Nowadays, the real structures (considered as prototypes) subjected to fire are analysed by means of behaviours some reduced scale (defined models). These prototype–model correlations governed so-called dimensional analysis (DA) methods. methods, starting from Buckingham theorem, offer several dimensionless variables and based on them is Model Law (ML), which able foresee predictable prototype’s...
IntroductIon The main subject tackled in this article is the use of knowledge technologies to develop corporate memories or (stated more generally) " organizational memories " (OMs) (Dieng, Corby, Giboin, & Ribière, 1999). At the end of the 1990s, AI technologies, in general , and knowledge technologies, in particular, were recognized as pertinent and promising tools (in addition to information...
563 The formation of skeletal muscle tissue is directly modulated by intricate expressing the distinct signalling molecules orchestrated by the myogenic regulatory factors, such as the myogenic determination factor MyoD, that activates the transcription of muscle-specific genes by binding to consensus DNA sites found in the regulatory sequences of these genes, differentiate and fuse the myoblas...
It was a fine morning, Queen Victoria observed. After breakfast, she became aware of the crowds congregating outside Buckingham Palace. For this day of thanksgiving, 27 February 1872, the Queen's habitual widow's weeds were trimmed with miniver and her bonnet adorned with white flowers and a white feather. At 12.05 p.m., she took her place, together with the Prince and Princess of Wales and the...
in this investigation the effect of external field on the electron density of nanostructures of cds, cdse, cdte, gaas and polymeric structure of three, four, five and six units of cds as a kind of nanosolar cells has been studied theoretically. as modeling this system in nanodimension, molecular structures has used. specific properties of molecular structures permit us to consider different sym...

Theoretical framework: corporate (CSR) has become a decisive factor in business performance is consequential sustainable existence enterprises world's competitive environment (Buckingham, 2012; Mark, Yinyoung et ...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
abstract deviation or in other words committing a crime is literally a social problem. this research that was conducted in 1389 and 1390 has tried to investigate the causes of crimes committed by young male inmates qazvin central prison and effective variables on their tendency to deviation. accordingly after collecting theoretical framework and offering theoretical model including both hirsch...
