Background: Eurasian Sparrowh.wks(Accipiter nisus) increasingly represent successful city-dwellers. Th.reby, a rich.food supply indicated by h.gh.numbers of small birds is believed to be th. key driver for th.s bird-eating raptor species to settle in urban environments. h.wever, as small passerine birds sh.w particularly strong antipredator responses, sparrowh.wks may not simply focus on patch.s of h.gh.st prey densities, but rath.r respond strategically to prey beh.vior, raising th. importance of oth.r parameters in determining th. occurrence with.n urban ***: To deepen our knowledge on h.bitat requirements of urban sparrowh.wks, bird surveys were carried out during winter between December 2005 and January 2017 in 36 city parks in Vienna, Austria. Besides food supply also park size, canopy h.terogeneity and th. connectivity with.oth.r green spaces were ***: Occurrence of sparrowh.wks was positively affected by increasing park size, prey density and th. interaction between both. Bird feeder density and park connectivity with.oth.r green spaces were of minor importance in explaining th. presence of th.s species. Canopy h.terogeneity didn't affect city park occupancy by Eurasian ***: Our results suggest th.t large city parks, particularly wh.n ch.racterized by h.gh.prey densities, substantially contribute to protect and preserve ecologically important bird species such.as raptors with.n th. urban environment—a landscape already struggling with.biodiversity losses and functional h.mogenization.

We consider an Adaptive Edge Finite Element Meth.d （AEFEM） for th. 3D eddy currents equations with.variable coefficients using a residual-type a posteriori error estimator. Both.th. components of th. estimator and certain oscillation terms, due to th. occurrence of th. variable coefficients, h.ve to be controlled properly with.n th. adaptive loop wh.ch.is taken care of by appropriate bulk criteria. Convergence of th. AEFEM in terms of reductions of th. energy norm of th. discretization error and of th. oscillations is sh.wn. Numerical results are given to illustrate th. performance of th. AEFEM.

Th. effect of structural order in th. parent alloy substrate on th. oxidation kinetics and oxide ph.se evolution was investigated for th. th.rmal oxidation of amorph.us Cu33at.%Zr67at.%and crystalline CuZr2 alloys of identical compositions in th. temperature range of 200–250?*** was found th.t,besides th. strong preferential oxidation of Zr in both.alloys,th. lack of structural order in th. amorph.us Cu33at.%Zr67at.%alloy results in much.slower oxidation kinetics,as well as in distinctly different microstructures of th. oxide overgrowth.and its Zr-depletion zone in th. wake of th. ZrO2 overlayer growth.*** experimental findings can be rationalized on th. basis of th. strikingly different atomic mobilities of Cu,Zr and dissolved O in th. amorph.us and crystalline alloys,wh.ch.also results in different nucleation barriers for crystalline oxide *** th.s obtained knowledge on th. underlying oxidation mech.nisms provides new and profound insigh.s into th. surface engineering of metallic alloys.
