I read last week at SMHI's site that the spring bloom had started and are going on at full speed in the West Coast Sea. See picture from SMHI. http://www.smhi.se/nyhetsarkiv/varblomningen-igang-i-vasterhavet-1.29301

"On March 11, it was good conditions for satellite observations of algal blooms in the North Sea. Picture suggests high chlorophyll concentrations along the Swedish west coast. Satellite image from NASA's MODIS Aqua, processed by SMHI.'s Black Cloud or country."

Got a chance yesterday to go out to the west coast and after raking plankton. Now today on my biology lesson, we will analyze the algae we got hold of. It seemed clear to me that there were a lot of different "particles" in the water. It also seemed I got some water fleas / small crustaceans as well.

At the tip of Klädesholmen we see the rounded rocks. The ice sheet during the ice age did a masterly work.

 

 

 

Electrolysis 2013-03-20

We connected our carbon electrodes to a power source. We had a solution of sodium sulphate as an old familiar recipe precribes. We dripped BTB into it which is a pH indicator. Power on and at both electrodes, it bubbled slightly. At the anode, it became yellow, indicating that became acidic, hydrogen ions. At the cathode, it became blue, basic with hydroxide ions. Today when we rehearsed electrolysis pondering why the recipe prescribed sodium sulphat because we found that it did not participate in the reactions. We then tried to do the same with water alone. It was the same result but it took much longer time. One student suggested that we take common salt, sodium chloride. Said and done we did. Again the same result but it went faster, as fast as with sodium sulfate. See a close up picture of the electrolysis. From the beginning it was greenish colour in the solution.
 

When searching online, you always have sodium sulphat in this electrolysis. Why? I think it's just the case of a habit. Simply having water takes too long time, when there are ions in the water, it's faster, ions probably helps to convey the power.

Daily Mail had in England had a critical article about this? Some climate scientist thought the use of computer models that fit well with previous years should also be good at predicting the future. How it happened is shown in this graph. The global temperature has levelled of for 15 years. How much longerwill it take before it falls or rises. Everything in nature goes in cycles, it should not be forgotten. You can not just extrapolate a trend for decades into the future. See

A predator that has become a vegetarian. It is a species in the bear family living on bamboo, but will it find a little meat it  well to taste good to the panda. Its closest relative is the only bear in South Amaerica, Spectacled Bear who lives in northern Andes. It is estimated that there are between 5000 and 30000 of this bear. It is similar to the panda in that it eats mostly vegetarian stuff, fruit and shoots. Only 5-7% of the diet is meat as Wikipedia says. It is short faced like pandas. See picture.

In the case of pandas, we have been led to believe that it is endangered. But not today. In the wild, we know of over 1600 but others appreciate thenumber to 3000 based on DNA studies from feces. "In breeding center in Chengdu, they are now so numerous that they do not know what to do with them but pandas are useful in diplomacy," writes Eirik to me. It is 40% more than what they knew in the 90's. Pandas have always been rare. Best way to save them for posterity, of course, is to save their habitat. I've only seen a live panda once in my life. It was at the London Zoo in the 70s. A panda sitting relaxed and reclined and ate bamboo leaves. A peaceful predators that are solitary, meet each other only by mating. The giant panda I saw was sitting like the panda in the image below.

The most commonly cultivated plants besides the three wheat, corn and rice are shown in the table below.

http://www.agriskmanagementforum.org/sites/agriskmanagementforum.org/files/Documents/5-Parcher_WB2012.pdf

Pulses are beans / peas.If we go by weight, corn first, followed by wheat, rice, potatoes. Potatoes gives 17 tonnes per ha. No other crop can compete with potatoes in terms of yield per ha. Nr 10 on the list is bananas. http://www.businessinsider.com/10-crops-that-feed-the-world-2011-9?op=1

Rice comes in third place and is the largest crop in Asia. Rice harvest has increased substantially over the past 40 years. An example from Bangladesh. In 1971 they produced between 10 and 11 million tonnes of rice, now they produce about 25 million tons of rice on the same land. The population in the same period increased from 71 million to 135 million people. Yields have increased faster than the population.

Those areas do not change much over all in Asia. Even Alfred Russel Wallace said 100 years ago about Bali that they grow on each cm2 and there is hardly any place for wild plants. Thailand plans to increase its rice areal with 500 000 ha while Japan has abandoned the same amount of land, land more difficult to cultivate.
 
