This research follows the team’s groundbreaking first step in 2002 at Durham, when they managed to create a basic computer operation or ‘logic gate’ using a magnetic microchip. Since 2002 the team has created a number of further ‘logic gates’ and created interconnecting structures using magnetic ‘nanowires ‘, which can now reproduce the logic functions of a conventional computer empowered by semiconductor electronics. Dr Del Atkinson of Durham University comments on this success are: “This new technology offers a number of advantages over conventional computers. Electronic microchips generate a lot of heat, which creates the need for fans in PC units, whereas these magnetic microchips do not generate this heat. . The magnetic microchips that have been created are also simpler and potentially cheaper to produce than the electronic chips. They are economical insofar as they use simple metals layers.This would also imply that the computers being economical would become still more disposable. “ This means that they could be used for cheap and therefore disposable simple computers in the future., “ Dr. Atkinson further commented: “These developments are important and exciting and while there is still some way to go, the potential is there to create a whole new technology based on magnetism rather than electricity.”This use of magnetism, rather than that of electricity has potential of being exploited further .The team is working in the rapidly growing field of nanotechnology, harnessing the magnetic properties of electrons, rather than their electrical charge on which conventional electronics is based. Nanotechnology involves working with materials at an extremely microscopic level. A nanometre is one thousand millionth of a metre – about the width of five atoms.This harnessing the capability of magnetic properties of electrons could mean a sea-change in the field of electronics.by Dr. Bikram Lamba, Copyright 2005 PhysOrg.com Dr. Bikram Lamba, an international management consultant, is Chairman & Managing Director of Tormacon Limited- a multi-disciplinary consultancy organization.

Researchers claim a third of dinosaurs might never have existed

first_img Explore further Jack Horner, of Montana State University, said in a new documentary to be aired on the National Geographic channel, that one example was the Nanotyrannus, which was identified as a separate species but which may in fact be a juvenile Tyrannosaurus Rex, whose skull changed dramatically as it matured, becoming much less elongated. This was suggested after a dinosaur mid-way between the size of a Nanotyrannus and Tyrannosaurus Rex was discovered. According to Horner, Nanotyrannus, which had 17 teeth in the lower jaw, was in fact a juvenile T. Rex, which had 12 lower-jaw teeth. The newly discovered dinosaur had 14 teeth in the lower jaw. Horner suggests that as the Tyrannosaurus Rex grew, it lost its small, blade-like teeth for larger bone-crushers.The researchers also studied late Cretaceous fossils of Triceratops found in the Hell Creek formation in eastern Montana. These dinosaurs had died at various ages, and their fossils revealed a number of changes as the animals grew. The skulls revealed the juveniles’ horns curved backwards, while the adults’ horns pointed forwards, while the bones around the frill flattened and lengthened as the dinosaur matured.Another researcher, Mark Goodwin, of the University of California in Berkeley, explained that they had been able to obtain a better growth series than had been available before, and this enabled them to document the changes occurring during the growth of the animals. Big changes in the body from infancy to adulthood may have been occurred for similar reasons to changes that occur in species today that ensure members of a species recognize each other and can distinguish between adults and juveniles needing protection.Not all paleontologists are convinced by the study. Paleontologist Hans-Dieter Sues, of the National Museum of Natural History in Washington DC agreed that some dinosaurs identified as separate species may turn out to be juveniles, since many vertebrates change in appearance as they mature. But the conclusions of the study are controversial and the claim that about a third have been misidentified is exaggerated, according to Sues. Testing the hypotheses is also difficult because there are not enough available fossils.The research is featured in a National Geographic documentary entitled “Dinosaurs Decoded”.© 2009 PhysOrg.com This document is subject to copyright.

