May I introduce Tim Berners-Lee?

Since I devoted a lot of time and effort to my Culture Paper which is about "Great American Entrepreneurs", I decided to introduce to you another great entrepreneur in this blog post. But I don't want you to be bored to hear about Americans all the time, so I am now going to write about a British entrepreneur.

Born and raised in London, Tim Berners-Lee studied physics at the University of Oxford for about three years, but in the end became a computer scientist. Tim is best known for being the inventor of the World Wide Web.
Berners-Lee had been working as a software engineer at CERN in Geneva, Switzerland, for several years. In 1989 he came up with the idea of the WWW. Coming from all possible continents, the people working at CERN were gathering in Geneva in order to work on their projects. After returning to their home countries, they wanted to keep in touch and exchange data. Doing so over the telephone or via air mail was both pricey and laboriously. Tim unterstood their problem and thought of an idea how to connect the computers they were working with, even when being a thousand miles away from each other. Thereupon Tim Berners-Lee invented three technologies which are today the basis of the World Wide Web:
  1. HTTP (Hyper Text Transfer Protocol) is a protocol that defines how information is transmitted and tells, so to say, the web browsers and servers what to do. The acronym "http" or "https" is placed in front of every Internet address (URL).
  2. HTML (Hypertext Markup Language) is a language used for creating web pages. The language consists of certain elements which are "read" by the web browser (Google Chrome, Mozilla Firefox, Internet Explorer, Safari, etc.).
  3. URI (Uniform Resource Identifier) identifies the name and location of a resource (e.g. a file or a Internet address). A URI would look like this: /images/bernerslee.jpg, whilst a URL, which is similar to the URI, would look like this: http://www.blogger.com/images/bernerslee.jpg.

Based on these three technologies, Tim Berners-Lee created the World Wide Web. The world's very first website, info.cern.ch, was launched in 1991 and outlined the concept of the WWW. If you like to read more about the invention of the World Wide Web, feel free to visit this website. Or you could watch this TED video of Tim Berners-Lee talking about his invention. It's about 16 minutes, but it's definitely worth watching.




Today, Berners-Lee is a professor in the Electronics and Computer Science Department at the University of Southampton (UK). Also, he founded and is currently leading the World Wide Web Consortium (W3C), an organization working on the development of the WWW. Although Berners-Lee invented today's most dominant communication medium, he is not considered one of the wealthiest persons in the world.

Being a Paramedic For One Day

Hey guys! :-)
Since we're currently covering the topics Health and Medicine, I would like to tell you how a typical 12-hour shift within the Ambulance-Services looks like. As you might have read in some of my preceding blog posts, I work as a voluntary paramedic at the Austrian Red Cross in Linz. I've made the experience that lots of people don't really know what a paramedic does all day long. Most of them assume a paramedic works in a hospital. That's completely wrong! So let yourself plunge into my world of  "being a paramedic (for one day)".

06:30 am - Getting ready for the shift

A typical shift starts at 7 am, which is why you need to check if the ambulance car you'll be driving with is OK. What does that mean? Within an ambulance car, you have a number of various equipment. All this equipment needs to be checked if it's working (e.g. the stretcher [folding bed used to transport the injured]), if it's still usable (e.g. the antiseptic) or how much oxygen you still have aboard (see the portable oxygen cylinders in the second picture). If everything's alright, you tell the dispatchers (the ones who take the calls and then send out the vehicles) by radio that you are available. Have a look at the pictures what we have in our ambulance cars (among lots of other stuff).



 

07:00 am - Ready to rumble!

Now that the dispatcher knows we're on standby, we might receive a call soon. We don't know what's going to happen next or which kind of patient we're going to get. Maybe it's just an elder woman who is living alone, toppled and can't stand up on her own. Or we assume the worst and we could be sent to a car accident. Anything can happen!

7:44 am - Our fist mission

Beep, beep the radio goes. It's time to save the world.

Yeah, About that phrase... Many people become a paramedic because they believe they are going to save the entire world. Not quite. I don't know about my colleagues, but I have never saved the whole world before. And I suppose I won't do so any time soon. Being a paramedic isn't always about saving someone's life. Instead, we provide first aid in order to relieve the suffering of individuals. Frequently, we pick up our patients at home to bring them to the hospital. For instance: A patient has their leg in a plaster cast and can't go to the hospital on their own. In order to make the doctor's appointment at the hospital happen, we fetch the patient and transport them there. So let's not say we save the world, but rather try to ease someone's pain by giving first aid or giving someone a ride.

