Asbestos is a mineral composed of microscopic, malleable fibres. These fibres are heat, corrosion and electricity resistant. This resistance makes asbestos a good insulator and its fibrous structure means it can be used in building materials such as cement, roofing, or flooring.
However, this comes with risk. Every individual fibre of asbestos is composed of even smaller fibrils that can break off into the air when disturbed. Exposure to this toxic substance is highly dangerous, inhaled airborne fibres can be permanently trapped in lung tissue.
These fibres will cause you to develop serious diseases and cancers over a long period.
Because these afflictions progress over such a long period by the time they are diagnosed it is often too late to recover from. That is why it is important to know the dangers of asbestos exposure and how to keep yourself safe.
Mesothelioma will cause a malignant tumour to form in the lung lining after inhaling asbestos. This type of cancer can spread to the lining of the surrounding abdomen, heart, ovaries and testes.
The symptoms include the shortness of breath and pain when breathing, eating or coughing. Pressure on vital organs by the tumour and fluid build-up causes these symptoms.
After diagnosis, patients in England have a survival rate greater than 44.5% for the first twelve months. The survival rate at five years is around 6.5%. Treatment is through chemotherapy, radiotherapy, surgical treatment or palliative care.
Asbestos Lung Cancer
Only a small percentage of lung cancer is exclusively caused by asbestos. However, exposure will increase the risk of developing lung cancer from other sources such as tobacco smoking.
Inhaled asbestos will be lodged into lung tissue where the fibres will cause genetic damage to the cells, turning them cancerous. Much like with Mesothelioma this will develop over a long time. Additionally after developing it takes only a period measured in months for it to spread around your body.
Unlike Mesothelioma the cancer is formed inside of the lungs rather than the lining.
Symptoms of asbestos lung cancer include a wheezing cough, coughing up blood and chronic respiratory infections.
Depending on the patient’s overall health and how far cancer has spread treatment could be: chemotherapy, radiation therapy, immunotherapy or surgical removal.
However, the number of deaths from asbestos-related cancer is still high, being similar to the 2018 estimate of 2446 deaths by mesothelioma in the UK.
After exposure over the course of 20 to 30 years, excessive scar tissue will replace regular lung tissue.
This lung scarring causes symptoms such as coughing, shortness of breath and extreme fatigue.
This is because so much damage has been inflicted to the lungs that it reduces the lungs capabilities. With scarred lungs, the exchange oxygen is made more difficult which leads to tiredness.
Additionally, asbestosis has the unfortunate effect of setting into motion other conditions. This complicates your situation further by making you more likely to suffer from the pleural disease, Mesothelioma and asbestos-related lung cancer.
There is no cure for this. It is not possible to reverse the damage suffered by your lungs. Treatment to relieve the symptoms includes oxygen therapy or pulmonary rehabilitation.
Pleura are the two-layered membrane lined sacs in the chest cavity between the lungs and the ribs. Inhaled asbestos fibres that find their way here will cause scarring, much like that found in asbestosis. This scarring will cause the thickening to be found in the pleura.
A thickened pleural will cause issues such as shortness of breath, discomfort within the chest. This is because the swelling will squeeze the lung itself as it covers a large area and restricts the expansion of the lungs.
Asbestos is so dangerous because it causes cancers and diseases that are not instantly apparent that are difficult if not impossible to deal with whilst posing a significant threat to your lifespan. Despite the asbestos ban, the substance can still be found in a lot of buildings as is a regular occupational hazard for those that regularly work with older buildings.
With how dangerous asbestos is to the health of those around it a preemptive stance is best taken to avoid exposure to the harmful substance in the first place. Contact asbestos removal experts for their services to protect yourself from the dangers of asbestos exposure.
What You Need To Know About Ethiopian Coffee Beans
In this article, you are going to learn more about why Ethiopian coffee beans are so interesting to learn about, and why the country is worth the visit for coffee enthusiasts around the world.
Ethiopia might not be as big as Brazil and Colombia when it comes to the production of the international supply of coffee beans, but they are well-known to be one of the best countries if you want to get coffee. Coffee enthusiasts from all over the world visit this place in order to get its own unique strain of coffee beans, and simply because the coffee beans here are also superb in terms of its growth and overall quality.
After all, Ethiopia is considered as the country where coffee itself was found, and has its deep historical roots on how it got discovered. Some may think that coffee was found in
Colombia, but the country learned about coffee back in the 18th century only. But in the case of Ethiopia, coffee was discovered way back in the 9th century. Ever since then, Ethiopia became home to a wide variety of coffee beans, where some gained international fame and even became a signature coffee bean of other countries as these countries refined their ways of cultivating it.
