In this work, leakage radiation from EA200 series electron applicators on Siemens Primus accelerators is quantified, and its penetration ability in water and/or the shielding material Xenolite-NL established. Initially, measurement of leakage from 10 x 10 - 25 x 25 cm2 applicators was performed as a function of height along applicator and of lateral distance from applicator body. Relative to ce...

to study the effect of sucrose and calcium chloride on the quality and longevity of cut flower of rose cv. varlon, this experiment was conducted at the faculty of agriculture, zanjan university, zanjan, iran, in 2007. cut flowers were received from mahallat ornamental plants and flowers research station. experimental factors included: sucrose at four levels (0, 40, 80 and 100 mg/l) and calcium ...

Estimating the magnitude of Agulhas leakage, the volume flux of water from the Indian to the Atlantic Ocean, is difficult because of the presence of other circulation systems in the Agulhas region. Indian Ocean water in the Atlantic Ocean is vigorously mixed and diluted in the Cape Basin. Eulerian integration methods, where the velocity field perpendicular to a section is integrated to yield a ...

Pipelines are typically used to transport oil, natural gas, water, etc. It is one of the most effective methods for transferring fluids over long distances. However, long-term usage these pipes without maintenance results in formation residues, which will pave way pipeline accidents and soil contamination. To ensure safety protection resources, sustainable pipelines need be inspected avoid loss...

introduction: there are several methods for evaluating microleakage in dentistry, for example dye or bacterial leakage, electro-chemical methods, radioisotope labeling and fluid filtration. the purpose of this study was to assemble the fluid filtration system for quantitative evaluation of microleakage in dental materials. materials and methods: the roots were connected to a tube filled with an...