China is the largest producer and consumer of rice. Yields have increased a lot too. So much so that China has reduced rice area by 19 million hectares. Some of these secondary land has been abandoned and some are used for other crops. See http://factsanddetails.com/china.php?itemid=344

Forest land in China has increased from 8.6% in 1949 to 18.2% in 2003. According to
http://www.unc.edu/ ~ csong/Song2009-ChinaForestCoverBookChapter.pdf
 
This abandoning of marginal and not very fertile agricultural land is a phenomenon not only in Asia. In Puerto Rico, the proportion of forest land increased from 28% to 40% of the country.
http://userpage.fu-berlin.de/ffu/akumwelt/bc2008/papers/bc2008_46_Pares-EtAl-revised.pdf
 
The same trend in Nicaragua. Some countries in Africa are developing in the  opposite direction as for example Zimbabwe. They lost 21% of their forests between 1990 and 2005. Something that reflects the anarchy in this country where the old, crazy man Mugabe reigns.

Pangolins of the world 2013-03-13

The pangolins are poorly understood both by the public and by scientists. One reason is that they are nocturnal, shy away from people and not so spectacular. Youdon´t  see them often. They resemble anteaters but they are not related to them. They feed on ants and other insects. No one defends them but many Chinese people like to eat them, and their scales are used in traditional Chinese medicine. Some of the Asian species are endangered and need protection. Now, more recently people has begun to focus more on them and realized that the Asian species need protection. From all over Asia these animals are sent to China to be cooked and their scales are ground down to be used in medicine.

The TRAFFIC organization that keeps track of the trade in endangered species says that Saba, East Malaysia sent the 22,000 pangolins over 18 months and Vietnam sent in 2011 between 40 000 and 60 000 pangolins. These are estimates based on consignments stuck in customs.

Pangolins of the world

 

Afrika

• Manis gigantea - bright green, Central Africa, least concern
• Manis tricuspis - light green, Central Africa, near threatened
• Manis tetradactyla - dark blue, least concern
• Manis temmenicki - pure blue, least concern


Asia
• Manis crassicaudata - violet, indian, near threatened
• dactyla - Orange, China, endangered
• Manis javanica - pure cyan, East Asia, endangered
• Manis culionensis - pure red, Philippines, near threatened

 

Pangolins fetus is a delicacy in China

More warmer and earlier springs. Good isn´t it?

Iron Nights / frost nights in early June, has disappeared, at least in southern Sweden. Good isn´t it?
It was then in the old days people were guarding their ryefields, frost at night would come at the time of the rye bloom. Did it bloom when frost came there was no rye harvest and no rye bread. They lit fires at the small ryefields and they went along both sides of the fields and pulled with a rope so that the ears bent, that the  small sensitive ryeflowers would not freeze. Today, plant breeding also helped that we do nor need to go rye guarding.
Summers was not always warm, especially July. The average temperature in July, the last 30 years is about 2 degrees colder than in the 30 - 40 - and 50's in a great part of the country except in the mountainous area. Sad isn´t it? See my blog entry for 28 August.
http://rutgerstaaf.blogg.se/2012/august/sveriges-julitemperatur-2012-08-28.html
 

Overall, the summer was a bit colder than normal. The month of July was, however, at the last 30-yearly averages. But if we add June and August so it was overall a bit colder. For the whole summer temperature average in map form, there is not any one on SMHI pages so we can not get a real good picture of how it was in the southern half of Sweden.

Autumn is characterized by later frost nights. Good is´nt it?

When talking about climate change the average temperature is really not a good measure. To tell if it is bad or not, one must know how the heat is distributed over time and the country.

Auracaria a genus of coniferous trees best known from Australia and New Caledonia, but there is also the auracaria species in Brazil and Argentina. In the picture below you can see Auracaria bidiwillie also called Bunya tree, which is found naturally in southern Queensland near the coast. This Auracaria has the largest cones but all Auracaria species have large cones.

An Auracaria from Argentina is a very durable tree that you understand from this picture.

 

 

 

 

Silversword and other plants 2013-03-07

Look first at how a blossoming silversword looks. An impressive sight.

Source: http://www.cepolina.com/silversword-flower-volcano.html 

Hawaii has many special plants that are just there, they've evolved there. They are endemic to say.

91% of all plant species are endemic to Hawaii, the highest rate on the planet. This means that Hawaii is a good place to study the evolution of. Overall, there are 970 vascular plants there.
And number two, New Zealand with 81% of endemic species.
Number three is New Caledonia, with 76% of endemic plant species.
These three islands are in a class by itself along with New Guinea, where it is estimated that between 70 and 80% are endemic. All plants are not fixed there yet.

