Silicon has beneficial effects on growth, yield and improvement of the tolerance of some plants against biological and non-biological stresses. In order to study the effects of different concentrations of silicon (as Na2SiO3) on Iranian borage (Echium amoenum Fisch & C.A. mey), three levels of silicon (0, 0.2, 0.7 mM as Na2SiO3) and two levels of salinity (0 and 100 mM as NaCl) and two silicon-...
from the plants nutrition view point, silicon has not been recognized as an essential element but its useful effects on growth and development of many plants have been reported. in order to study the effect of application of different silicon on the yield component of wheat, an experiment was conducted in the city torbat heidarieh located in razavi khorasan province. the experiment was performe...
A simple way of making elastic tubes using a mechanical lathe for precise control of the wall thickness is proposed in this study. These tubes are particularly useful for modeling properties of large arteries. Tubes with different geometric parameters and hence different elastic behavior have been made with a silicon elastomer (Rhodorsil RTV 1556). They have been created to be used for complian...
Silicon is as an essential element for crops and an important food source for the growth of rice plant. If no adequate replacement for this element, plants are faced with a shortage of silicon causing serious eating disorder and instability in plant resistance to pests. This research was done to investigate the effect of silicon on growth, yield and tolerance to rice stem borer in Tarom Hashemi...
The University of Missouri Research Reactor has designed and constructed a thermal neutron beam line for use in small animal boron neutron capture therapy (BNCT) experiments. Details of the facility have been previously reported by Brockman et al.[1] and Pozzi et al.[2]. The facility utilizes a 15.24 cm diameter beam tube that extends from the beryllium reflector to the biological shield, a dis...
The main goal of the AEgIS experiment at CERN is to test the weak equivalence principle for antimatter. We will measure the Earth's gravitational acceleration g with antihydrogen atoms being launched in a horizontal vacuum tube and traversing a moiré deflectometer. We intend to use a position sensitive device made of nuclear emulsions (combined with a time-of-flight detector such as silicon μ s...
The adequacy of various nondestructive evaluation (NDE) techniques for inspecting silicon carbide heat-exchanger tubing is discussed .. These methods include conventional ultrasonics, acoustic microscopy, conventional and dye-enhanced radiography, holographic interferometry and infrared scanning techniques. On the basis of current test results and an examination of the discussions in available ...
