Novel fungal endophyte (Neotyphodium coenophialum; Latch, Christensen and Samuels; Glenn, Bacon, and Hanlin) genotypes in symbiosis with tall fescue (Lolium arundinaceum; Schreb. Darbysh.) have been recently introduced to agricultural seed markets. These novel endophytes do not produce the full suite of toxins that the ‘common toxic’ form does, and… (More)
The CAPM as the benchmark asset pricing model generally performs poorly in both developed and emerging markets. We investigate whether allowing the model parameters to vary improves the performance of the CAPM and the Fama-French model. Conditional asset pricing models scaled by conditional variables such as Trading Volume and Dividend Yield generally… (More)
ited on sandy or on loamy sediments. Therefore, it is important to study not only the extent of surface spatial Analysis and interpretation of spatial variability of soils is a key-variability, but also the distribution of subsurface and stone in site-specific farming. Soil survey maps may have up to 0.41-ha inclusions of dissimilar soils within a mapping… (More)
Purpose. The incidence of Clostridium difficile-associated diarrhea (CDAD) has steadily increased over the past decade. A multitude of factors for this rise in incidence of CDAD have been postulated, including the increased use of gastric acid suppression therapy (GAST). Despite the presence of practice guidelines for use of GAST, studies have demonstrated… (More)
OBJECTIVE This study examined the prevalence and risk factors for depression and anxiety in hospitalized cardiac patients in Pakistan.

Over the past 30 years, Land development and consumption have been out of control and expanding out of order, especially to marginal areas of some metropolises in Pakistan. In this research, the dynamic change of urban sprawl and its spatial and temporal characteristics was analyzed for Karachi division, Pakistan. To achieve the goal different image… (More)
In this paper, the preconditioned SOR and AOR methods are established for solving systems of linear equations. Ax b The convergence of the iterative methods are proved for L-matrices. The comparison with other preconditioned methods is given.
