Fresh Ag nanoparticles (NPs) dispersed on a transparent SiO2 exhibit an intense optical extinction band originating in localized surface plasmon resonance (LSPR) the visible range. The intensity of LSPR weakened when NPs was stored ambient air for two weeks. rate weakening and wavelength shift, corresponding to visual chromatic changes, strongly depended environment which were set. origin chang...

Article history: Received 22 December 2016 Accepted 27 December 2016 clinically relevant increase in theQT interval, especially in consideration that these were LQTS patients, and thus expected to have a prolonged QT intervals to begin with. As analogy, the guidelines for LQTS indicate that whenever mexiletine shortens the QTc by at least 40 ms it should be added to beta-blockers for chronic th...

introduction: the greatest part of constructed dams belongs to embankment dams and there are many examples of their failures throughout history. about one-third of the world’s dam failures have been caused by flood overtopping, which indicates that flood overtopping is an important factor affecting reservoir projects’ safety. moreover, because of a poor understanding of the randomness of floods...

background: synthetic dyes have several harmful effects on human health as well as aquatic life. in this study, activated carbon (av-ac), based on aloe vera leaf shells, was used as a novel agricultural adsorbent, one that is low-cost and available for the removal of congo red (cr) as a carcinogenic dye from aqueous solutions. methods: in the batch system, the influence of different parameters ...

background : an outbreak investigation was carried out to determine the cause and confirm the source of food poisoning in deptsang village for implementing prevention and control measures. methods : we conducted a retrospective cohort study for the outbreak investigation. stool specimens were collected from cases to perform culture and antibiogram. the team also inspected the environment and hy...

in the present work, the znfe2o4 nanoparticle has been successfully synthesized. the obtained sample was characterized by x-ray diffraction (xrd), emission scanning electron microscopy (fe-sem) and its optical property was examined by uv-vis spectrophotometer. fe-sem revealed that the particle size of the znfe2o4 of about 47 nm was synthesized. the photocatalytic performance under uv-vis and vi...