Hibernators live longer mainly because they escape predators

first_img Researcher Christopher Turbill of the Research Institute for Wildlife Ecology in Vienna, said that when animals hibernate they slow their metabolism and thus vastly reduce the energy required for their survival. They also tend to find a safe place in which to hibernate, which means they are less likely to die from predation while hibernating, and the research team believes this is the key to their longevity.Previous research also suggested that hibernating animals tended to have longer lives, but this was thought to be because they avoid the harsh winter temperatures and the competition for dwindling food supplies.Hibernation allows the animals to have around a 15 percent higher survival rate but they have fewer offspring each year than non-hibernating animals. In rodents for example, a non-hibernating species such as a rat weighing around 100 grams has up to 14 offspring a year, has a 17 percent chance of surviving the year, and its maximum lifespan is about 3.9 years. A hibernating rodent of the same size has only about eight offspring a year, but has a 50 percent chance of surviving and a maximum lifespan of 5.6 years.The research, which was based on analyzing previous studies of hibernation, along with new data on the edible dormouse (Glis glis), also suggested that hibernation could have been involved in the evolution of slower life-cycles, since hibernating animals tend to mature later than non-hibernating species with shorter lifespans. Co-author of the paper, Claudia Bieber of the University of Veterinary Medicine in Vienna, said scientists had previously thought hibernation posed a challenge for animals, but their research had shown the animals survive exceptionally well and also have a better chance of surviving the active season than non-hibernating animals. This is particularly true of small species (under 1.5 kg), such as the edible dormouse, which spends half the year in hibernation.The paper was published this week in the Proceedings of the Royal Society B: Biological Sciences.

Rational design can improve hydrogen fuel cell efficiency

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Explore further The researchers, Sergey Stolbov and Marisol Alcántara Ortigoza from the University of Central Florida, have published their study on the new efficient electrocatalysts in a recent issue of The Journal of Physical Chemistry Letters. Currently, most hydrogen fuel cells use catalysts made of platinum, a rare and expensive material. Finding an alternative to platinum is challenging because few materials can withstand exposure to the fuel cells’ highly acidic solvents, which dissolve most transition metals. Only four elements – platinum, iridium, gold, and palladium – can resist corrosion, but none is ideal. Platinum and iridium are rare and expensive, while gold and palladium do not perform well due to low redox reactivity.In this study, Stolbov and Alcántara Ortigoza focused on improving the redox reactivity of gold and palladium through the use of in-depth modeling.“We have proposed a new concept for rational design of stable and highly active electrocatalysts for hydrogen fuel cells,” Stolbov told PhysOrg.com. “We believe that our approach is much more efficient than the widely used combinatorial screening of dozens of materials. Our first attempt to apply this approach has resulted in the prediction of two cost-effective and highly active catalysts for hydrogen fuel cells, a clean and renewable energy source.”The researchers explained that previous attempts at searching for better catalyst designs have used trial and error, although some studies have used computational searches. By using a rational design approach, the researchers could predict the performance of different tri-metallic catalyst designs using previous knowledge, such as the relationship between the composition/morphology and electronic structure of the catalyst surface, its stability, the thermodynamics that the reaction intermediates, and the reaction kinetics.This method led the researchers to a new design consisting of a three-layered sandwich-like structure. In this design, redox reactions take place on the first layer, while the second layer can tune the electronic structure of the first layer, and the third layer serves as the substrate. As an example, the researchers used gold as the first layer, then chose ruthenium as the second layer due to its ability to tune the gold layer to increase its redox reactivity. When using palladium as the first layer, their method predicted iron as a good tuning material. The ruthenium and iron do not have to come in contact with the acidic solvent, yet still contribute to the catalyst’s efficiency. In both cases, the researchers used tungsten as the substrate, which also contributed to performance in a twice-removed way by straining the middle layer.The researchers’ calculations showed that both the gold-based and palladium-based sandwich-like catalysts were more highly reactive and therefore more efficient than today’s best platinum-based catalysts. How much more efficient can only be accurately determined by experiments, which the researchers hope will be performed soon.“We are looking forward to experimental confirmation of our findings,” Stolbov said. “We are contacting experimentalists who are interested in these materials. Using our approach, we have already selected a number of sandwich-like structures as promising electrocatalysts in an attempt to find even better catalysts. In order to test this rational selection, we will perform computational studies of the electronic structure and stability of the chosen systems and the thermodynamic properties of the reaction intermediates on the catalyst surfaces. Then again, we will ask experimentalists for testing the most promising systems. Since our approach can be extended to design the stable structures tuned for reactions in heterogeneous catalysts, we will focus on this subject next.” (PhysOrg.com) — Hydrogen fuel cells, in which the chemical energy of hydrogen is converted into electricity, offer the potential for a wide variety of applications, especially in transportation and power generation. Although hydrogen fuel cells are currently used on a small scale, making them commercially available for large-scale use requires improvements in two key areas: efficiency and cost-effectiveness. In a new study, scientists have designed tri-metallic electrocatalysts for hydrogen fuel cells that theoretically improve in both areas, outperforming the best platinum-based catalysts to date.