The Renowned History Of Coffee Beans
It is not actually official if it’s true or not, but even neighboring countries claim the legend that Ethiopia was the place where coffee was first found. Believe it or not, it’s not some trader or researcher who stumbled upon this amazing fruit, but a goat farmer! Back in the 9th century, a goat farmer accidentally discovered the cherries of the coffee bean plant when he saw his goats consume it. He noticed his goats got too energetic unlike before when they never consumed the coffee beans. afr
As a result, he got curious if it also gives the same energy-granting properties to humans. That’s why he took some and shared it to the local monks in this place. Of course, they never know how to brew the fruit yet, so they consumed it first and realized that it can really grant them energy in a safe way. Over time, the method of consuming coffee beans eventually became the popular way that we all know about: turning it into an energizing and aromatic drink. As time passed by, word spread out about the properties of coffee and eventually gained worldwide fame that we all know about today.
Personally, this story about the discovery of coffee is really intriguing because who would expect that it was a farmer who discovered the wonders of the coffee beans by accident. History surely has a lot of unusual happenings that eventually laid an impact to a lot of people even to this day, and coffee seems to be one of them if this story is true.
The Importance Of Coffee In Ethiopia
The importance of Ethiopian coffee beans is not just all about the history that it had, and not just their strains that has a fruity flavor into it. The coffee industry of Ethiopia supplies 3% of the world’s overall coffee production. It might not be as huge as what Brazil can offer, but Ethiopia is still one of the holders of the industry’s foundation. Also, the U.S. happens to be one of the top buyers of Ethiopian coffee beans which are considered as the best African coffee beans.
In terms of the geographical importance of coffee in the country, take note that there are more than 1,500 square miles worth of coffee farms scattered throughout the country that’s dedicated for the cultivation and production of coffee beans. Just note the fact that the mountains where the farms are located have an altitude of up to 2,000 meters above the sea level. This environment is enough to grow the finest quality coffee beans. But of course, this also means that some of their coffee bean strains are considered as a luxury item due to its superb quality.

How do they make Nitrous Oxide?
Before we get to how they make nitrous oxide, we first got to learn what is Nitrous Oxide? Nitrous oxide, commonly known as laughing gas, nitrous, or nos, is a chemical compound, an oxide of nitrogen with the formula N2O. At room temperature or the temperature that adapted to its surroundings, it is a colorless non-flammable gas, that gives off a slight metallic scent and taste. At elevated temperatures or above normal oral temperature, nitrous oxide is a powerful oxidizer similar to molecular oxygen. Nitrous oxide has significant medical uses, more so present in surgery and dentistry, for its anesthetic and pain numbing effects. Better known by the masses as “laughing gas”, it received this name due to the euphoric effects a person experiences after inhaling it, with this property that has led to its use as a anesthetic. You can readily buy laughing gas but only for culinary purposes.
It is on the World Health Organization’s List of Essential Medicines, the safest and most effective medicines needed in a health system. Though it became popular as an anesthetic, nitrous oxide has so many other uses. It increases internal combustion engine power, serves as an oxidizer in experiments including chemicals and rockets, and it also acts as a propellant for foods including cooking spray and whipped cream, and has multiple uses in medicine showing that it has its flexibility in uses as a chemical compound.
After learning what is Nitrous Oxide, How does someone produce said gas? The basic and safe method to make nitrous oxide at home or in a small lab was discovered by a chemist named Humphry Davy. Davy discovered that through heating ammonium nitrate, it decomposes into nitrous oxide and water vapor:
NH4NO3 (s) → 2 H2O (g) + N2O (g)
While simple, it’s crucial to gently adjust the heat of ammonium nitrate between 170 °C to 240 °C (338 °F to 464 °F). Exceeding the maximum temperature leads to rapid decomposition and the glass container to shatter due to reaching its breaking point. Use small amounts of ammonium nitrate then control the temperature with a thermometer just to be safe.
1. Place a small amount of ammonium nitrate in a test tube. Cap the test tube with a one-hole stopped. Insert plastic or glass tubing into the hole and run it into a hot water bath. The water needs to be hot because nitrous oxide dissolves in cold water, reducing the amount collected. Collect the bubbles in an inverted jar. This setup for collecting gases is called a pneumatic trough. It condenses water produced by the reaction and removes impurities, like smoke.
