Researchers Have Accidentally Made Batteries That Could Last 400 Times Longer

By
Elizabeth Williams

Science never ceases to amaze us. With each passing day, there are discoveries that hold the potential to change the way we live and think. Some of these discoveries are the result of years of research, others come about completely by accident. Whichever the case, these innovations are a great leap towards a better future for all mankind.

Researchers from the University of California-Irvine have managed to develop a battery that could last up to 400 times longer than any other battery available on the market.

The weird thing is: the discovery was completely accidental. The researchers were trying to find an alternative to lithium, whose liquid state helps conduct charge but is, at the same time, highly combustible and sensitive to temperature.

Their nanowire-based battery material can be recharged hundreds of thousands of times, which means we are one step closer to having batteries that would never require replacement. Awsome, right?

By using gold nanowires to store electricity, the scientists found that their newly developed system could cycle through 200,000 recharges without any significant corrosion or decline. These results are jaw-dropping even thought the research is still in its early stages and a lot more needs to be done.

What is most astounding, is the fact that they bassically stumbled upon this amazing discovery. What they wanted to make in the first place was a solid-state battery that uses electrolyte gel instead of liquid to help it hold charge.

According to study leader, UCI doctoral candidate Mya Le Thai, they coated a gold nanowire in a manganese dioxide shell and encased the assembly in an electrolyte made of a Plexiglas-like gel.

“Mya was playing around, and she coated this whole thing with a very thin gel layer and started to cycle it,” said Penner, chair of UCI’s chemistry department.

“She discovered that just by using this gel, she could cycle it hundreds of thousands of times without losing any capacity.”

“That was crazy,” he added, “because these things typically die in dramatic fashion after 5,000 or 6,000 or 7,000 cycles at most.”

“The coated electrode holds its shape much better, making it a more reliable option,” Thai said.

“This research proves that a nanowire-based battery electrode can have a long lifetime and that we can make these kinds of batteries a reality.” 

In a nutshell, this new design allowed batteries to have 97% capacity after 1.000 cycles of charging and discharging. However, due to the high price of gold, the scientists state that nickel could be the perfect substitute for gold for mass production.

The discovery could lead to the development of batteries that could last forever so you never have to worry about recharging your laptops, phones and anything else that requires batteries to run.

According to the official announcement, the study was conducted in coordination with the Nanostructures for Electrical Energy Storage Energy Frontier Research Center at the University of Maryland, with funding from the Basic Energy Sciences division of the U.S. Department of Energy.

10 Things You Didn’t Know About Nikola Tesla

By
Elizabeth Williams

Nikola Tesla was widely known as the father of the modern age. He is most famous for his  inventions of the alternating current (AC), wireless technology, television and the radio, and robotics, among other important things.

Tesla was born to a Serbian family in Yugoslavia, in the now Croatian village of Smiljan. He moved to the United States at the age of 28 with only a few pennies in his pockets and managed to become one of the most influential scientists in the world.

Tesla managed to create a lot of inventions and he invested the money he earned from those inventions in creating new ones. He didn’t really care much about money, he lived in hotels in New York and he died poor and alone. He once said that he didn’t have anything against people claiming his inventions as their own as long as they served for the good of humanity.

There are a lot of stories surrounding his life and work, but these 10 things are something you probably haven’t heard of before.

  1. Tesla cared a lot about the environment

Tesla was concerned about people’s dependency on natural resources that were not renewable, such as coal, oil and the most dangerous one – nuclear power. He saw the destructiveness in the process as not only being unsustainable resource-wise, but also destructive to the environment. That was the main reason why he was trying to perfect the use of the abundant natural resources, such as air, water and the electricity of the Earth that was abundant and untouched.

You can read his article, Our Future Motive Power, which talks a lot about it.

  1. Tesla was born during a summer lightning storm

Tesla was born “at the stroke of midnight” during a summer lightning storm. The midwife made a comment that he would be “a child of the storm”, to which his mother replied “No, of light”. They were both right.

  1. Tesla was a humanist

He believed in improving the quality of life through better education and living conditions. He saw ignorance, insanity and religious fanaticism as the “frictional forces which impede progress”. He was also a strong opponent of the countries’ tendencies to spend more on war than on education. This inspired him to take a stand against war with his invention that would end all war – ‘the Teleforce’.