Researchers find antioxidants can dispel static electricity

first_imgCredit: Chris Darling via Wikipedia. More information: Control of Surface Charges by Radicals as a Principle of Antistatic Polymers Protecting Electronic Circuitry, Science 20 September 2013: Vol. 341 no. 6152 pp. 1368-1371 DOI: 10.1126/science.1241326AbstractEven minute quantities of electric charge accumulating on polymer surfaces can cause shocks, explosions, and multibillion-dollar losses to electronic circuitry. This paper demonstrates that to remove static electricity, it is not at all necessary to “target” the charges themselves. Instead, the way to discharge a polymer is to remove radicals from its surface. These radicals colocalize with and stabilize the charges; when they are scavenged, the surfaces discharge rapidly. This radical-charge interplay allows for controlling static electricity by doping common polymers with small amounts of radical-scavenging molecules, including the familiar vitamin E. The effectiveness of this approach is demonstrated by rendering common polymers dust-mitigating and also by using them as coatings that prevent the failure of electronic circuitry. Despite centuries of observation and work, scientists don’t really understand how static electricity works, which is a problem because our evolution has led us to a heavy reliance on electronic devices—one tiny spark can render them useless. Sparks can also set off explosions when they occur around gasses and flammable liquids, thus, research continues to find a way to stop static electricity from building up, or from being released in destructive sparks. In this new effort, the research team from Northwestern appears to have found a way to allow polymers to discharge harmlessly using nothing but antioxidant coatings.Scientists don’t really understand how it is that friction causes static electricity to build up, but one thing is clear, most have been overlooking the relationship between charge buildup and free radicals that also exist on a surface. To learn more, the researchers caused static to build up on several types of polymers then took a closer look using atomic force microscopy (a type of microscopy that can map the location of molecules). In so doing, they noticed that static charge builds up in clumps, and it’s the clumps that eventually provide a channel for the release of the charge. More importantly, they also noticed that the clumps also had free radicals mixed in with them—a phenomenon that made the researchers wonder if simply applying an antioxidant might cause the release of both the free radicals and the charge in a slow safe manner.To find out they created several batches of coatings with vitamin E and other antioxidants as a base and applied them to several types of polymers then applied a charge in two different ways: directly through contact with another material, or indirectly using an electrostatic charge. They found the coatings they developed worked to dispel static electricity buildup no matter how it got there—and were able to witness their success as the polymers no longer allowed dust to collect on their surfaces.The research team has applied for a patent on their coatings, but if their findings can be replicated by other scientists, it will mean the end of run-around solutions to static buildup and the damage that it can cause. Journal information: Science Northwestern research team turns theory of static electricity on its head (Phys.org) —A team of researchers at Northwestern University has found that applying antioxidants such as vitamin E to polymers can cause static charge buildup to disperse without an associated shock. In their paper published in the journal Science, the researchers describe their study of static electricity and how they found a previously unknown relationship between charges and free radicals.center_img Explore further Citation: Researchers find antioxidants can dispel static electricity (2013, September 20) retrieved 18 August 2019 from https://phys.org/news/2013-09-antioxidants-dispel-static-electricity.html © 2013 Phys.org This document is subject to copyright.

