introduction: skin sparing is one of the most desirable characteristics of high energy photon beams. however, the photons emerging from the target of linacs are contaminated by secondary electrons as a result of their interactions with air, collimators, flattening filter and any other objects in their path. this phenomenon tends to increase the skin dose received b...

background: the electrocardiogram artifact is a major contamination in the electromyogram signals when electromyogram signal is recorded from upper trunk muscles and because of that the contaminated electromyogram is not useful. objective: removing electrocardiogram contamination from electromyogram signals. methods: in this paper, the clean electromyogram signal, electrocardiogram artifact and...
in this thesis protic and aprotic ammonium-based ionic liquids were synthesized and their surface tensions were measured in the range of 298-373k. the protics are alkyl ammonium-based ils with the carboxylate (formate, acetate, propionate) anion and aprotics are quaternary ammonium-based ils with bis(trifluoromethylsulfonyl)imide anion. capillary rise method was used for surface tension measure...
Intra-ovum infection of artificialy contaminated salmonid (rainbow trout or amago salmon) eggs was studied using three fish pathogens (Flavobacterium psychrophilum, Renibacterium salmoninarum and Aeromonas salmonicida). Artificial contamination was performed using egg-surface contamination or immersion-water contamination. For F. psychrophilum and R. salmoninarum, infection occurred by the entr...