In short, he saw all the unnecessary investments in destructive power as enemies to humanity.

  1. Tesla thought of smartphone technology in 1901!

Tesla was able to envision the 21st century long before it began. In fact, he talked of a system that could collect information, encode it and broadcast it to a hand-held device. This idea came to him while developing the transantlantic radio and it is very similar to today’s mobile internet on our phones.

  1. He had his own mind lab

Tesla had a very strong and precise eidetic memory. Not only could he recall whole books in great detail, but he could also create whole designs and constructions in his mind, which he later used to develop his new inventions. The results he got in his mind while imagining the inventions were incredibly accurate. This meant a lot less physical efforts in achieving results!

  1. The US Government seized and classified Tesla’s stuff after his death

When Tesla died, the Office of Alien Property seized all of Tesla’s documents and schematics and kept them classified. While most of his possessions were later returned to his family or donated to the Tesla Museum in Belgrade, some are still missing, as they remain classified to this day.

  1. Tesla may have had insomnia and OCD

Tesla claimed that he needed only “about one and one-half hours a night” of sleep. He said that “Time spent in sleep is lost time”. He said that there were so many things to do, he didn’t want to spend time sleeping needlessly. This, though, might point to insomnia.

Tesla was also obsessed with the number 3, or in fact with the numbers 3, 6 and 9. He once said: “If you only knew the magnificence of the 3, 6 and 9, then you would have the key to the universe.”

Of course, this does not point to any kind of OCD, but he was obsessed with any number dividable by 3. For example, he cleaned his dining room with 18 napkins before eating his dinner. He also detested jewelry, especially pearls, round objects and touching hair.

  1. Tesla and Edison were not enemies

Despite the popular claim that Edison was Tesla’s arch nemesis, the fact is that they had worked together in designing direct current generators before Tesla left Edison to pursue his dream of the alternating current induction motor.

That’s when they became rivals. Edison made a lot of efforts to put a halt to Tesla’s alternating current, and these involved traveling shows in which he electrocuted elephants with Tesla’s AC.

  1. Tesla made Mark Twain crap his white suit

One of the popular anecdotes about Nikola Tesla was about when he made Mark Twain leave a remarkable stain on his white suit. As all other men who wanted to brag with their ‘new toys’, Tesla was no exception.

After Mark Twain’s complaints about his “recurring bouts of constipation”, Tesla offered him to try out his newest “vibrating humming oscillating metal disc” which he claimed to have “imparted vitality.”

Although the sensation was amazing for Twain, Tesla warned him to step off the platform at a given moment, which he ignored – the following went into history as Mark Twain’s crapped white suit.

  1. You can get free WiFI from Tesla

The Tesla Statue in the Silicon Valley was an idea which originated with Northern Imagination and was backed by 722 people. It was unveiled on December 7, 2013 and it is famous for two things:
– It provides free WiFi signal and
– It contains a time capsule to be opened on January 7, 2043.

Doctors Explain How Hiking Actually Changes Our Brains!

By
Elizabeth Williams

It might seem as such a cliché to say that exercising is important, but now, it is scientifically proven that hiking in nature can actually change our brain!

And the best part is that it doesn’t take too much time or energy, so even people who are overweight or too busy, don’t have any excuses not to do it on a regular basis, as it can truly make a positive difference in everyone’s life!

No more obsessive thoughts and stress!

A study published in Proceedings of the National Academy of Sciences found that spending time in nature significantly decreases negative and obsessive thoughts.

Namely, when we are hiking in a rural environment, we have the opportunity to reconnect with nature, to be present in the moment and to clear our minds. Constant worry and stress can lead to depression, anxiety, ADHD and many other mental illnesses.

However, doctors claim that if we spend at least 150 min. per week in nature we can change our thoughts and behavior in a positive way even when we get back to working or other everyday activities. 

Moreover, another study, conducted by psychologists Ruth Ann Atchley and David L. Strayer showed that creative problem solving can be drastically improved by both disconnecting from technology and reconnecting with nature.

The participants in the study were hiking in nature for 4 days and they were not allowed to use any kind of technology during the experiment.

They were asked to perform tasks which require creative thinking and complex problem solving and the results of the study showed that the participants’ abilities when performing on problem solving tasks improved by 50%. 