Higher divorce risk when mates are plentiful? Evidence from Denmark, Biology Letters (2018). DOI: 10.1098/rsbl.2018.0475 There are, of course, a lot of factors that contribute to the success of a marriage. In this new effort, the researchers suggest one might be the degree of availability of other options. They carried out a study to learn more about factors that might contribute to the success or failure of marriages. It involved gaining access to and analyzing data on people living in Denmark over the years 1981 to 2002. They narrowed their focus to married heterosexual males and females who held jobs during that time span. They compared divorce rates between people in different occupations.The researchers found a trend—people who worked with a high ratio of co-workers of the opposite gender had higher divorce rates than those who did not. They noted the increase was most pronounced with men, and in particular, men with more education. Interestingly, for women with more education, there was no increase. The research did not uncover reasons for these trends, but the researchers offer some possibilities—such as men being more attracted to people with similar education and job interests. They note also that simply being around more women likely gave them more opportunities to meet a more suitable mate. The researchers also found that age at marriage appeared to play a role in the likelihood of divorce as well—those getting married younger were more likely to divorce than those waiting till after age 40. Also, living in the city had an apparent impact—those who lived outside of Copenhagen were less likely to get divorced than those who lived in the city. Also, more education in general tended to result in lower divorce rates. © 2018 Phys.orgcenter_img Journal information: Biology Letters A pair of researchers at Stockholm University has found that people who have a lot of co-workers of the opposite gender might have a higher risk of divorce.

The artist, using his internal logic, places one piece of drawing or painting, which could be a series of portraits, nudes or even animal heads, in relationship with the other in the ensemble and the cohesiveness looks so strong that taking out one of them would end up in totally collapsing the work of art.  But at the same time, if they are independently exhibited, without showing the possibility of them being together in a collage, they assume the nature of autonomous works of art, not even once betraying their closer affinities with the work of art seen/displayed next to it. Where: Art Indus, Race Course RoadWhen: April 24 to May 7 Timing: 11 am till 7 pmlast_img read more

Amid fears of oil spill from MV SSL Kolkata Forest Dept looks

Cut 71minute sitting time in office and live longer

first_imgWorkers please take note! Taking frequent breaks to reduce sitting time at workplace can help you cut extra body fat, thus lowering the risk of heart disease, diabetes and early death.The results which were followed up for three months showed a reduction of 0.61 per cent in body fat in study participants. This was a result of 71-minute shorter sitting time per day during working hours after one month.“A reduction in sitting time by 71 minutes per day could have positive effect in the long run as this could be associated with reduced risk of heart diseases, diabetes and all-cause mortality, especially among those who are inactive,” said professor Janne Tolstrup from National Institute of Public Health, Denmark.

Keeping theatre alive

first_imgMovies gets fame, television gets wealth, but it is theatre that gives the greatest satisfaction, say most theatre veterans. Om Puri who passed away and had been a veteran of the National School of Drama often said he never got from cinema the joy he got from acting on stage in the presence of a receptive audience. It is that rapport with the audience that keeps theatre alive.Delhi’s Tadpole Repertory and Tokyo based theatre collective Hanchu-Yuei have collaborated to add new flavor to modern theatre with “This will only take several Minutes” at OddBird Theatre and Foundation, New Delhi on February 2 and 3 – presented by The Japan Foundation, New Delhi. Also Read – Add new books to your shelf”This will be the opening performance for the Japan Foundation New Delhi in 2017, The Year of Japan-India Friendly Exchanges, and will be a representation of the great relationship between the two countries”, says Misako Futsuki, Director of Art & Cultural Exchange at the Foundation.’This Will Only Take Several Minutes’ is set in a city not far from yours. Six strangers confront themselves and each other, seeking out their place and purpose. They grapple with hunger and sickness, love and solitude, through their shadowy pasts and the foggy present. Also Read – Over 2 hours screen time daily will make your kids impulsive In all of this there is but one certainty – that they cannot escape this place and must try anything they can to bear it.Tadpole Repertory is a theatre collective of actors, writers, musicians and designers. The group is dedicated to presenting original written and devised performances on subjects that are relevant and compelling to audiences today. The approach to stagecraft seeks to rise above the limitations of independent theatre in the country, and to push its boundaries and conventions. Tadpole’s productions include Taramandal (2010), winner of the Hindu MetroPlus Play-writer Award in 2010; a critically acclaimed production of William Shakespeare’s The Winter’s Tale, A Brief History of the Pantomimes and NDLS, a variety sketch show about life in Delhi. Futsuki added, “It’s been a great pleasure for me to organize this project. As a director of Arts & Cultural Exchange Programme at the Japan Foundation, New Delhi, I strongly feel the necessity of cultural projects in more mutual ways to learn from each other, not just showcase from one side only in this emerging global society. The play is the result of a three-year journey from Tadpole founder Neel Chaudhuri’s first encounter with Suguru’s practice in Japan in 2014.”Collaboration sounds beautiful, but not always so beautiful. There are some difficulties when different cultures meet. However, as the two theatre groups do in this project, if you try to understand and learn from each other, there will always be something wonderful there,” Futsuki said.Playwright and Director, Suguru Yamamoto has attracted attention in Japan and Asia for his unique style of staging that combines projected text, photography, video, color, light, and shadow with performers, as well as his scripts that question our ethics. His play “Girl X” won Best Play and Best Original Script award at the Bangkok Theatre Festival in 2014. Another play, “I can’t die without being born”, was shortlisted for the 59th Kishida Kunio Drama Award in 2015.last_img read more

