Nationalism of Friedrich Engels
No full textU članku se autor zalaže za to da se komunistička i nacionalistička teorija tretiraju kao dve kolektivističke teorije koje imaju mnogo dodirnih tačaka i tesnih veza. Daleko do toga da su 'smrtni neprijatelji', ove dve teorije pokazuju značajnu obostranu privlačnost i daju osnove za uspon totalitarnih projekata u 20. veku. Želeći da pruži doprinos ovom gledištu, autor analizira nacionalističke elemente u radovima Friedricha Engelsa.In this article the author argues that communist and nationalist theories should be treated as two collectivist theories which have many common topics and firm connections. Far from being 'mortal enemies', this two theories show considerable mutual attraction and give grounds for the rise of totalitarian projects in the 20th century. In order to give a contribution to this viewpoint, the author analyses the nationalist elements in the works of Friedrich Engels
Does a nucleus act like a gluon filter?
No full textKrzywicki A, Engels J, Petersson B, Sukhatme U. Does a nucleus act like a gluon filter? Physics Letters, B. 1979;85(4):407-412.We study large-pT hadron production off nuclear targets in the framework of the QCD inspired parton model. The anomalous nuclear enhancement is interpreted as being due to multiple scattering of partons. The curious trigger dependence of the enhancement results mainly from a particularly intense multiple scattering of gluons. This is a novel and interesting observable manifestation of the existence of the gluon self-coupling

Die Staats- und Rechtsauffassung von F. Engels in ihrer Bedeutung fuer den sozialistischen Staat und das sozialistische Recht Kolloquium der Sektion Staats- und Rechtswissenschaft der Martin-Luther-Universitaet Halle-Wittenberg aus Anlass des 165. Geburtstages von F. Engels
No full textDie Beitraege zu dem Kolloquium wuerdigen die Bedeutung des Werkes von F. Engels fuer die Begruendung und Entwicklung des dialektisch-materialistischen Staats- und Rechtsdenkens. Auch wenn umfangreiche juristische Untersuchungen im Werk von Marx/ Engels fehlen, so schufen doch die 'staats- und rechtsphilosophischen Ansatzpunkte ein Fundament fuer die wissenschaftliche Weltanschauung der Arbeiterklasse'. Die Referate befassen sich u. a. mit Aspekten der wissenschaftlichen Methode in Engels' Werk, mit dessen Auswirkungen auf die sozialistische Konzeption der Umweltgestaltung, den Aussagen zur Entstehung des Grundeigentums bei den Germanen und der asiatischen Produktionsweise.

A Dynamic Subfilter-scale Stress Model for Large Eddy Simulations Based on Physical Flow Scales
No full textWe propose a new definition of the length scale in an eddy-viscosity model for large-eddy simulations (LES). This formulation extends and generalizes a previous proposal [Piomelli, Rouhi and Geurts, Proc. ETMM10, 2014], in which the LES length scale was expressed in terms of the integral length-scale of turbulence determined by the flow characteristics and explicitly decoupled from the simulation grid; this approach was named Integral Length-Scale Approximation (ILSA). As in the original ILSA, the model coefficient was determined by the user, and required to maintain a desired contribution of the unresolved, subfilter scales (SFS) to the global transport. We propose a local formulation (local ILSA) in which the model coefficient is local in space, allowing a precise control over SFS activity as a function of location. This new formulation preserves the properties of the global model; application to channel flow and backward-facing step verifies its features and accuracy
Large-eddy simulation of a separated flow with a sub-filter scale model based on the integral length-scale
No full textA new sub-filter scale model for large-eddy simulations, which uses a length-scale proportional to the integral scale of the turbulence instead of the grid resolution to parametrize the modelled stresses, will be assessed in the prediction of the flow of a boundary-layer over a rough surface, which includes separation and reattachment
Near Wall PIV-Measurements on the Windward Slope of a Hill
No full textThe turbulent flow over periodic hills was measured near to the wall, using planar Particle-Image-Velocimetry (PIV) at high spatial resolution. Our focus is on the near wall turbulence structure on the windward slope of the hill. For large-eddy simulation (LES) we suspect that, if this was not predicted accurately, it affects the prediction of the velocity profiles over the hill crest which in turn will affect the recirculation length downstream of the hill. Regarding the time averaged velocities, we were able to resolve the linear viscous region of the boundary layer. The velocity distribution and also the Reynolds stress does not comply with the law of the wall as it is valid for a turbulent boundary layer at equilibrium
