BACKGROUND Several studies have reported the potential value of the dual-task concept during locomotion in clinical evaluation because cognitive decline is strongly associated with gait abnormalities. However, current dual-task tests appear to be insufficient for early diagnosis of cognitive impairment. METHODS Forty-nine subjects (young, old, with or without mild cognitive impairment) underw...
Prevention strategies that delay the onset of asthma may improve clinical outcomes. To identify early life environmental exposures associated with asthma age-of-onset and potential genetic modifiers of these exposures, we studied 1085 subjects with physician-diagnosed asthma and disease onset at or after age two. Subjects reported retrospectively on their exposure to 17 environmental factors be...
BACKGROUND Musculoskeletal pain (MSP) is a common and disabling problem among carpet weavers and is linked to physical and psychosocial factors of work. This study aimed to determine the prevalence of MSP, its psychosocial risk factors, and association of pain in each pair of anatomical sites among carpet weavers. METHODS A cross-sectional study was performed among 546 hand-woven carpet weave...
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.
