offered after its initial offering and trades like a stock on the open market. They are created when a sponsoring company, typically an investment firm, raises a large amount of money from investors and uses it to buy a diversified portfolio of securities. After the initial offering, the fund is no longer open for new investors, and its shares are traded on the open market.

**Section 2: Characteristics of Closed-End Funds**

1. Limited number of shares: Closed-end funds have a limited number of shares outstanding, which means that their share prices can be more volatile than those of open-end funds.

2. Trading at a premium or discount: Closed-end fund shares often trade at a premium or discount to their net asset value (NAV), which is the value of the fund's assets minus its liabilities. This means that the market price of the shares may be higher or lower than their actual value.

3. Focus on specific sectors: Many closed-end funds focus on specific sectors of the economy, such as healthcare or technology. This allows them to specialize in a particular area and potentially achieve higher returns.

**Section 3: Example of a Closed-End Fund**

John Hancock Funds has recently launched its eighth closed-end fund and its 12th closed-end fund in total. The John Hancock Preferred Income Fund III will seek high current income consistent with capital appreciation by investing at least 80% of its total assets in a diversified portfolio of investment-grade preferred and other fixed income securities.

**Section 4: Conclusion**

Closed-end funds are a type of mutual fund that offers several advantages over open-end funds. They allow investors to buy and sell shares on the open market, which can provide greater flexibility and liquidity. Additionally, closed-end funds can specialize in specific sectors of the economy, which can potentially lead to higher returns. By understanding the characteristics of closed-end funds and the example of the John Hancock Preferred Income Fund III, students can gain a solid foundation in this investment vehicle.

Polymers and drugs suitable for the development of a drug delivery drainage system in glaucoma surgery.
Implantation of a glaucoma drainage system is an appropriate therapeutic intervention in some glaucoma patients. However, one drawback with this approach is the fibrotic tissue response to the implant material, leading to reduced flow of aqueous liquid or complete blockage of the drainage system. As a basis for developing an aqueous shunt we report here investigations with poly(3-hydroxybutyrate) (P(3HB)) and poly(4-hydroxybutyrate) (P(4HB)) as polymer matrices and with paclitaxel (PTX) and triamcinolone acetonide (TA) as drugs that might, in combination, delay or prevent the process of fibrosis by reducing fibroblast activity. P(3HB) and P(4HB) were fabricated into test prototypes with 500 μm outer and 200 μm inner diameter and ∼1 cm length. The antiproliferative agent PTX and the anti-inflammatory agent TA were incorporated into the polymer matrices and were released by diffusion. In vitro cell assays demonstrated that the polymers have the potential to reduce fibroblast viability, while TA showed differential inhibition of Tenon fibroblasts, but not cornea keratocytes. Implantation of polymer disks and prototype devices into rabbit eyes confirmed the good biocompatibility of the materials. The combined use of a poly(hydroxybutyrate) polymer with PTX or TA has the potential to reduce the fibrosis associated with conventional glaucoma drainage systems.

The hydrocarbon feedstocks, the raw materials used in petroleum refining industry, need to be refined before they can be used in numerous products and processes. A large part of the hydrocarbon feedstocks are submitted to a so called hydrotreating process. The purpose of hydrotreating is to reduce the amounts of impurities in the hydrocarbon feedstocks.
In particular, hydrotreating aims the removal of sulfur and nitrogen compounds.
The hydrocarbon feedstocks often contain sulfur and nitrogen compounds. These compounds are responsible of the release of sulfur oxides and nitrogen oxides in the atmosphere when the hydrocarbon products are used as fuel and burnt. These sulfur oxides and nitrogen oxides are considered harmful for the environment. As a consequence, national and international regulators are continuously imposing lower nitrogen and sulfur contents in fuel so as to reduce pollution of the environment by reducing as much as possible the quantities of these compounds when the fuel is burnt. There is thus an increased need to develop more efficient hydrotreating processes.
The efficiency of hydrotreating process relies in part on the activity of hydrotreating catalysts used. These catalysts allow converting feedstocks into useable materials. Nevertheless, during use, the activity of the hydrotreating catalysts decreases. The resulting spent catalysts may thus be used in less demanding kinds of hydrotreating processes after they are at least regenerated.
However, the regenerated catalysts do not show as high activity as the original catalysts due to agglomerates of the catalyst metals formation.
Numerous processes have been developed in order to reactivate the spent catalysts such as for example the so called rejuvenation process. The rejuvenation aims to restore the original activity of the catalysts or at least an activity superior to the one obtained after a simple regeneration step. However, the efficiency of the rejuvenation process may depend on several parameters such as: the catalyst to be treated, the operational conditions of the process or the rejuvenating agent used.
Thus, there is still a need to develop efficient and easy to implement processes for restoring the activity of the spent catalysts.

textbook:
Lesson: Hydrotreating Process

### Introduction

Hydrotreating is an essential process in the petroleum refining industry. It is used to remove impurities such as sulfur and nitrogen compounds from hydrocarbon feedstocks. This process helps in producing cleaner fuels that emit fewer pollutants when burned. In this lesson, we will learn about the hydrotreating process, its purpose, and its significance in the petroleum industry.

