Forum Rules (Everyone Must Read!!!)

1] What you CAN NOT post.

You agree, through your use of this service, that you will not use this forum to post any material which is:
- abusive
- vulgar
- hateful
- harassing
- personal attacks
- obscene

You also may not:
- post images that are too large (max is 500*500px)
- post any copyrighted material unless the copyright is owned by you or cited properly.
- post in UPPER CASE, which is considered yelling
- post messages which insult the Armenians, Armenian culture, traditions, etc
- post racist or other intentionally insensitive material that insults or attacks another culture (including Turks)

The Ankap thread is excluded from the strict rules because that place is more relaxed and you can vent and engage in light insults and humor. Notice it's not a blank ticket, but just a place to vent. If you go into the Ankap thread, you enter at your own risk of being clowned on.
What you PROBABLY SHOULD NOT post...
Do not post information that you will regret putting out in public. This site comes up on Google, is cached, and all of that, so be aware of that as you post. Do not ask the staff to go through and delete things that you regret making available on the web for all to see because we will not do it. Think before you post!

2] Use descriptive subject lines & research your post. This means use the SEARCH.

This reduces the chances of double-posting and it also makes it easier for people to see what they do/don't want to read. Using the search function will identify existing threads on the topic so we do not have multiple threads on the same topic.

3] Keep the focus.

Each forum has a focus on a certain topic. Questions outside the scope of a certain forum will either be moved to the appropriate forum, closed, or simply be deleted. Please post your topic in the most appropriate forum. Users that keep doing this will be warned, then banned.

4] Behave as you would in a public location.

This forum is no different than a public place. Behave yourself and act like a decent human being (i.e. be respectful). If you're unable to do so, you're not welcome here and will be made to leave.

5] Respect the authority of moderators/admins.

Public discussions of moderator/admin actions are not allowed on the forum. It is also prohibited to protest moderator actions in titles, avatars, and signatures. If you don't like something that a moderator did, PM or email the moderator and try your best to resolve the problem or difference in private.

6] Promotion of sites or products is not permitted.

Advertisements are not allowed in this venue. No blatant advertising or solicitations of or for business is prohibited.
This includes, but not limited to, personal resumes and links to products or
services with which the poster is affiliated, whether or not a fee is charged
for the product or service. Spamming, in which a user posts the same message repeatedly, is also prohibited.

7] We retain the right to remove any posts and/or Members for any reason, without prior notice.


Members are welcome to read posts and though we encourage your active participation in the forum, it is not required. If you do participate by posting, however, we expect that on the whole you contribute something to the forum. This means that the bulk of your posts should not be in "fun" threads (e.g. Ankap, Keep & Kill, This or That, etc.). Further, while occasionally it is appropriate to simply voice your agreement or approval, not all of your posts should be of this variety: "LOL Member213!" "I agree."
If it is evident that a member is simply posting for the sake of posting, they will be removed.

8] These Rules & Guidelines may be amended at any time. (last update September 17, 2009)

If you believe an individual is repeatedly breaking the rules, please report to admin/moderator.

    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.

    "In the previous contest we were among four teams which won money
    prizes and this year we became the national winner," 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.

    "We have accomplished a great deal, and our biggest achievement is
    that we have got Armenian and international patents," Shmavonyan said.

    He said the $10,000 his team won in 2014 was spent on necessary
    equipment. "We will have prototypes of an appropriate container,"
    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

    "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.

    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

    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

    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

    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

    This image shows stone tools found at the site of Nor Geghi, Armenia:
    top - biface tool; bottom - a Levallois core. Image credit: (c) Dan

    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.

    Middle Paleolithic transition in the Southern Caucasus. Science, vol.

    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

    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.
