34 35 Limb movements can be driven by muscle contractions, external forces or intrinsic 36 passive forces. For lightweight limbs like those of insects or small vertebrates, passive forces 37 can be large enough to overcome the effects of gravity and may even generate limb 38 movements in the absence of active muscle contractions. Understanding the sources and 39 actions of such forces is theref...

In this study, a nickel (II) complex with 1,10-phenanthroline based ligand, [Ni(FIP)2](OAC)2 (1) with FIP = 2-(Furan-2-yl)-1H-Imidazole[4,5-f][1,10] phenanthroline as ligand was synthesized and characterized by spectroscopic methods and elemental analysis. The interaction of [Ni(FIP)2](OAC)2 (1) with calf-thymus DNA (ct-DNA) was studied by UV-vis absorption, fluorescence spectroscopies and visc...

Similar to random sea waves, forces on the offshore structures due to waves are random. These forces can be mainly divided into two components, namely, inline forces and transverse or lift forces. The random nature of lift forces is more complicated than that of inline forces and both should be combined for design purposes. In the present paper, two different approaches have been used to determ...

Fast rotating Wolf-Rayet stars are expected to be progenitors of long duration gamma-ray bursts. However, the observational test this model is problematic. Spectral lines originate in expanding stellar wind, therefore a reliable spectroscopical determination their rotational velocities difficult. Intrinsic polarization due modulation wind may provide an indirect way determine these stars. detai...
