abstract background and purpose: overweight and obesity are the health problem in adolescents and the main purpose of this study was to evaluate this problem and some socio-demographicrelated factors among two ethnic groups in iranian northern primary school children in 2010. materials and methods: this was a descriptive and cross-sectional study that performed on 4165 students (turkman = 2852a...
The Iranian Carpet Museum collection contains the most valuable specimens of rugs from the ninth century AH to the contemporary period and is a rich source of research for researchers and art friends. Carpet Museum carpets and carpets, according to their quality and antiquity and taking into account the characteristics of carpet in terms of color, design, role, texture and variety of carpet wea...
The existing standards for measuring carpet properties consider carpet behavior after loading while its dynamic and instantaneous behavior is neglected. To investigate the dynamic behavior of under loading carpets, an INSTRON machine equipped with a developed system was used. The reliability of the system was verified by testing different materials. Different samples of hand-knitted carpet with...
In this research, an apparatus was designed and constructed in order to simulate the storage behavior of hand-woven carpet under different environmental conditions. Silk hand-woven carpet (“Gom”) with 115×75 cm dimensions and 102×97 knot per 10 cm was selected and then inserted into the packing simulator with two different laying configurations including flat and folded....
Animals at the bottom of the sea survive oxygen depletion surprisingly often, and a new study identifies cable bacteria in the sediment as the saviors. The bacterial electrical activity creates an iron 'carpet', trapping toxic hydrogen sulfide.
Similar to the mechanism by which a visco-elastic mud damps the energy of overpassing surface waves, if the near-shore seafloor is carpeted by an elastic thin material attached to generators (i.e. dampers) a high fraction of surface wave energy can be absorbed. Here we present analytical modeling of the flexible carpet wave energy converter and show that a high efficiency is achievable. Express...