### Section 1: What is Hydrotreating?

Hydrotreating is a chemical process that uses hydrogen gas to remove impurities from hydrocarbon feedstocks. The process involves contacting the hydrocarbon feedstock with hydrogen gas under high pressure and temperature conditions. The hydrogen molecules react with the sulfur and nitrogen compounds in the hydrocarbon feedstock, breaking them down into simpler compounds.

### Section 2: Purpose of Hydrotreating

The primary purpose of hydrotreating is to remove sulfur and nitrogen compounds from hydrocarbon feedstocks. These compounds can cause environmental pollution when the hydrocarbon products are burned as fuel. By removing these compounds, hydrotreating helps in producing cleaner fuels that emit fewer pollutants and meet regulatory standards.

### Section 3: Significance of Hydrotreating

Hydrotreating plays a crucial role in the petroleum industry as it helps in producing high-quality fuels that are safe for the environment. The process also helps in meeting regulatory standards set by national and international organizations to reduce pollution. Additionally, hydrotreated products have better performance characteristics, such as improved lubricity and reduced emissions, making them suitable for various applications.

### Section 4: Practical Examples

One practical example of hydrotreating is the production of ultra-low-sulfur diesel (ULSD). Diesel fuel contains sulfur compounds that, when burned, produce sulfur dioxide (SO2), a pollutant that contributes to air pollution and climate change. By using the hydrotreating process, sulfur compounds in diesel fuel can be removed, resulting in ULSD with significantly lower sulfur content. This fuel burns cleaner and produces fewer emissions, reducing air pollution and helping to mitigate climate change.

Another example is the hydrotreating of heavy oils and bitumen to produce lighter, more valuable products such as gasoline or diesel. This process helps in upgrading the quality of heavy oils and bitumen, making them suitable for use as fuels or feedstocks in other industrial processes.

### Section 5: Self-Debating Discussion

Why is hydrotreating important in the petroleum industry?

Answer: Hydrotreating is essential in the petroleum industry because it helps in producing cleaner fuels that emit fewer pollutants when burned. By removing sulfur and nitrogen compounds from hydrocarbon feedstocks, hydrotreating contributes to reducing air pollution and meeting regulatory standards set by national and international organizations. Additionally, hydrotreated products have better performance characteristics, making them suitable for various applications.

### Glossary

- Hydrocarbon: A compound consisting of hydrogen and carbon atoms.
- Hydrogenation: A chemical reaction in which hydrogen molecules add to a substance, typically an alkene or alkyne, to produce a hydrocarbon.
- Sulfur oxides: A group of compounds containing sulfur and oxygen, such as sulfur dioxide (SO2) and sulfur trioxide (SO3).
- Nitrogen oxides: A group of compounds containing nitrogen and oxygen, such as nitric oxide (NO) and nitrogen dioxide (NO2).
- Ultra-low-sulfur diesel (ULSD): A type of diesel fuel with significantly lower sulfur content than conventional diesel fuel.

### Conclusion

In conclusion, hydrotreating is a vital process in the petroleum industry that helps in producing cleaner fuels by removing sulfur and nitrogen compounds. This process contributes to reducing air pollution and meeting regulatory standards. By understanding the purpose and significance of hydrotreating, we can appreciate its importance in the production of high-quality fuels and its impact on the environment.