Constant urban noise combined with technology can lead to poor cognitive functions, while a long hike without any technology can soothe the mind and boost creative thinking, while lowering stress levels.

Hiking reduces ADHD symptoms in children and boosts brainpower!

Attention Deficiency Hyperactivity Disorder (ADHD) is becoming more and more common among children every day. Due to “over consuming” technology and fast paced life, many children are suffering from lack of concentration and focus, they get distracted easily and they exhibit excessive hyperactivity. 

Many parents turn to drugs as a solution, but the problem can also be solved by spending more time in nature according to a study conducted by Frances E Kup, PhD, and Andrea Faber Taylor, PhD.

Namely, exposing children to “green outdoor activities” significantly decreases the symptoms of ADHD, children exhibit less impulsive behavior and they are able to focus more on given tasks. 

Furthermore, hiking is also linked to increasing the hippocampal volume — the part of the brain associated with spatial and episodic memory, thus improving and preventing memory loss. 

Hiking promotes feelings of well being and it boosts weight loss!

That is right! A study conducted by researchers from the University of British Columbia showed that hiking reduces stress and anxiety, boosts self esteem and helps release endorphins (the happy hormones).

Moreover, this type of aerobic exercise is an excellent way to lose 400-700 calories depending on the hike difficulty and your weight. So not only will you lose weight, you will also feel happier and better about yourself! 

Other benefits from hiking are:

  • It boosts the metabolism
  • It prevents diabetes
  • It strengthens bones and improves bone density
  • It prevents cardiovascular diseases
  • It increases energy levels
  • It lowers the risk of cancer
  • It relieves back pain
  • It provides us with the daily dose of vitamin D, due to sun exposure 
  • It tones the muscles
  • It prevents and even cures insomnia

For these and many other benefits, it is highly suggested to make hiking a part of your daily routine! Even if you don’t have the time to do it every day, just try downloading some map applications on you phone so that you can find various trails around your home and hike as much as you can.

Doing it even once or twice a week will do a positive change in your life!

So go ahead, forget about technology and social media for awhile, take a hike and feel the positive difference!

How we can solve homework problems

By
Elizabeth Williams

Last day I created with another youngster who is bombarding in school since he doesn’t complete his work. He sat over the work zone from me in my office and uncovered to me he consumes through seven hours a day in school and feels he’s “contribute his vitality.”

Homework is an uncalled for weight to drive on top of his troublesome day in school, he says. Or, then again potentially he uncovered to me he has the best of points each day when he returns home from school anyway he can’t constrain himself to open his books.

Or, then again, since this is a composite picture and it’s not just young fellows I work with, perhaps it was a young woman who revealed to me that she’s too much gotten up to speed with completing things partners and doesn’t see the hugeness of homework.

Or, on the other hand maybe she has an occupation after school, which gives her both satisfaction and consuming through money yet forsakes her little time to spend on schoolwork.

Or, then again perhaps the young lives in a family where guideline is not regarded, or where it’s censured, or where the understudy is required to help with kid care or housekeeping and, afresh, has no time for homework.

Failure to do homework drives understudies to crash and burn classes, fizzle assessments, and in the end to drop out of school. I might need to propose a clear response for the homework issue.

Here’s the way it would work. We know most auxiliary schools in the Bound together States track understudies: They offer proficient tracks, school preparatory tracks, general preparing tracks, and regards tracks.

A couple of schools even track inside tracks (by offering high and low school prep classes, for example). I propose we incorporate one more track: a no-homework track. For assistance with assignment for architecture, use this site /architecture-help.html to do his homework.

In this track, understudies would not be alloted homework. In order to pass their classes, they basically would need to go to them reliably and finish the in-class assignments. In case they required help with those assignments, the teacher – or distinctive understudies – would be there to help them.

Evidently, classes without homework would not have the ability to cover a comparative measure of material in a comparative measure of time.

That issue could be grasped by adding greater chance to the no-homework track, either by adding a fifth year to optional school or by having no-homework-track understudies go to summer school for each late spring they’re in auxiliary school.

What are the upsides of this game plan? Here are a couple:

⦁              It would end the homework wars. Watchmen could never again need to fight with their adolescents about completing their work. To be sure, gatekeepers could request that their youngsters be placed in the no-homework track as a way to deal with keep up a key separation from those battles perfect from the start.

