In this article, we investigate oscillation and asymptotic properties for 3D systems of dynamic equations. We show the role of nonlinearities and we apply our results to the adjoint dynamic systems.
The study considers the relationship between shyness, some related personality variables and socio-economic status. Adolescent shyness levels are examined using two self-report questionnaires which cover the spectrum of inherent, emotional and situational shyness. These findings were correlated with individual levels of anxiety, neuroticism and also with… (More)
6 The large reservoir of antibiotic resistant bacteria in raw and treated water supplies is a matter of public health concern. Currently, the National Antimicrobial Resistance Monitoring Systems, a collaborative effort of the Centers for Disease Control, the US Department of Agriculture, and the US Food and Drug Administration, does not monitor… (More)
In the spotlight of this study is a particular type of first order dynamic initial value problem of the form u ∆ = f (t, u) + g(t, u), u(t 0) = u 0 , where f, g ∈ C rd [T κ × R, R] are nondecreasing and nonincreasing in u, respectively. A quasilin-earization technique utilizing the nature of natural lower and upper solutions as well as coupled lower and… (More)