The placement of medical devices, such as vascular stents, within the vascular system of a patient to give vessels added structural stability is a well known and increasingly common procedure. In fact, a large number of differing stents and other prosthesis have been developed for deployment within the vascular system for this purpose. In practice, devices of this nature are often inserted over a prepositioned guide wire and advanced into the vessel until the device reaches a predetermined deployment site. Generally, the route over which the stent or other device must be advanced is often long and quite frequently very tortuous.
Sometimes, during the deployment of a vascular stent or prosthesis, it may happen that the stent will be inadvertently positioned in an incorrect location. Alternatively, it may happen that a stent or other device will outlive its useful life. In these and other cases, it may become necessary to retrieve the stent from within the vascular system for removal from the patient. Unfortunately, the removal of a stent from the vascular system can be a difficult process. For one thing, removal generally requires dragging the stent back through the tortuous route by which the stent was originally deployed. When doing so, it may happen that the stent will catch, or snag, on various anatomical features within the vascular system. As a result, there is a danger that the removal process will actually traumatize the involved vessel.
The difficulty associated with stent removal is often compounded by the lack of medical instruments which are designed for the specific task of stent removal. More specifically, it is generally the case that removal of stents, and other medical prosthesis, will often be accomplished using makeshift instruments. For example, the snaring or snagging of a stent for removal from a vessel is often accomplished using a hooked instrument which has been improvised at the time of the actual procedure. As may be expected, however, expediently made instruments are often difficult to use and may cause additional vascular trauma if the hook is allowed to contact the vessel wall. Additionally, when these devices are employed, there is an ever present danger that the stent or prosthesis will become disconnected from the retrieval device during the retrieval process. A disconnection of this type further increases the difficulty and risk associated with the removal process.
In light of the above, it is an object of the present invention to provide a device for retrieving a stent from the vessel of a patient which can grip onto and hold the stent during its removal from the vessel. Another object of the present invention is to provide a device for retrieving a stent from the vessel of a patient which can minimize traumas to the vessel during the removal process. Yet another object of the present invention is to provide a device for retrieving a stent from the vessel of a patient which is simple to use, relatively easy to manufacture and comparatively cost effective.

Lesson: Understanding Medical Devices in the Vascular System

## Section 1: Introduction

In this lesson, we will learn about medical devices used in the vascular system to provide structural stability. We will discuss the types of devices, their functions, and the procedures involved in inserting them into the body.

## Section 2: Types of Medical Devices

There are several types of medical devices used in the vascular system, including:

1. Stents - These are small mesh tubes that are placed inside blood vessels to keep them open. They are commonly used to treat blockages caused by plaque buildup in the arteries.

2. Prosthesis - These are artificial devices that are used to replace damaged or missing parts of the body. In the vascular system, prosthesis can be used to replace damaged blood vessels or valves.

3. Catheters - These are thin, flexible tubes that are used to insert medical devices into the body. They are commonly used in procedures such as angioplasty and stent placement.

4. Guide wires - These are thin, flexible wires that are used to guide medical devices into the body. They are commonly used in procedures such as angioplasty and stent placement.

## Section 3: Procedures Involved in Placing Medical Devices

1. Preparation - Before inserting a medical device into the body, the patient must be prepared. This includes cleaning the skin and injecting a local anesthetic into the area where the procedure will be performed.

2. Insertion - Once the patient is prepared, a guide wire is inserted into the blood vessel. The guide wire is then used to guide the catheter and other medical devices into the correct position.

3. Deployment - Once the medical device is in place, it is deployed using a balloon or other mechanism. The device expands to fit the shape of the blood vessel, providing structural stability.

4. Removal - If necessary, the medical device can be removed using a similar procedure to the one used to insert it.

## Section 4: Importance of Proper Positioning

Proper positioning of medical devices is crucial to ensure that they function correctly and do not cause further harm to the patient. Incorrect positioning can lead to complications such as blood clots, stroke, or heart attack.

## Section 5: Glossary

- Stent: A small mesh tube that is placed inside blood vessels to keep them open.
- Prosthesis: An artificial device that is used to replace damaged or missing parts of the body.
- Catheter: A thin, flexible tube that is used to insert medical devices into the body.
- Guide wire: A thin, flexible wire that is used to guide medical devices into the body.

## Conclusion

Understanding the types of medical devices used in the vascular system and the procedures involved in placing them is essential for anyone interested in healthcare or biomedical engineering. By learning about these devices and their functions, we can better understand how to treat and prevent vascular diseases.

In this lesson, we will learn about environmental zones, air pollution, and their impact on our health and the environment. We will also explore the measures taken by governments to reduce air pollution in urban areas.

Section 1: What are Environmental Zones?
Environmental zones are areas where certain restrictions are imposed on vehicles to reduce air pollution. These zones are usually established in urban areas where air pollution is a major concern.

Section 2: Why do we need Environmental Zones?
Air pollution is a serious problem that affects not only our health but also the environment. It is caused by various factors such as industrial emissions, transportation, and energy production. Environmental zones help reduce air pollution by restricting the number of vehicles in an area or by prohibiting certain types of vehicles from entering the zone.

