objective: to determine the type and pattern of arrhythmic events following the 2012 ahar-varzegan earthquake among patients implanted with cardiac defibrillators (icds) in east azarbaijan province. methods: in a prospective cohort study, conducted in east azerbaijan province of iran, 132 patients were enrolled in two comparison groups according to the region of residence i.e., earthquake regio...

Parallel manipulators are increasingly used in new applications by exploiting their better characteristics with respect to those of serial manipulators, such as higher stiffness, velocity and acceleration, payload. In this paper, experimental results are presented of a novel application of a 3-DOF CaPaMan (Cassino Parallel Manipulator) prototype to simulate point seismograms and 3D earthquake m...

Photoconductivity-based measurements of recombination lifetimes in multicrystalline silicon are often hampered by carrier trapping effects, which cause a characteristically large relative increase in the photoconductance. Single-crystal p-type float-zone wafers of varying resistivities were cross contaminated with multicrystalline wafers that exhibited such trapping. A proportion of the impurit...

The TabaseColshan catastrophic earthquake of 16 September 1978 of magnitude M ~ 7 . 7 , the largest shock which has ever been recorded in Iran, occurred in Khorassan Province east central Iran (Fig. 1). The main shock took place in the evening, when most people were in their houses, at 19.38.18 local time (1535.58 GMT), without any felt foreshock. The preliminary instrumental epicentre is recor...

background:  this  study  aimed  to  prospectively  analyze  the  effect  of  a  major  earthquake on the prevalence of psychological disorders such as acute stress disorder (asd), anxiety, depression,  mixed  anxiety  depression  disorder  (madd),  phobia,  aggressive  behavior, insomnia, psychosomatic disorders and also sociodemographic aspects among residents of rural community sample in eas...

Biochemical reactions that occur in sewer pipes produce a considerable amount of hydrogen sulfide gas (H2S corrosive and poisonous), methane gas (CH4 explosive and a major climate change contributor), carbon dioxide (CO2 a major climate change contributor), and other volatile substances (collectively known as in-sewer gases). These toxic gases lead to contamination of natural environment, sewer...

Floating multi-layer coated tablets were designed based on gas formation. The system consists of a drug-containing core tablet coated with a protective layer (hydroxypropyl methylcellulose), a gas forming layer (sodium bicarbonate) and a gas-entrapped membrane, respectively. The mechanical properties of acrylic polymers (Eudragit RL 30D, RS 30D, NE 30D) and ethylcellulose were characterized by ...

[1] Eddy diffusivities in the Labrador Sea (LS) are estimated from deep eddy resolving float trajectories, moored current meter records, and satellite altimetry. A mean residence time of 248 days in the central LS is observed with several floats staying for more than 2 years. By applying a simple random walk diffusion model, the observed distribution of float residence times in the central LS c...