Have a look at the picture on the right hand side. This is what our terminal looks like. For those of you who speak German, you'll find that no trouble to understand. There are a few abbreviations, though, which even German speakers might not be familiar with.

So let's have a closer look:
EO stands for Einsatzort, which means the place where something happened (e.g. an accident) and we therefore need to go to in order to help our patients; the Irish Red Cross calls it the incident location.
Dia stands for Diagnose, which means diagnosis. In this particular case we have a patient who suffers from Tachykardie (tachycardia). The prefix tachy- says that something is accelerated whilst cardio/cardia is always linked to the heart. If we have problems with our heart, for example, we would see a cardiologist.
Pat stands for Patient (patient). Our dispatchers always suggest to which hospital our patient should be brought. In this case it says nach AKH. That means we'll bring our patient to the general hospital.
KEO stands for Koordinaten Einsatzort and tells us the exact coordinates of our incident location.
In the very last line we come to know that a GP had a look at the patient already and finds it necessary to bring him to the hospital. (HÄND war vor Ort).

How will we treat our patient?
Our patient suffers from tachycardia, which means that their heart beats really really fast right now. First of all, we will tell our patient to breathe calmly. One of us will feel their wrist to check the pulse. A normal heart beat is about 80 (+/- 20) per minute. Our patient has a pulse of 130(!). We also take their blood pressure, which turns out to be at a normal rate (120/80). The most important thing now is to quickly bring our patient to the hospital. While driving to our destination, the patient should sit up straight as that's easier to breathe. After the patient is brought to the emergency room, we will drive back to our station and hopefully have some coffee there.


10:13 am - The next mission's certain to come.

After having a longer break at the station, the radio beeps again. This time, the beep goes way faster and louder. There are two different radio sounds: the slower one tells us that it's not a matter of life and death, but the faster one does. So we'll finish our coffee quickly and get started.

On our terminal we get to know the following: In the first line the dispatchers tell us that we have to turn our flashing blue light on ("Blaulicht"). The diagnosis says bewusstlos, which means unconscious. In the penultimate line we get to know that a doctor on emergency call is going to be there as well ("NEF 1 ebenfalls").

Since our patient is unconscious, we need to place them in recovery position. I am not going to explain here what the recovery position is about. If you like to read a more detailed explanation how to place someone in recorvery position, have a look at one of my previous blog posts called "How to place someone in Recovery Position". What's more is that we will administer oxygen to our patient in order to make their breathing easier. We'll also cover our patient with a blanket made of aluminum. We don't want them to feel cold, do we?
Generally speaking, since a doctor was sent to the incident location too, he's the one to call the shots. We'll place the patient on the stretcher, of course still being in recovery position, and set off. After dropping the patient off at the emergency room, we drive back to our station and have a break.



12:30 pm - Enjoy your meal!

I'm starving! When volunteers work the day shift, they get coupons to get free lunch at one of the hospitals in Linz. Most of the time, we receive coupons from the "Landes- Frauen- und Kinderklinik" - a hospital that emphasizes on toddlers, children and expectant mothers.

This is how a typical lunch in a hospital looks like. What do you think about it? Does it look delicious to you? Would you call it "gourgeous" as Jamie Oliver always does?




04:47 pm - Last but not least.

What we have here is something that we experience in almost every (night) shift: alcohol abuse. No, we're not the ones , but our patient. Sadly, like in every bigger city, there are people living in a poorhouse or even on the street. Actually, we don't transport these kind of patients to the hospital because they have a problem with alcohol. Instead, we bring them there because when they are drunk, they do silly things like sleeping outside or trip and fall. We neither want them to feel cold, nor do we want them to bleed or feel pain. 

It can be a bit nerve-wracking to pick up a drunk guy who talks a lot of nonsense or might even be aggressive. In case a patient is aggressive, I call the cops so that they escort us to the hospital. It's a lot more secure for us paramedics to have a police officer on our side.

What will we do with this patient?

Well, the most important thing is to, again, bring the patient to the hospital. Before that we'll feel their wrist to check the pulse and take a blood sample so as to measure their blood sugar. If the person had been sleeping outside, we make sure to cover them with a blanket. Otherwise the patient might suffer from hypothermia. What does that mean? Hypo always refers to something that is below a normal frequence or value. In contrast, hyper means that something is above a certain value. "Thermia" refers to temperature, which means that hypothermia is when your body temperature gets low so that it even might endanger yourself.


06:45 pm - Exhausted, but satisfied.

