Bacterial endophytes are beneficial to their hosts as they can fix nitrogen in the soil and make it available to the *** bacteria also secrete plant growth-promoting hormones to support their host plants under normal as well as stress *** current study aimed to isolate endophytic bacteria from different parts of Calotropis procera,i.e.,roots,stem and leaves of Calotropis procera(Ait.)*** were collected from the Lundkhwar,district Mardan.A total of 12 bacterial strains,i.e.,six from roots,three from the stem and three from the leaves were *** strains were screened for their growth-promoting activity in rice plants because rice shows a quick and easy response to the bioactive compounds present in the culture filtrate(CF)of the potent endophytic *** rice plants were cultivated in pots containing 30 mL of 0.8%w/v water-agar *** pots were placed in a growth chamber,operated at 28±0.3℃ for 14 h(day);and 25±0.3℃ for 10 h(night),at 70%*** the isolated strains,R1,S1,S3,L1,R5 and R6 showed visible growth promotion in rice *** biochemical analysis revealed that the strains were able to produce indole acetic acid(IAA)and flavonoids in higher ***,the strains also produced bioactive compounds that inhibited the growth of Escherichia coli and Aspergillus flavus using the well diffusion *** the results,it was concluded that these strains can secrete potent compounds that can promote the host plant growth and inhibit the growth of pathogenic microorganisms and,therefore,can be used as bio-fertilizer and bio-control agents.

APPROXIMATE SOLUTION OF INTEGRAL EQUATIONS AND CONVOLUTION INTEGRALS USING LEGENDRE POLYNOMIALS

引用

Analysis in Theory and Applications 1997年第2期13卷 11-19页

It has been argued that Chebyshev polynomials are ideal to use as approximating functions to obtain solutions of integral equations and convolution integrals on account of their fast convergence. Using the standard deviation as a measure of the accuracy of the approximation and the CPU time as a measure of the speed, we find that for reasonable accuracy Legendre polynomials are more efficient.