If we then go to other islands such as Cuba 46% is endemic, Jamaica 23%.
Galapagos Islands, you're probably wondering about that. There is 25% endemic species.
Had Darwin arrived in Hawaii, he had found even better study material for his theory of evolution.

But we must not forget that the Philippines has altogether 9253 plant species and where only 66% are endemic. I once read a scholar who wrote that the Philippines was much more interesting than the Galapagos Islands from the evolutionary point of view. http://www.conservation.org/where/priority_areas/hotspots/asia-pacific/Philippines/Pages/biodiversity.aspx

Sweden? Vascular plants include seed plants and spore plants as clubmoss, horsetails and ferns. In Sweden, anout 2,200 resident species of vascular plants are known, of which about 650 are stray species from cultivation and are established in the wild during the last two centuries. For just over 300 vascular plants included in ArtDatabankens and Swedish Botanical Society "floraväktarverksamhet" (gards of wild species), there has also been a very detailed basis for assessing the performance of the individual species populations, and the spontaneous reporting of finds recorded in the Species Gateway has provided significant additional ontribution of discovery sites. http://www.slu.se/Global/externwebben/centrumbildningar-projekt/artdatabanken/Dokument/R%C3%B6dlistan/Artgrupper/Rodlista2010-karlvaxter.pdf

650 plant species have thus man brought into our country during the last 200 years and I'm pretty sure that the monks during the Catholic period also brought in some  species. This means that humans have increased the botanical diversity of our country by about 42% over the past 200 years. Who is it that says that humans reduce biodiversity? There's both a plus and a minus account. 300 species are on the flora guardians track. Who is flora guardians in Sweden? Most retirees. Very few young people are flora guardians. We would need more young people.

Endemic species in Sweden? I have not found an exact list of this. They often mix species and subspecies. but it is said to be more than 30 endemic species in our country. We can blame the ice age for this small part. Time has been to short to evolve many endemic species. These endemic species are found in the mountains, on Öland and Gotland and along the Baltic coasts. An endemic species is Gymnadenia runei  an orchid more red than Brunkullan, a relative, found only in southern Lapland. This one was discovered in 1960 by "Rune" hence the name Gymnadenia runei. This Rune with first name Olof. See picture.

When the researchers visited this mountainous part of New Guinea, they found new species of various kinds. They also discovered that the unusual tree kangaroos even existed here even though they were not common despite the undisturbed nature. In New Guinea, there are 10 species of tree-climbing kangaroos and northern Australia there are a few more. All of these are in low numbers. In New Guinea there are about 10 000 of them. Their main enemy is humans who hunt and eat them. Other enemies are pythons in northern Australia and an eagle in New Guinea, but this eagle is mostly eating the possums. Otherwise, predation does not seem to play a major role in this part of the world. This applies especially to the beautiful paradise birds. An unusual situation.

The tree-climbing kangaroos are not as agile as monkeys but they are durable. They can jump to the ground from the trees at 30 meters height without injury. Sometimes they jump down when they get scared. The picture shows one of the tree-climbing kangaroos from New Guinea.

White blood cells 2013-02-28

Eosinophils, neutrophils, basophils, as some of these white blood cells are called. They are grainy in structure, but the most characteristic is that the nucleus is divided into different lobes so sometimes it looks like there are multiple cores, sometimes it looks like a U. We stained them with methylene blue.


As you may know, most of the white blood cells reside outside the blood vessels. We have in the body about 2.5 kg of white blood cells and approximately 1% are in our blood vessels. There is a concentration of them around our intestines, especially the colon. This is due to the large intestine where, where we have most of the approximately 1015 bacteria that we carry . 10 times more than our own cells. It is estimated that we have about 500 different species of bacteria in the large intestine. These we need to protect our body against and if we did not have our white cells or immune cells that we could call them, we would have no chance against the bacteria that is nature's smallest and most efficient decomposers. They would like to break down our body if they could. For them, we are only a large portion of wandering nutrition.

Neurons and synapses 2013-02-27

Each neuron can form synapses (connections) with up to 10,000 other neurons in an incredibly complex system. Nerve impulses can on the way pass one billion billion synapses. With these synapses and the circuts the memory will be storred. The memory capacity of the brain is today estimated to be between 1 and 1000 terabytes. The nerve impulse is electric and runs along the outside of the cell membrane, but when this impulse arrives at the synapse, then it is mediated by small molecules, neurotransmitter. See picture.
 
