Abstract: Stairway Ushtobin Village is one of the five villages with original and sustainable architecture in Northwest of Iran along the border of Armenia, which has been able to maintain its environment and sustainable ecosystem. Studying circulation, function and scale (grand, medium and minor) of space, ratio of full and empty spaces, number and height of stairs, ratio of compound volume to luxury spaces, openings, type of local masonry (stone, mud, wood) and form of covering elements have been carried out in four houses of this village comparatively as some samples in this article, and furthermore, this article analyzes that the architectural shapes and organic texture of the village meet the needs of cold and dry climate. Finally, some efficient plans are offered suiting the present needs of the village to have a sustainable architecture.
Abstract: In the study of chironomids in Armenia several
species of Orthocladiinae subfamily of Cricotopus genus,
Diamesinae subfamily of Diamesa genus, and Chironominae
subfamily of Chironomus genus, have been identified. In the
Cricotopus genus two sibling species were found, not distinguishable
by larval morphological features, but clearly distinct cytogenetically.
Abstract: Five original strains of entomopathogenic bacteria
with insecticidal activity against mosquito larvae of the genera Aedes,
Culex and Anopheles have been isolated from natural conditions in
Armenia and characterized. According to morphological,
physiological and biochemical parameters, all isolates were identified
as Bacillus thuringiensis spp. israelensis (Bti). High larvicidal
activity has been showed by three strains Bti. These strains can be
recommended for industrial production of bacterial preparations.
Abstract: The possibility of radionuclides-related contamination
of lands at agricultural holdings defines the necessity to apply special
protective measures in plant growing. The aim of researches is to
elucidate the influence of polymers applying on biological migration
of man-made anthropogenic radionuclides 90Sr and 137Cs in the
system water - soil – plant. The tests are being carried out under field
conditions with and without application of polymers in root-inhabited
media in more radioecological tension zone (with the radius of 7 km
from the Armenian Nuclear Power Plant). The polymers on the base
of K+, Caµ, KµCaµ ions were tested. Productivity of pepper
depending on the presence and type of polymer material, content of
artificial radionuclides in waters, soil and plant material has been
determined. The character of different polymers influence on the
artificial radionuclides migration and accumulation in the system
water-soil-plant and accumulation in the plants has been cleared up.
Abstract: The data presented in this work show that in Armenia
a rise of air temperature is expected in the season, and annual terms.
As a result of the noted increase in temperature, a significant growth
of vulnerability of the territory of Armenia in relation to malaria is
expected. Zoning by the risk of renewed malaria transmission has
been performed.
Abstract: Taking into account the importance of Lake Sevan and
Lake Sevan basin-s rivers for Armenian economy, the main goals of
our investigations were the documentation of water quality and the
biodiversity of invertebrates developed in Lake Sevan basin-s rivers
and selected tributaries.
Moderately satisfied ecological condition for the biodiversity of
Lake Sevan basin-s rivers has been established, and the changes in
species- composition of zoobenthos in Lake Sevan were detected.
A growing tendency of antibiotic resistance among E. coli isolates
in water resources has been shown.
Abstract: The Zung self-depression scale and Beck Anxiety Inventory were used to study the depression and anxiety levels of Armenian Crohn's disease patients, as well as to reveal the relation between emotional status and placebo effect of these patients. Despite of registered high levels of depression and anxiety, the high placebo rate during investigations was described. The importance of use of psychotherapies for optimal outcomes during treatments of Crohn's disease is obvious.
