fire-retarding properties of wollastonite nanofibers in poplar wood (populus nigra) were studied here. some physical properties such as water absorption, volumetric swelling and anti-swelling efficiency (ase) were also measured. specimens were prepared according to the iso 11925 specifications for the fire-retarding properties and according to the astm d4446 -2002 specifications for the physica...
Overview The structure of these patterns is similar to the one introduced by Andreas Rueping [6] . The problem section formulates an issue as a question. The forces are the considerations that lead to the solution. The solution answers the question of the problem section. In the discussion section, some examples are presented or drawbacks of the solution are discussed. Some of the patterns have...
effects of heat-transferring property of silver nanoparticles were evaluated on two solid woods of poplar and fir and in combination with borax. nanosilver and borax were applied in pressure vessel using rueping method. the size range of silver nanoparticles was 20-80 nm. specimens of 150×130×9 mm were prepared and five fire-retarding properties were measured using a newly designed slide fire t...

Profound pharmacological benefits can be provided by site-selective incorporation of the deuterated “magic methyl” group, which considered an important tool for drug optimization and development. This review highlights trideuteromethylation strategies according to reagent used describes mechanism scope reactions. As such, this aims a guide researchers, offering them available C−CD3 formation pr...
abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...