Section 3: How do Environmental Zones work?
Environmental zones work by imposing restrictions on vehicles based on their emissions standards. For example, in Cologne and Bonn, vehicles with certain EURO classes are not allowed to enter the blue environmental zone. This means that only vehicles that meet the latest emissions standards can enter the zone.

Section 4: What are the benefits of Environmental Zones?
The benefits of environmental zones are numerous. Firstly, they help reduce air pollution, which improves the quality of the air we breathe and reduces the risk of respiratory diseases. Secondly, they encourage people to use public transportation or other means of transportation that do not contribute to air pollution. Finally, they provide an economic incentive for businesses to invest in cleaner technologies.

Section 5: What are the challenges of Environmental Zones?
One of the main challenges of environmental zones is that they can be difficult to enforce. For example, in Cologne and Bonn, diesel driving bans were repeatedly decided by the court because some vehicles were not excluded from the zone. Another challenge is that some people may find it inconvenient to use public transportation or other means of transportation that do not contribute to air pollution.

Section 6: How can we apply what we learned?
We can apply what we learned by being mindful of the impact of our actions on the environment. For example, we can choose to walk or bike instead of driving when possible. We can also support policies that aim to reduce air pollution and promote sustainable transportation options.

Conclusion:
In conclusion, environmental zones and other measures to reduce air pollution are essential for protecting our health and the environment. By understanding the importance of environmental zones and their impact on our daily lives, we can take action to make a positive difference.

**Lesson: Using Element Groups in Webflow**

**Introduction:**

In this lesson, we will learn about Element Groups in Webflow. We will explore what they are, how to use them, and why they are useful. By the end of this lesson, you will be able to create your own Element Groups and use them effectively in your Webflow projects.

**Section 1: What are Element Groups?**

Element Groups are a powerful feature in Webflow that allow you to group together multiple elements and then reuse those elements across multiple pages in your website. Think of them as a way to create reusable components that you can drop onto any page in your site.

**Section 2: How do I create an Element Group?**

To create an Element Group, follow these steps:

1. Open the Elements panel in Webflow by clicking on the "+" icon in the top left corner of the screen.
2. Click on the "Group" button in the Elements panel. This will open up a new window where you can name your Element Group.
3. Drag and drop the elements you want to include in your Element Group into the new window.
4. Once you have added all the elements you want, click on the "Create Group" button.

**Section 3: Why use Element Groups?**

There are several reasons why you might want to use Element Groups in your Webflow projects:

1. Reusability: With Element Groups, you can create reusable components that you can use on multiple pages in your site. This can save you a lot of time and effort when building your website.
2. Consistency: By using Element Groups, you can ensure that all instances of the same element on your site look the same. This can help improve the overall consistency of your site.
3. Organization: Element Groups allow you to keep all the elements related to a particular component in one place, making it easier to find and edit them later.

**Section 4: Practical Examples**

Let's say you want to create a navigation bar that appears on every page of your site. Instead of manually adding the same elements (links, logo, etc.) to each page, you could create an Element Group containing all the elements you need for the navigation bar. Then, whenever you add a new page to your site, you can simply drop the Element Group onto that page and it will automatically include all the necessary elements.

Another example might be a footer section that appears on all pages of your site. You could create an Element Group containing all the elements you need for the footer (such as copyright information, social media links, etc.), and then simply drop the Element Group onto each page to ensure consistency across your site.

**Section 5: Conclusion**

Element Groups are a powerful tool in Webflow that allow you to create reusable components and maintain consistency across your site. By understanding how to use Element Groups effectively, you can save time and effort when building your website, while also improving its overall organization and design.

the raindrops of life… some warm, some storm

Breathing room

The work program gives a bonus stipend for successfully starting a job… about a bonus two weeks if you’ve had good attendance, reduced some for each absence or discipline problem.

I’d been told this was put in after your first day of working the job… to make sure you actually are going to go through with it. Which then gets added to the pay period, and given on the next paycheck. Meaning, mine wouldn’t be until the 4th.

I’d actually been specifically told mine would be on the 4th.

Except… it showed up today… having been put in when I got the job and trusting that I would be serious and follow through.

Maybe seeming like a small difference…. but when the budget is really tight… and I was wondering how things were going to work out on paying for gas if things were timed poorly on first paychecks…
(if pays every two weeks, and doesn’t have a short time between hours going in and check coming out, could be up to 3 or 4 weeks before money in hand catches up with hours being worked)

Sometimes a little bit of trust, giving a lot more breathing room to make things work, seems like a big gift of mercy!

Not even sure which of the staff people to thank on this one… but maybe that’s best, as right now I’d be overly gushy till they’ll probably wonder what my deal is.. lol
