Mesoporous microspheres with a larger pore size (diameter of pore: ca. 35 nm, Barrett-Emmett-Teller (BET) surface area: 25.6 m/g), the radial arrangement of irregular BaSO4 nanorods, were successfully synthesized by the radiolysis of an aqueous solution of K2S2O8, Ba(NO3)2, and disodium ethylenediaminetetraacetate with an irradiation time of 1000 min (dose rate: 20 Gy/min) at room temperature. ...
BACKGROUND The link between concentrations of particulate matter (PM) and respiratory morbidity has been investigated in numerous studies. OBJECTIVES The aim of this study was to analyze the role of different particle size fractions with respect to respiratory health in Beijing, China. METHODS Data on particle size distributions from 3 nm to 1 µm; PM10 (PM ≤ 10 µm), nitrogen dioxide (NO(2))...
hypothermia generates potentially severe complications in operating or recovery room. forced air warmer is effective to maintain body temperature. extremely low frequency electromagnetic field (elf-emf) is harmful to human body and mainly produced by electronic equipment including convective air warming system. we investigated elf-emf from convective air warming device on various temperature se...
background and purpose: the objective of medical education is to train competent and qualified workforce in order to provide services in various health environments. one of the important objectives of operating room students is to train workforce who can involve in patient’s health and recovery. training these students should cause clinical ability and independent decision making during surgery...
color has the ability to inspire, excite, soothe, heal and even agitate. this is particularly true for children, who can be extra sensitive to color's impact. so the importance of picking out just the right color for a young child's room shouldn't be underestimated. when choosing colors to use for your rooms home it's important to think about the mood you want to create and ...
background: radon and its daughter product are a major source of natural radiation exposure, the measurement of radon concentration in dwellings is assuming ever increasing importance. it is known from recent surveys in many countries that radon and its progeny contributes significantly to total inhalation dose and is well established that radon when inhaled in large quantity causes lung disord...
