We provide a detailed comparison of the two-dimensional, temporal and spatiotemporal linearized analyses viscoelastic free shear flows in limit low to moderate Reynolds number Elasticity obeying four different types stress-strain constitutive equations: Oldroyd-B, Upper Convected Maxwell, Johnson-Segalman (JS) linear Phan-Thien Tanner (PTT). The resulting fourth-order Orr-Sommerfeld Equation is...

background: obesity seems to be associated to migraine headache. increase in body fat, especially in gluteofemoral region, elevates adiponectin and leptin secretion which in turn impair inflammatory processes that could be contributing to migraine risk. this study was designed to assess the relationship between body composition and risk of migraine for the first time. methods: in this cross-sec...

in order to determine the responses of morphological characteristics, yield and yield components of rapeseed (brassica napus l.) to plant density and weed interference duration, a factorial experiment was conducted using a randomized complete block design with 3 replications at the rice research institute of iran (rrii) in rasht, in the 2008 growing season. the factors comprised plant density a...

Transverse thin cell layer sections excised from in vitro scales of Lilium ledebourii were cultured on Murashige and Skoog (MS) medium supplemented with various plant growth regulators (PGRs) at different concentrations. Although, bulblets were produced on PGRfree MS medium during organogenesis, addition of 0.25 mg l-1 6-benzyladenine or 5.0 mg l-1 indole-3-acetic acid to the medium increased t...