How healthy is your Pasta

first_imgToday being World Health Day, let’s talk about something healthy and shove aside our regular favourites from the diet chart. For foodies who love to gorge into fried stuff and cheese, it’s time that you pull up your socks and head straight to a healthier path by ditching them. Among all other lip-smacking dishes, pasta finds a place in everybody’s list of favourite items. But are you sure that you are consuming the right pasta? “Most pastas available in Indian market are made of refined flour, and are rich in carbohydrates but no vitamins, minerals and fibre. Consuming large amount of such food can be harmful to health,” warns Dr Reeti Kapoor, Senior Manager-Dietetics, Venkateshwar Hospital. “Foods with empty carbs i.e only calories without any other nutritional benefits contribute to weight gain without having other health benefits. However, this doesn’t mean that pasta is inherently a bad food. If you love pasta, look for varieties that are made of whole grain which is rich in fibre and vitamins as well apart from carbohydrates,” adds Dr Kapoor. Also Read – Add new books to your shelfDr Himanshi Sharma, Sr Dietician, Indian Spinal Injuries Centre in the Capital says, “Eat pasta as a base for a healthy snack rich in veggies, lean protein and healthy fats. Choose red sauce instead of white sauce and add a lot of vegetables. To make a healthy dish, one can add herbs, lentils and healthy nuts (almonds and walnut). As of very high carbohydrates content which may cause fluctuations in blood sugar levels.”People who are allergic to gluten must stay away from pasta, since it may affect them with giddiness, and abdominal bloating. There are various types of pasta in terms of ingredients. A 100 per cent whole-grain pasta includes all the layers of the wheat kernel. Since nothing is removed during processing, whole-grain pasta contains more natural fibre and micronutrients than white pasta. They tend to have a chewier texture and “grainier” taste as compared to regular pasta. Blends like whole-wheat-and-white are perfect for families who are trying to make the switch to whole-grain but want to gradually adjust to its taste and texture.