When you learn something at least 50 million synapses per second are formed, according to what I read earlier.

Recent research on the brain and genetics of this shows that humans have a superior ability to form synapses compared to other primates. This is by strengthening the best synapses and eliminate the less good synapses. Real efficiency.
The top of the gene activity behind the synapses is reached at five years in humans, unlike chimpanzees who reaches this at one year. "Our findings suggest that the human brain is extremely plastic and sensitive to environmental impact during the first five years of life," said one nerve cells and brainresearcher named Khaitovich. "Our study revealed a potentially important mechanisms involved in the early development of human cognition."

The research on nerve cells has also shown that a nerve cell must have the same impulse at least four times to form permanent synapses for memory to become what we call long-term memory and it requires many synapses to form a memory.

For the brain to learn things good brain must get many impulses. We need practice, practice and practice again for the brain. To be really good at something about 10,000 hours of practice are needed.

With this knowledge, I understand  Kairos Future's observation that brain research and pedagogics does not speak the same language, does not speak to each other. Homework and practice through training and re-training is not so popular. Students would like to find a shortcut that does not exist. Some schools like to highlight specific pedagogies to attract students. The first students ask about today at the school information about it on the natural science program if it is much homework. Studnets before  would never have dreamed of that question. We usually respond a bit vague.

If we start talk about this info that the school should follow the latest brain research and that there is much homework and exercises it would not be popular. But so it is.

Besides the teacher has to create a good environment for learning and Kairos Future has recieved the usual description from the students of a good teacher. He should be knowledgeable and committed, have humor but at the same time be strict and fair, that is able to keep track and order.

Various studies have shown that successful teachers are knowledgeable, passionate about their subjects, are interested in their students, thus engaged. What type of pedagogics used plays a minor role. Obviously using IT-technology is increasingly important today. But the personal knowledgeable and commitment is still as important. With this, Kairos Future pinpointed out a weak point.

 

 

 

Today's manufacturing jobs 2013-02-22

When you talk about manufacturing jobs to people they don´t think about high status work despite the fact that the dirty industrial jobs are gone. Today, many industrial jobs are qualified. As industrial workers, you might be an operator and perhaps manage a CNC machine. Cutting machines of various types but also with newer type technology as waterjet cutting and plasma cutting machine. You must be able to read CAD drawings and so on. Industrial work has become increasingly high-tech. Quality is extremely important, demands are high, complaints costs too much. Are you working with an assembly industry, you need to be dilligent and careful. An airbag must not be mounted in a  wrong way, it must work when an accident happens.


On one page of SVT can we read "The shortage of skilled industrial workers in Sörmland and Mälardalen can force suppliers to the automotive industry to move production overseas., Says Hans Rainer who is site manager at Automotive Suppliers in Mälardalen." This was written in 2006 and student in industrial programs have not increased. The status has not increased. Admission scores for Industrial Technology program is in the bottom area. http://sverigesradio.se/sida/artikel.aspx?programid=87&artikel=837523

The interest is not so great and it's been moore popular to search on Handicraft program to become a hairdresser.

Thinking of that, these "gurus" who travel the length and breadth of our country and say that we have left the industrial society and entered the knowledge society and to talk about the industry as something that belongs to yesterday, have a great responsibility. They speak so disparagingly of jobs that are important to society. And think about all the others who just repeat this. We had a little guru to visit the school that put knowledge and innovation in contra st to each other. As he said knowledge we can buy cheaply in Asia but we must be innovative in order to compete.
But isn´t it just so that innovative people also tend to be very knowledgeable people.
Why not rather say that as in the second article of Kairos Future, where they promote the idea of "industry .... as the basis for a high-tech knowledge-based society"

The picture shows a water jet cutting machine for cutting plastic, rubber, steel, fiberglass and aluminum discs. A thin beam with high pressure water cutting through the material. The machine must be programmed with the help of a computer. An elegant way to cut various materials with water.

