This can of course be solved using algebra. The rst treatise on algebra was written by Diophantus of Alexandria in the 3rd century AD. The term derives from the Arabic al-jabr or literally \the reunion of broken parts." As well as its mathematical meaning, the word also means the surgical treatment of fractures. It gained widespread use through the title of a book ilm al-jabr wa'l-mukabala|the ...

Different parameters can be used together in the continuous casting process known as an important steel production stage world. It is to use metallurgical appropriate meet product properties. Many innovations have been made from past present. that studies are carried out on many effective topics such analysis, refractory materials, parameters, order make proper solidification will needs with it...

objective(s) several studies have reported improved response of exercised hearts to myocardial infarction (mi). this study was aimed to evaluate the preventive role of treadmill exercise and diosgenin on cardiac marker enzymes, thiobarbituric acid reactive substances (tbars), total antioxidant status (tas), lipids, and electrocardiographic (ecg) patterns in isoproterenol (iso)-induced myocardia...

Architecture definition, which is central to system design, one of the two most used technical processes in practice model-based systems engineering. In this article, a fundamental approach architecture definition presented and demonstrated. The success its application engineering problems depends on precise but practical term architecture. standard for description, ISO/IEC/IEEE 42010:2011, was...

We use Brownian motion ideas to study Schriidinger operators H = +A + V on Lp(R”). In particular: (a) We prove that limt+m t-l In /I e&H j111.9 is p-independent for a very large class of V’s where 11 A ll,,,n = norm of A as an operator from L’ to L”. (b) For Y > 3 and V E LY/~--E n L”Ip+c, we show that sup jl eetH Ilm,m -: (D if and only if H has no negative eigenvalues or zero energy resonance...