2. Once you’ve set up the equipment, slowly heat the ammonium nitrate. You can do this over a flame or burner. Apply heat so that it does not exceed the maximum temperature and so it produces gas bubbles at the rate of one to two bubbles per second.
3. Stop heating the ammonium nitrate before all of it has decomposed. This helps prevent overheating. Turn off the heat and disconnect the tubing from the collection jar so that water won’t flow up into it. Cover the container before turning it upright, so you won’t lose the gas. You can seal the container while it is inverted or simply cover it with a flat sheet of plastic or glass before turning it over. The gas in the container is nitrous oxide, plus smaller amounts of other nitrogen oxides, such as nitric oxide and nitrogen monoxide. Exposure to air oxidizes the nitric oxide to form nitrous oxide.
This procedure is commonly used for commercial preparation of nitrous oxide, with acid and base treatments to further purify the gas.
In 1772, another method for making nitrous oxide was discovered by Joseph Priestley and he became the first person to synthesize nitrous oxide. Priestly collected the gas produced by sprinkling nitric acid over iron filings. While an effective method, this method is better attempted in a lab by scientists because nitric acid should be used under a fume hood, with proper gear to avoid accidents. Another method to make nitrous oxide in the home or lab is to heat a mixture of sodium nitrate and ammonium sulfate. Again, collect the gas using a pneumatic trough. Heating this mixture is even safer than decomposing ammonium nitrate.
2 NaNO3 + (NH4)2SO4 → Na2SO4 + 2 N2O+ 4 H2O
The chemical reaction between urea, nitric acid, and sulfuric acid also produces nitrous oxide.
2 (NH2)2CO + 2 HNO3+ H2SO4 → 2 N2O + 2 CO2 + (NH4)2SO4 + 2H2O
Here are tips to prepare nitrous oxide safely:
– Never exceed the temperature when heating ammonium nitrate over 240 °C or 464 °F.
– Turn of the heating apparatus before the last bit of ammonium nitrate has decomposed.
– Use the highest purity ammonium nitrate available for the safest method. Pure ammonium nitrate is more stable than ammonium nitrate with impurities.
– Perform the project in a lab or in a well-ventilated area if at home. Overexposure can be fatal.
Due to the dangers difficulty involved in making nitrous oxide yourself you will most likely want to just buy nitrous oxide from an online seller and have it delivered to you.
How to Become a Life Coach
You may have a passion for helping others pursue what makes them happy in life. Whether giving advice on a career change or how to overcome an obstacle, you thrive at helping people. Friends may have mentioned that you’d make an excellent life coach, and you’re ready to give it a shot!
To follow your dreams and become a life coach, here are some tips on how to get started.
1. Figure Out What Your Goals Are
Before diving into building your business, first, you should set some goals.
It’s essential to keep in mind that with any business, getting things rolling takes time. But the good news is that by having goals, you’ll have a clear starting point.
So work on coming up with some personal and financial goals. An example of a specific goal might be to get 15 new clients in two months.
Don’t make your goals unrealistic, but at the same time challenge yourself. After a few months have gone by, you’ll have a better idea of how things are going. From there, you can adjust your goals accordingly.
2. Consider How Much You Want to Spend on Startup Costs
Do you know how much becoming a life coach will cost? Before jumping in headfirst, it’s vital to understand how much money you want to spend.
If it’s a side hustle for you, you likely won’t have to spend a lot. But say you want life coaching to be your full-time profession. Then, you may need to fork out more money upfront.
You don’t have to spend a lot initially, but there are a few things you should budget for. For example, setting up a website would be a good idea. Spending money on advertising would also be helpful.
Advertising will help you get website traffic. Setting up ads is essential so that people learn more about you and your services. So, look into setting up an account on Google and Facebook.
It would help if you also considered getting business insurance. Liability insurance, in particular, is essential. With liability insurance, you’d have protection if you got sued for not giving good advice.
3. Use Social Media to Your Advantage
Advertising your services on sites like Facebook and Instagram certainly has its advantages as well. It’s effective because it drives traffic, but organic traffic is just as important! So with that being said, focus your attention on building a following on social media.
Social media is tricky, though. It’s impossible to be active on every social media platform. Being too involved often results in getting burned out!
So, it’s up to you to do some research and figure out where your audience hangs out the most. For example, if your audience tends to spend their time on Instagram, make an effort to be more active there. The same goes for LinkedIn.
Wherever potential customers are engaging, you should engage alongside them. If the opportunity presents itself, you can mention your services. Although, don’t feel like you have to be overly proactive. Frequently getting into a conversation with someone is enough. They’ll likely click over to your profile and learn more about you since you’ve been chatting.
