In this paper, Oscillatory and asymptotic behaviour of solutions of a class of nonlinear fourth order neutral differential equations with positive and negative coefficients of the form (H) (r(t)(y(t) + p(t)y(t − τ))) + q(t)G(y(t − α)) − h(t)H(y(t − β)) = 0 and (NH) (r(t)(y(t) + p(t)y(t − τ))) + q(t)G(y(t − α)) − h(t)H(y(t − β)) = f (t) are studied under the… (More)

Organic functionalization of silicon holds promise for a variety of applications ranging from molecular electronics to biosensing. Because the performance and reliability of organosilicon devices will be intimately tied to the detailed structure of the organic adlayers, it is imperative to develop systematic strategies for forming and characterizing… (More)

Episodes of middle Cenozoic near-trench volcanism in California occurred during the transition from convergent to transform plate boundaries as segments of the East Pacific Rise intersected a subduction zone along western North America. Geochemical features of volcanic rocks from the Coast Range Province and Santa Maria Province, which represent two… (More)

In this paper oscillatory and asymptotic behavior of solutions of a class of nonlinear second order neutral differential equations with positive and negative coefficients of the form (r 1 (t)(x(t) + p 1 (t)x(τ (t))) ′) ′ + r 2 (t)(x(t) + p 2 (t)x(σ(t))) ′ +p(t)G(x(α(t))) − q(t)H(x(β(t))) = 0 and (r 1 (t)(x(t) + p 1 (t)x(τ (t))) ′) ′ + r 2 (t)(x(t) + p 2… (More)

Iowa State University conducted a convenience survey of biobased product companies in 2008, 2010, and again in 2012 to better understand some of the basic characteristics of companies that produce end-use biobased products and intermediate materials. The companies included in the 2012 survey were selected from a database of 3,467 companies populated by Iowa… (More)

Iowa State University conducted a convenience survey of biobased product companies in 2008 and again in 2010 to better understand some of the basic characteristics of companies that produce end-use biobased products and intermediate materials. The companies included in the 2010 survey were selected from a database of over 2,500 companies populated by Iowa… (More)
