determinant of the hankel matrix with binomial entries
abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.
15 صفحه اولthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولThe Microdetermination of Biological Copper with Oxalyldihydrazide.
Methods are described for the determination of microgram quantities of biological copper in aqueous medium as the intensely coloured oxalyldihydrazide-acetaldehyde complex (molar extinction coefficient 23,000 to 23,500). The methods are applicable on a routine basis to any biological material, in particular to serum, urine, or tissues, such as liver, brain, or kidney. In the case of urine a sim...