Knowledge Society? Industrial Society? 2013-02-21

Publicerad 2013-02-21 22:30:42 i Allmänt

As long as I've been a teacher, I have been told that we have left the industrial society and live in a knowledge society, a post-industrial society. Most recently, it was a new variation on this theme. A report by Kairos Future on the future role of the teacher says that "society is in a turbulent period of change from industrial society to a global society of thought." Some say that this began to happen in the 70's. The oil crisis in 1973 is seen as a breakpoint.
Seen from a horizon of the GDP, the major changes is that agriculture has been reduced a lot by great efficiency and public sector increased its service share so much. Staffing levels have decreased and increased.
The industry has not changed as mucch as these sectors.
Sure, some industries have moved out, which is part of the explanation for the decline from around 40% to 32%. At the same time China have been heavy industrialised.

Is it right to say that we have left or are leaving the industrial society and entered or are about to enter a knowledge society / global society of thought?

Industrial society, I would say has always been a knowledge society where innovation and research has led to theprogress of development. If we look at the major changes that occurred in the late 1800's when the light bulb and powerstation was invented by Edisson. One of his associates Nikola Tesla invented alternating current and alternating current generator. These two people came to mean much. Edisson is very famous, Tesla is poorly knowwn, but the question that maybe Tesla was the greatest of them. Please read http://computersweden.idg.se/2.2683/1.43947
"Tesla, the man who invented the 1900s" and http://www.tesla.nu/nt_quickfacts.asp

Tesla was a better mathematician than Edison but it is said that they had one thing in common: "The only Tesla and Edison had in common was that they only had a few hours of sleep per day. Often they worked up to three days in a row." When you just need to sleep a few hours per day, you can get further in their field and it has been so with several great scientists.

During the 1900s, this knowledge has been used and the whole world has been illuminated and thye light has totally changed the way people live.

That is what we see in the picture, we can thank Tesla for that. With AC you could locate power stations outside cities. If the world had followed Edison's idea all cities would have had a lot of small power plants with few blocks in between with a major impact on our environment and not as effective. This illuminating of our world is still continuing and is a result of the industrial society.
At the end of the 1900s, we also had a big change in commication with IT-technology plus our dear mobiles beloved over all thingsby our students. But all this is produced by the industrial society.
Industrial society has always been knowledge-based and has always developed the knowledge as the  industrial societies development is based on the research and inventions. We can not distinguish between an industrial society and a knowledge society.
Can we really leave the industrial society that is the basis of our modern civilization?

Think about  the projections of the future. By 2050, it will be another 2 billion people. They need housing, clothes, mobiles, plus various other things and foods produced using industrially produced agricultural machinery. Energy production needs to increase even if we in the West would be forced to lower our standard. More and more people want to have electricity. We have a continuing urbanization of the world's population and which means much tothe cities and its communication needs to expand and occasionally be replaced. Only an industrial society could develop this. It is impossible to leave the industrial society. Should we also start with some space tourism our industries are needed.

In another publication of "Kairos Future" they write about the big changes in the future.

"2013: The year of great change, to think differently or maybe in an opposite way"
"For decades, we have learned that future work is about service and knowledge
and that the industry is a thing of the past. We have also long since relegated the idea that the work runs out and we don´t need to work, such nonsense, we believe in no longer.
History has repeatedly shown how crazy it was. The jobs have not run out. "........

"At the same time the industry goes towards a conceptual renaissance where it is no longer seen as a relict from ancient times, but as the basis for a highly skilled knowledge society.
More and more areas start to yearn for a return of industrialization and David Cameron described this some time ago as one of the biggest challenges.
At the same time politicians talk about reindustrialisation industrial production also move home, albeit on a small scale. Esska has won pacifier manufacture
from Thailand, Stiga pulkproduktionen from China and even Apple has declared that
they'll take home manufacturing to the U.S.. More are in the way.
Finally, what is it we can compete with in the machine age? It is thinking
Perhaps the new black? And if so, are school and college prepared for one
thinking society? Not if you believe one of this fall's debates on DN Debate or
American analysis Academically Adrift. "

How then, will teachers meet this future? It is discussed by Kairos Future and we'll come back to it.

Would probably say that our society has never left the industrial stage, but it has been complemented with IT-technologies and knowledge continues to increase.
And the whole world is still dependent on Tesla's elegant inventions.

Swedes a stone-throwing people once upon a time? 2013-02-18

There were many food riots in the past. When it was bad harvests and grain prices rose while distilleries for strong alcoholic beverages continued like nothing had happened, it was riots and the police tried to stop it but could not always stop these hundreds of people rioting. They threw stones at police, smashed windows on rich man's house and administrative buildings with stones. Many times even the military was called in. The people were protesting that too much grain was spent to make strong alcoholic bewerage and bread prices rose which I understand. People also protested when the rich in society partied with tax money, I understand that too. When this happens today, I also think it is wrong. Or to use tax money to locate courses for municipal employees in foreign countries when there are both facilities and good opportunities at home. Tax money should go to the care, school and welfare at home.