Even kids experience body image issues

first_imgChildren as young as eight may be vulnerable to poor body image as hormone levels rise with the onset of puberty, a study has found.The study based on data from more than 1,100 eight- to nine-year-olds indicates a need for strategies in schools and at home to help children maintain a positive body image prior to the onset of puberty.The research explored a link between hormones and body satisfaction in young pre-pubescent children for the first time, said Elizabeth Hughes, from University of Melbourne in Australia. Also Read – Add new books to your shelfPublished in the Journal of Adolescent Health, the study clearly indicated that there was a need for strategies in schools and at home to help children maintain a positive body image prior to the onset of puberty.Researchers of the study found that girls tended to be more dissatisfied with their bodies than boys, but boys with higher hormone levels also felt unhappy with their physical shape.’What we have learnt is that pre-pubescent children, as young as eight and nine, are vulnerable to poor body image and the dissatisfaction does appear to be linked to hormone levels associated with the onset of puberty,’ Hughes said. Also Read – Over 2 hours screen time daily will make your kids impulsive’Basically the higher the level of hormones, the more unhappy the children were with their body size; however children with heightened levels of hormones also tend to be taller and heavier than their peers, and this could be the cause of their poor body image,’ she said.The research might lead to a discussion about strategies and programs that could help children maintain a positive body image prior to the onset of puberty, researchers said.’It may be that children who are taller, heavier and more physically mature, feel more conspicuous amongst their peers,’ Hughes said. ‘There may be a need for community and school programs that help young people learn about what underpins good self-esteem, because self-esteem is not solely invested in physical appearance,’ she said.Body dissatisfaction was measured using a tool called the Kids’ Eating Disorder scale (KEDS) body image silhouettes.This is comprised of eight illustrated silhouettes of children ranging from very thin to very obese.There are separate sets for females and males.The child is first asked to select the silhouette that most looks like them now (self-rating), and then asked to select the silhouette they would most like to look like (ideal rating).Each silhouette is scored and by subtracting the ideal from the self-rating children are allocated either a positive or negative body satisfaction score.Adrenal androgens, which are naturally-occurring steroid hormones such as DHEA and testosterone, were measured through saliva.last_img read more