4. Write on a Blog
As a life coach, you have a lot to offer! One way to showcase your skills is by starting a blog on your website. You can cover an array of topics, from how to jumpstart your business to how to recover from hardship.
Having a blog on your site offers other benefits, as well. For example, you can add ads to your site and use affiliate marketing as well. Promoting products and services from other companies can earn you money.
Besides earning money, affiliate advertising has another perk. You get to share the products that you believe in with your readers!
Having your blog gives you the power to choose what topics you want to discuss. Being in charge also gives you the final say on things like what type of products you wish to promote.
The truth is there really are no disadvantages to starting a blog on your website!
5. Continue Your Education
You may or may not decide to get a life coach certification. If you do, it’ll benefit you in the long run. You’ll be able to tell your clients that you’re certified in the area you’re coaching them in. Once they learn of your expertise, they’ll likely have more confidence in you! And they may be more willing to refer you to their friends as well!
Besides getting a certification, consider continuing your education in other ways. A few ways to soak up more knowledge are by reading, attending seminars, and going to workshops. You can also join Facebook groups and connect with other professionals in your field.
Honing your skills is something you should focus on as it will allow you to grow. Better yet, you’ll be able to provide better services to your clientele.
Becoming a life coach is no doubt a fulfilling career. You get to help people overcome obstacles and reach their highest potential.
It may take a while for you to get your coaching business up and running. But once you get the hang of things, you’ll find great success doing what you love!

CURRENT EDUCATIONAL ISSUES IN 2021
There are probably many things facing the education industry, some of which have persisted for years. However, in 2021, nothing has affected and threatened to cripple the whole space like the Covid-19 pandemic. Schools and educational centers have struggled to cope with the effects brought about by the pandemic. When it all started in 2020, it was panic stations all around and many students and teachers were thrown into confusion. Even though there are signs of normalcy returning to the world, some issues have been exposed more than others. Here are some of them.
1. Over 1 billion students have dropped out of school
There has always been a struggle to educate the masses, and while this was already going on, the pandemic has dealt a heavy blow to it. According to a UNESCO report, over 1 billion children stopped going to school when the pandemic hit and governments had to shut down schools to contain the pandemic. This has affected over 124 countries and accounts for over 70% of total students in schools. Of course many students have chosen to continue their education online with help from online platforms like AssignmentMasters that help many complete their school assignments.
2. Some Parents are now Homeschooling
This has been happening even before the pandemic hit us. But with the pandemic already here, parents who never thought of this have now been forced to do it to ensure their children don’t miss out on a chance to learn. However, questions are being asked about the effectiveness of this given that not all parents can actually teach. Some parents may be too busy to assign and mark assignmentholic.co.uk. Some may not even have the qualifications to do it.
3. Cancellation of Examinations
It took a while before many educational institutions could decide what direction to take as the pandemic hit our doorsteps. However, one of the toughest issues to tackle was whether to go on with high-stakes examinations or cancel them. This presented a curriculum quagmire that is still affecting many schools today. Some institutions reverted to online examination even as this presented a lot of challenges. Even so, many institutions had to find a way to do this or cancel the tests altogether.
4. Seniors in College and High School Lost Out
Even as some institutions canceled the end-year examinations, many senior students who were hoping to finish school found themselves in a closure quandary. Many who were hoping to finish their education and move on to the next phase of their lives were left disappointed and confused. This has led to many students despairing while others have sought alternative ways to finish their education. Many, however, have decided to take it on their chins and move on.
5. Too many online resources
While this may not sound like a bad thing, it may have challenges that may affect the quality of education offered. Many online platforms and groups have surfaced to try and provide a solution for those that have been adversely affected. The problem is that some of these platforms may not offer the best quality of learning needed. However, some like research paper writing services uk have been a cut above the rest in offering the best services for students and teachers. Even though some of these platforms offer quality services, the amount of platforms online has been overwhelming for parents, teachers, and students as well.
6. Inequities have been further exposed
Although this has been talked about for many years, the pandemic has exposed it even further; some schools and institutions have countless resources to offer students and caregivers while others have very little or none at all. These inequities have further exacerbated the situation. While some students can access essayontime.co.uk and have their essays done on time, some do not even have free internet to learn.
There are many more issues facing education today, some of which have been made worse by the pandemic. While many countries try to fight the disease and restore normalcy, the education industry has a long way to go to try and restore their own normalcy. Many teachers and students have had to adjust to many restrictions and the virus waves. As schools reopen in some countries, many questions still need answers.