⦁              Teachers could never again need to pooch understudies about homework. If homework issues twisted up perceptibly perpetual, teachers could basically propose to understudies that they were set in the wrong track and welcome them to make a meeting with the course educator to request a trade.

A no-homework track would similarly free understudies from the heaviness of concocting novel explanations behind what happened to their homework and why they fail to hand it in.

⦁              Teachers could more eagerly deal with the understudies’ getting of capacities. They could similarly give elective learning or execution techniques. They could fuse examination aptitudes with classes before exams and show kids particular ways to deal with consider.

For understudies who encounter trouble sitting down and scrutinizing a book, they could have them tune into the books on tapes or have them examined parts of books and after that watch movies. For understudies who require help with forming papers, the assistance would be there.

Research Suggests Being Lazy Is A Sign Of High Intelligence

By
Elizabeth Williams

New research appears to demonstrate the hypothesis that brainy individuals invest more energy lazing around than their dynamic partners.

Discoveries from a US-based review appear to bolster individuals with a high IQ get exhausted less effortlessly, driving them to invest more energy for thinking.    

Also, dynamic individuals might be more physical as they have to animate their psyches with outer exercises, either to get away from their considerations or in light of the fact that they get exhausted rapidly.

Scientists from the Florida Gulf Coast University gave a great test – going back three decades – to a gathering of understudies.

The ‘requirement for insight’ poll requested that members rate how emphatically they concur with proclamations, for example, “I truly appreciate an undertaking that includes coming up with new answers for issues”, and “I just think as hard as I need to”.

The scientists, led by Todd McElroy, then chose 30 “thinkers” and 30 ‘non-thinkers’ from the pool of candidates who undergo the research.

Throughout the following seven days both gatherings wore a gadget on their wrist which followed their developments and action levels, giving a steady stream of information on how physically dynamic they were.

The result from the research showed that the thinking group was far less dynamic during that week than the non-thinkers group.

The discoveries of the review, distributed in the Journal of Health Psychology, were portrayed as “highly significant” and “robust” in factual terms.

In any case, the ends of the week demonstrated no contrast between the two gatherings, something which has not possessed the capacity to be clarified.

Analysts recommended the discoveries could loan weight to the possibility that non-thinkers get exhausted all the more effortlessly, so need to fill their time with physical movement.

In any case, the drawback to being brainier – and lazier – cautioned Mr McElroy, was the negative effect of an inactive way of life.

He proposed that the less dynamic individuals, regardless of how cunning they are, ought to plan to raise their general action levels to enhance their wellbeing.

The British Psychological Society cited the review, saying: “Ultimately, an important factor that may help more thoughtful individuals combat their lower average activity levels is awareness.”

Familiarity with their inclination to be less dynamic, combined with a consciousness of the cost related with inertia, more astute individuals may then turn out to be more dynamic for the duration of the day.

The review also included that in spite of highlighting a strange pattern, summing up the discoveries ought to be finished with alert because of the little example of members

6 Natural Ways To Treat Rashes In Infants And Toddlers

By
Elizabeth Williams

Babies remain susceptible to various rashes that become visible on their delicate skin. These can be prevented if you choose the best cloth diaper for wrapping around them. Some traditional treatments for these skin-related disorders are inclusive of antibiotics, steroids, and other treatments.

These mainstream methods have the ability to clear the rashes effectively. However, innate remedies must be given preference because they do not give birth to ill-effects. Also, their application has a soothing effect on the newborns and helps in comforting them.

Moreover, their application is cost-saving as they require the use of basic ingredients that are readily available, at nominal costs, on your visit to the convenience stores. However, it is advised to consult the medical practitioners before applying herbs or oils on the infants.

Some of the rashes that affect newborns are thrush, eczema, diaper rash, and cradle cap.

In the following details, we have listed six natural treatments for rashes that inflict babies.

  1. Oatmeal

You can apply the oatmeal remedy if your little one has developed cradle car or diaper rash. The former arises as a result of the oil glands being over-productive and is identifiable by the appearance of scaly flakes on the newborn’s scalp. The latter is normally caused due to dampened skin and is characterized by reddened skin.

This treatment entails adding 1/3 cup of the organic variety of oatmeal in a blender for obtaining its powdered form. After that, the prepared powder should be mixed with ¼ cup of water. Follow by applying the paste to the afflicted area, and leave for 10 minutes or so.

