The current understanding of astrophysical magnetic fields is reviewed with particular emphasis on nonlinear dynamo theory. Analytic and numerical results are discussed both for small scale dynamos, where helicity is unimportant, and for large scale dynamos, where kinetic helicity is crucial. Large scale dynamos produce small scale magnetic helicity as a waste product that quenches the large sc...

background and aims. different factors affect children’s behavior during dental treatment, including psychological and behavioral characteristics. the aim of this study was to evaluate the correlation of self-concept on child’s anxiety and behavior during dental treatment in 4 to 6-year-old children. materials and methods. a total of 235 preschoolers aged 4 to 6 years were included in this desc...

Small-scale dairy farming plays a pivotal role in the development of rural economies and has become key source for job creation poverty alleviation. However, survival rate these enterprises is compromised due to multifaceted challenges. As result, newly established or emerging small scale businesses are not sustainable. The objective this paper therefore investigate determinants affecting susta...

The Analytic Hierarchy Process (AHP) multicriteria method can be cognitively demanding for large-scale decision problems due to the requirement maker make pairwise evaluations of all alternatives. To address this issue, paper presents an interactive that uses online learning provide scalability AHP. proposed involves a machine algorithm learns maker’s preferences through small subsets solutions...

Classical lattice simulations of the Abelian Higgs model are used to investigate small-scale structure and loop distributions in cosmic string networks. Use of the field theory ensures that the small-scale physics is captured correctly. The results confirm analytic predictions of Polchinski and Rocha [29] for the two-point correlation function of the string tangent vector, with a power law from...