The Sergeant who was promoted to King of Sweden

first_imgDuring the French Revolution and later the Napoleonic Wars, the aristocracy of France was decimated and their role in French society was left in a vacuum ― royal sympathizers, nobles, military officers, clergy, and other aristocrats either fled or faced the guillotine. On the other hand, the revolution enabled many members of the bourgeoisie to rise through ranks and take on functions previously reserved for people of noble descent. It was a time of great turmoil, in which a new ruthless meritocracy made way for those who dared.“The Storming of the Bastille” – visible in the center is the arrest of Bernard René Jourdan, m de Launay (1740-1789).As Napoleon began his conquest of Europe, a number of non-commissioned officers managed to rise through the ranks and reach lofty positions, some of them even receiving the distinction of being Marshals of France.One such story even led a man to become the King of Sweden and form a dynasty which currently rules this Scandinavian monarchy. His name ― at least before he became royalty ― was Jean Bernadotte.Charles XIV John of Sweden & Charles III John of Norway.Bernadotte was born in Pau, in the south of France, to a middle-class family. After a period of education and apprenticeship as an assistant for a local attorney, Jean joined the military in 1780. By the time the revolution came knocking in 1789, he held the rank of sergeant.What followed was a quick rise through the military hierarchy during the wars which shook France immediately after the revolution and gave birth to its future Emperor: Napoleon Bonaparte.In 1794, Bernadotte was promoted to divisional general after his division under General Jean-Baptiste Jourdan defeated the coalition of four European powers at Fleurus, during the Flanders campaign.Napoleon Bonaparte, aged 23, lieutenant-colonel of a battalion of Corsican Republican volunteers. Portrait by Henri Félix Emmanuel Philippoteaux.Now commanding a contingent of troops he once again earned praise and promotion during the Battle of Theiningen in 1796 and joined the conquest in Italy during the following year. During this time Bernadotte met with Napoleon who rewarded him with yet another promotion ― the former private in the French Royal Army was now appointed commander of an entire division.Still, despite Napoleon’s great success in Europe, France was governed by a special five-man committee called the Directory. In order to seize power, Napoleon had to conduct a coup d’etat, which was exactly what he did in 1799.Bernadotte’s birth house in Pau, France.In the meantime, Jean Bernadotte became a significant player in the constellation of newly-formed figures of influence. He married the sister-in-law of Napoleon’s older brother, Joseph, which elevated him further into the elite.At the time of the proclamation of the French Empire in 1804, Bernadotte was among Napoleon’s most trusted officers and was named one of the original eighteen Marshals of the Empire. But apart from being a clever socialite, this cunning Frenchman continued to amaze his leader on the battlefield. His contributions to Napoleon’s victory at Austerlitz earned him a noble title of Prince of Pontecorvo province in Italy.Bernadotte, as Marshal of the French Empire.What followed was a series of almost mythical triumphs by Bernadotte on the field of battle. On one occasion, after capturing defeated Swedish troops at Lübeck, the Marshall let them go home. This gesture earned him praise in Sweden ― like an omen for things to come.Following the turmoil brought about by the French Revolution, Sweden and Russia entered a short conflict regarding Finland in 1808, which was at that time under Swedish rule. The result was the formation of the Grand Duchy of Finland, under the patronage of the Russian Empire.Statue in Norrköping erected in 1846. Photo byThuresson CC BY-SA 2.0The defeat caused outrage in Sweden, and King Gustav IV Adolf was deposed by his uncle, Charles XIII. However, the new king suffered from premature senility and a lack of heirs. One of his children was stillborn, while the other died within the first week of his life. Thus, the Swedish parliament ― Riksdag of the Estates ― took matters into their own hands.8 Words you will NEVER hear the Royal Family sayThey appointed Christian August of Augustenborg, Prince of Denmark, as their presumptive heir to the throne. However, only one year after being appointed, the Prince suffered a stroke from which he never recovered.Meanwhile, the Napoleonic conquest had left Europe shaken. The Emperor appointed his brothers and trusted generals as heads of client kingdoms across Europe in an attempt to unify the continent under his rule.Charles John, born Jean Bernadotte, King of Sweden and Norway 1818-1844. Portrait by Fredric Westin.The Swedish Parliament agreed on letting Napoleon suggest someone suitable to take up the role of king of Sweden. This was how Jean Bernadotte, an attorney’s assistant and a professional soldier, entered the royal Scandinavian bloodline.The Prince of Pontecorvo adopted a new name ― Charles XIV John of Sweden.The coronation of Charles XIV John as king of Norway performed in the Nidaros Cathedral of Trondheim in 1818.He de facto ruled the country as regent from 1810 to 1818, during which time the old king Charles was still nominally in power. After his death in 1818, Bernadotte became the King of Sweden and the King of Norway, as the two countries were in a form of a union at the time.He would hold on to this title until his death in 1844, after 26 years of peaceful reign.Bernadotte FamilyThe new king proved more than capable of balancing his power within the restraints held by the Parliament. His rule in the post-Napoleonic period is characterized by a wise decision to maintain good relations with the Great Powers such as England and Russia while ending the traditional expansionist policy that had often led Sweden into costly wars and disastrous defeats.Bernadotte’s approach concerning the foreign policy of the country is today considered as being the forerunner of Sweden’s neutrality, while his domestic policy focused on economy and investments, providing a period of great prosperity for the nation.Carl XVI Gustaf of Sweden in 2017.In addition, being a former soldier earned him great respect from influential figures within the army who admired his peacemaking skills and readiness for war.Read another story from us: Grace Kelly’s family had to pay Prince Rainier III of Monaco a dowry of $2 million for their marriage to happenThe House of Bernadotte continues to be the ruling dynasty in Sweden to this day, with the current king, Carl XVI Gustaf of Sweden, being a descendant of the famous Marshal of France, Jean Bernadotte.Nikola Budanovic is a freelance journalist who has worked for various media outlets such as Vice, War History Online, The Vintage News, and Taste of Cinema.