After that, use water to rinse the body. Pursue by drying the area with a clean towel after which the organic version of olive oil should be massaged to keep their skin moisturized.

  1. Cold Compress

The use of cold compresses soothes the baby’s distressed skin. Also, their application provides comfort to the newborns.

For this remedy, take a washcloth and soak in tepid water. Then, the excess water should be wrung out, and put over the concerned portion. Keep for 8-10 minutes at a time. Repeat this remedy at regular intervals through the day for the babies to recover promptly.

  1. Keep them Diaper-Free

You must allow the permit to be bottomless as much as possible during the day. Not wearing diapers helps them to ‘air-out.’  Also, their skin can breathe, and they can recover quickly.

  1. Coconut Oil

Coconut oil is favored as a remedy for skin-related complaints due to its medicinal nature. It bears the ability to keep the skin hydrated; thereby, accelerating the healing course.

Coat the baby’s skin with a thin layer of coconut oil, regularly, for enjoying its rich remedial value.

  1. Breast Milk

For treating diaper rash, you can also consider applying breast milk over the rashes for the healing process to ensure. Take few drops and rub gently over their troubled skin. Let it air dry and then wrap around a fresh diaper.

  1. Herbal Tea

If you notice that your newborn’s skin has become scaly and dry, it is possible that they are suffering from Eczema. In such cases, you should prepare tea and apply the preparation over the irritated skin.

For preparing tea, boil 2 cups of water after which you should add one teabag each of nettle leaf and chamomile herb. Let the tea cool and follow by soaking a washcloth in the mixture. Apply the wet washcloth around the rashes.

Eczema is also known to cause itching. For relieving the infants from the associated discomfort, you can try adding the oatmeal powder to a bathtub of lukewarm water and mixing thoroughly. Soak the baby in the mixture for 20 minutes and then dry using a towel.

Pursuing natural treatments for your baby’s rashes is advised as these remedies are safe and easy-to-practice. Baby skin is tender and exposing them to harsh treatments can prove to be highly painful for them.

The home remedies serve as an ideal option for the treatment of baby rashes because of their painless nature. Moreover, they are highly effective. We advise you opt for them first before subjecting your mini-versions to the advanced systems.

10 Things People Don’t Realize You’re Doing Because You’re Repressing The Hell Out Of Your Feelings

By
Elizabeth Williams

There are all sorts of people in the world; in a lifetime, you’ll get a chance to interact with a myriad of personalities, outgoing, pleasant, disturbing and so on and so forth. Some say that being an outgoing person that expresses one’s feeling is the best thing there is. True? Who knows?

I am quite the opposite. I find it hard to interact with people I don’t know; it takes a lot out of me to befriend someone new. But that’s not all. I also belong to the category of people who don’t express their feelings. You know, the ones that are prone to emotional repression.

To be quite honest, it has done its damage over the years, but there is nothing I can do. It’s just the way I am. If something is bothering me, I’m not the kind of person that will outright say what it is that troubles me.

It’s not something my parents taught me or something I acquired along the way; I was born that way. Even as a child, I remember people, relatives and friends, commenting on my “reserved” personality.

Are you the same type? Do you tend to repress your feelings until they burst out like an erupting volcano?

Here’s how we unconsciously deal with our unexpressed feelings: 

1.Dealing with someone else’s emotions is way easier than dealing with your own. Do you do this? I sure do. I often try to help my friends with their issues and rarely speak of my own.

Probably because I’m afraid to confront my emotions and confronting someone else’s emotions is no “biggie”. I’m usually the “shoulder to cry on” and people often refer to me as “strong” and “brave”. Not true. I have plenty of fears but rarely do I express what’s on my mind.

2. Ditching friends and disappearing for a while. Whenever someone doesn’t act or react the way I expect them to, I find that I am disappointed in that particular person and I always take some time off. Meaning, I don’t call, I don’t ask them out…

I basically disappear from their lives until the uneasiness settles. It usually does and those who know me, don’t take it to heart. I’ve had the same friends for decades and they do admit that it bothers them, but they know that I’m an introvert and that something provoked that reaction on my part, so there’s never any hard feelings. Still, not a good way to deal with a situation.

