OBJECTIVES To describe a standard clinical protocol for the objective assessment of manual wheelchair propulsion; to establish preliminary values for temporal and kinetic parameters derived from the protocol; and to develop graphical references and a proposed application process for use by clinicians. DESIGN Case series. SETTING Six research institutions that collect kinetic wheelchair prop...

BACKGROUND Floor dust is commonly used for microbial determinations in epidemiological studies to estimate early-life indoor microbial exposures. Resuspension of floor dust and its impact on infant microbial exposure is, however, little explored. The aim of our study was to investigate how floor dust resuspension induced by an infant's crawling motion and an adult walking affects infant inhalat...

OBJECT Falls are the most common accident scenario in young children as well as the most common history provided in child abuse cases. Understanding the biomechanics of falls provides clinicians with objective data to aid in their diagnosis of accidental or inflicted trauma. The objective of this study was to determine impact forces and angular accelerations associated with low-height falls in ...

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...