One thing that I noticed in the book was about Karl IV Johan. He was elected as king of Sweden because they needed a strong king in the wartimes as it was then in the early 1800s when the Napoleonic wars raged in Europe.
Unequivocally this new king meant much for Sweden during these troubled times. Read an article in Svenska Dagbladet that the king paid all of Sweden's national debt with his private money. It sounded very good but this is questionable because it was money that came after the sale of the island of Guadeloupe in the Caribbean to France. Sweden got the possession of the island as thanks for the help in the war against Napoleon. Was it Sweden or Karl IV Johan that was entitled to this money?
When Karl IV Johan had reigned in Sverigre for 25 years, this would be celebrated with a big party 1843. The city's 500 most important residents were invited. Through some papers it emerged that the party would be paid by taxmoney. Many felt that the city's money that paid for poor relief should not be used for a royal party. Protesters marched through the streets and started throwing stones at the windows of the houses, some 30 houses got broken windows and the police lost control of the demonstrations. The crowd moved to Stockholms theater and inside there was a gala performance. The theater was taken and both actor and spectators had to flee head over heels.

A recensent writes about the book "Surprisingly very familiar from Sweden and the world today and yesterday: Masked protesters, throwing stones, hunger riots, bombings, racism, letter bombs, anthrax attacks, muslim terrorism, xenophobia, anti-racism, football hooligans, assaulted journalists, potatoes rescues the poor, religious extreme sects, opposition in mental hospitals, protests against food used for other than food production (as spirits, now biofuels).

Today, we also have stone throwing people but now it's not so much the Swedes as immigrant youths throwing stones at police, firefighters and paramedics. Particularly well known is this from Malmö and we've all read about it and seen it on TV. There is no question of any hunger riots earlier. A derogatory image in an instagram was what started it all in Gothenburg last autum.

Stones to rescue personnel in Rosengård are familiar to all.

Fredrik Ekelund, a wellknown writer from Malmö, has written about this. Read what he wrote about stone-throwing in Rosengård riots when it happened there. It went on for several days and the police failed to stop it, but as through a magic stonethrowing were stopped by leading muslism men / gang leader.

Fredrik Ekelund writes "When Besam Mahmoud, self-appointed spokesman for the Islamic Cultural Society in Rosengård, speaks of" discrimination "and" us Muslims "should be clear about who he is and what his organization wants. In his world, integration is not a good thing in itself . It is the enclave and the self-willed alienation that is the case and the unwillingness to integrate as the Sweden Democrats. An interesting thing here is that the representatives of the Islamic Cultural Society was low at the start of the riots. But the same day, day five or six, they told the parents of the association to go out and put a stop to it all, then everything stopped up, as of a given command. The question to ask is, of course, why did not Besam Mahmoud and other leaders that had responsibility stop it the very first night? "

Some Muslim groups express clearly, we do not want to be integrated into the Swedish society. It is haram, a sin.
The following, you can read "The integration of Islam and Muslims in non-Islamic society is haraam and is at odds with the message of Islam because integration means sacrificing some elements of Islam to it, and the Muslims will be part of whole, namely the Swedish society and Sweden., the big question that remains unanswered is what parts do we need to give up? Concrete examples are never given, and partly because this false thought's proponents do not have a crystal clear idea of its own message, and partly by the fear for the overwhelming and uncontrollable rage these examples will awaken the Muslims, who can not, or may not like such a large-scale corruption of Islam.

Mona Sahlin said once ('she said it several times) "We have failed with our integration policy" - TV1 September 28, 2001 http://sv.metapedia.org/w/Mona_Sahlin
The thing is that it is not easy to integrate persons for whom it is haram / sin to become integrated. They want their own Muslim community, preferably with Sharia law. Luckily not all muslims are like that.

What will we finally say about the stone-throwing Swedes. Mats Adolfsson concludes the book like this and thinks of the development since the 1930s: "A new self-image was formed. Rear tinted an image of an eternally peaceful, kind, neutral and sometimes wimpy Swedish, who would rather tie your fist in your pocket than protesting openly and who trust the authorities. Engelbrecht, Dacke and 1743 years of rebellious Dalesmen probably would not have recognized themselves in the description.
Will it be the same trend with the stone throwers alive today?