Our shift is drawing to an end. For twelve hours we've been available for people in need. We didn't exactly save the world. Instead, we tried to ease people's pain and bring them to the hospital. That's actually a lot. Even when we're quite exhausted right now, we can be proud of ourselves!

If you have any questions on that, please don't hesitate to text me! :-)

10 foods that keep you hale and hearty

Hey guys! :-)

As I might have told some of you before, I am living in a dorm in Graz and therefore cooking for myself. I always try to have lots of vegetables, fruit and other nutritious crops. I've been browsing through the web a lot lately and found some interesting information about foods that are essential for a healthy diet:

1. Green Tea

http://www.deltalabsusa.com/assets/client_files/images/Photos/Food%20and%20Drink/green-tea.jpgHealth benefits: Reduces skin damage, reduces level of stress, ideal for losing weight

Green tea consists of certain antioxidants that prevent cell damage and slow down skin aging. According to a Swiss study, people's brains were much more active in the working and memory areas when drinking green tea. Additionally, green tea allows you to calm down and relax. A Japanese study found out that the levels of stress were 20% lower in people who drank green tea than in people who did not. Green tea is a smart substitution for sugary drinks and therefore ideal for losing weight. That is because green tea changes the metabolism so that more calories are burnt.

Tip: Green tea should not be prepared with hot boiling water, but rather with water between 160 and 170 degrees. Otherwise, some important vitamins and antioxidants get lost. Adding one or two slices of lemon would be a good idea. Lemons contain loads of vitamin C which make the compounds of green tea way easier to absorb. Make sure not to combine green tea with dairy products (like milk or yogurt), as they make the absorbing process harder for your stomach.


2. Dark Chocolate

http://i247.photobucket.com/albums/gg158/MDA2008/MDA%202011/dark_chocolate.jpgHealth benefits: Decreases fatigue, reduces level of stress, helps treat depression, relieves menstrual cramps

According to a recent research, 1.5 ounces (some 28 grams) of dark chocolate a day for two weeks immensely reduces the stress level. Milk chocolates can be helpful as well, but not as much as the dark one. Chocolate contains antioxidants which are better absorbed without milk added. Besides, studies have shown that eating a few pieces of dark chocolate three times a week can lower blood pressure. It also improves the blood flow resulting in a significant decrease of risk of arteriosclerosis.
As you might be aware of already, chocolate makes you happy and boosts your mood. Chocolate even contains substances that could potentially make you high. But you would have to eat between 20 and 30 kg (200 to 300 bars of chocolate) to eventually become high!

Tip: Keep in mind that dark chocolate, or chocolate in general, should be consumpted in moderation because it is high in sugar. 


3. Bananas

http://romanlosangelez.files.wordpress.com/2014/01/banana2.jpgHealth benefits: Lowers blood pressure, helps reduce incontincene, relieves menstrual cramps, regulates blood pressure, promotes bone health

Bananas have a lot of health benefits. To illustrate, it prevents the bones from becoming thin and weak. Additionally, according to a study, fresh bananas protect the stomach from developing wounds or even ulcers. That is because bananas promote the production of a thicker mucus that prevents stomach acids. Bananas are also helpful for elimination problems and diarrhoea. By containing a high amount of pectin and fiber, bananas help normalize the movement of the digestive tracts and therefore ease constipation. Consuming three or more fruits per day reduces the risk of age-related vision loss. Especially bananas are fruit that protect your eye sight.


4. Whole grains

http://www.jessainscough.com/wp-content/uploads/2011/05/wholegrains.jpgHealth benefits: Increase concentration, ideal for losing weight

Whole grains like wheat, oats, einkorn or quinoa are ideal for losing weight. When trying to lose weight, products like whole wheat flour, bread or pasta can be really helpful. What's more is that whole grains boost concentration, especially when you have whole grain cereals for breakfast. It helps you to stay focused. Skipping breakfast results in poor concentration and fatigue, so try to have breakfast every day. In addition, whole grains reduce the risk of diabetes.

Quinoa: Quinoa is packed with proteins, magnesium and iron and a grain crop that is easily digestible. What's more is that Quinoa is gluten-free and helps relieve migraines. The NASA considered Quinoa an optimal crop for long-duration space flights.

Oats: Oats is a cholesterol-lowering grain that consist of calcium, magnesium and other essential vitamins. Basically, oats lack gluten. They are, however, grown next to wheat and other grains so that they are contaminated with glutens. So officially, oats is a gluten-containing crop.

Tip: What about starting the day with a healthy and delicious porridge?