The Story of Cinderella Goes Back 2000 Years

first_imgFor many people, Cinderella immediately brings to mind the images created by Disney back in 1950 – the fairy Godmother, the sweeping blue ball gown, the glass slipper, and the singing mice. The story, as told in the animated film, is a pretty watered-down interpretation. Cinderella’s story is much older than Disney’s adaptation. In fact, it can be traced back to stories that date back as far as 2,000 years ago, according to Vox.Cinderella Fleeing the Ball by Anne Anderson.The story of Cinderella, at its most basic, is of overcoming oppression and crossing class lines. The first iteration of the story can be traced to Greece, during the sixth century B.C. In the Greek version of the tale, a courtesan named Rhodopis has her shoe carried away by an eagle.The eagle takes it across the Mediterranean and drops it in the lap of an Egyptian king. The king goes looking for the shoe’s owner, and eventually finds Rhodopis and marries her, lifting her from her previous station in life and making her a queen.Pair of ancient leather sandals from Egypt.Another very old version of the story exists in China and is the tale of Ye Xian. According to Ancient Origins, she was the motherless daughter of a cave-dwelling chieftain. There is a very similar cast of characters to the Cinderella myth we recognize today, including an evil stepmother and unkind step-sister. In place of a fairy godmother, Ye Xian has the magical bones of a fish, which grants her wishes.The story of Ye Xian reflected the admiration for small feet in ancient China. Foot binding later became a common practice to prevent feet from growing.When her father dies, she becomes the servant to her step-family who wish to degrade her and keep her from outshining her stepsister, Jun-Li, who is significantly less attractive than Ye Xian. When her family goes to a festival celebrating the New Year, she is left behind.With help from the magic bones, she goes to the festival wearing a beautiful gown and golden shoes resembling fish scales.She is well received by everyone at the party, but is afraid of being recognized by her family and flees, leaving behind a shoe.Cinderella shoe.The shoe trades hands several times, eventually coming into the hands of a king. The king is fascinated with the shoe’s very small size and has it put on display in a pavilion. Ye Xian eventually makes her way to the pavilion, convinces the king to let her try on the shoe, and the usual happy ending occurs.Cendrillon story by Charles Perrault.Across Europe, there are more than 500 versions of this same basic theme. Among the most famous are the tales of Aschenputtel, written down by the Grimm brothers, and Giambattista Basile’s La Gatta Cenenterolla.While both of these are remarkably more violent than our beloved Disney version, they are based on older — and darker — folk tales. Murder, mutilation, cannibalism, and incest all feature in these tales from around the globe.Charles Robinson illustrated Cinderella in the kitchen (1900), from “Tales of Passed Times” with stories by Charles Perrault.The version of the story most of us know best, the one that would define Cinderella for the next 400 years, originated in France in the 17th century and was called Cendrillon. Charles Perrault’s version of the fairy tale, published in 1697, is the first to include the pumpkin, fairy godmother, and a few friendly animals who help poor Cendrillon find her prince.All the versions of this very old story have some themes in common. The first is women of beauty suffering in privation, poverty, and/or the lower classes and being raised into the realm of royalty and, usually, love.Oliver Herford illustrated Cinderella with the Fairy Godmother, inspired by Perrault’s version.Another is that all versions of the story reflect the social and political powerlessness of women relative to men during much of history. Cinderella is largely a passive figure. All the things that prove to be her salvation come from sources other than herself.In the modern versions of the story, she is portrayed as being the privileged child of a wealthy man until her father’s death strips away her status. Her status and security are regained only through the prince.Finally, the story can also be interpreted as a morality tale promoting women staying within their proper roles in society in that the heroine’s beauty can symbolize virtue and purity, which are rewarded, whereas the figures of the step-family who embody meanness and spite are generally portrayed as being ugly, and in many versions of the tale come to bad ends.Read another story from us: The true story of Pocahontas is sadder and less romantic than the enduring mythsNo matter which of these interpretations you choose, though, modern society’s romanticization of the story is probably an undesirable thing to push on to young girls.last_img read more

LeBron CP3 D Wade and Melo call for an end to police

first_imgIn an era where athletes rarely speak out, other than a comment to the TMZ cameras, a group of NBA superstars used the ESPY’s, last night, as a platform to speak out about the recent police shootings involving Alton Sterling and Philando Castile.LeBron James, Carmelo Anthony, Chris Paul and Dwyane Wade gave a moving statement about the recent controversial shootings and pledged to use their platform and influence to try to affect positive change. Wade called for people on all sides of the issue to take accountability.“The racial profiling has to stop. The shoot to kill mentality has to stop. Not seeing the value of black and brown bodies has to stop. But also, the retaliation has to stop. The endless gun violence in the places like Chicago, Dallas, and not to mention Orlando, has to stop. Enough.”The issue of police violence is an extremely polarizing issue, but it’s refreshing to see superstars using their platform to speak out on more than when their new sneaker comes out.The #ESPYs open with a powerful Black Lives Matter tribute: “We all have to do better” https://t.co/BQovoVN4pk https://t.co/GUuHW7ZwcM— Hollywood Reporter (@THR) July 14, 2016last_img read more
