NANO HI WINS ARMENIA'S NATIONAL CLEANTECH BUSINESS IDEAS COMPETITION 2015
YEREVAN, October 14. /ARKA/. Nano Hi has won Armenia's National
Cleantech Business Ideas Competition 2015.
Gagik Shmavonyan, the head of the company, told ARKA News Agency that
Nano Hi has taken part in the contest for two consecutive years now.
Â"In the previous contest we were among four teams which won money
prizes and this year we became the national winner,Â" he said.
In his words, his team competed with a technology for production a
water bottle in the previous contest, and now it presented thermo
photo voltaic containers.
To produce this container, the company has been working in nano
technology area over 15 years.
Â"We have accomplished a great deal, and our biggest achievement is
that we have got Armenian and international patents,Â" Shmavonyan said.
He said the $10,000 his team won in 2014 was spent on necessary
equipment. Â"We will have prototypes of an appropriate container,Â"
he added.
The main aim of the contest is to put innovative ideas into practice
and to support innovators. Armenia held its first contest in 2014.
Armenia was the first country in Eastern Europe to join UNIDO GEF
Global Cleantech Innovation Program for SMEs.
Some 24 companies presented their business ideas to jurors, who
singled out the best ideas, of which the national winner was chosen.
The selected teams get $10,000 for developing their ideas, and the
representatives of Ecotechnology, the company representing the national
winner, will attend in November the annual Global Forum in Silicon
Valley, where they present their business model to venture funds,
investors and experts.
The duration of the Global Cleantech Innovation Program for SMEs
in Armenia is three years. The aim of the program is to support
startup small and medium companies that use clean technologies and
to encourage innovators.
National partners of the program are the Armenian nature protection,
economy, energy and natural resources and agriculture ministries.

5,000-Year-Old Throne Found in Turkey
By Rossella Lorenzi
Sep 18, 2015
The remains of a 5,000-year-old adobe basament of a possible "throne"
have been unearthed during excavations in Turkey, revealing the
origins of the secularization of power and one of the first evidence
of the birth of the state system.
Discovered in Aslantepe in the eastern Turkish province of Malatya,
the structure consists of an adobe platform, raised by three steps
above the floor, on top of which burnt wooden pieces were found.
"The burnt wooden fragments are likely the remains of a chair or
throne," excavation director Marcella Frangipane of La Sapienza
University in Rome, told Discovery News.
Frangipane, who has long been digging at the site, is working to bring
to light a huge complex dating to the fourth millennium B.C.
(3350-3100 B.C.)
"It's the world's first evidence of a real palace and it is extremely
well preserved, with walls standing two meters high," Frangipane said.
The complex features two temples, storage rooms, various buildings and
a large entrance corridor. Some walls are decorated with red and black
motifs and with geometrical impressed patterns.
"In the past two campaigns we found a large courtyard which can be
reached through the corridor. On the courtyard stands a monumental
building," Frangipane said.
Within such building, the archaeologists unearthed the adobe platform.
It stood in a small room which opened into the courtyard.
Frangipane believes the chief or king appeared in the throne room to
give audience to the public, gathered in the large courtyard.
In front of the platform where the throne likely stood, the
archaeologists also unearthed two small and low adobe platforms,
probably made for people to stand on while they appeared before the
king.
"This reception courtyard and building were not a temple complex, they
rather appear as the heart of the palace. We do not have religious
rites here, but a ceremony showing the power of the 'king' and the
state," Frangipane said.
She noted the remains are the first evidence of a change in the
exercise of power, which from theocratic becomes non-religious.
Usually exerted in temples, power now happens in the throne room.
"The state governing system was already in progress here," Frangipane said.

Re: News in Science
CANADIAN ANYA POGHARIAN INVENTS NEW DIALYSIS MACHINE
February 9, 2015
CBC, Montreal - Seventeen-year-old Anya Pogharian's high school science
project could end up changing the way dialysis care is delivered.
After poring over online dialysis machine owner's manuals, she
developed a new prototype using simple technology.
While machines currently cost about $30,000, hers would cost just
$500 -- making it more affordable for people to buy and have at home.
Pogharian was inspired by volunteering at a hospital dialysis unit.
When she was assigned a high school science project, she chose to work
on a new kind of dialysis unit. She spent 300 hours on her invention --
well above and beyond the mandatory 10 hours.
Dialysis is the process of cleaning waste from the blood. It's
typically used for people who have kidney disease. The treatment
takes about four hours a couple times per week.
Pogharian said she wanted to find a way to improve the procedure,
which can be hard on patients.
"It takes a lot of energy out of them," said Pogharian. "They're very
tired after a dialysis treatment."
"You wouldn't have to make your way to the hospital, which is a
problem for a lot of patients. It's not necessarily easy to make
your way to the hospital three times a week, especially it you have
limited mobility," she said.
Testing it out
Her project has earned her a slew of scholarships and awards. Now,
Hema-Quebec has offered her a summer internship, to try out her
invention with real blood.
"All the population will benefit from that kind of instrument that
will reduce medical care cost, hospitalization stays. Basically,
it's a great idea," said Louis Thibault, director of applied research
at Hema-Quebec.
Pogharian said she hopes one day, her invention will be used overseas.
"Ten per cent of patients living in India and Pakistan who need
the treatment can't afford it or can't have it in any way. It's not
accessible. So that motivated me."
But Pogharian says she's focusing on doing well on her CEGEP midterm
exams.