5. Yogurt

http://cdn1.scdlifestyle.com/wp-content/uploads/2010/08/how-to-make-yogurt-1.jpgHealth benefits: Helps relieve indigestion, prevents osteoporosis

Yogurt is rich in bacteria and calcium that helps your stomach digest and reduce constipation and diarrhoea. Along with that, yogurt lowers the risk of osteoporosis, which is an illness that weakens bones and increases the risk of unexpected fractures. Combined with vitamin D, yogurt has a positive effect on bone mass. Vitamin D can be found in eggs, oily fish like sardines and salmons or powdered milk. In some yogurts, vitamin D is already added.

Tip: Enjoy your yogurt with fruit as they contain a lot of vitamins and add a pleasing taste.


6. Maca

http://www.organicmeetsgood.com/wp-content/uploads/2013/04/maca-2.jpgHealth benefits: Boosts concentration, prevents sexual dysfunction, promotes fertility

Maca, a root vegetable which looks similar to a radish, helps to balance hormones. Some consider it an aphrodisiac as it might also arouse sexual desire. The root helps women with menstrual problems and prepares them for pregnancy by supplying certain hormones. Moreover, maca serves as an energy and concentration boost.

The plant originally comes from Peru. Some hundred years ago, the Inca consumed maca as a vegetable due to its nutritional values. They boiled, fried, roasted or dried the root and even ate it to prevent lung problems.


http://www.supergreenlandmarket.com/1/wp-content/uploads/2012/12/leafy-greens.jpg 7. Leafy greens

Health benefits: Boosts concentration, prevents cell damage

Leaf vegetables such as broccoli, spinach, lettuce, arugula, asparagus or cabbage are brimming with fiber and vitamin E. They help you to keep mentally focused and prevent your brain cells from damage. Leafy greens are low in calories and fat and high in proteins, magnesium and other vitamins. Especially spinach, which is known to be Popeye the Sailor's favourite vegetable, is rich in iron, calcium and other nutrients. Also cabbage is good for your digestion and heart and is believed to lower the risk of cancer. Generally speaking, leafy greens are very low in calories. One-half cup of cabbage, for instance, contains only 15 calories.

Tip: If you're not really fond of leaf vegetables, try to add them to dishes that you like. You might also want to try out new vegetables like Swiss chard, mustard greens, bok choy, celery, watercress, ...


8. Garlic

http://detoxforlife.biz/wp-content/uploads/2014/04/garlic.jpgHealth benefits: Relieves common colds, protects blood cells, prevents sexual dysfunction

Garlic, also known as "the stinking rose" due to its pungent smell, reduces the chance of catching a cold and also helps to recover from a cold. What's more is that garlic boosts your mood and improves sexual performance. Besides, garlic is a great source or vitamin C and able to keep your blood pressure under control. By protecting your blood cells and vessels it prevents you to suffer from inflammatory.

Tip: It's most effective when you eat garlic raw.


9. Fish & Seafood

http://instantpot.com/wp-content/uploads/2009/06/sea-food.jpgHealth benefits: Relieves common cold, relieves migraine, prevents sexual dysfunction

Fish and seafood strengthen your immune system and lessens the frequency of catching a cold. When having a cold or the flu, oily fish like salmon, mackerel and tuna help a lot. Fatty fish like sardines, herrings and trouts, however, reduce the frequency of migraines. Since Inuits have low levels of heart diseases, eating fish regularly might protect the heart and lower the amount of cholesterol. As you might know, fish contain Omega 3 which lowers the chance of inflammations, protects against Alzheimer and recudes the symptoms of ADHD.

Shellfish: By containing a great amount of vitamin B12 and zinc, shellfish reduce the risk of miscarriage.

Oysters: Oysters are rich in zinc and therefore also considered as a aphrodisiac.


10. Nuts

http://www.nutstop.com/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/d/e/deluxe-mixed-nuts-roasted-unsalted.jpgHealth benefits: lessens sleep problems, prevent coronary heart diseases

Nuts are loaded with vitamins which reduce the chance of suffering from a coronary heart disease. Most nuts might possibly be able to lower the risk of cancer, but that's not scientifically proven yet.
Walnuts: Especially walnuts improve the quality of sleep. Additionally, the fruit helps the body to protect itself against Parkinson, Alzheimer or type-II diabetes. Some important vitamins in walnuts cannot be found in any other food, which makes this kind of fruit quite special.
Almonds: While being rich in vitamin E, magnesium and calcium, almonds lower cholersterol and the risk of suffering a heart disease.

Tip: It's healthier to eat them raw and with the skin as more than 90% of the vitamins are found in the nuts' skins.
