In this paper we qualitatively study radial solutions of the semilinear elliptic equation $\Delta u + u^n = 0$ with $u(0)=1$ and $u'(0)=0$ on positive real line, called Emden-Fowler or Lane-Emden equation. This is great importance in Newtonian astrophysics constant $n$ polytropic index. By introducing a set new variables, can be written as an autonomous system two ordinary differential equation...

The catalyst for this paper is the recent interest in the relationship between social networks and an individual's health, which has arisen following a series of papers by Nicholas Christakis and James Fowler on person- to-person spread of health behaviors. In this issue, they provide a detailed explanation of their methods that offers insights, justifications, and responses to criticisms. In t...

Faith development theory was pioneered originally in the 1970s (Fowler, 1974) and 1980s (Fowler, 1981) as a framework for understanding the evolution of how human beings conceptualize God, or a Higher Being, and how the influence of that Higher Being has an impact on core values, beliefs, and meanings in their personal lives and in their relationships with others. Because of the formative influ...

Previous studies have found that both political orientations (Alford, Funk, and Hibbing 2005) and voting behavior (Fowler, Baker, and Dawes 2008; Fowler and Dawes 2008) are significantly heritable. In this article we study genetic variation in another important political behavior: partisan attachment. Using the National Longitudinal Study of Adolescent Health, we show that individuals with the ...

OBJECTIVES The present study investigates the outcome of Fowler-Stephens operation in prepubertal Wistar rats focused on microlithiasis and Leydig cell hyperplasia development. METHODS Thirty-eight (38) animals underwent laparoscopic Fowler-Stephens operation on the right testis (8 of them formed the control group) and 6 of them additional contra-lateral orchectomy. The testes were examined h...

The density of emission current by a rough surface with fractal structure is analyzed. A possible experimental setup is modeled by an irregular emitting surface, iteratively generated by a fractional Brownian motion FBM algorithm with roughness or Hurst exponent H=0.3 and a far away plane representing the anode. The boundaries are held at a fixed potential difference and the Laplace’s equation,...

This article aims to mark out new conditions for oscillation of the even-order Emden–Fowler neutral delay differential equations with term ?1???[?r?1?]?+?3???[???]=0. The obtained results extend, and simplify known in literature. are illustrated examples.

Dysyncritus Fowler is revised based on the examination of primary types, and restructured to exclusively accomodate Dysyncritus intectus Fowler, 1895. Allodrilus Evangelista gen. nov. (type species: Cymbomorpha nitidipennis Funkhouser, 1922 = Allodrilus nitidipennis (Funkhouser, 1922) comb. nov.) is erected with seven newly discovered taxa: A. alboferrugineus Evangelista sp. nov. (Brazil, Colom...

V L Katkov and V A Osipov Joint Institute for Nuclear Research, Bogoliubov Laboratory of Theoretical Physics, 141980 Dubna, Moscow region, Russia Abstract The field emission of crystalline AAA graphite is studied within a simple analytical approach with account of the exact dispersion relation near the Fermi level. The emission current is calculated for two crystal orientations with respect to ...

Abstract In this work, kaolinite clay was modified with magnetic magnetite nanoparticles (Fe 3 O 4 @MC) by co-precipitation ferrous and ferric ions as iron precursors to ameliorate its textural adsorption capacity for methylene blue (MB) dye uptake from synthetic wastewater at low concentrations. The adsorbents were characterized using XRD, BET surface area analysis, VSM, SEM HRTEM. after chemi...
