Isotropic diffuse gamma-ray flux in the PeV energy band is an important tool for multimessenger tests of models origin high-energy astrophysical neutrinos and new-physics searches. So far, this has not yet been observed. Carpet-2 air-shower experiment capable detecting gamma rays with energies above 0.1 PeV. Here we report upper limits on isotropic from data obtained 1999-2011 2018-2022. These ...

The Textile Museum & The International Hajji Baba Club Washington D.C. June 19, 2004 Introduction Handmade carpet production in Iran goes back to the history, of which is not the subject of this short paper and presentation. Carpet production and in general carpet culture especially in rural areas is combined and mixed with every-day life of many people. In rural places, almost all the women...

Several earlier studies have shown the presence of more dust and allergens in carpets compared with non-carpeted floors. At the same time, adverse effects of carpeted floors on perceived indoor air quality as well as worsening of symptoms in individuals with asthma and allergies were reported. Avoiding extensive carpet use in offices, schools, kindergartens and bedrooms has therefore been recom...

Drosophila melanogaster head development represents a valuable process to study the developmental control of various organs, such as the antennae, the dorsal ocelli and the compound eyes from a common precursor, the eye-antennal imaginal disc. While the gene regulatory network underlying compound eye development has been extensively studied, the key transcription factors regulating the formatio...

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...
