Standing on a gently sloping straight beach, it is a matter of observation that various waveforms propagate on the surface of the sea. Among these we find edge waves water waves that progress along the shoreline. These waves, often difficult to visualize (this has, probably, prevented the regarding of this waveform as important for a long time), are coastal trapped, i.e. their amplitude is maxi...

distribution and abundance of plants has been correlated with a variety of complex environmental gradients. environmental factors affect plants growth and need to be understood by ecosystem managers. this study was carried out to examine the relationships between site factors and different vascular and non-vascular plants in north of iran. for this purpose, vegetation and soil sampling was perf...

The aim of the present study was to describe the relationships between macroinvertebrate traits and lateral hydrological and environmental gradients in a Mediterranean river-fl oodplain, from the main river channel to three disconnected fl oodplain wetlands. Bimonthly water and macroinvertebrate samples were collected from an array of riverine wetlands in the Ebro River in northeast Spain. Our ...

the relationship between some habitat factors and fish assemblage was analyzed in the taleghan river, alborz province, iran. fish specimens from thirty-three sites were sampled by electrofishing device in october 2014. the habitat parameters, including elevation (m), water depth (cm), river width (m), river slope (%), current velocity (m.s-1), number of large stone (> 15 cm), average stone diam...

Spin waves (SWs) have been studied experimentally and by simulations in 1000 nm side equilateral triangular Permalloy dots in the Buckle state (B, with in-plane ̄eld along the triangle base) and the Y state (Y, with in-plane ̄eld perpendicular to the base). The excess of exchange energy at the triangles edges creates channels that allow e®ective spin wave propagation along the edges in the B stat...

There has been increasing demand on psychodynamicially oriented therapists to empirically demonstrate the effectiveness of their interventions, and to associate these interventions with successful therapeutic outcome. Studies focused on psychoanalytic process have identified several process-related variables influencing the nature of the treatment and have demonstrated how therapy process chang...

Edge effects are increasingly important in British Columbia forests, as cutblocks become smaller and harvesting options with retention patches are more commonly used. This note summarizes edge effects for  ecosystem variables, including microclimate, soil chemistry, snow depth, windthrow, regeneration, vegetation, and animals, at the Sicamous Creek Silvicultural Systems project in a high-elev...

This paper considers the aeroelastic optimization of a subsonic transport wingbox under a variety of static and dynamic aeroelastic constraints. Three types of design variables are utilized: structural variables (skin thickness, stiffener details), the quasi-steady deflection scheduling of a series of control surfaces distributed along the trailing edge for maneuver load alleviation and trim at...