3. The best way to avoid facing your feelings and fears: keep busy! I’m basically a workaholic. I love working, love chores, love tidiness. If I’m busy, I don’t have time to think or to deal with my emotions.

4. Irrational anxieties pop up all over the place. Repressed emotions will surface one way or the other. You can’t hide from them, you can’t erase them, so developing a number of irrational fears and anxieties is the side-effect. I’m scared of all sorts of things, I think about things a normal person doesn’t – a plane crash, my parents dying of cancer and so on. It never ends.

5. I’m fine. Remember when Ross constantly claimed he was fine with Rachel dating Joey? That’s what happens when you repress your emotions. You keep on saying “I’m fine” even when you’re not.

6. Every cloud has a silver lining – that’s what you cling onto when you try to deal with a negative situation that has prompted negative feelings. You try to put a positive spin on everything and you think it works. It doesn’t. It will come back to bite you in the ass.

7. Being a control freak – trying to control everything, all the time, trying to plan every single future step you take. That’s another thing that keeps you “safe”.

8. Always picking the wrong guy/girl – why? Because that way you feel emotionally protected, you think… scratch that, you know that you won’t get emotionally attached or too intimate. 

9. It’s all just a big joke you – you keep turning every grim situation into a joke, trying to laugh it off and keep the pain at bay. That’s another way of dealing with your emotions.

10.Nothing can touch you, you are rock solid. You always present yourself as a strong person, nothing can touch you, but there is no such thing as a person without emotions, so hard as you might try to portray yourself as strong, people know better than to judge a book by its “rock” solid cover.

Scientists Grow Full-Sized Beating Human Hearts From Stem Cells

By
Elizabeth Williams

So many people in the world are waiting for new hearts. And getting a heart doesn’t mean that the struggle is over. After a person gets a heart transplant, a new obstacle, just as perilous as the first, has to be overcome – will the body accept the new heart.

There are so many issues that need to be overcome, it’s overwhelming. However, a new scientific development just might hold the key to overcoming the greatest obstacles in human heart transplantation procedures.

Namely, a team of scientists from Massachusetts General Hospital and Harvard Medical School have made great strides in overcoming the major issues of organ shortage by using adult skin cells to regenerate functional human heart tissue.

What does this mean? Well, it means that they managed to grow a full-sized, beating human heart from stem cells.

According to their paper “Bioengineering Human Myocardium on Native Extracellular Matrix” published in Circulation Research, over 25 million people all over the world suffer from heart failure. Nearly 4000 patients a year in the US are on the waiting list for heat transplants, but only around 2500 per year will get the heart they need.

Thanks to this newly developed technique in which the scientists use adult skin cells to regenerate functional human heart tissue, there is much hope that one day everyone that needs a new heart, will get it and will be able to live a long and healthy life.

In their study, the scientists used a technique that was used in mouse hearts,  but this time they used it on human hearts. By stripping away many of the cell on 73 donatedhuman hearts that were recovered by the New England Organ Bank and were deemed unusable for clinical transplantation, the scientists were able to use their newly developed technique to turn them into pluripotent stem cells.

This means that these cells were turned into cells that can become specialized to any type of cell in the body. Then, these cells were induced to become two different types of cardiac cells that were grown under constant surveillance for two weeks.

 During those two weeks, the scientists infused the hearts with a nutrient solution and after the two weeks, the newly grown tissue looked like real human hearts that started beating only after they were given electricity shocks.

“To provide a clinically relevant tissue scaffold, we translated perfusion-decellularization to human scale and obtained biocompatible human acellular cardiac scaffolds with preserved extracellular matrix composition, architecture, and perfusable coronary vasculature,” the scientists state in their paper.

“We then repopulated this native human cardiac matrix with cardiomyocytes derived from nontransgenic human induced pluripotent stem cells and generated tissues of increasing 3-dimensional complexity.

We maintained such cardiac tissue constructs in culture for 120 days to demonstrate definitive sarcomeric structure, cell and matrix deformation, contractile force, and electrical conduction.”

It does sound promising, but the scientists say there is much more work to be done. Their next step is to boost the yield of pluripotent stem cells and quicken the growing process.

Also, they claim that the body-like conditions in which the hearts are grown, need to be perfected. All in all, this is a great leap for humanity – a ray of hope that one day everyone that needs a heart will get a heart and the possibility of a rejected heart transplant will be completely eliminated.