ARMENIANS INVENT A DEVISE TO PRINT PHOTOS FROM INSTAGRAM
15:06, 05 Dec 2014
Russia-based Armenians Tos Movsisyan and Artem Germeryan have invented
a device that prints photos from Instagram, which has no analogue in
the world, Russian Vedomosti reports.
Instagram is the most positive social network. Photos on Instagram
always express emotions. That's why Tos Movsisyanfrom Moscow and Artem
Germeryan, a resident of Saint Petersburg, decided to materialize them.
They created the Boft devise, which prints square photos immediately
form the user's profile, and the profile opens on a large touch
screen. The printing of two photos costs 50 rubles. Four and 20 photos
will cost 100 and 500 rubles respectively.
The two met at the Lappeenranta University of Technology, where the
students were sent to study by their universities. "Where else could
two Russian-speaking Armenians meet, if not in Finland?" Movsisyan
jokes.
Movsisyan and Germeryan invested $200 000 in the business. They spent
over a year to develop the software and the devise itself and to find
a company that would agree to produce the necessary equipment.
There are currently 10 Boft devises installed in Moscow trade center,
and another three in Saint Petersburg. The entrepreneurs intend to
install 150 devises all over Russia in 2015 and hope to reach the
US market.

Stone Tool Discovery in Armenia Gives Insight into Human Innovation
325,000 Years Ago
Sep 27, 2014 by Sci-News.com
An analysis of about 3,000 stone tools from a 325,000-year-old
archaeological site near the village of Nor Geghi in the Kotayk
Province of Armenia challenges the theory held by many scientists that
the so-called Levallois stone tool-making technique was invented in
Africa and then spread across the world as the human population
expanded.
This image shows stone tools found at the site of Nor Geghi, Armenia:
top - biface tool; bottom - a Levallois core. Image credit: (c) Dan
Adler.
Named after flint tools discovered in the 19th century in the
Levallois-Perret suburb of Paris in France, Levallois technique is a
distinctive style of flint knapping developed by early humans during
the Paleolithic.
This technique involves the multistage shaping of a mass of stone in
preparation to detach a flake of predetermined size and shape from a
single preferred surface.
Many anthropologists argue that Levallois technique was invented in
Africa more than 300,000 years ago and spread to Eurasia with
expanding human populations, replacing a more basic type of technology
- biface technique - in which a raw block of stone is shaped through
the serial removal of interrelated flakes until the remaining volume
takes on a desired form, such as a hand axe.
But now a team of archaeologists and anthropologists from the United
States and Europe led by Dr Daniel Adler of the University of
Connecticut has discovered at the Armenian archaeological site of Nor
Geghi that Levallois tools already existed there between 325,000 and
335,000 years ago, suggesting that local populations developed them
out of biface technique, which was also found at the site.
The co-existence of the two techniques provides the first clear
evidence that local populations developed Levallois technique out of
existing biface technique.
"The discovery of thousands of stone artifacts preserved at this
unique site provides a major new insight into how Stone Age tools
developed during a period of profound human behavioral and biological
change", said Dr Simon Blockley of Royal Holloway, University of
London, who is a co-author of the paper describing the discovery in
the journal Science.
"The people who lived there 325,000 years ago were much more
innovative than previously thought, using a combination of two
different technologies to make tools that were extremely important for
the mobile hunter-gatherers of the time."
Moreover, the chemical analysis of several hundred obsidian tools from
Nor Geghi shows that early humans at the site utilized obsidian
outcrops from as far away as 120 km, suggesting they must have been
capable of exploiting large, environmentally diverse territories.

Re: News in Science
Tree that bears 40 different fruit: magical-looking plant produces
varieties of peaches, plums, apricots, cherries
18:40 * 25.07.14
Incredible 'magical' trees that bear 40 different varieties of fruit have
been popping up all over US, the Daily Mail reports.
These trees - which can simultaneously produce different varieties of
peaches, plums, apricots, nectarines and cherries - look ordinary
throughout most of the year.
But in spring, they bloom into a stunning patchwork of colors, with each
tree featuring its own unique selection of stone fruit.
They are the work of Syracuse University sculptor and artist Sam Van Aken
who created the trees in an attempt to make people reconsider how food can
be produced.
The project began in 2008 when Mr Van Aken discovered that a New York state
orchard, which held varieties of stone fruit 200-years-old, was to be
abandoned.
In hopes of saving it, the artist bought the orchard, and soon after
started experimenting with something known as 'chip grafting.'
The process involves taking a sliver off a tree, including the bud, and
inserting that into a cut in the working tree.
The foreign tree part is then taped and left to heal over the winter. Mr
Van Aken explained that most stone-fruits are easily compatible.
What he came up with is 'The Tree of 40 Fruit', which is in fact, not one
tree, but a series of hybridised fruit plants.
So far, Mr Van Aken has created and placed 16 trees in museums, community
centres and private art collections around the U.S..
In spring, the trees blossom in shades of pink, crimson and white, and in
summer, they bear a range of stone fruit.
'I've been told by people that have [a tree] at their home that it provides
the perfect amount and perfect variety of fruit,' Mr Van Aken told Lauren
Salkeld at Epicurios.
'So rather than having one variety that produces more than you know what to
do with, it provides good amounts of each of the 40 varieties.
'Since all of these fruit ripen at different times, from July through
October, you also aren't inundated,' he said.
Mr Van Aken's trees can be seen in cities across the U.S., including Santa
Fe, New Mexico; Short Hills, New Jersey; Louisville, Kentucky and Pound
Ridge, New York.
